Cancro da próstata e ejaculação?

Um estudo que indica menor incidência de cancro da próstata:
https://www.thesun.co.uk/living/3946845/orgasms-avoid-cancer-men-prostate-research/

Citando:
"In fact, in a study of almost 32,000 men published in the journal of European Urology, researchers found high levels of sexual activity can reduce the risk of contracting prostate cancer by 33 per cent.

The optimum number is 21 ejaculations per month which is equal to 252 times annually — or almost 70 per cent of days in a year.

Experts aren’t exactly sure why ejaculation lowers the risk of prostate cancer, but they speculate it might help flush out cancer-causing toxins.

In the UK alone, 40,000 men are diagnosed with prostate cancer every year – and there are 11,000 deaths-a-year.

It is also the third deadliest cancer in the UK and the disease develops slowly, meaning many men don’t know they have it for several years.

Prostate cancer currently kills 10,900 men a year and Prostate Cancer UK warn that this number could surge to 15,000 a year by 2026."

Prevenção de surdez (edição genética)

https://www.theguardian.com/science/2017/dec/20/breakthrough-for-genetic-hearing-loss-as-gene-editing-prevents-deafness-in-mice

Citando:
"Deafness has been prevented in mice using gene editing for the first time, in an advance that could transform future treatment of genetic hearing loss.

The study found that a single injection of a gene editing cocktail prevented progressive deafness in baby animals that were destined to lose their hearing.

“We hope that the work will one day inform the development of a cure for certain forms of genetic deafness in people,” said Prof David Liu, who led the work at Harvard University and MIT.

Nearly half of all cases of deafness have a genetic root, but current treatment options are limited. However, the advent of new high-precision gene editing tools such as Crispr has raised the prospect of a new class of therapies that target the underlying problem."

(...)

"The study, published in the journal Nature, focused on a mutation in a gene called Tmc1, a single wrong letter in the genetic code, that causes the loss of the inner ear’s hair cells over time.

The delicate hairs, which sit in a spiral-shaped organ called the cochlea, vibrate in response to sound waves. Nerve cells pick up the physical motion and transmit it to the brain, where it is perceived as sound."

Jejuns diversos?

Vários tipos de jejum, com benefícios para a perda de peso ou para a saúde (apesar dos escassos estudos científicos):

Citando:
"No “método 16/8”, basta fazer a última refeição às 20 horas, por exemplo. No dia seguinte, salta-se o pequeno-almoço. Ou seja, é um jejum de 16 horas, restando oito para a ingestão alimentar. Segundo a especialista, esta é a forma mais simples de seguir esta tendência.

Depois, tem o “método eat-stop-eat”, que é um jejum de 24 horas feito, no máximo, duas vezes por semana. Neste caso, pode, por exemplo, fazer do jantar a última refeição do dia. No dia seguinte, não pode comer nada até chegar novamente à hora de jantar.

E ainda há uma terceira forma: o “método 5:2”. Neste método só pode ingerir entre 500 a 600 calorias em dois dias não consecutivos da semana."

"Menu Correio da Manhã + Sub-categorias 3 EXCLUSIVOS PORTUGAL DESPORTO OPINIÃO BOA VIDA FAMOSOS Notícia Beber três a quatro cafés por dia faz bem à saúde Estudo revela benefícios do café. Por Catarina Figueiredo|24.11.17 + 1 / 8 Café Getty Images A questão é ambígua: se para muitos a ideia de consumir muito café por dia está associado a um deterioramento da saúde e do bem-estar físico, para outros, o consumo da cafeína significa um aumento da energia diária e vantagens saudáveis manifestadas a curto e a longo prazo. Assim, a revista científica BMJ publicou um estudo médico que desmistifica certas ideias sobre o café. A análise conclui que beber entre três a quatro cafés por dia reduz o risco de doenças hepáticas, como a cirrose, bem como acidentes cardiovasculares (AVC). No entanto, tal como tudo na vida, o consumo não deve ser exagerado e deve ser ajustado à condição de saúde do consumidor. No caso das grávidas, a ingestão de cafeína não deve exceder os 200 mg por dia, o equivalente a cerca de duas chávenas de café. A investigação, que esteva a cargo de Robin Poole, um especialista da área da saúde da Universidade de Southampton, no Reino Unido, revela ainda que as pessoas que consumem café têm um menor risco de contrair doenças como a diabetes, o cancro, a demência e o alzheimer. "

Citando:
"A radical radical  new cancer treatment inspired by patients who seem to ‘shrug off’ the disease could be tested next year.

The technique uses potent cancer-killing cells from people with the strongest immune systems.

These ‘neutrophil’ cells – which form part of the body’s first line of defence – are then multiplied millions of times and injected into cancer patients.

They are believed to be a key reason why rare individuals spontaneously reject lethal cancers and seem to have ‘miracle recoveries’."
(...)
"But when they do target cancer, they are highly efficient – wiping out 95 percent of test cancer cells in 24 hours. It is neutrophils with this ability that form the basis of the new therapy.

The Lift team has collected thousands of the cells discarded as a waste product by blood banks, and is mass-screening them for their cancer-killing potential in a laboratory.

Those that pass the test are cultured and multiplied many times over using a secret process. The researchers are also working on a way of altering them to become even more potent."

According to a report presented at the Royal Society of Medicine in London, the risk of liver cancer can be reduced with up to a 40 per cent with coffee consumption as compared to no coffee consumption, although this appears to be a dose-dependent relationship.

Also, that reduced risk is measured between 25 percent and 70 percent for cirrhosis.

Graeme Alexander, from the University College London in the UK, said, "Liver disease is on the rise and it is important that we understand how coffee, one of the most popular drinks in the world, and diet affect the disease", said."

Citando:
"Cientistas da Universidade George Washington da Califórnia, nos Estados Unidos, concluíram que tomar banho diariamente faz mal a saúde. Sim, o que para nós brasileiros é um ato de higiene, aos olhos dos cientistas é algo que prejudica a nossa saúde.

Segundo o estudo da Universidade, o banho diário afeta a camada mais externa da epiderme, chamada “camada córnea”. Esta camada mais fragilizada permite que os lipídios e os compostos gordurosos – que ajudam a manter a pele úmida – se dissolvam.

De acordo com o professor assistente de dermatologia da universidade Brandon Michell, o ideal é que o banho seja tomado uma ou duas vezes por semana. Mas, se o indivíduo quiser se banhar, o cientista recomenda que não seja necessário ensaboar o corpo inteiro.

Outro ponto levantado pelos cientistas é que a água quente causa secura e irritabilidade na pele, retirando do corpo as bactérias benéficas que ajudam no combate a infecções."

Sobre cortar com o açúcar - uma história

Citando:
"The constant bad news about sugar has suddenly got to me. There are stats showing that sugar consumption is at its highest level in history. The government is trying to get the food industry to cut the amount of sugar in popular products like chocolate bars by 20% by 2020.

I realise that I am the average UK adult, who consumes at least 15 teaspoons of sugar a day. (This may sound a lot, but there are seven teaspoons in just one fizzy drink can.) The World Health Organisation recommends eating just six.

A high-sugar diet is linked to obesity, and being overweight can increase the risk of getting Type 2 diabetes.A 2014 study found that there is a much higher risk of dying from cardiovascular disease among people who get a lot of their calories from added sugar."

Guerra dos antibióticos?

Desde 1980 que não se descobrem novos antibióticos:
http://www.bbc.com/news/health-21702647

E porque é que isso é importante? Porque desenvolvem resistência e porque são muito mais usados do que se pensa.
Citando:
"Antibiotics are more widely used than you might think and a world without antibiotics would be far more dangerous.

They made deadly infections such as tuberculosis treatable, but their role in healthcare is far wider than that.

Surgery that involves cutting open the body poses massive risks of infection. Courses of antibiotics before and after surgery have enabled doctors to perform operations that would have been deadly before.

Cancer treatments such as chemotherapy and radiotherapy can damage the immune system. A course of antibiotics is prescribed to provide a much-needed boost alongside your body's own defences.

Anyone with an organ transplant faces a lifetime of drugs to suppress the immune system, otherwise it attacks the transplant, so antibiotics are used to protect the body."

He said patients should not go to their doctor "expecting an antibiotic".

Instead, for infections that our body can handle, the advice is to:

have plenty of restuse pain relief such as paracetamoldrink plenty of fluids

"De acordo com um recente estudo publicado na revista Food Research Internation, e citado pela norte-americana Women's Health, a cebola roxa é aquela que ganha o estatuto de mais saudável pelo simples facto de ser ainda mais eficiente do que a cebola branca na hora de 'matar' as células cancerígenas e de combater a ação de todos os radicais livres que podem impulsionar o aparecimento da doença.

Mas, se tanto a cebola branca como a cebola roxa são aliadas na luta contra o cancro, porque é que esta última é ainda mais eficaz? Segundo o médico Suresh Neethieajan, tudo se deve à cor, uma vez que os elevados níveis de antocianina são os responsáveis pelo tom mais escuro da cebola roxa.

Contudo, e independentemente da cor, o consumo de cebola é sempre uma mais-valia para a saúde, não fosse este alimento rico em vitamina A, vitamina B2, vitamina B3, vitamina C, ferro, cálcio, potássio e também magnésio, um conjunto de micronutrientes que têm um impacto direto (...)"

A explicação foi agora publicada na revista Nature"
(...)
"Tal como as células humanas, a levedura contém uma proteína - a Ras – que pode tornar-se cancerígena após sofrer uma mutação. "Observámos na levedura que a degradação do açúcar está ligada à ativação de proteínas Ras através do intermediário Frutose-1,6-bisfosfato, que estimula a multiplicação tanto de células de fermento como de cancro. É impressionante que este mecanismo tenha sido conservado durante a longa evolução da célula de fermento para a célula humana", dizem os investigadores."

"Ketogenic diets are this year’s weight-loss silver bullet. While we should approach every diet with a healthy dose of skepticism, the more studies being conducted on ketosis—the state your body enters when producing elevated amounts of ketone bodies, which are constructed via fatty acid metabolism in your liver—the more the benefits are accruing. 

Weight loss is a continually trending topic, though such popular pastimes sometimes lead to deeper inquiry. In the case of ketogenic diets, two new studies published in Cell Metabolism show how cutting back carbohydrates and intermittent fasting not only helps with weight, but may stretch out your life while improving your memory along the way—in mice, at least. "

"Algumas marcas utilizam o dobro do sal e da gordura que outras que produzem produtos similares. A DGS poderá determinar metas para a reformulação da composição das bolachas.

Uma análise do Instituto Nacional de Saúde Doutor Ricardo Jorge (INSA) revelou que existem marcas de bolachas de água e sal e bolachas Maria – os dois tipos mais consumidos em Portugal – que utilizam o dobro do sal e da gordura que outras marcas que produzem produtos similares.

Os investigadores, que concluíram ser possível produzir os mesmos produtos com uma melhor qualidade nutricional, reforçam que é necessário serem "estabelecidas metas que permitam a reformulação gradual destes alimentos""

Citando:
"Em todos estes exemplos, o nutriente “engordante” pode ser a gordura, os hidratos, a proteína ou o álcool. Cada indivíduo engorda porque de alguma forma come mais calorias do que as que gasta, mesmo que não se aperceba disso. Um dos padrões mais recorrentes que surgem ultimamente são as semanas limpas e os fins-de-semana desastrosos, isto é, pessoas consciencializadas para se portarem bem durante a semana, mas todas as calorias que vão poupando de 2ª a 6ª, acabam por ser recuperadas ou no jantar de 6ª e sábado, ou no brunch de domingo, ou no casamento/aniversário do fim-de-semana, ou em qualquer roteiro gastronómico que acontece por norma nestes dias.

Concluindo, o que o engorda a si, não é o que engorda o seu colega do lado. O que ambos têm em comum é o excesso calórico. Descubra onde está a sua maior fragilidade alimentar e encontre estratégias para não se expor a ela."

Adoçantes artificiais e risco acrescido de diabetes tipo 2?

"Para isso, alguns dos 27 voluntários receberam o equivalente a 1,5 litros de uma bebida diet por dia, em forma de cápsula de dois adoçantes diferentes: sucralose e acessulfame K. Eles tomavam as cápsulas três vezes por dia durante duas semanas, antes das refeições. Os outros voluntários receberam placebo.

No final de duas semanas, testes mostraram que a resposta do corpo a glicose foi prejudicada. Este estudo apoia o conceito de que adoçantes artificiais podem reduzir o controle do organismo nos níveis de açúcar no sangue."

""Sanitation by boiling or microwave treatment has been shown to significantly reduce the bacterial load of kitchen sponges and can, therefore, be regarded as a reasonable hygiene measure. However, our data showed that regularly sanitized sponges (as indicated by their users) did not contain less bacteria than uncleaned ones," the researcher reveal.

Not only did some of the bacteria survive the sanitation process, the researchers found that those "sanitation resistant" strains were able to quickly infest the sponge again and could even increase the number of disease-causing bacteria.

The researchers admit that further analyses are needed to substantiate their findings, but they still advise against DIY sanitation of kitchen sponges because it may actually do more harm than good. Their short-term advice is to simply replace kitchen sponges on a regular, weekly basis."

"Although a surgeon’s goal is to remove cancer in its entirety during excision surgery, achieving negative margins (absence of cancer cells at the outer edge of the excised tumor specimen) can be challenging. To facilitate intraoperative diagnosis, Zhang et al.developed a handheld pen-like device that rapidly identifies the molecular profile of tissues using a small volume water droplet and mass spectrometry analysis. After 3 s of gentle physical contact with a tissue surface, the water droplet is transported to a mass spectrometer, which characterizes diagnostic proteins, lipids, and metabolites. The pen could be used to rapidly distinguish tumor from healthy tissue during surgery in mice, without requiring specific labeling or imaging and without evidence of tissue destruction."

"Amazon.com Review

Get ready to give up that morning latte and kiss cola goodbye. Here comes Caffeine Blues, by Stephen Cherniske, M.S., the first book to expose the dark side of America's No. 1 drug: caffeine. If you are one of the nearly 80 percent of Americans hooked on caffeine--a natural component of coffee, tea, and chocolate and a common ingredient in drugs, soda, candy, and other products--this book will be a wake-up call.

In Caffeine Blues, Cherniske, a nutritional biochemist with more than 25 years of academic research and clinical experience and author of the bestseller The DHEA Breakthrough, reveals the truth about caffeine and explains how to kick the habit forever. Cherniske discusses how caffeine affects the body and brain and why it can increase your risk of dozens of health disorders ranging from osteoporosis, diabetes, and PMS to hypertension and heartburn. After spending 300 pages documenting all of caffeine's evils, Cherniske finally offers a decaffeinated life line: "Off the Bean and on to Vitality," a step-by-step, clinically proven program to help readers kick the habit and boost energy levels naturally. --Ellen Albertson"

"Dr Sasaki concluded: “Our results support the hypothesis that sleep deterioration may lead to cardiovascular disease. Poor sleep in patients with ischaemic heart disease may be characterised by shorter sleep and brief moments of waking up.”

He added: “Difficulty maintaining sleep reflects an increase in sleep fragmentation, which refers to brief moments of waking up and causes overactivity of the sympathetic nervous system and adrenocortical axis.”

Previous research, published by the University of California San Francisco last year, suggests people who do not sleep all the way through the night are at a 29 per cent increased risk of developing an irregular heartbeat."

"The precuneus is connected to the dorsal attention network – an area responsive to attention demanding tasks, and the default mode network, the area which is activated during less mentally strenuous activity.

“When the default mode network is on, the dorsal attention network is off, and vice versa. We found that the precuneus in tinnitus patients seems to be playing a role in that relationship,” said Sara Schmidt, a graduate student in the university’s neuroscience program.

For those suffering from chronic tinnitus, the precuneus is more closely connected to the dorsal attention network, than the default-mode network, MRI scans showed.

The research suggests that tinnitus sufferers are “not truly at rest, even when resting”, said Fatima Husain, lead researcher and on the study and a professor at the university."

Cuidado com as dietas da moda (5-day cleansing)?

https://www.theguardian.com/lifeandstyle/2017/aug/11/why-we-fell-for-clean-eating

Citando:
"n the spring of 2014, Jordan Younger noticed that her hair was falling out in clumps. “Not cool” was her reaction. At the time, Younger, 23, believed herself to be eating the healthiest of all possible diets. She was a “gluten-free, sugar-free, oil-free, grain-free, legume-free, plant-based raw vegan”. As The Blonde Vegan, Younger was a “wellness” blogger in New York City, one of thousands on Instagram (where she had 70,000 followers) rallying under the hashtag #eatclean. Although she had no qualifications as a nutritionist, Younger had sold more than 40,000 copies of her own $25, five-day “cleanse” programme – a formula for an all-raw, plant-based diet majoring on green juice.

But the “clean” diet that Younger was selling as the route to health was making its creator sick. Far from being super-healthy, she was suffering from a serious eating disorder: orthorexia, an obsession with consuming only foods that are pure and perfect. Younger’s raw vegan diet had caused her periods to stop and given her skin an orange tinge from all the sweet potato and carrots she consumed (the only carbohydrates she permitted herself). Eventually, she sought psychological help, and began to slowly widen the repertoire of foods she would allow herself to eat, starting with fish. She recognised that the problem was not her veganism, per se, but the particularly rigid and restrictive diet regime she had imposed on herself.

As Younger slowly recovered from her eating disorder, she faced a new dilemma. “What would people think”, she agonised, “if they knew the Blonde Vegan was eating fish?” She levelled with her followers in a blogpost entitled Why I’m Transitioning Away from Veganism. Within hours of announcing her new diet, Younger was receiving irate messages from vegans demanding money back from the cleanse programmes and T-shirts they had bought from her site (featuring slogans such as “OH KALE YES”).

She lost followers “by the thousands” and received a daily raft of angry messages, including death threats. Some responded to her confession that she was suffering from an eating disorder by accusing her of being a “fat piece of lard” who didn’t have the discipline to be truly “clean”."

Efeitos da corrida no comportamento?

http%3A%2F%2Fwww.telegraph.co.uk%2Fhealth-fitness%2Fbody%2Fjogger-rage-runners-getting-aggressive1%2F#pt0-693851

Citando:
"How does running, which has a deserved reputation as an emotionally therapeutic exercise, cause such bile?

Much depends on which emotion you are aiming to address by going out in the first place. If you are feeling down, a run is often an effective way to cheer yourself up. It can also be a surprisingly efficient method of problem solving or dealing with mental blocks. As you stride along, your mind will clear, allowing you to see an issue in a completely new and positive way.

So far, so good - but the picture becomes quite different when people use a jog to try and burn off anger. That seething, aggressive energy may help someone run faster and longer, but heading out for a run with these sorts of emotions swirling inside you is a potentially lethal plan.
While running can sometimes ease anger, it can also make it worse because on a physical level, running and anger have plenty in common. Both will pump up your heart rate and blood pressure. They release adrenaline and stress hormones, as well as tensing up muscles. Testosterone rises too, which might explain why, in my experience at least, angry runners are always male.

All of this can send the angry runner into a vicious cycle. They start to feel more, not less, angry. This spurs them on to run faster and further. Their blood sugar levels are falling, which makes them even more irritable. Round and round they go – and heaven help anyone who gets in their way.

Another factor is that running can tune out your conscious brain, which means you begin to interact with the world in a more primal way. This is what can make runners territorial and aggressive on pavements. They respond to others in a way they would never dream of during a casual stroll.

Also worth noting is the potential for cowardice, which running shares with cycling and driving. It’s so much easier to bark an insult at someone, or push them out of the way, if you know you can simply run off and get away from quickly. "

They also looked at insulin sensitivity, insulin secretion, thickness of the carotid vessel wall and fitness.

The experts found that among the fat compartments, a low percentage leg fat mass was the strongest determinant of metabolic risk in lean subjects, while in obese subjects nonalcoholic fatty liver disease and increased intra-abdominal fat mass strongly determined this risk.

Based on these findings, the experts said that in lean subjects the problem of storing fat in the leg may be a crucial factor placing lean people at increased risk of cardiometabolic diseases."

"The study of 1,615 adults found that people who slept an average of six hours a night had a waist circumference three centimeters larger than those who slept nine hours a night (that’s about 1.18 inches). The short sleepers also had a higher BMI on average and lower HDL cholesterol (the so-called “good cholesterol” number that ideally should be higher).

Participants had blood samples taken and their waist circumference, weight and blood pressure recorded. Sleep times fell into three categories: average of about 6 hours, average of about 7.5 hours, and average of about 9 hours. Across the board, the 6-hour group had worse outcomes than the other two groups."
(...)
"The reasons why this is true are a topic of ongoing discussion, but two strong evidence-based possibilities are: (1) sleep deprivation handicaps self-control, little by little, resulting in food choices that pack on weight over time, and (2) lack of sleep, even in small amounts each night, disrupts hormones that regulate appetite, inducing hunger and triggering nighttime cravings that result in more weight gain."

Benefícios do exercício físico "mentais"?

Basicamente, nada como ser positivo:
http://time.com/4867746/exercise-fitness-positive-attitude/

Citação:
"Apparently, just thinking that you’re not exercising as much as you should may be harmful, too. In a new study in the journal Health Psychology, people who thought they were less active than their peers had a greater chance of dying younger—even if their actual activity levels were the same.

The research suggests that the health perks of exercise may come not just from the physical movements, but also how people think and feel about them, as well. In other words, people who feel like slackers may not be getting all the benefits they should be from their workouts."

Se bem que o que é verdade na Irlanda pode não o ser aqui e repetindo a notícia para compilar uma lista completa de motivos conhecidos pelos quais algumas pessoas são mais picadas que outras:

http://www.irishnews.com/lifestyle/holidays/2016/06/01/news/how-to-avoid-and-treat-mosquito-bites-on-holiday-542874/

Quoting:
"An estimated 10-20 per cent of people are highly attractive to mosquitoes and consistently get bitten more often than their counterparts.

• Research suggests that mosquitoes are attracted to exhaled carbon dioxide, as well as chemical compounds secreted in skin and sweat, including lactic acid, uric acid, ammonia, steroids, and cholesterol to name a few. 
• Certain bacterial species that naturally inhabit human skin, e.g. Staphylococcus epidermidis, make individuals more attractive to mosquitoes whilst others e.g. Pseudomonas aeruginosa, appear to have the opposite effect. 
• Research also suggests that certain blood types are more attractive to mosquitoes than others. A large number of the population secrete saccharides or sugars through the skin dependant on their blood type that mosquitoes are able to sense. 
• Studies suggest that mosquitoes seem to prefer those with Type O blood and land on skin with Type O blood nearly twice as often as those with Type A.
• Mosquitoes are also attracted to dark colours such as black and navy blue, as they use vision along with scent to locate their targets. It is best to dress in light colours such as white or pastels to reduce the risk of this.
• Pregnant women are more susceptible to bites. This is likely due to the fact that they exhale relatively more carbon dioxide and have a higher resting body temperature."

Homeopatia ou não homeopatia?

Provavelmente não, ver a história:
https://www.economist.com/blogs/economist-explains/2014/04/economist-explains?fsrc=scn/fb/te/bl/ed/whyhomeopathyisnonsense

Citando:
"The history of homeopathy – literally, “similar suffering” – dates back to the late 18th century. Samuel Hahnemann, a German doctor, was unimpressed by contemporary medicine, with good reason. Doctors used leeches to let blood and hot plasters to bring on blisters, which were then drained. In 1790, Hahnemann developed a fever that transformed his career. After swallowing powder from the bark of a cinchona tree, he saw his body temperature rise. Cinchona bark contains quinine, which was already known to treat malaria. Hahnemann considered the facts: cinchona seemed to give him a fever; fever is a symptom of malaria; and cinchona treats malaria. He then made an acrobatic leap of logic: medicines bring on the same symptoms in healthy people as they cure in sick ones. Find a substance that induces a symptom and it might be used to treat that symptom in another."
(...)
"One common designation is “NC”, where C signifies that a substance is diluted by a ratio of 1:100 and N stands for the number of times the substance has been diluted. So a dilution of 200C would mean that one gram of a substance had been diluted within 100 grams of water, with the process repeated 200 times. At this dilution not a single molecule of the original substance remains when the water is used to make pills; most homeopathic pills thus consist entirely of sugar. However, the water and the pills are supposed to retain a “memory” of the original substance.

This is nonsense. Studying homeopathy is difficult, points out the world’s biggest funder of medical research, the US National Institutes of Health (NIH), because it is hard to examine the effects of a medicine when that medicine has little or no active ingredient. Researchers can neither confirm that the medicine contains what it claims to nor show the chemical effect of the diluted medicine within the body. "
(...)
"The most comprehensive review of homeopathy was published in 2005 in the renowned medical journal The Lancet. Researchers compared trials of homeopathic and conventional medicines. In the bigger, well-designed trials, there was “no convincing evidence” that homeopathy was more effective than a placebo, they found. "

Privação do sono e impacto nos genes

http://www.bbc.com/news/health-21572686

Citação:
"So researchers [2013] at the University of Surrey analysed the blood of 26 people after they had had plenty of sleep, up to 10 hours each night for a week, and compared the results with samples after a week of fewer than six hours a night.

More than 700 genes were altered by the shift. Each contains the instructions for building a protein, so those that became more active produced more proteins - changing the chemistry of the body.

Meanwhile the natural body clock was disturbed - some genes naturally wax and wane in activity through the day, but this effect was dulled by sleep deprivation.

Prof Colin Smith, from the University of Surrey, told the BBC: "There was quite a dramatic change in activity in many different kinds of genes."

Areas such as the immune system and how the body responds to damage and stress were affected.

Prof Smith added: "Clearly sleep is critical to rebuilding the body and maintaining a functional state, all kinds of damage appear to occur - hinting at what may lead to ill health.

"If we can't actually replenish and replace new cells, then that's going to lead to degenerative diseases.""

"It highlights that although our body clocks are programming us to do certain things, we can't as we're ruled by social circumstances.

"We won't know the long-term consequences of this for many years."

Disrupted sleep in shift workers has been linked to a range of health problems, including type 2 diabetes.

Dr Reddy said the next wave of studies would gather data from activity and sleep monitors and "that's where the future of this is"."

"The key ingredient was "activity inequality" - it's like wealth inequality, except instead of the difference between rich and poor, it's the difference between the fittest and laziest.

The bigger the activity inequality, the higher the rates of obesity.

Tim Althoff, one of the researchers, said: "For instance, Sweden had one of the smallest gaps between activity rich and activity poor... it also had one of the lowest rates of obesity."

The United States and Mexico both have similar average steps, but the US has higher activity inequality and obesity levels."

The study analysed data from 800 older adults with an average age of 80 in the US.

Researchers found that generally, having a greater sense of purpose in life was associated with better quality of sleep, as well as a decreased likelihood of sleep disorders such as sleep apnoea and restless leg syndrome. "

Citando:
"(...) Particles shed by several species of fungi (that we'd commonly think of as mould) can contain chemicals called mycotoxins, and that the toxins themselves can also become airborne.

For people with asthma and other allergies, the mould particles themselves can be a nightmare, inflaming the lungs and sinuses and causing anything from sneezing and itchy eyes to restricted airways and asthma attacks.

This is usually caused by the body's immune system becoming sensitive to compounds in the spores and hyphae or to waste products called microbial volatile organic compounds, and not specifically the mycotoxins.

Usually, mycotoxins are substances we'd associate with food contamination as they leach out of fungi growing on fruit or grains. Nobody is sure why fungi produce them, but consumed in high enough concentrations they can be deadly.

While their effects on the body after being ingested have been studied extensively, less is known about the effect of breathing in mycotoxins, or whether it's even something to consider as a potential health concern for most of us.

"There is almost no data on toxicity of mycotoxins following inhalation,""

"A new three-in-one blood test could pave the way to precision-personalised treatment for advanced prostate cancer, say scientists.

The test has the potential to transform the way the disease is tackled by targeting specific gene mutations, it is claimed.

By looking for cancer DNA in blood samples, researchers were able to identify men with defective BRCA genes who were likely to benefit from a class of drugs called Parp inhibitors.

Breast cancer drug that can extend lives approved for NHS use
They also used the test to monitor DNA in the blood after treatment started, so patients who were not responding could quickly be switched to an alternative therapy.
Finally, the same test was used to pick up signs of evolving cancer showing the first signs of drug resistance."

Dos benefícios do exercício físico

https://www.publico.pt/2017/06/15/ciencia/noticia/exercicio-fisico-cansa-va-la-basta-uma-sessao-para-acordar-o-cerebro-1775665

Citando:
"O artigo conclui que os efeitos mais consistentes de uma só sessão de exercício físico são uma melhoria da função executiva (a capacidade de controlo e regulação de comportamentos), uma melhoria do humor e uma diminuição dos níveis de stress. Por outro lado, confirma-se também que há áreas e circuitos no cérebro com são activados com “exercício agudo”. Uma das mudanças, explica Wendy Suzuki, será um aumento da produção de novos neurónios no hipocampo, uma área do nosso cérebro que regista o nosso passado e também ajuda a imaginar o futuro. Ou seja, há uma área com um papel importante na memória e criatividade que é activada e estimulada com exercício físico.

Apesar de não parecerem restar quaisquer dúvidas sobre os benefícios do exercício físico no comportamento das pessoas, as neurocientistas sublinham que a relação entre a prática de desporto e as mudanças neuroquímicas tem sido estudada sobretudo em modelos animais e, por isso, defendem que esta deve ser uma área de estudo para investir no futuro.
