Newly engineered antibody attacks 99% of HIV strains

Newly engineered antibody attacks 99% of HIV strains

A team of scientists from the U.S. National Institutes of Health and pharmaceutical firm Sanofi claimed to have engineered an antibody capable of attacking 99 per cent of HIV strains and preventing infection in primates. The antidote attacks three key parts of the deadly virus, making it difficult for the virus to resist its effects.

The International Aids Society (IAS) called the engineered antidote an “exciting breakthrough” in the field of medical science.

High blood pressure reasons differ by gender: Study

High blood pressure reasons differ by gender: Study

A new study led by the American Heart Association (AHA) Council on Hypertension has revealed that reasons of high blood pressure differ by gender in teenagers as well as young adults.

Study author Catriona Syme, a postdoctoral fellow at the Toronto-based Hospital for Sick Children said blood pressure is mainly determined by three factors, viz. heart rate, stroke volume and the resistance to blood flow through the vessels.

Researchers find link between changes in brain chemistry and SIDS

Researchers find link between changes in brain chemistry and SIDS

A new study conducted by a team of researchers at University of Adelaide has confirmed that there is a strong link between abnormalities in a common brain chemical and sudden infant death syndrome (SIDS). The researchers examined 41 cases of deaths related to SIDS and found striking abnormalities in chemical serotonin in the brains of the victims.

Serotonin, which is also known as 5-HT, is a neurotransmitter in the central nervous system and many other parts of the human body. It plays several roles, including regulation of sleep and control of the cardiovascular system.

Low vitamin D levels linked to higher MS risk

Low vitamin D levels linked to higher MS risk

Deficiency of vitamin D puts a woman at a significantly higher long-term risk of developing multiple sclerosis (MS) than those who get enough, according to a new research.

In a case-control study, an increase in serum 25-hydroxyvitamin D was found to reduce the risk of MS by 39 per cent, after adjusting for sample year, number of pregnancies and births, and the matching factors.

Artificial sweeteners could raise risk of developing type-2 diabetes: Research

Artificial sweeteners could raise risk of developing type-2 diabetes: Research

Consumption of artificial sweeteners in large amounts could significantly raise the risk of developing type-2 diabetes (T2DM), a new research revealed. A team of researchers examined 27 healthy volunteers who were given a quantity of two different NAS (sucralose and acesulfame-K) equivalent to drinking 1.5L of diet beverage daily or an inactive placebo.

The volunteers were asked to consume in the form of capsules thrice a day before meals over a period of two weeks. At the end of the two weeks, the researchers examined the subjects again.

Harmful particles in tattoo ink travels to lymph nodes: Study

Harmful particles in tattoo ink travels to lymph nodes: Study

A large number of people around the globe love to get tattoos on various parts of their body and in varying sizes. But one should be careful as a new study has warned that this particular form of body art could cause health issues.

A team of researchers from Germany and France examined data collected by the European Synchrotron Radiation Facility (ESRF) to study how ink used in tattoos travels inside the body.

PSA screening saves lives with early detection of prostate cancer: Study

PSA screening saves lives with early detection of prostate cancer: Study

Prostate-specific antigen (PSA) screening significantly reduces the risk for death from deadly disease of prostate cancer as detection at early stage improves outcomes for patients, a new study claimed.

After disparities in settings and implementation were accounted for, two prostate cancer screening trials provide strong evidence that screening really decreases prostate cancer mortality rates.

Researchers develop camera capable of seeing through human body

Researchers develop camera capable of seeing through human body

A team of experts from Proteus EPSRC interdisciplinary research collaboration claimed to have developed a prototype camera capable of seeing through the human body. The camera that can see through the human body using light has been designed to help physicians track medical tools called endoscopes, which are commonly used to examine patients’ internal conditions.

Previously, it was not possible for doctors to track where an endoscope is located in the patient’s body. Sometimes they need to know such tools’ location to guide it to the right place.

Going gluten-free could be damaging for many in long term: Study

Going gluten-free could be damaging for many in long term: Study

Many individuals opting to go gluten-free could actually be doing themselves more harm than good, a new study has warned. Highlighting a Spanish study that found merely 16 per cent of people who self-reported gluten sensitivity really showed the symptoms in a proper trial; the new study warned that opting to go gluten-free might bring unnecessary risks if the person does not have celiac disease.

Research tells us why yawning is so contagious

Research tells us why yawning is so contagious

The human tendency for contagious yawning is triggered automatically by primitive reflexes in an area of the brain that is responsible for motor function, a new study revealed. It is commonly experienced that a person automatically yawns if someone nearby yawns. Now, a team of experts at the University of Nottingham claimed to have solved the mystery.

They found that the human intensity for contagious yawning is triggered involuntarily by an area of the brain called primitive reflexes in the primary motor cortex.
