Medicine & Health news

Researchers identify possible new combination treatment for advanced melanoma

A study by researchers at the UCLA Jonsson Comprehensive Cancer Center suggests that using an immunotherapy drug called NKTR-214, also known as bempegaldesleukin, in combination with an infusion of anti-tumor immune cells, or T cells, may produce a stronger immune response that could help fight advanced melanoma.

Could resetting our internal clocks help control diabetes?

The circadian clock system (from the Latin "circa diem," about a day) allows organisms to anticipate periodic changes of geophysical time and to adjust to those changes. Nearly all cells comprise molecular clocks that regulate and synchronize metabolic functions to a 24-hour cycle of day-night changes. Today, increasing evidence show that disturbances in internal clocks stemming from frequent time zone changes, irregular work schedules and aging have a significant impact on the development of metabolic diseases in human beings, including type-2 diabetes.

How the immune system becomes blind to cancer cells

T cells play a huge role in our immune system's fight against modified cells in the body that can develop into cancer. Phagocytes and B cells identify changes in these cells and activate the T cells, which then start a full-blown program of destruction. This functions well in many cases—unless the cancer cells mutate and develop a kind of camouflage that let them escape the immune system undetected.

The scent of a rose improves learning during sleep

Effortless learning during sleep is the dream of many people. The supportive effect of smells on learning success when presented both during learning and sleep was first proven in an extensive sleep laboratory study. Researchers at the University of Freiburg—Medical Center, the Freiburg Institute for Frontier Areas of Psychology and Mental Health (IGPP) and the Faculty of Biology at the University of Freiburg have now shown that this effect can be also achieved very easily outside the lab. For the study, pupils in two school classes learned English vocabulary—with and without scent sticks during the learning period and also at night. The students remembered the vocabulary much better with a scent. The study was published in the Nature Group's Open Access journal Scientific Reports on 27 January 2020.

But what if exercise could benefit video game performance as well? A new study led by neuroscientist Dr. Marc Roig and his research team from the School of Physical & Occupational Therapy at McGill University, found, for the first time, that it can. The results of this study challenge the preponderant view that video gaming and physical activity are antagonistic activities. The findings were published online in the journal Medicine & Science in Sports & Exercise.

Fewer scars in the central nervous system

Neural stem and progenitor cells (NSPCs), from the so-called subventricular zone (SVZ), can help to repair a brain damaged by central nervous system disorders. It is known that the microenvironment within the SVZ directs the differentiation of stem and progenitor cells (NSPCs) toward cells in the nerve tissue. However, researchers have not yet been able to explain why NSPCs do not develop into neurons after injuries to the central nervous system, but rather into astrocytes. Astrocytes play a major role in the formation of scars and thus interfere with the regeneration of the nerves in the central nervous system. A team led by Prof. Dr. Christian Schachtrup and Lauriane Pous from the Faculty of Medicine at the University of Freiburg has now succeeded in analyzing a further step in these processes in the brain. The scientists present their results in the current issue of Nature Communications.

Congenital heart disease more deadly in low-income countries

Even though mortality from congenital heart disease (CHD) has declined over the last three decades as diagnosis and treatments have advanced, the chances for a child to survive a CHD diagnosis significantly differs based on the country where he or she is born.

Highly active HIV antibody restricts development of viral resistance

Antiretroviral drugs are the gold standard for the treatment of HIV infection. They are highly effective in suppressing replication of the virus but require lifelong daily application and can be associated with side effects. Due to the high mutability of HIV and its capacity for rapid adaptation, combinations of antiretroviral agents are required to prevent the development of drug resistance and treatment failure.

Religiousness linked to improved quality of life for people with HIV

Adults living with HIV in Washington, D.C., were more likely to feel higher levels of emotional and physical well-being if they attended religious services regularly, prayed daily, felt "God's presence," and self-identified as religious or spiritual, according to research published online Jan. 29, 2020, in Psychology of Religion and Spirituality. By contrast, patients living with HIV who had the lowest levels of quality of life and more mental health challenges were privately religious, potentially eschewing organized religion due to fears about being stigmatized or ostracized.

Escalating data from animal models are "fact-checking" the neurophysiological and behavioral correlates of the migraine experience in humans. A series of studies published in the journal Cephalalgia, the official journal of the International Headache Society, have described the underlying mechanisms and molecules related to migraine, and how they may be affected by current anti-migraine drugs or might translate into new therapies.

Virtual crossmatching improves quality of life for kidney transplant patients

Virtual antibody crossmatching is a safe and efficient way of selecting kidney transplant recipients. Two years after implementing the process, the Medical University of South Carolina (MUSC) division of transplant surgery, Charleston, concluded that the technique was just as accurate and sensitive as physical crossmatch, the current gold standard, and much quicker. Virtual crossmatching reduced the time kidneys were kept on ice while awaiting identification of a suitable recipient, improved scheduling for surgeons and operating room staff, and alleviated emotional and logistical stress on patients who were called to the hospital only to be sent home hours later after a more suitable recipient was identified. A study of the process and its effects on clinical and surgical practice outcomes appears in an "article in press" on the Journal of the American College of Surgeons website in advance of print publication.

The new study describes the first scientific evidence of a potentially invasive and colonial species –the marine bryozoan Membranipora membranacea- which reaches the Antarctic latitude islands in macroalgae that drift in the marine environment.

How do woodpeckers avoid brain injury?

Slamming a beak against the trunk of a tree would seem like an activity that would cause headaches, jaw aches and serious neck and brain injuries. Yet woodpeckers can do this 20 times per second and suffer no ill effects.

Efficient cryopreservation of genetically modified rat spermatozoa

Rat spermatozoa are two to four times larger than that of other animal species and are easily damaged by changes in pH, osmotic pressure, and temperature. Because these animals are very frequently used in medical research, a cryopreservation method was developed nearly 20 years ago. However, rat spermatozoa motility after thawing is extremely poor, and unless artificial insemination is performed at night (10:00-11:00 pm) no offspring will be produced. Furthermore, the number of offspring produced after successful artificial insemination is often lower than normal so the cryopreservation of rat sperm is not typically considered practical.

Not-so-dirty birds? Not enough evidence to link wild birds to food-borne illness

When food makes people sick, some blame birds because they hang around farms, and their feces can contain E. coli, Salmonella and Campylobacter, three common pathogens that can cause food-borne illness.

Simplifying simple sequence repeats

Simple sequence repeats (SSRs) are regions of DNA with high diversity, and they have long been a mainstay for botanists examining the genetic structure of plant populations. However, as the cost of sequencing DNA continues to plummet and genetic technologies advance, newer techniques for mapping genetic diversity such as genotyping-by-sequencing (GBS) or RAD-seq have begun to rival the traditional use of SSRs. In research presented in a recent issue of Applications in Plant Sciences, Dr. Mark Chapman optimized the process of identifying SSRs from genomic and transcriptomic data, helping to assure the continued use and relevance of SSRs in the age of high-throughput sequencing (HTS).
