Small Populations Of Pathogenic Bacteria Is Harder To Kill

A new study shows that a population of bacteria containing 100 cells or less responds to antibiotics randomly not homogeneously like a larger population. Small populations of pathogenic bacteria may be harder to kill off than larger populations because they respond differently to antibiotics . The study was published in the journal eLife .

Services for Prevention and Management of Infertility in India

The National Institute for Research in Reproductive Health (ICMR-NIRRH) along with collaborative partners in India are in the process of developing guidelines for the prevention and management of infertility in the public health-care system.

To fill the gap in information on infertility related available services and management practices at different levels of public health system, this study was conducted to assess the availability and practices of prevention and management services for infertility in the district health-care system.

In addition, focus group discussions were also carried out to understand the perceptions of the community on various aspects of infertility. This paper pertains to health facility level findings on infertility prevention and management.

Heat Shock System: The Bug Came Back to Life After Drying up

The larva of the sleeping chironomid, Polypedilum vanderplanki — a mosquito-like insect that inhabits semi-arid areas of Africa — is well known for being able to come back to life after being nearly completely desiccated, losing up to 97% of its body's water content. Now, researchers have discovered that a gene called heat shock factor — which is present in some form in nearly all living organisms on earth — has been coopted by the species to survive desiccation.

Nuclear Receptor Defects in the Brain Linked to Autism

A portion of the hippocampus, called the dentate gyrus, responsible for memory and emotion, has been shown to be involved in autism spectrum disorders (ASD). Now, a team of scientists suggest that defects in the nuclear receptor called LXRβ (Liver X receptor Beta) lead to abnormal development of the dentate gyrus and to behavioral changes characteristic for ASD.

Protect Obese Women From Cardiovascular Disease

In this study, researchers assessed the hormone estrogen helps blood vessels stay healthy and pliable, but obesity further increases levels of another hormone that results in blood vessels that are instead inflamed, stiff and scarred. Youth keeps estrogen levels high, and being female also keeps levels of the hormone aldosterone naturally higher in females than males, which has a positive role in regulating blood pressure.

Cell Therapy: New Treatment for Alzheimer's disease

In the research, scientists uncovered the therapeutic benefits of genetically improving inhibitory interneuron, which can adequately control the activity of excitatory cells and restore brain rhythms by transplanting them into the brain of a mouse model of Alzheimer's disease,  

Genetic Variant Discovery Could Help Asthma and COPD Patients

A new study, published in the journal Lancet Respiratory Medicine, aimed to find genetic variants affecting susceptibility to corticosteroid-induced adrenal suppression. Research from the University of Liverpool identifies the genetic variant that could improve the safety and effectiveness of corticosteroids, drugs that are used to treat a range of common and rare conditions including asthma, and chronic obstructive pulmonary disease (COPD).
