Scientists use new non-invasive PET scanning method to monitor hippocampal neurogenesis

Scientists from the RIKEN Center for Life Science Technology in Japan have used a new non-invasive PET scanning technique to obtain images of neuron proliferation in the subventricular zone and subgranular zone of the hippocampal dentate gyrus. Neurogenesis in the hippocampal dentate gyrus is known to be particularly affected by depression.

Study shows how cancer cells pursue path toward greater concentrations of oxygen

Cancer cells need oxygen to survive, as do most other life forms, but scientists had never tracked their search for oxygen in their early growth stages until now -- a step toward a deeper understanding of one way cancer spreads that could help treat the disease.

PD-1-responsive T cells may offer clues to design more effective drugs for cancer

Cancer immunotherapy drugs that block the inhibitory PD-1 pathway have shown success in clinical trials and are now FDA-approved for melanoma, lung cancer and bladder cancer. Yet many patients' tumors do not respond to these drugs.

Researchers use personalized simulations of the brain to uncover nature of internal processes

The brain is an adaptable and highly complex system. However, much remains to be known about the way in which individual components of the brain interact in order to produce cognitive performance.

Scientists reveal new transmission path for yaws

Lesions on arms and legs, deformed faces - yaws is a tropical disease that infects the skin, bones and cartilage. It is caused by the bacterium Treponema pallidum subspecies pertenue

Metabolic-checkpoint inhibitor combination approach may improve cancer therapies

Reprogramming of the molecular pathways underlying normal metabolism is essential for T cell infection-fighting function and for the immune system to form a "memory" of the microbes it has already encountered. But exactly how metabolism in exhausted T cells is maintained in chronic infections and cancer is a missing element in this line of research.

Hyperkyphosis may be passed on from parents to children

Researchers from the Harvard affiliated Hebrew SeniorLife Institute for Aging Research recently published a study in the Journal of Bone and Mineral Research, suggesting that hyperkyphosis may be heritable, or passed on from parents to offspring.

Study reveals alterations in silent synapses could trigger drug-related memories in addiction

In addiction, cues in the environment can form strong associations with the drug of abuse. A new study in Biological Psychiatry suggests that alterations in silent synapses, inactive connections between neurons, could be the neural mechanism underlying the formation of these drug-related memories.

Scientists engineer therapeutic system with two arms to get better hold on cancer target

Scientists have engineered a sort of biological barbell that can get inside cancer cells and do damage to two proteins that work independently and together to enable cancer's survival and spread.

Biologists discover male-harming mtDNA mutant that substantiates mother's curse hypothesis

There is new evidence that the "mother's curse" - the possibility that moms may transmit genes to their children that harm their sons but not their daughters - holds true in animals.

New review highlights usefulness of BTMs in monitoring efficacy of osteoporosis treatment

A new review published by a joint scientific working group of the International Federation of Clinical Chemistry and Laboratory Medicine and the International Osteoporosis Foundation finds that current evidence continues to support the potential for bone turnover markers (BTMs) to provide clinically useful information for monitoring osteoporosis treatment.

E. coli bacteria capable of beneficial mutations at more variable rates than previously thought

Scientists studying how microbes evolve have long assumed that nearly all new genetic mutations get passed down at a predictable pace and usually without either helping or hurting the microbe in adapting to its environment.

Research finding opens door to potential clinical approaches that may boost body's ability to battle cancer

The microenvironment that supports a cancerous tumor also starves the immune cells that the body sends in to destroy the cancer, University of Pittsburgh Cancer Institute scientists revealed in a discovery that holds the potential to significantly boost the performance of breakthrough immunotherapy drugs.

Study finds how differences in vegetation in urban areas influence airborne microbial communities

New research finds that airborne bacterial communities differ from one urban park to the next but those of parking lots are alike -- and differ from those of parks in subtle but potentially important ways.

Lower weight late in life linked to greater risk for Alzheimer's disease

Researchers at Brigham and Women's Hospital and Massachusetts General Hospital have found an association between lower weight and more extensive deposits of the Alzheimer's-associated protein beta-amyloid in the brains of cognitively normal older individuals.

Next-generation sequencing to evaluate cell-free DNA yields more accurate results in diagnosis of MDS

Using next-generation sequencing (NGS) methods to analyze cell-free DNA in the blood of patients with myelodysplastic syndrome (MDS) yields more accurate results than the current standard approach of Sanger sequencing.

Researchers identify crucial innate immunity role for gene linked to ARC syndrome in children

UT Southwestern Medical Center researchers have found an important innate immunity role for a gene linked to a rare, fatal syndrome in children. Their study has implications for a much more common disease: tuberculosis.

UTA researchers find how changing estrogen levels make women more vulnerable to cocaine addiction

Researchers at The University of Texas at Arlington are studying how fluctuating estrogen levels make females increasingly sensitive to the rewarding effects of cocaine and ultimately, vulnerable to cocaine addiction.

Vaccines unsuccessful in protecting obese mice against influenza infections, study finds

A study led by St. Jude Children's Research Hospital found that obese mice are not protected against influenza infections by vaccines that include adjuvants, raising concerns about vaccine effectiveness in obese humans who are known to be at an increased risk for severe flu. The findings appear today in the scientific journal mBio.

Regular physical exercise could lead to higher brain volumes and decreased dementia risk

Using the landmark Framingham Heart Study to assess how physical activity affects the size of the brain and one's risk for developing dementia, UCLA researchers found an association between low physical activity and a higher risk for dementia in older individuals.
