Tsukuba, Japan - While it is known that stem cells have the ability to develop into all tissues in a precisely regulated process, the way environmental cues affect stem cell behavior has remained poorly understood. In a new study, researchers from the University of Tsukuba discovered that neurons producing the neurotransmitter octopamine regulate the behavior of germline stem cells (GSCs) in response to environmental cues, such as mating.
Non-Cancerous Tissue from Nephrectomy Specimens: A Window into Kidney Pathology
CLEVELAND--Brain cell dysfunction in low oxygen is, surprisingly, caused by the very same responder system that is intended to be protective, according to a new published study by a team of researchers at the Case Western Reserve University School of Medicine.
Bottom Line: Among women participating in cervical cancer screening in Sweden, those with a diagnosis of invasive cervical cancer had an increased risk of iatrogenic injuries (as a consequence of medical intervention) and non-iatrogenic injuries (caused by accidents and self-harm) requiring hospitalization.
Journal in Which the Study was Published: Cancer Epidemiology, Biomarkers & Prevention, a journal of the American Association for Cancer Research
What The Study Did: Researchers examined the sociodemographic characteristics of patients associated with racial/ethnic differences in COVID-19 outcomes.
Authors: Bhramar Mukherjee, Ph.D., of the University of Michigan School of Public Health in Ann Arbor, is the corresponding author.

WEST LAFAYETTE, Ind. -- Getting run over by a car is not a near-death experience for the diabolical ironclad beetle.
How the beetle survives could inspire the development of new materials with the same herculean toughness, engineers show in a paper published Wednesday (Oct. 21) in Nature.
These materials would be stiff but ductile like a paper clip, making machinery such as aircraft gas turbines safer and longer-lasting, the researchers said.
LOS ANGELES -- An estimated 5.5 million people in the United States live with Alzheimer's disease, which is the most common form of dementia.
Keck Medicine of USC is enrolling individuals in an international phase 3 clinical trial to examine the safety and effectiveness of deep brain stimulation to treat Alzheimer's. The study uses electrical impulses to stimulate the region of the brain known as the fornix, which is associated with memory and learning.
Opioid use disorder affects about 2 million Americans each year and is the No. 1 cause of accidental death. Between 50 to 90 percent of individuals with this disorder were exposed to a prescription opioid first. Opioid use disorder is likely underdiagnosed within the healthcare system setting, which may be due in part to the reticence of practitioners who lack the specialized training in addiction medicine.
A gut hormone, ghrelin, is a key regulator of new nerve cells in the adult brain, a Swansea-led research team has discovered. It could help pave the way for new drugs to treat dementia in patients with Parkinson's Disease.
Blood-borne factors such as hormones regulate the process of brain cell formation - known as neurogenesis - and cognition in adult mammals.
Marine fish species are migratory in nature and not respectful of human-made territorial boundaries, which represents a challenge for fisheries management as policies tend to focus at the national level. With an average catch of 48 million tonnes per year, and USD $77 billion in annual fishing revenue, these species support critical fisheries, and require international cooperation to manage, according to UBC research.
In school bullying, there are people who are chronic victims. The acts of aggression that they experience are not limited to a particular moment or period of time, but rather part of a sustained process over a long period of time. These aggressions have much more serious consequences: chronic victims show higher levels of stress and personality issues that do not appear in students who have no connection to school bullying or those who have experienced it for shorter periods of time.
(Vienna, 21 October 2020) A recent study conducted by a research team led by Florian Kiefer from MedUni Vienna's Division of Endocrinology and Metabolism shows that cold ambient temperatures increase vitamin A levels in humans and mice. This helps convert "bad" white adipose tissue into "good" brown adipose tissue which stimulates fat burning and heat generation. This "fat transformation" is usually accompanied by enhanced energy consumption and is therefore considered a promising approach for the development of novel obesity therapeutics.
Volunteers from the Catholic Church in Brazil helped to mitigate the impact of COVID-19 among the elderly, a new study shows.
Peter Kevern, Professor Values in Health and Social Care at Staffordshire University, partnered with The Pontifical Catholic University of São Paulo to carry out the study which looked at the contribution of the Pastoral da Pessoa Idosa (PPI) programme in Brazil.
A new study led by scientists at IUPUI and Indiana University Bloomington is the first to describe a biochemical mechanism that increases the activity of a molecule whose presence is observed in many types of cancer.
