Ultraviolet Radiation Exposure Dose And Cataract In China

Many studies have reported ultraviolet (UV) radiation to be a risk factor for cataract. Although the onset of anterior cortical cataract has reported caused by UVB exposure through some animal experiments; most reports have assessed the application of much stronger UVB exposure than the normal daily exposure dose. To the best of our knowledge; no…

Nerve cell destruction

The Mystery Of ALS Frontotemporal Dementia

A special focus on rogue proteins may hold future promise in stopping the progression of nerve cell destruction in people who have amyotrophic lateral sclerosis (ALS); or frontotemporal dementia. ALS, a rare but devastating disorder that’s also known as Lou Gehrig’s disease; attacks the body’s nerve cells, resulting in progressive muscle weakness as the neurons…

Large Shortages In Primary, Specialty Physicians Seen by 2032

There could be a shortage of 46,900 to 121,900 physicians by 2032, in both primary and specialty care, with burnout potentially affecting retirement timing and a trend toward shorter working hours contributing to the wide range of estimates; hence a new report shows. The Association of American Medical Colleges (AAMC) on Tuesday release its latest…

Bladder cancer

Antitumoral Effect In Human Bladder Cancer Cell

Bladder cancer (BC) is a heterogeneous disease which presents several molecular characteristics associated with different clinical outcomes. Urothelial or transitional cell carcinoma (TCC); represent the most frequent type of bladder cancer and are classified into two subtypes tumors depending on the formation pathway: non-muscle invasive bladder cancer (NMIBC) or muscle-invasive bladder cancer (MIBC). NMIBC are…

Computational Modeling Of Lung Deposition Of Inhaled Particles

Chronic obstructive pulmonary disease (COPD) accounts for more than 3 million deaths every year. COPD is the 3rd leading cause of death globally and has enormous impact on the society; so patients and their families in terms of cost and quality of life. Tobacco smoking is the main cause for the development of COPD; but…

Same Brain Cells Active During Sleep and Exploration in Mice

Most brain neurons are active in waking; but hypothalamic neurons that synthesize the neuropeptide melanin-concentrating hormone (MCH) are; claimed to be active only during sleep; particularly REM sleep. Here we use deep-brain imaging to identify changes in fluorescence; of the genetically encoded calcium (Ca2+) indicator GCaMP6 in individual hypothalamic neurons; that contain MCH. An in-vitro…

For A Malnutrition-free India

In this election season, it is important to keep promises made not just to voters, but also those made to improve the lives of children, the future of the nation. Despite programme commitments since 1975, such as creating Integrated Child Development Services and national coverage of the mid-day meal scheme, India continues to grapple with…

Tummy Timetables: Physical Activity For Children Under Five

The United Nations on Wednesday released its first-ever recommendations on physical activity for children under five; with disputed advice on subjects ranging from screen time to “tummy time”. The guidelines from the World Health Organization may read to some parents like common-sense practices; including not exposing babies under one-year-old to screens. “This is about making…

Natural Disasters

News Coverage Of Violent Events May Contribute To 'Cycle of Distress'

In the wake of violent events like mass shootings or natural disasters, people who watch the most media coverage of the story are more likely to show post-traumatic stress symptoms months later, a small U.S. study suggests. After the 2013 Boston Marathon bombing and after the 2016 Pulse nightclub shooting in Orlando, Florida, researchers repeatedly…

Opioid-Related Depression

Identify Risk Factors For Opioid-Related Depression

A Saint Louis University researcher has received a grant to study the pathways from chronic prescription; opioid use to new onset mood disorder. “They hope our findings will inform pain management and safe opioid prescribing for patients with chronic, non-cancer pain,” Scherrer said. The grant will build upon Scherrer’s previous findings that indicate a new…

Plant Cells Eat Their Own Membranes and Oil Droplets

Biochemists at the U.S. Department of Energy’s Brookhaven National Laboratory have discovered two ways that autophagy, or self-eating; controls the levels of oils in plant cells. The study; published in The Plant Cell; describes how this cannibalistic-sounding process actually helps plants survive. It also provides mechanistic details scientists might leverage to get plants to accumulate…
