Harmless plant extract can help treat Cushing Disease

Cushing Disease, not to be confused with Cushing's Syndrome, is caused by a tumour in the pituitary gland in the brain. The tumour secrets increased amounts of the stress hormone adrenocorticotropin (ACTH) followed by cortisol release from the adrenal glands leading to rapid weight gain, elevated blood pressure and muscular weakness.

Public health researchers report frequency of two muscle-weakness disorders

Researchers in public health have reported in the first broad study in the United States the frequency of two muscle-weakness disorders that strike mostly boys: Duchenne muscular dystrophy and Becker muscular dystrophy.

Adolescents experience excessive daytime sleepiness due to marijuana use

A study published recently by researchers from Nationwide Children's Hospital, found 10 percent of adolescents sent to a Sleep Center for evaluation of excessive daytime sleepiness with testing results consistent with narcolepsy had urine drug screens positive for marijuana, confounding the results.

Discovery offers much needed information about how virulent insect-borne diseases cause infection

For decades, scientists have thought the bacteria that cause the bubonic plague hijack host cells at the site of a fleabite and are then taken to the lymph nodes, where the bacteria multiply and trigger severe disease. But UNC School of Medicine researchers discovered that this accepted theory is off base. The bacteria do not use host cells; they traffic to lymph nodes on their own and not in great numbers.

KU Leuven researchers find aggressive form of HIV in Cuba

Engaging in unprotected sex with multiple partners increases the risk of contracting multiple strains of HIV, the virus that causes AIDS. Once inside a host, these strains can recombine into a new variant of the virus. One such recombinant variant observed in patients in Cuba appears to be much more aggressive than other known forms of HIV.

Congressional briefing to focus on importance of including female subjects in medical research

The Endocrine Society and Society for Women's Health Research are co-sponsoring a Congressional briefing on February 17 that will focus on the importance of including female subjects in both preclinical and clinical biomedical research, which could potentially revolutionize medical research and scientific discovery.

Researchers demonstrate advantages of implanted defibrillator in preventing non-ischaemic heart failure

Sudden cardiac arrest is a possible cause of death in patients with non-ischaemic cardiac muscle weakness, i.e. a type of heart failure caused by genetics or for which no cause is known. Now, researchers at the University Department of Internal Medicine II at the MedUni Vienna (Clinical Department of Cardiology), as part of an international cooperation, have successfully demonstrated the advantages of an implanted defibrillator (ICD) as a means of prevention in patients with moderately restricted cardiac function, and that patients with the condition must be treated as carefully as patients with ischaemic heart failure which has developed following a heart attack, for example.

NTU Singapore setting up new institute to find cures for human diseases

Nanyang Technological University is setting up a new institute to advance research in the life sciences, with a focus on ramping up Singapore's efforts in finding cures for human diseases.

Study suggests introduction of specific NGF to prevent neuronal degradation in Alzheimer's patients

Scientists at Karolinska Institutet have evaluated a new Alzheimer's therapy in which the patients receive an implant that stimulates the growth of a certain type of nerve cell. The results, which are published in the scientific journal Alzheimer's & Dementia, suggest that the introduction of a nerve growth factor can prevent neuronal degradation in Alzheimer's patients.

Researchers report first evidence of Seoul hantavirus in wild rats in the Netherlands

In a paper just published in the peer reviewed journal Infection, Ecology & Epidemiology, researchers report discovering the first evidence of Seoul hantavirus (SEOV) in the wild rat population in the Netherlands. The discovery comes on the heels of similar ones in France, Belgium and the United Kingdom in recent years, and has some researchers concerned about the potential spread of the virus to humans.

Changes in moles and skin cancer: an interview with Dr Anjali Mahto, Consultant Dermatologist & British Skin Foundation Spokesperson

Melanoma is the 5th most common cancer in the UK and its incidence is continuing to increase since the mid-1970s. Cancer Research UK reports that its rates have increased more rapidly than any of the current ten most common cancers in males and females. Whilst some of this may be attributed to better surveillance and earlier detection, the real problem lies with sun-seeking behaviour and exposure to ultraviolet (UV) radiation.

New research shows that psychological factors affect treatment for back-related disability

People with back pain who have low expectations of acupuncture before they start a course of treatment will gain less benefit than those people who believe it will work, according to new research from the University of Southampton.

Study evaluates recent sleep trends for U.S. adolescents

Sufficient sleep is critical for adolescent health, yet the number of hours slept per night has decreased among teenagers in the United States over the last 20 years. A study by researchers at Columbia University's Mailman School of Public Health found that female students, racial/ethnic minorities, and students of lower socioeconomic status are particularly affected, with teens in these categories less likely to report regularly getting seven or more hours of sleep each night compared with their male counterparts, non-Hispanic white teenagers, and students of higher socioeconomic status, respectively.

Climate change causes emergence of more infectious diseases

The appearance of infectious diseases in new places and new hosts, such as West Nile virus and Ebola, is a predictable result of climate change, says a noted zoologist affiliated with the Harold W. Manter Laboratory of Parasitology at the University of Nebraska-Lincoln.

Researchers discover molecular 'switch' that controls replication, transcription of mitochondria DNA

A team of researchers led by Dmitry Temiakov, PhD, of the Rowan University School of Osteopathic Medicine (RowanSOM), has discovered a molecular 'switch' that controls replication and transcription of mitochondria DNA, a key finding that could influence the development of targeted therapies for cancer, developmental processes related to fertility and aging.

Widely used clinical calculators overrate heart attack risk

Most "risk calculators" used by clinicians to gauge a patient's chances of suffering a heart attack and guide treatment decisions appear to significantly overestimate the likelihood of a heart attack, according to results of a study by investigators at Johns Hopkins and other institutions.

Moffitt physicians promote novel screening strategies to decrease melanoma mortality

Melanoma, the most deadly type of skin cancer, was to blame for approximately 9,700 deaths in 2014. And with the number of melanoma cases increasing each year, it is believed that the disease could become one of the most common types of cancer in the United States by 2030. Promoting and developing national screening strategies may help to reduce deaths due to melanoma.

Breast density laws could pose risk of unnecessary procedures for women with breast cancer

Women with dense breast tissue are at increased risk of breast cancer. Dense breast tissue, generally defined as having more fibroglandular than fatty tissue, can make it more difficult for radiologists to detect cancer on screening mammography.

Study findings could help scientists better design silicon materials to improve chemotherapy drug delivery

A team of Israeli and American researchers have found that silicon nanomaterials used for the localized delivery of chemotherapy drugs behave differently in cancerous tumors than they do in healthy tissues. The findings could help scientists better design such materials to facilitate the controlled and targeted release of the chemotherapy drugs to tumors.
