Washington: In an editorial published in the New England Journal of Medicine (NEJM), Dr Debabrata Mukherjee provides expert commentary on bioresorbable stents, an alternative to the traditional stents used in patients with cardiac conditions. more

Scientists focus light on a key molecular family with regulatory roles in neurocognitive functions

Scientists focus light on a key molecular family with regulatory roles in neurocognitive functions

Puducherry: A new study conducted by Indian researchers has unravelled regulatory role of an exclusive family of molecules, Nerve Growth Factors (NGFs), in comprehensive neurocognitive functions and etiogenesis of neuropsychiatric disorders, raising hopes for preventive, rehabilitative and therapeutic use of these molecules in such disorders. more

Ultrasounds can decrease bone density: Study

Ultrasounds can decrease bone density: Study

Kuala Lumpur: Young rabbits exposed to ultrasound during foetal development had weaker thighbones than unexposed rabbits, according to a study published in the Pertanika Journal of Science & Technology. While the finding applies to a relatively small group of test subjects, 142 young rabbits, it raises questions about the rising use of prenatal ultrasounds in women worldwide. more

Washington: A majority of patients in the United States visited a doctor who received payments from drug companies, but most have no clue about it, according to a new Drexel University study. more

Study examines global burden of skin disease

Study examines global burden of skin disease

Washington: A study published in JAMA Dermatology estimates the global burden of skin disease as measured by disability-adjusted life years or DALYs, with one DALY equivalent to one year of healthy life lost. more

As radiation therapy declined so did second cancers in childhood cancer survivors

As radiation therapy declined so did second cancers in childhood cancer survivors

Washington: Childhood cancer survivors are living longer. Now research shows they are also less likely to develop second cancers while still young. The decline followed a sharp drop in the use of radiation therapy for treatment of childhood cancers. more

Quality of care does not differ between physicians and non-physician clinicians in community health centres: Study

Washington: A new study, published in Medical Care, examining patient health outcomes in community health centres found that nurse practitioners and physician assistants delivered care that was equivalent to care delivered by physicians. more

Light beam replaces blood test during heart surgery

Light beam replaces blood test during heart surgery

Washington: A University of Central Florida professor has invented a way to use light to continuously monitor a surgical patient’s blood, for the first time providing a real-time status during life-and-death operations. more

Scientists suggest new approach unravelling aetiology and possible reversal of complex psychiatric disorders

Scientists suggest new approach unravelling aetiology and possible reversal of complex psychiatric disorders

New Delhi: Aetiology of the complex psychiatric disorders remains elusive owing to unapproachability of intricate neural circuits in living human. Indian scientists have published a study in the journal ‘Neurology, Psychiatry and Brain Research’ proposing the possible use of an emerging advanced neuroscience research technique optogenetics in transgenic zebrafish model for understanding genesis, progression and possible reversal of various psychiatric disorders. more
