There is a new generation of serotonergic neurons from human multipotential stem cells

iStock_000019071669XSmallSu-Chun Zhang from the University of Wisconsin-Madison, a pioneer in the processing of stem cells into neurons, together with other scientists developed specialized nerve cells that produce serotonin (a neurotransmitter in the brain). The study was published in the Nature Biotechnology. Read full text »

Human epidermis was grown from stem cells

In laboratories of King’s College in London it was possible to grow epidermis with the use of stem cells. The epidermis is structurally and functionally similar to native one in humans. It has protective functions and permeability, thus it can be a natural barrier. The research was published in Stem Cell Reports in April 2014. Read full text »

Scientists discovered a new regulation mechanism of a human circadian rhythm

iStock_000024649569XSmallCircadian rhythm is responsible for proper functioning of an organism since it allows to adjust numerous inner processes to cyclically changing environmental conditions. Scientists from University of Manchester in Great Britain have recently discovered a new mechanism owing to which internal biological clock of human adapts more easily to existing external conditions.

Human serum albumin can be produced from rice seeds

Human serum albumin (HSA) plays a very important role in the human body and is used in many clinical cases. Because of the problems associated with its extraction researchers have been working on new methods of creating it. Proceedings of the National Academy of Sciences published the latest results of research on transgenic rice seeds from which HSA was isolated. Read full text »

Mobile phones – Human Phantom Vibration Syndrome

Human Phantom Vibration Syndrome (HPVS) is a new phenomenon on the verge of psychology and neurology that affects many users of mobile phones. It manifests itself differently but most commonly the owner a cell phone experiences the sensation of a vibration signal, although the device receives neither a message nor a call. The phenomenon has already been described in medical journals, however, there are very few studies on how often it occurs and what are the causes. Read full text »
