MU Research Sheds Light on Nerve Regeneration Following Spinal Cord Injury

COLUMBIA, Mo. – Fish, unlike humans, can regenerate nerve connections and recover normal mobility following an injury to their spinal cord. Now, University of Missouri researchers have discovered how the sea lamprey, an eel-like fish, regrows the neurons that comprise the long nerve “highways” that link the brain to the spinal cord. Findings may guide future efforts to promote recovery in humans who have suffered spinal cord injuries.

“There is a lot of attention to why, following a spinal cord injury, neurons regenerate in lower vertebrates, such as the sea lamprey, and why they don’t in higher vertebrates, such as humans,” said Andrew McClellan, professor of biological sciences in the College of Arts and Science and director of the UM Spinal Cord Injury Research Program (SCIRP).

Staphylococcus aureus bacteria turns immune system against itself

Around 20 percent of all humans are persistently colonized with Staphylococcus aureus bacteria, a leading cause of skin infections and one of the major sources of hospital-acquired infections, including the antibiotic-resistant strain MRSA.

University of Chicago scientists have recently discovered one of the keys to the immense success of S. aureus—the ability to hijack a primary human immune defense mechanism and use it to destroy white blood cells. The study was published Nov. 15 in Science. (more…)

Tritt fassen im Leben mit heissem Draht zur Klinik

Der Kanton Bern will die zu hohe Bettenzahl in psychiatrischen Kliniken abbauen. Dafür braucht es betreute Wohnheime (2. Teil).

Der überdurchschnittlich lange Aufenthalt in den Psychiatrischen Kliniken kommt dem Kanton Bern teuer zu stehen. Doch noch fehlen geeignete Wohnheime. Nun bahnt sich eine Lösung an: Werden Patienten nach der Entlassung weiterhin von der Klinik betreut, dann lassen sich auch Wohnplätze für schwierige Patienten finden. Und dann kann auch der Kanton Bern teure Klinikbetten abbauen. Die Stadt Winterthur hat es vorgemacht. (more…)

UA Study: Your Brain Sees Things You Don’t

A new study by UA doctoral student Jay Sanguinetti indicates that our brains perceive objects in everyday life of which we may never be aware. The finding challenges currently accepted models about how the brain processes visual information

University of Arizona doctoral degree candidate Jay Sanguinetti has authored a new study, published online in the journal Psychological Science, that indicates that the brain processes and understands visual input that we may never consciously perceive. (more…)

Zu langes Warten in der Klinik auf neue Chance (1)

Seit sie 20 wurde, lebt sie entweder in einer psychiatrischen Klinik oder im Gefängnis: «Die gleichen Patienten kommen und gehen.»

Nach einem Suizidversuch und der Einlieferung in die Psychiatrische Klinik mit 15 Jahren war ihr freiheitliches Leben zu Ende. Die heute 23-Jährige versucht seit Monaten vergeblich, ein Wohnheim zu finden, um im Leben wieder Tritt zu fassen.

Konzentriert mit dunklen wachen Augen, die dem Fragenden nie ausweichen, und mit fester Stimme, schildert die 23-jährige Rosa Meier* wie sie mit 15 Jahren erstmals in die Psychiatrische Klinik Waldau BE eingeliefert wurde und seither ihre Selbstständigkeit nie wieder erlangte. Der jüngste Versuch, den ersten Tritt für ein selbstständiges Leben in einem Wohnheim zu fassen scheiterte erneut. Nun lebt sie seit über vier Monaten wieder in der Klinik. «Mein Ziel ist, eine Wohngemeinschaft zu finden und eine Lehre anzufangen», sehnt sich Meier. Ihr Lebenslauf in Stichworten: «In der Familie erlebte ich Gewalt, landete auf der Gasse, nahm Heroin und Kokain. Eingeliefert wurde ich nach einem Suizid-Versuch und seither bin ich nie mehr wirklich heraus gekommen.» (more…)

Protein interplay in muscle tied to life span

Brown University biologists have uncovered a complicated chain of molecular events that leads from insulin to protein degradation in muscles and significantly diminished life span in fruit flies. The new study in PLoS Genetics, which may have broad implications across species, identifies the fly version of the mammalian protein activin as the central culprit in the process. (more…)

Results published in The Lancet give the most detailed picture yet of the British population’s sex lives over the last 10 years, as part of the third National Survey of Sexual Attitudes and Lifestyles (Natsal) survey.

Led by UCL in partnership with the London School of Hygiene & Tropical Medicine and NatCen Social Research, over 15,000 adults aged 16-74 participated in interviews between September 2010 and August 2012. (more…)
