Artificial blood vessel lets researchers better assess clot removal devices
An in vitro, live-cell artificial vessel has been created that can be used to study both the application and effects of devices used to extract life-threatening blood clots in the brain. The artificial vessel could have significant implications for future development of endovascular technologies, including reducing the need for animal models to test new devices or approaches.

Bacterial flora of remote tribespeople carries antibiotic resistance genes
Scientists have found antibiotic resistance genes in the bacterial flora of a South American tribe that never before had been exposed to antibiotic drugs. The findings suggest that bacteria in the human body have had the ability to resist antibiotics since long before such drugs were ever used to treat disease.

Fruit fly studies shed light on adaptability of nerve cells
Neurons in the eye change on the molecular level when they are exposed to prolonged light, new research demonstrates. The researchers could identify that a feedback signalling mechanism is responsible for these changes. The innate neuronal property might be utilized to protect neurons from degeneration or cell death in the future.

New genetic mutation could signal start of malaria drug resistance in Africa
Early indicators of the malaria parasite in Africa developing resistance to the most effective drug available have been confirmed, according to new research. Investigators found Plasmodium falciparum malaria parasites with a mutation to the gene Ap2mu were less sensitive to the antimalarial drug artemisinin.

Text messages a good way to support mothers with postpartum depression
New research explores the feasibility of helping low-income mothers through postpartum depression using text messages. The objective of the study was to evaluate the feasibility of sending supportive text messages to low-income mothers of racial and ethnic minority backgrounds with postpartum depression and gauge the perception of receiving such message for depression.

Two drugs reduce teacher-rated anxiety, in addition to ADHD, aggression
The addition of risperidone to parent training and a stimulant also improves teachers’ assessments of anxiety and social avoidance, new research shows. Improvement in teacher-rated anxiety and social withdrawal also contributed to improvements in parent-rated disruptive behavior. Children who showed reduced anxiety also showed less disruptive behavior.
