Doctor-patient dialogue is vital If diagnosed, the majority of respondents said they would actively work with their doctor to identi...

Focused ultrasound relieves fibroid symptoms in women

...y, we’ve learned that MRgFUS can be optimized with newer protocols to have even better results than previously thought possible," Dr. Tempany said. The findings showed significant symptom relief at three months and sustained relief at one year. Women treated with the optimized protocol reported greater ...

Chemical maps hint at drug's effects on schizophrenia

...is on lipid metabolism. Atypical antipsychotics, a newer group of prescription medications used to treat psychiatric conditions, have fewer side effects than the older antipsychotics, but several still induce weight gain and diabetes. Schizophrenic patients were found to have lower levels of the lipids ...

Bacterial walls come tumbling down

...ue of the journal Science. Penicillin and many newer antibiotics work by blocking a piece of the machinery bacteria use to construct their durable outer walls. Without these tough, protective coatings, bacteria die. The enzymatic machinery (known as PBP2) studied by Strynadka's group has two main parts...

NIAID DNA vaccine for H5N1 avian influenza enters human trial

...against such viruses. "This vaccine is aimed at newer strains of the H5N1 virus that currently pose a threat in Indonesia and represents an example of our ability to respond to shifting viruses with modern technology," says Dr. Nabel. The study will enroll 45 volunteers between the ages of 18 and 60....

Analysis of rhesus monkey genome uncovers genetic differences with humans, chimps

Cancer researchers add spice to research against rare neuromuscular disease

...in the course of that disease, opening the door to newer treatments. In 1988 Chang was the first to clone the androgen receptor, and he was the first to discover that the protein needs molecular allies called co-factors to accomplish many of its tasks. Now more than 70 co-factors are known, offering man...

Chromosomal microarray analysis proves accurate

For super-obese patients, duodenal switch beats gastric bypass

...rchers from the University of Chicago found that a newer operation, the duodenal switch, produced substantially better weight-loss outcomes than the standard operation, the Roux-en-Y gastric bypass.

MRSA vaccine shows promise in mouse study

...m multiple strains." The researchers turned to a newer technique, known as "reverse vaccinology," recently used to develop candidate vaccines against group A and group B streptococci and group B meningococci. Access to the S. aureus genome enabled the team to compile a list of cell-surface antigens from...

Results with newer bladeless LASIK equivalent to standard microkeratome LASIK

...lap is created by a blade; in bladeless LASIK, the newer type, the flap is created by a femtosecond laser. "At six months after surgery, there are no differences between the eyes that had bladeless or microkeratome LASIK with respect to visual acuity (vision as measured by reading an eye chart), contrast...

Scientists to employ Arctic ice and polar bears to protect diversity of world's crops

Cigarette smoke blocks cell repair mechanism, University of Florida study shows

...hose findings are increasingly being challenged by newer studies that are focusing on more than just single chemical components of tobacco, as past research often has done. In the UF study, researchers instead used a tar that contains all of the 4,000 chemicals found in cigarette smoke. "Our study sugges...
