Drug action in pancreatic cancer tracked and improved by nanotechnology
Oncology Nurse Advisor
Tiny biosensors used with new advanced imaging techniques are markedly improving drug targeting of solid tumors, according to new research. These new technologies work in real time and in three dimensions. They can show how cancers spread and how active cancer cells respond to a particular drug.More

New understanding of cellular movement may improve treatments for complex disease
Medical Daily
A new discovery about cellular movement within the body may provide insight into the disease mechanisms of metastasizing cancer or the constriction of airways caused by asthma. Like a school of fish or molecules of water, skin cells and others forming the body barrier are propelled by internal and external forces toward any unfilled spaces they encounter, according to researchers at Harvard School of Public Health and the Institute for Bioengineering of Catalonia.

Introducing the world's 1st brain tissue repository
Armed with Science
The Defense Department has established the world's first brain tissue repository to help researchers understand the underlying mechanisms of traumatic brain injury in service members. The announcement follows a symposium that Defense Secretary Chuck Hagel convened, in which a group of senior defense officials and experts in the medical field and from outside organizations discussed advancements and areas of collaboration regarding traumatic brain injury.

Genome instability studies could change treatment for cancer, other diseases
Penn State News
Counterintuitive as it may seem, genetic mutation is key to our evolution and survival. As our cells grow, reproduce, and die, DNA is repeatedly replicated and repaired, and bits and pieces of its sequences are perpetually changed, misplaced, and swapped in the process, thus producing mutations.

NSH featured Symposium/Convention workshop
NSH
Photoshop workshops are the most popular topics each year at the Symposium/Convention. This year, Workshop No. 7 — Photoshop Bootcamp is a three-hour course from 8-11:30 a.m. Sept. 21. Dr. Frank Mendel and Sandra Mendel will be discussing the difference between Photoshop and other image processing programs, how to adjust and improve digital images, and the basic selection tools in Photoshop. This is an introductory course, but you can fulfill all of your Photoshop needs, by taking Workshop No. 54 More Fun with Photoshop, for a more advanced look.

UC Davis researchers: A 2nd amyloid may play a role in Alzheimer's disease
Medical News Today
A protein secreted with insulin travels through the bloodstream and accumulates in the brains of individuals with type 2 diabetes and dementia, in the same manner as the amyloid beta Aβ plaques that are associated with Alzheimer's disease, a study by researchers with the UC Davis Alzheimer's Disease Center has found.

Study reveals genetic cause of high-arched palate
HealthCanal
Researchers at King's have revealed the genetic basis of high-arched palate in the mouth for the first time, a discovery that could pave the way for new treatments to reverse the condition. Published recently in Developmental Cell, an early study has shown that a particular gene in mice triggers an overproduction of neural crest cells (which generate a variety of important cell and tissue types in the body) whilst in the embryo, causing the roof of the mouth to be compressed into an arch shape.

Study finding shows which endometrial tumors may respond to progesterone
Oncology Nurse Advisor
A recent study has helped clarify which women with endometrial cancer are likely to benefit from progesterone therapy. Although this treatment can be effective and well-tolerated, it is not widely embraced in clinical practice due to the lack of biomarkers that predict hormone sensitivity and, subsequently, which patients will benefit from progesterone.

Stem cells provide novel technique to heal wounds, regenerate cells and prevent scarring
Medical Daily
A new skin generation technique to turn off cell death and then add stem cells improves wound healing by 80 percent. Skin regeneration after serious wounds often takes a long time. When skin grows back after an injury, a scar, marking the place of the once missing skin, can often remain. However, cell growth stem cells and their regulating proteins can potentially hold the key to scar avoidance and faster wound repair. More

Recent advances in the diagnosis and treatment of bladder cancer
BMC Medicine
Bladder cancer is the commonest malignancy of the urinary tract. In this review, the latest developments in the diagnosis and management of this condition is investigated. Cystoscopy and urine cytology are the most important tools in the diagnosis and follow-up of bladder cancer. Various alternatives have been investigated, either to reduce the frequency of cystoscopy, or improve its sensitivity for detection of tumors. More
