New Microscopy That Observes The Evolution Of Cell Membrane Focal Adhesions

Researchers have developed a new form of microscopy that allows them to observe the formation and evolution of cell membrane focal adhesions. Focal adhesions are large specialized proteins that are located in the area where a cell membrane meets the extracellular matrix (ECM), a collection of molecules surrounding the cells that provide support and regulate micromechanical signals to the cells.The study was published in Light: Science & Applications.

Individual Cells Organize To Form Multi-layered Structures Of Embryo

Researchers have demonstrated the ability to program groups of individual cells to self-organize into multi-layered structures reminiscent of simple organisms or the first stages of embryonic development. A complex biological structures, an eye, a hand, a brain emerge from a single fertilized egg. This is the fundamental question of developmental biology, and a mystery still being grappled with by scientists who hope to one day apply the same principles to heal damaged tissues or regrow ailing organs. The study was published in Science.

Patient Preferences For Diagnostic Testing In The Emergency Department

Researchers hypothesized that a patient's willingness to undergo diagnostic testing is influenced by the potential benefit, risk, and personal cost. Patient preferences for diagnostic testing differed significantly across levels of risk, benefit, and cost of diagnostic testing, but cost was the strongest and most consistent factor associated with decreased desire for testing. The study was published in Academic Emergency Medicine (AEM), a journal of the Society for Academic Emergency Medicine (SAEM).

Cell Aging Could Prevent Diabetes

According to a new study, reserchers have discovered the effects of aging in our cells could allow doctors to cure or prevent diabetes, fatty liver disease, and other metabolic diseases and possibly even turn back the clock on aging itself. The new finding suggests that fatty liver disease and other unwanted effects of aging may be the result of our cells' nuclei, the compartment containing our DNA getting wrinkly. Those wrinkles appear to prevent our genes from functioning properly.

New Device For The Diagnosis Of Schizophrenia

A new study found portable device common in optometrists' offices may hold the key to faster diagnosis of schizophrenia, predicting relapse and symptom severity and assessing treatment effectiveness. Researchers used RETeval, a hand-held device developed to record electrical activity from the retina, to replicate and extend prior studies showing that people with schizophrenia had abnormal electrical activity in the retina. The study published in the Journal of Abnormal Psychology,

New Way To Control Blood Pressure

A new study found new and better ways to fight hypertension and low blood pressure may be in the offing. The team showed that Galectin-1, a protein in our body, influences the function of another protein known as L-type (CaV1.2) calcium channel found on the arteries that normally acts to contract the blood vessels. By reducing the activity of these calcium channels, Galectin-1 is able to lower blood pressure. The study was published online in Circulation.

PET Scans Help Tailor Therapy For Esophageal Cancer, Study Finds

Survival results for the CALGB 80303 Trial presented today at the American Society of Clinical Oncology (ASCO) Annual Meeting 2018 demonstrate that esophageal cancer patients are shown by PET scan to be non-responders to induction chemotherapy, and were then switched to a new chemotherapy during chemoradiation, showed the median overall survival of 27 months
