MDI Biological Laboratory discover mechanisms underlying regeneration of heart tissue

The MDI Biological Laboratory has announced new discoveries about the mechanisms underlying the regeneration of heart tissue by Assistant Professor Voot P. Yin, Ph.D., which raise hope that drugs can be identified to help the body grow muscle cells and remove scar tissue, important steps in the regeneration of heart tissue.

Tailored new compound can dramatically reduce brain damage resulting from stroke

After suffering a stroke, about three-fourths of patients exhibit some disability. The extent of a patient's symptoms depends on the degree and location of brain tissue damage following the stroke event. This week in ACS Central Science, researchers show that by using a tailored small molecule to turn off the production of a key neuromodulator in the brain, they can dramatically reduce brain damage in stroke models in rats.

Early childhood presents short-lived window for intervention to ensure future cardio-metabolic health

Research conducted at LSU Health New Orleans School of Public Health has found that exposure to poverty does not produce metabolic and inflammatory biomarkers in young, healthy children. It identifies early childhood as an opportunity to prevent a known association in adults between poverty and the metabolic syndrome. The study is one of the first to characterize the timing of exposure to such stress and the emergence of the physiologic changes leading to cardio-metabolic disease and to document these relationships during this critical developmental period.

Bioengineers introduce CORDA algorithm to find new therapeutic targets for cancer

Rice University bioengineers have introduced a fast computational method to model tissue-specific metabolic pathways. Their algorithm may help researchers find new therapeutic targets for cancer and other diseases.

Practicing movements at different speeds enhances certain nerve functions after stroke or spine injury

Changes in one circuit of nerves, but not another, in the spinal cord depend on how quickly muscles must move to complete a task, according to results from the Human Motor Control Laboratory of Professor Kozo Funase, PhD, at Hiroshima University. The results could influence physical therapy routines for patients struggling to control their bodies after a stroke or spine injury.

New, regenerative medicine approach developed to remove congenital cataracts in infants

Researchers at University of California, San Diego School of Medicine and Shiley Eye Institute, with colleagues in China, have developed a new, regenerative medicine approach to remove congenital cataracts in infants, permitting remaining stem cells to regrow functional lenses.

TSRI researchers uncover new molecular mechanism underlying neurodegenerative diseases

A new study led by scientists at The Scripps Research Institute suggests that cells construct protein "clumps" to protect against neurodegenerative diseases such as amyotrophic lateral sclerosis, a.k.a. ALS or Lou Gehrig's disease.

Vanderbilt investigators isolate human antibodies against H7 bird flu

Researchers at Vanderbilt University Medical Center have isolated human antibodies against a type of bird flu that has killed more than 200 people in China since 2012 and which may pose a worldwide pandemic threat.

Scientists demonstrate method for generating eye tissues to restore lost or damaged vision

Scientists have demonstrated a method for generating several key types of eye tissue from human stem cells in a way that mirrors whole eye development.

Study reveals direct regulatory role of serotonin in rheumatoid arthritis

For the first time, serotonin (5-hydroxytryptamine, 5-HT) has been directly implicated in the pathophysiology of rheumatoid arthritis (RA). Although 5-HT is predominantly known as a neurotransmitter within the central nervous system, new evidence points to additional important functions for serotonin in the periphery.

Discovery may provide potential target for new therapies to treat bipolar disorder

Bipolar disorder, which affects nearly eight million Americans, takes a toll not only on patients, but also on their families and communities.

MGH researchers identify how Shigella injects proteins into target host cells

Researchers from the Massachusetts General Hospital Division of Infectious Diseases are investigating the mechanism by which several important pathogenic species of bacteria deliver proteins into the cells of the organisms they are infecting.

HIV-positive individuals in Africa with certain genetic variant have lower chance of developing TB

In the first known discovery of its kind, a Case Western Reserve University School of Medicine-led team has found that HIV patients in Africa with a certain genetic variant have a 63-percent lower chance of developing tuberculosis than HIV patients without the genetic variant.

New vaccine delays effects of nicotine within first 10 minutes after injection

Many people who smoke want to quit, but the urge to light up is often irresistible. An effective vaccine to help people kick the habit once and for all has been elusive. But now, scientists report in ACS' Journal of Medicinal Chemistry a new vaccine design that could help achieve this goal.

Scientists discover brain mechanisms that separate food consumption from cravings

Researchers investigating eating disorders often study chemical and neurological functions in the brain to discover clues to overeating. Understanding non-homeostatic eating -- or eating that is driven more by palatability, habit and food cues -- and how it works in the brain may help neuroscientists determine how to control cravings, maintain healthier weights and promote healthier lifestyles. Scientists at the University of Missouri recently discovered the chemical circuits and mechanisms in the brain that separate food consumption from cravings. Knowing more about these mechanisms could help researchers develop drugs that reduce overeating.

Novel nanoparticle technology can decipher protein structures and help access drug targets

Researchers at Karolinska Institutet, Sweden, have developed a nanoparticle technology that can be used to stabilise membrane proteins so that their structure can be studied in a lipid environment. The method, described in Nature Methods, makes it possible to access drug targets that previously could not be investigated and therefore potentially allows for the development of novel drugs, therapeutic antibodies and vaccines.

Hematopoietic reprogramming can lead to differentiated blood products for cell-replacement therapy

Building upon previous work, researchers at the Icahn School of Medicine at Mount Sinai identified cells in the embryos of mice that are precursors to blood stem cells or hematopoietic stem/progenitor cells.

Clinical review examines benefit of RT in breast cancer patients with BRCA1, BRCA2 mutations

In light of conflicting and inconclusive clinical data on the benefit of radiation therapy in cancer patients with the BRCA1 and BRCA2 mutation, a clinical review examined the current status of data regarding BRCA1 and BRCA2 deficiency and radiation therapy sensitivity and a potential strategy to intensify the effects of radiation therapy (RT) by poly(ADP-ribose) polymerase inhibitors (PARPi), the pharmacologic drugs under investigation as monotherapy for the treatment of breast cancer in patients with BRCA1 and BRCA2 mutations.

Startling lack of resistance genes discovered in intensively-farmed beef

In the first study to track antibiotic resistance in intensively-farmed beef, scientists discovered a "startling" lack of resistance genes in meat.Meanwhile, in soil and faeces samples from cattle pens they found genes resistant to a powerful "last resort" class of antibiotics called carpabemens that aren't used in the livestock industry. These genes may have jumped from humans or companion animals to livestock, or could even be present at low levels in the wider environment.

Genetically engineered mexican lime contains anthocyanins that has several potential benefits

Anthocyanins, pigments that give plants their red, blue, or purple hues, are not typically produced in citrus fruits grown under tropical or subtropical conditions. Now, scientists have genetically engineered a lime that contains anthocyanins, which they say has several potential benefits.
