pH News and Research

RSS

pH comes from the term “power of Hydrogen”, or the hydrogen ion concentration present in a given solution. It helps to measure the acidity or alkalinity of a substance.

New class of smart prosthetic implants may help prevent blindness

Blindness in millions of people with diseases that starve eye tissue and nerves of oxygen might be averted with a procedure being developed by researchers at Oak Ridge National Laboratory, the University of Southern California and the University of Tennessee.

MannKind Corporation submits NDA for Afresa for treatment of diabetes

MannKind Corporation has announced that it has submitted a New Drug Application (NDA) to the U.S. Food and Drug Administration (FDA) requesting approval of Afresa (insulin monomer human [rDNA origin]) Inhalation Powder and the Afresa Inhaler for the treatment of adults with type 1 or type 2 diabetes mellitus for the control of hyperglycemia.

Vitamin C intake linked to lower risk of gout in men

Men with higher vitamin C intake appear less likely to develop gout, a painful type of arthritis, according to a report in the March 9 issue of Archives of Internal Medicine, one of the JAMA/Archives journals.

Discovery of alga that detoxifies arsenic

Arsenic may be tough, but scientists have found a Yellowstone National Park alga that's tougher.

Spun-sugar filaments show potential for regenerating nerves

Researchers at Purdue University have developed a technique using spun-sugar filaments to create a scaffold of tiny synthetic tubes that might serve as conduits to regenerate nerves severed in accidents or blood vessels damaged by disease.

Microfluidic device mimics tumor microenvironment, helps drug discovery

One of the challenges that cancer researchers face in designing new antitumor agents is that of predicting how drug molecules will behave in the complex microenvironment that surrounds a tumor. In particular, tumors create all sorts of chemical and physical barriers that limit how much drug is able to enter a tumor, let alone reach cells deep within a tumor.

Quantum dot hazards

Quantum dots have the potential to bring many good things into the world: efficient solar power, targeted gene and drug delivery, solid-state lighting and advances in biomedical imaging among them.

HPV18 DNA levels are not prognostic for precancerous cervical lesions

Perhaps surprisingly, the number of copies of the carcinogenic human papillomavirus type 18 (HPV18) relative to cellular DNA is not associated with the likelihood of progression to advanced precancerous lesions of the cervix, according to a study in the January 27 online issue of the Journal of the National Cancer Institute.

New nano-insulin pill could replace injections for diabetics

Indian scientists suggest that people currently controlling their diabetes with daily insulin injections will soon be able to use an insulin pill instead.

Reasons behind the South's higher stroke death rate

Southerners die from stroke more than in any other U.S. region, but exactly why that happens is unknown.

Repeat cesarean deliveries before 39 weeks raises risk of neonatal illness

Women choosing repeat cesarean deliveries and having them at term but before completing 39 weeks gestation are up to two times more likely to have a baby with serious complications including respiratory distress resulting in mechanical ventilation and NICU admission.

Targeted nanoparticles deliver therapeutic DNA to cancer cells

Given that cancer is a disease caused by gene mutations, cancer researchers have been striving to develop gene therapies aimed at correcting these mutations. However, these efforts have been hobbled by the difficulty in safely and efficiently delivering anticancer genes to tumors. Nanoparticles, however, may solve these delivery issues, and two recently published studies, using two different types of nanoparticles, lend credence to that hypothesis.

Partnerships take aim at improving children's asthma

Asthma is one the main causes of pediatric hospital admissions, both nationally and locally. Last year, there were 900 asthma-related visits to the Pediatric Emergency Department at Golisano Children's Hospital. Golisano Children's Hospital at Strong is working to lower that number.

New understanding of RNA and evolution

With the aid of a straightforward experiment, researchers have provided some clues to one of biology's most complex questions: how ancient organic molecules came together to form the basis of life.

Key survival circuit discovered in Salmonella bacteria

Hundreds of trillions of bacteria make their home in the vertebrate gut. Though many of these microbes perform helpful duties for their host, others - the pathogens - are unwelcome visitors, causing disease.

New anti-tumor gene called SARI

Researchers from Virginia Commonwealth University have identified a new anti-tumor gene called SARI that can interact with and suppress a key protein that is overexpressed in 90 percent of human cancers.

Still wide racial disparities in colorectal cancer rates

An American Cancer Society reports says despite unprecedented progress in reducing incidence and death rates from colorectal cancer, the gap between blacks and whites continues to grow.

Lupin allergy in children

During her doctoral work, Lise Holden developed a method of identifying lupin protein in food products. She also investigated the incidence of lupin allergy among children with food allergy and studied the proteins in lupin responsible for allergy production.
