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 study shows how tumor cells evade the immune system

If cancer is a series of puzzles, a new study pieces together how several of those puzzles connect to form a bigger picture.

Ocean acidification is affecting the world’s tropical reefs

The scaffolds that help hold together the world's tropical reefs are at risk from acidification due to increased carbon dioxide in the world's oceans, according to geoscientists at the University of Sydney.

Metastatic cancer cells reshape, destroy or integrate into blood vessels

In laboratory studies, Johns Hopkins Kimmel Cancer Center and Johns Hopkins University researchers observed a key step in how cancer cells may spread from a primary tumor to a distant site within the body, a process known as metastasis.

Researchers aim to convert greenhouse gas emissions into fuels

Shaama Sharada calls carbon dioxide -- the worst offender of global warming -- a very stable, "very happy molecule."

New cellular pathway can protect cells from infection by Ebola virus, coronavirus

Discoveries from the Benaroya Research Institute at Virginia Mason (BRI) have identified a new cellular protection pathway that targets a common vulnerability in several different pandemic viruses, and collaborators at Case Western Reserve University, Boston University School of Medicine and MRIGlobal have shown that this pathway can protect cells from infection by Ebola virus and coronaviruses, like SARS-CoV-2.

First lethal mouse model established for COVID-19 infection

Army scientists have developed the first lethal mouse model of SARS-CoV-2, the virus that causes COVID-19, using mice that were genetically engineered to express the human ACE2 gene--a key mechanism by which the virus enters human cells.

Scientists identify antigen valencies that work best in vaccine designs for HIV, SARS-CoV-2

Designing a vaccine starts with finding the right ingredients. Every infectious agent has molecules, called antigens, that the immune system could potentially recognize and attack. So scientists must carefully consider which antigens should go into a vaccine.

Botanical gardens are uniquely positioned to advance plant conservation

The world is experiencing a sixth global mass extinction event, and a new paper advocates that botanical gardens are uniquely positioned to preserve the world's plant diversity.

STING protein activates a pathway that kills tumor-fighting immune cells

The immune protein STING has long been noted for helping protect against viruses and tumors by signaling a well-known immune molecule. Now, UT Southwestern scientists have revealed that STING also activates a separate pathway, one that directly kills tumor-fighting immune cells.

Environmental and ecological uncertainty favors the evolution of bet-hedging

Some birds lay their eggs in the nests of other bird species and let the host parents raise their young. A new study finds that in times of environmental flux, these brood parasites "diversify their portfolios," minimizing the risks of their unorthodox lifestyle by increasing the number and variety of hosts they select as adoptive parents.

Study examines the impact of low-carb, high-fat diet in older people

A new study, published in Nutrition and Metabolism, from researchers with the University of Alabama at Birmingham's Nutrition Obesity Research Center observed improvements in body composition, fat distribution and metabolic health in response to an eight-week, very low-carbohydrate diet.

Small set of genes may help decide the identity of every neuron in worms

When it comes to brain cells, one size does not fit all. Neurons come in a wide variety of shapes, sizes, and contain different types of brain chemicals.

Greater gut microbial diversity in kidney cancer patients linked to better treatment outcomes

Physicians at City of Hope, working in collaboration with scientists at Translational Genomics Research Institute (TGen), have found that greater gut microbial diversity in patients with metastatic kidney cancer is associated with better treatment outcomes on Food and Drug Administration-approved immunotherapy regimens.

Shielded stem cells can improve heart healing

Ghanta, R.K., et al. (2020) Immune-modulatory alginate protects mesenchymal stem cells for sustained delivery of reparative factors to ischemic myocardium. Biomaterials Science. doi.org/10.1039/D0BM00855A.

LJI scientists tracked down rare stem cells that generate neutrophils in humans

Neutrophils are the warriors of the immune system. They are always ready to spring to action to help heal injuries or fight off disease. Unless, that is, something goes wrong in their developmental process.

Researchers discover the exit route for Vibrio bacteria from cells

As soon as the foodborne pathogen Vibrio parahaemolyticus infects a human intestinal cell, the bacteria are already planning their escape. After all, once it is in and multiplies, the bacterium must find a way out to infect new cells.

Drugs designed to lower alpha-ketoglutarate levels could help fight DIPG tumors

Every year, 150 to 300 children in the United States are diagnosed with diffuse intrinsic pontine gliomas (DIPGs), aggressive and lethal tumors that grow deep inside the brain, for which there are no cures.

High-speed AFM enables real-time visualization of influenza A hemagglutinin during viral entry

Unlike living organisms, to avoid extinction, viruses need to hijack living host machineries to generate new viruses.

Extrachromosomal DNA with potential to cause cancer drives poor patient outcomes

The multiplication of genes located in extrachromosomal DNA that have the potential to cause cancer drives poor patient outcomes across many cancer types, according to a Nature Genetics study published Aug. 17, 2020 by a team of researchers including Professors Vineet Bafna and Dr.Paul Mischel of the University of California San Diego and Professor Roel Verhaak of Jackson Laboratories.
