Research demonstrates within-host seasonal immunity

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus responsible for coronavirus disease 19 (COVID-19), first emerged in Wuhan, China in late December 2019, before spreading to the rest of the world. Many governments were forced to enact costly and restrictive measures in an attempt to reduce the rapid transmission of SARS-CoV-2, from mandatory

Irradiation of tumors with laser protons tested for the first time

Irradiation with fast protons is a more effective and less invasive cancer treatment than X-rays. However, modern proton therapy requires large particle accelerators, which has experts investigating alternative accelerator concepts, such as laser systems to accelerate protons. Such systems are deployed in preclinical studies to pave the way for optimal radiation therapy. A research team

PrEP Kidney Function Monitoring to Be Fine-Tuned

NEW YORK (Reuters Health) – The risk of kidney-related adverse events among patients receiving tenofovir disoproxil fumarate (TDF)-based oral HIV pre-exposure prophylaxis (PrEP) is small, a systematic review and meta-analysis revealed. Therefore, less frequent monitoring may be appropriate for some younger people, Dr Robin Schaefer of the World Health Organization (WHO) in Geneva and colleagues

Implementing wastewater-based Covid-19 early warning system in Germany

Coronaviruses can be detected in wastewater some days before first disease symptoms develop. On this basis, it is possible to determine the number of infections more quickly, analyze the infection situation more precisely, and identify new Covid-19 variants and their spread at an earlier stage. The project "Systematic Monitoring of SARS-CoV-2 in Wastewater" coordinated by

Novel targets to inhibit SARS-CoV-2 variants

A recent study published in the journal Viruses identified additional targets on severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) proteins to prevent the emergence of new SARS-CoV-2 variants of concern (VOCs).  Study: Conserved Targets to Prevent Emerging Coronaviruses.

Poland Sees Signs Women Fleeing Ukraine May Be Trafficking Target

PRZEMYSL, Poland (Reuters) – Poland has seen indications that human traffickers may be targeting refugees fleeing the Ukraine war, officials and aid workers said on Tuesday, and although trafficking cases have not been confirmed, preventative efforts are now being put in place. Nearly two million people, mostly women and children, have arrived in Poland since

6 healthy steps to preventing colon cancer

Colon cancer can be a devastating diagnosis, but there are a number of steps you can take to reduce your risk of tumors, an expert says. Colorectal cancer is the third-leading cause of cancer in the United States, and the American Cancer Society estimates that 106,180 cases of colon cancer and 44,850 cases of rectal

Microbes and Nutrient Cycling

A nutrient cycle refers to the exchange of organic and inorganic matter throughout an ecosystem, causing particular substances and elements to be sequestered, removed, recycled, and generated in the environment. Microbial life has long been known to play a vital role in the consumption and regeneration of resources in the environment at many levels and

Aspirin fails to inhibit breast cancer recurrence

Aspirin use failed to reduce recurrence rates among women with breast cancer in a phase 3, randomized, controlled trial that was halted following a planned futility analysis. The aspirin group actually had greater risk of recurrence, though the result did not reach statistical significance. Aspirin has proven effective in reducing recurrence rates in colon cancer. Despite

UH researchers receive grant for developing new imaging technique to peer into ribosomes

Two University of Houston researchers are developing a type of spectroscopy to help understand how ribosomes make proteins deep within cells, the discovery of which could potentially guide drug design to treat cancers and viral infections. Spectroscopy measures the interaction between light and matter to determine characteristics and volume of cellular matter. In cellular biology,
