Scientists discover mechanism by which epithelial tumors cause maturation defects

Conducted on the fly Drosophila, the study shows that tumors caused by chromosomal instability delay entry into the adult phase.

An optimized process to isolate and purify magnetic nanoparticles

Magnetic nanoparticles biosynthesized by bacteria might soon play an important role in biomedicine and biotechnology. Researchers of the University of Bayreuth have now developed and optimized a process for the isolation and purification of these particles from bacterial cells.

Accumulation of fatty tissue in the neck predicts adiposity, heart problems

Researchers from the University of Granada warn that an accumulation of fatty tissue in the neck (both the double chin and the deeper deposits, located between muscles and around the cervical vertebrae) is a predictor of central and overall adiposity, cardiometabolic risk, and a pro-inflammatory profile in sedentary young adults.

People with ADHD and DBDs share genetic variants associated with risky behaviors

People with attention-deficit / hyperactivity disorder (ADHD) combined with disruptive behaviour disorders (DBDs) share about the 80% of genetic variants associated with aggressive and antisocial behaviors.

Scientists examine DNA repair pathways and their impact on cancer evolution

DNA repair pathways exist to correct molecular damage caused by internal and external factors. However, any damage to these pathways can result in the creation of tumors and specific types of cancers.

Multi-resistant bacteria continue to grow in hospital wastewater

Scientists from the University of Gothenburg, Sweden presents evidence that hospital wastewater, containing elevated levels of antibiotics, rapidly kills antibiotic-sensitive bacteria, while multi-resistant bacteria continue to grow.

Study describes mechanism that limits immunosupressive activity of tumor-associated macrophages

Tumor cells are able to avoid the attack of the immune system through several mechanisms. For instance, these can secrete factors that turn macrophages -cells in the immune system- into dual action agents that contribute to the tumor progress and will protect it from immune body defenses: these become, thus, the tumor-associated macrophages (TAMs).

Scientists decipher the molecular blueprint for important receptor

In order for a drug to be effective at the right places in the body, it helps if scientists can predict as accurately as possible how the molecules of that drug will interact with human cells.

Researchers detect traces of COVID-19 virus in sewage flowing from campus buildings

Although it is still challenging to prevent the transmission of COVID-19, researchers at the University of Miami are using all the strategies they can to fend off the spread.

Pancreatic β cells secrete miR-29 in response to high levels of free fatty acids

In a new study published in Journal of Extracellular Vesicles, Chen-Yu Zhang's group and Antonio Vidal-Puig's group at University of Cambridge report that pancreatic β cells secrete miR-29 family members (miR-29a, miR-29b and miR-29c) in response to high levels of free fatty acids (FFAs). These β cell-derived miR-29s are delivered to the liver, promoting insulin resistance and enhancing hepatic glucose output.

Compound isolated from Ophiura sarsii can be used as an affordable drug for photodynamic therapy

An unusual biologically active porphyrin compound was isolated from seabed dweller Ophiura sarsii. The substance might be used as an affordable light-sensitive drug for innovative photodynamic therapy and for targeted treatment of triple-negative breast cancer and some other cancers.

Novel hybrid device to boost research on metastatic process of breast cancer cells

European researchers are working on a novel hybrid device to better understand the metastatic process of cancer cells travelling from breast to bone and fast screen new drugs against it.

Researchers develop systems to detect an atypical fungus responsible for severe pneumonia

The group led by Dr. Enrique J. Calderón - "Clinical Epidemiology and Vascular Risk" at the Institute of Biomedicine of Seville - IBiS/University Hospitals Virgen del Rocío and Macarena/CSIC/University of Seville, also a member of CIBERESP, participated in a project with researchers from CIBER-BBN, in which they developed systems to detect Pneumocystis jirovecii, an atypical fungus responsible for very severe pneumonia in immunosuppressed patients.

Novel quantum sensor offers a new route to early diagnosis, preventive treatment

Oxygen is essential for human life, but within the body, certain biological environmental conditions can transform oxygen into aggressively reactive molecules called reactive oxygen species (ROS), which can damage DNA, RNA, and proteins.

RPS-12 protein overproduction appears to trigger breast cancer and other malignancies

Using the developing eye of the fruit fly as a test platform, researchers found that RPS-12 protein overproduction appears to trigger triple-negative breast cancer and possibly some other malignancies.

Scientists unravel how lipids distribute proteins within cells

An international team of scientists, coordinated by the Seville Institute of Biomedicine and the University of Seville has solved one of the hitherto unresolved enigmas of basic biology: how exactly do lipids distribute proteins within a cell? To do this, they used a new, completely innovative microscopy technology, which they applied to "mutant" cells they designed in their laboratory.
