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.

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.

An integrated approach could pave the way for future control of Alzheimer's disease

This new pioneering study by Prof. Ricardo Maccioni and coworkers of the International Center for Biomedicine, "New Frontiers in the prevention, diagnosis and treatment of Alzheimer´s disease" was published in the special issue of Latin American investigators of the Journal of Alzheimer's Disease.

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.

Second-generation double antibody protects from SARS-CoV-2 and its tested variants

The Institute for Research in Biomedicine (IRB; Bellinzona, Switzerland), affiliated to the Università della Svizzera italiana (USI) developed a second-generation 'double antibody' that protects from SARS-CoV-2, the virus causing COVID-19, and all its tested variants. It also prevents the virus from mutating to resist the therapy.
