Drastic population collapse in Central Africa was caused by prolonged disease epidemic, indicates study

A new study published in the journal Science Advances shows that Bantu-speaking communities in the Congo rainforest underwent a major population collapse from 1600 to 1400 years ago, probably due to a prolonged disease epidemic, and that significant resettlement did not restart until around 1000 years ago.

Virus transmission by dental tools and prevention by antiviral agent

Researchers at the University of Ljubljana have demonstrated how a virus can spread by droplets during ultrasonic scaler (USS) operation and how this spread can be mitigated by merely substituting the irrigant with clinical virucidal agents, namely sodium hypochlorite and EOW (Electrolyzed Oxidizing Water).

Changes to gut microbiome help melanoma patients respond to immunotherapy

Statistical modeling developed by Oregon State University researchers has confirmed that changes to melanoma patients' gut microbiome led them to respond to a type of treatment capable of providing long-term benefit.

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.

Researchers create new cancer optotheranostics based on photosynthetic bacteria

Cancer is one of the most thought-provoking healthcare problems throughout the world. The development of therapeutic agents with highly selective anti-cancer activities is increasingly attractive due to the lack of tumor selectivity of conventional treatments.

Research shows how chemicals in the tumor microenvironment enable cancer to evade attack

A paper published today in Nature shows how chemicals in the areas surrounding tumors--known as the tumor microenvironment--subvert the immune system and enable cancer to evade attack. These findings suggest that an existing drug could boost cancer immunotherapy.

Study: Gut microbiota impacts the progression of brain lesions after stroke

Stroke-induced inflammation is both a blessing and a curse. Some of the inflammatory processes help heal the damaged brain after treatment, but others severely damage neurons and whole-body function.

Vaccine candidate containing tetanus toxoid potentially protective against SARS-CoV-2

Researchers from Cuba, China, and France have demonstrated the potential of coupling a viral antigen with the tetanus toxoid protein as a vaccination approach to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent that causes coronavirus disease 2019 (COVID-19).

Using a smartphone-based microscope for detecting single molecules and diagnosing diseases

Biomarkers play a central role in the diagnosis of disease and assessment of its course. Among the markers now in use are genes, proteins, hormones, lipids and other classes of molecules.

Single strain of bacteria may reduce the severity of graft-versus-host disease

MUSC Hollings Cancer Center researchers found that a single strain of bacteria may be able to reduce the severity of graft-versus-host disease (GVHD), as reported online in February 2021 in JCI Insight.

Seagulls could act as sentinels of the antibiotic pressure in the environment

Gulls are one of the main wild birds that act as reservoirs of Campylobacter and Salmonella, two most relevant intestinal antibiotic-resistant bacteria causing gastroenteritis in humans.

Chocolate-flavored e-cigarettes are 'particularly harmful' to the lungs, study shows

New research shows chocolate-flavored e-cigarettes are "particularly harmful" to the lungs. In fact, scientists found all 10 flavors tested caused some level of toxicity in the cells lining the lungs, resulting in cell death in some instances.

Researchers develop new weapon to fight against resistant bacteria

Every day, people die from simple infections even though they have been treated with antibiotics. This is because more and more bacteria have become resistant to the types of antibiotics that doctors can prescribe.
