New book provides insight into the pathophysiology of leprosy

Leprosy remains one of the biggest public health problems in many countries. It is a complex disease in several aspects, including clinical, histopathological, and molecular.

Incorrect DNA packaging makes retrotransposons more accessible

Scientists led by Dr. Salvador Aznar-Benitah, head of the Stem Cells and Cancer laboratory at IRB Barcelona, have described the alterations that occur during mammary gland formation when heterochromatin (the part of DNA that does not actively produce proteins) is poorly regulated.

Study shows possible link between intestinal polyps in close relatives and colorectal cancer risk

Cancer of the colon and rectum is one of the deadliest forms of cancer, and has in recent years affected growing numbers of young people.

Novel method provides faster and more precise diagnostics in histopathology

Histology is the study of biological tissues at a microscopic level. Also called microscopic anatomy, histology is widely used to provide diagnosis of cancer and other diseases.

Study aims to advance breast cancer detection methodologies through spectroscopic imaging

Detecting and analyzing breast cancer goes beyond the initial discovery of the cancer itself. If a patient has a tumor removed and it needs to be analyzed to determine further treatment, it might be OK for the results to take 24 hours.

Mouse monoclonal antibodies protect against SARS-CoV-2 wildtype, UK and South African variants

A new preprint research paper posted to the bioRxiv server reports on the ability of a set of neutralizing mouse antibodies to protect mice against multiple lineages of SARS-CoV-2.

New nanoparticle SARS-CoV-2 vaccine confers robust protection with single dose after two weeks

In a methodologically ‘state-of-the-art’ approach, US researchers have developed a protein-based nanoparticle vaccine against coronavirus disease (COVID-19), with a swift generation of antibodies and the potential to protect individuals who cannot receive other COVID-19 vaccines for medical reasons. The research is posted to the bioRxiv* preprint server.

Novel protein construct prevents lethal COVID-19 in mice

Researchers in the United States have developed a novel protein that prevented lethal disease among mice infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent that causes coronavirus disease 2019 (COVID-19).

Xenograft model for invasive lobular carcinoma simulates tumor with high accuracy

Invasive lobular carcinoma (ILC) is a type of breast cancer that begins in the milk-producing glands (lobules) of the breast.

Study maps SARS-CoV-2 infected brains

Researchers in the United States and Canada have mapped the presence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in the brains of people who died from coronavirus disease 2019 (COVID-19).

Study provides new information about the structure of prion proteins

Prion diseases are a group of rapidly progressive, fatal and infectious neurodegenerative disorders affecting both humans and animals: Bovine Spongiform Encephalopathy (BSE) or 'mad cow' disease is one of the most famous since in 1996 scientists found that the agent responsible for the disease in cows, is the same agent responsible for the so-called variant Creutzfeldt-Jakob Disease (vCJD), a disease affecting humans.

Elevated ACE2 and inflammation levels increase risk for pregnant women infected with SARS-CoV-2

Among the hundred million or so cases of coronavirus disease 2019 (COVID-19) that have occurred since the pandemic began, pregnant women have been a conspicuous risk group. However, the exact nature of the risk they and their fetuses face, and the mechanism by which it operates, is far from clear.

Study supports continuing phase 3 trials of Ad26.COV2.S SARS-CoV-2 vaccine

An international team of researchers has provided further evidence to confirm the immunogenicity and efficacy of a recombinant adenovirus vaccine currently being tested in phase 3 trials for its ability to protect against infection with severe acute respiratory coronavirus 2 (SARS-CoV-2) – the agent that causes coronavirus disease 2019 (COVID-19).

Study shows an inflammatory response in the mice brain is responsible for severe COVID-19

Researchers demonstrated that neuroinvasion and encephalitis caused by SARS-CoV-2 is associated with significant mortality in a special mouse model.

State-of-the-art technology provides high levels of accuracy in breast cancer diagnosis

State-of-the-art technology which helps doctors more accurately diagnose breast cancer has been hailed as a breakthrough by the US Food & Drugs Administration (FDA) for its exceptional potential clinical value in improving patient care.

Researchers monitor effects of COVID-19 outbreak on care of cancer patients

Fewer breast and colorectal cancer diagnoses have been made in the Netherlands due to the COVID-19 crisis this spring. The decline in the number of diagnoses was more abundant in age groups invited to national population screening programmes, as compared to other age groups.

Even mild fatty liver disease associated with higher risk of all-cause mortality

Non-alcoholic fatty liver disease, NAFLD, affects nearly one in four adults in Europe and the U.S. Earlier research has demonstrated an increased risk of death in patients with NAFLD and advanced fibrosis or cirrhosis.

Researchers examine the cooperative effects of genes in suppressing neuroendocrine tumors in mice

Volume 11, Issue 28 of Oncotarget features "Genetic analysis of the cooperative tumorigenic effects of targeted deletions of tumor suppressors Rb1, Trp53, Men1, and Pten in neuroendocrine tumors in mice" by Xu et, al. which reported that the authors examined whether the TSGs Rb1, Trp53, Pten, and Men1 have cooperative effects in suppressing neuroendocrine tumors in mice.

Cerenkov luminescence imaging can accurately assess surgical margins during radical prostatectomy

A new intraoperative imaging technique, Cerenkov luminescence imaging (CLI), can accurately assess surgical margins during radical prostatectomy, according to a first-in-human research published in the October issue of the Journal of Nuclear Medicine.

HIV drugs cause immune-system changes that can improve resistance to viral infections

Drugs currently used to keep the HIV virus in check also cause immune-system changes that might make humans better able to resist viral infections – but might also cause harmful inflammation, according to a study published today in Cell Reports Medicine.
