Role of SARS-CoV-2 infection biomarkers in HIV replication

Mon, 10/25/2021 - 15:01
A new study investigates the role of the S100A8/A9 complex in the replication of HIV.

Blood pressure drug increases SARS-CoV-2 receptors in transmission and pathogenesis associated tissues

Mon, 10/25/2021 - 14:36
A new study aimed to determine whether ACE2 targeting drugs change the tissue levels of ACE2 in healthy mice.

Study suggests seropositive individuals produce anti-SARS-CoV-2 antibodies with improved potency and breadth

Mon, 10/25/2021 - 13:56
Researchers isolated single cells among individuals with and without prior infection with the SARS-CoV-2 vaccinated with BNT162b2 mRNA vaccine and compared the nature of the neutralizing antibody response against the original Wuhan virus and the subsequent variants.

Men with Stage IV breast cancer who are receptive to systemic therapy benefit from surgery

Mon, 10/25/2021 - 13:17
Men with Stage IV breast cancer and known estrogen (ER) and progesterone receptor (PR) status benefit from surgical intervention and from trimodal therapy (systemic therapy, surgery, and radiation), according to a study presented at the virtual American College of Surgeons (ACS) Clinical Congress 2021.

Nanoparticle-mediated, slow-release delivery of TT-10 enhances heart attack recovery in mouse model

Mon, 10/25/2021 - 12:51
A heart attack kills heart muscle cells, leading to a scar that weakens the heart, often leading to eventual heart failure. The lack of muscle repair is due to the very limited ability of mammalian heart muscle cells to proliferate, except for a brief period around birth.

Many long-term survivors of childhood cancer may face elevated suicide risk

Mon, 10/25/2021 - 12:32
Survivors of childhood cancer have increased risks of experiencing various challenges, such as emotional distress, impaired quality of life, and financial burdens.

Telemedicine approach remains a viable alternative for lung cancer screening

Mon, 10/25/2021 - 12:24
A novel telemedicine lung cancer screening effort during the COVID-19 pandemic shows that virtual single-visit screenings are just as effective as single-visit screenings done in person at the hospital, according to a study presented at the American College of Surgeons Virtual Clinical Congress 2021.

Decreasing length of hospitalization increases post-discharge complications for surgical patients

Mon, 10/25/2021 - 12:07
New study results suggest the national trend toward decreasing length of hospitalization after surgical procedures may come at the expense of an increasing proportion of complications occurring after patients leave the hospital.

SARS-CoV-2 Delta variant transmitted by fully vaccinated individuals in Provincetown, Massachusetts

Mon, 10/25/2021 - 11:41
A new study, posted to the medRxiv* preprint server, describes the genomic epidemiology of this outbreak. It provides a deeper understanding of viral transmission from and between fully vaccinated individuals.

Scientists show how cold could alleviate multiple sclerosis symptoms

Mon, 10/25/2021 - 11:35
In evolutionary biology, the "Life History Theory", first proposed in the 1950s, postulates that when the environment is favorable, the resources used by any organism are devoted for growth and reproduction.

How COVID-19 affects household food security

Mon, 10/25/2021 - 11:19
A new study published on the bioRxiv* preprint server investigates changes in household food insecurity throughout the first year of the COVID-19 pandemic. To do this, researchers followed a cohort of Vermonters and examined the socio-demographic characteristics correlated with increased odds of experiencing food insecurity.

Mon, 10/25/2021 - 11:01
A new study posted to the medRxiv* preprint server studies the neutralizing antibody response in cancer patients diagnosed with chronic lymphocytic leukemia (CLL), lung cancer, breast cancer, and various non-Hodgkin’s lymphomas (NHL), post-reception of two doses of messenger RNA (mRNA) vaccines.

Mon, 10/25/2021 - 10:51
Rutgers researchers have linked the genetic disorders Fragile X and SHANK3 deletion syndrome – both linked to autism and health problems – to walking patterns by examining the microscopic movements of those wearing motion-sensored sneakers.

Molecular mechanism that controls the transition from acute to chronic pain revealed

Mon, 10/25/2021 - 10:31
A new study led by University of California, Irvine researchers is the first to reveal the specific molecular mechanism that controls the transition from acute to chronic pain, and identifies this mechanism as a critical target for disease-modifying medicines.
