Each city has its own exclusive microbiome, finds study

A new study performed by researchers report that each city has its own exclusive microbiome or a “fingerprint” of bacteria and viruses that uniquely identify it.

Study discovers novel function for metabolic enzyme medium-chain acyl-CoA dehydrogenase

Scientists have come up with an innovative function for the metabolic enzyme medium-chain acyl-CoA dehydrogenase (MCAD) in glioblastoma (GBM).

New consortium of bacteria can be used to treat aggressive colitis in humanized mouse models

A new study reported in Nature Communications shows that a consortium of bacteria, developed to complement lacking or poorly represented functions in the imbalanced microbiome of inflammatory bowel disease (IBD) patients, inhibited and treated chronic immune-mediated colitis in humanized mouse models.

Researchers explore new ways to culture living heart cells for microgravity research

As part of preparing for an experiment aboard the International Space Station, researchers explored new ways to culture living heart cells for microgravity research. They found that cryopreservation, a process of storing cells at -80°C, makes it easier to transport these cells to the orbiting lab, providing more flexibility in launch and operations schedules.

New microscope helps observe the whole body of the embryo

A research group led by Takashi Saito, of the Ehime University Graduate School of Medicine, developed a 2-photon excitation light-sheet fluorescence microscope which (1) lowers phototoxicity, (2) extends the field of view, and (3) heightens spatial resolution.

More informed choices of contraceptives can prevent breast cancer

Hormonal contraceptives, e.g. the pill, the patch, and the vaginal ring, contain synthetic hormones that prevent pregnancy by either stopping ovulation, changing the cervical mucus to stop sperm from passing through the cervix and finding an egg, or changing the womb's lining to prevent a fertilized egg from being implanted in it.

New study may help improve stem cell transplantation, lead to better drugs

Your immune system is always busy fighting incoming threats. It consists of a system of cells, and when there is a shortage of cells, it affects the performance of the immune system.

Novel drug is highly effective in preventing severe COVID-19 in mice

The drug diABZI -- which activates the body's innate immune response -- was highly effective in preventing severe COVID-19 in mice that were infected with SARS-CoV-2,

Scientists identify mechanism by which head and neck cancer cells subvert adjacent normal tissue

Up to half of patients with head and neck squamous cell carcinoma will experience tumor recurrence or new tumors--tumors that often spread and are difficult to treat.

New wiki promotes development of innovative saliva-based diagnostic tests and customized treatment

The NIDCR has funded the creation of the Human Salivary Proteome Wiki, the first public platform that organizes information on each of the proteins found in human saliva.

Immune system’s killer T cells make mistakes in distinguishing healthy from infectious cell

When it comes to differentiating between a healthy cell and an infectious cell that has to be killed, the immune system’s killer T cells might make mistakes.

Neutralizing antibodies are produced after SARS-CoV-2 infection

A research group from Osaka University led by Professor Hisashi Arase and consisting of researchers from the Research Institute for Microbial Diseases, the Institute for Protein Research, the Immunology Frontier Research Center, the Center for Infectious Diseases, and the Graduate School of Medicine has discovered for the first time that both neutralizing antibodies that protect against infection as well as infection-enhancing antibodies that increase infectivity are produced after infection with SARS-CoV-2 by analyzing antibodies derived from COVID-19 patients.

Study could help develop peptide siRNA carrier for human oral cancer

MUSC Hollings Cancer Center researchers are exploring the use of peptide carriers for the delivery of small RNA drugs as a novel treatment for cancer. The team's recent work, published online March 19 in the Molecular Therapy - Nucleic Acids journal, lays the foundation for developing a clinically relevant peptide carrier RNAi-based drug treatment strategy for human oral cancer.

“Paralyzed” immune cells can be reactivated by drugs in IDH-mutant gliomas

Brain tumor cells with a certain common mutation reprogram invading immune cells. This leads to the paralysis of the body's immune defense against the tumor in the brain. Researchers from Heidelberg, Mannheim, and Freiburg discovered this mechanism and at the same time identified a way of reactivating the paralyzed immune system to fight the tumor.

Telomere length decreases most rapidly from birth to age 3, shows study

Telomeres are protective caps on DNA that shorten as we grow older. Now, one of the first studies to examine telomere length (TL) in childhood finds that the initial setting of TL during prenatal development and in the first years of life may determine one's TL throughout childhood and potentially even into adulthood or older age.

Studies highlight different aspects of link between obesity and cancer

Multi-factorial metabolic and inflammatory abnormalities in obesity, independently or in combination, seems to be the critical biological link of obesity, cancer and racial/gender health disparities. However, the specific cross-talk between these factors remain elusive.

Human self-organizing cardiac organoids mimic the architecture of a heart chamber

Self-organizing heart organoids created at the Austrian Academy of Sciences’ Institute of Molecular Biotechnology (IMBA) are also efficient injury and in vitro congenital disease models. These “cardioids” have the potential to transform studies into cardiovascular diseases and heart malformations.

Researchers discover canine coronavirus in East Malaysia

Researchers have discovered a new coronavirus, found in a child with pneumonia in Malaysia in 2018, that appears to have jumped from dog to human.
