The ability of antibodies to recognize specific cancer cells is used in oncology to specifically target those cells with small active agents. Research published in the journal Angewandte Chemie shows that scientists have now built a transport system that delivers even large protein-based drugs into cancer cells. This study demonstrates how proteins can arrive at…
Asthma attacks account for almost 50 percent of the cost of asthma care which totals $80 billion each year in the United States. Asthma is more severe in Black and Hispanic/Latinx patients, with double the rates of attacks and hospitalizations as the general population. When the COVID-19 pandemic swept over the United States, a series…
Just as people keep their houses clean and clutter under control, a crew of cells in the body is in charge of clearing the waste the body generates, including dying cells. The housekeeping cells remove unwanted material by a process called phagocytosis, which literally means ‘eating cells.’ The housekeepers engulf and ingest the dying cells…
The second new study, which was published in The Lancet, was conducted by researchers at the Israel Ministry of Health and Pfizer. It is based on more than 230,000 coronavirus infections that occurred in Israel between Jan. 24 and April 3. During that period, B.1.1.7 accounted for nearly 95 percent of all coronavirus cases in…
Of all the imaging equipment, the only one generally unsuitable for the operating room is that needed for magnetic resonance imaging — commonly known as an M.R.I. — because of its size. As a result, Ms. Saba said, some hospitals essentially are stationing them adjacent to an operating room in case an M.R.I. is needed.…
In early 2020, dozens of scientific teams scrambled to make a vaccine for Covid-19. Some chose tried-and-true techniques, such as making vaccines from killed viruses. But a handful of companies bet on a riskier method, one that had never produced a licensed vaccine: deploying a genetic molecule called RNA. The bet paid off. The first…
Their nerves seemed especially sensitive to the buildup of certain substances in the working muscles, the researchers concluded, which prompted the nerves to send urgent messages to nearby blood vessels, ordering them to contract. The result was lingering high blood pressure, during and after the workout. These reactions were most marked among the rheumatoid arthritis…
WHAT: A team of researchers funded by the National Institutes of Health has developed a new ultrasound technique to monitor the placenta for impaired fetal blood flow early in pregnancy. The technique, which uses conventional ultrasound equipment, relies on subtle differences in the pulsation of fetal blood through the arteries at the fetal and placental…
Researchers from the University of Liverpool have shown the potential of repurposing an existing and cheap drug into a long-acting injectable therapy that could be used to treat Covid-19. In a paper published in the journal Nanoscale, researchers from the University’s Centre of Excellence for Long-acting Therapeutics (CELT) demonstrate the nanoparticle formulation of niclosamide, a…
A new service piloted at Penn Medicine allowed a proportion of patients to avoid hospitalization by providing them with greater support after visiting the emergency department. The vast majority of the patients enrolled in the service – nearly 9 out of 10 – did not need to return to the hospital for care in the…
