Scientists in a new paper detected spike protein in the bloodstream of people with long COVID two months after infection and COVID-19 vaccination, suggesting that spike protein may persist in the body much longer than previously predicted and does not remain at the injection site. The study, published Dec. 27 in the European Review for Medical and Pharmacological Sciences, found vaccine spike protein in two patients at least two months after receiving their second dose of a COVID-19 vaccine and viral spike protein in one subject who previously recovered from infection in a cohort of 81 patients with long COVID syndrome. Samples gathered from the unvaccinated control group were negative for spike protein. “This study, in agreement with other published investigations, demonstrates that both natural and vaccine spike protein may still be present in long-COVID patients, thus supporting the existence of a possible mechanism that causes the persistence of spike protein in the human body for much longer than predicted by early studies,” the authors wrote. Although U.S. regulatory agencies claim vaccinating against COVID-19 can reduce the risk of developing long-term COVID, some research suggests the condition may be caused by an immune overreaction to the spike protein in COVID-19 […]

Bali Pulendran, a professor of microbiology, immunology, and pathology at Stanford University, has researched a mystery unique to COVID-19 for two years. “For almost every infectious disease, the most vulnerable populations are at the extremes of age—the very young and the very old,” he once said. “But with COVID-19, the young are spared.” The picture surrounding this enigma is still incomplete, but answers are forthcoming. Children Are Different Children are not mini-adults. Depending on their age, they can have similar or very different responses to infectious diseases. In the case of COVID-19, children generally experience a milder form of the disease. “It’s an interesting question that no one has fully answered,” said Dr. Cody Meissner, a professor of paediatrics at Dartmouth College’s Geisel School of Medicine, in an interview with sources. “Several theories have been put forward to try and explain this.” The primary reason is that children have a faster innate immune system, often referred to as the first line of defence, compared to adults. This enables them to mount a robust defence against respiratory infections more quickly. Another explanation is that children are more susceptible to respiratory infections, and some of these prior infections may provide them with […]

An analysis of Vaccine Adverse Event Reporting System (VAERS) data indicates that the COVID-19 vaccines are “significantly” more deadly than the flu vaccine, according to Sen. Ron Johnson (R-Wis.). The review was conducted by the senator’s staff and involved a certain level of assumption given that no publicly available data exist regarding how many flu vaccine doses were administered in the United States over the past 10 years. Using the number of distributed doses to generate that figure, they found that the number of deaths per million doses of the COVID-19 vaccines (25.5) far exceeded those estimated for the flu vaccine (0.46). “Using the midpoint assumption that 70 percent of distributed flu vaccines were administered, the 25.5 deaths per million doses of the COVID-19 vaccine represents a 55-fold increase over the flu vaccine deaths per million doses,” Mr. Johnson wrote in a Dec. 21 letter to the heads of the Department of Health and Human Services, U.S. Food and Drug Administration, and Centers for Disease Control and Prevention. “This is a shocking difference and only adds to the growing evidence of safety signals that are screaming to be taken seriously,” he added. Mr. Johnson cited the study as part of a request […]

The JN.1 variant of COVID-19 has been detected in several cases in Oman, according to a senior official. The official, from the Ministry of Health, confirmed that most of these Covid patients had a mild infection and that all of them have recovered. “The Sultanate of Oman takes all necessary surveillance and prevention measures throughout the year. The global spread of the new variant of Covid-19 JN.1 does not pose a significant risk to public health,” the official added. The official also said that the JN.1 Covid-19 variant is an interesting mutant with mild symptoms. There is no increase in the rate of hospitalisation in intensive care or wards currently.

The Ministry of Health (MoH) has identified six most vulnerable groups that are recommended to take the developed coronavirus vaccine by booking an appointment through its Sehhaty application. The ministry recommended that pregnant women; those aged 50 years and above; health practitioners who deal directly with patients; those who have chronic immunosuppressive diseases, including active cancer, and those who have risk factors due to excessive obesity. According to the Public Health Authority (Weqaya), the developed Covid-19 vaccine is used to prevent complications from coronavirus, and its effectiveness includes prevention of the prevailing variants. It is available for those above 18 years of age, and it can be taken regardless of the number of doses taken in the past. Weqaya recommended the groups more vulnerable of infection to take the jab in order prevent or reduce complications of the disease.

Why do we age? It’s a simple question with a not-so-simple answer. But with the help of modern biotechnology, scientists have been able to slowly piece together the biochemical basis of this long-held mystery. Our cells are like tiny molecular factories, working to carry out all of the essential processes our bodies need to survive. However, like factories, the machinery in our cells gets worn out over time, which is what causes our cells to age. Our cellular machinery is split into different substations, called organelles. And, when it comes to aging, two organelles are particularly important: a) the mitochondria—the energy-producing powerhouses of the cell, and; b) the lysosomes—the cell’s internal garbage disposal station. During the energy-making process, mitochondria can produce dangerous waste products, which build up over time and damage our DNA. Lysosomes, meanwhile, contain a soup of digestive enzymes that breakdown worn-out cellular components. If the lysosomes themselves become damaged, these enzymes can leak out into the rest of the cell and cause havoc on the remaining healthy cellular components. Therefore, damage to either of these cellular stations has been associated with aging, cell death and many age-related diseases. Clearly, keeping these organelles in ship shape is essential for […]

The list of health benefits that come along with regular exercise may have grown with a new study uncovering a link between staying active and the size of parts of the brain responsible for memory and learning capabilities. The exercise doesn’t have to be overly intense or prolonged to have brain boosting effects, according to the experts behind the study. The team included researchers from the Pacific Neuroscience Institute Brain Health Center (PBHC) at Providence Saint John’s Health Center and Washington University in St. Louis. The study looked at magnetic resonance imaging ( MRI) brain scans of 10,125 people, finding those who said they regularly engaged in some kind of physical activity – like walking, running, or sports – had larger brain volumes in specific areas. Those areas included the ‘decision making’ frontal lobe and the hippocampus – a part of the brain that’s important in how memories are stored and handled. The study also measured the total volume of each brain’s gray matter, which helps the brain process information, the its connective white matter. “We found that even moderate levels of physical activity, such as taking fewer than 4,000 steps a day, can have a positive effect on brain health,” says psychiatrist and neuroscientist David Merrill from the PBHC. “This is much […]

There was good news for fans of weight loss drugs this weekend, when Novo Nordisk unveiled details from a closely watched study that supports the use of Wegovy, its blockbuster weight-loss drug, to cut the risk of death by 18% in a trial that the Danish pharmaceutical company hopes will convince more health systems and insurers to pay for the treatment. Novo Nordisk on Saturday said the heart protective benefits of its wildly popular Wegovy obesity treatment are due to more than weight loss alone, according to new data presented at a major medical meeting on Saturday. Early data from the Danish drugmaker’s Select trial released in August demonstrated that Wegovy, which has been shown to help patients lose an average of 15% of their weight, also reduced incidence of heart attack, stroke or death from heart disease by 20%. The full results from the study, presented at the American Heart Association annual scientific meeting in Philadelphia in front of a standing room only crowd and published in the New England Journal of Medicine, suggest the drug has other beneficial effects beyond the known health benefits from losing weight. The heart risk difference between patients who received Wegovy, known chemically […]
