Human noroviruses are the leading cause of acute gastroenteritis worldwide, a major global health problem for which there are no specific treatments or vaccines. Understanding the first phase of infection—the process the virus follows to invade cells—is a decisive step in the development of effective preventive and therapeutic strategies. A team led by researchers at Baylor College of Medicine is making strides in that direction.

For almost 140 years, the origin and behavior of an enigmatic cell type inside lymph nodes, called a tingible body macrophage, has remained a mystery. Now, for the first time, scientists at the Garvan Institute of Medical Research have tracked the cell’s lifecycle and function, with implications for our understanding of autoimmune disorders.

A pair of clinical statisticians at Children’s Hospital Los Angeles has found that abstinence reboot interventions promoted by some online groups can lead to mental health issues. In their paper published in the journal Sexualities, Nicole Prause and James Binnie describe the results of a survey-based study they conducted to learn more about the mental state of people who have participated in such interventions.

Dominique Tremblay and Élie Boghossian, plastic surgeons at Maisonneuve-Rosemont Hospital (MRH) and researchers at the the Université de Montréal Faculty of Medicine, have developed a new approach to nerve transfer that essentially consists of moving certain healthy nerves from eligible patients to an inactive nerve, in order to reanimate the muscles of their hands and arms that were no longer functioning. This was achieved in the case of a young quadriplegic patient of Drs. Tremblay and Boghossian, Ms. Jeanne Carrière, who regained the use of her arms and hands with this new surgical technique.

The human immune system is incredibly versatile. Among its most skilled multitaskers are T cells, known for their role in everything from fighting infection to reining in inflammation to killing nascent tumors.

Government should come out in the open and disclose the contract for the Ndola-Lusaka dual carriageway because as things stand, it is a crime scene of corruption and plunder, Economic Freedom Fighters (EFF) President Kasonde Mwenda has said.
Mr Mwenda it was clear that there were individuals in the new dawn administration that had interests in the contract because the logic was not making sense.
He = said just for US$577million, President Hakainde Hichilema had sold the profit making Ndola-Lusaka road where a foreign company that makes plastic bags would collect toll fees for 25 years and make approximately a profit of over US$4.5 billion.
“I want to challenge Government to disclose the contents of this deal because I feel it is a bad deal for Zambia and if we are not careful we might be losing millions,” he said.
He said by handover date in 2048 that road would be obsolete-finished with no commercial road even with maintenance lives for 25 years in Zambia without redoing it). The concession period should be revised down to 12 years.
Mr Mwenda said that once ushered into office his government would undo the contracts because they were criminal.
He said it was evident that they were individuals who had vested interest in the road contract and that they had no regard for the Zambian people.

New research by investigators at the University of Alabama at Birmingham supports the premise that inflammation is associated with Parkinson’s disease early in the disease’s progression. The findings, published online in Movement Disorders, support the conclusion that central inflammation is observed early in the disease process of Parkinson’s, is independent of treatment for the disease, and correlates with cognitive features and certain peripheral markers of inflammation.

Sarcopenia is the decline of skeletal muscle mass with age, leading to loss of muscle strength (to move objects, shake hands etc.) and performance (walking and making other routine movements effectively). It involves chronic inflammation and is associated with cognitive alterations, heart disease and respiratory disorders. In short, it affects the quality of life, reducing independence and increasing the risk of injury, falls and even death.

A World Health Organization official in Africa is urging more support to countries facing cholera outbreaks, saying the disease has the potential to “quickly explode” as rainfall persists in some areas.

Most adolescents and young adults have experienced bullying in some form, with about one-third of them experiencing cyberbullying, contributing to mental health concerns. Cyberbullying involves electronic communication such as texts, emails, online videos and social media, which has become increasingly problematic over the last few decades. Several reasons include the anonymity it allows, the fact that it is not as easily monitored, and that adolescents and young adults have easier access to devices.
