UCSF scientists combine a precision drug therapy with an antibody and radiation to eliminate tumors without causing side effects.  Radiation is one of the most effective ways to kill a tumor. But these therapies are indiscriminate, and they can damage healthy tissues.  Now, UC San Francisco scientists have developed a way to deliver radiation just to cancerous cells. The therapy combines a drug to mark the cancer cells for destruction and a radioactive antibody to kill them.   It wiped out bladder and lung tumors in mice ...

A new paper authored by a national team of experts at the intersection of health and spirituality highlights the critical role of the spiritual care provided by chaplains in supporting family members of ICU patients. Chaplains have extensive training, learning to address diverse spiritual as well as religious concerns that have been shown to affect medical decision making. This enables them to support the decision-making ...

During economic, political, or other crises, non-governmental organisations (NGOs) often experience a heightened need for their support and assistance. Yet, the recent global crisis of the COVID-19 pandemic presented unexpected challenges to the NGOs: restrictions on movement imposed by governments prevented them from carrying out their activities and providing certain services. Moreover, despite the increase in demand for NGO services, organisations have faced the problem of raising funding, as some of the usual methods of fundraising have ...

WASHINGTON—Early life exposure to a class of endocrine-disrupting chemicals (EDCs) called polychlorinated biphenyls (PCBs) may lead to behavioral problems in rats, according to a new animal study published in the Journal of the Endocrine Society. Endocrine-disrupting chemicals (EDCs) are chemicals that mimic, block or interfere with hormones in the body's endocrine system and contribute to endocrine diseases such as cancer, reproductive disorders, obesity and neuroendocrine disorders. PCBs have been banned for decades but are still persistent in ...

Researchers have found that the global goal of limiting warming to 1.5 degrees Celsius above pre-industrial levels is now almost certainly out of reach. The results, published Dec. 10 in Geophysical Research Letters, suggest the hottest years ahead will very likely shatter existing heat records. There is a 50% chance, the authors reported, that global warming will breach 2 degrees Celsius even if humanity meets current goals of rapidly reducing greenhouse gas emissions to net-zero by the 2050s. A number of previous studies, including the authoritative ...

Background and Aims Coronary artery disease (CAD) is increasingly observed in patients with liver cirrhosis. However, data on the incidence and prevalence of CAD in cirrhotic patients are heterogeneous, and the association remains uncertain. In this study, we aimed to conduct a systematic review and meta-analysis to address these issues. Methods PubMed, EMBASE, and Cochrane Library databases were searched. Incidence, prevalence, and factors associated with CAD were pooled using a random-effects model. Risk ratio (RR) and odds ratio (OR), with their ...

All living organisms host microbiomes composed of both beneficial and harmful microbes that influence health. Microbiome diversity affects host fitness: low diversity can lead to immune issues and poor nutrient absorption, while high diversity can boost resilience to stress and pathogens. To illuminate this issue, researchers from Florida Atlantic University’s Charles E. Schmidt College of Science, have spent the last five years studying the relationships between songbird gut microbiomes and traits that relate to a bird’s health and breeding success. While links between the gut microbiome and other traits have been described in laboratory experiments with captive animals, ...

Hepatocellular carcinoma (HCC) stands as the dominant form of liver cancer, ranking as the fourth leading cause of cancer-related deaths globally. Often diagnosed at advanced stages, the therapeutic landscape is limited, with transarterial chemoembolization (TACE) serving as a key locoregional treatment. TACE, while effective in inducing tumor necrosis, exerts dual effects on the tumor microenvironment (TME), necessitating integration with systemic therapies like immune checkpoint inhibitors (ICIs). Yet, therapeutic resistance, hypoxia-induced angiogenesis, and immune evasion remain significant barriers. The advent of T-cell receptor (TCR) sequencing offers a transformative lens to ...
