The Bexar County Medical Examiner's Office in San Antonio, Texas, has encountered 3 cases within a 15-month period involving decedents who were pronounced dead by brain death or cardiac death examination and who had elevated, if not toxic concentrations of pentobarbital present at the time of examination. The elevated levels of pentobarbital were discovered during an autopsy examination performed for medicolegal reasons. The diagnosis of brain death and the implications of pentobarbital intoxication during a brain death examination are discussed.

Organ transplants are used to treat many end-stage diseases, but a shortage of donors means many patients cannot be treated. Xenogeneic organs have become an important part of filling the donor gap. Many current studies of kidney, heart, and liver xenotransplantation have used gene-edited pig organs on brain-dead recipients.

Background: Our aim was to develop a quantitative model for immediately estimating the risk of death and/or brain injury in late-onset sepsis (LOS) in preterm infants, based on objective and measurable data available at the time sepsis is first suspected (i.e., time of blood culture collection).

It has been reported that the nervous system can regulate immune reactions through various mechanisms. However, the role of splenic sympathetic nerve activity in the autoimmune reactions during the pathogenesis of experimental autoimmune encephalomyelitis (EAE) remained unclear. Here, we blocked the activity of the splenic sympathetic nerve and found that the number of adaptive immune cells, such as CD4 T cells, CD8 T cells and B cells, were upregulated.

Temozolomide is universally used to treat glioblastoma due to its unique ability to cross the blood-brain barrier and inhibit tumor growth through DNA alkylation. However, over time, the inevitable emergence of resistance to temozolomide impedes successful treatment of this cancer. As a result, there is an urgent need to identify new therapeutic targets to improve treatment outcomes for this malignancy.

Alzheimer's disease (AD) is a neurodegenerative disorder characterized by cognitive decline and memory loss. A critical aspect of AD pathology is represented by oxidative stress, which significantly contributes to neuronal damage and death. Microglia and astrocytes, the primary glial cells in the brain, are crucial for managing oxidative stress and supporting neuronal function.
