The present investigation was performed with the objective of developing a method to estimate how long a corpse had been immersed in water after death (the time since death). Accurate determination of the time elapsed since death may lead to identification of the place of drowning, and therefore, serves not only as a piece of information useful for determination of the cause of death but also leads to prompt identification of the body. The results showed that diatoms attached to the surface of dental enamel increased with prolongation of immersion time in water. Further, as the immersion time increased, the quantity of O, Si, Mg, K, Al, and S detected on the surface of dental enamel increased, while the quantity of the main dental components (Ca and P) that were detected gradually decreased. Based on these results, we calculated a regression formula to estimate the immersion time. Our method is considered to be a breakthrough technique for evaluating the time since death more objectively, compared to the conventional method of determination based on the degree of decomposition of the corpse.

Background: Solid organ transplant (SOT) recipients are not only at increased risk of morbidity and mortality due to acute COVID-19 but may also experience poor long-term outcomes due to post-acute COVID-19 syndromes, including long COVID.
Methods: This retrospective, registry-based chart review evaluated graft failure and mortality among SOT recipients diagnosed with COVID-19 at a large, urban transplant center in Houston, Texas, USA. Patient populations were analyzed separately according to their long COVID status at the time of transplant to preserve the temporal relationship between the exposure (long COVID) and the outcome (graft failure or mortality).

S-glutathionylation (SSG), a redox-sensitive post-translational modification mediated by glutathione, regulates protein structure and function through reversible disulfide bond formation at cysteine residues. Glutaredoxins (GRXs), pivotal antioxidant enzymes, catalyze SSG dynamics to maintain thiol homeostasis. Recent advances in redox proteomics have revealed that SSG dysregulation is intricately linked to neurodegenerative, cardiovascular, pulmonary and malignant diseases.

The emergence of the Novel COVID-19 Pandemic has undoubtedly impacted the lives of individuals across the globe. It has drawn the attention of major public health agencies as they work intensely towards understanding the behavior of the virus causing the disease, while simultaneously establishing ways to curb the spread of the virus among populations. As of the time of writing, 7,949,973 confirmed cases have been reported globally; with the United States (US) contributing to 26.

Background: Falls are a major cause of injury and death among the elderly, highlighting the need for effective and real-time detection systems. Embedded Internet of Health Things (IoHT) technologies integrating sensors, microcontrollers, and communication modules offer continuous monitoring and rapid response. However, the research landscape remains fragmented, and no comprehensive bibliometric review has been conducted.

Background: Seasonal variation in mortality results from a combination of environmental, biological, and social factors, with ambient temperature recognized as a key contributor. However, comprehensive assessments disentangling temperature effects from other seasonal influences across a broad range of mortality causes remain limited. This study aimed to quantify and compare the mortality burden attributable to ambient temperature and broader seasonal variation across major causes of death in Spain.
