Dead time is an important parameter in time-to-digital converters, which is the significant time measure circuit. To reduce the dead time, this note proposes a new fine-time measurement circuit. In this configuration, two clocks having a phase difference of 180° are used to sample the signals passing through the delay chain, and their average is taken as the final measurement result. The experimental results demonstrate that the dead time of the proposed circuit is observed to be 1.25 ns at 800 MHz clock and the circuit logic resource consumption of the proposed circuit is reduced by approximately 25% compared to other methods.

The dynamic monitoring of cell death processes remains a significant challenge due to the scarcity of highly sensitive molecular tools. In this study, two hemicyanine-based probes (5a-5b) with D-π-A structures were developed for organelle-specific viscosity monitoring. Both probes exhibited correlation with the Förster-Hoffmann viscosity-dependent relationship (R > 0.

Background: Liver transplantation is the definitive treatment for end-stage liver disease and some cancers. The use of livers from donors following pre-donation cardiac arrest (PDCA), especially with prolonged downtime duration, has been limited outside of the US due to fears over inferior outcomes from ischemic injury. However, PDCA may induce ischemic preconditioning, paradoxically improving post-transplant outcomes.

Capturing the dynamic changes in patients' internal states as they approach death due to fatal diseases remains a major challenge in understanding individual pathologies and improving end-of-life care. However, existing methods primarily focus on specific test values or organ dysfunction markers, failing to provide a comprehensive view of the evolving internal state preceding death. To address this, we analyzed electronic health record (EHR) data from a single institution, including 8,976 cancer patients and 77 laboratory parameters, by constructing continuous mortality prediction models based on gradient-boosting decision trees and leveraging them for temporal analyses.

Histological analysis is a method commonly used in medical clinics to evaluate biological tissues and their abnormalities. However, this method is based on tissue collected from the necropsy of the animal, where modifications in the tissue associated with autolysis can occur after death. This study analyses the post-mortem histomorphological changes in white shrimp (Penaeus vannamei) after euthanasia by clove oil anaesthesia induction and pithing as a secondary killing method.

Bacoside A (BCA), a triterpenoid saponin isolated from Bacopa monnieri, exhibits diverse pharmacological properties, including neuroprotective, hepatoprotective, anti-stress, anti-inflammatory, and anti-ulcer effects. In the present study, BCA demonstrates pronounced anticancer activity against K562 chronic myelogenous leukemia (CML) cells by modulating autophagy-apoptosis dynamics. BCA induces dose- and time-dependent cytotoxicity in K562 cells while sparing normal human peripheral blood mononuclear cells (hPBMCs) and Vero cells, indicating therapeutic selectivity.
