Acute kidney injury (AKI) remains a major clinical concern owing to its association with elevated morbidity and mortality. The nuclear protein high-mobility group box protein 1 (HMGB1), recognized for its evolutionary conservation, has emerged as a key mediator in AKI pathogenesis. Upon cellular inj...

This study aimed to investigated metabolism and browning-related enzyme differences of Fuji apples in fresh (FC), browning pulp (BR), and browning inhibition pulp (CM) at 0, 4, 6, and 8 months of storage. Apples stored for 4-months exhibited the highest browning rate and color differences, with brow...

Avian coccidiosis (AC) is a parasitic disease caused by the protozoan parasite Eimeria tenella (E.tenella), which primarily parasitizes the cecum of chickens, resulting in a reduction of their production capacity. Areca alkaloids(AAl), derived from the plant Areca catechu L, have been repeatedly rep...

We present the case of a 68-year-old man with acute kidney injury that occurred following radiofrequency cardiac ablation. Laboratory tests revealed elevated serum creatinine (SCr), positivity for antinuclear and anti-double-stranded DNA (anti-dsDNA) antibodies, elevated IgG4 levels, and hypocomplem...

In this paper, a wideband microwave delay system with an equivalent 440-km fiber link is presented. The fiber link propagation delay fluctuation, suffering from temperature variation, is detected incorporating with a reference RF signal. With the help of a variable optical delay line, the wideband m...
