Department of Chemistry, Faculty of Mathematics and Sciences, Universitas Indonesia, Jakarta, Indonesia.
Electrochemiluminescence (ECL) of luminol and electrocatalysis by Prussian blue were compared for the selective detection of HO at the boron-doped diamond (BDD) electrodes. The HO detection was optimized by various parameters such as the applied potential at pH 7.4, which is a physiological value usually used for HO detection in enzymatic reactions.

Rapid reduction of body size in populations responding to global warming suggests the involvement of temperature-dependent physiological adjustments during growth, such as mitochondrial alterations, in the efficiency of producing metabolic energy, a process that is poorly explored, especially in endotherms. Here, we examined the mitochondrial metabolism and proteomic profile of red blood cells in relation to body size and cellular energetics in nestling shearwaters (Calonectris diomedea) developing at different natural temperatures. We found that nestlings of warmer nests had lighter bodies and smaller beaks at fledging.

Astaxanthin (AST), as a natural antioxidant, has broad application prospects in medicine and health products. However, its highly unsaturated structure and significant lipophilic characteristics limit its dispersibility and bioavailability, thereby restricting its application in food, medicines, and nutraceuticals. To overcome these limitations, researchers have proposed the use of nano delivery systems.

Department of Gastrointestinal Surgery, Central Hospital Affiliated to Shandong First Medical University, China.
Tailgut cyst is an exceedingly rare congenital anomaly originating from embryonic remnants of the tailgut. Owing to its asymptomatic nature in the early stages, it is prone to clinical misdiagnosis. We present a case of a 55-year-old female with initial symptoms manifesting as sacrococcygeal pain.

Division of Surgery, Tygerberg Hospital, Stellenbosch University, South Africa.
Background: Bowel trauma, encompassing injuries to the small and large intestine, represents a significant medical challenge due to its potential for morbidity and mortality. Management of bowel injuries remains surgical, but multiple factors influence the outcome in these patients. This study provides an in-depth analysis of the high-risk features of hollow visceral trauma in the ICU setting and the corresponding mortality rates, shedding light on the critical factors that influence outcomes in these cases.
