Frostbite injury refers to cold tissue injury which typically affects the peripheral areas of the body, and is associated with limb loss and high rates of morbidity. Historically, treatment options have been limited to supportive care, leading to suboptimal outcomes for affected patients. The pathophysiology of frostbite injury has been understood in recent years to share similarity with that of cold ischemia-reperfusion injury as seen in solid organ transplantation, of which mitochondria play an important contributing role.

Spaceflight-induced multi-organ dysfunction affects the health of astronauts and the safety of in-orbit flight. However, the effect of microgravity on the kidney and the underlying mechanisms are unknown. In the current study, we used a hindlimb unweighting (HU) animal model to simulate microgravity and employed histological analysis, ischemia-reperfusion experiments, renal ultrasonography, bioinformatics analysis, isometric force measurement, and other molecular experimental settings to evaluate the effects of microgravity on the kidneys and the underlying mechanisms involved in this transition.

Methods: In our retrospective study of 108 newly diagnosed MM (NDMM) patients from January 2021 to October 2023, we identified four cases of DRESS. The clinical characteristics such as clinical manifestations, laboratory results, treatment and outcome were analyzed.
Investigation of the Effects of Fosfomycin in Kidney Damage Caused by CLP-Induced Sepsis.

Department of Histology and Embryology, Faculty of Medicine, Ondokuz Mayıs University, 55139 Samsun, Turkey.
Sepsis, a life-threatening condition characterized by dysregulated host responses to infection, often leads to multi-organ dysfunction, including kidney injury. Kidney damage in sepsis can have severe consequences and is associated with high mortality rates. This study aimed to investigate the potential therapeutic effects of fosfomycin (FOS), a broad-spectrum antibiotic with immunomodulatory properties, on kidney damage induced by cecal ligation and puncture (CLP)-induced sepsis in a rodent model.

: The bite of the Loxosceles spider is a public health problem around the world, mainly in Latin America. The viscerocutaneous presentation is related to the inoculation of toxins (phospholipase-D) that generates a systemic inflammatory reaction with a subsequent increase in cytokines and chemokines. Hemoadsorption is proposed as a therapy that allows for the removal of the toxin and modulation of the inflammatory response in this disease.
