Behavior and oxidative stress evaluation of scorpion Tityusserrulatus (Lutz & Mello,1922) envenomation with genomic modulation and dopaminergic neutralization by antiscorpionic serum treatment.

Tityus serrulatus accident promote vast symptomatology related to toxins of the venom, which leads to a massive release of neurotransmitters, notably dopamine, affecting behavior and neurochemistry. The recommended treatment for envenomation is the antiscorpionic serum (SAEsc) administration. Related to this complexity of the Tityus serrulatus envenomation, this study aimed to assess organism responses to the venom, its impact on behavior, oxidative stress, neurochemistry, and genetic impacts, as well as the efficacy of SAEsc, especially concerning dopamine levels and genetic interactions.

Biomechanical Evaluation of Physical Examination Tests for Rotator Cuff Tears - A Computer Simulation Study.

Background: Numerous physical diagnostic shoulder tests have been established to determine the presence of rotator cuff tears and to identify the affected muscles. However, reported sensitivities and specificities of these tests vary strongly. The aim of this study was to identify diagnostic postures that are biomechanically most sensitive in identifying rotator cuff lesions and compensation mechanisms.

Biliverdin's Propionic Chains Influence Oligomerization in Sandercyanin.

Sandercyanin is a mildly fluorescent biliprotein with a large Stokes shift, a tetrameric quaternary structure, and a biliverdin (BV) chromophore that does not covalently bond to the protein. To adapt this promising protein for use in bioimaging, it is necessary to produce monomeric mutants that retain the spectroscopic properties while increasing the fluorescence quantum yield. Modulating these properties through the protonation state of BV's propionic tails is a possible avenue, if detailed mechanistic information on the role of such chains becomes available.

Donepezil treatment mitigates cholinergic system alterations, oxidative stress, neuroinflammation and memory impairment induced by branched-chain amino acid administration in rats.

Maple Syrup Urine Disease (MSUD) is an inherited metabolic disorder biochemically characterized by tissue accumulation of leucine, isoleucine, and valine and their derivatives. Patients present with neurological disabilities and treatment is limited. Donepezil, a drug used for neurodegenerative disorders, has been shown to improve memory and counteract oxidative stress and inflammation.

Hemophagocytic Lymphohistiocytosis/Macrophage Activation Syndrome in pediatric Inflammatory Bowel Disease: clinical characteristics and outcomes.

Hemophagocytic Lymphohistiocytosis (HLH)/Macrophage Activation Syndrome (MAS) in children with inflammatory bowel disease (IBD) has been reported only anecdotally. This study aimed at describing the clinical features and outcomes of children diagnosed with both IBD and HLH/MAS. Data on IBD and HLH/MAS characteristics, biochemical, microbiological and genetic assessments, treatments, and outcomes were collected from the Italian Pediatric IBD Registry and presented using descriptive statistics.
