Article Abstract
Purpose: Sodium glucose co-transporter (SGLT) 2 inhibitors are oral anti-diabetic drugs with proven kidney protective effects. Renal protective effects in non-diabetic individuals have also been shown in recent studies. The aim of this study was to determine the renal protective effects of dapagliflozin by evaluating the oxidative stress markers in the kidney tissue and demonstrating it in renal histological sections in an iron-overloaded rat model.
Methods: A total of 24 Wistar Albino rats were separated into 3 groups of 8 rats. Iron sucrose (60 mg/kg/day) was administered intraperitoneally to the first group (Group Fe) (n = 8), iron sucrose and dapagliflozin (0.1 mg/kg/day) to the second group (Group Fe + D) (n = 8) and intraperitoneal saline as placebo to the control group (Group C) (n = 8) for 4 weeks. The glomerular changes were semi-quantitatively scored with Oxford Classification. Oxidative stress was analyzed from the tissue fluorescent oxidation product (FLOP), malondialdehyde (MDA) and total sulfhydryl (T-SH) levels.
Results: Dapagliflozin prevented glomerular and mesangial damage of iron overload in the non-diabetic rat model. MDA levels were significantly higher in Group Fe compared to the Group C, and there was no significant difference between the Fe + D group and Group C. T-SH levels were preserved in the Fe + D group and were significantly higher than in the Fe group.
Conclusions: The results of this study showed that dapagliflozin helped preserve the glomerular and mesangial structure histologically and reduced oxidative stress markers in a non-diabetic iron overload rat model.

Functional PET (fPET) identifies stimulation-specific changes of physiological processes, individual molecular connectivity and group-level molecular covariance. Since there is currently no consistent analysis approach available for these techniques, we present a toolbox for unified fPET assessment. The toolbox supports analysis of data obtained with a variety of radiotracers, scanners, experimental protocols, cognitive tasks and species.

Perinatal stroke is a vascular injury occurring early in life, often resulting in motor deficits (hemiplegic cerebral palsy/HCP). Comorbidities may also include poor neuropsychological outcomes, such as deficits in memory. Previous studies have used resting state functional MRI (fMRI) to demonstrate that functional connectivity (FC) within hippocampal circuits is associated with memory function in typically developing controls (TDC) and in adults after stroke, but this is unexplored in perinatal stroke.

Acting intentionally is a major aspect of human cognitive development and depends on the ability to link actions with their consequences. Action-effect binding (AEB) is a fundamental mechanism enabling this. While AEB has been well-characterized in adults, its neurophysiological underpinnings during adolescence remain unclear.

Particles with some degree of hydrophilicity are known to aggregate when directly dispersed in non-aqueous media. Proteins are generally insoluble in oil and have complex surface properties, but they may form networks in oil like more simple colloidal particles, depending on particle size and surface hydrophilicity. Here, the particle size of pea protein isolate (PPI) particles in oil was reduced to submicron sizes by stirred media milling.

Purpose Of Review: Autoimmune nodopathies (AN) are a recognized distinct group of immune-mediated peripheral neuropathies with unique immunopathological features and therapeutic implications. This review synthesizes recent advances in their pathogenesis, diagnosis, and management, which have refined their clinical classification and informed targeted treatment strategies.
Recent Findings: AN are characterized by autoantibodies targeting surface proteins in the nodal-paranodal area (anti-contactin-1, anti-contactin-associated protein 1, anti-neurofascin-155, anti-pan-neurofascin), predominantly of IgG4 subclass.
