1. Indol is more hemolytic in the presence of a deficiency complex than when a normal diet is fed. 2. The hemolytic effect can be abolished by supplementing the deficient diet with liver extract curative of pernicious anemia in man. 3. The hemolysis affects all hemoglobin-containing cells, including reticulocytes. 4. The repair of the anemia resulting from the administration of indol in the presence of a deficiency represents the cessation of a hemolytic process. 5. An abnormally low rate of production of erythrocytes may well be a factor in the production of the anemia.

Background: Ferroptosis is a recently studied form of programmed cell death characterized by lipid peroxides accumulation in the cells. This process occurs when a cell's antioxidant capacity is disturbed resulting in the inability of the cell to detoxify the toxic peroxides. Two major components that regulate ferroptosis are cysteine and iron.

This case report discusses an innovative approach to abdominal wall reconstruction in a 19-year-old male patient with PBS and associated conditions, including chronic renal failure and spina bifida. Previously, he underwent distal ureterectomy and vesicoureteral reimplantation at the age of two years to correct urinary tract dilation and bilateral orchiopexy.

Fracture is an under-recognized but common complication of diabetes mellitus, with an incidence approaching twofold in type 2 diabetes mellitus (T2DM) and up to sevenfold in type 1 diabetes mellitus (T1DM) compared with that in the general population. Both T1DM and T2DM induce chronic hyperglycaemia, leading to the accumulation of advanced glycosylation end products that affect osteoblast function, increased collagen crosslinking and a senescence phenotype promoting inflammation. Together with an increased incidence of microvascular disease and an increased risk of vitamin D deficiency, these factors reduce bone quality, thereby increasing bone fragility.

Objectives: To investigate the regulatory role of nucleotide-bound oligomerized domain-like receptor containing pyrin-domain protein 6 (NLRP6) in liver lipid metabolism and non-alcoholic fatty liver disease (NAFLD).
Methods: Mouse models with high-fat diet (HFD) feeding for 16 weeks (=6) or with methionine choline-deficient diet (MCD) feeding for 8 weeks (=6) were examined for the development of NAFLD using HE and oil red O staining, and hepatic expressions of NLRP6 were detected with RT-qPCR, Western blotting, and immunohistochemical staining. Cultured human hepatocytes (LO2 cells) with adenovirus-mediated NLRP6 overexpression or knock-down were treated with palmitic acid (PA) in the presence or absence of compound C (an AMPK inhibitor), and the changes in cellular lipid metabolism were examined by measuring triglyceride, ATP and β-hydroxybutyrate levels and using oil red staining, RT-qPCR, and Western blotting.

Primary hyperparathyroidism is now predominantly an asymptomatic pathology, as blood calcium assay has become systematic. Diagnosis therefore requires screening for target organ damage when this is not already indicative of primary hyperparathyroidism.Classical clinical manifestations include bone, kidney and muscle signs, and are characterized by reversibility after parathyroid surgery.
