In this study, analysis of antioxidant defense was performed on the blood samples from 184 "aged" individuals aged 65-90+ years, and compared to the blood samples of 37 individuals just about at the beginning of aging, aged 55-59 years. Statistically significant decreases of Zn,Cu-superoxide dismutase (SOD-1), catalase (CAT), and glutathione peroxidase (GSH-Px) activities were observed in elderly people in comparison with the control group. Moreover, an inverse correlation between the activities of SOD-1, CAT, and GSH-Px and the age of the examined persons was found. No age-related changes in glutathione reductase activities and malondialdehyde concentrations were observed. These lower activities of fundamental antioxidant enzymes indicate the impairment of antioxidant defense in the erythrocytes of elderly people. Towards Bioprinted Corneas https://www.fightaging.org/archives/2019/06/towards-bioprinted-corneas/ While no tissues can be said to be simple, some are simpler than others. In the past decade, tissue engineers have made considerable progress towards the manufacture of these simpler tissues, from the starting point of cells and scaffold materials. Bioprinting, a form of rapid prototyping, has proven to be an important class of approach. The research noted here is a representative example of progress towards the production of corneas to replace those that are damaged by accident or age, and thus eliminate the need for donor tissue. ...

Authors: Pennisi PA, Fernández MC, Martin A Abstract Pheochromocytomas/paragangliomas (PCCs/PGLs) are rare neuroendocrine tumors, developed from chromaffin cells derived from the neural crest. From a genetic point of view PCCs/PGLs are divided as sporadic cases, and inherited cases as part of hereditary (familial) syndromes. While the majority is benign, up to 26% of PCCs/PGLs will undergo malignant transformation. Validated prognostic pathological parameters for malignant PCCs/PGLs are still lacking. Signaling that follows the interactions between IGFs and their receptor/s in tumor cells received extensive ...

Authors: Silva MAFS, Dechichi P, Limirio PHJO Abstract Childhood obesity is a considerable worldwide health problem and a major risk factor for several chronic diseases. Fat rich diets result in altered serum levels of lipids, cytokines and hormonal factors, which influence skeletal acquisition and promote microstructural and mechanical behavior changes in bone, especially to bone quality and quantity. However, the possible longterm implications of high-fat diets in childhood are controversial. Despite not fully understood, multiple signaling pathways which support bone tissue homeostasis are altered under hyperlip...

Authors: Scheffer-Rath ME, Boot AM Abstract Vitamin D is important for skeletal growth, bone mineralization and dental health. Vitamin D deficiency is reported in many countries, may have several causes and can cause rickets in children. A guideline with recommendations of vitamin D supplementation to prevent nutritional rickets was published recently. The vitamin D receptor is present in many cells of the body including cells of the immune system. Many studies have been published on associations between vitamin D deficiency and extra skeletal effects, mainly without proof of causality in intervention studies. This...

ConclusionsNo difference between the LSTR and pulpectomy approaches could be confirmed by meta-analyses. The quality of evidence according to the GRADE scheme ranged from moderate to very low.Clinical relevanceThe present meta-analyses could not demonstrate the superiority of one treatment over the other.

Authors: Plunk EC, Richards SM Abstract The epigenome of an individual can be altered by endogenous hormones, environment, age, diet, and exposure to endocrine disrupting chemicals (EDCs), and the effects of these modifications can be seen across generations. Epigenetic modifications to the genome can alter the phenotype of the individual without altering the DNA sequence itself. Epigenetic modifications include DNA methylation, histone modification, and aberrant microRNA (miRNA) expression; they begin during germ cell development and embryogenesis and continue until death. Hormone modulation occurs during the agei...

Authors: Antinozzi C, Sgrò P, Di Luigi L Abstract Among metabolic diseases, carbohydrate metabolism disorders are the most widespread. The most common glucose pathological conditions are acquired and may increase the risk of type 2 diabetes, obesity, heart diseases, stroke, and kidney insufficiency. Phosphodiesterase type 5 inhibitors (PDE5i) have long been used as an effective therapeutic option for the treatment of erectile dysfunction (ED). Different studies have demonstrated that PDE5i, by sensitizing insulin target tissues to insulin, play an important role in controlling the action of insulin and gluco...

The association between preoperative vitamin D deficiency (VDD) and the development of more severe postoperative hypocalcemia is still unclear. Objectives. To evaluate the effect of preoperative VDD on severity of hypocalcemia in patients with hypoparathyroidism following thyroidectomy. Methods. Patients who developed acute hypoparathyroidism after total or completion thyroidectomy, defined as postoperat...

Authors: Hu B, Zhao M, Luo D, Yu C, Shao S, Zhao L, Yang Y, Zhang X, Zhao J, Gao L Abstract Hypothyroidism is a common disease, and its molecular mechanism still needs further investigation. Lysine succinylation is found to be involved in various metabolic processes associated with hypothyroidism. We performed quantitative analysis on lysine succinylome in thyroids of rats with hypothyroxinemia, which was induced through the administration of a high-fat diet. Overall, 129 differentially expressed proteins were quantified. Downregulated proteins were enriched in the thyroid hormone synthesis and thyroid hormone sign...
