This preliminary study, suggests urinary TGF-Beta-1 and NGF as a potent marker in children with NDOA, as they decline following BoNT-A injection. Further studies are needed in identifying their special role in assessing treatment success after invasive interventions.

Spirulina platensis is a microalga that may be a source of antioxidants that can reduce body fat deposition. Consumption of a high fat diet produces elevated blood lipid levels, inflammation and apoptosis. We investigated the possible effects of S. platensis on the blood lipid profile, and liver inflammation and apoptosis in rats fed a high fat diet. Sixty-four young male rats were divided into eight equal groups. The control group was fed a basic diet. The experimental groups were fed a diet for 60 days that was prepared by mixing variable amounts of 43% vegetable oil and 10% cholesterol with or without 3% S. platensis mixed with the basal diet. Blood and liver tissue samples were collected from each animal. Serum samples were used to analyze lipid parameters, total antioxidant status and total oxidant status. iNOS and eNOS were determined by immunohistochemistry. TUNEL staining was used to detect apoptosis to investigate a possible connection between inflammation and apoptosis in the liver tissue. The relations between fat deposition and liver degeneration were assessed by Sirius red staining and alpha-smooth muscle actin immunostaining. S. platensis reduced serum HDL-C, LDL-C and triglyceride, increased HDL-C levels in rats fed a high fat diet to near control levels, and reduced iNOS levels and increased eNOS levels in the liver tissue compared to vegetable oil and cholesterol treated groups. The apoptotic index was reduced in the groups that were fed a high fat or a basic diet when supplemented with S. platensis.

Ghrelin is a peptide hormone which plays important role in maintaining growth hormone release and energy homeostasis in vertebrates. Spirulina platensis (SP) has antioxidant and hypolipidemic effects due to its ingredients. In this study we aimed to investigate the effects of SP on the testicular structure and relation between ghrelin and testosterone in the testis of rats fed a high fat diet (HFD). Sixty four young adult male rats were used and divided to 8 equal groups. Experimental groups received addition of 10% cholesterol (CHL), 43% hydrogenated vegetable oil (HVO) and 3% SP alone or in combination to basal diet while the control group received only basal diet. Serum ghrelin and testosterone levels were measured with ELISA. Receptors for ghrelin and androgen were detected with immunohistochemistry. For histomorphometric investigation, tubulus seminiferus, intertubular area, tubulus seminiferus lumen, Leydig cell nucleus, Sertoli cell nucleus, germ cell nucleus, spermatocyte nucleus and elongated spermatid volume densities were determined stereologically. Serum ghrelin level was increased especially in HVO and CHL combination group compared to the control while serum ghrelin levels were close to control levels in SP-received groups. Ghrelin receptor level was increased in tubulus seminiferus with HVO+CHL administration but this effect was, however, limited in HVO+CHL and SP challenged groups. HVO+CHL administration caused a significant decrease in Leydig cell nucleus volume density, as well as in all SP-received groups, compared to the control. Significantly increased spermatocyte nucleus volume density in cholesterol-receiving groups was decreased to control level with SP alone and its combinations.

Objective The aim of this study was to determine the availability of serum amyloid A (SAA) in the diagnosis of coronavirus disease 2019 (COVID-19), to asses disease severity and to predict hospitalization status. Methods Between March, 2020 and March, 2021, a total of 80 children (40 cases with COVID-19 and 40 cases in healthy group) were included in this study. Patients were divided into two groups (mild and moderate/severe) to evaluate SAA levels in terms of clinical severity and also hospitalization status. Results Comparisons between the two groups revealed that median SAA values were significantly higher in children with COVID-19 than in their healthy peers (21.45vs3.05 mg/L, P =0.002). There was no significant difference in the median serum SAA levels between mild and moderate/severe clinical disease ( P =0.837). The SAA difference between the two groups with regards to hospitalization was not statistically significant ( P =0.098). Conclusions Although SAA level was found to be higher in children with COVID 19 compared to healthy controls, the sensitivity of SAA for the disease was found to be low. In addition, there was no difference between the groups in terms of clinical severity.
