Monosodium glutamate (MSG) is a major taste enhancer that is used as a food additive. Vitamin C (Vit C) and Nigella sativa oil (NSO) are known for their potent antioxidant activities.
This study investigates the adverse effect of MSG on the thyroid gland and cerebellum of adult male albino rats and the protection against MSG-mediated toxicity provided by Vit C and NSO.

Fifty rats were divided into five groups that were treated via oral gavage. Group I (control) rats received distilled water, Group II rats were treated with MSG (6 mg/gm body weight/day), Group III rats were treated with MSG and Vit C (100 mg/kg body weight /day), Group IV rats were treated with MSG and NSO (50 mg/kg body weight two times per week), and Group V rats were treated with MSG together with both Vit C and NSO with MSG. After 60 days of treatment, rats were euthanized and histological sections were prepared from the thyroid gland and the cerebellum for routine staining and immunohistochemical detection of glial fibrillar acidic procant protection against the oxidative damage induced by MSG.This study investigated the delivery of S-nitrosothiol (GSNO) as a nitric oxide (NO) donor loaded into calcium carbonate-based mineralized nanoparticles (GSNO-MNPs) to regulate cell signaling pathways for the osteogenic differentiation of mouse embryonic stem cells (ESCs). GSNO-MNPs were prepared by an anionic block copolymer template-mediated calcium carbonate (CaCO3) mineralization process in the presence of GSNO. GSNO-MNPs were spherical and had a narrow size distribution. GSNO was stably loaded within the MNPs without denaturation. TEM analysis also demonstrated the localization of GSNO-MNPs within membrane-bound structures in the cell, indicating the successful introduction of GSNO-MNPs into the cytosol of ESCs. Intracellular levels of NO and cGMP were significantly increased upon treatment with GSNO-MNPs, compared with the control group. When cells were exposed to GSNO-MNPs, the effects of nanoparticles on cell viability were not statistically significant. GSNO-MNPs treatment increased ALP activity assay and intracellular calcium levels. Real-time RT-PCR also revealed highly increased expression levels of the osteogenic target genes ALP, osteocalcin (OCN), and osterix (OSX) in GSNO-MNP-treated ESCs. The protein levels of OSX and Runt-related transcription factor 2 (RUNX2) showed similar patterns of expression based on real-time RT-PCR. These results indicate that GSNO-MNPs influenced the osteogenic differentiation of ESCs. Transcriptome profiling identified several significantly enriched and involved biological networks, such as RAP1, RAS, PI3K-AKT, and MAPK signaling pathways. These findings suggest that GSNO-MNPs can modulate osteogenic differentiation in ESCs via complex molecular pathways.The aim of this research is to perform an analysis of the epineurial and endoneurial blood vessels in relation to aging. The research is conducted on samples of the human sciatic nerve of 12 case (age from 27 to 89). The histological sections are stained by streptavidin-biotin method of detecting the presence of Type IV collagen. After morphometric analysis the following stereological parameters have been calculated the number of blood vessels per unit of area, the volume density of the blood vessels and the surface density of the blood vessels of the epineurium and endoneurium. An additional diameter measurement is performed for the endoneural blood vessels. In order to perform a more detailed analysis, the cases were classified into three age groups, the first (27-48 years), the second (49-70 years) and, the third (over 70 years). The bivariate correlation analysis showed that the number of blood vessels of the endoneurium, their volume and surface densities in relation to age produced a statistically significant positive correlation. One Way ANOVA test demonstrated a statistically significant increase in the number of endoneurial blood vessels in the age group III when compared the age group I and, in addition, it showed a significant decrease in the diameter of the age group II when compared to the age group I. Paired t - test shows a statistically significant higher number of endoneurial blood vessels in relation to the epineurial, namely, in the age group III. The volume and surface density of the epineurial blood vessels is significantly higher than the endoneurial in both the I and II age group. Age brings about significant changes of the endoneurial vascular network of the sciatic nerve due to the increase in density of the endoneurial blood vessels, their volume and surface densities. Consequently, in the cases older than 70 years, the number of endoneurial blood vessels significantly exceeds the number of epineurial blood vessels.Obesity is a growing threat. In recent years, the finding of functional brown adipose tissue (BAT) in adult humans implemented the studies of anti-obesity therapies based on triggering energy expenditure. The activation of BAT thermogenesis and the recruitment of brite (brown-in-white) adipocytes are under noradrenergic control. Brain-derived neurotrophic factor (BDNF), if centrally administered, enhances thermogenesis through sympathetic activation, but its direct effect on adipocytes is still unclear. The phenotypic change from fat storing to thermogenic adipocytes is recognized by the presence of multilocular lipid droplets (LDs) and fissed mitochondria that tend to surround LDs, maximizing the efficiency of fatty acid release for thermogenesis. BDNF treatment on differentiated 3T3-L1 adipocytes was compared to negative (CTRL) and positive (norepinephrine, NE) controls. Tenapanor research buy BDNF significantly increased small globular mitochondria percentage (>150% CTRL), while the area surface and elongation index of branched tubules were respectively 55% and 10% lower than NE. Canonical discriminant analysis of mitochondria morphological data clearly separated differentially treated cells with 85% of the total variance. The expression of brown markers and mitochondrial dynamic genes was significantly affected by BDNF. Investigating the pathways involved in adipocyte BDNF stimulation could clarify its role in thermogenesis and its possible local regulation.
