Investigating the influence of molybdenum disulfide quantum dots coated with DSPE-PEG-TPP on molecular structures of liver lipids and proteins: An in vivo study.

Molybdenum disulfide (MoS2) quantum dots (QDs) based therapeutic approaches hold great promise for biomedical applications, necessitating a thorough evaluation of their potential effects on biological systems. In this study, we systematically investigated the impact of MoS2 QDs coated with 1,2-distearoyl-sn-glycero-3-phosphoethanolamine-N-[amino(polyethyleneglycol)-2000](DPSE-PEG) linked with (3-carboxypropyl)triphenyl-phosphonium-bromide (TPP) on molecular structures of hepatic tissue lipids and proteins through a multifaceted analysis. The DSPE-PEG-TPP-MoS2 QDs were prepared and administered to the mice daily for 7 weeks. Liver tissues were subjected to a comprehensive examination using various techniques, including Fourier-transform infrared (FTIR) spectroscopy, UV-vis spectroscopy, and liver function tests. FTIR revealed subtle changes in the lipid composition of liver tissues, indicating potential modifications in the cell membrane structure. Also, the (CH stretching and amides I and II regions) analysis unveiled tiny alterations in lipid chain length and fluidity without changes in the protein structures, suggesting a minor influence of DSPE-PEG-TPP-MoS2 QDs on the liver's cellular membrane and no effect on the protein structures. Further scrutiny using UV-vis spectroscopy demonstrated that DSPE-PEG-TPP-MoS2 QDs had no discernible impact on the absorbance intensities of aromatic amino acids and the Soret band. This observation implies that the treatment with SPE-PEG-TPP-MoS2 QDs did not induce significant alterations in helical conformation or the microenvironment surrounding prosthetic groups in liver tissues. The liver function tests, including ALP, ALT, AST, and BIL levels, revealed no statistically significant changes in these key biomarkers despite minor fluctuations in their values, indicating a lack of significant liver dysfunction. This study provides a detailed understanding of the effects of DSPE-PEG-TPP-MoS2 QDs on hepatic lipids and proteins, offering valuable insights into the biocompatibility and limited impact on the molecular and functional aspects of the liver tissue. These findings could be essential for the application of MoS2 QDs-based therapies.

Tubermycin B coated on Galactosylated Chitosan Nanoparticles synthesized by eco-friendly method ameliorates intracellular free radical production and reduces oxidative stress, reducing phosphorylation of IKKα/ß/pIкBα/NF-кB pathway.

OBJECTIVE: The objective of the current study was to investigate the cytotoxic potentials of Galactosylated Chitosan Nanoparticles. Specifically, the study aimed to develop Tubermycin B coated on Galactosylated Chitosan Nanoparticles using a new green method that replaces sodium borohydride in the reduction process. MATERIALS AND METHODS: The study synthesized Tubermycin B coated on Galactosylated Chitosan Nanoparticles through a new green method. The cytotoxicity of these nanoparticles was evaluated in a mice intestinal tract model that had been induced with chlorpyrifos, which causes oxidative stress-related enterotoxicity. Multiple activities, including the apoptosis of intestinal macrophages and the activation of Ikappa α/ß kinase (IKKα/ß), were examined as indicators of the nanoparticles' efficacy. The stability of the synthesized Chitosan Nanoparticles was also assessed. Additionally, the encapsulation efficiency of Boscia angustifalia and Boscia senegalensis extracts within the nanoparticles was determined. RESULTS: The results of the study showed that Tubermycin B coated on Galactosylated Chitosan Nanoparticles effectively alleviated the oxidative stress-related enterotoxicity in the mice intestinal tract induced by chlorpyrifos. The nanoparticles prevented the apoptosis of intestinal macrophages and inhibited the activation of IKKα/ß. The synthesized chitosan nanoparticles exhibited high stability. The encapsulation efficiency of Boscia angustifalia extract was recorded as 46.58%, whereas for Boscia senegalensis extract, it was 9.77%. The nanoparticles showed no cytotoxicity at all tested concentrations and demonstrated a medium-level anticancer effect. CONCLUSIONS: Based on the findings, it can be concluded that Tubermycin B coated on Galactosylated Chitosan Nanoparticles has the potential to alleviate oxidative stress-related enterotoxicity in the mice intestinal tract. The nanoparticles showed high stability and exhibited a medium-level anticancer effect. Furthermore, the study demonstrated that Boscia angustifalia extract exhibited higher anti-hepatitis C virus antibodies (anti-HCV) activity compared to Boscia senegalensis extract in an in-vitro system. Therefore, Boscia angustifalia could be considered a promising candidate for the development of an anti-HCV drug for future in-vivo studies.

Examining the prevalence of obesity in school children through an on-site obesity outpatient clinics survey based on student's lifestyles.

OBJECTIVE: The purpose of this study was to identify the prevalence of obesity, overweight, and risk factors in pediatric patients attending outpatient clinics at a public sector hospital in the central province of Saudi Arabia. SUBJECTS AND METHODS: This cross-sectional study was conducted in Riyadh, the capital of Saudi Arabia, between January 2022 and October 2022. The target population was aged 6-15 years. We conducted on-site obesity assessments utilizing questionnaire-based interviews with patients attending outpatient clinics. Data collection was carried out with the help of parents, where required. Using BMI growth charts for Saudi children and teenagers, the weight, height, and body mass index (BMI) of subjects were computed. RESULTS: A total of 576 responses with a response rate of 64% were received and included in the study. In the current study, the majority (41.1%) of the patients were aged between 11 and 12 years old, followed by 37.0% of the students aged between 13 and 15 years old, and 21.9% of students aged between 8 and 10 years old. In the current study, 54.2% of the patients had normal weight, 15.6% of patients were underweight, 16.7% of patients were overweight, and 13.5% were obese. In this study, the prevalence of overall obesity was 2.3 times more prevalent in children aged 11 to 12 years (OR=2.30; p=0.03), followed by ~2 times higher levels in children aged 13 to 15 years (OR=2.30; p=0.03). Moreover, 2.11 times higher prevalence of obesity (OR=2.11; p=0.77) in those who regularly took food (especially lunch) from the school cafeteria. A significant ~2.5 high obesity level was recorded for students who consumed fizzy/soft drinks four or more times per week (OR=2.38; p=0.007). CONCLUSIONS: Saudi Arabia still has a high rate of overweight and obesity among children of school-going age, which is a significant public health issue. To properly address and control this issue, policies at the national, local, and individual levels must be implemented. Notably, there was also a high prevalence of being underweight, and this issue needs to be brought up as well.

Protective effect of barbigerone against ethanol-induced ulcers via the interleukins/ICAM-1/Bcl-2 pathway.

OBJECTIVE: The objective of the study was to assess the protective effects of barbigerone in ethanol-induced gastric ulcers in rats. MATERIALS AND METHODS: Male Wistar rats (180±20 g) were used in the study (n=06). The rats were randomly divided into different groups, i.e., the normal group, ethanol control, and barbigerone 10 and 20 mg/kg group. Various biochemical parameters were assessed - total acidity and pH values, oxidative stress biomarkers such as superoxide dismutase (SOD), glutathione (GSH), malondialdehyde (MDA), and catalase (CAT) along with markers, i.e., tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), IL-1ß, intercellular adhesion molecule-1 (ICAM-1) and expression of B-Cell Leukemia/Lymphoma 2 (Bcl-2). Also, histopathology was performed. RESULTS: Treatment with barbigerone in the ethanol-induced-ulcer rats restored the levels of biochemical parameters such as SOD, GSH, MDA, CAT, and markers expression, including TNF-α, IL-6, IL-1ß, ICAM-1, and Bcl-2 with protected against cellular necrosis. CONCLUSIONS: Barbigerone protective effects can be attributed to its ability to reduce oxidative stress and inflammation, as well as promote gastroprotection against ethanol-induced ulcers in rats.

Erythritol alters microstructure and metabolomic profiles of biofilm composed of Streptococcus gordonii and Porphyromonas gingivalis.

The effects of sugar alcohols such as erythritol, xylitol, and sorbitol on periodontopathic biofilm are poorly understood, though they have often been reported to be non-cariogenic sweeteners. In the present study, we evaluated the efficacy of sugar alcohols for inhibiting periodontopathic biofilm formation using a heterotypic biofilm model composed of an oral inhabitant Streptococcus gordonii and a periodontal pathogen Porphyromonas gingivalis. Confocal microscopic observations showed that the most effective reagent to reduce P. gingivalis accumulation onto an S. gordonii substratum was erythritol, as compared with xylitol and sorbitol. In addition, erythritol moderately suppressed S. gordonii monotypic biofilm formation. To examine the inhibitory effects of erythritol, we analyzed the metabolomic profiles of erythritol-treated P. gingivalis and S. gordonii cells. Metabolome analyses using capillary electrophoresis time-of-flight mass spectrometry revealed that a number of nucleic intermediates and constituents of the extracellular matrix, such as nucleotide sugars, were decreased by erythritol in a dose-dependent manner. Next, comparative analyses of metabolites of erythritol- and sorbitol-treated cells were performed using both organisms to determine the erythritol-specific effects. In P. gingivalis, all detected dipeptides, including Glu-Glu, Ser-Glu, Tyr-Glu, Ala-Ala and Thr-Asp, were significantly decreased by erythritol, whereas they tended to be increased by sorbitol. Meanwhile, sorbitol promoted trehalose 6-phosphate accumulation in S. gordonii cells. These results suggest that erythritol has inhibitory effects on dual species biofilm development via several pathways, including suppression of growth resulting from DNA and RNA depletion, attenuated extracellular matrix production, and alterations of dipeptide acquisition and amino acid metabolism.
