In the current study,Bacillus velezensisAG6 was isolated from sediment samples in the Red Sea, identified by traditional microbiological techniques and phylogenetic 16S rRNA sequences.

Objective: This study intended to examine the effects of Pilates exercise on pain, cardiorespiratory fitness, functional ability, and quality of life in children with polyarticular juvenile idiopathic arthritis. Methods: Forty children with polyarticular JIA aged 10–14 years old were randomly allocated into two groups: the control group (n = 20) received conventional physical therapy (CPT), and the experimental group (n = 20) received clinical Pilates exercises combined with CPT. Patients in both groups received their program three times/week for 3 months. Pain, cardiorespiratory fitness, functional ability, and quality of life were assessed through the visual analogue scale, cardiopulmonary exercise test, 6 min walk test, and PedsQL scale, respectively, just before and after treatment. Results: Pain (p = 0.001), cardiorespiratory markers (all p < 0.05), functional ability (p = 0.002), and overall quality of life (p = 0.007) improved significantly in the experimental groups compared to the control group. Conclusion: Incorporating Pilates exercises into CPT is likely more effective for decreasing pain intensity, improving cardiorespiratory fitness, augmenting functional ability, and promoting quality of life in children with JIA than CPT alone.

Microbial exopolysaccharides (EPSs) are gaining interest as alternatives to chemical antioxidants and pharmaceuticals. This study mines the promising biomedical and antimicrobial potential of a marine bacterium, a prolific EPS producer, isolated from the Red Sea. Pseudomonas sp. strain AHG22 generated an EPS weighing 6.98 g·L⁻¹, coded EPSF8, subjected to FT-IR and HPLC chemical analysis. EPSF8 was then investigated for antioxidant assessment by 2,2-diphenyl-1-picrylhydrazyl (DPPH), H₂O₂, ABTS˙ ⁺ , nitric oxide, total antioxidant capacity (TAC), and ferric reducing antioxidant power (FRAP). EPSF8 had an IC₅₀ of 46.99 μg·mL⁻¹ in the DPPH antioxidant assay and antioxidant capacities of 219.45 μg·mg⁻¹ ascorbic acid equivalent (AAE) in the TAC assay and 54.15 μg·mg⁻¹ AAE in the FRAP assay. The in vitro anti-inflammatory effect of EPSF8 was tested against 5-lipoxygenase (5-LOX) and cyclooxygenase-2 (COX-2) enzymes and compared with the drugs ibuprofen and celecoxib used as controls. The IC₅₀ values of 5-LOX, COX-2, ibuprofen, and celecoxib were found to be 14.82, 15.49, 1.5, and 0.28 μg·mL⁻¹, respectively. Additionally, EPSF8 revealed antidiabetic activity toward α-amylase and α-glucosidase, and the IC₅₀ values were 93.1 and 127.28 μg·mL⁻¹, compared to those of acarbose (50.93 and 4.13 μg·mL⁻¹, respectively). Anti-obesity activity of EPSF8 by lipase inhibition revealed IC₅₀ = 56.12 μg·mL⁻¹ compared to orlistat (IC₅₀ = 20.08 μg·mL⁻¹) as a control. EPSF8 displayed antibiofilm and bactericidal activity against Gram-positive (G +ve) and Gram-negative (G −ve) ATCC pathogenic bacterial strains. It had a minimum bactericidal concentration/minimum inhibitory concentration ratio ≤2, indicating a broad bactericidal spectrum. Furthermore, EPSF8 is evidenced to have a promising anti-butyrylcholinesterase activity for the control of Alzheimer’s disease. The findings of the present analysis suggest that the isolated Pseudomonas sp. strain AHG22 EPS can potentially be explored as a promising green therapeutic compound.

This study explored the metabolites and bioactive potential of the ethyl acetate extract from a marine-derived fungal strain, Aspergillus oryzae NGM91, isolated from Red Sea sediments.

The global COVID-19 pandemic has caused countries to develop novel methods to detect and trace active cases. These methods aim to limit its spread; however, they can also be used to detect other endemic infectious diseases, such as tuberculosis (TB). The current methods used to detect COVID-19 cases, such as temperature-checking and tracing applications, led to the detection of these specific TB cases and their referral to the hospital. In this study, we present four cases of TB in which the patients come from different working backgrounds. We conclude that the current measures used for COVID-19 could also prove to be beneficial in the context of other infectious diseases, mainly TB.
