Hypovitaminosis D has a negative impact on the cardiovascular system. We performed the current study to investigate the expression of Vitamin D Receptor (VDR) in atherosclerotic human male aortas and to examine the effect of different doses of Vit. D supplementation on VDR expression in the aortas of male rats fed a High-Fat Diet (HFD). Human participants included 50 atherosclerotic male patients with anterior myocardial infarction and 131 control healthy males. Fifty male Wistar rats were divided into 2 groups: Control (Cont.) group; n = 10 and HFD fed rats; n = 40. The latter was divided equally into 4 subgroups according to the dose of Vit. D supplemented. Vitamin D was supplemented in 3 doses: (0.025, 0.05, 0.075 µg/kg) for a duration of 17 weeks. VDR expression score was immunohistochemically evaluated in aortas of both human and animal study groups. The current study revealed that Vit. D levels were significantly lower in atherosclerotic patients with myocardial infarctions compared to the human control group. Concurrent administration of Vit. D suppresses the progress of atheromatous plaque in rats feed a HFD in a dose-dependent manner. Consequently, it could be concluded that Vit. D supplements are recommended as a prophylaxis in patients at high risk of coronary artery disease.

Traditional Coronary Artery Bypass Graft (CABG) is currently among of the chief methods in dealing with patients suffering from atherosclerotic coronary heart disease. The current study aimed to measure and compare the levels of proinflammatory cytokines and oxidative stress marker in patients who underwent multivessels Minimally Invasive Coronary Artery Bypass Graft Surgery (MICS– CABG) versus off-pump Coronary Artery Bypass Grafting (off-pump CABG) in the cardiothoracic department, Assiut University hospitals, Upper Egypt. the study included 67 patients, all of them suffering from atherosclerotic coronary artery disease, which confirm by cardiac catheter angiography. The patients were divided randomly into two groups, first group (A) included 34 patients to whom Multi Vessels Coronary Artery Bypass Graft Surgery (MICS-CABG) under off pump had been done. The second group (B) included 33 patients whom underwent off pump Coronary Artery Bypass Grafting (off-pump CABG). Tumor Necrosis Factor-Α (TNF-α), interlukin-2 (IL-2), lipid peroxides, Superoxide Dismutase (SOD), total thiols and Nitric Oxide (NO) were estimated in sera of all patients by their corresponding methods; 48 h before the operation, 15 min before the operation end and 72 h after the operation. After testing the normality, Mann-Whitney U test and Spearman correlation coefficient were used to compare the two groups and tested the variables’ correlations with the duration of the operation. p≤0.05 was considered significant. Serum TNF-α, IL-2 and lipid peroxides levels were significantly higher while total thiols and SOD were significantly lower, intraoperative and postoperatively, while No was significantly higher intraoperative only, in off-pump CABG group compared to MICS-CABG group and in both groups, intraoperative and postoperatively compared to preoperative levels. Especially in the postoperative samples, TNF-α, IL-2 and NO levels correlated positively while those of SOD correlated negatively with the operation duration the clinical data obtained presented in details in the result sector and revealed that. MICS-CABG group associated with less post-operative pain, less need for blood transfusion, less hospital stays and rapid regain to normal activity. The current study revealed that MICS-CABG is an effective procedure that is associated with small surgical trauma and lower inflammations and oxidative stress compared to off-pump CABG.

Four halophytic plants, Lycium shawii, Anabasis articulata, Rumex vesicarius, and Zilla spinosa, growing in the central Qassim area, Saudi Arabia, were phytochemically and biologically investigated. Their hydroalcoholic extracts’ UPLC-ESIQ-TOF analyses demonstrated the presence of 44 compounds of phenolic acids, flavonoids, saponins, carbohydrates, and fatty acids chemical classes. Among all the plants’ extracts, L. shawii showed the highest quantities of total phenolics, and flavonoids contents (52.72 and 13.01 mg/gm of the gallic acid and quercetin equivalents, respectively), along with the antioxidant activity in the TAA (total antioxidant activity), FRAP (ferric reducing antioxidant power), and DPPH-SA (2,2-diphenyl-1-picryl-hydrazyl-scavenging activity) assays with 25.6, 56.68, and 19.76 mg/gm, respectively, as Trolox equivalents. The hydroalcoholic extract of the L. shawii also demonstrated the best chelating activity at 21.84 mg/gm EDTA equivalents. Among all the four halophytes, the hydroalcoholic extract of L. shawii exhibited the highest antiproliferative activity against MCF7 and K562 cell lines with IC₅₀ values at 194.5 µg/mL and 464.9 µg/mL, respectively. The hydroalcoholic extract of A. articulata demonstrated better cytotoxic activity amongst all the tested plants’ extracts against the human pancreatic cancer cell lines (PANC1) with an IC₅₀ value of 998.5 µg/mL. The L. shawii induced apoptosis in the MCF7 cell lines, and the percentage of the necrotic cells changed to 28.1% and 36.5% for the IC₅₀ and double-IC₅₀ values at 22.9% compared with the untreated groups. The hydroalcoholic extract of L. shawii showed substantial antibacterial activity against Bacillus cereus ATCC 10876 with a MIC value of 12.5 mg/mL. By contrast, the A. articulata and Z. spinosa exhibited antifungal activities against Aspergillus niger ATCC 6275 with MIC values at 12.5 and 50 mg/mL, respectively. These findings suggested that the L. shawii is a potential halophyte with remarkable biological properties, attributed to its contents of phenolics and flavonoid classes of compounds in its extract.
