Cytotoxic activity of Thymus capitatus collected from Hail region in Saudi Arabia with mechanistic study via induction of caspase-dependent apoptosis and S-phase arrest

Thymus capitatus is a plant grows in Mediterranean area and some Arab countries such as Saudi Arabia. It possesses numerous medicinal values. Its common name is Zaatar and it belongs to family Lamiaceae Thymus capitatus leaves and stem were collected from Hail region, Saudi Arabia. Then both leaves and stem were extracted with ethanol. This study was performed to evaluate cytotoxic activity of Thymus capitatus leaves and stem ethanolic extract in details. Doxorubicin was used as a standard and the relevant half maximal inhibitory concentration (IC50) values were computed for each cell line by 3-(4,5- diemthylthiazole-2-yl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay. In addition, further mechanistic study was carried out by using Apoptosis assay to explore cytotoxic activity of plant extract. Both leaves and stems extracts were screened against HepG2, A-549, HCT-116 and   MCF-7 cancer cell lines. It was found that leaves’ extract shows high and moderate cytotoxic activity against both A-549 and HepG2 cancer cell lines, respectively (with IC50 = 13.6 and 21.5 μg/ml, respectively), while stem’s extract exerted moderate cytotoxic activity against A-549 cancer cell lines (with IC50 = 21.38 μg/ml).  Further mechanistic study was carried out on A-549 cells by using apoptosis assay. It showed that leaves’ extract resulted in arrest of S-phase and caused apoptosis through activation of caspase-3, p53 and Bax, in addition to down regulation of Bcl-2

Quality of Sleep and Its Effect on Glycemic Control

Diabetes mellitus (DM) is a widespread illness that affects around 347 million individuals globally. DM not only has many clinical implications but also has a detrimental impact on the quality of sleep in patients. Insufficient sleep quality hinders the proper regulation of blood sugar levels, which is considered a fundamental aspect of managing diabetes. It also has other harmful repercussions that significantly affect one's overall quality of life. Increasing data suggests that sleep disturbances and sleep deprivation have an impact on glucose metabolism and insulin resistance. Simultaneously, changes in glucose metabolism can potentially affect the quality of sleep. The association between T2DM and sleep-disturbed breathing has been thoroughly investigated. Individuals diagnosed with T2DM exhibit a remarkably elevated incidence of obstructive sleep apnea, which subsequently leads to suboptimal management of blood sugar levels. Conversely, the correlation between T1DM and sleep has not been well-studied

Laser Vaporization of Mouth Lesions, an Overview

Lasers are utilized in dentistry as a therapeutic tool or as an auxiliary tool. The major purpose of employing lasers in dentistry is to overcome the difficulties that are currently observed in traditional dental treatment treatments. The laser is used in hard tissue applications such as caries prevention, bleaching, restorative removal and curing, cavity preparation, dentinal hypersensitivity, growth modulation, and diagnostics, whereas soft tissue applications include wound healing, removal of hyperplastic tissue to uncover impacted or partially erupted teeth, photodynamic therapy for malignancies, and photo-stimulation of herpetic lesions. Lasers' capacity to perform minimally invasive operations with minimum patient discomfort has proven effective in the patient delivery system in dentistry practice. The availability of lasers with various wavelengths has produced a surgical panacea, and laser technology has replaced traditional surgical techniques in many oral surgical operations

Importance And Roles Of Clinical Pharmacist, Nurses And Social Workers, Dietitian With The Psychologist In Performing Excellent Patient Care

Professionals in the healthcare industry have a favorable attitude toward psychological cases, as well as the role of clinical pharmacists in the right therapeutic management and education of patients, as well as a vital part in optimizing the dosage of psychotic drugs. On the other hand, there is a potential area for improvement that is connected to the empowerment of the clinical service with privilege and personnel, as well as the elevation of consciousness regarding the growth of the service in ambulatory settings. In addition, the significant roles that social workers and dietitians play in the management of patients, in conjunction with the function that psychologists play
