Background: Diazinon (DZN) is an organophosphate pesticide, and nowadays this pesticide is mostly used in agriculture. In this study, we analyzed the effects of DZN and vitamin E (Vit E) on apoptosis and the proliferation of germ cells in rat testis.
Materials And Methods: In this experimental study, 30 male Wistar rats were divided into five groups (n=6 per group) consisting of control, sham (received olive oil), experimental group i (60 mg/kg DZN), experimental group ii (60 mg/kg DZN and 200 mg/kg Vit E), and experimental group iii (200 mg/kg Vit E). After six weeks, left testis of rats was removed for the detection of proliferative cell nuclear antigen (PCNA) and terminal deoxynucleotidyl transferase end-labeling (TUNEL).
Results: Compared with the control group, DZN in the experimental group i decreased the number of PCNA-positive cells and increased the number of TUNEL-positive cells (P<0.001). Vit E improved detrimental changes by the decrease in the rate of apoptosis and the increase in the proliferation of testicular germ cells (P<0.001).
Conclusion: Vit E can decrease the number of TUNEL-positive cells and increase the number of PCNA-positive cells by the neutralization of the toxicity caused by DZN in the testicular tissue.

Background: Diabetes with its highly prevalence has become a major contributor to the burden of health care costs worldwide. Recent unequivocal evidence has revealed a bidirectional link between oral health and diabetes. In this study, the effects of the Oral Health Promotion Program (OHPP) on oral hygiene, oral health-related quality of life and glycated haemoglobin (HbA1c) levels in diabetic elderly were examined.

Background: Steroid-induced osteonecrosis of the femoral head (SIONFH) is a universal hip articular disease and is very hard to perceive at an early stage. The understanding of the pathogenesis of SIONFH is still limited, and the identification of efficient diagnostic biomarkers is insufficient. This research aims to recognize and validate the latent exosome-related molecular signature in SIONFH diagnosis by employing bioinformatics to investigate exosome-related mechanisms in SIONFH.

Objectives: This study intended to explore whether the protective effect safflower yellow injection (SYI) on myocardial ischemia-reperfusion (I/R) injury in rats mediated of the NLRP3 inflammasome signaling.
Methods: The I/R model was prepared by ligating the left anterior descending coronary artery for 45 min and then releasing the blood flow for 150 min. 96 male Wistar rats were randomly divided into sham group, I/R group, Hebeishuang group (HBS), SYI high-dose group (I/R + SYI-H), SYI medium-dose group (I/R + SYI-M) and SYI low-dose group (I/R + SYI-L).

Background: Adolescent idiopathic scoliosis, a complex three-dimensional spine deformity, presents a formidable challenge for orthopedic residents in understanding its anatomy and surgical strategies. The aim of this study is to investigate the impact of three-dimensional printing (3DP) models in enhancing the comprehension of adolescent idiopathic scoliosis among orthopedic residents.
Methods: Forty orthopedic residents were randomly divided into two groups, the first group received lectures that were augmented with 3DP models illustrating five cases of adolescent idiopathic scoliosis, along with corresponding X-ray and CT images.
