Effect of dapagliflozin against NAFLD and dyslipidemia in type 2 diabetic albino rats: possible underlying mechanisms.

OBJECTIVE: The aim was to investigate the effect of dapagliflozin on non-alcoholic fatty liver disease and dyslipidemia in type 2 diabetic rats by studying the histopathological structure of the liver and detecting possible underlying mechanisms for this impact by evaluating the potential anti-inflammatory action of dapagliflozin. MATERIALS AND METHODS: 100 albino rats were used in this work and divided into five equal groups: group I (Control group), group II (Control diabetic group), group III (was administered dapagliflozin, 0.75 mg/kg, p.o.), group IV (was administered dapagliflozin, 1.5 mg/kg, p.o.), and group V (was administered dapagliflozin, 3 mg/kg, p.o.). RESULTS: In our study, the total body weight, liver weight, liver index, blood glucose level, insulin level, insulin resistance, total cholesterol, triglycerides, liver enzymes, IL-1 ß, and MDA were significantly higher in the control diabetic group than the normal group. The dapagliflozin reduced all the above variables significantly in a dose-dependent manner compared to the control diabetic group (p-value = 0.001 for all). CONCLUSIONS: Dapagliflozin may be a promising novel treatment strategy for treating T2DM-related non-alcoholic fatty liver disease (NAFLD), and dyslipidemia where it possesses anti-oxidative, anti-inflammatory and anti-dyslipidemic effects.

Immediate dental implant placement with a horizontal gap more than two millimetres: a randomized clinical trial.

The purpose of this study was to evaluate the horizontal dimensional changes in buccal alveolar bone immediately after dental implant placement in the upper premolar area with horizontal gaps >2mm. A total of 48 patients were enrolled in this randomized clinical trial and were randomly assigned to one of three groups. Group I (flap with graft; n=16) patients received an immediate implant with bone graft, membrane, and primary flap closure. Group II (flap without graft; n=16) patients received an immediate implant with primary flap closure only. Group III (flapless without graft; n=16) patients received an immediate implant without graft, membrane, or primary closure. Cone beam computed tomography (CBCT) scans were obtained preoperatively, immediately after implant placement, and at 6 months postoperative to evaluate horizontal dimensional changes in the buccal alveolar bone. Pain intensity was measured using a numerical rating scale. CBCT examinations revealed that bone had filled the horizontal gap in all three groups. Group II showed the greatest horizontal dimensional changes in the buccal alveolar bone, followed by group I. The least amount of change was recorded for group III. Furthermore, significantly less postoperative pain was recorded in group III when compared to the other groups. Short-term results suggest that the 'flapless without graft' technique shows similar results to the 'flap with graft technique' for immediate implant placement in the maxillary premolar extraction site with a horizontal gap >2mm, when the bone plate is intact.
