Investigatıon of the effect of weight loss after laparoscopic sleeve gastrectomy on cobb angle, waist and back pain: a prospective study.

Background: In many studies, it has been stated that obesity causes severe increases in the risks of disc degeneration, vertebral fracture, low back, and back pain. One of the most effective treatment options for obesity is bariatric surgery.

Objectives: In this study, the effect of weight loss on these parameters was investigated by evaluating the Cobb angle, low back, and back pain.

Comparison of the cystocholedochal angle in patients with choledocholithiasis and only cholelithiasis.

This study aims to evaluate the relation between the cystocholedochal angle (SCA) and choledocholithiasis. The data of 3.350 patients were reviewed retrospectively and a total of 628 patients who met the criteria were included in the study.

Differentiation of claustrum resting-state functional connectivity in healthy aging, Alzheimer's disease, and Parkinson's disease.

The claustrum is a sheet-like of telencephalic gray matter structure whose function is poorly understood. The claustrum is considered a multimodal computing network due to its reciprocal connections with almost all cortical areas as well as subcortical structures. Although the claustrum has been involved in several neurodegenerative diseases, specific changes in connections of the claustrum remain unclear in Alzheimer's disease (AD), and Parkinson's disease (PD).

The Comparison of Piriform Aperture, Paranasal Sinuses, and Cranial Dimensions.

Objective: Piriform aperture, paranasal sinuses, and the cranium dimensions were compared with each other and we investigated the alterations depending on the age and gender in these structures. Before the endoscopic sinus surgery, anatomic variations in sinusoidal region and the occurring differences should be considered. The detection of these variations plays important roles in the prevention of complications which may happen in surgery or in obtaining a successful surgical result.

Melatonin prevents cyclosporine-induced hepatotoxicity in rats.

Objectives: Cyclosporine A (CsA) is a widely used immunosuppressive agent that is implicated in the formation of free oxygen radicals. Melatonin is known to be a free radical scavenger and an antioxidant agent. This study was designed to investigate the effects of melatonin on CsA-induced liver damage by histopathological examination.

[Assessment of the vulnerability of the proximal tibiofibular joint to injury during osteotomies].

Objectives: We evaluated the dimensions and anatomic localization of the proximal tibiofibular joint (PTFJ) in human cadaver and amputated knees. In addition, we assessed the relation between the osteotomy line and the PTFJ and its vulnerability to injury on radiographs of patients after proximal tibial medial open wedge osteotomy (PT-MOWO).

Methods: In the first phase, dimensions of the tibial part of the PTFJ lying between the lateral tibial condyle and the fibular head were measured by digital calipers in six human cadaver and six fresh amputed tibiae (4 females, 8 males; mean age 57 years) to evaluate the relation between the tibial surface of the PTFJ and the posterior part of the lateral tibial plateau.
