Fully Automated Morphological Analysis Of Patients With Obstructive Sleep Apnea, Oktay Alğin, Burak Akin, Gökhan Ocakoğlu, Evri̇m Özmen
Turkish Journal of Medical Sciences
Background/aim: Obstructive sleep apnea syndrome (OSAS) is a disease characterized by episodic hypoxia. We aimed to use the Freesurfer program for global evaluation of morphological changes in OSAS patients. Materials and methods: Three-dimensional T1-weighted images were obtained, and intracranial morphology was assessed in 18 patients with OSAS and 20 controls. Results of the volume and the cortical thickness analyses of both groups were compared statistically. Results: The total cortical, left-right hemispheres gray matter (GM), corpus callosum, and total GM volumes were lower in OSAS patients when compared with the control group (P < 0.001). The average cortical thickness was lower in OSAS patients bilaterally in pars orbitalis, paracentral, rostral middle frontal, middle frontal, orbital, and superior frontal gyri when compared with the control group (P < 0.05). Furthermore, the volume and average cortical thickness of multiple anatomic regions, apart from the brain parts mentioned above, were decreased unilaterally (e.g., hippocampus, cingulum, putamen, thalamus) in OSAS patients (P < 0.05). Conclusion: Multiple morphologic changes occur in the cerebral structures of OSAS patients due to intermittent ischemia episodes. Detection of those areas with Freesurfer is easier. New studies with large series would be needed for these subjects.

Free Radical-Induced Nephrotoxicity Following Repeated Oral Exposureto Chlorpyrifos Alone And In Conjunction With Fluoride In Rats, Naseer Baba, Rajinder Raina, Pawan Verma, Mudasir Sultana
Turkish Journal of Medical Sciences
Background/aim: Chronic renal disorder is becoming a major health problem worldwide. The purpose of the present study was to investigate alterations in the renal antioxidant system in rats induced by repeated exposure to chlorpyrifos (CPF) alone and in conjunction with fluoride. Materials and methods: Wistar rats were randomly allocated to seven groups, each consisting of six rats, and were subjected to different treatment regiments for 28 days. Results: Significant increases (P < 0.05) in plasma protein, blood urea nitrogen, and creatinine levels indicated alterations in renal functions on repeated exposure to CPF or fluoride; moreover, these changes were more pronounced in animals exposed to both toxicants concurrently. A significant increase (P < 0.05) in malondialdehyde levels and decreases in superoxide dismutase, catalase, and glutathione peroxidase activities in renal tissue were noted, indicating renal damage on exposure to CPF, fluoride, or the combination of those. Conclusion: Our observations suggested that the concurrent exposure to CPF and fluoride increased the extent of renal damage. These findings indicate that this damage is due to increased free radical formation and a reduced function of the antioxidant system in renal tissue. Thus, the application of CPF as an insecticide should be reduced in areas where the fluoride levels in ground waters are high in order to minimize renal damage in exposed populations.

The present study investigated the effect of autograft and hyaluronic acid (HA) in terms of clinical, radiological, and histopathological aspects on the healing of experimentally induced bone defects. The animals (n = 42) were assorted into 3 groups. After general anesthesia, a 3-mm standard defect was formed from the tibia of the experimental animals. The defects in Group I (n = 14) were left blank. Cancellous grafts in the proximal tibia were collected using a small curette to fill the defects in Group II (n = 14). The defects in Group III (n = 14) were filled by mixing with …

In this study, we developed the seed-specifically regulated autoexcision system based on Cre/loxP site-specific recombination for coelimination of nptII and cre genes from transgenic plants. To accomplish this, a seed-specific gene promoter, BcNA1, from Brassica napus was used to drive conditional expression of recombinase. NptII and recombinase cassettes were placed between two directly repeated loxP sites. The loxP-flanked DNA was located between the SP-DDEE synthetic pathogen inducible promoter and pr??omoterless β-glucuronidase (Gus) gene, as a model gene of interest. Upon seed-specific expression of cre recombinase, the excision event would eliminate loxP-flanked DNA and bring the gus reporter gene under the …

Dental pulp tissue contains stem cells that can be isolated and used for regenerative medicine in tooth restoration or autologous transplantation. The aim of this study was to observe the mineralization and gene expression in dental pulp cells (DPCs) following treatment with snail mucus. Snail mucus was collected from adult Achatina fulica and processed as a dry powder by the freeze-drying technique. The mucus powder was dissolved in a culture medium at a concentration of 15 μg/mL. DPCs were prepared by the outgrowth technique and cultured in a 6-well plate at a density of 5 × 104 cells per well. …

This study was designed to evaluate the in vitro chondrogenic differentiation potential of equine adipose tissue-derived mesenchymal stem cells (AT-MSCs) in response to different culture conditions. Fat tissue cells after collection were cultured in optimized conditions until passage 3 (P3). P3 cells were cultured as micropellets under different chondrogenic conditions for 21 days in 5 groups: basic medium as a control, basic chondrogenic medium (BCM), BCM supplemented with transforming growth factor beta 3 (TGF-β3; 10 ng/mL), BCM supplemented with bone morphogenetic protein 6 (BMP-6; 10 ng/mL), and BCM supplemented with both TGF-β3 and BMP-6. The growth rate of pellets was …

A fiber optic biosensor was constructed from Pleurotus ostreatus laccase for the detection of polyphenolic compounds. Laccase was immobilized on the surface of the commercially available fiber optic oxygen sensor spots by using 3-aminopropylsilanetriol, glutaraldehyde, and amino-modified carboxycellulose. A diffusion layer containing tetramethyl orthosilicate (TMOS), trimethoxymethylsilane (Tri-MOS), and polyvinyl alcohol (PVA) was added to the immobilized laccase layer. The consumption of oxygen as a result of laccase activity was monitored using a fiber optical measuring setup with catechol as a model substrate. The optimal enzyme amount was determined as 1.5 mg per 50 µL of enzyme layer mixture, and with …
