Absence of Frontal Sinus in Turkish Individuals
(Yonsei University College of Medicine, 2003) Aydinlioǧlu, A.; Kavakli, A.; Erdem, S.
The frontal sinus has been used for personal identification since the early part of the 20th century as a result of its tremendous interindividual variation. The frontal sinus is present in approximately 90% of adults. However, some populations have a higher proportion of people without a frontal sinus. This study investigated the frequency of the absence of frontal sinuses in Turkish individuals. The present study was performed retrospectively on the CT scans of the paranasal sinuses in the axial and coronal planes from a series of 1200 cases. A bilateral absence and a unilateral absence of sinuses were found in 3.8% and 4.8% of cases, respectively. The clinical significance of the frontal sinuses and their absence are also discussed.
The Beneficial Effect of Electro Acupuncture on Obesity May Be Associated With Irisin, Nesfatin-L and Preptin Levels
(Cognizant Communication Corporation, 2019) Ercan, Z.; Deniz, G.; Caf, F.; Algul, S.; Gazioglu, A.; Kavakli, A.
The action mechanism of acupuncture, one of the alternative methods used in obesity treatment, is unknown. The purpose of this study was to investigate the effect of electroacupuncture on weight loss and whether acupuncture treatment can change circulating levels of irisin, nesfatin-l and preptin, which have been discovered in recent years and plays an important role in nutrition and energy metabolism. Irisin, a newly discovered myokine, is associated with increased energy consumption and has a potential role in obesity. Preptin, present in islet b-cells of pancreas and associated with the carbohydrate metabolism, nesfatin- 1 is an anorexogenic peptide composed of 82 amino acids and regulates food intake by modulating neuropeptides in feeding centers in the brain. These three new hormones regulate energy intake and expenditure and preserve energy homeostasis and composition. In this study 4 weeks old Sprague Dawley male rats (n=16) were randomly divided into 2 groups which were the control (C): normal diet and obese (O): high fat diet (HFD) groups. After 16 weeks which obesity was developed, electroacupuncture (EA) was performed to rats once in every second days for 3 times weekly for four consecutive weeks. EA was applied bilaterally to Zusanli (ST36), Bai Hui (Du20), He Gu (Li4), Tianshu (ST25) and Sanyinjiao (SP6) acupoints in animals to both groups. Blood was collected before and after EA and serum irisin, nesfatin-l and preptin levels were analyzed by ELISA (Enzyme-Induced- Immunosorbent Analysis) method. After four week EA treatment, there was sginificant decrease of the average body weight in both groups rats. There were increases in the serum nesfatin-l and preptin levels in the both groups after acupuncture. A decrease was observed in the irisin levels in obese group, but an increase in the control group. These findings suggest that electroacupuncture may help to weight loss due to its effects on some important metabolic hormones such as irisin, nesfatin-l and preptin only for a few weeks. It is thought that the changes of these hormones levels may playa role in beneficial effect of acupuncture used in the treatment of human obesity. The application of EA in the treatment of obesity is very effective, which may have led to weight loss by altering these hormone levels in obese people. Copyright © 2019 Cognizant Communication Corp.
Effects of Caffeic Acid Phenethyl Ester on Cerebral Cortex: Structural Changes Resulting From Middle Cerebral Artery Ischemia Reperfusion
(Dustri-Verlag Dr. Karl Feistle, 2007) Cengiz, N.; Colakoglu, N.; Kavakli, A.; Sahna, E.; Parlakpinar, H.; Acet, A.
Overproduction of free radicals is important in the pathogenesis of the cerebral damage induced by ischemia reperfusion. Caffeic acid phenethyl ester, an active component of propolis extract, exhibits antioxidant properties. The study was carried out in 16 male Wistar albino rats, divided into two groups: ischemia reperfusion and ischemia reperfusion with caffeic acid phenethyl ester. The middle cerebral artery was occluded for 60 min with an intraluminal suture, followed by 24-h reperfusion. In this study, widespread infarcted areas, red neurons (eosinophilic degeneration), pyknotic cells, vacuolization and neuroglial cell infiltration were observed in the cerebral cortex in the ischemia reperfusion group. In the caffeic acid phenethyl ester group, slightly infarcted areas were observed and neuroglial cell infiltration was not determined. Congestion of choroid plexus and pia mater was found more severe in the ischemia reperfusion group than in the caffeic acid phenethyl ester group. In the caffeic acid group, neuroglial cell activation was rare. Vacuolization, an indication of brain edema, was prevented by caffeic acid phenethyl ester. In the present study, we showed that pre-treatment with a single i.p. injection of caffeic acid phenethyl ester at 50 μM/kg dose reduced the structural changes. ©2007 Dustri-Verlag Dr. K. Feistle.
Local Differences in the Position of the Mental Foramen
(2008) Yeşilyurt, H.; Aydinlioǧlu, A.; Kavakli, A.; Ekinci, N.; Eroǧlu, C.; Hacialioǧullari, M.; Diyarbakirli, S.
The mental foramen has been reported to vary in position in different ethnic groups. Repeated failures during injections and operative procedures involving the mental foramen suggest the presence of local differences in a given population. The aim of the present study was to investigate possible local differences of the mental foramen in Eastern Anatolian individuals in the Turkish population. The present investigation is based on the examination of 70 adult mandibles. The study consisted of three measurements, to include the relations of the mental foramen to the following: 1) the lower teeth; 2) the body of mandible; 3) the mandibular symphysis and posterior border of the remus of the mandible. The most common position of the foramen was in line with the longitudinal axis of the second premolar tooth (relation IV), at the midpoint of the mandibular body height and at 1/3.5 of the distance from the mandibular symphysis to the posterior border of the ramus. Local differences of the mental foramen may occur in a population. Prior to surgery knowledge of the most common location of the foramen peculiar to a local population may enable effective mental block anaesthesia to be provided. Copyright © 2008 Via Medica.
