Öğe AN ANOMALY OF FLEXOR MUSCLES OF THE FIFTH (LITTLE) FINGER OF THE HAND: AN ANATOMICAL CASE REPORT(Hospital Clinicas, Univ Sao Paulo, 2009) Yilmaz, Ali; Bozer, Cueneyt; Ulucam, Enis; Taskinalp, Oguz[Abstract Not Available]Öğe Anthropometric Breast Measurement: A Study of 385 Turkish Female Students(Sage Publications Inc, 2010) Avsar, Dilek K.; Aygit, Ahmet C.; Benlier, Erol; Top, Husamettin; Taskinalp, OguzBackground: Anthropometric measurements and proportions of the human body have made a significant contribution to the science of aesthetic and reconstructive plastic surgery. Objective: The present study was performed to measure anthropometric breast values in Turkish female students and compare them with those of women in other nations. Methods: The study included 385 female undergraduate student volunteers between the ages of 18 and 26 years with no physical or developmental deformity and with a body mass index between 20 and 26. A total of 19 parameters were measured in a standing position. The parameters measured were body weight, height, shoulder width, upper chest width, middle chest width, lower chest width, waist width, hip width, clavicle-nipple length, sternal notch-nipple length, nipple-nipple length, upper arm length, medial mammary radius, lateral mammary radius, nipple-inframammary fold length, nipple diameter, areola diameter, nipple projection, and mammary projection. Breast volume, breast ptosis, and retracted nipple rates were also assessed. Results: The mean breast volume was determined to be 407.2 +/- 263.6 cc. The mean values of the right and left breast volumes were calculated as 415.2 +/- 264.5 cc and 399.1 +/- 265.5 cc, respectively; the right breast volume was significantly greater than the left breast volume (P < .001). The ideal external view of the breasts with equal volume for both sides and no ptosis was observed in 35.1% of the volunteers. The percentage of women with unilateral or bilateral retracted nipple was 2.6%. Conclusions: The results of the present study will help in comparing the anthropometric breast values of young Turkish women with those of women in other countries. They may also be useful either in planning aesthetic and reconstructive breast surgery or in designing breast augmentation accessories and clothing.Öğe Cystic artery anatomies in laparoscopic cholecystectomy and literature review(Bayrakol Medical Publisher, 2022) Turkyilmaz, Zeliha; Hoscoskun, Zeki; Taskinalp, OguzAim: In laparoscopic surgery, knowing the anatomic variations helps to be ready for any possibilities. In this study, it was aimed to evaluate the cystic artery (CA) variations and frequency in patients who underwent laparoscopic cholecystectomy (LC). Material and Methods: The study was carried out by reviewing retrospectively the reports and movies of 100 LC. The positions of the cystic artery and cystic duct relative to Calot's triangle (CT) were determined and the frequency of variation was reviewed. Results: In 82% of our cases, the cystic artery was monitored as a single branch in the CT, whereas two CA were clipped in 12% of cases. In 3 cases in this study, CA went through the caudal of and parallel with the cystic duct, and entered the gall bladder. In one case, the cystic duct passed through the curve formed by the CA. This pattern was named spiral cystic artery. Discussion: The anatomy of the components, which make up a CT has so many diversifications that understanding these variations acts as a key role during LC.Öğe The effect of acute and chronic formaldehyde exposure on learning and memory in male and female rats(Taylor & Francis Ltd, 2023) Aydin, Didem Donmez; Taskinalp, Oguz; Ulucam, Enis; Karadag, Hakan; Ozfidan, Gulnur Kizilay; Topuz, Ruhan; Ersoy, OnurAimFormaldehyde is a chemical that lies behind the various systemical failures in organism. Many products that people use contain formaldehyde. Owing to its tissue fixative properties, scientists who work in life sciences are exposed to this substance more than others. Several studies have shown that formaldehyde affects the CA1 and CA3 regions of the hippocampus, which play crucial roles in memory consolidation. In this study, we aimed to investigate anxiety levels and indicate the short and long term effects of formaldehyde and sex-related differences by exposing formaldehyde to male and female rats.Materials and MethodsFormaldehyde (10 mg/kg) was administered intraperitoneally for 7 days for acute exposure and 30 days for chronic exposure. Cognitive assessment was performed using fear conditioning, elevated plus maze, and Morris water maze tests. TUNEL staining was used to identify apoptosis in the brains obtained after decapitation.ResultsExposure to intraperitoneal formaldehyde does not impair learning and memory in acute and chronic periods and has no effect on depression or anxiety. After acute exposure, apoptosis was observed in the hippocampal CA1 and CA3 regions in males. When the cognitive test results were examined, no differences were found between the experimental and control groups. There was also no significant difference between males and females.Öğe Electron Microscopic Evaluation of the Secretory Mechanisms of Renin from Juxtaglomerular Cells(Soc Chilena Anatomia, 2010) Aktas, Ranan Gulhan; Karabay, Gulten; Taskinalp, Oguz; Kutlu, A. KemalAlthough the structure and the functions of juxtaglomerular cells (JG) have been well defined, there is still a controversy about the secretory mechanisms of renin from these cells. It has been assumed that exocytosis is the main secretory mechanism in these cells in many studies, while others suggest that secretion occurs in a quite different way in these cells. There are several studies suggesting that diacrine secretion, which is very difficult to visualize, might be the other mechanism for secretion of renin. This study is an attempt to find the answers of these questions by identifying the fine structural features of the secretory granules in juxtaglomerular cells. Cyclosporin A (CyA) has been used in the current experimental study since it has already been reported that this drug increases the number of JG cells and stimulates secretion of Renin. Twelve female Sprague-Dawley rats had daily intraperitoneal injections of CyA for ten weeks. Tissue specimens from the kidneys of these animals were examined by electron microscopy. Fine structural characteristics of the secretory granules of juxtaglomerular cells have been examined. Considerable amount of granules, which goes to the exocytotic process, have been observed. Additionally, several cells, which their granules had been secreting their contents in a different way, were found. This was interpreted as the secretion type of diacrine secretion. In conclusion, this in vivo study presents morphologic evidences demonstrating that both exocytosis and diacrine secretion might occur in JG cells. We also had a chance to observe secretory granule probably exhibiting diacrine secretion, which is very difficult to visualize, at electron microscope level for the first time. This report also provides morphologic proof which shows that these two distinct secretory mechanisms might occur simultaneously in the same juxtaglomerular cell.Öğe Some Vertical Proportions of the Face in Turkish Adults(Aves Yayincilik, Ibrahim Kara, 2009) Taskinalp, Oguz; Erdem, NuranObjectives: In this study, we aimed to find the average arithmetical values of some of the vertical proportions of the face in Turkish adult men and women. Patients and Methods: A total of 250 students (1125 females, 125 males) participated in this study. The subjects did not have any physical defects. The average age in females and males were 19.4 +/- 1.0 years and 20.1 +/- 1.4 years respectively. Measurements were made by the same researcher using the same millimetric calipers at the same place and at the same time of day. Results: The height of head, the height of face, the height of superior face and the height of inferior face were measured as 20.0/21.32 cm, 11.15/11.84 cm, 5.09/5.24 cm and 6.21/6.82 cm for females/males respectively. The proportions between these parameters were 55.75%/55.53% for the height of face to the height of head, 25.45%/24.57% for the height of upper face to the height of head, 31.05%/31.98% for the height of lower face to the height of head, 45.65%/44.25% for the height of upper face to the height of face and 55.69%/57.60% for the height of lower face to the height of face, in females/males respectively. Conclusion: We compared the results which are peculiar to Turkish people with the literature. We believe that the results of our study would be useful for other studies on the native Turkish people.Öğe Using temporomandibular joint mobility to predict difficult tracheal intubation(Springer Tokyo, 2011) Sahin, Sevtap Hekimoglu; Yilmaz, Ali; Gunday, Isil; Kargi, Murat; Sut, Necdet; Taskinalp, Oguz; Ulucam, EnisThe aim of this prospective study was to determine the reliability of temporomandibular joint (TMJ) mobility measurements for predicting difficult intubation. To evaluate the accuracy in predicting difficult intubation by TMJ mobility measurement, 762 patients requiring general anesthesia with tracheal intubation for elective surgery were enrolled in this prospective, observational, single-blind study. Maximum mouth opening, right-left jaw excursion, and degrees of protraction were determined with a digital inclinometer. Incisor gap was measured using a vernier caliper during full mouth opening. After induction of anesthesia using a standard protocol, the patient's grade of laryngeal view by Cormack-Lehane classification was documented by an anesthesiologist. We found that the degrees of protraction and incisor gap in the easy intubation group were significantly higher than those in the difficult intubation group. The incisor gap was found to be more sensitive (88.37%) and more specific (95.71%) than protraction degrees (58.14% and 59.76%, respectively). The results revealed that measurements of the incisor gap and degrees of protraction may be useful routine screening tests for preoperative prediction of difficult intubation.
