Abstract: The purpose of this study was to examine the plain anteroposterior radiographs of the hands in Turkish subjects in order to determine the prevalence of sesamoid bones and their distribution. A total of 923 hand radiographs from 459 men and 464 women with a mean age of 43.76±14.8 years (range, 18-85 years) were examined. Two sesamoid bones (ulnar and radial) were always present at the metacarpophalangeal (MCP) joint of the thumb (100%). One sesamoid bone in the thumb interphalangeal (IP) joint was observed in 21.3% of the cases. The prevalence of sesamoid bone of the index and little MCP joint were 36.6% and 53.2% respectively. Sesamoid bones palmar to the MCP joints of the middle finger and ring finger were rare; the incidence for these locations being 1.3% (12 hands) and 0.9% (8 hands), respectively. There were no significant differences between left and right hand digits. The distribution of sesamoid bones in different locations between male and female subjects were statistically similar in 1st IP joint (p=0.530), 4th MCP (p=0.631), 5th MCP (p=0.067) joints. However, the sesamoid bones in 2nd MCP and 3rd MCP joints were statistically more frequent in female subjects (p=0.024 and p=0.018 respectively). The present study represents the first report on the prevalence and distribution of sesamoid bones in the hand in Turkish subjects. The prevalence of sesamoid bones in Turkish population is considerably different from the Africans and Europeans, but rather resembles Mediterranean and Arab populations. El objetivo de este estudio fue examinar radiografías anteroposteriores de manos en sujetos turcos para determinar la prevalencia y distribución de los huesos sesamoideos. Fueron examinadas 923 radiografías de mano, 459 hombres y 464 mujeres, con edad media de 43,76 ± 14,8 a os (rango, 18-85 a os). Dos huesos sesamoideos (ulnar y radial) estuvieron siempre presentes en la articulación metacarpofalángica (MCF) del primer dedo de la mano (100%). Un solo hueso sesamoideo en la articulación interfalángica (IP) del primer dedo de la mano se observó en el 21,3% de los casos. La prevalencia del hueso sesamoideo, índice y articulación MCP fueron fue de 36,6% y 53,2% respectivamente. Los huesos sesamoideos palmares a las articulaciones metacarpofalángica del dedo medio y dedo anular eran poco frecuentes, su incidencia fue 1,3% (12 manos) y 0,9% (8 manos), respectivamente. No hubo diferencias significativas entre los dígitos izquierdos o derechos. La distribución de los huesos sesamoideos en diferentes lugares entre los sujetos de ambos sexos fueron estadísticamente

BMC Gastroenterology , 2011, DOI: 10.1186/1471-230x-11-96
Abstract: Between June 2007 and September 2010, 378 patients (between 16 and 84 years) were recruited prospectively. Of these 378 patients, 226 patients were diagnosed with IBS using the Rome III criteria. 152 control patients were also enrolled who were undergoing colonoscopy for colorectal cancer screening or investigation of anemia. Histopathological abnormalities identified during colonoscopy were compared between the IBS and control groups.The average age of the IBS group was 46.13 ± 14.16 years and and the average age of the control group was 57.01 ± 13.07 years. The prevalence of microscopic colitis (MC) in the diarrhea predominant and the mixed subgroup of IBS patients was 4.32% (7/162) whereas in all IBS patients, the prevalence was 3.09% (7/226). MC was not found in the 152 control cases, (p = 0.045). Lymphocytic colitis was seen in 7 IBS patients, with 1 case in the mixed group and 6 cases in the diarrhea group and there was a significant difference in the frequency of lymphocytic colitis between the IBS subgroups (p < 0.01). Focal active colitis was found in 6.6% (15/226) of the IBS patients and in none of the controls (p < 0.01), and there was no differences between IBS subtypes.Microscopic colitis was more often found in the diarrhea predominant/mixed subgroups of IBS patients and in patients who were older women. In patients who are older woman with non-constipated IBS, it may be reasonable to perform a biopsy to screen for microscopic colitis. Focal active colitis was significantly increased in patients with IBS compared to controls.Irritable bowel syndrome (IBS) is a functional bowel disorder of unknown etiology without a curative treatment. In addition to abdominal discomfort and pain, relief from discomfort upon defecation and/or abdominal pain is associated with a change in the frequency of defecation and/or in the form of the feces [1]. The prevalence of IBS varies in different populations. The prevalence of IBS in Turkey was found 7.4-19.1% with female p

Advances in Chemical Engineering and Science (ACES) , 2017, DOI: 10.4236/aces.2017.71006
Abstract: The undergraduate chemistry programs of different universities across the world show clearly that nuclear chemistry education doesn’t have a permanent status in chemistry curricula like classical sub-branches of chemistry which means like organic, inorganic, analytical, physical, and biochemistry. Before starting the evaluation of the status of nuclear chemistry education, first of all, nuclear chemistry should correctly be defined and its position in chemistry education programs should correctly be determined. In addition, a confusion of terminology or at least, a terminological turbulence exists in this branch of chemistry about the use of terms such as nuclear chemistry, radiochemistry, nuclear and radiochemistry. Also, the scopes of the expressions used in this field such as radiochemistry, radiation chemistry, radiopharmaceutical chemistry, etc. should be exactly defined and the realtions between them should be clearly understood. Breifly, nuclear chemistry may be difined as a large umbrella which covers all chemical studies related to radioactive materials and nuclear radiation including the fine sub-branches such as radiochemistry, radiation chemistry, radioanalytical chemistry, radiopharmaceutical chemistry, environmental radiochemistry. If these are not done, the educational problems in nuclear chemistry could not be correctly investigated and the remedies could not be correctly determined.

Open Journal of Applied Sciences (OJAppS) , 2013, DOI: 10.4236/ojapps.2013.37051
Abstract:

The rapid increase in the use of plastic materials in the recent years led to the accumulation of excessive amounts of plastic waste. The so-called thermoplastics such as PE, PP, PS, PVC and PET as well as materials that are derived from these are the type of plastic that is most used and consequently creates most of the waste. In this study, the original and waste forms of PE and PP plastic types have been chosen for thermal and catalytic degradation. As process parameter, 410oC - 450oC temperature interval and 600 mL/min constant flow rate nitrogen gas have been chosen as the carrier gas and the reaction time was considered to be 90 minutes for all experiments. Liquid products collected in experiments were separated by means of fractioned distillation process. For purposes of determining product distribution, the fractions, which were separated by distillation, were diluted in an appropriate solution for analysis of GC/MS. In the study conducted, it has been observed that the liquid product distribution obtained mainly consists of a mixture of saturated and unsaturated (heptane, heptane, octane, nonane, dodecane, etc.) hydrocarbons.

Abstract: Situs inversus totalis (SIT) is a congenital anomaly characterized by complete transposition of abdominal and thoracic organs. As a birth defect in newborn infants, it has an estimated incidence of 1/15000 to 10000 cases in live births, with a male/female ratio of 3:2. Generally, this rare anomaly is diagnosed incidentally during thoracic and abdominal imaging. The cause of situs inversus (SI) is unknown. More than one genetic mutations including gene mutations which cause ciliopathy and cystic renal diseases were implicated in etiopathogenesis [1]. SIT is associated with various gastrointestinal abnormalities. In the current literature, development of intestinal ischemia due to intestinal malrotation, and also acute appendicitis and liver transplantation due to juvenile biliary atresia were reported [2-4]. However, there is no data for the development of secondary biliary cirrhosis (SBC) due to extrahepatic cholestasis in a patient with SIT. We here presented a case of SIT with SBC who referred to our clinic due to extrahepatic cholestasis.A 58-year-old female patient, who complained of icterus appearing in the last 6-7 months, along with the symptoms of fatigue and loss of appetite continued for 2-3 years, was referred to our clinic. According to her medical history, she had been referred to a clinic because of abdominal pain in the left lower quadrant and examined due to acute abdominal pain when she was 6 years old. She had undergone a surgical operation due to acute appendicitis located in the left lower quadrant and the SIT was diagnosed on those days. Furthermore, frequently recurrent upper respiratory tract infections, hypertension and a previous cholecystectomy (19 years ago) were found in her medical history. The patient was a smoker (26 packs/year) but she did not consume alcohol. In detailed personal history, she did not have any hepatotoxic drug usage in past three months. In her physical examination, icteric appearance, moderate hepatomegaly and kyphos

Journal of Power and Energy Engineering (JPEE) , 2015, DOI: 10.4236/jpee.2015.34060
Abstract:

The aim of this study is analyzed in detail for better understanding of energy and power of an aero-engine. In this regard, this study presents energy equations were applied to the turbofan engine components. The engine has a thrust range of 82 to 109 kN. It consists of fan, axial low pressure compressor (LPC), axial high pressure compressor (HPC), an annular combustion chamber, high-pressure turbine (HPT) and low pressure turbine (LPT). The results show that power of the engine flow approaches a maximum value to be 82.85 MW in the combustor outlet, while minimum power is observed at LPC inlet with the value of 1.37 MW. Furthermore, important parameters of the engine are also analyzed from reverse-engineering method. It is expected that results of this study will be beneficial of power, cogeneration and aero-propulsive generation systems in similar environment.

Murat Turan, Ramazan Mammadov
Pharmacology & Pharmacy (PP) , 2018, DOI: 10.4236/pp.2018.94008
Abstract: In this study, antioxidant, cytotoxic, larvicidal, antimicrobial and anthelmintic effects and phenolic contents of ethanol, methanol and acetone extracts of leaf and tuber parts of Cyclamen alpinum were investigated. DPPH, ABTS, β-carotene assays were carried out in antioxidant activity and total phenolic and flavonoid contents were tested in determination assay. 9 phenolic contents were determined by HPLC. Artemia salina was used in the cytotoxic effect. Larvicidal effect was investigated against Culex pipiens. Disc diffusion method was used in antimicrobial effect. The tuber part was found to be more toxic than the leaf part in the anthelmintic activity assay. The highest value obtained from the antioxidant activity experiment was observed with value of 86.73 ± 0.16 (%) in DPPH assay. The lowest LC50 value in larvicidal effect was determined 0.151 mg/mL after 72 hours. Consequently, there is need for further studies on the Cyclamen alpinum, which has the ability to fight against diseases such as cancer, cardiovascular diseases, etc.

Gradient Observability for Semilinear Hyperbolic Systems: Sectorial Approach  [PDF]
Adil Khazari, Ali Boutoulout
Intelligent Control and Automation (ICA) , 2014, DOI: 10.4236/ica.2014.53019
Abstract:

The aim of this work is to study the notion of the gradient observability on a subregion ω of the evolution domain Ω for a class of semilinear hyperbolic systems. We show, under some hypothesis, that the gradient reconstruction is achieved following sectorial approach combined with fixed point techniques. The obtained results lead to an algorithm which can be implemented numerically.
