Pathological yawning in patients with acute middle cerebral artery infarction: Prognostic significance and association with the infarct location

Background: Pathological yawning is a compulsive, frequent, repetitive yawning triggered by a specific reason besides fatigue or boredom. It may be related to iatrogenic, neurologic, psychiatric, gastrointestinal, or metabolic disorders. Moreover, it could also be seen in the course of an ischemic stroke. Aims: To determine whether pathological yawning is a prognostic marker of middle cerebral artery stroke and evaluate its relationship with the infarct location. Study Design: Cross-sectional study. Methods: We examined 161 patients with acute middle cerebral artery stroke, consecutively admitted to emergency department. Demographic information, stroke risk factors, stroke type according to Trial of Org 10172 in Acute Stroke Treatment classification, blood oxygen saturation, body temperature, blood pressure, heart rate, glucose levels, daytime of stroke onset, National Institutes of Health Stroke Scale score (National Institutes of Health Stroke Scale score, at admission and 24 h), modified Rankin scale (at 3 months), and infarct locations were documented. Pathological yawning was defined as ?3 yawns/15 min. All patients were observed for 6 hours to detect pathological yawning. National Institutes of Health Stroke Scale score >10 was determined as severe stroke. The correlation between the presence of pathological yawning and stroke severity, infarct location, and the short-and long-term outcomes of the patients were evaluated. Results: Sixty-nine (42.9%) patients had pathological yawning and 112 (69.6%) had cortical infarcts. Insular and opercular infarcts were detected in 65 (40.4%) and 54 (33.5%) patients, respectively. Pathological yawning was more frequently observed in patients with cortical, insular, and opercular infarcts (p<0.05). Pathological yawning was related to higher National Institutes of Health Stroke Scale scores. Patients with severe stroke (National Institutes of Health Stroke Scale score ?10) presented with more pathological yawning than those with mild to moderate strokes (p<0.05). The clinical outcomes and mortality rates showed no significant relationship with the occurrence of pathological yawning. Conclusion: Pathological yawning in middle cerebral artery stroke was associated with stroke severity, presence of cortical involvement, and insular and opercular infarcts. However, no association was found with long-term outcome and mortality. ©Copyright 2020 by Trakya University Faculty of Medicine / The Balkan Medical Journal published by Galenos Publishing House

Microwave-assisted synthesis, characterizations, antimicrobial activities, and DFT studies on some pyridine derived Schiff base

This study reports a joint experimental, theoretical and microbiological investigation on the (E)-N,N-dimethyl-4-((pyridine-2-ylmethylene)amino)aniline (5), (E)-N,N-dimethyl-4-((pyridine-4-ylmethylene)amino)aniline (6) and (E)-N,N-dimethyl-4-((pyridine-3-ylmethylene)amino)aniline (7). These compounds were synthesized with microwave method and their structures characterized by FT-IR, 1H-NMR, 13C-NMR, and elemental analysis tecniques. In the theoretical studies, torsional barriers analysis, ground state structure, Fourier Transform Infrared spectra (FT-IR), and Nuclear Magnetic Resonance spectra (NMR) of 5, 6, and, 7 were calculated by Density Functional Theory (DFT) computations. The conformers obtained from the torsional barrier scanning were optimized by B3LYP/6-31G(d,p) level. The harmonic vibrational frequencies, potential energy distribution (PED), infrared intensities, and NMR chemical shifts of the most stable conformers were determined using the B3LYP/6-311++G(d,p). Theoretically, predicted spectral data were compared with experimental results. Antimicrobial studies of the synthesized compounds were performed against various microbial strains. Antimicrobial activities of 5, 6, and, 7 were tested against selected bacteria and yeast through minimum inhibitory concentration (MIC) and diffusion method. Compound 7 was found to be the most active against bacteria and yeast, while compound 5 was found to be moderately active. Compounds 6 (against S. aureus and C. albicans) and, 7 were found to have a very high minimum inhibitory concentration, ranging between 1.95 and 7.81 g/mL (against P. aeruginosa and E. coli). Compounds (6 and 7) showed zone of inhibition values in the range of 10–20 mm against other bacteria except L. monocytogenes and S. thyphimurium. © 2022 Elsevier B.V

Correlation of TEM data with confined phonons to determine strain and size of Ge nanocrystals embedded in SixNy matrix

Models that use phonon confinement fail to provide consistent results for nanocrystal sizes in differing dielectric matrices due to varying stress experienced by nanocrystals in different dielectric environments. In cases where direct measurement of stress is difficult, the possibility of stress saturation as a function of size opens up a window for the use of phonon confinement to determine size. We report on a test of this possibility in Ge: SixNy system. Ge nanocrystals (NCs) embedded in silicon nitride matrix have been fabricated using plasma enhanced chemical vapor deposition (PECVD) followed by post annealing in Ar ambient. Nanocrystal size dependence of Raman spectra was studied taking into account associated stress and an improved phonon confinement approach. Our analysis show same stress for NCs which have sizes below 7.0 nm allowing the use of phonon confinement to determine the nanocrystal size. The results are compared with TEM data and good agreement is observed. © 2017 Elsevier Lt

Examination Of Mobbing Behaviors Experıenced By The Personnel Working At Youth Services And Provincial Directorates Of Sports,

The purpose of this research is to examine mobbing behaviors experienced by the personnel working at Youth Services and Provincial Directorates of Sports according to their sex, age, marital status, occupational seniority and graduated school. The research is such made by using general scanning model. The personnel working at the district and provincial offices of Youth Services and General Directorate of Sports constitute the population of the research and 325 personnel working at Youth Services and Provincial Directorates of Sports selected randomly from the population in 25 provinces constitute the sample of the research. The data regarding mobbing actions experienced by the personnel was collected by using “Negative Acts Questionnaire” (NAQ). “Negative Acts Questionnaire” (NAQ) was developed by Einarsen and Raknes (1) and adapted to Turkish by Cemaloglu (2). Cronbach Alpha reliability coefficient of the subjected scale was re-calculated and determined to be 0,89. During the analysis of data frequency (f), percentage distribution (%), arithmetic average (x), -t and F tests were used and data were analyzed by means of SPSS 15,00 packaged software. Significance level was accepted as 0.5 in order to determine whether a difference exists between the variants applied in the questionnaire. As a result of our research it was determined that 44% of the personnel working in GHSİM (Youth Services and General Directorate of Sports) suffered mobbing behaviors. When the questionnaire results are analyzed it is seen that women exposed more mobbing behaviors comparing to men, those between 21-30 age group exposed more mobbing behaviors comparing to other age groups, those married exposed more mobbing behaviors comparing to single and divorced, those having 1-10 years of seniority exposed more mobbing behaviors comparing to those having other seniorities, those having bachelor’s degree and associate degree exposed to more mobbing behaviors comparing to other graduates. It was determined that there is a significant difference between mobbing experiencing levels according to sex, age, occupational seniority and graduated school of the GHSİM personnel and no significant difference according to marital status variant

Katılımcıların çoğunlukla kendi spor dallarını daha iyi konuma getirebilmek için sosyal ve kültürel aktivitelerden çok sportif serbest zaman aktivitelerine yöneldikleri görülmüştür. Ayrıca üniversite yöneticilerinin, bireylerin kişisel gelişiminde ve sosyalleşmesinde önemli bir yeri olan serbest zaman etkinliklerini düzenleme ve öğrencileri yönlendirmede yetersiz kaldıkları sonucuna ulaşılmıştır

Researching Of Ranking Handball Referees' Job Satisfaction Levels In Terms Of Some Parameters,

This research has been conducted in order to determine the job satisfaction levels of the ranking referees in terms of some parameters (sex, age, marital status, income states, other profession, and refereeing period). This research is a descriptive study towards the review of job satisfaction levels of Handball ranking referees. Referees take charge in 2010-11 season in Turkish leagues constitute the population of the research. Accordingly 107 Ranking referees under Turkish Handball Federation constitute the sample of the research. SPSS package program was used for the statistical analyses. Measuring tool is constituted of two sections. In first section a test directed towards to determine the demographical features of the referees while in second section “Minnesota job satisfaction scale” was used. Validity and reliability studies were made (cronbach alpha =0.70). It was determined that statistically there is not a significant gap between the job satisfaction levels of the referees according to their sex, marital status, ranking position, refereeing periods and income status; and statistically there is a significant gap between their job satisfaction levels according to their ages. Increase of job satisfaction with the increase of age, increase of the experience, awards, rise of refereeing ranking and coalescence with the job are considered to be the factors for the existence of such difference. Income levels of the majority of the referees are seen to be at intermediate level
