Introduction: Cognitive deficit is one of the common comorbidity accompanying epilepsy. The present study evaluated the effect of Celastrus paniculatus seed extract on seizure severity and cognitive deficit following the pentylenetetrazole (PTZ)-induced chemical kindling model. Methods: PTZ kindling model was developed by daily administration of the sub-convulsive dose of PTZ 30 mg/kg for four weeks. After four weeks of induction, the following treatment, namely sodium valproic acid (SVA) 200 mg/kg, C. paniculatus 500 mgkg, pergolide 2 mg/kg, C. paniculatus (250 mgkg)+ Pergolide (1 mg/kg), and C. paniculatus (250 mgkg)+ SVA (100 mg/kg) were administered 30 minutes prior to PTZ (30 mg/kg) injection for a period of next 14 days. Neurobehavioral parameters, including superoxide dismutase (SOD), Catalase (CAT), glutathione (GSH), and dopamine levels were assessed and the Morris water maze test (MWM) and Grip strength test (GPS) were performed. Hematoxylin & Eosin (H&E) staining of hippocampal cornu ammonis (CA1), CA2, CA3, dentate gyrus (DG), and frontal cortex was performed. Results: C. paniculatus (500 mg/kg) alone and in combination ( C. paniculatus (250 mgkg)+ pergolide (1 mg/kg) and C. paniculatus (250 mgkg)+ SVA (100 mg/kg)) significantly (p<0.05) reduced the seizure score, mean latency time, and distance traveled in the MWM. However, no significant effect was seen in GPS. Biochemical analysis showed elevated antioxidant markers, namely GSH, CAT, and SOD, and also elevated dopamine levels. C. paniculatus and its combination also significantly (P<0.05) protected against neuronal loss in the hippocampus and frontal cortex evidenced by H&E staining Conclusion: C. paniculatus alone and in combination with other agents may have the potential to treat epilepsy and associated cognitive deficits

Introduction: Theta-Beta Ratio (TBR) has been claimed as a biomarker to diagnose Attention Deficit and Hyperactivity Disorder (ADHD). However, the effectiveness of this index to differentiate between different groups of disorders is still under discussion. The primary purpose was to determine to what extent active TRB can differentiate between children with ADHD and specific Learning Disorder (sLD) as the most common comorbid disorder. Methods: Two groups of school-aged children with sLD (N=15) and ADHD (N=15) were diagnosed through a process of clinical interview and observation. Electroencephalography (EEG) was recorded in both groups during active condition. The implemented cognitive task was the visual continuous performance task (VCPT). TBR in sites of CZ and Fz, and cognitive measures of VCPT were calculated in the aforementioned groups. Results: There was no significant differences in cognitive measures (containing Commission, Omission, Reaction Time, and Variability of Reaction Times) shown in two matched groups of children with sLD and ADHD. According to TBR, two groups demonstrated no significant results in comparison. Conclusion: TBR cannot be considered as a reliable biomarker to differentiate between those groups of psychological disorders that contain primary cognitive deficits and require the allocation of attention and working memory loads.

Introduction: Transcranial direct current stimulation (tDCS) has been studied as an adjunctive treatment option for substance use disorders (SUDs). Alterations in brain structure following SUD may change tDCS-induced electric field (EF) and subsequent responses; however, group-level differences between healthy controls (HC) and participants with SUDs in terms of EF and its association with cortical architecture have not yet been modeled quantitatively. This study provides a methodology for group-level analysis of computational head models to investigate the influence of cortical morphology metrics on EFs. Methods: Whole-brain surface-based morphology was conducted, and cortical thickness, volume, and surface area were compared between participants with cannabis use disorders (CUD) (n=20) and age-matched HC (n=22). Meanwhile, EFs were simulated for bilateral tDCS over the dorsolateral prefrontal cortex. The effects of structural alterations on EF distribution were investigated based on individualized computational head models. Results: Regarding EF, no significant difference was found within the prefrontal cortex; however, EFs were significantly different in left-postcentral and right-superior temporal gyrus (P<0.05) with higher levels of variance in CUD compared to HC [F(39, 43)=5.31, P<0.0001, C=0.95]. Significant differences were observed in cortical area (caudal anterior cingulate and rostral middle frontal), thickness (lateral orbitofrontal), and volume (paracentral and fusiform) between the two groups. Conclusion: Brain morphology and tDCS-induced EFs may be changed following CUD; however, differences between CUD and HCs in EFs do not always overlap with brain areas that show structural alterations. To sufficiently modulate stimulation targets, whether individuals with CUD need different stimulation doses based on tDCS target location should be checked.

Introduction: Schizophrenia is a severe psychotic brain disorder. One of the potential mechanisms underlying this disease may be volumetric changes in some brain regions. The present study aimed to employ magnetic resonance imaging (MRI) to estimate and quantitatively analyze the brain of patients with schizophrenia compared to the controls. Methods: This case-control study was conducted on MRI scans of 20 patients with schizophrenia and 20 healthy controls in Zahedan City, Southeastern Iran. MRIs with 4 mm slice thickness and 5 mm intervals in coronal and sagittal planes were captured. Then, quantitative parameters, including volume and volume density of various brain regions, were estimated in both groups using Cavalieri’s point counting method. Data analyses were performed using the Mann-Whitney U test. Results: The findings of this investigation revealed that volumes of gray matter, hippocampus, and gray/white matter in patients with schizophrenia were significantly lower than the controls (P˂0.05). The volumes of lateral ventricles in patients with schizophrenia (36.60±4.32 mm3) were significantly higher than the healthy individuals (30.10±7.98 mm3). However, there were no statistically significant differences between the two groups regarding the changes in the brain’s total volume, cerebral hemispheres, white matter, brain stem, cerebellum, and corpus callosum (P˃0.05). Conclusion: Volumetric estimations on brain MRI-based stereological technique can be helpful for elucidation of structural changes, following up the treatment trends, and evaluating the therapeutic situations in schizophrenia patients. Volumetric alternations in specific brain areas might be linked to cognitive impairments and the severity of symptoms in patients with schizophrenia. Further research is needed in this regard.

Introduction: Peroxisomes are essential organelles in lipid metabolism. They contain enzymes for β-oxidation of very long-chain fatty acids (VLCFA) that cannot be broken down in mitochondria. Reduced expression in hepatic acyl-CoA oxidase 1 (ACOX1), a peroxisome β-oxidation enzyme, followed by modification of the brain fatty acid profile has been observed in aged rodents. These studies have suggested a potential role for peroxisome β-oxidation in brain aging. This study was designed to examine the effect of hepatic ACOX1 inhibition on brain fatty acid composition and neuronal cell activities of young rats (200-250 g). Methods: A specific ACOX1 inhibitor, 10, 12- tricosadiynoic acid (TDYA), 100 μg/kg (in olive oil) was administered by daily gavage for 25 days in male Wistar rats. The brain fatty acid composition and electrophysiological properties of dentate gyrus granule cells were determined using gas chromatography and whole-cell patch-clamp, respectively. Results: A significant increase in C20, C22, C18:1, C20:1, and a decrease of C18, C24, C20:3n6, and C22:6n3 were found in 10, 12- tricosadiynoic acid (TDYA) treated rats compared to the control group. The results showed that ACOX1 inhibition changes fatty acid composition similar to old rats. ACOX1 inhibition caused hyperpolarization of resting membrane potential, and also reduction of input resistance, action potential duration, and spike firing. Moreover, ACOX1 inhibition increased rheobase current and afterhyperpolarization amplitude in granule cells. Conclusion: The results indicated that systemic inhibition of ACOX1 causes hypo-excitability of neuronal cells. These results provide new evidence on the involvement of peroxisome function and hepatic ACOX1 activity in brain fatty acid profile and the electrophysiological properties of dentate gyrus cells.

Introduction: Muscle biopsy is commonly used to diagnose inflammatory myopathies. We evaluated the ability of muscle ultrasound, a non-invasive and simple tool, to distinguish between healthy subjects and patients with inflammatory myopathy. Methods: This study was conducted on 17 patients recently diagnosed with biopsy inflammatory myopathies (12 dermatomyositis, 5 polymyositis) compared with 17 age- and gender-matched healthy control adults. All patients underwent clinical assessments, including manual muscle testing, hand-held dynamometry, and muscle ultrasound evaluations, including thickness and echo intensity in predefined muscle groups. Results: The disease duration was seven months (interquartile range: 3 to 11 months). Except for the biceps and gastrocnemius, patients’ muscles had significantly higher echo intensity and lower thickness than the control group. The echo intensity sum-score manifested the highest area under the curve compared to the sum-scores of other variables (echo intensity vs manual muscle testing: Area under curves-difference=0.18, P<0.01; echo intensity vs dynamometry: Area under curves-difference=0.14, P=0.02; echo intensity vs thickness: Area under curves-differences-difference=0.25, P<0.01). Conclusion: The echo intensity of muscles differed significantly between healthy individuals and patients with inflammatory myopathies and may serve as a useful diagnostic biomarker.

Published: October 2021

This paper describes in-depth the architecture of a Distributed Cellular framework for Secure Drone Delivery Services with an additional security layer. Delivery Drones are Unmanned aerial vehicles (UAV) that are responsible for the transportation of goods from one place to another place. In the modern world, with several e-commerce platforms, everything is traded, promoted, advertised online. This causes the need to deliver the packages rapidly and within a stipulated period of time. Unmanned aerial vehicles or drones come into the picture to retort the above-mentioned issue. Security nowadays has become a major concern where hackers are diverting the network traffic, hijacking, and crashing the drones. In order to prevent these attacks from taking place, this paper proposes a strong security framework to minimize these attacks from taking place. The proposed architecture has an additional layer of security which covers the two-factor and multi-factor authentication at the delivery spot. There exists an integration of different sensors like Obstacle detection, SOS detection, Facial Recognition, etc. Beyond the security framework, a distributed cellular network is applied to the delivery services to scatter the drones cell-wise and largen the scope to all remote areas.

Bu durumsa, bu özelliklere paralel ve bugün kabul gören üç farklı yaklaşımın ortaya çıkmasına neden olmuştur. Bu bağlamda insan haklarının kaynağı, tanımı, sınırı, işlevi ve yükledikleri gibi bazı sorular; geleneksel, politik ve hukuki olarak adlandırılan yaklaşımlardan birinden yana olan ve kimi zaman bu yaklaşımları bizzat ortaya atan kimi isimler üzerinden cevaplandırılmaya çalışılmaktadır. Bu çalışmanın amacı, uluslararası insan hakları literatüründe yer bulan bu ayrımdaki kimi ayrıştırıcı noktalara ve kilit kavramlara işaret etmek ve söz konusu ayrımda rol oynayan belli başlı görüşleri ulusal literatüre kazandırmaktır. Bu doğrultuda, bu çalışmada, ilgili görüşlere ilişkin kimi eleştirileri ve yaklaşımların birbirleriyle etkileşimini gözlemlemek mümkün olacaktır.

Bu araştırmada etnik restoranlar özelinde hedonik ve faydacı değerlerin tüketici tatmini ve davranışsal niyetler arasındaki ilişkiyi incelemek amaçlanmaktadır. Bu amaç doğrultusunda Türkiye’de yaşayan, en az bir defa etnik restoranda yemek yeme deneyimine sahip olan 393 kişiye anket uygulanmıştır. Verilerin analizinde ölçüm değişkenlerin tutarlılığı ve güvenilirliğinin tespit edilmesi amacıyla doğrulayıcı faktör analizi (DFA) uygulanmıştır. Sonrasında yapısal eşitlik modellemesi (YEM) ile araştırma modelinin yeterliliği ve hipotezlerin geçerliliği test edilmiştir. Elde edilen bulgular incelendiğinde hedonik değer değişkeninin etnik restoranlardaki tüketici tatminini ve davranışsal niyeti istatistiksel olarak anlamlı ve pozitif yönde etkilediği tespit edilmiştir. Faydacı değer değişkeninin ise tüketici tatmini üzerinde anlamlı ve pozitif yönlü bir etkisi bulunurken davranışsal niyet üzerinde anlamlı bir etkisinin bulunmadığı ve her iki değişken üzerinde de hedonik değere göre daha az etkili olduğu tespit edilmiştir. Aynı zamanda tüketici tatmininin hedonik ve faydacı değer ile davranışsal niyetler arasındaki bağlantıda köprü görevi gördüğü, davranışsal niyetler üzerinde pozitif yönlü bir etkisinin olduğu elde edilen bir diğer sonuç olarak dikkat çekmektedir.

English proficiency is considered a frontline skill especially among Humanities and Social Sciences students in the locality. This study was conducted to explore what particular types of code-switching affect the speaking performance among HUMSS. It determined the students’ demographic profile, types of English reading materials, time spent in reading, types of media, time spent in viewing and length exposure to English conversations, frequency of code-switching, and their level of speaking performance. The study used the Spearman rank correlation coefficient to determine the relationships between the demographic profile and the types of code-switching used in the conversation and the relationship of the types of code-switching and the level of speaking performance. The findings revealed that the speaking performance of the respondents is not generally affected by their exposure to English conversation. Nonetheless, it was found out that exposure to English reading materials and media corresponds to students’ fluency in speaking. In addition, using intra-sentential and tag code-switching make students speak fluently in the conversation. With this, it is concluded that intra-sentential and tag code-switching are communicative pedagogical approaches that can be adopted to meet classroom language needs.

Thus, the study highly recommends that the conduct of intervention to students’ low level of speaking performance through the exposure to English reading materials and media, as well as the creation of home libraries and innovative media sources to promote students’ literacy skills.
