Chronic wasting disease (CWD) is caused by abnormal deleterious prion protein (PrPSc), and transmissible spongiform encephalopathy occurs in the Cervidae family. In recent studies, the susceptibility of prion disease has been affected by polymorphisms of the prion gene family. SKI606 However, the study of the prion-related protein gene (PRNT) is rare, and the DNA sequence of this gene was not fully reported in all Cervidae families. In the present study, we amplified and first identified PRNT DNA sequences in the Cervidae family, including red deer, elk, sika deer and Korean water deer, using polymerase chain reaction (PCR). We aligned nucleotide sequences of the PRNT gene and the amino acid sequences of prion-related protein (Prt) protein among several species. In addition, we performed phylogenetic analysis to measure the evolutionary relationships of the PRNT gene in the Cervidae family. Furthermore, we performed homology modeling of the Prt protein using SWISS-MODEL and compared the structure of Prt protein between sheep and the Cervidae family using the Swiss-PdbViewer program. We obtained much longer PRNT sequences of red deer compared to the PRNT gene sequence registered in GenBank. Korean water deer denoted more close evolutionary distances with goats and cattle than the Cervidae family. We found 6 Cervidae family-specific amino acids by the alignment of Prt amino acid sequences. There are significantly different distributions of hydrogen bonds and the atomic distance of the N-terminal tail and C-terminal tail between sheep and the Cervidae family. link2 We also detected the mRNA expression of PRNT gene in 3 tissues investigated. To our knowledge, this report is the first genetic study of the PRNT gene in the Cervidae family.Mercuric chloride (MC) is a complex substance which is capable to produce free radicals. Middle Eastern Phoenix dactylifera (MEPD) is a flowering plant of palm family with potent antioxidant feature. Due to the increasing use of herbs in medicine, this study was designed to assess the effects of MEPD and MC on inflammatory apoptogenic, oxidative and histomorphometric alterations in liver. Sixty-four male rats were assigned to 8 groups including control groups (normal group and MC (50 mg/kg)), MEPD groups (30, 90, 270 mg/kg) and MC + MEPD treated groups. All experimental groups were treated intraperitoneally and orally daily for 5 weeks. The relative expression level of apoptotic genes (p53, Bcl2 and Bax) and hepatocyte apoptotic index were analyzed. Also, Nitrite oxide (NO), lipid peroxidation (LP), Ferric Reducing Ability of Plasma (FRAP) assays were conducted to assess the antioxidant levels. Cytokines involved in inflammation, hepatic enzymes and histomorphometric parameters (hepatocytes diameter (HD) and central hepatic vein (CHV)) were evaluated. All factors showed incremental trends following MC administration (else FRAP level and Bcl2, which were decreased) in MC group than normal group (P  less then  0.05). In comparison with the MC group, total values in MEPD and MEPD + MC groups were decreased (P  less then  0.05) (except FRAP level and Bcl2, which were increased). According to the obtained data, the administration of MEPD extract has potent antioxidant property that attenuates the destructive hepatic effects of MC by initiation of cellular antioxidant pathways and restoration of pathological changes into the physiological form.Stress is an inevitable element of everyday living. Developmental studies suggested that adolescents are more vulnerable and sensitive to the effect of stress due to their developing brains, especially in areas related to stress perception and processing. This voxel-based morphometry study examined the association between various neurobiological markers and the level of perceived stress experienced by adolescents (n = 26) and middle-aged adults (n = 26). Our findings indicated that differences existed in the relationships between perceived stress and the structural volume of the orbitofrontal cortex (OFC) extending to the insula and amygdala. Specifically, the levels of perceived stress and the grey matter volume of the orbitofrontal cortex, the insula, and the amygdala were positively related in adolescents but negatively related for adults. Furthermore, a significant negative correlation between perceived stress and cortisol levels was observed in adults, whereas the relationship between perceived stress and cortisol levels was not significant for adolescents. Perceived stress measurement may be better than cortisol levels in terms of reflecting the emotional states of adolescents. In sum, the relationships between perceived stress and neurobiological markers were different between adolescents and middle-aged adults and thus appeared to be age dependent.Cognitive reserve (CR) delays cognitive decline due to neurodegeneration. Heterogeneous evidence suggests that education may act as CR in Dementia with Lewy Bodies (DLB). No data, however, are currently available on the role of occupation as proxy of CR in this neuropathology. Thirty-three patients with probable DLB were retrospectively included. We performed regression analyses models (TFCE p less then  0.05) and seed-based interregional correlation analyses (p = 0.001, FWE-corrected at cluster-level) with brain metabolism. link3 We aimed at exploring the relationship between brain metabolic connectivity, as assessed by FDG-PET, in the relevant resting-state networks and CR proxies (education, 6-levels occupation, and the specific O*Net occupational profiles). Education modulates executive (ECN), attentive (ATTN) and posterior default mode (PDMN) networks in the highly educated DLB subjects, as shown by an increased metabolic connectivity, acting as a compensatory mechanism. High scores of the 6-levels occupation scale were associated with a decreased connectivity in the anterior default mode (ADMN) and high visual network (HVN), suggesting brain reserve mechanisms. As for the specific O*Net occupational profiles, these modulated ADMN, PDMN, ATTN, ECN, HVN and primary visual network (PVN) connectivity according to different neuroprotection mechanisms, namely neural reserve and compensation against neurodegeneration. This study highlights the relevance of life-long occupational activities at individual level in the neural expression of compensatory and neuroprotective mechanisms in DLB.Neuroimaging studies have demonstrated that autism spectrum disorder (ASD) is accompanied by abnormal functional and structural features in specific brain regions of the default mode network (DMN). However, little is known about the alterations of the topological organization and the functional connectivity (FC) of the DMN in ASD patients. Thirty-seven ASD patients and 38 healthy control (HC) participants underwent a resting-state functional magnetic resonance imaging scan. Twenty DMN subregions were specifically selected to construct the DMN architecture. We applied graph theory approaches to the topological configuration and compare the FC patterns of the DMN. We then examined the relationships between the neuroimaging measures of the DMN and clinical characteristics in patients with ASD. The current study revealed that both the ASD and HC participants showed a small-world regimen in the DMN; however there were no significant differences in global network measures. Compared with the HC group, the ASD group including decreased and increased FC within the DMN.A new method, called granger causality density (GCD), could reflect the directed information flow of the epileptiform activity, which is much closely match with excitatory and inhibitory imbalance theory of epilepsy. Here, we investigated if GCD could effectively localize the Rolandic focus in 50 patients with benign childhood epilepsy with central-temporal spikes (BECTS) from 27 normal children. The BECTS were classified into ictal epileptiform discharges (IEDs; 12 females, 15 males;age, 8.15 ± 1.68 years) and non-IEDs (10 females, 13 males; age, 9.09 ± 1.98 years) subgroups depending on the presence of central-temporal spikes. Multiple correlation-modality analyses (Pearson, across-voxel and across-subject correlations) were used to calculate the couplings between the GCD maps and IEDs-related brain activation map. The individual lateralization coefficient of localize IEDs and multiple regression analysis were used to identify the reliability of the GCD method in localizing the Rolandic focus. In this study, multiple correlation-modality analyses showed that the IEDs-related brain activation map and the GCD maps had highly temporal (coefficient ׀r\= 0.56 ~ 0.65) and spatial (\r\=0.53~0.91) (r\=~ couplings. The proposed GCD method and multiple regression analyses showed consistent findings with the clinical EEG recordings in lateralization of Rolandic focus. Furthermore, the GCD method could reflect the epilepsy-related brain activity during non-IEDs substate. Therefore, the proposed GCD method has the potential to be served as an effective and reliable neuroimaging biomarker to localize the Rolandic focus of BECTS. These findings are critical for clinical early diagnosis, and may promote the progression of treatment and management of pediatric epilepsy.

Laparoscopic Adjustable Gastric Banding (LAGB) has been widely performed in the past at our university bariatric center. Aim of this study was to retrospectively assess long term outcomes of LAGB at our university hospital, with special regard to non-response (EWL < 25%) and rate of band removal.

Retrospective search of prospectively maintained database of our university bariatric center was carried out to find all consecutive patients that had undergone LAGB at our department with a minimum follow-up of 10years. Collected data were sex, age, body mass index (BMI), obesity related diseases remission, complications and weight loss.

After 10years, patients with the band (n = 144) in place had a BMI of 35.2 ± 7.5kg/m2, while %EWL and % TWL were 40.8 ± 52.4 and 18.9 ± 20.7. Seventy-four (41.6%) achieved a success (%EWL > 50), while 38 (21.3%) were non-responders (%EWL < 25), 32 (18%) had an insufficient weight loss (25 < %EWL < 50) and 34 (19.1%) underwent band removal. Among these, 6 (3.4%) were removed for complications and 28 (15.7%) for insufficient weight loss. Weight regain occurred in 38 out of 144 (26.4%) subjects with the band in place at 10years. Only one case of early vomiting with readmission for medical treatment was recorded. Slippage, erosion/migration and port/tube complications occurred in 4 (2.2%), 2(1.1%) and 9(5%) cases respectively.

LAGB is a safe and moderately effective bariatric procedure but it showed disappointing rates of removal, non-response and remission from comorbidities. However, LAGB could still be proposed for selected/motivated patients.
