ABSTRACT

Objective:To evaluate the role of hippocampal REV-ERBα in postoperative cognitive dysfunction in rats.Methods:Thirty-two SPF healthy male Sprague-Dawley rats, aged 12-14 weeks, weighing 360-380 g, were divided into 4 groups ( n=8 each) using a random number table method: control group (group C), surgery group (group S), surgery + dimethyl sulfoxide (DMSO) group (group SD), and surgery + SR9009 group (group SS). Exploratory laparotomy was performed under sevoflurane anesthesia in S, SD and SS groups.Normal saline containing 0.1% DMSO was injected into hippocampal CA1 area at 1 h before laparotomy, with 2 μl on each side in group SD, and REV-ERBα agonist SR9009 (in normal saline containing 0.1% DMSO) was injected into hippocampal CA1 area at 1 h before laparotomy, with 2 μl on each side in group S+ SR9009.Morris water maze test was performed at 1 and 3 days after operation.Rats were sacrificed at 1 h after the end of Morris water maze test on day 3 after surgery, and the hippocampal tissues were obtained for determination of the expression of REV-ERBα, Brain and Muscle ARNT-Like 1 (BMAL1) protein, synaptophysin (SYN), postsynaptic density (PSD)-95 protein and N-methyl-D-aspartate receptor 2B subunit (GRIN2B) (by Western blot) and microscopic examination of the morphology of hippocampal neurons and Nissl bodies (by Nissl staining), and the viable neurons were counted. Results:Compared with group C, the percentage of time of staying at the target quadrant was significantly decreased, and the number of crossing platform was reduced on days 1 and 3 after exploratory laparotomy, the expression of REV-ERBα, BMAL1, PSD95, SYN and GRIN2B was down-regulated, and the number of viable neurons was decreased in group S and group SD ( P<0.05). Compared with group S and group SD, the percentage of time of staying at the target quadrant and the number of crossing platform were significantly increased on days 1 and 3 after exploratory laparotomy, the expression of REV-ERBα and PSD95 was up-regulated, the number of viable neurons was increased ( P<0.05), and no significant change was found in the expression of BMAL1, SYN and GRIN2B in group SS ( P>0.05). There was no significant difference in the indexes mentioned above between group S and group SD ( P>0.05). Conclusions:Activation of REV-ERBα can improve postoperative cognitive dysfunction, and the mechanism may be related to up-regulation of PSD95 expression in hippocampus and reduction of neuronal damage in rats.

ABSTRACT

Objective:To evaluate the relationship between nuclear receptor subfamily 1, group D, member 1 (Rev-erbα) and NOD-like receptor protein 3 (NLRP3) inflammasome during myocardial ischemia-reperfusion (I/R) in diabetic rats.Methods:SPF-grade healthy male Sprague-Dawley rats, weighing 210-240 g, in which 1% streptozotocin 60 mg/kg was intraperitoneally injected to develop the model of type 1 diabetes mellitus.Eighteen non-diabetic rats were divided into 2 groups by the random number table method: non-diabetic sham operation group (NS group, n=6) and non-diabetic myocardial I/R group (NIR group, n=12). Thirty diabetic rats were divided into 3 groups by the random number table method: diabetic sham operation group (DS group, n=6), diabetic myocardial I/R group (DIR group, n=12), and diabetic myocardial I/R + Rev-erbα inhibitor SR8278 group (DIR+ SR group, n=12). Myocardial I/R model was developed by ligation of left anterior descending coronary artery for 30 min followed by reperfusion for 120 min.In DIR+ SR group, SR8278 2 mg/kg was injected via the femoral vein at 1 h before ischemia.At the end of reperfusion, blood samples from the right carotid artery were collected for determination of serum creatine kinase-MB (CK-MB), lactate dehydrogenase (LDH) and cardiac troponin I (cTnI) levels (by enzyme-linked immunosorbent assay). Then the rats were sacrificed, hearts were removed and myocardial tissues were obtained for determination of the percentage of myocardial infarct size (by TTC method) and expression of Rev-erbα, NLRP3 and IL-1β (by Western blot) and for microscopic examination of pathologic changes (by HE staining). Results:Compared with sham-operated rats, the serum concentrations of CK-MB, LDH and cTnI were significantly increased, the expression of Rev-erbα, NLRP3 and IL-1β in myocardial tissues was up-regulated ( P<0.05), and the pathological injury of myocardial tissues was obvious in myocardial I/R rats.Compared with NIR group, the percentage of myocardial infarct size and levels of serum CK-MB, LDH and cTnI were significantly increased, the expression of Rev-erb α, NLRP3 and IL-1β was up-regulated ( P<0.05), and the pathological injury of myocardial tissues was aggravated in DIR group.Compared with DIR group, the percentage of myocardial infarct size and serum CK-MB, LDH and cTnI levels were significantly decreased, the expression of Rev-erbα, NLRP3 and IL-1β was down-regulated ( P<0.05), and the pathological injury of myocardial tissues was reduced in DIR+ SR group. Conclusions:Rev-erbα can promote activation of NLRP3 inflammasome and is involved in the pathophysiological mechanism of myocardial I/R injury in diabetic rats.

ABSTRACT

Background: Maharashtrian population is at the risk of cervical cancer (CC) and is not subjected to investigate the cancer susceptibility in association with genetic determinants. Objectives: This study was aimed to evaluate the association of single nucleotide polymorphisms (SNPs) in DNA repair gene xeroderma pigmentosum complementation group D (XPD) with CC risk from rural Maharashtra. Materials and Methods: We used polymerase chain reaction and-restriction fragment length polymorphism to analyze SNPs in XPD gene from 350 patients with CC and 400 age and sex-matched disease-free controls. Results: The results indicated no significant difference in the genotype distribution between CC patients and controls for the XPD gene at codon 156 of exon 6 and codon 751 of exon 23, but the results showed that allele frequencies of XPD Asn 312 of codon 312 of exon 10 (odds ratio = 0.31; 95% confidence intervals = [0.16–0.63]; P = <0.001) genotype showed negative association with CC risk. Conclusion: This study indicated the role of XPD (cd312) in modifying genetic susceptibility of an individual to CC in Maharashtrian patients.

ABSTRACT

Abstract This study aimed to determine the association between the polymorphisms and haplotypes in the xeroderma pigmentosum group D (XPD) gene and the risk of pancreatic cancer in the Chinese Han population. SNaPshot was used for genotyping six SNP sites of the XPD gene. Comparisons of the correlations between different genotypes in combination with smoking and the susceptibility to pancreatic cancer were performed. Individual pancreatic cancer risk in patients who carry mutant C alleles (AC, CC, and AC+CC) at rs13181 increased (p < 0.05). Taking non-smoking individuals who carry the AA genotype as a reference, and non-smoking individuals who carry mutant allele C (AC+CC), the risk of pancreatic cancer increased by 3.343 times in individuals who smoked ≥ 20 cigarettes daily, 3.309 times in individuals who smoked ≥ 14 packs per year, 5.011 times in individuals who smoked ≥ 24 packs per year, and 4.013 times in the individuals who smoked ≥ 37 packs per year (P < 0.05). In addition, haplotype analysis revealed that haplotype AGG, which comprised rs13181, rs3916874 and rs238415, was associated with a 1.401-fold increase in pancreatic cancer risk (p < 0.05). We conclude that the polymorphism of XPD Lys751Gln (rs13181) in combination with smoking contributes to increased risk of pancreatic cancer in the Chinese Han population. Haplotype AGG might be a susceptibility haplotype for pancreatic cancer.

ABSTRACT

Rotaviruses are etiological agents of diarrhea both in humans and in several animal species. Data on avian Group D rotaviruses (RVD) are scarce, especially in Brazil. We detected RVD in 4 pools of intestinal contents of broilers, layer and broiler breeders out of a total of 111 pools from 8 Brazilian states, representing an occurrence of 3.6%, by a specific RVD RT-PCR targeting the VP6 gene. Phylogenetic tree confirmed that the Brazilian strains belong to group D and 3 of the sequences were identical in terms of amino acid whereas one showed 99.5% identity with the others. The sequences described in this study are similar to other sequences previously detected in Brazil, confirming the conserved nature of the VP6 protein.


Rotavírus são agentes etiológicos de diarreia tanto em humanos como em várias espécies animais. Dados sobre rotavírus do grupo D (RVD) em aves são escassos, especialmente no Brasil. Nós detectamos RVD em 4 pools de conteúdo intestinal de frango de corte, poedeiras e matrizes de um total de 111 pools originários de 8 estados brasileiros, representando uma ocorrência de 3,6% a partir de uma RT-PCR específica para RVD, tendo como alvo o gene VP6. A árvore filogenética confirmou que as amostras brasileiras pertencem ao grupo D e três das sequências obtidas foram idênticas em termos de aminoácidos enquanto uma apresentou 99,5% de identidade com as demais. As sequências aqui definidas são semelhantes a outras sequências previamente definidas no Brasil, confirmando a natureza conservada da proteína VP6.

ABSTRACT

Las infecciones originadas por bacterias del género Salmonella son una de las principalescausas de pérdidas económicas en la industria avícola, se caracterizan generalmentepor la presentación de cuadros diarreicos y septicémicos que llevan a las aves a unamarcada disminución en la producción y a la muerte. En Colombia, debido al efectonegativo que produce Salmonella spp. en las aves, y con el objetivo de poder controlarla enfermedad, se utiliza una gran variedad de productos antimicrobianos, de los cuales no se posee suficiente información acerca de su comportamiento en cuanto asensibilidad y resistencia frente a las cepas de Salmonella spp. de campo. El objetivo de este estudio fue determinar la respuesta de 20 cepas de Salmonellas grupo D (móviles einmóviles) aisladas de aves ponedoras comerciales en Colombia frente a diferentes antimicrobianos. Para su aislamiento y tipificación se utilizaron técnicas microbiológicas convencionales, pruebas bioquímicas, serológicas y pruebas de susceptibilidad a los antibióticos por difusión en agar. Los resultados revelaron una resistencia total hacia la estreptomicina, seguida de altas resistencias para tetraciclina y florfenicol, y una menor resistencia a productos como fosfomicina y cloramfenicol.


Infections caused by Salmonella bacteria are a major cause of economic losses in thepoultry industry, because caused mainly by the presentation of diarrheas and septicemic birds leading to a marked decrease in the production death. In Colombia due to the negative effect by Salmonella spp. in poultry, and with the aim of controlling the disease, the people have been using a variety of antimicrobials, which do not possess sufficient information about its behavior in terms of sensitivity and resistance againststrains of Salmonella spp. field. The aim of this study was to determine the response of20 strains of Salmonella group D (mobile and non mobile) isolated from commercial laying hens in Colombia against different antimicrobials. For the isolation and characterization are using conventional microbiological techniques, biochemical tests, serological testing and antibiotic susceptibility by agar diffusion. The results revealed a total resistance to streptomycin, followed by tetracycline and Florfenicol and less resistance to products such as Fosfomycin and chloramphenicol.

ABSTRACT

Objective To explore the association between XPD codon 751 polymorphism and esophageal cancer (EC) by systematically reviewing the risk of the original studies. Methods A comprehensive search was conducted to identify all case-control studies of XPD codon 751 polymorphism and EC risk. Meta-analysis was applied with Rev Man 4.2 software for calculation of pooled OR value (with 95%C1)of EC, esophageal squamous cell carcinoma (ESCC)and esophageal adenocarcinoma (EAC). Results Of the 12 case-control studies selected for this Meta-analysis, a total of 2558 EC cases and 5122 controls were included. Compared with the wild-type homozygote Lys/Lys, the pooled Odds Ratios (with 95% CI) of Lys/Gln, Gin/Gin, (Lys/Gln + Gln/Gln) genotypes of XPD codon 751 polymorphism for EC risk were 1.19(1.05, 1.34), 1.22(0.86, 1.74), 1.20(1.01,1.42), respectively. In a stratified analysis, a total of 1417 ESCC cases and 2312 controls were included, and individuals carrying Lys/Gln genotype or (Lys/Gln+Gln/Gln) had 1.22-fold or 1.24-fold excess risks for ESCC compared with those carrying Lys/Lys genotype. A total of 935 EAC cases and 2604 controls were included, and none of the genotype of XPD codon 751 genetic polymorphism was found to be related to EAC. Conclusion Both heterogyzote Lys/Gln and (Lys/Gln + Gln/Gln) for XPD codon 751 genetic polymorphism were associated with an increased risk of developing esophageal cancer. Furthermore, heterogyzote Lys/Gln and (Lys/Gln + Gln/Gln) for XPD codon 751 genetic polymorphism might have increased the risk of ESCC, but have no association with EAC.

ABSTRACT

Acute gastroenteritis due to Salmonella species, which usually improves on conservative treatment, can progress to sepsis and extraintestinal focal infection in very young infants. Frequent sites for extraintestinal infections are meninges, bone, joints, spleen and intravascular sites but scrotal abscess due to salmonella in children has been very rare. Literature search revealed only one newborn case of scrotal abscess with bacteremia due to salmonella group D which developed after circumcision. We, herein, report a 42 day old infant who initally presented with diarrhea that progressed to sepsis and scrotal abscess. Despite the use of susceptible antibiotics, the patient improved only after surgical drainage.
