Published: September 2019

This study is designed to detect the level of cytokine IFN-γ concentration, and some antioxidants, including super oxide dismutase (SOD) and Vitamin C, and to estimate the level of sex hormones (FSH and LH), and to determine auto-antibodies (antiphospholipid antibodies (APA) IgG\IgM, and anticardiolipin antibodies (ACA) IgG\IgM) and to estimate the blood parameters in 51 miscarriage women infected with T.gondii distributed depending on the type of antibodies. Additionally, 39 volunteers non-infected with T.gondii included (19 miscarriage women, 10 pregnant women and 10 non-pregnant women). ELISA and spectrophotometer method were used in this study. The results of IFN-γ showed a significant increase)p<0.05) in the level of IFN-γ in women infected with T.gondii compared with volunteer groups. The current study shows a significant difference in the level of hormones, where the concentration of LH hormone increased in married non-pregnant women compared with other groups, while the concentration of FSH hormone increased in toxoplasmosis women compared with volunteer groups. The results of antioxidants showed no significant difference in Vitamin C activity in infected women compared with volunteer groups, while super oxide dismutase (SOD) activity was significantly lower in infected women compared with volunteer groups. The results of autoantibodies showed a significant difference in anticardiolipin antibodies (ACA) IgM level, the highest level was in aborted women infected with acute infection (IgM Ab), while the anticardiolipin antibodies (ACA) IgG level recorded the highest level in aborted women infected with both acute and chronic infection (IgG&IgM)). The results showed no significant difference in antiphospholipid antibodies (APA) IgM level in infected women when compared to the volunteer groups, while the results showed significant difference in antiphospholipid antibodies (APA) IgG level, where the highest concentration was in the volunteer groups (pregnant and non-pregnant married women). The results of blood parameters showed significant differences in differential leucocytes except for Basophils and Monocytes, and the results showed significant differences in differential erythrocytes, HB, PLT, and PCV.

Authors: Et al. Hussein 
Published: September 2019

Ethanolic crude extracts of leaves from Laurus nobilis and Alhagi maurorumfor were screened for alkaloids, saponins, tannins, anthraquinones, steroids, flavonoids, glycosides, and glucosides contents. Biochemical activities, including antibacterial activity, antioxidant, and antihemolytic activity, were investigated. Antibacterial activity against Three types of pathogenic bacteria was detected by disc diffusion analysis and characterized by zone of inhibition (ZOI). Antioxidant properties were determined by a diphenyl-1- picrylhydrazyl (DPPH) method. Results revealed that the inhibitory activity of the plants against G+ve and G-ve bacteria were different, where the greatest ZOI of Alhagi maurorum against Staphylococcus aureus was 12.66 mm, while its effect against Pseudomonas aeruginosa generated an 8.33 mm ZOI, with no did not effects on Escherichia coli. Extract of Laurus nobilis against Escherichia coli with a ZOI reached to 10.33 mm, but did not significantly influence the growth of Staphylococcus aureus and Pseudomonas aeruginosa. When the plant extracts were mixed in equal quantities, the percentage of the effect were increased, where the greatest effect of the mixed observed in E. coli was a 16.66mm ZOI, and in Staphylococcus aureus to 15.66mm. In Pseudomonas aeruginosa the ZOI reached to a 12.33 mm. This is referred to as synergistic effect between these plants against pathogenic bacteria. The extracts did not have any toxic effects on human red blood cells.

Authors: Et al. Alkhafajy 
Published: September 2019

Cholesteryl ester transfer protein gene contains some single nucleotide polymorphisms, which have been associated with serum high-density lipoprotein concentration and other lipoproteins. This study is done for determining of cholesteryl ester transfer protein polymorphism and evaluate its effect on serum lipid profile concentrations in some hyperlipidemic patients compared with healthy subjects in Salah Al-din governorate-Iraq. Blood samples were taken from (90) patients suffering from hyperlipidemia, and (70) samples that were apparently healthy controls. Serum lipid concentrations were measured by enzymatic assays. The polymorphism was genotyped using polymerase chain reaction restriction fragment length polymorphism analysis. The results showed that there was a significant decrease (P<0.05) in the frequency B2 allele, and B1B2, B2B2 genotype, and a significant increase (P<0.05) in the frequency B1 allele, and B1B1 genotype between patients and controls groups. There was a non-significant decrease in the levels of high density lipoproteins, total cholesterol, low density lipoproteins, and very low density lipoproteins levels, and non-significant increase in levels of triglycerides in individuals with the B1B1 genotype than in the B1B2 and B2B2 genotype. However, high density lipoproteins showed a significant decrease (P<0.001) between individuals with the B1B1 genotype and B2B2 genotype. Also, there was a non-significant difference in the levels of high density lipoproteins, total cholesterol, low density lipoproteins, and very low density lipoproteins levels, in individuals with the B1B2 genotype when compared with that of the B2B2 genotype.

Abstract
Background: Pregnancy induced hypertension is the development of new hypertension with or without proteinuria after 20 weeks of pregnancy. The prevalence of pregnancy induced hypertension in Ethiopia ranges from 2.2 to 18.3%. However, little is known about the adverse perinatal outcomes of pregnancy induced hypertension in Tigray Regional State, Ethiopia.Therefore the objective of this study was to assess effect of pregnancy induced hypertension on adverse perinatal outcomes in Tigray Regional State, Ethiopia. Methods: a prospective cohort study was conducted on a total sample of 782 pregnant women attending antenatal care in hospitals of Tigray regional state, Ethiopia. Data were collected using interviewer-administered questionnaire and review of their medical records from February 1, 2018, to February 30, 2019. Data analysis was performed using Stata version 14.0. Relative risk with 95% CI for the association between pregnancy induced hypertension and perinatal outcomes were assessed using Poisson regression analysis. Results: In this study the overall incidence of adverse perinatal outcome was higher among women with pregnancy induced hypertension than normotensive women ( 66.4% vs 22.2%). After adjusted for confounders women with pregnancy induced hypertension were born babies with a higher risk of low birth weight (adjusted RR(95%CI)= 5.1(3.4,7.8)), birth asphyxia (aRR=2.6(1.9,3.8)), small for gestational age (aRR=3.3(2.3,4.6)), preterm delivery (aRR=5.2(3.4,7.9)), admission to neonatal intensive care unit (aRR=5.1(3.1,8.4)) and with a higher risk of perinatal death (aRR=3.6(1.8,7.4)) compared to normotensive pregnant women Conclusions: Higher incidences of adverse perinatal outcomes were occurred among women pregnancy induced hypertension in Tigray regional state, Ethiopia. Hence health care providers should strengthen prevention, early diagnosis and prompt management of pregnancy induced hypertension to reduce adverse perinatal outcomes of pregnancy induced hypertension.

Published: September 2019

Abstract
Sclerotinia stem rot (SSR), caused by Sclerotinia sclerotiorum (Lib.) de Bary, is an important cause of yield loss in soybean. Although many papers have reported different loci contributing to partial resistance, few of these were proved to reproduce the same phenotypic impact in different populations. In this study, we identified a major quantitative trait loci (QTL) associated with resistance to SSR progression on the main stem by using a genome-wide association mapping (GWAM). A population of 127 soybean accessions was genotyped with 1.5M SNPs derived from genotyping-by-sequencing (GBS) and whole-genome sequencing (WGS) ensuring an extensive genome coverage and phenotyped for SSR resistance. SNP-trait association led to discovery of a new QTL on chromosome 1 (Gm01) where resistant lines had shorter lesions on the stem by 29 mm. The impact of this QTL was even more significant in the descendants of a cross between two lines carrying contrasted alleles for Gm01. Individuals carrying the resistance allele developed lesions almost 50% shorter than those bearing the sensitivity allele. These results suggest that this region harbors a promising resistance QTL to SSR that can be used in soybean breeding program.
Shock wave-enhanced emission photoacoustic streaming versus photon-induced photoacoustic streaming modes for clearing root canal bacteria using erbium-doped yttrium aluminum garnet lasers: An in vitro study
Authors: Wang Xiao-Na , Shi Jing 
Published: September 2019

Abstract
Background : The root canal cleaning efficiency of the photon-induced photoacoustic streaming (PIPS) mode in erbium-doped yttrium aluminum garnet (Er:YAG) lasers is controversial. Shock wave-enhanced emission photoacoustic streaming (SWEEPS), a novel mode in Er:YAG lasers, creates a strong shock wave in a narrow container. We accordingly hypothesized that it may effectively eliminate bacteria from narrow root canals. The present study aimed to compare the bacterial clearance efficiency between the SWEEPS and PIPS modes for Er:YAG lasers designed for root canal treatment. Methods: The distal and palatal roots of 130 freshly extracted human molars were used. The smear layer was first removed by conventional root canal preparation. All samples were then sterilized in an autoclave. The samples were subsequently exposed to Enterococcus faecalis and incubated for 4 weeks to establish E. faecalis infection models. The models were divided into three groups according to the irrigation method (n = 40 per group): 3% sodium hypochlorite (NaOCl) activated using the SWEEPS Er:YAG laser mode, 3% NaOCl activated using the PIPS Er:YAG laser mode, and 3% NaOCl without activation. Results: The bacterial clearance efficiency, based on the colony-forming unit count, was significantly higher in the SWEEPS group than in the PIPS and NaOCl groups. Moreover, scanning electron microscopy after irrigation revealed that the SWEEPS group had the least number of bacteria. Conclusions: The SWEEPS mode may be more effective than the PIPS mode for eradicating E. faecalis from root canals.

Abstract
Background: Eribulin improves survival in pre-treated HER2-negative advanced breast cancer (ABC). However, limited data exist on co-morbidities and central nervous system (CNS) efficacy. The purpose of this study was to review eribulin’s efficacy and safety in everyday clinical practice with special focus on age, body mass index (BMI) and central nervous system (CNS) activity.Methods: An observational study was conducted in a series of HER2-negative ABC patients treated from January’14-December’17 outside a clinical trial. Objective Response Rate (ORR), Progression Free Survival (PFS), Overall Survival (OS), and association of clinical and pathological variables with outcome were evaluated. Results: Ninety-five women were treated with at least one cycle of eribulin. Median age was 57 (33-83), and 18% were obese. Median number of prior chemotherapies for ABC was 3 (2-5) and 76% of patients had visceral metastases, including 21% with CNS involvement. Most tumors were estrogen receptor-positive (79%). ORR and stable disease (SD) at 6 months were 26.2% and 37.5%, respectively. Remarkably, relevant CNS efficacy was observed with eribulin: 20% of patients obtained partial response and 25% SD. Treatment was generally well tolerated and manageable, with 29% grade 3 and 10.9% grade 4 toxicities. Median PFS and OS were 4.1 months (CI95% 3.2-4.9) and 11.1 months (CI95% 9.5-14.7), respectively. Triple-negative disease, >2organs involved and being younger than 70 years old were independent prognosis factors for worse OS in multivariate analysis. Most patients (75%) progressed in pre-existing metastases sites.Conclusions: In everyday clinical practice, eribulin’s efficacy seems similar to pivotal trials. CNS-efficacy was observed. TNBC, >2 organs involved and being younger than 70 years old were independent prognosis factors for worse OS. Remarkably, less incidence of grade 4-toxicity compared to previous studies was found.

Abstract
Background: Health information systems bring several benefits for the health system, healthcare providers, and the population. As a set of tools for the collection, storage, management and transmission of health data, their role to support the modernization of health systems, improve access to quality health care and reduce costs in developing countries is unquestionable. However, HIS implementation in low-income countries face several challenges. In Gabon, a unique initiative called eGabon has been launched in order to modernize the country’s infrastructures, notably through the deployment of a unique national electronic HIS that will connect health care institutions and providers at all levels in the whole country. Objective: This study aims to identify the factors influencing the optimal use of the national electronic HIS by healthcare providers in Gabon. Methods: We used an adaptation of the Information System Success Model ( and developed a questionnaire that was distributed to 2600 healthcare providers across the country). Reliability and validity of the instrument were tested, and we performed a logistic regression to identify the factors influencing healthcare providers’ perceptions towards the national electronic HIS. Results: A total of 2327 questionnaires were received from healthcare providers, of which 1930 were usable in the analyses. The reliability and validity of the questionnaire were supported. The logistic regression identified five constructs that significantly influence perceived system impact: System quality, Information quality, Support quality, Actual use and Useful functions. The model explains 30% of the variance in providers’ perception that the HIS leads to positive impacts. Discussion: This study provides support to the use of an adapted ISSM in the context of HIS implementation in a low-income setting. The results show that health care providers’ perceptions regarding the positive impact of the HIS are influenced by their previous use of a HIS, the extent of their use, their perceptions of system quality, information quality and quality of the support provided to users. These results could inform the development of strategies to ensure adequate change management and user experience for the implementation of the national electronic HIS, and eventually in other low-resources settings.

Authors: Hu Jun , Wang Fang , Liu Logen , Wenfeng Ning 
Published: September 2019

Abstract
BACKGROUND: Mounting evidence has shown that long noncoding RNAs (lncRNAs) can function as competing endogenous RNAs (ceRNAs) which participate in the initiation and progression of cancers. In the ceRNA network, lncRNAs, microRNAs (miRNAs) and mRNAs, communicate with and co-regulate each other. Rarely there is a systematic lncRNA-mediated ceRNA network and potential specific ceRNA pairs or triples of esophageal cancer (EC). In this study, we investigate the lncRNA-mediated ceRNA network in EC and screen the potential prognostic lncRNA biomarkers. METHODS: We obtained mRNA, miRNA, and lncRNA expression data and relevant clinical features on patients with EC from The Cancer Genome Atlas (TCGA), and used the edgR package to identify differentially expressed mRNAs, lncRNAs and miRNAs between EC samples and normal samples. The EC ceRNA network was constructed based on miRNA target prediction through the databases of miRcode, miRDB, miRTarBase and TargetScan. And then Pearson’s correlation analysis was adopted to identify co-expression mRNA-lncRNA pairs. Finally, the robust likelihood-based survival analysis and Cox regression models were used to identify prognosis-related lncRNAs, which was evaluated by Kaplan-Meier and receiver operating characteristic (ROC) curve analysis. RESULTS: A total of 3,200 mRNAs, 131 miRNAs and 1,338 lncRNAs were identified as significantly differentially expressed in EC, of which, 30 mRNAs, 15 lncRNAs, and 8 miRNAs were incorporated in the ceRNA network. According to the ceRNA network node degrees, lncRNA MAGI2-AS3, hsa-mir-93 and TGFBR2 were the key genes. Also, the ceRNA network revealed some important ceRNA pairs and triples, such as SNX29P2-TGFBR2 and MAGI2-AS-hsa-mir-143-COL1A1. Finally, we developed a six-lncRNA signature (ZNF341-AS1, AC130324.2, AC027271.1, AL591212.1, AL732314.4 and LOC105372352), with improved diagnostic potential for EC with the area under the ROC curve of 0.93. CONCLUSIONS: our present work sheds new light on the tumorigenesis roles of lncRNA-mediated ceRNA network in EC and identifies a six‐lncRNA model that could be used as candidate prognostic signature.

Abstract
Background: At the aim of this study, we investigated the effects of different kind of cytokines and the combinations of which on human carbonic anhydrase IX ( hCAIX) expression in HT-29 cell selected as colon carcinoma model for different doses and time of exposure to determine role of cytokines for treatment of colon carcinoma cells. Results: To sum up, h CA9 expression in the levels of gene and protein increased in HT-29 cells when stimulated with 1000 U/mL TGF-β for 24 h. The stimulation of HT-29 cells with IL1 α alone and IL1α- TGF-β combination has not revealed any effect on hCA9 expression in both levels of gene and protein in contrast to, 1000 U/mL IL1α-TNFα and especially TGFβ-TNFα have reducing effect on h CA9 expression level in HT-29 cells for time ranges of 24 h, 48 h, 72 h. In addition to this data, it was observed that HT-29 cells at the phase of G0G1 are arrested in cell cycle when stimulated with either of 1000 U/mL IL1α-TNFα and TGFβ-TNFα. Moreover, it was observed that h CA9 expression level in HT-29 cells decreases at the phases of synthesis (S) and G2M. Discussion: We concluded that combination of TNFα-TGFβ has created antagonistic effect on hCA9 expression in HT-29 colon cancer cell model. On the other hand, combination of TNFα-IL1α caused sinergistic effect on h CA9 expression level in this cell model. When these results are demonstrated decrease in the cytokine exposed hCA9 expression is a finding to develop a novel approach for anticancer therapy. Conclusion: Our finding related to the change in the expression of hCA9 following cytokine stimulate to colon cancer cell line gives an idea about the effect of cytokine stimulation on the expression of this gene which will be a hot spot research in colon carcinogenesis. Methods: HT-29 colon cells were chosen as a colorectal adenocarcinoma model. hCA9 gene expression in the level of mRNA was measured in cytokines stimulated HT-29 cells by Quantitative Real-time PCR. Meanwhile, hCAIX expression in the level of protein and cell cycle aassay were detected by flow cytometry.
