    This study evaluated the CRISP2 gene's functional single nucleotide polymorphisms, and its results may be advantageous for future population-based studies and early diagnostic discoveries, particularly in developing effective treatments. The CRISP2 gene encodes a secretory protein with a high cysteine content, which belongs to the family of cysteine-rich secretory proteins (CRISP). SNPs are genetic variations that may affect a protein's structure or functionality. Prior to carrying out a broader population investigation, it is possible to evaluate suspected functional SNPs since it is challenging to uncover functional SNPs in disease-linked genes. As a result, using various bioinformatic prediction models, the potentially harmful three SNPs of the CRISP2 gene were predicted in this in-silico study from the neutral ones. Out of a pool of 260 nsSNPs, three SNPs (L56V, M176I, and C196R) been selected to anticipate their impacts on functions and structures along with their capability to impair protein stability. Actually, two of the three SNPs in the CRISP2 gene L56V and C196R were identified as possibly detrimental, although M176I was not. But all of these SNPs dropped significantly protein stability, per the I-Mutant suite

    The objective of this study was to evaluate the association and effect of CRISP2 variants on the risk of asthenozoospermia, a male infertility condition marked by absent or diminished sperm motility. There are numerous reasons why individuals develop asthenozoospermia. Therefore, it is crucial to understand the molecular mechanisms underlying this condition of infertility. Furthermore, seminal plasma, a rich source of sperm quality-related biomarkers, transports the many spermatozoa pools that make up human ejaculate down the epididymis. These spermatozoa vary in size, shape, and motility. The morphology and mobility of male ejaculated spermatozoa are affected by a number of genes, including CRISP2. In seminal samples from 120 Iraqi infertile male patients and 40 healthy males who were matched for age, gender, and ethnicity as a control group, the connection of the CRISP2 gene single nucleotide polymorphisms L56V, M176I, and C196R with infertility was investigated. According to statistical analysis of the genotype distribution of these three nsSNPs of the CRISP2 gene in patients with the asthenozoospermia subgroup and the control group, there weren't detectable differences in genotype distribution between AS, OAS, OTA, and fertile men in the Iraqi research sample. Based on allele frequencies, C, T, and G were determined to be protective alleles, with OR values of 0.74, 0.64, and 2.0, respectively

    This study was aimed to assess expression of IL-22 gene in patients with newly diagnosed autoantibodies against the thyroid antigens; anti-thyroglobulin (anti-TG), and anti-thyroid peroxidase (anti-TPO) in comparison with patients previously diagnosed and treated for autoimmune hypothyroidism as well as healthy control individuals. Twenty-eight patients with positive anti-TG and/or anti-TPO were enrolled in this study along with twelve age- and gender-matched healthy controls. Reverse transcription-quantitative polymerase chain reaction (RT-qPCR) was used to assess gene expression and fold change among the study groups. Results revealed anti-TG concentration ranges of 134.3 to 2998.9 IU/mL and anti-TPO concentration ranges of 41.6 to 1018.4 IU/mL in patients while control group individuals were negative for these autoantibodies. The mean fold change of IL-22 expression (2-∆∆Ct) was the highest in newly diagnosed patients compared to patients on treatment for autoimmune hypothyroidism and healthy controls indicating the potential role of IL-22 in the early stages of the disease and its contribution in immune imbalance

    Infertility considered as a multifactorial condition; the small nuclear ribonucleoprotein polypeptide N (SNRPN) gene is an imprinted gene. However, abnormal imprinting of this gene due to the methylation may result in abnormal function or silencing of the gene. Main aim of this study is to investigate the methylation present at the promoter of (SNRPN) gene and its role as a risk factor for male infertility. Sixty- three infertile males with age mean (32.28 ± 6.88 years) and 13 fertile males as a control age mean (34.07 ± 6.52 years) were investigated. Whole genomic DNA was extracted, DNA integrity was checked using β-globin gene as an internal control. The targeted region was amplified by polymerase chain reaction (PCR) technique. In addition, the SNRPN gene's promoter methylation was qualitatively detected using Real time polymerase chain reaction (qPCR) utilizing two sets of primers: methylated and un-methylated. Results reveled that all of the 63 infertile males were experiencing decrease in sperm concentration 9.42 ± 8.70 million/ml, reduced progressive motility 2.89 ± 5.45% as well as strange sperm morphology 27.06 ± 16.50%, while the values in the control group are normal. The results of the current investigation showed that the promoter of SNRPN was hypermethylated in some samples 22.7%, somewhat methylated in others 20.4%, and unmethylated in other samples 56.8% from infertile samples, while none of the 13 control samples had any methylation. These findings suggest that SNRPN gene may be associated with the negative changes in semen parameters, which could lead to male infertility

    Child health promotion in underserved communities: The FAMILIA trial

    Get PDF
    Background: Preschool-based interventions offer promise to instill healthy behaviors in children, which can be a strategy to reduce the burden of cardiovascular disease later. However, their efficacy in underserved communities is not well established. Objectives: The purpose of this study was to assess the impact of a preschool-based health promotion educational intervention in an underserved community. Methods: This cluster-randomized controlled study involved 15 Head Start preschools in Harlem, New York. Schools and their children were randomized 3:2 to receive either a 4-month (50 h) educational intervention to instill healthy behaviors in relation to diet, physical activity, body/heart awareness, and emotion management; or their standard curriculum (control). The primary outcome was the change from baseline in the overall knowledge, attitudes, and habits (KAH) score of the children at 5 months. As secondary outcomes, we evaluated the changes in KAH subcomponents and emotion comprehension. Linear mixed-effects models were used to test for intervention effects. Results: The authors enrolled 562 preschool children age 3 to 5 years, 51% female, 54% Hispanic/Latino, and 37% African-American. Compared with the control group, the mean relative change from baseline in the overall KAH score was ∼2.2 fold higher in the intervention group (average absolute difference of 2.86 points; 95% confidence interval: 0.58 to 5.14; p = 0.014). The maximal effect was observed in children who received >75% of the curriculum. Physical activity and body/heart awareness components, and knowledge and attitudes domains, were the main drivers of the effect (p values <0.05). Changes in emotion comprehension trended toward favoring intervened children. Conclusions: This multidimensional school-based educational intervention may be an effective strategy for establishing healthy behaviors among preschoolers from a diverse and socioeconomically disadvantaged community. Early primordial prevention strategies may contribute to reducing the global burden of cardiovascular disease.

    Different Lifestyle Interventions in Adults From Underserved Communities: The FAMILIA Trial

    Get PDF
    BACKGROUND: The current trends of unhealthy lifestyle behaviors in underserved communities are disturbing. Thus, effective health promotion strategies constitute an unmet need. OBJECTIVES: The purpose of this study was to assess the impact of 2 different lifestyle interventions on parents/caregivers of children attending preschools in a socioeconomically disadvantaged community. METHODS: The FAMILIA (Family-Based Approach in a Minority Community Integrating Systems-Biology for Promotion of Health) study is a cluster-randomized trial involving 15 Head Start preschools in Harlem, New York. Schools, and their children's parents/caregivers, were randomized to receive either an "individual-focused" or "peer-to-peer-based" lifestyle intervention program for 12 months or control. The primary outcome was the change from baseline to 12 months in a composite health score related to blood pressure, exercise, weight, alimentation, and tobacco (Fuster-BEWAT Score [FBS]), ranging from 0 to 15 (ideal health = 15). To assess the sustainability of the intervention, this study evaluated the change of FBS at 24 months. Main pre-specified secondary outcomes included changes in FBS subcomponents and the effect of the knowledge of presence of atherosclerosis as assessed by bilateral carotid/femoral vascular ultrasound. Mixed-effects models were used to test for intervention effects. RESULTS: A total of 635 parents/caregivers were enrolled: mean age 38 ± 11 years, 83% women, 57% Hispanic/Latino, 31% African American, and a baseline FBS of 9.3 ± 2.4 points. The mean within-group change in FBS from baseline to 12 months was ∼0.20 points in all groups, with no overall between-group differences. However, high-adherence participants to the intervention exhibited a greater change in FBS than their low-adherence counterparts: 0.30 points (95% confidence interval: 0.03 to 0.57; p = 0.027) versus 0.00 points (95% confidence interval: -0.43 to 0.43; p = 1.0), respectively. Furthermore, the knowledge by the participant of the presence of atherosclerosis significantly boosted the intervention effects. Similar results were sustained at 24 months. CONCLUSIONS: Although overall significant differences were not observed between intervention and control groups, the FAMILIA trial highlights that high adherence rates to lifestyle interventions may improve health outcomes. It also suggests a potential contributory role of the presentation of atherosclerosis pictures, providing helpful information to improve future lifestyle interventions in adults.AGENCIA FINANCIADORA: The American Heart Association, under grant No 14SFRN20490315, funded this study.

    A conceptual framework for crop-based agri-food supply chain characterization under uncertainty

    Get PDF
    [EN] Crop-based Agri-food Supply Chains (AFSCs) are complex systems that face multiple sources of uncertainty that can cause a significant imbalance between supply and demand in terms of product varieties, quantities, qualities, customer requirements, times and prices, all of which greatly complicate their management. Poor management of these sources of uncertainty in these AFSCs can have negative impact on quality, safety, and sustainability by reducing the logistic efficiency and increasing the waste. Therefore, it becomes crucial to develop models in order to deal with the key sources of uncertainty. For this purpose, it is necessary to precisely understand and define the problem under study. Even, the characterisation process of this domains is also a difficult and time-consuming task, especially when the right directions and standards are not in place. In this chapter, a Conceptual Framework is proposed that systematically collects those aspects that are relevant for an adequate crop-based AFSC management under uncertainty.Authors of this publication acknowledge the contribution of the Project 691249, RUC-APS "Enhancing and implementing Knowledge based ICT solutions within high Risk and Uncertain Conditions for Agriculture Production Systems" (www.ruc-aps.eu), funded by the European Union under their funding scheme H2020-MSCA-RISE-2015Alemany Díaz, MDM.; Esteso, A.; Ortiz Bas, Á.; Hernández Hormazabal, JE.; Fernández, A.; Garrido, A.; Martin, J....

    World Multidisciplinary Civil Engineering-Architecture-Urban Planning Symposium, WMCAUS 2016 -- 13 June 2016 through 17 June 2016 -- -- 132600As the fresh concrete waste has a high potential to damage the environment, current methods for the utilization of the returned ready-mixed concrete were presented throughout this study. Toward this aim, an in-depth literature review was performed as a methodological approach. Thus, types of the returned concrete were first explained and the existing methods were then discussed one by one. Consequently, the current methods were determined as (i) matching with suitable customers, (ii) blending with next matches, (iii) discharging into the settling basin, (iv) discharging onto the ground, (v) producing pre-cast concrete components, (vi) recycling mechanically, (vii) using the hardened slurry cake in concrete, (viii) using the hardened slurry cake in partition wall blocks, (ix) using hydration stabilizer admixtures, and (x) using superabsorbent polymer. © 2016 The Authors.MAG-113M428The authors acknowledge the financial supports provided by Committees on Research Grants of Akdeniz University and Bulent Ecevit University.
