Abstract This study aimed to evaluate the association between the CLEC3A gene polymorphisms (rs2735401/rs2293776/ rs2072665) and the gastric cancer risk in the Northwestern Chinese population. A hospital-based case-control study was conducted on 681 cases and 756 healthy controls. Odds ratio (OR) and 95% confidence intervals (CI) were applied to evaluate the association of the CLEC3A polymorphisms on gastric cancer risk. We found that there was no significant association between the CLEC3A polymorphisms and gastric cancer susceptibility, which was detected in the main analysis or stratification analyses of age, gender, and clinical stages. Our findings verified that the CLEC3A polymorphisms are not… More >

Abstract Randomly amplified polymorphic DNA (RAPD) is a tremendously convenient approach used to discriminate between Brassica species owing to its accuracy and speed. RAPD primers generate adequate genetic information that can be used in the primer-marker system. In this work, twenty RAPD-PCR based markers were executed to generate polymorphic data, like polymorphic information content (PIC), mean resolving power (MRP), resolving power (RP), effective multiplex ratio (EMR), and marker index (MI) for the first time and genetic distance among and between six Brassica species were calculated. Our results indicated that 20 primers produced a total of 231 scored band and generated 87%… More >

Abstract Methylenetetrahydrofolate reductase (MTHFR) deficiency is the most common genetic cause of hyperhomocysteinemia, which has been implicated in the etiology of recurrent spontaneous abortion (RSA). This study was designed to investigate the association between two single nucleotide polymorphisms (SNP) (rs1801133 [C677T] and rs1801131 [A1298C]) in the MTHFR gene and RSA, in Saudis. These two SNPs were selected as these polymorphisms have a different effect on the activity and stability of the enzyme, and significantly diverse effects have been reported in relation to the association with RSA. Ethical approval was acquired from the IRB at King Saud University (KKUH), Saudi Arabia, and… More >

Abstract The use of medicinal plants for different therapeutic values is well documented in African continent. African diverse biodiversity hotspots provide a wide range of endemic species, which ensures a potential medicinal value. The feasible conservation approach and sustainable harvesting for the medicinal species remains a huge challenge. However, conservation approach through different biotechnological tools such as micropropagation, somatic embryogenesis, synthetic seed production, hairy root culture, molecular markers based study and cryopreservation of endemic African medicinal species is much crucial. In this review, an attempt has been made to provide different in vitro biotechnological approaches for the conservation of African medicinal… More >

Abstract This paper proposes a novel genetic algorithm (GA) that embeds a niche competition strategy (NCS) in the evolutionary flow to solve the combinational optimization problems that involve multiple loci in the search space. Unlike other niche-information based algorithms, the proposed NCSGA does not need prior knowledge to design niche parameters in the niching phase. To verify the solution capability of the new method, benchmark studies on both the travelling salesman problem (TSP) and the airline recovery scheduling problem were first made. Then, the proposed method was used to solve single nucleotide polymorphism (SNP) barcodes generation problems in a genetic association… More >

Abstract In this study, we used a meta-analysis method to evaluate the relationship between hypoxia-inducible factor-1α (HIF1α) 1772C/T gene polymorphism (rs 11549465) and renal cell carcinoma (RCC)/prostate cancer risk. We searched for relevant studies (before March 1, 2019) on Cochrane Library, Embase, and PubMed. Studies meeting the inclusion criteria were recruited into this meta-analysis. The outcome of dichotomous data was showed in the way of odds ratios (OR), and 95% confidence intervals (CI) were also counted. In this investigation, there was no association between HIF1α 1772C/T gene polymorphism and susceptibility to RCC in Caucasians, Asians as well as overall populations. In… More >

Abstract Residual ridge resorption (RRR) is the decrease in the jaw structure that follows tooth extraction. It is a multifactorial disorder, but reports on the associated genetic factors are scarce, particularly amongst the Saudis. This study aimed to investigate the role of single nucleotide polymorphisms (SNPs) in fibroblast growth factor receptor 1 oncogene partner 2 (FGFR1OP2) in RRR development in Saudis. The study included 192 individuals (RRR = 96; controls = 96) attending outpatient clinics at the College of Dentistry, King Saud University. Demographic and clinical data were collected, the digital panoramic dental radiograph was obtained, and mandibular residual ridge height… More >

Abstract Essential hypertension is considered a multifactorial trait resulting from a combination of environmental and genetic factors. The angiotensin II type 1 receptor mediates the vasoconstrictor and growthpromoting effects of Ang II. The A¹¹⁶⁶C polymorphism of the AT₁ receptor gene may be associated with cardiovascular phenotypes, such as high arterial blood pressure, aortic stiffness, and increased cardiovascular risk. We investigated the association between this A¹¹⁶⁶C polymorphism and hypertension in hypertense and normotense subjects from San Luis (Argentina) by mismatch PCR-RFLP analysis. Hypertense patients exhibited significant increases in lipid related values and body mass index. The frequency of occurrence of the C¹¹⁶⁶… More >

Abstract Genetically modified crops could cause negative effects on bacterial communities. In this study, we compared the bacterial community structure of two maize cultivars to determine whether the transgenic cultivar exerts a negative effect on bacterial communities inhabiting the rhizosphere. Cultivars included the genetically modified maize (Zea mays), with the pat-gene conferring resistance to the herbicide glufosinate (synonym: L-phosphinothricin), and the hybrid, conventional maize. Metagenomic DNA was extracted from the rhizosphere of plants grown in a greenhouse. Single-strand conformation polymorphism, based on polymerase chain reaction amplifying a partial subunit rRNA gene was used to characterize and generate genetic profiles that corresponded… More >

Abstract To quantify the effect on genetic diversity of restoring tree populations in an area under the influence of an urban heat island, we evaluated the genetic diversity of 72 Ceiba aesculifolia individuals, from a restoration experiment established from 2170 to 2260 m a.s.l. Reintroduced individuals were compared with the provenance from which the seeds were obtained, and two external provenances, for a total of 123 individuals. Samples were analyzed with three AFLP primer combinations. Polymorphisms of 38.4 to 62.5% were obtained. Genetic diversity estimated with the Simpson index ranged from 0.14 to 0.2. The provenances in the restoration site had… More >
