The contamination factor (Fc), the contamination degree (Dc), and heavy metal pollution index (HPI) were the models evaluated in aim to estimate the groundwater quality and the potential sources of trace metallic-elements infection. The concentrations of both Cd and Pb have been found to be below the permissible referred limits of drinking water quality standards, while Zn concentration exceeded the standards in most of the sampling points (eleven wells have Zn level > 15 ppb). The HPI of groundwater has been found to be far below the permissible limit of 100 (HPI = 40.6). Our obtained results give the assumption that the contamination of the studied groundwater is with limited extent, despite the prolific use of fertilizers and the intensive spill of industrial and domestic wastes in the ecosystem. Therefore, the low HPI values, noticed in the study zone, are likely attributed to the impermeability of geological formation preventing thus contaminants reaching the aquifer.","PeriodicalId":175657,"journal":{"name":"Advanced Research in Life Sciences","volume":"243 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124679715","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among the challenges to its production is the scarcity and high cost of broodstocks and sacrifice of the male during induced breeding. Cryopreservation of the milt of the species is a solution to this challenge. However, cryopreservation success depends on right extender, cryoprotectant and concentration. Phosphate buffered solution (PBS) and freshwater ringer solution (extenders), Dimethyl sulphoxide (DMSO), glycerol and glucose (cryoprotectants) at 5% and 10% concentrations were used to investigate the best cryoprotectants, cryoprotectant concentrations and extenders for short term cryopreservation of Clarias gariepinus milt. Control using fresh milt was also set up. Fifteen each of matured male and female broodstocks of C. gariepinus, weighing between 1.1 – 2.0kg were used for the experiment. analysis of variance (ANOVA), followed by comparison of means using Duncan’s Multiple Range Test. Percentage data were calculated prior to analysis. All statistical analyses were performed using SPSS software (Version 16.0, 2005). Dimethyl sulphoxide + phosphate buffered solution (DP) had the highest fertilization rate of 65% and 78% for 5 and 10% cryoprotectant concentrations respectively. Lowest fertilization rate was in glucose + freshwater ringer solution (GF) with 5 and 10% concentration giving 5% and 8% fertilization. Fertilization in control was 88%.

The biological value of food products enriched with herbal ingredients is getting more popular among consumers. The present study was aimed to evaluate microbiological quality of grape juice enriched with medicinal plants. There were two varieties of grapes -Welschriesling and Cabernet Sauvignon and six species of medicinal plants used for the experiment: Calendula officinalis L., Ginkgo biloba, Thymus serpyllum, Matricaria recutita, Salvia officinalis L., and Mentha aquatica var. citrata. A total of 14 samples of juice were prepared and two of them were used as controls and 12 samples were treated with medicinal plants. Total microbial count, coliforms, lactic acid bacteria and yeasts and microscopic fungi for testing the microbiological quality were detected. All the samples were negative for lactic acid bacteria. There were neither coliform bacteria nor yeast and fibrous microscopic fungi present in some of the treated samples apart from the control samples. Coliform bacteria of 1 log cfu/mL were detected during the first testing and identified Proteus vulgaris in the control sample of grape juice of the variety Welschriesling. The yeast of the genus Candida was present in 2 log cfu/mL and it was detected during first and second testing in the control sample of Cabernet Sauvignon, unlike the other samples. The sample of grape juice with the addition of sage had the most significant inhibitory effect on total count of bacteria. The most common microorganisms in all samples were Bacillus cereus and Acinetobacter johnsonii, however, those microorganisms were absent during second testing due to the action of naturally occurring antimicrobials in the grapes.","PeriodicalId":175657,"journal":{"name":"Advanced Research in Life Sciences","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126539599","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For this purpose, 190 improved strain chicks of one day-old with an average weight of 35.49±3.78g were distributed according to the type of feather. They were fed an iso-energetic and iso-proteic feed. Data on phenotype characteristics, growth performance, biometric data and carcass were determined. The main results show that three types of feathering were recorded with 16.4% of hens with bare necks and with feathered pits, 78.1% of hens with feathered pits and 5.5% of hens with normal feathers. The majority of hens were recorded with a single comb (75.3%), round mumps (71.2%), white pits (76.4%), black beaks (47.9%) and brown eyes (75.3%). In terms of zootechnical performance, the highest live weight (1758.00±322.20g) was recorded with naked-necked hens and feathered pits. The highest weekly average weight gain was recorded with yellow eyed hens (111.77±16.63g) followed by bare-necked and feathered pits (107.83±20.06g). Hens expressing the Na and Pti genes showed the best growth performance although carcass yield was not significantly affected by feather type. It was concluded that there is a very high phenotypic diversity in the so-called improved hens. However, despite their great potential, responsible management of this genetic resource should be encouraged in order to avoid genetic erosion of local poultry resources.","PeriodicalId":175657,"journal":{"name":"Advanced Research in Life Sciences","volume":"55 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121004139","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The K content presented an important increase from 7.7 mg/ml in the maturity with a value of 30 mg/ml. The average values of crude fiber content varied from 8.4 to 16.6. These values increase significantly with the development of the barley in different stages. The phytic acid content in the fourth stage (maturation) was 8.96±0.56 mg/g DM, and the proline content was very low in the first stage with a value of (2.474 ± 0.069) mg/ml DM and in the maturation stage the value was high with a value of (7.148 ± 0.248) mg/ml DM. The optical observation of the different microstructures and progressive changes that were undergone from the first filling stage of the mid-milk stage, soft dough stage, physiological stage, and ripening stage were studied. By optical observation, there is the formation of the first protective envelope of the grain, so all the tissues of the external pericarp that is grouped with the testa. The aleurone layer was structured in three rows with an important condensation of the cells of the albumen sub-structures that are involved in the storage.","PeriodicalId":175657,"journal":{"name":"Advanced Research in Life Sciences","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121501968","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
