Therefore, this study targeted to inspect the beneficial effects of LC and QT to defend againstameliorate ATZ toxicity through studying their effects on body weight, body weight gain, and hemogram in adult male rats. In light of this, four groups of seven adult male albino rats were established. The groups were control, ATZ, ATZ + LC and ATZ + QT and the experiment lasted for 56 days. Results showed no significant impacts on body weight (P > 0.05) in all groups. Additionally, compared to control group, ATZ dramatically decreased body weight gain (BWG) (P < 0.001). Moreover, rats that got ATZ plus the other treatments also showed a reduced BWG (P < 0.001). Moreover, ATZ intensely decreased the proportion and concentration of Hb, RBCs, WBCs and platelets counts (P < 0.001). Notably, administering LC restored Hb concentration and percentage, RBCs, WBCs and platelets counts to control levels (P < 0.01). Furthermore, Hb concentration and percentage were enhancedincreased numerically with QT. While ATZ reduced RBC, WBC, and platelet counts, QT markedly increased those counts (P < 0.01), though it did not bring them back to control levels.

Increasing wheat productivity is essential to reduce the food gap in Egypt. Applying modern biotechnological plant breeding techniques could create new, highly productive cultivars. Tissue culture is a powerful tool that can be used to facilitate genetic transformation, induce genetic variation in plants, and create new and improved crop cultivars. The present study examines in vitro callogenesis expression and regeneration capacity of wheat cultivars in controlled laboratory conditions. Seeds from ten modern Egyptian commercial cultivars (Five durum and Five bread wheat cultivars) were collected for in vitro studies. Two different explants (immature embryos and mature embryos) and different media supplemented with different plant growth regulators were used to test the best wheat callus formation protocol. Immature embryos showed the highest callus formation value on MS medium supplemented with 2 mg/l 2,4-Dichlorophenoxy acetic acid, while mature embryos showed the highest callus formation value on MS medium supplemented with 3 mg/l 2.4-D. All 2,4-D supplemented media exhibited increased callus induction, suggesting that the 2,4-D as an effective growth regulator. The results of this study with modern Egyptian cultivars demonstrated that the response to tissue culture is greatly influenced by the genotype, the type of nutrient medium, and the interaction between them. The most effective explant source for callus indication and plant regeneration is immature embryos.","PeriodicalId":516676,"journal":{"name":"Journal of Modern Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141694489","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}

This study aims to design and implement such a system to provide accurate and timely crime data, enhancing the ability to track criminals and improve overall crime management. The proposed system integrates data from various police stations into a central database, enabling quick access and efficient resource allocation. By automating the documentation and retrieval processes, the system addresses issues such as poor data storage, loss of important information, and slow response times. The system captures detailed information about crime suspects from the initial report to court prosecution, supporting decision-making and trend analysis. Microsoft Visual Basic programming language and Microsoft Access database were used to develop the system, chosen for their user-friendly interface and robust data management capabilities. Rigorous testing was conducted to ensure functionality and performance, with unit testing of individual components and system testing of the entire setup. The implementation of this computerized system demonstrates significant improvements in managing and utilizing crime data compared to the manual methods, offering a robust tool for enhancing law enforcement efficiency and public safety in Nigeria.","PeriodicalId":516676,"journal":{"name":"Journal of Modern Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141705571","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 results revealed notable differences in callus induction and its fresh and dry weights between the two Moringa species ( M. oleifera and M. stenopetala ), as well as among MS media used. Furthermore, the study demonstrated significant variations in response of two tested explants (leaves and hypocotyls). Active meristematic cells were classified into three types: Type I includes dividing cells, Type II consists of meristematic cells with diffused chromatin, and Type III represents cylindrical cells with diffused chromatin.

The primary treatment approach involves achieving complete surgical removal, whenever feasible, utilizing intraoperative monitoring and neuronavigation. In cases where mandatory, a second surgery may be performed, ensued by adjuvant radiation therapy. Nevertheless, emerging proof suggests that certain ependymal tumors can be successfully treated with surgery only, whilst others may experience relapse despite adjuvant therapy. The function of chemotherapy remains unclear at present. Current therapeutic strategies yield affordable survival rates for most patients with ependymoma. The next hurdle is to surpass initial tumor control by employing risk-adapted therapy, aiming to minimize secondary effects and therapy-induced morbidity for low-risk individuals, while intensifying treatment for high-risk individuals.

Results showed a significant effect of both investigated factors in herb day weight, seed yield, and proximate analysis. The highest seed yields (44.1 and 42.7 g/plant) with insignificant difference between them was for plants treated with 1.0 g/l of chitosan + (1 g/l tryptophan) or (3.0 g/l glycine) respectively. Whereas the minimum seed yield of about 21.2 and 21.7 g/plant was estimated for non-amino acid treated plants + 2.0 or 3.0 g/l of chitosan. The higher seed moisture content (5.37%) was for plants treated with 2 g/l of tryptophan in addition to 1.0 g/l of chitosan. Generally, increasing chitosan over 2.0 g/l caused a reduction in seed moisture content. Non-amino acid-treated plants that received 3.0 g/l of chitosan had the lowest ash (3.18%), but the highest value (4.63%) was for plants treated with 1.0 g/l chitosan + 1.0 g/l tryptophan. The lowest and highest lipids (28.11 and 30.75) were for untreated plants, and those treated with (2.0 g/l chitosan + 2.0 g/l tryptophan), respectively. Therefore, the study suggested that N. sativa plants could be treated with 1.0 g/l chitosan in addition to 1.0 g/l tryptophan to achieve the highest seed yield. However, for higher lipids content plants should be treated with 2.0 g/l of chitosan and 2.0 g/l tryptophan.","PeriodicalId":516676,"journal":{"name":"Journal of Modern Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141701162","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}

Fifteen polyphenolic compounds were identified by the HPLC analysis of P. rubra methanol leaves extract. Additionally, an in vitro cell viability test was used to assess the cytotoxic activity of the methanol leaves extract of P. rubra . The findings of the cytotoxicity test revealed substantial anticancer activity against the human lung carcinoma A-549 cell line with an IC 50 of 41.72 μg/ml and less activity against the human colon carcinoma HCT-116 and the human breast carcinoma MCF-7 cell line with IC 50 of 57.62 and 75.8 μg/ml, respectively.
