Pesticide residue in vegetables (tomatoes, cucumbers, and potato) from various markets in three areas at Minia Governorate were determined. Using modified (QuEChERS) method vegetable samples are extracted and determination by Gas Chromatography Mass Spectrometry (GCMSMS).The results showed a strong correlation coefficient (≥ 0.992 ) within the detected residues that in a range of 10 to 1000 ng / g-1, along with a recovery rate between 64.4 to 92.16 percent. While, the limit of quantification ranged from 10 to 50 ng / g-1, respectively. After analyzing 54 vegetable samples, the pesticides residues were detected in 66.66 % percent of the samples. The detection limits lies between 0.0019 and 0.028 ng/gm-1. Residues of various pesticides were chlorofenpyer, and chloropyrifos ( with frequency 18/54) followed by imidichlopride, azoxystrobin, (16/54) propagate (15/54), followed with lufenuron (11/54) and dimethemoroph (12/54); carbendazim, thiophinate methyl, metalaxyl, and cyhalothrin ( 9/54) while as difenconzole, omethoate and methomyl were frequented ( 6/54) respecively. The least frequent pesticides were indoxicarb, cymoxanyl, cyfalothrin and acetampride in vegetables from various markets in three different locations at winter 2021 and summer 2022. Chlofenpyer, propargite, chloropyrifos, Carbendazim – lufenoron, and cypermethrin) were found in 44.67% of the vegetable samples hand were more than MRLs., while the other pesticides detected not exceeded the MRLs. Risk ratios were computed and the findings indicate that residues of chlorpyrifos, propagrite, and methomyl from 48 pesticides tested are the most significant commodity contributing to the hazard index (HI) more than 100% and pose a severe public health risk.

Atrazine (ATZ) is one of the most extensively used herbicides globally. It is classified as an endocrine disruptor chemical (EDC), interfering with several physiological functions. L-carnitine (LC) and quercetin (QT) have been shown to have significant antioxidant actions. 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. There were no discernible changes (P > 0.05) between the groups for the other hemogram parameters. Thus, LC and QT could be considered excellent candidates to abate the adverse effects of ATZ on hemogram.

Wheat is the most extensively cultivated and extremely nutritious cereal crop in the world. 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.

The inefficiencies of manual crime tracking systems in Nigeria necessitate the development of a computerized crime tracking information system. 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.

The significance of Moringa lies in its diverse advantages, encompassing nutritional richness, medicinal properties, and potential environmental sustainability. The current study sheds light on the impact of explant type and medium composition on callus and shoot induction of two Moringa species cultivated in Egypt. Additionally, it investigates certain cytological features in root tip cells of those plants as well as cells of induced calli in vitro, such as cell shape, size and mitotic activity. 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. Interestingly, the percentages of dividing cells may suggest the mitotic index (MI), with the MI being considerably higher in cells of M. oleifera compared to M. stenopetala.
辣木的重要意义在于它具有多种优势，包括丰富的营养、药用特性和潜在的环境可持续性。目前的研究揭示了外植体类型和培养基成分对埃及栽培的两种辣木的胼胝体和芽诱导的影响。此外，本研究还调查了这些植物根尖细胞以及体外诱导胼胝体细胞的某些细胞学特征，如细胞形状、大小和有丝分裂活性。结果表明，两种辣木（M. oleifera 和 M. stenopetala）在胼胝体诱导及其鲜重和干重方面存在明显差异，所使用的 MS 培养基也不尽相同。此外，研究还表明，两种受测外植体（叶片和下胚轴）的反应存在显著差异。活性分生细胞被分为三种类型：I 型包括分裂细胞，II 型由染色质弥散的分生细胞组成，III 型代表染色质弥散的圆柱形细胞。有趣的是，分裂细胞的百分比可能暗示了有丝分裂指数（MI），与 M. stenopetala 相比，M. oleifera 细胞的有丝分裂指数要高得多。

Pediatric ependymomas encompass distinct tumor types characterized by variations in epigenetics, age distribution, localization, and prognosis. Histopathological features continue to hold relevance in risk stratification within these defined tumor types. 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. The recognition of specific variations may pave the way for targeted therapy, enabling personalized treatment approaches in the future.

Seeds of Nigella sativa , are considered as one of the vital forms of available healing treatment. A field experiment was carried out to investigate the effect of chitosan (0.0, 1.0, 2.0, and 3.0 g/l) and two individual amino acids; glycine and tryptophan (0.0, 1.0, 2.0, and 3.0 g/l) application on plant growth and productivity. 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.

Numerous polyphenolic compounds originating from plants are thought to have anticancer and apoptosis-inducing effects on cancer cells. Plumeria rubra (family Apocyanaceae) is utilized as traditional medicine to cure a variety of diseases. It is well known for being a decorative tree, broad cultivated, very fragrant, and having a wide range of secondary metabolites, which inspired us to learn more about its possible medical uses. In this work, the total phenolic content of the methanol extract of P. rubra was established spectrophotometrically and found to be 11.05 mg/g, while the total flavonoid content was found to be 29.22 mg/g. 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. Results of this work demonstrate that methanol leaves extract of P. rubra is a valuable source of phenolics and flavonoids that that can substantially slow the spread of cancer.

Aim: to achieve the surface roughness of bulk-fill composite resins based on ORMOCER and methacrylate. Materials and method: In this research, A total 24 specimens had been utilized in this work, were split to 2 groups (n=12) based on to the form of composite resin (Group I: bulk-fill composite resin based on ORMOCER and Group II: bulk-fill composite resin based on Methacrylate). Each group was subjected to surface roughness. Statistical analysis by, Mann-Whitney test to compare two groups, was utilized, then a Wilcoxon W test is performed. At p < 0.05, the significant threshold was established. A standardized cylindrical mold (polytetrafluoroethylene) had been utilized to fabricate the bulk-fill resin composite species which were examined prior and following wear stimulation and photographed utilizing a 3D-surface analyzing system. Results: The mean Ra scores of the Aura bulk fill composite samples' surfaces were greater comparing with that of the Admira fusion x-tra composite samples' surfaces, where Ra is a measure of the arithmetic mean of all profile deviations throughout the mean sampling length in μm. Following wear simulation, group II (Aura bulk fill) obtained the higher ΔRa mean value (0.0031±.0066 μm) followed by group I (Admira fusion x-tra) (0.0016± .0032 μm). Statistics showed that there was no variance across all groups (p > 0.05). Conclusion: Composites made of methacrylate and ORMOCER are both susceptible to surface roughness after aging and wear stimulation. Considering that Admira Fusion X-tra has the lower
目的：实现基于 ORMOCER 和甲基丙烯酸酯的批量填充复合树脂的表面粗糙度。材料和方法：本研究共使用了 24 个试样，根据复合树脂的形式分为两组（n=12）（第一组：基于 ORMOCER 的大量填充复合树脂；第二组：基于甲基丙烯酸酯的大量填充复合树脂）。每组都进行了表面粗糙度检测。统计分析采用 Mann-Whitney 检验对两组进行比较，然后进行 Wilcoxon W 检验。以 p < 0.05 为显著临界值。利用标准化的圆柱形模具（聚四氟乙烯）制作了大量填充树脂复合材料，在磨损刺激之前和之后对其进行了检查，并利用三维表面分析系统对其进行了拍照。结果：Aura 体积填充复合材料样品表面的平均 Ra 值大于 Admira 融合 x-tra 复合材料样品表面的平均 Ra 值。模拟磨损后，第二组（Aura 体积填充）的 ΔRa 平均值较高（0.0031±.0066 μm），其次是第一组（Admira fusion x-tra）（0.0016±.0032 μm）。统计显示，各组之间不存在差异（P > 0.05）。结论由甲基丙烯酸酯和 ORMOCER 制成的复合材料在老化和磨损刺激后都容易出现表面粗糙。考虑到 Admira Fusion X-tra 具有较低的
