Phyla nodiflora is a creeping perennial herb, which is widely used in folk medicine. The present study evaluates the phytochemical constituents and in vitro antioxidant and antibacterial potential of the aqueous leaf extract of Phyla nodiflora . The phytochemical analyses were carried out using standard methods. The antioxidant activity of aqueous leaf extract was investigated by using DPPH and total antioxidant activity. The antibacterial assay was determined using the agar well diffusion method against the Gram-positive and Gram-negative bacterial strains such as Staphylococcus aureus , Bacillus subtilis , Klebsiella pneumonia e and Pseudomonas aeruginosa using streptomycin as a positive control. The aqueous leaf extract of Phyla nodiflora was screened against Human Hepatocarcinoma (HepG2) cell lines to determine its anticancer activity. Phytochemical screening of aqueous leaf extract revealed the presence of steroids, flavonoids, carbohydrates, tannins, saponins and alkaloids. Aqueous leaf extract showed DPPH radical scavenging and total antioxidant activity with an IC 50 value of 45.91 µg/ml and 52.33 µg/ml. The highest zone of inhibition was found in K. pneumoniae (22.5mm), while P. aeruginosa (9.1mm) exhibited the lowest zone of inhibition, indicating that the leaf extract has significant antibacterial properties. The aqueous leaf extract of P. nodiflora exhibited significant antiproliferative activity against the HepG2 cancer cell line with an IC 50 value of 47.5 μg/ml. The increased apoptotic potential of HepG2 cells in a concentration-dependent manner was determined using the Acridine Orange/Ethidium Bromide assay. It has been concluded that the aqueous leaf extract of Phyla nodiflora possesses the potential for antioxidant, antimicrobial and anticancer activities.
野菜门是一种多年生匍匐草本植物,在民间医学中应用广泛。本研究对野菜叶水提物的植物化学成分及其体外抗氧化和抗菌活性进行了评价。植物化学分析采用标准方法进行。采用DPPH法和总抗氧化活性法研究了水提物的抗氧化活性。以链霉素为阳性对照,采用琼脂孔扩散法对革兰氏阳性和革兰氏阴性菌株金黄色葡萄球菌、枯草芽孢杆菌、肺炎克雷伯菌和铜绿假单胞菌进行抑菌试验。对野花门叶水提物进行抗人肝癌(HepG2)细胞株的筛选,以确定其抗肿瘤活性。叶水提物的植物化学筛选显示存在类固醇、类黄酮、碳水化合物、单宁、皂苷和生物碱。水提液具有清除DPPH自由基和总抗氧化活性,ic50值分别为45.91µg/ml和52.33µg/ml。对肺炎克雷伯菌(22.5mm)的抑制区最高,对铜绿假单胞菌(9.1mm)的抑制区最低,说明该叶提取物具有显著的抑菌作用。野茅叶水提物对HepG2癌细胞具有显著的抗增殖活性,其ic50值为47.5 μg/ml。用吖啶橙/溴化乙啶法测定HepG2细胞凋亡电位的增加呈浓度依赖性。结果表明,野茅叶水提物具有抗氧化、抑菌和抗癌活性。

parameters of Tetranychus urticae Koch of two ornaments plants Marshmallow and Salvia treated with four doses of gamma radiation 15, 25, 35 and 45 Kilo rad was studied under laboratory conditions at 25 ± 2°C, 65% RH. The results indicate that applied of gamma radiation had a significant effect on the duration of male and female feeding on salvia and Marshmallow leaves irrigated. The life cycle and generation period of irradiated females increased with increasing doses of gamma radiation and were significantly higher than the control. The female oviposition and longevity periods of T. urticae significantly increased with an increased dose of gamma radiation. The mean fecundity and daily rate significantly decreased with increasing doses of gamma radiation on salvia and marshmallows. A significant positive correlation was found between all immature stages, generation, and oviposition periods and the dose of gamma radiation. The Intrinsic rate of increase (r m ) and net reproductive rate (R 0 ) of T. urticae was the lowest at 45 Kilo rad (0.148 female/female/day and 20.59 female/female) and the highest value was found at control (0.256 female/female/day and 44.70 female/female), respectively on salvia leaves. The radiation of salvia and Marshmallow seeds reduced the fecundity of T. urticae females and prolonged the generation time than in control.
在25±2°C, 65% RH条件下,研究了棉花糖和鼠尾草两种装饰植物在15、25、35和45 Kilo rad辐照下的荨麻疹叶螨科赫参数。结果表明,γ辐射对灌水鼠尾草叶和棉花糖叶的雌雄取食时间有显著影响。受照雌鼠的生命周期和生育周期随γ辐射剂量的增加而增加,且显著高于对照组。随着γ辐射剂量的增加,荨麻疹雌虫的产卵期和寿命明显延长。随着γ辐射剂量的增加,鼠尾草和棉花糖的平均繁殖力和日产卵率显著降低。所有未成熟阶段、产卵期和产卵期均与γ辐射剂量呈显著正相关。在鼠尾草叶片上,45 kg / rad时,斑夜蛾的内在增殖率(r m)和净繁殖率(r 0)最低,分别为0.148雌/雌/d和20.59雌/雌),对照时最高,分别为0.256雌/雌/d和44.70雌/雌。鼠尾草和棉花糖种子辐照后,玉米螟雌虫的繁殖力降低,世代时间延长。

obligate intracellular protozoon, is transmitted by hard ticks and induces moderate to severe diseases in vertebrate hosts. The hard ticks Hyalomma dromedarii and Hyalomma anatolicum were collected from a camel in Saudi Arabia in October 2021. A total of 140 dromedary camels were selected by a simple random selection procedure. A total of 310 two different ixodid tick species, such as H. dromedarii and H. anatolicum were identified in camels. The infection rate of H. dromedarii was 78 % (242 /310) and that of H. anatolicum was 22% (68 /310). To identify H. dromedarii and Theileria sp. , polymerase chain reaction (PCR) using the COI gene and the 18S rRNA gene was done . The PCR-amplified 660-bp-long H. dromedarii and 400-bp-long Theileria sp. genes were analyzed with phylogenetic trees. H. dromedarii had a single genotype that was completely the same as that registered for H. dromedarii . The genotype of Theileria sp. found in H. dromedarii was highly similar to T. annulata by (99.9) %. This study may contribute to understanding the epidemiology of tick-borne diseases, thus, enhancing the detection and control of the diseases in Saudi Arabia.

Objective: The objective was to evaluate the effects of varying grades of insect-formulated feeds (IFF) on finishing-phase performance and nutrient retention of caged Cobb broilers. Materials and Methods: Cobb broilers (n=1050) were randomly assigned 50 per treatment in triplicates to African palm weevil (APW), housefly maggot (HFL) and Cockroach (CKR) formulated meals for six weeks respectively. Meals were formulated with larval stages of APW, HFL and adult CKR in single and combined forms, and commercial hybrid feed served as control. Birds were raised in an experimental animal house dimensioned 21.34-meter length by 3.05-meter breadth and divided into seven squared compartments. These seven compartments were further partitioned into three compartments each using wood, ply boards and net gauze which served as the triplicates for the experiment. Meals and water were served ad libitum and feeding was done twice daily. Weekly readings of body length, weight, breast width, feed efficiency and nutrient retention analysis were done using fecal samples. Results and Discussion: Growth performance increased weekly and was highest in broilers fed African palm weevil meals (p< 0.05). Nutrient retention equally increased (p< 0.05). The retention of dry matter, crude protein and calcium, ether extract, crude ash and phosphorus increased in housefly and African palm weevil and commercial hybrid feed respectively. Implications and Applications: Using these insects can result in improved performance and greater nutrient retention; however, an increased number of weeks is required to assess more growth performance. A formulated feed meal of African palm weevils could be adopted as a viable alternative meals for commercial production of broiler meat.
目的:研究不同等级昆虫配方饲料对科布肉鸡育肥期生产性能和营养物质保留的影响。材料与方法:选用科布肉鸡1050只,每处理50只,分3组,分别饲喂非洲棕榈象(APW)、家蝇蛆(HFL)和蟑螂(CKR)配制的饲粮,饲喂6周。以APW、HFL和成虫CKR幼虫期为单独和组合配制饲料,并以商品杂交饲料为对照。鸟类饲养在一个长21.34米,宽3.05米的实验动物舍中,分为7个方形隔间。这七个隔间被进一步划分为三个隔间,每个隔间使用木材,合板和网纱作为实验的三倍。食物和水是随意供应的,每天喂食两次。使用粪便样本进行体长、体重、胸宽、饲料效率和营养保留分析的每周读数。结果与讨论:肉仔鸡的生长性能以周为单位提高,其中以非洲棕榈象粕的生长性能最高(p< 0.05)。营养物质潴留显著增加(p< 0.05)。家蝇、非洲棕榈象鼻虫和商品杂交饲料中干物质、粗蛋白质和钙、粗脂肪、粗灰分和磷的滞留量分别增加。意义和应用:使用这些昆虫可以提高生产性能和更大的营养保留;然而,需要增加的周数来评估更多的生长表现。非洲棕榈象鼻虫的配方饲料粉可作为肉鸡肉商业生产的可行替代饲料粉。

how sperm DNA damage affects the patient reproduction ability. This suggests different outcomes, and the subject remains contentious. We investigated differences in sperm parameters and embryonic developmental steps in our study, and the observations compare the results of ICSI using sperm extracted from testicular on patients with high sperm injury to the results of patients with sperm DNA fragmentation on ejaculate samples. Materials and Methods: From March 2017 to December 2019, 418 couples were enrolled in our study at the Algazeera Centre for IVF Giza, Egypt. The parameters of the sperm were evaluated. The value sperm DNA fragmentation index (DFI) was calculated desponded on the sperm chromatin dispersion (SCD) diagnostic test, which was applied to teams in the regulation (sperm DNA fragmentation index < 30%) or abnormal (sperm DNA fragmentation index > 30%) groups. Results: decrease in fertilization and blastulation rate in a group of patients suffering high sperm damage on ejaculate samples and our results show no difference between normal ejaculate samples and testicular sperm extrication ( SDF) groups. Conclusion: no impact was detected on ICSI outcomes (pregnancy rates) between the three groups but a negative effect for sperm DNA fragmentation on fertilization and blastulation rate and blastulation rate depended on the age of women and the number of embryos transferred.
精子DNA损伤如何影响患者的繁殖能力。这意味着不同的结果,这个话题仍然存在争议。在我们的研究中,我们研究了精子参数和胚胎发育步骤的差异,并将精子高度损伤患者的睾丸提取精子进行ICSI的结果与射精样本中精子DNA断裂的结果进行了比较。材料与方法:2017年3月至2019年12月,418对夫妇在埃及吉萨的Algazeera试管婴儿中心参加了我们的研究。评估精子的各项参数。在精子染色质分散(SCD)诊断试验中计算精子DNA碎片指数(DFI)值,适用于正常组(精子DNA碎片指数< 30%)和异常组(精子DNA碎片指数> 30%)。结果:高精子损伤患者在射精样本上受精率和囊胚率下降,我们的结果显示正常射精样本和睾丸精子提取(SDF)组之间没有差异。结论:三组间对ICSI结果(妊娠率)无影响,但精子DNA片段化对受精和囊胚率有负面影响,且囊胚率取决于女性年龄和移植胚胎数量。

This suggests different outcomes, and the subject remains contentious. We investigated differences in sperm parameters and embryonic developmental steps in our study, and the observations compare the results of ICSI using sperm extracted from testicular on patients with high sperm injury to the results of patients with sperm DNA fragmentation on ejaculate samples. Materials and Methods: From March 2017 to December 2019, 418 couples were enrolled in our study at the Algazeera Centre for IVF Giza, Egypt. The parameters of the sperm were evaluated. The value sperm DNA fragmentation index (DFI) was calculated desponded on the sperm chromatin dispersion (SCD) diagnostic test, which was applied to teams in the regulation (sperm DNA fragmentation index < 30%) or abnormal (sperm DNA fragmentation index > 30%) groups. Results: decrease in fertilization and blastulation rate in a group of patients suffering high sperm damage on ejaculate samples and our results show no difference between normal ejaculate samples and testicular sperm extrication ( SDF) groups. Conclusion: no impact was detected on ICSI outcomes (pregnancy rates) between the three groups but a negative effect for sperm DNA fragmentation on fertilization and blastulation rate and blastulation rate depended on the age of women and the number of embryos transferred.","PeriodicalId":34551,"journal":{"name":"Egyptian Academic Journal of Biological Sciences B Zoology","volume":"38 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90123968","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}
