Wealth of information gleaned from decades high-impact research work; scientists have disentangled the complicated web versatile regulators that underlie cancer development and progression. Use structural biology approaches functional genomics helped us to gain new insights into complex nature cancer, it is now clear genetic/epigenetic mutations, overexpression oncogenes, inactivation tumor suppressors, loss apoptosis, versatility protein binding partners contributory roles in carcinogenesis...
Tetranychus urticae is an important pest of tomato crops globally, affecting plant yield and growth. Beauveria bassiana Metarhizium robertsii have the potential to control T. urticae. We investigated influence two B. (i.e., WG-12 WG-19) isolates one M. (WG-02) isolate when colonizing different organs (leaves, stems, roots) their on growth plants, through foliar, root-dipping, seed-soaking application techniques. also examined acaricidal activity three against (female adults), spraying leaf...
Herein, two‐shaped cerium oxide nanoparticles (NPs), that is, spherical and cubical, were synthesized through hydrothermal approach by tuning reaction temperatures. The morphology structural chemical composition of both samples characterized transmission electron microscopy (TEM), high‐resolution TEM (HRTEM), X‐ray diffraction (XRD), photoelectron spectroscopy (XPS), respectively. Both types NPs subjected to photodegradation industrial dye, methylene blue, under dark, sunlight, UV...
Abstract This study investigated the effect of heavy metals on Labeo rohita inhabiting Yamuna River, India. Levels measured in water were as follows: Fe>Mn>Zn>Cu>Ni>Cr>Cd. Gill and liver tissue exposed L. showed a high metal pollution index, compared to reference fish collected from Agra Canal. In fish, higher levels creatinine enzyme activity (alkaline phosphatase, aspartate aminotransferase, alanine aminotransferase) observed, while A:G index declined. Additionally, TLC,...
Abstract Water quality index (WQI) of Narora channel and health endemic fish Bagarius bagarius plant Eichhornia crassipes , district Bulandshahar, Uttar Pradesh, India were studied. Among the physicochemical properties water, pH, D.O, Cr, Fe, Ni, Cd above recommended standards. These factors lead to high WQI (4124.83), indicating poor not suitable for drinking domestic usage. In tissues, highest metal load was reported in liver (58.29) lowest kidney (33.73). Heavy metals also cause a...
A facile procedure for extracting and determining seven neonicotinoids was developed. Water the only extraction solvent without phase separation cleanup steps. The method validated according to European Union standards, values obtained were compared with criteria. accuracy between 99.8% (thiamethoxam) 106.8% (clothianidin) at spiking levels of 0.01, 0.1, 1 mg/kg in tested matrices. precision as pooled RSD ≤6.1% (intra-day) ≤6.9% (inter-day). limit quantification set 0.01 mg/kg. matrix effect...
Two genera, Anastatus Motschulsky and Eupelmus Dalman include more than half of the all species Eupelmidae (Hymenoptera: Chalcidoidea) world. is recorded for first time from Saudi Arabia through A. catalonicus Bolivar y Pieltain, 1935 and, bifasciatus (Geoffroy, 1785). Recorded also (Eupelmus) orientalis (Crawford, 1913). Key Words: Biodiversity, Anastatus, Eupelmus, parasititoids, new records
Two new and two known species of the genus Eudorylaimus belonging to family Qudsianematidae are described illustrated from Northeast China. Eudorylaimusblisterocaudatus sp. nov. is characterized by its 1.0-1.3 mm long body, lip region offset constriction 15-17 µm wide; odontostyle 1.0-1.2 times diameter long, odontophore 1.3-1.5 length, pharyngeal expansion occupying ~ 41-47% total neck length; V = 59-63%, uterus tripartite 1.3-3.8 corresponding body diameter, vulva post-equatorial, spicules...
Salinity is a significant abiotic stress that affects the growth, physiology, and yield of crop plants across globe. Sustainable measures to mitigate saline soil prevent losses require immediate attention. The present study aimed determine impacts hydrogel, biochar, biofertilizer on alfalfa growth physiological properties under salt stress. experiment was performed in randomized block design with three replications dried bottom Aral Sea, consisting control (T1), hydrogel alone (T2), biochar...
ABSTRACT Olive is a perennial tree able to grow and survive in Mediterranean conditions due its climate adaptations. In this study, we observed new disease characterised by leaf tip blight, shoot dieback olive trees the Southeast Anatolian region of Türkiye. Six fungal isolates were obtained from symptomatic trees. Classical methods based on macroscopic microscopic observations revealed that similar Sordaria macrospora . Total DNA was isolated PCR‐amplified with primer pairs for ITS , LSU...
Abstract Triazole fungicides may potentially harm human health. The ‘quick, easy, cheap, effective, rugged, and safe’ approach has become popular for extraction cleanup during pesticide residue analysis. We aimed to (a) validate a method the simultaneous determination of myclobutanil, penconazole, tebuconazole, triadimenol in squash using LC–MS/MS (b) determine pre‐harvest intervals (PHIs) assess related risk consuming cultivated under open‐field conditions Saudi Arabia. Using acetonitrile...
Abstract The date palm mite, Oligonychus afrasiaticus (McGregor) (Acari: Tetranychidae), is a serious pest of dates in the Middle East and North Africa, inflicting severe economic damage if not controlled early. As predaceous mites are known to be potential biocontrol agents against several pests, so predation capacity, life table, reproduction, survival Amblyseius swirskii Athias-Henriot Neoseiulus cucumeris (Oudemans) Phytoseiidae), collected from farms Qassim Saudi Arabia, were studied...
Abstract Cold stress has an immediate impact on plant structure and function. A large number of free radicals cause oxidative in plants. causes altered membrane permeability, lipid peroxidation, DNA damage. It denatures enzymes disrupts metabolism. Different methods are being investigated for acclimatizing plants subjected to cold stress. Nanobiotechnology bacterial strains growing agricultural strategies. Nanoparticles’ (NPs) unique qualities (small size, high mobility, biocompatibility,...
The developmental, survival, predation rates, and reproduction of Amblyseius swirskii (Phytoseiidae), as affected by feeding on the motile stages Phyllocoptruta oleivora (Eriophyidae) nymphs Eutetranychus orientalis (Tetranychidae), were studied in laboratory at six constant temperatures relative humidities: 9°C 70% RH; 16°C 65% 23°C 60% 30°C 55% RH, 37°C 50% RH 40°C 45% RH. maximum daily consumption rate was recorded occurred during oviposition period, when females consumed an average...
Maslinic acid (2α,3β-dihydroxyolean-12-en-28-oic acid) is a naturally occurring pentacyclic triterpenic compound. gradually gaining attention as an excellent pharmacologically active product because of its premium biological properties.
