Different strains selected as biological models...
A series of cobalt-inserted copper zinc ferrites, Cu0.6CoxZn0.4−xFe2O4 (x = 0.0, 0.1, 0.2, 0.3, 0.4) having cubic spinel structure were prepared by the coprecipitation method. Various characterization techniques, including XRD, FTIR, UV-vis and I–V used to investigate structural optical electrical properties, respectively. The lattice constant was observed be decreased as smaller ionic radii Co2+ (0.74 Å) replaced higher Zn2+ (0.82 Å). presence tetrahedral octahedral bands confirmed FTIR...
Epstein Barr Virus (EBV) is implicated in the carcinogenesis of nasopharyngeal carcinoma (NPC) and currently associated with at least 1% global cancers. The differential prognosis analysis NPC EBV genotypes remains to be elucidated. Medical, radiological, pathological, laboratory reports 146 patients were collected retrospectively over a 6-year period between 2015 2020. From pathology archives, DNA was extracted from tumor blocks used for nuclear antigen 3C (EBNA-3C) genotyping by nested...

In December 2019, the city of Wuhan, located in Hubei province China became epicentre an outbreak a pandemic called COVID-19 by World Health Organisation. The detection this virus rRTPCR (Real-Time Reverse Transcription-Polymerase Chain Reaction) tests reported high false negative rate. manifestations CXR (Chest X-Ray) images contained salient features virus. objective paper is to establish application early automated screening model that uses low computational power coupled with raw...
Copper oxide nanoparticle (CuO-NPs) attracts the attentions of human beings due to unique physicochemical and biological properties. The chemical green synthesis approaches were used CuO-NPs plant leaves extract Azadirachta indica (A. indica) was preferred in approach. XRD analysis analyze monoclinic crystal structure calculate average crystallite size range 15 ∼ 16 nm. While, information about different rotational vibrational modes attached on spectrum identified by FTIR. After that UV–VIS...
Coronavirus (COVID-19) outbreak from Wuhan, Hubei province in China and spread out all over the World. In this work, a new mathematical model is proposed. The consists system of ODEs. developed describes transmission pathways by employing non constant rates with respect to conditions environment epidemiology. There are many models purposed scientists. model, "αE" "αI", coefficients exposed cases susceptible infectious respectively, included. "δ" as governmental action restriction against...
Since the initial emergence of Middle East respiratory syndrome coronavirus (MERS-CoV) in 2012, a high incidence rate has been observed Saudi Arabia. This suggests that country is at continuous risk. The epidemic level MERS-CoV infection was examined Arabia by Susceptible-Infectious-Recovered (SIR) model using Bayesian approach for estimation time dependent reproduction number (R) across two-year interval (May, 2013-May, 2015) five defined clusters, followed sensitivity analysis most...
Graphene-based materials have garnered significant attention because of their versatile bioapplications and extraordinary properties. Graphene oxide (GO) is an extremely oxidized form graphene accompanied by the functional groups oxygen on its surface. GO outstanding platform which to pacify silver nanoparticles (Ag NPs), gives rise oxide-silver nanoparticle (GO-Ag) nanocomposite. In this experimental study, toxicity nanocomposites was assessed in vitro human breast cancer model optimize...
Dye sensitized solar cells (DSSCs) are attracting immense academic and industrial attention as a simple, low cost potential photovoltaic device from last two decades. In DSSC, photo-electrode is suggested an important component which collects well transports the photo-excited electrons sensitizer dye to external circuit. this research, photoanodes of 1% copper doped Titanium dioxide (Cu-TiO2) have been prepared by doctor blade method on FTO-glass substrates.

The regular monitoring of water environments is essential for preventing waterborne virus-mediated contamination and mitigating health concerns. We aimed to detect human adenovirus (HAdV) in the Wadi Hanifah (WH) Namar (WN) lakes, King Saud University wastewater treatment plant (KSU-WWTP), Manfouha-WWTP, irrigation (IW), AnNazim landfill (ANLF) Riyadh, Saudi Arabia. HAdV hexon sequences were analyzed against 71 prototypes investigated seasonal influence. ANLF had highest prevalence (83.3%)....
Respiratory infections are caused by an array of viruses, and limited information is available about viral coexistence, comparative symptoms, the burden illness.
