Electrochemical DNA-nano biosensor for the detection of Goserelin as anticancer drug using modified pencil graphite electrode.

Goserelin is an effective anticancer drug, but naturally causes several side effects. Hence the determination of this drug in biological samples, plays a key role in evaluating its effects and side effects. The current studies have concentrated on monitoring Goserelin using an easy and quick DNA biosensor for the first time.

CdInSe@chitosan heterojunction nanocomposite with ultrahigh photocatalytic activity under sunlight driven photodegradation of organic pollutants.

This research focused on synthesizing a CdInSe@Ch nanocomposite by doping CdInSe into chitosan using a photolysis assisted ultrasonic process. The aim was to enhance the photodegradation efficiency of ofloxacin and 2,4-dichlorophenoxyacetic acid under sunlight. The synthesized CdInSe@Ch nanocomposite was investigated via different techniques, including XRD, XPS, FTIR, TEM, DSC, TGA, UV-Vis and PL.

Methanol extract of Iraqi Kurdistan Region as a potent source of antioxidant, antimicrobial, and anticancer agents for the synthesis of novel and bioactive polyvinylpyrrolidone nanofibers.

In this study, aqueous, ethanol, methanol, and hexane extracts from Iraqi Kurdistan Region Daphne mucronata were prepared due to the numerous applications and development of nanofibers in biological and medical fields, including food packaging, enzyme stabilization, and wound dressing. In the initial evaluation of the extracts, the antioxidant properties against DPPH, antimicrobial properties against 3-gram-positive bacterial species, 3-gram negative bacterial species, 3-common bacterial species between aquatic and human, and 3-fungal species, and anticancer properties against breast cancer cells were performed. The results proved that the methanol extract has the highest antimicrobial, antifungal, antioxidant, and anticancer properties.

Prevalence, Haematological and Molecular Studies of Isolated from Goat at AL-Muthanna Province, Iraq.

Parasitic infections, especially helminthes infections of the gastrointestinal tract due to the latent symptoms, play a vital role in the growth and efficiency of ruminants. The current research was performed to determine the prevalence of haemonchosis in goats and the effect of some risk factors, such as age, sex, and months on the infection rate. Also, our study includes investigating the haematological and biochemical changes in the haemonchosis-infected goat, then utilizing the PCR technique to confirm the diagnosis in goats.

Comparison between Antimicrobial and Antibiofilm Activity of Exopolysaccharides (EPS) Extracted from and against Oral Bacteria.

Due to the increased resistance to antibiotics and chemical biocides, the use of bacterial exopolysaccharides has been considered. The objective of the current study was to investigate the strength of the antibacterial and antibiofilm activity of EPS extracted from and because previous studies showed there were structural differences between EPS, during this study, EPS extracted from and by ethanol precipitation method and estimated antibacterial and antibiofilm activity against several Oral Bacteria (, , , , in different concentration as (100,150,200,250,300 mg/ml ), the results showed carbohydrates rate in extracted EPS from and were recorded was 85, 80 % respectively.The concentration 100 and 150 mg/ml for EPS from and , there was no inhibitory effect, except in (1.

Histopathological and immunological study of rats liver hydatid cysts isolated from human, sheep, goat and cows.

In endemic places, liver hydatidosis is a life-threatening health issue. Many consequences such as hepatomegaly, infiltration with inflammatory cells and histopathological changes might arise as a result of liver hydatidosis. This study aimed to look into pathogenic changes in the livers of the rats that experimentally infected with hydatid cysts.

Effect of laser irradiated silver doped polystyrene/polyethylene terephthalate (PET) thin film for solar cell applications.

In the current research, the resist action of silver-doped polystyrene/polyethylene terephthalate (PET) solar thin film towards laser irradiation was observed. Moreover, silver-doped polystyrene nanoparticles were synthesized a chemical technique while the PET film was purchased from the commercial market. Nd:YAG pulsed laser has been used to irradiate the samples at 2 minutes, 4 minutes, and 6 minutes respectively.

Fouling resistance investigations of seaweed products.

Any solid, unprotected, and undefended surface in the aquatic environment will be fouled. Fouling, on the other hand, can affect a wide range of species that can tolerate some epibiosis. Several others, on the other hand, aggressively keep the epibionts off their body surface (antifouling).

Effects of Strontium on the Structural, Optical, and Microwave Dielectric Properties of BaTiO Ceramics Synthesized by a Mixed Oxide Route.

Solid solutions of Sr-doped barium nonatitanate (BaTiO) ceramics were synthesized by a mixed oxide route, studied their structural, microstructural, optical, and microwave dielectric properties were studied. X-ray diffraction (XRD) has been used to reveal the structure and crystallite size of doped BaTiO ceramics. Rietveld refinements of XRD patterns revealed that all of the ceramics have a tetragonal structure with space group 4/.

High prevalence of an alpha variant lineage with a premature stop codon in ORF7a in Iraq, winter 2020-2021.

Since the first reported case of coronavirus disease 2019 (COVID-19) in China, SARS-CoV-2 has been spreading worldwide. Genomic surveillance of SARS-CoV-2 has had a critical role in tracking the emergence, introduction, and spread of new variants, which may affect transmissibility, pathogenicity, and escape from infection or vaccine-induced immunity. As anticipated, the rapid increase in COVID-19 infections in Iraq in February 2021 is due to the introduction of variants of concern during the second wave of the COVID-19 pandemic.
