Asprosin was a novel adipokine that was released by white adipose tissue. It was activated by fasting and attracted to the liver, which allowed the liver to rapidly release glucose into the bloodstream. White adipose tissue was the source of asprosin. When people go on a fast, their blood sugar levels drop, which causes levels of the hormone asprosin to rise. It does this by binding to a G-protein-coupled receptor in the liver known as OR4M1, which in turn activates a cascade that involves the G -protein-cAMP-PKA pathway. Because of this, the glucose that is stored in the liver is released.  We anticipate that by investigating the changes that occur in asprosin levels in hypothyroidism patients, we will be able to make a significant

By using a model that is derived depending on the first order perturbation theory, the rate constant at met/mol interface can be calculated with the calculated reorganization energy. The reorganization energy that is evaluated according to the outer sphere model is based on the electstatistics potential of the molecular donor and acceptor. The molecular parameters introduced in this model are the molecular weight, mass, density, and radius of molecule have been evaluated according to the apparent molar volume using spherical approach.       Th

In the present study, we intend to evaluate the effect of temperature on the structural, morphological, and optical properties of tin oxide. For this purpose, tin oxide micro-flowers were prepared by the hydrothermal method at two different hydrothermal temperatures of 130 and 150°C. The synthesized samples were investigated and characterized using X-Ray Diffraction (XRD), Field Emission Scanning Electron Microscopy (FESEM), Ultraviolet–Visible Spectroscopy (UV-Vis). The XRD results showed that the synthesized samples have single-phase crystallinity with a rutile structure. The mean crystallite size for synthesized Micro- flowers was calculated by the Debby-Scherrer equation and the values were 21 and 28 nm for 130 and 150°C respecti

Nuclear energy levels in  with modest occupancy of the fp-LS shell have been studied within shell model calculations. The interactions used to determine the nuclear energy levels are FPD6, KB3G, and FPY using the fp shell and d3f7cospn for 1d3/21f7/2 model space. Results are compared with each other, and with the existing experimental data, there is clear agreement with some results. Aside from the excellent agreements in the replicated values of energy levels scheme, using model space interactions is the best-fitted two-body matrix element in the fp shell model space. Particularly below 3MeV, the overall estimation of the replicated data is excellent. The wave vectors and analysis are represented in the so-called diagrammatic notation,

   A global scientific study found that reducing the excessive and indiscriminate use of antimicrobial medicinal drugs in all their forms significantly improved food safety. We made aqueous and organic extracts (Ex1, Ex2, and Ex3) from two plants (Origanum majorana and Matricaria chamomilla) to create the best alternative form for antimicrobial preventive agents that cause food spoilage. Traditional methods determined the most essential compounds in plants, and we used the FTIR analysis technique for all treatments to observe impurities such as glycosides, alkaloids, flavonoids, carbohydrates, and phenolic substances. This study points to synergistic activity for plant extracts (Origanum majorana and Matr

     In this paper, based on a linear relationship between the natural logarithms of the scale parameter and dose, nineteen models are constructed using the modified Weibull statistical model to describe the relationship of dose-response and time for multivariate dual-response life experiments with two-replicate. The real biological data set is considered to evaluate the response rates of breast cancer cells treated with the therapeutic zinc selenide prepared in two different ways (physically and environmentally/organically). The unknown parameters are estimated using two estimation methods. The mean square error is used to select the best model. The median lethal dose is then determined on the basis of a new formula at s

   The excessive and unwarranted use of pesticides at different stages of crop production can pose a great danger to the aquatic environment, and particularly to fish. Haematological parameters are indicated to be important for environmental pollution. Blood parameters respond to low doses of pollutants, so hematological changes in common carp fish are used for assessing the effects of contaminants. Toxicological effects of Goldate and Alexander individuals combined as a mixture were observed by monitoring hematological parameters in common carp fish. There were 3 concentration groups (1/10, 1/100, and 1/200) for every pesticide (Goldate, Alexander, and mixture of Goldate and Alexander)  exposed to juvenile fish (60–80 gm. in weigh

Recently, it has been revealed that Toxoplasmosis may be associated with some factors related to type 2 diabetes, such as glucose, insulin, the Homeostatic Model Assessment for Insulin Resistant (HOMA-IR), and Fatty acid binding protein (FABP). Therefore, the current study aimed to specify how Toxoplasma gondii (T.gondii) infection affects glucose, insulin, HOMA-IR, and FABP among adolescents. From October to December 2022, this study was carried out at Al Madain Hospital in Baghdad. For a group of adolescents visiting the hospital, an ELISA test was performed to check their anti-T.gondii antibodies. Ninety adolescents were selected to participate in the study on the basis of this examination. They were divided

Staphylococcus aureus is an extracellular and intracellular microbe that can infect different mammalian cells like epithelial, endothelial, and osteoblasts. It is a source of recurrent infection and has persistently caused a variety of human diseases, like skin infections and systemic diseases such as osteomyelitis, endocarditis, pneumonia, bacteremia, sepsis, and toxic shock syndrome. Diagnosed (30) isolates of S. aureus have been taken from urine. A clinical sample has been done according to the culture on mannitol salt agar and biochemical tests, then identification through amplification of the 16srRNA gene by conventional PCR, detection of spa and eap genes by conventional PCR found all isolated to

One of the main complications in patients with Diabetes Mellitus is diabetic foot ulcers (DFUs), a significant and common disease. The wound of a diabetic foot reduces  vascular supply and decrease host immune response, facilitating bacterial infection. The pathogen that is most commonly isolated in DFUs is Staphylococcus aureus. The purpose of this work was to identify S. aureus by conventional, biochemical, and molecular detection of the virulence factor genes in DFUs. This case cohort study was directed at Al-Hussein Teaching Hospital (AIsamawa, Iraq) and Medical City/Baghdad Hospital (Baghdad, Iraq) from January to July 2022, and it involved 140 patients with diabetic foot ulcers. Extraction of bacterial DNA from t

  The novel (La-PAA) of the ligand 8-[3-(pyrazoyl)azo]Adenine (PAA) was synthesized with the molar ratio (1:3), which was appointed by using the mole ratio method. The C.H.N.S elemental analysis, magnetic measurement, thermal analysis, and spectral methods (UV-Vis, FTIR, and HNMR) were employed to support the mode of binding and geometrical structure for ligand (PAA) and (La-PAA) complex. The FTIR and 1H N.M.R. spectral results showed that the (PAA) acts as neutral N, N-bidentate with La (III), as well as the absorption results in specific octahedral structures for (La-PAA) complex. The thermal decomposition of the (PAA) ligand and its (La-PAA) complex performed many steps, and the (La-PAA) complex is more thermal stable than the free l
