Doxycycline is one of the tetracycline-class antibiotics used to treat bacterial and protozoan infections. The development method aimed to determine the Doxycycline hyclate in pharmaceutical drugs using a novel, rapid, and sensitive colorimetric-flow injection approach. The adopted method depended on forming a purplish violet colour complex for the doxycycline hyclate-ammonium chloroaurate reagent in an alkali medium, which a homemade SFI Analyzer measured. Both the physical and chemical variables were analyzed and improved. The calibration plot was linear in the 5-70 μg.mL-1 for the green light source, with a correlation coefficient r=0.9976 using the peak height of green light. The limit of detection was 0.5

     Melatonin (Mel) is a conserved chemical that has been found in far-removed evolutionary organisms. Additionally, it has been proposed that Mel is a stand-alone plant growth regulator whose action is presumably similar to that of IAA and may moderate the effects of other plant growth regulators. Twelve medicinal herbs were divided into parts, and their melatonin concentrations were measured. These plants Ziziphus spina-christi, , Eucalyptus comaldulensis, Melissa officinalis,  Alhagi maurorum, Lavandula angustifolia, Vitex agnus-sactus, Piper nigrum, Hordeum vulgare, Matricaria chamomilla, Borago  officinalis, Solanum lycopersicum and Citrus aurantium  . Methanol was used to extract melatoni

     Antibacterial substances belong to a group of compounds that attack dangerous microorganisms. Therefore, killing bacteria or reducing their metabolic activity will lessen their adverse effects on a biological system. They originated from either synthetic materials, microbes, or mold. Many of these medications treat the gram-negative bacteria from the critical precedence group, such as Pseudomonas, carbapenem-resistant Acinetobacter, and Enterobacterales. This study aims to investigate the simultaneous analysis of specific antibacterial spectrophotometrically. The WHO maintains this list of priority infections with antibiotic resistance. Drug combinations in single dosage forms are becoming increasingly popular in the pharmaceuti

In response to the water crisis, further research is necessary to comprehend the impact of human activities on nutrient concentrations in aquatic ecosystems, building on the extensive studies already conducted to understand these impacts on the water quality of various aquatic ecosystems. We hypothesized that human activities in the Tigris River's catchments could alter the nutrient concentrations in the water along the river. The results showed that phosphate concentration differed significantly among the studied sites due to distributed human activities, while nitrate concentration did not. Water temperature did not affect phosphate and nitrate concentrations. We concluded that human activities on the surrounding landscapes could be mo

     Diabetes mellitus (DM) is a chronic metabolic disorder characterized by persistent hyperglycemia. It may be due to impaired insulin secretion, resistance to insulin's peripheral actions, or both. The aim of this study was to estimate the percentage impact of obesity on the incidence of DM, as well as compare the levels of Apelin-36, glutathione-S-transferase, and insulin resistance (IR) in subjects with and without DM for both sexes. This study included 120 subjects, divided into 60 as a control group and 60 as a patient group of both sexes; all were adults between the ages of 30 and 65. The participants with fasting blood sugar, lipid profile, glycated hemoglobin (HbA1c), apelin-36, body mass index, insulin hor

Periodontitis is a common disorder caused by imbalanced plaque biofilms and associated with gradual deterioration of the teeth supporting apparatus. Obesity is documented as a significant health concern and considered a primary risk factor for the progression of many diseases, such as hypertension, diabetes, malignancies, and periodontitis. Proinflammatory cytokines released in response to these health conditions are of great importance and establish the link between diagnosis and treatment. The present study was conducted to assess levels of chemerin and visfatin in saliva and to evaluate the impact of obesity on periodontitis. Ninety participants were included in the study and dived into three groups: (Group I: obese and periodontitis

Sodium thiosulfate (STS) is a possible therapeutic candidate molecule in a range of diseases and drug-induced toxicities due to its antioxidant, anti-inflammatory, and anti-apoptotic capabilities. The current study aimed to find the effective dose of STS in adult male rats given nicotine by evaluating serum MDA and blood partial pressure of oxygen (PO₂) levels. Thirty-six adult male Wistar rats, Rattus norvegicus (weighing 190–220 g) with an age of 3–3.5 months,  were chosen randomly and separated into six equal groups, administered for 28 days. Animals in the control group were administered an intraperitoneal (i.p.) injection of normal saline, while those in groups 1, 2, 3, 4, and 5 received repeated doses of an

The effect of couple stress, slip condition, changing rotation, and other variables on the peristaltic flow of Powell-Eyring fluid in an inclined asymmetric channel with an inclining magnetic field through a porous media is investigated in this study. Constitutive equations obeying the Powell-Eyring fluid model are employed. In flow analysis, assumptions such as a low Reynolds number and a long wavelength approximation are used. The stream function and mechanical efficiency have closed form expressions devised. The stream function is expressed mathematically. Through the collection of figures, the impact of various criteria is explained and graphically represented Through the collection of figures, the impact has been explained of the Ha

An inherited tendency is necessary for the manifestation of celiac disease (CD), an autoimmune, gluten-sensitive, inflammatory disorder of the small intestine. Gluten, a storage protein in cereals, causes CD. An increase in oxidant compound generation, surpassing the capacity of the endogenous antioxidant system, causes oxidative stress (OS). This study aims to evaluate some oxidants and antioxidants factors in Iraqi females with CD. This hospital-based cross-sectional study at Baghdad Educational Hospital in Baghdad, Iraq, involved 100 female participants of reproductive age. Tests have been measured, such as total oxidants (TOS), total antioxidants (TAS), malondialdehyde (MDA), catalase (CAT), nitric oxide (NO), total protein (TP), and

With fear and Growly-Martin functional response have been established. It is observed that there is a trans critical and  pitchfork bifurcations near each of  , where as a saddle-node bifurcation near the positive equilibrium point have been occurred. Finally, numerical simulation was used to illustrate the occurrence of the bifurcation of the proposed model.

Crude oil is known globally as one of the major causes of environmental pollution. This chemical compound exerts exhausting impacts on cultivable lands and water surfaces, leading to profound damage to agriculture and aquatic life. Over the years, several bioremediation approaches have evolved to manage this pollution problem properly. A phylum of microorganisms known as cyanobacteria offers an efficient alternative to established bioremediation methods. We conducted the present study to investigate the effectiveness of cyanobacteria in eliminating residual total petroleum hydrocarbon (TPH). Synechococcus algae treated three concentrations of crude oil (0.6, 1.8, and 3 ppm) over four time periods (on days 3, 6, 9, and 12). The g

     Novel heterocyclic acid-base indicators 8-[3-(phenol)azo] theophylline (PAT) and 8[1-(6-sulfonic acid naphthalene) azo] theophylline (SAT) were synthesized through the reaction between m-amino phenol and 1-amino naphthalene -6-sulfonic acid with sodium nitrite to form the diazonium salt at a temperature 0-5˚C in an acidic medium, then a coupling process between the diazonium salt and theophylline compound to produce pigments at the same temperature while maintaining the PH level at 5-6. This study aims to prepare acid-base indicators based on azo dyes. The structural features of these indicators were examined via elemental analyses [FTIR, UV-Vis, and HNMR] spectroscopies, thermal analysis (TGA), and scanning el

     The problem of estimating the number of clusters k is considered one of the major challenges for partition clustering. The k-means algorithm is a division-based clustering method where only objects are entered into a set of K, and the algorithm decides the number group initially, but there is no specific way to estimate the best number for the cluster. The outcome of the clustering process can be better after being performed in more than one attempt. Therefore, the optimal count of iterations can be identified through a steady method in advance that can determine the time and number of rounds. So, the problem is finding the optimal number (k) in an easy and fast way. The aim of this paper is to use a genetic algorithm (GA) with

Thin films (CuxZn1-xS) with x = 0.75 nano crystallized were deposited from the alloy on glass substrates in a vacuum ~ 2 × 10− 5 mbar by thermal evaporation technique with 450±20 nm thickness. The effects of annealed temperature (deposits, 423, 523, and 623) K for one hour on the structure, morphology, and optical properties of Copper Zinc Sulfide (CZS) films were investigated. The structural properties of Cu0.75Zn0.25S films were examined using the X-ray diffraction (XRD) technique as a function of annealed temperatures. XRD presented the Cu0.75Zn0.25S films as polycrystalline in the environment by a mixed hexagonal structure of CuS-ZnS, preferred orientation along the (201) plane, and crystallite size varying from 8.41-23.28 nm wit

Automatic Number Plate Recognition (ANPR) technology has offered a good solution tool for automating toll collection system processing and contributing solutions to complications such as traffic congestion, environmental problems, and operational inefficiencies. The investigation focuses on improving and organizing an ANPR-based system to allow smooth toll charging and letting cars pass through toll gates without pausing.
