— The effect of the saturable absorbent material on the characteristics of Passive Q-Switching and Stokes with Anti-Stokes Pulses Generated in Laser System of Nd:YVO4 has been investigated.. The three pulses (passive Q-switching pulse, Stokes pulse, and anti-Stokes pulse) simultaneously generated from one optical system. The optical system consists of Nd: YVO4, PbWO4, and Cr + 4: YAG as an effective medium, Raman medium and saturable absorbent material, respectively. The modeling of the rate equations was used, and the Rung-Kutta-Fehelberg numerical method was used to solve the rate equations. The results show increased power of the pulses generated, requiring an increased length of the saturable absorber material used in the system. The results showed that at the shortest length used for the saturated absorbent material, the pulse duration and energy of the three generated pulses were PQS pulse (16.44ns, 1.39mJ), Stokes pulse (12.59ns, 1.148mJ) and anti-Stokes pulse (13.53ns, 1.59mJ), while at the longest length of the saturated absorbent material, the pulse duration and energy were PQS pulse (14.68ns, 1.50mJ), the Stokes pulse (11.41ns, 1.36mJ) and the anti-Stokes pulse (12.38ns, 1.86mJ).

Hemochromatosis is a prevalent hereditary disorder that causes excess iron to build up in the body to dangerous levels. Hereditary hemochromatosis, also known as HFE-related hemochromatosis is carried on by changes in the HFE gene. Investigating the gene mutations of the HFE gene is a way to explore the prevalence of this disease. This study aims to determine the association between hemochromatosis HFE gene mutations (C282Y and H63D) and childhood acute lymphoblastic leukaemia in patients at Basra Specialized Hospital for Children and AL-sadder Teaching Hospital in the Basra governance. QIAamp DNA and Blood Mini Kit were used to isolate and identify Human genomic DNA and detect mutations in the HFE gene using the DNA hybridization method. In this study, the absence of the C282Y mutations in both patients and the control group was identified. However, testing DNA-based hybridization experiments revealed low detection levels of the H63D (homozygous, heterozygous) mutations; in only 12.5% of patients. The H63D (only homozygous) mutations were present in 10% of the control group. The association between patients and the control group is considered statistically significant. The HFE gene mutations (C282Y and H63D), originate in acute lymphoblastic leukaemia in childhood, thus, this study recommends complementary investigations to illustrate this case in more detail with more cases of patients and discover the hidden agents underlying these mutations.

Patients from the Specialized Heart Center in Thi-Qar Governorate with various diseases. A number of fungal species, including Candida tropicalis, were isolated by two samples from this isolate. Yeasts were purified and their DNA was extracted and then the DNA was transferred for the purpose of sending it to the Korean company in order to identify genetic mutations. For these species, a number of important genetic mutations were identified and recorded in the Gen Bank, as these isolated species contained genetic mutations that were compared with species isolated in other countries of the world that were officially registered in the Gen Bank. These fungi are considered the most important types of yeasts. They belong to the genus Candida and create a range of health problems for most people due to the fungal toxins they carry or the significant lung pathologies they cause. They can also be lethal or cause a number of serious ailments in most individuals.

The main purpose of this work is studying the linear Susceptibility in the hybrid nanostructure that composed of a dual quantum dot (DQD) and metal nanoparticle (MNP) hybrid system under a standing-wave field. In our model, we used density matrix equations by taking into our account the interaction between excitons and surface plasmons. The proposed DQD is composed of two QDs. Each QD contains an InAs QD with a disk shape. The interaction between the QD and the wetting layer (WL) is taken into consideration. The application of the standing wave field on DQD-MNP hybrid system was modeled and examined. The susceptibility of thehybridDQD-MNPsystem reduced by the pump field under a standing-wave field. The high susceptibility obtained with a wide MNP radius. An interesting result was shown in the inversion of the grating period with the tunneling component in the conduction band. The smaller size of DQD gave us high susceptibility due to the quantization effect.

The effect of the input pulse (chirped pulse) on the generation of soliton wave and optical frequency comb in microresonators was studied. The problem was solved numerically using the Lugiato-Lefever equation and the Fourier method by MATLAB program. The effect of Gaussian and ultra-Gaussian pulses, as well as chirped pulses, on the generation of the soliton wave and the frequency comb was also studied. Our study demonstrated that the generation of the soliton and the frequency comb depends on the shape of the pulse intensity distribution. Moreover, the mobility of the soliton and comb changes depending on the shape of the pulse. In addition, the results showed us that the soliton and frequency comb generated in microresonators are strongly affected by the power of the incoming pulse and the radius of the microresonator.

An uncommon autosomal recessive condition called DREAM-PL syndrome is typified by dysmorphic facial features, renal agenesis, male ambiguous genitalia, microcephaly, polydactyly, and lissencephaly. The CTU2 gene, which is in charge of tRNA post-transcriptional modification, is mutated in the syndrome. This alteration is necessary for the correct translation of genes, and its disruption can result in several aberrant embryonic processes. The severity of DREAM-PL syndrome can vary from moderate to severe, and the clinical characteristics can be diverse. While some patients may exhibit only some of the distinguishing features, others may have all of them. The most common characteristics include ambiguous genitalia, dysmorphic facies, and microcephaly. Diagnosis of DREAM-PL syndrome is typically based on clinical signs and confirmed through genetic testing, which can identify mutations in the CTU2 gene. Material and methodology: In the case being referred to as a study, a 37-week-old male neonate was delivered by lower segment cesarean section. The baby's birth weight was 2.760 Kg, and a heterozygous CMP mutation of the CTU2 gene was confirmed through whole-exome sequencing (WES). Unfortunately, there is currently no known cure for DREAM-PL syndrome. Result: Treatment focuses on managing the symptoms and providing supportive care. In some cases, surgical correction of birth defects may be beneficial.

In This study, we modified the Anderson-Newns model for atomic chemisorption to be suitable for the chemisorption of a spherical semiconducting quantum-dot on a monolayer pure perfect graphene.
A mathematical expression was used to calculate the occupation numbers for the two levels of the quantum-dot as a function of the normal distance and the external electric field. Appropriate formulas for other chemisorption functions were used by taking into our account the effect of image shift, and a formula for hybridization energy as a function of distance only. The quantum-dot was considered a spherical shape, chooses the type of on-top adsorption on the graphene layer, also taken a fixed value for the correlation energy U to be spin independent and not dependent on distance.
At room temperature T=300 K, the occupation numbers and their corresponding energy levels were calculated by stabilizing all the parameters α,V ̥,〖 U,d̥ ,ε_dot〗_ and varying the strength of electric field individually by both positive and negative directions. The contribution of the negative electric field was more effective on quantum-dot chemisorbed on graphene

Urinary tract infections (UTIs) in women are one of the most common diseases affecting at different ages of the life. This study was aimed to investigate the uropathogenes in women with UTI and to test their antibiotic susceptibility pattern. A total of 150 urine samples were collected from patients women and healthy in Thi-Qar Province, southern Iraq, between December 2022 and March 2023.Urine samples were collected from each participant women and cultured on media, then identified by different laboratory methods such as characteristic of colony on culture media, Gram stain, biochemical tests and morphologic chromatic properties on Hi UTI chromogenic agar and confirmed by API 20E system. The majority of females (44%) were the age groups 25 to 34 years followed by the (34%) patients were age group from 15 to 24 years. Antibiotic susceptibility testing for bacteria species was performed using the Kirby,Bauer disc, diffusion technique. Out of 136 different isolates with noticeable growth were found in the urine sample after microbiological cultures were performed, bacteria species was represented (63.24%) more than Candida species which was (36.76%). The most frequent bacterium was Staphylococcus species (40.69%) followed by Escherichia coli (18.60%). These bacterial exhibited extremely resistance to antibiotics. Gram positive isolates showed the highest resistant against Amoxicillin-clavulanate (100%), Ampicillin (100%), Oxacillin (100%), and Trimethoprim (91.66%), on the other hand Gram negative bacteria also showed the highest resistance against Amoxicillin-clavulanate (100%), Piperacillin (100 %), and both Ceftazidime and Nitrofurantoin (86.36 %). Other antibiotics showed different results by different bacterial species.

— The COVID-19 pandemic has led to a search for effective pharmaceuticals and vitamins to combat the virus. These therapies have antiviral capabilities and can affect both gram-negative and gram-positive bacteria. This study aims to assess the effectiveness of various medications and nutrients in treating bacterial infections linked to COVID-19. In vitro, tests will be conducted to evaluate these therapies' antibacterial efficacy against both gram-negative and gram-positive bacteria.
In the current study, we test a group of antibiotics commonly used in treating Coronavirus on different types of Gram-positive and Gram-negative bacteria. They found that Azithromycin was highly effective against both positive and negative bacteria, but its effectiveness decreased when combined with vitamin D. Levofloxacin was the most effective antibiotic, and its efficacy was not affected by the addition of zinc or vitamin D. Acyclovir had a slight effect on bacteria when used alone, but its efficacy improved with zinc. Zinc and Vitamin D had a high degree of effectiveness, but Vitamin D had relatively low efficacy, except against one type of bacteria.
The study aims to evaluate the effectiveness of drugs and vitamins against bacterial infections in COVID-19 patients. The results will provide a better understanding of the potential advantages of these medications in controlling bacterial infections.

A decorated ferrimagnetic mixed triangular system was studied using the molecular mean-field approximation. The outcomes of the investigation were examined using the Blume-Capel Ising model. The study paper investigates the influence of crystal and external magnetic fields on ferrimagnetic devices decorated with mixed spin-2 and spin-7/2 of a triangular lattice. It is noteworthy that spin-2 ions are located at the nodal points, whereas six additional spin-7/2 ions surround the proposed lattice. Altering the exchange interactions through the specific crystal and external magnetic fields induces superparamagnetic behaviours. New characteristics reveal that mixed spin triangular decorated ferrimagnets exhibit superparamagnetic behaviour at DA∕|J2|=-2.5, with J1 = -0.5 and J2 = -1.0 in the range (15 ≤ KBT /|J2| ≤ 18). It is important to note that the total magnetization changes with the external magnetic field and affects the superparamagnetism phenomenon of a decorated mixed spin ferrimagnet when DA/|J2| = 8, and DB/|J2|=-11, J1 = -0.5 and J2 = 1, for KBT/|J2| = 2, 2.5, 3, 3.5, and 4 Ko respectively

Sequencing reactions showed the accurate identity of the investigated samples and revealed that all investigated samples were homologous to Dipodascus capitatus (GenBank acc. no. OW983902.1). The presence of one nucleic acid variant compared with the referring sequences of the D. capitatussequences was demonstrated. The identified variant was represented by a nucleic acid substitution (359A>T) detected in the S5 sample. Meanwhile, the rest of the samples showed a complete homology with the corresponding sequences and did not exhibit any detectable nucleic acid variations in comparison with the D. capitatus reference sequences. It was inferred from the tree that the detected nucleic acid substitutions showed a slight effect of the observed variations on the altering evolutionary positioning of the investigated S5 sample in comparison with the other wild-type sequences. This was due to the positioning of the altered samples in the other positions compared with the wild-type counterparts. It was inferred from the tree that our investigated D. capitatus samples were suited in the immediate vicinity to various strains deposited from various multi-national positions. Furthermore, neighbor phylogenetic distances in this tree indicated a distinct biological diversity of D. capitatus sequences.

In this paper, we present a novel method for building a plasmonic photonic crystal fiber (PCF) sensor with simplified features to identify unknown analytes. Using the special parameters of plasmonic PCFs, the suggested sensor increases the sensitivity and specificity of target analyte detection. We provide a streamlined design approach that reduces manufacturing complexity without sacrificing reliable performance, opening up the sensor to new useful applications. We show the optimal structure parameters for optimizing sensitivity using the finite element method in the COMSOL environment. The suggested configuration attained strong spectral sensitivity throughout an extensive range of the analyte's refractive indices. Furthermore, a perfect linear connection was established between the analyte's refractive index and the resonant wavelength, qualifying the sensor for usage across the whole range of the analyte's refractive indices

The analysis by High-performance liquid chromatography (HPLC) revealed that the saponin extracts contain a significant component called (Hederagenin glycoside). The wavelengths and electronic transitions of the active groups of the saponin extract were also determined using the UV-Vis Spectra. The optimal result was obtained by utilizing the Gemini C18 (5 µm) stationary phase manufactured by Phenomenex. They determine the optimal chromatographic conditions for enhancing LC/MS analysis by evaluating several mobile phases on a reversed-phase C18 column. Illustrates the anticipated patterns of fragmentation observed in the mass spectra of substances. The Antifungal activity against Aspergillus flavus, Aspergillus Niger, and Aspergillus Alternaria was determined. The inhibitory effect in vitro was defined to appear, triterpenoid saponins extract showed maximum growth activity inhibitory of fungi against pathogens like Aspergillus Alternaria and Aspergillus Niger (2 cm), at the concentration (100 ppm) and the minimum growth activity inhibitory was against Aspergillus Alternaria (5 cm) at a concentration (25 ppm) compare with control. The triterpenoid saponins extract its ability to grow activity inhibition of fungi type Aspergillus Alternaria, Aspergillus Niger. On the other hand, the percentage of hemolysis activity in human blood increases with a high concentration of triterpenoid Saponins extract.

Sustainability has evolved into a broad phrase that includes practically every aspect of life on the Earth, from local to global, and over different periods. Sustainable biological systems include healthy, long-lived forests and wetlands. This paper aimed to study and measure pollution indicators in the Al-Hai city center's air, soil, and water in Wasit province, located at Coordinates (32.1742 N° and 46.0433 E°). The data for Al-Hai city's ambient air pollutants (CO, NO, NO2, H2S, SO2, and CO2) that considered air pollution was recorded for the date (12-13/12/2021). The Maximum values for the concentration of carbon monoxide CO and sulfur dioxide SO2 were 1.019 ppm and 0.0321 ppm, respectively. The water and sediment samples were collected in December 2021, and all samples were analyzed in the laboratory. Heavy elements (Cd, Pb, As, and Hg) were measured in soil and water. The samples were collected and taken from two stations in the Gharraf River of Al-Hai city in Wasit province to investigate the potential for environmental damage caused by these components in this region. This study will be conducted at two stations (North and South of Al-Hai city center) beginning in December 2021. In the south station, all heavy elements showed exponential growth in water and sediment samples, but concentrations in the north station were low. The highest value recorded in this study was for the pb concentration in the soil samples taken from the main street, which was 31.9 ppm. The rates of air, water, and soil pollutants increase in the winter due to the increase in the amount of rain, which leads to the deposition of pollutants and an increase in the water level of the Gharraf River. Another reason for the presence of pollutants is the inability to manage wastewater

Abstract— Predatory heterotrophic protozoa known as free-living amoebae (FLA) are found in various environmental sources. They have been linked to deadly cases of encephalitis, blinding keratitis, and pneumonia in humans. This study was performed in Thi-Qar province, south of Iraq, to identify the opportunistic FLA and detect it using morphological characteristics in the culture and Polymers Chain Reaction (PCR) amplification targeting specific genes for each genus. One hundred and two (102) samples were collected between February and September 2020; these samples were collected from several environmental sources, soil, water (rivers, tap water, tank water, stagnant water, the marshes water ,and drops of water from the air conditioner units ) and animals wastes(lizard, birds ,and wild mice), and 27 clinical samples ( eye, skin, ear, and Cerebral Spinal Fluid) gathered from private laboratories in the province of Thi-Qar as well as the Al-Hussain, Bint AL-Huda, and Al-Hboobi teaching hospitals. All samples were grown in Non Nutrient agar medium (NN-agar medium), which was subsequently studied under a light microscope to identify the trophozoites and cysts of opportunistic amoebas from the following genera: Sappinia spp. (S. pedata, S. diploidea), Acanthamoeba spp. (A. triangularis, A. astronyxis, A. castellini, A. polyphaga), and Naegleria fowleri and Balamuthia mandrillaris, the study found 62 (60.78%) samples were positive for total opportunistic FLA, and 40(39.21%) samples were negative, the incidence of FLA in environmental samples was 76% and in clinical samples were18.51 %. Sappinia spp. was the most common amoeba in both environmental and clinical samples while Naegleria fowleri was less present. Among the 62 environmental and clinical isolates of common FLA that were positive microscopically, only 48(47.05%) of them were positive after polymerase chain reaction, the incidence of FLA in environmental samples was 58.66% and in clinical samples was 14.81%.

— Beta thalassemia (β-thalassemia) is the most severe kind of β-thalassemia hereditary disease that makes blood transfusion dependent. Patients with β-thalassemia disease experience many physiological abnormalities, including oxidative stress, iron overload, and aggregated β-globin proteins. These abnormalities may also lead to premature RBC mortality. In the present study, 100 patients with β-thalassemia major with an average age of 16.30 ± 6.67 years old and 30 healthy controls with an average age of 14.63 ± 4.17 years old were included in this study. The serum levels of urea, creatinine, serotonin, and cortisol were investigated in the patient and control groups. The results showed a marked increase in the urea levels among the patients compared to the control group (from 14.63 ± 6.05 mg/dl in the control group to 24.98 ± 11.35 mg/dl in patient group) with P <0.001, rendering this change highly statistically significant. While there was a noticeable increase in creatinine levels between patients and controls (from 0.387 ± 0.199 mg/dl in the control group to 0.466 ± 0.208 mg/dl in the patient group. Statistical analysis revealed this change with non-significance of P = 0.066. Furthermore, the obtained results indicated that the serum level of serotonin decreased in patient group (from 393.46 ± 192.42 ng/ml in control group to 385.63 ± 167.70 ng/ml in patient group) with P=0.884, while β-thalassemia major subjects showed a significantly higher level of cortisol compared to the healthy control group (from 94.97 ± 67.56 ng/ml in control group to 304.37 ± 173.81 ng/ml in patient group) with P < 0.001. These findings showed an inverse correlation between the serum levels of serotonin, cortisol, and β-thalassemia major diseases.

Since deep eutectic solvents (DESs) are readily available, inexpensive, highly biodegradable, and easy to synthesize, they are gaining popularity as a green alternative to hazardous organic solvents and traditional ionic liquids (ILs). DES is a mixture of hydrogen bond donor (HBD) and acceptor (HBA) that is viscous and non-water soluble. There are two main penalty areas of DES fabrication. The first is to reduce its operation temperature to lower that of these components. The second is to produce a molten salt with a melting point lower than its components. Therefore, DESs are being utilized more and more in a range of analytical chemical applications. Different extraction techniques have been used for this kind of salt. In this review, production methods, and classification of DESs were discussed. The most physical properties of DESs were demonstrated, including melting point, viscosity, density, surface tension, phase changes in behavior, analyte solubility, instrumental compatibility, and toxicity. It also included the main advantages and disadvantages of DES production.

Since deep eutectic solvents (DESs) are readily available, inexpensive, highly biodegradable, and easy to synthesize, they are gaining popularity as a green alternative to hazardous organic solvents and traditional ionic liquids (ILs). DES is a mixture of hydrogen bond donor (HBD) and acceptor (HBA) that is viscous and non-water soluble. There are two main penalty areas of DES fabrication. The first is to reduce its operation temperature to lower that of these components. The second is to produce a molten salt with a melting point lower than its components.

Human skin is an island in constant interaction between diverse microorganisms (Archaea, fungi, bacteria, and protozoa), especially the inner elbow, armpit and buttocks, of which an imminent health danger is possible during injury or their sustained proliferation. Fat-soluble lauric acid-containing palm kernel oil, hardness-giving caustic soda and water solvent were essential ingredients used to produce toilet soap in this study, via a mechanized setup. Free caustic alkali (FCA), pH and moisture content (MC), as determined for additive (honey, clove, black seed) formulations A, B, C, D and E, which are respectively in the range of 0.006-0.02%, 7.10-9.97, and 7.33-15.33%, gave a soap of desired medicinal functionality. Formulation E physicochemical property compares favorably with other soaps, including Septol, Dettol, Premier, Joy, Sunlight, and Premier Cool found in Nigerian markets. It is found that the three additives introduced into the formulation in the ratio of 33, 50 and 17%, respectively, are responsible for its septic, antioxidant, antimicrobial and sanitizing properties. With this fit achieved, improvement, packaging and mass production of the produced toilet soap already having satisfactory foam stability, lathering, cleansing, fragrance, form and quality (according to SNI standard), is encouraged in this part of the world

Vitamin D is a type of molecule that can be dissolved in fats. It acts like a steroid hormone. There are two precursors of vitamin D, and both of them contain the steroid structure. One of them, 7-dehydrocholesterol, is in the lipids of animals , and the second one, ergosterol, is in plants Vitamin D is essential for the health of young children and their growth: it is responsible for calcium absorption and ensures bone and tooth strength. In addition, it plays a significant role in the functioning of the immune system and improves mental health and nervous development. Direct sunlight contains UVB rays needed for the skin to produce vitamin D. Children’s skin produces it quickly, but the body also uses its level quickly. Depending on the latitude, season, availability of clothes, and cream, which protects the skin from the sun, a person produces vitamin D in10 to 15 minutes to an hour. Areas that have limited sunlight or have children with darker skin or a medical condition may need more. The daily intake in a day may range from 400 to 1000 IU depending on the age and income level. However, Monitoring vitamin D status through blood tests and adjusting supplementation is essential to ensure adequate intake.

The study showed the repellent effect of three types of plant powders, Mentha, Myrtus and Ocimum basilica, against rice weevil Sitophilus oryzae (L.)

Urinary tract infections (UTIs) are considered the most prevalent infectious disorders. They can affect the entire urinary tract or specific a portion of it and are mostly brought on by bacteria that are found in the intestine. The present study included 82 pregnant women whom age ranged from 17 to 40 (mean ± SD: 27.44 ± 6.66) and divided to 13 in the first trimester, 9 in the second, and 60 in the third. Also, the study included 56 apparently healthy pregnant women as a control, with age (mean ± SD: 27.11 ± 5.59). Patients with UTIs had lower mean serum levels of IL-6 (12.08 ±16.35 pg/ml) compared to control group (42.19 ± 28.0 pg/ml). Also, the same patients showed had lower mean serum levels of IL-1β (6.91 ± 11.78 pg/ml) compared to control group (43.32 ± 34.62 pg/ml). The conclusions, UTIs continues to be one the most socio-health problems that need a lot of care diagnosis and treatment. Both IL-6 and IL-1β in UTIs pregnant women identification may contribute as Diagnostic marker tools for associated infections.

Thyroiditis is a general term that refers to thyroid gland inflammation. The present research was conducted to identify the role of thyroid peroxidase antibodies (TPO-Ab) in Thyroiditis patients and assaying the levels of thyroid function tests (TFT), which include levels of serum triiodothyronine hormone (T3), thyroxin hormone (T4), and thyroid stimulating hormone (TSH). A total of 86 serum samples (76 thyroiditis patients and 10 controls) from August 2023 to November 2023, at Al-Haboby Teaching Hospital and some private clinics in Thi-Qar Governorate were enrolled in the present study. The sandwich-ELISA technique assayed the levels of TPO-Ab, and the levels of (TFT) T3,T4, and TSH by using a competitive binding assay. Thyroiditis patients were divided into hypothyroidism and hyperthyroidism type with 47(61.84%) and 29(38.16%) patients, respectively (P≤0.05). Hypothyroidism and hyperthyroidism groups showed elevated mean serum levels of TPO-Ab (29.78%) and (20.68%) for members of each group separately, with a mean of (478.8) and (1070), respectively. While the mean of TPO-Ab in the control group was (319.5). The means of TFT in hypothyroidism group for T3,T4 and TSH were (0.9215), (5.402), and (22.86), respectively. The means of TFT in hyperthyroidism group for T3,T4 and TSH were (1.003), (7.409) and (0.3893), respectively, compared to the control. The mean of TFT for T3,T4 and TSH was (0.781), (7.374), and (1.603), respectively. As a demographic profile, Thyroiditis, with a high significant differences, tends to infect females (92.11%), middle-ages (21-40 years), housewives (81.58%), and urban residences (73.69%) (p≤ 0.001). The findings of the current study could illuminate the function of TPO-Ab and TFT as serological and diagnostic instruments in thyroiditis, and offer valuable contributions to the disease’s classification and evaluation.
