The β-thalassemias are a group of recessively inherited genetic disorders that cause varying amounts of hemoglobin production. The study's aim was to look at hepcidin, ferretin, iron, PCV, Hb, ALT, AST, and albumin levels. Serum hepcidin, ferretin, iron, PCV, Hb, ALT, AST, and albumin levels were determined in 55 patients with beta-thalassemia and 55 healthy individuals. The results demonstrated a substantial rise in serum concentrations of ferretin, iron, ALT and AST in the beta-thalassemia group as compared to the control group(p<0.001). There was also a significant decrease in the concentrations in the serum of hepcidin, packed cell volume, hemoglobin and albumin (p<0.001).

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.

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.

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.

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.
血色沉着病是一种常见的遗传性疾病，会导致体内铁过量积聚，达到危险水平。遗传性血色病又称 HFE 相关性血色病，是由 HFE 基因的变化引起的。调查 HFE 基因的基因突变是探索这种疾病发病率的一种方法。本研究旨在确定巴士拉儿童专科医院（Basra Specialized Hospital for Children）和巴士拉AL-sadder教学医院（AL-sadder Teaching Hospital）患者的血色素沉着病HFE基因突变（C282Y和H63D）与儿童急性淋巴细胞白血病之间的关联。使用 QIAamp DNA 和血液迷你试剂盒分离和鉴定人类基因组 DNA，并使用 DNA 杂交法检测 HFE 基因突变。在这项研究中，发现患者和对照组均不存在 C282Y 突变。然而，基于 DNA 杂交实验的检测结果显示，H63D（同基因、杂合子）突变的检测水平较低；仅有 12.5%的患者检出了这种突变。对照组中有 10%的患者存在 H63D（仅同基因）突变。患者与对照组之间的关联被认为具有统计学意义。HFE 基因突变（C282Y 和 H63D）起源于儿童时期的急性淋巴细胞白血病，因此，本研究建议进行补充调查，以更多的患者病例更详细地说明这一病例，并发现这些突变背后隐藏的病原体。

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 saturable absorbent material on the characteristics of a single laser pulse results from the passive Q-switching method, or two pulses. The first pulse is resulted from the passive Q-switching method and the other is resulted from Stokes pulse generated by the laser ray reaction with the Raman medium in the optical system. This study simulated this effect on the characteristics of 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).

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.

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.

Multidrug resistance is a widespread issue that plays an important role in disease outcome. This study was designed to isolate Klebsiella pneumonia in different clinical specimens and detected their Antibiotic resistance profile. A total of 319 samples were collected from various clinical specimens for both genders and different ages. The samples were streaked on the blood and MacConkey agars. The bacterial growth identified using biochemical tests and Vitek®2 systems to confirm it. Also, the Vitek®2 system was used to detect the antibiotic sensitivity. Out of 319 clinical samples, K. pneumonia was identified in 67 (21%) cases. The highest isolation rate was in urine 25(37.3%), followed by sputum 13(19.4%), and the least isolation was in CSF with one isolate (1.5%). The results revealed that K. pneumonia isolates were multi-drug resistant pathogens (MDR) with high resistance to Ampicillin (97%) and 85% for piperacillin. The PCR results revealed blaVIM- genes frequency was 20 (30%). K. pneumonia is one of the bacteria that cause urinary tract infections, and it is a widespread multidrug-resistant pathogen, and blaVIM- producing K. pneumoniae are found in clinical samples at Thi-Qar hospitals. Therefore, monitoring the administration of antibiotics and their rational use is necessary to reduce antimicrobial resistance and treatment failure.
