The present study was performed to evaluate the level of some risk factors (biochemical and immunological) in hypothyroid Iraqi patients considering the different thyroid functional states (hypothyroidism and subclinical hypothyroidism).The study includes 82 patients clinically diagnosed with hypothyroidism. Three study groups have been investigated: (47 clinical hypothyroid patients, 12 subclinical hypothyroid patients 23 healthy individuals) of different ages. This study, show that the proportion of females (83.3 %), (87.2%) in subclinical and clinical hypothyroidisim respectively higher than the proportion of males (16.7%),(12.8%) in subclinical and clinical hypothyrodism respectively of the total patients.The majority of subclinical hypothyroidism patients were found to be obese (61.7%) followed by normal weight class (21.3%).While in the case of clinical hypothyroidism the majority of patients are from the class of normal weight (66.7%) followed by over weight class (33.3%). The statistical study showed no significant differences in the TSH level between the weight categories among each of the studied groups, but the weight between 25-29.9 kg/m2 showed a highly significant increase and a significant increase in the level of TSH in the clinical and subclinical cases in comparison to its level in the healthy group. No significant differences were found in the level of HDL cholesterol (Good cholesterol) and triglyceride among the patient,s groups in comparison with its level of the control LDL cholesterol (Bad cholesterol) level increased in the subclinical and the clinical hypothyroid patients in comparison with its level in the healthy group, statistical analysis showed no significant differences in LDL–C. level between the subclinical and healthy groups. In contrast, there is a significant difference in LDL–C. level between clinical and healthy groups.The same relationships were noticed in the total chol. level and atherogenic agent.(nonsignificant increase in the subclinical hypothyroid patients and a significant increase in the clinical cases in comparison with its level in the healthy persons). No significant differences were found in the level of IL12 and IL-33 between the studied groups. Serum IL-33 level was lower in subclinical hypothyroid patients in comparison to its level in the other groups. In conclusion, as long as cholesterol and TSH continue high, the patients become more susceptible to coronary heart disease as proved through calculating atherogenic agent in each group. According to the positive relationship between thyroid hormones and IL-12, the latter may act as immunomodulating agents. The decrease of IL-33 in subclinical hypothyroid group suggests humeral immunological failure which may need more studies and evaluating for the other related cytokines.
The main goal of this paper is to introduce the higher derivatives multivalent harmonic function class, which is defined by the general linear operator. As a result, geometric properties such as coefficient estimation, convex combination, extreme point, distortion theorem and convolution property are obtained. Finally, we show that this class is invariant under the Bernandi-Libera-Livingston integral for harmonic functions.

Background: The purpose of this study was to evaluate the effect of in vitro long-term simulation of oral conditions on the bond strength of PEEK CAD/CAM lingual retainers.
Material and methods: The sample consisted of 12 PEEK CAD/CAM retainers each composed of 2 centrally perforated 3x4mm pads joined by a connector. They were treated by 98% sulfuric acid for 1 minute and then conditioned with Single Bond Universal and bonded to the lingual surface of premolar teeth by 3M Transbond TM System. Half of the retainers were artificially aged using a 30-day water storage and 5000 thermocycling protocol before bond strength testing to compare with the non-aged specimens.
Results: The artificially aged retainers showed a marginally

Copper oxide (CuO) nanoparticles were synthesized through the thermal decomposition of a copper(II) Schiff-base complex. The complex was formed by reacting cupric acetate with a Schiff base in a 2:1 metal-to-ligand ratio. The Schiff base itself was synthesized via the condensation of benzidine and 2-hydroxybenzaldehyde in the presence of glacial acetic acid. This newly synthesized symmetric Schiff base served as the ligand for the Cu(II) metal ion complex. The ligand and its complex were characterized using several spectroscopic methods, including FTIR, UV-vis, 1H-NMR, 13C-NMR, CHNS, and AAS, along with TGA, molar conductivity and magnetic susceptibility measurements. The CuO nanoparticles were produced by thermally decomposing the

The university course timetable problem (UCTP) is typically a combinatorial optimization problem. Manually achieving a useful timetable requires many days of effort, and the results are still unsatisfactory. unsatisfactory. Various states of art methods (heuristic, meta-heuristic) are used to satisfactorily solve UCTP. However, these approaches typically represent the instance-specific solutions. The hyper-heuristic framework adequately addresses this complex problem. This research proposed Particle Swarm Optimizer-based Hyper Heuristic (HH PSO) to solve UCTP efficiently. PSO is used as a higher-level method that selects low-level heuristics (LLH) sequence which further generates an optimal solution. The proposed a

In this research, CNRs have been synthesized using pyrolysis of plastic waste(pp) at 1000 ° C for one hour in a closed reactor made from stainless steel, using magnesium oxide (MgO) as a catalyst. The resultant carbon nano rods were purified and characterized using energy dispersive X-ray spectroscopy (EDX), X-ray powder diffraction (XRD). The surface characteristics of carbon rods were observed with the Field emission scanning electron microscopy (FESEM). The carbon was evenly spread and had the highest concentration from SEM-EDX characterization. The results of XRD and FESEM have shown that carbon Nano rods (CNRs) were present in Nano figures, synthesized at 1000 ° C and with pyrolysis temperature 400° C. One of t
