We found a new value of supermassive black hole (SMBH) mass in the middle of type 1 Seyfert, NGC 4151 galaxy. In this Study, the image of NGC 4151 galaxy was deprojected to face-on, using spiral galaxy of face-on, and applied IRAF to calculate the ellipticity and position angle of major-axis. A two-dimensional (2D) Fast Fourier Transform (FFT) applied to the deprojected image to calculate the spiral arm of NGC 4151 galaxy, and, in that way, find a central mass AGN 4151 galaxy. We compared our results of the mass of SMBH in in the center of NGC 4151 galaxy with the mass of SMBH calculated using different methods ((direct method: stellar dynamics, gas dynamics, reverberation mapping), and indirect method: MBH-σ*, MBH-Vrot, MBH-n, MBH-Lbulge, and MBH-P correlations). We concluded that the results of mass for these methods are in agreement with the estimated ones, i.e. using direct methods.

It is predicted that Kurdish people, especially in Garmian District, face more mental health issues due to war, displacement and numerous political conflicts. On the other hand, different studies showed that mental health of university students decreases during their educational years. So, this study aimed to investigate the mental health of students in University of Garmian, using the Kurdish General Health Questionnaire (K-GHQ). In this cross-sectional study sample consists of 156 students selected by multistage cluster sampling among the students of five colleges from the University of Garmian. Furthermore, data were collected using Kurdish version of GHQ and demographic questionnaire. First, the GHQ successfully translated into Kurdish and back translated into English by independent professional bilingual translators. After preparing the finalized Kurdish GHQ, data were collected from May 2018 to February 2019. The investigation of reliability and validity of K-GHQ showed that this version is a valid and reliable tool for evaluation of mental health in university students. The average of mental health scores showed that only 3.25% of students were at normal mental health status and more than 96.75% of the participants were at risk. Of these, 37.6% suffered from mild problems, 51.9% had moderate, and 7.14% had severe problems. The higher scores were due to anxiety/insomnia (14.24) and social dysfunction (11.86). However, no differences were observed between the genders, but there were significant differences in global score and three sub-scales scores between freshmen and students of other grades. Because of the high prevalence of mental health problems in students of University of Garmian, effective interventions like CBT, MBSR and TFT are needed to reduce the effect of stressors and improve their mental health status.

Toll-like receptors (TLRs), encoded by innate immune genes, functions to detect microbial ligands. Studies found that polymorphisms in TLR genes among populations are associated with diseases. Among the classes of TLRs, TLR-4 is important for exploring bacterial lipopolysaccharide. TLR-4 Thre399Ile is one of the most important non-synonymous variant which varies among different background populations. Kurds, an ethnic population descended mainly from indigenous inhabitants of Zagros mountain survived for millennia, with nearly 40 million populations, are distributed in Iraq, Turkey, Iran and Syria. There are no studies on genetic variations of TLR4 in this population, particularly in Iraqi Kurdistan. The aim of this study is to find the percentage frequency of TLR4 Thr399Ile variant in Kurdish populations in Iraq, particularly in Sulaymaniyah province. The percentage of single nucleotide polymorphisms (SNPs) of the TLR4 gene was determined by polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP). The results showed that the heterozygous variant of TLR4 Thr399Ile is 7.1% (n=85) in Sulaymaniyah populations. However, no homozygous mutant variant was found; this suggests that it is either absent or seldom among Kurds in the region. This study emphasises the perceptiveness of the TLR SNP in Sulaymaniyah populations that recommends future study for linking this genetic variation with both infectious and immunological diseases, in addition to historical, anthropological and archaeological studies.

Wound healing is physiological process, passing through three main overlapping phases, including inflammatory, proliferative, and remodeling phase to repair the damaged tissue. Some vital process in wound healing, including inflammatory cell infiltration, angiogenesis and collagen tissue formation, seems to be disrupted in diabetes, which is a metabolic disorder. The aims of this study were to investigate the effect of different concentrations of hydroalcoholic extract of Teucrium polium, which is a medicinal plant, on the process of wound healing in diabetic rats. Diabetes were induced in twenty adult Albino-rats using a single intraperitoneal injection of streptozocin. Five wounds were created on the back of each rat, and treated as control (untreated), vasaline-treated, and 5%, 10% or 15% Teucrium polium extract-treated. The results showed that Teucrium polium extract stimulated wound healing by enhancing the rate of wound retraction, angiogenesis, fibroblast proliferation, collagen deposition, and maturation. Although there was a reduction in the level of granulation tissue thickness deposition within the wound. The rate of the epithelial regeneration was improved, and the thickness of the regenerated epithelium was reduced. Overall, there was a promising impact of the extract on the process of wound healing through improving different phases of the process.

Smoking is one of the modifiable cardiovascular risk factors which can alter normal levels of blood lipid parameters, in addition to body mass index (BMI) and waist circumference (WC). This study evaluates the effect of smoking on serum lipid profile and its correlation with some obesity indexes including WC and BMI among young males. The study Targets different groups that consist of 46 smoker group and 20 non-smokersas control group that are age and weight matched. Fasting serum level of lipid profile was estimated in both groups. The results showed significant elevation only in fasting blood triglyceride TG and very low density lipoprotein VLDL-C among smokers in compare with non-smokers group. In addition, it shows non-significant change in the levels of fasting blood total cholesterol TC, HDL-C and LDL-C as compared with the concentrations in the non-smoker group. However, a significant positive correlation is found between TG with each of BMI, WC and Duration of smoking (yrs.), there was a significant positive correlation between TC with each of BMI and WC, This study concludes that the mostly altered lipid parameters in the smokers is TG Whereas the less one is TC that could be worsened by increasing in some obesity indexes.
