Introduction: Cutaneous leishmaniasis is considered a parasitic contagion resulting from the flagellated parasite belonging to the genus of Leishmania. Also, cutaneous leishmaniasis is a zoonotic ailment transmitted through the bloodsucking sand-flies bite (belonging to the Phlebotomus genus). The disease's reservoirs included wild or semi-domesticated animals, in general rodents and dogs. Tissue inhibitor metalloproteinase-1 (TIMP-1) is one of the extracellular matrix proteins that have a role in vessel wall degeneration and aneurysm development. In addition, it belongs to the zinc-dependent endopeptidases family that are involved in the degradation of connective tissues proteins which are included in vascular integrity maintenance. The Genetic deviations in the TIMP-1 genes might impact their expression at the transcription level or the enzyme activity. Therefore, the present study aimed to detect the impact of TIMP-1 serum level and single nucleotide polymorphisms (SNPs) rs41454248 and rs1043428 among the cutaneous leishmaniasis patients’ group compared to the control group. Subjects: Seventy-five cutaneous leishmaniasis patients (39 males and 36 females) with the age mean 23.91 ± 13.14 years participated in this study, compared to the matched number, age, and gender of a healthy control group (75: 38 males and 37 females) with the age mean 22.84 ± 4.35 years. In the current study, the serum level of TIM-1 and rs41454248 and rs1043428 SNPs were studied among the cutaneous leishmaniasis patients’ group compared to the control group. Results: The findings of the TIMP-1 level referred to a significant decrease among the cutaneous leishmaniasis patients’ group compared to the healthy control group (26339.67 ± 900.79 vs. 33480.25 ± 1098.63). Such, the rs41454248 SNPs findings referred that the GG genotype and G allele were non-significantly increased frequency percentage in cutaneous leishmaniasis patients group compared to the healthy control group (29.33 vs. 18.67%, OR: 1.81, p = 0.180; 55.0 vs. 47.0%, OR: 1.38, p = 0.204 respectively). Also, the high OR value of GG genotype and G allele referred to this genotype and allele might be a risk factor for cutaneous leishmaniasis. Likewise, the findings of rs1043428 SNPs appeared that the CC genotype and C allele were significantly increased frequency percentage in cutaneous leishmaniasis patients' group compared to the control group (37.33 vs. 4.0%, OR: 14.30, p = 3.6 × 10−7; 57.0 vs. 21.33, OR: 4.82, p = 4.5 × 10−10). Also, the high OR value of CC genotype and C allele referred to this genotype and allele might be risk factors for cutaneous leishmaniasis. In addition, the CG genotype appeared a non-significant increased frequency percentage in the patients' group compared to the control group and the value of OR referred to might be a risk factor for cutaneous leishmaniasis (33.33 vs. 25.33, OR: 1.47, p = 0.370). In addition, the serum level of TIMP-1 with the rs41454248 was significantly decreased in GA and AA genotypes of the patients’ group compared to the control. While the level was non-significantly decreased in the GG genotype of the patients' group compared to the control group. Likewise, the level of TIMP-1 with the rs1043428 was non-significantly decreased in all genotypes (except TT genotype) of the patients' group compared to the control. Whereas, a significant decrease level was appeared in the TT genotype of the patients' group compared to the healthy control group. Conclusion: The current findings demonstrated a significant association between TIMP-1 serum level and genetic polymorphisms (rs1043428 and rs41454248) among cutaneous leishmaniasis patients.
The main problem established by a discovery of a thyroid nodule is to discriminate between a benign and malignant lesion. Differential diagnosis between follicular thyroid cancer (FTC) and benign follicular thyroid adenoma (FTA) is a great challenge for even an experienced pathologist and requires special effort. A developing number of some encouraging IHC markers for the differential diagnosis of thyroid lesions have emerged, including, Hector Battifora mesothelial (HBME-1) and galectin-3 (Gal-3). There was significant positive correlation between Galectin-3 and HBME-1 in follicular carcinoma and follicular variant of papillary carcinoma (r= 0.380, P= 0.041) and (r= 0.315, P=0.047) respectively. There was no significant correlation between

The structures of these derivatives were characterized from their melting points, infrared spectroscopy and elemental analysis. These derivatives were tested for inhibition of E-coli and were all found to be active
(Sb2S3)1-xSnx thin films with different concentrations (0, 0.05 and
0.15) and thicknesses (300,500 and 700nm) have been deposited by
single source vacuum thermal evaporation onto glass substrates at
ambient temperature to study the effect of tin content, thickness and

An inverse relationship between serum selenium levels and cervical intraepithelial neoplasia has been reported. cervical intraepithelial neoplasia is regarded as a potentially premalignant transformation of squamous cells of the cervix. Objectives: To evaluate the relationship between the serum level of selenium and cervical intraepithelial neoplasia. Methods: A case-control study was conducted at Baghdad Teaching Hospital and Iraqi National Cancer Research Center in the University of Baghdad during the period from July 2021 to July 2022.

It was supposed to represent an oral counterpart of primary cutaneous CD30+ lymphoproliferative disorder. Histopathologically, it is characterized by mixed inflammatory infiltrate predominated by histiocytes, lymphocytes and eosinophils along with presence of scattered large atypical mononuclear cells. It has worrisome clinical presentation. It may heal spontaneously, but in most occasions it persists and never heal unless removed surgically (incisional or excisional biopsy). A rare subset may show worrisome immunohistochemical features. Follow up is highly recommended. Mat
