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.

Background: the aim of this study was to assess the 2-year pulp survival of deep carious lesions in teeth excavated using a self-limiting protocol in a single-blind randomized controlled clinical trial. Methods: At baseline, 101 teeth with deep carious lesions in 86 patients were excavated randomly using self-limiting or control protocols. Standardized clinical examination and periapical radiographs of teeth were performed after 1- and 2-year follow-ups (REC 14/LO/0880). Results: During the 2-year period of the study, 24 teeth failed (16 and 8 at T12 and T24, respectively). Final analysis shows that 39/63 (61.9%) of teeth were deemed successful (16/33 (48.4%) and 23/30 (76.6%) in the control and experimental groups, respectively wit
... Show MoreAbstract: The utility of DNA sequencing in diagnosing and prognosis of diseases is vital for assessing the risk of genetic disorders, particularly for asymptomatic individuals with a genetic predisposition. Such diagnostic approaches are integral in guiding health and lifestyle decisions and preparing families with the necessary foreknowledge to anticipate potential genetic abnormalities. The present study explores implementing a define-by-run deep learning (DL) model optimized using the Tree-structured Parzen estimator algorithm to enhance the precision of genetic diagnostic tools. Unlike conventional models, the define-by-run model bolsters accuracy through dynamic adaptation to data during the learning process and iterative optimization
... Show MoreMost recognition system of human facial emotions are assessed solely on accuracy, even if other performance criteria are also thought to be important in the evaluation process such as sensitivity, precision, F-measure, and G-mean. Moreover, the most common problem that must be resolved in face emotion recognition systems is the feature extraction methods, which is comparable to traditional manual feature extraction methods. This traditional method is not able to extract features efficiently. In other words, there are redundant amount of features which are considered not significant, which affect the classification performance. In this work, a new system to recognize human facial emotions from images is proposed. The HOG (Histograms of Or
... Show MoreThe Electric Discharge (EDM) method is a novel thermoelectric manufacturing technique in which materials are removed by a controlled spark erosion process between two electrodes immersed in a dielectric medium. Because of the difficulties of EDM, determining the optimum cutting parameters to improve cutting performance is extremely tough. As a result, optimizing operating parameters is a critical processing step, particularly for non-traditional machining process like EDM. Adequate selection of processing parameters for the EDM process does not provide ideal conditions, due to the unpredictable processing time required for a given function. Models of Multiple Regression and Genetic Algorithm are considered as effective methods for determ

... Show MoreSoil pH is one of the main factors to consider before undertaking any agricultural operation. Methods for measuring soil pH vary, but all traditional methods require time, effort, and expertise. This study aimed to determine, predict, and map the spatial distribution of soil pH based on data taken from 50 sites using the Kriging geostatistical tool in ArcGIS as a first step. In the second step, the Support Vector Machines (SVM) machine learning algorithm was used to predict the soil pH based on the CIE-L*a*b values taken from the optical fiber sensor. The standard deviation of the soil pH values was 0.42, which indicates a more reliable measurement and the data distribution is normal.
