Background: Traumatic ulcerative granuloma with stromal eosinophilia is an impressive benign chronic ulcerative lesion of the oral mucosa with vague etiopathogenesis. 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. Materials and methods: Formalin fixed - paraffin embedded tissue blocks of twenty-one cases were cut and mounted on positively charged slides and stained by primary antibodies (CD30, CD68 and TGF-β1). A statistical analysis was performed between the immunohistochemical scores for markers with each other and with clinicopathological parameters (age, sex, size of ulcer, number of eosinophils and mitoses). Results: The age of the patients ranged from 20 to 72 years, with a higher female propensity. Immunohistochemical positive expression for CD30 (16 case) mainly involved round small lymphocytes, while all cases were positive for CD68 and TGF-β1. Statistically, there was no significant relation between the scores of CD30, CD68 and TGF-β1 with each other and with the aforementioned parameters, (P<0.05). The eosinophils count showed a significant positive correlation with age (P=0.008), size of ulcer (P=0.007) and mitoses (P=0.004). Conclusion: Traumatic ulcerative granuloma with stromal eosinophilia is a benign and reactive chronic oral ulcerative lesion rather than being CD30+ lymphoproliferative disorder; this conclusion is supported by heterogeneous, focal and nonspecific staining for CD30 and being typically infiltrated by CD68+ macrophages. Whereas, a high level of expression for TGF-β1 indicated that the aforementioned factor was not associated with the delayed healing of this lesion
Encasing glass fiber reinforced polymer (GFRP) beam with reinforced concrete (RC) improves stability, prevents buckling of the web, and enhances the fire resistance efficiency. This paper provides experimental and numerical investigations on the flexural performance of RC specimens composite with encased pultruded GFRP I-sections. The effect of using shear studs to improve the composite interaction between the GFRP beam and concrete was explored. Three specimens were tested under three-point loading. The deformations, strains in the GFRP beams, and slippages between the GFRP beams and concrete were recorded. The embedded GFRP beam enhanced the peak loads by 65% and 51% for the composite specimens with and without shear connectors,

Show MoreIntroduction: Trichophyton indotineae has emerged globally as a highly contagious, terbinafine-resistant dermatophyte causing treatment-refractory superficial mycoses, posing a significant public health threat.This study evaluated the epidemiology of dermatophytosis in Babylon Province, Iraq, and performed molecular identification and phylogenetic analysis of local clinical isolates. Methods: Clinical specimens from 258 patients aged 1 to 71 years were analyzed. Following phenotypic characterization, genomic DNA was extracted from three representative isolates. Polymerase chain reaction amplified the internal transcribed spacer region, followed by DNA sequencing and neighbor-joining phylogenetic analysis. Results: Tinea corporis was
... Show MoreGlass fiber–reinforced polymer (GFRP) reinforcement provides an effective alternative to conventional steel in concrete structures due to its corrosion resistance. Nevertheless, the lower elastic modulus of GFRP necessitates careful consideration of serviceability behavior in GFRP-reinforced concrete members. This study presents a numerical sectional analysis model for predicting the flexural response and ultimate capacity of hybrid reinforced concrete beams incorporating embedded GFRP profiles in combination with either mild steel or GFRP reinforcement bars under monotonic static loading. The proposed model employs realistic nonlinear stress–strain relationships for concrete and steel, together with secant moduli of elasticity
... Show MoreThe posterior regions of the jaws usually represent a significant risk for implant surgery. A non-valid assessment of the available bone height may lead to either perforation of the maxillary sinus floor or encroachment of the inferior alveolar nerve and consequently to implant failure. This study aimed to evaluate the reliability of surgeon’s decision in appraising the appropriate implant length, in respect to vital anatomical structures, using panoramic radiographs.
Only implants that are inserted in relation to the maxillary sinus (MS) or the mandibular canal (MC) were enrolled (firs
The aim of the present study is to evaluate the change in the levels of glucagon, GLP-1 and GPCR in diabetic patient's and diabetic with dyslipidemia as metabolic syndrome. The study included 75 male aged ranged (30-50) years and with BMI (25-29) kg/m2 which divided into three groups as follows: group one (G1): consist of 25 subjects as healthy control group. Group two (G2): consist of 25 patient's with diabetes mellitus and group three (G3): consist of 25 patient's with diabetic and dyslipidemia as metabolic syndrome. Serum was used in determination of FBG, lipid profile, insulin, glucagon, GLP-1 and GPCR. Whole blood was determination of HbA1c. The results revealed significant elevation in FBG and HbA1c in G2 and G3 comparing to G1. While

Show MoreBackground: Dental implants provide a unique treatment modality for the replacement of lost dentition .This is accomplished by the insertion of relatively inert material (a biomaterial) into the soft and hard tissue of the jaws, there by providing support and retention for dental prostheses. Low level laser therapy (LLLT) is an effective tool used to prompt bone repair and modeling post surgery; this has referred to the biostimulation effect of LLLT. The aims of this study were to evaluate the immmunohistochemical expression of vascular endothelial growth factor (VEGF) and transforming growth factor -beta (TGF-β) in experimental and control groups with mechanical test. Materials and Methods: Thirty two adult New Zealand white rabbits use

This research not only reviews the problems, but it illustrates them in a philosophical way, basis of the data of modernity, this mean it is a process of connecting between the absence of the modernity values and the failure of development in underdeveloped countries. The Search follows the descriptive approach to get to the goal of search by four main axes. The first axis includes clarifying modernity and its principles, the second axis includes clarifying the economic development , the third axis includes the features of the mod
