Benign prostate hyperplasia (BPH), non-cancerous enlargement of prostate, is the most prevalent disease entity in elderly men. BPH affects 40% of men after the age of 60year worldwide. BPH causes problems for patients with significant lower urinary tract obstructive symptoms, if not responding to medical therapy, surgical intervention is instituted. One method of the treatment of symptomatic BPH is laser prostatectomy. The understanding of tissue effects by laser radiation is very important for the safe clinical application of laser. Objective: study the 2100 nm Ho: YAG laser gross tissue effects in the prostate at different laser dose settings in an vitro model prostate tissue samples harvested from same specimen of open surgery prostatectomy. Materials and methods: Specimen of same open surgery prostatectomy was sectioned into six samples preserved in 4% formalin solution. Laser irradiations were performed in ambient air at room temperature. Samples exposed to varying laser dose parameters using pulsed Ho: YAG laser. The laser settings consisted of energy per pulse (0.3, 0.5 and 1 J), and pulse repetition rate (10 and 25 Hz) in single or double pulse mode. Pulse duration was 350 μs. Laser radiation was delivered using laser fibers with an optical core diameter of 550 μm. Main evaluation criteria of the Ho::YAG laser performance in prostate tissue was made by visual gross appearance of the effects of incision, cutting, vaporization, ablation and coagulation properties. Results: high laser dose setting revealed ablation, vaporization, incision, and cutting performance. Also there was clear evidence of coagulation zone. There was no clear appearance of carbonization. Sometimes minimum carbonization effect noticed. Ablation of prostate tissue was achieved by low dose setting. High and Low settings were responsible for coagulation effect. Conclusion: different dose parameters including energy per pulse, pulse repetition rate and in single or double pulse mode provide an effective way for ablation, vaporization, incision, cutting and coagulation effects in the prostate tissue.
Trimethoprim derivative Schiff bases are versatile ligands synthesized with carbonyl groups from the condensation of primary amines (amino acids). Because of their broad range of biological activity, these compounds are very important in the medical and pharmaceutical fields. Biological activities such as antibacterial, antifungal and antitumor activity are often seen. Transition metal complexes derived from biological activity Schiff base ligands have been commonly used
Batch reactive distillation was studied in packed bed column. Esterification of methanol with acetic acid to produce methyl acetate and water with homogenous sulfuric acid as a catalyst was considered. This system was chosen because the reaction is reversible and the boiling point of reactant and products are different.
The reaction was carried out with and without distillation column and shows that the reactive distillation is more efficient from the conventional process (reactor and then separation). The conversion of acetic acid and concentration of methyl acetate increase by (30.43% and 75.14%) respectively at the best condition (reflux ratio 2, feed mole ratio 2 and batch time 90 minute).

Vitiligo is an acquired idiopathic skin disorder characterized by depigmented macules due to loss of cutaneous melanocytes. A potential role of the immune dysfunction has been suggested in vitiligo, so to test this hypothesis, certain cytokines (IL-17A and TNF-?) and immunoglobulins (IgM, IgG, IgA and total IgE) were investigated in all participants. The study included: 60 patients with age range between (6-55) year; 30(11 males and 19 females) were untreated and 30(12 males and 18 females) were treated with Narrow Band Ultraviolet-B (NB-UVB) and 30 (14 males and 16 females) apparently healthy control. Serum was separated and cytokines (IL-17A and TNF-?) and total immunoglobulin E (IgE) were detected by using Enzyme Linked Immunosorbent Ass

Summary
The book (Fatah al-Rahman reveals what is ambiguous in the Qur’an), which is a book of verbal similarities that tries to touch the Qur’an expression, and the subtle differences between its expressions and expressions. It appeared when it appeared in many chapters, from which I chose to delete in monolithic letters such as Ba and Ta, and to heal and delete in non-monosymbols such as (that) and (may) and (no), so the search came to two chapters The first is for deleting the monolithic letters, and the second is for deleting non-monosyllabic letters, preceded by introductory discussions revolving around the linguistic and idiomatic definition of deletion, a brief translation of the

It also stopped at the methodological impact of value on defining the analytical linguistic unit and the value role in semantics through the prin
