Effect of docosahexaenoic acid as a chemopreventive agent on experimentally induced hamster buccal pouch carcinogenesis.

Purpose: The current study was directed to investigate the effectiveness of docosahexaenoic acid (DHA) as a chemopreventive agent on experimentally induced hamster buccal pouch (HBP) carcinogenesis.

Material And Methods: In this study we used 40 Syrian male hamsters, five weeks old, were divided into 4 groups (GI, GII, GIII, and GIV) of 10 animals in each as follows, GI: Topical application of liquid paraffin alone (thrice a week for 14 weeks), GII: Topical application of 7, 12 dimethyl benz[a]anthracene (DMBA) alone (0.5% in liquid paraffin, thrice a week for 14 weeks), GIII: Topical application of DMBA (0.

Roles of Proliferation and Angiogenesis in Locally Aggressive Biologic Behavior of Ameloblastoma versus Ameloblastic Fibroma.

(1) Background: The present study was carried out to evaluate the roles of proliferation and angiogenesis in locally aggressive biologic behavior of ameloblastoma versus ameloblastic fibroma; (2) Methods: 30 formalin-fixed paraffin embedded blocks (15 cases of ameloblastoma and 15 cases of ameloblastic fibroma) were used. To evaluate the proliferation, the tissue sections were stained with an AgNORs stain. CD105 was used as an immunohistochemical marker of angiogenesis.

Evaluation of two European risk models for predicting medication harm in an Australian patient cohort.

Purpose: To externally evaluate the performance of two European risk prediction models, for identifying patients at high-risk of medication harm, in an Australian hospital setting.

Methods: This was a secondary analysis of a pre-existing cohort study described in a recently published study by Falconer et al. (Br J Clin Pharmacol 87(3):1512-1524, 2021) describing the development of a predictive risk model for inpatient medication harm.

Evaluation of osteogenic potential of Cissus quadrangularis on mandibular alveolar ridge distraction.

Background: This randomized clinical trial was designed to evaluate osteogenic potential of Cissus quadrangularis in alveolar distraction to facilitate implant installation.

Material And Methods: Twenty patients with atrophic ridge were treated by alveolar distraction. After completing distractor activation, patients were randomly divided into two equal groups according to administered drug (placebo and Cissus quadrangularis group).

Three-dimensional ultrasonography and power Doppler for discrimination between benign and malignant endometrium in premenopausal women with abnormal uterine bleeding.

Background: Ultrasonography has been extensively used in women suspected of having a gynecological malignancy. The aim of this study is to evaluate the efficacy of 3D ultrasonography and power Doppler for discrimination between benign and malignant endometrium in premenopausal women with abnormal uterine bleeding.

Methods: This cross-sectional study included 78 premenopausal women with abnormal uterine bleeding scheduled for hysteroscopy and endometrial curettage.

Design and Synthesis of New Phthalazinone Derivatives Containing Benzyl Moiety with Anticipated Antitumor Activity.

The acetohydrazide derivative reacted with carbon electrophiles such as acid chlorides, acetylacetone, ethyl acetoacetate and aromatic aldehydes to give some interesting heterocyclic compounds. The hydrazide derivative reacted with acetophenone which in turn underwent Vielsmeier-Haack reaction. Also, the phthalazinethione has been synthesized and its behavior towards hydrazine hydrate, oxidizing agent and ethyl chloroacetate has been investigated.

Cost of acute stroke care for patients with atrial fibrillation compared with those in sinus rhythm.

Background: Atrial fibrillation (AF) is a major risk factor for stroke. Cost-effectiveness studies of anticoagulants for stroke prevention in AF rarely utilise AF-stroke-specific cost data in their analyses, as data are limited. Data that exist do not account for AF found on prolonged cardiac monitoring after stroke, further underestimating the clinical and economic burden of AF-stroke.

Congenital duodenal diverticula: a report of three cases and a review of the literature.

Most duodenal diverticula are acquired, extraluminal, and false, but the congenital variety is rare, whether it is intraluminal or extraluminal. We present two cases of extraluminal congenital duodenal diverticula and one of the intraluminal type, and we also review the literature. The clinical presentation involves rather nonspecific abdominal symptoms, and most of these diverticula are incidental findings on upper gastrointestinal series.

Inducing labor with oral prostaglandin E2 in Khartoum hospital.

Prostagland-n E2 (PGE2) was administered orally to 109 patients to induce labor. Sixty-five of these patients had an amniotomy prior to PGE2 administration. PGE2 was administered to the remaining.

Evaluation of a 4% gelatin solution in the treatment of canine haemorrhagic shock.

The effects of volume replacement with 4% gelatin containing 1% glycine at pH 5.8 and 6.4 on the changes in mean arterial blood pressure (MABP) and blood levels of glucose, lactate and urea following acute haemorrhage in dogs were studied.

Azoospermia in bilharziasis and the presence of sperm antibodies.

Sperm agglutinating, haemagglutinating and immobilizing antibodies were detected more frequently and in higher titres in the sera of azoospermic patients with urinogenital bilharziasis than in the sera of unaffected males. There is evidence that bilharziasis enhances the autoimmune response of the individual.
