Nano-Clay Platelet Integration for Enhanced Bending Performance of Concrete Beams Resting on Elastic Foundation: An Analytical Investigation.

Acknowledging the growing impact of nanotechnologies across various fields, this engaging research paper focuses on harnessing the potential of nano-sized materials as enhancers for concretes. The paper emphasizes the strategic integration of these entities to comprehensively improve the strength and performance of concrete matrixes. To achieve this, an analytical study is conducted to investigate the static behavior of concrete beams infused with different types of clay nano-platelets (NC's), employing quasi-3D beam theory.

Investigation of the elastic constants of perfect and imperfect carbon nanocones using an adequate nonlinear atomic finite element model.

In order to investigate the elastic constants of pristine and imperfect carbon nanocones, the present work aims to develop an easy and efficient nonlinear atomic finite element model (AFEM) capable of capturing the torsional effect in addition to the bond stretching and bond angle bending interactions. These effects are considered the predominant atomistic interactions induced in carbon nanocones (CNCs). Hence, a new basic AFEM element containing nineteen atoms is developed and examined by studying the effect of the geometric parameters of CNCs on their Young's modulus and comparing the obtained results with the available literature.

The impact of nutrition and lifestyle on male fertility.

Background And Aims: Male unexplained infertility has long been suspected to result from environmental, lifestyle and nutritional factors. However, the literature on the subject is still scarce, and clinical studies providing robust evidence are even scarcer. In addition, some similar studies come to different conclusions.

[Separate entrance of the main pancreatic duct and of the common bile duct: is it synonymous with easy retrograde cholangiography using endoscopic approach?].

This study focused on endoscopic examination of a prominent papilla which showed two separate orifices revealing separate entrance of the main pancreatic duct and of the common bile duct (A). This was the most rare anatomoendoscopic variation, accounting for only 10% of retrograde cholangiopancreatographies using endoscopic approach (ERCP). However, it facilitated selective biliary catheterization (SBC) in our patient, as one might have expected.

[High blood pressure during the autonomic crises in children in intensive care unit: Etiologic circumstances and modality therapeutic].

Unlabelled: The dysautonomic (DC) or neurovegetative crisis remains an imperfectly known entity; it associates in a paroxysmal manner a reaction of sympathetic hyperreactivity that can lead to the prognosis. Our objective is to specify the etiological circumstances (DC) and their modality of treatment in pediatric intensive care unit.

Materials-methods: Descriptive study on files of children admitted in the intensive care unit of 2010-2015 who presented a DC acquired during their hospitalization.

The Buried Bumper Syndrome: External Bumper Extraction after Radial Mini Incisions and Replacement through an Adjacent Tract.

Although considered as a safe method to provide long-term nutritional support, percutaneous endoscopic gastrostomy (PEG) may be complicated by a buried bumper syndrome (BBS), a life-threatening condition. Removal of the PEG tube with its buried bumper and reinsertion of a new PEG tube is often necessary. Since its description in 1988, less than 50 cases of BBS managed by external extraction of the buried bumper have been reported.

Pre-existing renal lesions revealed after renal trauma, Difficulties in diagnosis and accountability: About 14 cases.

Objective: Pre-existing renal lesions (PERL) may interfere with the patho-physiology of trauma, alter the radiographic imaging and influence the therapeutic approach. The aims of this study were to record the PERL found incidentally during blunt renal trauma, to specify the place for effective conservative management and to determin the estimated partial permanent disability (PPD).

Patients And Methods: The medical records of 14 patients with PERL and blunt renal trauma were reviewed.

Prevalence of erectile dysfunction in patients consulting urological clinics: multi-centric survey in the algerian west.

Aim: to make an inventory of the prevalence, the severity, the reasons for the patient's consultation and the therapeutic measures indicated by urologists for erectile dysfunction (ED) in the west of Algeria.

Methods: This survey was conducted among 4 urologists. All male patients, aged over 18 years, presenting to clinics during the study period of 2 months were included.

Impacted and Fractured Biliary Basket: A Second Basket Rescue Technique.

A 59-year-old woman was treated with ERCP, ES, and biliary plastic stent, for large and multiple common bile duct stones. During a second ERCP basket extraction was impacted with a round entrapped stone. The basket handle was cut off; a metal sheath of extraendoscopic lithotriptor was advanced over the basket.

Endoscopic retrieval of gastric trichobezoar after fragmentation with electrocautery using polypectomy snare and argon plasma coagulation in a pediatric patient.

Trichobezoars are rare, composed of hair and more common in female pediatric patients with psychiatric disorders. Open surgical extraction is the most common removal method. Only two endoscopic removals after fragmentation have been reported in the English literature.

Endoscopic stenting and clipping for anastomotic stricture and persistent tracheoesophageal fistula after surgical repair of esophageal atresia in an infant.

Anastomotic stricture (AS) and recurrent tracheoesophageal fistula (TEF) are two complications of surgical repair of esophageal atresia (EA). Therapeutic endoscopic modalities include stenting, tissue glue, and clipping for TEF and endoscopic balloon dilation bougienage and stenting for esophageal strictures. We report herein a two-month infant with both EA and TEF who benefited from a surgical repair for EA, at the third day of life.

Incidental diagnostic and treatment of a suppurative appendicitis at colonoscopy.

WE HEREIN REPORT A PATIENT WITH ACUTE APPENDICITIS WHO WAS DIAGNOSED BY COLONOSCOPY: a 54-year-old woman with normal physical examination and laboratory results within normal limits. The case had shown an erythematous and edematous bulging polypoid lesion with purulent discharging from appendiceal orifice into the cecum. At colonoscopy, appendix appeared as an erythematous and edematous bulging polypoid lesion with purulent discharging from appendiceal orifice into the coecum.
