The aim of this work was to study the ability of using Hydrocabonoclastic native microbial and Spongiochloris sp microalgae in airlift bioreactors couples in order to restore hydrocarbons wastewater and develop the capacity of natural systems to reduce greenhouse effect through maximal control of CO2 gas emission in atmosphere. The kinetic parameters of CO2 gas fixation level and conversion it into biological material by microalgae as the biodegradation process effect in hydrocarbon have been evaluated. The result present that maximum specific growth rate μmax of Spongiochloris sp was (0...

BACKGROUND: Sigmoid volvulus (SV) is a common cause of large bowel obstruction worldwide. Presenting symptoms can be nonspecific and varied amongst the elderly population, making medical and surgical management challenging. This population is at markedly increase risk of complications and mortality with surgery under general anesthesia. In this case series, we describe 4 cases of sigmoid volvulus in octogenarians. GOALS: To demonstrate that sigmoid colectomy under local anesthesia, with or without intravenous conscious sedation, is feasible and can be done safely and with a low rate of converting to a general anesthetic...

Since chitin is closely associated with proteins, deproteinization is a crucial step in the process of extracting chitin. Thus, this research aimed to extract chitin from Portunus segnis and Penaeus kerathurus shells by means of crude digestive alkaline proteases from the viscera of P. segnis, regarding deproteinization step, as an alternative to chemical treatment. Casein zymography revealed that five caseinolytic proteases bands exist, suggesting the presence of at least five different major proteases. The optimum pH and temperature for protease activity was pH 8...

RATIONALE: The icosahedral carborane anion HCB11 H11(-1) is well known for its exceptional stability in solution and the solid state, but the gas-phase properties of this molecule have not previously been explored. METHODS: Electrospray ionization ion trap mass spectrometry, collisional activation, and isotopic labelling were used to examine the formation and reaction pathways of covalent and noncovalent carborane clusters. RESULTS: Covalent attachment of an amino group to the C-vertex of HCB11 H11(-1) dramatically alters its stability in the gas phase...

INTRODUCTION: Previous studies have demonstrated the predictive value of the neutrophil-to-lymphocyte ratio (NLR) in many cardiovascular disorders. The aim of this study was to assess whether NLR is associated with echocardiographic or electrocardiographic parameters, or with predicted five-year risk of sudden cardiac death (SCD), in patients with hypertrophic cardiomyopathy (HCM). METHODS: This prospective observational study included 74 controls and 97 HCM patients...

BACKGROUND: The aim of this study was to explore the effect of brain-derived neurotrophic factor (BDNF) polymorphism rs6265 (Val66Met) in both "natural" and treatment induced recovery of swallowing after dysphagic stroke. METHODS: Sixteen dysphagic stroke patients that completed a single-blind randomized sham controlled trial of pharyngeal electrical stimulation (PES) within 6 weeks of their stroke (N=38), were genotyped for the BDNF SNP Val66Met (rs6265) from saliva samples...

AIM: To evaluate the effect of varying cellulose casting ring liner length and its prewetting on the marginal adaptation and dimensional accuracy of full veneer metal castings. MATERIALS AND METHODS: The master die was milled in stainless steel to fabricate the wax pattern. Sixty wax patterns were fabricated with a uniform thickness of 1.5 mm at an occlusal surface and 1 mm axial surface, cervical width at 13.5 mm, and 10 mm cuspal height. The samples were divided into six groups (n = 10)...

OBJECTIVES: Co-administration of posaconazole (PSZ) and vincristine (VCR) in the treatment of patients with acute lymphoblastic leukemia increases the neurotoxicity of VCR. Our aim is to study the effect of increased lipoprotein levels on the pharmacokinetics of PSZ and VCR upon co-administration in rats. METHODS: Rats were assigned to three groups, normolipidemic (NL), intermediate hyperlipidemic (IHL), and extreme hyperlipidemic (HL) groups. All rats were administered PSZ orally followed by VCR intravenously 4 h later...

Introduction. Mural intestinal hematoma (MIH) is an uncommon complication of anticoagulant therapy. Hemorrhagic shock has been rarely reported as a revealing modality. Results. We report two cases of shock induced by mural intestinal hematoma in patients under oral anticoagulant for aortic prosthetic valve and atrial fibrillation. Patients were admitted to the ICU for gastrointestinal tract bleeding associated with hemodynamic instability. After resuscitation, an abdominal CT scan has confirmed the diagnosis showing an extensive hematoma...

BACKGROUND AND OBJECTIVE: To evaluate the feasibility and safety of silicone oil (SO) removal in cases of gunshot perforating eye injuries (PEI). PATIENTS AND METHODS: A retrospective, consecutive, interventional study from medical records regarding cases of gunshot PEI during the periods of Egyptian political instability (January 2011 until December 2013). The main outcomes were to evaluate the feasibility of SO removal in cases of gunshot PEI and management of retinal detachment (RD) after SO removal in such cases...

BACKGROUND: Uric acid is the end product of purine metabolism in humans and its increased level in serum leads to hyperuricemia. Among the different regulatory factors to control the level of uric acid in humans, xanthine oxidase (XO) is a well-established pharmacological target, as it is directly involved in uric acid production. METHODS: The aim of the study was to present a systematic approach to analyze the xanthine oxidase inhibition studies from in vitro leading to in vivo...

OBJECTIVE: Smoking negatively affects fertility and the rate of other endometrial diseases. To determine the effect of smoking on endometrial physiology, we evaluated 2 endometrial regulatory cytokines and receptivity markers, C-X-C motif chemokine ligand 12 (CXCL12) and fibroblast growth factor 2 (FGF2), both in vitro and in vivo. STUDY DESIGN: The human endometrial stromal cell line (HESC) and primary human endometrial stromal cells were treated with cigarette smoking extract (CSE) or with vehicle control...

Depression is one of the most common psychiatric disorders worldwide, with over 350 million people affected. Current methods to screen for and assess depression depend almost entirely on clinical interviews and self-report scales. While useful, such measures lack objective, systematic, and efficient ways of incorporating behavioral observations that are strong indicators of depression presence and severity. Using dynamics of facial and head movement and vocalization, we trained classifiers to detect three levels of depression severity...
