Viroporins, Examples of the Two-Stage Membrane Protein Folding Model
2015
Viroporins are small, α-helical, hydrophobic virus encoded proteins, engineered to form homo-oligomeric hydrophilic pores in the host membrane. Viroporins participate in multiple steps of the viral life cycle, from entry to budding. As any other membrane protein, viroporins have to find the way to bury their hydrophobic regions into the lipid bilayer. Once within the membrane, the hydrophobic helices of viroporins interact with each other to form higher ordered structures required to correctly perform their porating activities. This two-step process resembles the two-stage model proposed for membrane protein folding by Engelman and Poppot. In this review we use the membrane protein folding …

Lesiones bucales en un grupo de pacientes con trasplante renal
2005
Objetivo: Determinar la prevalencia de lesiones de la mucosa bucal (LB) en un grupo de pacientes con trasplante renal (TR), y analizar las posibles asociaciones de las lesiones entre sí, con el uso de fármacos y con variables clínicas y de laboratorio relevantes. Metodología. Estudio transversal, en el que se examinó a pacientes consecutivos con TR de la consulta de nefrología de un hospital General de Zona del Instituto Mexicano del Seguro Social. Se determinó la frecuencia y el tipo de lesiones bucales. Se analizaron las posibles asociaciones de las LB entre sí y con la cuenta de leucocitos totales, la función renal, el índice de higiene oral simplificado (IHO-S), los niveles de ciclospor…
Cephalosporin resistantEscherichia colifrom cancer patients in Cairo, Egypt
2013
Cephalosporin-resistant Escherichia coli has been increasingly reported worldwide. In this study, 32 cephalosporin resistant E. coli isolates identified from cancer patients in Cairo, Egypt in 2009–2010 were analyzed. Twenty-three were of phylogenetic group D, seven A and one each B1 and B2. By rep-PCR 15 phylogroup D isolates were grouped in four clusters, one with sequence type (ST) 405 and three ST68. Seventeen isolates showed single patterns. blaCTX-M-15 and aac(6')-Ib-cr were the most common resistance determinants. blaOXA-48 and blaVIM were also detected. Multidrug resistant E. coli seriously affects healthcare, especially in immunocompromised hosts, such as cancer patients.
Neural Networks Ensemble for Cyclosporine Concentration Monitoring
2001
This paper proposes the use of neural networks ensemble for predicting the cyclosporine A (CyA)concen tration in kidney transplant patients. In order to optimize clinical outcomes and to reduce the cost associated with patient care, accurate prediction of CyA concentrations is the main objective of therapeutic drug monitoring. Thirty-two renal allograft patients and different factors (age, weight, gender, creatinine and post-transplantation days, together with past dosages and concentrations)w ere studied to obtain the best models. Three kinds of networks (multilayer perceptron, FIR network, Elman recurrent network) and the formation of neural-network ensembles were used. The FIR network, y…
Eosinophils, pruritus and psoriasis: effects of treatment with etretinate or cyclosporin-A
1998
Abstract Background The antipsoriatic drugs cyclosporin A (CyA) and etretinate have been found to influence proinflammatory eosinophilic leukocytes and pruritus. Aim We compared the number of blood eosinophils, concentration of serum eosinophil cationic protein (ECP), and pruritus in patients with psoriasis treated with either CyA or etretinate. Study design Patients with psoriasis vulgaris were randomly assigned to treatment for 10 weeks with either CyA ( n =21) or etretinate ( n =10). The psoriasis area-and-severity index (PASI-score) and pruritus (according to a 0–3 scale) served as clinical parameters, the blood esosinophil counts (Coulter Counter) and the serum ECP (RIA, Pharmacia) as …
