Enfermedad del legionario con afectación hepática predominante

2002

Like other pneumonias due to atypical agents, pneumonia due to Legionela Pneumophila has no characteristic clinical facts, although fever and non-productive cough are almost constant and diarrhea with changes in mental status are common. Hyponatremia and moderate transient hypertransaminasemia are common too. Severe systemic affectation after hematogenous dissemination similar to those described with typical bacterial pneumonias is a prominent difference with other atypical agents, with high mortality rates in the absence of appropriate treatment. Etiological diagnosis is very difficult and it is normally achieved late in the course of the infection. Because of diagnostic difficulties and p…

Development and characterization of xyloglucan-poly(vinyl alcohol) hydrogel membrane for Wireless Smart wound dressings

2018

Abstract Hydrogel-based smart wound dressings that combine the traditional favourable properties of hydrogels as skin care materials with sensing functions of relevant biological parameters for the remote monitoring of wound healing are under development. In particular, lightweight, ultra-high frequency radiofrequency identification (UHF RFID) sensor are adjoined to xyloglucan-poly(vinyl alcohol) hydrogel films to battery-less monitor moisture level of the bandage in contact with the skin, as well as wireless transmit the measured data to an off-body reader. This study investigates the swelling behavior of the hydrogels in contact with simulated biological fluids, and the modification of th…

A comparative study of the population pharmacokinetics of gentamicin and amikacin in newborn patients

1993

SUMMARY The population kinetics of gentamicin and amikacin were studied comparatively in newborn patients with a similar range of gestation age (37.9 ± 2.9 and 36.7 ± 3.6 weeks), postnatal age (13.8 ± 7.4 and 16.7 ± 7 days) and weight (2.85 ± 0.57 and 2.72 ± 0.75 kg), undergoing routine therapeutic monitoring of their serum levels. Individual kinetic analysis of serum drug levels was done using a single-compartment model. The population model employed assumes the existence of residual variability in the serum concentrations and interindividual variability in the pharmacokinetic parameters. The clearance and the apparent distribution volume were calculated for each patient using a two-stage …

Farmacocinética del metronidazol y la gentamicina en dosis única preoperatoria para profilaxis antibiótica quirúrgica en cirugía colorrectal

2008

Objective: To describe, in patients undergoing colorectal surgery (CRS), the pharmacokinetics of a single, prophylactic preoperative dose of 1,500 mg of metronidazole plus 240 mg gentamicin and measure its efficacy in accordance with the accepted pharmacodynamic and microbiological parameters. Method: Thirty-six patients undergoing CRS agreed to participate in the study. Three blood samples were taken from each. Cmax 15 minutes after finishing the infusion of the mixture, CfinIQ on finishing the surgery, and Cmin between 12 and 24 hours post-administration. The concentrations of metronidazole and gentamicin in each simple were measured and the pharmacokinetic parameters were estimated (dV- …

Efficient light-induced phase transitions in halogen-bonded liquid crystals

2016

Here, we present a new family of light-responsive, fluorinated supramolecular liquid crystals (LCs) showing efficient and reversible light-induced LC-to-isotropic phase transitions. Our materials design is based on fluorinated azobenzenes, where the fluorination serves to strengthen the noncovalent interaction with bond-accepting stilbazole molecules, and increase the lifetime of the cis-form of the azobenzene units. The halogen-bonded LCs were characterized by means of X-ray diffraction, hot-stage polarized optical microscopy, and differential scanning calorimetry. Simultaneous analysis of light-induced changes in birefringence, absorption, and optical scattering allowed us to estimate tha…

Photocatalytic solar light H2 production by aqueous glucose reforming

2018

A series of tungsten and nitrogen doped Pt-TiO2 samples were prepared with the aim to extend the TiO2 absorption to the visible light region and to enhance the separation efficiency of the photogenerated electron/hole pairs. The physicochemical features of the powders were characterized by Xray diffraction (XRD), UV/Vis reflectance spectra, specific surface area (SSA) determinations, and transmission electron microscopy (TEM) analyses. The influence of the presence of different doping agents was evaluated, under anaerobic conditions, in the aqueous photo-reforming of glucose to form H2 at ambient pressure and temperature under a halogen lamp or natural solar light irradiation.
