Protective effect of gel form of gastric gavage applicated aloe vera on ischemia reperfusion injury in renal and lung tissue.

The aloe vera plant has become increasingly popular in recent years. This study aimed to research the effect of aloe vera to prevent renal and lung tissue damage in an experimental ischemia-reperfusion (I/R) injury model. The study included 21 male Wistar Albino rats, which were categorized into control group, n = 7 (no procedures), Sham group n = 7 (I/R); and aloe vera therapy group, n = 7 (aloe vera and I/R).

Evaluation of the Approaches of the Anaesthesiologists on Maintenance of Anaesthesia Machines.

Objective: In this study, we aimed to discuss the level of knowledge and approach on 'maintenance, calibration and cleaning of anaesthesia devices' among anaesthesiologists in Turkey.

Methods: A questionnaire was prepared with 21 questions based on the Google document system, and these questionnaires were sent to the anaesthesiologists via e-mail.

Results: Overall, 226 anaesthesiologists answered our survey.

Type of anesthesia affects neonatal wellbeing and frequency of transient tachypnea in elective cesarean sections.

Objective: We aimed to assess whether the type of anesthesia in cesarean section (C/S) (spinal anesthesia, SA versus general anesthesia, GA) has an effect or not on umblical vein blood gas analysis and APGAR scores of term neonates and development of transient tachypnea of the newborn (TTN).

Methods: The data of 172 procedure (85, GA versus 87, SA) were collected retrospectively. Results of umblical vein blood gas analysis, APGAR scores at first and fifth minutes and presence of TTN from in-hospital files' of neonates were examined.

Ni and Cu incorporated mesoporous nanocomposite catalytic materials.

Nickel and copper incorporated MCM-41-like mesoporous nanocomposite materials prepared by the direct hydrothermal synthesis and the impregnation procedures showed highly attractive pore structure and surface area results for catalytic applications. The XRD patterns showed that characteristic MCM-41 structure was preserved for the materials synthesized following an impregnation procedure before the calcination step. The surface area of the Cu impregnated material with a quite high Cu/Si atomic ratio (0.

Adsorption of Basic Yellow 28 from aqueous solutions with clinoptilolite and amberlite.

The objective of this study was to investigate the adsorption of Basic Yellow 28 that is a cationic dye on clinoptilolite and amberlite XAD-4. Both equilibrium and batch rate adsorption in aqueous solutions of the dyestuff were investigated. Adsorption rate data were analysed using the pseudo-first order kinetic model of Lagergren and the pseudo-second order model to determine adsorption rate constants at 20, 30 and 40 degrees C.

Effect of pH in an Aqueous Medium on the Surface Area, Pore Size Distribution, Density, and Porosity of Montmorillonite.

Surface area, pore volume distribution, and porosity of montmorillonite are determined after being exposed to aqueous solutions with various pH values. For measurement, after each pH treatment the clay samples were freeze-dried in order to keep the structure of the clay same as that in the aqueous solution. Surface area and pore size distribution measurements were performed on an unmodified and four pH (2.
