Volatile compound profiles of probiotic yogurt samples prepared using 8 different prebiotic combinations were analyzed using gas chromatography/mass spectrometry (GC-MS) with solid phase micro extraction during 28 days of storage. A total of 40 volatile compounds were identified in yogurt samples during storage consisting of 2 aldehydes, 6 ketones, 4 alcohols, 6 acids, 5 esters, 3 terpenes, 3 aromatic hydrocarbons, and 12 aliphatic hydro-carbons. Acetaldehyde, diacetyl, acetoin, 2-heptanone, ethanol, isoamyl alcohol, acetic acid, caproic acid, caprilic acid, and capric acid were the major volatile compounds in all probiotic yogurt samples. © 2015, The Korean Society of Food Science and Technology and Springer Science+Business Media Dordrecht.

In this study, porous Mg-10Al alloy specimens were fabricated by conventional powder metallurgy sintering method for use as hydrogen storage fuel cells. The porosity, pore morphologies, phases in microstructure, and hardness of specimens, which were previously pressed at different cold compaction pressures and then sintered at 465C, were investigated. The Mg phase desired for hydrogen storage was the predominant phase for all of the specimens. In addition, several second phases, such as the Mg 3.1Al 0.9 and the Mg 17Al 12 phases, formed in the microstructures. As a result of increasing cold compaction pressure, the porosity and Mg phase decreased, while the hardness and Mg 17Al 12 phase increased. © 2012 Taylor and Francis Group, LLC.

In the present study, we contribute to the diversity of marine meiofauna of Turkey by describing both sexes of Schizopera karanovici sp. nov., which were collected from the intertidal zone of Alata beach, Turkey. The new species is closely related to S. lagrecai Pesce 1988, S. minuta Noodt 1955, and S. variseta Bozic, 1964, but can easily be differentiated from its congeners by the width/length ratio and setal organisation of the caudal rami and P5. © 2014, Senckenberg Gesellschaft für Naturforschung and Springer-Verlag Berlin Heidelberg.

Herein I investigated the impact of vitamin D on glycemic control in patients with type 2 diabetes mellitus. 128 patients with type 2 diabetes mellitus were enrolled in this study (mean (S.D) age: 57.7±10 years, 26.6% were female). It was collected clinical and laboratory characteristics of patients from hospital records retrospectively. Patients were divided into two groups according to the HBA1c values: good glycemic control (HbA1c≤7%) and poor glycemic control (HbA1c>7%). It was compared 25 hydroxyvitamin (OH) D and other collected laboratory parameters between the two groups. The vitamin D deficiency rate was 98.3%. In the result with ROC curve analyzes and Mann Whitney U test vitamin D was’nt significantly associated with glycemic control (P value >0.05). Among other parameters result with ROC curve analyzes and student t test RDW-CV was found to be significantly associated with glycemic control (P value <0.05). Although high level of vitamin D deficiency, present study indicated that vitamin D was’nt significantly related to glycemic control in type 2 diyabetes mellitus. Even so RDW-CV was significantly related to glycemic control. © 2015, E-Century Publishing Corporation. All Rights Reserved.

An effective-field theory with correlations is developed for a mixed spin-1 and spin-3/2 Ising system with two alternative layers of a honeycomb lattice. Spin-1 atoms and spin-3/2 atoms are distributed in alternative layers of a honeycomb lattice. We consider that the nearest-neighbor spins of each layer are coupled ferromagnetically and the interaction between the vertically aligned spins and adjacent spins are coupled either ferromagnetically or antiferromagnetically depending on the sign of the bilinear exchange interactions. We investigate the temperature dependence of the total magnetization to find the compensation points and to determine the type of compensation behavior. We present the phase diagrams in different planes for h=0, and the phase diagrams contain the paramagnetic, nonmagnetic and ferrimagnetic phases. The system also presents a tricritical behavior besides multicritical point (A), isolated critical point (C) and double critical end point (B) depending on the interaction parameters. © 2010 Elsevier Ltd.
