The aim of this study was to determine the optimal heat treatment conditions for enhancement of pressed silk-mediated 3D-like proliferation of normal human dermal fibroblasts, as well as to determine the responses to heat shock of cells and intracellular signaling pathways. The beginning of 3D-like pattern formation of cells was observed in the second week after the start of the experiment. The...

Introduction: The present study aimed to explore protective mechanisms of hypothermia against mild cold and heat stress on highly proliferative homogeneous human Neural Precursor Cells (NPCs) derived from Subventricular Zone (SVZ) of human fetal brain.  Methods: CD133+ve enriched undifferentiated and differentiated human NPCs were exposed to heat stress at 42°C. Then, Western-blot qua...

BACKGROUND Heat shock protein 22 is a member of small heat shock proteins with molecular chaperone activity. Though their multiple functions have been well characterized, there is no report about the association between the polymorphisms of HSP22 and heat tolerance. METHODOLOGY Three single nucleotide polymorphisms were identified in HSP22 from scallop Chlamys farreri (CfHSP22), and the +94 C...

Background: Cognitive impairment profoundly influences on older adults’ activities and quality of life. Therefore, optimizing and remediating age-associated cognitive decline have great importance. Objectives: To evaluate the effect of 8 weeks (3 day /week) computer based brain training on cognitive performance in old women with Mild Cognitive Impairment (MCI). Materials and Methods...

plate heat exchangers are widely used in industries due to their special characteristics, such as high thermal efficiency, small size, light weight, easy installation, maintenance, and cleaning. the purpose of this study is to consider the effect of depth, angle, and pitch of hemispheric chevrons on the convective heat transfer coefficient and pressure drop. in the simulation of the heat exchan...

Due to the high reflectivity of Ag infrared lasers, there is little research focused on manufacturing and alloys by selective laser melting (SLM) technique. In this paper, characteristics, microstructure, thermal conductivity SLMed Ag, 925Ag, their heat-treated parts were studied. With suitable processing parameters, 925Ag samples with relative densities 91.06% 96.56%, respectively, obtained. e...

Accepted: 27/08/2014 Abstract The kinetics of the degradation of ascorbic acid (AA) in solution during heating at 30, 50, 70 and 90°C for 180 min and during 7 weeks of storage at 4°C and 20°C were investigated. The concentration of AA in solution was determined by the fluorimetric method before heating and storing the samples under different conditions. The retention of AA after heating at 30, ...

The increasing demand of ready-to-eat poultry products has led to serious concerns over product safety, and more emphasis has been placed on thorough cooking of products. In this study, processing conditions and thermal inactivation of Listeria innocua in chicken breast meats were evaluated during convection cooking in a pilot-plant scale air-steam impingement oven. A predictive model was devel...

Total phosphorus analysis was performed on 20 samples of corn distillers dried grains with solubles (DDGS), and three experiments were conducted to determine the bioavailability of P in different samples of DDGS varying in Lys digestibility and heat processing (autoclaving). Relative bioavailability of P was estimated from tibia ash using the slope ratio method after chicks were fed a P-deficie...

UNLABELLED Older adults may be at greater risk for occupational injuries given their reduced capacity to dissipate heat, leading to greater thermal strain and potentially cognitive decrements. PURPOSE To examine the effects of age and increased air velocity, during exercise in humid heat, on information processing and attention. METHODS Nine young (24 ± 1 years) and 9 older (59 ± 1 years) m...
