The objective of the present study is to produce base layer winter active sportswear fabrics using natural and synthetic fibres and their blends which will deliver good comfort properties. Polyester, wool and bamboo fibres were selected for this study. Polyester is the most common fibre used in sportswear, wool is increasingly being used in sportswear and bamboo is a relatively new fibre that offers properties suitable for base layer sportswear. Bamboo is also regarded as a 'green' and eco-sustainable fibre.

The objective of this research is to study the effect of onset of physical fatigue/stress during isometric and dynamic contractions based on the changes in physiological signal i.e. SEMG. Therefore, the intention of this present investigation is to assess the repeatability of common muscle fatigue measures, including amplitude and spectral measures of EMG and further, to determine the adequacy of different measures in detection of onset of localized muscle fatigue.

An experiment was conducted to study the effect of edible coating and packaging material on physiological and sensory quality of litchi fruits. For this, mature litchi fruits were harvested from HRC, Patharchatta and the selected fruits were treated with Guar Gum, Xanthan Gum and Methyl cellulose (low viscosity and high viscosity)as edible coating at different concentration (0.5%, 1.0%, 2.0%, 2.5%) and stored at 4 ± 1 °C under 90 ± 5% RH.

The serpin plasminogen activator inhibitor type 1 (PAI-1) plays an important role in physiological processes such as thrombolysis and ®brinolysis, as well as pathophysiological processes such as thrombosis, tumor invasion and metas-tasis. In addition to inhibiting serine proteases, mainly tissue-type (tPA) and urokinase-type (uPA) plasminogen activators, PAI-1 interacts with di€erent components of the extracellular matrix, i.e. ®brin, heparin (Hep) and vitronectin (Vn).

Lactoferrin (LF) is a Fe 3+ -binding glycoprotein, first recognized in milk and then in other human epithelial secretions and barrier fluids. Many different functions have been attributed to LF, including protection from iron-induced lipid peroxidation, immunomodulation and cell growthregulation, DNA binding, and transcriptional acti-vation. Its physiological role is still unclear, but it has been suggested to be responsible for primary defense against microbial and viral infection.

Ca 2+ and cAMP are ubiquitous second messengers in euk-aryotes and control numerous physiological responses ran-ging fromfertilization to cell death induction 1 . Todistinguish between these different responses, their subtle regulation in time, space and amplitude is needed. Therefore, the char-acterization of the signalling process requires measurement of secondmessengers with tools of precise localization, high dynamic range and as little disturbance of cell physiology as possible.

Plasminogen activator inhibitor type-2 (PAI-2) is a nonconventional serine protease inhibitor (serpin) with unique and tantalizing properties that is generally considered to be an authentic and physiological inhibitor of uro-kinase. However, the fact that only a small percentage of PAI-2 is secreted has been a long-standing argument for alternative roles for this serpin.

To assess the expression and physiological role of the mitochondrial NAD + -independent lactate dehydrogenase (iLDH) inEuglena gracilis, cells were grown with different carbon sources, and theD-andL-iLDHactivities and several key metabolic intermediates were examined. iLDH activity was significant throughout the growth period, increasing by three- to fourfold from latency to the stationary phase. Intracellular levels ofD-andL-lactate were high (5–40 mM) fromthe start of the culture and increased (20–80 mM)when the stationaryphasewas entered....

In the nematodeCaenorhabditis elegans, 40 genes code for astacin-likeproteins (nematodeastacins,NAS).The astacins are metalloproteases present in bacteria, invertebrates and vertebrates and serve avarietyof physiological functions like digestion, hatching, peptide processing, morphogenesis and pattern formation. With the exception of one distorted pseudogene, all the otherC. elegansastacins are expressed and are evidently functional. For 13 genes we found splicing patterns differing from the Genefinder predictions in WormBase, sometimes markedly....

The development of targeted probes (based on the molecular engineering of luminescent or fluorescent proteins) has allowed the specific measure-ment of [Ca 2+ ] in intracellular organelles or cytoplasmic subdomains. This approach gave novel information on different aspects of cellular Ca 2+ homeostasis. Regarding mitochondria, it was possible to demonstrate that, upon physiological stimulation of cells, Ca 2+ is rapidly accumulated in the matrix.

The interaction between the human copper(I) chaperone, HAH1, and one of its two physiological partners, the Menkes disease protein (ATP7A), was investigated in solution using heteronuclear NMR. The study was carried out through titrations involving HAH1 and either the second or the fifth soluble domains of ATP7A (MNK2 and MNK5, respectively), in the pres-ence of copper(I). The copper-transfer properties of MNK2 and MNK5 are similar, and differ significantly from those previously observed for the yeast homologous system. ...

Inorder to clarify the role of cytochrome innitrate reductase we have performed spectrophotometric and stopped-flow kinetic studies of reduction and oxidation of the cytochrome hemes with analogues of physiological quinones, using menadione as an analogue of menaquinone and duro-quinone as an analogue of ubiquinone, and comparing the results with those obtained with dithionite. The spectropho-tometric studies indicate that reduction of the cytochrome hemes varies according to the analogue of quinoneused, and in no cases is it complete....

G-rich GT oligonucleotides with a different content of G clusters have been evaluated for their ability to exert cytotoxicity and to bind to nuclear-associated proteins in T-lymphoblast CCRF-CEM cells. Only the oligomers that did not form G-based structures or had a poor structure, under physiological conditions, were able to exert significant cellular growth inhibition effect.

The protein ataxin-3 is responsible for spinocerebellar ataxia type 3, a neu-rodegenerative disease triggered when the length of a stretch of consecutive glutamines exceeds a critical threshold. Different physiologic roles have been suggested for this protein. More specifically, recent papers have shown that the highly conserved N-terminal Josephin domain of ataxin-3 binds ubiquitin and has ubiquitin hydrolase activity, thanks to a catalytic device specific to cysteine proteases.

The nitrite reductase activity of deoxyhemoglobin has received much recent interest because the nitric oxide produced in this reaction may participate in blood flow regulation during hypoxia. The present study used spectral deconvolution to characterize the reaction of nitrite with carp and rabbit hemoglobin at different constant oxygen tensions that generate the full range of physiological relevant oxygen saturations.
