Jiaogulan (Gynostemma pentaphyllum (Thunb.) Makino) is distributed mostly in mountainous areas, in shaded and humid places at 300-3200 meters above sea level. This study was conducted to determine the appropriate application dose of nitrogen for the growth of Jiaogulan under different shading conditions.

The objective of this research was to determine the role of neural feedback and muscle mechanics in the generation of physiological tremor oscillation. This research developed a neuromuscular model to simulate the individual and resulting oscillatory mechanisms of tremor. The oscillations found in EMG signal were also analysed empirically from EMG data from 54 subjects using Hilbert Transform and rectification to obtain the envelope of the signal. The time between rhythmical waveform patterns in the EMG signal, TC was found to be 78ms.

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.

Venoms from crotalid and viperid snakes contain several peptide inhibitors which regulate the proteolytic activities of their snake-venom metalloproteinases (SVMPs) in a reversible manner under physiological conditions. In this report, we describe the high-resolution crystal structures of a SVMP, TM-3, from Taiwan habu (Trimeresurus mucrosquamatus) cocrystallized with the endogenous inhibitors pyroGlu-Asn-Trp (pENW), pyroGlu-Gln-Trp (pEQW) or pyroGlu-Lys-Trp (pEKW).

Human glandular kallikrein 2 (hK2) is a trypsin-like serine protease expressed predominantly in the prostate epithelium. Recently, hK2 has proven to be a useful marker that can be used in combination with prostate specific antigen for screening and diagnosis of prostate cancer. The cleavage by hK2 of certain substrates in the proteolytic cascade suggest that the kallikrein may be involved in prostate cancer development; however, there has been very little other progress toward its biochemical characterization or elucidation of its true physiological role.

There are at least three well-defined signalling cascades engaged directly in the physiological regulation of cardiac circulatory function: theb1-adrenoceptors that control the cardiac contractile apparatus,the renin-angiotensin-aldo-sterone system involved in regulating bloodpressure and the natriuretic peptides contributing at least to the factors determining circulating volume.

S100A1 is a typical representative of a group of EF-hand calcium-binding proteins known as the S100 family. The protein is composed of twoasub-units, each containing two calcium-binding loops (N and C). At physiologi-cal pH (7.2) and NaCl concentration (100 mm), we determined the microscopic binding constants of calcium to S100A1 by analysing the Ca 2+ -titration curves of Trp90 fluorescence for both the native protein and its Glu32fiGln mutant with an inactive N-loop.

The transient receptor potential channel vanilloid receptor subunit 1 (TRPV1) is amolecular integrator of physical and chemical stimuli in the peripheral nociceptor terminals. TRPV1 is an ionotropic channel that plays a critical role in both thermal nociception and inflammatoryhyperalgesia. Structure–function relationships are providing fundamental insights of the modular architecture of this neuronal recep-tor.

ON MONOTONICITY OF SOLUTIONS OF DISCRETE-TIME NONNEGATIVE AND COMPARTMENTAL DYNAMICAL SYSTEMS VIJAYSEKHAR CHELLABOINA, WASSIM M. HADDAD, JAMES M. BAILEY, AND JAYANTHY RAMAKRISHNAN Received 27 October 2003 Nonnegative and compartmental dynamical system models are widespread in biological, physiological, and pharmacological sciences. Since the state variables of these systems are typically masses or concentrations of a physical process, it is of interest to determine necessary and sufficient conditions under which the system states possess monotonic solutions.
