Time Delay Spectrometry (TDS) is a technique used to measure both frequency and time responses of acoustic and electrical systems. TDS theory is presented in both intuitive and mathematical terms. The theoretical limitations of current TDS technology are described. A new extension to TDS theory is introduced which has the potential to signiicantly improve TDS measurements. Implementation issues...

Elevated levels of total dissolved solids (TDS) have been identified as stressors to aquatic life in Central Appalachian coalfield streams. At present there are no aquatic life water quality criteria for TDS in the primary coal-producing Central Appalachian states (KY, VA, WV). In all three states, mining-related impacts on aquatic life have been characterized using measures of benthic macroinv...

Tardive syndrome (TDS) is a potentially permanent and irreversible hyperkinetic movement disorder caused by exposure to dopamine receptor blocking agents. Guidelines published by the American Academy of Neurology recommend pharmacological first-line treatment for TDS with clonazepam (level B), ginkgo biloba (level B), amantadine (level C), and tetrabenazine (level C). Recently, a class II study...

Androgens, the levels of which decrease with ageing, play many physiological roles in various organs. Testosterone deficiency syndrome (TDS) has received widespread attention in the last several years. First-line treatment for TDS should be testosterone replacement therapy (TRT), which is reported to improve several TDS symptoms. Recently, a clinical practice manual for TDS was written and publ...

INTRODUCTION  Testosterone deficiency syndrome (TDS) is characterized by clinical signs of testosterone deficiency in men with reduced testosterone levels. It leads to endothelial dysfunction, which, apart from erectile dysfunction, accelerates atherosclerosis progression. OBJECTIVES  The aim of the study was to evaluate the effect of testosterone supplementation in men with metabolic syndrom...

AIMS The Transdermal Delivery System (TDS) is a liquid formulation that can be applied to the skin via a metered pump spray to deliver drug to the systemic circulation. The aims of this study were to assess the ability of the TDS preparation to deliver testosterone systemically, and to characterize the pharmacokinetic profiles of the hormone in healthy males. METHODS An open label, comparativ...

The aim of this study was to determine whether participating in a cross-country skiing stage race (Tour de Ski; TDS) affects subsequent illness incidence, training, and race performance. Self-reported training and illness data from 44 male and female elite cross-country skiers were included. In total, 127 years of data were collected (2-3 seasons per athlete). Illness incidence, training load, ...

BACKGROUND This study aimed to evaluate the current status of secondary debulking surgery (SDS) and tertiary debulking surgery (TDS; performed for recurrence after SDS) and to assess the overall survival after recurrence of Müllerian epithelial cancer in Japan. We also evaluated the data of patients who underwent a fourth debulking surgery (i.e., quaternary debulking surgery (QDS)). METHODS W...

Isolated preparations of atrial specialized conduction fibers ("plateau" fibers) qualitatively resembled ventricular Purkinje fibers (false tendons) in their response to acetylstrophanthidin. Acetylstrophanthidin in concentrations of 1-3 X 10~ g/ml caused coupled, frequency-dependent transient depolarizations (TDs) in both types of fiber. In free-running strands of plateau fibers the TDs could ...
