BACKGROUND Musculus gastrocnemius tightness (MGT) can be diagnosed by comparing ankle dorsiflexion (ADF) with the knee extended and flexed. Although various measurement techniques exist, the degree of knee flexion needed to eliminate the effect of the gastrocnemius on ADF is still unknown. The aim of this study was to identify the minimal degree of knee flexion required to eliminate the restric...

Cardiovascular disease risk is associated with excess body weight and elevated plasma free fatty acid (FFA) concentrations. This study examines how an alternate-day fasting (ADF) diet high (HF) or low (LF) in fat affects plasma FFA profiles in the context of weight loss, and changes in body composition and lipid profiles. After a 2-week weight maintenance period, 29 women (BMI 30-39.9 kg/m(2)) ...

analyzed as a Latin-square design using PROC MIXED in SAS. Forage quality was analyzed as a completely random design using PROC GLM in SAS. The BMR varieties were lower (P < 0.01) in ADF and NDF at all harvest dates, while N concentrations were not affected (P > 0.41) by variety. The A fraction of DM and NDF was higher (P < 0.01) and the C fraction of DM, NDF, and ADF was lower (P < 0.01) for B...

The contribution of this paper is two-fold. First, we derive the asymptotic null distribution of the familiar augmented Dickey-Fuller [ADF] statistics in the case where the shocks follow a linear process driven by infinite variance innovations. We show that these distributions are free of serial correlation nuisance parameters but depend on the tail index of the infinite variance process. These...

PURPOSE Adult T cell leukemia derived factor (ADF) is a human homologue of thioredoxin (hTx), which exhibits scavenging activity with reactive oxygen intermediates. In their previous study, the authors found that after transient retinal ischemia, the expression of thioredoxin in rat retinal pigment epithelium (RPE) layer increased markedly. The present investigation is to determine intracellula...

Spider dragline silk, which exhibits extraordinary strength and toughness, is primarily composed of two related proteins that largely consist of repetitive sequences. In most spiders, the repetitive region of one of these proteins is rich in prolines, which are not present in the repetitive region of the other. The absence of prolines in one component was previously speculated to be essential f...

Proteins of the actin-depolymerizing factor (ADF)/cofilin family have been shown to be crucial for the motility and survival of apicomplexan parasites. However, the mechanisms by which ADF proteins fulfill their function remain poorly understood. In this study, we investigate the comparative activities of ADF proteins from Toxoplasma gondii and Plasmodium falciparum, the human malaria parasite,...

The effect of Arabidopsis thaliana ADF1 and human ADF on the number of filaments in F-actin solutions has been examined using a seeded polymerization assay. ADF did not sever filaments in a catalytic fashion, but decreased the steady-state length distribution of actin filaments in correlation with its effect on actin dynamics. The increase in filament number was modest as compared with the larg...

An adaptive enhancement method is proposed to improve recognition accuracy on the outputs of blind speech separation (BSS) system based on adaptive decorrelation filtering (ADF) in diffuse noise. A divide and conquer strategy is taken to deal with the noise effects on both system adaptation and ADF outputs. First, fast noise compensation (NC) is performed for filter adaptation, forcing ADF to f...

This study investigated the effects of using Socratic questioning to enhance students’ critical thinking (CT) skills in asynchronous discussion forums (ADF) in university-level distance learning courses. The research effort empirically examined two coherent subjects: (a) the efficacy of teaching and modeling Socratic questioning for developing students’ CT skills in ADF and (b) the persistence ...
