The purposes of this study were to produce polysaccharides from red pepper stems using different extraction methods and evaluate their chemical composition, in vitro biological capacities, and rheological properties. Two polysaccharides were extracted from red pepper stems using an autoclave and alkali treatments, and the extracts were named PAU and PAL, respectively. The contents of total phen...

Phenylalanine ammonia-lyase (PAL) is a key enzyme in pathogen defence, stress response and secondary metabolism and is subject to post-translational phosphorylation. In order to address the significance of this phenomenon it is necessary to identify the protein kinase (PK) responsible and place it in its regulatory circuit. Using protoplast transient expression of Arabidopsis kinase genes coupl...

PURPOSE The purpose of the current study was to investigate steps per day (steps/d) and physical activity level (PAL) in Korean elementary school children having normal weight (normal-weight). We also clarified whether a gender difference exited between steps/d and PAL. METHODS Children aged 9 to 12 y were recruited from two elementary schools located in different urban districts in Korea. Th...

The pal 4 nuclease (termed I-Sce II) is encoded in the group I al 4 intron of the COX I gene of Saccharomyces cerevisiae. It introduces a specific double-strand break at the junction of the two exons A4-A5 and thus mediates the insertion of the intron into an intronless strain. To define the sequence recognized by pal 4 we introduced 35 single mutations in its target sequence and examined their...

Metabolic channeling has been proposed to occur at the entry point into plant phenylpropanoid biosynthesis. To determine whether isoforms of L-Phe ammonia-lyase (PAL), the first enzyme in the pathway, can associate with the next enzyme, the endomembrane-bound cinnamate 4-hydroxylase (C4H), to facilitate channeling, we generated transgenic tobacco (Nicotiana tabacum) plants independently express...

Paired Associated learning (PAL) as part of the Cambridge Neurological Test Battery (CANTAB) is a task of great potential for disease research. The initial interest in this task was sparked by studies of patients with Alzheimer’s disease (AD) or mild cognitive impairment (MCI), often viewed as a prodromal form of AD. AD patients were highly impaired on PAL, more importantly, so were a sub-popul...

OBJECTIVE The aim of the present study was to examine the effects of a new antipsychotic drug paliperidone palmitate on hemogram and coagulation parameters in rats. MATERIALS AND METHODS Experiments were performed on 22 female albino Wistar rats (8-12 weeks old). Control group was given drinking water as vehicle (0.3 mL). PAL-1 rats were given 1 mg/kg paliperidone palmitate (in 0.3 mL drinkin...

BACKGROUND Peer-assisted learning (PAL) has become a well-accepted teaching method within medical education. However, descriptions of on-ward PAL programs are rare. A focus group analysis of a newly established PAL program on an internal medicine ward was conducted to provide insights into PAL teaching from a student perspective. PURPOSE To provide insights into students' experiences regardin...

We report two studies examining the relations among three paired-associate learning (PAL) tasks (visual-visual, verbal-verbal, and visual-verbal), phoneme deletion, and single-word and nonword reading ability. Correlations between the PAL tasks and reading were strongest for the visual-verbal task. Path analyses showed that both phoneme deletion and visual-verbal PAL were unique predictors of a...
