Protective Effect of Red Light-Emitting Diode against UV-B Radiation-Induced Skin Damage in SKH:HR-2 Hairless Mice.

In this in vivo study on hairless mice, we examined the effects of light-emitting diode (LED) treatment applied prior to ultraviolet B (UVB) irradiation. We found that pre-treating with LED improved skin morphological and histopathological conditions compared to those only exposed to UVB irradiation. In our study, histological evaluation of collagen and elastic fibers after LED treatment prior to UVB irradiation showed that this pretreatment significantly enhanced the quality of fibers, which were otherwise poor in density and irregularly arranged due to UV exposure alone.

Structural basis of the specific interaction of SMRT corepressor with histone deacetylase 4.

Modification of chromatin and related transcription factors by histone deacetylases (HDACs) is one of the major strategies for controlling gene expression in eukaryotes. The HDAC domains of class IIa HDACs repress the respective target genes by interacting with the C-terminal region of the silencing mediator for retinoid and thyroid receptor (SMRT) repression domain 3 (SRD3c). However, latent catalytic activity suggests that their roles as deacetylases in gene regulation are unclear.

Time and Intervention Effects of Daily Almond Intake on the Changes of Lipid Profile and Body Composition Among Free-Living Healthy Adults.

Favorable health benefits of almond have been shown in several previous studies. However, repeated measures, randomized, controlled trials to investigate the changes due to almond intake based on the time effects have not yet been reported. The current study was conducted to evaluate the effects of daily almond intake on changes in body composition and lipid profiles for 20 weeks with four measurements among healthy adults.

The effects of daily intake timing of almond on the body composition and blood lipid profile of healthy adults.

Background/objectives: Timing of almond intake during a day may result differently in the perspectives of body composition and changes of lipid profile. The current study was conducted to compare the effects of daily almond intake as a preload versus as a snack on body composition, blood lipid profile, and oxidative and inflammation indicators among young Korean adults aged 20-39 years old.

Subjects/methods: Participants were randomly assigned to one of three groups: a pre-meal almond group (PM), a snack almond group (SN) in which participants were instructed to consume 56 g of almonds either as a preload before meals or as a snack between meals, respectively, and a control group (CL) in which participants were provided high-carbohydrate iso-caloric control food.

The differential effects of changes in individual macronutrient intake on changes in lipid concentrations during childhood: From the Ewha Birth & Growth Cohort.

Background & Aims: High carbohydrate or fat intake is responsible for abnormal lipid concentrations in adults, but few studies of children have been reported. Using data from a Korean children's cohort study, we assessed the association between macronutrient intake and lipid profile with a longitudinal association during a 4-year follow-up.

Methods: Using 2 days of 24-h dietary data obtained at 3 (n = 323) and 7 (n = 292) years old from the Ewha Birth & Growth Cohort, we calculated changes (n = 103) in macronutrient intake in terms of energy-adjusted intake and percent total energy for nutrients.

Hypoallergenic and Physicochemical Properties of the A2 β-Casein Fractionof Goat Milk.

Goat milk has a protein composition similar to that of breast milk and contains abundant nutrients, but its use in functional foods is rather limited in comparison to milk from other sources. The aim of this study was to prepare a goat A2 β-casein fraction with improved digestibility and hypoallergenic properties. We investigated the optimal conditions for the separation of A2 β-casein fraction from goat milk by pH adjustment to pH 4.

Which Diet-Related Behaviors in Childhood Influence a Healthier Dietary Pattern? From the Ewha Birth and Growth Cohort.

This study was performed to examine how childhood dietary patterns change over the short term and which changes in diet-related behaviors influence later changes in individual dietary patterns. Using food frequency questionnaire data obtained from children at 7 and 9 years of age from the Ewha Birth and Growth Cohort, we examined dietary patterns by principal component analysis. We calculated the individual changes in dietary pattern scores.

Molecular Characterization of Two Monoclonal Antibodies against the Same Epitope on B-Cell Receptor Associated Protein 31.

Previously, we showed that B-cell receptor associated protein 31 (BAP31), an endoplasmic reticulum (ER) membrane chaperone, is also expressed on the cell surface by two monoclonal antibodies (MAbs) 297-D4 and 144-A8. Both MAbs recognize the same linear epitope on the C-terminal domain of BAP31, although they were independently established. Here, flow cytometric analysis showed that 144-A8 had additional binding properties to some cells, as compared to 297-D4.

Hydrolysis by Alcalase Improves Hypoallergenic Properties of Goat Milk Protein.

Goat milk is highly nutritious and is consumed in many countries, but the development of functional foods from goat milk has been slow compared to that for other types of milk. The aim of this study was to develop a goat milk protein hydrolysate (GMPH) with enhanced digestibility and better hypoallergenic properties in comparison with other protein sources such as ovalbumin and soy protein. Goat milk protein was digested with four commercial food-grade proteases (separately) under various conditions to achieve the best hydrolysis of αs -casein and β-lactoglobulin.

Epitope Mapping of Antibodies Suggests the Novel Membrane Topology of B-Cell Receptor Associated Protein 31 on the Cell Surface of Embryonic Stem Cells: The Novel Membrane Topology of BAP31.

When located in the endoplasmic reticulum (ER) membrane, B-cell receptor associated protein 31 (BAP31) is involved in the export of secreted proteins from the ER to the plasma membrane. In a previous study, we generated two monoclonal antibodies (mAbs), 297-D4 and 144-A8, that bound to surface molecules on human embryonic stem cells (hESCs), but not to surface molecules on mouse embryonic stem cells (mESCs). Subsequent studies revealed that the mAbs recognized BAP31 on the surface of hESCs.

Solution structure of the porcine sapovirus VPg core reveals a stable three-helical bundle with a conserved surface patch.

Viral protein genome-linked (VPg) proteins play a critical role in the life cycle of vertebrate and plant positive-sense RNA viruses by acting as a protein primer for genome replication and as a protein cap for translation initiation. Here we report the solution structure of the porcine sapovirus VPg core (VPg(C)) determined by multi-dimensional NMR spectroscopy. The structure of VPg(C) is composed of three α-helices stabilized by several conserved hydrophobic residues that form a helical bundle core similar to that of feline calicivirus VPg.

Improved islet transplantation outcome by the co-delivery of siRNAs for iNOS and 17β-estradiol using an R3V6 peptide carrier.

Silencing target genes such as inducible nitric oxide synthase (iNOS) using small interfering double-stranded RNA (siRNA) in islet cells has been attempted to enhance the survival of transplanted islets. However, the efficient and safe delivery of siRNA into intact islets is challenging. Here, we prepared R3V6 peptides containing a three-arginine stretch and a six-valine stretch, which form micelles with hydrophobic valine cores and cationic arginine surfaces in aqueous solution, to co-deliver siRNA and cytoprotective hydrophobic drugs to islet cells.
