<P> Biopolymer-soil technology is currently recognized as an environmentally friendly soil improvement method for geotechnical engineering practices. However, concerns exist regarding biopolymer fine-soil applications because the performance of biopolymers is based on an electrical interaction with clay or a pore fluid. Thus, the effect of water content and pore-fluid chemistry on biopolymer behavior in soil must first be clarified in terms of biopolymer applications. In this study, the liquid limits of xanthan gum biopolymer-treated clay-sand mixtures (clayey silt, kaolinite, montmorillonite, and sand) were obtained using three chemically distinct pore fluids (deionized water, 2 mol/L NaCl brine, and kerosene). Xanthan gum has contrary effects to the soil consistency, where the liquid limit can decrease via xanthan gum-induced particle aggregation or increase due to xanthan gum hydrogel formation. The clay-mineral type governed the xanthan gum behavior in the deionized water, while the pore-fluid chemistry governed the xanthan gum behavior in the brine and the kerosene. </P>

<P> Nonalcoholic fatty liver disease is the most common chronic liver disease and can present with advanced fibrosis or nonalcoholic steatohepatitis. The purpose of this study was to investigate the effect of a 7-day intense physical activity intervention on liver fat content in children with obesity. Fifty-seven obese children (mean body mass index: 26.5 ± 3.2 kg/m<SUP>2</SUP>; mean age: 12.0 ± 0.8 years) participated in a 7-day physical activity program. All participants were housed together, and their food intake and energy expenditure were strictly controlled. Anthropometric measurements, abdominal computerized tomography scans, and blood analyses were conducted at baseline and post-intervention. Participants lost weight by 2.53 ± 0.85 kg on average (61.0 ± 9.8 vs. 58.5 ± 9.5 kg, p @@<@@ 0.05), fat mass (16.7 ± 5.1 vs. 15.7 ± 4.9 kg, p @@<@@ 0.05), and serum insulin (13.7 ± 6.7 vs. 3.5 ± 2.0 μU/mL, p @@<@@ 0.05). However, liver fat content was increased, presented as liver-to-spleen ratio (LSR) where lower LSR represents higher liver fat content. The intervention increased aspartate transaminase level (29.42 ± 6.78 IU/L vs. 33.50 ± 9.60 IU/L, p @@<@@ 0.001). The change in liver fat content was not associated with the change in fasting insulin and liver enzymes. Short-term intense physical activity increased liver fat content independent of change in fasting insulin level and liver enzymes. This is the first human study to report increased liver fat content after physical activity-induced rapid weight loss. </P>

<P> The Rsv4 gene confers resistance to all the known strain groups of soybean mosaic virus in soybean (Glycine max (L.) Merr.). To construct a fine genetic map near Rsv4 in soybean, we employed a comparative genomics approach that used genome sequence information of the model legume Lotus japonicus. Sequences of the soybean expressed sequence tags (ESTs) AI856415 and BF070293 mapping to one side of the Rsv4 gene showed high similarity with gene sequences of the transformation-competent artificial chromosome (TAC) clone LjT32P24 of Lotus. LjT32P24 is tightly linked to another sequenced TAC clone, LjT26I01, in Lotus. A new marker, AW307114A, developed from soybean EST AW307114, which is homologous to a Lotus gene within LjT26I01, was mapped to the other side of the Rsv4 gene. The identification of the microsyntenic relationship facilitated the development of additional 2 EST markers between BF070293-S and AW307114A bracketing the Rsv4 gene. Several other markers developed in this study were mapped to putative homoeologous or duplicated chromosomal regions in soybean. Alignment between the soybean maps indicated that Rsv4 is located near a local chromosomal rearrangement. This targeted comparative mapping serves to provide a foundation for marker-assisted selection and cloning of the Rsv4 gene.Key words: comparative genomics, resistance gene, lotus, soybean. </P>

<P> Hordeum vulgare subsp. spontaneum is the progenitor of cultivated barley (Hordeum vulgare L.). Domestication combined with plant breeding has led to the morphological and agronomic characteristics of modern barley cultivars. The objective of this study was to map the genetic factors that morphologically and agronomically differentiate wild barley from modern barley cultivars. To address this objective, we identified quantitative trait loci (QTLs) associated with plant height, flag leaf width, spike length, spike width, glume length in relation to seed length, awn length, fragility of ear rachis, endosperm width and groove depth, heading date, flag leaf length, number of tillers per plant, and kernel color in a Harrington/OUH602 advanced backcross (BC2F8) population. This population was genotyped with 113 simple sequence repeat markers. Thirty QTLs were identified, of which 16 were newly identified in this study. One to 4 QTLs were identified for each of the traits except glume length, for which no QTL was detected. The portion of phenotypic variation accounted for by individual QTLs ranged from about 9% to 54%. For traits with more than one QTL, the phenotypic variation explained ranged from 25% to 71%. Taken together, our results reveal the genetic architecture of morphological and agronomic traits that differentiate wild from cultivated barley. </P>

<P> Research involving whitening agents requires several steps of experimentation, and the initial step is to test whitening agents with human melanocytes and those with human tyrosinase. Unfortunately, it takes a long time to gather human melanocytes, and these cells have some limitations when it comes to performing experiments, such as their passage difficulties and their cost. In this study, we suggest that the TXM13 human melanoma cells could be a useful cell candidate for studying human tyrosinase inhibition and depigmentation. We applied a tyrosinase inhibitor, such as dithioglycerine (DTGC), to validate the cell line's usefulness, and we tested the effect of DTGC on TXM13 melanogenesis. The results showed that human tyrosinase from TXM13 was appropriate, according to the inhibition kinetics, and that the conspicuous depigmentation of TXM13 occurred after DTGC treatment without downregulating the tyrosinase expression level. When taken together, our findings provide useful information regarding the use of the TXM13 melanoma cells for the development of whitening agents.Key words: TXM13, pigment cell, human tyrosinase, whitening agent. </P>
