Due to their high target specificity and binding affinity, therapeutic antibodies are currently the largest class of biotherapeutics. The traditional largely empirical antibody development process is, while mature and robust, cumbersome and has significant limitations. Substantial recent advances in computational and artificial intelligence (AI) technologies are now starting to overcome many of these limitations and are increasingly integrated into development pipelines. Here, we provide an over

Indole is an organic compound that is widespread in microbial communities inhabiting diverse habitats, like the soil environment and human intestines. Measurement of indole production is a traditional method for the identification of microbial species. Escherichia coli can produce millimolar concentrations of indole in the stationary growth phase under nutrient-rich conditions. Indole has received considerable attention because of its remarkable effects on various biological functions of the mic

The phytochemical composition of carotenoids, tocopherols, free sugars, organic acids, L-ascorbic acid, capsaicinoids, and flavonoids in green and red paprika (GP and RP), and paprika leaves (PL) cultivated in Korea were analyzed. The ethanolic extracts of GP, RP, and PL were obtained with 80% ethanol, and their antioxidative activities were determined by measuring their ABTS and DPPH radical scavenging activities. RP showed the highest contents of capsanthin (58.33 ± 3.91 mg/100 g dry weight) a

Quorum sensing (QS)-dependent biofilm formation and motility were controlled by AqsR in Acinetobacter oleivorans DR1. QS-controlled phenotypes appeared to be inhibited by indole and the aqsR mutant had the same phenotypes. We demonstrated that the turnover rate of AqsR became more rapid without the N-acylhomoserine lactone (AHL) signal, and that indole could increase the expression of many protease and chaperone proteins. The addition of exogenous indole decreased the expression of two AqsR-targ

Leuconostoc citreum is one of the most prevalent lactic acid bacteria during the manufacturing process of kimchi, the best-known Korean traditional dish. We have determined the complete genome sequence of L. citreum KM20. It consists of a 1.80-Mb chromosome and four circular plasmids and reveals genes likely involved in kimchi fermentation and its probiotic effects.

The aim of this study was to assess the dimensions of the septal cartilage available for grafting in patients undergoing open rhinoplasty and analyze whether the size of the external nose might be a useful indicator of the size and amount of harvestable septal cartilage. A prospective study was conducted on 55 Korean rhinoplasties. Intraoperative measurement of the harvested septal cartilage with preservation of 10 mm width l-strut was performed. The correlation between the quantity and size of

Oncogenic RAS mutant (RAS^MUT) proteins have been considered undruggable via conventional antibody regimens owing to the intracellular location restricting conventional-antibody accessibility. Here, we report a pan-RAS-targeting IgG antibody, inRas37, which directly targets the intracellularly activated form of various RAS^MUT subtypes after tumor cell-specific internalization into the cytosol to block the interactions with effector proteins, thereby suppressing the downstrea

Expatriation willingness is an important predictor for expatriate success. This study examines the direct and moderating effects of host-country characteristics (economic level and language) and employee's role commitments (work and family) on expatriation willingness. The survey results of 151 married Korean employees show that host-country characteristics and occupational role commitment have direct effects on employees' expatriation willingness and that host-country economic level interacts w

High concentrations of indole are known to be toxic to cells due to perturbations in membrane potential. Here, we report for the first time a transcriptome analysis of a soil model bacterium, Pseudomonas putida KT2440, under indole treatment. We demonstrated that 47 genes are differentially expressed, including 11 genes involved in the tricarboxylic acid cycle (TCA cycle) and 12 genes involved in chaperone and protease functions (hslV, hslU, htpG, grpE, dnaK, ibpA, groEL, groES, clpB, lon-1, lon
