Nanobodies are single chain antibodies that have become a highly valuable and versatile tool for biomolecular and therapeutic research. One application field is the stabilization of active states of flexible proteins, among which G-protein coupled receptors represent a very important class of membrane proteins. Here we present the backbone and side-chain assignment of the (1)H, (13)C and (15)N resonances of Nb33 and Nb39, two nanobodies that recognize and stabilize the µ-opioid receptor to opioids in its active agonist-bound conformation...

OBJECTIVE: Preclinical abuse liability assessment is an essential component of tobacco regulatory science. The goal of this project was to evaluate the relative abuse liability of smokeless tobacco products in rats using aqueous extracts of those products. These extracts provide exposure to an extensive range of nicotine and non-nicotine tobacco constituents as occurs in humans. METHODS: Rats were trained to self-administer either nicotine alone or extracts of Camel Snus or Kodiak smokeless tobacco at an equivalent nicotine unit dose...

Sequence-based association studies are at a critical inflexion point with the increasing availability of exome-sequencing data. A popular test of association is the sequence kernel association test (SKAT). Weights are embedded within SKAT to reflect the hypothesized contribution of the variants to the trait variance. Because the true weights are generally unknown, and so are subject to misspecification, we examined the efficiency of a data-driven weighting scheme. We propose the use of a set of theoretically defensible weighting schemes, of which, we assume, the one that gives the largest test statistic is likely to capture best the allele frequency-functional effect relationship...

Tea plant (Camellia sinensis (L.) O. Kuntze) is an important leaf-type woody crop used for producing of non-alcoholic beverages worldwide. The GROWTH-REGULATING FACTOR (GRF) transcription factors cooperated with GRF-INTERACTING FACTOR (GIF) transcriptional coactivators positively regulate leaf development. In the present study, six GRF and two GIF genes were identified and characterized in the leaf transcriptome of C. sinensis, respectively. The alignment results showed that the feature structures of the predicted homologous GRF and GIF proteins of C...

Acyltransferases are key contributors to triacylglycerol (TAG) synthesis and thus of great importance for seed oil quality. The effect of increased or decreased expression of acyl-CoA:diacylglycerol acyltransferase 1 (DGAT1) or phospholipid:diacylglycerol acyltransferase (PDAT) on seed lipid compositions were assessed in several Camelina sativa lines. Further, in-vitro assays of acyltransferases in microsomal fractions prepared from developing seeds of some of these lines were performed. Decreased expression of DGAT1 led to increased percentage of 18:3n-3 without any change in total lipid content of the seed...

AIMS: Mitochondrial disease (MD) is a genetic disorder affecting skeletal muscles, with possible myocardial disease. The ergoreflex, sensitive to skeletal muscle work, regulates ventilatory and autonomic responses to exercise. We hypothesized the presence of an increased ergoreflex sensitivity in MD patients, its association with abnormal ventilatory and autonomic responses, and possibly with subclinical cardiac involvement. METHODS AND RESULTS: Twenty-five MD patients (aged 46 ± 3 years, 32% male) with skeletal myopathy but without known cardiac disease, underwent a thorough evaluation including BNPs, galectin-3, soluble suppression of tumorigenesis 2 (sST2), high sensitivity troponin T/I, catecholamines, ECG, 24-h ECG recording, cardiopulmonary exercise testing, echocardiography, cardiac/muscle magnetic resonance (C/MMR), and ergoreflex assessment...

Mechanical systems can display topological characteristics similar to that of topological insulators. Here we report a large class of topological mechanical systems related to the BDI symmetry class. These are self-assembled chains of rigid bodies with an inversion centre and no reflection planes. The particle-hole symmetry characteristic to the BDI symmetry class stems from the distinct behaviour of the translational and rotational degrees of freedom under inversion. This and other generic properties led us to the remarkable conclusion that, by adjusting the gyration radius of the bodies, one can always simultaneously open a gap in the phonon spectrum, lock-in all the characteristic symmetries and generate a non-trivial topological invariant...

MicroRNAs are endogenous non-coding small RNAs playing crucial regulatory roles in plants. Tea, a globally popular non-alcoholic drink, is rich in health-enhancing catechins. In this study, 69 conserved and 47 novel miRNAs targeting 644 genes were identified by high-throughout sequencing. Predicted target genes of miRNAs were mainly involved in plant growth, signal transduction, morphogenesis and defense. To further identify targets of tea miRNAs, degradome sequencing and RNA ligase-mediated rapid amplification of 5'cDNA ends (RLM-RACE) were applied...

Tea (Camellia sinensis) is an important commercial crop, in which the high content of flavonoids provides the health benefits. A flavonoid glycosyltransferase (CsUGT73A20), belonged to Cluster IIIa was isolated from tea plant. The recombinant CsUGT73A20 in E. coli exhibited a broad substrate tolerance towards multiple flavonoids. Among them, kaempferol was the optimal substrate compared to quercetin, myricetin, naringenin, apigenin and kaempferide. However, no product was detected when UDP-galactose was used as the sugar donor...

Camellia japonica produces different color and bigger flowers, widely being used for gardening green in southern China. However, cultivars were introduced from different regions, but their origin and pedigree information is either not available poorly documented, causing problems in authentication. Many low-yield trees in Camellia oleifera forests have been used as stocks for grafting C. japonica. However, the survival rate of grafts between these two species is related to genetic relationship between stock of C...

Volatile terpenoids play important roles in the formation of tea aroma quality due to their pleasant scents and low odor thresholds. Most volatile terpenoids contain stereogenic centers, which results in various stereo distributions of their enantiomers and diastereoisomers in different types of tea. However, the distribution characteristics of terpenoid enantiomers in teas were still unclear, which poses an obstacle to the scientific understanding of tea aroma. In this work, a new and efficient analysis approach based on headspace solid phase microextraction (HS-SPME)-chiral gas chromatography-mass spectrometry (GC-MS) was established to analyze 12 pairs of familiar terpenoid enantiomers in different teas...
