Cyclotides are a family of triple disulfide cyclic peptides with exceptional resistance to thermal/chemical denaturation and enzymatic degradation. Several cyclotides have been shown to possess anti-HIV activity, including kalata B1 (KB1). However, the use of cyclotides as anti-HIV therapies remains limited due to the high toxicity in normal cells. Therefore, grafting anti-HIV epitopes onto a c...

Degenerate primers were used to amplify 14 distinct reductive-dehalogenase-homologous (RDH) genes from the Dehalococcoides-containing mixed culture KB1. Most of the corresponding predicted proteins were highly similar (97 to >99% amino acid identity) to previously reported Dehalococcoides reductive dehalogenases. To examine the differential transcription of these RDH genes, KB1 was split into f...

Eighty computer users with musculoskeletal disorders participated in a 6-month, randomized, placebo-controlled trial evaluating the effects of four computer keyboards on clinical findings, pain severity, functional hand status, and comfort. The alternative geometry keyboards tested were: the Apple Adjustable Keyboard [kb1], Comfort Keyboard System [kb2], Microsoft Natural Keyboard [kb3], and pl...

Background: We have demonstrated previously that NFKB1 single nucleotide polymorphism (SNP) rs4648068 GG homozygote was associated with an increased risk of gastric cancer in the Chinese Han population. In this study, we constructed the recombinant plasmid pGL3-GG and pGL3-AA and investigated the function of rs4648068 by cell biology experiments. Methods: Quantitative real-time PCR was used to ...

ITALIC! Bacillus thuringiensisis the most widely known microbial pesticide used in agricultural applications. Herein, we report a draft genome sequence of the endophytic bacterium ITALIC! Bacillus thuringiensisstrain KB1, which exhibits antagonism against phytopathogens.

Two reciprocal interspecies hybrid class I histocompatibility genes have been constructed between genomic clones of human HLA-A2 and murine H-2Kb. The proteins encoded by these genes have been designated A21+2/Kb, where the polymorphic domains, alpha 1 and alpha 2, of HLA-A2 are linked to the carboxyl-terminal domains (alpha 3, transmembrane, and intracytoplasmic domains) of H-2Kb, and Kb1+2/A2...

Cell-mediated and humoral immune status of free-ranging green turtles (Chelonia mydas) in Hawaii (USA) with and without fibropapillornatosis (FP) were assessed. Tumored and non-tumored turtles from Kaneohe Bay (KB) on the island of Oahu and from FP-free areas on the west (Kona/Kohala) coast of the island of Hawaii were sampled from April 1998 through February 1999. Turtles on Oahu were grouped ...

Chicken feathers are major poultry waste that is difficult to process in its native form due highly resistant keratin protein large amounts. In this study, a novel feather-degrading bacterium, Bacillus amyloliquefaciens KB1, was screened from chicken farm bed (CFB) using morphological and biochemical tests followed by 16s rDNA analysis. Among observed isolates, bacterial isolate (KB1) showed th...
