B regulates IS256-mediated Staphylococcus aureus biofilm phenotypic variation
Biofilm formation in Staphylococcus aureus is subject to phase variation, and biofilm-negative derivatives emerge sporadically from a biofilm-positive bacterial population. To date, the only known mechanism for generating ... -
Bacillus thuringiensis Cyt proteins as enablers of activity of Cry and Tpp toxins against Aedes albopictus
Aedes albopictus is a species of mosquito, originally from Southeast Asia, that belongs to the Culicidae family and the Dipteran insect order. The distribution of this vector has rapidly changed over the past decade, making ... -
Bacillus thuringiensis toxins: an overview of their biocidal activity
Bacillus thuringiensis (Bt) is a Gram positive, spore-forming bacterium that synthesizes parasporal crystalline inclusions containing Cry and Cyt proteins, some of which are toxic against a wide range of insect orders, ... -
Back to the future: a sensitivity analysis to predict future fertility rates considering the influence of family policies. The cases of Spain and Norway
This article analyzes the relationship between family policies focused on childcare for children under the age of three and fertility levels. In the current context of very low European fertility, it is important to ... -
Bacmid expression of granulovirus enhancin En3 accumulates in cell soluble fraction to potentiate nucleopolyhedrovirus infection
Enhancins are metalloproteinases that facilitate baculovirus infection in the insect midgut. They are more prevalent in granuloviruses (GVs), constituting up to 5% of the proteins of viral occlusion bodies (OBs). In ... -
Bacterial biofilm functionalization through Bap amyloid engineering
Biofilm engineering has emerged as a controllable way to fabricate living structures with programmable functionalities. The amyloidogenic proteins comprising the biofilms can be engineered to create self-assembling ... -
Baculovirus expression and functional analysis of Vpa2 proteins from Bacillus thuringiensis
The mode of action underlying the insecticidal activity of the Bacillus thuringiensis (Bt) binary pesticidal protein Vpa1/Vpa2 is uncertain. In this study, three recombinant baculoviruses were constructed using Bac-to-Bac ... -
Baculovirus-induced climbing behavior favors intraspecific necrophagy and efficient disease transmission in Spodoptera exigua
Shortly prior to death, many species of Lepidoptera infected with nucleopolyhedrovirus climb upwards on the host plant. This results in improved dissemination of viral occlusion bodies over plant foliage and an increased ... -
Bad company. The indirect effect of differences in corporate governance in the pension plan industry
This paper analyses the role played by pension plan governance structure and how it impacts on plan fees and plan performance. The results clearly show that fees decrease significantly and performance improves when pension ... -
Balance historiográfico y aportaciones científicas del bicentenario de la ocupación napoleónica en Navarra, Aragón, Álava y La Rioja
El Bicentenario de la guerra de la Independencia ha dado pie a una producción científica de gran interés y a varios congresos, jornadas y actividades culturales de diversa índole. Los temas más debatidos en los Congresos ... -
Band-pass filter-like antenna validation in an ultra-wideband in-car wireless channel
Ultra-wideband (UWB) is a very attractive technology for innovative in-car wireless communications requiring high data rates. A designated antenna, which presents a reflection coefficient (S11) matched band comparable to ... -
Bank fragility and contagion: evidence from the bank CDS market
Understanding how contagion works among financial institutions is a top priority for regulators and policy makers who aim to foster financial stability and to prevent financial crises. Using bank credit default swap (CDS) ... -
Banking stability, competition, and economic volatility
The paper analyzes the influence of banking stability on the volatility of industrial value added and how it varies across 110 countries depending on bank market competition and bank-firm relationships. We find that banking ... -
Bap, a biofilm matrix protein of Staphylococcus aureus prevents cellular internalization through binding to GP96 host receptor
The biofilm matrix, composed of exopolysaccharides, proteins, nucleic acids and lipids, plays a well-known role as a defence structure, protecting bacteria from the host immune system and antimicrobial therapy. However, ... -
Bap, a Staphylococcus aureus surface protein involved in biofilm formation
Identification of new genes involved in biofilm formation is needed to understand the molecular basis of strain variation and the pathogenic mechanisms implicated in chronic staphylococcal infections. A biofilm-producing ... -
Los barruntos de Park. Antes de Chicago
Un prefacio introductorio a la traducción al español de un artículo clásico de 1904 por Robert Ezra Park; una investigación metodológica y sociológica. -
Base pairing interaction between 5′- and 3′-UTRs controls icaR mRNA translation in Staphylococcus aureus
The presence of regulatory sequences in the 39 untranslated region (39-UTR) of eukaryotic mRNAs controlling RNA stability and translation efficiency is widely recognized. In contrast, the relevance of 39-UTRs in bacterial ... -
Baseline circulating blood cell counts and ratios and changes therein for predicting immune-related adverse events during immune checkpoint inhibitor therapy: a multicenter, prospective, observational, pan-cancer cohort study with a gender perspective
Several factors have been associated with the occurrence of immune-related adverse events (irAEs) induced by immune checkpoint inhibitor (ICI) therapy. Despite their availability, the predictive value of circulating blood ... -
