Chasing the perfida Albione: Anglo‐Italian productivity gap in the late 1930s

The Economic History Review, EarlyView.
Abstract This paper presents new estimates of Anglo‐Italian labour productivity levels in manufacturing in the late 1930s, derived using the standard single‐deflation approach. The findings confirm a substantial productivity gap between Italy and the United Kingdom at the aggregate level, alongside pronounced intersectoral heterogeneity.

Pilus distribution among lineages of group b streptococcus: an evolutionary and clinical perspective [PDF]

, 2014
<b>Background</b><p></p> Group B Streptococcus (GBS) is an opportunistic pathogen in both humans and bovines. Epidemiological and phylogenetic analyses have found strains belonging to certain phylogenetic lineages to be more ...

Type IV-Like Pili Facilitate Transformation in Naturally Competent Archaea

Journal of Bacteriology, 2020
Microbial organisms adapt and evolve by acquiring new genetic material through horizontal gene transfer. One way that this occurs is natural transformation, the direct uptake and genomic incorporation of environmental DNA by competent organisms. Archaea represent up to a third of the biodiversity on Earth, yet little is known about transformation in ...

Water, water, every where—the advent of hydrated pili structure

The FEBS Journal, EarlyView.
Protein structure is defined by its surrounding water. Naturally, this is also true for the gigantic protein filaments that pathogenic bacteria use to attach to and colonize their host cells. Structures of these filaments for which water can be identified with high confidence have stayed elusive for the longest time.

Predation by Bdellovibrio bacteriovorus HD100 Requires Type IV Pili [PDF]

Journal of Bacteriology, 2007
ABSTRACT Early electron microscopy and more recent studies in our laboratory of Bdellovibrio bacteriovorus cells indicated the presence of narrow fibers at the nonflagellar pole of this unusual predatory bacterium. Analysis of the B.

Adhesion of Neisseria meningitidis to dermal vessels leads to local vascular damage and purpura in a humanized mouse model.

PLoS Pathogens, 2013
Septic shock caused by Neisseria meningitidis is typically rapidly evolving and often fatal despite antibiotic therapy. Further understanding of the mechanisms underlying the disease is necessary to reduce fatality rates.

The Keystone‐Pathogen Hypothesis Updated: The Role of Porphyromonas gingivalis in Periodontitis

Journal of Periodontal Research, EarlyView.
Porphyromonas gingivalis orchestrates a coordinated manipulation of immune and inflammatory responses in periodontal tissues which leads to the generation of a dysbiotic, subgingival biofilm community, and progression of periodontitis. The type 9 secretion system, lipid A modification, and the formation of outer membrane vesicles are important ...

Controlled trial of lovastatin combined with an open-label treatment of a parent-implemented language intervention in youth with fragile X syndrome. [PDF]

, 2020
BackgroundThe purpose of this study was to conduct a 20-week controlled trial of lovastatin (10 to 40 mg/day) in youth with fragile X syndrome (FXS) ages 10 to 17 years, combined with an open-label treatment of a parent-implemented language intervention (

Direct observation of extension and retraction of type IV pili [PDF]

Proceedings of the National Academy of Sciences, 2001
Type IV pili are thin filaments that extend from the poles of a diverse group of bacteria, enabling them to move at speeds of a few tenths of a micrometer per second. They are required for twitching motility, e.g., in Pseudomonas aeruginosa and Neisseria gonorrhoeae , and for social ...

Circular RNAs in Lotus japonicus Responses to Nutrient Supply and Mesorhizobium Symbiosis

Plant, Cell &Environment, EarlyView.
ABSTRACT Symbiotic interactions between legumes and rhizobia enable nitrogen fixation under low nutrient conditions. The establishment and function of symbiotic interactions require coordinated changes in gene expression in both the host and the microbe. Circular RNAs (circRNAs) are endogenous gene‐specific molecules that can regulate transcription and
