HrgS (Avin_34990), a novel histidine-kinase related to GacS, regulates alginate synthesis in Azotobacter vinelandii.

Azotobacter vinelandii is a soil bacterium that produces alginates, a family of polymers of biotechnological interest. In A. vinelandii, alginate production is controlled by the two-component system GacS/GacA.

Anatomical variations of the acromial and coracoid process: clinical relevance.

Purpose: The acromial and coracoid process morphology is of clinical relevance due to associations with functional limitations and shoulder pathology. Our objective was to describe the anatomical characteristics of the acromial and coracoid process using computed tomography (CT).

Methods: Descriptive, observational, transversal and retrospective study.

Outcomes of an enhanced recovery after radical cystectomy program in a prospective multicenter study: compliance and key components for success.

Objective: To investigate the effect of an Enhanced Recovery After Surgery (ERAS) program on complications and length of stay (LOS) after radical cystectomy (RC) and to assess if the number and type of components of ERAS play a key role on the decrease of surgical morbidity.

Materials And Methods: We analyzed the data of 277 patients prospectively recruited in 11 hospitals undergoing RC initially managed according to local practice (Group I) and later within an ERAS program (Group II). Two main outcomes were defined: 90-day complications rate and LOS.

Morphologic changes of the fifth phalange secondary to smartphone use.

Background: The use of smart phones is now part of the daily routine throughout the world. Morphological alterations have been described associated with telephone holding technique, as well as clinically significant alterations related to their use.

Objective: The objective was to determine the macroscopic morphological changes due to smartphone use in the fifth finger of the hand with which the smartphone is commonly used.

Identification of a N-acyl Homoserine Lactone Type Quorum Sensing System and a New LysR-type Transcriptional Regulator Associated with Antimicrobial Activity and Swarming in UAPS07070.

A random transposition mutant library of UAPS07070 was analyzed for searching mutants with impaired microbial antagonism. Three derivates showed diminished antimicrobial activity against a sensitive strain. The mutated loci showed high similarity to the quorum sensing genes of the AHL-synthase and its regulator.
