A 10-year retrospective review of pediatric lung abscesses from a single center

open access: yesAnnals of Thoracic Medicine, 2016
Introduction: Pediatric lung abscesses can be primary or secondary, and there is limited data regarding response to treatments and patient outcomes. Objectives: To assess the clinical and microbiologic profile of pediatric patients with lung abscess and ...

Collapsing Bacterial Cylinders

open access: yes, 1999
Under special conditions bacteria excrete an attractant and aggregate. The high density regions initially collapse into cylindrical structures, which subsequently destabilize and break up into spherical aggregates.

Estuarine Nitrifiers: New Players, Patterns and Processes [PDF]

open access: yes, 2010
Ever since the first descriptions of ammonia-oxidizing Bacteria by Winogradsky in the late 1800s, the metabolic capability of aerobic ammonia oxidation has been restricted to a phylogenetically narrow group of bacteria.

Adjunctive Therapeutic Plasma Exchange in Refractory Adult‐Onset Still's Disease Complicated by Secondary Macrophage Activation Syndrome: A Single‐Center Experience

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Adult‐onset Still's disease (AOSD) complicated by macrophage activation syndrome (MAS) carries substantial mortality. The role of therapeutic plasma exchange (TPE) remains uncertain. Methods We retrospectively analyzed patients with AOSD‐MAS treated with TPE at a single‐center.

An updated overview on the bacterial PhoP/PhoQ two-component signal transduction system

open access: yesFrontiers in Cellular and Infection Microbiology
The PhoP response regulator and the cognate sensor kinase PhoQ form one of the two-component signal transduction systems that is highly conserved in bacteria. The PhoP/PhoQ system is a crucial mediator of signal transduction.

Mapping the evolution of mitochondrial complex I through structural variation

open access: yesFEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Effects of Grazing in a Low Deciduous Forest on Rumen Microbiota and Volatile Fatty Acid Production in Lambs

open access: yesAnimals
The aim of the present study was to evaluate the effect of grazing the low deciduous forest (LDF) vegetation on the diversity of the rumen microbiome in growing lambs and its relationship with volatile fatty acid (VFA) profiles.

Bacterial rheotaxis [PDF]

open access: yesProceedings of the National Academy of Sciences, 2012
The motility of organisms is often directed in response to environmental stimuli. Rheotaxis is the directed movement resulting from fluid velocity gradients, long studied in fish, aquatic invertebrates, and spermatozoa. Using carefully controlled microfluidic flows, we show that rheotaxis also occurs in bacteria.
