Long-Term Fire Regime Modifies Carbon and Nutrient Dynamics in Decomposing Eucalyptus pilularis Leaf Litter
The changes in fire regimes expected under climate change are likely to disrupt the biogeochemical cycling of carbon (C) and nutrients in forest ecosystems. Plant litter decomposition is a critical step in the terrestrial biogeochemical cycle, and is an important determinant of fire fuel load and…

Modulation of extracellular glutamate concentration in rat brain slices by cystine-glutamate exchange
1. The role of cystine-glutamate exchange in controlling the extracellular glutamate concentration in the central nervous system was examined by whole-cell clamping neurons in rat brain slices, and using their glutamate receptors as sensors of extracellular glutamate concentration. 2. Applying…

Stoichiometry of the Glial Glutamate Transporter GLT-1 Expressed Inducibly in a Chinese Hamster Ovary Cell Line Selected for Low Endogenous Na(+)-Dependent Glutamate Uptake
Glutamate transport across the plasma membrane of neurons and glia is powered by the transmembrane electrochemical gradients for sodium, potassium, and pH, but there is controversy over the number of Na(+) cotransported with glutamate. The stoichiometry of glutamate transporters is important…

Mechanical loading effect to the functional bone adaptation
The loads on skeleton control bone turnover, rates of adapted remodeling and influence growth. Mechanical stimulus detected by osteocytes, is derived from muscle contraction or gravity forces. It is difficult to separate the effect of gravity from muscle contractions at bone mass. A great number of…

Do Soil Chemical Changes Contribute to the Dominance of Blady Grass (Imperata cylindrica) in Surface Fire-Affected Forests?
Imperata cylindrica is a perennial grass that often proliferates in fire-affected forests. Recent fire events have been consistently associated with a lowering of soil nitrogen (N) to phosphorus (P) ratios. Thus, I. cylindrica might have a tendency toward P-limited growth and/or tolerance for low…

Rectothecal fistula complicating anterior sacral meningocele repair
We present a case of an iatrogenic rectothecal fistula in a 34-year-old man who underwent repair of a congenital anterior sacral meningocele, intraoperatively complicated by rectal perforation. Postoperatively, the patient developed symptoms of meningitis prompting concern for the cerebrospinal…

Ovarian Torsion in a Teenage Girl with Genitourinary Anomaly
We present the clinical presentation, sonography, CT, and MR imaging as well as correlative intra-operative and gross pathological findings of ovarian torsion in a 14-year-old girl. Our findings are discussed in the context of prior imaging studies performed for the evaluation of ovarian torsion…

Community composition and physiological plasticity control microbial carbon storage across natural and experimental soil fertility gradients
Many microorganisms synthesise carbon (C)-rich compounds under resource deprivation. Such compounds likely serve as intracellular C-storage pools that sustain the activities of microorganisms growing on stoichiometrically imbalanced substrates, making them potentially vital to the function of…

Decline in diversity of tropical soil fauna under experimental warming
Climate change is exacerbating a global decline in biodiversity. Numerous observational studies link rising temperatures to declining biological abundance, richness and diversity in terrestrial ecosystems, yet few studies have considered the highly diverse and functionally significant communities…

Limitations and artifacts in shear-wave elastography of the liver
Recent studies have shown that real-time, two-dimensional shear-wave elastography (2D-SWE) can monitor liver fibrosis by measuring tissue elasticity (i.e., elastic modulus). Two clinical studies of 2D-SWE in the liver have shown that there are several practical issues that can compromise…

Bewegungsanalyse bei Querschnittverletzungen
For motor incomplete spinal cord injured patients, improvement of walking function is an important aim in the rehabilitation program. In specialized treatment centers, the 6‑minute walking test, the 10-meter walking test or the timed-up-and-go test are used as an assessment tool to determine…

Arthropod abundances track soil fertility across a lowland tropical forest landscape
1. Soil phosphorus (P) drives productivity and floristic composition across tropical forest landscapes, but equivalent links between soil P and tropical forest fauna remain poorly understood. 2. We evaluated soil P as a driver of understorey Coleoptera and epigeal arthropod assemblages across a…

Charcot spinal arthropathy: an increasing long-term sequel after spinal cord injury with no straightforward management
Charcot spinal arthropathy (CSA) is most likely increasing in patients suffering from consequences of spinal cord injury. We want to highlight initial symptoms, certain risk factors and perioperative complications of this condition. A single center retrospective case series in a specialized Center…

An MRI-guided HIFU-triggered wax-coated capsule for supertargeted drug release: a proof-of-concept study
BACKGROUND: Externally controlling and monitoring drug release at a desired time and location is currently lacking in the gastrointestinal tract. The aim of the study was to develop a thermoresponsive wax-coated capsule and to trigger its release upon applying a magnetic resonance imaging…
