High-Volume Culture Improves Diagnostic Yield of Aspergillus Species From Sputum. [PDF]

Mycoses
ABSTRACT Objectives Sputum is a commonly collected specimen for suspected respiratory fungal infections due to its non‐invasive nature and diagnostic value. However, conventional culture at 29°C (CC29) often fails to detect filamentous moulds. To improve recovery, we applied a high‐volume culture incubated at 37°C (HVC37) and compared its diagnostic ...

Proximal tubular dysfunction associated with tenofovir in an HVC-HIV co-infected patient undergoing HVC therapy [PDF]

Clinical Kidney Journal, 2008
Sir, Tenofovir is an adenosine analogue, and exposure to ribavirin (RBV) could increase the intracellular phosphorylated metabolities of tenofovir. Nucleoside analogues essentially have mitochondrial toxicity. Nephrotoxicity of these nucleoside analogues in combination with HVC therapy is a rare complication [1].

Activity in a premotor cortical nucleus of zebra finches is locally organized and exhibits auditory selectivity in neurons but not in glia. [PDF]

PLoS ONE, 2013
Motor functions are often guided by sensory experience, most convincingly illustrated by complex learned behaviors. Key to sensory guidance in motor areas may be the structural and functional organization of sensory inputs and their evoked responses.

The Gene Expression Profile of the Song Control Nucleus HVC Shows Sex Specificity, Hormone Responsiveness, and Species Specificity Among Songbirds

Frontiers in Neuroscience, 2021
Singing occurs in songbirds of both sexes, but some species show typical degrees of sex-specific performance. We studied the transcriptional sex differences in the HVC, a brain nucleus critical for song pattern generation, of the forest weaver (Ploceus ...

Seasonal changes in patterns of gene expression in avian song control brain regions.

PLoS ONE, 2012
Photoperiod and hormonal cues drive dramatic seasonal changes in structure and function of the avian song control system. Little is known, however, about the patterns of gene expression associated with seasonal changes.

Cooperation of deterministic dynamics and random noise in production of complex syntactical avian song sequences: a neural network model

Frontiers in Computational Neuroscience, 2011
How the brain learns and generates temporal sequences is a fundamental issue in neuroscience. The production of birdsongs, a process which involves complex learned sequences, provides researchers with an excellent biological model for this topic.

Acetylcholine acts on songbird premotor circuitry to invigorate vocal output

eLife, 2020
Acetylcholine is well-understood to enhance cortical sensory responses and perceptual sensitivity in aroused or attentive states. Yet little is known about cholinergic influences on motor cortical regions.

Surgical Results in One-level Vertebroplasty for Osteoporotic Vertebral Fracture in Thoracic or Lumbar Spine: Radiographic Comparison between Low-viscosity Cement and High-viscosity Cement

Formosan Journal of Musculoskeletal Disorders, 2023
Background: Percutaneous vertebroplasty (PVP) is a highly effective procedure for managing painful osteoporotic vertebral fractures (VFs). Objectives: The objective of this retrospective study was to compare the surgical outcomes of patients treated with

Local field potentials in a pre-motor region predict learned vocal sequences.

PLoS Computational Biology, 2021
Neuronal activity within the premotor region HVC is tightly synchronized to, and crucial for, the articulate production of learned song in birds. Characterizations of this neural activity detail patterns of sequential bursting in small, carefully ...
