BACKGROUND The pathological classification of cryptogenic fibrosing alveolitis has been a matter of debate and controversy for histopathologists. OBJECTIVE To identify and specify the glycotypes of capillary endothelial cells in usual interstitial pneumonia (UIP) compared to those found in normal tissue. METHODS Sections of formalin-fixed, paraffin-embedded blocks from 16 cases of UIP were ...

For some polyphagous insects, adaptation to phytochemically novel plants can enhance resistance to certain pesticides, but whether pesticide resistance expands tolerance to phytochemicals has not been examined. Amyelois transitella Walker (navel orangeworm) is an important polyphagous pest of nut and fruit tree crops in California. Bifenthrin resistance, partially attributable to enhanced cytoc...

Phylogenetic relationships in the tribe Millettieae and allies in the subfamily Papilionoideae (Leguminosae) were reconstructed from chloroplast trnK/matK sequences. Sixty-two accessions representing 57 traditionally recognized genera of Papilionoideae were sampled, including 27 samples from Millettieae. Phylogenies were constructed using maximum parsimony and are well resolved and supported by...

Hyaluronan is a linear glycosaminoglycan that forms the backbone of perineuronal nets around neurons in the cerebral cortex. However, it remains controversial whether neurons are capable of independent hyaluronan synthesis. Herein, we examined the expression of hyaluronan and hyaluronan synthases (HASs) throughout cortical neuron development in vitro. Enriched cultures of cortical neurons were ...

Perineuronal nets (PNs) are aggregates of extracellular matrix that have been associated with neuronal plasticity, critical periods, fast-spiking cells and protection from oxidative stress. Although PNs have been reported in the auditory system in several species, there is disagreement about the distribution of PNs within the inferior colliculus (IC), an important auditory hub in the midbrain. ...

Perineuronal nets (PNs) are a specialized form of extracellular matrix, surrounding different types of neurons and mainly consist of chondroitin sulfate proteoglycans connected to hyaluronan, stabilized by link protein and cross-linked via tenascin-R. Due to their polyanionic character, caused by the highly charged chondroitin sulfate glycosaminoglycan and hyaluronan components, PNs might be in...

Metabolized by liver sinusoidal endothelial cells, autotaxin (ATX) is a secreted enzyme considered to be associated with liver damage. We sought to clarify the diagnostic ability of ATX for liver fibrosis in 593 biopsy-confirmed hepatitis C virus (HCV)-infected patients. The diagnostic accuracy of ATX was compared with clinical parameters and the established fibrosis biomarkers Wisteria floribu...
