Po protein, the dominant protein in peripheral nervous system myelin, was studied immunocytochemically in both developing and mature Schwann cells. Trigeminal and sciatic nerves from newborn, 7-d, and adult rats were processed for transmission electron microscopy . Alternating 1-lam-thick Epon sections were stained with paraphenylenediamine (PD) or with Po antiserum according to the peroxidase-...

BACKGROUND Although matrix metalloproteinases (MMPs) were initially thought to result primarily in extracellular matrix degradation, certain MMP types, such as membrane type-1 (MT1) MMP, may also be involved in profibrotic cascades through hydrolysis of latency-associated transforming growth factor-binding protein (LTBP-1) and activation of transforming growth factor-dependent profibrotic signa...

In 15 spontaneously breathing patients with chronic obstructive pulmonary disease (COPD) divided into two groups, one with normocapnia (A) and one with chronic hypercapnia (B), we evaluated the maximal voluntary inspiratory muscle strength (MIP), the pattern of breathing, the mouth occlusion pressure (Po.1), the neural respiratory drive (NRD), assessed by surface electromyographic (EMG) activit...

The spectra of both protons and alph'a pa•-ticles (1 <• E • 7 MeV/nucleon) during 31 recurrent particle streams are fit well by an exponential in particle rigidity. Although the spectra show considerable temporal variation, the proton and alpha particle spectra are correlated such that the e-folding rigidities Po(•) and Po(P) of the two spectra are in the ratio Po(•)/ Po(P) = 1.5 ñ 0.1. The con...

[1] Due to its high volatility, Po can be effectively released from active volcanoes prior to their explosions. A continuous record of the fallout rate of Po versus that of Pb in northern Taiwan reveals that most of the Po was derived from preeruption gas emission of Philippines’Mayon volcano in the past two years. From this observation we suggest that, if a global network can be properly desig...

It is important to seek out plant species, high in phosphorus (P) uptake, for phytoremediation of P-enriched environments with a large amount of organic P (Po). P assimilation characteristics and the related mechanisms of Polygonum hydropiper were investigated in hydroponic media containing various concentrations of Po (1-8 mmol L(-1)) supplied as phytate. The mining ecotype (ME) showed signifi...

The increasing volume and complexity of waste associated with the modern economy poses a serious risk to ecosystems and human health. However, the remanufacturing and recycling of waste into usable products can lead to substantial resource savings. In the present study, clam shell waste was first transformed into pure and well-crystallized single-phase white light-emitting phosphor Ca₉Gd(PO₄)₇:...

Satellite cell activity is necessary for postnatal skeletal muscle growth. Severe phosphate (PO(4)) deficiency can alter satellite cell activity, however the role of neonatal PO(4) nutrition on satellite cell biology remains obscure. Twenty-one piglets (1 day of age, 1.8 ± 0.2 kg BW) were pair-fed liquid diets that were either PO(4) adequate (0.9% total P), supra-adequate (1.2% total P) in PO(4...
