PURPOSE To explore the possibility of the PEGylated liposome-protamine-hyaluronic acid nanoparticles (PEG-LPH-NP) loaded with siRNA (PEG-LPH-NP-S) in ARPE19 cells and a laser-induced rat model for the treatment of choroidal neovascularization (CNV). METHODS PEG-LPH-NP-S was characterized by dynamic light scattering and transmission electron microscopy (TEM). The encapsulation efficiency of si...

The effect of glycosylation on the intracellular transport of human intestinal lactase-phlorizin hydrolase (LPH) was investigated by biosynthetic labeling of biopsy samples in the presence or absence of glycosidase inhibitors. In the presence of deoxynojirimycin (dNM) and deoxymannojirimycin (dMM), endo H sensitive LPH glycoforms of M(r) = 135,000 in both cases were produced (LPHdNM and LPHdMM)...

We have estimated the synthesis rates in vivo of precursor and brush-border (BB) polypeptides of lactase phlorhizin hydrolase (LPH) in newborn pigs fed with water or colostrum for 24h post partum. At the end of the feeding period, piglets were anaesthetized and infused intravenously for 3h with L-[4-3H]- phenylalanine. Blood and jejunal samples were collected at timed intervals. The precursor a...

This papers addresses whether observed violations in the Liquidity Preference Hypothesis (LPH) can be explained by the presence of multiple regimes in the term premia. The investigation proceeds by directly testing the LPH via a series of inequality tests which allow the moments to be conditioned on observable information using an instrumental variables approach. The apparent rejection of the L...

We have previously shown that dietary sucrose stimulates the lactase/phlorizin hydrolase (LPH) mRNA accumulation along with a rise in lactase activity in rat jejunum [Goda, Yasutake, Suzuki, Takase and Koldovský (1995) Am. J. Physiol. 268, G1066-G1073]. To elucidate the mechanisms whereby dietary carbohydrates enhance the LPH mRNA expression, 7-week-old rats that had been fed a low-carbohydrate...

We have previously identified and purified a novel beta-glucosidase, designated PNGH (pyridoxine-5'-beta-D-glucoside hydrolase), from the cytosolic fraction of pig intestinal mucosal. PNGH catalyses the hydrolysis of PNG (pyridoxine-5'-beta-D-glucoside), a plant derivative of vitamin B6 that exhibits partial nutritional bioavailability in humans and animals. Preliminary amino acid sequence anal...

Lactase-phlorizin hydrolase (LPH) is a membrane bound intestinal hydrolase, with an extracellular domain comprising 4 homologous regions. LPH is synthesized as a large polypeptide precursor, pro-LPH, that undergoes several intra- and extracellular proteolytic steps to generate the final brush-border membrane form LPHbeta(final). Pro-LPH is associated through homologous domain IV with the membra...

The attachment of polyethylene glycol (PEG) increases the circulation time of drug-containing nanoparticles; however, this also negatively affects cellular uptake. To overcome this problem, unique lipid polymer hybrid (LPH) nanoparticles were developed with a pH-responsive PEG layer that detached prior to cell uptake. Docetaxel (DTX) was incorporated into the lipid core of the nanoparticles, wh...

Lucio's phenomenon (LPh) is considered a necrotizing panvasculitis and a variant of leprosy Type 2 reaction, clinically characterised by necrotic-haemorrhagic lesions on the extremities and trunk. LPh is observed in diffuse lepromatous leprosy (DLL or Lucio-Latapí leprosy). This is a distinct form of lepromatous leprosy (LL) reported mainly in Mexico. Anti-phospholipid antibody syndrome (APS) h...

Adrenocorticotropin and beta-lipotropin (beta-LPH) have been localized by immunoperoxidase methods in nerve cells and fibers of the hypothalamus and brain stem of the ewe. 6-mum sections were immunostained first for either ACTH or beta-LPH. The reaction products and the antibody complexes were then eluted completely from the tissue, and the same section was immunostained for the second peptide....
