With an aim to elucidate the significance of Human Placental Lactogen (HPL) during gestation, I assayed the HPL and HCG concentration in the chorionic tissue and the blood. The results as follows: 1) There was a definite correlation between the HPL concentration in the maternal serum at term and the weight of the neonates, which might lead to an idea that HPL took part in the growth of fetuses ...

The results of studies with cultured endothelial cells have shown that most von Willebrand factor (vWF) synthesized is directly secreted (constitutive pathway) and consists of both mature vWF, its precursor molecule pro-vWF, and the cleaved vWF prosequence. Only fully processed, functionally mature vWF is stored within the cell, together with the propeptide, and leaves the cell only on stimulat...

Precise measurements on the density of sodium polystyrenesulphonate solutions in methanol-water mixed solvent media containing 8, 16, and 25 weight per cent of methanol at 308.15, 318.15, and 323.15 K are reported. The degree of substitution of sodium polystyrenesulphonate used is 1, and the concentrations are varied from 1 ×10 to 3.8 ×10 monomol.l. The results showed a slight increase on the p...

The development and design of the biocompatible and biodegradable thermodynamically stable micellar and microemulsion transparent dispersions to reduce the free and unbounded drugs concentration in the blood is a basic challenge in field of drug efficacy and bioavailability of drugs. In the current work, solubilization capacity of the drug (Tocopherol), oil (Ethyl Butyrate), and oil+drug (1:1 m...

copolymerization of ethylene and propylene was investigated using a 4th generation phthalate ziegler-natta catalyst in normal hexane in a buchi reactor. the effects of different mole fractions of [al]/[ti], [si]/[al] and various amounts of hydrogen on productivity and weight percent of ethylene on the product, were studied. in the copolymerization reactions, tri-isobutyl aluminum (tibal) was us...

Both the continuous and batch transesterification of linseed oil were examined in order to maximize the fatty acid methyl esters (FAME) yield. The continuous process was conducted in a packed bed reactor using calcium oxide as a heterogeneous catalyst. In addition, the impact of two variables, namely the molar ratio of methanol to oil and the flow rate (ml/min), on the FAME yield were stu...

Molar concentration of sodium chloride partially stabilized feline calicivirus against thermal inactivation at 50 C. One strain of feline calicivirus was relatively acid labile compared to another.

Application of the principle of critical-point universality to various phase transitions in fluid mixtures, also known as “isomorphism hypothesis”, is based on analytic relations between theoretical scaling fields (“ordering” and “thermal”) and physical fields, such as chemical potentials and temperature [1]. As a result, the universal Ising-model order parameter appears to be a combination of ...

Pravastatin (PRAV) is a hydrophilic statin which has been reported to have antiangiogenic and pro-apoptotic effects. However, the beneficial effects of statins on tumour growth are obtained at high doses, the systemic administration of those doses being associated with severe toxicity. Thus, site-specific delivery with liposomal systems may be a novel approach in order to enrich its therapeutic...

introdouction: impacted mandibular third molar surgery may affect periodontal status of the adjacent second molar. the purpose of this study was to evaluate the changes in periodontal health parameters distal to the adjacent second molar following surgical extraction of an impacted mandibular third molar. materials and methods: we selected 50 subjects with a mean age of 22.8 (ranging from 18 to...
