Background: Low density lipoprotein (LDL) of egg yolk has been successfully used for stallion and bull semen cryopreservation. However, there is limited information to clarify the effect of LDL or lyophilized LDL on ram semen quality. On the other hand, during semen collection, dilution and cryopreservation we need to protect the spermatozoa from lipid peroxidation. Clove bud has polyphenolic c...

BACKGROUND A positive correlation between an individual's cholesterol level and development of CHD has been suggested. Low levels of high-density lipoprotein cholesterol (HDL-C) and high levels of low-density lipoprotein cholesterol (LDL-C) are important risk factors and oxidation of LDL has been implicated as an initiator of atherosclerosis. AIM Attempts are being made worldwide for the sear...

In 1987 a collaborative study was initiated with 140 laboratories worldwide to evaluate the effects of analytical method and lyophilization on the measurement of different concentrations of apolipoproteins (apo) A-I and B in four lyophilized serum pool samples. This survey confirmed that the lyophilized apo Reference Material of the International Union of Immunological Societies (IUIS) is usefu...

infrequent cases of ethylene glycol poisoning. We believe that glycolic acid measurements can be useful as a supplement, but not as a substitute, to serum ethylene glycol determination, although in most cases the latter will be sufficient. Furthermore, serum ethylene glycol determined enzymatically should be confirmed by another method such as gas chromatography–mass spectrometry (6). However, ...

Background: “Chouriço Vinha d’Alhos” is a traditional fermented dry meat sausage from North of Portugal. The aim of this work was to evaluate the effects of a fresh and a lyophilized bioprotective Lactobacillus plantarum ST153Ch culture, on an industrial scale, on the physicochemical, microbiological, and sensorial characteristics of “Chouriço Vinha d’Alhos”. Methods: “Chouriço Vinha d’Alhos” ...

PURPOSE To evaluate whether lyophilized human platelet lysate (HPL) powder can preserve the growth factor concentrations and epitheliotrophic properties of liquid HPL, and potentially be used as a clinically-friendly treatment option. METHODS Two commercialized liquid HPLs, UltraGRO TM (Helios, Atlanta, GA) and PLTMax (Mill Creek, Rochester, MI), were obtained and converted to lyophilized pow...

different classes of autoantibodies against two antigenic forms of modified low density lipoprotein (mod-ldl) were detected in 140 patients by indirect elisa method. investigated autoantibodes included total immunoglobulins (igt). immunoglobulin g (igg), and immunoglobulin m (igm) against oxidized ldl with copper ions (ox-ldl) and modified ldl with malondialdehyde (mal-ldl) (igt-o) igt against ...

The medicinal Malaysian leeches have been used in traditional medicine to treat many different ailments. In this study, leech saliva extract (LSE) was collected from the medicinal Malaysian leech Hirudinaria manillensis. Gel electrophoresis of LSE was carried out to estimate the peptide and protein molecular weights of its content. Results showed that LSE contains more than 60 peptides and prot...
