This study aimed to improve the quality of cryopreserved goat semen for artificial insemination by the addition of cattle seminal plasma crude protein. Semen collected from cattle and centrifuged to obtain seminal plasma. Then it was purified to obtain the crude protein. The diluent used in this study was milk-yolk. There were three groups, control group without crude protein (P0), the addition...

This study evaluates the hypothesis that ethanol alone, or in diluents for drugs used to protect hypoxic mice, is responsible in part for an increased tolerance to hypoxia (4-5% oxygen). The change in hypoxic tolerance following i.v. or i.p. administration of ethanol, diazepam, nimodipine and various diluent components was measured. Diazepam (50 mg/kg i.v.) increased hypoxic tolerance to 700 +/...

semen collection evaluation and addition of preservatives to increase storage period of sperm are essential for successful artificial insemination. this study was conducted on 4rams (2 ghezel merinos and 2 merinos moghani) to evaluate the effect of two diluents in khalatposhan research station. average age of rams was 3 years. rams were trained to serve the artificial insemination and semen sam...

The aim of this investigation was to develop a novel multifunctional co-processed diluent consisting of microcrystalline cellulose (Avicel PH 102), crospovidone (Polyplasdone XL) and polyethylene glycol 4000. Colloidal silicon dioxide and talc were also incorporated as minor components in the diluent to improve tableting properties. Melt granulation was adopted for preparation of co-processed d...

The fact that the choice of organic diluent is important for a solvent extraction process goes without saying. Several factors, such as e.g. price, flash point, viscosity, polarity etc. each have their place in the planning of a solvent extraction system. This high number of variables makes the lack of compilations concerning diluent effects to an interesting topic. Often the interest for the r...

The following substances were added to a basic diluent for fowl semen either separately or in combination: caproic acid, formaldehyde, acetyl carnitine, adenine, inosine, sodium pyruvate, succinic acid, dithiothreitol, sodium citrate and zinc, chloride, bicarbonate and phosphate. No significant improvement in the fertility of semen stored at 5 degrees C for either 24 or 48 hrs was obtained over...

The effects of the in ovo injection of commercial diluent containing various levels of 25-hydroxycholecalciferol [25(OH)D3] on hatchability and hatching chick quality variables in Ross × Ross 708 broilers were examined in 2 trials. All treatment groups, each containing 21 and 40 eggs in trials 1 and 2, respectively, were randomly represented on each of 10 replicate tray levels of a single-stage...

Objectives: N2O is widely used in the chemical industry and laboratories; however, several fire/explosion accidents have been reported facilities that handle N2O. This study aimed (i) to experimentally investigate lower upper flammability limits (LFL UFL, respectively), limit nitrous oxide concentration (LN2OC), minimum inerting concentrations (MICs) of fuel–N2O–diluent mixtures (ii) computatio...

The effect of nanoconfinement on the glass transition temperature T(g) in thin polymer films is studied as a function of added small-molecule diluent or plasticizer. The decrease [increase] in T(g) found in nanoconfined, neat polystyrene [poly(2-vinyl pyridine)] is suppressed by added diluent, with 13-20 nm thick polystyrene films exhibiting bulk T(g) upon addition of 9 wt % pyrene or 4 wt % di...

We describe a simple system for the preparation of a hyperlipidemic control serum. Beta- and pre-beta-lipoproteins are removed from the serum and prepared as a stable diluent; the extracted serum is then lyophilized. Upon addition of the lipoprotein diluent, which was observed to contain only liproprotein and sodium bicarbonate, the serum reconstitutes rapidly, usually within 5 min. By a suitab...
