introduction: it has been shown that some primary human tumors and their metastases, including prostate and breast tumors, over-express gastrin-releasing peptide (grp) receptors. bombesin is a neuropeptide with a high affinity for these grp receptors. the purpose of this study was to prepare and evaluate the characteristics of a new freeze-dried kit, [6-hydrazinopyridine-3-carboxylic acid (hyni...

BACKGROUND This study aimed to evaluate freeze-dried sera as an alternative to non-freeze dried for detection of anti-Leishmania infantum antibodies over the course of 11 months using the direct agglutination test (DAT). METHODS Altogether, 60 serum samples (30 from humans and 30 from dogs) were collected from various geographical locations in Iran. All the collected sera were pooled and each...

Freeze-dried spermatozoa are capable of participating in normal embryonic development after injection into oocytes and thus useful for the maintenance of genetic materials. We recently reported that long-term preservation of freeze-dried mouse spermatozoa by conventional methods requires temperatures lower than -80 degrees C. Successful permanent preservation of mouse spermatozoa at much higher...

Erythrocytes collected from 1-day-old chicks were stabilized by fixation with formaldehyde and by freeze-drying after treatment with carbon monoxide. Suspensions of freeze-dried erythrocytes in distilled water or physiological saline had a homogeneous bright reddish-purple color. Freeze-dried erythrocytes were compared with fresh erythrocytes for hemagglutination and hemagglutination-inhibition...

Mango processing produces significant amount of waste (peels and kernels) that can be utilized for the production of value-added ingredients for various food applications. Mango peel and kernel were dried using different techniques, such as freeze drying, hot air, vacuum and infrared. Freeze dried mango waste had higher antioxidant properties than those from other techniques. The ORAC values of...

Freeze-drying and gamma irradiation are the techniques widely use in tissue banking for preservation and sterilization of tissue grafts respectively. However, the effect of these techniques on biomechanical properties of bovine pericardium is poorly known. A total of 300 strips of bovine pericardium each measured 4 cm 1 cm were used in this study to evaluate the effect of freeze-drying on biome...

Freeze-dried B.C.G. of British manufacture became available for experimental work in 1955. The main reason for introducing it was the need for a vaccine which would retain its potency under conditions of prolonged storage. On reconstitution for injection the vaccine should produce a uniform suspension with minimal clumping, resulting in a uniform viable bacterial count. These properties mean th...

The present study was designed to examine the effect of freeze-dried soybean curd (tofu) on various bodily functions. The dietary experiment consisted of 4 days of a non-prescribed ordinary diet, 10 days of an experimental diet that contained 190 g of meat contributing about 38 g of protein (hereinafter referred to as the "meat period"), and 39 days of an experimental diet that contributed vege...

sorption isotherm and thermal properties of powders were used for determining stability during storage. garlic slices with 2 mm thickness were dried, using two methods of freeze and cabinet drying. the results showed that, the density, loss of pyruvate and color changes of the freeze dried powder were less than those of the cabinet dried powder. sorption isotherm curves of the both garlic powde...

Solid dispersions of artemether and polyethylene glycol 6000 (PEG6000) were prepared in ratio 12 : 88 (group-1). Self-emulsified solid dispersions of artemether were prepared by using polyethylene glycol 6000, Cremophor-A25, olive oil, Transcutol, and hydroxypropyl methylcellulose (HPMC) in ratio 12 : 75 : 5 : 4 : 2 : 2, respectively (group-2). In third group, only Cremophor-A25 was replaced wi...
