saffron, the dried red-orange stigmas of crocus sativus l, has been known as a flavoring agent, food coloring and traditional herbal medicine. pharmacological effects of saffron are mainly attributed to crocin, crocetin, picrocrocin and safranal. these components especially crocin, have significant effects including antidepressant and anticonvulsant, analgesic, anti-cancer and other therapeutic...

microcerotermes diversus silvestri (isoptera: termitidae) is the most economically destructive wood pest in structures in khuzestan province (iran). chemicals such as essential oils and plant extracts that are compatible with the environment and have high potential to be used in integrated pest management programs are extremely important resources. this study evaluated contact and digestive tox...

Digestive system neoplasms are the leading causes of cancer-related death all over the world. Solute carrier (SLC) superfamily is composed of a series of transporters that are ubiquitously expressed in organs and tissues of digestive systems and mediate specific uptake of small molecule substrates in facilitative manner. Given the important role of SLC proteins in maintaining normal functions o...

the snail caucasotachea lencoranea mousson is a pest of citrus in the north provinces of iran. in order to adopt a better control of the pest and develop optimal management strategies, an understanding of the digestive enzymes’ function is inevitable. snails were collected from some citrus orchards in the northern provinces of the country and digestive carbohydrases including ?-glucosidase, ?-g...

A receptor binding and digestive activity of human polymorphonuclear leukocytes (PMNs) toward formyl-methionyl-leucyI3H]phenylalanine (3H-FMLP) was examined with the following results: (1 ) Upand down-regulation and recovery of 3H-FMiP binding activity were demonstrated. (2) Both intact PMN and a lysate prepared from them cleaved the carboxyl terminal amino acid (phenylalanine) of 3H-FMiP. (3) ...

In considering the use of digestive enzyme supplements, it is not uncommon to question the survivability of unprotected enzymes through the digestive process. Pancreatic enzymes, available as both drugs and dietary supplements, are known to require enteric coating to prevent permanent denaturing by gastric acidity. Fortunately, not all enzymes require these coatings to survive the gastric envir...

There are many causes of digestive problems, and in general the causes are similar for dogs and cats. However, prevalence of the various digestive problems differs for each species. The most common signs of digestive problems are vomiting and diarrhea. Other less common clinical signs of digestive problems include constipation, bloat, abdominal pain, excessive salivation, difficult swallowing, ...

The digestive tract exhibits region-specific morphology and cytodifferentiation along the anteroposterior axis. We analyzed the spatial expression patterns of Hox genes belonging to the HoxA and HoxB cluster (Hoxa-4 approximately a-9, Hoxb-5 approximately b-9) in the developing chick digestive tract. The expression domains of these Hox genes correlated with morphological subdivision of the dige...

As reported by earlier investigators, the epithelium of the digestive tubules is composed of two cell-types. One type of cell is glandular, the other type is absorptive and digestive, and to a lesser extent secretory. The latter type of cell also contains glycogen and numerous lipid globules, so that the digestive gland as a whole contains a large quantity of reserve food material. The epitheli...
