Ultrathin frozen sections of biological tissues for electron microscopy provide certain advantages in cytochemical studies in which the penetration of cells by large molecules is necessary and in morphological studies of cellular constituents which are dissolved by the reagents employed in routine plastic embedding. The recent introduction of several types of commercially available cryo-ultrami...

Pepino (Solanum muricatum Aiton), also known as melon-pear, is a vegetatively propagated vegetable crop grown for its juicy and aromatic fruit. Great variation in fruit weight, shape, and color can be found among cultivars of pepino (Anderson et al., 1996; Heiser, 1985). Despite being an important crop in Pre-Columbian times in the Andean region, it has not achieved the same relevance as other ...

If you are sharing a meal with a companion, how best to make sure you get your favourite fork-fulls? Ethiopian Dinner is a game in which two players take turns eating morsels from a common plate. Each morsel comes with a pair of utility values measuring its tastiness to the two players. Kohler and Chandrasekaran discovered a good strategy — a subgame perfect equilibrium, to be exact — for this ...

Bananas are cultivated in more than 120 countries and on the five continents in tropical and subtropical areas [7]. Bananas production is the fourth most significant of the world in terms of tonnage, after rice, wheat and maize. In 2013, world production was estimated at more than 106 million tons, of which 2 million produced in Caribbean [8]. However, only a small part is produced for commerci...

background and objectives: thyroid gland because of its superficial location is amenable to direct physical examination. clinical assessment of thyroid lesions by means of physical examination, thyroid scans and ultrasonography is not completely reliable. fine needle aspiration cytology (fnac) is the most cost-effective, safe and an initial diagnostic test in the pre-operative evaluation of thy...

abstract background: fresh bread has a short shelf life and by considering this matter, its acceptability by consumer dramatically would reduce by increasing the time between baking and consumption. use of frozen dough technology is one of solution for this problem. therefore in this current study the impact of freezing storage and pre-fermentation in sangak frozen dough and its bread was consi...

Background and objective: To determine the diagnostic accuracy and pitfalls of frozen section in ovarian tumors in one of the largest university affiliated gynecologic oncology centers in Tehran, and determine the cause of discrepancies. Materials and Methods: We retrospectively analyzed the results of frozen section and permanent diagnoses of ovarian masses by reviewing the reports in the dep...

  The effect of gamma radiation (1, 3 and 5 kGy) on microbial quality of farmed rainbow trout (Oncorhynchus mykiss) fillets which were stored under frozen conditions (-20° C) was studied by measuring microbiological changes in 5 months. Gamma irradiation and increasing of frozen storage time had significant effects (P<0.05) on the reduction of microorganism's population. The total count showed ...

Background:The diagnostic accuracy of frozen section as an important source of information in surgical pathology is important not only in the management of surgical patients but also as a measure of quality control in surgical pathology. In this study, we evaluated the diagnostic accuracy of frozen sections over a 6-year period in a teaching hospital in Iran. Methods: We retr...
