the split-block experimental design with three replications was used to study the effect of subsoiling in different distances from drain axison soil salinity,and wheat yield. the measurements included soil cone index, soil bulkdensity, infiltration rate and electrical conductivity of saturated extract. each treatment was composed of two factors. the main factors consisted of 3 different distanc...

Previous studies of the effects of parity and social isolation on maternal behaviour in guinea pigs were either concerned with subsets of maternal behaviour or based their conclusions on small data sets. The aim of the present experiment was to give a more detailed and complete description of maternal behaviour, including the effects of the sex of the pups on maternal behaviour. Three groups of...

Salmonella outbreaks have been linked to a wide variety of foods, including recent nationwide outbreaks. Guinea pig (Cavia porcellus), also known as cuy or cobayo, has long been a popular delicacy and ceremonial food in the Andean region in South America. This case report describes three family outbreaks of nontyphoidal salmonellosis, each occurring after a meal of guinea pigs. We believe this ...

The histological morphology of oviduct epithelia have been described well, however, the expression pattern of the gap junction proteins in the cells, and the function related with the proteins, such as [Ca2+]i dynamics pattern of living oviduct epithelia at different ages have not been clarified. We used immunohistochemistry to compare the expression pattern of gap junction proteins in the cell...

Form deprivation (FD) was induced in 61 guinea pigs with a diffuser worn on one eye. The form-deprived eye elongated and developed myopia within 6 days in animals raised under a 12:12 h light/dark cycle, but not when reared in darkness. After 11 days of FD, the average eye was -6.6 D more myopic and 146 microm longer than its fellow eye. Initially the myopia was mostly from vitreous chamber elo...

Conditional independence provides an essential framework to deal with knowledge and uncertainty in Artificial Intelligence, and is fundamental in probability and multivariate statistics. Its associated implication problem is paramount for building Bayesian networks. Unfortunately, the problem does not enjoy a finite ground axiomatization and is already coNP-complete to decide for restricted sub...

Behavioral discrimination tests and electroretinogram (ERG) flicker photometry were used to measure spectral sensitivity and to define the spectral mechanisms of the guinea pig (Cavia porcellus). Results from these 2 approaches converge to indicate that guinea pig retinas contain rods with peak sensitivity of about 494 nm and 2 classes of cone having peak sensitivities of about 429 nm and 529 n...

The guinea pig (Cavia porcellus) is a natural reservoir for Trypanosoma cruzi but has seldom been used as an experimental infection model. We developed a guinea pig infection model for acute and chronic Chagas disease. Seventy-two guinea pigs were inoculated intradermally with 10(4) trypomastigotes of T. cruzi strain Y (experimental group); 18 guinea pigs were used as control group. Eight anima...
