Murine rodents are excellent models for study of adaptive radiations and speciation. Brown Norway rats (Rattus norvegicus) are successful global colonizers and the contributions of their domesticated laboratory strains to biomedical research are well established. To identify nucleotide-based speciation timing of the rat and genomic information contributing to its colonization capabilities, we a...

The Queen Saovabha Memorial Institute in Bangkok sees approximately 7,000 human postexposure rabies patients yearly, of which approximately 1% are rat bites. In these exposures the rats could not be proven to be rabid because they could not be caught. This report documents a bite from a rat that was proven rabid. Mr. CC, a 45-year-old farmer in Phetchabun Province reported that he was attacked ...

Formiminoglutamic acid is a product derived from the metabolism of histidine by mammalian liver and several microorganisms (l-3). The metabolism of FGA’ is dependent upon the presence of tetrahydrofolic acid (4, 5), and consequently this formimino compound is excreted in the urine of human subjects or laboratory rats which have a deficiency of folic acid (6-8). Daft (6) has reported that suitab...

introduction: marginal adaptation of cast restorations is essential for their long-term success. as dentists usually assign ditching of dies to laboratory technicians, and ditching has a significant effect on marginal adaptation, the aim of this study was to compare ditching by laboratory technicians and standard approach on marginal adaptation of cast restoration. materials and methods: in thi...

the study has strived to compare the leucocyte-esterase stripe activity on sputum samples with gram-stained direct smear microscopy. this is for the demonstration of white blood cells (wbcs) and so to develop a simple method for selecting suitable sputum samples for cultural examination and laboratory diagnosis. . a total of 17(34.0%) out of 50 samples studied were shown to be unsuitable for mi...

background and objective: laboratory errors are one of the major factors that affect the diagnosis, prognosis, treatment and monitoring in patients.the objective of study is to evaluate the frequency and type of errors in different phases of testing at the pathology department of the shalamar hospital, lahore and to evaluate the causes of errors. methods: this observational study was carried o...

At the time of its discovery two decades ago, vitamin E would have been defined as the fifth member of the then small family of vitamins. It was known to be widely distributed in green plants, in the germ of cereal grains, and, to a lesser extent, in animal tissues. It was known to be essential for normal reproduction in the laboratory rat. Although its ability to prevent fetal resorption in th...

Preputial gland is one of the prime sources of pheromones in rats. The study on pheromone identification in preputial gland is well established in laboratory rat, house rat and voles. But the study was lacking in the preputial gland of bandicoot rats. Hence, the present investigation was aimed to identify the volatile and protein profiles of preputial gland of male bandicoot rat. Gas chromatogr...

We present 870 $\mu$m ALMA polarization observations of thermal dust emission from the iconic, edge-on debris disk $\beta$ Pic. While spatially resolved map does not exhibit detectable polarized emission, we detect at $\sim$3$\sigma$ level when averaging across entire disk. The corresponding fraction is $P_\textrm{frac}$ = $0.51 \pm 0.19$%. position angle $\chi$ aligned with minor axis disk, as...
