Urinary albumin and transferrin as early diagnostic markers of chronic kidney disease.

Feline renal diseases are increasingly noted in veterinary practice. It is important to diagnose and identify the pathological basis of renal dysfunction accurately at an early stage, but there are only a few reports on this area in clinical veterinary medicine. We investigated the efficacy of measurement of urinary albumin (u-Alb) and urinary transferrin (u-Tf) for early diagnosis using 5-µl urine samples collected noninvasively by catheterization from normal (IRIS stage I) cats and cats with stage I chronic kidney disease (CKD).

Time course of virulence factors produced by group A streptococcus during a food-borne epidemic.

We studied the protein amount and activity of the major virulence factors hemolysin, cysteine protease streptococcal pyrogenic exotoxin B (SpeB), and NAD glycohydrolase (NADase), which are produced by Streptococcus pyogenes type T-25, with a food poisoning outbreak. The three virulence factors were analyzed by activity and amount of protein using supernatants at 2-30 h of culture. All these virulence factors were confirmed by their activity.

Properties of metabolic substances produced by group A streptococcus from a food-borne epidemic.

Here we report a large food poisoning outbreak by Streptococcus pyogenes that occurred in Kanagawa, Japan, in July 2005. To compare cases of type T-B3264 (Chiba) and type T-28 (Tokyo) reported to date, we studied the properties and activity of the major virulence factors produced by Streptococcus pyogenes type T-25 (Kanagawa): hemolysin, cysteine protease streptococcal pyrogenic exotoxin B (SpeB), and NAD glycohydrolase (NADase). These virulence factors were also analyzed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE).

[Properties of metabolic substance produced by group A Streptococcus from two food-borne epidemic].

We report the finding for two food-poisonins outbreaks occurring in Tokyo and Chiba in September 2003. Patients in the Tokyo outbreak suffered from fever varying widely from 35.9 degrees C to 39.

Novel and extensive aspects of paraquat-induced pulmonary fibrogenesis: comparative and time-course microarray analyses in fibrogenic and non-fibrogenic rats.

Although paraquat (PQ) is widely known to induce pulmonary fibrosis, the molecular mechanisms are poorly understood. Therefore, to bring a new dimension to the elucidation of the mechanisms, we conducted microarray experiments to investigate the expression profiles of 1,090 genes in the lungs during the progressive phase of PQ-induced pulmonary fibrosis in rats. After several s.

Exoenzymes of Trametes versicolor can metabolize coplanar PCB congeners and hydroxy PCB.

Two fractions containing the oxidase activity toward 2,2'-azinobis (3-ethylbenzothiazoline-6-sulfonate) (ABTS) were obtained using ion-exchange DEAE-Sepharose column chromatography of the culture fluid of white-rot fungus, Trametes versicolor. These two fractions can reduce the level of coplanar PCB congeners (Co-PCBs). The ABTS oxidase in the first fraction passed through the DEAE-Sepharose column.
