In this study, we established hybridoma learn more cell lines producing antibodies against human PGRN. Murine monoclonal antibodies (MAbs) against human PGRN were generated by using purified eukaryotic recombinant PGRN-6His fusion protein as immunogen. A panel of seven monoclonal antibodies was obtained after the preliminary screening by indirect enzyme-linked immunosorbent assay (ELISA), the data of which was confirmed by Western blot analysis and immunocytochemistry. By using constructs expressing a series of C-and N-terminal truncations, and single domains of PGRN, the particular domains recognized by MAbs were also identified. Domain-specific anti-PGRN MAbs will be an essential tool

for investigating the role Adriamycin of PGRN in normal physiological or pathological conditions.”
“Although psychological stress has long been known to alter cardiovascular function, there have been few studies on the effect of psychological stress on platelets, which play a pivotal role in cardiovascular disease. In the present study, we investigated the effects of acute and chronic psychological stress on the aggregation of platelets and platelet cytosolic free calcium concentration ([Ca2+](i)). Mice were subjected to both transportation stress (exposure to novel environment, psychological stress) and restraint stress (psychological stress) for 2 h (acute stress) or 3 weeks (2 h/day)

(chronic stress). In addition, adrenalectomized mice were DMXAA mouse subjected to similar chronic stress (both transportation and restraint stress for 3 weeks). The aggregation of platelets from mice and [Ca2+](i) was determined by light transmission assay and fura-2 fluorescence assay, respectively. Although acute stress had no effect on agonist-induced platelet aggregation, chronic stress enhanced the ability of the platelet agonists thrombin and ADP to stimulate platelet aggregation.

However, chronic stress failed to enhance agonist-induced increase in [Ca2+](i). Adrenalectomy blocked chronic stress-induced enhancement of platelet aggregation. These results suggest that chronic, but not acute, psychological stress enhances agonist-stimulated platelet aggregation independently of [Ca2+](i) increase, and the enhancement may be mediated by stress hormones secreted from the adrenal glands.”
“Purpose The purpose of this study was to assess the influence of identification of the location of the internal opening of anal fistula on the recurrence rate after surgical treatment in patients with primary transsphincteric anal fistulas. The influence of preoperative rectal ultrasound on the treatment results was studied.

Methods One hundred thirty-one patients operated in the period February 1992 to July 2005 were analyzed. Endorectal ultrasound (ERUS) was not performed (till February 2004) on 103 out of the 131 patients, while the other 28 received ERUS (from March 2004).
