The ionic bases of the "positive" afterpotential (ap) have been examined in the so-called DInhi neurons of the central nervous system of Cryptomphallus aspersa. In these cells E(K) has been determined and its value compared with the equilibrium, potential of the ap (E(ap)). It has been found that in half of the studied cells the E(K) value is very close to E(ap) whereas in another half, the dif...

A 56-year-old woman from southwestern Minnesota underwent an extended left hepatic lobectomy to remove a large multinodular mass with a necrotic central cavity. The clinical, serological, and pathological findings led to the diagnosis of alveolar hydatid disease, and specific identification of Echinococcus multilocularis was achieved by growing mature larvas in voles inoculated intraperitoneall...

Although Minnesota has a predominantly White, nativeborn population, in recent years it has experienced large increases in its foreign-born population, leading to Minnesota being designated a “nontraditional destination state.” More than half of the foreign-born population entered Minnesota between 1990 and 2000, increasing its immigrant population by 138%, compared to 57% nationwide. Concentra...

Interruption of the baroreceptor reflex by transection of afferent nerves (sinoaortic denervation; SAD) or lesions of nucleus tractus solitarius (NTS) elevates sympathetic nerve activity (SNA) and arterial pressure (AP). However, within 1 wk, mean AP returns to normal despite the absence of baroreflexes. In this study, we examine central mechanisms that control AP in chronic baroreceptor-denerv...

Experiments were performed to determine if glucocorticoids potentiate central hypertensive actions of ANG II. Male Sprague-Dawley rats were treated for 3 days to 3 wk with corticosterone (Cort). Experiments were performed in conscious rats that had previously been instrumented with arterial and venous catheters and an intracerebroventricular guide cannula in a lateral ventricle. Baseline arteri...

introdouction: the high prevalence of apical periodontitis (ap) of endodontic origin raises an important public health problem. root canal treatment (rct) and crown restoration (cr) have an effect on its prevalence. this cross-sectional study was performed to assess the effect of rct and cr on the prevalence of ap. materials and methods: two observers assessed 608 teeth with rct belonging to pa...

      This study was designed to explore the protective effects of Abrus precatorius L. (Leguminosae) (AP) in HepG2 cells and N-nitrosodiethylamine (NDEA) induced hepatocellular carcinoma in Swiss albino rats. The effects of aqueous/ethanolic (50%) extract of AP on hepatic markers, haematological and histopathological parameters, and antioxidant enzymes were evaluated in NDEA ...

The present study aimed to assess the prevalence of apical periodontitis (AP) in an urban Brazilian population according to gender, age group and tooth type. Data were collected from clinical files containing the medical and dental histories and periapical radiographs of 1,126 patients treated at the School of Dentistry at Universidade do Estado do Rio de Janeiro between March 2000 and December...
