BACKGROUND Transvenous pacemaker implantation in dogs is associated with a relatively high complication rate. At our institution, pacemaker implantation in dogs with high-grade atrioventricular block (HG-AVB) frequently is performed as an after-hours emergency. HYPOTHESIS Among dogs with HG-AVB, the rate of major complications is higher when pacemakers are implanted after hours (AH) compared ...

Presynaptic nicotinic acetylcholine receptors (nAChRs) were studied in myenteric plexus preparations from guinea pig ileum using intracellular electrophysiological methods. Microapplication of nicotine (1 mM) caused a biphasic depolarization in all AH neurons (n = 30) and in 36 of 49 S neurons. Cytisine (1 mM) caused fast depolarizations in S neurons and no response in AH neurons. Mecamylamine ...

Background: Second-generation oral antihistamines (AH) and intranasal corticosteroids (ICS) are the most widely used drugs for allergic rhinitis (AR). Objective: To obtain information on the preferences for and applications of these drugs under conditions of routine clinical practice. Methods: We performed a multicenter multidisciplinary observational study. Participating physicians completed a...

OBJECTIVE Alcoholic hepatitis (AH), a unique clinical syndrome among patients with chronic and active alcohol use, is associated with high short-term mortality. An elevated ammonia level is associated with mortality in patients with acute liver failure; however, its impact in AH has not been well-studied. METHODS A retrospective study was performed on patients admitted to a tertiary-care hosp...

the second half of the third hijri century, coinciding with the reign of three caliphs, al-mu’tamid (256-79 ah), al-mu’tadhid (279-89 ah), and al-muktafi (289-95 ah), abbasids restored their authority and renewed their organization. this reform process which was began by abu ahmad al-muwaffaq (d. 278 ah) and reached its climax at the time of abu al-abbas al-mu’tadhid stood between two decline p...

The heats of reaction of trypsin with soybean (Kunitz), ovomucoid, and lima bean inhibitors have been measured at pH 5.0 and 10’ and 25”. All the reactions were endothermic, with AH ranging from 8.6 Cal per mole for the lima bean inhibitor to 15.3 Cal per mole for the soybean inhibitor. Equilibrium constants for the association were calculated from the dependence of residual tryptic activity up...

objective: the aim of this in vitro study was to compare the coronal microleakage between streptococcus sanguis per se and a mixture suspension of e. faecalis and c. albicans in root canals filled with gutta-percha and either ah 26 or ah plus sealer. materials and methods: one-hundred and ten extracted human teeth were decoronated to a standardized root length of 14 mm and prepared using mtwo n...
