Although support vector machine (SVM) has become a powerful tool for pattern classification and regression, a major disadvantage is it fails to exploit the underlying correlation between any pair of data points as much as possible. Inspired by the modified pairwise constraints trick, in this paper, we propose a novel classifier termed as support vector machine with hypergraph-based pairwise con...
Background: Historically open surgical drainage has been the treatment of choice for pyogenic liver abscess. The records of 54 patients with pyogenic liver abscess were reviewed to determine whether earlier diagnosis with current imaging tests and definitive treatment with antibiotics and aspiration drainage was an effective alternative to surgery. Methods: The clinical features, laborator...
Background and purpose: Ventilator-associated pneumonia (VAP) is one of the major factors of mortality and morbidity in Intensive care units (ICUS), especially in open-heart surgery patients. The purpose of this study was to investigate VAP in open-heart surgery patients admitted to the ICU in Sari Fatemeh Zahra Hospital, 2017-2019. Materials and methods: In this retrospective descriptive cros...
Reactions of chlorine (Cl(2)) with 4-halo-1,1,2-trifluorobut-1-enes (1, 2, or 3) give open-ion intermediates A and E that are in equilibrium. The open-chloronium ions (E) rearrange to a five-membered-ring halonium ion during ionic chlorination of 3 when the number-4 halo-substituent is iodine. Three-membered-ring bromonium and iodonium ions from alkenes 1, 2, or 3 are rather symmetrical and sim...
conclusions ip injection of cb1 receptor antagonist might have an anxiogenic profile in rat, whereas calcium channel blocker attenuated the anxiogenic effect of am251. our results suggest that there is an interaction between functions of l-type ca2+ channels and cannabinoid system in anxiety. background the elevated plus-maze (epm) has been broadly used to investigate anxiolytic and anxiogenic ...
