Issued 6 January 2006 ABSTRACT The antifungal activities of the ethanol and aqueous crude extracts of four Nigerian chewing sticks were investigated. Also a preliminary phytochemical analysis of the plants was done. The chewing sticks include Anogeissus schimperi, Distemonanthus benthmianus, Vernonia amagdalina and Xanthoxylum zanthoxyloides. All the plants tested, except Anogeissus Schimperi, ...

When we touch something with a tool, we feel the touch at the tip of the tool rather than at the hand that holds the tool. We reported previously that judging the temporal order of two successive stimuli delivered to the tips of straight sticks held in each hand was dramatically altered by crossing the sticks without changing hand position. The results suggested that tactile signals are referre...

OBJECTIVES Traditionally, emergency physicians (EPs) have used anatomic landmark-based needle aspiration to drain peritonsillar abscesses (PTAs). If this failed, an imaging study and/or consultation with another service to perform the drainage is obtained. Recently, some EPs have used ultrasound (US) to guide PTA drainage. This study seeks to determine which initial approach leads to greater su...

health care workers (hcw) are at high risk of occupational exposure from blood-borne pathogens. the most important pathogens that can be transmitted to hcw are hiv with prevalence of 2.24 per 100000, hbv with prevalence of 2.3%, and hcv with prevalence of 0.2% in iran. most of this occupational transmission can be prevented through standard precautions reducing exposure. these precautions, howe...

minimal stimulation in vitro fertilization (mini-ivf) consists of a gentle controlled ovarian stimulation that aims to produce a maximum of five to six oocytes. there is a misbelief that mini-ivf severely compromises pregnancy and live birth rates. an appraisal of the literature pertaining to studies on mini-ivf protocols was performed. the advantages of minimal stimulation protocols are report...

BACKGROUND The Sniffin' Sticks test is a well-developed olfactory test, with normative data having been derived from more than 3,000 subjects in central-northern Europe and Australia. However, as environment affects olfactory function, the purposes of this study were to establish normative data for the Sniffin' Sticks olfactory test in Taiwan, where the climate is different from that of Europe,...
