contact hypersensitivity (chs) mouse model induced by 2, 4-dinitrofluorobenzene (dnfb) is thought to be a t helper 1 (th1)-dominant response and used for investigating anti-inflammatory and immunosuppressive agents. however, it is hardly used for screening large-scale drugs because of the large number of animals and complex mechanisms involved in-vivo. in this study, we focused on whether t lym...

Background: Shift work can cause problems for workers’ health, especially nurses. This study was done to assess the problems caused by shift work and the nature of the job in nurses of the educational hospitals of Kerman University of Medical Sciences, Iran. Materials and Methods: This was a descriptive study carried out in 2013. The research participants were 159 nurses with and without...

Two adaptive FIR filter configurations are proposed for implementing the LMS algorithm with no along delay elements or multipliers. The first uses a linear feedback shift register (LFSR) to generate pseudorandom binary sequences for applications where white noise has been traditionally used. The binary signals are delayed by a shift register and multiplied by on/off switching so that the result...

OBJECTIVES Lack of physical activity (PA) has been hypothesised as an underlying mechanism in the adverse health effects of shift work. Therefore, our aim was to compare non-occupational PA levels between shift workers and non-shift workers. Furthermore, exposure-response relationships for frequency of night shifts and years of shift work regarding non-occupational PA levels were studied. MET...

We calculate the shift current response, which has been identified as the dominant mechanism for the bulk photovoltaic effect, for the polar compounds LiAsS2, LiAsSe2, and NaAsSe2. We find that the magnitudes of the photovoltaic responses in the visible range for these compounds exceed the maximum response obtained for BiFeO3 by 10-20 times. We correlate the high shift current response with the...

Background: Artemisia diffusa contains a new type of sesquiterpene lactone with an endoperoxide group (Tehranolide). Objective: Due to the existing similarity between the structures of Tehranolide and Artemisinin, it was hypothesized that Tehranolide would have similar effects as Artemisinin. In this study, the immunotherapeutic effec-tiveness of Tehranolide was investigated by direct intra-tum...

extract  skillful management role in the success of any profession is clear. nursing as profession is no exception to this fact. also nursing mission and role in human life are heavier and require more complex management skills .   evening and night shift nursing supervisor are employed by a health care institution such as a hospital in the absence of nursing management must have knowledge and ...

purpose: to report the refractive changes after intraocular lens (iol) implantation in children with congenital and developmental cataract. methods: in this historical cohort study, the clinical records of children between 2 and 15 years old that had lensectomy with posterior capsulotomy, anterior vitrectomy and iol implantation with more than 5 years of follow-up were studied. refractive error...
