INTRODUCTION Diuretic responsiveness in patients with chronic heart failure (CHF) is better assessed by urine production per unit diuretic dose than by the absolute urine output or diuretic dose. Diuretic resistance arises over time when the plateau rate of sodium and water excretion is reached prior to optimal fluid elimination and may be overcome when hypertonic saline solution (HSS) is added...

STUDY OBJECTIVES Aspiration pneumonia, a leading cause of death in patients with Parkinson disease (PD), usually occurs at the advanced stages of the disease. We investigated both motor and sensory components of cough and induced-sputum substance P (SP) concentrations in patients with early and advanced stages of PD to assess whether cough efficacy is impaired in PD. SUBJECTS Fifteen female p...

ophthalmia neonatorum is generally defined as conjunctivitis occurring within one month of life. the sources of this infection are environmental organisms or the organisms colonized in the birth canal. untreated infection can cause blindness, especially if the corresponding organisms areneisseria gonorrhoeae, or chlamydia trachomatis. povidone-iodine ophthalmic solution is an effective antibact...

background: the presence of heavy metals in aquatic and terrestrial ecosystems causes harmful effects to living organisms in the environment. this research aimed to determine the potential of activated pumice stone (aps) as a sorbent for the removal of cd, cu, and zn from wastewater. methods: this research was conducted during 2013 on a laboratory scale. the study was performed using batch expe...

thermal behavior of various solid feldspars are different, namely those of bivalent cations show no change in the distribution of al and si atoms, whereas feldspars of univalent cations become more disordered with raising temperature. in the latter case al atoms migrate from the sites they occupe at low temperatures and interchange positions with the si atoms. at high temperatures (but still be...

introduction: discharging of industrial colored wastewaters especially into aqueous environments can cause adverse effects on aquatic life due to their toxic natures. in this study, montmorillonite modified by hexadecyltrimethyl ammonium bromide (hdtma-mt) was used for the adsorption of methylene blue (mb). materials and methods: the influence of surfactant loading rate, contact time, ph, adsor...

this paper studies the biswas-milovic equation with log law nonlinearity. thegausson solution is obtained by the ansatz method. subsequently, theconservation laws are derived and the conserved quantities are computed usingthe gausson solution.

in this article a new and an accurate method for kinematic and dynamic analysis of a parallel robot 3prs and a hybrid robot (parallel and serial) 3prs-rrp are presented, which is based on the denavit-hartenberg transformation matrix algebra. first, basic properties of various kinds of robots are compared, and then the denavit-hartenberg parameters and their table are introduced. next, the metho...

background solid organ transplantation patients are at high risk for opportunistic air-borne fungal infections due to using the potent immunosuppressive agents. objectives the current study aimed to qualitatively and quantitatively evaluate the fungal flora present in the air of kidney transplant unit of baqiyatallah hospital. materials and methods in this prospective study, air samples from pa...

abstract objective removing plasma from the platelet concentrate (pc) medium could be an effective way to increase the safety of this product. the goal of this study was to compare pc stored in plasma or in an additive solution (composol) with in vitro testing. materials and methods fifty-four single donor pcs were prepared from iranian blood transfusion organization (ibto). each pc unit was di...
