Retrospective evaluation of potassium hydroxide plus calcofluor white (KOH+CFW), Gram, Giemsa, and modified Ziehl-Neelsen (1% H(2)SO(4), cold) stains for the detection of microsporidia in corneal scrapings from 30 patients showed KOH+CFW and acid-fast stains to be most efficient (29/30 [96.7%] and 28/30 [93.3%], respectively) in the diagnosis of microsporidial keratitis.

In this letter, we investigate the fabrication of Silicon nanostructure patterned on lightly doped (10(15) cm(-3)) p-type silicon-on-insulator by atomic force microscope nanolithography technique. The local anodic oxidation followed by two wet etching steps, potassium hydroxide etching for silicon removal and hydrofluoric etching for oxide removal, are implemented to reach the structures. The i...

BACKGROUND Insufficient data exist on the production of compound A during closed-system sevoflurane administration with newer carbon dioxide absorbents. METHODS A modified PhysioFlex apparatus (Dräger, Lübeck, Germany) was connected to an artificial test lung (inflow at the top of the bellow approximately/= 160 ml/min CO2; outflow at the Y piece of the lung model approximately/= 200 ml/min, s...

Potassium is an alkali-metal denoted by the chemical symbol K and atomic number Z = 19. It has been discovered in 1807 by deriving it from potassium hydroxide KOH. Being an alkali atom it has only one electron in the outermost shell and the charge of the nucleus is being shielded by the core electrons. This makes the element very chemically reactive due to the relatively low ionization energy o...

lamerin microspridia (lbms) isolated from lamerin breed of the silkworm, bombyx mori, l. and the standard strain nosema bombycis, were induced to germinate artificially by two-step procedure. fresh percoll purified spores were activated by incubating them in potassium hydroxide solution (koh) (ph 11.00) and germinated artificially by using phosphate buffer saline (pbs), (ph 7.00). germinated sp...

Alkaline etching of crystalline using KOH (potassium hydroxide), TMAH (tetramethyl ammonium hydroxide), or EDP (ethylenediamene pyrocatecol) is performed for creating various feature definition in MEMS (micro electrical mechanical structures, solar cells, and integrated circuit manufacturing. KOH will be discussed in this section. The alkaline chemistries have the ability to preferentially etch...

BACKGROUND Molluscum contagiosum is a non-severe pediatric viral infection. Because it is highly contagious and current treatments have negative aesthetic and psychological effects, we want to test an alternative treatment in the primary care setting, consisting of two different concentrations of potassium hydroxide solution. METHODS/DESIGN The study design is a double-blind, randomized clini...

In this study, polyvinylidene fluoride (PVDF) flat membranes were treated with potassium hydroxide (KOH), sodium hydroxide (NaOH) and sodium hypochlorite (NaOCl). The effects of temperature, treatment duration and chemical concentration towards the properties of PVDF membrane were contrastively studied. Following treatment, membrane became much brittle with a reduced nominal elongation to as lo...

Surface texturing is demonstrated by the combination of wet etching and ultrafast laser nanostructuring of silica glass. Using potassium hydroxide (KOH) at room temperature as an etchant of laser modified glass, we show the polarization dependent linear increase in retardance reaching a threefold value within 25 hours. The dispersion control of birefringence by the etching procedure led to achr...
