ETHNOPHARMACOLOGICAL RELEVANCE Peppers from Capsicum species (Solanaceae) are native to Central and South America, and are commonly used as food and also for a broad variety of medicinal applications. AIM OF THE STUDY The red pepper Capsicum baccatum var. pendulum is widely consumed in Brazil, but there are few reports in the literature of studies on its(More)
Invasive aspergillosis (IA) seems to be an emerging condition in intensive care units (ICUs). However, little attention has been given to the role of environmental factors that could increase the risk for IA in the ICU. The objective of this study was to determine the concentration of airborne fungi in three Brazilian ICUs, in an attempt to correlate fungal(More)
Invasive fungal diseases have emerged as important causes of morbidity and mortality in haematological patients. In this study air samples were collected in two haematopoietic stem cell transplantation (HSCT) units, in which distinct air-control systems were in place. In hospital 1 no high-efficiency particulate air (HEPA) filter was available whereas in(More)
In this study a novel heat-stable lipid transfer protein, designated McLTP1, was purified from noni (Morinda citrifolia L.) seeds, using four purification steps which resulted in a high-purified protein yield (72 mg McLTP1 from 100g of noni seeds). McLTP1 exhibited molecular masses of 9.450 and 9.466 kDa, determined by electrospray ionisation mass(More)
This study describes and characterizes methods for high-performance liquid chromatography diode array detection (HPLC-DAD) analysis of formulations containing molecules with antifungal activity of three different classes: terbinafine and butenafine (allylamines), miconazole and fluconazole (azoles), and geraniol, neral and geranial (monoterpenes). All(More)
INTRODUCTION Acute kidney injury (AKI) remains a great problem in clinical practice. Renal ischemia/reperfusion (I/R) injury is a complex pathophysiological process. Propolis is a natural polyphenol-rich resinous substance collected by honeybees from a variety of plant sources that has anti-inflammatory and anti-oxidative properties. Red propolis (RP)(More)
The plant Cocos nucifera and its derivatives have shown antidepressant-like effects, although its hydroalcoholic extract has not been studied with this end in mind. Therefore, we decided to determine the antidepressant-like effects of the standardized hydroalcoholic extract of Cocos nucifera husk fiber (HECN) as well as oxidative alterations in the(More)
Environmental air monitoring is a common practice in many institutions. However, the methodology involved in different studies has not been standardized, with most centers incubating samples at room temperature. Here we demonstrate that the incubation of plates at 35-40°C facilitates growth of Aspergillus section Fumigati, the most important pathogenic mold(More)
A simple visible spectrophotometric method was developed for the determination of gemifloxacin mesylate (GFM) in tablets. The method was based on the formation of a yellow ion-pair complex between the basic nitrogen of the drug and the sulfonphthalein acid dye in phthalate buffer. The method was validated by the study of its specificity, linearity,(More)
A stability-indicating micellar electrokinetic chromatography (MEKC) method was developed and validated for simultaneous analysis of delapril (DEL) and manidipine (MAN) using salicylic acid as an internal standard. The MEKC method was performed using a fused-silica capillary (effective length of 72 cm) with 50 mM of borate buffer and 5 mM of anionic(More)
