Degradation by physical and chemical agents affects the properties of essential oils; therefore, this study aimed to protect the volatile compounds present in essential oils through biopolymer encapsulation. The (Lam) DC. essential oil was obtained by steam distillation at 2.

The objective of this study was to evaluate the genetic diversity among traditional common bean accessions through morphological descriptors and molecular markers. Sixty-seven common bean accessions from the Germplasm bank of the Instituto Federal of Espírito Santo-Campus de Alegre were evaluated. For this, 25 specific morphological descriptors were used, namely 12 quantitative and 13 qualitative ones.

is a species of pharmacological interest for providing volatile and non-volatile extracts with antifungal and amebicidal properties. The biological activities of non-volatile extracts may be related to the presence of coumarins, a promising group of secondary metabolites. In the present study, leaves and inflorescences previously used for the extraction of essential oils instead of being disposed of were subjected to extraction with supercritical CO after pretreatment with microwaves.

A widely disseminated native species from Australia, , which is mainly cultivated in Brazil and South Africa, represents a rich source of natural tannins used in the tanning process. Many flowers of the species are used as sources of compounds of interest for the cosmetic industry, such as phenolic compounds. In this study, supercritical fluid extraction was used to obtain non-volatile compounds from flowers for the first time.

Background: Nosodes are homeopathic preparations (HPs) obtained from tissues or substances associated with the targeted disease or from culture of the pathogenic agent. Nosodes are thought to modulate host resistance, easing symptoms or promoting cure. A few studies have been published about control of plant-parasitic nematodes with HPs, but none with nosodes.

Objective: This study aims to correlate new experimental data relevant to the description of the combined evaporation/permeation process of a perfume applied onto the skin.

Methods: The vapour pressure data were measured by thermogravimetric analysis (TG-DTA). The Antoine constants and the Clarke and Glew parameters were determined for the same set of fragrance molecules to describe its low vapour pressures at new temperature ranges.

The authors report a case of a patient who underwent cataract surgery with implantation of a posterior chamber intraocular lens and presented endophthalmitis on the second postoperative day. She was treated with intravitreal injection of amikacin, vancomycin and dexamethasone. After resolution of the infection the patient presented macular infarction and important loss of visual acuity due to amikacin toxicity.

The authors report a case of a 19-year-old patient presenting with type VI mucopolysaccharidosis, diagnosed by genetic-clinical examination, demonstrating several systemic manifestations, including ocular disorders such as: corneal opacity, elevated intra-ocular pressure and increase of corneal thickness. The authors discuss the characteristic syndromic findings and the influence of corneal thickness associated with an increase in intraocular pressure leading to unnecessary antiglaucomatous treatment.
