The multiple roles of trichomes in two Croton species.

Trichomes are common in plants from dry environments, and despite their recognized role in protection and defense, little is known about their role as absorptive structures and in other aspects of leaf ecophysiology. We combine anatomical and ecophysiological data to evaluate how trichomes affect leaf gas exchange and water balance during drought. We studied two congeneric species with pubescent leaves which co-occur in Brazilian Caatinga: Croton blanchetianus (dense trichomes) and Croton adenocalyx (sparse trichomes).

Pentacyclic triterpene-loaded emulsion stabilized by Agaricus blazei Murill polysaccharides: Factorial design and cytoprotection study.

In this study, pentacyclic triterpene-loaded emulsions were stabilized by polysaccharides from Agaricus blazei Murill mushroom (PAb). The drug-excipient compatibility results by Fourier Transform Infrared Spectroscopy (FTIR) and Differential Scanning Calorimetry (DSC) showed the absence of physicochemical incompatibilities. The use of these biopolymers at 0.

Antagonism of volatile organic compounds of the Bacillus sp. against Fusarium kalimantanense.

Fusarium kalimantanense is a genetic lineage of Fusarium oxysporum f. sp. cubense (Foc) and belongs to the Fusarium oxysporum species complex (FOSC).

Trichoderma longibrachiatum as a biostimulant of micropropagated banana seedlings under acclimatization.

The use of growth-promoting microorganisms with biostimulant characteristics is an important biological asset for the acclimatization of micropropagated seedlings. The present study aimed to evaluate the efficacy of the application of Trichoderma spp. on the promotion of the growth of micropropagated banana seedlings during acclimatization.

Cashew apple ( L.) extract from a by-product of juice processing: assessment of its toxicity, antiproliferative and antimicrobial activities.

Cashew apple extract (CAE) is a product with intense yellow color obtained from residual fibers of juice processing. Although CAE is known to be rich in carotenoids and anacardic acids, the biological activities of this potential natural food colorant remain unexplored. The present study is the first to investigate the toxicity, antiproliferative and antimicrobial activities of the lyophilized CAE (L-CAE) and its encapsulated products, using maltodextrin (M-CAE) or cashew gum (CG-CAE) as carriers.

Resorbable bacterial cellulose membranes with strontium release for guided bone regeneration.

Hybrid materials, based on bacterial cellulose (BC) and hydroxyapatite (HA), have been investigated for guided bone regeneration (GBR). However, for some GBR, degradability in the physiological environment is an essential requirement. The present study aimed to explore the use of oxidized bacterial cellulose (OxBC) membranes, associated with strontium apatite, for GBR applications.

In vitro degradability and bioactivity of oxidized bacterial cellulose-hydroxyapatite composites.

Hydroxyapatite-associated bacterial cellulose (BC/HA) is a promising composite for biomedical applications. However, this hybrid composite has some limitations due to its low in vivo degradability. The objective of this work was to oxidize BC and BC/HA composites for different time periods to produce 2,3 dialdehyde cellulose (DAC).

Eggs hatching and oncomiracidia lifespan of Dawestrema cycloancistrium, a monogenean parasitic on Arapaima gigas.

Within the production chain of the Arapaima gigas (pirarucu), sanitary issues are still faced at the fingerling phase regarding infestations by the monogenean Dawestrema cycloancistrium. The present study had the objectives of describing the morphology and development phases of this parasite's eggs and oncomiracidia and determining the hatching time and lifespan of the oncomiracidia at different temperatures. D.

Carnauba wax p-methoxycinnamic diesters: Characterisation, antioxidant activity and simulated gastrointestinal digestion followed by in vitro bioaccessibility.

The beneficial biological effects of cinnamic acid derivatives and the lack of studies on the antioxidant activity and bioavailability of cinnamic esters from carnauba wax, diesters were extracted from carnauba wax powder. Their structural, physical and morphological characteristics, antioxidant activity and in vitro bioaccessibility were measured. p-Methoxycinnamic diester (PCO-C) was identified, which has a crystalline, apolar structure and exhibited significant antioxidant activity (107.
