Microbial drivers of root plasticity. [PDF]

open access: yesNew Phytol
Summary Soils are highly heterogeneous and dynamic systems, experiencing a constant flow of plant root exudates and moisture fluctuations that affect nutrient distribution, soil physicochemical properties, and microbial metabolisms. Plant roots adjust their development within the soil matrix (growth, branching, root angle, and anatomical features) by ...

Physiological roles of lignins - tuning cell wall hygroscopy and biomechanics. [PDF]

open access: yesNew Phytol
Summary Lignins constitute the second most abundant carbon‐storing biopolymers in the biosphere. These phenolic polymers accumulate in different concentrations, compositions, and localisations within and between cell wall layers and cell types. Lignins were acquired during plant terrestrialisation 450 million years ago, and the diversification of their

Transdermal drug delivery in horses: An in vitro comparison of skin structure and permeation of two model drugs at various anatomical sites

open access: yesVeterinary Dermatology, Volume 34, Issue 3, Page 235-245, June 2023., 2023
Background – Oral and parenteral drug delivery in horses can be difficult. Equine‐specific transdermal drug formulations offer improved ease of treatment; development of such formulations requires a deeper understanding of the structural and chemical tissue barrier of horse skin. Hypothesis/Objectives – To compare the structural composition and barrier

Variation in biomass allocation and root functional parameters in response to fire history in Brazilian savannas

open access: yesJournal of Ecology, Volume 109, Issue 12, Page 4143-4157, December 2021., 2021
Fire stimulated the increase of absorptive root biomass in the upper soil layer in response to the higher demand for below‐ground resources, but did not promote modification of morphological root parameters. Differences in morphological root parameters reflected variation in soil properties, especially soil P, as well as differences in graminoid ...

Evaluation of Mucoadhesive Gels with Propolis (EPP‐AF) in Preclinical Treatment of Candidiasis Vulvovaginal Infection

open access: yesEvidence-Based Complementary and Alternative Medicine, Volume 2013, Issue 1, 2013., 2013
Vulvovaginal candidiasis is the second cause of vaginal infection in the USA. Clinical treatment of C. albicans infections is routinely performed with polyenes and azole derivatives. However, these drugs are responsible for undesirable side effects and toxicity. In addition, C. albicans azole and echinocandin resistance has been described.

Evaluation of a Propolis Water Extract Using a Reliable RP‐HPLC Methodology and In Vitro and In Vivo Efficacy and Safety Characterisation

open access: yesEvidence-Based Complementary and Alternative Medicine, Volume 2013, Issue 1, 2013., 2013
Since the beginning of propolis research, several groups have studied its antibacterial, antifungal, and antiviral properties. However, most of these studies have only employed propolis ethanolic extract (PEE) leading to little knowledge about the biological activities of propolis water extract (PWE). Based on this, in a previous study, we demonstrated

Antimicrobial Brazilian Propolis (EPP‐AF) Containing Biocellulose Membranes as Promising Biomaterial for Skin Wound Healing

open access: yesEvidence-Based Complementary and Alternative Medicine, Volume 2013, Issue 1, 2013., 2013
Among remarkable discoveries concerning propolis, such as antifungal, antiviral, and antioxidant activities, its anti‐inflammatory, and mainly its antibacterial, properties deserve special attention when skin wound healing is concerned. Based on this and knowing the distinctive performance of bacterial (BC) membranes on wound healing, in this work it ...
