Valorization of the peel and husk of guaraná (Paullinia cupana): oil extraction, chemical composition, cytotoxicity, and antitumor potential

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract Guaraná (Paullinia cupana) is a fruit native to the Amazon region. Due to its widespread use, primarily in beverages, its production has grown over the years. The seed is the only commercially valuable part of the fruit so the guaraná production chain generates byproducts, including peel, husk, and spent seed.

Optimizing biophysical properties of cellular niches to enhance stem cell‐derived extracellular vesicle function in musculoskeletal regeneration

open access: yesBMEMat, EarlyView.
Extracellular vesicles (EVs) derived from stem cells show promise for applications in regenerative medicine, but their scalability and yield remain challenges. This review explores the approaches for biophysical modulations within cell niches on EV properties, discusses the current clinical application of EVs, and provides an outlook on the existing ...

Reading hominin life history in fossil bones and teeth: methods to test hypotheses regarding its evolution

open access: yesBiological Reviews, EarlyView.
ABSTRACT Human life history is derived compared to that of our closest living relatives, the great apes. It has been suggested that these derived traits are causally related to aspects of our ecology, social behaviour and cognitive abilities. However, resolving this requires that we know the evolutionary trajectory of our distinctive pattern of growth,

Considerations during crown reattachment procedure over the pulpal exposure: case report

open access: yesRestorative Dentistry & Endodontics, 2012
Crown reattachment is the most conservative treatment which can be used to restore fractured tooth, presumably with sufficient strength, while maintaining original contour, incisal translucency, and reducing chair time and cost.

Systemic evaluation of various haemostatic agents following local application prior to direct pulp capping

open access: yesBrazilian Journal of Oral Sciences, 2015
Limited physiological information is available regarding the role of hemostatic agents to control the success of direct pulp capping treatment in order to help save vital pulps from pulpotomy, pulpectomy or extraction.

The Impact of Carbon Pricing on Corporate Sustainability: Evidence From the European Union

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT The European Union (EU) has played a leading role in the fight against climate change. One mechanism used to meet the targets for global greenhouse gas (GHG) emission reductions is carbon pricing. A prominent example is the EU Emissions Trading System (EU‐ETS).

Board That Transforms: Relationship Between Board Structure and Environmental, Social, and Governance Performance in BRICS Countries

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT The purpose of this study is to examine the relationship between board composition characteristics and ESG performance in companies from BRICS countries, and to assess how sector sensitivity moderates this relationship. A sample of 2045 BRICS companies was examined using panel data regression with random effects and logistic regression ...

Dental development in the tropical gar (Atractosteus tropicus) and the evolution of vertebrate dentitions

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Dentitions have diversified enormously during vertebrate evolution, involving reductions, modifications, or allocations to prey seizing and processing regions. A combination of ancient and novel features related to dental and oropharyngeal apparatuses is found in extant lineages of non‐teleost fishes, such as the gars.
