Eugenia brasiliensis: Analysis of the Chemical Profile and Evaluation of Cytotoxic Potential

open access: yesChemistry &Biodiversity, EarlyView.
Leaves of Eugenia brasiliensis were dried, crushed and macerated with polarity increment. The antiporliferative and anti‐migratory potential and the cell cycle were evaluated. 28 compounds were tentatively identified by mass sceptrometry. ABSTRACT This work evaluated the antiproliferative potential of Eugenia brasiliensis leaf extracts against the HeLa

Brazilian Biomes as Promising Resources of Rhodotorula Yeasts for the Biotechnological Production of Carotenoids

open access: yesChemistry &Biodiversity, EarlyView.
ABSTRACT Yeasts belonging to the genus Rhodotorula are capable of synthesizing carotenoids, such as β‐carotene, γ‐carotene, torulene, torularodine, and astaxanthin. These carotenoids have been shown to offer health benefits to humans, such as immune system strengthening and a reduced risk of chronic degenerative diseases.

Ethnomedicinal Uses, Phytochemistry, Pharmacological Activities, and Toxicology of the Subfamily Gomphrenoideae (Amaranthaceae): A Comprehensive Review

open access: yesChemistry &Biodiversity, EarlyView.
ABSTRACT The subfamily Gomphrenoideae is composed of about 480 accepted species, many of which have been historically used as medicinal plants, reason why they have been studied in terms of chemical profile, biological activity, and safety. This review consolidates the advances in research on this subfamily over the past 47 years, emphasizing its ...

Characterization of the Cubamyces Menziesii Terpenome

open access: yesChemBioChem, EarlyView.
The genome of Cubamyces menziesii reveals 18 putative sesquiterpene cyclase genes. These genes are cloned and expressed in Escherichia coli, yielding 10 active enzymes. Using farnesyl diphosphate as substrate, the enzymes are analyzed, and the products characterized after bioconversion, uncovering diverse sesquiterpene structures. This study highlights

The Ultrastructure of the Apical Organ of the Goette's Larvae of the Polyclad Flatworm Stylochus pilidium Indicates Homology Between Polyclad Larvae

open access: yesCell Biology International, EarlyView.
ABSTRACT Polyclad flatworms exhibit both direct and indirect development, with various larval types observed, including Müller's larva, Kato's larva, Goette's larva and Curini‐Galletti's larva. The different larval types are distinguished by shape, number of eyes and number of lobes.

Unveiling the Materiality of 19th Century's Color Spaces

open access: yesColor Research &Application, EarlyView.
ABSTRACT Several color theories flourished during the 19th century, marked by experiments on the distinction between color‐light and color‐matter. This study aims to compare the color plates designed to illustrate three of these color theories, namely M.E. Chevreul's chromatic circle (1861), O. Rood's frontispiece (1879), and C.

Aging and Color Vision: A Model Using the Farnsworth‐MUNSELL 100‐Hue Test

open access: yesColor Research &Application, EarlyView.
ABSTRACT Introduction This study examined the theoretical changes in the FM100 Hue scores induced by age‐related changes in the ocular media transmittance. These changes were analyzed with and without a von Kries‐type chromatic adaptation to determine the role of this adaptation process on age‐related changes in hue discrimination.
