Reconstructing enzyme evolution by protein engineering

open access: yesFEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Morphogenesis in guinea grass pastures under rotational grazing strategies

open access: yesRevista Brasileira de Zootecnia, 2012
This study was conducted in order to evaluate the morphogenetic and structural characteristics of guinea grass cv. Mombasa under three post-grazing heights (intense - 30 cm, lenient - 50 cm and variable - 50 in spring-summer and 30 cm in autumn-winter ...

Longer cutting intervals on the characteristics of Guinea grass: morphogenetic, productive, and nutritional traits

open access: yesActa Scientiarum: Animal Sciences, 2023
The aim of this study was to examine the effect of longer cutting intervals on morphogenetic and structural traits, herbage production, nutritional value, and in vitro digestibility of Guinea grass cv. Mombaça (Mombaça grass). Four cutting intervals (49,

Observed and estimated leaf appearance of landrace and improved maize cultivars [PDF]

open access: yesCiência Rural, 2017
ABSTRACT: The objective of this study was to compare the simulations of leaf appearance of landrace and improved maize cultivars using the CSM-CERES-Maize (linear) and the Wang and Engel models (nonlinear). The coefficients of the models were calibrated using a data set of total leaf number collected in the 11/04/2013 sowing date for the landrace ...

Circular RNA expression landscapes in myelodysplastic neoplasms: Associations with mutational signatures and disease progression

open access: yesMolecular Oncology, EarlyView.
In this explorative study, the abundance of circular RNA molecules in bone marrow stem cells was found to be elevated in patients with high‐risk myelodysplastic neoplasms, and to be associated with an increased risk of progression to acute myeloid leukemia.

EDNRB‐dependent endothelin signaling reduces proliferation and promotes proneural‐to‐mesenchymal transition in gliomas

open access: yesMolecular Oncology, EarlyView.
Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated

Desenvolvimento vegetativo em diferentes hastes da planta de mandioca em função da época de plantio Vegetative development on different stems of cassava as a function of planting date

open access: yesCiência Rural, 2009
Estudos sobre o desenvolvimento vegetativo da mandioca cultivada nas condições subtropicais do Brasil são escassos. O objetivo deste trabalho foi determinar o filocrono e o número final de folhas na haste principal e nas ramificações simpodiais de uma ...

Morphogenesis in pastures with Tanzania grass fertilized with nitrogen doses under a grazing system

open access: yesActa Scientiarum: Animal Sciences, 2015
The morphogenetic and structural characteristics, coupled to forage production of Tanzania grass with nitrogen (N) doses during the seasons of the year, at intermittent grazing, were analyzed.

The appearance of rabbit production given Leucaena leaf flour in the ration

open access: yesE3S Web of Conferences, 2023
Feed is one of the most substantial aspects of financing in the rabbit farming business. Rabbits can breed efficiently with cost-effective feed. This study aims to assess the impact of incorporating Leucaena leaf meal into the diet of rabbits on their growth and production.

Comparative Effectiveness and Safety of Inebilizumab Versus Rituximab in AQP4‐IgG‐Positive NMOSD

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Rituximab (anti‐CD20, RTX) and inebilizumab (anti‐CD19, INE) represent B‐cell‐depleting therapies used for aquaporin‐4 antibody‐positive (AQP4‐IgG+) neuromyelitis optica spectrum disorder (NMOSD); however, direct comparative evidence remains limited.
