Suplementação de vitaminas e minerais orgânicos nos parâmetros bioquímicos e hematológicos de frangos de corte em estresse por calor

Boletim de Indústria Animal, 2013
O objetivo deste estudo foi avaliar o efeito de dietas suplementadas com vitaminas C e E e minerais orgânicos Zn e Se sobre os parâmetros hematológicos e bioquímicos séricos de frangos de corte sob estresse cíclico por calor (EPC) (25 a 32°C) ou ambiente termoneutro (ATN) (21 a 25°C), ambos com 70% de umidade relativa.

Nickel‐Catalyzed Twofold Conjunctive Coupling via Philicity‐Alternating Radical Relay

Advanced Science, EarlyView.
Herein, we disclose a nickel‐catalyzed twofold conjunctive coupling that enables a four‐component assembly involving an activated alkene, a 1,3‐enyne, and both alkyl and aryl halides. Multiple C–C bonds are selectively constructed through a philicity‐alternating radical relay and the selective radical capture by the nickel catalyst.

Parâmetros produtivos, nutrição em fósforo e atividade foliar da fosfatase ácida no capim Braquiária cultivado em solução nutritiva

Boletim de Indústria Animal, 2013
Foi conduzido um experimento em solução nutritiva, em casa-de-vegetação, com capim-braquiária (Brachiaria decumbens Stapf), de janeiro a março de 1998. Foram utilizadas oito doses de fósforo (0,31; 0,93; 1,55; 3,1; 9,3; 15,5; 31,0 e 46,5 mg L-1). O delineamento foi o de blocos completos ao acaso, com quatro repetições.

Enhancing Chemical Stability and Molecular Selectivity of Porous Organic Cages via Core–Shell Polymer Coating

Advanced Science, EarlyView.
This study presents an interfacial method to fabricate POC@polymer core–shell nanostructures combining cage porosity with polymer robustness. Through chiral self‐assembly and non‐solvent‐induced surface polymerisation, uniform ∼20 nm polymer‐coated particles are produced.

m5C‐Modified tRF3b‐CysGCA‐23 Suppresses Bladder Cancer Malignancy by Repressing H3K18 Lactylation via Stabilizing RBM4

Advanced Science, EarlyView.
In this study, we identified an NSUN6‐dependent m5C‐modified tsRNA, m5C‐tRF3b CysGCA‐23 (mtRC), that is downregulated in BC and inversely correlated with disease progression. Mechanistically, mtRC suppresses BC malignancy by stabilizing RBM4, attenuating glycolysis, and thereby limiting H3K18 lactylation–mediated activation of IL1RAP and VASH2 ...

POU2F1 Promotes Chemoresistance in Colorectal Cancer Cells via Attenuates the MDR2 Degradation Mediated by PPP1R11 Lactylation

Advanced Science, EarlyView.
Schematic diagram of our study showing that highly expressed POU2F1 in colorectal cancer (CRC) can directly accelerate the cytosolic lactate export to decrease PPP1R11 lactylation at K59, thereby attenuating the E3 ligase enzyme activity and protein stability of PPP1R11, which inhibits the ubiquitination of MDR2 at K413 and K538 but increases the ...

Spatial Control Over Tether‐Tunable Coordination on Palladium for Divergent Synthesis of Bicyclo[n.1.0]alkanes via Oxidative Cyclopropanation of Enynes

Advanced Science, EarlyView.
We have developed a Pd‐catalyzed oxidative cyclopropanation of 1,n‐enynes employing cyclic diacyl peroxides as bifunctional reagents that serve as both tether‐tunable oxidants and spatially controlled dicarboxylate anions. ABSTRACT Bicyclo[n.1.0]alkanes are highly valuable scaffolds in drug discovery and synthetic chemistry.
