Rpt2 proteasome subunit reduction causes Parkinson's disease like symptoms in Drosophila

IBRO Reports, 2020
The dysfunction of the proteasome-ubiquitin system is commonly reported in several neurodegenerative diseases. Post mortem samples of brains of patients with Parkinson´s disease present cytoplasmic inclusions that are rich in proteins such as ubiquitin ...

Introduced dung beetles suppress methane emissions from cattle dung and alter the temporal dynamics of greenhouse gas flux Los escarabajos peloteros introducidos suprimen las emisiones de metano del estiércol de ganado y alteran la dinámica temporal del flujo de gases de efecto invernadero Besouros coprófagos introduzidos suprimem as emissões de metano do esterco bovino e alteram a dinâmica temporal do fluxo de gases de efeito estufa

Ecological Entomology, EarlyView.
Dung beetles suppressed cumulative methane flux from cattle dung by 85% and reduced total greenhouse gas emissions by 18%. Beetle activity accelerated initial CO2 release but did not alter total cumulative flux. N2O and NH3 fluxes were transient and not consistently driven by beetle presence.

Microencapsulation of bioactive compounds from peanut residues: stability study and application in yogurt

Journal of the Science of Food and Agriculture, Volume 106, Issue 11, Page 6472-6484, 30 August 2026.
Abstract BACKGROUND Peanut skin, a byproduct of peanut processing, is a rich source of phenolic compounds (520.65 mgGAE (100 g)−1 d.b.) with strong antioxidant capacity, but which remains underutilized. The direct incorporation of phenolic extracts into dairy products is challenging, due to their instability during processing and storage and possible ...

Nicotine suppresses Parkinson’s disease like phenotypes induced by Synphilin-1 overexpression in Drosophila melanogaster by increasing tyrosine hydroxylase and dopamine levels

Scientific Reports, 2021
It has been observed that there is a lower Parkinson’s disease (PD) incidence in tobacco users. Nicotine is a cholinergic agonist and is the principal psychoactive compound in tobacco linked to cigarette addiction.

Biobased Polyurethane Films Based on Andiroba (Carapa guianensis) and Buriti (Mauritia flexuosa) Oil Polyols

Journal of Applied Polymer Science, Volume 143, Issue 30, August 10, 2026.
Polyurethane films were prepared from andiroba (Carapa guianensis) and buriti (Mauritia flexuosa) oil‐derived polyols, emphasizing their potential as bio‐based materials. UV–Vis analysis indicates the retention of carotenoid‐related chromophoric features within the polymer matrix.

Development and Characterization of ZnO‐Filled and Maleic Anhydride‐Compatibilized PP/SEBS Blends for 3D‐Printing Filaments

Journal of Applied Polymer Science, Volume 143, Issue 29, August 5, 2026.
PP/SEBS/MA/ZnO filaments produced by bench‐top single‐screw extrusion show refined morphology, increased crystallinity, improved thermal robustness, and preliminary FFF printability, demonstrating a practical route for functional filament development. ABSTRACT Currently, single‐screw extrusion offers a versatile and accessible route to produce polymer ...

Synthesis and Characterization of Novel Silylated Sm3+ and Eu3+ Complexes Incorporated Into Mesoporous Silica Nanoparticles

European Journal of Inorganic Chemistry, Volume 29, Issue 19, 2 July 2026.
The strategy of incorporating the Eu(tta‐Si)3(phen) and Sm(tta‐Si)3(phen)2 complexes prevented leaching of the complexes and preserved their intrinsic optical properties. Preliminary studies of silylated Ln3+ complexes and nanoparticles loaded with these complexes demonstrated cytotoxicity against cancer cells, with minimal cytotoxic effect on nontumor
