Behavioral and pharmacological characterization of a mouse model of palatable diet alternation [PDF]

open access: yes, 2017
Obesity and eating disorders represent a severe problem in Western societies. Both the increased availability of highly palatable foods and dieting are major risk factors contributing to the epidemic disorders of feeding. The purpose of this study was to

Disinhibition of hippocampal CA3 neurons induced by suppression of an adenosine A1 receptor-mediated inhibitory tonus: Pre- and postsynaptic components [PDF]

open access: yes, 1993
Intracellular recordings were performed on hippocampal CA3 neuronsin vitro to investigate the inhibitory tonus generated by endogenously produced adenosine in this brain region.

Impacto de herbicidas em isolados de Trichoderma spp. Impact of herbicides on strains of Trichoderma spp.

open access: yesPlanta Daninha, 2013
O uso de microrganismos é uma alternativa para o controle de doenças em plantas. Todavia, é prudente verificar a interação desse com os demais métodos de controle empregados em determinada cultura.

Turbulent mixing controls fixation of growing antagonistic populations [PDF]

open access: yesPNAS 122 (7) e2417075122 (2025)
Unlike coffee and cream that homogenize when stirred, growing micro-organisms (e.g., bacteria, baker's yeast) can actively kill each other and avoid mixing. How do such antagonistic interactions impact the growth and survival of competing strains, while being spatially advected by turbulent flows? By using numerical simulations of a continuum model, we

Autophagy in cancer and protein conformational disorders

open access: yesFEBS Letters, EarlyView.
Autophagy plays a crucial role in numerous biological processes, including protein and organelle quality control, development, immunity, and metabolism. Hence, dysregulation or mutations in autophagy‐related genes have been implicated in a wide range of human diseases.

Galanin decreases NPYY1R internalization and β- Arrestin2 recruitment [PDF]

open access: yes, 2015
We have recently described a Galanin receptor 2(GALR2) and Neuropeptide Y Y1 receptor(NPYY1R) interaction at behavioural, cellular and receptor levels through GALR2/NPYY1R heterodimers.

Structure of the BTB Domain of Keap1 and Its Interaction with the Triterpenoid Antagonist CDDO

open access: yesPLoS ONE, 2014
The protein Keap1 is central to the regulation of the Nrf2-mediated cytoprotective response, and is increasingly recognized as an important target for therapeutic intervention in a range of diseases involving excessive oxidative stress and inflammation ...

A stepwise emergence of evolution in the RNA world

open access: yesFEBS Letters, EarlyView.
How did biological evolution emerge from chemical reactions? This perspective proposes a gradual scenario of self‐organization among RNA molecules, where catalytic feedback on random mixtures plays the central role. Short oligomers cross‐ligate, and self‐assembly enables heritable variations. An event of template‐externalization marks the transition to

What Is Antagonistic Pleiotropy? [PDF]

open access: yesBiochemistry (Moscow), 2018
Antagonistic Pleiotropy has been the dominant theory for evolution of aging since it was first proposed 60 years ago. Indeed, examples of pleiotropy have been observed, but there are also many examples of mutations that lead to longer lifespan without apparent cost.
