Forças de transformação do ecossistema amazônico

open access: yesEstudos Avançados, 2005
NOS 470 anos iniciais da colonização da Amazônia brasileira, apenas 1% da área foi desmatada. Porém, nos últimos 35 anos (1970-2005) o desmatamento já atinge 17% da região e a população aumentou de dois milhões para mais de 20 milhões de habitantes. Hoje,

Gut Microbiota and Colonization Resistance against Bacterial Enteric Infection

open access: yesMicrobiology and Molecular Biology Reviews, 2019
The gut microbiome is critical in providing resistance against colonization by exogenous microorganisms. The mechanisms via which the gut microbiota provide colonization resistance (CR) have not been fully elucidated, but they include secretion of ...

Cis‐regulatory and long noncoding RNA alterations in breast cancer – current insights, biomarker utility, and the critical need for functional validation

open access: yesMolecular Oncology, EarlyView.
The noncoding region of the genome plays a key role in regulating gene expression, and mutations within these regions are capable of altering it. Researchers have identified multiple functional noncoding mutations associated with increased cancer risk in the genome of breast cancer patients.

Strength through diversity: how cancers thrive when clones cooperate

open access: yesMolecular Oncology, EarlyView.
Intratumor heterogeneity can offer direct benefits to the tumor through cooperation between different clones. In this review, Kuiken et al. discuss existing evidence for clonal cooperativity to identify overarching principles, and highlight how novel technological developments could address remaining open questions.

A Gallus gallus Model for Determining Infectivity of Zoonotic Campylobacter

open access: yesFrontiers in Microbiology, 2019
To better understand public health implications of waterfowl as reservoirs for zoonotic sources of Campylobacter in recreational waters, we developed a Gallus gallus (chick) model of infection to assess the pathogenicity of environmental isolates of ...

LDAcoop: Integrating non‐linear population dynamics into the analysis of clonogenic growth in vitro

open access: yesMolecular Oncology, EarlyView.
Limiting dilution assays (LDAs) quantify clonogenic growth by seeding serial dilutions of cells and scoring wells for colony formation. The fraction of negative wells is plotted against cells seeded and analyzed using the non‐linear modeling of LDAcoop.
