Atributos biológicos indicadores da qualidade do solo em pastagem cultivada e nativa no Pantanal Biological indicator attributes of soil quality under cultivated and natural pasture in the Pantanal wetlands

open access: yesPesquisa Agropecuária Brasileira, 2009
O objetivo deste trabalho foi avaliar as alterações nos atributos biológicos do solo, em razão da conversão floresta nativa pastagem cultivada e submissão de pastagens nativas a sistema pastejo contínuo, um Neossolo Quartzarênico, no Pantanal sul-mato ...

The effect of synthetic and bovine conjugated linoleic acid on energy balance : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Nutritional Science at Massey University, Palmerston North, New Zealand [PDF]

open access: yes, 1999
Conjugated linoleic acid (CLA) is biologically active and has altered body composition in experimental animals. Dietary supplementation with synthetic CLA reduced body fat in mice and rats in a number of studies.

On the slice genus of links

open access: yes, 2003
We define Casson-Gordon sigma-invariants for links and give a lower bound of the slice genus of a link in terms of these invariants. We study as an example a family of two component links of genus h and show that their slice genus is h, whereas the ...

Reduction in BACE1 decreases body weight, protects against diet-induced obesity and enhances insulin sensitivity in mice [PDF]

open access: yes, 2012
Insulin resistance and impaired glucose homoeostasis are important indicators of Type 2 diabetes and are early risk factors of AD (Alzheimer's disease).

Th17 cells favor migration and invasiveness of cervical cancer cells under hypoxia in an IGF2BP2‐dependent manner

open access: yesInternational Journal of Cancer, EarlyView.
What's New? Hypoxic regions and inflammatory Th17 cells in the tumor environment are both associated with poor prognosis in cervical cancer. However, synergistic mechanisms between hypoxia and Th17 cells remain elusive. This study demonstrated Th17–hypoxia‐driven mechanisms underlying cervical cancer progression.

Asymptotic analysis of noisy fitness maximization, applied to metabolism and growth

open access: yes, 2016
We consider a population dynamics model coupling cell growth to a diffusion in the space of metabolic phenotypes as it can be obtained from realistic constraints-based modelling.

Fetal size, gestational age, and cognitive performance at 5 years in term‐born children: Four national cohorts' study

open access: yesInternational Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective Fetal size and gestational age are essential factors to consider when determining the timing of delivery between mothers and obstetricians in term pregnancies. Previous studies have shown that both fetal size and gestational age have associations with cognitive or academic outcomes.

Spatial multi‐omics identifies a NOTCH3‐mediated capillary–mCAF crosstalk driving immune exclusion in hepatocellular carcinoma

open access: yesiMeta, EarlyView.
Spatial multi‐omics defines a DLL4–NOTCH3–driven capillary–mCAF axis orchestrating fibrotic remodeling and immune exclusion in hepatocellular carcinoma tumor cores, conferring immune checkpoint blockade resistance. Targeting stromal NOTCH3 disrupts this pro‐fibrotic niche, enhances T cell infiltration, and synergizes with anti‐PD‐1 therapy ...

Effect of Using the Food Quotient as a Proxy of the Respiratory Quotient in the Calculation of Energy Expenditure by the Doubly Labeled Water Method in Older Adults. [PDF]

open access: yesAm J Hum Biol
ABSTRACT Background and Aims Accurate measurement of total energy expenditure (TEE) is critical for maintaining energy balance and body weight. This study aimed to analyze differences in TEE assessed by the doubly labeled water method (DLW‐TEE), using food quotient (FQ) derived from self‐reported 24‐h dietary recalls, respiratory quotient measured by ...
