Pattern formation at cellular membranes by phosphorylation and dephosphorylation of proteins [PDF]

, 2016
We consider a classical model on activation of proteins, based in two reciprocal enzymatic biochemical reactions. The combination of phosphorylation and dephosphorylation reactions of proteins is a well established mechanism for protein activation in ...

Paraben Exposure in the General Taiwanese Population: Reference Values, Personal Care Products, and Cumulative Risk Assessment

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Parabens (parahydroxybenzoates), which are frequently used as preservatives in pharmaceuticals, foodstuffs, and personal care products, have recently attracted considerable attention due to their adverse health effects and endocrine‐disrupting properties.

Biochar‐Induced Shifts in Fungal Community Structure and Their Association With Soil Physical Properties in Degraded Soil From the Brazilian Semiarid

Land Degradation &Development, EarlyView.
ABSTRACT Soil degradation compromises ecosystem functioning. Biochar, a carbon‐rich amendment, has gained attention as a promising strategy to enhance soil structure and restore microbial balance. This study investigated the effects of two biochars, cashew bagasse biochar (CBB) and a co‐pyrolyzed biochar produced from sewage sludge and cashew pruning ...

Response of soil fungi and biological processes to crop residues in no-tillage system

Pesquisa Agropecuária Tropical, 2016
Soil management and crop rotation can directly affect the soil microbial community. This study aimed at determining soil quality indicators and soilborne fungi in a no-tillage system. A randomized blocks design, in a 3 × 2 factorial arrangement, was used.

Medication Knowledge of Patients with Parkinson's Disease: Strengths and Gaps

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Effective drug treatment of motor and non‐motor symptoms in Parkinson's disease (PD) often requires the administration of several anti‐Parkinson drugs in complex treatment regimens. The successful autonomous application of drugs places high demands on therapy adherence, which in turn relies on sufficient medication knowledge ...

Altered Cerebrospinal Fluid Tryptophan–Kynurenine Pathway Metabolism in Multiple System Atrophy

Movement Disorders, EarlyView.
Abstract Background Alterations in tryptophan–kynurenine (TRP‐KYN) metabolism, which is associated with neuroinflammation, remain unclear in multiple system atrophy (MSA). Objective The aim was to investigate cerebrospinal fluid (CSF) TRP metabolites in MSA and their associations with other biomarkers.

DOC trial: diversity and metabolic effiency of microbial communities in organic and conventional soils [PDF]

, 2000
Soil microbiota are favoured by organic farming systems. Moreover they were found to need less energy fore their maintenance. The diversity of microbial functions was also increased. Our results support the hypothesis that diverse populations make better
