Inflammatory Bowel Disease Is Associated With an Increased Risk of End‐Stage Renal Disease: A Population‐Based Cohort Study

open access: yesAlimentary Pharmacology &Therapeutics, EarlyView.
In a retrospective population‐based cohort study using the University of Manitoba IBD Epidemiology Database, persons with IBD have an increased risk of ESRD by nearly 50%, with CD showing greater risk than UC. Bowel surgery, allopurinol use and oral steroid therapy are important predictors, emphasising the necessity of careful renal monitoring in IBD ...

Métodos para análise de ácido clorogênico

open access: yesQuímica Nova, 2004
This paper describes the analytical methods for determination of total chlorogenic acid (CGA) and their individual isomers. Spectrofotometric methods are adequate for total CGA analysis in green coffee but they can provide inflated results for coffee ...

Non‐canonical PKG1 regulation in cardiovascular health and disease

open access: yesBritish Journal of Pharmacology, EarlyView.
It is well established that the cyclic GMP‐dependent protein kinase I (PKG1) is canonically activated by cyclic guanosine monophosphate (cGMP), enabling its regulation of vascular tone, cardiac function and smooth muscle homeostasis. However, diverse non‐canonical stimuli of PKG1 have also been identified.

The discovery and development of ensifentrine: A novel inhaled dual PDE3/4 inhibitor having ‘bifunctional’ bronchodilator and anti‐inflammatory activity

open access: yesBritish Journal of Pharmacology, EarlyView.
Abstract Ensifentrine (formerly called RPL 554) is a novel, first in class, inhaled bifunctional dual PDE3/4 inhibitor for the treatment of chronic respiratory diseases. Ensifentrine exhibits both bronchodilation via PDE3 inhibition and anti‐inflammatory activity via PDE4 inhibition.

Ocular Manifestations of Metabolic Syndrome: A Systemic Vascular Phenotype

open access: yesDiabetes, Obesity and Metabolism, EarlyView.
ABSTRACT Context Metabolic syndrome (MetS) is defined by central obesity, insulin resistance, hypertension and dyslipidemia. MetS affects over one‐third of US adults. Beyond its cardiovascular burden, MetS has clinically relevant associations with ocular health and may contribute to a systemic vascular and neuro‐metabolic phenotype involving the retina,

Tyrosine residues at the substrate binding site in human NQO1 homodimer: Protein conformational dynamics and optimization of substrate binding geometry

open access: yesThe FEBS Journal, EarlyView.
Human NAD(P)H:quinone oxidoreductase 1 is a homodimeric flavoenzyme crucial for redox metabolism and linked to significant health issues. Point mutations at Tyr126 and Tyr128 demonstrate their essential roles in optimizing substrate binding geometry for catalysis, as well as in half‐site reactivity and conformational dynamics during the enzyme's ...

Transgenic selection and underlying mechanisms in apicomplexan parasites

open access: yesThe FEBS Journal, EarlyView.
Transgenic selection markers have driven genetic engineering in apicomplexans, enabling precise, iterative experiments. This review discusses mechanistic details of drug selection markers, strategies for marker recycling, and practical considerations for several clinically relevant parasites.
