Allopurinol hypersensitivity is primarily mediated by dose-dependent oxypurinol-specific T cell response [PDF]

, 2013
BACKGROUND Allopurinol is a main cause of severe cutaneous adverse reactions (SCAR). How allopurinol induces hypersensitivity remains unknown. Pre-disposing factors are the presence of the HLA-B*58:01 allele, renal failure and possibly the dose taken.

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

FEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

Challenges of drug resistance in the management of pancreatic cancer [PDF]

, 2010
The current treatment of choice for metastatic pancreatic cancer involves single agent gemcitabine or combination of gemcitabine with capecitabine and erlotinib (tyrosine kinase inhibitor).

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

FEBS Letters, EarlyView.
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

Optimal designs for dose-response models with restricted design spaces [PDF]

In dose response studies, the dose range is often restricted due to concerns over drug toxicity and/or efficacy. We present restricted and unrestricted interval locally optimal designs with respect to a very general class of optimality criteria for ...

Efficacy of high-dose vs. low-dose intravitreal ganciclovir for cytomegalovirus retinitis: a systematic review and meta-analysis [PDF]

Journal of Yeungnam Medical Science
Background Intravitreal ganciclovir is widely used to achieve effective local antiviral concentrations for cytomegalovirus (CMV) retinitis; however, to our knowledge, standardized dosing strategies have not been established, and the reported regimens ...

Modelling stem cell differentiation related processes—A practical overview for biologists

FEBS Letters, EarlyView.
Stem cell differentiation is complex and difficult to control experimentally. This review introduces suitable computational modelling approaches that can support stem cell research, from mechanistic ODE and abstract models to multiscale and deep learning methods.

Practical considerations for optimal designs in clinical dose finding studies [PDF]

Determining an adequate dose level for a drug and, more broadly, characterizing its dose response relationship, are key objectives in the clinical development of any medicinal drug. If the dose is set too high, safety and tolerability problems are likely

Open label, dose escalation trial of creatine monohydrate in pregnancy

Journal of the International Society of Sports Nutrition
Background Preclinical data demonstrates that creatine supplementation during pregnancy supports maternal and fetal energy homeostasis through periods of hypoxia, but its use in human pregnancy remains unexplored.

Are plasma drug concentrations still necessary? Rethinking the pharmacokinetic link in dose–response relationships

Frontiers in Pharmacology
Plasma drug concentrations have historically played a central role in pharmacology, serving as a measurable intermediary between administered dose and clinical response. This model, linking Dose, Concentration and Effect, underpins therapeutic drug monitoring, pharmacokinetic/pharmacodynamic (PK/PD) modeling, and regulatory evaluation.
