Exercise during 14 days of head down tilt bedrest attenuates motor unit impairments in older humans

open access: yesExperimental Physiology, EarlyView.
Abstract Head‐down tilt bedrest (HDBR) models the effects of mechanical unloading on neuromuscular function. The efficacy of exercise in preserving motor unit (MU) function in older adults during HDBR remains unclear. This study investigated the effects of 14‐day HDBR on MU properties in older adults and the protective role of exercise.

The Role of Barbiturates for Alcohol Withdrawal Syndrome.

open access: yes, 2016
BACKGROUND: Benzodiazepine-resistant cases of alcohol withdrawal syndrome are common, and therefore alternate treatments are needed. OBJECTIVE: Our aim was to conduct a systematic review of published reports on the use of barbiturates for alcohol ...

Electromechanical modelling and simulation of human‐induced pluripotent stem cell‐derived cardiomyocytes predict drug‐induced contractility effects

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend A study described in this paper describes a new tool for hiPSC‐CM electromechanical behaviour simulations using mathematical modelling. The model enables in silico assays making drug testing quick, comprehensive and accurate. New hiPSC‐CM models can be used as a platform to integrate in vitro and in silico findings.

Barbiturates are selective antagonists at A\(_1\) adenosine receptors

open access: yes, 1985
Barbiturates in pharmacologically relevant . concentrations inhibit binding of (R)-\(N^6\)-phenylisopropyl[\(^3\)H]adenosine ([\(^3\)H]PIA) to solubilized A\(_1\) adenosine receptors in a concentration-dependent, stereospecific, and competitive manner. K\

Synthesis, X-Ray Crystal Structures, Biological Evaluation, and Molecular Docking Studies of a Series of Barbiturate Derivatives

open access: yesJournal of Chemistry, 2016
A series of barbiturates derivatives synthesized and screened for different set of bioassays are described. The molecular structures of compounds 5a, 5d, and 5f were solved by single-crystal X-ray diffraction techniques. The results of bioassay show that

Distinctive neurophysiological correlates of sound onset and offset perception in humans

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Electroencephalography (EEG) recordings were obtained from participants listening to successive pairs of 1‐2 s noises in a silent background (Study 1) or successive pairs 1‐2 s silent gaps in a noise background (Study 2). Participants heard the same stimuli in the context of either a duration discrimination task (identifying ...

Analysis of Barbiturates by GC/MS, HPLC and Chemical Ionization

open access: yes, 2012
Barbiturates are derivatives of barbituric acid. They act as central nervous depressants. These drugs are frequently used as sedatives or anesthetics. It is a simple and reproducible method for the analysis of barbiturates.

Multicomponent, One-Pot Sequential Synthesis of 1,3,5- and 1,3,5,5-Substituted Barbiturates

open access: yes, 2016
Carbodiimides and malonic acid monoethylesters readily react to afford N-acylurea derivatives that could be cyclized in situ by addition of a suitable base.

Association Between Spinal Manipulation, Butalbital Prescription, and Medication Overuse Headache in Adults With Tension‐Type Headache: Retrospective Cohort Study

open access: yesHealth Science Reports
Background and Aims Butalbital is an acute headache medication commonly prescribed for tension‐type headache (TTH), although discouraged by guidelines due to a risk of medication overuse headache (MOH).

Drug Critical Limits for Urgent Physician Notification

open access: yesClinical Pharmacology &Therapeutics, Volume 120, Issue 1, Page 178-192, July 2026.
Critical limits represent quantitative decision thresholds for drugs that require immediate clinician notification and potential life‐saving intervention. United States hospitals lack a national standard for drug critical limits. We collected critical limits from 417 US hospitals across all 50 states and Washington, D.C.; of these, 411 maintained drug ...
