In vitro and in vivo metabolism profiles of cathinone and pseudoephedrine: Discrimination between khat and pseudoephedrine uses

open access: yesJournal of Forensic Sciences, EarlyView.
Abstract In the present study, the metabolism of khat (Catha edulis) and pseudoephedrine was compared with the aim of identifying objective criteria that could be used to discriminate between them for forensic and doping‐control purposes. An in vitro study using human liver microsomes and an in vivo study using rat urine were performed under harmonized

Atrial Fibrillation and Hyperthyroidism [PDF]

open access: yes, 2005
Atrial fibrillation occurs in 10 – 15% of patients with hyperthyroidism. Low serum thyrotropin concentration is an independent risk factor for atrial fibrillation. Thyroid hormone contributes to arrythmogenic activity by altering the electrophysiological

Impact of barometric pressure on blood pressure during dialysis: Introducing intradialytic time‐averaged cumulative systolic blood pressure (TACsBP‐inD) as a new metric

open access: yesTherapeutic Apheresis and Dialysis, Volume 29, Issue 3, Page 525-534, June 2025.
Abstract Background Blood pressure is a crucial risk factor for hemodialysis patients, but the specific impact of weather factors, particularly barometric pressure, on blood pressure remains unclear. This study aims to examine the relationship between barometric pressure and blood pressure in hemodialysis patients. Methods We conducted a single‐center,

Cardiovascular Plasticity and Adaptation of High‐Altitude Birds and Mammals

open access: yesIntegrative Zoology, EarlyView.
This schematic depicts the cardiovascular adaptations of mammals and birds to high‐altitude hypoxia. It highlights key phenotypic changes in oxygen transport and cardiac responses, driven by molecular mechanisms including transcriptional regulation and genetic modifications.

Heteroreceptor complexes and their allosteric receptor-receptor interactions in the central nervous system. Focus on examples from Dopamine D2 and Serotonin 5-HT1a receptors [PDF]

open access: yes, 2018
GPCR interacting proteins (specially β- arrestin) and their receptor-protein interactions are also covered but their interactions with the allosteric receptor-receptor interactions in heteroreceptor complexes remain to be elucidated.

Effect of Intramuscular Adrenaline on Histamine‐Induced Hypotension: A Randomised Placebo‐Controlled Pilot Trial

open access: yesAllergy, EarlyView.
Histamine infusions induce reproducible severe hypotension. Intramuscular adrenaline showed ‘supposedly therapeutic’ plasma concentrations but did not produce a sustained clinically relevant improvement in shock in the majority of recipients. These findings question adrenaline pharmacokinetic surrogate thresholds and support the need for faster and ...

Imipramine Increases Norepinephrine and Serotonin in the Salivary Glands of Rats

open access: yesBiology
Xerostomia induced by antidepressants such as imipramine has long been thought to be due to their anticholinergic effects. However, even antidepressants with low anticholinergic effects may have a high incidence of xerostomia.

Efficacy and safety of different vasopressor infusions on feto‐maternal outcomes in normotensive patients undergoing caesarean delivery: a systematic review and network meta‐analysis of randomised controlled trials

open access: yesAnaesthesia, EarlyView.
Summary Introduction Phenylephrine infusion is widely endorsed by guidelines as the preferred prophylactic drug for spinal hypotension in patients undergoing caesarean delivery; however, clinical practice continues to show marked variability in the selection of vasopressor drugs.
