Fragmented QRS as a risk marker for the occurrence of ventricular fibrillation in patients with variant angina

open access: yesAnnals of Noninvasive Electrocardiology, Volume 27, Issue 3, May 2022., 2022
Abstract Background Variant angina (VA) is caused by reversible coronary artery spasm, which is characterized by chest pain with ST‐segment elevations on standard 12‐lead electrocardiogram (ECG) at rest. Ventricular fibrillation (VF) is often caused by VA attack, but the risk stratification is not well understood.

Admission serum potassium levels and prognosis of vasospastic angina

open access: yesScientific Reports, 2021
Hypokalemia is a common electrolyte disturbance and is related to poor prognosis in patients with cardiovascular disease. However, the role of hypokalemia in patients with vasospastic angina (VSA) has not yet been studied. The present study enrolled 1454

Microbiological and mycotoxicological analyses of processed cereal‐based complementary foods for infants and young children from the German market

open access: yesJournal of Food Science, Volume 87, Issue 4, Page 1810-1822, April 2022., 2022
Abstract This study investigated several food safety criteria in 38 different commercial products of processed cereal‐based foods (PCF) from the German market. Microbiological assessment, followed by 16S RNA gene sequencing of suspect colonies, included aerobic mesophilic bacteria, moulds, Enterobacteriaceae, Cronobacter spp., and presumptive Bacillus ...

The medication violations in racehorses at Louisiana racetracks from 2016 to 2020

open access: yesVeterinary Medicine and Science, Volume 8, Issue 2, Page 553-560, March 2022., 2022
This study reports the most common medication violations in racehorses at four major racetracks in Louisiana between 2016 and 2020. The most frequent violations included the overages (concentrations of permitted medications equal to or exceeding the set threshold) of clenbuterol (165 violations), non‐steroidal anti‐inflammatory drugs (NSAIDs) such as ...

Blunted heart rate recovery is associated with coronary artery spasm in patients with suspected vasospastic angina

open access: yesClinical Hypertension, 2017
Background Autonomic nervous system activity has been shown to be altered in patients with vasospastic angina (VA). Heart rate recovery (HRR) is a simple, non-invasive measurement of autonomic nervous system dysfunction.

Alkaloid Contents in Epichloë Endophyte-Infected Elymus tangutorum Sampled along an Elevation Gradient on the Qinghai-Tibetan Plateau

open access: yesAgronomy, 2020
Alkaloids produced by endophytic fungi can have an important influence on agricultural ecology, and can often be affected by climatic factors. At present, there are no studies that have assessed the relationship between alkaloid production and elevation ...
