Sevoflurane provides better haemodynamic stability than propofol during right ventricular ischaemia-reperfusion

OBJECTIVES: To assess whether sevoflurane provides better haemodynamic stability than propofol in acute right ventricular (RV) ischaemia-reperfusion. METHODS: Open-chest pigs (mean ± standard deviation, 68.8 ± 4.2 kg) anaesthetized with sevoflurane (n = 6) or propofol (n = 6) underwent 60 min of RV free wall ischaemia and 150 min of reperfusion. Haemodynamic parameters and blood flow in the 3 majo

Discovery of Procognitive Antipsychotics by Combining Muscarinic M1 Receptor Structure-Activity Relationship with Systems Response Profiles in Zebrafish Larvae

Current antipsychotic drugs are notably ineffective at addressing the cognitive deficits associated with schizophrenia. N-Desmethylclozapine (NDMC), the major metabolite of clozapine, displays muscarinic M1 receptor (M1) agonism, an activity associated with improvement in cognitive functioning. Preclinical and clinical data support that M1 agonism may be a desired activity in antipsychotic drugs.

Pancreatic islet uptake of sucrose and urea in the absence and presence of glucose

Microdissected pancreatic islets of ob/ob mice were used to study whether glucose induced insulin release is associated with changes of the apparent extracellular space. Glucose at a concentration of 20 mM had no measurable effect on the islet uptake of sucrose and urea. In the presence of these space markers glucose stimulated insulin release significantly. The results do not invalidate the hypot

Iodoacetamide-induced sensitization of the pancreatic beta-cells to glucose stimulation.

At a glucose concentration of 3mm or less, iodoacetamide had no effect on the release of insulin from microdissected pancreatic islets of ob/ob-mice. At higher glucose concentrations, iodoacetamide exerted both an initial stimulatory and a subsequent inhibitory action. When islets were perifused with 1mm-iodoacetamide and 17mm-glucose the inhibitory action predominated after about 15min of transie

Computation of Biobjective /Bidisciplinary optimization

It is well known that a modern fighter should have high aerodynamic performance, i.e., high lift (C L) and low drag (C D), high C L/C D at subsonic speed and low drag at supersonic speed, etc. However, stealthy performance has also become one of the basic requirements to a modern fighter. So the task of a designer today is to shape the aircraft with not only the maximum aerodynamic efficiency but

Physical mechanism on exciton-plasmon coupling revealed by femtosecond pump-probe transient absorption spectroscopy.

The unclear mechanism of exciton-plasmon coupling interaction in monolayer MoS2-Ag nanoparticles hybrid, as a longstanding target in molecular nanotechnology and catalysis, is systemically investigated with transmission spectra and femtosecond pump-probe transient absorption spectroscopy in this paper. The properties of exciton in monolayer MoS2 are strongly enhanced due to the local surface plasm

Children with Hirschsprung's Disease and Syndromes with Cognitive Dysfunction : Manifestations, Treatment, and Outcomes

Introduction To assess differences in initial symptoms, treatments, and bowel function between children with Hirschsprung's disease (HD) with or without a cognitive dysfunction (CD). Materials and Methods The study included children with HD who underwent transanal endorectal pull-through. A retrospective chart review was performed to collect data on patient characteristics, diagnosis, and treatmen

Tumor genetic heterogeneity analysis of chronic sun-damaged melanoma

Chronic sun-damaged (CSD) melanoma represents 10%-20% of cutaneous melanomas and is characterized by infrequent BRAF V600E mutations and high mutational load. However, the order of genetic events or the extent of intra-tumor heterogeneity (ITH) in CSDhigh melanoma is still unknown. Ultra-deep targeted sequencing of 40 cancer-associated genes was performed in 72 in situ or invasive CMM, including 2

Rationale and design of the AFFIRM-AHF trial : a randomised, double-blind, placebo-controlled trial comparing the effect of intravenous ferric carboxymaltose on hospitalisations and mortality in iron-deficient patients admitted for acute heart failure

Aims: Iron deficiency (ID) is a common co-morbidity in heart failure (HF), associated with impaired functional capacity, poor quality of life and increased morbidity and mortality. Treatment with intravenous (i.v.) ferric carboxymaltose (FCM) has shown improvements in functional capacity, symptoms and quality of life in stable HF patients with reduced ejection fraction. The effect of i.v. iron sup

Uncovering human METTL12 as a mitochondrial methyltransferase that modulates citrate synthase activity through metabolite-sensitive lysine methylation

Lysine methylation is an important and much-studied posttranslational modification of nuclear and cytosolic proteins but is present also in mitochondria. However, the responsible mitochondrial lysine-specific methyltransferases (KMTs) remain largely elusive. Here, we investigated METTL12, a mitochondrial human S-adenosylmethionine (AdoMet)-dependent methyltransferase and found it to methylate a si

Four Dimensions of Criticism Against Gender-Fair Language

The gender-neutral third-person pronoun singular hen was recently introduced in Swedish as a complement to she (hon) and he (han). The initiative to add hen initially received strong criticism. In the present study, we analyzed 208 arguments from 168 participants with critical attitudes toward hen. We used Blaubergs’ (1980) and Parks and Roberton’s (1998) taxonomies of critical arguments against p
