Utilization of the pericapsular nerve group block in preoperative rehabilitation of patients with femoral neck fractures -a case series- [PDF]

open access: yesKorean Journal of Anesthesiology
Background Elderly patients with femoral neck fractures, particularly those with severe comorbidities or living in regions with limited medical resources, may experience delays in surgical treatment.

Increasing Robustness of the Anesthesia Process from Difference Patient's Delay Using a State-Space Model Predictive Controller [PDF]

open access: yesProcedia Engineering 15 (2011) 928-932, 2013
The process of anesthesia is nonlinear with time delay and also there are some constraints which have to be considered in calculating administrative drug dosage. We present an Extended Kalman Filter (EKF) observer to estimate drug concentration in the patient's body and use this estimation in a state-space based Model of Predictive Controller (MPC) for

The effects of repetitive electric cardiac stimulation in dogs with normal hearts, complete heart block and experimental cardiac arrest [PDF]

open access: yes, 1955
Direct cardiac stimulation was conducted in the open chest. In normal animals, auricular stimulation at frequencies faster than the spontaneous rate caused little change in vascular pressures or cardiac output.

COMBINED ANESTHESIA BY SEVOFLURANE AND ROPIVACAINE IN ELDERLY PATIENTS WITH DIFFERENT REACTIVITY OF THE CARDIOVASCULAR AND RESPIRATORY SYSTEMS

open access: yesКубанский научный медицинский вестник, 2017
The goal of the work was to evaluate anesthesia according to the central hemodynamic, oxygen, acid-base, temperature homeostasis, neuromuscular conduction monitoring the depth of anesthesia and recovery postanesthesia consciousness.

Interacting Turing-Hopf Instabilities Drive Symmetry-Breaking Transitions in a Mean-Field Model of the Cortex: A Mechanism for the Slow Oscillation [PDF]

open access: yes, 2013
Electrical recordings of brain activity during the transition from wake to anesthetic coma show temporal and spectral alterations that are correlated with gross changes in the underlying brain state. Entry into anesthetic unconsciousness is signposted by

Ion channel function of polycystin‐2/polycystin‐1 heteromer revealed by structure‐guided mutagenesis

open access: yesFEBS Letters, EarlyView.
Mutations in polycystin‐1 (PC1) or polycystin‐2 (PC2) cause autosomal‐dominant polycystic kidney disease (ADPKD). We generated a novel gain‐of‐function PC2/PC1 heteromeric ion channel by mutating pore‐blocking residues. Moreover, we demonstrated that PC2 will preferentially assemble with PC1 to form heteromeric complexes when PC1 is co‐expressed ...

Membrane Nanodomains Homeostasis During Propofol Anesthesia as Function of Dosage and Temperature [PDF]

open access: yes, 2020
Some anesthetics bind and potentiate gamma-aminobutyric-acid-type receptors, but no universal mechanism for general anesthesia is known. Furthermore, often encountered complications such as anesthesia induced amnesia are not understood. General anesthetics are hydrophobic molecules easily dissolving into lipid bilayers.

SENSORY REGRESSION TIME FROM SUBARACHNOID BLOCK WITH HYPERBARIC 0.75% BUPIVACAINE IN THE OBESE PATIENT [PDF]

open access: yes, 1989
The purpose of this study was to determine if obese patients have a different sensory regression time from subarachnoid block than non-obese patients using hyperbaric 0.75% bupivacaine. A quasi-experimental design was used. Twenty patients were separated

Intravenous infusion of magnesium sulfate and its effect on horses with trigeminal-mediated headshaking. [PDF]

open access: yes, 2019
BackgroundTrigeminal-mediated headshaking results from low-threshold firing of the trigeminal nerve resulting in apparent facial pain. Magnesium may have neuroprotective effects on nerve firing that potentially dampen signs of neuropathic pain.

Subpar reporting of pre‐analytical variables in RNA‐focused blood plasma studies

open access: yesMolecular Oncology, EarlyView.
Pre‐analytical variables strongly influence the analysis of extracellular RNA (cell‐free RNA; exRNA) derived from blood plasma. Their reporting is essential to allow interpretation and replication of results. By evaluating 200 exRNA studies, we pinpoint a lack of reporting pre‐analytical variables associated with blood collection, plasma preparation ...
