Association of Preoperative Basal Inflammatory State, Measured by Plasma suPAR Levels, with Intraoperative Sublingual Microvascular Perfusion in Patients Undergoing Major Non-Cardiac Surgery
(2022)It remains unknown whether chronic systemic inflammation is associated with impaired microvascular perfusion during surgery. We evaluated the association between the preoperative basal inflammatory state, measured by plasma ... -
Baseline Values and Kinetics of IL-6, Procalcitonin, and TNF- α in Landrace-Large White Swine Anesthetized with Propofol-Based Total Intravenous Anesthesia
(2021)The baseline levels of various inflammatory mediators and their changes during anesthesia in swine are not known. The aim of this animal study was to measure the baseline values and kinetics of interleukin-6, procalcitonin, ... -
The contribution of a collagen patch coated with fibrin glue in sealing upper gastrointestinal defects: An experimental study
(2021)Background/Aim: We aimed to evaluate the safety and efficacy of sealing primary upper gastrointestinal (GI) perforations with a collagen patch coated with fibrin glue (Tachosil®). Materials and Methods: Thirty New Zealand ... -
Crocins, the bioactive components of crocus sativus l., counteract the disrupting effects of anesthetic ketamine on memory in rats
(2021)Consistent experimental evidence suggests that anesthetic doses of the non-competitive N-methyl-D-aspartate (NMDA) receptor antagonist ketamine cause severe memory impairments in rodents. Crocins are among the various ... -
Determinants of venous return in steady-state physiology and asphyxia-induced circulatory shock and arrest: an experimental study
(2022)Background: Mean circulatory filling pressure (Pmcf) provides information on stressed volume and is crucial for maintaining venous return. This study investigated the Pmcf and other determinants of venous return in dysrhythmic ... -
Development and Testing of a Novel Anaesthesia Induction/Ventilation Protocol for Patients With Cardiogenic Shock Complicating Acute Myocardial Infarction
(2018)Background: Cardiogenic shock is a life-threatening condition and patients might require rapid sequence induction (RSI) and mechanical ventilation. In this study, we evaluated a new RSI/mechanical ventilation protocol in ... -
Do trabecular metal and cancellous titanium implants reduce the risk of late haematogenous infection? An experimental study in rabbits
(2021)Aim: This study evaluated the late resistance to haematogenous contamination by microbial pathogens of implants and bone-implant interface and the development of late clinical infection when cementless components with ... -
Effects of Anesthetic Ketamine on Anxiety-Like Behaviour in Rats
(2019)There is scarce information regarding the effects of anesthetic doses of the non-competitive N-methyl-d-aspartate receptor antagonist ketamine on anxiety. The current study evaluated the acute effects of intraperitoneally ... -
Effects of sub-anesthetic doses of ketamine on rats' spatial and non-spatial recognition memory
(2008)There are experimental evidences indicating that the non-competitive N-methyl-D-aspartate (NMDA) receptor antagonist ketamine impairs cognition and produces a series of schizophrenia-like symptoms in rodents (hyperactivity, ... -
Effects of the inducible nitric oxide synthase inhibitor aminoguanidine in two different rat models of schizophrenia
(2016)Several lines evidence indicate that the non-competitive N-methyl-d-aspartate (NMDA) receptor antagonist ketamine and the mixed dopamine (DA) D1/D2 receptor agonist apomorphine induce schizophrenia-like symptoms in rodents, ... -
Effects of the Nitric Oxide Synthase Inhibitor L-NAME on Recognition and Spatial Memory Deficits Produced by Different NMDA Receptor Antagonists in the Rat
(2010)There is consistent experimental evidence that noncompetitive antagonists of the N-methyl-D-aspartate (NMDA) receptor, such as ketamine, MK-801, and phencyclidine (PCP), impair cognition and produce psychotomimetic effects ... -
Flumazenil but not bicuculline counteract the impairing effects of anesthetic ketamine on recognition memory in rats. Evidence for a functional interaction between the GABA A -benzodiazepine receptor and ketamine?
(2019)Experimental evidence indicates that anesthetic doses of the non-competitive NMDA receptor antagonist ketamine impair memory abilities in rodents. The mechanism by which anesthetic ketamine produces its adverse behavioural ... -
Genicular axial pattern flap for coverage of a hind limb defect caused by dog bites in a ewe
(2021)A ewe was referred with severe dog bite wounds after unsuccessful attendance in a first opinion surgery. A large, complex, contaminated wound was evident in the medial surface of the left tibia. Initial management included ... -
Intra-Abdominal Hypertension Causes Bacterial Growth in Lungs: An Animal Study
(2017)To study the effect of intra-abdominal hypertension (IAH) on the frequency of pneumonia with an experimental study, thirteen Sprague-Dawley rats were included. Eight out of thirteen animals were randomly assigned to receive ... -
Intraoperative initiation of a modified ARDSNet protocol increases survival of septic patients with severe acute respiratory distress syndrome
(2018)Purpose: To assess the intraoperative initiation and feasibility of a modified NIH-NHLBI ARDS Network Mechanical Ventilation Protocol (mARDSNet protocol) in septic patients with severe ARDS. Materials and methods: This ... -
Ketamine disrupted storage but not retrieval of information in male rats and apomorphine counteracted its impairing effect
(2020)Ketamine, a non-competitive NMDA receptor antagonist, has been reported to mimic the cognitive symptoms of schizophrenia in animals. It has been reported to produce learning and memory deficits in rodents. However, there ... -
Liver lobe torsion in a cat with diaphragmatic hernia
(2020)A 10-year-old neutered male domestic shorthair cat was referred with a 2-week history of dyspnoea and anorexia following injury in a car accident. Thoracic radiography and ultrasonography revealed a diaphragmatic hernia. ... -
The nicotinic α7 receptor agonist GTS-21 but not the nicotinic α4β2 receptor agonist ABT-418 attenuate the disrupting effects of anesthetic ketamine on recognition memory in rats
(2020)Several lines of evidence indicate that anesthetic doses of the non-competitive N-methyl-D-aspartate receptor antagonist ketamine disrupt memory functions in rodents. The mechanism by which anesthetic ketamine produces its ... -
