Data from: Controlled feeding experiments with diets of different abrasiveness reveal slow development of mesowear signal in goats (Capra aegagrus hi…
2018
Dental mesowear is applied as a proxy to determine the general diet of mammalian herbivores based on tooth-cusp shape and occlusal relief. Low, blunt cusps are considered typical for grazers and high, sharp cusps typical for browsers. However, how internal or external abrasives impact mesowear, and the time frame the wear signature takes to develop, still need to be explored. Four different pelleted diets of increasing abrasiveness (lucerne, grass, grass and rice husks, grass, rice husks and sand) were fed to four groups of a total of 28 adult goats in a controlled feeding experiment over a six-month period. Tooth morphology was captured by medical CT scans at the beginning and end of the e…
Darba slodzes ietekme uz kognitīvām spējām anestēzijas, intensīvās un neatliekamās terapijas māsām
2019
Latvijā māsu trūkums ir nopietna problēma. Pēc Māsu Asociācijas statistikas datiem, Latvijā no 18 700 māsām strādā tikai 8750 , kas nozīmē, ka visa darba slodze tiek sadalīta starp strādājošo māsu skaitu, kas izraisa pārslodzi māsu vidū. Pēc definīcijas, anestēzijas un intensīvās aprūpes māsām ir jāspēj veikt pacientu aprūpi pirms un pēc operācijas, sekot pacienta stāvoklim, spēt reaģēt akūtās situācijās un sniegt pirmo neatliekamo palīdzību un papildus māsas pamatspecialitātes pienākumi , kuru dēļ var būt pārslodze un kognitīvo spēju samazināšanās, kā arī izveidoties izdegšanas sindroms.
Carboxyl nonsteroidal anti-inflammatory drugs are efficiently glucuronidated by microsomes of the human gastrointestinal tract.
2004
Limited studies have been carried out on the biotransformation of carboxyl nonsteroidal anti-inflammatory drugs (NSAIDs) in the liver. However, the role of the intestine in NSAID metabolism has not been investigated. In this report, the contribution of UDP-glucuronosyltransferases (UGTs) in the human gastrointestinal (GI) tract from five donors to the glucuronidation of the NSAIDs, RS-ketoprofen, S-naproxen, RS- and S-etodolac, was investigated. UGT activity and, for some donors, mRNA levels were evaluated. All NSAIDs were glucuronidated throughout the GI tract; however, glucuronidation was low in stomach and duodenum as compared to the remainder of the intestine. RT-PCR analysis demonstrat…

Zinc acexamate inhibits gastric acid and pepsinogen secretion in the rat.
1990
Abstract Pretreatment with zinc acexamate (25–100 mg kg−1 i.p.) inhibited acid and pepsinogen secretion in the pylorus-ligated rat. Zinc acexamate (5–50 mg kg−1 p.o.) also inhibited the increases in acid secretion induced by carbachol (10 μg kg−1) and 2-deoxy-D-glucose (200 mg kg−1) in the perfused stomach of the anaesthetized rat. A delayed antisecretory effect was observed with this drug on histamine induced responses. High concentrations of zinc acexamate (10−5-10−2 M) did not modify the in-vitro activity of pepsin. Administration of zinc acexamate resulted in an increase in the presence of pepsinogen at the mucosal level. A morphological examination of the gastric mucosa confirmed an ac…
Direct and neuromodulatory effects of histamine on isolated goat cerebral arteries.
1992
1. The effects of histamine on isolated goat middle cerebral artery were examined using two experimental approaches: recording of isometric tension and measurement of [3H]-noradrenaline efflux. 2. Cumulative addition of histamine (10(-7)-3 x 10(-2)M) and 2-pyridylethylamine (2-PEA, 10(-6)-3 x 10(-2)M) produced concentration-dependent contractile responses. Preincubation with diphenhydramine (10(-7), 10(-6)M) or cimetidine (10(-7), 10(-6)M) competitively inhibited the histamine-induced contractile response. 3. Endothelium denudation enhanced the contractile effects of histamine. 4. Transmural electrical stimulation elicited contractions which were enhanced by histamine (10(-7)M), 2-PEA (10(-…
Cost-effectiveness of sofosbuvir-based triple therapy for untreated patients with genotype 1 chronic hepatitis C
2014
We assessed the cost-effectiveness of sofosbuvir (SOF)-based triple therapy (TT) compared with boceprevir (BOC)- and telaprevir (TVR)-based TT in untreated genotype 1 (G1) chronic hepatitis C (CHC) patients discriminated according to IL28B genotype, severity of liver fibrosis, and G1 subtype. The available published literature provided the data source. The target population was made up of untreated Caucasian patients, aged 50 years, with G1CHC and these were evaluated over a lifetime horizon by Markov model. The study was carried out from the perspective of the Italian National Health Service. Outcomes included discounted costs (in euros at 2013 value), life-years gained (LYG), quality-adju…
Motor and Cognitive Performance in Patients with Liver Cirrhosis with Minimal Hepatic Encephalopathy
2020
Minimal hepatic encephalopathy (MHE) is associated with mild cognitive impairment and frailty. This study aims to identify cognitive and motor differences in cirrhotic patients with and without MHE, and the correlations between motor signs and cognitive performance. Gait, balance, hand strength and motor speed performance were evaluated in 66 cirrhotic patients (38 without and 28 with MHE, according to the Psychometric Hepatic Encephalopathy Score (PHES). Cognitive performance was measured with the Mini-Mental State Examination, Verbal Fluency Test, Aprendizaje Verbal España-Complutense Test (TAVEC), Wechsler Adult Intelligence Scale III, Hamilton Depression and Anxiety Rating Scale and Fun…
Clinical management of drug-drug interactions in HCV therapy: Challenges and solutions.
2013
Contains fulltext : 118153.pdf (Publisher’s version ) (Open Access) Hepatitis C virus (HCV) infected patients often take multiple co-medications to treat adverse events related to HCV therapy, or to manage other co-morbidities. Drug-drug interactions associated with this polypharmacy are relatively new to the field of HCV pharmacotherapy. With the advent of the direct-acting antivirals telaprevir and boceprevir, which are both substrates and inhibitors of the cytochrome P450 (CYP) 3A iso-enzyme, knowledge and awareness of drug-drug interactions have become a cornerstone in the evaluation of patients starting and continuing HCV combination therapy. In our opinion, an overview of conducted dr…
Direct-acting antivirals ombitasvir/paritaprevir/rotonavir+dasabuvir with or without ribavirin in hepatitis C virus (HCV) genotype 1-infected treatme…
2018
Background: The current international multicentre open-label, uncontrolled, real-world retrospective study aimed at evaluating the effectiveness and safety of ombitasvir / paritaprevir / ritonavir + dasabuvir ± ribavirin (3D therapy) in treatment-naive and treatment-experienced hepatitis C virus (HCV) genotype 1-infected (GT1) patients. Methods: Adult patients with chronic HCV GT1 infection, scheduled for 3D therapy according to therapeutic guidelines, were eligible. Demographic and clinical data were collected retrospectively by reviewing individuals health records. The primary effectiveness endpoint was the sustained virological response at 12 weeks following the end of treatment (SVR12).…
