Pulse wave analysis by digital photoplethysmography to record maternal hemodynamic effects of spinal anesthesia, delivery of the baby, and intravenous oxytocin during cesarean section

Objective: To investigate changes in maternal ECG ST index, blood pressure (BP), cardiac left ventricular (LV) ejection function and vascular tone/stiffness in large and small arteries occurring during elective cesarean section (CS) in spinal anesthesia. Material and methods: Twenty-six women were monitored with photoplethysmographic digital pulse wave (PW) analysis (DPA) before and after spinal a

A synthesis of studies on renovation profitability

Still, the building sector in Sweden repeatedly fails in using experiences from both fulfilled projects through feedback and existing research information. The use of earlier results would be beneficial for the process of developing appropriate and competing product and services, and would help avoiding crucial mistakes that risk the functionality of constructed buildings. It is also important to

The costs of friendship : severe mental illness, poverty and social isolation

Background: The relationship between severe mental illness, poverty and social isolation has been explored in a number of studies. Aim: The purpose of the study was to explore the relationship between financial strain and social isolation. Methods: Sixteen persons with severe mental illness were interviewed about their experience of having a severe mental illness, living in poverty and the effect

Corticosteroids or Not for Postoperative Nausea : A Double-Blinded Randomized Study

Background: Postoperative nausea and vomiting (PONV) is common after general anaesthesia, and corticosteroids are used in many protocols for enhanced recovery after surgery (ERAS). However, surgical techniques are developing, and ERAS protocols need to be reevaluated from time to time. Patients and method: In this study, we compared the effects of oral vs. parenteral corticosteroid administration

Fixation stability and implication for multifocal electroretinography in patients with neovascular age-related macular degeneration after anti-VEGF treatment

Purpose: To quantify fixation stability in patients with neovascular age-related macular degeneration (nAMD) at baseline, 3 and 6 months after anti-vascular endothelial growth factor (anti-VEGF) treatment and furthermore asses the implications of an unsteady fixation for multifocal electroretinography (mfERG) measurements. Methods: Fifty eyes of 50 nAMD patients receiving intravitreal anti-VEGF tr

Palaeolithic diet decreases fasting plasma leptin concentrations more than a diabetes diet in patients with type 2 diabetes : A randomised cross-over trial

Background: We have previously shown that a Palaeolithic diet consisting of the typical food groups that our ancestors ate during the Palaeolithic era, improves cardiovascular disease risk factors and glucose control compared to the currently recommended diabetes diet in patients with type 2 diabetes. To elucidate the mechanisms behind these effects, we evaluated fasting plasma concentrations of g

Salbutamol for transient tachypnea of the newborn

Background: Transient tachypnea of the newborn is characterized by tachypnea and signs of respiratory distress. Transient tachypnea typically appears within the first two hours of life in term and late preterm newborns. Although transient tachypnea of the newborn is usually a self limited condition, it is associated with wheezing syndromes in late childhood. The rationale for the use of salbutamol

Biological effects of aminoguanidine : an update

Aminoguanidine (AMG) was prepared more than 100 years ago. During the last 10 years two important effects of AMG have been discovered which have made this molecule attract a lot of interest. Firstly, AMG inhibits, in vitro and in vivo, formation of highly reactive advanced glycosylation end products (AGEs) associated with pathogenesis of secondary complications to diabetes and with cardiovascular

Immunocytochemical demonstration of oestrogen receptor beta in blood vessels of the female rat

The role of oestrogen receptor (ER) beta in vascular function remains unclear. With the use of a specific ERbeta antibody we have now, using immunocytochemistry, visualized ERbeta in different parts of the vascular tree. In about 70% of medial smooth muscle cells of female rat aorta, tail artery and uterine artery, nuclear immunoreactivity to ERbeta was observed. In these vessels endothelial cells

Inhibition of serum diamine oxidase discloses a constitutive putrescine release from cultured vascular smooth muscle cells

OBJECTIVE: To determine if putrescine and the higher polyamines spermidine and spermine are released from cultured vascular smooth muscle cells.MATERIAL: Vascular smooth muscle cell line A7r5.TREATMENT: Cells were treated with aminoguanidine (10 or 100 microM) for 1 to 24 h with or without fetal calf serum (10%) present in the culture medium.METHODS: Cellular and medium concentrations of polyamine

Inhibition of diamine oxidase promotes uptake of putrescine from rat small intestine

In blood from the portal vein of anaesthetized rats the levels of histamine and putrescine were 2-3-fold lower compared to arterial blood. Putrescine concentration was increased severalfold and the difference between portal and arterial blood abolished in animals pretreated with the specific diamine oxidase inhibitor aminoguanidine. Histamine concentration was 40% lower in portal compared to arter

Differential actions of exogenous and intracellular spermine on contractile activity in smooth muscle of rat portal vein

Effects of the naturally occurring polyamine spermine on electrical and contractile properties of the rat portal vein were studied. 1 mM spermine nearly abolished spike activity and spontaneous contractions and decreased the intracellular Ca2+ concentration ([Ca2+]i). The phasic force responses to 0.1 and 1 microM phenylephrine were partially inhibited, but not the sustain plateau contraction caus

Epinephrine for transient tachypnea of the newborn

Background: Transient tachypnea of the newborn is characterized by tachypnea and signs of respiratory distress. Transient tachypnea typically appears within the first two hours of life in term and late preterm newborns. Although transient tachypnea of the newborn is usually a self limited condition, it is associated with wheezing syndromes in late childhood. The rationale for the use of epinephrin

Effects of luminal stimuli on polyamine metabolism in the small intestine of the rat : the role of enteric nerves

The aim of this study was to investigate to what extent polyamine metabolism in the small intestine of the rat is controlled by the enteric nervous system. Polyamine metabolism was followed by measuring the activity of ornithine decarboxylase (ODC) and in some instances also the content of polyamines (putrescine, spermidine and spermine). ODC activity in the intestine was increased when intralumin

Effects of receptor agonists on polyamine concentrations and spermidine/spermine N1-acetyltransferase activity in rat parotid gland

The polyamine putrescine might be formed via a degradation (catalyzed by spermidine/spermine N1-acetyltransferase, SSAT) of the higher polyamines spermidine and spermine to putrescine. The involvement of different intracellular signal pathways in the regulation of putrescine formation was studied in explants and in cultured cells of rat parotid glands by using receptor agonists that activate separ

Release of polyamines in cultures of rat parotid and liver cells

Rat parotid gland and liver cells were cultured for 6 and 24 h. The cells as well as their growth medium were analyzed on their content of the polyamines putrescine, spermidine and spermine. In control medium the content of polyamines was very low but already after 6 h substantial amounts of all three polyamines under study had been released into the medium from parotid as well as from liver cells

Effects of stimulation of the parasympathetic and sympathetic innervations in bursts on the syntheses of polyamines, DNA and protein in salivary glands of the rat;non-adrenergic, non-cholinergic responses : non-adrenergic, non-cholinergic responses

The increase in the activity of ornithine decarboxylase, the key enzyme in the formation of polyamines, in the sublingual glands of the chloralose-anaesthetized rat in response to stimulation of the parasympathetic innervation was enhanced by employing an intermittent pattern of nerve stimulation. 20 Hz in bursts delivered for 1 second every 10th second over a period of 3 hours increased the activ

Polyamines and long-term disuse of rat parotid glands

A decrease in nerve reflex activation for 7-14 days, induced by a liquid diet, caused the rat parotid gland to lose weight, involving reduction in both cell size and number. In the atrophied glands, the activity of ornithine decarboxylase, the key enzyme in polyamine formation, and the levels of the polyamines putrescine, spermidine and spermine were found to be lowered. The present results are co
