Serotonin control of central dopaminergic function: focus on in vivo microdialysis studies

2008

In this review, the functional interactions between serotonin (5-HT) and dopamine (DA) neuronal systems are discussed with the focus on microdialysis studies in the rodent brain (mainly rats). 5-HT by itself is involved both directly and indirectly via actions on complex neuronal circuitry, in the regulation of DA release through multiple 5-HT receptors, playing a critical role in the development of normal and abnormal behaviours. Recent evidence suggests that dysfunction of dopaminergic and serotoninergic neurotransmitter systems contributes to various disorders including depression, schizophrenia, Parkinson's disease and drug abuse. Here we summarize recent neurochemical works that have e…

ABATEMENT OF ACID ORANGE 7 IN WATER BY DIFFERENT ELECTROCHEMICAL APPROACHES

2014

Very large amounts of synthetic dyes are discharged in the environment from industrial effluents [1]. Due to their large-scale production and extensive application, synthetic dyes can cause considerable nonaesthetic pollution and are serious health-risk factors [2]. Dyes are commonly classified from their chromophore group. The majority of these compounds consumed at industrial scale are azo (–N=N–) derivatives that represent more than 50% of the all dyes used in textile industries, although antraquinone, indigoide, triphenylmethyl, xanthene, sulphur and phtalocyanine derivatives are frequently utilized [3]. Since dyes usually present high stability under sunlight and resistance to microbia…

Application of computational fluid dynamics technique in electrodialysis/reverse electrodialysis processes

2022

This Chapter treats the application of CFD technique in ED/RED processes. CFD simulations are able to predict flow and mass transfer in channels filled with spacers or membrane profiles, by providing dimensionless correlations useful for process models. At a larger scale, manifolds of the stack and inlet/ outlet zones of the channel can be simulated. Numerical models can include the computation of the electrical potential, thus characterizing the process performance. Direct numerical simulations can elucidate the complex phenomenology of overlimiting transport and of chaotic electrokinetic flows.

Traditional and new types of spondarthritis with special consideration of spondylodiscitis

1990

In rheumatology the so-called "seronegative spondarthritis" is a group of diseases characterized by the presence of HLA-B 27. This group includes the typical ankylosing spondylitis as well as atypical spondylopathies such as those occurring in psoriasis, Reiter's disease and chronic inflammatory enteropathies, which attack mainly the spine and secondarily the peripheral joints. In some severe cases, non-infectious, sterile spondylodiscitis was observed. These can lead to instability and fracture, followed by pseudarthrosis of the involved segment of the spine. In contrast to these traditional spondarthritides three new types are marked by the lack of HLA-B 27. 1) "Spondarthritis hyperostoti…

Multiple osteoartikuläre Komplikationen (dialyse-assoziierte Spondarthropathie) und Karpaltunnelsyndrom bei chronischer Hämodialyse

2008

Abstract During a nine-year treatment by haemodialysis for renal failure a now 57-year-old woman developed multiple complications of the skeletal system. Acute calcific periarthritis of the right shoulder became manifest one year after the start of the haemodialysis, followed the next years by progressive arthropathy with subchondral amyloid cysts of both shoulders, effusions in the knee-joint and destructive spondylarthropathy of the middle vertebrae. Carpal-tunnel syndrome also occurred, caused by a beta 2-microglobulin amyloidosis (beta 2-microglobulin concentration in serum 42.6 ng/l) and an aluminium osteopathy. These multiple complications, observed here in one patient, are each of th…

Impact of Obesity in Kidney Diseases.

2021

The clinical consequences of obesity on the kidneys, with or without metabolic abnormalities, involve both renal function and structures. The mechanisms linking obesity and renal damage are well understood, including several effector mechanisms with interconnected pathways. Higher prevalence of urinary albumin excretion, sub-nephrotic syndrome, nephrolithiasis, increased risk of developing CKD, and progression to ESKD have been identified as being associated with obesity and having a relevant clinical impact. Moreover, renal replacement therapy and kidney transplantation are also influenced by obesity. Losing weight is key in limiting the impact that obesity produces on the kidneys by reduc…

Relationship of oxidant stress with endothelial activation in hemodialysed hypertensive patients.

Could emotional processing influence pain perception and quality of life in chronic kidney disease and hemodialyzed patients?

2017

Background and Objectives: The incidence of chronic pain is 11-24% in general population, whereas it affects 50% of hemodialyzed subjects and is often secondary to comorbidities, CKD-related complications and certain clinical procedures. Consequently, a better approach in evaluating pain as a “symptom” and in managing it adequately is required for these patients. Methods: 33% of the 300 patients enrolled properly consigned the questionnaires. The mean age of dialyzed patients was 52.2±11.2 years, whereas 54.9±10.7 years was the mean age for CKD patients. Moreover, 53 healthy subjects, ages 20-65, have been included in the study as control group. Specific psycho-diagnostic tests were adminis…

Feasible Low-Phosphorus Dietary Patterns in Maintenance Hemodialysis Patients: Need for Original Research

2020

Introduction The standard low-phosphorus diet restricts pulses, nuts, and whole grains and other high phosphorus foods to control hyperphosphatemia. We conducted a randomized controlled trial to evaluate the effectiveness, safety, and tolerability of the modified diet, which introduced some pulses and nuts, increased the use of whole grains, increased focus on the avoidance of phosphate additives, and introduced the prescription of low-biological-value protein such as bread. Methods We conducted a multicenter, pragmatic, parallel-arm, open-label, randomized controlled trial of modified versus standard diet in 74 adults on hemodialysis with hyperphosphatemia over 1 month. Biochemistry was as…
