Barriers to promote cardiovascular health in community pharmacies: a systematic review.

Community pharmacists play an important role in the provision of health promotion services, and community pharmacies are considered as a potentially ideal site for cardiovascular health promotion. Information based on a systematic review of barriers to promoting cardiovascular health in community pharmacy is currently lacking. We have sought to identify the most important barriers to cardiovascular health promotion in the community pharmacy.

[Evaluation of a nutritional intervention among elderly people: the Edumay project].

Background: The adherence to a Mediterranean Dietary Pattern is associated with a morbi-mortality reduction, and with a better quality of life.

Objectives: To evaluate a nutritional intervention among independent elderly people enrolled in an educational program to increase the knowledge of the food and daily diets, promoting a healthy dietary pattern.

Methods: Quasi-experimental design conducted in elderly participants who lived in foster home apartments owned by the City Council of Pamplona (n = 41).

Neonatal stress affects vulnerability of cholinergic neurons and cognition in the rat: involvement of the HPA axis.

Adverse experiences early in life may sensitize specific neurocircuits to subsequent stressors. We have evaluated in maternal separation (MS) rats, an animal paradigm of early-life stress, the effects of a selective cholinergic lesion on cognitive function as well as susceptibility of cholinergic neurons to the lesion. MS rats subjected to a cholinergic lesion by administration of the immunotoxin 192 IgG-saporin, showed significant decreases in both choline acetyltransferase (ChAT) and acetylcholinesterase (AChE) activity compared to control lesioned rats.

Effects of neonatal stress on markers of synaptic plasticity in the hippocampus: implications for spatial memory.

Early stressful adverse situations may increase the vulnerability to cognitive deficits and psychiatric disorders, such as depression. Maternal separation (MS) has been used as an animal model to study changes in neurochemistry and behavior associated with exposure to early-life stress. This study investigated the effects of neonatal stress (MS) on the expression of synaptic plasticity markers in the hippocampus and a purported relationship to cognitive processes.

Phosphodiesterase 5 inhibitors prevent 3,4-methylenedioxymethamphetamine-induced 5-HT deficits in the rat.

Phosphodiesterase 5 (PDE5) inhibitors are often used in combination with club drugs such as 3,4-methylenedioxymethamphetamine (MDMA or ecstasy). We investigated the consequences of such combination in the serotonergic system of the rat. Oral administration of sildenafil citrate (1.

On the role of tyrosine and peripheral metabolism in 3,4-methylenedioxymethamphetamine-induced serotonin neurotoxicity in rats.

The mechanisms underlying 3,4-methylenedioxymethamphetamine (MDMA)-induced serotonergic (5-HT) toxicity remain unclear. It has been suggested that MDMA depletes 5-HT by increasing brain tyrosine levels, which via non-enzymatic hydroxylation leads to DA-derived free radical formation. Because this hypothesis assumes the pre-existence of hydroxyl radicals, we hypothesized that MDMA metabolism into pro-oxidant compounds is the limiting step in this process.

The relationship between core body temperature and 3,4-methylenedioxymethamphetamine metabolism in rats: implications for neurotoxicity.

Rationale: A close relationship appears to exist between 3,4-methylenedioxymethamphetamine (MDMA)-induced changes in core body temperature and long-term serotonin (5-HT) loss.

Objective: We investigated whether changes in core body temperature affect MDMA metabolism.

Materials And Methods: Male Wistar rats were treated with MDMA at ambient temperatures of 15, 21.

Minoxidil prevents 3,4-methylenedioxymethamphetamine-induced serotonin depletions: role of mitochondrial ATP-sensitive potassium channels, Akt and ERK.

Preconditioning has emerged as a valid strategy against different neurotoxic insults. Although the mechanisms underlying preconditioning are not fully understood, the activation of ATP-sensitive potassium (KATP) channels has been proposed to play a pivotal role in neuronal preconditioning. In the present work we examine whether minoxidil a KATP channel activator protects against the long-term toxicity caused by the amphetamine derivative 3,4-methylenedioxymethamphetamine (MDMA) in rats.

Factors that influence under-reporting of suspected adverse drug reactions among community pharmacists in a Spanish region.

Background: The spontaneous reporting system is the most efficient warning system of adverse drug reactions (ADRs). Pharmacists can play an important role in the detection and reporting of ADRs. The factors that affect under-reporting among these professionals are unknown in Spain.

Studies on the mechanisms underlying amiloride enhancement of 3,4-methylenedioxymethamphetamine-induced serotonin depletion in rats.

Amiloride and several of its congeners known to block the Na(+)/Ca(2+) and/or Na(+)/H(+) antiporters potentiate methamphetamine-induced neurotoxicity without altering methamphetamine-induced hyperthermia. We now examine whether amiloride also exacerbates 3,4-methylenedioxymethamphetamine (MDMA)-induced long-term serotonin (5-HT) loss in rats. Amiloride (2.

Cognitive impairment associated to HPA axis hyperactivity after maternal separation in rats.

Exposure to early stressful adverse life events may increase vulnerability to psychopathology in adult life. There are important memory disturbances in stress-related psychiatric disorders. Therefore, there is much interest in understanding the mechanisms responsible for interactions between stress and cognition.

Effect of selective cholinergic denervation on the serotonergic system: implications for learning and memory.

The cholinergic system has been widely implicated in cognitive processes and cholinergic loss is a classical hallmark in Alzheimer disease. Increasing evidence supports a role of the serotonergic system in cognition, possibly through a modulation of cholinergic activity. We compared selective cholinergic denervation by administration of the immunotoxin 192 IgG-saporin in the nucleus basalis of Meynert (NBM) with intracerebroventricular (ICV) lesions of the basal forebrain in male rats 7 days after lesioning.

Studies on striatal neurotoxicity caused by the 3,4-methylenedioxymethamphetamine/ malonate combination: implications for serotonin/dopamine interactions.

The amphetamine derivative 3,4-methylenedioxymethamphetamine (MDMA) produces long-term toxicity to serotonin (5-HT) neurones in rats, which is exacerbated when combined with the mitochondrial inhibitor malonate. Moreover, MDMA, which does not produce dopamine depletion in the rat, potentiates malonate-induced striatal dopamine toxicity. Because the malonate/MDMA combination acutely causes a synergistic increase of 5-HT and dopamine release, in this study we sought to determine whether pharmacological blockade of MDMA- and/or malonate-induced dopamine release prevents neurotoxicity.

Facilitation of cholinergic transmission by combined treatment of ondansetron with flumazenil after cortical cholinergic deafferentation.

We have studied the effects of concomitant blockade of 5-HT(3) and GABA(A) receptors on acetylcholine (ACh) release in the frontal cortex of rats with a selective cholinergic lesion. Lesions were performed by microinjection of the cholinergic toxin 192 IgG-saporin into the nucleus basalis magnocellularis. Single treatment with either the 5-HT(3) receptor antagonist ondansetron, 0.

GABA(A) receptor antagonists enhance cortical acetylcholine release induced by 5-HT(3) receptor blockade in freely moving rats.

ACh release from the rat frontal cortex was increased by both local, 0.1-1 microM, and systemic, 0.1-10 microg/kg, administration of the 5-HT(3) receptor antagonist ondansetron, reaching a maximum peak of 143% over basal values.

Synthesis and molecular modeling of new 1-aryl-3-[4-arylpiperazin-1-yl]-1-propane derivatives with high affinity at the serotonin transporter and at 5-HT(1A) receptors.

It has been proposed that 5-HT(1A) receptor antagonists augment the antidepressant efficacy of selective serotonin (5-HT) reuptake inhibitors. In a search toward new and efficient antidepressants, 1-(aryl)-3-[4-arylpiperazin-1-yl]-1-propane molecular hybrids were designed, synthesized, and evaluated for 5-HT reuptake inhibition and 5-HT(1A) receptor affinity. The design was based in coupling structural moieties related to inhibition of serotonin reuptake, such as benzo[b]thiophene derivatives to arylpiperazines, typical 5-HT(1A) receptor ligands.

Antidepressant-like activity of VN2222, a serotonin reuptake inhibitor with high affinity at 5-HT1A receptors.

It has been suggested that drugs combining serotonin (5-hydroxytryptamine, 5-HT) transporter blockade and 5-HT1A autoreceptor antagonism could be a novel strategy for a shorter onset of action and higher therapeutic efficacy of antidepressants. The present study was aimed at characterizing the pharmacology of 1-(3-benzo[b]tiophenyl)-3-[4-(2-methoxyphenyl)-1-piperazinyl]-1-propanol (VN2222) a new synthetic compound with high affinity at both the 5-HT transporter and 5-HT1A receptors and devoid of high affinity at other receptors studied, with the only exception of alpha1-adrenoceptors. In keeping with the binding affinity at the 5-HT transporter, VN2222 inhibited 5-HT uptake in vitro both in rat cortical synaptosomes and in mesencephalic cultures and also in vivo when administered locally into the rat ventral hippocampus.
