Muscarine receptors on the rat phrenic nerve, evidence for positive and negative muscarinic feedback mechanisms.
1987
Neuronal transmitter stores of the rat phrenic nerve were labelled by incubation with [3H]choline. Release of [3H]acetylcholine was elicited by electrical nerve stimulation (100 or 1500 pulses, 5 or 25 Hz) or by high potassium (27 mmol/l) and the effects of the muscarine receptor agonist oxotremorine and the antagonist scopolamine were investigated. Neither oxotremorine nor scopolamine affected the basal tritium efflux. A low concentration of oxotremorine (10 nmol/l) enhanced and a high concentration of oxotremorine (1 μol/l) reduced the electrically evoked [3H]acetylcholine release. Likewise, the high potassium-evoked [3H]acetylcholine release was reduced by a high concentration of oxotrem…
The induction of hepatic microsomal metabolism in rats following acute administration of a mixture of polybrominated biphenyls.
1976
Abstract Firemaster BP6, a mixture of polybrominated biphenyls (PBBs), was administered to female Sprague-Dawley rats (170–180 g) as a single ip injection at 25 and 150 mg/kg. Other animals received phenobarbital (PB), 3-methylcholanthrene (3MC), or PB and 3MC together. Animals were killed at intervals of 12, 24, 48, 192, and 336 hr after treatment with PBBs, or 24 hr after PB, MC, or PB-MC, and various hepatic microsomal parameters were measured. After 150 mg/kg of PBBs, cytochrome P450 concentrations reached a maximum by 48 hr (225% of control), then remained elevated through 336 hr. A similar pattern of induction was observed for epoxide hydratase and aniline hydroxylase activities. In c…
Dropped head as an unusual presenting sign of myasthenia gravis.
2007
Prominent or isolated weakness of cervical extensor muscles is a relatively rare clinical sign. Commonly, this is known as "dropped-head syndrome". This abnormal flexion of the head may occur in a variety of neuromuscular diseases and in a few non-neurological disorders as well. The case we describe concerns a 61-year-old woman with dropped-head syndrome as the unique complaint of myasthenia gravis.
Medical treatment for inoperable malignant bowel obstruction: a qualitative systematic review.
2007
The use of symptomatic agents has greatly improved the medical treatment of advanced cancer patients with inoperable bowel obstruction. A systematic review of studies of the most popular drugs used in the medical management of inoperable malignant bowel obstruction was performed to assess the effectiveness of these treatments and provide some lines of evidence. Randomized trials that involved patients with a clinical diagnosis of intestinal obstruction due to advanced cancer treated with these drugs were reviewed. Five reports fulfilled inclusion criteria. Three studies compared octreotide (OC) and hyoscine butylbromide (HB), and two studies compared corticosteroids (CSs) and placebo. Globa…

Evaluación del efecto de duloxetina y pregabalina en un modelo de fibromialgia inducida por reserpina en rata
2017
INTRODUCCIÓN El síndrome de fibromialgia (FMS) es una enfermedad que se caracteriza principalmente por dolor muscular crónico generalizado o multifocal de origen desconocido, y la co-existencia de otras manifestaciones clínicas, como las alteraciones del estado de ánimo, los trastornos del sueño, la fatiga, la rigidez matutina, las disfunciones cognitivas, la ansiedad, los dolores de cabeza recurrentes, los mareos, el síndrome de colon irritable y/o el dolor urogenital. La alta prevalencia de este síndrome en la población general plantea un problema social y económico, además, la complejidad de su diagnóstico y la falta de eficacia y efectividad de los tratamientos farmacológicos evidencia …
Visualization of Moiré Magnons in Monolayer Ferromagnet
2023
| openaire: EC/H2020/788185/EU//E-DESIGN Two-dimensional magnetic materials provide an ideal platform to explore collective many-body excitations associated with spin fluctuations. In particular, it should be feasible to explore, manipulate, and ultimately design magnonic excitations in two-dimensional van der Waals magnets in a controllable way. Here we demonstrate the emergence of moiré magnon excitations, stemming from the interplay of spin-excitations in monolayer CrBr3 and the moiré pattern arising from the lattice mismatch with the underlying substrate. The existence of moiré magnons is further confirmed via inelastic quasiparticle interference, showing the appearance of a dispersion …

Introducción: La fibromialgia (FM) es un síndrome complejo que se caracteriza por dolor crónico difuso y generalizado en el sistema musculoesquelético, acompañado de otros síntomas, tales como fatiga, alteraciones del sueño, parestesias y rigidez articular. Estos síntomas provocan una disminución de la capacidad funcional y, en consecuencia, de la calidad de vida de la persona afectada. En este síndrome también se ven alteradas la dimensión emocional en aspectos como la ansiedad, depresión y estrés. La manifestación clínica más común que presentan las personas que sufren FM es el dolor, con una disminución de su umbral, acompañado de hiperalgesia y alodinia. Estas características se han rel…
Modulation of type II collagen-induced arthritis in DBA/1 mice by intravenous application of a peptide from the C1q-A chain.
1992
In this report we are able to show that intravenous (i.v.) application (day 0) of a nonapeptide (residues 26-34) from the human C1q A-chain (designated peptide A-C1q) prior to intradermal (i.d.) administration of chicken type II collagen (CII) in arthritis-susceptible DBA/1 mice (H2q), leads to abrogation of polymorphonuclear neutrophil (PMN) invasion into the joints. This nonapeptide exhibits epitope characteristics and high homology to residues 137-147 of CB11 (a cyanogen bromide fragment of chicken CII, known to contain both arthritis inducing and suppressing determinants). Arthritis index was lowest in animals pretreated i.v. with CII (as internal control), though animals pretreated i.v…
