Introduction This study aims to describe the characteristics and circumstances related to caregiving at home of family caregivers of people receiving palliative care at home due to cancer disease. Method Design: Descriptive, cross-sectional study. Sample: family caregivers of people in follow-up in the home care program. Period: July/2015 to December/2016. Variables: sociodemographic data, characteristics of the role of caregiver as previous experience caring, reasons for caring, living together, simultaneous care of other people, care environment preferences, perception of the relationship, time and hours assuming care. Results The sample was made up of a total of 80 relatives, 56 (70%) we…

Effects of nicotine receptor agonists on acetylcholine release from the isolated motor nerve, small intestine and trachea of rats and guinea-pigs

1992

The effects of nicotine receptor agonists on the release of [3H]acetylcholine from the phrenic nerve, the small intestine and the trachea were investigated to characterize neuronal nicotine receptors within the peripheral nervous system. Contraction of the indirectly-stimulated hemidiaphragm was recorded to investigate desensitization of the postsynaptic muscular nicotine receptors. Nicotine, cytisine, 1,1-dimethyl-4-phenylpiperazinium and 2-(4-aminophenyl)-ethyl-trimethyl-ammoniumiodide caused a concentration-dependent (0.1-30 microM) increase in evoked [3H]acetylcholine release from the phrenic nerve, whereby bell-shaped concentration-response curves were obtained. The rank order of decre…

Dualistisches Fortpflanzungsverhalten bei dem protogynen LippfischThalassoma bifasciatum und einige Beobachtungen über dessen Tag-Nacht-Wechsel

1973

1.Thalassoma bifasciatum is a protogynous wrasse with (partial) sexual dimorphism and male dichromatism. Sex-inversion takes place without affecting the color pattern. 2. Males with female-like color dress indulge in group spawning; males with the bright color pattern perform pair spawning. 3. Among the brightly colored males exists a well-established hierarchy. Dominant males only have a particular spawning area in which they spawn daily at a certain time around noon. The spawning area is optically marked by conspicuous behavior of the bright male. Courtship activities towards individual partners are rather superficial. 4. The female has the leading role in pair spawning. In the extremely …

D1 receptors play a major role in the dopamine modulation of mouse ileum contractility

2010

Since the role of dopamine in the bowel motility is far from being clear, our aim was to analyse pharmacologically the effects of dopamine on mouse ileum contractility. Contractile activity of mouse ileum was examined in vitro as changes in isometric tension. Dopamine caused a concentration-dependent reduction of the spontaneous contraction amplitude of ileal muscle up to their complete disappearance. SCH-23390, D1 receptor antagonist, which per se increased basal tone and amplitude of spontaneous contractions, antagonized the responses to dopamine, whilst sulpiride or domperidone, D2 receptor antagonists, were without effects. The application of both D1 and D2 antagonists had additive effe…

Cocaine and MDMA Induce Cellular and Molecular Changes in Adult Neurogenic Systems: Functional Implications

2011

The capacity of the brain to generate new adult neurons is a recent discovery that challenges the old theory of an immutable adult brain. A new and fascinating field of research now focuses on this regenerative process. The two brain systems that constantly produce new adult neurons, known as the adult neurogenic systems, are the dentate gyrus (DG) of the hippocampus and the lateral ventricules/olfactory bulb system. Both systems are involved in memory and learning processes. Different drugs of abuse, such as cocaine and MDMA, have been shown to produce cellular and molecular changes that affect adult neurogenesis. This review summarizes the effects that these drugs have on the adult neurog…

Effect of β-cryptoxanthin plus phytosterols on cardiovascular risk and bone turnover markers in post-menopausal women: a randomized crossover trial.

2014

Abstract Background and aim Post-menopausal women are at higher risk of cardiovascular disease and bone demineralization. Phytosterols (PS) may be used for hypercholesterolemia in some groups and β-cryptoxanthin (β-Cx) displays a unique anabolic effect on bone. Our aim was to assess the changes in cardiovascular and bone turnover markers from the oral intake of β-Cx and PS in post-menopausal women. Methods and results A randomized, double-blind, crossover study with β-Cx (0.75 mg/day) and PS (1.5 g/day), single and combined, was performed in 38 postmenopausal women. Diet was supplemented with 1 × 250 mL milk-based fruit drink/day for 4 weeks with a wash-out period of 4-weeks in between. Ser…

The assessment of vertebral fractures in elderly women with recent hip fractures: the BREAK Study

2012

This study aimed to evaluate the prevalence of vertebral fractures in elderly women with a recent hip fracture. The burden of vertebral fractures expressed by the Spinal Deformity Index (SDI) is more strictly associated with the trochanteric than the cervical localization of hip fracture and may influence short-term functional outcomes. INTRODUCTION: This study aimed to determine the prevalence and severity of vertebral fractures in elderly women with recent hip fracture and to assess whether the burden of vertebral fractures may be differently associated with trochanteric hip fractures with respect to cervical hip fractures. METHODS: We studied 689 Italian women aged 60 years or over with …

Oxytocin reduces romantic rejection-induced pain in online speed-dating as revealed by decreased frontal-midline theta oscillations

2021

Abstract Background Romantic rejection is an emotionally distressful experience profoundly affecting life, possibly leading to mental illness or suicide. Oxytocin (OT) is a neuropeptide widely implicated in reducing physical pain and negative emotions; however, whether OT has an effect on reducing intense social pain (e.g., romantic rejection) remains unknown. Here, we tested the effect of OT on social pain and investigated its role in the outcome evaluation phase of social decision-making. Methods Electroencephalographic recordings were obtained between August 2nd and October 20th, 2020 in Shenzhen University from 61 healthy participants in a double-blind, placebo-controlled study with a b…

Similar efficacy of low and standard doses of transdermal estradiol in controlling bone turnover in postmenopausal women

2006

To investigate the effects of a low transdermal estradiol dose on bone metabolism and to compare it with both the standard dose and absence of treatment.In this study performed in a third-level academic center, 66 healthy postmenopausal women underwent hormone therapy (HT) with patches containing estradiol at standard (0.050 mg/day, HT50, 33 women) or low dosage (0.025 mg/day, HT25, 33 women) and 70 women were without treatment (NT). The values (mean of three samples) of several bone biochemical parameters were compared between groups after adjusting for confounding factors. Bone mineral density (BMD) was assessed (by dual-energy X-ray absorptiometry) in the spine and hip in all cases, and …
