Effects of chronic treatment with testosterone propionate on aggression and hormonal levels in intact male mice.

1998

Effects of testosterone propionate, an anabolic-androgenic steroid (AAS), on aggression in gonadally intact male mice were examined. Animals were given weekly injections of 3.75, 7.5, 15, and 30 mg/kg of drug or sesame oil for 10 weeks. During the last 3 weeks, behavioral tests were conducted and at the end of the experiment, body, liver and testes weight and hormonal data were collected. The treatment had minimal behavioral and endocrine effects. It resulted in shorter latencies of 'threat' only in the last agonistic encounter, increases in testosterone levels and decreases in testes weight in a non-linear dose-dependant way. The action of treatment was different on threat and attack, the …

The role of age and emotional valence in word recognition: an ex-gaussian analysis

2015

[Otro] Cie¿om práce je posúdi¿ vplyv veku a emo¿nej valencie na znovupoznávanie slov v rámci ex-Gaussových distribu¿ných komponentov. Dvom vekovým skupinám sme administrovali test znovupoznávania slov, v ktorom sme manipulovali emo¿nou valenciou. U mladších respondentov sa prejavili štatisticky signifikantné rozdiely pri negatívnych slovách v experimentálnej podmienke a v podmienke s distrakciou. U starších respondentov sme v odpove¿ových ¿asoch nezistili jasnú tendenciu. Vzh¿adom na ex-Gaussovský parameter ¿, ktorý sa v literatúre ¿asto spája s nárokmi na pozornos¿, vekovo podmienené rozdiely v emo¿nej valencii nemali žiaden vplyv na negatívne slová. Ak sa zameriame na emo¿nú valenciu v ob…

On listening to atonal variants of two Piano Sonatas by Beethoven

2009

International audience; We investigated the contribution of tonal relationships to the perception of musical ideas and to the feelings of "arousal." Two excerpts of piano sonatas by Beethoven and two atonal variants were used as experimental stimuli. This manipulation destroyed the tonal relationships but preserved both the local and global temporal organization (rhythm and formal). Listeners were asked to indicate the onset of musical ideas, to estimate the arousing properties of the music in a continuous response task, and to rate the similarity of the pieces. A drastic change in the pitch structure strongly affected judgments of similarity. However, it had no effect on the segmentation o…

Ventilatory conditioning by self-stimulation in rats: A pilot study

1994

International audience; This article describes an experimental attempt to condition breathing pattern in rats. In this experiment, a freely moving rat was first rewarded by an electrical stimulation of the medial forebrain bundle whenever inspiratory duration (TI) exceeded 300 ms. A bidirectional control was then used: TIs longer than 400 ms were rewarded, and then TIs shorter than 300 ms were rewarded. The frequency of TIs longer than 300 ms increased when this event was rewarded, further increased when TIs above 400 ms were rewarded, and decreased during reversal conditioning (TI < 300 ms). At the beginning of the experiment, stimulation caused increased arousal and motor activity, but af…

Alexithymia as a Predictor of Arousal and Affect Dysregulations when Batterers with Attention Deficit Hyperactivity Disorder Cope with Acute Stress

2020

Empirical research has stated that Attention Deficit Hyperactivity Disorder (ADHD) might underlie intimate partner violence against women (IPVAW) perpetration. Even though there is a clear relationship between these two variables, it is still unknown how ADHD facilitates violence proneness. In this regard, psychophysiological variables such as skin conductance levels (SCL) might offer information about emotional regulation when individuals cope with stress. Furthermore, alexithymia traits might be a strong candidate in explaining the above-mentioned emotional dysregulations. Hence, we compared the SCL response to acute cognitive stress in IPVAW perpetrators with and without ADHD symptoms to…

Sexual behaviors and function during menopausal transition—does menopausal hormonal therapy play a role?

2020

Objectives: The menopausal transition is a biological adaptation to the variety of life changes (body, comorbidities, relationship), but that biology is not an “end all” in the context of sexual function and overall sexual health. The aim of this study is to evaluate determinants altering the risk of female sexual dysfunction (FSD) and other sexual problems and to establish whether menopausal hormonal therapy (MHT) decreases that risk and modifies sexual behaviors. Methods: A cross-sectional observational study was conducted in 210 women between the ages of 45 and 55. Two groups were identified: MHT users (n = 107) and controls—MHT non-users (n = 103). Diagnostic and Statistical Manual of M…

Sedation in allergic rhinitis is caused by the condition and not by antihistamine treatment

1996

Sedation is regarded as a common side-effect of most H1-antihistamines. This view must be accepted, yet can hardly be assessed under treatment of allergic disorders. Since central sedative potency is hard to evaluate, different methods of measurement have been introduced in the four phases of clinical investigation. While tests of high complexity in early trials can detect true central effects, they seem to have the disadvantage of not taking into consideration the important interactions of drugs with the disorder. Therefore, we used a visual analog scale (VAS) as an instrument to demonstrate sedative effects in five clinical studies carried out between 1989 and 1994 with a total number of …

Reacción emocional ante la exposición involuntaria a cibersexo en adolescentes: factores moduladores

2019

Los avances realizados durante los últimos años en el ámbito de las tecnologías de la información y comunicación han favorecido un uso generalizado de internet. La población adolescente utiliza Internet de forma natural y habitual para comunicarse, entretenerse y realizar tareas escolares. Si bien son múltiples los beneficios derivados del uso de internet, es necesario considerar que no está exento de riesgos como puede ser la exposición involuntaria (EI) a material sexual. Dadas las consecuencias que dicha exposición puede tener (sobre todo en edades tempranas), nuestro objetivo ha sido analizar las principales reacciones a nivel emocional durante la EI a material sexual, explorando posibl…
