Perimenopausal women show modulation of excitatory and inhibitory neuromuscular mechanisms.

2021

Background Menopausal transition exposes women to an early decline in muscle force and motor function. Changes in muscle quality and function, especially in lower limbs, are crucial, as they expose individuals to increased risk of falls. To elucidate some of the related neuromuscular mechanisms, we investigated cortical inhibition and peripheral muscle twitch force potentiation in women during the early and late stages of perimenopause. Methods Participants were 63 women aged 48–55 years categorized as early (EP, n = 25) or late (LP, n = 38) perimenopausal according to serum follicle-stimulating hormone (FSH) levels and menstrual diaries. EP women had an irregular menstrual cycle and FSH  2…

Short-term responses of Rana arvalis tadpoles to pH and predator stress: adaptive divergence in behavioural and physiological plasticity?

2022

Environmental stress is a major driver of ecological and evolutionary processes in nature. To cope with stress, organisms can adjust through phenotypic plasticity and/or adapt through genetic change. Here, we compared short-term behavioural (activity) and physiological (corticosterone levels, CORT) responses of Rana arvalis tadpoles from two divergent populations (acid origin, AOP, versus neutral origin, NOP) to acid and predator stress. Tadpoles were initially reared in benign conditions at pH 7 and then exposed to a combination of two pH (acid versus neutral) and two predator cue (predator cue versus no predator cue) treatments. We assessed behavioural activity within the first 15 min, an…

Efectos de la i-logica capitalista en la violencia de genero

2015

Las autoras de este artículo reflexionan sobre los cierres y recortes en recursos de servicios sociales en general y de atención a las mujeres víctimas de violencia de género en particular, concluyendo que es la ideología mercantilista aplicada a los recursos sociales de atención a los más necesitados, la principal causante de que estos no funcionen adecuadamente y de que las mujeres víctimas de violencia en muchos casos no reciban la atención que seria necesaria.

Replication of herpes simplex virus type 1 and 2 in the medulla of the adrenal gland after vaginal infection of mice.

1996

After vaginal infections of mice with neuroinvasive strains of herpes simplex virus type 1 and 2 (HSV-1, HSV-2) virus replicates in the epithelium of the vagina, in the paravaginal ganglia, in the spinal cord and finally in the brain and in the adrenal glands. However, viral antigens could be demonstrated only in the medulla of the adrenal glands but not in the cortex, as assessed by immunohistochemistry (IHC). HSV could not be isolated from liver, spleen, uterus, and ovaries. This contrasts to the intraperitoneal (i.p) route of infection with replication in different visceral organs including the adrenal gland's cortex.

Motor action execution in reaction-time movements : Magnetoencephalographic study

2019

OBJECTIVE: Reaction-time movements are internally planned in the brain. Presumably, proactive control in reaction-time movements appears as an inhibitory phase preceding movement execution. We identified the brain activity of reaction-time movements in close proximity to movement onset and compared it with similar self-paced voluntary movements without external command. DESIGN: We recorded 18 healthy participants performing reaction-time and self-paced fast index finger abductions with 306-sensor magnetoencephalography and electromyography. Reaction-time movements were performed as responses to cutaneous electrical stimulation delivered on the hand radial nerve area. Motor field and movemen…

Anatomical and electrophysiological study of the vomeronasal circuits: Amygdaloid response to odours and pheromones

2017

Rodents detect information concerning the world around them mainly through two chemosensory systems: the olfactory and the vomeronasal systems. In order to develop an appropriate behavioural response to their environment, these systems exhibit both functional and physiological convergence. Further understanding of the organization and function of the olfactory systems would allow us to comprehend how their information is integrated in the brain. In a first approach we performed a thorough analysis of the connections of key structures involved in the processing of vomeronasal information: the medial (Me) and the posteromedial cortical (PMCo) amygdaloid nucleus. Then, we enquire the populatio…

Świętowanie na ulicy. Orszak Trzech Króli w zimowym pejzażu miasta

2017

Autorka zainteresowała się formami kolędniczymi, związanymi ze Świętem Trzech Króli (6 stycznia): tradycyjną grupą kolędniczą – Trzej królowie, nowszą – kolędnikami misyjnymi oraz organizowanym od 2009 r. na ulicach wielu miast w Polsce Orszakiem Trzech Króli, czyli oryginalną procesją uliczną. To hałaśliwe wydarzenie uliczne wpływa na odmienny charakter uczestniczenia w religijnym „misterium”: czytelny jest tu aspekt uteatralnienia ceremonii religijnej (przebrani aktorzy pierwszo- i drugoplanowi, rekwizytem powszechnym są papierowe korony królewskie, budowa scen, na których odbywają się koncerty amatorskich i profesjonalnych zespołów). Przemarsz ulicami miasta księży i osób wierzących, nau…
