Validation of the German Version of the Music-Empathizing-Music-Systemizing (MEMS) Inventory (Short Version)
2018
Background: Kreutz et al. (2008) developed the Music-Empathizing-Music-Systemizing (ME-MS) Inventory to extend Baron-Cohen's cognitive style theory to the domain of music. We sought to confirm the ME-MS construct in a German sample and to explore these individual differences in relation to music preferences. Methods: The German adaptation of the MEMS Inventory was achieved by forward and backward translation. A total of 1014 participants (532 male, age: 33.79 ± 11.89 years) completed the 18-item short version of the MEMS Inventory online. Confirmatory factor analysis (CFA) was performed and cut-off values were established to identify individuals who could be classified as ME, Balanced, or M…
End-of-Life Care in High-Grade Glioma Patients. The Palliative and Supportive Perspective.
2018
High-grade gliomas (HGGs) are the most frequently diagnosed primary brain tumors. Even though it has been demonstrated that combined surgical therapy, chemotherapy, and radiotherapy improve survival, HGGs still harbor a very poor prognosis and limited overall survival. Differently from other types of primary neoplasm, HGG manifests also as a neurological disease. According to this, palliative care of HGG patients represents a peculiar challenge for healthcare providers and caregivers since it has to be directed to both general and neurological cancer symptoms. In this way, the end-of-life (EOL) phase of HGG patients appears to be like a journey through medical issues, progressive neurologic…
Topography of somatostatin gene expression relative to molecular progenitor domains during ontogeny of the mouse hypothalamus
2010
The hypothalamus comprises alar, basal, and floor plate developmental compartments. Recent molecular data support a rostrocaudal subdivision into rostral (terminal) and caudal (peduncular) halves. In this context, the distribution of neuronal populations expressing somatostatin (Sst) mRNA was analyzed in the developing mouse hypothalamus, comparing with the expression pattern of the genes Orthopedia (Otp), Distal-less 5 (Dlx5), Sonic Hedgehog (Shh), and Nk2 homeobox 1 (Nkx2.1). At embryonic day 10.5 (E10.5), Sst mRNA was first detectable in the anterobasal nucleus, a Nkx2.1-, Shh-, and Otp-positive basal domain. By E13.5, nascent Sst expression was also related to two additional Otp-positiv…
Germinal center B cells govern their own fate via antibody feedback
2013
High-affinity antibodies reenter germinal centers (GCs) and limit antigen access, thus causing sustained directional evolution in GCs toward higher-affinity antibody production.
Relaxation induced by N-terminal fragments of chromogranin A in mouse gastric preparations.
2007
Abstract A definitive role for chromogranin A (CGA)-derived fragments in the control of the gastrointestinal smooth muscle contractility has not been yet established. The purpose of the present study was to evaluate, in vitro , the effects of the recombinant vasostatin 1–78 (VS-1), CGA 7–57 and CGA 47–66 on the mouse gastric mechanical activity, recording the changes of intraluminal pressure. VS-1, CGA 7–57 and CGA 47–66 produced concentration-dependent relaxations. Mouse anti-vasostatin-1 monoclonal antibody 5A8, recognising the region 53–57, abolished the relaxation induced by VS-1, indicating the specificity of the effect. The relaxation was significantly reduced by tetrodotoxin (TTX), b…
Caracterización molecular de los receptores de gonadotrofinas de lubina (Dicentrarchus labrax)
2008
En los vertebrados, las gonadotrofinas (FSH y LH) son hormonas esenciales en el control de la gametogénesis y esteroidogénesis gonadal. Sus acciones están mediadas por la activación de sus respectivos receptores. A pesar de su importancia en la función reproductora, en teleósteos se dispone de muy poca información relativa a estos receptores. En este trabajo se investigaron las características moleculares, estructurales y funcionales de los receptores de gonadotrofinas (FSHR y LHR) de un teleósteo marino, la lubina (Dicentrarchus labrax). Además, se evaluó la especificidad de unión al ligando de estos receptores. Usando un método de RT-PCR cuantitativo, se midieron los perfiles de expresión…
The Inflammatory Feed-Forward Loop Triggered by the Complement Component C3 as a Potential Target in Endometriosis
2021
Copyright © 2021 Agostinis, Zorzet, Balduit, Zito, Mangogna, Macor, Romano, Toffoli, Belmonte, Morello, Martorana, Borelli, Ricci, Kishore and Bulla. The complement system is a major component of humoral innate immunity, acting as a first line of defense against microbes via opsonization and lysis of pathogens. However, novel roles of the complement system in inflammatory and immunological processes, including in cancer, are emerging. Endometriosis (EM), a benign disease characterized by ectopic endometrial implants, shows certain unique features of cancer, such as the capacity to invade surrounding tissues, and in severe cases, metastatic properties. A defective immune surveillance against…
Self-esteem, quality of life, and physical activity in women with diagnosed endometriosis: a pilot study in an Italian sample
2021
Purpose. Endometriosis is a painful pathology impairing women's daily life. Several studies have shown that patients report low mental and physical quality of life, but no general evaluation of their self-esteem has been found. Studies concerning physical activity frequency present inconsistent results. Therefore, the current paper aims to compare life quality and selfesteem in women with endometriosis with the Italian normative data of the measures used. Methods. Overall, 36 women with diagnosed endometriosis treated in hospital completed a questionnaire detecting physical activity frequency, self-esteem, quality of life, and socioeconomic information. One sample t-test served to compare t…
Caracterización de complejos enzimáticos histona acetiltransferasa en Saccharomyces cerevisiae mediante el uso de mutantes en genes implicados en la …
1999
En la cromatina de los organismos eucariotas el DNA se organiza alrededor de octámeros de histonas, dando lugar a la estructura nucleosomal. Las histonas sufren una serie de modificaciones postraduccionales entre las que se encuentra la acetilación de residuos de lisina, situados en los extremos N-terminales de estas proteínas. Esta modificación reversible, catalizada in vivo por las histona desacetilasas (HD) y las histona acetiltransferasas (HAT), ha sido implicada durante muchos años en la regulación de diversos procesos celulares de gran importancia. Recientemente, el papel de la acetilación de histonas en la regulación de la transcripción ha cobrado gran importancia con el descubrimien…
Estradiol deficiency and skeletal muscle apoptosis: Possible contribution of microRNAs.
2020
Background Menopause leads to estradiol (E2) deficiency that is associated with decreases in muscle mass and strength. Here we studied the effect of E2 deficiency on miR-signaling that targets apoptotic pathways. Methods C57BL6 mice were divided into control (normal estrous cycle, n = 8), OVX (E2 deficiency, n = 7) and OVX + E2 groups (E2-pellet, n = 4). Six weeks following the OVX surgery, mice were sacrificed and RNA isolated from gastrocnemius muscles. miR-profiles were studied with Next-generation sequencing (NGS) and candidate miRs verified using qPCR. The target proteins of the miRs were found using in silico analysis and measured at mRNA (qPCR) and protein levels (Western blot). Resu…
