Sebaceous hyperplasia
No full textCrown vessels are typically seen in sebaceous hyperplasia and are characterized by elongated, blurred telangiectases that embrace centrally located white to yellow lobular structureless areas. The vessels do not usually cross over the central portions of the lesion, and they reveal a radial arrangement. The main differential diagnosis of sebaceous hyperplasia is basal cell carcinoma. The different vascular patterns and vessels arrangements are important clues that help in the distinction between these two entities. More specifically, the branching or arborizing vessels of nodular basal cell carcinoma are bright red, are sharply focused, and often course over the central part of the lesion. Conversely, sebaceous hyperplasia is typified by the presence of crown-like vessels located around the periphery of the lesion that are less bright red and are blurred compared to the vessels observed in basal cell carcinoma

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Home-making. Tra ricordi e proiezioni del futuro
No full textDagli anni Sessanta del Novecento, in Olanda, si è sempre più diffusa
tra i giovani l’abitudine di andare a vivere da soli, nel momento in cui
decidevano di lasciare la casa di famiglia. Vivere da soli per un certo
periodo prima di un matrimonio o una convivenza è oggi considerata
un’esperienza positiva rispetto alla possibilità di sviluppare una personalità
equilibrata, indipendente e matura. Ma alcuni decenni fa sposarsi era
la sola opzione legittima per coloro che volessero dare vita a un nucleo
abitativo indipendente. Mentre i conflitti tra genitori, figli e figlie, basati
su questioni relative allo stile di vita avevano motivato il distacco dalla casa
di famiglia delle generazioni degli anni Sessanta e dei primi anni Settanta,
all’inizio del secondo millennio la motivazione principale sembra piuttosto
essere connessa al desiderio dei giovani di più privacy e indipendenza
Verso la città gastrocratica? Nuove identità per i mercati alimentari
No full textIl mercato tradizionale è comunemente inteso come uno spazio circoscritto
e relativamente poco progettato al proprio interno dove si realizza un
tipo di scambio di merci mediato dalla creatività e dall’intraprendenza
di commercianti artigiani di fronte a un pubblico di clienti incontrati de
visu. Da qualche decennio questo tipo di spazio commerciale sta andando
incontro a significative innovazioni (organizzative, merceologiche,
architettoniche, di pratica) che ne mutano buona parte del carattere,
come vedremo anche in questo saggio. Come conseguenza, il mercato
sta riscuotendo un rinnovato interesse nell’ambito delle politiche urbane.
Come per lo studio di altri tipi di spazi commerciali (ad esempio, Miller,
Jackson e Rowlands 1998), è interessante comprendere come le risorse
materiali e sociali dei mercati siano rimesse in gioco da una serie di
pratiche eterogenee che essi stimolano: da quelle dell’andar per compere
al loro interno o nel quartiere circostante o persino in altre città, a quelle
stimolate dalle politiche che li interessano, alle pratiche di tipo progettuale-architettonico
Binge drinking and inhibitory control: a mini-review of fMRI studies
No full textINTRODUCTION: Binge drinking (BD) refers to the intake of a high level of alcohol in a limited amount of time followed by a period of reduction or absence of alcohol consumption. Given the increase of BD during adolescence, understanding the potentially dangerous effects of consuming large amounts of alcohol on neural circuitry and cognitive status has public health and social importance. From a cognitive point of view, excessive alcohol intake at a young age can affect executive functions and, in particular, inhibitory control capacity. This, in turn, further reduces the ability to inhibit seeking and consuming alcohol at risky levels, up to the establishment of alcohol use disorders (AUD). Therefore, in this review, we describe current evidence from functional magnetic resonance imaging (fMRI) studies that examined functional circuits associated with inhibitory control in binge drinkers.EVIDENCE ACQUISITION: The literature search retrieved 43 articles. After titles and abstracts screening, 30 records were excluded as they did not meet the inclusion criteria. Ten additional records were excluded after full-text review, while three studies were identified and include in this systematic mini-review.EVIDENCE ACQUISITION: Preliminary fMRI findings show increased activations in binge versus light drinkers during inhibitory control tasks (especially during incongruent conditions) in frontoparietal areas.CONCLUSIONS: In line with the continuum hypothesis, the results suggest that binge drinkers and individuals with AUD share functional brain alterations in regions ascribed to inhibitory control processes, reinforcing the hypothesis that BD and AUD may be considered two successive stages of the same phenomenon. Nontheless, longitudinal studies, in larger and better-characterized samples of binge and light drinkers, are needed to disentangle the role of inhibitory control processes in the development and maintenance of BD patterns.
