To the Editor: Hospital and public health personnel are currently receiving smallpox vaccination in a national effort to increase preparedness for a possible deliberate release of smallpox (1). Generalized vaccinia (GV) is a typically self-limited adverse event following vaccination (incidence 23.4–238.2 cases per million primary vaccinees and 1.2–10.8 cases per million revaccinees) (2,3). We r...

1. Fragments of skin from the leopard frog (Rana pipiens) were cultivated in media of varying consistency. A mixture of frog plasma, frog muscle extract, chicken plasma, and chicken embryo extract usually produced a very firm medium; a mixture of frog plasma, frog muscle extract, and chicken plasma, one less firm (semi-firm); and a mixture of frog plasma and frog muscle extract a medium of a co...

Whole-body magnetic resonance imaging (MRI) is a diagnostic tool that enables the visualization of the entire body and combines fast acquisition times with high contrast resolution. An important advantage of this technique is the absence of ionizing radiation. Thus, whole-body MRI offers a radiation-free alternative to radionuclide imaging and CT for the diagnosis, staging, and monitoring of yo...

Parkes-Weber syndrome (PWS) is an arteriovenous vascular malformation. It occurs at birth and affects mainly the lower limbs (77%). Detection of arteriovenous fistula associated with the Klippel-Trénaunay syndrome (KTS) triad confirms the diagnosis of this syndrome. (1, 2) The KTS is characterized by the typical triad of cutaneous vascular port wine stains, soft tissue and/or bone hypertrophy a...

Tissue homeostasis is ensured by the correct balance between cell proliferation and death, the latter mainly occurring through a multi-step program, named apoptosis, which ultimately leads to the breakdown of cellular DNA and proteins. Apoptosis is activated under physiological developmental conditions, during metamorphosis and atrophy of tissues and organs, sexual differentiation and cell turn...

Cactus in four populations of saguaros (Carnegiea gigantea) that were damaged in a 1987 hailstorm were measured, and the heights of individuals in 1987 and 2003 were obtained trigonometrically. Net growth in this 16-year interval ranged from 0.15-3.00 m across the 300 saguaros measured, and averaged 1.03-1.48 m across the four sites. Average cactus height in both years, as well as net growth, d...

This article proposes a revision of the predominant view of southern Italians during the ‘Hot Autumn’ of 1969 in Turin, one of the most remarkable moments of working-class mobilisation in modern European history. The representation of southern Italians as ‘primitive rebels’ and ‘spontaneous’ radicals has its roots in an earlier notion of southerners as social deviants and has obscured a much mo...
