INTRODUCTIONFournier's gangrene is a potentially fatal emergency condition, supported by an infection of perineal and perianal region, characterized by necrotizing fasciitis with a rapid spread to ...fascial planes. FG, usually due to compromised host, may be sustained by many microbial pathogens. CASE REPORTA 66-year-old man, with a history of uncontrolled type 2 diabetes, obesity with BMI 38, chronic kidney failure and chronic heart failure, was admitted to the Emergency Department with a large area of necrosis involving the perineal and perianal regions. DISCUSSIONFournier's gangrene is favoured by hypertension, obesity, chronic alcoholism, renal and heart failure. Generally, Fournier's gangrene needs other procedures in addition to wound debridement such as colostomy, cystostomy, or orchiectomy. CONCLUSIONWe report a case of FG found as complication in a patient with uncontrolled type 2 diabetes, treated with effective combination therapy with surgical debridement and antibiotics infusion.
Com o objetivo de obter uma equação que, por meio de parâmetros lineares dimensionais das folhas, permitisse a estimativa da área foliar de Panicum maximum, estudaram-se relações entre a área foliar ...real (Sf) e os parâmetros dimensionais do limbo foliar, como o comprimento ao longo da nervura principal (C) e a largura máxima (L), perpendicular à nervura principal. As equações lineares simples, exponenciais e geométricas obtidas podem ser usadas para estimação da área foliar. Do ponto de vista prático, sugere-se optar pela equação envolvendo apenas o produto C x L. Desse modo, a estimativa da área foliar de P. maximum pode ser feita pela fórmula Sf = 0,6058 x (C x L), que equivale a tomar 60,58% do produto entre o comprimento ao longo da nervura principal e a largura máxima, com coeficiente de determinação de 0,8586.The objective of this study was to obtain a mathematical equation to estimate the leaf area of Panicum maximum using linear measures of leaf blade. Correlation studies were conducted involving the real leaf area (Sf), the main vein leaf length (C), and the maximum leaf width (L). The linear and geometric equations related to C provided good leaf area estimates. For practical reasons, the use of an equation involving only the C*L product is suggested. Thus, an estimate of P. maximum leaf area can be obtained by the equation Sf = 0.6058 (C*L), with the coefficient of determination R = 0.8586.

The Time Projection Chamber (TPC) is an ideal candidate to finely study the charged particle ionization in a gaseous medium. Large volumes TPCs can be read out with a suitable number of channels ...offering a complete 3D reconstruction of an ultra-relativistic charged particle track, that is the sequence of its energy releases in the TPC gas volume. Moreover, He-based TPCs are very promising to study keV energy particles as nuclear recoils, opening the possibility for directional searches of Dark Matter (DM) and the study of Solar Neutrinos (SN). In this paper, we report the analysis of the data acquired with a small TPC prototype (named LEMOn) built by the CYGNO collaboration that was exposed to a beam of 450 MeV electrons at the Beam Test Facility of National Laboratories of Frascati. LEMOn is operated with a He-CF4 mixture at atmospheric pressure and is based on a Gas Electron Multipliers amplification stage that produces visible light collected by a sub-millimeter position resolution scientific CMOS camera. This type of readout - in conjunction with a fast light detection - allows a 3D reconstruction of the electrons' tracks. The electrons are leaving a trail of segments of ionizations corresponding to a few keV energy releases each. Their study leads to predict a keV energy threshold and 1-10 mm longitudinal and 0.1-0.3 mm transverse position resolution for nuclear recoils, very promising for the application of optically readout TPC to DM searches and SN measurements.
A scientist's recollection of his life as a junior member of the Manhattan Project, Rider of the Pale Horse recounts McAllister Hull's involvement in various nuclear-related enterprises during and ...after World War II. Fresh from a summer job working with explosives in the chemistry department of an ordnance plant, Hull was drafted in 1943, after his freshman year in college. Unlike other accounts written by scientists and historians of that era, Hull's narrative offers a realistic picture of the dangerous and messy job that GIs and civilian powder men were asked to do. Life in the workshops where bomb components were constructed was very different from life in the offices where they were designed. Hull's description of his postwar work supporting the Bikini Atoll tests in the Pacific and the early concerns about the effects of a hydrogen bomb explosion illuminate the Dark Age of nuclear weaponry. John Hull's handsome illustrations show technicians and scientists at work and bring the story to life. "Rider of the Pale Horse adds valuably to the total record of the most important technological development of the twentieth century."--Richard Rhodes, author of The Making of the Atom Bomb "Hull gives a bottom-up view as seen by a foot-soldier. His account of the grubby details of the project is illuminated by his later view of its historical repercussions and bears new witness to a turning-point of history." --Freeman Dyson, author of Disturbing the Universe
Using data collected by the FOCUS experiment at Fermilab, we present a new measurement of the charm semileptonic branching ratio BR(D+→ρ0μ+ν)BR(D+→K¯∗0μ+ν). From a sample of 320±44 and ...11372±161D+→ρ0μ+ν and D+→K−π+μ+ν events respectively, we find BR(D+→ρ0μ+ν)BR(D+→K¯∗0μ+ν)=0.041±0.006 (stat)±0.004 (syst).
