Behavior of borderline tumors with particular interest to persistence, recurrence, and progression to invasive carcinoma: a prospective study

Abstract: PURPOSE: Borderline tumors account for 10% to 20% of epithelial ovarian tumors, and their prognosis is outstanding; nevertheless, a mortality of up to 20% has been reported, particularly in earlier reports. There is a lack of information about the actual mortality and the rate of progression into invasive carcinoma in large and prospectively accrued populations. PATIENTS AND METHODS: All women with borderline ovarian tumors undergoing primary surgery in our department or referred within 3 months from surgery performed elsewhere from 1982 to 1997 were prospectively accrued and observed. RESULTS: We studied 339 women (83.4% stage I, 7.9% stage II, and 8.5% stage III). The median age at diagnosis was 39 years. A total of 150 women underwent radical surgery, and 189 underwent fertility-sparing surgery. After surgery, 13 women had macroscopic residual disease. With a median follow-up of 70 months, 317 women are alive with no clinical disease (eight with documented subclinical persistence of implants), three ar...

A topologically twisted index for three-dimensional supersymmetric theories

Abstract: We provide a general formula for the partition function of three-dimensional $$ \mathcal{N}=2 $$ gauge theories placed on S2 ×S1 with a topological twist along S2, which can be interpreted as an index for chiral states of the theories immersed in background magnetic fields. The result is expressed as a sum over magnetic fluxes of the residues of a meromorphic form which is a function of the scalar zero-modes. The partition function depends on a collection of background magnetic fluxes and fugacities for the global symmetries. We illustrate our formula in many examples of 3d Yang-Mills-Chern-Simons theories with matter, including Aharony and Giveon-Kutasov dualities. Finally, our formula generalizes to Ω-backgrounds, as well as two-dimensional theories on S2 and four-dimensional theories on S2 × T 2. In particular this provides an alternative way to compute genus-zero A-model topological amplitudes and Gromov-Witten invariants.

The sympathetic nervous system and the metabolic syndrome.

Abstract: Studies performed in the past two decades have unequivocally shown that several of the components of the metabolic syndrome are associated with indirect and direct markers of adrenergic overdrive. This is the case for hypertension and obesity, in which resting tachycardia, elevated plasma norepinephrine values, increased sympathetic nerve traffic, as well as augmented levels of total and regional norepinephrine spillover have been reported. This is also the case for insulin resistance, i.e. a metabolic condition frequently complicating the various components of the pathological condition identified as the 'metabolic syndrome'. After briefly describing the epidemiological and the cardiovascular risk profile of the disease, this paper will examine the behaviour of the sympathetic nervous system in the metabolic syndrome as well as the mechanisms potentially responsible for this neurogenic abnormality. This will be followed by an analysis of the role played by neuroadrenergic factors in disease progression as well as in the pathogenesis of its complications. Finally, the therapeutic implications of these findings will be highlighted.

Differential branching fractions and isospin asymmetries of B -> K ((*)) μ(+) μ(-) decays

Abstract: The isospin asymmetries of B -> K mu (+) mu (-) and B -> K (*) mu (+) mu (-) decays and the partial branching fractions of the B (0) -> K (0) mu (+) mu (-), B (+) -> K (+) mu (+) mu (-) and B (+) -> K (*+) mu (+) mu (-) decays are measured as functions of the dimuon mass squared, q (2). The data used correspond to an integrated luminosity of 3 fb(-1) from proton-proton collisions collected with the LHCb detector at centre-of-mass energies of 7 TeV and 8 TeV in 2011 and 2012, respectively. The isospin asymmetries are both consistent with the Standard Model expectations. The three measured branching fractions favour lower values than their respective theoretical predictions, however they are all individually consistent with the Standard Model.
