Tensionless Limit of Pure-Ramond-Ramond Strings and AdS_{3}/CFT_{2}.

Despite impressive advances in the AdS_{3}/CFT_{2} correspondence, the setup involving Ramond-Ramond backgrounds, which is related to the D1-D5 system of branes, remained relatively poorly understood. We use the mirror thermodynamic Bethe ansatz (TBA) equations recently constructed by Frolov and Sfondrini to study the spectrum of pure Ramond-Ramond AdS_{3}×S^{3}×T^{4} strings. We find that the leading-order contribution to the anomalous dimensions at small tension is due to the gapless world-sheet excitations, i.

On the diagnosis of malignant pleural mesothelioma: A necropsy-based study of 171 cases (1997-2016).

Background: Malignant pleural mesothelioma (MPM) diagnosis is known to be difficult. We report on the diagnostic elements available in life in an MPM necropsy case series and describe the frequency of non-neoplastic asbestos-related diseases as biological exposure indices.

Methods: We reviewed pathologic and clinical records of an unselected series of autopsies (1977-2016) in patients with MPM employed in the Monfalcone shipyards or living with shipyard workers.

A genetic variant of NLRP1 gene is associated with asbestos body burden in patients with malignant pleural mesothelioma.

The presence of asbestos bodies (ABs) in lung parenchyma is considered a histopathologic hallmark of past exposure to asbestos fibers, of which there was a population of longer fibers. The mechanisms underlying AB formation are complex, involving inflammatory responses and iron (Fe) metabolism. Thus, the responsiveness to AB formation is variable, with some individuals appearing to be poor AB formers.

Iron signature in asbestos-induced malignant pleural mesothelioma: A population-based autopsy study.

Malignant pleural mesothelioma (MPM) is an aggressive cancer with poor prognosis. The development of MPM is frequently linked to inhalation of asbestos fibers. A genetic component of susceptibility to this disease is suggested by the observation that some individuals develop MPM following lower doses of asbestos exposure, whereas others exposed to higher quantities do not seem to be affected.

Primary pericardial mesothelioma in an asbestos-exposed patient with previous heart surgery.

We present a case of primary pericardial mesothelioma occurring in an asbestos-exposed 67-year-old man who underwent four aortocoronary bypass grafting seven years prior to the onset of the mesothelioma. Primary pericardial mesothelioma is a rare tumor whose association with asbestos is more infrequent than that of the much more common pleural form. Factors other than asbestos that may play a role include genetic predisposition, immune impairment, infections, radiation, dietary factors, and recurrent serosal inflammation.
