BACKGROUND Primary aldosteronism (PA) is the most common endocrine form of secondary hypertension, and one of the most common subtypes of sporadic PA is aldosterone-producing adenoma (APA). Recently, two somatic mutations of the KCNJ5 gene were implicated in APA, and two germline mutations were associated with familial hyperaldosteronism III. OBJECTIVES This case-control study was designed to...

myelodysplastic syndrome (mds), is a group of heterogeneous disorders of hematopoietic stem cell colonies which is determined by incomplete hematopoiesis in one or more cell lines. the incidence increases with age and it has less been reported among patients under 50 years of age. the commonest form of mds is sporadic, and familial occurrence of mds is rare. patients with familial mds are young...

During the past ten years there has been a steadily increasing interest in the typhuslike fevers which occur sporadically in many parts of the world. It is now evident that this disease group is of considerable importance, not only because of the frequency with which people are affected, but also because of the difficulties which arise in connection with the diagnosis, and the mystery which att...

In this paper we complete the Brauer trees for the sporadic simple Lyons group Ly in characteristics 37 and 67. The results are obtained using tools from computational representation theory, in particular a new condensation technique, and with the assistance of the computer algebra systems MeatAxe and GAP.

This is an introduction to finite simple groups, in particular sporadic groups, intended for physicists. After a short review of group theory, we enumerate the 1 + 1 + 16 = 18 families of finite simple groups, as an introduction to the sporadic groups. These are described next, in three levels of increasing complexity, plus the six isolated “pariah” groups. The (old) five Mathieu groups make up...

Patients with adult onset non-familial progressive ataxia are classified in sporadic ataxia group. There are several disease categories that may manifest with sporadic ataxia: toxic causes, immune-mediated ataxias, vitamin deficiency, infectious diseases, degenerative disorders and even genetic conditions. Considering heterogeneity in the clinical spectrum of sporadic ataxias, the correct diagn...

We introduce the notion of vertex operator superalgebra with enhanced conformal structure, which is a refinement of the notion of vertex operator superalgebra. We exhibit several examples, including a particular one which is self-dual, and whose full symmetry group is a direct product of a cyclic group of order seven with the sporadic simple group of Rudvalis. We thus obtain an analogue of Mons...
