We revisit the Hartree-Fock (HF) calculation for the uniform electron gas, or jellium model, whose predictions--divergent derivative of the energy dispersion relation and vanishing density of states (DOS) at the Fermi level--are in qualitative disagreement with experimental evidence for simple metals. Currently, this qualitative failure is attributed to the lack of screening in the HF equations...

Malaria infections in pregnancy are associated with adverse outcomes for both mother and child. There are few data on hyper-reactive malarial splenomegaly, an aberrant immunological response to chronic or recurrent malaria in pregnancy. This retrospective assessment reviewed the impact of mefloquine treatment on pregnant women with suspected hyper-reactive malarial splenomegaly in an area of lo...

A one-step, large-scale preparation of alkyne-containing hyper-branched polyglycerols (HPG) is reported. The HPGs undergo click reactions to organic azides allowing a range of applications.

The Higgs branch of N = 2 supersymmetric gauge theories with nonAbelian gauge groups are described by hyper-Kähler (HK) nonlinear sigma models with potential terms. With the non-Abelian HK quotient by U(M) and SU(M) gauge groups, we give the massive HK sigma models that are not toric in the N = 1 superfield formalism and the harmonic superspace formalism. The U(M) quotient gives N !/[M !(N −M)!...

Mevalonate kinase deficiency (MKD) is a rare autosomal recessive disorder causing 1 of 2 phenotypes, hyperimmunoglobulin D syndrome and mevalonic aciduria, presenting with recurrent fever episodes, often starting in infancy, and sometimes evoked by stress or vaccinations. This autoinflammatory disease is caused by mutations encoding the mevalonate kinase (MVK) gene and is classified in the grou...

OBJECTIVES To review the management of primary immunodeficiency and discuss recent advances in genetic analysis. DESIGN Retrospective study. SETTING University teaching hospital, Hong Kong. PATIENTS Children diagnosed with primary immunodeficiency and followed up in the immunology clinic during the period 1988 to 2003. MAIN OUTCOME MEASURES Demographic data, co-morbidities and treatment...

Hemophagocytic lymphohistiocytosis is character-ized by fever, hepatosplenomegaly, cytopenia, hyper-triglyceridemia, hypofibrinogenemia, and hemophago-cytosis. Ascites is not mentioned as a symptom of hemophagocytic syndrome. We report a one month-old girl suffering from familial erythrophagocytic lympho-histiocytosis, who presented with ascites.
