Factitial dermatitis is a condition in which skin lesions are self-inflicted as the result of a psychiatric disorder. The lesions may be presented in various forms and produced by a wide variety of means. This report refers to the case of a patient with factitial dermatitis triggered by Munchausen syndrome, which refers to individuals who intentionally provoke physical symptoms in themselves in...

It has been shown recently that the Higgs doublet may be composite, with the left-handed top-bottom doublet and a new right-handed anti-quark as constituents bound by some four-quark operators with non-perturbative coefficients. I show that these operators are naturally induced if there are extra spatial dimensions with a compactification scale in the multi-TeV range. The Higgs compositness is ...

Editor's Note: These short, critical reviews of recent papers in the Journal, written exclusively by graduate students or postdoctoral fellows, are intended to summarize the important findings of the paper and provide additional insight and commentary. For more information on the format and purpose of the Journal Club, please see Review of Abisambra et al. The endoplasmic reticulum (ER) is a si...

Since the 1980s, the occurrence of pertussis cases in developed countries has increased and shifted towards older age groups. This resurgence follows 30 years of intense mass vaccination, and has been attributed primarily to three factors: (1) more effective diagnosis of the disease, (2) waning of vaccine-induced immunity, and (3) loss of vaccine efficacy due to the emergence of new Bordetella ...

arch-ive/9504055 We consider Clifford algebras with nonsymmetric bilinear forms, which are isomorphic to the standard symmetric ones, but not equal. Observing, that the content of physical theories is dependent on the injection ⊕ ∧ V(n) → CL(V, Q) one has to transform to the standard construction. The injection is of course dependent on the antisymmetric part of the bilinear form. This process ...

1 of 2 DESCRIPTION A previously healthy 22-year-old gentlemen was referred to the surgical department following acute onset epigastric pain. The initial onset of pain was followed by an episode of vomiting and wretching lasting an hour. On examination, although the abdomen was tender in the epigastrium there was no evidence of peritonitis. Crepitus was evident in the neck and anterior chest wal...

Chylous ascites (chyloperitoneum) is a rare clinical condition, characterized by an accumulation of lymph fluid in the peritoneal cavity. Most commonly it is associated with abdominal malignancy (usually lymphoma). We present an unusual case of a woman who developed a persistent pseudocyst and recurrent chylous ascites following acute necrotizing pancreatitis.

DNA damage observed during plant immune responses is reported to be an intrinsic component of plant immunity. However, other immune responses may suppress DNA damage to maintain host genome integrity. Here, we show that immunity-related DNA damage can be abrogated by preventing cell death triggered by Nucleotide-binding, Leucine-rich-repeat immune Receptors (NLRs). SNI1 (suppressor of npr1-1, i...

Male and female homosexuality have substantial prevalence in humans. Pedigree and twin studies indicate that homosexuality has substantial heritability in both sexes, yet concordance between identical twins is low and molecular studies have failed to find associated DNA makers. This paradoxical pattern calls for an explanation. We use published data on fetal androgen signaling and gene regulati...
