INTRODUCTION Dentin hypersensitivity (DH) is a painful tooth condition affecting a large proportion of the world population. While DH is not a direct cause of tooth loss, it does cause discomfort and stress. DH treatment methods include desensitizers, such as fluoride compounds; polycyanoacrylate coating; low intensity laser therapy; and surgery as a last resort. In Cuba, a fluoride varnish, Pr...

The synthesis of a new series of mixed phenylene-thiophene oligomers is reported; 2,5-bis(4-n-hexylphenyl)thiophene (dH-PTP, 1), 5,5'-bis(4-n-hexylphenyl)-2,2'-bithiophene (dH-PTTP, 2), 5,5' '-bis(4-n-hexylphenyl)-2,2':5',2' '-terthiophene (dH-PT(3)P, 3), 5,5' "-bis(4-n-hexylphenyl)-2,2':5',2' ':5' ',2' "-quaterthiophene (dH-PT(4)P, 4), 1,4-bis[5-(4-n-hexylphenyl)-2-thienyl]benzene (dH-PTPTP, 5...

Using diagnostic criteria which are currently accepted as most reliable we have found that 19% (9/47) of patients with dermatitis herpetiformis (DH) have no evidence of coeliac disease. The incidence of HL-A8 in the DH patients was 78%, which is considerably greater than that in healthy controls and no different from that reported in coeliac disease. Furthermore, the incidence of HL-A8 was just...

DH: dermatitis herpetiformis DIF: direct immunofluorescence EED: erythema elevatum diutinum INTRODUCTION Dermatitis herpetiformis (DH) is a cutaneous manifestation of gluten intolerance characterized by an intensely pruritic, papulovesicular eruption with a predilection for the extensor extremities, scalp, and buttocks. Because of its variable clinical presentation, DH can be a challenging clin...

A subgroup of patients with type 2 diabetes shows a clustering of abnormalities such as peripheral insulin resistance, hypertension, and microalbuminuria. To evaluate whether these traits reflect intrinsic disorders of cell function rather than in vivo environmental effects, we studied a group of 7 nondiabetic hypertensive subjects with an altered albumin excretion rate (AER) (HyMA+) and 3 grou...

The prompt recognition of the clinical features of dermatitis herpetiformis (DH) is important, but securing a definitive diagnosis requires further work-up. Recent advances in understanding of the immunologic basis for DH have led to the development and wider availability of serologic testing, which is rapidly becoming an essential part of the diagnosis and management of DH. Part II of this ser...

We measure the propagator length in imaginary time quantum mechanics by Monte Carlo simulation on a lattice and extract the Hausdorff dimension dH . We find that all local potentials fall into the same universality class giving dH = 2 like the free motion. A velocity dependent action (S ∝ ∫ dt | ~v |α) in the path integral (e.g. electrons moving in solids, or Brueckner’s theory of nuclear matte...

The performance of dual heard pulse interval modulation (DH-PIM) employing least mean square error equaliser (LMSE) in diffuse infrared indoor environment is presented. The work is based on the ceiling bounce channel model and the Monte Carlos simulation. A 3-tap LMSE equaliser is used and results are compared with unequalised DH-PIM and with DH-PIM employing linear zero forcing equaliser (L-ZF...

Guanine nucleotide exchange factors for the Rho family of GTPases contain a Dbl homology (DH) domain responsible for catalysis and a pleckstrin homology (PH) domain whose function is unknown. Here we describe the solution structure of the N-terminal DH domain of Trio that catalyzes nucleotide exchange for Rac1. The all-alpha-helical protein has a very different structure compared to other excha...

Any real number x in the unit interval can be expressed as a continued fraction x = [n1, ..., nN , ...]. Subsets of zero measure are obtained by imposing simple conditions on the n N . By imposing n N ≤ m ∀ N ∈ IN , Jarnik defined the corresponding sets Em and gave a first estimate of dH(Em), dH the Hausdorff dimension. Subsequent authors improved these estimates. In this paper we deal with dH(...
