Background: Lower respiratory tract infections (LRTI) are a common reason for consulting general practitioners (GPs). In most cases the aetiology is unknown, yet most result in an antibiotic prescription. The aetiology of LRTI was investigated in a prospective controlled study. Methods: Eighty adults presenting to GPs with acute LRTI were recruited together with 49 controls over 12 months. Thro...

Recently we reported that the expression of the protein kinase A (PKA) regulatory subunit RIIα is dynamically regulated in human smooth muscle cells of the uterus. We showed that expression levels of mRNA/protein were substantially increased during pregnancy and decreased upon labour, changes that were mirrored by particulate type II PKA activity. This implied an important role for RIIα in main...

The theory of Dirichlet forms as originated by Beurling-Deny and developed particularly by Fukushima and Silverstein, see e.g. [Fu3, Si], is a natural functional analytic extension of classical (and axiomatic) potential theory. Although some parts of it have abstract measure theoretic versions, see e.g. [BoH] and [ABrR], the basic general construction of a Hunt process properly associated with ...

Calcium aluminates (CA) are the most important hydraulically setting cements used for preparing refractory castables, because they develop high strength at very early ages after placements.  The anhydrous phases of this kind of cements are CA, CA2 and traces of C12A7 and alpha-alumina. The major hydraulic phase in all of the CA cements including ciment fondu...

Anastomosing haemangioma (AH) is a rare, benign variant of capillary usually occurring in the genitourinary system.1 AH easily confused with low-grade angiosarcoma2 due to its rarity, morphology, and identical radiological appearance. We present an unusual case incidentally found colon 55-year-old male. The patient underwent colonoscopy exclude microscopic colitis, 3 mm sessile rectal polyp was...

alfalfa (medicago sativa) is among a few of the most important forage crops for the growth of which hamedan province benefits from a suitable climate. alfalfa bacterial wilt disease induced by clavibacter michiganensis subsp. insidiosus cause substantial economic crop losses. this disease has not been so far investigated extensively in hamedan province. in the course of this survey affected pla...
