As the integrity of graft endothelium seems to be essential to successful long-term patency in coronary operations, its preservation demands the utmost care. The aim of the present study was to investigate the effects of currently used solutions on endothelium-dependent relaxation after short-term storage of vessels at room temperature or at 4 degrees C. The infrarenal rat aorta was selected for s
Certain derivatives and analogues of capsazepine are potent in vitro inhibitors of bronchoconstriction in human small airways. During an investigation of the dependency of the potency on the structural features of the capsazepinoids in the thiourea moiety (coupling region) and the 2-(4-chlorophenyl)ethyl moiety (C-region), it was revealed that capsazepinoids with a thiourea or an amide link betwee
An assay has been established for quantitative evaluation of lentivirus coreceptor use with the help of GHOST(3) cells. GHOST(3) cells were derived from the human osteosarcoma cell line, HOS, and have been engineered to stably express CD4 and one or another of the chemokine receptors CCR3, CCR5, CXCR4, CXCR6/STRL33/Bonzo, or the orphan receptor GPR15/BOB. The indicator cell line carries the HIV-2
Well-rounded cobbles were encountered within a low-energy restricted marine organic-rich deposit of latest Cretaceous age in Chukotka, NE Asia. The clasts are hydrodynamically incompatible with the inferred quiet depositional environment of the host sediment. Driftwood capable of tree-rafting, glacial striations, gastrolith clast clustering, and disrupting clast impact impressions typical of volca
AIMS: The monophasic action potential (MAP) is conventionally recorded using Ag-AgCl electrodes which are not suitable for delivering radiofrequency currents. To be able to use the sharp MAP upstroke for identifying the local activation, as a step towards the development of a MAP-guided catheter ablation technique, the possibility of recording MAP via platinum electrodes of an ordinary ablation ca
Background. To determine the presence of Helicobacter species in the liver biopsy specimens from children with various chronic liver diseases as data in adult literature suggests a possible role of these bacteria in their pathogenesis.Materials and methods. Paraffin sections of 61 liver biopsies of pediatric patients with miscellaneous diseases and autopsy liver tissue from 10 control subjects wit
Angiomatoid fibrous histiocytoma (AFH) is a rare soft tissue tumor that usually occurs in children and young adults. Only two cases of AFH with genetic rearrangements have been reported previously; both of these had a FUS-ATF1 fusion gene. We have studied an AFH from a 9-year-old boy whose tumor displayed a t(12;22)(q13;q12) as the sole cytogenetic aberration. FISH,RT-PCR, and sequence analyses re
In the 1990s, two randomised clinical trials started in Scandinavia addressing whether hormone replacement therapy (HRT) is safe for women with previous breast cancer. We report the findings of the safety analysis in HABITS (hormonal replacement therapy after breast cancer-is it safe?), an open randomised clinical trial with allocation to either HRT or best treatment without hormones. The main end
The genetic polymorphism of Borrelia burgdorferi and Borrelia afzelii, two species that cause Lyme borreliosis, was estimated by sequence typing of four loci: the rrs-rrlA intergenic spacer (IGS) and the outer-membrane-protein gene p66 on the chromosome, and the outer-membrane-protein genes ospA and ospC on plasmids. The major sources of DNA for PCR amplification and sequencing were samples of the
Osteonecrosis of the femoral head following femoral neck fractures is a common condition. Spontaneous osteonecrosis, is, however, a rare disorder, which is observed with increased frequency in alcohol abusers. In this retrospective study, we followed 512 consecutive male patients who had sustained femoral neck fractures between 1984 and 1992; 82 of these 512 patients (16%) had earlier been registe
The minute problematic fossil Jinonicella kolebabai Pokorny 1978 is described from the Lower Silurian (Wenlock, middle Sheinwoodian) of the Nar-I core from southern Gotland. Growth lines indicate that the characteristic tubular snorkel of Jinonicella grew by envelopment of an emargination in the median dorsal aperture and not as a perforation through the dorsal surface of the shell. The direction
The official rhetoric of welfare states unconditionally pays tribute to older people’s right to express dissatisfaction. In practice, users of older services in welfare states may be deprived of their “exit” options and face considerable constraints when it comes to raising their “voices.” For example, when older people in nursing homes would like to lodge a complaint, they may well be referred to
Quantum chemical calculations have been performed on the ground state and several low-lying excited states of bromobenzene, ortho-, meta-, and para-dibromobenzene, and 1,3,5-tribromobenzene using high-level ab initio and hybrid density-functional methods. Experimental observations of ultrafast predissociation in these molecules are clarified from extensive theoretical information about all low-ene
The clinical evaluation section of the Core Assessment Program for Intracerebral Transplantations (CAPIT) for Parkinson's disease (PD) was developed to standardize the clinical evaluation in cell transplantation trials, but also has been used in other therapeutic trials for PD. An important part of the CAPIT protocol is the standardized timed tests of motor function. In a recent revision of CAPIT,
