Abstract
A differential series is the normal method for identification of races within a plant pathogen and a host interaction. A host differential is extremely useful for phytopathological as well as breeding purposes. A set of recombinant inbred lines (RILs) were developed and characterized for race differentiation of Phytophthora root rot caused by Phytophthora capsici. The highly resistant Capsicum annuum accession Criollo de Morelos-334 was hybridized to a susceptible cultivar, Early Jalapeno, to generate the RIL population. The host differential characterized 17 isolates of P. capsici into 13 races. The establishment of a stable host differential for the P. capsici and C. annuum interaction will assist researchers in understanding the complex inheritance of resistance to Phytophthora root rot and to develop resistant cultivars.

Abstract
BACKGROUND A decompensated storage function with high pressures is the greatest risk factor regarding life expectancy and quality of life in patients with neurogenic detrusor hyperactivity. Previously, this problem could only be managed with administration of anticholinergic medications or--if this approach was either not effective enough or the patients exhibited drug intolerance--by invasive surgical interventions. The use of botulinum toxin type A to treat these patients rapidly proved to be a beneficial alternative to those two therapeutic options ever since its introduction in Germany in 1998 as a minimally invasive procedure and has become established worldwide. MATERIAL AND METHODS The medical records of first-time users at the clinic were retrospectively analyzed for a 7-year period. The total of 492 injections in 277 patients--of which 365 injections in 216 patients were performed following a standardized protocol--represents the largest number of cases worldwide. The treatment was indicated in patients experiencing insufficient efficacy of anticholinergic agents or drug intolerance who were capable of self-catheterization. RESULTS The standard injection contained either 300 MU Botox or 750 MU Dysport. Urodynamic parameters before and up to 8 months post-intervention showed significantly lowered detrusor pressure and improved cystometric capacity. This corresponded to the clinical assessment and subjective impression of the patients that detrusor activity had been reduced to a large extent with improved continence. Evacuation was carried out in all cases without any difficulty by aseptic intermittent catheterization. The average duration of the effect was subjectively determined to be 8.7 months. In the vast majority of cases, anticholinergic medications could be discontinued or considerably reduced. Side effects not requiring treatment developed in only four instances. Antibody formation no longer occurred with those products available on the market since 2001. Even after repeated injections (up to ten times) there was no evidence for decreased efficacy. CONCLUSION Due to its reliable effect and low rate of side effects, botulinum toxin type A quickly became accepted worldwide for the treatment of neurogenic detrusor hyperactivity and has contributed to a substantial enrichment of the more conservative therapy options. Prospective studies focusing especially on injection site and optimizing the duration of efficacy are desirable.

Abstract
OBJECTIVE Aim of this study was to evaluate the potential of denaturation of hormone active tissue in the thyroid gland by laser induced interstitial thermotherapy (LITT) as a treatment of autonomous hyperthyroidism. MATERIALS AND METHODS An interstitial thyroid laser application (Nd:YAG 1064 nm, 5W, 2 min) was performed in 5 pigs. During laser application, the laryngeal recurrent nerve was controlled electro-physiologically. Postoperatively, TSH, total T(3) (TT(3)) and free T(4) (FT(4)) were measured regularly. After a follow-up period of up to 6 weeks, pigs were sacrificed and the thyroid glands were evaluated histological. RESULTS A malfunction of the nerve due to laser treatment was not detected. During the first postoperative week there was a decrease of both FT(4) and TSH whereas TT(3) showed an extreme decline of its plasma levels reaching nearly the detection limit. All values showed a recovery to their initial levels during an interval of 10 days and than increased to levels sometimes higher than baseline. The coagulation zones were demarcated clearly towards normal tissue with increasing fibrosis of the treated areas. CONCLUSION Interstitial thyroid ablation using a Nd:YAG laser is a minimal invasive, safe and effective procedure. Further evaluation including long term follow-up in humans is needed to confirm these results.

Abstract
BACKGROUND AND PURPOSE We prospectively evaluated the influence of different imaging techniques (time-of-flight MR angiography [TOF-MRA], contrast-enhanced MR angiography [CE-MRA], multisection CT angiography [CTA]) and postprocessing methods (maximum intensity projection [MIP], multiplanar reformation [MPR]) on carotid artery stenosis grading. MATERIALS AND METHODS Fifty patients (34 men, 16 women) with symptomatic stenosis of the internal carotid artery were examined with a 16-section spiral CT and a 1.5T MR unit. Two MRA techniques were applied: 3D-TOF and CE-MRA. MPR was used for postprocessing with all modalities; MIP was used only with MRA. Four readers measured and calculated the percentage diameter stenosis independently according to NASCET criteria. The Wilcoxon test was used to measure interobserver variability, and the Friedman test was used to test the null-hypothesis of equality of the modalities. RESULTS The hypothesis for global equality was rejected (P < .001). TOF-MRA and CTA assessed with MPR showed the highest concordance (difference, 0.6%; confidence interval [CI], -3.0, 4.3%), and CE-MRA with MIP and CTA showed the lowest concordance in stenosis grading (difference, 7.0%; CI, 3.4, 10.6%). MPR resulted in lower degrees of stenosis than MIP for both MRA sequences, although not statistically significant (CE, -3.0%; CI, -6.6, 0.6%; TOF, -2.2%; CI, -5.8, 1.4%). When only studies with good or excellent image quality were considered, the differences decreased, but the trends remained. CONCLUSION Stenosis grading is dependent on the examination method and postprocessing technique. CTA and TOF-MRA evaluated with MPR revealed highest concordance.

Abstract
We used spectrally resolved fluorescence lifetime imaging (SLIM) to investigate the mitochondria staining dye rhodamine 123 and binding of DAPI to RNA and DNA in cells. Moreover, different components of the photosensitizer Photofrin were resolved in cell cultures by SLIM. To record lifetime images (tau-mapping) with spectral resolution we used a laser scanning microscope equipped with a spectrograph, a 16 channel multianode PMT, and multidimensional time-correlated single photon counting. A Ti:Saphir laser was used for excitation or alternatively a ps diode laser. With this system the time- and spectral-resolved fluorescence characteristics of different fluorophores were investigated in cell cultures. As an example, the mitochondria staining dye rhodamine I23 could be easily distinguished from DAPI, which binds to nucleic acids. Also different binding sites of DAPI could be discriminated. This was proved by the appearance of different lifetime components within different spectral channels. Moreover, we were able to detect monomeric and aggregated forms of Photofrin in cells. Different lifetimes could be attributed to the various compounds. In addition, a detailed analysis of the autofluorescence by SLIM could explain changes of mitochondrial metabolism during Photofrin-PDT.

Abstract
Low-intensity concentric (CET) and eccentric (EET) endurance-type training induce specific structural adaptations in skeletal muscle. We evaluated to which extent steady-state adaptations in transcript levels are involved in the compensatory alterations of muscle mitochondria and myofibrils with CET versus EET at a matched metabolic exercise intensity of medicated, stable coronary patients (CAD). Biopsies were obtained from vastus lateralis muscle before and after 8 weeks of CET (n=6) or EET (n=6). Transcript levels for factors involved in mitochondrial biogenesis (PGC-1alpha, Tfam), mitochondrial function (COX-1, COX-4), control of contractile phenotype (MyHC I, IIa, IIx) as well as mechanical stress marker (IGF-I) were quantified using an reverse-transcriptase polymerase chain reaction approach. After 8 weeks of EET, a reduction of the COX-4 mRNA level by 41% and a tendency for a drop in Tfam transcript concentration (-33%, P=0.06) was noted. This down-regulation corresponded to a drop in total mitochondrial volume density. MyHC-IIa transcript levels were specifically decreased after EET, and MyHC-I mRNA showed a trend towards a reduction (P=0.08). Total fiber cross-sectional area was not altered. After CET and EET, the IGF-I mRNA level was significantly increased. The PGC-1alpha significantly correlated with Tfam, and both PGC-1alpha and Tfam significantly correlated with COX-1 and COX-4 mRNAs. Post-hoc analysis identified significant interactions between the concurrent medication and muscular transcript levels as well as fiber size. Our findings support the concept that specific transcriptional adaptations mediate the divergent mitochondrial response of muscle cells to endurance training under different load condition and indicate a mismatch of processes related to muscle hypertrophy in medicated CAD patients.

Abstract
The conservative treatment of uterine fibroids is essentially based on symptomatology and patient's choice of treatment. The gynaecologist must develop a clear therapeutic protocol based on clinical examination, available test results and consideration of patient preference. The therapeutic options include close surveillance, hormonal treatments, conservative operative endoscopy and arterial embolization.
