Purpose: Androgen deprivation therapy (ADT) is a cornerstone in prostate cancer (PCa) management that prolongs PCa-free and overall survival, but effects of ADT on human cardiac function have not been investigated. We used echocardiography to examine cardiac structure and function in patients with prostate cancer receiving ADT and to determine whether an exercise intervention can elicit cardiac adaptations in these subjects. Methods: Forty-three patients with prostate cancer receiving ADT were randomized to 12 weeks football training (ST group;n = 20) or usual care (control [CO] group;n = 23). Cardiac function was assessed at baseline and after 12 weeks by comprehensive echocardiography. Peak oxygen consumption, blood pressure and peripheral microvascular function was also measured. Results: At baseline, no considerable echocardiographic abnormalities were observed. In the ST group, increases in left ventricular diastolic function variables including E/A ratio (P = 0.03), E’ (P = 0.016), E’TDIcolor (P = 0.040) and in left atrial diameter (P = 0.001) were observed after 12 weeks. In addition, diastolic blood pressure (P = 0.027) and resting heart rate (P 0.001) were reduced after ST. In the CO group, no significant changes were observed in the examined variables after 12 weeks. Despite within group changes in the ST group, no significant differences were observed after 12 weeks between groups in echocardiographic variables, peak oxygen consumption, blood pressure and peripheral microvascular function. Conclusion: In men with prostate cancer receiving ADT, echocardiography showed no abnormalities in cardiac structure and function. Twelve weeks of ST failed to elicit significant cardiovascular adaptations and ADT may blunt cardiovascular adaptations to short-term exercise training.

Objectives: To determine the clinical outcome related to treatment failure of the percutaneous coronary intervention (PCI) itself. Background: When considering the addition of PCI to the medical treatment of angina, it is necessary to know the balance between the benefit and the risk of the PCI itself, but the latter remains unknown. The usual outcome measures are imprecise because they contain events unrelated to the previous PCI and because some events clearly caused by PCI treatment failures are omitted. Methods: In total, 2098 unselected patients were randomized to receive either sirolimus-(n = 1065) or paclitaxel-(n = 1033) eluting coronary stents and followed for five years in the SORT OUT II. Any death, cardiac death, myocardial infarction (MI), stent thrombosis and documented stenosis was classified and combined to a “patient oriented clinical outcome” (POCO), the classical “major adverse cardiac events” (MACE) and the new “PCI-treatment oriented clinical outcome” (TOCO). Results: POCO occurred in 746 patients (35.6%), MACE in 467 patients (22.3%) and TOCO in 293 patients (14.0%), thus TOCO amounted to 39% of the POCO and to 63% of the MACE. Conclusion: By introduction of the present PCI treatment failure classification system, the clinical outcome of PCI-treatment itself may be credulously estimated by the rate of TOCO and eventually PCI is substantially better than what might be perceived from the classically used POCO and MACE rates.

Background In beef cattle, more than 50% of the energy input to produce a unit of beef is consumed by the female that produced the calf. Development of genomic tools to identify females with high genetic merit for reproductive function could increase the profitability and sustainability of beef *** Genome-wide association studies(GWAS) were performed using a single-step genomic best linear unbiased prediction approach on pregnancy outcome traits from a population of Angus–Brahman crossbred heifers. Furthermore, a validation GWAS was performed using data from another farm. Heifers were genotyped with the Bovine GGP F250 array that contains 221,077 SNPs. In the discovery population, heifers were bred in winter breeding seasons involving a single round of timed artificial insemination(AI) followed by natural mating for 3 months. Two phenotypes were analyzed: pregnancy outcome to first-service AI(PAI;n = 1,481) and pregnancy status at the end of the breeding season(PEBS;n = 1,725). The heritability was estimated as 0.149 and 0.122 for PAI and PEBS, respectively. In the PAI model, one quantitative trait locus(QTL), located between 52.3 and 52.5 Mb on BTA7, explained about 3% of the genetic variation, in a region containing a cluster of γ-protocadherin genes and SLC25A2. Other QTLs explaining between 0.5% and 1% of the genetic variation were found on BTA12 and 25. In the PEBS model, a large QTL on BTA7 was synonymous with the QTL for PAI, with minor QTLs located on BTA5, 9, 10, 11, 19, and 20. The validation population for pregnancy status at the end of the breeding season were Angus–Brahman crossbred heifers bred by natural mating. In concordance with the discovery population, the large QTL on BTA7 and QTLs on BTA10 and 12 were *** In summary, QTLs and candidate SNPs identified were associated with pregnancy outcomes in beef heifers, including a large QTL associated with a group of protocadherin genes.

A rare diagnosis:testicular dysgenesis with carcinoma in situ detected in a patient with ultrasonic microlithiasis

引用

Asian Journal of Andrology 2005年第4期7卷 445-447,页

作者： Christina E.Hoei-hansen peter Sommer Ewa Rajpert-De Meyts Niels E.Skakkebaek Department of Growth and Reproduction Department of Urology University Hospital of Rigshospitalet2100 Copenhagen Denmark

A rare case is presented where a dysgenetic testis with microinvasive carcinoma in situ （CIS, also known as intratubular germ cell neoplasm of unclassified type [IGCNU] and testicular intraepithelial neoplasia [TIN]） with microinvasion to rete testis and the interstitial tissue was found in a 32-year-old man presenting with mild scrotal pain and ultrasonic testicular microlithiasis. Knowledge of the association of ultrasound and CIS is important to diagnose patients at the stage prior to development of an overt germ cell tumor. The patient had three of four disorders considered symptoms of the testicular dysgenesis syndrome （TDS）： a dysgenetic left testicle with CIS, a mild left-sided cryptorchidism （high positioned scrotal hypotrophic testis） and a slightly reduced semen quality. Therefore, it should be kept in mind that a patient with one TDS symptom may harbour the other, even CIS or testicular cancer. Accordingly, patients with one TDS symptom ought to be examined for the presence of the others, and if more that one is present, extra concern is warranted.

Sildenafil does not influence hepatic venous pressure gradient in patients with cirrhosis

引用

World Journal of Gastroenterology 2008年第40期14卷 6208-6212页

作者： Jens Otto Clemmesen Annamaria Giraldi peter Ott Kim Dalhoff Bent Adel hansen Fin Stolze Larsen Department of Hepatology RigshospitaletUniversity Hospital of Copenhagen Clinical Pharmacology RigshospitaletUniversity Hospital of Copenhagen

AIM： To investigate if sildenafil increases splanchnic blood flow and changes the hepatic venous pressure gradient （HVPG） in patients with cirrhosis. Phosphodiesterase type-5 inhibitors are valuable in the treatment of erectile dysfunction and pulmonary hypertension in patients with end-stage liver disease. However, the effect of phosphodiesterase type-5 inhibitors on splanchnic blood flow and portal hypertension remains essentially unknown. METHODS： Ten patients with biopsy proven cirrhosis （five females/five males, mean age 54：1：8 years） and an HVPG above 12 mmHg were studied after informed consent. Measurement of splanchnic blood flow and the HVPG during liver vein catheterization were done before and 80 min after oral administration of 50 mg sildenafil. Blood flow was estimated by use of indocyanine green clearance technique and Fick＇s principle, with correction for non-steady state. RESULTS： The plasma concentration of sildenafil was 222 ± 136 ng/mL 80 min after administration. Mean arterial blood pressure decreased from 77 ±7 mmHg to 66 ± 12 mmHg, P = 0.003, while the splanchnicblood flow and oxygen consumption remained unchanged at 1.14 ± 0.71 L/min and 2.3 ± 0.6 mmol/ min, respectively. Also the HVPG remained unchanged （18 ± 2 mmHg vs 16 ± 2 mmHg） with individual changes ranging from -8 mmHg to ±2 mmHg. In seven patients, HVPG decreased and in three it increased. CONCLUSION： In spite of arterial blood pressure decreases 80 min after administration of the phosphodiesterase type-5 inhibitor sildenafil, the present study could not demonstrate any clinical relevant influence on splanichnic blood flow, oxygen consumption or the HVPG.

Auxin homeostasis is pivotal for normal plant growth and development. The superroot2 （sur2） mutant was initially isolated in a forward genetic screen for auxin overproducers, and SUR2 was suggested to control auxin conju- gation and thereby regulate auxin homeostasis. However, the phenotype was not uniform and could not be described as a pure high auxin phenotype, indicating that knockout of CYP83B1 has multiple effects. Subsequently, SUR2 was identified as CYP83B1, a cytochrome P450 positioned at the metabolic branch point between auxin and indole glucosinolate metabolism. To investigate concomitant global alterations triggered by knockout of CYP83B1 and the countermeasures chosen by the mutant to cope with hormonal and metabolic imbalances, 10-day-old mutant seedlings were characterized with respect to their transcriptome and metabolome profiles. Here, we report a global analysis of the sur2 mutant by the use of a combined transcriptomic and metabolomic approach revealing pronounced effects on several metabolic grids including the intersection between secondary metabolism, cell wall turnover, hormone metabolism, and stress responses. Metabolic and transcriptional cross-talks in sur2 were found to be regulated by complex interactions between both positively and negatively acting transcription factors. The complex phenotype of sur2 may thus not only be assigned to elevated levels of auxin, but also to ethylene and abscisic acid responses as well as drought responses in the absence of a water deficiency. The delicate balance between these signals explains why minute changes in growth conditions may result in the non-uniform phenotype. The large phenotypic variation observed between and within the different surveys may be reconciled by the complex and intricate hormonal balances in sur2 seedlings decoded in this study.

Rose Hip Powder That Contains the Natural Amount of Shells and Seeds Alleviates Pain in Osteoarthritis of the Dominant Hand—A Randomized, Double-Blind, Placebo-Controlled, Cross-Over Clinical Trial

引用

Open Journal of Rheumatology and Autoimmune Diseases 2013年第3期3卷 172-180页

作者： Kaj Winther Joan Campbell-Tofte peter hansen Department of Clinical Biochemistry Coordinating Research Unit Frederiksberg University Hospital Frederiksberg Denmark.

Aim: A standardized preparation of seeds and shells of selected sub-species of Rosa canina L, trade name Hyben Vital, reduces discomfort from osteoarthritis of the knee and hip. This study aims to investigate the impact of the same rose-hip powder (RHP) on discomfort and the consumption of rescue medication, in patients with osteoarthritis of the hand. Methods: The double blind, placebo-controlled, crossover trial included 30 patients with osteoarthritis of the dominant hand. Patients were randomly allocated to treatment with either five gram encapsulated RHP or placebo, for three months (Phase 1), after which they switched to the corresponding treatment for a further three months period (Phase 2). Before entering the study, after 3 weeks and following three months of each of the study phases, scores for pain, stiffness and general feeling of discomfort were evaluated using a 10 step categorical scale, focusing on 16 different daily activities of the hand. The consumption of rescue medication was also calculated at the beginning and at the end of each study phase. Data are based on the intention to treat. Results: At the end of Phase 1, 90% of patients in the group receiving RHP first (group A), showed a reduction in pain, as compared to 36% in the group B initially given placebo (p 0.029). In line with this observation, stiffness and the general feeling of discomfort from the disease declined during RHP treatment (p 0.032). In group A, symptom reduction was still indicated by the study subjects 3 weeks after the switch to placebo. The consumption of rescue medication such as paracetamol, codeine and tramadol also declined significantly in group A when compared to group B (p 0.013). Conclusion: The present data suggest that administration of RHP, containing seeds and shells can reduce symptoms of osteoarthritis of the hand and consumption of rescue medication.

High-throughput screening of mouse gene knockouts identifies established and novel skeletal phenotypes

Screening gene function in vivo is a powerful approach to discover novel drug targets. We present high-throughput screening （HTS） data for 3 762 distinct global gene knockout （KO） mouse lines with viable adult homozygous mice generated using either gene-trap or homologous recombination technologies. Bone mass was determined from DEXA scans of male and female mice at 14 weeks of age and by microCT analyses of bones from male mice at 16 weeks of age. Wild-type （WT） cagemates/littermates were examined for each gene KO. Lethality was observed in an additional 850 KO lines. Since primary HTS are susceptible to false positive findings, additional cohorts of mice from KO lines with intriguing HTS bone data were examined. Aging, ovariectomy, histomorphometry and bone strength studies were performed and possible non-skeletal phenotypes were explored. Together, these screens identified multiple genes affecting bone mass： 23 previously reported genes （Calcr, Cebpb, Crtap, Dcstamp, Dkkl, Duoxa2, Enppl, Fgf23, Kissl/Kisslr, Kl （Klotho）, Lrp5, Mstn, Neol, Npr2, Ostml, Postn, Sfrp4, S1c30a5, Sic39a13, Sost, Sumf1, Src, Wnt10b）, five novel genes extensively characterized （Cldn18, Fam20c, Lrrkl, Sgpll, Wnt16）, five novel genes with preliminary characterization （Agpat2, RassfS, Slc10a7, Stc26a7, Slc30a10） and three novel undisclosed genes coding for potential osteoporosis drug targets.
