Timing of hepatectomy in resectable synchronous colorectal liver metastases (SCRLM): Simultaneous or delayed?
Conclusions:Simultaneous resection is as efficient as delayed procedure for the long‐term survival. There are evidences implied that in SCRLM patients simultaneous resection is an acceptable and safe option with the carefully good selected conditions.Due to inherent limitations of the present study, future randomized controlled trials are eagerly awaited to confirm this conclusion.

MDM2 SNP309 promoter polymorphism and p53 mutations in urinary bladder carcinoma stage T1
Conclusions: MDM2 SNP309 promoter polymorphism and mutations in p53 were not associated with worse prognosis in this cohort of patients with primary stage T1 urinary bladder carcinoma. However, patients with abnormal p16 expression and a mutated p53 gene had a higher rate of and a shorter time to progression, and p53 gene mutation was associated with an abnormal immunohistochemistry for p53 at a cut-off of 50%.

Assessment of sperm hyperactivated motility and acrosome reaction can discriminate the use of spermatozoa for conventional in vitro fertilisation or intracytoplasmic sperm injection: Preliminary results
Summary Basic semen analysis is insufficient for determining the fertility potential. The aim of this study was to determine if hyperactivated motility (HAM) and acrosome reaction (AR) can be useful tests for evaluating semen quality during male infertility evaluations and to help the clinician decide whether regular insemination or intracytoplasmic sperm injection (ICSI) is preferable during in vitro fertilisation. A prospective study was conducted. Patients with normal sperm according to World Health Organization guidelines who underwent IVF treatment and planned regular insemination were asked to participate. A portion...

Improved MRI R2* relaxometry of iron‐loaded liver with noise correction
In this study, two noise‐corrected models were proposed for the liver R2* quantification: fitting the signal to the first moment and fitting the squared signal to the second moment in the presence of the noncentral chi noise. These two models were compared with the widely implemented offset and truncation models on both simulation and in vivo data. The results demonstrated that the “slow decay component” of the liver R2* was mainly caused by the noise. The offset model considerably overestimated R2* values by incorrectly adding a constant to account for the slow decay component. The truncation model generally produce...

First case of spontaneous myospherulosis of the liver
Introduction Myospherulosis is a rare interaction of extravasated erythrocytes and lipids, resulting in the degeneration of erythrocytes, which are subsequently enclosed by a lipid membrane. Thus, histologically typical, saccular parent bodies containing variable numbers of approximately 6 µm spherules are formed.1 The lesions are usually small (few millimetres to few centimeters) and do not cause any symptoms except swelling at the involved site. Differential diagnoses include carcinomas, metastases, osteofibrosis or echinococcosis due to alikeness in radiographic imaging and morphology. In addition, myospherul...

Comparison of survival of patients with metastases from known versus unknown primaries: survival in metastatic cancer
Conclusions: Patients with CUP have poorer survival than patients with known primaries, except those with brain and respiratory system metastases. Of CUP sites, liver metastases have the worst prognosis. Survival in CUP was comparable to that in metastatic lung cancer. The aggressive behavior of CUP may be due to initial immunosuppression and immunoediting which may allow accumulation of mutations. Upon escape from the suppressed state an unstoppable tumor spread ensues. These novel data on the epidemiology of the metastatic process at the population level demonstrated large survival differences in organ defined metastases...

Mesenchymal stem cells contribute to endogenous FVIII:c production
Abstract Besides the liver, it has been difficult to identify which organ(s) and/or cellular component(s) contribute significantly to the production of human FVIII:c (FVIII). Thus far, only endothelial cells have been shown to constitute a robust extrahepatic source of FVIII, possibly explaining both the diverse presence of FVIII mRNA in the body, and the observed increase in FVIII levels during liver failure. Here, we investigate whether human mesenchymal stem cells (MSC), ubiquitously present in different organs, could also contribute to FVIII production. MSC isolated from human lung, liver, brain, and bone marrow expres...

Molecular Diagnosis of T Cell‐Mediated Rejection in Human Kidney Transplant Biopsies
This study developed a molecular test for T cell‐mediated rejection. We used microarray results from 403 kidney transplant biopsies to derive a classifier assigning T cell‐mediated rejection scores to all biopsies, and compared these with histologic assessments. The score correlated with histologic lesions of T cell‐mediated rejection (infiltrate, tubulitis). The accuracy of the classifier for the histology diagnoses was 89%. Very high and low molecular scores corresponded with unanimity among three pathologists on the presence or absence of T cell‐mediated rejection, respectively. The molecular score had low sensi...

Kidney Transplants With Progressing Chronic Diseases Express High Levels of Acute Kidney Injury Transcripts
This study investigated the significance of this signal in transplants with other conditions, including rejection and recurrent disease. The injury signal was elevated in biopsies in many different conditions, including T cell‐mediated rejection and potentially progressive diseases such as antibody‐mediated rejection and glomerulonephritis. A high injury signal correlated with poor function and with inflammation in areas of fibrosis, but not with fibrosis without inflammation. In multivariate survival analysis, the injury signal in late kidney transplant biopsies strongly predicted future graft loss, similar to a publi...

Galectin‐1 Prolongs Survival of Mouse Liver Allografts From Flt3L‐Pretreated Donors
This study was to investigate the role of galectin‐1 in spontaneous tolerance of liver allografts in mice, and to evaluate the therapeutic effects of galectin‐1 on liver allograft rejection induced by donor Flt3L pretreatment. Blockade of the galectin‐1 pathway via neutralizing antigalectin‐1 mAb did not affect survival of the liver allografts from B6 donors into C3H recipients. Administration of rGal‐1 significantly prolonged survival of liver allografts from Flt3L‐pretreated donors and ameliorated Flt3L‐triggered liver allograft rejection. This effect was associated with increased apoptosis of T cells in bo...

Contraction of the anterior prostate is required for the initiation of micturition
Conclusions Our functional and biometric in vitro analyses of prostate tissue showed sufficient contractile strength of the ventral prostate to induce a shortening of the organ as seen on rtMRI. There was significant higher contractile strength in the ventral prostate than in the dorsal prostate or the proximal urethra. The consistency of in vivo and in vitro results underlines the significance of the ventral prostate for the initiation of normal micturition.

MicroRNA-122-dependent and -independent replication of Hepatitis C Virus in Hep3B human hepatoma cells.
Abstract The study of Hepatitis C Virus (HCV) has benefitted from the use of the Huh7 cell culture system, but until recently there were no other widely used alternatives to this cell line. Here we render another human hepatoma cell line, Hep3B, permissive to the complete virus life cycle by supplementation with the liver-specific microRNA miR-122, known to aid HCV RNA accumulation. When supplemented, Hep3B cells produce J6/JFH-1 virus titres indistinguishable from those produced by Huh7.5 cells. Interestingly, we were able to detect and characterize miR-122-independent replication of di-cistronic replicons in Hep3...

Dog nectin-4 is an epithelial cell receptor for canine distemper virus that facilitates virus entry and syncytia formation.
Abstract Canine distemper virus (CDV) was shown to use dog nectin-4 as a receptor to gain entry into epithelial cells. RNA from dog placenta or MDCK kidney cells was isolated and cDNAs were prepared. Two splice variants of dog nectin-4 were identified. A deletion of 25 amino acids was found in the cytoplasmic domain of dog nectin-4 from MDCK cells, corresponding to a splice variant that is also seen in murine nectin-4, and did not affect its role as a receptor. Both dog nectin-4 and human nectin-4 could function as an entry factor for CDV containing an EGFP reporter gene. Inhibition of dog nectin-4 expression by RN...

Prognostic Significance of Patterns of Seminal Vesicle Invasion of Prostate Cancer

There is no evidence that other histopathological features of SVI need to be reported.Seminal vesicle invasion (SVI) of prostatic carcinoma was defined by the 2009 International Society of Urological Pathology (ISUP) consensus conference on Handling and Staging of Radical Prostatectomy Specimens as cancer invading the muscular wall of the extraprostatic part of the seminal vesicle (SV) 1. SVI is seen in 3.1% 2 – 9.2% 3 of radical prostatectomy (RP) spe...

Identification of human epididymis protein-4 as a fibroblast-derived mediator of fibrosis
Nature Medicine 19, 227 (2013). doi:10.1038/nm.2989 Authors: Valerie S LeBleu, Yingqi Teng, Joyce T O'Connell, David Charytan, Gerhard A Müller, Claudia A Müller, Hikaru Sugimoto & Raghu Kalluri The functional contribution of myofibroblasts in fibrosis is not well understood. Using a new genetic mouse model to track and isolate myofibroblasts, we performed gene expression profiling followed by biological validation to identify HE4 (encoding human epididymis protein 4, also known as WAP 4-disulfide core domain-2 or Wfdc2) as the most upregulated gene in fibrosis-associated myofibroblasts. The HE4 gene ...

[Long-term effects of osteopathic treatment of chronic prostatitis with chronic pelvic pain syndrome : A 5-year follow-up of a randomized controlled trial and considerations on the pathophysiological context.]
CONCLUSIONS: Due to the sustainability of osteopathic treatment and the low amount of time involved, osteopathy should be taken seriously as a treatment for patients with CP/CPPS. Furthermore, due to the osteopathic treatment the patients learnt to alleviate or even eliminate their own symptoms in treating themselves. In order to help many other affected persons out of their dilemma it would be desirable if more urologists and internists would become acquainted with osteopathy in order to be able to offer this to patients at an early stage. Further studies with larger numbers of patients should be carried out to con...

Antitumor and antiangiogenic active dendrimer/5-fluorouracil conjugates.
Abstract Antitumor and antiangiogenic active dendritic compounds conjugated with 5-fluorouracil (5-FU) were synthesized and characterized. First, the core structure based on ascorbic acid and dicarboxylic acid was synthesized, amidated with ethylenediamine. For the synthesis of higher generated dendrimer, it was reacted further with methyl acrylate to increase molecular weight through Michael addition reaction, followed by the continuous repeating amidation reaction, finally, used to synthesize covalently bound dendrimer/5-FU conjugates. The in vitro cytotoxicities of the conjugates was evaluated with mouse mammary...
