Transverse myocutaneous gracilis flap reconstruction is feasible after pelvic exenteration: 12-year surgical and oncological results.

Introduction: Pelvic exenteration (PE) is the only curative treatment for certain locally advanced intrapelvic malignancies. PE has high morbidity, and optimal reconstruction of the pelvic floor remains undetermined.

Materials And Methods: A retrospective chart review was performed at a tertiary university center to assess the surgical and oncological outcomes of 39 PE procedures over a 12-year period.

Reconstruction of the pelvic floor and the vagina after total pelvic exenteration using the transverse musculocutaneous gracilis flap.

Background: Total pelvic exenteration (TPE) is a rare operation in which the pelvic contents are removed entirely. Several options for pelvic floor and vaginal reconstruction have been described including transverse rectus abdominis musculocutaneous (TRAM) or deep inferior epigastric perforator (DIEP) flaps. The transverse musculocutaneous gracilis (TMG) flap has been introduced for breast reconstruction as a free flap.

Role of mitochondria in parvovirus pathology.

Proper functioning of the mitochondria is crucial for the survival of the cell. Viruses are able to interfere with mitochondrial functions as they infect the host cell. Parvoviruses are known to induce apoptosis in infected cells, but the role of the mitochondria in parvovirus induced cytopathy is only partially known.

Endoglin, VEGF, and its receptors in predicting metastases in endometrial carcinoma.

Preoperative evaluation of the risk for metastases in endometrial carcinoma is challenging. The growth of new vessels, angiogenesis, is important for tumor growth and purported to be involved in the metastatic process. The aim of this study was to evaluate the significance of preoperative serum levels and immunohistochemical expression of angiogenic markers in predicting a metastasized disease.

Reconstruction of the vulva with sensate gluteal fold flaps.

Background And Aims: Soft-tissue reconstruction of the vulva following resection of malignancies is challenging. The function of perineal organs should be preserved and the reconstructed area should maintain an acceptable cosmetic appearance. Reconstruction with local flaps is usually sufficient in the primary phase after a radical vulvectomy.

Predictive value of serum human epididymis protein 4 and cancer antigen 125 concentrations in endometrial carcinoma.

Objective: The purpose of this study was to evaluate the performance of preoperative serum levels of human epididymis protein 4 (HE4) and cancer antigen 125 (CA125) in the prediction of the presence of metastases in endometrial carcinoma.

Study Design: Preoperative sera were collected from 98 women with a diagnosis of endometrial carcinoma. The concentrations of HE4 and CA125 were assessed by enzyme-linked immunosorbent assay and correlated with the results of the final histopathologic report.

High-fat feeding induces angiogenesis in skeletal muscle and activates angiogenic pathways in capillaries.

High-fat diet (HFD) increases fatty acid oxidation in skeletal muscles. We hypothesized that this leads to increased oxygen demand and thus to increased capillarization. We determined the effects of high-fat diet on capillarization and angiogenic factors in skeletal muscles of mice that were either active or sedentary.

[Update on current care guidelines: ovarian cancer].

Ovarian cancer is the most lethal gynaecological cancer. It appears that seemingly ovarian or primary peritoneal carcinomas, in fact, originate from fimbriae. BRCA1/2 mutation carriers are recommended for the removal of ovaries and fimbriae, to reduce the risk of cancer.

The putative metal coordination motif in the endonuclease domain of human Parvovirus B19 NS1 is critical for NS1 induced S phase arrest and DNA damage.

The non-structural proteins (NS) of the parvovirus family are highly conserved multi-functional molecules that have been extensively characterized and shown to be integral to viral replication. Along with NTP-dependent helicase activity, these proteins carry within their sequences domains that allow them to bind DNA and act as nucleases in order to resolve the concatameric intermediates developed during viral replication. The parvovirus B19 NS1 protein contains sequence domains highly similar to those previously implicated in the above-described functions of NS proteins from adeno-associated virus (AAV), minute virus of mice (MVM) and other non-human parvoviruses.

Preoperative assessment of endometrial carcinoma by three-dimensional power Doppler angiography.

Objective: Preoperative evaluation of the depth of myometrial invasion in endometrial carcinoma is challenging. The objective of this study was to evaluate the usefulness of three-dimensional power Doppler angiography (3D-PDA) in this setting.

Methods: Sonographic and histological data on 100 consecutive cases of endometrial carcinoma were analyzed.

[Update on current care guidelines. Diagnosis, treatment and follow-up of cytological changes in the cervix, vagina and vulva].

Approximately 150 cervical cancer cases are diagnosed in Finland annually. Both incidence and mortality have decreased by 80% since organised screening began. Recently, screening based on primary HPV-testing with Pap-smear triage has been shown to be more sensitive and more specific among women over 35 years old in randomised studies and thus may be implemented in routine.

Mechanisms of cell death in canine parvovirus-infected cells provide intuitive insights to developing nanotools for medicine.

Viruses have great potential as nanotools in medicine for gene transfer, targeted gene delivery, and oncolytic cancer virotherapy. Here we have studied cell death mechanisms of canine parvovirus (CPV) to increase the knowledge on the CPV life cycle in order to facilitate the development of better parvovirus vectors. Morphological studies of CPV-infected Norden laboratory feline kidney (NLFK) cells and canine fibroma cells (A72) displayed characteristic apoptotic events.

Gene expression centroids that link with low intrinsic aerobic exercise capacity and complex disease risk.

A strong link exists between low aerobic exercise capacity and complex metabolic diseases. To probe this linkage, we utilized rat models of low and high intrinsic aerobic endurance running capacity that differ also in the risk for metabolic syndrome. We investigated in skeletal muscle gene-phenotype relationships that connect aerobic endurance capacity with metabolic disease risk factors.

Parvovirus B19 genotype specific amino acid substitution in NS1 reduces the protein's cytotoxicity in culture.

A clinical association between idiopathic liver disease and parvovirus B19 infection has been observed. Fulminant liver failure, not associated with other liver-tropic viruses, has been attributed to B19 in numerous reports, suggesting a possible role for B19 components in the extensive hepatocyte cytotoxicity observed in this condition. A recent report by Abe and colleagues (Int J Med Sci.

Phase coexistence in a triolein-phosphatidylcholine system. Implications for lysosomal membrane properties.

The effects of tri- and monoglycerides on phospholipid (POPC) membranes were studied using spectroscopical methods. Triolein was found to form two types of POPC-rich membranes, both with POPC or as a three-component system with monopalmitin. These two membrane types were determined as co-existing phases based on their spontaneous and stable separation and named heavy and light phase according to their sedimentation behaviour.

Desipramine induces disorder in cholesterol-rich membranes: implications for viral trafficking.

In this study, the effect of desipramine (DMI) on phospholipid bilayers and parvoviral entry was elucidated. In atomistic molecular dynamics simulations, DMI was found to introduce disorder in cholesterol-rich phospholipid bilayers. This was manifested by a decrease in the deuterium order parameter S(CD) as well as an increase in the membrane area.

Early succession of bacterial biofilms in paper machines.

Formation of biofilms causes severe problems in paper machines, and hence financial costs. It would be preferable to prevent attachment of the primary-colonizing bacteria than to control the growth of secondary communities, which are sheltered by exopolysaccharide slime layers. We have therefore investigated the early succession of paper-machine biofilms by incubating stainless-steel test coupons in the process water-flow lines in two paper machines operating in slightly alkaline conditions in temperatures (45 and 49 degrees C) supporting thermophilic microbes.

Parvovirus capsid disorders cholesterol-rich membranes.

In this study canine parvovirus, CPV, was found to induce disorder in DPPC:cholesterol membranes in acidic conditions. This acidicity-induced fluidizing effect is suggested to originate from the N-terminus of the viral capsid protein VP1. In accordance with the model membrane studies, a fluidizing effect was seen also in the endosomal membranes during CPV infection implying an important functional role of the fluidization in the endocytic entry of the virus.

Method and apparatus using selected superparamagnetic labels for rapid quantification of immunochromatographic tests.

A rapid method and instrumentation for quantification of immunochromatographic tests (ICT) are described. The principle and performance of the method was demonstrated by measuring the levels of human chorionic gonadotropin (hCG) present in urine. The test format was a sandwich assay using two distinct monoclonal antibodies directed against hCG.

Late steps of parvoviral infection induce changes in cell morphology.

Previously, virus-induced non-filopodial extensions have not been encountered in connection with viral infections. Here, we report emergence of long extensions protruding from Norden laboratory feline kidney (NLFK) and A72 (canine fibroma) cells infected with canine parvovirus for 72 h. These extensions significantly differ in length and number from those appearing in control cells.

Sphingomyelin induces structural alteration in canine parvovirus capsid.

One of the essential steps in canine parvovirus (CPV) infection, the release from endosomal vesicles, is dominated by interactions between the virus capsid and the endosomal membranes. In this study, the effect of sphingomyelin and phosphatidyl serine on canine parvovirus capsid and on the phospholipase A(2) (PLA(2)) activity of CPV VP1 unique N-terminus was analyzed. Accordingly, a significant (P< or =0.

Ultrasonographic-guided pervaginal cul-de-sac cytology in the follow-up of ovarian carcinoma.

Unlabelled: The aim of this study was to compare, prospectively, traditional pervaginal cul-de-sac aspiration cytology with an ultrasonographic-guided aspirate in the detection of residual or recurrent ovarian carcinoma.

Patients And Methods: Fifty-one patients with ovarian carcinoma were monitored during chemotherapy (21 patients) or follow-up (30 patients) after first-line treatment. All patients underwent both traditional blind pervaginal cul-de-sac aspiration cytology and an ultrasonographic-guided pervaginal aspirate.

Ultrasonographic assessment of weight of the myomatous uterus: a pilot study using a new combined geometrical formula.

Objective: To evaluate the accuracy of a formula combining the prolate ellipsoid (uterine corpus) and cylinder (uterine cervix) formulas in estimating the preoperative weight of the total uterus using a transvaginal ultrasound probe to obtain the uterine dimensions for the formulas.

Study Design: Three dimensions of the uterine corpus (length, width and anteroposterior diameter) and cervical length and cervical anteroposterior diameter were preoperatively determined using a transvaginal ultrasound probe in 12 women with symptomatic leiomyomas scheduled to undergo hysterectomy. In two patients whose uteruses were the largest, part of the measurements had to be taken with a transabdominal ultrasound.

Truncated forms of viral VP2 proteins fused to EGFP assemble into fluorescent parvovirus-like particles.

Fluorescence correlation spectroscopy (FCS) monitors random movements of fluorescent molecules in solution, giving information about the number and the size of for example nano-particles. The canine parvovirus VP2 structural protein as well as N-terminal deletion mutants of VP2 (-14, -23, and -40 amino acids) were fused to the C-terminus of the enhanced green fluorescent protein (EGFP). The proteins were produced in insect cells, purified, and analyzed by western blotting, confocal and electron microscopy as well as FCS.
