Treatment of tumors of the pancreatic head with suspected but unproved malignancy: is a nihilistic approach justified?
1999
The aim of the present prospective observational study was to evaluate the accuracy of preoperative imaging studies and the outcome of patients after pancreaticoduodenectomy for suspected but unproved malignancy. Pancreaticoduodenectomy was performed in 186 patients with a suspected but histologically unproved malignancy of the pancreatic head: 86 with a ductal pancreatic carcinoma, 56 with a periampullary tumor, 18 with a cystadenocarcinoma, 13 with a rare malignant tumor or a metastasis, and 13 with a benign tumor. An accurate differentiation between a ductal pancreatic carcinoma and a nonductal tumor or a benign tumor was neither possible with tumor marker CA 19-9 nor with diagnostic ima…
Promyelocytic leukemia (PML) gene expression is a prognostic factor in ampullary cancer patients
2008
Background: Promyelocytic leukemia (PML) tumor suppressor gene plays a key role in acute PML pathogenesis but its involvement in pathogenesis and prognosis of solid cancers has not been defined yet. Patients and methods: In all, 62 ampullary adenocarcinoma patients who underwent curative surgery between 1996 and 2005 were included. Expression analysis of PML was carried out by immunohistochemical staining and correlated with disease-free survival (DFS) and overall survival (OS). Results: In 24 tumor specimens (38.7%), PML was classified as absent, in 16 (25.8%) as focally expressed and in 22 (35.5%) as diffusely expressed. By univariate analysis, DFS was significantly influenced by patholog…
Muscle loading and activation of the shoulder joint during humeral external rotation by pulley and variable resistance.
2010
The aim of the study was to evaluate differences in the loading of glenohumeral joint muscles between a cable pulley machine (CP) and variable resistance machine (VR) during axial humeral external rotation.Eleven healthy male subjects took part in the study. Intramuscular electromyography from five muscles of the shoulder (medial deltoid, supraspinatus, infraspinatus and upper part of the trapezius), torque and power output was measured at different rotation angles and with different loads (10%, 50% and 100% of 1RM). Also the compressive and shear force in the glenohumeral joint was analyzed at the horizontal level at angles of rotation. External rotation was performed with a self-selected …
A method for monitoring intensity during aquatic resistance exercises.
2008
The aims of this study were (i) to check whether monitoring of both the rhythm of execution and the perceived effort is a valid tool for reproducing the same intensity of effort in different sets of the same aquatic resistance exercise (ARE) and (ii) to assess whether this method allows the ARE to be put at the same intensity level as its equivalent carried out on dry land. Four healthy trained young men performed horizontal shoulder abduction and adduction (HSAb/Ad) movements in water and on dry land. Muscle activation was recorded using surface electromyography of 1 stabilizer and several agonist muscles. Before the final tests, the ARE movement cadence was established individually follow…
Perineural Invasion is a Strong Prognostic Moderator in Ampulla of Vater Carcinoma
2018
Objective Ampulla of Vater carcinoma (AVC) has a broad spectrum of different prognoses. As such, new moderators of survival are urgently needed. We aimed at clarifying the prognostic role of perineural invasion in AVC. Methods Using PubMed and SCOPUS databases, we conducted the first systematic review and meta-analysis on this topic. Results Analyzing 29 articles for a total of 2379 patients, we found that the presence of perineural invasion increased the risk of all-cause mortality more than 2 times (relative risk [RR], 2.07; 95% confidence interval [CI], 1.78-2.42 [P < 0.0001]; hazard ratio [HR], 2.72; 95% CI, 1.86-3.97 [P < 0.0001]), of cancer-specific mortality more than 6 times (…

Prognostisch relevante Faktoren beim Carcinom der Papilla Vateri
1989
In order to evaluate the relevant factors for prognosis for patients with cancer of Vater's papilla our own patient material between 1. 1. 1978 and 31. 12. 1987 was studied retrospectively. The influence of age, sex, duration of anamnesis, tumor size, tumor morphology and tumor stage on the prognosis were analyzed in 32 patients with cancer of Vater's papilla. The 5 year survival rate after Whipple procedure was 56.1%. Statistically significant factors for prognosis were tumor size, lymph node metastases and tumor stage.
Pullneyocoris dentatus gen. et sp. nov. (Hemiptera: Pentatomoidea: Cydnidae), the third representative of the subfamily Amnestinae from mid-Cretaceou…
2020
Abstract A new genus and species of burrower bug, Pullneyocoris dentatus gen. et sp. nov. (Hemiptera: Cydnidae: Amnestinae), is described from amber of northern Myanmar. It is the third representative of this family known from Burmese amber, and besides its autapomorphies, it presents a mixture of characters relevant to the extant Parachilocoris Horvath, 1919 and Pullneya Horvath, 1919. A comparison of this new genus to the two genera already described from the burmite, i.e. Chilamnestocoris Lis J.A., Lis. B. & Heiss, 2018, and Punctacorona Wang, Du, Yao & Ren, 2019 is also provided.
Untersuchungen zur Sterinsynthese des Ascomyceten Aureobasidium (Dematium) pullulans / Studies of the Sterolsynthesis in the Fungus Aureobasidium (De…
1985
Abstract Isolation and identification of sterols from culture extracts of the fungus Aureobasidium (Dematium) pullulans yielded metabolites with key function in sterol synthesis. By proof of squalene, lanosterol/dihydrolanosterol, desmosterol, ergosterol, cholesterol, stigmasterol and β-sitosterol it was possible to work out a general synthesis-scheme for the building-up of sundry sterols in Ascomycetes.
