Cancer - An Insurgency of Clones

Oncological therapy resembles a military force that eliminates the central power of a country (dominant clone of a cancer) to create a vacuum where insurgents (subclones) thrive and instigate rebellion (relapse). We suggest that military counterinsurgency doctrine can inspire a discussion of cancer that uniquely embraces both cancer cell evolution and tumour microenvironment.

Outcome of men with relapse after adjuvant carboplatin for clinical stage i seminoma

Purpose Adjuvant carboplatin is one of three management strategies that may follow inguinal orchiectomy in clinical stage I seminoma. However, little is known about the outcome of patients who experience a relapse after such treatment. Patients and Methods Data from 185 patients who relapsed after adjuvant carboplatin between January 1987 and August 2013 at 31 centers/groups from 20 countries were

Intra-and inter-observer reliability of nailfold videocapillaroscopy - A possible outcome measure for systemic sclerosis-related microangiopathy

OBJECTIVES: Our aim was to assess the reliability of nailfold capillary assessment in terms of image evaluability, image severity grade ('normal', 'early', 'active', 'late'), capillary density, capillary (apex) width, and presence of giant capillaries, and also to gain further insight into differences in these parameters between patients with systemic sclerosis (SSc), patients with primary Raynaud

Acute infection with the intestinal parasite Trichuris muris has long-term consequences on mucosal mast cell homeostasis and epithelial integrity

A hallmark of parasite infection is the accumulation of innate immune cells, notably granulocytes and mast cells, at the site of infection. While this is typically viewed as a transient response, with the tissue returning to steady state once the infection is cleared, we found that mast cells accumulated in the large-intestinal epithelium following infection with the nematode Trichuris muris and p

Effects of oil and oil burn residues on seabird feathers

It is well known, that in case of oil spill, seabirds are among the groups of animals most vulnerable. Even small amounts of oil can have lethal effects by destroying the waterproofing of their plumage, leading to loss of insulation and buoyancy. In the Arctic these impacts are intensified. To protect seabirds, a rapid removal of oil is crucial and in situ burning could be an efficient method. In

Cognitive abnormalities and cerebral perfusion defects in a community-dwelling cohort of elderly men with MMSE within the normal range

Objectives: Mini Mental State Examination’s (MMSE’s) sensitivity in its upper level is questioned, hence we investigated cognitive abnormalities and defects in regional cerebral blood flow (rCBF) in elderly with MMSE scores ≥24. Methods: One hundred and four men at age 81 with MMSE scores ≥24 (mean 28.4 ± 1.7), no dementia or stroke, were examined with neuropsychological test battery, and their rC

Migration and wintering of a declining seabird, the thick-billed murre Uria lomvia, on an ocean basin scale : Conservation implications

Pelagic seabirds are exposed to an array of potential threats during the non-breeding period, and effective management of these threats on a large scale requires knowledge of which populations winter where. Thick-billed murres (Uria lomvia) are emblematic of this conservation challenge, since they breed widely in the circumpolar Arctic, with many declining populations in the Atlantic. Threats faci

Arthroscopically assisted anterior cruciate ligament reconstruction with bone-patellar tendon-bone autograft without wound drainage : Short- to middle-term outcome

Introduction: Several studies have suggested that anterior cruciate ligament reconstruction (ACLR) without wound drainage has no impact on long-term follow-up. Aim: To investigate a prospective patient series as measured by the patient-administered disease-specifc questionnaire Knee injury and Osteoarthritis Outcome Score (KOOS). Material and methods: The study included 101 consecutive patients (7

Observations on normal EEG activity in different brain regions of the unrestrained swine

This methodological and electrophysiological study was undertaken with the aim of obtaining possibilities for evaluating objectively the ethical value of using high concentration CO2 inhalation as pre-slaughter anaesthesia for swine. A technique for implantation of recording electrodes into the porcine neocortex and limbic system is described, as are results of EEG recording from these brain regio

The evolution of an enterprise system implementation methodology by adaptation through reflexivity

In spite of an Enterprise Systems Implementation Methodology's (ESIM's) potential and significance for Enterprise Systems implementation, little attention has been paid to its evolution in ES literature. Moreover, current studies reveal contradictory findings and provide a fragmented understanding. The purpose of this paper is to provide a framework underpinned by a morphogenetic approach for expl

Transient neocortical, hippocampal and amygdaloid EEG silence induced by one minute inhalation of high concentration CO2 in swine

The study is part of a series of investigations performed with the ultimate goal of obtaining an objective evaluation of the ethical aspects and the narcotic efficiency of CO2 inhalation used as pre-slaughter anaesthesia for swine. Six Yorkshire swine were exposed twice to 80% CO2 for I min during simultaneous recording of the EEGs from the frontal neocortex, the dorsal hippocampus, and the amygda

The 2016 update of the International Study Group (ISGPS) definition and grading of postoperative pancreatic fistula : 11 Years After

Background: In 2005, the International Study Group of Pancreatic Fistula developed a definition and grading of postoperative pancreatic fistula that has been accepted universally. Eleven years later, because postoperative pancreatic fistula remains one of the most relevant and harmful complications of pancreatic operation, the International Study Group of Pancreatic Fistula classification has beco

Conodont faunal dynamics across the middle and upper ordovician boundary in the Yichang area, western Hubei province, South China

A total of 6094 conodont specimens, assigned to 18 genera and 27 species, have been recovered from the uppermost Kuniutan and Miaopo formations, spanning the latest Darriwilian - early Sandbian in age, at the Jieling section, Yichang, Hubei Province. Three conodont zones have been recognized, i.e., in ascending order, the Pygodus serra Zone, the Pygodus anserinus - Yangtzeplacognathus jianyeensis

Bimetallic nickel and palladium complexes for catalytic applications

South Africa is a mineral-rich country and one area in which minerals can be very important is catalysis. Over an extended period of time, homogeneous catalysis has grown to become very useful, particularly in the chemical and pharmaceutical industries. The organometallic compounds required in the catalysis industry have advanced from metallocenes to an alternative in the form of α-diimines. Most
