High-frequency ultrasonography has become an important diagnostic tool in dermatovenerology. It is used for assessment of the cutaneous layers in diverse benign and malignant skin lesions and diseases. Herein we present the practical value of preoperative measurement of cutaneous melanoma thickness, the explanation of the possible reasons for different sonographic and histologic Breslow thickness, and the practical importance of high-frequency 20 MHz ultrasonography in preoperative measurements of cutaneous melanoma thickness...

Changes in QRS duration and pattern are regarded to reflect severe ischemia in acute coronary syndromes (ACS), and ventricular conduction blocks (VCBs) are recognized high-risk markers in both ACS and acute heart failure. Our aim was to evaluate the prevalence, temporal evolution, association with clinical and angiographic parameters, and impact on mortality of VCBs in ACS-related cardiogenic shock (CS). Data of 199 patients with ACS-related CS from a prospective multinational cohort were evaluated with electrocardiogram data from baseline and day 3...

OBJECTIVE Blood vessel tortuosity may play an important role in the development of vessel abnormalities such as aneurysms. Currently, however, there are no studies analyzing the impact of brain blood vessel tortuosity on the risk of aneurysm formation. Therefore, the authors performed a computer-aided analysis of middle cerebral artery (MCA) tortuosity, especially among patients diagnosed with MCA aneurysms. METHODS Anatomy of the MCAs of 54 patients with unruptured MCA aneurysms was retrospectively analyzed, as was that of 54 sex-, age-, and vessel side-matched control patients without MCA aneurysms...

Marek's disease virus (MDV) is a herpesvirus that induces lymphoma and a variety of non-neoplastic syndromes in chickens. Furthermore, very virulent plus (vv+) MDVs induce a form of immunosuppression (late-MDV-IS) that might involve both neoplastic and non-neoplastic mechanisms. The objective of this study was to evaluate whether the attenuation of MDV-induced tumours and late-MDV-IS occurs simultaneously or can be dissociated. The immunosuppressive ability of three viruses derived from vv+ MDV strain 686 (wild-type 686, the somewhat attenuated molecular clone 686-BAC, and the nononcogenic molecular clone lacking the two copies of the oncogene meq 686-BACΔMEQ) was evaluated...

A disease associated with immunoglobulin IgG4 is a rare unit with very variable symptoms. We describe the course and treatment of the disease in a patient who presented with multiple lymphadenopathy and infiltrates in the area of the retroperitoneum and pelvis and signs of chronic sclerosing pancreatitis. The disease was clinically manifested by a significant loss of weight, but also by a loss of perception of taste and smell. The diagnosis was made based on a high amount of IgG4 expressing plasma cells in the sampled tissue and an increased concentration of immunoglobulins of type IgG and mainly subclass IG4...

Introduction: Psoriasis is a common, chronic inflammatory disease characterised by typical scaly skin lesions. The role of matrix metalloproteinases (MMPs) and their tissue inhibitors (TIMPs) in the pathogenesis and development of this condition have been repeatedly emphasised in available literature. Aim: ROC analysis of selected MMPs (MMP-2, MMP-3, MMP-9, MMP-12, TIMP-2) and TIMPs (TIMP-2, TIMP-3) in psoriasis patients. The area under the ROC curve (AUC) indicates the clinical usefulness of a biomarker and its diagnostic power...

This article reports nine cases of neurological disease in brown layer pullets that occur in various European countries between 2015 and 2018. In all cases, the onset of neurological clinical signs was at 4-8 weeks of age and they lasted up to 22 weeks of age. Enlargement of peripheral nerves was the main lesion observed in all cases. Histopathological evaluation of nerves revealed edema with moderate to severe infiltration of plasma cells. Marek's disease (MD) was ruled out by real time PCR as none of the evaluated tissues had high load of oncogenic MD virus (MDV) DNA, characteristics of MD...

Analysis of induced sputum supernatant is a minimally invasive approach to study the epithelial lining fluid and, thereby, provide insight into normal lung biology and the pathobiology of lung diseases. We present here a novel proteomics approach to sputum analysis developed within the U-BIOPRED (Unbiased BIOmarkers Predictive of REspiratory Disease outcomes) international project. We present practical and analytical techniques to optimise the detection of robust biomarkers in proteomic studies. The normal sputum proteome was derived using data-independent HDMSE applied to 40 healthy non-smoking participants, which provides an essential baseline from which to compare modulation of protein expression in respiratory diseases...

The endocannabinoid system is up-regulated in numerous pathophysiological states such as inflammatory, neurodegenerative, gastrointestinal, metabolic and cardiovascular diseases, pain, and cancer. It has been suggested that this phenomenon primarily serves an autoprotective role in inhibiting disease progression and/or diminishing signs and symptoms. Accordingly, enhancement of endogenous endocannabinoid tone by inhibition of endocannabinoid degradation represents a promising therapeutic approach for the treatment of many diseases...

INTRODUCTION: Olfactory dysfunction has been established as a frequent non-motor symptom in neurodegenerative and movement disorders such as Parkinson's disease, Alzheimer's disease, and hereditary ataxias. To expand knowledge of non-motor symptoms in dystonia, and to test for a potential endophenotype, we examined olfactory function in cervical dystonia (CD). METHODS: In patients with CD, and neurologically healthy controls, olfactory function was examined by "Sniffin' Sticks", a test of nasal chemosensory function based on pen-like odor dispensing devices...

BACKGROUND: The aim was to develop prediction rules that may guide early treatment decisions based on baseline clinical predictors of long-term unfavorable outcome in juvenile idiopathic arthritis (JIA). METHODS: In the Nordic JIA cohort, we assessed baseline disease characteristics as predictors of the following outcomes 8 years after disease onset. Non-achievement of remission off medication according to the preliminary Wallace criteria, functional disability assessed by Childhood Health Assessment Questionnaire (CHAQ) and Physical Summary Score (PhS) of the Child Health Questionnaire, and articular damage assessed by the Juvenile Arthritis Damage Index-Articular (JADI-A)...

The molecular chaperone endoplasmic reticulum protein 29 (ERp29) plays a critical role in protein folding, trafficking, and secretion. Though ubiquitously expressed, ERp29 is upregulated in response to ER stress and is found at higher levels in certain cell types such as secretory epithelial cells and neurons. As an ER resident protein, ERp29 shares many structural and functional similarities with protein disulfide isomerases, but is not regarded as part of this family due to several key differences. The broad expression and myriad roles of ERp29 coupled with its upregulation via the unfolded protein response (UPR) upon ER stress have implicated ERp29 in a range of cellular processes and diseases...

Colorectal cancer (CRC) is one of the most commonly diagnosed cancers and a major cause of cancer mortality worldwide. At late stage of the disease CRC often shows (multiple) metastatic lesions in the peritoneal cavity which cannot be efficiently targeted by systemic chemotherapy. This is one major factor contributing to poor prognosis. Oxaliplatin is one of the most commonly used systemic treatment options for advanced CRC. However, drug resistance - often due to insufficient drug delivery - is still hampering successful treatment...

Numerous genetic alterations predicting prognosis and clinical outcome are revealed recently in chronic lymphocytic leukemia (CLL). Among them the deregulated expression of micro RNAs that can induce tumor growth, or act as tumor suppressors seem to be of great importance. This study aimed to analyze the possible role of chosen micro RNAs as markers of prognosis in patients with CLL. We assessed the expression of miR-21, miR-34a, miR-181a, miR-199a/b and miR-221 in previously separated leukemic cells with the use of qRQ-PCR technique at the moment of diagnosis...
