Cancer is responsible for millions of deaths worldwide, but most base diseases may be cured if detected early. Screening tests may be used to identify early-stage malignant neoplasms. However, the major screening tool for prostate cancer, the prostate-specific antigen test, has unsuitable sensitivity. Since cancer cells may affect the pattern of consumption and excretion of nucleosides, such biomolecules are putative biomarkers that can be used for diagnosis and treatment evaluation. Using a previously validated method for the analysis of nucleosides in blood serum by capillary electrophoresis with UV-vis spectroscopy detection, we investigated 60 samples from healthy individuals and 42 samples from prostate cancer patients...

En-face fat staining is frequently used to visualize atherosclerotic lesions. This method, however, is not suitable to visualize endothelial barrier damage prior to microscopically detectable morphological alterations of the arterial wall such as sub-endothelial lipid deposition. To enable the investigation of early endothelial barrier damage and in particular the initial steps of atherosclerosis, a new method has to fulfill three requirements: (i) easy and fast to perform, (ii) low cost of applicability without requirement for highly sophisticated technical equipment, and (iii) reliable reproducibility of valid results...

The incidence of segmental testicular infarction (STI) is very low. Such a disorder most often affects young men. The most common symptom is sudden testicular pain. We report 6 cases of men diagnosed with STI. Clinical examination, blood test, urine analysis, and ultrasound examination with colour Doppler were performed. Furthermore, tissue sonoelastography or MRI was performed in selected patients. All men underwent surgical exploration. In all but one man, the affected testis was preserved. Although STI is a rare condition, it should be taken into account if testicular pain prior to suspicious ultrasound imaging occurs...

INTRODUCTION: Periodic fever, aphthous stomatitis, pharyngitis and cervical adenitis (PFAPA) syndrome refers to a group of primary immunodeficiencies, namely autoinflammatory diseases. Most pediatricians and otolaryngologists do not suspect PFAPA syndrome when treating recurrent pharyngitis (according to Ukrainian classification - tonsillitis) and stomatitis. Therefore, patients with a given syndrome receive unnecessary treatment (antibiotic therapy or antiviral drugs) and the diagnosis is made late...

A young man presented to accident and emergency with a short history of diarrhoea and vomiting, with no medical history. He deteriorated rapidly during triage and never regained consciousness. He was pronounced dead after hours of attempted resuscitation. He was found to have organisms suggestive of diplococci on his blood film and subsequently had MenY found via PCR testing. This case illustrates a highly unusual presentation of invasive meningococcal disease caused by MenY which is quietly and dangerously increasing in incidence in the UK, particularly in young healthy patients...

BACKGROUND: Point-of-care testing (POCT) is regularly used to assess haemostasis in various clinical settings. The impact of rivaroxaban on those POCT is still elusive. We aimed to study the effects of rivaroxaban on most commonly used POCT assays. METHODS: Blood samples were taken before, 3h, and 24h after administration of 20mg rivaroxaban to 20 healthy volunteers as part of a prospective, multicenter validation study (clinicaltrials.govNCT01710267). Blood samples were analysed with thromboelastometry (ROTEM®), two platelet function assays (INNOVANCE® PFA-200 and Multiplate®), and the CoaguChek® XS...

BACKGROUND: Sepsis is an important cause of morbidity and mortality in neonates and clinicians are typically required to administer empiric antibiotics while waiting for blood culture results. However, prolonged and inappropriate use of antibiotics is associated with various complications and adverse events. Better tools to rapidly rule out bacterial infections are therefore needed. AIMS: We aimed to assess the negative predictive value of PCR coupled with Electrospray Ionization Mass Spectrometry (PCR/ESI-MS) compared to conventional blood cultures in neonatal sepsis...

The potential of molybdenum substances to cause genotoxic effects has been studied previously. However, a review of existing in vitro data, including an assessment of relevance and reliability, has shown that inconsistent results have been observed in the past. To resolve the inconsistencies, new studies were performed with the highly soluble sodium molybdate dihydrate according to OECD test guidelines. In a bacterial reverse mutation assay sodium molybdate dihydrate did not induce reverse mutations in five strains of Salmonella typhimurium...

Jatropha dioica Sessé ex Cerv. is a medicinal plant credited with low cytotoxicity in vitro. Thus, the objective of this work was to evaluate the possible genotoxic and cytotoxic effect in vivo of the J. dioica aqueous extract by means of micronucleus assay in mouse peripheral blood. Four different J. dioica aqueous extract dose-units were evaluated (30, 60, 100, and 300 mg/kg). The extract was administered orally to male Balb-C-strain mice every 24 h during 5 days. Blood samples were taken at 0, 24, 48, 72, 96, and 120 h from the mouse's tail and were performed in duplicate extensions...

BACKGROUND: Patients can react to amoxicillin (AX) and clavulanic acid (CLV) taken in combination because of selective reactions to either drug. However, scant information exists concerning patients who react simultaneously to both compounds. OBJECTIVE: To analyze the mechanisms involved in 4 patients who developed allergic reactions to AX-CLV administration (3 with immediate IgE-mediated reaction and 1 with nonimmediate T-cell-mediated reaction) and who responded specifically to both AX and CLV...

When animals are reared for conservational releases it is paramount to avoid reducing genetic and phenotypic variation over time. This requires an understanding of how diverging behavioural and physiological traits affect performance both in captivity and after release. In Atlantic salmon, emergence time from the spawning gravel has been linked to certain behavioural and physiological characteristics and to the concept of stress coping styles. Early emerging fry has for example been shown to be bolder and more aggressive and to have higher standard metabolic rates compared to late emerging fry...

Our concept of nucleic acid biology has advanced dramatically over the past two decades, with a growing appreciation that cell-free DNA (cfDNA) fragments are present in all body fluids including plasma. In no other field has plasma DNA been as rapidly translated into clinical practice as in noninvasive prenatal testing (NIPT) for fetal chromosome abnormalities. NIPT is a screening test that requires confirmation with diagnostic testing, but other applications of cfDNA provide diagnostic information and do not require invasive testing...

In recent years, various kinds of endocrine-disrupting chemicals (EDCs) have been detected in human blood and urine. Thus, it was important to investigate the combined toxicity effect of EDCs. In the present study, we evaluated the individual and combined developmental toxicities of three classic EDCs: perfluorooctane sulfonate (PFOS), perfluorooctanoic acid (PFOA), and bisphenol A (BPA) by embryonic stem cell test (EST). The similarities and differences between combination of same chemical group as well as different chemical groups were investigated in this research...

Frequent breaks in prolonged sitting are associated beneficially with glycaemic control. However, the contribution of energy expenditure to these relationships has not been well characterised. In this exploratory analysis, data from three laboratory trials that standardised test meals, cohort characteristics (overweight/obese, sedentary), and break frequency and duration were pooled. Higher energy expenditures of different types of breaks (standing, light- or moderate-intensity walking) were associated with lower post-prandial glucose and insulin responses in a dose-dependent manner...

Introduction: Cigarette smoking (CS) remains a major public health concern and has recently been associated with an increased risk of developing acute respiratory distress syndrome (ARDS). Bronchoalveolar lavage (BAL) experiments in human volunteers have demonstrated that active smokers develop increased alveolar-epithelial barrier permeability to protein after inhaling lipopolysaccharide (LPS). Here we tested the hypothesis that short-term whole-body CS exposure would increase LPS-induced lung edema in mice...

Dermatophytosis is the most common fungal infection in cats worldwide and plays an important role in both animal and human health due to their high zoonotic potential. Effective screening is a strong preventive measure and the fungal culture is quite useful but requires full laboratorial experience and it takes a long time to obtain the result. A rapid and accurate screening test for dermatophytosis in cats is crucial for the effective control of disease outbreaks. The aim of this study was to develop and evaluate the diagnostic efficacy of enzyme immunoassays (ELISA and Western blot [WB]) for the rapid and precise diagnosis of dermatophytosis in cats...

Background: The atypical antipsychotic clozapine is effective in treatment-resistant schizophrenia; however, the success or failure of clozapine therapy is substantially affected by the variables that impact the clozapine blood concentration. Thus, elucidating the inter-individual differences in clozapine pharmacokinetics can facilitate the personalized therapy. Methods: Since potential role in clozapine metabolism is assigned to CYP1A2, CYP2C19, CYP2D6 and CYP3A enzymes, the association between the patients' CYP-status (CYP genotypes, CYP expression) and clozapine clearance was evaluated in 92 psychiatric patients...

The preference of modern consumers for high-quality meat has forced breeders to use native breeds to produce capons. Caponization, both chemical and surgical, leads to androgen deficiency and changes in lipid metabolism and results in the accumulation of abdominal, subcutaneous, and intramuscular lipids, which change the sensory values of the meat. The aim of this study was to histologically evaluate selected skeletal muscles from Greenleg Partridge capons and cockerels. We examined lipid localization in the muscular tissue and also assessed both fiber type and fiber diameter in the pectoral muscles...
