Determination of PAH Contamination in Breast Milk Samples from Hungarian Volunteering Mothers, Using HPLC-FLD.

(1) The evidence is mounting that polycyclic aromatic hydrocarbons (PAHs) are a class of hazardous organic compounds with established carcinogenic and toxic properties. Humans may be exposed to PAHs through several different routes, including diet, inhalation, and dermal contact. There is also a possibility that they could transfer into breast milk following maternal exposure, which could potentially endanger breastfeeding infants.

The Impact of Qualification and Hospice Education on Staff Attitudes during Palliative Care in Pediatric Oncology Wards-A National Survey.

Body Mass Index during Gluten-Free Diet in Patients with Celiac Disease.

The association of clinical variables with body mass index (BMI) and changes experienced during a gluten-free diet (GFD) in celiac disease (CD) is not well established. In this retrospective cohort study, we aimed to investigate factors aligned with baseline and a follow-up regarding BMI in CD cases diagnosed at the University of Pécs (Hungary). Data were collected regarding gender, age, clinical presentation, histology, serology, extraintestinal manifestations, and BMI upon diagnosis and during follow-up.

Higher Availability of Long-Chain Monounsaturated Fatty Acids in Preterm than in Full-Term Human Milk.

While the role of n-3 and n-6 long-chain polyunsaturated fatty acids (LCPUFAs) in the maturation of the infantile nervous system is extensively studied and relatively well-characterized, data on the potential developmental importance of the n-9 long-chain monounsaturated fatty acid (LCMUFA), nervonic acid (NA, C24:1n-9) are scarce and ambiguous. Therefore, the aim of the present study was to reanalyze our available data on the contribution of NA and its LCMUFA precursors, gondoic acid (C20:1n-9) and erucic acid (EA, C22:1n-9) to the fatty acid composition of human milk (HM) during the first month of lactation in mothers of both preterm (PT) and full-term (FT) infants. HM samples were obtained daily during the first week of lactation, and then on the 14th, 21st, and 28th days.

Cognitive functioning and clinical characteristics of children with non-syndromic orofacial clefts: A case-control study.

Introduction: The higher rate of neuropsychiatric disorders in individuals with non-syndromic orofacial clefts has been well documented by previous studies. Our goal was to identify children with non-syndromic orofacial clefts that are at risk for abnormal neurodevelopment by assessing their developmental history and present cognitive functioning.

Materials And Methods: A single-center, case-controlled study was carried out at the Department of Pediatrics of the University of Pécs in Hungary.

High Prevalence of Non-Vaccinated Oncogenic Human Papillomavirus Genotypes in High-Grade Squamous Intraepithelial Lesions of the Cervix: Thought-Provoking Results of a Detailed HPV Genotype Analysis.

Identification of HPV infection is usually performed on cytological specimens, despite the often transient virus types. HPV profile analysis of pathologically confirmed lesions can also be performed on formalin-fixed paraffin-embedded (FFPE) cone samples and should be taken as standard during follow-up. We compared HPV profiles of cytological and FFPE specimens of women diagnosed with HSIL.

[Early and late complications of hyperglycemic extremely low birth-weight infants].

During recent decades, the perinatal mortality of extremely low-birth weight infants has decreased. An important task is to recognize complications of prematurity. We made an attempt to explore the relationship between complications of prematurity and neonatal hyperglycemia.

Distribution of bioactive factors in human milk samples.

Background: Breast milk provides nutrition for infants and also contains a variety of bioactive factors that influence the development of the newborn. Human milk is a complex biological fluid that can be separated into different layers (water phase and lipid phase with its component water and lipid fractions). It can affect the developing human body along the whole length of the gastrointestinal tract, and through the circulation, its factors may reach every organ.

Cytoplasmic expression of β-catenin is an independent predictor of progression of conventional renal cell carcinoma: a simple immunostaining score.

Aims: The aims of this study were to investigate the potential of β-catenin as a biomarker for predicting cancer-specific survival, and to find a reproducible mode of evaluation of immunohistochemistry.

Methods And Results: β-Catenin expression was analysed by immunohistochemistry in a cohort of 488 patients with conventional renal cell carcinoma (RCC) operated on between 2000 and 2010. The association between β-catenin expression and cancer-specific survival was assessed with univariate and multivariate Cox regression models in relation to conventional clinical pathological prognostic factors, and by Kaplan-Meier survival analysis with the log rank test.

Effect of an educational intervention on Hungarian adolescents' awareness, beliefs and attitudes on the prevention of cervical cancer.

The alarming national data on the mortality and morbidity rates of cervical cancer as well as the results of a Hungarian survey demonstrating adolescents' low level of understanding of human papillomavirus (HPV) infection and HPV vaccination encouraged the authors to conduct an educational intervention. The aim of this survey was to explore the impact of a brief, HPV-focused program on adolescents' knowledge, beliefs and attitudes. A self-administered anonymous questionnaire was completed by 394 male and female adolescents in September, 2010, in Hungary.

Difficulties in the prevention of cervical cancer: adults' attitudes towards HPV vaccination 3 years after introducing the vaccine in Hungary.

Cervical cancer is one of the most prevalent gynaecological malignancies worldwide. The Hungarian incidence and mortality of this disease take the 4th-5th places within the European Union. A survey including 785 male and female adults was conducted to assess the knowledge and attitudes concerning HPV vaccination.

Differential scanning calorimetry study of glycerinated rabbit psoas muscle fibres in intermediate state of ATP hydrolysis.

Background: Thermal denaturation experiments were extended to study the thermal behaviour of the main motor proteins (actin and myosin) in their native environment in striated muscle fibres. The interaction of actin with myosin in the highly organized muscle structure is affected by internal forces; therefore their altered conformation and interaction may differ from those obtained in solution. The energetics of long functioning intermediate states of ATP hydrolysis cycle was studied in muscle fibres by differential scanning calorimetry (DSC).

Lovastatin possesses a fungistatic effect against Candida albicans, but does not trigger apoptosis in this opportunistic human pathogen.

Lovastatin inhibited the growth of Candida albicans in a fungistatic way. Although it triggers apoptosis in a great variety of eukaryotic cells, including many tumour cell lines, lovastatin failed to provoke apoptotic events in this human pathogen. The fungistatic behaviour of this statin might arise from its negative influence on membrane fluidity.

Effect of polycyclic aromatic hydrocarbons on erythrocyte membranes by DSC and EPR.

Differential scanning calorimetry (DSC) and electron paramagnetic resonance spectroscopy (EPR) experiments were performed on human erythrocyte membranes and 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC) model systems in order to study the effect the polycyclic aromatic hydrocarbons on lipid structure and dynamics. Eight different compounds among others naphthalene and pyrene were compared, which occur in significant concentrations in dust collected from the air in large cities. Experiments using spin label technique showed that the compounds induced mobility changes in the lipid region in the environment of the fatty acid probe molecules incorporated into the membranes.
