Changes in the microbiological and chemical characteristics of white bread during storage in paper packages modified with Ag/TiO2-SiO2, Ag/N-TiO2 or Au/TiO2.

Microbiological and chemical characteristics of white bread during storage in paper-packages modified with Ag/TiO2-SiO2, Ag/N-TiO2 or Au/TiO2 were investigated. The whiteness and the water retention of the modified packages were slightly superior to those exhibited by the reference sample, as the color of the composite was lighter. The water retention was very good especially for the Ag/TiO2-SiO2-paper.

Primary complement and antibody deficiencies in autoimmune rheumatologic diseases with juvenile onset: a prospective study at two centers.

Background: Our aim was to investigate the prevalence and clinical relevance of inherited complement and antibody deficiency states in a large series of patients with various autoimmune rheumatologic diseases (ARD) with juvenile onset.

Methods: A total number of 117 consecutive patients from 2 tertiary referral hospitals were included in the study. All patients underwent genetic screening for type I C2 deficiency and C4 allotyping.

Typhus Exanthematicus in Romania During the Second World War (1940-1945) Reflected by Romanian Medical Journals of the Time.

This article provides a picture of exanthematic Typhus in Romania during the Second World War: epidemiological aspects of this disease in the inner zone and in the zone of military operations, as well as information about the diagnosis, treatment and prophylaxis of the Typhus in our country during this period.

A novel common large genomic deletion and two new missense mutations identified in the Romanian phenylketonuria population.

The mutation spectrum for the phenylalanine hydroxylase (PAH) gene was investigated in a cohort of 84 hyperphenylalaninemia (HPA) patients from Romania identified through newborn screening or neurometabolic investigations. Differential diagnosis identified 81 patients with classic PAH deficiency while 3 had tetrahydropterin-cofactor deficiency and/or remained uncertain due to insufficient specimen. PAH-genetic analysis included a combination of Sanger sequencing of exons and exon–intron boundaries, MLPA and NGS with genomic DNA, and cDNA analysis from immortalized lymphoblasts.

Cognitive synergy in groups and group-to-individual transfer of decision-making competencies.

In a field study (148 participants organized in 38 groups) we tested the effect of group synergy and one's position in relation to the collaborative zone of proximal development (CZPD) on the change of individual decision-making competencies. We used two parallel sets of decision tasks reported in previous research to test rationality and we evaluated individual decision-making competencies in the pre-group and post-group conditions as well as group rationality (as an emergent group level phenomenon). We used multilevel modeling to analyze the data and the results showed that members of synergetic groups had a higher cognitive gain as compared to members of non-synergetic groups, while highly rational members (members above the CZPD) had lower cognitive gains compared to less rational group members (members situated below the CZPD).

Children's and adolescents' snacking: interplay between the individual and the school class.

Objective: In schools, perceived norms of classmates facilitate but can also inhibit unhealthy food intake in children and adolescents. However, the role of actual class behaviors and attitudes is less established. Thus, the present study examined classmates' actual eating behavior and food preferences in relation to actual food intake.

GFAP and antibodies against NMDA receptor subunit NR2 as biomarkers for acute cerebrovascular diseases.

We studied whether the serum levels of glial fibrillary acidic protein (GFAP) and of antibodies against the N-methyl-d-aspartate receptor subunit NR2 (NR2 RNMDA ) can discriminate between intracerebral haemorrhage (ICH) and ischaemic stroke (IS) in stroke patients. We prospectively recruited patients with suspected stroke (72 confirmed) and 52 healthy controls. The type of brain lesion (ICH or IS) was established using brain imaging.

Structure, mineralogy, and microbial diversity of geothermal spring microbialites associated with a deep oil drilling in Romania.

Modern mineral deposits play an important role in evolutionary studies by providing clues to the formation of ancient lithified microbial communities. Here we report the presence of microbialite-forming microbial mats in different microenvironments at 32°C, 49°C, and 65°C around the geothermal spring from an abandoned oil drill in Ciocaia, Romania. The mineralogy and the macro- and microstructure of the microbialites were investigated, together with their microbial diversity based on a 16S rRNA gene amplicon sequencing approach.

Characterizing psychological dimensions in non-pathological subjects through autonomic nervous system dynamics.

The objective assessment of psychological traits of healthy subjects and psychiatric patients has been growing interest in clinical and bioengineering research fields during the last decade. Several experimental evidences strongly suggest that a link between Autonomic Nervous System (ANS) dynamics and specific dimensions such as anxiety, social phobia, stress, and emotional regulation might exist. Nevertheless, an extensive investigation on a wide range of psycho-cognitive scales and ANS non-invasive markers gathered from standard and non-linear analysis still needs to be addressed.

Sequential cobalt magnetization collapse in ErCo2: beyond the limits of itinerant electron metamagnetism.

The itinerant electron metamagnetism (IEM) is an essential physical concept, describing magnetic properties of rare earth - transition metal (R-TM) intermetallics, demonstrating technologically important giant magnetoresistance and magnetocaloric effects. It considers an appearance of TM magnetization induced by spontaneous magnetization of surrounding R atoms, which provides significant response of the magnetic and transport properties on variation of external parameters (temperature, pressure, magnetic field) due to strong coupling between magnetic sublattices. The RCo2 compounds were generally considered as model systems for understanding of basic properties of IEM intermetallics.

A couple-focused intervention to prevent postnatal smoking relapse: PRISM study design.

Background: Maternal smoking is one of the most modifiable factors with clear adverse effects for the fetus and the entire family. Addressing the dearth of pregnancy smoking interventions with partner support, PRISM (Prevent Relapse In SMoking) is a partnership between a research institution and the two largest state-owned obstetrics and gynecology clinics in Cluj-Napoca, Romania. The study will assess the efficacy of a couple-focused telephone-counseling program to prevent smoking relapse among mothers who quit smoking closely before or during pregnancy.

Parish registers from Transylvania - sources of the history of medicine (late 18th - early 20th centuries).

This paper aims to analyse the typology of medical-historical information provided by parish registers from Transylvania - a category of primary sources used mainly by historical demographers. The approach is descriptive and prospective in character: it creates a typology of the medical information to be found in the sources, while highlighting possible research directions and approaching a series of methodological and interpretation issues. The parish registers contain references to medical actors (the midwife, the physician, the death inspector), to medical activities (vaccination), and to events regarding the history of medicine (multiple births, infant mortality, death-causing diseases and accidents, epidemics, etc.

Identification and characterization of major histocompatibility complex class IIB alleles from three species of European ranid frogs.

Immune genes of the major histocompatibility complex (MHC) are among the most polymorphic genes in the vertebrate genome. Due to their polymorphic nature, they are often used to assess the adaptive genetic variability of natural populations. This study describes the first molecular characterization of 13 partial MHC class IIB sequences from three European ranid frogs.

Longitudinal and concurrent links between memory span, anxiety symptoms, and subsequent executive functioning in young children.

It has been conjectured that basic individual differences in attentional control influence higher-level executive functioning and subsequent academic performance in children. The current study sets out to complement the limited body of research on early precursors of executive functions (EFs). It provides both a cross-sectional, as well as a longitudinal exploration of the relationship between EF and more basic attentional control mechanisms, assessed via children's performance on memory storage tasks, and influenced by individual differences in anxiety.

Quantitative assessment of the masseter muscle's elasticity using Acoustic Radiation Force Impulse.

Aims: The study proposes Acoustic Radiation Force Impulse (ARFI) assessment of the masseter muscle elasticity in the healthy population and in patients who have undergone head and neck radiation therapy.

Patients And Methods: Twenty-five healthy controls constituted group A, and 13 patients who had underwent radiotherapy (35Gy minimum) formed group B. ARFI was performed bilaterally in the periphery (P) and the muscle center (C), in relaxation and contraction.

Assessing health literacy in rural settings: a pilot study in rural areas of Cluj County, Romania.

Health literacy improves knowledge and builds skills to help individuals make appropriate decisions regarding their health. Over the past 20 years, several studies have described associations between health literacy and health outcomes. With respect to Romania, evidence is scarce on the level of health literacy, as well as on its determinants.

Magnetic behaviour of Er1-xZrxFe2 intermetallic compounds.

In this work, the structural and magnetic properties of Er1-xZrxFe2 (0.1 ≤ x ≤ 0.4) were investigated.

Current issues and future directions in evidence-based child protection practices: a view from Romania.

The constantly changing nature of social care practice necessitates continuous development of educational programs to prepare current practitioners. Basing social work practice on methodologically sound research evidence is an appealing prospect for the child protection services. However, Romania, once considered an Eastern European model for child welfare policy and practice, is somehow lagging behind.

When interference helps: increasing executive load to facilitate deception detection in the concealed information test.

The possibility to enhance the detection efficiency of the Concealed Information Test (CIT) by increasing executive load was investigated, using an interference design. After learning and executing a mock crime scenario, subjects underwent three deception detection tests: an RT-based CIT, an RT-based CIT plus a concurrent memory task (CITMem), and an RT-based CIT plus a concurrent set-shifting task (CITShift). The concealed information effect, consisting in increased RT and lower response accuracy for probe items compared to irrelevant items, was evidenced across all three conditions.

Accumulation of tissue macrophages and depletion of resident macrophages in the diabetic thymus in response to hyperglycemia-induced thymocyte apoptosis.

Aims: We investigated the dynamics and morphology of thymus macrophages in response to thymus involution caused by hyperglycemia. Thymus is an organ affected early and dramatically after the onset of diabetes, losing most of the thymocyte populations but diabetes's impact on the components of the thymus stroma is largely unknown.

Methods: Rats were injected with streptozotocin and thymus weight, body weight, and glycemia were measured at various time points.

Promoting health in rural Transylvania, Romania. a descriptive analysis of health promotion activities.

Even though efforts are made to reduce health disparities, promote health for all social groups and improve health outcomes, inconsistencies still exist. Existing evidence shows that lack of funding, lack of properly trained workforce, as well as heavy workload on health care workers, are the most employed explanations for the limited number of health promotion interventions in the area. This paper presents the results of a descriptive study that pursues to render a comprehensive image of health promotion efforts undertaken in rural Transylvania, Romania.

Analytical challenges and recent advances in the determination of estrogens in water environments.

Estrogens have been shown to be present in the water compartment, mainly due to the inefficient removal in wastewater treatment plants (WWTP). The concentrations of these compounds, although very low (low ng/L), are sufficient to induce estrogenic responses and alter the normal reproduction and development of wildlife organisms. The compounds have been determined, by a variety of analytical procedures, in the influents and effluents of WWTP, fresh waters, rivers, and even drinking waters.
