ADHD and the avoidance of mental effort: the role of response inhibition and avoidance motivation.

Objective: The tendency of people with ADHD to avoid tasks that require mental effort impacts their academic achievement. Findings in the literature suggest that children with ADHD find cognitive tasks more effortful and uncomfortable than their typically developing peers. However, neuropsychological processes contributing to this remain unclear.

The Effect of Maternal Dietary Selenium Supplementation on Blood Antioxidant and Metabolic Status of Ewes and Their Lambs.

This study investigated the effect of dietary selenium supplementation (organic and inorganic) of late-gestation ewes on blood selenium concentrations and metabolic and antioxidant status indicators in ewes and their lambs. In addition, the efficacy of selenium transfer from ewes to lambs during the suckling period was determined. The study was conducted on 30 Merinolandschaf ewes and their lambs and lasted four months.

Problem gambling in adolescents: what are the psychological, social and financial consequences?

Background: The paper examines the roles of sociodemographic traits, family quality and risk behaviour in adolescent problem gambling, with focus on the psychological, social and financial consequences from the socio-ecological model approach. This model emphasizes the most important risk-protective factors in the development and maintenance of problem gambling on an individual level, a relationship level, as well as a community and societal level.

Methods: The research was done using the Canadian Adolescent Gambling Inventory with a sample of 366 participants, 239 females (65.

Cyberbullying and emotional distress in adolescents: the importance of family, peers and school.

The paper examines the role of socioeconomic status, family, parenting styles, peer relations and school factors in cyber-bullying with focus on emotional consequences. A survey was conducted with 259 participants (202 female) aged 19-25. 58,1% experienced some form of cyber violence, and 56,8% did not bully others.

The potential of chironomid larvae-based metrics in the bioassessment of non-wadeable rivers.

The chironomid community in non-wadeable lotic systems was tested as a source of information in the construction of biological metrics which could be used into the bioassessment protocols of large rivers. In order to achieve this, we simultaneously patterned the chironomid community structure and environmental factors along the catchment of the Danube and Sava River. The Self organizing map (SOM) recognized and visualized three different structural types of chironomid community for different environmental properties, described by means of 7 significant abiotic factors (a multi-stressor gradient).

The Effect of Autochthonous Starter Culture, Sugars and Temperature on the Fermentation of Slavonian Kulen.

In this study, the effect of an isolated and well-characterised autochthonous starter culture, glucose and maltodextrin (=0.8%) and temperatures of 12 and 20 °C on fermentation and quality of Slavonian kulen produced using the traditional technology and recipe were investigated. Physicochemical and microbiological analyses were carried out after 20 days of fermentation.

Biological control of chestnut blight in Croatia: an interaction between host sweet chestnut, its pathogen Cryphonectria parasitica and the biocontrol agent Cryphonectria hypovirus 1.

Background: Chestnut blight, caused by the fungus Cryphonectria parasitica, is a severe chestnut disease that can be controlled with naturally occurring hypoviruses in many areas of Europe. The aim of this research was to measure the effect of different Cryphonectria hypovirus 1 (CHV1) strains on the growth of the fungal host and select strains that could potentially be used for human-mediated biocontrol in forests and orchards, and to investigate whether and how chestnut-fungus-virus interactions affect the development and growth of the lesion area on cut stems.

Results: Two Croatian CHV1 strains (CR23 and M56/1) were selected as potential biocontrol agents.

Effect of UVC radiation on mouse fibroblasts deficient for FAS-associated protein with death domain.

Purpose: Ultraviolet (UV) radiation-induced apoptosis enabled us to study the mechanism of DNA damage and to investigate how cells avoid consequences of damaged DNA. Cells with extensive DNA damage activate extrinsic and intrinsic pathways of apoptosis. The extrinsic pathway is coupled to a FAS-associated protein with death domain (FADD), an adaptor protein molecule necessary for mediating apoptotic signals through the cell.

Epicardial Adipose Tissue Is Nonlinearly Related to Anthropometric Measures and Subcutaneous Adipose Tissue.

Introduction. Adipose tissue is the largest endocrine organ, composed of subcutaneous (SAT) and visceral adipose tissue (VAT), the latter being highly associated with coronary artery disease (CAD). Expansion of epicardial adipose tissue (EAT) is linked to CAD.

Oxidative stress in leaves of two olive cultivars under freezing conditions.

Olive is one of the most important cultivated Mediterranean plants. In order to determine the differences in frost resistance of two, two-year-old olive cultivars (Olea europaea cv. Leccino and cv.

PSII photochemistry in vegetative buds and needles of Norway spruce (Picea abies L. Karst.) probed by OJIP chlorophyll a fluorescence measurement.

Vegetative buds represent developmental stage of Norway spruce (Picea abies L. Karst.) needles where chloroplast biogenesis and photosynthetic activity begin.

Effect of natural biostimulants on yield and nutritional quality: an example of sweet yellow pepper (Capsicum annuum L.) plants.

Background: Modifications in growing techniques can affect the yield and nutritional quality of various cultivated plant species. Owing to its high nutritional value, pepper (Capsicum annuum L.) was used in this study as a model plant to investigate the effect of natural biostimulants on yield and fruit quality parameters under conditions of reduced fertilisation.

Inhibitory properties of nucleotides with difluoromethylenephosphonic acid as a phosphate mimic versus calf spleen purine nucleoside phosphorylase and effect of these analogues on the viability of human blood lymphocytes.

Several cyclic and acyclic 6-keto purine nucleotides with difluoromethylenephosphonic acid as phosphate mimic are proved to be potent inhibitors of mammalian purine nucleoside phosphorylase (PNP). Antiproliferative activity of these analogues on the growth of human blood lymphocytes was tested by MTT assay. Compared to inhibitory effects on the growth of human blood T-lymphocytes isolated from healthy donors, all analogues significantly slow down proliferation of T-lymphocytes isolated from patients with autoimmune thyroid disease--Hashimoto's thyroiditis.

Population dynamic of Aedes vexans and Ochlerotatus sticticus in flooded areas of the River Drava in Osijek, Croatia.

Populations of adult mosquitoes occurring in the Osijek area in eastern Croatia were monitored from May 1995 to September 2000 with Centers for Disease Control-style traps baited with dry ice. A total of 106,663 adults was caught, ranging from 0 (several times) to 21,120 in May 1995. The mosquitoes captured represented 18 species.
