As shown previously, Euglena cells grown in Hutner’s medium in the dark without agitation accumulate wax as well as paramylum, and contain proplastids showing no internal structure except for a single prothylakoid existing close to the envelope. When the cells are transferred to an inorganic medium containing ammonium salt and the cell suspension is aerated in the dark, the wax was oxidatively metabolized, providing carbon materials and energy 23 for some dark processes of plastid development. Under these conditions, pyrenoid-like structures (called “pro-pyrenoids”) are formed at the sites adjacent to the prolamel larbodies (PLB) localized in the peripheral region of the proplastid. The single prothylakoid becomes paired with a newly formed prothylakoid, and a part of the paired prothylakoids is extended, with foldings, in to the “propyrenoid”. In this study, we observed a concentration of RuBisCO in the “propyrenoid” of Euglena gracilis strain Z using immunoelectron microscopy.

Background: Suicide among children under the age of 15 years is a leading cause of death. Aims: The aim of the current study is to identify demographic, psychosocial, and psychiatric factors associated with child suicides. Method: Using external causes of deaths recorded in the Queensland Child Death Register, a case-control study design was applied. Cases were suicides of children (10–14 years) and adolescents (15–17 years); controls were other external causes of death in the same age band. Results: Between 2004 and 2012, 149 suicides were recorded: 34 of children aged 10–14 years and 115 of adolescents aged 15–17 years. The gender asymmetry was less evident in child suicides and suicides were significantly more prevalent in indigenous children. Children residing in remote areas were significantly more likely to die by suicide than other external causes compared with children in metropolitan areas. Types of precipitating events differed between children and adolescents, with children more likely to experience family problems. Disorders usually diagnosed during infancy, childhood, and adolescence (e.g., ADHD) were significantly more common among children compared with adolescents who died by suicide. Conclusion: Psychosocial and environmental aspects of children, in addition to mental health and behavioral difficulties, are important in the understanding of suicide in this age group and in the development of targeted suicide prevention.

The automotive sector is one of the fastest growing sectors of economy. The increasing amount of cars both in Polish and world roads results in the immeasurable benefits associated with the goods and human transport. On the other hand, this phenomenon caused the contamination of the environment. During the fuel combustion in petrol or diesel engines, the harmful gases, for example CO2, NOx and SOx are emitted. Apart from the negative impact on the environment, the emission of the aforementioned gases results in the deterioration of human conditions, as well as, the development of civilization diseases. In order to minimalize the harmful influence of an automotive industry on the environment, new technologies which can reduce the consumption of fuel or limit the fumes emission are developed. The first part of paper presents new solutions in an automotive sector which influence on the decline of the negative impact of automobiles on the environment. Additionally, proposed solutions affect the development of a car industry, taking into consideration environmental aspects.

Environmental health is referring to the health of people in relation to environmental quality. Due to rapid urbanisation, more people are living in urban neighbourhoods. Urban planning and design aspects including the neighbourhood environment are potentially affecting the human healthy lifestyle and health condition. Thus, the relationship between Malaysian neighbourhood environmental aspects and human health has become the concern of this research. One of the neighbourhood units in Shah Alam city had been chosen as the study area for this purpose. Questionnaire survey had been carried out to examine the health condition and physical activeness of residents. Besides, the perception of residents on the quality of neighbourhood environmental aspects also had been collected in the questionnaire survey. The health condition of residents was measured by non-communicable diseases (NCD) and the physical activeness was measured in duration as well as the frequency of physical exercise activities. The study found that the quality of neighbourhood environmental aspects significantly increased the physical activeness of respondents. The physical activeness was positively associated with human health as measured in NCD (heart diseases and high blood pressure, HBP). It shows that neighbourhood environmental (physical and social) aspects are potentially affecting the healthy life of people living in the neighbourhood.Keywords: Healthy life, Neighbourhood environment, Non-communicable diseases (NCD), Physical activeness, Quality.
