  • Environmental Factors as Determinants of Health in New Jersey, USA

    • Authors: Robert P. Blauvelt
      Abstract: There is a well-documented association between socioeconomic factors and community health. While environmental conditions are considered in most public health evaluations, they have the least weighted values of all the metrics measured. The U.S. state of New Jersey has a very robust, long-standing environmental protection program combined with some of the highest educational attainment, employment, and income levels in the country. These conditions may have re-positioned or re-prioritized those societal factors that traditionally dominate health outcomes, placing greater emphasis on environmental factors. This paper seeks to evaluate whether in New Jersey at the county level the long-established connection between health status and environmental quality conditions needs to be re-defined. Because of its high per capita income, well-educated population, and strong industrial and service sector employment base, New Jersey residents are fairly healthy, and New Jersey is generally placed within the top ten healthiest places to live in the United States. Thus, this state is well positioned to assess the relative importance that releases to air, water, and soil may play in determining health outcomes. This is due to the state’s long history of significant pollution of its air, water, and soil coupled with a strong, effective regulatory program that slowly is achieving meaningful improvements to environmental quality.Five data sets related to discharges to the air, water, or soil were compiled and tested separately against two New Jersey specific community health indices. The health surveys include the New Jersey Hospital Association’s 2019 report on social gaps and their impact on health (CHART) and the nationwide America’s Health Rankings (UHF). A Pearson’s product moment correlation coefficient was used to compare each state’s health ranking – both CHART and UHF - with the independent variable, environmental exposure data sets. The analysis found that there are no meaningful correlations between the environmental exposure data sets and the CHART or UHF county health rankings. This suggests that environmental factors may be over-weighted given the level of state and federal regulatory protection programs already in place within New Jersey. Policy makers should now consider two shifts in public health strategy: encouraging economic growth in areas with underperforming health outcomes so as to maximize those determinants that do most impact positive outcomes (insurance, income, etc.) coupled with aggressive enforcement of existing environmental regulations to protect communities from the possible consequences of that expanded development.

  • Building a Conceptual Framework from Polyvagal Theory to Explore Effect of
           Maternal Speech on Neural Development in Premature Infants

    • Authors: Khlood Bubshait
      Abstract: The objective of this review was to evaluate the application of Polyvagal theory to: (1) explore relationships between maternal speech and neural development in premature infants; (2) explain influences of moderators, mediators, and confounding variables of early developmental exposure to maternal speech on neural development in premature infants. A positivist ontological approach was undertaken to explore and evaluate the application of Polyvagal theory in the research area of the effect of maternal speech on neural development or heart rate variability in premature infants. The Polyvagal theory was determined to be an effective theory for describing the effect of early developmental exposure to maternal speech on neural development. Major propositions are presented based on the proposed conceptual model, which integrates previous research on exposure to maternal speech, to ultimately enhance neural development in premature infants.

  • Maize Milling and Modifying Atmospheric Conditions Limit Formation of
           Aflatoxin B1 by Aspergillus Flavus

    • Authors: Benigni Alfred Temba; Gaymary George Bakari
      Abstract: Occurrence of mycotoxins in foods poses a serious health concern all over the world. Aflatoxin B1 (AFB1) is the most toxic, with widest occurrence in various foods, but mainly in cereals and nuts and its accumulation depends on substrate and environmental factors. This study investigated the how physical status (milling) of maize kernels and atmospheric conditions (aeration, moisture and temperature) affect production of aflatoxin B1 by Aspergillus flavus (ATCC 28862). Intact kernels and flour were incubated for up to 20 days in open and partially sealed petri dishes under controlled temperatures of 25 ºC, 30 ºC and 37 ºC and initial moisture contents of 27%, 22%, 18%, 15% and 12%. It was found that on average, significantly higher (p < 0.05) aflatoxin B1 level was accumulated in intact kernels (145.7 µg/kg) as compared to milled kernels (2.2 µg/kg). Also, none of the samples incubated under partially sealed conditions, compared to up to 100% of the samples incubated in open atmosphere had detectable levels of aflatoxin B1 after 20 days. Fungal growth was not affected by milling or aeration, but sporulation was low at 37 ºC and high at 25 ºC and 30 ºC. The findings of this study provide baseline information on how conditions can be modified to control postharvest accumulation of aflatoxin B1 in cereals.

  • Isolation of Xylanase Producing Strains, Optimization of Fermentation
           Conditions and Research on Enzymatic Properties

    • Authors: Ji Huilong; Gao Xin, WU Wenxuan, Ma Zhuang, Qing Qing
      Abstract: In this study, we successfully isolated a strain of Aspergillus oryzae TR08, which produced xylanase secreted to the outside of the cell productively. The enzyme activity and specific activity in the fermentation broth of this strain reached peak values of 451 IU/mL and 1963 IU/mg after 156 h of fermentation. A single factor experiment was designed, and it was found that the strain was adjusted to the initial pH of the fermentation broth to 7.5 in a shaker at 180 rpm and 32 °C. After 156 h of fermentation, the enzyme activity reached a maximum of 1264 IU/mL. The optimal reaction temperature and pH value of the xylanase were 55 °C and 7.5, respectively, and it had excellent acid and alkali resistance and a wide pH activity range. The xylanase was increased the catalytic activity by 15% in 0.25 mM Fe3+, and the biological activity of the enzyme was not affected in the sodium dodecyl sulfate environment.
