Lysobacter may drive the hormetic effects of Pb on soil alkaline phosphatase
Abstract It has become increasingly recognized that hormesis phenomena exist in soil ecosystem, but the research on the hormetic responses of soil enzymes are still limited. This study was conducted to investigate the hormetic effects of lead (Pb) on the activity of soil alkaline phosphatase (ALP) and the associated microbial groups. Soils were treated by adding Pb (NO3)2 solution with 0, 10, 100, 500, 1000, 2000, 4000, and 5000 mg/kg of Pb, respectively. A moist heat sterilization...

Analysis of vitellogenin by histochemical method as an indicator of estrogenic effect in male Danio rerio exposed to metals
Abstract Several chemicals present in the aquatic environment have the ability to alter the endocrine system of aquatic organisms, including the metals cadmium (Cd) and zinc (Zn). In males, a tool to analyze this effect is the vitellogenin (VTG) detection, a protein with defined function in the yolk production and subsequent aid to embryo-larval development. This protein is produced just by females and can be detected by simple and cheap methods such as histochemical method. Thus,...

Catalytic efficiency of the eggshell calcined and enriched with glycerin in the synthesis of biodiesel from frying residual oil
Abstract Currently, there are several studies using calcium oxide, calcium alkoxide, and calcium hydroxide for biodiesel production. However, there is still a lack of studies highlighting the use of calcium diglyceroxide (calcium oxide enriched with glycerin in the presence of methanol) as a catalyst in the transesterification process. Therefore, the present work aimed to investigate the catalytic efficiency and reutilization of the eggshell calcined and enriched with glycerin...

Effect of arrangement and quantity of epipremnum aureum on work efficiency and subjective perceptions
Abstract Plants can improve indoor air quality, and affect the work efficiency and subjective perceptions. However, the conclusions of existing experiments regarding how plants affect work efficiency are not uniform. To further explore this subject, this study designed five different working conditions, and selected a variety of “general tasks” and “tasks requiring concentration” as operational tasks. The effects of the plant arrangement and quantity on work efficiency were studied...

Long-term cadmium exposure affects cell adhesion and expression of cadherin in the male genital organ of Pardosa pseudoannulata (Bösenberg & Strand, 1906)
Abstract Pardosa pseudoannulata (Araneae: Lycosidae), as an important predator of crop pests, has served as a strong driver for ecological regulation of pests. Cadmium (Cd) is a toxic heavy metal widely distributed in the soil in China, which not only seriously pollutes the ecological environment, but also poses a great threat to the survival of organisms. Palpal bulbs are the genital organs of male spiders, playing an important role in reproductive physiology. However, the effects...

Learning feature spaces for regression with genetic programming
Abstract Genetic programming has found recent success as a tool for learning sets of features for regression and classification. Multidimensional genetic programming is a useful variant of genetic programming for this task because it represents candidate solutions as sets of programs. These sets of programs expose additional information that can be exploited for building block identification. In this work, we discuss this architecture and others in terms of their propensity for...

Can an Integrated Constructed Wetland in Norfolk Reduce Nutrient Concentrations and Promote In Situ Bird Species Richness?
Abstract Integrated Constructed Wetlands (ICWs) are potentially effective tools in the effort to restore aquatic ecosystems, and also they incorporate multiple co-benefits. An ICW was constructed in Norfolk, UK, to address the degradation of a stream and lake receiving treated effluent from a small Sewage Treatment Works (STW). Results demonstrated that: (1) nutrient concentrations significantly reduced from the ICW influent to the effluent (percentage reductions: total phosphorus...

An update on familial nonmedullary thyroid cancer
Abstract Familial nonmedullary thyroid cancer (FNMTC) constitutes 3–9% of all thyroid cancer cases. FNMTC is divided into two groups: syndromic and nonsyndromic. Nonsyndromic FNMTC is more common as compared with syndromic FNMTC. In syndromic FNMTC, patients are at risk of nonmedullary thyroid cancer (NMTC) and other tumors, and the susceptibility genes are known. In nonsyndromic FNMTC, NMTC is the major feature of the disease and occurs in isolation with an autosomal dominant...
