Potential adverse public health effects afforded by the ingestion of dietary lipid oxidation product toxins: significance of fried food sources
Exposure of polyunsaturated fatty acid (PUFA)-rich culinary oils (COs) to high temperature frying practices generates high concentrations of cytotoxic and genotoxic lipid oxidation products (LOPs) via oxygen-fueled, recycling peroxidative bursts. These toxins, including aldehydes and epoxy-fatty acids, readily penetrate into fried foods and hence are available for human consumption; therefore, they may pose substantial health hazards. Although previous reports have claimed health benefits offered by the use of PUFA-laden COs for frying purposes, these may be erroneous in view of their failure to consider the negating adverse public health threats presented by food-transferable LOPs therein. When absorbed from the gastrointestinal (GI) system into the systemic circulation, such LOPs may significantly contribute to enhanced risks of chronic non-communicable diseases (NCDs), e.g. , cancer, along with cardiovascular and neurological diseases. Herein, we provide a comprehensive rationale relating to the public health threats posed by the dietary ingestion of LOPs in fried foods. We begin with an introduction to sequential lipid peroxidation processes, describing the noxious effects of LOP toxins generated therefrom. We continue to discuss GI system interactions, the metabolism and biotransformation of primary lipid hydroperoxide LOPs and their secondary products, and the toxicological properties of these agents, prior to providing a narrative on chemically-reactive, secondary aldehydic LOPs available for human ingestion. In view of a range of previous studies focused on their deleterious health effects in animal and cellular model systems, some emphasis is placed on the physiological fate of the more prevalent and toxic α,β-unsaturated aldehydes. We conclude with a description of targeted nutritional and interventional strategies, whilst highlighting the urgent and unmet clinical need for nutritional and epidemiological trials probing relationships between the incidence of NCDs, and the frequency and estimated quantities of dietary LOP intake
A catalog of larval Amphibia in the Yale Peabody Museum
The herpetological collection of Yale University\u27s Peabody Museum of Natural History contains over 1,460 lots of larval amphibians, representing more than 9,000 individuals. Although the majority of the larvae originate from North American localities, especially Connecticut, the collection includes representative holdings from several countries. A catalog of the entire Yale Peabody Museum larval collection is provided here
Responsible access to credit for sole-traders and micro-organizations under unstable market conditions with psychometrics
In a context of market volatility, the growing complexity of financial products, and a shift towards self-employment, there is an increasing demand for inclusive financial services for sole traders and micro-organizations. To address this need, we conducted a study using real-time data from a Fintech lender in the Czech Republic to assess the effectiveness of a new financial literacy based psychometric credit scoring model (PSM) in improving access to finance for micro, small and medium sized enterprises (MSME) sector, particularly sole traders, and micro-organizations, during volatile market conditions. This study affirms that PSMs play a significant role in responsibly including this underserved sector. Specifically, we observed a 30% higher approval rate and a 23% lower default rate when utilizing the PSM versus the traditional credit scoring model (TCSM). Moreover, during the period of substantial market volatility and instability, such as the state-of-emergency during the COVID-19 pandemic, the PSM exhibited a 13% higher approval rate at a 20% lower default rate than the TCSM. This evidence supports the proposition that PSMs offer a viable option for promoting financial inclusion and targeted financial education among MSMEs in the face of instable financial markets
Relationship value benefits of membership programs, heterogeneous stakeholders and museum impact beyond fees
In times of decreasing public funding, cultural institutions such as museums increasingly develop new stakeholder management practices to build a different or more diversified support base. Recently, membership programs have especially been gaining popularity. In this paper, we adopt a relationship value approach to study the poorly understood behaviors of members that can benefit museums beyond membership fees. In particular, we focus on the extent to which membership level and the perceived prestige of the museum drive value co-creation through prestige leveraging. We study this by using a sample of 430 members and non-members of the Hermitage Museum in Amsterdam. We find that membership level is positively related with cross-buying behavior at the museum store and restaurant, and recommending the museum. In addition, these value creating behaviors are mediated by members leveraging the museum's prestige in their social environment. In contrast, we find a negative relationship between membership level and recruiting new members into the program, which could be explained by status dilution effects
