A Review: Depolymerization of Lignin to Generate High-Value Bio-Products: Opportunities, Challenges, and Prospects

Lignin is identified as a promising candidate in renewable energy and bioproduct manufacturing due to its high abundance, polymeric structure, and biochemical properties of monomers. Thus, emerging opportunities exist in generating high-value small molecules from lignin through depolymerization. This review aims at providing an overview of the major technologies of lignin depolymerization. The feasibility of large-scale implementation of these technologies, including thermal, biological, and chemical depolymerizations, are discussed in relation to potential industrial applications. Lignin as a renewable alternative to petroleum-based chemicals has been well documented. This review attempts to emphasize potential applications of lignin-derived monomers and their derivatives as bioactives in food, natural health product, and pharmaceutical sectors. The critical review of the prospects and challenges of lignin-derived bioproducts reveals that the advancement of research and development is required to explore the applications of depolymerization of lignins to their full potential.

Controlling The Monster: Exploring Constructions Of Women And Their Bodies In Endometriosis Apps

<p>People globally increasingly use digital applications (apps) to manage their health and health conditions. In particular, women commonly use apps to understand and manage female reproductive issues. Some apps target women with endometriosis, a common but poorly understood condition primarily affecting women. The aim of the current research was to explore how endometriosis apps constructed endometriosis and people with endometriosis, how people with endometriosis were positioned, and the potential implications of this positioning for app users. Multimodal critical discourse analysis (MCDA) was used to systematically examine dominant meanings produced by visual and linguistic features (i.e. colour, imagery, text and interactive app functionality) of five endometriosis apps from the USA, New Zealand and Singapore. Results demonstrated that apps drew on biomedical and biological discourses to construct endometriosis as a complex and confusing disease of the female reproductive body. This positioned biomedical and natural health professionals as knowledgeable experts about endometriosis while minimising women’s experiential knowledge of their bodies. Apps drew on intersecting postfeminist, neoliberal and healthist discourses to construct women with endometriosis as responsible for self-tracking many physical, emotional and behavioural experiences. Self-tracking was constructed as generating data that was meaningfully interpreted by app algorithms and experts to help women understand and manage their endometriosis. Dominant management recommendations (i.e. biomedical interventions; lifestyle changes) aligned with hegemonic ideals of traditional and neoliberal femininity. These findings align with previous feminist research findings that mainstream endometriosis discourse reflects androcentric biases in medical knowledge and that health apps targeting women often reinforce neoliberal and postfeminist ideals. Therefore, dominant discourses about endometriosis and female biology that pathologise women’s bodies and behaviours limit the potential for apps to offer women empowered and agentic subject positions.</p>

Identifying gaps in consumer health library collections: a retrospective review

Background: The objective of this study was to determine if search request forms, which are used when a patron’s request for information cannot be fulfilled at the time of contact with the library team, can be used to identify gaps in consumer health library collections.Case Presentation: Search request forms were collected from 2013 to 2020 and analyzed independently by two reviewers. Search request forms were included if they were complete and contained a record of how the request was fulfilled. Descriptive statistics were used to summarize patron characteristics. Search request forms were iteratively coded to identify themes in the data and determine if resources provided to patrons could be found within the library collection. The study team subsequently reviewed search request forms to determine reasons for identified gaps. Two hundred and forty-nine search request forms were analyzed. Six main content themes were identified: 1) understanding the cancer diagnosis, 2) cancer treatments, 3) understanding disease prognosis, 4) support during and after treatment, 5) natural health products and therapeutic effects in oncology, and 6) research literature. The majority of patrons were patients (53%). Over half (60%) of the submitted search request forms reflected collection gaps, and many (16%) contained queries for information about rare cancer diagnoses. The main reason that queries could not be satisfied was that there was limited consumer health information on the requested topics (53%).Conclusions: Search request forms are a useful resource for assessing gaps in consumer health library collections.

Strategic Responses to New Zealand-China Free Trade Agreement: A Case Study of New Zealand Natural Health Products Industry

<p>The rise of global consumption, as well as technological innovation in transportation and telecommunications, have increased international exchange of goods, services and factors of production. Economic globalization in terms of production and markets has been accompanied by an unprecedented intensification of economic and financial linkages within geographic regions. The world economy is shifting towards greater regional economic integration. As open and dynamic economies, New Zealand and China heavily rely on international trade and investment to stimulate economic growth. Strengthened international linkages and improved access to markets are major economic strategies for both countries. As they have been committed to building up longstanding and healthy bilateral trade and economic partnerships, these two countries signed a free trade agreement (FTA) that aims to liberalize and facilitate trade in goods, services and investment, and improve the business environment and strengthen cooperation in a wide range of economic areas. From the perspective of New Zealand's businesses, the FTA will not only improve the business environment, and open up market access opportunities, but it will also pose threats. To take advantage of these opportunities, neutralize threats, and consequently achieve a stronger market position in the Chinese marketplace, New Zealand's businesses must strategically respond to the fast-changing environment arising from the FTA. Due to the special meaning of the FTA to New Zealand's economic growth and the significance of the Chinese market to New Zealand's businesses operating in China, it is important to explore how New Zealand's firms perceive the New Zealand-China FTA; and what strategic decisions and adjustments they have made or they are going to make in response to shifts in the business environment arising from the FTA. Besides several studies with limited empirical evidence were conducted at the macro-economic level by some of interested groups such as New Zealand Ministry of Foreign Affairs and Trade during the FTA negotiations, little research has been conducted to examine the impact of the New Zealand-China FTA on New Zealand individual companies' business strategic performance. Building on case studies of two representative companies in the New Zealand natural health products industry, this study aims to discover the nature of salient companies under the New Zealand-China FTA and to ascertain what particular patterns of strategy and performance these companies will adopt in response to trade liberalization. The findings of this study suggest that: 1) With the New Zealand-China FTA, the Chinese fast-growing market is typical of the mix of the opportunities and challenges facing New Zealand's businesses. The FTA provides them with a strong incentive to undertake strategic adjustments for further development in the Chinese market. 2) Strategic adjustments made by a firm depend upon the nature of its firm-specific advantages and country-specific advantages, as well as its existing competitive advantages. Firms that are able to secure their resources and capabilities necessary to exploit opportunities and counter threats are more likely to gain international competitive advantages; 3) Small firms with limited resources and capabilities are more likely to engage in the formation of strategic alliances in order to strengthen their competitive positions both domestically and internationally.</p>

The Awareness and Attitudes of the Public toward Complementary and Alternative Treatments

Introduction: Complementary and alternative medicine (CAM) is flourishing very fast and the usage of CAM in health care is quickly evolving. The behavior and attitude of the patients towards herbal medicines represents an important concern for policy makers and for regulators. Objective: The aim of this study is to evaluate the pattern of natural products use among the public and the Attitudes towards natural health products in Al-kharj Methodology: This is a cross-sectional study design. A questionnaire was prepared using Google drive tool and used to evaluate the pattern of natural products use among the public and the attitudes towards natural health products in Al-kharj governorate. The survey was filled by 442 participants. Results: Most respondents used a natural health product in the past (only 319 of 442 have been used natural product), the most used products were Vitamins/Minerals (85.57%). Additionally, about 50 % of the respondents agreed that the natural health products are safe because they are made from natural ingredients. The majority of the respondents reported that there isn't enough information on natural health product labels to help them understand the Products. The majority reported that the family and friends were recommended and provided them with the information regarding the use of the natural health product (71.78%). Conclusion: The present study showed that the use of herbal medicine is a common practice. The legislation is recommended to arrange the using of natural health products. The study results would surely require an active role for the Ministry of Health and Saudi Food and Drug Authority (SFDA) to insure enough information regard the risks and benefits of NHPs.

Soybean Seed Compounds as Natural Health Protectors

Glycine max (L) Merrill, better known as soy or soybean, is a legume of asian origin considered an excellent biotype, given the fact that it contains almost everything the human being needs for the diet. Its cultivation worldwide is one of the most important, and soy itself and its derivatives are highly on demand. The health effects of soy derived foods have been investigated for more than 25 years, and some of them remain controversial. On the other hand, we wondered if soy could be used to ameliorate the toxic effects of heavy metals. Therefore, in this chapter we review general characteristics of soy as well as its nutritional potential, and we compiled the newest information about the health effects of soy. In order to test our hypothesis, we developed a model of animals exposed to cadmium, and we gave them a soy based diet, comparing it with a casein-based diet as control. This allowed us to collect information about its effect on the respiratory and nervous system. Among the results of this review, we show that it reduces the cholesterol level and obesity while also having antidiabetic effects. We enumerate the benefits of soy-based diets on the respiratory system, such as protection against lung cancer and radiotherapy, better lung function in asthma patients and protection against cadmium intoxication. In the cardiovascular system it reduces the risk of coronary heart disease, improves blood pressure, glycemic control, and inflammation while it reduces not all but some of the alterations induced by cadmium exposure on the aorta and heart. It apparently promotes neurogenesis, improves cognitive functions, and reduces the oxidative stress and apoptosis induced by cadmium exposure in the cerebellum. Taken all together, this information let us conclude that soy consumption would exhibit numerous benefits for human health, although future studies should try to elucidate the best outcome considering variables such as gender, age, treatment duration and dosage of soy products consumption in the diet.

Preliminary assessment of the conservation status of medicinal plant species in Canada

Natural health products in North America are a 9.6 billion US dollar industry that has seen increased demands particularly in products for immune support and anti-viral supplements in response to the Covid-19 pandemic. It has been estimated that ≈40% of the plant raw materials used in natural health products are wild-harvested each year but exact data is missing for many species. Our data show that there are at least 1445 medicinal plant species harvested for commercial products in Canada and 1217 of these are native species. Medicinal plants and non-timber forest crops are also increasingly impacted by climate change as suitable growing areas migrate. In order to ensure long term species survival in the wild, it is necessary to generate accurate information about distribution of wild populations, need for conservation and sustainable method development. Our objective was to provide a preliminary assessment on the conservation status of Canadian medicinal plants by analysis of the available data resources.
