Trimethylamine N-Oxide as a Potential Risk Factor for Non-communicable
Diseases: A Systematic Review
Authors: Hoseini-Tavassol Zahra , Ejtahed Hanieh-Sadat , Larijani Bagher , Hasani-Ranjbar Shirin
Published: November 2022

Background:

Trimethylamine N-Oxide (TMAO), as a gut microbiota-derived metabolite,
has been associated with a number of chronic diseases like cardiovascular diseases.

Objective:

Considering the increasing prevalence of non-communicable diseases (NCDs), we conducted
a systematic review to discuss the TMAO association with NCDs.

Methods:

A comprehensive search has been conducted on PubMed, Web of Science, and Scopus
databases up to December, 2020. The inclusion criteria were all related observational studies that
surveyed the association between TMAO levels and non-communicable diseases. Interventional
studies, animal experiments, reviews, case reports, letters, congress abstracts, and studies that were
not published in English were excluded. Moreover, related review studies were separately discussed.

Results:

Within 2191 recorded studies, 99 cross-sectional, case-control and cohort studies met the
inclusion criteria. The most common diseases associated with TMAO levels are cardiovascular
diseases, diabetes, kidney disease, stroke, inflammatory diseases, neurological disorders, and
cancer. Elevated TMAO levels as a consequence of alteration in gut microbiota composition and
dietary intake can lead to the incidence of NCDs. The high levels of TMAO can disrupt the homeostasis
of glucose and lipids and induce inflammation that leads to serious NCDs.

Conclusion:

There is a dose-response relationship between TMAO levels and NCDs progression.
Therefore, it can be studied as a therapeutic target or prognostic biomarker for dealing with NCDs.
The Treatment of Parkinson’s Disease with Sodium Oxybate
Authors: Mamelak Mortimer
Published: November 2022

Sodiun Oxybate (SO) has a number of attributes that may mitigate the metabolic stress on
the substantia nigra pars compacta (SNpc) dopaminergic (DA) neurons in Parkinson’s disease (PD).
These neurons function at the borderline of energy sufficiency. SO is metabolized to succinate and
supplies energy to the cell by generating ATP. SO is a GABAB agonist and, as such, also arrests the
high energy requiring calcium pace-making activity of these neurons. In addition, blocking calcium
entry impedes the synaptic release and subsequent neurotransmission of aggregated synuclein species.
As DA neurons degenerate, a homeostatic failure exposes these neurons to glutamate excitotoxicity,
which in turn accelerates the damage. SO inhibits the neuronal release of glutamate and blocks its
agonistic actions. Most important, SO generates NADPH, the cell’s major antioxidant cofactor. Excessive
free radical production within DA neurons and even more so within activated microglia are early
and key features of the degenerative process that are present long before the onset of motor symptoms.
NADPH maintains cell glutathione levels and alleviates oxidative stress and its toxic consequences.
SO, a histone deacetylase inhibitor also suppresses the expression of microglial NADPH oxidase, the
major source of free radicals in Parkinson brain. The acute clinical use of SO at night has been shown
to reduce daytime sleepiness and fatigue in patients with PD. With long-term use, its capacity to supply
energy to DA neurons, impede synuclein transmission, block excitotoxicity and maintain an anti-oxidative
redox environment throughout the night may delay the onset of PD and slow its progress.

Published: November 2022

Palm oil is the most produced and used vegetable oil in the world. The palm oil extraction process is complex and has critical points that, in the event of machinery mismatches or physical process conditions, such as changing temperature, can cause oil losses above the established limit, leading to efficiency and financial losses. Thus, it is necessary to verify the oil content in the residues at each critical point of the process. The method traditionally employed is the solvent extraction (or Soxhlet) procedure (ISO734-1) which is destructive, operator dependent and time consuming, limiting the amount of analysis performed during the process, preventing efficient control and adjustments to correct eventual deviations in each manufacturing stage. The present work aims to present a case study demonstrating the impact on loss reduction after implementing the time domain nuclear magnetic resonance (TD-NMR) technique carried out in April 2021, for the analysis of the oil content in residues from the process of an extractor, following the AOCS Ak 3-94 methodology, replacing the Soxhlet method. The analysis by TD-NMR was performed every hour, going from 336 to 2056 analysis per month, and specific adjustments in each step of the process whenever there was an increase in the percentage of oil in the respective waste in real time. Total annual losses were reduced from 1.64% in 2020 to 1.32% in 2021 (April to December), from an extraction rate of 21.73% in 2020 to 22.78% in 2021 (April to December). The company presented payback of the investment in 2 months. The results demonstrate the great potential of TD-RMN technology in efficient and fast control of losses in the palm oil extraction process with the additional advantages of being a non-destructive method, without the use of toxic reagents, of easy operation and without the need for complex laboratory prompts.
Clean label food protection strategies: Dual functional and synergistic food preservation system with DuraShieldTM natural food protection blends
Authors:   Kalsec Inc., Lee Andrew , Nair Divek
Published: November 2022

Oxidation and microbial spoilage are two major factors that limit the shelf-life of food products. The oxidative reaction results in off aroma, off flavor, and product discoloration in certain instances while microbial spoilage leads to objectionable by-product formation, visible microbial growth, and potential food safety risks. Temperature variations, extended distances of distribution, and demand for cleaner labels have all contributed to an increased risk of food spoilage in both minimally processed and ready-to-eat products. DuraShield Food Protection Blends are scientifically proven to be effective in improving shelf life and safety by combining traditional antioxidant products (including rosemary extracts and acerola) with natural cultured dextrose and/or buffered vinegar and leveraging their dual-functional and synergistic properties. They deliver minimal impact on taste and aroma and, in most cases, help to maintain a cleaner, consumer-preferred label. The proposed session will demonstrate the dual-functional and synergistic aspects of DuraShield Food Protection blends that will help to tackle complicated spoilage issues in variety of food products.

Sophorolipid is a glycolipid-type biosurfactant, produced from natural sources by fermentation with a nonpathogenic yeast Starmerella bombicola. Its structure is composed of 2 hydrophilic parts, a sophorose unit, a glucose disaccharide glycosically linked to a hydroxyl fatty acid. Its structure spontaneously forms a vesicle of about 100 nm in an aqueous solution, which is similar to that of liposomes used as drug delivery systems and transdermal absorption promoters. It can be expected to have an effect of promoting permeation of active substances such as lactoferrin. Lactoferrin is an iron-binding glycoprotein having a molecular weight of about 80 kDa, and is most abundant in breast milk in the living body. Since it is also present in amniotic fluid that protects the mother and fetus, it is important to study the physiological relationship between skin and lactoferrin. The transdermal administration of lactoferrin with sophorolipid was verified, followed by the investigation protein-surfactant interactions between bovine lactoferrin and sophorolipid. Structural changes were further observed using spectroscopic, microscopic and biochemical methods under weakly acidic and neutral pH conditions. From particle size analysis by dynamic light scattering, microscopic observation by cryo-SEM, and digestion pattern observation by enzyme treatment, it was confirmed that bovine lactoferrin and sophorolipid interact with each other to form a sheet and nanometer-sized coagulation at pH 5.0 and 7.0 forming an aggregate, which was considered to be due to the self-organizing structure characteristic of sophorolipid. It can be concluded that sophorolipid has a potential of being a transport carrier of active substances, which can have vast applications not only in cosmetics but in drug delivery systems as well.

Life cycle assessment (LCA) of microbial oil-derived fuels and other non-fuel products
Authors:   Farmsow Pvt. Ltd., Khot Mahesh Balwant
Published: November 2022

Much literature is available on fungal lipids and their capability as a renewable oil platform for alternate fuels, chemicals, and food products. Microbial oils will not displace all edible oils soon, given techno-economical hurdles in commercialization. However, continued research & development can flatten the curve of deforestation and land-use impacts associated with cultivating these crops. To better understand how oleaginous yeasts and fungi could alleviate the challenges related to the energy-environment-food nexus, it becomes critical to investigate their potential environmental impacts quantitively compared to other feedstocks. Life cycle analysis or assessment (LCA) is a standard tool used for this purpose. LCA studies are not being conducted on a broader scale for fungus-derived oils than their phototrophic algal counterparts. The different stages in the life cycle of fungal lipid production that can be analyzed for environmental implications include cultivation and fermentation, oil extraction; further downstream processing; and end-use. The LCA method for fungal lipid-derived biofuel production systems should cover the main sustainability concerns of biofuel production systems: energy efficiency, climate change, and land occupation. With the scope of microbial oil applications expanding beyond non-fuel encompassing food, supplements, and medicines, their subsequent environmental implications need to be investigated. Further work is required in this area. There are significant knowledge gaps in life cycle inventory and impact assessment information for non-fuel applications.
Recent analytical methodologies for the determination of MOSH/MOAH in edible oils & fats
Authors:   Institut Kirchhoff Berlin GmbH part of Mérieux NutriSciences, Kuhn Susanne , Koch Michael
Published: November 2022

As an undissolved complex mixture, petroleum hydrocarbons pose a special challenge not only to toxicologists. Since this contaminant was first detected to migrate from cardboard packaging into foods in 1995, toxicological knowledge, methodology and awareness of petroleum sources have evolved. Likewise, the requirements for an analytical method in-creased. The risks of aromatic petroleum hydrocarbons (MOAHs), and in particular 3-7 ring MOAHs, has been increasingly emphasized by EFSA. Edible oils and fats are among the foods at high risk for mineral oil contamination. They are also one of the most difficult matrices. Typical interference from squalene, carotenoids, and other terpenic structures must be re-moved prior to quantification of MOAH by LC-GC-FID. Epoxidation, as the method of choice, is a crucial step in the removal of these biogenic interferences. This sample preparation step has recently been revised and improved. During the talk, the latest improvements of the epoxidation procedure will be presented with examples from a service laboratory. Furthermore, the advantages of GCxGC technology to evaluate the toxicological relevance of the MOAH fraction will be addressed.
Production of value-added oleochemicals via Eversa immobilized lipase-catalyzed esterification
Authors:   Korea University, Kim In-Hwan , Oh Dongchan , Choi Suhyeon
Published: November 2022

Eversa lipase (from Themomyces lanuginosus) as a liquid type was developed to produce biodiesel. In our previous study, diisononyl adipate was effectively synthesized with an immobilized lipase prepared from Eversa lipase using Lewatit VP OC 1600 as a carrier. In this study, two oleochemicals, palmitoleic acid rich triacylglycerol (TAG) and 2-ethylhexyl palmitate, were successfully synthesized by Eversa immobilized lipase-catalyzed esterification. The palmitoleic acid rich TAG was synthesized from macadamia nut oil via two-step enzymatic reactions, which are C. rugosa lipase-catalyzed hydrolysis and Eversa immobilized lipase-catalyzed esterification. 2-Ethylhexyl palmitate, which is widely used as a cosmetic ingredient, was synthesized from 2-ethylhexanol and palmitic acid in a solvent-free system via Eversa immobilized lipase-catalyzed esterification. In both studies, Eversa immobilized lipase exhibited significantly higher activity for the synthesis of 2-ethylhexyl palmitate than Novozym 435, which is known as a commercial lipase with substantially high activity for esterification. In addition, Eversa immobilized lipase exhibited similar activity for the synthesis of palmitoleic acid rich TAG compared to the Novozym 435.
Antioxidant and antimicrobial active packaging systems

Published: November 2022

The shelf life of foods is mostly limited by microbial growth and oxidation reactions. Reducing both these mechanisms by active packaging is an attractive concept to enhance the shelf life. Antimicrobial packages recently developed combine natural antimicrobial compounds like carvacrol and isothiocyanates with biobased polylactic acid (PLA) films. Antioxidant packaging can be used to further improve product quality and extend the shelf life of food by free radical scavenging. As an example, a radical scavenger and singlet oxygen quencher, b-carotene, was incorporated into PLA to develop an antioxidant film. The usage of sunflower oil based oleogel as lipid food model was chosen to focus on the lipid oxidation process. We studied the antioxidant activity and color/thermal properties of the antioxidant loaded PLA film. Preliminary results show that the thermal stability of films was not affected by b-carotene addition. b-carotene significantly improved the antioxidant properties of the films in both DPPH and ABTS radical-scavenging activity tests. We evaluated the oxidation stability of sunflower oil based oleogels as a model food product prepared with different proportions of stearic acid (SA) and hydroxypropyl methylcellulose (HPMC). The difference between direct and indirect contact between the product and the film was determined. Preliminary results show that b-carotene-loaded PLA film was able to inhibit lipid oxidation, reducing the formation of lipid hydroperoxides and TBARS of the resulting oleogels. Further research will be on combining the antioxidant and antimicrobial activity of packaging films to further enhance the shelf life of products vulnerable to oxidation and microbial spoilage.
Novel and Versatile Tool for Investigating the Oxidation Stability of Speciality Oils
Authors:   ANTON PAAR PROVETEC GMBH, Edinger Carolin , Paar Anton
Published: November 2022

The quality of fats, oils, and food products in general strongly depends on their oxidation stability. In this contribution a novel tool for evaluating the oxidation stability of oil and oil containing products is introduced. Under accelerated conditions (elevated temperature and pure oxygen pressure) a sample of 5 mL/4 g is examined in a sealed stainless steel test chamber. Typical conditions of the method are temperatures between 80 °C–140 °C and an initial oxygen pressure of 700 kPa. These conditions initiate a rapid oxidation process, which is monitored by recording the pressure in the test chamber. It was found that oxygen consumption and pressure drop are directly related. This allows the determination of the oxidation stability of the sample and offers further investigation possibilities. Due to the defined oxygen volume in the sealed test chamber, the exact oxygen consumption can be calculated. Beneficially, the oxidation stability of complex food products can be investigated since even solid samples can be measured without prior sample preparation. Application examples demonstrate the broad variety of samples and the effec-tiveness of the method. Screening or investigating the effect of antioxidants, the storage stability of samples, or estimating shelf-life of fats and oils are just some examples. The significantly reduced measurement time and an excellent repeatability of the method are only two of its major ad-vantages, allowing for quick and direct measurement of the oxidation stability for research, process and test bench control.
CoverCress—a novel oilseed winter crop with canola-like composition that helps sequester carbon and prevent soil erosion.
Authors:   CoverCress Inc., Ulmasov Tim
Published: November 2022

There is an urgent need for reducing greenhouse gas emissions and other detrimental impacts of civilization on the environment. One of the solutions proposed in agriculture are cover crops that are generally grown between regular cropping seasons, providing significant benefits such as enhanced soil health and increased carbon sequestration. The main problem with lack of wide-spread cover crops adoption is in their economics, as most farmers avoid them due to guaranteed costs and uncertain returns from the benefits to the following crop. This results in misplaced economic incentive where the society greatly benefits from increased cover crop use, but most farmers are not prepared to pay for that. To address this dilemma, we developed a novel crop that can be used as a feedstock for bioenergy, as well as for human and animal consumption. The main advantage is that it doesn’t compete for land with established crops, resulting in very low Carbon Intensity (CI) score of the oil and meal. It is based on the domesticated version of weed field pennycress (Thlaspi arvense) and can be used to produce oil with attractive properties for renewable diesel, jet fuel or food. CoverCress seeds are also a good source of proteinaceous meal with that can be used for animal feed or plant-based protein for human consumption. Pennycress seeds have high (~32%) oil content with lowest saturated fat content among commercially available plant-based oils (< 4%). The winter annual life cycle of pennycress enables planting in early fall immediately following corn harvest and collecting the grain prior to soybean planting in mid-to-late May. Using a combination of conventional breeding and CRISPR-mediated genome editing we were able to rapidly domesticate wild pennycress into CoverCress, a low CI, canola-like crop that is planned for launch in central Midwest as soon as in fall of 2022.

Seeking some common and desirable values is not only the basic needs of harmonious society, but also the inevitable result of human civilization evolution. Sakya legshad, the 1st collection of Chinese Tibetan aphorisms, and Bacon’s Essays, the Britain prose collection, are the world-wide treasures of wisdom, many chapters of which talk about the concept and practice of goodness. It is of immeasurable importance to reread these classics for interpretations of goodness so that their excellent traditional culture can continue to nourish and enlighten today’s moral education, promote the construction of the common views on the good and the evil, awaken people a moral consciousness, and enlighten them to hold good will and do good deeds for sustainable social harmony and world peace.
Fake Cavaliers of Southern Women: Biblical Allusions in Faulkner’s works—Based on Dry September and The Sound and the Fury
Authors: Yue Wu
Published: November 2022

As a native of the South, Faulkner had a deep love of this land and was also deeply influenced by this land which known as the Biblical Belt. In his novel, The Sound and the Fury and short story Dry September, Faulkner looks back at the changing history of American South and takes an insightful stock of the impact that society had on people at that time. This paper intends to find the parallel correspondence between the Bible and the texts through the deep analysis of each plot, characters and narrative structure. This paper also creatively employs the story of the rape of Dinah in the Bible to analyze the purpose and deep meaning behind men's seemingly righteous revenge for the women of his family. The writer concludes that in patriarchal society, weather in the primitive period of Dinah, or in the modern era of Minnie and Caddy, the purpose of men’s fierce revenge for the contamination of female chastity was to preserve family honor and status, and as for the women’s situation and sufferings were of little importance to them.

The objective of this writing is to clarify the changes that robotic cholecystectomy brought to the patient and its repercussions when compared to conventional laparoscopy. The present study is an integrative literature review that seeks to describe the innovations that this surgery brought to cholecystectomy, performing a search in the Virtual Health Library and PubMED based on the guiding question: "Are there benefits of robotic surgery over the laparoscopic technique in patients undergoing cholecystectomy?", with the descriptors "Robotic Surgical Procedure", Cholecystectomy and Outcomes Study totaling 76 articles at the end, being used 20 for the preparation of the text. It was noticed that robotic surgery has conquered a lot of space in general surgery, aiming to overcome the limits that conventional laparoscopy presents, seeming to provide more satisfactory results. However, because it is a relatively new technique, the little experience on the part of surgeons, together with the high cost, does not seem to be attractive for large centers. Despite this, good aesthetic, technical, and ergonomic results have been found. We conclude that despite a good number of articles on the subject, there is an important lack of concordance among them, which generates the need for new studies approaching the theme in order to help in the elaboration of concrete evidence.

Immersion in rural reality has been a challenge for the Veterinary Medicine at the Federal Rural University of Pernambuco, whose training locus are generally concentrated in classrooms and laboratories. Furthermore, the immersion in the reality of a land reform settlement was even more challenging, as it is a reality that is almost unknown by the students. Additionally, the students had to assume the leading role in the construction of knowledge, based on the methodology of problematization, and it was also a challenging. That is, knowing the phenomena from the concrete reality, which by the way, presented itself in a dynamic, plural and diverse way. And, of course, the experience was something quite new to students traditionally used to listening, receiving and writing down content in a fragmented way and with little room for deepening, dialogue and connection between the knowledge covered. This is because the view of reality in this case is always superficial and partial, as it often boils down to the individual point of view of the teacher and the restricted universe of four walls. And, therefore, knowing reality as it is implies, first of all, immersing in its complexity to know the intricacies and in-between of its parts and the contours of its totality, making it meaningful. Therefore, the methodology of problematization, in the light of the principles and concepts of Agroecology, of the dialogue between traditional knowledge and scientific knowledge, of experience and concrete experience, of dialogue with rural families, of intervention in reality, of reflection-action of the spaces built, in short, of the educational processes carried out, seem to have changed, greatly, not only the practice of the settlers, but above all the way of thinking and doing education of the students and educators involved.

Published: November 2022

Los pacientes con “síntomas físicos médicamente no explicados” (mus, en inglés) son frecuentes en la consulta médica; estos pacientes acuden a consulta por síntomas inespecíficos, de etiología incierta, sin cuadro clínico definido, exploración física normal para su queja y laboratorio e imagen sin anormalidades. El abordaje de un paciente con mus puede ser todo un desafío, provoca frustración en el médico e insatisfacción en los pacientes; implica mayor costo en la atención y saturación de servicios de salud. Hay varias intervenciones no farmacológicas que han mostrado utilidad. El médico familiar debe adquirir destrezas para atender a estos pacientes. En esta revisión se describen las etapas ordenadas para el abordaje de pacientes con mus como:

1. ¿Qué hacer? Trabajar sobre la reatribución del síntoma. Establecer conexión: entre evento estresante y síntoma(s) inespecífico(s). 2. ¿Cómo hacerlo?

Relación entre la creación de valor económico y la insolvencia financiera en empresas no cotizantes en el mercado de valores de Colombia (2016-2019)
Authors: Isaac Roque Daniel , Caicedo Carrero Andrés
Published: November 2022

Este artículo tiene como objetivo evaluar la correlación que presentan los resultados de las herramientasfinancieras Altman Z-Score y el Economic Value Added (EVA). Para lograr este propósito se aplica un enfoque metodológico cuantitativo, con un alcance descriptivo. Los resultados corroboran la efectividad de la aplicación individual del EVA y el modelo de puntaje Z. Sin embargo, las pruebas estadísticas (correlación, gráfica de dispersión y regresión lineal) revelan una baja relación entre la creación de valor económico agregado y la probabilidad de insolvencia financiera. Los hallazgos evidencian que, al aplicar las dos herramientas de medición de desempeño financiero, los resultados se pueden contradecir entre sí la empresa crea valor, que implica que tiene una baja probabilidad de insolvencia financiera, y la probabilidad de quiebra, es decir, un Z-Score bajo. Se puede concluir que la baja relación se debe a la base de información financiera que se utiliza para el cálculo de ambas herramientas. A diferencia de la aplicación del EVA, que necesita definir variables exógenas que las empresas no pueden controlar, el modelo Z centra su cálculo en variables endógenas de los estados financieros de la empresa.

The case for earnings management has often been made by companies that aim to improve company performance. The concept of Good Corporate Governance is applied to reduce various risks in earnings management, therefore, this study aims to empirically test whether there is an effect of profitability leverage and free cash flow on earnings management, as well as whether good corporate governance approached by self-assessment can moderate the effect of leverage, profitability, and free cash flow on earnings management in state-owned enterprises. The data used is secondary data from the Indonesian stock exchange and the company’s website. The population of this study is stateowned companies listed on the Indonesian Stock Exchange in 2013-2019. The data analysis technique used moderated regression analysis. The results showed that leverage and free cash flow influenced earnings management, while profitability has no effect on earnings management and self-assessment can moderate the effect of leverage on management and self-assessment cannot moderate the effect of profitability and free cash flow on earnings management.

O contexto escolar é múltiplo e dinâmico, pois nele estão inseridos diferentes atores que se inter-relacionam. Relações permeadas por um conjunto de regras estabelecidas cujo não cumprimento, pode ser entendido como indisciplina escolar. A presente investigação teve como objetivo analisar percepções de um grupo de professores, de uma escola pública mato-grossense, sobre a gravidade da indisciplina escolar e como lidar com ela. Trata-se de uma pesquisa de natureza básica, de abordagem quantitativa, ocorrida nos últimos meses de 2019. Ao todo, participaram da pesquisa 17 professores de uma escola estadual do município de Vila Rica/MT. Os dados foram coletados por meio de um questionário contendo 10 (dez) questões fechadas, cujos resultados foram tabulados em gráficos e discutidos com base no referencial teórico. Cada questão era referente a algum aspecto da conduta do estudante relacionado com a indisciplina escolar. Para avaliar tais aspectos, foram utilizadas quatro escalas de gravidade: nada grave, pouco grave, grave e muito grave. Pelos resultados analisados é possível inferir que os professores consideram como casos mais graves de indisciplina do comportamento estudantil: incentivar os colegas ao mau comportamento e insultar ou ameaçar o(a) professor (a). Por outro lado, atos de conversar com os colegas, interromper explicações do professor ou divergir do que ele falou não são considerados, pela maioria dos professores, comportamentos indisciplinados. Após a análise dos dados, torna-se possível considerar que, para os(as) professores(as), as discussões sobre indisciplina escolar proporcionam reflexões importantes acerca desse fenômeno, possibilitando a esses atores sua compreensão e possivelmente, subsídios para minimizar seus impactos na aprendizagem dos estudantes.
