Received: 22 April 2022;  Published: 11 July 2022;  doi: 10.21926/obm.icm.2203026

Abstract

The application of targeted therapies (TT) in oncology has prolonged survivals and even enabled complete remission of cancers previously considered incurable. With small therapeutic indices, the reduction in dosage or spacing out of the doses of TT due to side effects, represents a significant loss of treatment opportunity for the patients. In the absence of drug interaction and significant side effects, homeopathy used in supportive care improves the quality of life of patients, compliance with oncological treatme [...]

The Potential Role of Commensal Microbes in Optimizing Nutrition Care Delivery and Nutrient Metabolism

Received: 20 December 2021;  Published: 26 May 2022;  doi: 10.21926/rpn.2202014

Abstract

Microbes have been part of the diet throughout human history. In the evolution of food preservation practices, some techniques inadvertently leveraged microbial activity not only to extend the storage life but also to enhance the properties and nutritive value of foods. In the last century, a variety of bacterial species (referred to as probiotics) were found to confer health benefits to the host. The advent of high-throughput sequencing methods facilitated improved surveillance of conventional probiotics within gu [...]

Analysis of Correlations for the Prediction of the Entrainment Fraction of Droplets in Gas-liquid Annular Flows

Received: 14 February 2022;  Published: 24 May 2022;  doi: 10.21926/jept.2202019

Abstract

In gas-liquid flows, droplets that detach from the liquid film lining the internal walls of a pipe and merge with the gas flowing through the pipe follow an annular flow pattern. This work analyzes correlations for estimating the entrainment fraction of such droplets contained in the literature by comparing their predictions with experimental data also from the literature. The results of this comparative study demonstrate that the analyzed correlations do not accurately reproduce experimental conditions. This is du [...]

Non-Woven Tissues as Novel Cosmetic Carriers for a Green Beauty

Received: 16 March 2022;  Published: 23 May 2022;  doi: 10.21926/aeer.2202021

Abstract

Approximately 75% of textile waste is generated annually worldwide, as there is a dearth of viable recycling strategies. It has been estimated that textile industries can be responsible for approximately 20% of global water pollution. As a consequence, if not properly managed, the cost of waste management of textile waste will be trillions of dollars annually. Moreover, the generated wastes are detrimental to the environment and public health. On the other hand, there is a possibility that the majority of the waste [...]

Role of Point of Zero Charge in the Adsorption of Cationic Textile Dye on Standard Biochars from Aqueous Solutions: Selection Criteria and Performance Assessment

Received: 19 April 2022;  Published: 19 May 2022;  doi: 10.21926/rpm.2202010

Abstract

The point of zero charge (PZC) is an inherent electrokinetic property of biochars (BC). It influences the adsorption process under certain pH conditions. Herein, we report the method of determination of the PZC values of ten standard BCs. We used the salt addition method to select the BCs with suitable properties for methylene blue (MB) removal from aqueous solutions. The standard BCs were obtained by pyrolyzing five different biomasses at two distinct temperatures (550°C and 700°C). The BCs derived from rice husk [...]

Omega-3 Long-Chain Polyunsaturated Fatty Acids in the Elderly: A Review

Received: 28 February 2022;  Published: 19 May 2022;  doi: 10.21926/obm.geriatr.2202198

Abstract

The omega-3 long-chain polyunsaturated fatty acids (omega-3 LC-PUFAs) family includes eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), and docosapentaenoic acid (DPA). Although seafood is the richest source of omega-3 LC-PUFAs, because diet alone is often insufficient in older people, they may require food supplements and enriched food as sources of omega-3 LC-PUFAs. It has been reported that long-term intake of 3-5 g/d EPA + DHA as supplements is safe for adults; omega-3 LC-PUFAs exert cardio-metabolic pro [...]

A Case Study on the Development of Math Competence in an Eight-year-old Child with Dyscalculia: Shared Intentionality in Human-Computer Interaction for Online Treatment Via Subitizing

Received: 24 January 2022;  Published: 18 May 2022;  doi: 10.21926/obm.neurobiol.2202122

Abstract

Studies in the field of neuroscience have shown that the neural network responsible for numeracy overlaps with the visual and spatial processing regions. Other studies in psychology also highlighted an association of visual-spatial processing with mathematical competence at the early stages of development. These findings suggest that research on the size of the focal area of attention (consciousness) can contribute to understanding the development of numeracy. In this case study, we verified the hypothesis of devel [...]

Visible-Light-Induced Formation of Aromatic Ketones: A Metal-Free C−H Oxygenation Process in Air under Room Temperature

Received: 01 April 2022;  Published: 10 May 2022;  doi: 10.21926/cr.2202014

Abstract

The process of light-induced C-H oxygenation is of high interest as it can be used for the construction of oxygenated compounds. Herein, we report a mild and general method for the efficient synthesis of aromatic ketones following the process of metal-free C-H oxygenation. With air as the oxidant, high functional tolerance was demonstrated, and the desired ketones were obtained in moderate to excellent yields at room temperature (25 oC). Mechanistic studies suggested that the oxidative transformation potentially oc [...]

Lipases: Sources of Acquisition, Ways of Production, and Recent Applications

Received: 16 February 2022;  Published: 07 May 2022;  doi: 10.21926/cr.2202013

Abstract

Enzymes are extensively used in biotechnological processes in several areas of industry. They are sustainable and safe, and their specificity is another characteristic that improves the performance in the process. Among enzymes, lipase is relevant due to the ability to play different roles in the industry and the possibility of collecting them from microbial sources that are found in industrial residues. This can reduce the costs of enzyme production. In relation to that, lipase immobilization is an interesting pro [...]

Integrating Mindfulness Practice in Cognitive Behavioral Hypnotic Psychotherapy

Received: 28 January 2022;  Published: 06 May 2022;  doi: 10.21926/obm.icm.2202021

Abstract

After the emergence of Mindfulness in the Western world, many studies proved its mental and physical benefits. However, implementing Mindfulness in psychotherapy has several challenges: therapists are not formal Mindfulness instructors; the Mindfulness course is a continuous eight-week course, which many patients do not attend during therapy, while others attend and drop out. Thus, Hypnosis was applied to shorten and strengthen the desired changes. The article describes the logic behind this integration, demonstrat [...]

A Large Eddy Simulation Study of Cyclones: The Effects of Interparticle Collisions on Erosion Prediction

Received: 31 January 2022;  Published: 06 May 2022;  doi: 10.21926/jept.2202017

Abstract

Cyclone separators are widely used in fluid catalytic cracking (FCC) units due to their lack of moving parts and relatively low-pressure drop. However, cyclone separators are prone to erosion-related issues, which is a major drawback. In this paper, a large eddy simulation (LES) of the particle-gas flow in a cyclone separator is investigated using a four-way Euler-Lagrange approach to model inter-particle collisions and the exchange of momentum between particles and fluid. The effects of inter-particle and particle [...]
