[PMID: 39802095 PMCID: PMC11719331 DOI: 10.1016/j.bjao.2024.100360] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/11/2024] [Accepted: 11/10/2024] [Indexed: 01/16/2025]
Abstract
Requests for medical and anaesthetic care that is 'vegan' or free of animal-derived components are becoming increasingly common in the cultural landscape. Such requests are often rooted in religious beliefs and practices. There are currently no requirements for the disclosure of animal-derived components in medical items. However, both patients and medical professionals agree that greater transparency regarding such items is needed in obtaining informed consent. Although the ethical argument for disclosure has been established, there remain gaps in practical guidelines in recognising animal-derived components in medical items and understanding how to avoid them. This lack of comprehensive knowledge leads to challenges in initiating conversations about appropriate medication selection. This manuscript will outline the common dietary restrictions of various religious groups and provide instruction on common animal-derived ingredients in medications. It will also introduce potential viable animal-free alternatives for some commonly used medications in the perioperative environment which has not been done previously in the literature. Moreover, we note the broader implications and reasoning behind considering dietary restrictions in medication choices.

JOURNAL OF THE SCIENCE OF FOOD AND AGRICULTURE 2024.

Abstract
Increasing global palm oil production yields a valuable palm fatty acid distillate (PFAD) - a rich vitamin E (Vit-E) source and multifunctional ingredient in the food agro-industry - that can be utilized to achieve sustainability. This article reviews trends in the use and role of PFAD and its Vit-E in the food sector and proposes an integrated agro-industrial concept toward sustainability. Vit-E can be separated from PFAD with diverse and impactful pharmaceutical activities, including antioxidant, anti-inflammatory, anticancer and anti-ultraviolet effects. Based on in vivo experimental tests, PFAD and Vit-E supplementation can enhance the productivity and quality of livestock-based food products. PFAD is a plasticizer and antistatic packaging material in food packaging systems, and its derivatives can be used as food additives. Meanwhile, the Vit-E molecule in packaging can extend food shelf life by maintaining color stability, reducing lipid oxidation and rancidity, adding antimicrobial properties, and influencing changes in packaging properties such as water vapor, tensile strength, melting point and other physical properties. Toward sustainability, an integrated agro-industrial design has been proposed to implement clean production, increase the added value of palm oil industry residues, minimize environmental risks and increase profits to achieve long-term social welfare. In conclusion, PFAD residues and their Vit-E content have shown broad benefits in the food sector and prospects toward sustainability. © 2024 Society of Chemical Industry.

Abstract
Surfactants are a diverse group of compounds that share the capacity to adsorb at the boundary between distinct phases of matter. They are used as pharmaceutical excipients, food additives, emulsifiers in cosmetics, and as household/industrial detergents. This review outlines the interaction of surfactant-type excipients present in oral pharmaceutical dosage forms with the intestinal epithelium of the gastrointestinal (GI) tract. Many surfactants permitted for human consumption in oral products reduce intestinal epithelial cell viability in vitro and alter barrier integrity in epithelial cell monolayers, isolated GI tissue mucosae, and in animal models. This suggests a degree of mis-match for predicting safety issues in humans from such models. Recent controversial preclinical research also infers that some widely used emulsifiers used in oral products may be linked to ulcerative colitis, some metabolic disorders, and cancers. We review a wide range of surfactant excipients in oral dosage forms regarding their interactions with the GI tract. Safety data is reviewed across in vitro, ex vivo, pre-clinical animal, and human studies. The factors that may mitigate against some of the potentially abrasive effects of surfactants on GI epithelia observed in pre-clinical studies are summarised. We conclude with a perspective on the overall safety of surfactants in oral pharmaceutical dosage forms, which has relevance for delivery system development.

Abstract
STAT3 signaling is a major intrinsic pathway for cell proliferation owing to its frequent activation in injured tissues. Various STAT3-regulated genes encode cytokines and growth factors, the receptors of which in turn activate the same STAT3 pathways, thereby regulating cell proliferation. In present study, we aimed to analyze several compounds for their wound healing and tissue repair potential by computer-aided virtual screening and Molecular dynamics (MD) simulation. Based on literature studies, a total of 36 drug molecules were selected having critical functions in wound healing and tissue repair. The pharmacological features (ADME and toxicity) of these molecules were predicted to find lead molecules among them. Further, a comparative study was performed to screen binding efficiency of STAT3 with many conventional wound healers by molecular docking. Among all, W6S, Strychnin, Prednisone and N-(6-(4-(3-(4-((4-Methylpiperazin-1-yl) methyl)-3- (trifluoromethyl)phenyl)ureido)phenoxy)pyrimidin-4-yl)cyclopropanecarboxamide showed best docking with STAT3 protein. The calculated binding energy of these molecules with STAT3 was found to be -8.9 Kca/mol for N-(6-(4-(3-(4-((4-Methylpiperazin-1-yl) methyl)-3-(trifluoromethyl) phenyl)ureido)phenoxy)pyrimidin-4-yl)cyclopropanecarboxamide, -8.7 Kcal/mol for W6S, -8.5 Kcal/mol for Strychnine and -8.4 Kcal/mol for Prednisone . The result was reconsidered for MD simulation. The simulation result showed stable binding of the ligand with STAT3 protein for 100 ns. These compounds showed better interaction potential with STAT3 was compared to known tissue repair molecules. Our data paves way for further exploration of these molecules as novel cell proliferators to be tested in various types of wound and tissue injuries.Communicated by Ramaswamy H. Sarma.

Abstract
The fragility of biological systems during storage, transport, and utilization necessitates reliable cold-chain infrastructure and limits the potential of biotechnological applications. In order to unlock the broad applications of existing and emerging biological technologies, we report the development of a novel solid-state storage platform for complex biologics. The resulting solid-state biologics (SSB) platform meets four key requirements: facile rehydration of solid materials, activation of biochemical activity, ability to support complex downstream applications and functionalities, and compatibility for deployment in a variety of reaction formats and environments. As a model system of biochemical complexity, we utilized crudeEscherichia colicell extracts that retain active cellular metabolism and support robust levels of in vitro transcription and translation. We demonstrate broad versatility and utility of SSB through proof-of-concepts for on-demand in vitro biomanufacturing of proteins at a milliliter scale, the activation of downstream CRISPR activity, as well as deployment on paper-based devices. SSBs unlock a breadth of applications in biomanufacturing, discovery, diagnostics, and education in resource-limited environments on Earth and in space.

Abstract
Manganese (Mn) is an essential element for humans and animals including, fish. It is a still poorly studied in aquatic organisms, where it can be noticeably useful for dietary components and also found pollutant in aquatic environment at high concentrations. On the above information, an experiment was delineated to determine the lethal concentration of manganese (Mn) and manganese nanoparticles (Mn-NPs) alone and with high temperature (34 °C) and its effect on various biochemical markers in Pangasianodon hypophthalmus. The median lethal concentration (96-LC50) of Mn alone (111.75 mg L-1) and along with high temperature (110.76 mg L-1), Mn-NPs alone (93.81 mg L-1) and with high temperature (34 °C) (92.39 mg L-1) was determined in P. hypophthalmus. The length and weight of the fish were 6.32 ± 0.23 cm and 7.57 ± 1.35 g. The present investigation used five hundred forty-six fish, including range finding (216 fish) and definitive test (330 fish). The acute definitive doses were applied to assess the effect of oxidative stress, glycolytic biomarkers, protein biomarkers, fish immunity, neurotransmitter, energy level, stress hormone and histopathology. Oxidative stress (catalase, superoxide dismutase, glutathione-s-transferase and glutathione peroxidase), stress biomarkers (lipid peroxidation, cortisol, heat shock protein, and blood glucose), lactate and malate dehydrogenase, alanine and aspartate aminotransferase, a neurotransmitter, glucose-6-phosphate dehydrogenase (G6PDH), ATPase, immune system biomarkers (NBT, total protein, albumin, globulin and A:G ratio) were altered with exposure to Mn and Mn-NPs. The histopathology of the liver and gill were also changed due to exposure to Mn and Mn-NPs. The bioaccumulation of Mn in the liver, gill, kidney, brain and muscle tissues, and experimental water at different intervals of 24, 48, 72 and 96 h were determined. Based on the present results, it is strongly suggested that Mn and Mn-NPs exposure alone and with high temperature (34 °C) enhanced toxicity and altered biochemical and morphological attributes. This study also suggested that essential elements in both forms (inorganic and nano) at higher concentrations of Mn and Mn-NPs lead to pronounced deleterious alteration in cellular and metabolic activities and histopathology of P. hypophthalmus.

Abstract
SARS-CoV-2 emerged in 2019 and led to the COVID-19 pandemic. Efforts to develop therapeutics against SARS-Cov-2 led to both new treatments and attempts to repurpose existing medications. Here, we provide a narrative review of the xenobiotics and alternative remedies used or proposed to treat COVID-19. Most repositioned xenobiotics have had neither the feared toxicity nor the anticipated efficacy. Repurposed viral replication inhibitors are not efficacious and frequently associated with nausea, vomiting, and diarrhea. Antiviral medications designed specifically against SARS-CoV-2 may prevent progression to severe disease in at-risk individuals and appear to have a wide therapeutic index. Colloidal silver, zinc, and ivermectin have no demonstrated efficacy. Ivermectin has a wide therapeutic index but is not efficacious and acquiring it from veterinary sources poses additional danger. Chloroquine has a narrow therapeutic index and no efficacy. A companion review covers vaccines, monoclonal antibodies, and immunotherapies. Together, these two reviews form an update to our 2020 review.

Biodegradation of Reactive Yellow-145 azo dye using bacterial consortium: A deterministic analysis based on degradable Metabolite, phytotoxicity and genotoxicity study. CHEMOSPHERE 2022; 300:134504. [PMID: 35398073 DOI: 10.1016/j.chemosphere.2022.134504] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/27/2022] [Revised: 03/14/2022] [Accepted: 03/31/2022] [Indexed: 06/14/2023]
Abstract
Azo dyes are used at larger-scale as coloring agent in the textile industry. It generates a huge amount of dye containing wastewater and its toxicity threatens all kinds of life and also impacts human beings. At present, more impetus is being given to the biological treatment of dye effluent because of its azoreductase enzyme action to break down azo bond which leads to decolorization and degradation of dye. Bacterial consortium of E. asburiae and E. cloacae (1:1 ratio) was used for degradation and decolorization of Reactive Yellow-145 (RY-145) dye. The optimization of dye concentration, temperature, pH, and media has been carried out to determine the conditions required for maximum degradation and decolorization. The mixed consortium (10%) has shown 98.78% decolorization of RY-145 dye under static condition at 500 mgL-1 concentration, 35 °C and pH 7.0 at 12 h contact period. FTIR analysis showed formation of new functional groups in the treated dye, such as O-H stretch at 1361 cm-1, C-H stretch at 890 cm-1, N-H stretch at 1598 cm-1 and aromatic C-H at 671 cm-1 revealing degradation of dye. Biodegraded metabolites of RY-145 dye were identified through GC-MS analysis that includes 2-Cyclohexen-1-ol, 5-Nitroso-2, 4, 6-triaminopyrimidine, Octahydroquinoline-9-hydroxyperoxide, Tetramethyl-2-hexadecen-1-ol, 9-Octadecanoic acid, methyl ester and Hexadecanoic acid, methyl ester, respectively which have industrial applications. Cyclohexane was used in gasoline and adhesive while Octahydroquinoline-9-hydroxyperoxide and 5-Nitroso-2, 4, 6-triaminopyrimidine were used in manufacturing drugs. Tetramethyl-2-hexadecen-1-ol, 9-Octadecanoic acid, methyl ester and Hexadecanoic acid, methyl ester are antimicrobial and antioxidant. Phytotoxicity test also showed non-toxic effects of treated dye on germination of Cicer arietinum and Vigna radiata seeds. Similarly, genotoxicity study indicated less toxic effects of biodegraded dye products on Mitotic index (MI) and cell division of Allium cepa.

Abstract
BACKGROUND Naringenin (NAR) is a flavonoid with excellent antioxidant and neuroprotective potential that is limited by its low solubility. Thus, solid dispersions with β-cyclodextrin (β-CD), hydroxypropyl-β-cyclodextrin (HP-β-CD), hydroxypropylmethylcellulose (HPMC), and microenvironmental pH modifiers were prepared. METHODS The systems formation analysis was performed by X-Ray Powder Diffraction (XRPD) and Fourier-transform infrared spectroscopy (FT-IR). Water solubility and dissolution rates were studied with a pH of 1.2 and 6.8. In vitro permeability through the gastrointestinal tract (GIT) and the blood-brain barrier (BBB) was assessed with the parallel artificial membrane permeability assay (PAMPA) assay. The antioxidant activity was studied with the 2,2'-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid (ABTS) and cupric ion reducing antioxidant capacity (CUPRAC) assays, while in vitro enzymes studies involved the inhibition of acetylcholinesterase, butyrylcholinesterase, and tyrosinase. For the most promising system, in silico studies were conducted. RESULTS NAR solubility was increased 458-fold by the solid dispersion NAR:HP-β-CD:NaHCO3 in a mass ratio of 1:3:1. The dissolution rate was elevated from 8.216% to 88.712% in a pH of 1.2 and from 11.644% to 88.843% in a pH of 6.8 (within 3 h). NAR GIT permeability, described as the apparent permeability coefficient, was increased from 2.789 × 10-6 cm s-1 to 2.909 × 10-5 cm s-1 in an acidic pH and from 1.197 × 10-6 cm s-1 to 2.145 × 10-5 cm s-1 in a basic pH. NAR BBB permeability was established as 4.275 × 10-6 cm s-1. The antioxidant activity and enzyme inhibition were also increased. Computational studies confirmed NAR:HP-β-CD inclusion complex formation. CONCLUSIONS A significant improvement in NAR solubility was associated with an increase in its biological activity.

Abstract
Results of genotoxicity studies for magnesium salts of isobutyrate and 2-methylbutyrate, two candidate ingredients for inclusion in animal feed, are described in this manuscript. Both substances were tested for mutagenicity in a bacterial reverse mutation assay and clastogenicity/aneugenicity in an in vitro micronucleus study in human lymphocytes, conducted according to Organisation for Economic Co-operation and Development (OECD) Guidelines. The substances were tested up to the limits of solubility in the tests. The results showed that that magnesium salts of isobutyrate and 2-methylbutyrate are not mutagenic, clastogenic or aneugenic. The tests were valid, as the negative and positive controls produced expected responses.

Abstract
Objective To describe a case of a patient who developed psychosis after ingestion of Vertigoheel for treatment of dizziness. Case Summary A 28-year-old male with no psychiatric history presented with 5 days of worsening depression and psychosis. He denied current use of prescription medications, alcohol, or illicit substances. Approximately 2 weeks prior, while visiting family in Germany, he developed dizziness. A provider in Germany prescribed Vertigoheel, 1 tablet to be taken every hour until symptom improvement. This did not improve his dizziness but did cause him to feel as if he were "in a dream." He stopped taking the medication after 2 days but continued to feel amotivated with decreased appetite and insomnia. Several days later, he developed ego-dystonic auditory hallucinations. He returned to the United States; was admitted to an inpatient psychiatric unit for 4 days; and given olanzapine 5 mg at bedtime, lorazepam 1 mg every evening, and melatonin 6 mg every evening. He experienced gradual improvement in symptoms and was discharged with olanzapine 5 mg daily and outpatient follow-up. Discussion Vertigoheel is a homeopathic preparation containing ambra grisea, Cocculus indicus, Conium maculatum, and petroleum. Psychosis was not reported in any of the randomized controlled trials evaluating the use of Vertigoheel for treatment of vertigo. A literature search revealed no published reports of psychosis as a result of administration of any components of Vertigoheel. Conclusion A possible causal relationship was observed between the homeopathic supplement Vertigoheel and an acute episode of psychosis in a young male patient with no comorbidities.

Oral and Topical Centella asiatica in Type 2 Diabetes Mellitus Patients with Dry Skin: A Three-Arm Prospective Randomized Double-Blind Controlled Trial. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2020; 2020:7253560.

Abstract
Introduction Uncontrolled diabetes mellitus (DM) is related to skin disorders, particularly dry skin. Pathogenesis of dry skin in type 2 diabetes mellitus (T2DM) rises from the chronic hyperglycemia causing an increase in advanced glycation end-products (AGEs), proinflammatory cytokines, and oxidative stress. Combination of oral and topical Centella asiatica (CA) is expected to treat dry skin in T2DM patients more effectively through decreasing N(6)-carboxymethyl-lysine (CML) and interleukin-1α (IL-1α) and increasing superoxide dismutase (SOD) activity. Methods A three-arm prospective, double-blind, randomized, controlled study was performed to evaluate the efficacy of the oral and topical CA extract in 159 T2DM patients with dry skin. The subjects were divided into the CA oral (CAo) 2 × 1.100 mg + CA topical (CAt) 1% ointment group, oral placebo (Plo) + CAt group, and Plo and topical placebo (Plt) group. Dry skin assessment was performed on day 1, 15, and 29, while evaluation of CML, IL-1α, and SOD activity was on day 1 and 29. Result Effectivity of CAo + CAt combination was assessed based on HbA1c and random blood glucose (RBG). In well-controlled blood glucose, on day 29, the percentage of SRRC decrement was greater in the CAo + CAt group compared to the control group (p = 0.04). SCap value in the CAo + CAt group was greater than that in the control group (p = 0.01). In the partially controlled blood glucose, increment of SOD activity in the CAo + CAt group was greater than that in the control group (p = 0.01). There were medium-to-strong correlation between CML with SOD (r = 0.58, p < 0.05) and IL-1α with SOD (r = 0.70, p < 0.05) in well-controlled blood glucose. Systemic and topical adverse events were not significantly different between groups. Conclusion CAo and CAt combination can be used to significantly improve dry skin condition through increasing SOD activity in T2DM patients with controlled blood glucose.

Abstract
Genotoxic assay via Allium cepa was carried out with metanil yellow and carmoisine. They are azo dyes used in food and pharmaceutical products as coloring agents. Allium cepa is considered sensitive indicator of environmental chemicals. Result indicated genotoxic and cytotoxic effects by metanil yellow and carmoisine. The mutagenic and toxic effects increased with time of treatment and concentration.
Food dyes are important component of food in this fast life. Metanil yellow and carmoisine are two azo dyes which are being used at an alarming rate for increasing visual appearance and consumer validity of food. There is a lot of controversy regarding the genotoxicity of these two dyes. In the present study genotoxicity of two food dyes metanil yellow and carmoisine was evaluated using Allium cepa as indicator. The effect of these two azo dyes was determined at concentration of 0.25 %, 0.50 %, 0.75 % and 1.0 % for 24 h and 48 h of exposure period using root meristematic cells of Allium cepa. Some genotoxicity parameters like mitotic indices and chromosomal aberrations were studied. It was found that both metanil yellow and carmoisine caused a significant reduction in mitotic index and also produce different kinds of chromosomal aberrations mostly at higher concentration and longer exposure period. The different kinds of aberrations that were observed in meristematic cells after treatment with both metanil yellow and carmoisine are disorientation at metaphase, metaphase stickiness, anaphase stickiness, anaphase bridge, c-mitosis and chromosome breaks. The genotoxicity of carmoisine was found very high as compared to metanil yellow at all concentrations and exposure periods. Thus it was concluded from the present study that carmoisine and metanil yellow have genotoxic activities and should be taken in very control and limited doses.

Effect of probiotics on obesity-related markers per enterotype: a double-blind, placebo-controlled, randomized clinical trial. EPMA J 2020; 11:31-51. [PMID: 32140184 DOI: 10.1007/s13167-020-00198-y] [Citation(s) in RCA: 42] [Impact Index Per Article: 8.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2019] [Accepted: 01/09/2020] [Indexed: 02/06/2023]
Abstract
Background Prevention and improvement of disease symptoms are important issues, and probiotics are suggested as a good treatment for controlling the obesity. Human gut microbiota has different community structures. Because gut microbial composition is assumed to be linked to probiotic function, this study evaluated the efficacy of probiotics on obesity-related clinical markers according to gut microbial enterotype. Methods Fifty subjects with body mass index over 25 kg/m2 were randomly assigned to either the probiotic or placebo group. Each group received either unlabeled placebo or probiotic capsules for 12 weeks. Body weight, waist circumference, and body composition were measured every 3 weeks. Using computed tomography, total abdominal fat area and visceral fat area were measured. Blood and fecal samples were collected before and after the intervention for biochemical parameters and gut microbial compositions analysis. Results Gut microbial compositions of all the subjects were classified into two enterotypes according to Prevotella/Bacteroides ratio. The fat percentage, blood glucose, and insulin significantly increased in the Prevotella-rich enterotype of the placebo group. The obesity-related markers, such as waist circumference, total fat area, visceral fat, and ratio of visceral to subcutaneous fat area, were significantly reduced in the probiotic group. The decrease of obesity-related markers was greater in the Prevotella-rich enterotype than in the Bacteroides-rich enterotype. Conclusion Administration of probiotics improved obesity-related markers in obese people, and the efficacy of probiotics differed per gut microbial enterotype and greater responses were observed in the Prevotella-dominant enterotype.

Abstract
This study evaluated the mutagenicity and acute toxicity of the juice extract of nutricultured Brassica napus containing vanadium (BECV). The BECV was prepared by nutriculture for 7 days in Jeju water containing vanadium. The mutagenic effects of BECV were investigated using the bacterial reverse mutation test, chromosome aberration test, and micronucleus test. Based on the results of the mutagenicity test, we propose that BECV is not a mutagenicity-inducing agent. In the acute oral toxicity study, male and female Sprague-Dawley rats were administered a single limiting dose of 0.014, 0.14, or 1.4 μg BECV/kg body weight; the rats were then observed for 7 days. No acute lethal effect was observed at the maximal dose of 1.4 μg BECV/kg body weight. In the subacute study, male and female rats were administered once daily, by oral gavage, a dose of 0.028, 0.14, and 0.7 μg/kg body weight of BECV for 28 days. No significant toxicity was observed not only hematological, biochemical, and pathological parameters but also the body and organ weights when compared to controls. The level of BECV with no observed adverse effects in male and female rats was 0.7 μg/kg body weight (concentration of vanadium in BECV) in the subacute toxicity study.
