Review on docosahexaenoic acid in poultry and swine nutrition:Consequence of enriched animal products on performance and health characteristics

引用

Animal Nutrition 2019年第1期5卷 11-21页

作者： Sophie A.Lee natasha Whenham Michael R.Bedford AB Vista Marlborough

Omega-3 polyunsaturated fatty acids(n-3 PUFA) are linked to a variety of health benefits against human disorders and disease. However, the typical western diet is generally low in n-3 PUFA and high in n-6 PUFA, suggesting that the recommended intake of these essential fatty acids is seldom ***, dietary enrichment of animal meat and eggs with n-3 PUFA could help increase consumption of these fatty acids. Fish oils and microalgae(MA) are rich sources of long chain n-3 PUFA, specifically eicosapentaenoic acid(EPA) and docosahexaenoic acid(DHA). Feeding these marine products has been shown to increase DHA content of tissues and yolk, however, this may also lead to an increased requirement for anti-oxidants to prevent oxidative deterioration and associated negative sensory attributes. Nonetheless, increased DHA has been linked to promising results in animal growth, fertility,immunity and bone strength in both pigs and poultry. These findings suggest that feeding DHA-rich ingredients to mono-gastric can enrich human diets as well as providing additional benefits to the animal.

Nanozymes in Point-of-Care Diagnosis:An Emerging Futuristic Approach for Biosensing

Nanomaterial-based artificial enzymes(or nanozymes) have attracted great attention in the past few years owing to their capability not only to mimic functionality but also to overcome the inherent drawbacks of the natural *** advantages of nanozymes such as diverse enzyme-mimicking activities,low cost,high stability,robustness,unique surface chemistry,and ease of surface tunability and biocompatibility have allowed their integration in a wide range of biosensing applications. Several metal,metal oxide,metal–organic framework-based nanozymes have been exploited for the development of biosensing systems,which present the potential for point-of-care analysis. To highlight recent progress in the field,in this review,more than 260 research articles are discussed systematically with suitable recent examples,elucidating the role of nanozymes to reinforce,miniaturize,and improve the performance of point-of-care diagnostics addressing the ASSURED(a ordable,sensitive,specific,user-friendly,rapid and robust,equipment-free and deliverable to the end user) criteria formulated by World Health Organization. The review reveals that many biosensing strategies such as electrochemical,colorimetric,fluorescent,and immunological sensors required to achieve the ASSURED standards can be implemented by using enzyme-mimicking activities of nanomaterials as signal producing components. However,basic system functionality is still lacking. Since the enzyme-mimicking properties of the nanomaterials are dictated by their size,shape,composition,surface charge,surface chemistry as well as external parameters such as pH or temperature,these factors play a crucial role in the design and function of nanozyme-based point-of-care diagnostics. Therefore,it requires a deliberate exertion to integrate various parameters for truly ASSURED solutions to be realized. This review also discusses possible limitations and research gaps to provide readers a brief scenario of the emerging role of nanoz

Unusual switchable peroxidase-mimicking nanozyme for the determination of proteolytic biomarker

作者： Claire McVey natasha Logan Nguyen T. K. Thanh Christopher Elliott Cuong Cao Institute for Global Food Security School of Biological Sciences Queens University Belfast 18-30 Malone Road Belfast BT9 5BN UK Biophysics Group Department of Physics and Astronomy University College London London WC1E 6BT UK UCL Healthcare Biomagnetic and Nanomaterials Laboratories 21 Albemarle Street London W1S 4BS UK Material and Advanced Technologies for Healthcare Queens University Belfast 18-30 Malone Road Belfast BT9 5BN UK

Detection of enzyme biomarkers originating from either bio-fluids or contaminating microorganisms is of utmost importance in clinical diagnostics and food safety. Herein, we present a simple, low-cost and easy-to-use sensing approach based on the switchable peroxidase-mimicking activity of plasmonic gold nanoparticles (AuNPs) that can catalyse for the oxidation of 3,3’,5’5-tetramethylbenzidine (TMB) for the determination of protease enzyme. The AuNP surface is modified with casein, showing dual functionalities. The first function of the coating molecule is to suppress the intrinsic peroxidase-mimicking activity of AuNPs by up to 77.1%, due to surface shielding effects. Secondly, casein also functions as recognition sites for the enzyme biomarker. In the presence of protease, the enzyme binds to and catalyses the degradation of the coating layer on the AuNP surface, resulting in the recovery of peroxidase-mimicking activity. This is shown visually in the development of a blue colored product (oxidised TMB) or spectroscopically as an increase in absorbance at 370 and 650 nm. This mechanism allows for the detection of protease at 44 ng·mL^-1 in 90 min. The nanosensor circumvents issues associated with current methods of detection in terms of ease of use, compatibility with point-of-care testing, low-cost production and short analysis time. The sensing approach has also been applied for the detection of protease spiked in ultra-heat treated (UHT) milk and synthetic human urine samples at a limit of detection of 490 and 176 ng·mL^-1, respectively, showing great potential in clinical diagnostics, food safety and quality control.

Diagnostic utility of flexible fiberoptic nasopharyngolaryngoscopy recorded onto a smartphone: A pilot study

引用

World Journal of Otorhinolaryngology-Head and Neck Surgery 2018年第2期4卷 135-139页

作者： Jason A. Brant Kevin Leahy natasha Mirza Hospitals of the University of Pennsylvania Philadelphia PA USA

Objectives: To evaluate the diagnostic accuracy of flexible fiberoptic examinations of the larynx recorded onto smartphones. Methods: Prospective, blinded study of inpatients requiring laryngoscopy. A live exam was per-formed, then a smartphone was attached to the endoscope using a novel coupling device and the same examination was recorded. The live and recorded exams were evaluated by two lar-yngologists, each blinded to the findings of the other. Results: Eighteen subjects were evaluated. Evaluation of airway patency was identical (Kappa = 1.0 [1, 1]). Evaluation of vocal cord motion was identical for 14 subjects: 9 normal, 3 paretic, 2 paralytic (Kappa = 0.69 [0.38, 1]). Conclusion: There is high correlation between laryngeal diagnoses using live flexible fiberoptic laryngoscopy and recordings using a coupling device to transfer the recordings on to smart-phones. Critical findings such as airway patency and vocal fold motion showed the highest cor-relation.
