Authors: Merenkova S , Zinina O , Stuart M , Okuskhanova E , Androsova N
Published: December 2020

The aim of this article is to review literature data on the terminology, classification and physiological effects of dietary fibers. Results. The scientific studies on the terminology, classification and characteristics of various types of dietary fiber are presented, the sources of dietary fiber and their positive physiological effects are described. Nowadays no consensus definition has been given to the concept of dietary fibers. The authors point to dietary fibers being related to chemical compounds defined by structure, or functional properties, and/or a combination of both structural and functional properties. The authors noted one commonality in these definitions: each mentioned positive physiological effects. The modern classification system for dietary fibers is wide and diverse and can be based on origin, structure of polymers, solubility, ion exchange, sorption or physiological effect. Many studies have shown that dietary fibers can promote human health and help prevent specific chronic diseases that increase mortality and reduce life expectancy. Numerous healthful effects of the dietary fibers have been documented. These include curative and preventive effects for diseases such as obesity, certain types of cancers, cardiovascular diseases, diabetes, and constipation. Conclusion. Fibers are considered before other nutrients to ensure a healthy nutrition. Research continues to contribute new data on the effect of dietary fiber on the human body.

Authors: Kondrashkin P , Baiguzhina O , Shibkova D
Published: December 2020

Aim. The paper aims to evaluate pressure-pain-threshold (PPT) in the paravertebral areas of the back (lumbar, thoracic, cervical levels) in relatively healthy individuals in various functional states. Materials and methods. The study involved volunteer female students (n = 150). Heart rate measurement and tonometry were performed using the B.WELL PRO-33 automatic tonometer. The level of functional readiness for physical exercises was assessed by the method of Kolmogorov et al. (2007). In group I (n = 45), PPT measurements were carried out at rest in the laboratory room. In group II (n = 105), PPT data were obtained before physical activity. Women of both groups were divided into subgroups by the absence (1) or presence (2) of complaints of back pain. PPT measurements were carried out using the Wagner FPX pressure algometer (USA). Standard statistical methods were used for data analysis. Results. A significant effect of the functional state on PPT values was found. In group II, against the background of readiness for physical activity, the mean values of PPT in the paravertebral areas were 20–40 % higher than in group I. The PPT values were the highest in the area of the lumbar spine. Conclusion. Changes in the dynamic stereotype (from a state of rest to readiness for physical activity) lead to an increase in the absolute values of PPT up to 40 %. This phenomenon indicates that the emotional component of physical exercises has an analgesic effect.

Authors: Surnin D , Usachev N
Published: December 2020

Aim. The paper aims to identify the most effective direction in fitness aerobics for the best physical training of middle aged females. Materials and methods. A pedagogical experiment was conducted in March 2018 – November 2018. The experiment was held on the premises of the World of fitness sports club (Togliatti). Ninety (n = 90) females aged from 35 to 50 years participated in the experiment. All females were divided into three groups depending on their fitness discipline (Pilates (EG-1), strip dance (EG-2), step aerobics (EG-3)). To compare the programs, a set of indicators was used that characterize the morphofunctional and somatometric changes in the subjects, as well as the dynamics of physical qualities. Statistical data processing was performed using the Microsoft Office and Statistica for Windows v.6.0 software package. The collected data were described using sample size (n), arithmetic mean (x ~), and standard deviation (SD). Results. The recovery time (according to the functional test) in EG-3 decreased by an average of 0.8, in EG-2 – by 0.5, in EG-1 – by 0.4. Orthostatic test showed that the difference in horizontal and vertical positions reduced and did not exceed 10 bpm. Rate of recovery in step-test in EG-3 decreased by an average of 3.3 s, in EG-2 – by 2.8 s; in EG-1 – by 2.1 s. The strength of the abdominal muscles increased on average by 7 times (69.2 %); muscle strength of the shoulder girdle improved by 8.4 times (40.8 %); strength of the thigh muscles increased on average by 20.2 times (44.5 %); vertebral column mobility improved by an average of 7.2 cm (66.6 %); in EG – 1, coordination abilities improved by 6.3 s (73.9 %), in EG-2 – by 7.4 s (71.3 %), in EG-3 – by 9 s (69.2 %). Indicators of body proportionality after the experiment showed that there was a decrease in the hips by 8.3 ± 1.20 cm; waist circumference reduced by 5.1 ± 1.22 cm; breast circumference reduced by 1.8 ± 0.38 cm. Conclusion. The results obtained prove the greatest efficiency of step aerobics classes compared to other fitness disciplines, which is expressed in a significant improvement of the cardiovascular, respiratory, coordination systems and somatic indicators, as well as in an increase in physical fitness in middle-aged females.

Published: December 2020

Aim. The paper deals with theoretical and experimental substantiation of an individual approach to health-improving female training. Materials and methods. A specific individual orientation of training effects for women aged from 21 to 35 years was determined depending on their somatotypes: asthenic (n = 14), normosthenic (n = 18) and hypersthenic (n = 16). Individual somatotype-based health-improving training programs were implemented by 48 women during a nine-month macrocycle. The following research methods were used: anthropometric measurements, somatotyping, control and pedagogical tests, a set of biomedical methods, pedagogical observation, pedagogical experiment, methods of mathematical statistics. Results. Distinctive somatotype features, body composition, functional status, physical fitness were determined in women engaged in shaping. The asthenic type is characterized by the smallest weight and height, as well as body circumference measurements, vital capacity, hand dynamometry, and body composition data. The hypersthenic type is described by the highest figures for the parameters studied. The normosthenic somatotype is distinguished by average data. Assessment of physical development, functional status and physical fitness in women demonstrated deviations from standard values for most indicators. The individualized method of developing health-improving female training programs based on somatotype characteristics provided statistically significant positive dynamics of physical development, body composition, functional status, physical fitness compared with the initial values. Conclusion. The focus of health-improving training programs for women aged from 21 to 35 years is determined based on morphofunctional and conditioning features that are specific for various somatotypes.

Polyclonal Antibodi-Gold Nanoparticles for Potato Virus Y Detection

Gold nanoparticles are stable colloidal solutions with dimensions of 1-100 nm having surface plasmon resonance with six free electrons. The existing of six free electrons on the surface of a plasmon causes gold nanoparticles to bind easily to various types of bioreseptors including polyclonal antibodies. Polyclonal potato virus Y (PVP) antibodi been successfully conjugate with gold nanoparticles in order to develop a rapid detection for PVY infection in potato plants. The gold nanoparticles was synthetized by the reduction of gold (III) chloride trihydrate (HAuCl4) with 1% sodium citrate. Subsequently, the nanoparticles were used to make gold nanoparticle-antiobody PVY-conjugate. PVY detection was carried out with dot blot method on the nitrocellulose membrane. The results showed that the PVY virus on the membrane can be detected 10-30 minutes after incubation, depend on the concentration of the conjugate and the concentration of the virus in the sampel. The use of gold nanoparticle conjugates can increase the efficiency of the immunodot blot method in about 1 hour, and this method can be developed to be a lateral flow system for field detection of PVY.

THE RIGHT TO INCLUSIVE EDUCATION FOR CHILDREN WITH DISABILITIES IN THE REPUBLIC OF NORTH MACEDONIA: OPPORTUNITIES AND CHALLENGES
Authors: Stankovska Gordana , MEMEDI IMRAN
Published: December 2020

A child is a member of a vulnerable group in societies. Children's rights are equal for all children and they cannot be denied, because they are a birthright. However, throughout the world, children with disabilities and their families constantly experience a barrier in regard to the enjoyment of their basic human rights and to their inclusion in society. Their abilities are overlooked, their capacities are underestimated and their needs are given low priority. The barriers they face are more frequently a result of the environment in which they live rather than a result of their impairment. The situation began to change only when requirements to include disabled children in the education system were introduced in legislation. Following the example of other countries worldwide, the Republic of North Macedonia introduced inclusion of children with disabilities in the mainstream educational process, because the right to education is a right for all children, including the ones with special educational needs. For this purpose, the Republic of North Macedonia implemented a series of changes in the educational system for successful inclusion of children with special educational needs. Hence, the main aim of our paper is to represent the actual situation in Macedonian schools regarding the problem of educational inclusion of students with disabilities in the regular school system. The research methods are based on document studies and case studies about changes in social and educational policies for students with disabilities and special educational needs who are included in primary and secondary education. At the same time we shall present some guidelines for teachers who work with these children and future directions for a proper inclusion system in the Republic of North Macedonia, because every child has a fundamental right to education and must be given the opportunity to achieve and reach an acceptable level of learning. In this frame, school societies try to support full participation of students with disabilities in areas of their lives on equal terms, conditions, social justice and basic human rights.

Authors: Fernando Ávila , David Muñoz , Margarita Ríos , Hernando Camacho , Diana Londoño
Published: December 2020

De acuerdo al departamento de planeación nacional DNP, en Colombia 972 de los 1102 municipios son de sexta categoría, en el departamento del Tolima 43 de las 47 áreas son de sexta categoría. Además, dentro de las oficinas de control interno de estos municipios se ha demostrado que existe ineficiencia en el cumplimiento de roles (liderazgo estratégico, enfoque preventivo, evaluación de la gestión de riesgos, evaluación y seguimiento (Auditorías internas), relación con las entidades de control externo) Esto ocurre por diferentes razones (Métodos, procesos y personal). Por esto, esta investigación tiene como objetivo mejorar este proceso, desarrollando una herramienta para realizar auditorías internas integrales en municipios de sexta categoría, tomando como referencia las normas técnicas: NTC ISO 19011:2018, NTC ISO 45001:2018, NTC ISO 14001:2015, NTC ISO 18091:2019, articulado con la guía de autoría para entidades publicas, Decreto 1072 de 2017, Ley 99 de 1993 y el Modelo Integrado de Planificación y Gestión - MIPG v2 respectivamente. La investigación se desarrollará a través de un enfoque cualitativo de carácter exploratorio y descriptivo, analizando el proceso de auditoría e identificando el cumplimiento y prioridades de las referidas normas técnicas versus la legislación, para posteriormente diseñar y validar una aplicación que permita orientar al auditor interno de los alcaldes y oficinas de control interno de los municipios de sexta categoría en el cumplimiento de sus funciones. Es importante resaltar que realizar procesos de auditoría integral con el apoyo de la herramienta propuesta conlleva los siguientes beneficios: integra información para la toma de decisiones, prevención de ocurrencia de riesgos, favorece el logro de los objetivos institucionales, aumenta el índice de transparencia, mejora la planificación y los recursos gestión, reduce tiempos y esfuerzos de operación, reduce sobre costos por actividades redundantes, mejora el control de procesos, favorece el cumplimiento legal y otros grupos de interés, facilita la apropiación. Con la investigación y desarrollo de la herramienta se concluyó que en la mayoría de los países latinoamericanos no existen sistemas estructurados de evaluación del desempeño de los municipios que integran el sistema, o se encuentran en etapas iniciales. Los municipios de sexta categoría tienen deficiencias en el ejercicio de las auditorías internas debido a diferentes factores internos y externos, provocando una mala práctica del ejercicio, que, con la ayuda de una herramienta de planificación y realización de auditorías internas integrales, permite a los municipios de sexta categoría cumplir adecuadamente con las regulaciones y proporcionar valiosos aportes a la alta dirección para la toma de decisiones.

Published: December 2020

El crecimiento de la industria naviera en el Perú y la ampliación de la zona portuaria del Callao, Pisco, Paita y Salaverry, permiten el ingreso de buques de gran calado. En los años 2009-2010, se reportó el ingreso de especies invasoras a través del agua de lastre en el Callao. Se realizó una evaluación del agua de lastre en los buques que arribaron al puerto del Callao en los años 2010 y 2012.también se evaluó la calidad acuática de los puertos de Paita Salaverry, Callao y Pisco entre 2011 y 2013. Los resultados muestran que en el agua de lastre los recuentos de coliformes fueron bajos de < 2 a 8 NMP/100ml, pero se registró a las bacterias Vibrio parahaemolyticus y V. vulnificus y especies fitoplanctónicas como Heterosigma akashivo y, Skeletonema costatum sp fueron las más representativas. Las aguas marinas de los puertos tenían valores normales de temperatura <20 ° C y salinidades > 35.1 ups, pero la calidad acuática fue afectada por actividades antropogénicas con valores elevados de coliformes termotolerantes en el Callao de 1,6x106 NMP/100ml. Las especies de fitoplancton dominantes producen floraciones algales Dictyocha fibula y Prorocentrum micans en Paita, Prorocentrum minimun, A. sanguineum en Salaverry en 2012, Heterosigma akashiwo y Akashiwo sanguinea,en el Callao en 2013. En el puerto de Pisco, las especies más abundantes fueron Cochlodinium polikrykoides en 2011 y Alexandrium peruvianum en mayo de 2012. El agua de lastre transporta especies exóticas invasoras que pueden causar graves efectos en el ecosistema marino, la salud humana y la economía, por lo cual debe fortalecerse el monitoreo de puertos de mayor tráfico marítimo.
Zonamiento mineralógico con difracción de rayos X para la optimización del tratamiento metalúrgico en el Yacimiento Toromocho
Authors: Flores Barrón Ronald Eugenio , Guadalupe Gómez Enrique
Published: December 2020

El yacimiento Toromocho es un yacimiento pórfido skarn con una extensión de 5 km por 6 km, geológicamente está constituida por rocas volcánicas del Mitu y calizas del Pucara e intrusivos terciario. La mineralización, mayormente está dada por vetas que atraviesan de Este a Oeste en todo Morococha que están rellenadas con minerales de Pb, Zn y Ag mantos de Zinc emplazados en las calizas y en forma diseminada, también emplazados en las calizas y en los contactos volcánicos–caliza-intrusivo y también cuerpos piritosos diseminados con mineralización de cobre. En cuanto a su mineralización es muy compleja encontrando mantos, vetas, stockwork, diseminado cuerpos encontrando minerales que afectan mucho el tratamiento metalúrgico como es el arsénico. Los resultados de los estudios de XRD nos permite caracterizar los minerales existentes en el yacimiento, de los minerales contaminantes para poder realizar un buen blending, controlar el talco, fluor magnesio, zinc, etc. A mayor contenido de talco en CMC es más efectivo a un con gangas naturalmente flotables para lograr un grado mínimo de 20% requiere 700g/l de CMC. Según acuerdo con el área de metalurgia, planeamiento y geología se llegaron a nos términos de no considerar algunos minerales penalizables como es el fluor, porque en la parte central del yacimiento se tiene alto fluor como también alto grado de cobre que esto permite realizar un blending para poder levantar la ley de cobre, pero en la planta metalúrgica se tiene que activar el proceso de la planta de molibdeno para poder limpiar el mineral con alto fluor y talco con la adición del NaSH.

El hombre «creador de sí mismo». Actualidad del pensamiento de K. Wojtyła sobre la libertad
Authors: Buch Lucas
Published: December 2020

El centenario del nacimiento de K. Wojtyła es una buena ocasión para volver sobre su propuesta antropológica, y preguntarse si sigue siendo una respuesta significativa. El presente artículo parte de una sencilla descripción de la mentalidad actual, reconociendo en ella cinco valores o ideales. Después, presenta cinco conceptos que articulan la exposición que hace Wojtyła de la libertad en su obra más acabada, Persona y acción, y muestra cómo interpelan a aquella mentalidad, al mismo tiempo que la obligan a ampliar sus concepciones. Esos cinco conceptos son: autodeterminación, integración, valor personalista, realización y participación.

¿Invertir la intencionalidad? Henry y la absorción de la intencionalidad en el ser
Authors: García-Baró Miguel
Published: December 2020

En este trabajo se propone una revisión de la fenomenología de la vida de Michel Henry y su relación con la intencionalidad, tal como esta es pensada en y por Husserl. Se pasa revista al modo en el que el fundador del método fenomenológico se ocupa de cuestiones centrales de la fenomenología de la vida, así como de la forma en la que Henry habla de la vida, la autodonación, la autorevelación, la verdad, el cuerpo originario o absoluto, etc. La tesis es que en el fenomenólogo francés no se trata, en sentido propio, de una inversión de la intencionalidad, sino de una “absorción en sí misma”.
La experiencia del otro en la arquitectónica richiriana. Notas sobre el concepto de "Phantasie"
Authors: Daturi Davide-Eugenio
Published: December 2020

¿Qué significado tiene el concepto de Phantasie en Richir? ¿Cuál es su lugar en la fenomenología arquitectónica? ¿Y cuál es su relación con el Leib, la idea de un cuerpo propio que este autor retoma de Husserl? El objetivo de este artículo es contestar a estas preguntas introduciendo el camino seguido por el filósofo belga Marc Richir que, poniendo en tela de juicio desde sus primeras obras la noción husserliana de sujeto trascendental, se dirige a una propuesta de refundación de la fenomenología. Para hacerlo indagaremos algunos conceptos centrales para este autor: yo despierto/yo dormido, temporalidad, stimmung, interfacticidad.

Credible intervals are also derived. A simulation study is presented to discuss the behavior of Bayes estimators. Applicability of the undertaken study is highlighted using three real data sets.
Bivalve Mariculture in Two – Way Interaction with Phytoplankton: A Review of Feeding Mechanism and Nutrient Recycling
Authors: MORUF Rasheed Olatunji , OKUNADE Gabriel Femi , ELEGBELEYE Owoyemi Wahab
Published: December 2020

Bivalve mariculture is a type of molluscan farming done in open seawater on racks, rafts or longlines where naturally occurring phytoplankton serves as a key food item, introduced into the enclosures with the normal circulation of seawater. Increasingly, the reverse trophic interaction is being recognized; dissolved inorganic and organic waste compounds released by metabolically active bivalves can supply phytoplankton with nutrient and energy requirements for their growth. This two-way interaction can be viewed as a type of community symbiosis developed over long evolutionary timescales. The extent to which this affects overall nutrient budgets and thus primary production is related to the system flushing rate and residence time. Here we reviewed the feeding mechanism and nutrient recycling activities of bivalve and also emphasized the role of phytoplankton as a key nutritional live feed in sustainable bivalve mariculture. Bivalves influence nutrient dynamics through direct excretion and indirectly through microbial mediated remineralisation of their organic deposits in the sediments. The quantitative knowledge of bivalve - phytoplankton trophic interactions in coastal waters will inform bivalve mariculture development to effectively serve the needs of both seafood production and ecosystem restoration.

Pawpaw or Northern banana (Asimina triloba (L.) Dunal) is the only representative of the Annonaceae family that can be cultivated in temperate areas. The increasing demands from the consumers for this nearly unknown fruit with high nutraceutical potential require specific researches. The aim of this study is to present the fruits pomological characteristics for 23 genotypes analyzed, cultivated in the Bucharest area. For each genotype yield, fruit size, average number of seeds per fruit, average weight of seeds and seeds size were measured. Fruit biochemical analyses as dry matter, total soluble solids, ascorbic acid content, acidity, were done for several genotypes. Fruit quality evaluation through sensorial analyses was conducted for 13 genotypes. The most valuable genotypes from the Experimental field according to the analyses performed and the consumer’s preferences are taken in consideration for further research.

Authors: CADAR Roxana Larisa , POCOL Cristina Bianca
Published: December 2020

The complexity of medicinal and aromatic plants products makes difficult to asses their safety and efficacy. A qualitative research method, called hybrid forum has been used in order to better understand the risks and benefits of those products, from the perspective of three key components: the manufacturing process, from raw material to the finished product, safety and quality assurance, consumers’ perception and biomedical context. The discussion forum took place in November 2019 in Cluj-Napoca and it was organized in two parts: the first addressed to researchers and actors in the field (14 stakeholders) and the second to the general public (23 participants). Critical points and limitations in the field of products obtained from medicinal and aromatic plants have been identified by both the specialists (poor cooperation between actors; lack of monitoring of product quality; increase self-medication), and the general public (difficulties in making informed choices; reluctance to pharmacists’ advice).

Published: December 2020

Four young plum orchards from Iaşi county, two of these established by using propagated material in Romania, and the other two with material from Austria, Czech Republic and Netherlands, were surveyed by visual observation of viral symptoms. Then, trees were sampled and tested for the presence of six viruses (PPV, PDV, PNRSV, ACLSV, ApMV and MLRSV) by serologic assays. A high rate of PPV infection (78% and 79%, respectively) was determinated in the two orchards established with planting material propagated in Romania, and a rate of 5% PDV infection was found in one of them. A rate of 2.5% PPV infection was determined in the orchard established with propagated material in Austria and Czech Republic, and no PPV infected tree was found in the orchard set up with material propagated in Netherlands. The infections with PNRSV, ACLSV, ApMV and MLRSV were not detected in the four orchards surveyed.

Published: December 2020

Currently, in Romania there are just a few autochthonous white kidney bean varieties and this is the main reason why Vegetable Research Development Station (VRDS) Buzau has chosen a breeding program for this species. The aim of this study was to assess the main quantitative characteristic of a new cultivar of kidney beans, ‘Doina’. The correlation matrix showed a strong relationship between plant height and bush diameter and also with leaf length and a negative correlation between plant height and pods mass per plant. The cultivar has a yield potential of over 3000 kg/ha and a compact maturation of the pods, being suitable for mechanized harvesting. An important feature is plant hardiness, due to local genetic resources used in the breeding program. During the research it was found that the variety has a distinct phenotypic expressiveness with a high yield and quality potential.

Basella alba is an underutilized plant with great food and medicinal potential, newly acclimatized in Romania at Vegetable Research and Development Station (VRDS) Buzau. For over 10 years, the Genetic, Breeding and Biodiversity Laboratory has studied a number of 12 genotypes from Basella spp. of these, two accessions (L5 and L8) showed distinct phenotypic feature. The experience has been done in randomized blocks with three replications, and the number of plants analyzed for each variant was 50. On L8 accession, the anthocyanin coloration was not present, unlike accession L5 which features a strong anthocyanin coloration, especially along the stem and on the dorsal side of the leaf. Specifically B. alba var. rubra shows a leaf width of 14.8 cm and a weight of 20 g, and the B. alba shows a leaf width of 21.4 cm and a weight of 27.5 g. Basella alba recorded the highest percentage in dry matter in the smallest leaves, namely 7.69% and Basela alba var. rubra registered the highest percentage in dry matter also in the small leaves, of 7.98%. The aim of this study was to assess the morphological traits in order to patent a new acclimatized species in Romania. The study was finalized with one variety (L5) that has been successfully qualified for DUS test (Distinction, Uniformity and Stability) and soon will be registered in the Official Catalogue of Species and Varieties of Cultivated Plants.

Published: December 2020

The experiment aimed to evaluate some of organic products within a treatment scheme against Eurytoma schreineri Schreiner., on two different plum varieties: Stanley and Reine Claude d’Althan. An experimental scheme of organic treatments by using seven organic products with insecticidal effect was developed and used for evaluation in the field. There were three variants taken into account: organic, conventional and untreated, used as control. Each variant consisted of eight trees belonging to Stanley and Reine Claude d’Althan cvs., four trees for each variety. The frequency occurring of Eurytoma schreineri was evaluated along two consecutive years (2019-2020). Overall results confirmed the sensitivity of Stanley cv. to Eurytoma. schreineri. On the other hand, the results showed that the organic scheme developed was unsatisfactory and there is a risk of considerable losses for farmers who opt for this kind of scheme.

This study intended to establish if Cd and Pb in the livers and kidneys of bovine and ovine slaughtered in the study area exceeded to concentrations maximum limit proposed by the European Commission (EC) 2006. After digestion of samples, Cadmium and lead concentrations were determined by Graphite Furnace Atomic Absorption Spectrophotometry (GFAAS). The results of our study have shown that lead and cadmium concentrations depend on age and species. The average fresh weight levels of liver and kidneys of bovine animals were about (0.319 mg/kg and 0.337mg/kg) for Cd and (0,502mg/kg and 0.497mg kg) for Pb, while in ovine, mean concentrations in the liver and kidneys were (0,241mg/kg and 0.232 mg/kg) for Cd and (0.259 mg/kg and 0.265 mg/kg) for Pb. Concentrations above the maximum limit proposed by the EC 2006 for Pb and Cd have been detected in some liver and kidney samples from bovine older than 4 years and in ovine over 1 year old .Statistical analysis revealed a very significant (P<0.01) difference in Cd concentrations in the liver and kidneys between age groups and species.

Published: December 2020

In recent decades, secondary infection bacteria quickly increased their pathogenicity in both human and veterinary patients, due to their continuously increasing antibiotic-resistance. When such bacteria intervene in infections as orf in sheep, they can determine an important impact either in the sanitary or in the economic aspect of the brreding sector. Considering the relatively high spread and economic impact of orf in Romanian sheep, this research aimed to estimate the complexity of the secondary infections in diseased sheep in connection with the severity of the lesions displayed. The research was conducted in five herds, on 3 to 96 month old sheep, with orf lesions, scored from mild to severe. The bacteria were isolated from the lesions and identified by cultivation on broth and agar plates plus identification by use of API galleries. The severity of the lesions did not seem to be influenced by the number of bacterial species isolated, but by the herd environment and individual pathogenicity of the isolates.
Hibiscus Tea and Health: A Scoping Review of Scientific Evidence
Authors: CJ Etheridge , EJ Derbyshire
Published: December 2020

Over the last few decades, health evidence has been building for hibiscus tea (Hibiscus sabdariffa L. Malvaceae). Previous reviews show promise in relation to reducing cardiovascular risk factors, hypertension and hyperlipidaemia, but broader health perspectives have not been widely considered. Therefore, a scoping review was undertaken to examine the overall health effects of hibiscus tea. A PubMed search was undertaken for metaanalysis (MA) and systematic review papers, human randomised controlled trials (RCT) and laboratory publications investigating inter-relationships between hibiscus tea and health. Twenty-two publications were identified (four systematic/MA papers, nine human RCT controlled trials and nine laboratory publications).Strongest evidence exists in relation to cardiovascular disease, suggesting that drinking 2-3 cups daily (each ≈ 240-250 mL) may improve blood pressure and potentially serve as a preventative or adjunctive therapy against such conditions. Emerging evidence exists for favourable effects on lipid profiles, insulin resistance, oxidative stress and inflammation. Further research using larger and longer human studies is warranted.
