Authors: Miloradova Natalia , Okhrimenko Ivan , Dotsenko Victoria , Matiienko Tetyana , Rivchachenko Olena
Published: June 2022

The communicative component of the investigator’s professional activities is a dominant one, as it demonstrates the employee’s ability to organize work on the basis of professionally balanced communication with the objects of interaction. The stage of obtaining higher education in institutions with specific learning environment is a sensitive period for the development of the main sociogenic structures of personality and the development of professional identity of future professionals. This period is characterised by a purposeful mastering of the system of professional knowledge and skills, formation of a holistic view of the professional community, which results in awareness of professional readiness. The use of training technology in the training of investigators helps to increase the efficiency of the professional training process, based on the basic principles of personality-oriented education. The aim of our research is to study the process of formation of components of communicative competence in future investigators of prejudicial inquiry agencies with the help of training technologies. Appropriate psychodiagnostic tools were used to solve this purpose, which was tested during the training of specialists for prejudicial inquiry agencies. Most of the respondents stated the existence of satisfaction with participating in the training courses, awareness of the importance of its informativeness and practical orientation. Post-training testing emphasized the participants’ rethinking of the value of interpersonal relations; growing desire to help and show warmth and friendliness in relations with others; the expediency and effectiveness of the use of cooperation and compromise in resolving conflict situations within a professional and personal environment.
Overcoming the Crisis of Intellectuals: Reconstruction of Educators` Professional Identity and Status
Authors: Yacuna Olena , Marusynets Mariana , Palko Tetiana
Published: June 2022

The authors of the article with reference to the discussions about the status of knowledge in the postmodernism discourse and the "crisis of the intellectual" presented in the works by J.F. Lyotard and Z. Bauman, consider these issues in the context of other social challenges. Interpreting the conducted empirical research results, the research also focuses on the multidisciplinary theoretical analysis of philosophical, psychological and pedagogical literature.
The authors note that in the absence of metanarratives, the phenomenon of intellectuals and intellectual work is transformed: postmodern epistemology has changed the opportunities of mass education about how things should stand / what to have / how to act into the multiple / polyphonic / variable / fragmentary / collage dissemination of knowledge. As an argument in the "crisis of intellectuals" discussion, the authors analyze the educators` need and motivation sphere emphasizing constant knowledge enhancement to be a priority for them, which logically affects professional identity reconstruction carried out through self-reference.
The paper presents an opinion that intellectuals lack self-perception as a reference social group. We conclude that in the information society, public interaction with the media affecting the reconsideration of the intellectual`s role and status serves as a basis for their legitimation.
The results of the conducted survey enable us to conclude that raising educators` intellectual level affects their competences in professional practices. The status of the intellectual-educator is legitimized by their activity in training sessions, discussions, meet-ups and other events. The study presents an algorithm for constructing the intellectual-educator in the conditions of social reality challenges.
The research substantiates demand for the intellectual-educator who is IT literate, capable of professional reflection, open to change, motivated for continuous self-development, ready for the reconstruction of professional identity from a knowledge transmitter to an erudite, a creative coach, a supervisor and a moderator.

Published: June 2022

The article is devoted to the consideration the problem of the phenomenon of an unreliable narration in the British intellectual prose of the second half of the twentieth century (Golding, Murdoch). The meaning of the words “narrator”, “unreliable narration” is investigated. The unreliable narration is reviewed based on the example of the novel “Rites of Passage” by Golding (1980). It is noted that the aforementioned work has a vibrant didactic component. It has been found that Golding uses a wide range of narrative techniques. The emphasis is made on the critical analysis by other literary scholars of the novel “Rites of Passage” by Golding. The use of narrative strategies in accordance with the scientific classification by Genette (1980) is investigated. The markers of unreliability of the narrators are emphasized. Attention is focused on the fact that a high degree of unreliability is based on the limited knowledge of the heroes, direct participation in the events, a problematic system of values. It is noted that the unreliability of narration in the novel “Rites of Passage” by Golding forces the reader to doubt not only the narrator but oneself. The use of the narrative method in the intellectual prose of the British writer Iris Murdoch is investi-gated. It has been found that the novel “The Black Prince” by Iris Murdock (2006) is one of the best examples of an unreliable narration. The genre specifics of the novel are emphasized, which combines the forms of the diary, of the memoir and of the confession. In addition, Murdoch creates a narrative strategy, which combines signs of various forms of “I am the narrator” within the framework of one narrative. In addition, “The Black Prince” is a unique model of modern artistic and philosophical metatext genre formation.

Published: June 2022

The article analyses the modern assimilations of the definition ‘dialog’ and its rendering by the world academic community. Attention is drawn to the exceptional empirical significance of dialogics as a general scientific universal. The etymology of dialogue as a key category of philosophical, educational and pedagogical knowledge is identified. The evolution of the lead notionalists` ideas about the kernel and nature of dialogue that are relevant of the humanity itself, human mind and constant search of true knowledge is studied. A parallel is drawn between Socratic dialogue and dialogue in the postmodern educational and philosophic discourse. The problem of the antique thinkers` understanding of dialogue is studied discretely. The contemporary approaches to the fundamentals of dialogism, as outlined in the works of the lead theorists, are studied from the antiqueness to these days. It is highlighted how relevant and applicable for educational philosophy of the XXI century ‘G. Skovoroda`s dialogues’ are. It is ascertained that setting dialogue as autonomous subject of research of a particular school of thought reaches the works of L. Feuerbach with its thesis origins, but gets its final formulization in the works of M. Buber. The author dwells on the main theses of the approach of M. Bakhtin about the dialogic sources of the human beingness. The content and scope of the concepts ‘dialogical pedagogics’, ‘interactive dialogue’, ‘egalitarian dialogue’ are analysed. The advantages and disadvantages of the idea ‘knowledge building’ are studied. It is accentuated that the origins of many contemporary dialogue theories and methodologies date back to the ancient times and represent the attempts to integrate the ‘Socratic dialogue’ into the postmodern discourse. The state of adaptedness and conformance of the contemporary theories of dialogue to challenges of digitalisation and globalisation of the postmodern educational-philosophical space is studied.

Published: June 2022

The urgency of the issue in question lies in the need to improve anti-discrimination legislation in Ukraine. The article aims to summarize the current state of combating discrimination in sports. Research methods include analysis, generalization, and the formal-logical method. The article summarizes international acts that promote the prohibition of discrimination  and the need to combat it. One of the main problems in world sport is racial discrimination, and there are three types of racism in sports. The main disadvantage of laws that lead to imperfect prosecution mechanism is entirely criminal liability for discrimination, even though the law on preventing and combating discrimination also implies administrative and civil liability. The article analyzes some positive foreign experience in combating and counteracting in sports. It shows that the priority areas for combating and counteracting discrimination in sports in Ukraine should be: (a) improving the legislation in terms of prosecution; (b) establishing a special body responsible for combating and counteracting discrimination in sports; (c) introducing educational tools in schools and among members of sports organizations that promote human rights, regardless of race, colour or other characteristics. Emphasis is placed on the fact that an effective mechanism of legal regulation together with preventive measures should guarantee the protection of the rights of both athletes and fans. The obtained results can serve as the basis of legislative proposals to improve the fight against discrimination in sports, which will ensure the protection of human rights.

Ascendant and Descendant Types of Thinking and the Impact on Tolerance as an Educational Value
Authors: Castaian Doru Valentin
Published: June 2022

This article will explore the pattern of conflicts between secular thinking and religious beliefs from the perspective of critical thinking and analyse the potential that this conflict holds for increasing tolerance inside mixed society such as in Romania. It is often said that the ability of thinking critically deeply erodes the propensity towards religious faith and there are numerous study results that back up this assertion. This article tries to explain that  religious faith becomes fully understandable only in some larger pattern that shapes morality, cognitive strategies and social practices and this is true for secular thinking as well. We can name this patterns ascendant, respectively descendant. Ascendant thinking derives and explains higher level practices beginning from lower level entities through progress and emergence and for this kind of thinking, morality and cognition are an open fields that can be indefinitely improved. This kind of thinking embraces novelty and creativity and aims at human beings becoming capable of managing this novelty. The descending model derives from and explains the lower levels through complex and immutable entities and will tend to see novelty as change capable of breaking their models and therefore act towards neutralizing novelty through interpretation. Information and practices that cannot be neutralized will be counted as abnormous. The article comes forward with a comparative analysis between these two opposing patterns, showing that this interpretative frame is valid in retrodiction and that it can fundament concrete predictions. It will also show that critical thinking is permitted and can fundament a space for compromise and dialogue between religious and secular people.

Designing a conceptual model on the relationship between social intelligence and organizational commitment
Authors: Mohadesi Elahe
Published: June 2022

Organizational Commitment is one of the important issues in the field of organizational behavior. The extension of Organizational Commitment is due to its role in efficiency and effectiveness of enterprises, because it is an attitude which declares both the identity of employees in their organizations and the extent they get involved in organizational activities. Affective Commitment, Continuous (Continuance) Commitment, and Normative Commitment compose the three major dimensions of Organizational Commitment. Since most organizations are changing, their leaders must cope themselves with the alterations in order to sustain and develop the company in new environments. An important feature which can help the leaders or managers to fully encounter the problems will be Social Intelligence. Social Intelligence is the ability to understand the people and manage them to act wisely in their human communications. Social Intelligence, as an ability of establishing relationships with others, is a factor which can connect the managers and employees together, and it also reinforces their communications. The six dimensions of Social Intelligence, as one of the most important elements in effective communications, are: Memory (ability to remember names and faces of people), Patience (Calm Endurance under stressful conditions), Cooperativeness (ability to interact with others help them view matters from all angles), Confidence Level, Tactfulness, and Sensitivity (firm trust in oneself and ones chances, delicate perception of the right thing to say or do, and to be acutely aware of and responsive to human behavior), Recognition of Social Environment (ability to perceive the nature and atmosphere of the existing situation), and Sense of Humor (Capacity to feel and cause amusement and be able to see the lighter side of life). This study aims to design a conceptual model on the relationship between Social Intelligence and Organizational Commitment based on the new concepts of the mentioned variables.

Legal consequences of Brexit for UK regions and theoretical foundations of legal mechanisms for preventing secession
Authors: KODANEVA Svetlana I.
Published: June 2022

Introduction. The article shows that as the number of ethno-national conflicts increases in almost all parts of the world, secession processes are becoming more and more popular. At the same time, the legal and political mechanisms for preventing secession may differ radically depending on national characteristics. But even those mechanisms that have shown their effectiveness for a long period under certain (crisis) conditions stop working, forcing states to look for new tools to prevent secession of their regions. The purpose and objectives of the study. The purpose of the study is to study the experience of preventing secession of the national regions of the UK in the process of leaving the EU. It is argued that the strict instruments of limiting the autonomy of the re-gions were not only ineffective, but increased the risk of the collapse of the country. The task of analyzing changes in the regional policy of the United Kingdom in the Brexit process is set. Methodology. The methodo-logical model of A. Liphart, the classical approach of A.V. Daisi to the definition of parliamentary sovereignty is used. General scientific methods of generalization and system analysis are also used. The results of the study. It is proved that tough tools to prevent secession in the crisis conditions of the UK’s withdrawal from the EU proved ineffective and, on the contrary, stimulated separatist sentiments in the national regions of the country. Conclusion. It is concluded that only the use of flexible forms of interaction and the formation of new partner-ship instruments allowed to avoid secession of regions. This required the development of new legal and political instruments of interaction and cooperation between the central government and local elites.
Evolution of juvenile justice in the Russian legislation of the 20th century
Authors: MIRZOYAN Mariya A.
Published: June 2022

The development of legislation in the field of protection of children's rights is one of the priorities of the policy of the Russian Federation. Based on this, the issue of the creation and functioning of the system of juve-nile courts in Russia is often discussed, but scientists and researchers have not come to a consensus on this issue. At the same time, the peculiarities of juvenile justice in the period of the Soviet Union are of interest, since many researchers believe that during the indicated period juvenile justice did not exist in our country. The purpose of this scientific article is to study the history of juvenile justice and all its manifestations during the existence of the Soviet Union, as well as to identify its characteristic features throughout the designated period. Dialectical and historical methods were used as the main research methods, which made it possible to follow this legal insti-tution in its dynamics. In addition, analysis and synthesis were used as methods, as well as a comparative ap-proach, which made it possible to identify the features of juvenile justice at different stages of the twentieth cen-tury. Based on the results of consideration of the chosen topic, it was found out that the beginnings of juvenile justice were laid at the beginning of the twentieth century before the October Revolution of 1917, which was ex-pressed in the actual existence of juvenile courts. It was revealed that the period from the 1930s to the 1950s was characterized by an increased level of responsibility for crimes committed by minors. During this period, the status of minors as subjects of a crime practically did not differ from the status of adults. It is concluded that since the 1950s, responsibility for crimes committed by teenagers has been mitigated, guarantees appear in the Criminal Code that ensure the protection of the rights and freedoms of minors.

Published: June 2022

Indonesia is still facing various environmental problems due to increasingly massive and inappropriate mining activities. Therefore, land restoration is a basic practice in the rehabilitation of mining damage. This study aims to examine empirically the reality of the relationship between the community and PT RBT and strengthen social capital in carrying out post-mining land restoration activities. This study used the descriptive qualitative method. Data were collected through in-depth interviews and a literature study. The results showed that social relations became the main indicator in supporting the formation of trust, cooperation, and networks. Elements of social capital are packaged in the form of community participation in various post-mining land restoration activities. This is done to minimize the level of environmental damage that has increased massively, marked by the ex-mining pit that occurred in Bangka Belitung. The relationships formed are certainly expected to provide feedback for villages that run post-mining land restoration programs. This study concludes that the existence of bonding and bridging social capital that works well will facilitate the continuity of the post-mining land restoration programs.
Causes and remedial measures of presenteeism in the post Covid-19 era workplace: Insight from job demands-resources theory
Authors: Abasilim Ugochukwu D. , Adebajo Oluwatumininu O. , Gberevbie Daniel E.
Published: June 2022

The COVID-19 pandemic has put many organizations under pressure to remain active and profitable despite the compulsory long break it gave everyone. There is growing concern that many employees are under pressure to be present at work to fulfil job demands that were not met at the height of the COVID-19 pandemic. This situation has given rise to presenteeism, where workers do not work to their maximum potential. Several theories account for the reasoning behind presenteeism. This paper examines the job demands-resources theory of presenteeism related to the causes and remedial measures that can be put in place in coping with the consequences of presenteeism in any given organisation. Secondary data sources were adopted for this study. The data collected were analysed based on the research questions and presented thematically. The findings reveal that most organizations continue to increase the workload without the required resources necessary to accomplish the job demands. The study recommends that those at the helm of affairs should note the job demands assigned to their employees and make available all the resources to attend to the job demands in order to achieve the overall good of the organization even in the era of the COVID-19 pandemic.
CONTACT THERMAL RESISTANCE BETWEEN THE FIN AND PIPE-BASE FOR COMPOSITE HEAT TRANSFER SURFACES
Authors: Lishchyshyn V. , Vozniuk M. , Vorobyov M. , Pismennyi E. , Rudenko A.
Published: June 2022

Experimental setup for investigation of contact thermal resistance (CTR) of composite heat-exchange tube, made of flat-oval steel tube – base and aluminum fins, which are connected to the base by means of contact welding, has been developed. By direct measurement, the СTR values for a composite heat exchanger tube are compared to the CTR values for three types of bimetallic tubes with rolled aluminium fins: carbon steel 20 base tube, stainless steel 1X18H10 base tube and brass base tube. It is established that for a composite heat-exchange tube the mean thermal resistance of contacting surfaces doesn't depend on the density of supplied heat flow and makes constant value Rk = 2,75×10–6 Km2/W, that is practically equal to zero for engineering calculations and it is possible to neglect it. For composite heat-exchange tube the application of contact welding technology makes it impossible to deteriorate thermal contact between monorail and tube due to temperature fluctuations in the process of operation of heat-exchange apparatuses. The results obtained show that the composite surface with welded aluminium monofin has two orders of magnitude lower CTR than the heat exchange surfaces made of widely used bimetallic tubes of all known types. This provides the highest heat transfer coefficient.

WATER DESALINATION USING ICE FREEZING IN ICICLES
Authors: Puhoviy І. , Petrechuk A.
Published: June 2022

The aim of the study is to investigate the effect of initial salinity and water flow rate on desalination processes in icicles formed on horizontal nozzles.

Experimental installation, is a frame on which are fixed: a container with initial salt water, impact surface, horizontal nozzles. Initial saline water of 10-30 g/l flowed out through the hole, fell and crushed against the impact surface, and then froze on the nozzles in the form of icicles. To investigate the degree of salinity, the icicles were divided into equal parts and melted.

The results of the investigation show that the obtained water contains the most salts in those parts that are closer to the bases of the borules. At a flow rate of 2 ml/sec, the borules grew to their full length. The level of the option was defined as the ratio of initial water solubility to the received solubility and was 1.5 to 4, higher values were obtained at the flow rate of 1 ml/sec, and at the first intervals.

Conclusions: The results of experiments showed that it is impossible to refine brackish water in 1 cycle. To obtain drinking water with salt concentration less than 0.5 g/l it is necessary to use several cycles of freezing-melting or to combine with other methods of desalination. It is necessary to control the optimum water consumption to ensure a higher degree of (solidification)desalination.
Soil, vine, climate change; the challenge of predicting soil carbon changes and greenhouse gas emissions in vineyards and is the 4 per 1000 goal realistic?
Authors: Schultz Hans
Published: June 2022

The evaluation of the current and future impact of climate change on viticulture requires an integrated view on a complex interacting system within the soil-plant-atmospheric continuum under continuous change. Aside of the globally observed increase in temperature in almost all viticulture regions for at least four decades, we observe several clear trends at the regional level in the ratio of precipitation to potential evapotranspiration. Additionally the recently published 6th assessment report of the IPCC (The physical science basis) shows case-dependent further expected shifts in climate patterns which will have substantial impacts on the way we will conduct viticulture in the decades to come.Looking beyond climate developments, we observe rising temperatures in the upper soil layers which will have an impact on the distribution of microbial populations, the decay rate of organic matter or the storage capacity for soil organic carbon (SOC). All this influences the emission of greenhouse gases (GHGs) and the viscosity of water in the soil-plant pathway, altering the transport of water. Interactions between micro-organisms in the rhizosphere, the grapevine root system, degradation and fixation processes of SOC are complex and poorly understood but respond to environmental factors (such as increased soil temperatures), the plant material (rootstock for instance), and the cultivation system (for example bio-organic versus conventional, cover crop use versus open tillage). Increasing SOC stocks is discussed as a measure to reduce soil GHG emissions with the potential to improve the balance between GHG emissions and carbon removal from the atmosphere. Yet it is difficult to deduct the impact of climatic changes and cultivation practices on patterns of carbon storage or losses from soils. This paper presents a first attempt to quantify these potential impacts on SOC for a vineyard location using the RothC-model (Coleman and Jenkinson, 2005) in combination with the Geisenheim long-term (> 100-year) soil temperature record and climate predictions by the STAR II-model of the Potsdam Institute of Climate Impact using a medium realization run (Orlowsky et al., 2008).It is shown that retaining pruning wood and using a full cover crop yielded a SOC increase of 16.2 t C ha-1 over time. However, CO2 emissions over the simulated time span were only slightly less than C-storage in the soil. It is concluded that cover crops in vineyards helps to achieve CO2-neutrality but additional measures are required to make vineyards a significant C-sink.

» Nonoperative treatment of a lateral patellar dislocation produces favorable functional results, but as high as 35% of individuals experience recurrent dislocations.

» Medial patellofemoral ligament reconstruction is an effective treatment to prevent recurrent dislocations and yield excellent outcomes with a high rate of return to sport.

» Both nonoperative and postoperative rehabilitation should center on resolving pain and edema, restoring motion, and incorporating isolated and multijoint progressive strengthening exercises targeting the hip and knee.

» Prior to return to sports, both functional and isolated knee strength measurements should be used to determine leg symmetry strength and to utilize patient-reported outcome measures to assess the patient’s perceived physical abilities and patellofemoral joint stability.

This study examines how social capital affects the well-being of individuals in Indonesia. Happiness determinants use several aspects of social capital at the same time: trust, information channels, civic participation, especially political participation. In addition, this estimation also takes into account other socio-demographic factors. The researchers found that trust, information channels, and political participation have a significant impact on the well-being of Indonesian. Individual trust and sociable gatherings to leave a child to a close-neighbor within a few hours have a positive effect on the individual’s well-being. By using IFLS data, a logistic model is used to test whether some indicators of social capital affect individual’s well-being. A positive correlation between social capital and happiness may suggest that public policies toward increasing social capital both at the individual and aggregate level may have complementary effects on raising individual’s well-being. It is important to support the government`s efforts in improving the community’s happiness which in turn can encourage development policies` effectiveness.
The Pattern and Possible Formation Mechanisms of Current Crustal Stress in High Asia

—The pattern of current crustal stress in central and southeastern Asia has been reconstructed from earthquake focal mechanisms by inversion using Rebetsky’s method of cataclastic analysis. The inversion provides constraints on principal stress directions, as well as on relative magnitudes of maximum shear and effective isotropic pressure. The crust of the High Asian mountainous province is subject to horizontal extension or shear in plateaus (East and South Pamir and Tibet) and to horizontal compression or shear in mountain ranges. The relatively high horizontal compression in the ranges is apparently due more to denudation and exhumation than to the pressure from the Indian indentor. Denudation and removal of clastic material from the Himalayan slopes has been a key agent that may compensate for the N–S crust shortening in central Tibet and the W–E stretching in eastern Tibet. The current stress field of High Asia has been mainly controlled by vertical buoyancy forces that arise by thickening of lighter crust and detachment of heavier lithosphere.
TRPM7 kinase domain is part of Rac1-SSH2-cofilin complex regulating F-actin in neural system

Impairment in phosphorylation/dephosphorylation (inhibition/activation) of cofilin, an actin filaments (F-actin) severing protein, can result in numerous brain diseases. The α-kinase domain (M7CK) of transient receptor potential melastatin-like 7 (TRPM7) ion channel interacts with diverse signaling molecules regulating different cellular mechanisms. The kinase protects synaptic density, plasticity and learning and memory functions by phosphorylating cofilin, and hence protecting F-actin within spines. However, mechanisms underlying regulation of cofilin activity and/or F-actin by M7CK remain unknown. Using Western blot analysis in brain tissue, we found that knockout of TRPM7 in glutamatergic neurons of mice resulted in reduction in the phosphorylation levels of cofilin and its activator the protein phosphatase slingshot homolog 2 (SSH2). Co-immunoprecipitation experiments showed direct interaction between M7CK, cofilin and SSH2. Kinase enzymatic activity assay showed that both proteins are phosphorylation targets of M7CK. Upstream from this complex, we found that the GTPase Rac1 can also be co-immunoprecipitated. GTPase activity assay showed that M7CK is a phosphorylation target of Rac1. At the functional level, we found that knockdown (in vitro) or knockout (in vivo) of TRPM7 resulted in reduction in phalloidin puncta within neuronal dendritic areas indicating that F-actin is severed in the absence of M7CK. Expression of the kinase domain, but not the ion channel part, rescued phalloidin puncta in neuronal cell cultures following suppression of TRPM7. Our data suggest that the α-kinase domain of TRPM7 is activated by Rac1. Then the kinase protects F-actin by inhibiting cofilin; directly by phosphorylation and indirectly by preventing its dephosphorylation via SSH2-phosphatase.

One of the therapeutic approaches for decreasing postprandial hyperglycemia is to retard absorption of glucose by the inhibition of carbohydrate hydrolyzing enzymes, α-amylase, and α-glucosidases, in the digestive organs. Coffee consumption has been reported to beneficial effects for controlling calorie and cardiovascular diseases, however, the clear efficacy and mode of action are yet to be proved well. Therefore, in this study we evaluated in- vitro rat intestinal α-glucosidases and porcine α-amylase inhibitory activities as well as in vivo (Sprague-Dawley rat model) blood glucose lowering effects of selected coffee extracts. The water extracted Sumatra coffee (SWE) showed strong α-glucosidase inhibitory activity (IC50, 4.39 mg/mL) in a dose-dependent manner followed by Ethiopian water extract (EWE) (IC50, 4.97) and Guatemala water extract (GWE) (IC50, 5.19). Excepted for GWE all the coffee types significantly reduced the plasma glucose level at 0.5 hour after oral intake (0.5 g/kg-body weight) in sucrose and starch-loaded SD rats. In sucrose loading test SWE (p < 0.001) and EWE (p < 0.05) had significantly postprandial blood glucose reduction effect, when compared to control. The maximum blood glucose levels (Cmax) of EWE administration group were decreased by about 18% (from 222.3 ± 16.0 to 182.5 ± 15.4, p < 0.01) and 19% (from 236.2 ± 25.1 to 191.3 ± 13.2 hr·mg/dL, p < 0.01) in sucrose and starch loading tests, respectively. These results indicate that selected coffee extract may improve exaggerated postprandial spikes in blood glucose via inhibition of intestinal sucrase and thus delays carbohydrate absorption. These in vitro and in vivo studies therefore could provide the biochemical rationale for the benefit of coffee-based dietary supplement and the basis for further clinical study.
