Design of a Compact Dual-Frequency Microstrip Antenna using DGS Structure for Millimeter-Wave Applications
Authors: Hesham Emara  , Sherif K. El Dyasti  , Hussein Hamed Ghouz  , Mohamed Fathy Abo Sree
Published: December 2022

In this paper, a Millimeter-wave (MMW) antenna has been proposed for a current and future wireless application. The proposed model has two resonances at 30.5 GHz and 52.4 GHz. The proposed model has been designed and optimized using a commercial electromagnetic simulator (CST-Studio) and focused on attaining a return loss rate that is lower than -10 dB. The proposed MMW models are built on a small thick Rogers Substrate (RT-5880) with h = 0.508 mm for the thickness, relative permittivity of εr = 2.2, and tanδ = 0.0009 for the loss tangent, while the substrate has a width w_s equal to 6 mm and a length l_s equal to 6 mm. The design process of the model came at three steps, the first step after mathematical calculations has an output of model which has feeding port of 50 ohm with a feedline base length l_b of 0.5 mm and a feedline length l_f of 3 mm, the second step was by using the tapering techniques for enhancing matched impedance after initial calculations to have a length of tapering l_t equal to 1.8 mm, then finally extracting four corner slots to the patch for creating the final proposed model. The previous design process is to assure reliability, mobility, and high efficiency for the proposed antenna. The advantages of this model are the small size, low profile, low fabrication cost, and straightforward design structure. The proposed design can be employed for a variety of Millimeter-wave applications like wireless personal area network (WPAN) and 5G application in some countries like Colombia and Mexico. The proposed model has a moderate gain of 3 dBi to 7 dBi at resonance frequencies of 30.5 GHz and 52.4 GHz, which is one of the unique characteristics of the proposed antenna. The impedance bandwidth is between 28.7 Ghz and 32.6 GHz, which is equal 3.9 GHz, and 49.7 GHz to 56.2 GHz, which is equal to 6.5 GHz respectively for the proposed model, and satisfying efficiency of about 75% and 87% as calculated by CST -Studio, and a VSWR is equal to 1, All of these positive results are more than enough to satisfy the needs of millimeter-wave wireless applications.
Experimental Investigation of the Power Storage System for Savonius Turbines in Wind and Water
Authors: Noorfazreena Kamaruddin  , Muhd Syukri Mohd Shamsuddin
Published: December 2022

The Savonius turbine is practical in generating off-grid electrical power for hydrokinetic applications due to its simple design, particularly for small rivers in rural areas. However, despite many studies on methods to improve turbine performance, the electrical aspect of the turbine system is rarely discussed. Therefore, the present study aims to evaluate the performance of a simple and affordable power storage system using a conventional 2-bladed Savonius turbine. The experiment was conducted in a wind tunnel and a water channel with flow speeds of 6 m/s and 0.33 m/s, respectively, corresponding to a Reynolds number of 62700. A power coefficient of 0.09 was discovered for the wind experiment and 0.11 for the water. The total amount of energy extracted from the water was 60% less than from the wind due to the lower available power. It was observed that the tip speed ratio decreases over the charging period due to the constant current and voltage of the Lithium-Ion batteries. This will allow for a fluctuation in the amount of required current and consequently affect the torque needed to spin the generator. The findings confirmed the functionality of the electrical storage system and contributed to the low manufacturing and maintenance cost of the hydrokinetic turbines.

The Industry Revolution 4.0 (IR.4.0) presents a significant impact on work and lifestyle of most people in Malaysia especially in the banking industry. Industries that are adapting to advance technology such as VR (virtual reality), Internet of Things (IoT), cloud computing, data analytics, artificial intelligence and machine learning will bear changes through physical, digital and biological aspects. The banking industry will need to go through with these three aspects of transformation as its need to be relevant and quickly acquainted to serve their new customer demands besides protecting against risks in cybersecurity, fraud and money loundering in the financial transactions. In order for these banks to stay relevant, both employees and management must be able to bear the changes. To ensure the success in embracing the change, it is suggested in this paper that banks must use a new model of leadership to steer the institutions direction towards the right path and accelerate its transformation. There are four pillars comprises of disruptive driver, human touch, sense of urgency and continuous learning that will constitute the new leadership model called “Leadership 4.0” suggested to banks that will be discussed in this paper.

Published: December 2022

Recent advances in information and communication technology (ICT) have allowed humans to accomplish various tasks more effectively. This also applies to the quality of education, research, and development. For this reason, as one of the countries striving to improve the education system quality, Laos aims to leverage the ICT. As the empirical data on the ICT tools needed to achieve this goal in Laos is limited, this gap in extant knowledge has motivated the present study. Its aim is to examine the views of Laotian academics on the ICT tools and platforms needed, level of ICT usage, and required ICT training. The data for this quantitative study was obtained through a survey involving 11 participants who are directly involved in Building Research Building Social Research Capacities in Higher Education Institutions in Lao PDR and Malaysia (BRECIL) under the ERASMUS project. Subsequent analyses revealed that SPSS, Survey Monkey, Google Scholar, and Grammarly are among the tools academics need the most to support them in research. They also require plagiarism and grammar checking, dissemination and networking, and analysis and interpretation platforms. Most of the respondents also indicated the need for training on how to use ICT tools for analyzing research data. These findings can be used by the educational decision makers when formulating their strategies for introducing ICT tools and organizing training for Laotian academics on research and development.

Authors: Ayuningtyas Dumilah , Agustin Rulliana , Prasetyo Rini , Febrianti Theresa , Ulibasa Esther , Barinda Sandra
Published: December 2022

BACKGROUND: In 2020, TB patients in Indonesia reached 8.5% of the total number of TB patients globally, as the country with the second-highest TB cases. Depok is the city in the West Java region that has experienced an increase in TB cases. The existence of tuberculosis-friendly villages will reduce the stigmatization of tuberculosis (TB) patients and increase treatment compliance.

AIM: This study aims to analyze various aspects of Depok City’s readiness to develop TB-friendly village governance –– including government commitment, infrastructure, resources, and organizational culture –– within the scope of academic, business, community, government, and media (ABCGM)’s role or penta-helix.

METHODS: The initial stage of preparation involved conducting a literature review. This research employed an online survey of 230 respondents and 40 TB patients using a quantitative approach. The qualitative approach involved 15 stakeholders through interviews, discussions, and a website-based search.

RESULTS: Overall, the respondents were well-informed about TB, but attitudes (50.9%) and behavior (41.3%) regarding TB prevention need improvement. The government budget is adequate, but coordination is lacking between stakeholders and community involvement.

CONCLUSION: Depok City is not yet ready to develop TB-friendly villages in terms of human resources and organizational aspects. It is necessary to improve communication, information, and education regarding TB prevention and establish leadership policies as a legal basis to strengthen the governance and management of TB-friendly villages. Moreover, community involvement is an essential pillar of developing these villages.
Further interceptions of the Neotropical fungus gnat Sciophila fractinervis Edwards, 1940 (Diptera, Mycetophilidae) in Britain with comments and observations on its biology and spread
Authors: Deady Rob , Delaney Mark , Jones Eleanor , Chandler Peter
Published: December 2022

From 2020 onwards, several specimens of the Neotropical fungus gnatSciophila fractinervis(Edwards, 1940) have been intercepted by Fera Science Ltd. on or near plant material in the United Kingdom originating from nurseries and glasshouses at four separate locations: Preston, Lancashire; Chichester, West Sussex; East Riding of Yorkshire; and Middlesbrough, North Yorkshire, as well as a single interception from the Netherlands. Gnat interceptions were associated with a wide range of plant species:Ficus benjamina,Ficus elastica, Dracaena reflexa var. angustifolia,Origanum vulgare,Rosmarinus officinalis,Thymus vulgaris,Impatiens hawkeri(ImpatiensNew Guinea hybrids),Chrysanthemum, as well asFragaria vesca(var.Lusa). The species does not appear to be doing any damage to affected plants with growing conditions likely promoting multiplication under protection. The larvae likely feed on spores (generally saprophytic) adhering to webs they erect on the soil and around the base of plants with spores likely originating from the growing medium and plants. Their spread is likely facilitated by movement of the growing medium or plant material where pupae are suspended in the lower stem or leaf axils.

An account of the various interceptions is provided, as well as images of the different life-stages with a brief discussion ofSciophila cincticornisEdwards, 1940, its relationship withSciophila fractinervisand further evidence of instability in vein R2+3in theSciophilagenus.
Explore Adverse Drug Reactions (ADRs) reporting by clinical and community pharmacists in Duhok, Kurdistan region- Iraq: hampered and perspective
Authors: Allela Omer
Published: December 2022

Background: Pharmacovigilance systems are crucial for monitoring, ensuring the safe use of medications, and reducing the frequency of adverse drug reactions (ADRs). They also raise awareness of the importance of reporting ADRs to healthcare systems.

Aim: Explore the hampered and perspective held by Duhok pharmacists, particularly those employed in hospitals and private pharmacy sectors, about pharmacovigilance and ADR reporting.

Methods: A cross-sectional study was carried out from 20 February to 20 March 2019 using a self-administered questionnaire that had been previously created and modified. The data were examined using SPSS version 20, a statistical application for social software.

Results: The majority of respondents, pharmacists, stated that it is their responsibility to report adverse drug reactions (ADRs), and that drug safety monitoring is crucial (91%). More than 85% of pharmacists agreed that ADRs that result in life-threatening situations and those that result in congenital abnormalities should be reported immediately. The majority of them, however, were unaware of the Iraqi pharmacovigilance system, had never reported any adverse drug reactions, were unable to get reporting forms, and lacked the clinical knowledge required to recognize ADRs.

Conclusion: Underreporting was the main issue identified by the study because the majority of respondents were unable to define the term “pharmacovigilance” correctly, but they were aware of ADRs and displayed a positive attitude toward ADR reporting despite the fact that the majority of them had never reported any ADRs. To raise pharmacists’ knowledge and awareness of the ADR reporting procedure, however, required steps should be made to establish interventional programs.

Published: December 2022

Background/Aims: This study evaluated the long-term cardiovascular complications among Korean patients with hypertension and compared them with that of controls without hypertension.Methods: The Korean Hypertension Cohort (KHC) enrolled 11,043 patients with hypertension and followed them for more than 10 years. Age- and sex-matched controls without hypertension were enrolled at a 1:10 ratio. We compared the incidence of cardiovascular events and death among patients and controls without hypertension.Results: The mean age was 59 years, and 34.8% and 16.5% of the patients belonged to the high and moderate cardiovascular risk groups, respectively. During the 10-year follow-up, 1,591 cardiovascular events (14.4%) with 588 deaths (5.3%) occurred among patients with hypertension and 7,635 cardiovascular events (6.9%) with 4,826 deaths (4.4%) occurred among controls. Even the low-risk population with hypertension showed a higher cardiovascular event rate than the population without hypertension. Although blood pressure measurements in the clinic showed remarkable inaccuracy compared with those measured in the national health examinations, systolic blood pressure (SBP) ≥ 150 mmHg was significantly associated with a higher risk of cardiovascular events.Conclusions: This long-term follow-up study confirmed the cardiovascular event rates among Korean hypertensive patients were substantial, reaching 15% in 10 years. SBP levels ≥ 150 mmHg were highly associated with occurrence of cardiovascular event rates.
Relier intervention sociale et recherche : pratiques, postures et enjeux du travail collaboratif

Published: December 2022

Construit dans le prolongement d’une recherche menée à Lille par une équipe réunissant des acteurs de l’intervention sociale et des chercheurs en sociologie, cet article s’intéresse aux dynamiques de construction de connaissances qui se développent dans les espaces au sein desquels se rencontrent Intervention sociale et Recherche. Quel sens les acteurs impliqués donnent-ils au trait d’union qui relie recherche et action dans le champ de l’intervention sociale ? Quelles sont les logiques qui peuvent faire émerger ce souci du travail ensemble autrement – c’est-à-dire en plaçant le dialogue entre recherche et action au centre de nouvelles coopérations ? Considérant de quelle manière le décloisonnement des « mondes » conduit inévitablement à un déplacement, cet article souligne la centralité de la rencontre sociale dans cette recherche qui se fabrique ensemble. Notre proposition s’appuie sur un travail réflexif visant à analyser le processus de construction et les effets de cette pratique collaborative. Celle-ci invite à penser ces espaces intermédiaires comme des espaces éphémères, communs, sources de savoirs et d’expérimentation, mais aussi porteurs de dynamiques mobilisatrices, démocratiques et solidaires.

Exercise induced muscle damage and repeated bout effect: an update for last 10 years and future perspectives
Authors: Rai A. , Bhati P. , Anand P.
Published: December 2022

Exercise-induced muscle damage (EIMD) and repeated bout effect (RBE) are widely researched across various populations. EIMD is the muscle damage occurring after one bout of unaccustomed exercise while RBE is the attenuation of the same muscle damage in subsequent second bout. RBE seems to have significant implications for exercise prescription. Despite existence of vast literature, there is lack of clarity on the effects of EIMD and RBE in a healthy population. The purpose of this study is to review the literature on EIMD and RBE in healthy participants published during the last 10 years. The search of major databases (including Scopus, Google Scholar and PubMed) was conducted using specific keywords ‘Exercise induced muscle damage’, ‘Repeated bout effect’, ‘Healthy participants’ ‘Pre-conditioning’, ‘Eccentric exercise’. Studies published from 2011 onwards which included EIMD and RBE assessment in healthy participants were included in this review. Database searching revealed a total of 38 studies on EIMD and RBE in healthy participants. Three major themes of papers were identified that focused on EIMD and RBE along with (1) age related differences, (2) sex-based differences, and (3) response in athletes. Findings of this comprehensive review suggests that both EIMD and RBE are age, and sex specific. Delayed onset muscle soreness played a major role in both EIMD and RBE in all the population types. Female participants are less susceptible to EIMD as compared to age-matched male counterparts. Moreover, both EIMD and RBE are more elicited in middle aged and younger adults as compared to children and older adults while the magnitude of RBE turns out to be minimal in trained individuals due to persisting adaptations.

Research on cell detection method for microfluidic single cell dispensing
Authors: Cai Junjing , Wang Qiwei , Wang Ce , Deng Yu
Published: December 2022

Single cell dispensing techniques mainly include limiting dilution, fluorescent-activated cell sorting (FACS) and microfluidic approaches. Limiting dilution process is complicated by statistical analysis of clonally derived cell lines. Flow cytometry and conventional microfluidic chip methods utilize excitation fluorescence signals for detection, potentially causing a non-negligible effect on cell activity. In this paper, we implement a nearly non-destructive single-cell dispensing method based on object detection algorithm. To realize single cell detection, we have built automated image acquisition system and then employed PP-YOLO neural network model as detection framework. Through architecture comparison and parameter optimization, we select ResNet-18vd as backbone for feature extraction. We train and evaluate the flow cell detection model on train and test set consisting of 4076 and 453 annotated images respectively. Experiments show that the model inference an image of 320 × 320 pixels at least 0.9 ms with the precision of 98.6% on a NVidia A100 GPU, achieving a good balance of detection speed and accuracy.
Asymmetrical resource competition in aquatic producers: Constant cell quota versus variable cell quota
Authors: Yan Yawen , Wang Hongyue , Chang Xiaoyuan , Zhang Jimin
Published: December 2022

In a shallow aquatic environment, a mathematical model with variable cell quota is proposed to characterize asymmetric resource competition for light and nutrients among aquatic producers. We investigate the dynamics of asymmetric competition models with constant and variable cell quotas and obtain the basic ecological reproductive indexes for aquatic producer invasions. The similarities and differences between the two types of cell quotas for dynamical properties and influences on asymmetric resource competition are explored through theoretical and numerical analysis. These results contribute to further revealing the role of constant and variable cell quotas in aquatic ecosystems.
Assessment of the breeding system in the Algerian narrow coastal endemism Anacyclus linearilobus (Anthemideae, Asteraceae)
Authors: Sánchez-Albert Adrián , Torices Rubén , Kaid-Harche Meriem , Álvarez Inés
Published: December 2022

The breeding system of Anacyclus linearilobus, an annual and endemic species restricted to dune ecosystems of the Algerian coast were assessed through the effect of self-fertilization and intra- and inter-population artificial crosses on the probability of producing viable seeds in 20 individuals from two populations in a common garden. The breeding system was determined for each individual by the self-incompatibility index (ISI). These results were compared with those published for other species of the genus, A. clavatus, A. homogamos and A. valentinus. Results of experimental crosses showed that there was high variation in the female reproductive success between individuals of A. linearilobus, like that found in its sister species, A. valentinus. Unlike the other species in the genus that are self-incompatible, A. linearilobus showed a mixed mating system, with a majority of self-incompatible individuals, others partially self-incompatible and some self-compatible. We argue that this strategy may be related to reproductive assurance in this endemic, annual species whose effective population size has been reduced probably due to individual mating incompatibilities.
A reconceptualization of the interactions between spawning and growth in bony fish
Authors: Pauly Daniel , Liang Cui
Published: December 2022

Among fishery biologists and even ichthyologists, maturation and spawning of fish are viewed as processes that use “energy” that would otherwise be applied to somatic growth, which is supposed to explain why post-maturity growth in length tends to decline. This widespread conceptualization may be called the “reproductive drain hypothesis” (RDH). However, when growth is correctly viewed as involving body mass, and is thus expressed in weight, post-maturity turns out (in iteroparous bony fish whose maximum length exceeds 10 cm) to accelerate after first maturity, despite its energy cost. This, and other common observations flatly contradict the RDH, and the time has come to withdraw this hypothesis. As a contribution towards this task, we propose an alternative reconceptualization of fish spawning consistent with what is known about fish biology.
Expansion and contraction of the Engraulis ringens spawning area in northern Chile
Authors: Moreno Paola , Claramunt Gabriel
Published: December 2022

Many studies have considered the temporal patterns of reproduction of Engraulis ringens, but little attention has been given to the spatial patterns of reproduction (spawning areas), which have shown great variability in both location (geographical position) and extent (the area covered by positive stations), without a satisfactory explanation. Along the Chilean coast, the daily egg production method (DEPM) has been used for several years to estimate spawning biomass in the northern Chile E. ringens population, with 24 surveys being carried out from 1992 to 2020. The most fluctuating parameters estimated in the DEPM have been the location and extent of the spawning area and the average female weight. In the last few years the eggs were distributed near the coast, whereas in the first few years they showed a more oceanic distribution. The average female weight has fallen from 30 g in the 1990s to 11 g in the last few years. In the present study, we analysed the relationship of the location and extent of spawning areas with female size and abundancy in E. ringens from northern Chile. According to the results, periods of high abundancy of eggs are positively correlated with larger females that spawn in more oceanic zones and to the south, expanding the spatial egg distribution and increasing the egg density. By contrast, in years with low abundance of eggs, the spawning was located north and towards the coast, with a smaller spawning area and smaller female size.
Unified cosmological scale versus Planck scale: As above, so below!
Authors: Haug Espen Gaarder
Published: December 2022

We will demonstrate that the mass (equivalent mass) of the observable universe divided by the universe radius is exactly identical to the Planck mass divided by the Planck length. This only holds true in the Haug universe model that takes into account Lorentz’s relativistic mass, while in the Friedmann model of the universe, the critical mass of the universe divided by the Hubble radius is exactly equal tomp/(2lp). Furthermore, in a recently suggested quantum gravity model, the mass of the universe divided by the radius of the universe is exactly identical tomp/lp; that is, the Planck mass divided by the Planck length. This is much more than just a speculative approximation, for the findings are consistent with a new unified quantum gravity theory that links the cosmological scale directly to the Planck scale.

Hanham Hall (Bristol) and Derwenthorpe (York) are two newly built eco-villages, and BedZED (London) is a famous environmentally friendly housing development project built more than 10 years ago. From energy-saving technology, ecological landscape, building combination and open space design, and architectural appearance and space design, this chapter analyzes these aspects of these eco-villages' features and advantages. It then sums up how the eco-village or eco-residence will benefit from good architectural design (indoor) and excellent community design (outdoor). It emphasizes the importance of the architectural design, economic, and ecological technology application balance. Furthermore, the article pointed out the eco-community's requirements and features: social, environmental, ecological, livable, and sustainable.

Earth-based materials (EBM) provides a valuable avenue for improving thermal comfort, energy consumption, indoor air quality and humidity regulation. However, in the literature, very few studies have addressed hygrometric characteristics of shell huts in EBM from the far north region of Cameroon. The use EBM is hampered by the non-availability of databases related to their intrinsic properties and through unfamiliarity of their behavior over time. In the meantime, these shell huts in EBM are known for their moisture which regulates properties and thus contributes to the comfort of their occupants. This study aims to determine experimentally the adsorption/desorption isotherms at 30, 40 and 50 °C of the straw earth material carried out by the static gravimetric method for eight saturated salt solutions (LiCl, MgCl2, Mg(NO3)2, NaBr, IK, NaCl, KCl and K2SO4). The experimental curves obtained for absorption / desorption show that for a given water activity, the equilibrium water content Weq increases inversely with temperature (i.e. decreases with increasing temperature, and vice versa). In addition, the absorption curve does not overlap with the desorption curve. As a result, these shell huts in EBM display interesting humidity regulation characteristics.

The formability of sheet-metal with a folding-bottom circular hollow tube has been studied both by numerical simulation and experiment. A mesh-convergence analysis has been carried out to determine an optimum element size for purposes of numerical simulation. The geometry and dimension of the dies and of the punch are designed to simulate the multi-stage deep drawing operation to take place. During the deep drawing operation, the strains of the sheet blank are always located in the second quadrant of the forming limit diagrams, and it continuously moves in a linear state to the left side of the diagram. At the final stage, the tube is drawn to a certain height without evidence of fracture. In order to obtain a quality product, an optimization of input parameters for the deep drawing operation is conducted using Taguchi method. Finally, a validation test is also employed to demonstrate the accuracy of forming processes. The result reveals sufficient agreement in both geometry and dimension between simulated and actual tubes to meet a good quality standard.

Published: December 2022

In the present study, a solid biofuel based on Olive Pomace Waste (OPW) is manufactured in order to estimate the energy for heating water. A mechanical hydraulic press is constructed in order to create the block of OPW biofuel. To proceed, the standard form is burned to heat water in a tank where a thermocouple is placed to estimate the heating energy created by OPW blocks. Then, the standard OPW blocks are compared experimentally with other mixed biofuel blocks such as, waste Beeswax, oak charcoal, dry olive leaf and waste wood sawdust. It is shown that the standard OPW blocks could increase the temperature of 3 Liters of water to 34 °C whereas with the modified OPW mixed with other constituents temperatures up to 65 °C can be reached.

Published: December 2022

Contact lenses are being used by more than 125 million people around the world for ophthalmic treatments. There has been a recent surge in interest in researching and developing new materials for contact lenses (CLs). With the advancement of associated biomaterials, such as drug delivery, these materials will continue to grow in importance in the future. If you're looking to buy contact lenses, you'll most likely find them made out of polymer or silicone hydrogel. To meet the ever-increasing needs for contact lenses and the ever-increasing number of contact lens users, this work aims to study the effect of adding aloe Vera gel to contact lenses, antibacterial behavior, surface texture, and wettability. Results show the addition of aloe Vera natural materials to rigid PMMA contact lenses aid to promote the performance of contact lenses by changing the internal structure of PMMA, especially when using (0.1%, 0.2%, and 0.3%) of aloe Vera due to the increasing in OH content as well as the increasing in the uniformity of microstructure. addition of (0.4% and 0.5 %) of aloe Vera make a reverse effect on the structure due to the saturation of PMMA chain with OH leading to destroying the connections between bonds, therefore, weakening PMMA lenses also using aloe Vera gel act to soften the lenses by increasing the OH content in PMMA structure lead to improving the lens wettability at about (0.2-0.3) % after these percentage large drop in whole properties will occur. Keywords: Rigid contact lens, PMMA, natural materials, Aloe Vera, OH content.

Background

Conventional dosage forms of oral hypoglycemic drugs, including gliclazide (GLZ), may have a number of limitations, reducing their bioavailability. Thus, efforts are directed to design novel modified-release (MR) dosage forms for these drugs. The possible role of orally administered GLZ-MR multiparticulates in the treatment of hyperglycemia as well as improvement of impaired wound healing associated with type 2 diabetes mellitus was investigated.

Objective

This study aimed to evaluate the pharmacodynamics (PD) of GLZ-MR multiparticulate system against Diamicron MR tablets in nondiabetic (healthy) and streptozotocin-induced diabetic rats, by measuring blood glucose levels. For the first time, the hypothetical wound-healing capabilities of multiple doses of both treatments in diabetic rats were also studied by evaluating the wound diameter and histology.

Materials and methods

Novel cross-linked freeze-dried GLZ-alginate-gelatin beads were prepared. Two GLZ treatments at 4 mg/kg [test (T, MR beads) and reference (R, Diamicron MR 30 mg)] were administered to rats. A single-dose PD study was carried out on both healthy and diabetic rats, whereas the multiple-dose study was evaluated in diabetic rats. A single-dose pharmacokinetics (PK) study was conducted for assessment of the PK-PD relationship in healthy rats.

Results and conclusion

The single-dose study on nondiabetic rats showed that T beads exhibited a greater magnitude of blood glucose level reduction, with 1.5-fold increase in Cmax, compared with R. A direct linear relationship with high correlation was detected between GLZ glucose-lowering effect and its PK parameters, only for T beads. Multiple dosing of T beads was more efficient than R in managing hyperglycemia of wounded diabetic rats. T beads allowed almost complete wound closure, after multiple dosing for 17 days. The proposed GLZ beads could provide a promising therapeutic prospect for managing hyperglycemia as well as resolving impairment of wound healing associated with diabetes.
Yoga as a complementary and alternative therapy for cardiopulmonary functions
Authors: Rathore Vipin , Yadav Nidheesh
Published: December 2022

Complementary and alternatiASve therapy is a rapidly growing area in the biomedical sciences, in which Yoga therapy has arisen at the frontlines of holistic medical care and is perceived as a form of mind-body practise because of its long history of connecting physical, mental, and spiritual well-being with the coalescence of physical postures (asana), breathing exercises (pranayama), and meditation (dhyana). This study aims to review the emerging evidence assessing the physiologic and clinical effects of Yoga on cardiopulmonary functions. The authors searched the PubMed (Medline) and Science Direct databases and the Google Scholar search engine, as well as a reference list of related articles, for literature related to the effect of yoga on pulmonary function, cardiovascular function, and cardiopulmonary functions from 2000 to 2021. Yoga has been shown to have favorable effects on the various parameters of cardiovascular and pulmonary functions. Yoga has emerged as a beneficial lifestyle intervention that can be incorporated into cardiovascular and pulmonary disease management methods. Although numerous researchers have reported the clinical benefits of Yoga in reducing cardiopulmonary-related events, morbidity, and mortality, the evidence supporting these conclusions is somewhat limited, thereby stressing the requirement for large, well-designed randomised trials that limit bias and methodological drawbacks.
