Published: June 2022

This paper covers the forms of cyberbullying prevention measures in adolescents. Cyberbullying is sometimes still underestimated by some people, even though the impact of this cyberbullying will have a huge impact on teenagers. This study aims to describe several forms of cyberbullying prevention measures at the age of teenagers. The object of this research is the parents of teenage children. This study uses a quantitative method approach that will use an inductive mindset to conclude. Then, using a questionnaire for data collection methods. From the data collected through filling out the google form, it can be concluded that the form of parental action taken to prevent cyberbullying behavior is by providing education about social media to children, often communicating with children, and emotionally supporting children such as giving love. to children, applying time restrictions on the use of gadgets and in using social media to children, conducting social media checks. As well as telling children that they have to sort out what I should post on social media.

School tasks are responsibilities that must be done and completed for every student. However, there are some cases where students are late in submitting the tasks, while the others do not even submit them at all. The behavior of delaying the responsibility is called procrastination, and if the responsibility is in academic things, then it is called academic procrastination. Academic procrastination behavior can have an impact on students' grades. Guidance and counseling teachers can help counselees in solving academic procrastination problems by using group counseling with bibliotherapy techniques. The subjects of this study are two students who have procrastination behavior and one guidance and counseling teacher. This study use qualitative research method with descriptive approach. This study aims to determine the implementation of group counseling using bibliotherapy techniques on academic procrastination of ninth-grade junior high school students. Guidance and counseling teachers can use group counseling with bibliotherapy and the solve strategy to reduce academic procrastination behavior for ninth-grade junior high school students.

Aberrant autophagy and skewed inflammatory and tolerogenic functions in STAT1 gain-of-function dendritic cells
Authors: Parackova Zuzana , Zentsová Irena , Vrabcova Petra , Šedivá Anna , Bloomfield Marketa
Published: June 2022

Signal transducer and activator of transcription 1 (STAT1)
gain-of-function (GOF) mutations underlie an inborn error of immunity
called chronic mucocutaneous candidiasis. Beyond the fungal
susceptibility, attributed to Th17 failure, over half of the reported
patients suffer from autoimmune manifestations, the mechanism of which
has not been explained yet. Dendritic cells (DCs) have been implicated
in the pathogenesis of various autoimmune disorders, however, to date
they have not been studied in STAT1 GOF CMC. We hypothesized that the
STAT1 mutations would affect DCs’ properties and alter their
inflammatory and tolerogenic functions. To test the hypothesis, we
generated monocyte-derived DCs (moDCs) and tolerogenic DCs (tDCs) from
freshly isolated STAT1 GOF patients’ monocytes cultivated in the
presence of IL-4 and GM-CSF (moDCs), and tolerogenic factors vitamin D2
and dexamethasone (tDCs). Functional and signaling studies, co-culture
experiments and RNA sequencing demonstrated that STAT1 GOF DCs were
profoundly altered in their phenotype and functions, characterized by
defective autophagy, proinflammatory skew and loss of tolerogenic
functions. The results suggested that DCs play an important role in the
immune dysregulation in STAT1 GOF CMC and may contribute to the
disease-associated autoimmune manifestations via alteration in various
cellular mechanism, including autophagic processes.
Multiple Solutions for a Kirchhoff-type Fractional Coupled Problem with p-Laplacian

Published: June 2022

In this paper, we look at a class of two-parameter coupled
Kirchhoff-type fractional differential equations. Two differentiated
methods are used to prove the existence of two solutions to the
equation. The fundamental difference between the two methods is that the
first provides asymptotic conditions for the non-linear terms on the
right-hand side of the equation, while the second provides algebraic
conditions; both methods combine substantial A-R conditions.

Published: June 2022

The coastline of Sub-Saharan Africa hosts highly diverse fish
communities of high conservation value, which are also key resources for
local livelihoods. However, many costal ecosystems are threatened by
overexploitation and their conservation state is frequently unknown due
to limited monitoring budgets and challenges associated with their vast
spatial extents. Here, we evaluated the potential of citizen
science-based eDNA surveys to alleviate such chronic data deficiencies
and assessed fish communities in Mozambique using two 12S metabarcoding
primer sets. Samples were either collected by scientific personnel or
trained local community members and results from the two metabarcoding
primer sets were combined using a newly created data merging approach.
Irrespective of the background of sampling personnel, a high average
fish species richness was recorded (38±20 OTUs sample-1). Individual
sections of the coastline largely differed in the occurrence of
threatened and commercially important species, highlighting the need for
regionally differentiated management strategies. A detailed comparison
of the two applied primer sets revealed an important trade-off in primer
choice with MiFish primers amplifying a higher number of species but
Riaz primers performing better in the detection of threatened fish
species. This trade-off could be partly resolved by applying our
data-merging approach, which has the potential to provide a more robust
baseline-data for decision-making processes. Overall, our study provides
encouraging results but also highlights that eDNA-based monitoring will
require further improvements of e.g., reference databases and local
analytical infrastructure to facilitate routine applications in
Sub-Saharan Africa.
Heidegger on aesthetic emotions: Stimmung and the artwork experience
Authors: Popovic Una
Published: June 2022

This paper is about Heidegger?s understanding of the artwork experience, with
regard to the notion of Stimmung, which is to replace traditional conception
of aesthetic emotion, that is, of aesthetic experience. Namely, Heidegger
disregards modern discourse on cognitive powers of the soul, and so he also
abandons the conception of aesthetic emotions. His critique of modern
representational thinking leads to the notion of Stimmung, which, if related
to the work of art, replaces the notion of aesthetic emotions, but also goes
a step further. The notion of Stimmung in Heidegger?s thought is equally
related to the production and reception of artworks. However, with regard to
the reception, it implies the necessity of radical transformation of the way
we feel and understand being, provoked by art. Finally, this notion is also
related to the dialogue of thinking and poeticizing, since Heidegger
ascribes it both to philosophy and art.
Contemporary art, affective turn and emotions
Authors: Ilic Vlatko
Published: June 2022

Due to the so-called Affective Turn, which is according to a number of
scholars shaping present cross-disciplinary studies of various phenomena,
art included, emotions are coming into focus of many different theoretical
orientations. Among the authors concerned with issues of emotions, Sara
Ahmed?s discourse on affective economies, and her understanding of emotions
as practices that produce surfaces and borders that allow the collective and
the individual to appear as objects proves to be particularly useful in the
analysis of immaterial artworks. In regard to the leading poetic principles
of contemporary art practices, starting from Bourriaud?s Relational
aesthetics and the insights offered by Sara Ahmed, we will look more closely
into emotions as key notions for understanding the aesthetics experience of
art today.

Authors: Ahmed Manal Ghassan , Ali Faez Hassan
Published: June 2022

The present article proposes an exact algorithm for the single-machine scheduling problem to minimize the sum of total completion times, range of lateness and maximum tardiness on a single machine (1/ /(∑ C_(σ_j + R_L + T_max)), where machine idle time is prohibited. In this paper, one of the multiobjective function problem for single criteria on just one machine is being studied. To obtain the optimal solution for the suggested problem, we propose to use Branch and Bound method (BAB) depending upon some dominance rules. This exact method used new technique to obtain three upper bounds (UB) and single lower bound (LB). The proposed BAB method proved its sufficiency by the practical results for n ≤ 15 in a reasonable time. Lastly, we proved a theorem as special case for our problem.

Multimodalidade, sinestesia e multiletramentos: subjetividades para formação de professores de língua inglesa
Authors: Grande Gabriela Claudino
Published: June 2022

Novas tecnologias digitais em contextos educacionais ainda encontram resistência aos letramentos multimodais, se pautando, principalmente, no grafocêntrismo. Neste sentido, e para que mudanças expressivas possam ocorrer, os multiletramentos e o conceito de design, apoiados pela gramática visual, são caminhos possíveis para o desenvolvimento de inovações inteligentes e criativas na construção de conhecimentos. Partindo de uma costura teórico-metodológica dos multiletramentos e da perspectiva sociossemiótica da multimodalidade, o presente artigo busca refletir ontoepistemologicamente – a partir de análises da apresentação de um trabalho avaliativo sobre o ensino de língua inglesa que ativa letramentos multimodais por meio da sinestesia – sobre a subjetividade e a identidade de um professor-acadêmico em formação no curso de Letras. Para realizar as análises, adotamos os elementos de design na construção de significados, propostos por Kalantzis, Cope e Pinheiro (2020). Tais análises demonstraram como a multimodalidade e a sinestesia propiciam produções de sentidos que levam o discente a refletir sobre sua subjetividade e identidade híbrida, unindo esferas pessoais e profissionais, de um professor gay que utiliza (ou pretende utilizar) os espaços de educação linguística para criação de reflexões e usos de linguagens multimodais e sinestésicas para produções de textos digitais. Adicionalmente, suas identidades pessoal e profissional também podem representar espaços de resistência para educação linguística como instrumento de luta, em oposição ao status hegemônico que essa língua tem desempenhado e principalmente para efeitos de colonização.

Published: June 2022

Microcrystalline cellulose was first extracted from pineapple crown leaf waste which is used very rarely as an alternative material from agricultural residue and then characterized. Microcrystalline cellulose was extracted from this waste through acid hydrolysis with various concentrations. The effect of acidconcentrations with sulfuric acid (H2SO4) on microcrystalline cellulose properties was investigated to determine its potential application as a material. Pineapple crown leaf was hydrolyzed for 2 hours at 45℃ along with various sulfuric acid concentrations (1, 2, and 3 M). The properties of the cellulose were evaluated by Scanning electron microscopy (SEM), Fourier transforms infrared (FTIR) spectroscopy, X-ray diffraction (XRD), and thermogravimetric analysis (TGA). Among all the hydrolysis conditions carried out, the best hydrolysis condition was 3 M sulfuric acid. At this hydrolysis condition, the microcrystalline cellulose presented a rod-like shape, high crystallinity at 83.16%, and have average crystal size of 17.99 nm. The functional group and morphology analysis showed that the resulted product is maintained cellulose I structure and removal of non-cellulosic constituents and the chemical compositions. As for the thermal analysis, the temperature decreased from 177℃ (2 M sulfuric acid) to 149℃ (3 M sulfuric acid) because of the incorporation of sulfate groups after the hydrolysis process. Therefore, microcrystalline cellulose obtained from pineapple crown leaf waste has great potential as reinforcement in the manufacture of composites.

Published: June 2022

Ceiba pentandra (Kapok) is a tropical plant belonging to the Malvales that contain palm oil. Naturally, Pure Plant Oil (PPO) can be used as a renewable energy source that is a promising energy alternative instead of fossil. Somehow, one of the effects of the quality of Pure Plant Oil (PPO) is the presence of unsaturated bonds and the presence of oxygen. The most appropriate method to overcome these problems is hydrodeoxygenation using a batch system autoclave reactor. In the present work, we synthesized of Green Diesel using hydrodeoxygenation and NiMo/γ-Al2O3 catalyst to saturate double bonds and remove oxygen. The yield of pure plant oil was 42.77-74.72% while the yield of green diesel at pressure conditions of 30 and 50 bar and at temperatures of 300, 350 and 400°C produced 76.73 – 94.06%. Then, the best condition for the hydrodeoxygenation reaction for the biggest yield is at a pressure of 50 bar at 350°C. The results of the characterization of gas products using GC-TCD showed the composition of gases H2, O2, CO, CH4, and CO2. Whereas for green diesel liquid products, pure plant oil, and kapok seed oil were analyzed using GC-MS obtained hydrocarbon compounds with interval C10-C20. Quality analysis of kapok seed oil, pure plant oil, and green diesel has been in accordance with quality standards except for FFA and viscosity.

The research aims to evaluate the pollution of Pb and Zn in water, sediment, and Faunus ater samples collected from Krueng Balee (KB) and Kreung Reuleung (KR) Rivers, Aceh, Indonesia. The samples were collected at the upstream, midstream, and downstream of each river and analyzed using Atomic Absorption Spectrophotometry (AAS). The distribution of Pb and Zn pollution was analyzed using Principal Component Analysis (PCA). Our investigation revealed that the presence of Pb and Zn is still safe for water and sediment samples. Nevertheless, Pb and Zn contamination found in F. ater samples had exceeded the national safety limit for food. PCA analysis revealed correlations between samples suggesting the roles of physical and chemical properties of the river in the pollutant retainment. The analysis also indicated the possible antagonism between Pb and Zn accumulation in F. ater which has never been reported previously. We suggest routine monitoring of Pb and Zn concentrations. The role of the surrounding industry in the Pb and Zn pollution should be further studied.

Published: June 2022

The northern waters of Banda Aceh are connected with the Indian Ocean, the Andaman Sea, and the Malacca Strait, thus making the study of water quality parameters in this region is important for enviromental management. In this study, water quality parameters are measured spatially and then continued with assessing the pollution index. The results can be helpful for development planning and coastal pollution mitigation in Banda Aceh. The data was collected from 21 seawater samples from 11 stations representing the water of Banda Aceh on 10-11 September 2019. VanDorn bottles were used to store the seawater samples for laboratory analysis. Several parameters such as temperature, salinity, and pH were measured in situ, while other parameters were tested in the laboratory. Most heavy metal parameters showed values below the minimal and maximal value limit detection of the instrument, indicating a small potential for heavy metal contamination. However, the pollution index (PI) indicates the potential for water pollution dominated by nitrate and phosphate with a value that exceeds the water quality standard. The indications are shown from the high aquaculture and anthropogenic activities around the coast of Banda Aceh.

InlB protein secreted by Listeria monocytogenes controls the pathogen interaction with macrophages
Authors: Chalenko YM , Abdulkadieva MM , Safarova PV , Kalinin EV , Slonova DA , Yermolaeva SA
Published: June 2022

The virulence of gram-positive bacterium Listeria monocytogenes depends on its capacity to infect non-professional phagocytes and proliferate inside them. Listerias monocytogenes captured by mononuclear phagocytic cells during the infectious process are resistant to lysosomal digestion and can proliferate inside macrophages. Internalin B (InlB), one of the key pathogenicity factors of L. monocytogenes, interacts with mammalian receptors c-Met and gC1q-R. For epithelial cells, such interactions with surface receptors promote activation of these receptors and cytoskeletal remodeling, which leads to massive bacterial invasion into nonprofessional phagocytes. For macrophages, by contrast, nothing is known about the role of InlB in their interactions with L. monocytogenes apart from the fact that both receptors are abundantly expressed by macrophages and participate in the development of immune reactions. This study aimed at determination of the potential role of InlB in the interactions between L. monocytogenes and macrophages. We found that 1) InlB expression promoted a significant 3.5-fold increase in the rates of L. monocytogenes capture by macrophages; 2) the 24 h fold increase in bacterial number inside macrophages constituted 182.5 ± 16.7, 96 ± 12 and 13.3 ± 3 for EGDe∆inlB, EGDe and EGDe∆inlB::pInlB strains, respectively; 3) the EGDe∆inlB::pInlB strain, complemented with a plasmid copy of inlB, produced InlB at 3.3fold higher rates than the type strain EGDe. We conclude that InlB negatively affects the survival of listeria inside macrophages. The results enable advanced understanding of the host-pathogen interactions for L. monocytogenes.

Introduction

This study explores the relationship between emotional support, perceived risk and mental health outcomes among health care workers, who faced high rates of burnout and mental distress since the beginning of the COVID­19 pandemic.

Methods

A cross­sectional, multicentred online survey of health care workers in the Greater Toronto Area, Ontario, Canada, during the first wave of the COVID­19 pandemic evaluated coping strategies, confidence in infection control, impact of previous work during the 2003 SARS outbreak and emotional support. Mental health outcomes were assessed using the Generalized Anxiety Disorder scale, the Impact of Event Scale – Revised and the Patient Health Questionnaire (PHQ­9).

Results

Of 3852 participants, 8.2% sought professional mental health services while 77.3% received emotional support from family, 74.0% from friends and 70.3% from colleagues. Those who felt unsupported in their work had higher odds ratios of experiencing moderate and severe symptoms of anxiety (odds ratio [OR] = 2.23; 95% confidence interval [CI]: 1.84–2.69), PTSD (OR = 1.88; 95% CI: 1.58–2.25) and depression (OR = 1.88; 95% CI: 1.57–2.25). Nearly 40% were afraid of telling family about the risks they were exposed to at work. Those who were able to share this information demonstrated lower risk of anxiety (OR = 0.58; 95% CI: 0.48–0.69), PTSD (OR = 0.48; 95% CI: 0.41–0.56) and depression (OR = 0.55; 95% CI: 0.47–0.65).

Conclusion

Informal sources of support, including family, friends and colleagues, play an important role in mitigating distress and should be encouraged and utilized more by health care workers.

Authors: Rodrigues Jondison Cardoso , Campos Raione Lima , Santana José Raimundo
Published: June 2022

Latin America has a long history of extractive and exploitative territorial activities, dating back to the colonial era. However, in the last decade there has been a steep increase in these activities, and in socio-environmental conflicts, in Latin America. There are indications of the links between the exploitation of natural resources and the violation of human rights, which materializes in the Amazon through the increase of expulsions and evictions of families, assassination attempts, murders, illegal imprisonments, intimidation, and threats. The main targets of these crimes are leaders who head the struggle to defend the rights of collectivities to land and territory, the environment, human rights and their multiple cultural and life expressions. The state of Pará (Eastern Amazonia) has appeared in the last decade as one of the states in Brazil with the highest incidence of cases of land conflicts, assassinations, aggression, defamation, and death threats directed against community leaders and environmental defenders. Thus, this article aims to quantify, characterize and reflect on the environmental defenders and community leaders suffering death threats and under legal protection in the state of Pará, Eastern Amazonia (between 2014 and 2020). It also seeks to identify the main activities and sectors that threaten these groups and the reasons behind the intensification of threats in recent years.

This paper presents an iterative method for the unbiased identification of linear Multiple-Input Multiple-Output (MIMO) discrete two-dimensional (2D) systems. The system discussed here has Auto-Regressive Moving-Average model with exogenous inputs (ARMAX model). The proposed algorithm functions on the basis of the traditional Iterative Generalized Least Squares (IGLS) method. In summary, this paper proposes a two-dimensional Multiple-Input Multiple-Output Iterative Generalized Least Squares (2DMIGLS) algorithm to estimate the unknown parameters of the ARMAX model. Finally, simulation results show the efficiency and accuracy of the presented algorithm in estimating the unknown parameters of the model in the presence of colored noise.
Simultaneous shape and mesh quality optimization using pre-shape calculus
Authors: Luft Daniel , Schulz Volker
Published: June 2022

Computational meshes arising from shape optimization routines commonly suffer from decrease of mesh quality or even destruction of the mesh. In this work, we provide an approach to regularize general shape optimization problems to increase both shape and volume mesh quality. For this, we employ pre-shape calculus as established in Luft and Schulz (2021). Existence of regularized solutions is guaranteed. Further, consistency of modified pre-shape gradient systems is established. We present pre-shape gradient system modifications, which permit simultaneous shape optimization with mesh quality improvement. Optimal shapes to the original problem are left invariant under regularization. The computational burden of our approach is limited, since additional solution of possibly larger (non-)linear systems for regularized shape gradients is not necessary. We implement and compare pre-shape gradient regularization approaches for a 2D problem, which is prone to mesh degeneration. As our approach does not depend on the choice of metrics representing shape gradients, we employ and compare several different metrics.

Honeybee venom (HBV) is an important product of beehives, and its benefits for health have been rediscovered by modern medicine. Since HBV has the potential to treat some diseases, its quality and production conditions require a detailed investigation. The objective of this study is to understand how season, harvesting time (day or night), harvesting site of beehives (inside or entrance) and geographic location affects quality through the analysis of apamin, melittin and phospholipase A

(PLA2) content. Each set of six colonies were used to understand the differences in these components when HBV is harvested in the daytime either from the entrance or inside of the hives and nighttime from the inside of the hives. The experiment also investigated seasonal differences as the samples were harvested each month from May to August 2019 in our apiary. Furthermore, the effect of geographic location on quality was examined through the comparison of the data obtained from twenty-seven samples collected by beekeepers using the same device, located in the Turkish cities of Manisa, Muğla, Balıkesir, Düzce and Mersin. The results demonstrated that statistically significant differences in the amounts of analyzed components were not dependent on harvesting time, collection site on the beehives or season. On the other hand, region samples significantly differed in the amounts of all three components, ranging from 1.28% to 3.81% for apamin, 19.51–64.03% for melittin and 7.22%–28.18% for PLA2. However, beekeepers’ improper practices during harvesting and storing might be the most critical parameters that determine the quality of HBV.

Ectothermic organisms including insects are highly vulnerable to climate warming which not only influences their biology, ecology and physiology but also affects their symbiotic gut microbiota. This study determined the impact of ambient (control) and simulated warmer (heating) climatic conditions on the microclimate of brood nest and gut bacterial abundance of two Apis mellifera subspecies i.e. A. mellifera ligustica and A. mellifera sinisxinyuan. For both subspecies, brood nest temperature and relative humidity under the heating treatment were significantly different (p≤0.001) than those under the control treatment. Quantitative PCR data revealed that the abundance of gut bacteria (16S rRNA gene copy numbers) of A. mellifera ligustica and A. mellifera sinisxinyuan larvae was significantly higher (P≤0.05), 1.73 and 5.32 fold higher respectively, during the heating treatment than those in control conditions. Although gut bacterial abundance of A. mellifera ligustica (1.67 × 107 copies g−1 fw) and A. mellifera sinisxinyuan (1.7 × 107 copies g−1 fw) larvae was similar during the control treatment, A. mellifera sinisxinyuan larvae exhibited three times greater gut bacterial abundance than A. mellifera ligustica during the heating treatment. Similarly, adult A. mellifera sinisxinyuan bees harboured significantly greater bacterial abundance during the heating treatment than control. These findings elucidate that climate warming may significantly affect the honeybee colony microclimate and their gut bacterial abundance. However, further studies are needed to better understand how gut microbial community may influence the learning, physiological and behavioural mechanisms of the host bees in a climate warming scenario.

Pollen nutrition is critical for the development and well-being of the honeybee. Previous studies have compared the effect of pollen and carbohydrate-only diet on honeybee physiology. The effect of a monofloral versus polyfloral diet on the African honeybee (Apis mellifera scutellata) is poorly understood. This knowledge is critical as diversity-rich habitats are being altered to less diverse environments through increased urbanization and intensified agricultural activities, particularly in sub-Saharan Africa. Here, we report how lowly diverse (LD) and highly diverse (HD) pollen diets influence honeybee life-history traits and physiology. To achieve this, we fed caged bees with the two pollen diets and tested their effects on the parameters of survival, body weight, pollen consumption, and immune response. HD-fed bees had significantly higher survival and greater pollen consumption than LD-fed bees. However, LD-fed bees were heavier than HD-fed bees. The correlation between body weight gain and pollen consumption was expressed strongly in HD-fed bees than in LD-fed bees. Overall, our findings reveal the benefits that the highly diverse polyfloral diets provide to honeybee workers. This study shows how pollen diversity influences honeybee life-history traits, thus informing the need for conserving the biodiversity of environments for safeguarding the health of honeybees and other pollinators.

Introduction. Aerobic dance (AD) has grown as a popular aerobic exercise treating metabolic diseases. However, its beneficial effects on type 2 diabetes mellitus (T2DM) compared with other types of aerobic exercise have not been known. This study aimed to compare the influence of AD and static cycling (SC) on anthropometric measures, systolic blood pressure (SBP), blood glucose, and total cholesterol.

Material and Methods. The design of this study was a randomized controlled study (RCT). Thirty T2DM subjects were assigned to three groups, i.e. control (C), aerobic dance exercise (AD), and static cycling exercise (SC), ten subjects in each group. AD and SC were performed three times a week for eight weeks. On the follow-up, four subjects were withdrawn. Waist and hip circumference (WC and HC), BMI, and blood pressure (BP) were measured. Blood glucose (fasting (FBG) and 2 hours postprandial (2-h PPBG)) and total cholesterol were checked using a simple, instant blood examination device. A paired t-test, Anova and Tamhane’s T2 post hoc test were applied. Significance was set at p < 0.05.

Results. Student’s t-test showed that post-exercise waist circumference was significantly increased in the control group (92.7 ± 13.5 cm, p = 0.04), while post-exercise FBG and 2-h PPBG were significantly reduced in the SC group (112.5 ± 12.0 mg/dL, p = 0.04 and 155.0 ± 45.3 mg/dL, p = 0.02, respectively). Tamhane’s T2 post hoc indicates that 2-h PPBG in SC was lower than in the case of AD (155.0 ± 45.3 vs 171.3 ± 19.7 mg/dL, p = 0.04) and SC vs control (155.0 ± 45.3 vs 183.0 ± 24.1 mg/dL, p = 0.02). Systolic was significantly reduced in SC compared to the control group (126.9 ± 7.5 vs. 143.3 ± 17.5 mmHg, p = 0.04). The magnitude of reduced (Δ) in 2-h PPBG in SC was significantly different from control (Δ-18.75 ± 10.9 vs. Δ2.75 ± 12.4, p = 0.04) and AD (Δ-18.75 ± 10.9 vs. Δ6.37 ± 11.8, p = 0.02).

Conclusions. Static cycling exercise improved 2-hour postprandial blood glucose and systolic blood pressure significantly more than aerobic dance in T2DM.

Published: June 2022

Introduction. The aim of the present study was to investigate the effects of a 6-week low intensity plyometric training (PT) + whole-body electrostimulation (WBES) combined program, compared with traditional PT, on vertical jump performance, 20 m sprint-time and handgrip strength.

Material and methods. 10 male and 10 female Physical Education students were randomly allocated to a control (CON) or an experimental (EXP) group. Both groups performed a 6-week low intensity PT 3 days per week, and during the third day, PT was simultaneously combined with WBES in the EXP group. Countermovement jump (CMJ) height, CMJ peak power, 20 m sprint-time and handgrip strength were measured before (pre-test) and after (post-test) the training period. Repeated measures ANOVA was performed to identify differences after the training program. Effect sizes (ES) were assessed using Hedge’s g.

Results. No significant differences between groups were observed at post-test. CMJ height and CMJ peak power significantly increased in both groups, with greater ES in the EXP group (p < 0.001, g = 0.68; p < 0.001, g = 0.70, respectively). 20 m sprint-time significantly improved in both groups, with greater ES in the CON group (p < 0.001, g = −1.68). Handgrip strength also increased in both groups, but ES were minimal.

Conclusions. Both training methods demonstrated to be a good strategy to improve CMJ performance and 20 m sprint-time. The most effective training method for improving CMJ performance was PT + WBES combined program, and traditional PT obtained better results in 20 m sprint-time.

Mexico ranks 5th in worldwide resin production. Pinus oocarpa is the most widely tapped pine tree in Mexico. Michoacán (central-western Mexico) is the first nationwide state producer of resin. Despite the P. oocarpa relevance, there is no genetic improvement program in the country for resin production. We evaluated the degree of genetic control for growth, anatomical traits, resin yield, and the correlation among them at an early age (five-years-old for growth, six for resin, and anatomical traits) in a P. oocarpa half-sib progeny trial. Families were originated from selected mother trees, based on their resin yield. We found significant genetic variation among families for stem volume (h

Results suggest that the early selection (six-years-old) of superior P. oocarpa families, based on resin yield (estimated by microchipping technique), and/or based on larger diameter and area of traumatic ducts, appears to be a feasible strategy to develop seed orchards able to provide genetically improved seeds for intensive resin tree plantations. That would be an important alternative for a state as Michoacán, Mexico, where natural P. oocarpa stands are being replaced for avocado orchards for exportation.
