Validity and Reliability of Strategy Metrics to Assess Countermovement Jump Performance Using the Newly Developed My Jump Lab Smartphone Application
Authors: Bishop Chris , Jarvis Paul , Turner Anthony , Balsalobre-Fernandez Carlos
Published: September 2022

The aim of the present study was to analyse the validity and reliability of the newly developed My Jump Lab smartphone app, which includes the option to calculate time to take-off and the reactive strength index modified (RSI_Mod – calculated as jump height divided by time to take-off), in addition to jump height. Twenty-seven postgraduate sport science students attended a single test session and performed three maximal effort countermovement jumps (CMJ) on twin force plates, whilst concurrently being filmed using the app. Results showed no significant differences in jump height between measurement methods (g = 0.00) or RSI_Mod (g = -0.49), although a significant difference was evident for time to take-off (g = 0.68). When a correction factor was applied to time to take-off data, no meaningful differences were evident (g = 0.00), which also had a knock-on effect for RSI_Mod (g = 0.10). Bland-Altman analysis showed near perfect levels of agreement for jump height with a bias estimate of 0.001 m, whilst time to take-off reported a bias estimate of 0.075 s initially and, 0.000 s once the correction factor was applied. For RSI_Mod, bias estimate was initially -0.048, and 0.006 once calculated with the corrected time to take-off data. Pearson’s r correlations were: 0.98 for jump height, 0.81 for time to take-off, and 0.85 for RSI_Mod. Based on the findings from the present study, and with the inclusion of the newly embedded correction factor, My Jump Lab can now be used as both a valid and reliable means of measuring time to take-off and RSI_Mod in the CMJ.

Regional/Rural Workforce Transitions for Post-COVID-19 Resilience
Authors: Babacan Hurriyet
Published: September 2022

The pandemic has intensified the way we think about global challenges. Humanity now faces a ‘triple conjuncture’ of global crises: climate change and ecological breakdown; a systemic crisis of global capitalism; and the current global Coronavirus pandemic (Gills, 2020). The impacts of the pandemic are not experienced uniformly. They are amplified by social and economic vulnerabilities, labour market structures, precarious employment in some industries, and pre-existing inequities (Babacan et al., 2021, Spash, 2020). Regional/rural economies in Australia have undergone significant structural change and adjustment in the last three decades. Economies also have distinct characteristics and diverse strengths and needs and have been experiencing economic change at different magnitudes, speeds and intensities. Climate change is one of the greatest ecological events of our time. Scientists continue to give dire warnings about climate change amidst major global debate about the nature and extent of climate change.  How well a place or region can adapt is complex. A study into the adaptive capacity of regions showed a strong correlation between low levels of adaptive capacity and remoteness (Productivity Commission 2017). Factors that contribute to adaptive capacity are linked to education, skills, levels of income, employment, health, access to infrastructure and services, and natural resources. Alarmingly, most of rural and regional Queensland falls below average adaptive capacity. Addressing future policy and regulatory challenges for the future of work requires a more in-depth understanding of the fragmentation impacts of work, changing employer arrangements and workplaces, and workers’ conditions across different regional/rural locales.
Implementation of Circular Economy in Peatlands to Support Sustainable Food Security in Post Covid-19 Era
Authors: Pertiwiningrum Ambar , Wuri Margaretha Arnita , Sugiyanto Catur
Published: September 2022

The peatlands in Indonesia have changed quite a lot in recent years due to over-exploitation and climate change. The land-use change on peatlands resulted in soil infertility. The impacts of the degradation of peatlands are almost certain to worsen with the COVID-19 pandemic because the peatlands have an important role in providing food resources. Therefore, the peatlands restoration must be carried out considering the importance of the peatlands as food resources and carbon capture. One of the alternative solutions is to recycle the waste from agroforestry into organic fertiliser. This study aimed to investigate the application of organic fertiliser to restore soil fertility in the peatlands. The study also offered the circular economy scheme that can be applied in the peatlands to restore sustainability. The results showed that the degraded peatland that has been restored by adding organic fertiliser from local sources has a higher soil pH level than the one without adding organic fertiliser. The increase in pH level can decrease soil hydrophobicity and increase microorganism activities, encouraging biodiversity in the peatlands. In this study, the circular economy scheme by the integration between agroforestry and livestock was assessed economically and environmentally. Recycling cows’ manure and leaf litter from peatlands into energy and recycling biogas sludge into biochar for biogas purification and soil enrichment benefit economically and contribute to mitigating greenhouse gas emissions.

Published: September 2022

Jogo Tonggo - a social activity from, by, and for the community based on local wisdom, is initiated by the Central Java Provincial Government to anticipate the negative implications of COVID-19 on the health, social and economic sectors. However, in practice, the role of formal key figures (Babinsa, Babinkamtibmas, and Village Midwives) and non-formal (RT/RW) in the context of social capital is a determining factor for the success of the implementation of Jogo Tonggo. The study's objective is to analyse the determinants that influence the success of the implementation of Jogo Tonggo in tackling the impact of the spread of COVID-19 on the health, social, and economic sectors of the community. Primary data were obtained through direct interviews with respondents consisting of key formal figures (Babinsa, Babinkamtibmas, Village Midwives), non-formal (RT/RW), and people exposed to COVID-19. Secondary data is obtained from BPS, related ministries and institutions, and the results of previous studies. Data is analysed descriptively and qualitatively. The results showed that Jogo Tonggo's activities in Central Java helped minimise the spread of COVID-19 and helped recover residents affected by COVID-19 through food assistance provided during the quarantine. The assistance provided to the affected communities has also succeeded in preventing social problems and ensuring security. The strength of social capital supported by community participation and the integration between formal and non-formal figures determine the success of the implementation of Jogo Tonggo.

TG4 and SR2 were isolates of indigenous bacteria from cassava roots from Banyumas Regency, Central Java. Both are local isolates from marginal lands that can be developed as biofertilizers. This study aimed to determine the potential characteristics of bacterial isolates TG4 and SR2 in supporting the growth of superior upland rice and determining species identity based on the molecular analysis of 16S rRNA. Bacterial isolates TG4 and SR2 were determined for their potency of Plant Growth Promoting Rhizobacteria (PGPR) by fixing N2, dissolving phosphate, and producing Indole Acetic acid (IAA). Bioassays were carried out on TG4 and SR2 isolates by application of bacterial isolates (B0 = control, B1 = TG4, B2 = isolates SR2, B3 = isolates TG4 and SR2) on superior upland rice (V1 = INPAGO UNSOED 1, V2 = UNSOED PARIMAS, V3 = INPAGO 8) in sterile ultisol soil. The F test was used for bioassay data analysis, and if there was a significant difference, it was further tested with Duncan's Multiple Range Test (DMRT) with an error rate of 5%. The identity of bacterial species TG4 and SR2 was obtained by analyzing 16S rRNA sequences and genetic relationships through phylogenetic trees. The results showed that the isolates of TG4 were phosphate solubilizing bacteria and producers of IAA, while the isolates of SR2 were nitrogen fixing, phosphate solubilizing, and IAA producers. The application of bacterial isolates TG4 and SR2 significantly affected root length wet and dry weight of upland rice plants, with the highest value obtained from using a consortium of TG4 and SR2 bacteria. Bacterial isolates TG4 were identified as Bacillus albus, while SR2 as B. Paramycoides. Bacterial isolates TG4 and SR2 can be used as biofertilizers to support superior upland rice growth.
Diabetic Foot Ulcer: Treatment Challenges
Authors: Bolton Laura
Published: September 2022

Wound care professionals face complex challenges in their attempts to achieve healing in patients with a diabetic foot ulcer (DFU).1 Peripheral neuropathy limits sensation, which necessitates consistent offloading of the DFU site. Peripheral arterial, venous, or lymphatic circulation disorders must be diagnosed and addressed. Early diagnosis and management of soft tissue or bone infection is required. Chronic kidney disease, glycemic control, and nutritional needs must be addressed along with counterproductive behavior patterns.2 The use of topical hydrocolloid-based hydrogel dressings3 or honey4 on DFUs facilitates moist wound healing and debridement. Randomized controlled trials (RCTs) indicate that carefully controlling all of these factors helps optimize outcomes for individuals with a DFU. Promising phase 2 clinical studies with stringent inclusion criteria and rigorously applied diagnostic and management procedures are rarely replicated in larger phase 3 RCTs with broader inclusion criteria and less rigorously applied DFU management procedures. Narrow RCT inclusion criteria can limit study applicability for the general DFU population. This installment of Evidence Corner reviews 2 RCTs that use different approaches to address these issues. The first RCT reports interim results of a new autologous skin construct applied to Wagner grade 1 DFUs.5 The second compares the effects of standard wound dressings (SWDs) vs negative pressure wound therapy (NPWT) applied to Wagner grade 2, 3, or 4 DFU according to standard protocols during real-world clinical practice in German patients.6
The Correlation between Iron Deficiency and Recurrent Aphthous Stomatitis

Aphthous lesions of the oral mucosa are a very common symptom and can be seen in both family medicine practice, dental medicine practice, and dermatology or otorhinolaryngology clinics. Some patients develop a chronic recurrent condition, which is clinically known as recurrent aphthous stomatitis (RAS). These ulcers are round, clearly defined, and can be visible on the movable part of the oral mucosa, with variations in size. A prodromal symptom like the burning or stinging sensation can precede the appearance of lesions. The main reason why patients seek medical help is oropharyngeal pain with lack of appetite.The exact etiopathogenesis of RAS remains unknown. Immune disorders, nutritional deficiencies, allergies, mechanical injuries, and even psychological disorders are being studied as potential causes of this condition. Some authors claim that iron deficiency may be a possible causative factor of RAS due to its role in DNA synthesis, mitochondrial function, and enzymatic activity. In iron deficiency, epithelial cells turn over more rapidly and produce an immature or atrophic mucosa. Such mucosa is vulnerable and can be a fertile soil for chronic inflammation and development of aphthae.Finally, our goals were to describe the clinical aspects and etiology of RAS, as well as to determine whether RAS may be related to iron deficiency, in order to identify potential patients with iron deficiency in everyday work.

COVID-19 is currently a major global health concern. Among many unanswered questions related to COVID-19, some of the most debated ones are those concerning arterial hypertension. Arterial hypertension is a major risk factor for mortality worldwide and its importance has been emphasised even further in light of COVID-19. The most common antihypertensive drugs are ACE inhibitors and angiotensin II type-I receptor blockers. SARS-CoV-2 utilises the angiotensin-converting enzyme-2 (ACE2) for cell entry and therefore has a direct effect on the renin–angiotensin system (RAS). In terms of arterial hypertension and COVID-19, there are three main issues which have been the focus of extensive debates. First, is arterial hypertension a predisposing factor for COVID-19 infection? Second, does arterial hypertension affect the severity of COVID-19 infection and increase the risk of all-cause and cardiovascular mortality? And finally, how important is the interaction of COVID-19 infection and the renin–angiotensin system for clinical outcomes? Is RAS blockade beneficial or harmful? The aim of this brief review was to provide substantiated answers to these questions.
Free Radical-based Sequencing for Native Top-Down Mass Spectrometry

ABSTRACT: Native top-down proteomics allows for both proteoform identification and high-order structure characteri-zation for cellular protein complexes. Unfortunately, tandem MS-based fragmentation efficiencies for such targets are low due to an increase in analyte ion mass and the low ion charge states that characterize native MS data. Multiple fragmenta-tion methods can be integrated in order to increase protein complex sequence coverage, but this typically requires use of specialized hardware and software. Free-radical initiated peptide sequencing (FRIPS) enables access to charge-remote and electron-based fragmentation channels within the context of conventional CID experiments. Here, we optimize FRIPS la-belling for native top-down sequencing experiments. Our labelling approach is able to access intact complexes with TEMPO-based FRIPS reagents without significant protein denaturation or assembly disruption. By combining CID and FRIPS datasets, we observed sequence coverage improvements as large as 50% for protein complexes ranging from 36 kDa to 106 kDa. Fragment ion production in these experiments was increased by as much as 102%. In general, our results indicate that TEMPO-based FRIPS reagents have the potential to dramatically increase sequence coverage obtained in na-tive top-down experiments.
