title: <b>HYDROCHEMICAL ASSESSMENT OF GROUNDWATER QUALITY AND ITS SUITABILITY</b><b> </b><b>FOR</b><b> </b><b>IRRIGATION</b><b> </b><b>AND DOMESTIC PURPOSES</b><b> </b><b>IN</b><b> </b><b>BREEDE</b><b> </b><b>WATER MANAGEMENT AREA, WESTERN CAPE</b>

description: <strong>Ethics Clerance number is 220164711/10/2021 </strong>
<br>
The study was conducted in the Breede Water Management Area in the Western Cape province in South Africa. The aim was to assess the status of groundwater quality, the suitability of the water for domestic and irrigation purposes and factors contributing to the groundwater chemistry. Twelve (12) monitoring boreholes were selected for sample collection. The samples were analysed for major ions such as potassium (K+), magnesium (Mg2+), sodium (Na+), calcium (Ca2+), chloride (Cl-), sulfate (SO42-), bicarbonate (HCO3-), nitrate (NO3-), fluoride (F-) and physical variables like pH, electrical conductivity (EC), total dissolved solids (TDS) and temperature.

title: Entomopathogenic Fungal Species Occurrence in the Cape Peninsula Region - Winter and Summer

description: Entomopathogenic fungal isolates are increasingly being used to develop eco-friendly biopesticides. This dataset is based on a study investigating the ecological relationships between entomopathogenic fungal occurrence in the Cape Peninsula region and season and land use. Soil samples were collected in winter and summer from randomly selected sampling sites within randomly selected nature reserves (undisturbed sites) and agricultural farms (disturbed sites) in the Cape Peninsula region. Soil samples from the same sites were collected in different seasons (winter and summer). The isolates were identified morphologically and molecularly. The results will help enhance the conservation biological control approach and understand the ecology of these important microbes in the region.

title: Dataset: <strong>Crop yields, secondary metabolites and anti-fungal activities of extracts of </strong><em><strong>Helichrysum cymosum</strong></em><strong> and </strong><em><strong>Helichrysum odoratissimum</strong></em><strong> cultivated in aquaponics </strong>

description:  The growing demand for herbal remedies has resulted in the significant over-harvesting of wild plants, exacerbating the problem of species extinction. This study evaluates two cultivation approaches that could be explored to cultivate medicinal plants.  This study compared the antifungal activities, secondary metabolite contents, and crop yields of <em>Helichrysum cymosum </em>and <em>Helichrysum odoratissimum</em> extracts cultivated in aquaponic and hydroponic systems to assess the prospects of using both systems in the sustainable cultivation of medicinal plants.  The different cultivation methods (soil, aquaponics and hydroponics) were compared. Data on plant growth, antifungal activity, antioxidant activity, secondary metabolites and volatile compounds were collected and are presented.

Two methods for calibration of low frequency AC voltage using quantum voltage standard were compared: 1, classic differential method where digitizer measures difference between device under test and a step sine like signal generated by programmable josephson voltage standard. 2, quantum power method, where digitiser is first calibrated using programmable josephson voltage standard, and after a switch of multiplexer digitiser directly measures voltage of a device under test.

title: Dataset of PMU calibrator calibration.

description: Calibration data for calibration of Phasor Measurement Unit calibrator. Data includes GNU Octave script to process and display results.

The calibration method relies on the properties of a two channel digitizer with a time base common toboth ADCs. Because of the common time base, time errors of samples acquired by first channel are almost the same as the time errors of the samples acquired by second channel. The first channel is used to calibrate the time base and the second channel is used to sample the synchrophasor waveform. 

Data are part of paper published in 25th IMEKO TC4 International Symposium, 23rd International Workshop on ADC and DAC Modelling and Testing, IMEKO TC-4 2020, Brescia, Italy / September 12-14, 2022.

title: Clinical data for <b>Disordered eating behaviour is not associated with sexual risk taking behaviour amongst emerging adults attending a tertiary education institution in Coastal Kenya: a latent class analysis approach</b>

description: <b>Background</b>Sexual risk-taking behavior is a well-documented pathway to HIV acquisition in emerging adults and remains common amongst African emerging adults. We aimed to describe the relationship between disordered eating behavior and sexual risk-taking behavior amongst emerging adults attending a tertiary educational institution at the Kenyan Coast.<b>Methods</b>We applied a<b> </b>cross-sectional design nested in a young adults’ cohort study. Eligibility included sexually active emerging adults aged 18-24 years. Three disordered eating behaviors (emotional, restrained and external eating) were assessed using the Dutch Eating Behavior Questionnaire and analyzed using exploratory factor analysis. Seven sexual risk-taking behavior indicators were assessed: non-condom use, casual sex, multiple sex partners, transactional sex, group sex, age-disparate relationship and anal sex, and grouped into low vs. high sexual risk-taking behavior using latent class analysis. Logistic regression was used to assess the association between disordered eating behavior and sexual risk-taking behavior.<b>Results</b>Of 273 eligible participants (female, n =110 [40.3%]), the mean [SD] of emotional, restrained and external eating was 1.9 [0.6], 2.0 [0.6] and 3.0 [0.5] respectively. Overall, 57 (20.9%) were grouped into the latent high sexual risk-taking behavior class. Emotional (Adjusted odds ratio {AOR [95% confidence interval, CI]: 1.0 [0.9 – 1.0], p = 0.398), restrained (AOR, 1.0 [CI: 0.9 – 1.1], p = 0.301) and External (AOR, 1.0 [CI: 0.8 – 1.2], p = 0.523) eating were not independently associated with latent high sexual risk-taking behavior.<b>Conclusion</b>There was no significant association between disordered eating behavior and sexual risk-taking behavior. More studies in different African settings are needed to assess this association in order to lay a strong evidence base for public health interventions on sexual risk-taking behavior and to prevent disordered eating behavior in this and similar settings.

title: <b>Investigation of MicroRNAs that can differentiate between pre-diabetes and diabetes</b>

description: <strong>NHREC: REC - 230 408 – 014 and N14/01/003</strong>
<strong>Background: </strong>An ever-increasing incidence of Type 2 Diabetes Mellitus (T2DM) in the global population, has caused a public health concern. MicroRNA are small non-coding RNAs which control gene expression and are involved in several pathophysiological processes, therefore allowing them (miRNA) to play a role in disease detection. The scarcity of studies which investigates the role of miRNA in T2DM, especially in a South African population, has encouraged studies such as the preliminary study conducted by Matsha et al. (2018), profiling miRNA in 1989 randomly selected participants where they found that the expression of hsa-miR-486-5p and hsa-miR-novel-chr1_40444 were 2 of the most dysregulated miRNA in individuals with screen detected Type 2 diabetes mellitus (DM), in comparison to those individuals who were either on treatment or were normoglycaemic. This current study further investigates and validates the expression of hsa-miR-486-5p and hsa-miR-novel-chr1_40444 in 1459 participants of the sample cohort who have participated in the miRNA profiling study.
<strong>Methods: </strong>The Quantum Studio 7 (Life Technologies, USA) was used to perform quantitative reverse-transcription PCR (RT-qPCR) on 1459 whole blood samples provided by participants who partook in the Vascular and Metabolic Health study. All the participants underwent anthropometric measurements, and biochemical parameters were measured at an accredited pathology laboratory. Participant glycaemic status was determined using the oral glucose tolerance test (OGTT).
<strong>Results: </strong>Hsa-miR-486-5p and hsa-miR-novel-chr1_40444 were significantly overexpressed in diabetics compared to both controls, and prediabetics (all p≤ 0.001). Moreover, multivariate regression analysis revealed independent associations between the expression of both miRNAs and the risk of diabetes, with significant retained in unadjusted and adjusted models (all p≤0.001).
<strong>Conclusion: </strong>This study has demonstrated the potential capabilities of hsa-miR-486-5p and hsa-miR-novel-chr1_40444 in distinguishing between Type 2 diabetes (both newly-diagnosed and known diabetes) from normoglycaemia and early-stage hyperglycaemia (pre-diabetes). However, further investigation is required.
