Published: April 2021

Objectives: To investigate the ameliorative effect of garlic extract on Aluminum Phosphide induced toxicity on the liver and kidney of adult Wistar rats.
Materials: Thirty six (36) male adult Wistar rats weighing 180±20 – 250±30 g were purchased from Dantom Farms, Swali, Bayelsa State and moved to the animal house of the department of Medical Laboratory Science, Niger Delta University. The animals were assigned into six (6) major groups with six (6) animals in each group after the period of acclimatization: Animals in Group A (Control): received pelleted growers mash (feed) and water. Group B (Positive Control received 0.014 mg of Aluminum Phosphide only. Group C: received 0.014 mg of Aluminum Phosphide and 250 g of garlic extract. Group D: received 0.014 mg of Aluminum Phosphide and 500 mg of garlic extract. Group E: received 500 mg of garlic extract, Group F: received 0.6 ml of oil at the end of the treatment, the liver and the kidney of each sacrificed rat were processed for paraffin sectioning and stained with Harris hematoxylin and eosin.
Result: Photomicrograph of the liver of animals in Groups B, C and D show central venous congestion, degeneration, hemorrhage, sinusoidal dilation, bile stasis, centrilobular necrosis, Kupffer cell hyperplasia, inflammatory cells and fat infiltration which are features of hepatic injury also photomicrograph of the kidney of animals in Groups B, C and D shows membranous defect, contracted glomeruli with marked presence of mesangial cells, areas of tubular necrosis with mesangial cells proliferation. while the other groups (Group A, E, F) did not show any histological change in comparison with control.
Conclusion: The present study proves that the oral ingestion of Aluminum Phosphide induces hepatotoxicity and inflammation of the liver and kidney. It also shows that the use of garlic at various concentrations (250 mg/l and 500 mg/l) aggravates the tissue damage even more, and also garlic extract does not have ameliorative effect on aluminum phosphide toxicity on the liver and kidney of albino wistar rats.
Healthy Cities South Auckland: A focus on youth leadership and sustainability in the post-COVID world
Authors: Conn Cath , Field Robert , Hinepo Williams Margaret , Cammock Radilaite , Nnabugwu Adetoun 
Published: April 2021

Introduction: This paper draws on a presentation given at the American Public Health Association (APHA) annual meeting in Philadelphia in 2019 (Drs. Conn and Field). It is based on an innovative public health initiative in the Aotearoa New Zealand context, which incorporates key themes relating to sustainable and healthy cities in the post-COVID world.
Method: Healthy cities South Auckland began in 2019, and involves Auckland University of Technology (AUT) faculty and students, many of whom are from indigenous Māori and Pacific Island communities, working collaboratively. The initiative aims to improve the health and wellbeing of the urban population using a series of codesigned projects that prioritise youth leadership and principles of sustainability. Current projects include an investigation of healthy food youth enterprise and the role of urban sustainable food environments; and student, faculty, and industry codesign of future-oriented public health higher education.
Discussion: Whilst this public health initiative is grounded in known principles of community action and determinants of health, it is innovative in the close and contextualised attention to Māori and Pacific youth leadership and to a more overt sustainability agenda. Emphasising the shift from healthy cities focusing on people, to one that focuses on the inextricable link between people and the natural environment, the initiative is underpinned by indigenous guardianship concepts, such as Māori Kaitiakitanga (guardianship of the natural order) and Pacific Va (healthy spaces). Traditionally associated with rural and marine spaces, a valuable new development is the application of indigenous principles by youth in an urban setting and for a public health agenda. These notions resonate with global shifts such as the ‘school strikes for climate change’ movement and seem particularly apt in a post-COVID world which must mobilise new ways of bringing about transformative change. These include addressing disease outbreaksand chronic disease and health inequities, while also taking into consideration the contexts of community, culture and natural environments.
Conclusion: In the Aotearoa New Zealand context, strengths-based approaches are a vital way forward, positioning Māori and Pacific young people as champions. Notions of healthy cities as sustainable cities; based on indigenous guardianship applied to 21st century urban spaces; youth activism and urban health in the digital age; and partnership between academia, youth, and industry are significant areas for further study, providing useful lessons for cities’ agendas, both locally and internationally.

This research aims to determine the effect of plasticizer types and concentrations on the characteristics of glucomannan bioplastics, and to determine the types and concentrations of plasticizers that can produce glucomannan bioplastics with the best characteristics. This experimental design used a completely randomized design method. Factor I is a type of plasticizer consisting of glycerol, sorbitol, propanol-2, and polyethylene glycol. The second factor is the concentration of plasticizers which consists of 4 levels, namely 0.5%: 1.5%: 2.5%: 3.5%. The experiment resulted in 16 treatment combinations and grouped into 2 groups to obtain 32 experimental units. The data were analyzed for their diversity and continued with the Duncan multiple comparison test. The results showed that the type and concentration of plasticizers had a very significant effect on tensile strength, elongation at break, modulus young, and swelling. The interaction has a very significant effect on tensile strength and expansion and has a significant effect on the elasticity of glucomannan bioplastics. Meanwhile, the type and concentration of plasticizers had no significant effect on the length of biodegradation. The best glucomannan bioplastic was obtained in the treatment of glycerol plasticizers with a concentration of 1.5 % with a tensile strength value of 6.17 MPa, elongation at break of 21.50 %, elasticity 28.72 MPa development 25.84 %, and degradation time of 8 days. Bioplastics produced in this study have meet the SNI 7188.7:2016 standards in the elongation test at break and standards ASTM 5336 in the degradation time variables. The resulting bioplastic has not met SNI on the tensile strength, modulus young, and swelling variables.

Published: April 2021

Citrate-gel auto combustion technique was used to synthesize nickel-copper mixed ferrite nanoparticles NixCu1-xFe2O4 (x= 0.0, 0.4, 1.0) with different calcinating temperatures (200, 450, 650 and 850 °C). Structural, morphological, magnetic, and electrical properties were studied using X-ray diffraction (XRD), transmission electron microscopy (TEM), field emission scanning electron microscopy (FE-SEM), Fourier transform infrared spectroscopy (FTIR), vibrating sample magnetometer (VSM), and LCR meter in order to determine significant influences of Cu2+ cations content in nickel ferrite. The XRD patterns showed that all compositions had cubic spinels, except CuFe2O4 samples. The system structure in Cu-ferrite was deformed at 650 °C from a cubic to a tetragonal system with a secondary phase CuO. Lattice constant was decreased with increasing Cu2+ cations substitution in Ni-ferrites, while crystalline volume was increased. With the help of Debye-Scherrer`s equation using XRD data, we found that the crystallite size at 850 °C is lying in the range from 38.70  to 48.00 nm. The FTIR spectrum of samples under investigation showed two significant absorption bands, which refer to the formation of a single-phase cubic spinel. The magnetization test revealed a soft ferromagnetic behavior for all the compositions sintered at 850 °C. The saturation magnetization (Ms) was decreased with the substitution by Cu2+ cations, while remnant magnetization (Mr) and coercivity (Hc) were increased in Cu-ferrite. The highest Ms value was 42.25 emu.g-1 for Ni-ferrite, while the highest Hc value was 517.16 Oe for Cu-ferrite. The electrical measurement of samples showed an increase in the real dielectric constant and AC conductivity at a frequency range of 20Hz-3MHz with the addition of copper cations.

Published: April 2021

Compressive Strength (CS) is an important mechanical feature of concrete taken as an essential factor in construction. The current study has investigated the effect of fly ash and silica fume replacement content on the strength of concrete through Artificial Neural Networks (ANNs) and Extreme Learning Machine (ELM). In this study, different ratios of fly ash with (out) extra quantity of silica fume have been tested. Water cement (w/c) ratio varies during the test. Eight input parameters including Total Cementitious Material (TCM), Silica Fume (SF) replacement ratio, coarse aggregate (ca), fly ash (FA) replacement ratio, Sewage Sludge Ash (SSA) as a combination of cement and fine aggregate replacement, water-cement ratio, High Ratio Water Reducing Agent (HRWRA) and Age of Samples (AS) and one output parameter as the CS of concrete have been investigated through ANN and ELM. Up to now, numerous experimental studies have been used to analyze the compressive strength of concrete while retrofitted with fly ash or silica fume, however, the novelty of this study is in its use of AI models (ELM, ANN). The models have been developed and their outcomes were compared through six statistical indicators (MAE, RMSE, RRMSE, WI, RMAE and R2). Subsequently, both methods were shown as reliable tools for assessing the influence of cementitious material on compressive strength of concrete, however, ANN remarkably was better than ELM. As a result, FA showed less contribution to the strength of concrete at short times, but much at later ages. As a result, the enhanced influence of low amount of SF on CS was not significant. Adding fly ash has reduced the compressive strength in short term, but increased the compressive strength in long term. Adding silica fume raises the strength in short term, but decreases the strength in long term.

Textile-and-garment industry is one of the largest economic sectors in Vietnam, with 4000 enterprises and a turnover of 20 billion USD/year. Therefore, designing and manufacturing are essential tasks for roll fabric cutting machines to serve the textile and garment industry. First of all, theoretical calculations are formulated for an automatic roll cutting machine. Then, simulations are conducted by a combination of MITcalc and Catia software. A prototype of a fabric cutting machine is manufactured and experiments are implemented. The experimental results show that the machine stably works and overcomes the disadvantages of the popular cutting machines with the core-free roll on the market. The results also found that the size tolerance is achieved about ± 0.5 mm, and this ensures good working quality. The designed machine has a significant contribution to the textile and garment area in decreasing the cost of the cutting process.

On a psychological aspect, this pandemic has caused anxiety due to low mindfulness. To increase the potential of mindfulness, one of the ways taken is by counselor psychological intervention. The authors used an Islamic counseling approach to reduce anxiety and increase mindfulness. Therefore, the research was conducted using a quasi-experimental design with non-equivalent control group design. Participants in this study were 14 students consisting of 7 students for each experimental and control group. Participants were invited after filling self-report the anxiety scale facing COVID-19 and indicated that they were in the high category. The data analyzed with the Wilcoxon sign rank test to determine the impact of before and after the intervention was given, then used the Mann Whitney to find out the mean differences between the experimental and control group, and the Rank Spearman to determine the correlation between mindfulness and anxiety. The results showed that Islamic counseling intervention is effective to increase mindfulness which impacted on reducing anxiety in facing the COVID-19 pandemic. Besides, the results of correlation analysis using the Rank Spearman show that there is a correlation between mindfulness and anxiety.

The Alkaline Diet and the Warburg Effect
Authors: Bahrami Hassan , Greiner Ted 
Published: April 2021

The changing diets accompanying our modern life style have increased the content of foods that form acidic metabolic waste residues in the body. Wastes from these metabolic processes are released into the interstitial fluids and the blood, slightly changing their pH temporarily. This link may in turn have an impact on the incidence of non-communicable diseases (NCDs).
According to Warburg effect theory, an acidic cellular and circulatory environment may cause various specific health problems such as hypoxia and cancer, whereas an oxygen-rich optimum-alkaline environment could retain healthy cells. However, the mechanisms by which the diet may be influential on blood pH-related parameters and on health have remained largely unknown.
This paper begins with a detailed presentation of the concepts, issues and the existing evidence regarding alkaline and acid forming diets, and summarizes the three main mechanisms by which the diet influences the acid-base balance in the body. It then presents the findings of a small exploratory study in which one author (HB) followed diets traditionally thought to produce alkaline or acidic residues. After each diet period of one month (with a two-month wash out period), pH, oxygen saturation, and carbon dioxide partial pressure were measured for arterial and for venous blood.
The resulting data indicated that the diets followed changed blood pH-related parameters in the expected directions according to the acid-base theory of health. Increased intake of acid-forming foods resulted in a slightly lower pH level, but a significant reduction of oxygen saturation in the blood, whereas increased consumption of alkaline forming foods maintained the high oxygen saturation in the blood that, according to Warburg effect theory, may, if maintained, reduce the incidence of NCDs. Further cross-over research of this kind is needed, utilizing large samples and testing various dietary modifications.

Published: April 2021

Background Hop tests are commonly employed to evaluate functional limb symmetry after anterior cruciate ligament reconstruction (ACLR). Purpose To investigate the ability of eight hop tests to identify functional limb asymmetry in patients after ACLR. Study Design Prospective cohort. Methods Fifty patients were assessed 9-12 months following ACLR. Functional performance on both the operated and non-operated limb was assessed via eight hop tests, assessed in a randomised order. These included the: single (SHD), triple (THD) and triple crossover (TCHD) hop for distance, 6m timed hop (6MTH), single medial (MHD) and single lateral (LHD) hop for distance, single countermovement jump (SLCMJ) and timed speedy hop (TSHT). Differences in Limb Symmetry Indices (LSIs) across hop tests were compared, while Pearson’s correlations were undertaken to investigate the significance and strength of the association between hop test LSIs. Results Significant differences were observed across hop LSIs (p<0.0001). Mean LSIs for the SHD (95.0%), 6MTH (95.0%), THD (96.1%) and TCHD (95.3%) were ≥90% and significantly greater (p<0.05) than the MHD (87.3%), LHD (87.5%), SLCMJ (83.4%) and TSHT (86.5%), which were all <90%. The LSI for the SLCMJ was significantly lower (p<0.05) than all other hop tests. While significant correlations existed across the majority of hop LSIs, the strongest correlations existed between the SHD, THD and TCHD (r=0.70-0.80), and lowest correlations between the TSHT and the other hop tests (r=0.26-0.49). Conclusions The LHD, MHD and TSHT, as well as the SLCMJ in particular, were best able to demonstrate functional limb asymmetry in patients following ACLR. These hop measures should be incorporated into hop test batteries, if the purpose is to detect the presence of lingering functional deficits. Level of Evidence Level 3.
