The need to find alternative water disinfectants without negative consequential health effects is imperative in view of the link that had been established between human consumption of chlorinated water and diseases such as cancer. Therefore, this study was set out to evaluate and compare the water disinfection potential of aloe vera and sodium hypochlorite (NaOCl) in order to determine the suitability of using aloe vera as sodium hypochlorite substitute. The coliform count of the faecal thermo-tolerant coliform (non-Ecoli) isolated from well water sample was 49 cfu/100ml. Disinfectant efficacies of the NaOCl and Aloe Vera, stored under various conditions, were evaluated and compared using disc diffusion method to determine disinfection susceptibility of the isolated coliform. The two disinfectants showed increase in level of zone of inhibition of the isolated coliforms with increase in disinfectants storage concentration and sun exposure period. As a disinfectant, aloe vera seemed to be more stable when compared with NaOCl at the storage temperatures of 0, 25 and 35oC. The p-values for using aloe vera and NaOCl as disinfectants under various conditions of concentration, temperature and sun exposure period ranged between 0.247 and 1.000 indicating non-significant difference when aloe vera was used as sodium hypochlorite substitute.

The objective of this study was to investigate the changes in physicochemical, microbiological, and sensory properties of sun-dried Mystus vittatus during storage at ambient temperature. The fish was dried under sun exposure on bamboo mats for 5–6 days until the moisture content reduced to approximately 10–15%. The dried fish was then packed into airtight polyethylene bags and stored at ambient temperature (24 to 29 °C) for 90 days. The physical and sensory properties revealed that the dried fish was acceptable for human consumption for up to 60 days. The pH value slightly decreased from 6.42 to 5.95 during the storage period. The moisture content increased significantly (p < 0.05), while no significant difference was observed for the protein, lipid, and ash contents (on a dry matter basis) with the increase in the storage time. The peroxide value, acid value, and conjugated dienes of the lipids increased significantly during the storage period. The microbial load also increased with the increase in the storage period. The results of this study suggest that the product was slightly oxidized during the storage period and could be stored for up to two months.

In order to harvest selenium-enriched fruiting body and spores of Ganoderma lingzhi and spent medium, G. lingzhi was cultivated in kudzu vine as substrate and the bio-transformation of selenite was evaluated. The growth medium consisted of Kudzu vine supplemented with 20% wheat bran or sawdust or none. The growth medium was supplemented with 0, 10, 20, 30, and 50 mg/kg of sodium selenite. We found a significant difference in spawn run speed, fruiting body and spore yields when Kudzu vine was supplemented with wheat bran or sawdust. However, when whole-kudzu vine was used alone as substrate, it resulted in a significantly lower spawn run speed, fruiting body, and spore yields compared with kudzu vine + sawdust substrate and kudzu vine + wheat bran substrate. The selenium content in fruiting body and spores increased with increasing sodium selenite supplementation and approximately equaled half of the selenium in the substrate. No selenite was detected in both the fruiting body and spores. However, in the spent medium when sodium selenite was supplemented at 10, 20, 30, 50 mg/kg, the residual selenite concentration decreased to 0.45, 0.72, 1.29, and 1.95 mg/kg, respectively, suggesting a higher selenite transformation (92.27–93.57%). In conclusion, if Ganoderma fruiting body and spores were to be harvested for human consumption, approximately 50 mg/kg selenite should be added to the growth substrate. On the other hand, if the spent medium was to be used as an organic selenium source, the optimal sodium selenite supplementation level would be 10 mg/kg.

Background:Diabetic foot ulcer (DFU) is one of the most common complications of diabetic patients. Mostly, non-healing DFU leads to infection, gangrene, amputation and even death. High costs and poor healing of the wounds need a new treatment such as alternative medicine. So, the aim of this study was to evaluate the efficacy of Aloe vera/ Plantago major gel (Plantavera gel) in healing of DFUMethods:Forty patients with DFU enrolled in a double-blind randomized clinical trial. The patients who were randomly assigned into the intervention group (n = 20), received topical Plantavera gel in addition to the routine cares, whereas the patients in the control group (n = 20), received topical Placebo gel in addition to the routine cares. Intervention was done twice a day for 4 weeks in the both groups. Photography and an evaluation of DFU healing were conducted by a checklist and then were scored at baseline and at the end of each week. The collected data was analyzed by SPSS software.Results:At the end of the study, there was a significant difference between the two groups in terms of total ulcer score (P<0.001) and Plantavera gel significantly reduced the ulcer surface comparing with the control group (P=0.039). However, there was not a significant difference between the two groups (P=0.263) in terms of the ulcer depth. During this study, no side effect was observed for Plantavera gel in the intervention group.Conclusion:Topical Plantavera gel seems to be an effective, cheap and safe treatment. Of course, further studies are required to confirm the properties of the wound healing of this gel.

Bacterial infections are on a rise with causal-resistant strains increasing the economic burden to both patients and healthcare providers. Salons are recently reported as one of the sources for transmission of such resistant bacterial strains. The current study aimed at the identification of the prevalent bacteria and characterization of quaternary ammonium compound (qac) genes from disinfectant-resistant S. aureus isolated from salon tools in Ishaka town, Bushenyi District of Uganda. A total of 125 swabs were collected from different salon tools (combs, brushes, scissors, clippers, and shaving machines), and prevalent bacteria were isolated using standard microbiological methods. Identification of isolated bacteria was done using standard phenotypic methods including analytical profile index (API). Susceptibility patterns of the isolated bacteria to disinfectant were determined using the agar well diffusion method. Quaternary ammonium compound (qac) genes (qacA/B and qacC) associated with disinfectant resistances were detected from disinfectant-resistant S. aureus using multiplex polymerase chain reaction (PCR) and Sanger sequencing methods. Of the 125 swab samples collected from salons, 78 (62.4%) were contaminated with different bacteria species. Among the salon tools, clippers had the highest contamination of 20 (80.0%), while shaving machines had the lowest contamination of 11 (44.0%). The most prevalent bacteria identified were Staphylococcus epidermidis (28.1%) followed by S. aureus (26.5%). Of all the disinfectants tested, the highest resistance was shown with sodium hypochlorite 1%. Out of the eight (8) disinfectant-resistant S. aureus analysed for qac genes, 2 (25%) isolates (STP6 and STP9) were found to be qacA/B positive, while 2 (25%) isolates (STP8 and STP9) were found to be qacC gene positive. This study has shown that bacterial contamination of salon tools is common, coupled with resistance to disinfectants with sodium hypochlorite resistance being more common. Furthermore, observed resistance was attributed to the presence of qac genes among S. aureus isolates. A search for qac genes for disinfectant resistance from other bacteria species is recommended.

Introduction: The daily use of orthodontic removable plates can interfere with the self-cleansing function of the mouth. Although various techniques have been proposed for cleaning removable orthodontic appliances, there is no consensus on the use of a safe method that preserves the physical properties of the appliance. This study aimed to investigate the effect of using hydrochloric acid (10%, for removal of mineral deposits) and sodium hypochlorite (5.25%, to remove organic matter and discolorations) on surface hardness and roughness of self-cure orthodontic acrylic resins. Materials & Methods: This cross-sectional laboratory study was conducted in the fall of 2017 at Isfahan University of Medical science and Isfahan University of Technology. In this study two orthodontic acrylic resins (Orthocryl® and Acropars®) were used. Eighty samples (12×10×3 mm) from each one were fabricated and divided into four groups (n = 20). Group 1: 15 minutes immersion in household cleaner liquid (Hydrochloric acid, 10%) followed by15 minutes immersion in household bleach liquid (Sodium Hypochlorite, 5.25%). In group 2, immersions were repeated just like group two times and in group 3, were done three times. Group 4 was as control and had no immersion. The surface hardness and roughness of samples were measured. Data were analyzed with Two Way ANOVA and the significance level was set at 0.05. Results: The number of immersion procedures did not significantly affect the surface hardness (p value = 0.958) and surface roughness (p value = 0.657) in the different study groups. There was no significant difference in the surface hardness between the two acrylic resin brands (p value = 0.077); however, Acropars acrylic resin samples exhibited significantly higher surface roughness compared to the Orthocryl acrylic resin samples(p value < 0.001). Conclusion: 15 minutes of immersion in 10% HCl, followed by 15 minutes of immersion in 5.25% NaOCl and repetition of the procedure three times did not significantly affect the surface hardness and roughness of self-cured acrylic resins.

Modern medicines that are developing now come from active ingredients isolated from plants that require large amounts of plants. The development of new drugs from endophytic fungi found obstacles in the amount of pure compounds produced. Therefore further research is needed by using endophytic fungi as a new antimicrobial producer. This study aims to see the ability or activity of pure compounds produced by Sporothrix sp endophytic fungi from Dahlia tuber (Dahlia variabilis). Test the activity of pure compounds produced by Sporothrix sp. Endophytic fungi on E. coli and Staphylococcus aureus determined by disc diffusion method. With doses of 10, 30 and 50μg/disk. In Escherichia coli bacteria doses 10 and 50μg/disk gave significant inhibition of pure compounds from isolation compared to the positive control of ciprofloxacin, which was marked by a statistically significant test result (p <0.05). In contrast to Staphylococcus aureus there was no significant difference in doses of both doses of 10.30 and 50μg/disk. Determination of pure compounds was carried out by HPLC and Infra Red Spectrophotometry.

Sinbiotic drinks have a very acidic taste, so it is necessary to add sucrose solution to get the best taste. This study aims to determine the effect of adding 65% (v/v) sucrose solution to changes in antibacterial activity of green grass jelly synbiotic drinks during storage in cold temperatures. The finished green grass jelly synbiotic product was given two different treatments, namely the product without the addition of sucrose solution and product with the addition of 10% (v/v) of 65% (b/v) sucrose solution. The product was stored for 28 days at a cold temperature of ± 10oC. Observations were carried out every 7 days for antibacterial activity, pH, total acid, and total lactic acid bacteria. Antibacterial activity was evaluated using the agar diffusion method against pathogenic bacteria including Staphylococcus aureus, Salmonella sp., Bacillus cereus, and Eschericia coli. The results showed that the antibacterial activity, pH, and total lactic acid bacteria of green grass jelly synbiotic drinks both without and with the addition of 65% (b/v) sucrose as much as 10% (v/v) reduced during storage at cold temperatures, while total acid increases. There was no significant difference between the antibacterial activity and the characteristics of the green grass jelly synbiotic drink given 65% sucrose solution and without the addition of 65% sucrose solution. Thus the study concluded that the addition of 65% sucrose solution to increase the preference for the product did not significantly affect the change in antibacterial activity of the green grass jelly synbiotic beverage during storage in cold temperatures.
