Published on: 15th June, 2021

OCLC Number/Unique Identifier: 9124793207

Background: The plant Artemisia annua has been used in traditional Chinese medicine for many years. Rich in bioactive molecules, the A. annua plant is used to extract the anti-malaria compound artemisinin (< 1%), which results in most of the plant being unutilized. One byproduct of artemisinin extraction is artemisia naphtha (AN), which has yet to be studied extensively. Aims: Study the activity of a novel AN oil extract against microbes, pro-inflammatory cytokines, and dermatological endpoints that are key for eczema and acne pathogenesis to determine if an effective A. annua extract for these skin conditions can be developed. Methods: Gas chromatography-mass spectrometry was performed to determine the composition of AN oil. P. acnes, S. aureus, M. furfur, and C. albicans were cultured to determine minimal inhibitory concentration. in vitro studies utilizing keratinocytes and macrophages were treated with AN oil and gene expression measured by quantitative RT-PCR. A 13-subject clinical trial was performed with 1% AN oil Gel to assess its potential benefits for sensitive and acne prone skin. Results: AN oil upregulates filaggrin gene expression and possesses antimicrobial and anti-inflammatory activity inhibiting LPS, S. aureus and "Th2 induced" pro-inflammatory mediator release (IL-6, IL-8 and TSLP). Clinical assessment of 1% AN Gel shows it reduces acne blemishes and the appearance of redness. Conclusion: Previously an underutilized and unpurified byproduct, AN is now the source to develop the first topical AN oil for cosmetic use with an activity profile that suggests it is effective for those with sensitive and/or acne prone skin.

Ranking of cadmium low amount measurement systems according to economic, environmental, and functional indicators using ELECTRE analytical method

Published on: 8th September, 2021

OCLC Number/Unique Identifier: 9244774024

Cadmium is one of the transition metals, known by the scientific name Cd. One of its main characteristics is the high toxicity, even in very little amounts. Cadmium is often released through industrial effluents, pesticides, chemical fertilizers, and the burning of fossil fuels. Since the presence of cadmium ions in the living organisms’ body, especially humans, can cause serious damage to the liver and pancreas, and also because its role in causing cancer has been proven, measuring very low amounts of this metal is of high importance. In the first step, this study has reviewed and analyzed common laboratory methods for measuring small amounts of cadmium. Then, according to economic, environmental, feasibility, speed, and accuracy factors, all available methods were evaluated using the ELECTRE technique. The results showed that the extraction methods using Dowex Optipore V-493 resin and extraction system in Triton X-114 surfactant, placed in the first and second positions.

Behavior evaluation of freundlich and langmuir isotherms in cadmium preconcentration using solid phase extraction method for linear and nonlinear numerical computational patterns

Published on: 8th September, 2021

OCLC Number/Unique Identifier: 9244773069

Cadmium is naturally present in the mineral cadmium sulfide which is a rare form of this element and the highest amount of cadmium is obtained from the extraction process of other minerals such as lead, copper and zinc. The release of this metal into the environment leads to widespread epidemiological effects. Therefore, measuring small amounts of this metal is also of particular importance. Small amount measuring methods of this metal are such as,preconcentration using solid phase extraction system using adsorbents. The main part of the preconcentration process is achieved by adsorption processes. In this study, the behavior of Freundlich and Langmuir adsorption isotherms for the capacity of TMON and IMNM adsorbents in cadmium adsorption has been evaluated by Power and Rational statistical distributions. At the end of the study, the constant coefficients of the Freundlich and Langmuir models were compared in both linear and non-linear modes. The results showed; the linearization method for the Kf coefficient of the Freundlich isotherm can cause errors equal to 41.6% in TMON adsorbent and 39.3% in IMNM adsorbent. Also, in parameter b, errors of 66.66% are obtained in TMON adsorbent and 32.45% in IMNM adsorbent.

A validated method for coumarin quantification in Meliloti herba and its ethanolic extracts using micellar thin-layer chromatography

Published on: 12th October, 2021

OCLC Number/Unique Identifier: 9305454757

A micellar thin-layer chromatography method for the quantitative determination and validation of coumarin in Meliloti herba and its ethanolic extracts was developed and validated. For achieving good determination, the mobile phase of 5 x 10-4 mol/L Tween-80 in a mixture propanol-2 – water (5:95 v/v) was used. Densitometric determination was carried out at 275 nm. The calibration curve was linear in the range of 0.1-2.5 μg per band. The proposed method is simple, rapid, precise and accurate; replacing hazardous solvents by greener ones correspond to the modern requirements in “Green chemistry” concepts. The obtained data can be used for the routine analysis of coumarin in medical plant and extracts.

Metabolic profiling and antibacterial activity of Eryngium pristis Cham. & Schltdl. - prospecting for its use in the treatment of bacterial infections

Published on: 3rd November, 2021

OCLC Number/Unique Identifier: 9331573236

Morbidity and mortality of the infected patients by multidrug-resistant bacteria have increased, emphasizing the urgency of fight for the discovery of new innovative antibiotics. In this sense, natural products emerge as valuable sources of bioactive compounds. Among the biodiversity, Eryngium pristis Cham. & Schltdl. (Apiaceae Lindl.) is traditionally used to treat thrush and ulcers of throat and mouth, as diuretic and emmenagogue, but scarcely known as an antimicrobial agent. With this context in mind, the goals of this study were to investigate the metabolic profile and the antibacterial activity of ethanolic extract (EE-Ep) and hexane (HF-Ep), dichloromethane (DF-Ep), ethyl acetate (EAF-Ep) and butanol (BF-Ep) fractions from E. pristis leaves. Gas Chromatography-Mass Spectrometry (GC-MS) was performed to stablish the metabolic profile and revealed the presence of 12 and 14 compounds in EAF-Ep and HF-Ep, respectively. β-selinene, spathulenol, globulol, 2-methoxy-4-vinylphenol, α-amyrin, β-amyrin, and lupeol derivative were some of phytochemicals identified. The antibacterial activity was determined by Minimal Inhibitory Concentration (MIC) using the broth micro-dilution against eight ATCC® and five methicillin-resistant Staphylococcus aureus (MRSA) clinical strains. HF-Ep was the most effective (MIC ≤ 5,000 µg/µL), being active against the largest part of tested Gram-positive and Gram-negative bacterial strains, including MRSA, with exception of Escherichia coli (ATCC 25922) and Pseudomonas aeruginosa (ATCC 9027) and (ATCC 27853). These results suggest that E. pristis is a natural source of bioactive compounds for the search of new antibiotics which can be an interesting therapeutic approach to recover patients mainly infected by MRSA strains.

Extraction of DNA from face mask recovered from a kidnapping scene

Published on: 7th January, 2022

OCLC Number/Unique Identifier: 9395237994

Deoxyribonucleic acid (DNA) extraction has considerably evolved since it was initially performed back in 1869. It is the first step required for many of the available downstream applications used in the field of molecular biology and forensic science. Blood samples is one of the main body fluid used to obtain DNA. This experiment used other body fluids such as saliva, sweat tears and mucus. There are many different protocols available to perform nucleic acid extraction on such samples. These methods vary from very basic manual protocols to more sophisticated methods included in automated DNA extraction protocols. This experiment used extraction kit (Zymo research). The DNA result from isolated saliva samples on the facemask range from 133.7, 213.6, 599.1 and 209.1 mg/ml. theoretically; such DNA is of much quantity and quality and can be used for forensic investigation when recovered from a crime scene. The DNA from isolated tears samples on the face mask ranges from 707.7, 202.5, 99.2, and 62.6 mg/ml. Theoretically, such DNA is of much quantity and quality and can be used for forensic investigation when recovered from a crime scene. The DNA from isolated tears samples on the face mask ranges from 615.3, 66.2, 78.5, and 68.2 mg/ml. theoretically, such DNA is of much quantity and quality and can be used for forensic investigation when recovered from a crime scene. Extracted DNA from saliva and sweat produced visible bands on agarose gel, mucous stain produce obscure band on agarose gel and the tears stain produce invisible bands. DNA from sweat satin, saliva stain, mucus stain and tears stain in face mask can be used as alternative for forensic investigation.

Genetic identification of three exhumed human remains at a hospital in Ghana: a forensic case report

Published on: 7th January, 2022

OCLC Number/Unique Identifier: 9395224000

DNA identification is very important in cases of high decomposition of dead bodies, in which the bodies cannot be identified by physical means.To compare the results of DNA typing, it is necessary to have related subjects with which to perform comparative analyses. Such tests are normally performed by comparing DNA profiles from people known to be immediate family members of the presumptive victim, such as parents or children because they share half of their genetic material with the unidentified.We report on how DNA analysis was used to solve a case of mixed-up bodies at a local mortuary in Ghana, West Africa. Two families and three buried human remains were in contention in this case. The first body (E9) was buried three months before exhumation. The second body (E11) was buried two and a half months before exhumation whiles the third body (E10) was buried a month before exhumation. Exhibit E5 was taken from an alleged child of the deceased, E11. Toenails of the exhumed bodies were sampled by a pathologist and used for DNA extractions using the QIAamp DNA Investigator Kit. Profiles from relatives were generated for comparison purposes. All samples gave a quality amount of genomic DNA after quantification. DNA was amplified with a GlobalFiler PCR amplification kit. Profiles from relatives were generated for comparison purposes.The human remains (exhibit E11) cannot be excluded as the biological father of the child (exhibit E5) because they share common alleles at all 23 genetic loci. The applicable combined paternity index was 17218125604.492 assuming a prior probability of 0.5. The probability of paternity is 99.99999999%. Based on this relationship testing, one of the bodies was successfully identified and handed over to the family for re-burial.

ems. Preliminary field tests may be used for screening the debris on the explosion site. They include commercially available explosive vapor detectors and chemical color tests. Like post-explosion residues, personal items suspected to contain traces of explosives and hand-swabs, are often heavily contaminated. It is therefore of major importance that the analytical procedures have to include good screening, clean-up, and extraction methods. The main explosives dealt with in this chapter include nitroaromatic explosives, such as 2,4,6-trinitrotoluene (TNT) and 2,4,6, N-tetranitro-N-methyl aniline (tetryl), nitrate esters, such as ethylene glycol dinitrate (EGDN), glycerol trinitrate (nitroglycerin, NG), and pentaerythritol tetranitrate (PETN), and nitramine explosives, such as 1,3,5- trinitro-1,3,5-triazacyclohexane, (RDX) and 1,3,5,7-tetranitro-1,3,5,7-tetrazacyclooctane (HMX), as well as mixtures containing one or more of these explosives. Additional explosives include triacetone triperoxide (TATP) and ammonium nitrate (AN), NH4NO3.

Plant molluscicide based on Smolevka white (Silene Latifolia) as prevention of pastoral helminthiasis of animals

Published on: 9th June, 2022

OCLC Number/Unique Identifier: 9538010281

Soft-bodied is the intermediate host of helminthiases, in the body of which several development stages of larval forms of helminths occur. There is the highest population density of mollusks in the areas of ruminant grazing, which leads to mass infection of animals with trematodes. To destroy the intermediate host of helminths in agricultural production, molluscicidal remedies of synthetic and plant origin are used. The work aimed to determine the molluscicidal effectiveness of a plant remedy based on Silene Latifolia in conditions of natural pastures. The material for work was the green mass of the plant S. Latifolia obtained in the warm season from roots, leaves, stems, flowers, and seeds. By grinding this plant, a powder with a particle size of 1-3 mm was obtained. Then, the powder was extracted with ethyl alcohol. The obtained product (concentrate) was an amorphous gel-like mass of dark green color with a specific smell and well soluble in water. Fieldwork in natural pastures was carried out on 5 biotopes with an area of 4-25 m2. Three species of gastropods were recorded from freshwater mollusks in the biotopes: Planorbis planorbis, Planorbarius corneus, Physa fontinalis, Lymnaea truncatula, and L. palustris. The results of experiments conducted in the conditions of pastures indicate a high molluscicidal activity of the studied plant agent on pond fish, intermediate hosts of trematodes pathogens. The effectiveness of the developed molluscicide on gastropods, when treated with a working solution (10.0 g/l) is from 98.1 to 100%.

Incidence, risk factors, and outcomes of acute kidney injury among hiv positive medical admissions at the Bamenda Regional Hospital

Published on: 16th June, 2022

OCLC Number/Unique Identifier: 9538011570

Background: There is a paucity of data on the burden of acute kidney injury (AKI) in hospitalized HIV-infected patients in Sub-Saharan Africa in the “test and treat” era.Objectives: To study the incidence, risk factors, and outcomes of AKI among HIV-positive medical admissions in a secondary hospital.Materials and methods: We prospectively screened adult HIV-positive patients who gave their informed consent and were admitted to the Bamenda Regional Hospital for AKI from February to June 2020. We excluded participants with Chronic Kidney Disease (CKD) Stage 5 and those with confounders of serum creatinine. On admission and after 2-7 days, we extracted a venous blood sample from each participant to evaluate serum creatinine and diagnose AKI. The participants were then followed up on until they were discharged or died. We measured the need for dialysis, access to dialysis, and renal recovery at three months for patients with AKI. The amended KDIGO 2012 criteria were used to define and classify AKI. The University of Bamenda’s institutional review board provided ethical approval.Results: A total of 206 participants (39.8% men) were enrolled, with a mean (SD) age of 45.71(13.13) years. On enrolment, 89.8% (n = 185) of the participants were on combination antiretroviral therapy (c-ART), with 81.6% (n = 151) on tenofovir-containing regimens. The WHO HIV clinical stages 3 and 4 were present in 81.5% (n = 168) of the individuals. The most common reason for hospitalization was opportunistic infections (69.8%; n = 142). AKI was found in 30.6% (n = 63) of the patients, with 58.7% (n = 37) of them being classified as KDIGO stage 3. A total of 12 (42.9%) participants out of the 28 in need, were dialyzed. AKI was independently associated with use of traditional medicines (aOR = 2.9; 95% CI 1.4-6.3; p = 0.006), WHO HIV stages 3 and 4 (aOR = 4.1; 95% CI 1.1-15.7; p = 0.038), hypotension (aOR = 3.3; 95% CI 1.4-7.8; p = 0.008) and low haemoglobin level ≤ 8.0 g/dl (aOR = 3.5; 95% CI 1.7-7.4; p = 0.001). The AKI group used to have a significantly higher mortality rate (42.9% vs. 16.1%; p < 0.001). Renal recovery was complete in 66.7% of the 30 survivors at three months, partial in 13.3%, and no recovery in 20% of the survivors.Conclusion: Despite the growing use of combination antiretroviral medication, significant immunosuppression is still common in hospitalized HIV-positive patients, increasing the risk of AKI and worsening prognosis. In this high-risk population, early detection of AKI with renal function monitoring may improve results.

Novel extractive visible spectrophotometric method for determination of antihypertensive drug irbesartan with sulfonephthalein acid dyes in tablets

Published on: 22nd June, 2022

Irbesartan (IRB) is one of the drugs used for the treatment of hypertension. The present work develops and validates two methods for the evaluation of irbesartan in bulk and tablets. Sulfonephthalein acid dyes, bromophenol blue (BPB), and bromocresol purple (BCP) were used to produce stable yellow ion-association complexes with the basic drug IRB in dry chloroform. The colored products are quantified spectrophotometrically at their corresponding λmax. The relation between the absorbed signal and the drug concentration was linear up to 45.0 μg mL-1 (n = 6, r ≥ 0.9998). LOD reaches 40 ng mL-1. The composition of the ion associates was found 1:1 by Job’s and mole ratio methods. Application of the suggested methods to dosage forms is presented with percentage recoveries ranging from 99.33% to 101.67%. The results of the analysis were validated statistically and compared with the official method. No interference was observed from common pharmaceutical adjuvants.

The protective potential of Carbonic Anhydrase VI (CA VI) against tooth decay in children: A systematic review of the literature

Published on: 2nd August, 2022

Carbonic anhydrase VI (CA VI) catalyzes the reversible hydration of carbon dioxide in saliva with possible pH regulation, taste perception, and tooth formation effects. Objective: The aim of this work was to undertake a systematic review regarding the relationship between the expression/activity of CA VI in saliva and in dental biofilm and caries experience. Study design: Five databases were searched until February 2020. The composition was based on the PRISMA statement and on the PICOS model. First author, year, subject characteristics, analysis performed, outcome, measures & variables were extracted. The used terms were “carbonic anhydrase VI”, “saliva”, “dental biofilm” and “dental caries”.Results: Five studies in the English language were selected for this systematic review and the main discussed topics were the expression/activity of CA VI in saliva and/or in the dental biofilm of children, and its relationship with dental caries. Conclusion: Salivary carbonic anhydrase plays an important role in the caries dynamics process since there is an association between the expression/activity of CA VI in saliva and the experience of caries. Thus, this protein can predict the risk of dental caries in young patients.

The “manna” extracted from the ash trees still cultivated in Sicily from mythical food to pharmaceutical and nutraceutical resource

Published on: 30th August, 2022

“Manna” is the product obtained from the solidification of the elaborate sap that comes out of the incisions made during the summer season on the stem and on the main branches of some species of the genus Fraxinus (Oleaceae). The cultivation of manna ash trees dates back to ancient times in Sicily and elsewhere ash trees – known as sacred trees, a symbol of abundance and therefore auspicious – was increasingly widespread until the middle of the last century. Subsequently, however, the crop underwent a progressive decline, remaining relegated to restricted areas of Sicily, in particular in the Madonie district (Palermo, Italy). In this brief review, the essential characteristics of the manna and the ash trees from which it is extracted are summarized. The aspects of the current productivity of manna in the Sicilian territory and the implications of a potential recovery and increase of an ancient craft, ash tree cultivation, are also reported in a perspective of sustainable development and green economy for the Mediterranean area and beyond. Finally, the authors remember what has been done to ensure the conservation not only of the active cultivation of manna ash but also of all the relative agro-biodiversity. The conservation of the living germplasm of the ancient cultivars recovered in the Madonie area (Palermo, Sicily) represents one of the most qualifying results.

Impact of coronavirus pandemic on safety and time of administration of subcutaneous immunotherapy among pediatric patients

Published on: 2nd September, 2022

OCLC Number/Unique Identifier: 9617323801

Introduction: Allergen immunotherapy is the only targeted therapy that can modify the natural course of allergic diseases. In pediatric patients, SCIT with aeroallergens is an effective treatment and should be considered as a preventive strategy in the treatment of allergic diseases, even though one of the major concerns about it is its safety. The main purposes of this study were to assess the safety of SCIT ultra-rush schedules with polymerized extracts in a pediatric population and to determine the impact of the COVID-19 pandemic on the safety and time of administration of subcutaneous immunotherapy among pediatric patients.Methods: A retrospective medical records review of patients under 18 years of age undergoing SCIT was made and re-scheduling due to restrictions imposed by the COVID-19 pandemic was recorded. Results: A total of 192 pediatric patients were included. Fifty-nine (31%) had local reactions and systemic reactions were not reported. In March 2020, the first case of COVID-19 was diagnosed in Portugal and all non-urgent appointments and procedures were postponed. In our group of pediatric patients, 43 (22%) were referred to primary care, 38 (20%) stopped AIT definitively and 111 (58%) maintained administrations in the hospital. Only 2 (2%) of them had reactions upon reinitiation. Conclusion: In this study, the ultra-rush protocol using polymerized extracts was safe in pediatric patients. Although the effectiveness of AIT may be compromised due to prolonged suspension of the treatment, it is important to note that despite longer interruptions, administrations may continue without compromising safety, maintaining shorter visits and a lower number of injections.

Synthesis of citric acid using novel Aspergillus niveus obtained from agricultural wastes

Published on: 13th September, 2022

Fungus belonging to the genus Aspergillus is considered highly important in the production of various types of enzymes and organic acids. Aspergillus species produce organic acids such as citric acid, itaconic acid, and malic acid, which are one of the most important alternate techniques for chemical processes. Citric acid is an important component in the manufacturing process of food and beverages, pharmaceuticals, cosmetics, toiletries, detergents, and other industries. In this work, A.niveus was isolated from the agricultural waste collected in Kotagiri, The Nilgiris, India. Submerged batch fermentation with a range of low-cost substrates, such as wheat flour, corn starch, and sweet potato, was used to successfully synthesize citric acid by the isolated fungus. In addition, production-related factors such as substrate concentration and incubation time were optimized. The maximum yield of citric acid was produced using A. niveus from corn starch at a concentration 7of 120 g/L after 168 hours at pH 3.2. Furthermore, with a degree of extraction of 91.96, citric acid was extracted from fermentation.

Determination of the in vivo activity of leaves extract of Zanthoxylum Chiloperone var. Angustifolium (Tembetary hú) orally and intralesionally administered to BALB/c mice experimentally infected with Leishmania

Published on: 23rd November, 2022

Natural products are becoming increasingly important as an unlimited source for obtaining chemical substances with possible pharmacological potential. Current existing drugs for the treatment of cutaneous leishmaniosis produce major side effects; therefore the search for new drugs is justified. The stem bark of Zanthoxylum chiloperone var. Angustifolium Engl. (Rutaceae) is traditionally used in Paraguay for its antiparasitic properties. The leaf extract was evaluated for the first time to determine its leishmanicidal activity in BALB/c mice infected with amastigote forms of Leishmania amazonensis (PH8). The mice were treated orally with the extract at three concentrations (100, 50 and 10 mg/mL), intralesional (50 mg/mL), and subcutaneously using glucantime as a control (100 mg/mL). The percentage of decrease in parasite load was measured and with intralesional 50 mg/kg a reduction of 72% occurred, with the reference drug (Glucantime) a reduction of 62% was obtained with the same oral dose a reduction of 50%, while with an oral dose of 10 mg/mL the percentage of reduction was 55%. When the oral dose was increased to 100 mg/mL, the reduction percentage of the parasitic load was only 16%. These results indicated that the leaf extract of Z. chiloperone var. angustifolium Engl. at low oral concentrations (50 and 10 mg/mL) had very good activity against L. amazonensis, and it was even more efficacious intralesionally at 50 mg/mL but at the oral dose of 100 mg/kg has very reduced antiparasitic activity. This study showed the efficacy of the extract leaves of Z. chiloperone in reducing the parasite load in an in vivo test, so its use as a potential leishmanicidal could be suggested to develop and evaluate new drugs for the oral treatment of leishmaniosis disease with fewer side effects and lower cost.

Evaluation of pulp and paper-making potential of Acacia melanoxylon based on chemical composition grown at Chencha, Ethiopia

Published on: 23rd November, 2022

The study aimed to examine the chemical composition of Acacia melanoxylon wood as a potential raw material for pulp and paper manufacturing. Samples of Acacia melanoxylon were taken systematically based on tree height at the bottom (10%), middle (50%), and top (90%) of market height. The sample was sorted, dried, milled, and sieved, and all chemical compositions were determined by the standards outlined in ASTM except cellulose and hemicellulose, which were determined by the Kurschner-Hoffer and alkali extraction methods, respectively. The results of the study showed that the overall average values of chemical composition along tree height levels were 45.02%, 21.94%, 23.79%, 5.52%, 3.24% and 0.48% for cellulose, hemicellulose, Klason lignin, hot-water solubility, alcohol-benzene extracts, and ash content, respectively. Except for hot-water extractives, the chemical composition of the bottom and top portions differed significantly. Generally, this study suggests that the chemical composition of Acacia melanoxylon wood is well suited for pulp and paper production.

Produce starch-based bioplastic from different renewable biomass sources

Published on: 28th December, 2022

Due to the adverse environmental impacts of synthetic plastics, biodegradable plastics development for both industrial and commercial applications is essential for the present scenario. In addition to the non-degradability of petroleum-based plastic and its impacts, so it is very important to find an alternative to petroleum-based plastic. Starch-based bioplastics are an excessive substitute for petroleum-based plastics due to their significant properties compared with natural sources. This research aims to formalize five new formulas of bioplastic by combining two sources of starch, extracted from various biomass sources, its properties and comparison between them. The moisture content shows 2.07% and 0.984% for samples F and B respectively and that indicates that the samples which contain a high amount of corn starch have less moisture content. The highest results of biodegradation percentages were 68.27% and 52.6% which are for samples A and D respectively, and the lowest biodegradation percentage were 34.33% and 31.29% which are for samples F and B respectively.
