Authors: Meguellati H. , Ouafi S. , Saad S. , Harchaoui L. , Djemouai N.
Published: October 2022

The valorization of Teucrium polium L. subsp. geyrii Maire, an endemic medicinal plant of Algeria was attempted. A somatic embryogenesis protocol was developed and two types of cell suspensions (brown and gray suspensions) were obtained. Weight evolution of the two suspensions revealed a latency phase, an exponential growth phase and a final stationary phase which was directly followed by cell degeneration at the end of the third month of culture. Total polyphenols estimation showed that brown suspensions contained the highest absolute content. The production of flavones-flavonols, anthocyanidins and C-glycosides in the two types of cell suspensions remained low during the cell growth phase while it became active later during the stationary phase and was found to be more intense at the end of cell growth. HPLC profiles indicated that the synthesis of the various phenolic fractions (flavones-flavonols, anthocyanidins and C-glycosides) took place unevenly in the two cell suspensions.

Authors: Kranthi Kumar G. , Silpa D. , Raghu Ram M.
Published: October 2022

21 rhizobacterial strains were isolated from root nodules of Vigna trilobata (L-Verdc) plants raised in soils collected from geographically different areas in Andhra Pradesh, India. The identification of rhizobacteria was done by biochemical and by 16 S rDNA sequencing analysis along with accession numbers (Rhizobium sp. MRR 106, KC428655 and Rhizobium sp. MRR 123, KC503884). Detection of siderophore production by microorganisms in solid medium is the universal Chrome Azurol’ S (CAS). Agar plate assay method was used for this study. Out of 21 strains, only 7 showed the siderophore production. Of the 4 siderophore positive, two strains Rhizobium sp. MRR 106 and Rhizobium sp. MRR 123 are hydroxamate type and rest of them are catechol type. Siderophore production was observed at 24 h of incubation and it reached maximum at 144 h of incubation. Qualitative and quantitative estimation of hydroxamate type of siderophore production shows much difference along with iron concentrations up to 20 to 80 μM in Rhizobium sp. MRR 106 and Rhizobium sp. MRR 123. Various carbon and nitrogen sources greatly influenced the siderophore production. Among them, glucose (1%) and glycine (0.1%) were found to be the best for siderophore production.
Callus induced from Stevia rebaudiana Bertoni. leaf used as a substitute of artificial sweetener
Authors: Sahay Sudha , Braganza Vincent
Published: October 2022

Stevia rebaudiana Bertoni is an anti-diabetic plant for which a protocol for rapid plant multiplication from nodal segments and through callus induction from leaf explants was developed with a short incubation period. Maximum callus induction (~100 %) was obtained on modified MS medium incorporated with BAP: NAA (1:3 mg/L) within two to three weeks of incubation under controlled growth room environmental conditions. In the presence of specific concentration/combination of plant growth regulators, the calli obtained from leaf explants were of different colours viz. soft/creamy or off-white, shiny/green, hard/brown and thick/black having varying total sugar content. The present findings deal with induction of callusing in Stevia leaves to achieve rapid callus multiplication. We have also standardized the protocol for plantlet regeneration from Stevia nodal segments where large sized leaves were obtained after 2 weeks of inoculation and the sterile leaves of these regenerated plantlets were used to induce callus. The developed protocol can be utilized for mass production of callus material on a large scale, independent of seasons i.e. external environmental conditions and its dry and purified powdered formulation can be used as a substitute for sugar on a commercial scale.

Authors: Mishrikoti Shayistanaaz M. , Isaq Farheen , Kamble Geetanjali R. , Kulkarni Badarinath D.
Published: October 2022

Neurodegeneration corresponds to any pathological condition primarily affecting neurons and resulting in their death. Neurodegenerative diseases affect specific subsets of neurons in specific functional anatomic systems. Apart from neuronal dysfunction and death, neurodegenerative diseases are associated with fundamental processes such as oxidative stress and excitotoxicity. There are various neurodegenerative diseases, amongst them around one billion world’s population suffers from Alzheimer Disease, Parkinson Disease and Amyotrophic Lateral Sclerosis and hence these are the most observed disorders. Though pharmacological drugs are used in the treatment of these diseases, these drugs are associated with mild to severe side effects and are expensive as well. Plants possess therapeutic properties which exert beneficial pharmacological effect on humans. In ancient times, people were totally dependent on green plants for the treatment. Each medicinal plant consists of several important components playing a vital role in treating or preventing various kinds of diseases. There are herbs which have anti-inflammatory and antioxidant activities useful in the treatment of neurodegenerative diseases. Thus, this review summarizes information about the applications of various plants and their therapeutic properties that could be used in the treatment of neurodegenerative diseases.
A Broad Review of Plant-Derived Bioactive Peptides to combat Pathogenic Outbreaks - A Future Peptide based Therapeutic Approach
Authors: Poojasri S. , Ramya A.K. , Annathai P.
Published: October 2022

Cyclotides are plant-derived proteins belonging to globular micro proteins (≈ 25 to 30 amino residues long) class with a cyclized head-to-tail backbone and its structure stabilized by the presence of cystine knot by three disulfide bonds. Cyclotides withstand biochemical degradation and are heat resistant compared to other types of peptides. In addition, conserved amino acids in the region of the cystine knot showed strong tolerance towards genetic errors. Interestingly, their topology makes them suitable for oral administration and cellular membrane transportation via crossing cell membranes. Cyclotides have been strongly potent candidates for designing anti-viral plant-derived peptides to combat newly emerged and reemerged outbreaks and also making them natural scaffold for drug development template. From the recent reports, cyclotides have been genetically engineered to study protein-peptide interactions for targeted drug delivery methods. In this study, we are undertaking a review on the discovery, history, role of cyclotides in Plant's defense mechanism and tools to the characterization of cyclotides, membrane binding efficiency of cyclotides, antiviral property and cyclotide scaffold designing.

Authors: Sahay Aarya , Tomar S. Rajesh , Chauhan S. Pallavi
Published: October 2022

Wound infections are generally difficult to manage and treat. Thus in this review, antimicrobial susceptibility of wound pathogens is described. Antibiotics susceptibility of wound pathogens was found to be sensitive to several antibiotics like amikacin, gentamicin while most of them show resistant behaviour towards antibiotics like ciprofloxacin. Some microbial strains are resistant while some show sensitivity towards antimicrobial agents depending upon several physiological factors. This review has shown that the wound healing process is mainly slowed down by having either a higher microbial load or may have a certain resistance mechanism against selected antibiotics. Thus, this review highlights alternative therapeutic approaches like susceptibility testing, culture-based bacterial diagnosis including antimicrobial resistance testing which needs further exploration.

Published: October 2022

We investigated bacterial diversity in Tricholoma matsutake shiro and isolated the beneficial bacteria that inhabited matsutake shiro for using it in cultivation of the pine mushroom. The bacterial strain, the growth promoting bacterium of matsutake, was isolated using a culture-dependent method from the shiro. The strain was characterized by microscopic and metabolic techniques and identified by sequencing of PCRamplified 16S rRNA gene fragments as Micrococcus luteus. Internal transcribed spacer (ITS) specific primer method was used to confirm the presence of matsutake in soil samples. Total cell numbers in January and March (up to 8–12×106 cells g-1 dry soil) in the shiro were lower than those in June and September (15–18×106 cells g-1 dry soil). The bacterial population was 200–300 folds lower in the shiro than those in the non-shiro sample. The total cell number was 8–18×106 cells g-1 dry soil, the culturable bacteria count being 1.0–2.5×105 CFU g-1 dry soil, in the shiro. The results showed that matsutake coexisted with different bacteria such as those belonging to the genera Bacillus, Burkholderia, Pseudomonas, Micrococcus and Agrobacterium in shiro. Interestingly, the genera Streptococcus, Arthrobacter, Staphylococcus and Flavobacterium were found in non-shiro, but not in the shiro.
The Implications of Smoking on Lipid Peroxidation and Serum Antioxidant Status in Young Smokers with Coronary Heart Disease
Authors: Nath Dinesh , Shivasekar Meera
Published: October 2022

Cigarette smoking is one of the leading causes of heart disease. Cigarette smoke contains oxidants playing a major role in oxidative stress by lowering antioxidant capacity and by increasing the level of lipid peroxidation. The study aims to estimate the total antioxidant capacity levels, lipid peroxidation and its relation to cardiovascular disease in young smokers. The study contains three groups. Group1 includes 120 healthy controls as nonsmokers, group2 includes 120 young active smokers with coronary heart disease (CHD) and group3 includes 120 young active smokers with diabetic CHD subjects who were attending the SRM Medical College Hospital in Tamil Nadu for cardiology and medicine. The Total Antioxidant Capacity and lipid peroxidation especially measured as malondialdehyde (MDA) was determined using a spectrophotometric technique. Enzyme-linked Immune Sorbent Assay was used to measure oxidized LDL (ox- LDL)" and "high-sensitivity CRP (hs-CRP). The total antioxidant capacity of smokers was found to be significantly lower than those of healthy controls p<0.0001. On the other hand, MDA, ox-LDL and hs-CRP concentrations were considerably higher in smokers than healthy controls p<0.0001. Interestingly smoking burden and smoking intensity also show a significant correlation with antioxidant capacity, lipid peroxidation (MDA) as well as with ox-LDL. The study concludes that cigarette smoking reduces the concentration of total antioxidant required for free radical scavenging which enhances the rate of lipid peroxidation and is one of the risk factors for CHD observed in smokers.

Published: October 2022

Spodoptera frugiperda is a major pest causing a huge economical loss to many crops. In this present study, S. frugiperda larvae were collected from maize field and grown on natural and artificial diet. Steinernema carpocapsae was stored by using two different storage methods and tested on S. frugiperda larvae for mortality. Larvae grown on natural diet showed 58 -78% mortality whereas on artificial diet, 30- 65% mortality was recorded in 24 - 48hrs in glycerol and SA-AG beads were stored at 1000IJs. Haemolymph and midgut were collected from infected larvae maintained grown on natural diet for performing biochemical assays. THC showed decreased count in larvae at 250IJ concentration. Total protein level was high, infected with glycerol stored IJs. Phenoloxidase, SOD, POD, GST and CarE assays showed low activities at all IJs concentrations. LPO levels and CAT activities showed increase in beads storage and in fresh IJs at 1000IJs concentration. Cyt P450 showed similar activity when compared with fresh IJs. Results of antioxidant and detoxification assays conclude that fresh and SA-AG beads stored IJs have similar efficacy (nearly equal effect) in infecting S. frugiperda.

Published: October 2022

The aim of this study was to detect and evaluate the extracellular keratinase enzyme production by Arthroderma multifidum TKKASa (KU560574), a keratin-degrading fungus isolated from the keratin contaminated soil of Rajasthan, India. This study focused on the evaluation of the effect of keratin substrates, pH, incubation days, temperature and metal ions for keratinase enzyme production. The highest enzyme production by A. multifidum was observed on chicken feathers (56.25±0.69 U/mL) followed by human hair, animal hair and human nail clippings. The maximum keratinase production by A. multifidum was achieved at 40˚C with 58.80±0.98 U/mL enzyme activity and pH 8.0 (56.65±0.85 U/mL) after 12 days of fermentation. The addition of metal ions in basal salt media resulted in the decrease in enzyme production. This study reports keratinase production by A. multifidum and the high efficiency on the chicken feather degradation in comparison to human nail clipping, animal hair and human hair degradation. Its potential use is in biotechnological processes such as biodegradation of keratin wastes, eco-friendly dehairing and poultry feed production.
Effect of mutations on the structure of Mycobacterium tuberculosis KatG protein and interactions with Isoniazid - An in-silico study
Authors: Falcao B. , Dsouza N. , Gokarn K.
Published: October 2022

Fight against tuberculosis (TB) is still ongoing in India. The problem of drug resistance in Mycobacterium tuberculosis (M.tb) has obligated the need of studying key enzymes involved in drug interaction. One of the known M.tb enzyme targets for the primary drug isoniazid is catalase-peroxidase (KatG). In this study, we induced mutations (observed in clinical samples) at specific locations around the catalytic binding site of KatG protein and elucidated the impact of these mutations on the protein structural stability, secondary structure deformation and binding interaction with the drug ligand. It is clear from this study that mutations near the heme region have impacted the structure of the protein and the binding pattern with the drug. It can be hypothesized that this change leads to inhibition of KatG protein catalase and free radical generation activity. This could impact the KatG-Isoniazid interaction and overall make the bacteria resistant to the drug.

Authors: Salsinha Yustina Carolina Febrianti , Dewi Kumala , Arryanto Yateman
Published: October 2022

The inefficient absorption of minerals by plants can be avoided by using slow-released fertilizers. This research aims to test the efficiency of Fe-composite as a slow-released fertilizer in supporting shallots (Allium cepa L. ‘Bima Brebes’) growth and yield at the early stage of the reproductive phase. This research was conducted with shallots plant treated with the two groups including a control group and treatment group. The control group consists of control 1 (without NPK), control 2 (standard NPK), control 3 (50 ppm FeCl3 + standard NPK), while the treatment group consists of varied alginate: zeolite (3:1) Fe composite in the concentration of 50 ppm, 100 ppm, 150 ppm, 200 ppm and 400 ppm. The plant height, number of leaves and shoot fresh and dry weight were observed higher at the concentration of 150 ppm Fe-composite. Plants treated with concentrations exceeding 150 ppm tend to experience decreased growth, photosynthetic rate and low bulb yields. The analysis of starch content and Fe content in the bulbs shows that the plant treated with 150 ppm Fe-composite tends to have a higher content of both starch and Fe but is not significantly different from the treatment of 100 ppm Fe-composite. In this study, the use of Fe-composites affects the growth and yield of shallot with the optimum concentration that supports the growth and the largest tuber size in shallot is 150 ppm alginate: zeolite (3:1) Fe composite.

Authors: Uprety Sophiya , Khadka Anjita , Shrestha Dhruba
Published: October 2022

It is necessary to significantly accelerate the progress for optimal young child feeding practices in order to attain global nutrition goals and targets. Innovative and compelling communication approaches should be explored and tested to change social behaviours towards nutrition. A concept promoted in Nepal known as Poshan Nanglo (Nutrition Tray), is an interactive demonstration of locally available and nutritiously diverse foods.

 Using qualitative methodology, this study adopts the phenomenology method to understand preferences and perceptions of Poshan Nanglo among mothers of young children. A total of 305 mothers of children aged 6 to 23 months were interviewed from September 2019 to January 2020.  90%preferred Poshan Nanglo over printed materials. Three themes emerged: a simple and an easy way to learn, the use of real foods help to understand better and it is a practical approach.

 Thus mothers preferred and appreciated Poshan Nanglo to improve their understanding of good child feeding practices. These mothers also showed improvements in relating the importance of locally available nutritious foods for optimal dietary diversity. Approaching behaviour change should be informed and shaped by the beneficiaries’ interests and preferences. As a simple and sustainable approach in communicating about dietary diversity and good nutrition, Poshan Nanglo has wide relevance and potential.

Published: October 2022

Introduction: It has been shown that the contribution of beverage energy to total energy intake may increase the risk of diseases in various countries. The aim of this study is to evaluate the relationship between the consumption of added sugar from beverages and nutritional status, anthropometric measurements and biochemical blood parameters in adults.

 Materials and Methods: This study was designed as an analytical and cross-sectional study  and conducted on 100 adult females aged 18-65 who applied to the private diet outpatient clinic in Istanbul/Turkey between November 2020 and April 2021. The demographic characteristics of the individuals were applied to the participants using the food frequency questionnaire, eating habits, physical activity habits and beverage consumption frequency questionnaires.

 Results: The mean age of the women in the study was 31.8 years . Total energy intake from beverages in women over 25 years old was found to be 145.3 kcal and significantly lower. All women in the study consumed tea and coffee. The consumption rate of all beverages except energy drinks was found to be higher in the younger adults. A positive correlation was found between the results of an insulin resistance test and the total amount of added sugar from the beverages consumed (r=0.297 p=0.043). 

 Conclusions: Lower levels of consumption of sugar-sweetened beverages may result in a lower burden of chronic diseases. Future studies should explore consumption patterns of added sugar beverages and individual-level associations with such consumption.
Energy: life, power, and livelihood
Authors: Wahlqvist Mark L.
Published: October 2022

We and our habitat are forms of energy, endowed with life, and irrevocably earthlings. A cosmological-to-locality appreciation of energy in food and nutrition science, practice and policy is overdue. Our livelihood, and any function we have, are energy dependent, as is planetary habitability. Energy cognisance has become an existential necessity in an increasingly self-destructive ‘anthropocene’ era when our own energy equilibrium is compromised. This is manifest in destruction and loss of our ecology, our livelihood expectations, and practices, and, in turn, our wellbeing and health. Most problematic has been the domination, skewing and loss of biomass caused by humans, both their over-population of the earth, and their exploitation of its natural resources. These resources provide fuel for warmth, cooking and transport, textiles, and clothing; are subject to land and aquatic harvest, are replaced by dwellings and infrastructural buildings, and yet are recreational assets. Wastage has been of scant regard. Energy misuse besets the entire food system. This has followed the development of the wood and coal-fired steam engine, the advent of gasoline powered internal combustion engines, use and transmission of electricity, and an insatiable arms industry. Now, we are at the brink of extinction. Profiteering and conflict over energy control has fostered unfettered industrial materialism, a major extinction risk factor. Not only is energy the power we need, but it has also underwritten the powerful. Can we be sufficiently insightful and collaborative to change this energy trajectory and survive healthfully on a habitable planet? Individuals, households, and communities, as opposed to unaccountable monopolies, could achieve control of the energy systems on which our livelihoods depend and render them sustainable, accessible, and affordable. Interconnected food and energy system ownership could be devolved to ‘The Commons’ as a cooperative, sustainability strategy. The social momentum and appropriate technology for energy conservation, renewability and personalisation is now available for mobilisation to address our food, nutrition, and health insecurity.
Can Clinician-Stabilization with Hand-Held Dynamometry Yield a Reliable Measure of Knee Flexion Torque?
Authors: Larson Daniel , Lorenz Daniel , Melton Brittany
Published: October 2022

Background

Assessment of knee flexion torque is a relevant clinical measure following various injuries and surgeries to determine progress in rehabilitation and inform decision making. A variety of methods using hand-held dynamometry have been shown to be reliable in obtaining this measure, and typically require a means of external fixation or stabilization. Clinically efficient methods of reliable clinician-stabilization are sparse in the literature.

Hypothesis/Purpose

Determine inter and intra-rater reliability of two clinically efficient methods of assessing isometric knee flexion torque using hand-held dynamometry with clinician-stabilization. The hypothesis was that each method would yield good to excellent reliability.

Study Design

Cross-Sectional Study

Methods

Twenty healthy individuals were assessed by two clinicians on two separate days. During each session, knee flexion torque was assessed with hand-held dynamometry with two methods: 1) in the seated position with the hip and knee flexed to 90 degrees while the clinician stabilized the dynamometer between the participant’s leg and table and 2) in prone with the hip at 0 degrees and knee at 90 degrees while the clinician assumed a stride stance with elbows locked in extension to stabilize the dynamometer on the participant’s leg. Inter and intra-rater reliability were determined for each method.

Results

ICC values were 0.88-0.94 and 0.77-0.90 for inter and intra-rater reliability respectively with the seated method. The prone method yielded ICC values of 0.84-0.96 and 0.89-0.94 for inter and intra-rater reliability respectively. MDC values ranged from 30-62% with the seated method and 21-40% with the prone method.

Conclusion

Inter and intra-rater reliability were good to excellent for assessing knee flexion torque with hand-held dynamometry using both the seated and prone methods with clinically efficient clinician-stabilization approaches. The prone method may be more sensitive to detecting change over time due to lower MDC values.

Published: October 2022

this artificial intelligence robot uses a mini-computer to operate it and uses mechanical movement like a four-wheeled vehicle with a 2WD drive system. In this article, a control strategy of the AGV robot will be shown and implemented to detect the location. This research Uses OCR (Optical Character Recognition) for the OpenCV library itself which has been enhanced/modified. This enhanced OCR is the main library used in text recognition. This research produces very accurate text detection compared to the default OCR that was previously used on the AGV robot in our university. After the process of reading this text is passed, it will produce text previously read through the camera which will then provide output in the form of text where the AGV robot is located. After the reading is validated, the AGV robot will move to the next point until it returns to its starting point. Based on hardware implementation through testing in the AGV laboratory with artificial intelligence, it can work according to the algorithm and minimize reading errors with a 95% success rate.

Sampai saat ini dalam pengelolaan data pada perpustakaan seperti data peminjaman dan pengembalian buku di tiap- tiap sekolah masih sering dilakukan secara manual. Yang dimaksud dengan manual disini yaitu pencatatan data masih dicatat didalam buku. Dengan demikian proses ini sering menglamai kendala pada saat petugas melakukan penyimpanan dan pencarian data buku baik saat transaksi peminjaman, pengembalian dan pengecekan mengenai denda atau sanksi. Masalah ini dapat diatasi yaitu salah satunya dengan merancang suatu system berbasis web menggunakan bahasa pemrograman PHP serta basis data MySQL yang berfungsi untuk memudahkan petugas perpustakaan dalam melakukan olah data . Tujuan dari sistem ini yaitu untuk mengubah cara pengelolaan data-data perpustakaan dari cara manual menjadi otomatis dengan menggunakan komputer. Adapun metode yang dipakai dalam merancang sistem ini yaitu dengan menggunakan metode waterfall. Metode tersebut dilakukan dengan tahapan-tahapan melakukan analisis kebutuhan, desain model sistem, penulisan kode program, pengujian sistem, serta pemeliharaan. Untuk tahap pengujian akan dilakukan dengan user acceptance testing yaitu dengan melakukan pengujian black box. Berdasarkan hasil pengujian black box yang telah dilakukan yaitu diperoleh hasil bahwa semua fitur-fitur yang ada pada sistem semuanya berjalan dengan normal.
