Measles is a highly infectious viral disease that affects the respiratory tract. Even though the vaccine was developed, it still concerns a group of populations in the world. Andrographis paniculata is locally called Green chiretta, an annual herbaceous plant that has numerous medicinal properties. The thirteen compounds from Andrographis paniculata were virtually docked with the major receptor proteins of measles i.e. SLAMF1, CD 46, Nectin-4, Fusion protein and Haemagglutinin protein using the PatchDock program for molecular docking. The results obtained were analyzed and the docked structures are visualized using PyMOL software. Based on PyMOL analysis of all ligand interactions with measles virus host cell receptors and viral proteins among thirteen bioactive components, tetradecanoic acid was found to interact strongly with all measles virus proteins forming at most five hydrogen bonds and had the best geometrical fit to the measles receptors.
Interaction between Nitric Oxide and Hydrogen Sulfide in Abiotic Stress Challenged Plants
Authors: Chandrakar Vibhuti , Kumar Meetul , Keshavkant S.
Published: February 2022

Nitric oxide (NO) and hydrogen sulfide (H2S) are two versatile gaseous molecules which play myriad roles in the growth and development of plants. They play an important role in signal transduction process in plants exposed to various environmental stresses. Signal transduction and various antioxidant strategies are vital for the management of abiotic stress imposed alterations in plants. These two secondary messengers neutralize the cell perturbations caused by stresstriggered over produced reactive oxygen species. Study of crosstalk between NO and H2S reveals the functional importance of proteins regulated during Snitrosylation and S-sulfhydration respectively, the two major signal-dependent post-translational protein modifications. Also, NO and H2S decrease the toxic impacts of reactive species by triggering the signal transduction process, enhancing antioxidant enzymes, stimulating other signaling molecules and regulating the transcript levels of different stress-responsive genes. This review mainly emphasizes on the roles of NO and H2S in responses of plants to abiotic stresses and reveals the crosstalk involving NO and H2S in stress tolerance mechanisms.

Authors: Suriya Narayanan S. , Suresh P.K.
Published: February 2022

Wound healing models are used as very important tools to test and study the new therapeutic approach in wound treatments. The present manuscript details different types of surrogates for the in vivo, human wound healing process based on different approaches (in vitro, in-vivo, ex-vivo, in-silico methods and animal models). The appropriate selection of a wound healing model is an important tool for wound healing research as it aids in the understanding of the wound healing mechanisms in detail. Also, this strategy enables the experimenter to focus on each stage of wound healing and aids in the evaluation of the wound healing methodologies in preventing the wounds; enhancing the healing process or in prevention of scar formation. The thorough understanding of the appropriate wound model will aid in evaluating the pathophysiology of the wounds, better strategies in the treatment modes, formulations for enhanced wound healing and limit abnormal scar formation. The understanding of both acute and chronic wounds healing mechanism has significantly improved by adopting these models along with the advent of new wound healing products, wound healing developments and advanced wound care.

Authors: Nanda Satyabrata , Kumar Gagan , Hussain Sajid
Published: February 2022

Molecular markers are one of the expandable inventions in agricultural science. After decades of their introduction, these still are an integral part of crop genotyping and crop improvement. The present scenario offers to choose from different molecular marker types based on their principle, methodologies and extent of applications. Several markers have been used to identify and map abiotic stress related genes and quantitative trait loci (QTL) onto the chromosomes of different crops. The genetic mapping of these identified genetic elements by using different markers provides the scope of selective breeding in the agricultural crops to tackle abiotic stresses. Moreover, recent progress achieved in genetics, molecular breeding and genomic selection has facilitated a comprehensive understanding of the molecular markers and unlocked new insights into marker-assisted breeding. The advent of new technologies like association mapping (AM) and genome-wide association studies has unveiled the highthroughput application of molecular markers. In this review, a focused representation of the use of different molecular markers in the identification of tolerant crop genotypes and associated genes/QTLs against major abiotic stresses, including salinity, drought and temperature has been provided. Additionally, the application of molecular markers in AM and AM-based breeding of some important agricultural crops has been discussed.
The genetic complexity of anorectal malformations
Authors: Prasad Bheem
Published: February 2022

Anorectal malformations (ARMs) are a heterogeneous group of congenital anomalies having an incidence of 1 per 5000 live births. ARM is among the most common surgically treated congenital anomalies. The genetic causes of anorectal malformations are complex and varied including chromosomal aberrations, singlegene disorders and phenotype with multifactorial inheritance. However, the exact aetiology remains largely unknown. It can be syndromic or nonsyndromic, sporadic, or familiar with a different mode of inheritance. Genetic information can provide a deeper understanding of genotype-phenotype correlation, disease nature and prognosis of the anorectal malformations. This review provides an overview of the genetic causes associated with ARMs. More emphasis is given to the monogenic syndromes with a brief overview of associated anomalies which play an essential role in genetic diagnosis, management and prevention strategies.

Published: February 2022

Bisphenol-A (BPA) is ubiquitously present in the environment and consumer products and is a crucial environmental contaminant known to cause significant health risks to various organisms. The present study aims to evaluate the genotoxicity effect of BPA in developing chick embryos. Fertile chicken eggs were treated with increasing concentrations of BPA (1, 10, 20, 30, 40 and 50 mM/egg) on embryonic days (ED) 8, 9 and 10. On ED11, the number of viable embryos was recorded and LD50 values were calculated for 24 h (ED 10), 48 h (ED 9) and 72 h (ED 8). HET-MN (Hens egg test for micronucleus assay) and comet assay were performed on the 11th-day to evaluate the cytotoxicity and genotoxicity potential of BPA. Experiments were performed in three different time points i.e. 24 h, 48 h and 72 h of exposure. Results showed an increased mortality rate in a dose and time-dependent manner. Significant alterations of cellular dynamics erythropoiesis and PCE/NCE ratio were observed. Also, significant induction of total MN and other nuclear abnormalities was observed. A decrease in head DNA content, increase in tail DNA, olive tail moment and damage indexes were detected upon exposure. Thus, the results confirmed the genotoxic and cytotoxic potential of Bisphenol-A that caused genetic alterations extensively during the early development of embryos.

Published: February 2022

Varicella is a common, benign and self-limiting disease. It is related to hepatitis and malfunction/failure of the liver. This study was designed to assess Varicella-Zoster Virus/ Hepatitis C Virus (VZV/HCV) co-infection on the levels of liver enzymes. A total of 88 blood samples regardless of Hepatitis C Virus positivity were collected. The age and sex of the sample population are included in the demographic statistics. HCV-RNA was detected by RTnested PCR and VZV-DNA was identified by nested PCR in all the sera. Approximately 27 patients were positive for HCV and VZV co-infection. Liver function was also tested on the basis of parameters such as Aspartate Amino Transferase (AST) and Alanine Amino Transferase (ALT). Infection with HCV and VZV is more prevalent in the 34-55 age group tested by nested-PCR and liver function tests based on Alt and AST levels using qualitative test kits. The ALT and AST levels were high 102 and 99.6 IU/L in co-infected cases as compared to 35 and 32 IU/L in normal cases without HCV, HIV and VZV. The study results indicate the impact of VZV in the abnormality of liver function. This study concludes that coinfection with HCV/VZV can be seen as a highrisk category for the development of liver disease where long-term outcomes of the disease should be controlled.

Published: February 2022

Efficient and timely testing has taken center stage in the management, control and monitoring of the current COVID-19 pandemic. Simple, rapid, cost-effective diagnostics are needed that can complement current polymerase chain reaction (PCR)-based methods and lateral flow immunoassays. Here, we report the development of an electrochemical sensing platform based on single-walled carbon nanotube screen-printed electrodes (SWCNT-SPEs) functionalized with a redox-tagged DNA aptamer that specifically binds to the receptor binding domain (RBD) of the SARS-CoV-2 spike protein S1 subunit. Single-step, reagentless detection of the S1 protein is achieved through a binding-induced, concentration-dependent folding of the DNA aptamer that reduces the efficiency of the electron transfer process at the electrode surface and causes a suppression of the resulting amperometric signal. This aptasensor is specific for the target S1 protein with a dissociation constant (KD) value of 43 ± 4 nM and a limit of detection (LOD) of 7 nM. We demonstrate that the target S1 protein can be detected both in a buffer solution and in an artificial viral transport medium widely used for the collection of nasopharyngeal swabs, and that no cross-reactivity is observed in the presence of different, non-target viral proteins. This SWCNT-SPE-based format of electrochemical aptasensor may be extended to the detection of other protein targets for which nucleic acid aptamer ligands are made available.

Here, we theoretically modeled the binding interaction of the Sars-CoV2 (Spike protein) utilizing molecular docking with some potential repurposed antiviral medications and two botanical products (Curcumin and Quercetin). Molecular docking between the drugs and the Sars-CoV2 proteins reflecting the pure electrostatic forces and H-bond formation is complemented with the DFT results that shed light on the electronic nature of the interactions. Moreover, DFT computations provide invaluable information about the drug reactivity indices calculated from the energies of the frontier orbitals. The DFT results indicate intermolecular electron donor-acceptor interaction besides the H-bond formation. Most of the considered medication molecules act as electron-sink candidates except EIDD-2801, the electron donor. The theoretical results show the high possibility of blocking the human cellular entry against Sare-Cov2 or weakening Sars-Cov2 activity due to the electronic donor-acceptor interactions. The findings are solely computational analysis and need to be corroborated by additional studies.

Background. The relationships between renin-angiotensin-aldosterone system (RAAS) and elevated parathyroid hormone levels in primary hyperparathyroidism (PHPT) is being actively discussed. But the way how parathyroid hormone interacts with renin and aldosterone currently is not clear.
Materials and methods. Forty patients aged 18 to 70 years with a confirmed diagnosis of PHPT were involved in the study. All patients were tested for the main parameters of phosphorus-calcium metabolism and the RAAS parameters (plasma renin, plasma aldosterone) before and 2 weeks after parathyroidectomy.
Results. Sixty percent of patients had any cardiovascular disease (CVD) and hypertension was the most common. Patients CVD in comparison with patients without CVD were older (61 and 41 years, respectively; p0.001), had a higher body mass index (28.9 and 21.9 kg/m2, respectively; p0.001) and had a lower aldosterone-to-renin ratio ARR (1.78 and 5.42, respectively; p=0.030). Patients with hypertension were older than patients with normal blood pressure (63 and 41 years, respectively; p0.001), had a higher body mass index (28.1 and 23.5 kg/m2, respectively; p=0.005), a lower ARR (1.46 and 5.82, respectively; p=0.001), as well higher levels of plasma renin (109.2 and 20.3 pg/ml, respectively; p=0.007) and serum total calcium (2.84 and 2.71 mmol/l, respectively; p=0.041). Correlation analysis showed that in patients with PHPT and CVD, the concentration of aldosterone is associated with the level of 24-hour urinary calcium (r=0.829, p=0.042), and in patients with symptomatic PHPT and CVD, the level of aldosterone correlated with the level of ionized calcium (r=-0.812, p=0.05). We found no significant differences between the levels of renin, aldosterone and ARR before and 2 weeks after parathyroidectomy. However, in the postoperative period, there were no differences in the levels of renin and ARR among patients with hypertension and without hypertension.
Conclusion. In our study we found that the levels of plasma renin and serum total calcium were higher in patients with PHPT and hypertension compared to patients with normal blood pressure. Also, we found the associations between plasma aldosterone and levels of ionized calcium and 24-hour urinary calcium. But the relationships between RAAS parameters and parameters of phosphorus-calcium metabolism need further investigations.
Intranasal corticosteroid use in patients with allergic rhinitis

Allergic rhinitis (AR) is one of the most common diseases in the world, which is based on IgE-mediated inflammation that develops after exposure to various allergens. About 40% of people suffer from the same or other allergic diseases, every third inhabitant of the Earth has symptoms of AR and every tenth has bronchial asthma. According to the ARIA classification, ARs are divided: by the nature of the flow, by the severity of the flow and by the stage of the flow; for symptoms, the proposed therapy, consisting of sequential steps. Groups of drugs include: systemic or topical blockers of histamine H1 receptors, intranasal and systemic corticosteroids, mast cell stabilizers (intranasal cromones), M-antagonists, antagonists of leukotriene receptors. Medicines do not give a lasting effect after their cancellation, therefore, with persistent AR, treatment should be prolonged; methods of application more often oral or intranasal. The advantages of the pharmacological antiallergic effect of InHCS are the simultaneous inhibition of both the early and late phases of the allergic response and the inhibition of all AR symptoms. The advantage of InHCS over oral administration is the minimal risk of developing systemic side effects against the background of the creation of adequate concentrations of the substance in the nasal mucosa, which allows to control the symptoms of AR. Based on data from a number of studies, the advantages of intrasal corticosteroids for AR, in particular fluticasone propionate, are used.

Several studies have recently been conducted showing persistent COVID-19 symptoms in patients recovering after the acute phase of the disease. Energy imbalance plays a leading role in the pathogenesis of post-COVID syndrome. The choice of a metabolic cytoprotection drug with anti-asthenic activity will be decisive for the further tactics of managing the patient not only in the hospital, but also during the entire further period of recovery after the infection.

Guided by the Bourdieu-Scheerens framework, this study uses transformative mixed methods exploratory sequential design to evaluate the “LET Intensive Review,” a university program for the Licensure Examination for Teachers (LET). The review program is regarded as an input, a means for achieving an output. While analysis includes the context, inputs, process, and outputs in education function, close attention is given to processes to elucidate contributing factors in the LET outcomes. Ethnography as the primary research design was used to explore pre-service teachers' (PSTs) experiences in the review, deploying the Bourdieusian framework in the analysis. In support of the qualitative findings, a descriptive research design was employed. The Mann-Whitney U Test and the Independent Samples t-test were performed to analyze the university passing percentage ratings in the LET elementary and secondary levels for first-timers before and during the conduct of the review. Integrative analysis of the qualitative and quantitative results followed to draw the mixed methods research findings. This evaluation reveals that the LET Intensive Review is effective, and the faculty agency and the administrator agency play a big part in the process. Most of the LET elementary level first-timers who took the review obtained significantly higher LET ratings than those from the previous batches who had not gone through the review. Financial constraints, weak basic education foundation, majorship, and low motivation affected the PSTs’ performance and education quality. The educational policy implications related to the urban-rural divide are also presented in this study.
