    2-Deoxy-D-Glucose: A Novel Pharmacological Agent for Killing Hypoxic Tumor Cells, Oxygen Dependence-Lowering in Covid-19, and Other Pharmacological Activities
    (2023-03) Singh, R; Gupta, V; Kumar, A; Singh, K
    Te nonmetabolizable glucose analog 2-deoxy-D-glucose (2-DG) has shown promising pharmacological activities, including inhibition of cancerous cell growth and N-glycosylation. It has been used as a glycolysis inhibitor and as a potential energy restriction mimetic agent, inhibiting pathogen-associated molecular patterns. Radioisotope derivatives of 2-DG have applications as tracers. Recently, 2-DG has been used as an anti-COVID-19 drug to lower the need for supplemental oxygen. In the present review, various pharmaceutical properties of 2-DG are discussed.

    Abiotic stress tolerance and antifungal activities of rhizobacteria for the management of soil-borne pathogens
    (14-05) Poria, V; Jhilta, P; Kumar, S; Kumar, P
    Cotton production is negatively affected by both biotic (diseases and insects) and abiotic (high temperature, salinity, water deficit, and extreme pH) factors. Soil-borne diseases, especially wilts and rots, significantly reduce cotton yield. Thus, we aimed to isolate and identify multi-stress tolerant bacterial antagonistic agents (AGAs) against two major soil-borne pathogens, Macrophomina phaseolina and Fusarium oxysporum. A total of 132 isolates with distinct morphologies were recovered from 25 different rhizospheric soil samples of cotton. A dual culture plate and broth assay confirmed the antagonistic activity of the isolates against these phytopathogens. Four selected AGAs thrived in salt stress induced by different NaCl concentrations, up to 1.71 M, except for isolate 62, which survived up to 0.85 M. Under osmotic stress, all the AGAs were tolerant of up to − 1.03 MPa. Similarly, all the AGAs were able to survive over a temperature range of 20–50 ◦C except for isolate 62, which survived up to 45 ◦C and was regarded as thermotolerant. All four AGAs were able to grow at pH values ranging from 5 to 9. AGA 18 and S46-7 survived under highly acidic conditions (pH 4). These multi-stress tolerant AGAs also exhibited different plant growth-promoting activities, such as mineral solubilization, ACC-deaminase production, and IAA production. Molecular identification revealed the following AGAs: Bacillus siamensis SSVP1 (18), Bacillus halotolerans SSVP2 (34), Pseudomonas aeruginosa SSVP3 (62), and Bacillus tequilensis SSVP4 (S46-7). AGAs with multiple stress tolerance traits can serve as potential biocontrol agents in the field to reduce pesticide consumption in cotton-growing areas.

    Adaptogenic property of Asparagus racemosus: Future trends and prospects
    (2023-04) Singh, N; Garg, M; Prajapati, P; SIngh, P
    Major depressive disorder (MDD) is a multimodal neuropsychiatric and neurodegenerative illness characterized by anhedonia, continued melancholy, dysfunctional circadian rhythm and many other behavioral infirmities. Depression is also associated with somatic ailments such as car diometabolic diseases. The existing and upcoming hypotheses have succeeded in explaining the pathophysiology of depression. Only a few of the most validated theories, such as hyperactivity of the HPA axis, activated inflammatory-immune response, and monoaminergic and GABAergic deficit hypotheses, have been discussed in this review. So, an effective and safer alternative approach beyond symptomatic relief has been desired. Therefore, botanical products have steadily been probed to strengthen the modern medicinal system as a promising medicament. In this line, Asparagus racemosus Willd. belongs to Asparagaceace family is the well-documented adaptogen cited in the ancient texts namely, Ayurvedic, Greek, and Chinese medicine system. The whole plant possesses pleiotropic therapeutic activity, antioxidant, anti-inflammatory, immunomodulatory, neuroprotective, nootropic, antidepressant, etc., without showing any remarkable side effects. The literature review has also suggested that A. racemosus administration at varied levels alleviates depression by modulating the HPA axis, increasing BDNF levels, and monoaminergic and GABAergic neurotransmission. Alongside, spikes the level of antioxidant enzymes, SOD, GSH peroxidase, GSH, and catalase in distinct brain regions (i.e., hippocampus, prefrontal cortex, amygdala, and hypothalamus) and promote neurogenesis and neuroplasticity. Thus, it could be a new generation antidepressant that provides relief from both behavioral and somatic illness. The review first describes the plant characteristics, then discusses the hypotheses associated with the pathogenesis of depression, and gives an insight into A. racemosus antidepressant properties and the underlying mechanism.

    Advances in aggregation induced emission (AIE) materials in biosensing and imaging of bacteria
    (2021) Maruthi, M; Kalangi, S
    With their ubiquitous nature, bacteria have had a significant impact on human health and evolution. Though as commensals residing in/on our bodies several bacterial com munities support our health in many ways, bacteria remain one of the major causes of infectious diseases that plague the human world. Adding to this, emergence of antibi otic resistant strains limited the use of available antibiotics. The current available tech niques to prevent and control such infections remain insufficient. This has been proven during oneofgreatest pandemicofourgeneration,COVID-19.It hasbeenobservedthat bacterial coinfections were predominantly observed in COVID-19 patients, despite anti biotic treatment. Such higher rates of coinfections in critical patients even after antibi otic treatment is a matter of concern. Owing to many reasons across the world drug resistance in bacteria is posing a major problem i. According to Center for Disease control (CDC) antibiotic report threats (AR), 2019 more than 2.8 million antibiotic resis tant cases were reported, and more than 35,000 were dead among them in USA alone. In both normal and pandemic conditions, failure of identifying infectious agent has played a major role. This strongly prompts the need to improve upon the existing tech niques to not just effective identification of an unknown bacterium, but also to discrim inate normal Vs drug resistant strains. New techniques based on Aggregation Induced Emission (AIE) are not only simple and rapid but also have high accuracy to visualize infection and differentiate many strains of bacteria based on biomolecular variations which has been discussed in this chapter.

    Advances in Optical Visual Information Security: A Comprehensive Review
    (2024-01) Sachin; Kumar, R; Sakshi; Yadav, R; Reddy, S; Yadav, A; Singh, P
    In the modern era, the secure transmission and storage of information are among the utmost priorities. Optical security protocols have demonstrated significant advantages over digital counterparts, i.e., a high speed, a complex degree of freedom, physical parameters as keys (i.e., phase, wavelength, polarization, quantum properties of photons, multiplexing, etc.) and multi-dimension processing capabilities. This paper provides a comprehensive overview of optical cryptosystems developed over the years. We have also analyzed the trend in the growth of optical image encryption methods since their inception in 1995 based on the data collected from various literature libraries such as Google Scholar, IEEE Library and Science Direct Database. The security algorithms developed in the literature are focused on two major aspects, i.e., symmetric and asymmetric cryptosystems. A summary of state-of-the-art works is described based on these two aspects. Current challenges and future perspectives of the field are also discussed.

    Alpha logarithm transformed fréchetdistribution: Properties and estimation
    (Austrian Journal of Statistics, 2019) Dey, Sanku; Nassar, Mazen; Kumar, Devendra; Alaboud, Fahad
    In this paper, a new three-parameter distribution called the Alpha Logarithm Transformed Fr echet (ALTF) distribution is introduced which o ers a more exible distribution for modeling lifetime data. Various properties of the proposed distribu- tion, including explicit expressions for the quantiles, moments, incomplete moments, conditional moments, moment generating function R enyi and -entropies, stochastic ordering, stress-strength reliability and order statistics are derived. The new dis- tribution can have decreasing, reversed J-shaped and upside-down bathtub failure rate functions depending on its parameter values. The maximum likelihood method is used to estimate the distribution parameters. A simulation study is conducted to evaluate the performance of the maximum likelihood estimates. Finally, the pro- posed extended model is applied on real data sets and the results are given which illustrate the superior performance of the ALTF distribution compared to some other well-known distributions.

    Alpha power transformed inverse Lindley distribution: A distribution with an upside-down bathtub-shaped hazard function
    (2017-08) De, S; Nassar, M; Kumar, D
    The inverse Lindley distribution has been generalized by many authors in recent years. Here, we introduce a new generalization called alpha power transformed inverse Lindley (APTIL) distribution that provides better fits than the inverse Lindley distribution and some of its known generalizations. The new model includes the inverse Lindley distribution as a special case. Various properties of the proposed distribution, including explicit expres sions for the mode, moments, conditional moments, mean residual lifetime, Bonferroni and Lorenz curves, entropies, stochastic ordering, stress–strength reliability and order statistics are derived. The new distribution can have an upside-down bathtub failure rate function depending on its parameters. The model parameters are obtained by the method of maximum likelihood estimation. The approximate confidence intervals of the model parameters are also obtained. A simulation study is carried out to examine the performance of the maximum likelihood estimators of the parameters. Finally, two data sets have been analyzed to show how the proposed model works in practice.

    An Amended Crow Search Algorithm for Hybrid Active Power Filter Design
    (2023-08) Ali, S; Bhargava, A; Saxena, A
    Hybrid Active Power Filter (HAPF) imbibes the advantages of both passive and active power filters. These filters are considered one of the important technologies for mitigating harmonic pollution in electrical systems. Accurate estimation of filter parameters is a key component to reduce harmonic pollution effectively. In recent years, several optimization approaches have been reported to solve this estimation problem; still, this area is worthy of further investigation. This paper is a proposal for an estimator that can estimate the parameter of HAPF configuration accurately. For evolving this estimator, first, an objective function that mathematically embeds filter parameters and harmonic pollution is presented. For handling the optimization process, an Amended Crow Search Algorithm (ACSA) is proposed. ACSA employs a local search algorithm (in the form of a pattern search) for obtaining optimal results. The analysis of the estimation process is carried out on two HAPF configurations. Various analyses that include harmonic pollution statistical analysis along with fitness function value analysis reveal that the proposed algorithm acquires optimal results as compared with other recently published and reported algorithms. Further, the proposed filter configurations are tested with the existing filter. The results prove that the proposed filter shows promising results.

    Amla (Emblica officinalis) alleviates doxorubicin-induced cardiotoxicity and nephrotoxicity in rats
    (2024-11) Arora, M; Singh, M; Tomar, R; Singh, L; Jangra, A
    Introduction: Doxorubicin (DOX) is a widely used anticancer drug known for its significant cardiotoxic and nephrotoxic effects. Seeking remedies to mitigate these adverse effects is crucial. This study investigates the potential of Emblica officinalis (Amla) extract, a prominent component in Chinese and Indian traditional medicine systems, in alleviating DOX-induced cardiotoxicity and nephrotoxicity. Methods: DOX (20 mg/kg i.p., once) was given to rats to cause acute cardiotoxicity and nephrotoxicity. Rats received 16 similar and cumulative doses of DOX (1.25 mg/kg, i.p.) on alternate days for chronic cardiotoxicity and nephrotoxicity. Biochemical and histological evaluations were done to confirm the onset of cardiotoxicity and nephrotoxicity. Results: The cardioprotective and nephroprotective effects of Amla extract (AE) (150 mg/kg p.o. and 300 mg/kg p.o) were evaluated in comparison to Vitamin E (25 mg/kg p.o.). The treatment with AE (300 mg/kg/day, p.o.) considerably prevented DOX-induced cardiotoxicity, nephrotoxicity, and oxidative stress by positively altering the integrity of glomeruli, restoring the tissue GSH and decreasing serum TBARS. AE (300 mg/kg) was found to be more cardioprotective and nephroprotective than Vitamin E (25 mg/kg p.o.). Discussion: It may be concluded that the induction of cardiotoxicity and nephrotoxicity in rats may be due to DOX-induced oxidative stress, and chronic treatment with AE (300 mg/kg) is an effective way to alleviate the cardiotoxic and nephrotoxic adverse effects of DOX in rats. Moreover, given Amla’s historical and contemporary significance in Chinese and Indian traditional medicine systems, its potential therapeutic role merits further exploration in clinical settings.
