Abstract
Indian Jujube, also known as Ber or Ziziphus Mauritiana Lam., is a fruit-bearing tree endemic to South Asia, including India, Pakistan, Bangladesh, and Sri Lanka. The tree belongs to the buckthorn family and is known for its fruit, a tiny, round, or oblong-shaped drupe roughly the size of a cherry or a small plum. Indian Jujube has been growing for thousands of years. It is a popular fruit throughout the tropical and subtropical regions of Asia, Africa, and South America. Despite the fruit's delicious flavour and health benefits, it is also known for its therapeutic value. Many studies have suggested that various components of ber trees, such as fruit, seed leaves, roots, and flowers, include bioactive substances that demonstrate the potential for antioxidant activity and have anticancer, antibacterial, and antidiabetic effects. Due to the crop's minimal management requirements, it may slow down climate change and the threat of extreme soil and weather conditions, such as drought resistance, strong winds, erosion, high salt, and floods. The main objectives of the current systematic review are to understand Ber's chemical compositions, health benefits, culinary uses, major nutraceutical features, and its function in fostering livelihoods and climatic tolerance.

Abstract
Chemotherapeutic drugs are a known factor that impairs the system of life due to their severe side effects. A more worrying fact is that the patients administered with doxorubicin fall under the risk of cardiotoxicity. The evolution of exploring plant-derived compounds is a possible way to combat health issues in therapeutic applications. Hence, this study focuses on the protective effect of plant-based compound nuciferine (NFN) against doxorubicin-induced cardiotoxicity in both in vitro and in vivo models. In this investigation, nuciferine significantly reduces DOX-mediated cardiotoxicity by mitigating reactive oxygen species, thereby preventing DNA fragmentation, regulating apoptosis genes and reducing the caspase 3/7 levels in vitro. Besides, nuciferine has shown significant protection against DOX-induced cardiac impairment and the upregulation of cardiogenic markers in vivo. The DOX-induced oxidative stress can be mitigated via enhancing the endogenous antioxidants, thereby controlling ROS-mediated apoptosis. In virtue of these potential features, nuciferine can be a budding candidate to address therapeutic needs.

Abstract
The study explored the cardioprotective role of the methanolic leaf extract of Nelumbo nucifera and nuciferine against isoproterenol-induced myocardial infarction (MI) in Wistar rats. Pretreatment with leaf extract and nuciferine (200 and 20 mg/kg body weight, respectively) against MI induced by isoproterenol (85 mg/kg body weight) significantly decreased heart weight; levels of cardiac markers such as lactate dehydrogenase and creatine kinase-MB were similar to those in controls. The treatment significantly increased the content of endogenous antioxidants and decreased lipid peroxidation in all treated groups. Treated groups showed a significant reduction in heartbeats per minute as compared with the MI-induced positive control. The MI-induced group showed pathological implications such as tachycardia, left atrial enlargement, and anterolateral ST-elevated MI, which were absent in treated groups. Histology confirmed that the leaf extract and nuciferine prevented structural abnormality and inflammation in heart and liver tissues of treated groups. On in silico analysis, nuciferine showed stronger binding interaction with both β1 and β2 adrenergic receptors than isoproterenol. Hence, the leaf extract of N. nucifera and nuciferine could be used as plant-based cardioprotective agents.

Abstract
The extract of Caesalpinia pulcherrima (C. pulcherrima) is one of the common herbal drugs which have a key role in treating pyretic, microbial infections, cancer and for several other traditional systems of treatment. In our present work, we demonstrate the bioactivities of extracts and cytotoxicity of synthesized silver nanoparticles on HCT116 cell line. The qualitative phytochemical tests indicated the presence of some adequately required metabolites as follows; the total phenolic content in the aqueous extract contains a higher amount of phenolic compounds (815 ± 0.013 μgmg-1). The DPPH quenching activity of the aqueous extract showed an IC50 value of 18.7 μg which was equivalent to the IC50 value of ascorbic acid (15 μg) and methanolic extract (51 μg). The test extracts showed 4.6% haemolytic activity that attributes to its protective and non-toxic nature. The zone of inhibition of aqueous extract shown against the growth of E.coli was 25 mm. Further, silver nanoparticles synthesis was carried out with the extract and was characterized by X-ray diffraction, particle size analyzer, zeta potential, TEM- EDAX and UV spectroscopy. XRD analysis indicated the crystalline nature of silver nanoparticles with a face-centered cubic structure. The data obtained from the particle size analyzer demonstrated as 155.4 nm of the size of the synthesized silver nanoparticles. The values of zeta potential (-23.4 mV) revealed that the nanoparticles were extremely stable in colloidal form. SEM indicated the spherical shape of silver nanoparticles with the size range between 177.9 nm to 251.1 nm. Beside the efficient bioactivities, the synthesized C. pulcherrima silver nanoparticles showed significant cytotoxicity effect of 77.5% on a human colon cancer cell line. Therefore, along with antioxidant, antibacterial, haemolytic activity; C. pulcherrima also accomplished satisfactory cytotoxic property in anticancer mechanism as proven by this study.

Abstract
A multimillion-dollar boom is achieved every year by the ethnopharmaceutical companies, creating awareness around the globe to use herbal medicines to stay and live a healthy life. Nearly, two-thirds of the plants were discovered for herbal remedies, and some plants are even endangered to get extinct from the globe for their repeated utility. Sarcostemma brevistigma is one among the undiscovered medicinal plants which belongs to the family Asclepiadaceae found distributed in Indian states of Bihar, Bengal, Konkan, Tamil Nadu, and Kerala. This study was intended to determine the antidiabetic property of plant extract of Sarcostemma brevistigma evidenced by biochemical parameters, antioxidant activity, with the histopathological analysis in diabetic induced mice. Animals that were orally treated with the S. brevistigma extract showed blood glucose lowering effect when compared to the alloxan-induced mice, i.e., from 391.5 ± 6.3 to 193.6 ± 4.3 mg/dL. There is the significant increase in insulin level (P < 0.05) (27.97 ± 1.6 mIU/L) which is comparable to the metformin administered test group (30.35 ± 0.6 mIU/L). A significant difference (P < 0.05) of both ALT and AST levels were observed when compared to the other groups. A significant increase in antioxidant activity (reduced glutathione, malondialdehyde, superoxide dismutase) in plant extract administered group was observed when compared to the other treatment groups. Histopathological studies showed abnormalities in the liver, pancreas, kidney, lungs, heart, and spleen of alloxan-induced diabetic rats. The abnormalities were found to be normalized to a considerable extent after treatment with S. brevistigma extract. The results stood as evidence for S. brevistigma as an active antidiabetic herbal plant.

Abstract
The purpose of our work is to identify the bioactive compounds of bark and leaves extract from Ailanthus excelsa Roxb. and to explore its effectiveness against synthetic food dye. The presence of primary and secondary metabolites was confirmed by carrying out phytochemicals analysis. With the prior knowledge accessible on the indispensable secondary metabolites holding antioxidant and cytotoxicity activity, the quantitative screening of total phenolic and flavonoid content in methanolic and aqueous extract of bark and leaves from Ailanthus excelsa were done. Comparatively, a higher value of flavonoid (161±0.3μg/mg) and phenolic acid content (152.4±0.14μg/mg) was found in bark extract. By FTIR analysis, the characteristic peak was obtained at 1581.63 and 1598.99cm-1 confirmed the presence of functional groups associated to flavonoids and other phenolic groups respectively. In bark extract, 81% of DPPH inhibition was observed when compared to ascorbic acid (standard) 92% of free radical scavenging activity. Bark extract from Ailanthus excelsa exhibited 71% cytotoxicity against HeLa cell line (cervical cancer). In examining the toxicity level of crude extracts with red blood cells (RBC), the bark extract was showed a very less (2.8%) haemolytic activity. They also showed maximum zone of inhibition in antibacterial activity i.e. 13±0.5mm against Escherichia coli culture. At a concentration of 10mg/mL of crude extract from A. excelsa, 55% degradation of sunset yellow dye was observed. It concludes that, the compounds present in the A. excelsa, especially the bark extract showed better photocatalytic, haemolytic, antioxidant, cytotoxicity and antibacterial activity when compared to leaves extract.

Abstract
Ecofriendly synthesis of Palladium nanoparticles (PdNPs) were achieved using Phyllanthus emblica (P. emblica) seeds as reducing agent. Further the ecofriendly synthesized PdNPs were subjected for various analytical techniques like UV-Vis, FT-IR, XRD, Zeta potential, SEM and TEM. The results indicated that green synthesized PdNPs were spherical in shape with average particle size of 28±2nm with moderate stability. Further the synthesized PdNPs and extract were subjected for its antibacterial studies against various disease causing pathogens by agar well diffusion method. Seed extract resulted in 8.9±1.46mm against B. subtilis and PdNPs showed 9.6±1.10mm against S. aureus and synthesized PdNPs and extract were tested for hemolytic which resulted in 20% and 10% respectively. Toxicity studies were done against Artemia salina (A. salina). The LC50 value of green synthesized P. emblica capped PdNPs and the P. emblica seed extract were found to be less toxic for A. salina with a value of 1.00μg/mL and 1.25μg/mL. In addition samples were checked for in vitro cytotoxicity assays on HeLa cell lines.

Abstract
Background: Visual impairment tends to evoke more discomfiture than any other disability. Primarily, the biggest issue may be that blindness is visible. Furthermore, visual impairment develops serious medical, psychological, social and economic problems. Objectives: The focus of the current study was to investigate the psychological and psycho physiological problems of visually impaired adolescent students. Patients and Methods: Purposive sampling was adopted to select 150 visually impaired students (71 males and 72 females) from five schools in Coimbatore city of the Tamil Nadu state, India. Anxiety, frustration, aggression and social and personal adjustment levels of the visually impaired students were measured in this study using Taylor’s manifest anxiety scale, frustration test, aggression scale and the adolescent adjustment inventory, respectively. Results: Anxiety (χ2 = 185.66, P = 0 at P < 0.01), frustration (χ2 = 167.23, P = 0 at P < 0.01) and aggression (χ2 = 57.66, P = 0 at P < 0.01) were significantly related to adjustment among visually impaired students. The adjustment score had a significant positive correlation with anxiety (r = 0.919, P = 0 at P < 0.01), frustration (r = 0.887, P = 0 at P < 0.01) and aggression levels (r = 0.664, P = 0 at P < 0.01), anxiety was significantly correlated with frustration (r = 0. 961, P = 0 at P < 0.01) and aggression levels (r = 0.727, P < 0.01) and frustration was significantly correlated with aggression level (r = 0. 637, P = 0 at P < 0.01) of visually impaired adolescents. There was a positive relationship between psycho-physiological disorders and anxiety frustration, aggression and adjustment among visually impaired students. Conclusions: Visually impaired students exhibited significant levels of psychological and psycho-physiological problems.

Abstract
The objective of this study is to evaluate the chemical compounds present in the Malabar tamarind seed oil. The oil was extracted from the seeds of Malabar tamarind fruits collected from NBPGR Regional station, Thrissur. The seeds yielded 46.5 % of oil. Parameters such as the peroxide value, iodine value, saponification value, and acid value of the extracted Malabar tamarind seed oil were determined. These values were used to predict the quality of fatty acid methyl esters present in the oil. UV absorption spectroscopy of the oil showed hypsochromic shift, and the maximum absorbance was at 269 nm. The Fourier Transform Infrared Spectrum revealed the presence of olefin hydrogen and carbonyl group of ester compounds in the oil sample. The evaluation of the chemical compounds in the oil using gas chromatography coupled with mass spectrometry (GC-MS) revealed that, a total of five fatty acid methyl esters were present in the oil sample. Among the five fatty acid esters present in the Malabar tamarind seed oil, Methyl 16-methyl heptadecanoate (54.57 %) was found to be the predominant compound. This study also supports the presence of olefins in the long chain fatty acids from Nuclear Magnetic Resonance (NMR) data. There is a significant correlation between the properties and the characteristic profile of the oil sample. This study is the first report that shows Malabar tamarind as a promising source of oil seeds.

Abstract
We have developed an in silico model for simplified detection of five major food borne bacteria using common PCR primer based on conserved region flanking a variable region in the first rRNA operon sequences. The RFLP pattern exhibited on virtual SmaI and MboI digestion were unique to each genus. This design is based on the combination of comparative sequence analysis, conventional PCR and restriction digestion methods. We believe this approach as a better alternative to 16S rRNA sequencing based identification / detection of bacteria and suited for the resource limited academic research laboratories in which variety of bacteria are used in different students' projects.
