Abstract
PURPOSE Hypothyroidism is an endocrine disorder characterised by decreased T3, T4 and increased TSH levels. This study aims to examine the potential effects of Ferulic acid (FA) on rats with hypothyroidism induced by propylthiouracil through the estimation of biochemical parameters and histopathological studies. METHODS Twenty-five female wistar rats were allocated into five groups: Control group [1% CMC, p.o.], Disease group [PTU-50 mg/kg, p.o.], [Levothyroxine (LT4) group - 20 µg/kg, p.o. + PTU-50 mg/kg, p.o.], [FA -25 mg/kg, p.o. + PTU-50 mg/kg, p.o.] and [FA 50 mg/kg, p.o. + PTU-50 mg/kg, p.o.]. On 15th day blood was collected and serum was separated for estimation of biochemical parameters, liver and kidney homogenate was utilised for the estimation of oxidative stress markers and the thyroid gland was dissected to examine histological features. RESULTS PTU administration for 14 days showed a substantial decline in T3 and T4 and increases in TSH levels. PTU-administered rats significantly increased TC, TG and LDL levels, and decreased HDL levels. AST, ALT, urea, creatinine, and IL-6 were determined and these levels were significantly altered in PTU-induced hypothyroid group. In hypothyroid rats MDA, NO, GSH and SOD levels were significantly altered. However, treatment with FA for 14 days attenuated PTU-induced alterations. Furthermore, FA improves the histological changes of the thyroid gland. CONCLUSION In conclusion, FA treatment showed a protective effect against hypothyroidism by stimulating the thyroid hormones through the activation of thyroid peroxidase enzyme and improving thyroid function. In addition, FA diminished the increase in lipids, liver and kidney markers, oxidative stress and inflammation.

Abstract
Nonhealing diabetic wounds are often associated with significant mortality and cause economic and clinical burdens to the healthcare system. Herein, a biomimetic hydroscaffold is developed using omentum tissue-derived decellularized-extracellular matrix (dECM) and silk fibroin (SF) proteins that associate the behavior of a collagenous fibrous scaffold and a hydrogel to reproduce all aspects of the provisional skin tissue matrix. The chemical cross-linker-free in situ gelation property of the two types of SF proteins from Bombyx mori and Antheraea assamensis ensures the adherence of dECM with surrounding tissue on the wound bed, circumventing further suturing. The physicochemical and mechanical properties of the composite hydroscaffold (SF-dECM) were thoroughly evaluated. The hydroscaffolds were found to support the growth and proliferation of human dermal fibroblasts and influence the angiogenic potential of endothelial cells under in vitro conditions. Furthermore, the healing efficacy of the composites was evaluated by generating full-thickness wounds on a streptozotocin-induced diabetic rat model. The presence of dECM components in the composite facilitated the rate of wound closure, granulation tissue formation, and re-epithelialization by providing intrinsic cues to advance the inflammatory stage and stimulating angiogenesis. Collectively, as an off-the-shelf wound dressing requiring only a single topical administration, the SF-dECM hydroscaffold is a promising, cost-effective dressing for the management of chronic diabetic wounds.

Abstract
BACKGROUND Alzheimer's disease (AD) is an overwhelming neurodegenerative disease with progressive loss of memory. AD is characterized by the deposition of the senile plaques mainly composed of β-amyloid (Aβ) fragment, BDNF decline, Cholinergic system overactivity and neuroinflammation. Montelukast (MTK), a leukotriene receptor antagonist, showed astounding neuroprotective effects in a variety of neurodegenerative disorders. OBJECTIVE This study aims to investigate the ameliorative effects of Montelukast in the scopolamineinduced Alzheimer's disease (AD) model in rats and evaluate its activity against neuroinflammation. METHODS Thirty rats were split into five groups: Control group (1 mL/kg normal saline, i.p.), Montelukast perse (10 mg/kg, i.p.), Disease group treated with Scopolamine (3 mg/kg, i.p.), Donepezil group (3 mg/kg, i.p.), Montelukast treatment group (10 mg/kg, i.p.) and behavioural and biochemical tests were carried out to assess the neuro protective effect. RESULTS Scopolamine treatment led to a significant reduction in learning and memory and an elevation in cholinesterase levels when compared with the control group (p < 0.01). Additionally, elevated oxidative stress and Amyloid-β levels were associated with enhanced neuroinflammation (p < 0.05, p < 0.01). Furthermore, the decline in neurotrophic factor BDNF is also observed when compared with the normal control group (p < 0.01). Montelukast pre-treatment significantly attenuated learning and memory impairment and cholinesterase levels. Besides, Montelukast and standard drug donepezil administration significantly suppressed the oxidative stress markers (p < 0.01), Amyloid-β levels, neuroinflammatory mediators (p < 0.05) and caused a significant increase in BDNF levels (p < 0.05) Conclusion: Montelukast bestowed ameliorative effects in scopolamine-induced AD animal models as per the previous studies via attenuation of memory impairment, cholinesterase neurotransmission, oxidative stress, Amyloid-β levels, neuroinflammatory mediators and enhanced BDNF levels.

Abstract
Alzheimer's disease (AD) is one of the most prevalent and progressive neurodegenerative disorders, hallmarked by increased amyloid-β deposition and enhanced oxidative load in the brain, ensuing cognitive decline. The present study is aimed at elucidating the neuroprotective effect of saroglitazar, a dual peroxisome-proliferator-activated receptor (PPARα/γ) agonist used in the treatment of diabetic dyslipidemia, against memory impairment induced by intraperitoneal scopolamine injection. 30 male Wistar rats were randomly divided into the following five groups: (A) Veh + Veh, (B) SGZ + Veh, (C) Veh + SCOP, (D) DPZ + SCOP, and (E) SGZ + SCOP. Rats of the respective groups were pretreated with saroglitazar (10 mg/kg, p.o.) and donepezil (3 mg/kg, p.o.) once daily for 16 days. During the final 9 days of the study, a daily injection of scopolamine (3 mg/kg, i.p.) was administered to the respective groups. Adjacent to the scopolamine injection, behavioral tests such as the open field, Y maze, novel object recognition test, and Morris water maze were conducted to assess learning and memory. Additionally, biochemical parameters such as acetylcholinesterase (AChE), butyrylcholinesterase (BuChE), nitric oxide (NO), malondialdehyde (MDA), reduced glutathione (GSH), superoxide dismutase (SOD), brain-derived neurotrophic factor (BDNF), β-amyloid levels, and NF-κB were measured in the hippocampus. The rats that received scopolamine injections showed significantly impaired short-term spatial and learning memory. This was associated with an increase in β-amyloid, iNOS, nitric oxide (NO), malondialdehyde, NF-κB, and TNF-α levels in the hippocampus of AD rats. On the other hand, saroglitazar has provided promising data on its protective role in cognition by protecting the BDNF, SOD, and GSH decline. As a result, saroglitazar was found to be a promising therapy in AD by upregulating the antioxidant status and cholinergic activity and preventing memory loss. Collectively, findings in the present study revealed that saroglitazar protected AD by suppressing scopolamine-mediated learning and memory deficits, oxidative stress, and cholinergic damage. Studying these mechanisms may conclude the protective role of saroglitazar against AD. However, further studies in transgenic animals will provide numerous insights into treatment mechanisms and contribute to developing a therapeutic intervention for AD.

Abstract
Farnesol (FAR) is a sesquiterpene molecule with high lipophilicity that has antibacterial and other pharmacological properties along with broad nutritional values with high commercial values. Although having potential, FAR stability behavior and degradation kinetics are not available in the literature. Hence, it is very essential to develop a simple, rapid, accurate, precise, robust, cheap UHPLC-DAD method for FAR. It was also proposed to study mechanistic insights into FAR under different degradation conditions. Therefore, we hypothesized to do systematic stability studies along with degradation kinetic and accelerated stability studies. The developed method was validated. FAR was studied for stress studies, degradation kinetics and ADMET prediction of degradants. Degradation products were characterized using LC-QTOF-ESI-MS. Developed method consists of an isocratic mobile phase with a wavelength of 215 nm. The percent recoveries for FAR were observed within the acceptance limit of 98-102%. The eight major degradation products were formed during stress studies. FAR follows first-order degradation kinetics. FAR and all degradants were found to have more than 75% good human oral absorption, and are non-toxic. FAR UHPLC-DAD method was developed, validated and performed stability studies to know the possible degradation pattern along with degradation kinetic studies.

Abstract
The outbreak of COVID-19 was recognized in December 2019 in China and as of October5th, the pandemic was swept through 216 countries and infected around 34,824,108 individuals, thus posing an unprecedented threat to world's health and economy. Several researchers reported that, a significant mutation in membrane proteins and receptor binding sites of preceding severe acute respiratory syndrome coronavirus (SARS-CoV) to turned as novel SARS-CoV-2 virus and disease was named as COVID-19 (Coronavirus disease 2019). Unfortunately, there is no specific treatment available for COVID-19 patients. The lessons learned from the past management of SARS-CoV and other pandemics, have provided some insights to treat COVID-19. Currently, therapies like anti-viral treatment, immunomodulatory agents, plasma transfusion and supportive intervention etc., are using to treat the COVID-19. Few of these were proven to provide significant therapeutic benefits in treating the COVID-19, however no drug is approved by the regulatory agencies. As the fatality rate is high in patients with comorbid conditions, we have also enlightened the current in-line treatment therapies and specific treatment strategies in comorbid conditions to combat the emergence of COVID-19. In addition, pharmaceutical, biological companies and research institutions across the globe have begun to develop thesafe and effective vaccine for COVID-19. Globally around 170 teams of researchers are racing to develop the COVID-19 vaccine and here we have discussed about their current status of development. Furthermore, recent patents filed in association with COVID-19 was elaborated. This can help many individuals, researchers or health workers, in applying these principles for diagnosis/prevention/management/treatment of the current pandemic.

Abstract
The present study explored the antidepressant potential of vorinostat (VOR) against chronic social defeat stress (CSDS) in mice. Since this model has the remarkable capacity to delineate the resilient and the defeated mice, we also looked for their molecular deviations. Defeated mice showed classical phenotypic alterations such as anhedonia, social avoidance, anxiety and despair. Whereas, resilient mice were immune to the development of those. Both defeated and resilient mice demonstrated marked CORT elevation in blood. Development of resilience vs. defeat to CSDS was found to be associated with the differential nuclear levels of GR, HDAC3 and HDAC6 in the hippocampus. Activation of a stress responsive adaptive mechanism involving these mediators at the nuclear level might be offering resilience while maladaptive mechanisms leading to defeat. Interestingly, an elevated hippocampal HDAC6 level in defeated mice was also observed, which was restored by VOR treatment. Further studies will be necessary to delineate the HDAC6 associated antidepressant mechanisms. As HDAC3 and HDAC6 are crucial mediators of GR signaling, further molecular studies may aid in understanding the basis of development of resilience to target MDD with new prospective.

Abstract
Major depressive disorder (MDD) is estimated to impose maximum debilitating effects on the society by 2030, with its critical effects on health, functioning, quality of life and concomitant high levels of morbidity and mortality. Yet, the disease is inadequately understood, diagnosed and treated. Moreover, with the recent drastic rise in the pace of life, stress has materialized as one of the most potent environmental factors for depression. In this scenario, it is important to understand the modern pathogenetic hypotheses and mechanisms, and possibly try to shift from the traditional approaches in depression therapy. These include the elaboration of pathophysiological changes in heterogeneous systems such as genetic, epigenetic, serotonergic, noradrenergic, gamma-aminobutyric acid, glutamatergic and endocannabinoid systems, neurotrophic factors, HPA axis, immune system as well as cellular stress mechanisms. These components interact with each other in a complex matrix and further elucidation of their mechanism and cascade pathways are needed. This might aid in the identification of MDD subtypes as well as the development of sophisticated biomarkers. Further, characterization might also aid in developing multitargeted therapies that hold much promise as compared to the conventional monoamine based treatment. New candidate pharmacons, refined psychotherapeutic modalities, advanced neuro-surgical and imaging techniques as well as the implementation of pharmacokinetic, pharmacogenetic prescribing guidelines constitute the emerging expanses of MDD treatment.

Abstract
SARS-CoV-2, a newly emerged pathogen in December 2019, marked as one of the highly pathogenic Coronavirus, and altogether this is the third coronavirus attack that crossed the species barrier. As of 1st July 2020, it is spreading around 216 countries, areas or territories, and a total of 10,185,374 and 503,862 confirmed cases and death reports, respectively. The SARS-CoV-2 virus entered into the target cells by binding with the hACE2 receptors. Spike glycoprotein promotes the entry of the virus into host target cells. Literature reported a significant mutation in receptor binding sites and membrane proteins of the previous SARS-CoV to turned as SARS-CoV-2 virus, responsible for most dreadful pandemic COVID-19. These modifications may be the probable reason for the extreme transmission and pathogenicity of the virus. A hasty spread of COVID-19 throughout the world is highly threatening, but still, scientists do not have a proper therapeutic measure to fight with it. Scientists are endeavoring across the world to find effective therapy to combat COVID 19. Several drugs such as Remdesivir, Hydroxychloroquine, Chloroquine, Ribavirin, Ritonavir, Lopinavir, Favipiravir, Interferons, Bevacizumab, Azithromycin, etc. are currently under clinical trials. Vaccine development from various pharmaceutical companies and research institutes is under progress, and more than ten vaccine candidates are in the various phases of clinical trials. This review work highlighted the origin, emergence, structural features, pathogenesis, and clinical features of COVID-19. We have also discussed the in-line treatment strategies, preventive measures, and vaccines to combat the emergence of COVID-19.

Abstract
Chronic stress is the leading cause of memory impairment today. Various stress-based models are being developed for studying cognitive impairment. Repurposing of existing drugs in a new pharmacology class is the safest and cheapest option for treatment instead of new drug discovery. Vorinostat (VOR) is the first histone deacetylase (HDAC) inhibitor approved for the treatment of cutaneous T-cell lymphoma by the U.S. FDA. VOR follows the rule of five and is reported to cross the blood-brain barrier. Therefore, we aimed to evaluate the procognitive potential of VOR (25 mg/kg) administered by intraperitoneal (ip) route in a stress-based model of chronic corticosterone (CORT) injections (20 mg/kg, subcutaneously (sc)). The study comprised six groups. Normal mice were administered vehicle (VEH) (days 1-21, sc) in the first group, VOR (days 8-21, 25 mg/kg, ip) in the second group, and fluoxetine (FLX) (days 8-21, 15 mg/kg, oral) in the third group. Mice in the remaining three groups were given 20 mg/kg (sc) CORT for 21 days, and VOR (days 8-21, 25 mg/kg, ip) or FLX (days 8-21, 15 mg/kg, oral) was additionally administered to the treatment groups. Behavioral tests such as Morris water maze test, novel object recognition test, and object in place test were performed at the end of the dosing schedule to assess cognition. After behavior tests, mice were sacrificed, and hippocampus was separated from brain tissue for reverse transcriptase polymerase chain reaction (RT-PCR), Western blot, and immunohistochemistry studies. VOR treatment attenuated endoplasmic reticulum (ER) stress in CORT mice as evident from the reduction in DNA damage-inducible transcript 3 (Ddit3) (gene encoding CHOP), caspase 12 (Casp12), and calpain-2 (Capn2) mRNA levels, and cleaved caspase 3 (CASP3) protein expression. Bax inhibitor-1 (BI-1) was significantly increased in VOR-treated CORT mice. VOR also reversed CORT induced increase in HDAC2 level in the CA3 region. The protective effects of VOR were comparable to that of FLX in CORT mice. Thus, VOR has the potential to reverse cognitive dysfunction via modulation of ER stress markers and HDAC2.

Abstract
Full-thickness skin wounds, associated with deep burns or chronic wounds pose a major clinical problem. Herein, the development of in situ forming hydrogel using a natural silk fibroin (SF) biomaterial for treating burn wounds is reported. Blends of SF solutions isolated from Bombyx mori and Antheraea assama show inherent self-assembly between silk proteins and lead to irreversible gelation at body temperature. Investigation of the gelation mechanism reveals crosslinking due to formation of β-sheet structures as examined by X-ray diffraction and Fourier transform infrared spectroscopy. The SF hydrogel supports proliferation of primary human dermal fibroblasts and migration of keratinocytes comparable to collagen gel (Col) as examined under in vitro conditions. The SF hydrogel also provides an instructive and supportive matrix to the full-thickness third-degree burn wounds in vivo. A 3-week comparative study with Col indicates that SF hydrogel not only promotes wound healing but also shows transitions from inflammation to proliferation stage as observed through the expression of TNF-α and CD163 genes. Further, deposition and remodeling of collagen type I and III fibers suggests an enhanced overall tissue regeneration. Comparable results with Col demonstrate the SF hydrogel as an effective and inexpensive formulation toward a potential therapeutic approach for burn wound treatment.

Abstract
OBJECTIVE The main objective of the present study was to explore the antitumor activity of the ethyl acetate extract of the Alternanthera brasiliana (EAAB) and its antioxidant status against Ehrlich ascites carcinoma (EAC) in Swiss albino mice. MATERIALS AND METHODS Based on the preliminary in vitro cytotoxicity studies, EAAB was selected for anti-tumor and antioxidant effects. Anticancer activity of EAAB was evaluated against EAC in Swiss albino mice at the doses of 200 and 400 mg/kg. EAAB was administered for 14 consecutive days after induction of cancer. After 24 h of the last dose and 18 h of fasting, half of the mice were sacrificed and rest were kept alive for assessing any increase in life span. The antitumor effect of EAAB was assessed by evaluating tumor volume, viable and nonviable tumor cell count, tumor weight, hematological and biochemical parameters of EAC bearing host. Furthermore, the antioxidant and histopathological parameters were evaluated. RESULTS EAAB treatment has shown significant decrease in tumor volume, viable cell count, tumor weight and elevated the life span of EAC tumor bearing mice in a dose dependent manner. In hematological profile count of RBC, hemoglobin, and WBC were found reverted to normal. EAAB also significantly decreased the levels of lipid peroxidation and significantly increased the levels of GSH, SOD and Catalase. CONCLUSION From the above results it may be concluded that EAAB has potent dose dependent antitumor activity and is comparable to that of 5-flourouracil.

Abstract
Background: North East India is a rich source of medicinal plants and a number of plant extracts are used by tribal peoples living in this area for various disorders. L.aspera is such a plant, traditionally used as an antitumor agent. Aim: In the present study, aerial parts of L.aspera were investigated for antitumor activity in Dalton's lymphoma (DAL) bearing mice. The ability of plant extract in free radical scavenging, neoangiogenesis inhibition and macrophage stimulation were also checked. Materials and Methods: Based on the preliminary in vitro cytotoxicity studies ethyl acetate fraction of L.aspera (EALA) was selected for the detailed study. DAL ascites tumor model was performed to check the antitumor activity of EALA (200 and 400mg/kg of body weight). Hematological and histopathological parameters were estimated. Antioxidant levels, neoangiogenesis and peritoneal macrophage count were also determined. Results: In vitro MTT and Trypan blue assay results showed the cytotoxic effect of EALA in DAL cells lines. EALA treatment resulted in significant decrease in ascites tumor volume and viable cell count. Hematological and liver antioxidant parameters were normalised by EALA treatment. It was also found that EALA treatment inhibits neovascularisation and produce macrophage stimulation in treated mice. Conclusion: The results showed that EALA is a promising anticancer agent and its activity is comparable to the standard drug 5-Flouro uracil (5-FU).
