Human history has witnessed various pandemics throughout, and these cause disastrous effects on human health and country’s economy. Once again, after SARS (Severe Acute Respiratory Syndrome) and MERS (Middle East Respiratory Syndrome), the world is observing a very tough time fighting an invisible enemy, the novel COVID-19 coronavirus. Initially observed in the Wuhan province of China, now, it has spread across 210 countries. Number of corona affected confirmed cases have reached > 3 million globally and death toll has reached to 258,481 as on 6th May,2020. Researchers are working round the clock, forming collaborative efforts and sharing their data to come up with a cure for this disease. The new coronavirus genome was quickly sequenced and clinical and epidemiological data are continuously being collected and analyzed. This data is crucial for forming better public health policies and developing antiviral drugs and vaccines. As there is no vaccine available in market against COVID-19, personal health, immunity, social distancing and basic protection measures are extremely important. It is critical to avoid the virus infection and to strengthen the immune system as the coronavirus can be fatal for those with weak immunity.  This article reviews the nutritional and therapeutic potential of Spirulina, which is considered as superfood and a natural supplement to strengthen the immune system. Spirulina is highly nutritious and has hypolipidemic, hypoglycemic and antihypertensive properties. Spirulina contains several bioactive compounds, such as phenols, phycobiliproteins and sulphated polysaccharides and many more with proven antioxidant, anti-inflammatory and immunostimulant/ immunomodulatory effects.

An oleo gum resin guggulu is a product which obtained as a result of gummosis from the bark of Commiphora wightii (Arnott) Bhandari [syn. Commiphoramukul (Hook. Ex Stocks) Family, Burseraceae]. It has been known for its immense applicability in the Ayurveda since time immemorial for the treatment of variety of disorders such as inflammation, gout, rheumatism, impotence, leprosy, obesity, and disorders of lipids metabolism. It is a mixture of phytoconstituents like terpenoids, steroids, flavonoids, guggultetrols, lignans, sugars, and amino acids. This review is an effort to compile all the information available on all of its chemical constituents which are responsible for its therapeutic potential, limitation of guggul extracts and the necessity of novel principles for gum guggul. Nowadays, Guggul is available as the marketed formulation for curing numerous clinical conditions and is accessible in combination with various other ingredients. Though conventional dosage form shows the dominance as patient compliance and easy availability, yet it has found to pose the problems like dose fluctuation, peak-valley effect, non-adjustment of the administered drug, invasiveness etc. Guggul lacks its desired effect due to its low bioavailability and water solubility. This makes it a partial or a deficient therapy for remedy of many signs and symptoms. Novel drug delivery system (NDDS), a new approach and has excluded many of drawbacks exhibited by conventional dosage forms. Some of the novel dosage forms of guggul has been formed like nanoparticles, nanovesicles, gugglusomes and proniosomal gel. But still, the novel formulations for guggul has its less outspread in the market. Guggul can be executed as a profitable drug using NDDS. There is a need to highlight the unidentified and unexplained facts about guggul so as to make it more efficacious and effective in terms of bioavailability and aqueous insolubility.

: Cannabidiol (CBD) is a non-psychotropic phytocannabinoid which represents one of the constituents of the “phytocomplex” of Cannabis sativa. This natural compound is attracting growing interest since when CBD-based remedies and commercial products were marketed. This review aims to exhaustively address the extractive and analytical approaches that have been developed for the isolation and quantification of CBD. Recent updates on cutting-edge technologies were critically examined in terms of yield, sensitivity, flexibility and performances in general, and are reviewed alongside original representative results. As an add-on to currently available contributions in the literature, the evolution of the novel, efficient synthetic approaches for the preparation of CBD, a procedure which is appealing for the pharmaceutical industry, is also discussed. Moreover, with the increasing interest on the therapeutic potential of CBD and the limited understanding of the undergoing biochemical pathways, the reader will be updated about recent in silico studies on the molecular interactions of CBD towards several different targets attempting to fill this gap. Computational data retrieved from the literature have been integrated with novel in silico experiments, critically discussed to provide a comprehensive and updated overview on the undebatable potential of CBD and its therapeutic profile.

: Inflammatory bowel disease (IBD) is a chronic, elusive disorder resulting in relapsing inflammation of intestine with incompletely elucidated etiology, whose two representative forms are ulcerative colitis (UC) and Crohn’s disease (CD). Accumulating researches have revealed that the individual genetic susceptibility, environmental risk elements, intestinal microbial flora, as well as innate and adaptive immune system are implicated in the pathogenesis and development of IBD. Despite remarkable progression of IBD therapy has been achieved by chemical drugs and biological therapies such as aminosalicylates, corticosteroids, antibiotics, anti-tumor necrosis factor (TNF)-α, anti-integrin agents, etc., healing outcome still cannot be obtained, along with inevitable side effects. Consequently, a variety of researches have focused on exploring new therapies, and found that natural products (NPs) isolated from herbs or plants may serve as promising therapeutic agents for IBD through antiinflammatory, anti-oxidant, anti-fibrotic and anti-apoptotic effects, which implicates the modulation on nucleotide- binding domain (NOD) like receptor protein (NLRP) 3 inflammasome, gut microbiota, intestinal microvascular endothelial cells, intestinal epithelia, immune system, etc. In the present review, we will summarize the research development of IBD pathogenesis and current mainstream therapy, as well as the therapeutic potential and intrinsic mechanisms of NPs in IBD.

Novel Therapeutic Strategies

Background: Some of the current challenges and complications of cancer therapy are chemotherapy- induced peripheral neuropathy (CIPN) and the neuropathic pain that are associated with this condition. Many major chemotherapeutic agents can cause neurotoxicity, significantly modulate the immune system and are always accompanied by various adverse effects. Recent evidence suggests that cross-talk occurs between the nervous system and the immune system during treatment with chemotherapeutic agents; thus, an emerging concept is that neuroinflammation is one of the major mechanisms underlying CIPN, as demonstrated by the upregulation of chemokines. Chemokines were originally identified as regulators of peripheral immune cell trafficking, and chemokines are also expressed on neurons and glial cells in the central nervous system. Objective: In this review, we collected evidence demonstrating that chemokines are potential mediators and contributors to pain signalling in CIPN. The expression of chemokines and their receptors, such as CX3CL1/CX3CR1, CCL2/CCR2, CXCL1/CXCR2, CXCL12/CXCR4 and CCL3/CCR5, is altered in the pathological conditions of CIPN, and chemokine receptor antagonists attenuate neuropathic pain behaviour. Conclusion: By understanding the mechanisms of chemokine-mediated communication, we may reveal chemokine targets that can be used as novel therapeutic strategies for the treatment of CIPN.

If knowledge does not create a sustained and unified sense of organizational self (skepticism is rife) then strategic inquiry can turn to vision, a move advocated by Henry Mintzberg amongst others. The chapter considers what it is to author a strategic vision, using the novel The Shape of Things to Come by H. G. Wells as an indicative and provocative example of an organizational attempt to present its own form to itself and others. The risks associated with propaganda and dogmatic assertion are discussed, as are the strategy documents by which many modern organizations attempt to instil an equivalent vision to that envisaged by Wells.

Abstract Background Coronavirus disease 19 is a viral infection caused by a novel coronavirus, SARS-CoV-2. It was first notified in Wuhan, China, is now spread into numerous part of the world. Thus, the world needs urgent support and encouragement to develop a vaccine or antiviral treatments to combat the atrocious outbreak. Main body of the abstract The origin of this virus is yet unknown; however, rapid transmission from human-to-human “Anthroponosis” has widely confirmed. The world is witnessing a continuous hike in SARS-CoV-2 infection. In light of the outbreak of coronavirus disease 19, we have aimed to highlight the basic and vital information about the novel coronavirus. We provide an overview of SARS-CoV-2 transmission, timeline and its pathophysiological properties which would be an aid for the development of therapeutic molecules and antiviral drugs. Immune system plays a crucial role in virus infection in order to control but may have dark side when becomes uncontrollable. The host and SARS-CoV-2 interaction describe how the virus exploits host machinery and how overactive host immune response can cause disease severity also addressed in this review. Short conclusion Safe and effective vaccines may be the game-changing tools, but in the near future wearing mask, washing hands at regular intervals, avoiding crowed, maintaining physical distancing and hygienic surrounding, must be good practices to reduce and break the transmission chain. Still, research is ongoing not only on how vaccines protect against disease, but also against infection and transmission.

Abstract Since the spring of 2020 SARS-CoV-2, the novel coronavirus, has upended lives and caused a rethinking of nearly all social behaviors in the United States. This paper examines the ways in which the pandemic, shutdown, and gradual move towards “normal” have laid bare and obfuscated societal pressures regarding running out of time as it pertains to the residential university experience. Promised by movies, television, and older siblings and friends as a limited-time offer, the “typical” college experience is baked into the U.S. imaginary, reinforcing a host of notions of who “belongs” on campus along lines of race, class, and age. Fed a vision of what their whole lives “should be”, students who enter a residential four-year college are already imbued with a nostalgia for what is yet to come, hailed, in Althusser’s (2006[1977]) sense, as university subjects even before their first class. The upheaval of that subjecthood during the pandemic has raised important questions about the purpose of the college experience as well as how to belong to a place that is no longer there.

Vanishing Herds (2011) is Henry Ole Kulet’s novel that hovers around the ecological depletion caused by the anthropocentric attitude of the human beings. Set in the East African Savannah, the novel grapples with the critical issue of anthropogenic environmental degradation. The novel is based on the tribulations of a young Maasai couple –Kedoki and Norpisia whose epic journey through the wilderness provides a window through which the destruction of the physical environment can be viewed. Additionally, the text catalogues the challenges faced by a pastoralist community’s attempt to come to terms with the socio-economic realities of a fast-evolving contemporary society. The paper is an attempt to study this novel under the surveillance of green lens and throw light on the ecological destruction especially the clearing of the forest by human self centered endeavors and to critique the anthropocentric attitude of the human beings that render the environment at the verge of destruction.

Abstract This article analyzes queerness in Ocean Vuong’s On Earth We’re Briefly Gorgeous (2019), teasing out how the queer relationship at the core of the novel is framed. Ocean Vuong’s novel mobilizes queerness to straddle boundaries between cultures, gender roles and bodies. On Earth We’re Briefly Gorgeous places the queer sexual orientations and gender performances of its protagonists, one Vietnamese American, one white American, in firm relation to the formative force of cultural contexts. Zooming in on two young boys’ queerness, the novel diversifies gender roles and makes room especially for non-normative masculinities. What is more, On Earth We’re Briefly Gorgeous mobilizes the abject to showcase how queer sexual intimacy straddles boundaries between bodies and subjects. The article attends to language politics in connection with the novel’s coming-out performance, striated constructions of gender roles and their interplay with the abject and “bottomhood” (Nguyen 2014: 2) to come to grips with the novel’s diversification of queer masculinities.

Novel Virus

On 31st December 2019, China informed local WHO office of "cases of pneumonia of unknown etiology detected in Wuhan. As of 6th May 2020, there are nearly 3.6 million cases of corona virus infection and approximately 0.25 million deaths worldwide. The real-time data regarding the actual number of cases, as it originates from the epicenter is the key to the estimation of the case fatality rate, hospitalization rates, expected timeline of arrival of contagion, and other epidemiological data. The novel virus has no available literature pertaining to its epidemiological parameters, on which experts can base their estimates and hence the challenge in planning for epidemic management. Bolstering this challenge are the reports alleging under-reporting by Chinese authorities. Alleged toned down numbers could have led to erroneously low estimates contributing to inadequate public health response globally. We conducted a simulation on epidemiological model of COVID-19 to find out expected time off arrival of infections and mortality in different countries and compared this to actual data.
