The pandemic of viral diseases like novel coronavirus (2019‐nCoV) prompted the scientific world to examine antiviral bioactive compounds rather than nucleic acid analogous, protease inhibitors, or other toxic synthetic molecules. The emerging viral infections significantly associated with 2019‐nCoV have challenged humanity's survival. Further, there is a constant emergence of new resistant viral strains that demand novel antiviral agents with fewer side effects and cell toxicity. Despite significant progress made in immunization and regenerative medicine, numerous viruses still lack prophylactic vaccines and specific antiviral treatments that are so often influenced by the generation of viral escape mutants. Of importance, medicinal herbs offer a wide variety of therapeutic antiviral chemotypes that can inhibit viral replication by preventing viral adsorption, adhering to cell receptors, inhibiting virus penetration in the host cell, and competing for pathways of activation of intracellular signals. The present review will comprehensively summarize the promising antiviral activities of medicinal plants and their bioactive molecules. Furthermore, it will elucidate their mechanism of action and possible implications in the treatment/prevention of viral diseases even when their mechanism of action is not fully understood, which could serve as the base for the future development of novel or complementary antiviral treatments.

Diabetes mellitus (DM) is characterized by an absolute decline in insulin secretion and peripheral resistance and is the most prevalent metabolic and endocrine disorder. However, the pathogenesis of DM also includes adipocyte insulin resistance, increased glucagon secretion, increased renal glomerular glucose absorption, and neurotransmitter dysfunction. Although there is a wide spectrum of therapeutics available for glycemic control, owing to the identification of various pathogenic determinants of DM, management of DM remains challenging and complex. Current therapeutic interventions against DM focus mostly on glycemic control without considering the other pathological determinants that eventually lead to treatment failure and the progression of DM. Furthermore, long-term use of these conventionally available anti-diabetic drugs leads to various side effects, henceforth development of novel drugs against DM remains an unending search strategy for researchers. Various studies conducted in various parts of the world have proposed that these novel therapeutic interventions target multiple and alternate pathogenic hotspots involved in DM. The current review article discusses novel therapeutic options that hold particular promise to support their safety and discuss the side effects resulting from their use so that these novel candidate drugs can be effectively fabricated into potential drugs for the treatment of DM.

As per a recent study conducted by the WHO, 15.4% of all cancers are caused by infectious agents of various categories, and more than 10% of them are attributed to viruses. The emergence of COVID-19 has once again diverted the scientific community’s attention toward viral diseases. Some researchers have postulated that SARS-CoV-2 will add its name to the growing list of oncogenic viruses in the long run. However, owing to the complexities in carcinogenesis of viral origin, researchers across the world are struggling to identify the common thread that runs across different oncogenic viruses. Classical pathways of viral oncogenesis have identified oncogenic mediators in oncogenic viruses, but these mediators have been reported to act on diverse cellular and multiple omics pathways. In addition to viral mediators of carcinogenesis, researchers have identified various host factors responsible for viral carcinogenesis. Henceforth owing to viral and host complexities in viral carcinogenesis, a singular mechanistic pathway remains yet to be established; hence there is an urgent need to integrate concepts from system biology, cancer microenvironment, evolutionary perspective, and thermodynamics to understand the role of viruses as drivers of cancer. In the present manuscript, we provide a holistic view of the pathogenic pathways involved in viral oncogenesis with special emphasis on alteration in the tumor microenvironment, genomic alteration, biological entropy, evolutionary selection, and host determinants involved in the pathogenesis of viral tumor genesis. These concepts can provide important insight into viral cancers, which can have an important implication for developing novel, effective, and personalized therapeutic options for treating viral cancers.

Mosquito control is facing timely challenges due to the inadequate success of bio-control programs and emergence of resistance to the conventional synthetic insecticides, which have necessitated the need to investigate and develop unconventional strategies by means of eco-friendly, environmentally safe, and biodegradable products as mosquito larvicides⁷. Natural products from plants have been evaluated as prototypes for new insecticidal agents, as they comprise a rich source of bioactive compounds that are potentially suitable for utilization in integrated management programs⁸. Consequently, the present study was undertaken to investigate the larvicidal potential of root and leaf extracts of S. costus against the early 4^thinstar larvae of An. stephensi, Ae. aegypti, and Cx. quinquefasciatus, as possible control measures to prevent the incidence of vector-borne diseases. This is the first study of its kind, reporting the larvicidal activities of root and leaf extracts of S. costs against the tested mosquito vectors.

Regeneration is a rare occurrence in the animal kingdom, but the earthworm stands out as a remarkable example of this phenomenon. Recent research has highlighted the promising wound healing properties of extracts derived from earthworms. Therefore, we propose that earthworm granulation tissue extract (EGTE) may facilitate wound healing by regulating immune responses in a rabbit diabetic wound model. Electron microscopy reveals that 70 % EGTE possesses noteworthy porosity with spherical to irregularly oval configuration. Gas chromatography–mass spectrometry (GC–MS) Characterization of EGTE revealed higher levels of ergosta-5,7,22-trien-3-ol, (3. beta.,22E). In-Vitro studies revealed significant anti-oxidant, anti-inflammatory and anti-bacterial properties in dose dependent manner. Likewise, cytotoxicity assessments reveal that 70 % EGTE exhibits minimal harm to cells while displaying substantial antioxidant and anti-inflammatory activities. For In-Vivo studies excision wounds were created on the dorsal regions of the experimental animals and were divided as Group I (50 % EGTE), Group II (70 % EGTE), Group III (vehicle) and Group IV (distilled water). Over a 21-day observation period 70 % EGTE facilitated the early healing of wounds in the experimental animals, evident through prompt wound closure, granulation tissue formation, increased DNA content, enhanced tensile strength of the wound area and enhanced the expression/synthesis of wound healing markers/proteins. From these results it can be postulated that EGTE accelerates wound healing by immune modulation, dampening of inflammatory pathway and enhanced expression of growth markers. Henceforth making it promising candidate for therapeutic use in diabetic wound healing.
