BackgroundColorectal cancer is still challenging for scientists and healthcare professionals. Conventional treatment methods are associated with various limitations at a clinical bed and patient’s compliance. Novel nanocarrier based approaches opened a new window for improved therapy and new future perspective.
IntroductionCancer is the deadliest disease globally and is challenging to healthcare systems. Colorectal cancer (CRC) is the third most common cancer in the world, affecting all age groups and the most common cancer in 23 countries, as per the World Health Organization (WHO).
MethodsIn this review, we addressed nanocarriers based strategic treatment of colorectal cancer, major findings, limitations, and future perspective. For this, we seriously reviewed literature downloaded from prime sources such as Google Scholar, Web of Science, PubMed, and Publon. To filter the exact need of data, we used keyword alone in combination. Various relevant articles were obtained from the reference section of the selected papers.
Results and DiscussionIt is necessary to have an effective and targeted treatment option to control CRC compared to available remedies. Nanotechnology has been widely used to diagnose and treat several cancer types. Advances in nanomedicine and phytonanomedicine promoted novel identification methods to treat colorectal cancer patients. There are several nanocarriers recommended for clinical purposes. However, to date, only a few clinically approved nanocarriers can load anticancer moieties and selectively bind to cancer cells. Some nanocarriers transport and release treatments to the target colorectal area but provide few benefits.
ConclusionIn this review, various nanoparticles (NPs) with unique properties have been discussed in relation to managing colorectal cancer, major outcomes of clinical trials, and successful patents published so far.

Evaluation of Wound Healing Activity of Statin Impregnated Collagen Scaffold in Wistar Albino Rats
Authors: Talasila Gopala Krishna Murthy and Bodepudi Sudheer ChowdaryBackgroundWound healing is a dynamic process that is affected by various processes. Medications involved in wound healing can interfere with clot formation, inflammation reduction, and cell proliferation. Collagen is the natural existing compound that has the ability to enhance tissue regeneration. Various drugs used for healing have cons like inhibiting DNA, RNA, or protein synthesis, resulting in decreased fibroplasias and neovascularisation of wounds.
ObjectiveThe objective of this work is the formulation of the collagen scaffold impregnated with the Atorvastain using cow urine as solvent.
MethodsThe methodology involves the isolation of the collagen from the bones of the animals by using acetic acid. The obtained collagen was subjected to homogenization and sonification to get a fine powder. To this solvent, Atorvastatin and glycerine were added then it was dried at 60°C for 24 hrs to get the impregnated scaffold. The formulated scaffold was evaluated for wound healing activity by using the excision wound model.
ResultsThe result shows that the scaffolds are good in nature and meet all the standards of the standard scaffold. The wound healing activity is assessed by using the excision wound healing model in rats. The results show the significant value of 99% wound healing activity from the statin-impregnated scaffold. The biological parameters like total collagen, hexosamine, and uronic acid were evaluated and these observations indicated higher values of 4.024 ± 0.069, 304 ± 4.11, and 75.83 ± 1.93 compared with the plain scaffold.
ConclusionThe optimised formulation exhibited good mechanical strength with better wound healing activity. The percent wound healing activity and antimicrobial activity observed from the collagen scaffold was found to be more significant compared with the scaffolds not containing statins.

A Parametric View of Hubble Parameter for Scalar Field Dark Energy Model
Authors: Sangita Goswami and Sudipta DasPurpose of the studyIn our present work, we have considered a simple parametric form of the Hubble parameter (H) for a canonical scalar field model described within a spatially flat FRW spacetime framework. Here we have considered a well-behaved parametrization scheme of the normalized Hubble parameter to explain the expansion history of the universe.
MethodsUnder this scenario, we have obtained the analytic solutions for various relevant cosmological parameters. We have also reconstructed the potential function V(φ) for the scalar field φ.
ResultsIt has been found that the deceleration parameter (q) shows exactly the nature which is well expected, i.e., an accelerated expansion for low z limit and deceleration for high z limit, which is essential for the structure formation of the Universe. Detailed data analysis has been carried out to check the viability of the proposed theoretical model by using combined dataset SNIa+H(z)+BAO/CMB and put constraints on the cosmological parameters, viz. the present value of the Hubble parameter H0.
ConclusionAs it has been observed that the deceleration parameter undergoes a smooth transition from an accelerating phase to decelerating expansion, this result supports the structure formation at the early time and the late time cosmic acceleration measurements. The results are found to be closer to the value obtained by the PLANCK collaboration.

Regulation of Genome-edited Technologies: Indian Policy Perspective
Authors: Amita Prasad and Murali Krishna ChimataThe rapid technological advances in the field of biotechnology have resulted in the formulation of effective and robust regulatory policy frameworks by different countries to ensure the safety of the products that are being developed through the application of genome editing techniques both in terms of environment and health safety perspectives. With over two and half decades of use of products derived from the application of genetic engineering technologies, this technology has stemmed the emergence of an even more advanced and precise targeted technology to address the most complicated and intrinsic challenges in a more precise manner which is now considered as Genome Editing. It is astounding to note that, at a time when several nations were debating and discussing the regulatory hurdles regarding the regulation of this technology, India has emerged as one nation with a clear policy framework with well-defined definitions in Rules 1989 itself, wherein, the definition of Gene Technology and Genetic Engineering clearly states that any alteration in the genome needs to be regulated and accordingly, India needs to regulate the products that would be developed through this novel genome editing technology. However, recognizing the global developments and after a thorough assessment of safety aspects, India, in the year 2022 promulgated the “ Guidelines for the Safety Assessment of Genome Edited Plants” wherein, it is explicitly detailed that products that are derived from SDN-1 and SDN-2 techniques and which are free of exogenous introduced DNA, are exempted from the provisions of Rules 7 to 11 (both inclusive) of the above said Rules 1989 and products derived from SDN-3 would be regulated as per provisions of Rules, 1989. If required, the concerned regulatory agencies may stipulate additional safety evaluation tests through better risk evaluation methodologies and a greater number of laboratories could also be set up along with empowering the human resource capacities for undertaking such state-of-the-art and precise techniques for the development of safe and beneficial products for the public without compromising on the safety.

This study also provides information about the views and awareness of the current generation towards ayurvedic knowledge, which in turn explains the decline of traditional healthcare practices.
Background:Ayurvedic medicine is one of the oldest and most traditional healthcare systems in India. There is limited documentation available regarding the information of traditional medicinal uses of plants even though various rural folks and elders have long been using plant-based formulations for curing human ailments. Hence, there is an urgent need to document this traditional knowledge to endorse the Ayurveda or Indigenous medicinal system before such valuable knowledge becomes inaccessible and extinct.
Objective:The present study was carried out to profile the current status of medicinal plants used by Traditional Vaidya’s/practitioners/locals, and discuss the status of Ayurveda and indigenous systems in the Northern states of India i.e., Haryana and Rajasthan.
Methods:To study currently available medicinal plants used by traditional Vaidyas in Northern states of India such as Haryana and Rajasthan, a survey among 50 Vaidyas of each state was undertaken. Information was gathered through interview and questionnaires consisting of 20 questions regarding their knowledge, expertise, targeted ailments, herbal formulations, and preservation techniques.
Results:According to the collected information, these Vaidyas have almost 4 to 40 yrs. of experience and acquired their knowledge in a variety of ways, including from academic institutions or their ancestors. By feeling the pulse in the wrist, these Vaidyas were able to diagnose ailments associated with the three doshas (Vata, Pitta, and Kapha) with medical precision via sensing the wrist's pulse. Different illnesses associated with kidney, lungs, digestive system, leukosis, diabetes, blood pressure etc. were treated by these traditional Vaidyas. In addition to prescribing medicines, Vaidyas carefully observe the patient's routine, physical health and their age group for better medication. Several indigenous medicinal herbs such as Ashwagandha, safed musli, gokhru, garmunda, bawli ghans, giloy, triphala, ginger, patthar chatta, Aloe vera, Stevia, and many other herbs are being used by these traditional Vaidyas for their herbal formulations.
Conclusion:This survey highlights Ayurveda and its use of plants in the field of medicine, through validation based on knowledge of traditional Vaidyas. This article also highlights the indigenous system and some important Indian medicinal plants of Haryana and Rajasthan and their therapeutic use in daily life. This survey enlightens the traditional Vaidyas and their knowledge of the Ayurveda medicinal system. This step might strengthen the validity of these products and provide a lead to target new formulation preparations. Many high-profile formulations could be prepared in the future, if most of these reputed traditional Vaidyas get organized.

Theoretical Investigation on the Mechanistic Pathways of Cp*Cobalt(III)-Catalyzed Transformation of N-Substituted Carbamoyl Indoles to Pyrroloindolone Derivatives
Authors: Rohini Saha, Saptarshi Saha and Gourab Kanti DasAimA theoretical study on the Cp*cobalt(III) catalyzed C-H functionalization transformation of N-substituted carbamoyl indoles with alkyne derivatives to pyrroloindoline derivatives has been performed using the DFT method.
BackgroundThe indole skeleton is important for developing regioselective C-H bond functionalisation reactions. Pyrrolo[1,2-a]indole bearing a 6-5-5 tricyclic skeleton (Scheme-1) is an important structural component found in many biologically active natural products and pharmaceuticals (such as antitumor mitomycin C, antimalarial flinderole B etc.).Thus C−H activation process has great demand methods for efficiently synthesizing a pyrrolo[1,2-a]indole unit from readily available starting materials. Matsunaga & Kanai et al. published one such attractive report, which shows pyrroloindoline derivatives can be synthesized (Scheme-2) through Cp*Co(III) catalysed C-H alkenylation and annulations from N-substituted carbamoyl indoles.
ObjectiveOur current project deals with determining the rate step of the reaction for the energetically favourable pathway and investigating the actual reason behind the regioselectivity of the products, whether it is steric or electronic effects of the substituents.
MethodsThe geometry optimization and energy calculations of all the systems were carried out with the Gaussian 09 software. Construction of trial geometries, monitoring of the progress of calculations and visualization of the final output was done by several graphical user interface software like Gauss View, Molden etc. Geometry optimization of all species is performed using M06-2X functional in DFT method as a method for performing optimization of structures. 6-31G (d, p) basis set was employed for all non-metal atoms, and the LANL2DZ basis set was employed for cobalt. The relaxed scan method was used to determine the geometries of several transition structures on the reaction pathway's potential energy surface (PES).
ResultsDFT study on a reaction of carbamoyl indoles with alkyne derivatives by activating Co(III)Cp* catalytic condition is done here. The targeting scheme followed the energetics of two possible pathways. The initial step of the reaction is the alkyne insertion step which needs 21.27 kcal mol-1 energy. In the first case, the final annulated product has been generated through a carbon-carbon bond formation, proton transfer and demetallation processes in path-a. The global activation barrier is quite high (30.17 kcal mol-1). However, the study of the second pathway, which generated the simple alkenylated product through the proto-demethylation process in path-b, reveals a more reliable activation barrier (21.27 kcal mol-1).
ConclusionA comparison of the energy requirement reveals that the formation of the final product should go through a favourable simple alkenylation process that is path-b for dimethyl amine. Due to the lower energy barrier, the simple alkenylation pathway (i.e., Path-b) is a more favourable one. The initial alkyne addition step is the rate-determining step. The regioselectivity of the alkyne addition is purely governed by the steric crowding around the substrate. Thus the favourable mode of alkyne addition has a lower energy barrier due to lesser steric interactions. This theoretical investigation may guide future researchers in developing another economical route for generating similar derivatives.
