Abstract
Recent efforts have focused on developing improved drug delivery systems with enhanced therapeutic efficacy and minimal side effects. Micelles, self-assembled from amphiphilic block copolymers in aqueous solutions, have gained considerable attention for drug delivery. However, there is a need to further enhance their efficiency. These micelles offer benefits like biodegradability, biocompatibility, sustained drug release, and improved patient compliance. Yet, researchers must address stability issues and reduce toxicity. Nanoscale self-assembled structures have shown promise as efficient drug carriers, offering an alternative to conventional methods. Fine-tuning at the monomeric and molecular levels, along with structural modifications, is crucial for optimal drug release profiles. Various strategies, such as entrapping hydrophobic drugs and using polyethylene oxide diblock copolymer micelles to resist protein adsorption and cellular adhesion, protect the hydrophobic core from degradation. The polyethylene oxide corona also provides stealth properties, prolonging blood circulation for extended drug administration. Amphiphilic copolymers are attractive for drug delivery due to their adjustable properties, allowing control over micelle size and morphology. Emerging tools promise complex and multifunctional platforms. This article summarizes about the challenges as far as the use of micelles is concerned, including optimizing performance, rigorous pre-clinical and clinical research, and suggests further improvement for drug delivery efficacy.

Abstract
Globally, people are in great threat due to the highly spreading of viral infectious diseases. Every year like 100-300 million cases of infections are found, and among them, above 80% are not recognized and irrelevant. Dengue virus (DENV) is an arbovirus infection that currently infects people most frequently. DENV encompasses four viral serotypes, and they each express comparable sign. From a mild febrile sickness to a potentially fatal dengue hemorrhagic fever, dengue can induce a variety of symptoms. Presently, the globe is being challenged by the untimely identification of dengue infection. Therefore, this review summarizes advances in the detection of dengue from conventional methods (nucleic acid-based, polymerase chain reaction-based, and serological approaches) to novel biosensors. This work illustrates an extensive study of the current designs and fabrication approaches involved in the formation of electrochemical biosensors for untimely identifications of dengue. Additionally, in electrochemical sensing of DENV, we skimmed through significances of biorecognition molecules like lectins, nucleic acid, and antibodies. The introduction of emerging techniques such as the CRISPR/Cas' system and their integration with biosensing platforms has also been summarized. Furthermore, the review revealed the importance of electrochemical approach compared with traditional diagnostic methods.

Abstract
BACKGROUND The liver is a well-known player in the metabolism and removal of drugs. Drug metabolizing enzymes in the liver detoxify drugs and xenobiotics, ultimately leading to the acquisition of homeostasis. However, liver toxicity and cell damage are not only related to the nature and dosage of a particular drug but are also influenced by other factors such as aging, immune status, environmental contaminants, microbial metabolites, gender, obesity, and expression of individual genes Furthermore, factors such as drugs, alcohol, and environmental contaminants could induce oxidative stress, thereby impairing the regenerative potential of the liver and causing several diseases. Persons suffering from other ailments and those with comorbidities are found to be more prone to drug-induced toxicities. Moreover, drug composition and drug-drug interactions could further aggravate the risk of drug-induced hepatotoxicity. A plethora of mechanisms are responsible for initiating liver cell damage and further aggravating liver cell injury, followed by impairment of homeostasis, ultimately leading to the generation of reactive oxygen species, immune-suppression, and oxidative stress. OBJECTIVE To summarize the potential of phytochemicals and natural bioactive compounds to treat hepatotoxicity and other liver diseases. STUDY DESIGN A deductive qualitative content analysis approach was employed to assess the overall outcomes of the research and review articles pertaining to hepatoprotection induced by natural drugs, along with analysis of the interventions. METHODS An extensive literature search of bibliographic databases, including Web of Science, PUBMED, SCOPUS, GOOGLE SCHOLAR, etc., was carried out to understand the role of hepatoprotective effects of natural drugs. RESULTS Bioactive natural products, including curcumin, resveratrol, etc., have been seen as neutralizing agents against the side effects induced by the drugs. Moreover, these natural products are dietary and are readily available; thus, could be supplemented along with drugs to reduce toxicity to cells. Probiotics, prebiotics, and synbiotics have shown promise of improving overall liver functioning, and these should be evaluated more extensively for their hepatoprotective potential. Therefore, selecting an appropriate natural product or a bioactive compound that is free of toxicity and offers a reliable solution for drug-induced liver toxicity is quintessential. CONCLUSIONS The current review highlights the role of natural bioactive products in neutralizing drug-induced hepatotoxicity. Efforts have been made to delineate the possible underlying mechanism associated with the neutralization process.

Abstract
Pectinases are a collection of multiple enzymes that have a common substrate, that is, pectin. They can act on different parts of pectin due to the structural heterogeneity of pectin. Therefore, they have been placed in different groups, such as protopectinases, polygalacturonases, polymethylesterases, pectin lyases, and pectate lyases. They are naturally present both in multicellular organisms such as higher plants and in unicellular organisms such as microbes. In past decade, it has been witnessed that chemical and mechanical methods employed in industrial processes have led to environmental hazards and serious health disorders, thus increasing the search for eco-friendly approaches with minimal health risks. Hence, microbial enzymes have been extensively used as safer alternative for these environmentally unsafe methods. Among these microbial enzymes, pectinases hold great significance and is one of the principal enzymes that have been used commercially. It is predominantly used as a green biocatalyst for fruit, fiber, oil, textile, beverage, pulp, and paper industry. Thus, this review focuses on the structure of pectin, microbial sources of pectin, and principle industrial applications of pectinases.

Abstract
BACKGROUND As per the guidelines of the Indian Council of Medical Research, nasopharyngeal and oropharyngeal swabs in viral transport medium (VTM) are to be stored at 4 °C for less than 5 days and for more than 5 days at -70 °C. Samples are not transported or stored as per prescribed conditions because of the limitations, resulting in an apprehensive diagnosis. The aim of the study was to test the stability of the SARS-CoV-2 sample stored in VTM at different temperatures. METHODS In this study, the stability of 21 positive and 9 negative samples for SARS-CoV-2 was evaluated in commercial VTM at different temperatures (-80 °C, -20 °C, 4 °C, and 25 to 30 °C). Stability was checked for up to 50 days in the above storage conditions at different intervals. PathoDetect™ and Hi-PCR® kits were used for the detection of the four genes of SARS-CoV-2. The Cycle Threshold (Ct) value for determining the positivity of samples for PathoDetect™ was < 40 and for Hi-PCR® was < 38. RESULTS The SARS-CoV-2 confirmatory genes (RdRp and E genes) and the internal housekeeping gene remained detectable even on the 50th day of the study. The Ct of the RdRp and E genes were found to increase with storage duration, but all positive samples remained positive till the end of the study, or the Ct value remained below the cut-off level. The negative samples gave consistent results until the end of the study. When the differences in Ct values were compared between the days in a set of experiments, they were not significantly different except in a few samples. CONCLUSION The SARS-CoV-2 genetic materials in commercial VTM were stable at room temperature to -80 °C for 50 days.

Abstract
Endo 1,4-β-d-xylanases (EC3.2.1.8) are one of the key lignocellulose hydrolyzing enzymes. Xylan, which is present in copious amounts on earth, forms the primary substrate of endo-xylanases, which can unchain the constituent monosaccharides linked via β-1,4-glycosidic bonds from the xylan backbone. Researchers have shown keen interest in the xylanases belonging to glycoside hydrolase families 10 and 11, whereas those placed in other glycoside hydrolase families are yet to be investigated. Various microbes such as bacteria and fungi harbor these enzymes for the metabolism of their lignocellulose fibers. These microbes can be used as miniature biofactories of xylanase enzymes for a plethora of environmentally benign applications in pulp and paper industry, biofuel production, and for improving the quality of food in bread baking and fruit juice industry. This review highlights the potential of microbes in production of xylanase for industrial biotechnology.

Abstract
Condensed and hydrolyzable tannins are secondary metabolites present in almost every plant part. Tannase enzyme acts on hydrolyzable tannins to produce gallic acid and tannase-mediated end-products with immense therapeutic potential. Seven different fruits with significant presence of hydrolyzable tannin content were selected to check for phenol, tannin, and hydrolyzable tannin contents. Prunus domestica had the maximum phenol content, that is, 85.4 ± 0.207, followed by Syzygium cumini, Fragaria ananassa, Rubus fruticosus, and Psidium guajava. Plum showed the maximum number of hydrolyzable tannins. Fruit extracts were subjected to tannase hydrolysis and their antimicrobial and antioxidant activities were determined. There was a significant increase in the antioxidant abilities of the fruits with Punica granatum extract, displaying the highest decline of 132 units of IC50 followed by F. ananassa hydrolyzable extract, showing a decrease from 224.75 to 119.98 μg/mL. The extracts also depicted a significant increase in antibacterial activity after hydrolysis against Escherichia coli, Pseudomonas aeruginosa, Bacillus subtilis, and Staphylococcus aureus with Rubus idaeus aqueous extract observed to be most effective against E. coli. The increase in antioxidant and antibacterial activity can be attributed to the production of tannase-mediated products formed after the biotransformation of hydrolyzable tannins present in the aqueous extracts.

Abstract
Cow's milk, urine, dung, ghee, and curd (together known as "Panchgavya") have incomparable medicinal value in Ayurveda and ancient Indian clinical methods. Panchgavya is also known as Cowpathy in Ayurveda. In India, the cow is revered as a goddess known as "Gaumata" because of its nurturing qualities similar to those of a mother. Almost no adverse effects are associated with using Panchgavya, which is why it is recommended in Ayurveda for treating disorders affecting numerous body systems. Its possible antimicrobial effects have piqued the curiosity of medical researchers and practitioners. Cow milk is widely regarded as a nutritious diet and has been shown to effectively treat various medical conditions, including high body temperature, pain, cancer, diabetes, kidney diseases, and weakness. Milk can prevent the growth of microorganisms, has erotic qualities when combined with the leaves of medicinal herbs, and the fat in milk has anticancer characteristics. Toned and skim milk, lassi, yoghurt, cottage cheese, and khoa all come from milk and have important medicinal characteristics. Curd (dahi) is recommended as a blood purifier for conditions such as hemorrhoids, piles, and gastrointestinal issues. Ghee made from cows has been shown to boost immunity. It is important to highlight the use of cow dung as an antifungal and for treating malaria and tuberculosis. It has the potential to aid in the development of a populace free from disease, the creation of sustainable energy systems, the fulfilment of all nutritional needs, the elimination of poverty, the promotion of organic farming culture, and the like. Cow urine is a powerful remedy for numerous medical conditions, including but not limited to epileptic convulsions, diabetes, hepatitis, inflammation, fever, and anaemia. The current review article explores how the Panchgavya ingredients can be employed to safeguard human and animal health.

Abstract
Tannins are secondary metabolites that belong to the family of polyphenolic compounds and have gained a huge interest among researchers due to their versatile therapeutic potential. After lignin, these are the second most abundant polyphenols found in almost every plant part like stem, bark, fruit, seed, leaves, etc. Depending upon their structural composition, these polyphenols can be divided into two distinct groups, namely condensed tannins and hydrolysable tannins. Hydrolysable tannins can be further divided into two types: gallotannins and ellagitannins. Gallotannins are formed by the esterification of D-glucose hydroxyl groups with gallic acid. The gallolyl moieties are bound by a depside bond. The current review focuses mainly on the anti-carcinogenic potential of recently discovered gallotannins, ginnalin A, and hamamelitannin (HAM). Both of these gallotannins possess two galloyl moieties linked to a core monosaccharide having anti-oxidant, anti-inflammatory, and anti-carcinogenic abilities. Ginnalin A is found in plants of the genus Acer whereas HAM is present in witch hazel plants. The biosynthetic pathway of ginnalin A along with the mechanism of the anti-cancer therapeutic potential of ginnalin A and HAM has been discussed. This review will certainly help researchers to work further on the chemo-therapeutic abilities of these two unique gallotannins.

Abstract
Abstract
Butyric acid is an important chemical which has many applications in the chemical, food, and pharmaceutical industries. Butyraldehyde, which is derived from propylene, is now converted into butyrate by petrochemical processes known as oxo synthesis. Because of its poor productivity and low butyrate concentration in the fermentation broth, biotechnological production of butyric acid is not economically viable. Typically, a sizable amount of the overall production expenses goes toward the cost of the fermentation substrate. If the fermentation process can use minimal biomass as the feedstock, a cost-competitive production of butyric acid from the fermentation technique would be generated with a strong market prospect. Organic wastes are recommended as a source of butyric acid fermentation feedstock because they are inexpensive, can be generated in huge numbers, and are biodegradable. With a focus on the low-cost feedstock, the many uses of butyric acid are discussed, with its present production status. As a result, this paper explores several butyric acid fermentation-related problems and offers ideas for potential solutions.

Introduction
Despite the recent advancements in the management of Complete Heart Block (CHB), the aetiology of CHB is still idiopathic in most of the cases. Our study explores this hitherto untouched aspect of complete heart block.
Purpose
We aimed to assess the aetiological profile of Complete Heart Block patients in our study.
Methods
The study population consisted of 60 patients with complete heart block aged between 30 to 80 years, attending as an inpatient in ER. Oxidative stress was measured by serum MDA, serum GSH, serum Catalase activity and serum SOD activity. Antioxidant activity was obtained by measuring the levels of serum total antioxidant capacity. Inflammatory stress was measured by IL-5 and TNF-alpha levels. These values were compared to 30 healthy controls with no prior history of smoking and diabetes mellitus.
Results
The mean age of the patient was 62.48 ± 7.98 years and the gender distribution was 37 males and 23 females out of 60 patients. The mean value of serum MDA (ng/mL) in cases is 1451.26 ± 206.32, and in controls, the mean value is 1197.98 ± 234.71 (p=<0.001). The mean value of serum GSH (mcg/mL) in cases is 46.982 ± 18.613, and in controls, the mean value is 54.155 ± 10.762 (p=0.027). The mean value of serum Catalase Activity (U/min/mg protein) in cases is 10.763 ± 4.038 and in controls, the mean value is 19.878 ± 7.787 (p=0.003). The mean value of serum SOD Activity (U/g) in cases is 24.950 ± 5.4565, and in controls, the mean value is 46.214 ± 14.6309 (p=0.891). The mean value of serum Total Antioxidant Capacity (U/mL) in cases is 5.546 ± 0.620 and in controls, the mean value is 8.346 ± 2.781 (p=0.025). The mean value of serum IL-5 (pg/mL) in cases is 481.442 ± 28.8995, and in controls, the mean value is 67.347 ± 20.445 (p<0.001). The mean value of serum TNF-ALFA (pg/mL) in cases is 196.741 ± 73.771, and in controls, the mean value is 144.530 ± 42.599 (p= 0.081).
Conclusions
During a complete heart block, SOD (p=0.891), CAT (p=0.003), GSH (p=0.027) and total antioxidant (TAOC) (p=0.025) were significantly decreased in cases, compared to healthy controls, thus suggesting that the elevated levels of oxidative free radicals causes endothelial dysfunctioning. The increase in ROS was observed by a highly significant increase of malondialdehyde (MDA) (p=<0.001) showing high ROS-mediated tissue damage. Besides damage by oxidative stress, our study suggests that there are certain inflammatory markers like TNF-α and IL-5 that actively participate in causing heart block. There was a significant increase in the concentration of IL-5 (p<0.001) in the cases as compared to the controls.

Background
Morphological features of neointimal tissue play a pivotal role in the pathophysiology of In-Stent Restenosis (ISR) after percutaneous coronary intervention, hence understanding these features and patterns is crucial.
Purpose
The present study was designed to qualitatively and quantitatively assess neointimal characteristics of lesions using OCT in patients presenting with ISR.
Methods
This was a single-center, prospective, observational study performed between 1st August 2020 and 30th December 2021 at a tertiary-care center in India. Patients diagnosed with stable angina and acute coronary syndrome with post-procedural angiographically documented restenosis (>50%) were included. Qualitative and quantitative assessment of neointimal hyperplasia patterns was performed using OCT.
Results
A total of 34 patients with ISR were studied. Neointimal hyperplasia was classified as (i) homogenous group (n=18) and (ii) non-homogenous group (n=16). As many as 14 (77.8%) diabetics belonged to the homogenous group. Predominant plaque characteristics such as neoatherosclerosis, cholesterol crystals, and calcium were documented in 14 (77.8%), 12 (66.7%), and 11 (61.1%) patients in the homogenous group and in 10 (62.5%), 10 (62.5%), and 9 (56.2%) patients in the non-homogenous group, respectively. Unexpanded stent struts were identified in 11 (61.1%) and 11 (68.8%) patients in the homogenous and non-homogenous groups, respectively. Mean strut thickness was 93.73 ± 31.03 µm and 83.54 ± 18.0 µm, ISR was 72.50 ± 15.93% and 65.37 ± 21.69%, the neointimal thickness was 588.06 ± 167.82 mm and 666.25 ± 218.05 mm, and neointimal hyperplasia was 54.54 ± 11.23% and 59.26 ± 8.86% in the homogenous and non-homogenous groups, respectively.
Conclusion
Neoatherosclerosis and stent underexpansion was predominantly observed in our study, which was in contrast to most of the existing literature [1,2,3], and only diabetes was found to be significantly associated with homogenous neointimal hyperplasia, irrespective of the generation of the stent.

Abstract
Colorectal cancer is the second leading cause of cancer deaths worldwide and has engrossed researchers' attention toward its detection and prevention at early stages. Primarily associated with genetic and environmental risk factors, the disease has also shown its emergence due to dysbiosis in microbiota. The microbiota not only plays a role in modulating the metabolisms of metastatic tissue but also has a keen role in cancer therapy. The immune cells are responsible for secreting various chemokines and cytokines, and activating pattern recognition receptors by different microbes can lead to the trail by which these cells regulate cancer. Furthermore, mixed immune reactions involving NK cells, tumor-associated macrophages, and lymphocytes have shown their connection with the microbial counterpart of the disease. The microbes like Bacteroides fragilis, Fusobacterium nucleatum, and Enterococcus faecalis and their metabolites have engendered inflammatory reactions in the tumor microenvironment. Hence the interplay between immune cells and various microbes is utilized to study the changing metastasis stage. Targeting either immune cells or microbiota could not serve as a key to tackling this deadly disorder. However, harnessing their complementation towards the disease can be a powerful weapon for developing therapy and diagnostic/prognostic markers. In this review, we have discussed various immune reactions and microbiome interplay in CRC, intending to evaluate the effectiveness of chemotherapy and immunotherapy and their parallel relationship.

Abstract
Vulture declines in South Asia were caused by accidental poisoning by the veterinary non-steroidal anti-inflammatory drug (NSAID) diclofenac. Although veterinary use of diclofenac has been banned, other vulture-toxic NSAIDs are legally available, including aceclofenac, which has been shown to metabolise into diclofenac in domestic cattle. We gave nine domestic water buffalo the recommended dose of aceclofenac (2 mg kg-1 body weight), collected blood at intervals up to 48 h, and carried out a pharmacokinetic analysis of aceclofenac and its metabolite diclofenac in plasma. Aceclofenac was rapidly converted to diclofenac, and was barely detectable in plasma at any sampling time. Diclofenac was present within 20 min, and peaked 4-8 h after dosing. Aceclofenac is a prodrug of diclofenac, and behaves similarly in domestic water buffalo as it did in domestic cattle, posing the same risk to vultures. We recommend an immediate ban on the veterinary use of aceclofenac across vulture-range countries.

Abstract
Background Meningiomas are the most prevalent of all intracranial tumours. Although they are mostly benign, about 20% of meningiomas are atypical or malignant. Knowledge of their histologic grade can be clinically useful while planning surgery. Objectives To differentiate between various grades and subtypes of meningiomas with advanced MR parameters. Method We assessed the advanced MR imaging characteristics of 27 histopathologically confirmed meningiomas on a 3T MRI, of which 23 were grade I meningiomas (2 fibroblastic, 9 meningothelial, 9 transitional, 3 unspecified) and 4 were grade II/III meningiomas (2 atypical, 1 papillary, 1 anaplastic). Analysis of the ADC, FA, λ1, λ2, λ3 and mean diffusivity was performed using standard post-processing software. Results The mean size of atypical meningiomas (5.9 cm ± 0.7 cm) was significantly higher (p = 0.038, 95% confidence interval [CI]) than that of typical meningiomas (4.6 cm ± 1.6 cm) with a cut-off value of 6.05 cm (75% sensitivity and 87% specificity). The mean cerebral blood flow (CBF) (ASL) of atypical meningiomas (286.70 ± 8.06) was significantly higher (p = 0.0000141, 95% CI) than that of typical meningiomas (161.09 ± 87.04) with a cut-off value of 276.75 (66.7% sensitivity and 75% specificity). Among the typical meningiomas, transitional subtypes had the lowest ADC. High FA and planar coefficient (CP) values and low λ3 and spherical coefficient (CS) values were seen in fibroblastic meningiomas. Fibroblastic meningiomas also showed the lowest vascularity among typical meningiomas. Conclusion Tumour size and ASL perfusion are two parameters that could differentiate between typical and atypical meningiomas while ADC, FA, λ3, CP, CS, rCBF and rCBV may be helpful in distinguishing different subtypes of typical meningiomas.

A search of bibliographic databases was carried out with a focused question on microRNA-Disease Prediction. A deductive qualitative content analysis approach was further employed to assess the research's overall outcomes, review articles on prediction tools in miRNA-Diseases, and analyse the interventions.
Results:
Diagnosis and therapeutics of diseases and miRNA prediction methods hold importance in identifying the regulatory mechanisms. Collections of efficient miRNA prediction methods to identify miRNA-mRNA-disease regulatory relationships have been presented through this review, consolidating the potential of miRNAs as a diagnostic and prognostic biomarker of multiple diseases, including COVID-19.
Conclusions:
The role of miRNA in the aetiology and pathogenesis of wide-range of pathologies, including viral, bacterial to chronic diseases such as cancer, is quite feasible through the modern tools in bioinformatics which has been elaborated focusing upon miRNA-disease prediction methods and their application potential establishing miRNAs as a robust and reliable biomarker in clinico-medical studies.

Abstract
Discharge of untreated or partially treated toxic dyes containing wastewater from textile industries into water streams is hazardous for environment. The use of heavy metal(s) rich dyes, which are chemically active in azo and sulfur content(s) has been tremendously increasing in last two decades. Conventional physical and chemical treatment processes help to eliminate the dyes from textile wastewater but generates the secondary pollutants which create an additional environmental problem. Microalgae especially the diatoms are promising candidate for dye remediation from textile wastewater. Nanoporous diatoms frustules doped with nanocomposites increase the wastewater remediation efficiency due to their adsorption properties. On the other hand, microalgae with photosynthetic microbial fuel cell have shown significant results in being efficient, cost effective and suitable for large scale phycoremediation. This integrated system has also capability to enhance lipid and carotenoids biosynthesis in microalgae while simultaneously generating the bioelectricity. The present review highlights the textile industry wastewater treatment by live and dead diatoms as well as microalgae such as Chlorella, Scenedesmus, Desmodesmus sp. etc. This review engrosses applicability of diatoms and microalgae as an alternative way of conventional dye removal techniques with techno-economic aspects.

Abstract
Tuberculosis (TB) is a serious zoonotic threat, impacting the human-livestock-wildlife interface globally. Here, we evaluated the status and histomorphological differentiation of TB lesions in 89 morbid cases of wild animals (bovids, cervids, carnivores, non-human primates, and pachyderms) in India. Histomorphological and molecular studies were done using Ziehl-Neelsen (ZN) staining, immunohistochemistry, and polymerase chain reaction (PCR), whereas cultural isolation was performed on selected samples. A total of 32 (35.95%) cases were confirmed as TB, comprising of 12 carnivores, 09 bovids, 06 cervids, 04 non-human primates, and a pachyderm. The TB lesions in the lungs, liver, and lymph nodes varied from the large-sized caseous nodules filled with dry cheesy material in bovids and cervids to variable-sized cavitations containing liquefied caseum in carnivores' lungs. The lungs, livers, and spleens of non-human primates exhibited small to medium-sized nodules. Histologically, lesions were divided into four categories (Types I, II, III, and IV) based on the extent of necrosis, the presence of mineralization, giant cells, and fibrous encapsulation. Extensive caseous necrosis with calcification, abundant giant cells, and thick fibroblastic encapsulation were consistent findings in the lungs, livers, and lymph nodes of bovids and cervids, whereas airway impaction with cellular exudate containing a teeming number of acid-fast bacilli and, at times, alveolar rupture leading to cavity formation was present in the lungs of carnivores. Absence of calcification and fibrous encapsulation was recorded in lungs of non-human primates. Immunohistochemical labelling with anti-early secretory antigenic target-6 (ESAT-6) and culture filtrate protein-10 (CFP-10) antibodies showed mild, moderate, and intense positive reactions in type II and III, type I, and type IV granulomatous lesions, respectively. Molecular detection by PCR revealed Mycobacterium tuberculosis (12 carnivores, 02 non-human primates and 01 pachyderm), M. bovis (02 cervids and 01 bovid) and M. orygis (02 cervids and 01 bovid). Cultural isolation confirmed M. tuberculosis in 03 carnivores and M. orygis in 02 cervids and 01 bovid. Our findings imply that TB is quite prevalent in the wildlife of India and there are considerable differences in the histomorphological lesions induced by distinct Mycobacterium species in different wild animals. The circulation of TB organisms in wild animals warrants a strict surveillance programme to identify the carrier status of these animals so that effective TB control strategies can be formulated to prevent spillover and spillback incidences at the human-livestock-wildlife interface.

Abstract
Microorganisms are stupendous source of secondary metabolites, having significant pharmaceutical and industrial importance. Genome mining has led to the detection of several cryptic metabolic pathways in the natural producer of secondary metabolites (SMs) such as actinobacteria and fungi. Production of these bioactive compounds in considerable amount is, however, somewhat challenging. This led to the search of using epigenetics as a key mechanism to alter the expression of genes that encode the SMs toward higher production in microorganisms. Epigenetics is defined as any heritable change without involving the changes in the underlying DNA sequences. Epigenetic modifications include chromatin remodeling by histone posttranslational modifications, DNA methylation, and RNA interference. Biosynthetic gene cluster for SMs remains in heterochromatin state in which the transcription of constitutive gene is regulated by epigenetic modification. Therefore, small-molecule epigenetic modifiers, which promote changes in the structure of chromatin, could control the expression of silent genes and may be rationally employed for discovery of novel bioactive compounds. This review article focuses on the types of epigenetic modifications and their impact on gene expression for enhancement of SM production in microorganisms.

Abstract
BACKGROUND To determine patient and surgical factors associated with the use of 360-degree laser retinopexy during primary pars plana vitrectomy (PPV) ± scleral buckle (SB) for rhegmatogenous retinal detachment (RRD) and its impact on surgical outcomes. METHODS Patients who underwent PPV ± SB for repair of non-complex RRD at a single centre were included in this retrospective study. The primary outcome was single surgery anatomical success (SSAS). Secondary outcomes included visual acuity, epiretinal membrane formation, the presence of cystoid macular oedema, tonic pupil and corneal epithelial defects. Multiple logistic regression and multivariate regression was used. RESULTS The study included 192 cases, of which 130 received 360-degree laser. Worse preoperative logMAR visual acuity (P = 0.009), male sex (P = 0.060), higher PVR grades, supplemental SB (P = 0.0468) and silicone oil/C3F8 tamponade (P < 0.0001) were associated with 360-degree laser use. No significant associations between 360-degree laser and SSAS (P = 0.079), final logMAR visual acuity (P = 0.0623), ERM development (P = 0.8208), postoperative CMO (P = 0.5946), tonic pupil (P > 0.9999) or corneal epithelial defects (P = N/A) were found. CONCLUSIONS 360-degree laser retinopexy during primary PPV ± SB for RRD was associated with more complex cases and more extensive operations. Even when accounting for this, there was no difference in surgical outcomes or complication rates.

Abstract
Population declines of Gyps vultures across the Indian subcontinent were caused by unintentional poisoning by the non-steroidal anti-inflammatory drug (NSAID) diclofenac. Subsequently, a number of other NSAIDs have been identified as toxic to vultures, while one, meloxicam, is safe at concentrations likely to be encountered by vultures in the wild. Other vulture-safe drugs need to be identified to reduce the use of those toxic to vultures. We report on safety-testing experiments on the NSAID tolfenamic acid on captive vultures of three Gyps species, all of which are susceptible to diclofenac poisoning. Firstly, we estimated the maximum level of exposure (MLE) of wild vultures and gave this dose to 40 Near Threatened Himalayan Griffons G. himalayensis by oral gavage, with 15 control birds dosed with benzyl alcohol (the carrier solution for tolfenamic acid). Two birds given tolfenamic acid died with elevated uric acid levels and severe visceral gout, while the remainder showed no adverse clinical or biochemical signs. Secondly, four G. himalayensis were fed tissues from water buffaloes which had been treated with double the recommended veterinary dose of tolfenamic acid prior to death and compared to two birds fed uncontaminated tissue; none suffered any clinical effects. Finally, two captive Critically Endangered vultures, one G. bengalensis and one G. indicus, were given the MLE dose by gavage and compared to two control birds; again, none suffered any clinical effects. The death of two G. himalayensis may have been an anomaly due to i) the high dose level used and ii) the high ambient temperatures at the time of the experiment. Tolfenamic acid is likely to be safe to Gyps vultures at concentrations encountered by wild birds and could therefore be promoted as a safe alternative to toxic NSAIDs. It is manufactured in the region, and is increasingly being used to treat livestock.

Abstract
Funding Acknowledgements
Type of funding sources: None.
Background
Optical coherence tomography (OCT) with its superior resolution has several benefits over coronary angiography (CA) to guide percutaneous coronary intervention (PCI). Despite the benefits of OCT in comparison with angiography, it is not widely used in developing countries like India data is limited in India specifically in all comer population to meet unmet need.
Objective
Here we aim to determine the clinical efficacy and safety outcomes of OCT versus CA alone in guiding PCI in all-comer patients.
Methods
This was a retrospective study which included 434 all comer patients which were propensity matched. These patients underwent PCI at our center between December 2018 and June 2020. The primary endpoint was MACE, a composite of cardiovascular death, repeat revascularization, stent thrombosis, recurrent ischemia and target vessel myocardial infarction (TV-MI) at 6 months. Secondary endpoint was target lesion failure (TLF), composite of stent thrombosis and in-stent restenosis. Safety endpoints were post-PCI s. creatinine and hospital stay and other outcome includes post PCI rise in CK-MB.
Results
A total of 217 patients were included in each group: the OCT group and conventional angiography guided PCI (angio group) after propensity matching. Compared to angio group, patients presenting with unstable angina, NSTEMI were significantly higher in the OCT group (55.7% vs 43.3%, p = 0.0095; 17.5% vs 10%, p = 0.02, respectively) while patients with STEMI were significantly low in the OCT (23.5% vs 41.5%, p = 0.00005). Number of balloons, maximum balloon size and left main interventions and contrast volume were more in OCT group than angio group (4.21 ± 1.67 vs 3.86 ± 1.76, P= 0.0034; 3.77 ± 0.63 mm vs 3.51 ± 0.52 mm,P < 0.0001; 24.52% vs 13.36 %,P = 0.003 and 202.53 ± 73.15 ml vs 161.91 ± 69.23 ml, P< 0.0001 respectively). The incidence of MACE at 6 months was numerically lower in the OCT group vs angio group but the difference was not statistically significant (15 [6.9%] vs 21 [9.7%]; p = 0.2964). No cases of TV-MI, TLF (stent thrombosis or in-stent restenosis) is observed in both the groups. Post procedure rise in CKMB was more in Angio group in comparison to OCT group (6.16 ± 31.28 ng/ml vs 39.5 ± 108.71 ng/ml, p < 0.001). Optimal stent expansion (>80%) was seen in 71.5% patients in post OCT-guided PCI. In OCT guided PCI group, OCT identified stent underexpansion in 28.5%, stent malapposition in 3.7%, stent edge dissection in 4.1%, and tissue prolapse in 10% of the patients.
Conclusion
In this large retrospective study, OCT guided PCI is feasible and OCT-guided PCI has tendency to improve clinical outcomes at six months follow up compared to conventional angiography guided PCI in all comer patients.

Abstract
In the processes of molecular docking and simulation studies; the computational techniques have a vast and significant role in drug discovery process. The rigid view in the binding of both target and ligand is the basis of modeling strategy process. More evolution to such processes with the time has lead in revealing the path of understanding the dynamic nature of binding processes. In this chapter we have focused on molecular docking along with dynamic studies in reference to biological processes.

Abstract
Only three cases of pleomorphic adenomas (PAs) of ectopic lacrimal gland mass in deep orbital location have been reported in the literature. This report describes a case of PA of the ectopic lacrimal gland situated deep in the orbit leading to proptosis, which was managed successfully by supraorbital orbitotomy via eyebrow incision. A 60-year-old female presented with complaints of gradually progressive, painless proptosis of the right eye. Imaging revealed a well-defined circumscribed mass lesion in the right orbit located predominantly in the postero-superior aspect of the globe. The patient underwent complete excision through supraorbital orbitotomy approach, using eyebrow incision. There was no clinical evidence of recurrence at eight months follow up. In orbit, PAs of the ectopic lacrimal gland are extremely rare, and the success of the treatment depends on the removal of the tumor with its capsule.

Abstract
Introduction: Burn injury is a highly devastating injury accounting for the major cause of disability-adjusted life years (DALYs) lost mostly in developing countries. Physical trauma, body disfigurement, the social stigma associated with injury completely shatter an individual’s life. Aim: To study the quality of life among burn injury patients. Methodology: A cross-sectional hospital-based descriptive study was done on 150 burn injury patients. During the initial recruitment from Burns and Plastic Surgery Ward, socio-demographic profile and burn incident-related data were collected, whereas the WHO QoL-BREF tool was applied after 3 months of discharge during a follow-up visit in the outpatient department of Burns and Plastic Surgery to assess the quality of life among subjects. Data were compiled in MS Excel and statistical analysis was done using SPSS 20 version. Results: The study revealed poor quality of life among four domains of QoL; it was most inferior in the psychological domain followed by the physical health domain, environment domain, and social relationship domain. Conclusion: Advancement in the medical field has improved the survival rate in victims although the patients recover from the acute painful phase of physical trauma. However, the psychological and social impacts of injury remain unaddressed leading to a poor QoL. There is a need for an integrated approach for prevention and enhancement of the quality of care for the victims in all four domains of life. More emphasis is needed on rehabilitative care for long-term improvement in the QoL of the affected person.

Abstract
INTRODUCTION Despite causing one of the most dreaded diseases of small ruminants, relatively little is known about the pathogenic events, antigen distribution and the cells responsible for the uptake and transmission of peste-des-petits-ruminants virus (PPRV) during primitive stages of infection. OBJECTIVES We aimed at deciphering the sequential tissue tropism, pathological events and putative role of M2c macrophages during incubatory, prodromal and invasive stages of PPRV infection. METHODOLOGY A total of 10 goats were sequentially sacrificed at 1, 2, 3, 4, and 5 days post-infection (dpi, n = 2 per time-point) following intranasal inoculation with a highly virulent strain of PPRV (lineage IV PPRV/Izatnagar/94). Histological evaluation to assess PPRV mediated pathologies, RT-qPCR and immunohistochemistry (IHC) to decipher sequential virus distribution, and dual immunolabelling to determine the role of M2c macrophage in early PPRV uptake and transmission was performed. RESULTS PPRV/Izatnagar/94 caused major pathologies in the lung tissues. Unprecedentedly, PPRV nucleic acid and antigens were detected in various tissues as early as one dpi. RT-qPCR revealed PPRV in the nasal cavity, trachea, bronchi, tongue and lymph nodes draining these tissues from 1 dpi. IHC affirms cells residing in the lamina propria and submucosa of the respiratory tract and tongue and peribronchiolar areas of lungs as the primary target of PPRV. Following initial replication in the respiratory tract, PPRV is transmitted to the regional lymph nodes where primary viral amplification occurs. After viraemia and secondary replication in generalized lymphoid tissues, PPRV infects and replicates in the epithelial cells. Further, we localized CD163+ M2c macrophages in the goat tissues, but dual IHC elucidated that M2c macrophages do not facilitate uptake and transmission of PPRV during the early stages of infection. CONCLUSION Our study substantiates the disease establishment process and pathogenesis of PPRV/Izatnagar/94 during the incubatory and prodromal stages of infection. Further, we have also observed M2c macrophage distribution in the goat tissues and demonstrated that they do not pick and transmit PPRV.

Abstract
Phytochemicals are the natural biomolecules produced by plants via primary or secondary metabolism, which have been known to have many potential health benefits to human beings. Flavonoids or phytoestrogens constitute a major group of such phytochemicals widely available in variety of vegetables, fruits, herbs, tea, and so forth, implicated in a variety of bio-pharmacological and biochemical activities against diseases including bacterial, viral, cancer, inflammatory, and autoimmune disorders. More recently, these natural biomolecules have been shown to have effective antiviral properties via therapeutically active ingredients within them, acting at different stages of infection. Current review emphasizes upon the role of these flavonoids in physiological functions, prevention and treatment of viral diseases. More so the review focuses specifically upon the antiviral effects exhibited by these natural biomolecules against RNA viruses including coronaviruses. Furthermore, the article would certainly provide a lead to the scientific community for the effective therapeutic antiviral use of flavonoids using potential cost-effective tools for improvement of the pharmacokinetics, bioavailability, and biodistribution of such compounds for the concrete action along with the promotion of human health.

Abstract
Our study aimed to develop and find out the best drug candidate against the mechanistic target of rapamycin (mTOR/FRB) domain having a critical role in the aetiology of breast cancer. The FKBP12-rapamycin-binding (FRB) domain in the essential phosphoinositide 3 kinase/mammalian target of rapamycin (PI3K/AKT/mTOR) pathway has been a vital player in the disease progression in breast cancer. By using structure-based drug designing , the best possible targets have been identified and developed. The three-dimensional structure of the target protein was generated using I-TASSER. The ligands were generated against the most suitable target active site using standard tools for active site identification. Furthermore, the seed molecule was drawn using Chemsketch, which was then grown into the pocket using Ligbuilder. The obtained ligands were further validated using online programs for bioavailability and toxicity, followed by molecular dynamic simulations. The study concludes that the equilibrated NVT-NPT complexes indicate LIG2 stability over LIG3. RMSD and RMSF have shown that the complex of LIG2 is more stable than LIG3. LIG2 has the potential antagonistic properties to target the mTOR/FRB domain and has therapeutic implications for breast cancer.

Abstract
The study reports the multi-drug resistant (MDR), extended spectrum beta-lactamase (ESBL) producing and carbapenem resistant Escherichia coli (CRE) isolated from rescued sloth bear (Melursus ursinus), India. Non-duplicate faecal samples from 21 adult rescued sloth bears were collected at once during 2015-2016 and processed for isolation of E. coli and antibacterial susceptibility pattern. From 21 samples, 45 E. coli were isolated and on phenotypic screening, 23 were MDR, 17 were ESBL producers, and five were carbapenem-resistant (CR). Three E. coli isolates (6.67%, 3/45) showed no resistance, however 42 isolates (93.33%, 42/45) exhibited resistant to at least one antibiotics. The MDR isolates carried beta-lactamase, chloramphenicol, aminoglycosides, tetracycline, fluroquinolone, and sulphadimidine resistance genes. All the phenotypic ESBL producing isolates harbored blaCTX-M genes. On genotypic screening, three CRE (60.0%, 3/5) were positive for blaNDM carbapenemase gene and efflux pump-mediated carbapenem resistance was detected in two CRE isolates (40.0%, 2/5) which were negative for carbapenemase genes. The CRE isolates (n = 5) also co-harbored AMR genes like blaTEM-1, blaAmpC, qnrA, qnrB, qnrS, tetA, tetB and sulI. Virulence screening of the resistant isolates detected the presence of Stx1(n = 1), Stx2 (n = 3), eaeA (n = 4) and hlyA (n = 3) genes. Plasmid incompatibility (Inc) typing revealed that two isolates harboured blaNDM-5 gene on Incl1 and one isolate on IncF plasmid. Apart from the NDM gene, the plasmids also carried tetracycline, beta-lactamase and quinolone resistance genes. The plasmid multilocus sequence typing (pMLST) of the E. coli Incl1 plasmid showed the Sequence Type (ST) 297. This appears to be the first report of MDR, ESBL producing and blaNDM-5 genes on Incl1 and IncF plasmids from rescued sloth bear.

Abstract
The gut microbiota composition and dietary factors in our food along with the use of prebiotics and probiotics play an important role in the maintenance of human health. A well-balanced gut microbial population is necessary for the host and the microbiota to coexist in a mutually beneficial relationship maintaining homeostasis. Considering the potential of modern technological tools, it is possible nowadays to engineer prebiotic bacteria having a positive influence on the microbiome on one hand while on the other one may have the ease to get rid of the pathogenic proinflammatory microbes or elements causing dysbiosis. Past studies have seen that in cancer there is a loss of inter-microbial relationship cum interactions within microbiota members, the metabolic products produced by them and the host immune system in a microbial ecosystem, leading to dysbiosis. Current review highlights the importance of probiotics in the management of cancer by bringing together majority of the studies together at a single platform and moreover, stresses upon the need to maintain eubiosis in order to evade and inhibit the progression of cancer. Continuous expansion in knowledge about probiotics, their effect on various cancers and the underlying mechanism of action has raised the global scientific interest towards their possible use against different cancers. Furthermore, the article emphasizes upon the need to explore newer therapeutic targets comprising of the microbiome which could further pave the way to the concept of personalized medicines for various kinds of malignancies so as to derive maximum benefits of a treatment modality and to preserve the microbial homeostasis.

Abstract
Any alteration at the genetic or epigenetic level, may result in multiplex of diseases including tumorigenesis which ultimately results in the cancer development. Restoration of the normal epigenome by reversing the epigenetic alterations have been reported in tumors paving the way for development of an effective epigenetic treatment in cancer. However, delineating various epigenetic events has been a challenging task so far despite substantial progress in understanding DNA methylation and histone modifications during transcription of genes. Many inhibitors in the form of epigenetic drugs mostly targeting chromatin and histone modifying enzymes including DNA methyltransferase (DNMT) enzyme inhibitors and a histone deacetylases (HDACs) inhibitor, have been in use subsequent to the approval by FDA for cancer treatment. Similarly, other inhibitory drugs, such as FK228, suberoylanilide hydroxamic acid (SAHA) and MS-275, have been successfully tested in clinical studies. Despite all these advancements, still we see a hazy view as far as a promising epigenetic anticancer therapy is concerned. The challenges are to have more specific and effective inhibitors with negligible side effects. Moreover, the alterations seen in tumors are not well understood for which one has to gain deeper insight into the tumor pathology as well. Current review focusses on such epigenetic alterations occurring in cancer and the effective strategies to utilize such alterations for potential therapeutic use and treatment in cancer.

Abstract
The study aimed to investigate the occurrence of carbapenem resistant E. coli and P. aeruginosa in apparently healthy, captive blackbucks and leopards of India. Faecal samples of blackbucks (n = 7) and leopards (n = 7) were processed to isolate carbapenem resistant E. coli (CRE) and P. aeruginosa (CRP). Forty (leopards n = 26; blackbuck n = 14) E. coli and two P. aeruginosa (blackbuck n = 2) samples were isolated from the faecal samples (n = 14). Eleven carbapenem resistant isolates were recovered, of which 10 were CRE and one was CRP. The minimum inhibitory concentration (MIC) was determined for meropenem for carbapenem resistant isolates and was between 8 and 64 μg/mL. All the CRE and CRP were phenotypically multidrug resistant, and six CRE were extended-spectrum beta-lactamases (ESBL) producers. On genotypic screening, seven CRE and one CRP were positive for the blaNDM carbapenemase gene. Efflux pump-mediated carbapenem resistance was noticed in four CRE isolates (36.4%, 4/11). Of the six ESBL producing CRE, four isolates carried blaCTX-M-1 genes. The CRE isolates also harbored blaTEM-1, blaAmpC, qnrA, qnrB, qnrS, tetA, tetB and sul1 resistance genes. On Shiga toxin virulence screening, Stx1, Stx2 genes were detected in two and one isolates, respectively. Plasmid typing of CRE revealed that the blaNDM genes were carried on an Incl1 plasmid. The plasmid multilocus sequence typing (pMLST) of the isolates showed the Sequence Type (ST) 297. The occurrence of carbapenem resistance bacteria in captive wildlife should be a major public health priority.

Abstract
A dual trace intra-pulse and inter-pulse spatio-spectral interferometer has been set up to study the temporal stability of a ∼200 fs duration laser pulse train from a cw mode-locked laser oscillator. Simultaneous recording of twin interferograms helps identify the phase error in inter-pulse interferograms due to the diagnostic setup kept in a standard laboratory environment. Applicability of inter-pulse tilted pulse-front interferograms has been demonstrated to constitute an alternative inexpensive method for visual detection and estimation of phase slippage and pulse repetition frequency of an ultra short pulse train. The effect of pump beam intensity on the repetition rate of pulses due to accumulated intra-cavity non-linear phase shifts is also presented.

Abstract
Expression levels of 13 microRNAs (miRNAs) were compared between buffalo blastocysts produced by somatic cell nuclear transfer through hand-made cloning and IVF to improve cloning efficiency. Expression of miR-22, miR-145, miR-374a and miR-30c was higher, whereas that of miR-29b, miR-101, miR-302b, miR-34a, miR-21 and miR-25 was lower, in nuclear transferred (NT) than IVF embryos; the expression of miR-200b, miR-26a and miR-128 was similar between the two groups. Based on these, miR-145, which is involved in the regulation of pluripotency, was selected for further investigation of NT embryos. miR-145 expression was lowest at the 2-cell stage, increased through the 4-cell stage and was highest at the 8-cell or morula stage in a pattern that was similar between NT and IVF embryos. miR-145 expression was higher in NT than IVF embryos at all stages examined. Treatment of reconstructed embryos 1h after electrofusion with an inhibitor of miR-145 for 1h decreased the apoptotic index and increased the blastocyst rate, total cell number, ratio of cells in the inner cell mass to trophectoderm, global levels of acetylation of histone 3 at lysine 18 and expression of Krueppel-like factor 4 (KLF4), octamer-binding transcription factor 4 (OCT4) and SRY (sex determining region Y)-box 2 (SOX2) in blastocysts. Treatment with an miR-145 mimic had the opposite effects. In conclusion, treatment of NT embryos with an miR-145 inhibitor improves the developmental competence and quality, and increases histone acetylation and expression of pluripotency-related genes.

Abstract
Bioengineered scaffolds derived from the decellularized extracellular matrix (ECM) obtained from discarded animal organs and tissues are attractive candidates for regenerative medicine applications. Tailoring these scaffolds with stem cells enhances their regeneration potential making them a suitable platform for regenerating damaged tissues. Thus, the study was designed to investigate the potential of mesenchymal stem cells tailored acellular bubaline diaphragm and aortic ECM for the repair of full-thickness abdominal wall defects in a rabbit model. Tissues obtained from bubaline diaphragm and aorta were decellularized and bioengineered by seeding with rabbit bone marrow derived mesenchymal stem cells (r-BMSC). Full-thickness abdominal wall defects of 3 cm × 4 cm size were created in a rabbit model and repaired using five different prostheses, namely, polypropylene sheet, nonseeded diaphragm ECM, nonseeded aorta ECM, r-BMSC bioengineered diaphragm ECM, and r-BMSC bioengineered aorta ECM. Results from the study revealed that biological scaffolds are superior in comparison to synthetic polymer mesh for regeneration in terms of collagen deposition, maturation, neovascularization, and lack of any significant (P > 0.05) adhesions with the abdominal viscera. Seeding with r-BMSC significantly increased (P < 0.05) the collagen deposition and biomechanical strength of the scaffolds. The bioengineered r-BMSC seeded acellular bubaline diaphragm showed even superior biomechanical strength as compared to synthetic polymer mesh. Tailoring of the scaffolds with the r-BMSC also resulted in significant reduction (P < 0.01) in antibody and cell mediated immune reactions to the xenogeneic scaffolds in rabbit model.

Abstract
A total of 57 tissue samples of domestic pigs (Sus scrofa) were collected from the meat outlets of five north Indian states and examined for sarcocystosis by histological and molecular methods. The genomic DNA extracted from five representative positive isolates was subjected to PCR amplification of the partial 18S rRNA gene followed by cloning and sequencing. Sequence analysis of the newly generated Indian isolates recorded 96.9-100.0% identity with published sequences of Sarcocystis suihominis. Two new haplotypes that have not been previously described manifested 99.5-100.0% nucleotide homology within themselves. In the phylogenetic analysis, Indian isolates of S. suihominis grouped together with S. suihominis originating from Italy, and they collectively formed a sister clade with Sarcocystis miescheriana within a clade containing various Sarcocystis spp. of ruminants having felids as final hosts. At the same time, this clade separated from a sister clade containing Sarcocystis spp. of bovid or cervid ruminants using canids as known or surmised definitive host. The current study established the phylogenetic relationship of Indian isolates of S. suihominis with various Sarcocystis spp. as well as with other taxa of Sarcocystidae family based on 18S rRNA gene for the first time.

Abstract
The objective of this study was to assess the efficacy of knotless barbed sutures in intraoral wound closure for maxillofacial trauma in comparison with conventional (vicryl) sutures. This was a randomised controlled clinical trial involving 40 patients with isolated mandibular angle fractures who required intraoral incisions for open reduction and internal fixation (ORIF). The sample was randomised into the study group (20 patients) and control group (20 patients). Following fracture fixation by a standardised surgical protocol, the wound closure was done with bidirectional knotless barbed suture and vicryl for the study and control groups, respectively. The wounds were closed in layers (periosteum and mucosa). All operations were performed by a single surgeon. Outcome parameters measured were intraoperative wound closure time and wound healing using 'Landry's wound healing index' on the first, third, and seventh postoperative days. Statistically significant difference in suturing time was noted between the study and control group (p value <0.001). The study group demonstrated a mean (SD) suturing time of 9.46 (2.01) minutes, compared with the 17.61 (2.57) minutes in the control group. Wound healing was found to be better and statistically significant in the study group than the control group (p value<0.001). Knotless barbed suture is a promising alternative to vicryl for intraoral wound closure.

Abstract
OBJECTIVES As per National AIDS Control Organization (NACO) estimates, there are 2.1 million people living with HIV (PWH) in India, of whom 1.2 million are on first-line antiretroviral therapy (ART). This study explored the use of a single-tablet regimen containing tenofovir disoproxil fumarate 300 mg + lamivudine 300 mg + efavirenz 400 mg (TLE400 STR) as a first-line switch strategy in PWH in Pune, India. METHODS This retrospective cohort study was conducted in private sector ART clinics in three tertiary-level hospitals in Pune, India. PWH > 12 years of age (n = 502) who initiated first-line ART (predominantly TLE600 STR), completed ≥ 6 months of follow-up and achieved virological suppression [plasma viral load (VL) < 1000 HIV-1 RNA copies/mL] were identified and switched to TLE400 STR. The virological and immunological efficacy of TLE400 STR at 6 and 12 months of follow-up were noted. Grade 3/4 adverse events (especially efavirenz-related neuropsychiatric adverse events) leading to regimen discontinuation were also noted. RESULTS Of 502 PWH who switched to TLE400 STR, complete virological suppression (VL < 20 copies/mL) was maintained in more than 97% of patients at follow-up. TLE400 STR was successful in maintaining CD4 counts within the range observed at the start of the regimen. Grade 3/4 adverse events leading to TLE400 STR discontinuation were seen in 11 (2.2%) patients. Virological failure (VL > 1000 copies/mL) and treatment regimen failure were seen in six (1.2%) and 49 (9.8%) subjects, respectively. CONCLUSIONS TLE400 STR exhibits excellent efficacy and safety as a switch strategy and should be introduced in the Indian National ART Program, especially for PWH who are virologically suppressed on TLE600 STR.
