Abstract
INTRODUCTION Gastrointestinal (GI) lipomas are rare; however, they are frequent enough to be considered in the differential diagnosis of gut tumours. Here, we present our experience with GI lipomas managed at our institute over the last three years. METHODS This is a retrospective cohort study of patients with GI lipomas managed between January, 2020 and April, 2023 at a tertiary care centre. Clinical presentation, location, and details of surgical procedure were analysed. RESULTS Ten patients were included, six of whom had lipoma in the colon, one in the stomach, and one each in the duodenum, jejunum, and ileum. The mean age at the time of presentation was 48.8 years (range, 19-77 years), and strong male preponderance (4:1) was noted. Preoperative diagnosis of lipoma on cross-sectional imaging was possible in all patients. All patients were symptomatic and were managed surgically. CONCLUSIONS While GI lipomas are generally considered to be indolent and benign tumours, they can potentially lead to severe complications. The utilisation of computed tomography and magnetic resonance imaging has brought about a significant transformation in diagnosing this condition, enabling preoperative identification in most cases. The surgery offers a definitive treatment with minimal risk of postoperative complications.

Abstract
Arylpiperazine clubbed various heterocyclic molecules present potential pharmacophoric structural features for the development of psychoactive drugs. There are various CNS active molecules possessing arylpiperazine moiety in their pharmacophore approved by USFDA. In the current study, we have explored the benzhydrylpiperazine moiety clubbed with various substituted oxadiazole moieties (AP1-12) for their monoamine oxidase (MAO) inhibition and antidepressant potential. Compounds AP3 and AP12 exhibited highly potent and selective MAO-A inhibition with IC50 values of 1.34 ± 0.93 µM and 1.13 ± 0.54 µM, respectively, and a selectivity index of 10- and 13-folds, respectively. Both the compounds displayed reversible binding character at the active site of MAO-A. In further in vivo evaluation, both the compounds AP3 and AP12 displayed potential antidepressant-like character in FST and TST studies via significantly reduced immobility time in comparison to non-treated animals. These compounds displayed no cytotoxicity in SH-SY5Y cell lines, which indicates that these compounds are safe for further evaluation. In silico studies reveal that synthesized compounds possess drug-likeness with minimal to no toxicity. In silico studies were conducted to understand the binding interactions and stability of compounds at the binding pocket of enzyme and observed that both the best compounds fit well at the active site of MAO-A lined by amino acid residues Tyr69, Asn181, Phe208, Ile335, Leu337, Phe352, and Tyr444 similar to standard MAO-A inhibitor clorgiline. The molecular dynamic studies demonstrated that AP3 and AP12 formed quite a stable complex at the active site of MAO-A and did not break under small abruption forces. The favourable binding interactions and appropriate ADMET properties present the benzhydrylpiperazine clubbed oxadiazole pharmacophoric features as a potential structural skeleton for further clinical evaluation and development of a new antidepressant drug molecule.

Abstract
Depression is one of the key conditions addressed by the Mental Health Gap Action Programme (mhGAP) of WHO that can lead to self-harm and suicide. Depression is associated with low levels of neurotransmitters, which eventually play a key role in the progression and development of mental illness. The nitrogen-containing heterocyclic compounds exhibit the most prominent pharmacological profile as antidepressants. Pyrazoline, a dihydro derivative of pyrazole, is a well-known five-membered heterocyclic moiety that exhibits a broad spectrum of biological activities. Many researchers have reported pyrazoline scaffold-containing molecules as potential antidepressant agents with selectivity for monoamine oxidase enzyme (MAO) isoforms. Several studies indicated a better affinity of pyrazoline-based moiety as (monoamine oxidase inhibitors) MAOIs. In this review, we have focused on the recent advancements (2019-2023) in the development of pyrazoline-containing derivatives exhibiting promising inhibition of MAO-A enzyme to treat depression. This review provides structural insights on pyrazoline-based molecules along with their SAR analysis, in silico exploration of binding interactions between pyrazoline derivatives and MAO-A enzyme, and clinical trial status of various drug molecules against depression. The in-silico exploration of potent pyrazoline derivatives at the active site of the MAOA enzyme will provide further insights into the development of new potential MAO-A inhibitors for the treatment of depression.

Abstract
Depression is not similar to daily mood fluctuations and temporary emotional responses to day-to-day activities. Depression is not a passing problem; it is an ongoing problem. It deals with different episodes consisting of several symptoms that last for at least 2 weeks. It can be seen for several weeks, months, or years. At its final stage, or can say, in its worst condition, it can lead to suicide. Antidepressants are used to inhibit the reuptake of the neurotransmitters by some selective receptors, which increase the concentration of specific neurotransmitters around the nerves in the brain. Drugs that are currently being used for the management of various types of depression include selective serotonin reuptake inhibitors, tricyclic antidepressants, atypical antidepressants, serotonin, noradrenaline reuptake inhibitors, etc. In this review, we have outlined different symptoms, causes, and recent advancements in nitrogen-containing heterocyclic drug candidates for the management of depression. This article highlights the various structural features along with the structure-activity relationship (SAR) of nitrogen-containing heterocyclics that play a key role in binding at target sites for potential antidepressant action. The in silico studies were carried out to determine the binding interactions of the target ligands with the receptor site to determine the potential role of substitution patterns at core pharmacophoric features. This article will help medicinal chemists, biochemists, and other interested researchers in identifying the potential pharmacophores as lead compounds for further development of new potent antidepressants.

Abstract
Inflammation is the human body's defence process against various pathogens, toxic substances, irradiation, and physically injured cells that have been damaged. Inflammation is characterized by swelling, pain, redness, heat, as well as diminished tissue function. Multiple important inflammatory markers determine the prognosis of inflammatory processes, which include likes of pro-inflammatory cytokines which are controlled by nuclear factor kappa-B (NF-kB), mitogen-activated protein kinase (MAPK), Janus kinase signal transducer and activator of transcription (JAK-STAT) pathway, all of which are activated in response to the stimulation of specific receptors. Besides these, the cyclooxygenase (COX) enzyme family also plays a significant role in inflammation. The current review is kept forth to compile a summary of small molecules-based drugs approved by the USFDA during the study period of 2013-2023. A thorough discussion has also been made to focus on biologics, macromolecules, and small chemical entities approved during this study period and their greener synthetic routes with a brief discussion on the chemical spacing parameters of anti-inflammatory drugs. The compilation is expected to assist the medicinal chemist and the scientist actively engaged in drug discovery and development of anti-inflammatory agents from newer perspectives during the current years.

Abstract
Neurodegenerative disorders (NDDs) are multifaceted complex disorders that have put a great health and economic burden around the globe nowadays. The multi-factorial nature of NDDs has presented a great challenge in drug discovery and continuous efforts are in progress in search of suitable therapeutic candidates. Nature has a great wealth of active principles in its lap that has cured the human population since ancient times. Natural products have revealed several benefits over conventional synthetic medications and scientists have shifted their vision towards exploring the therapeutic potentials of natural products in the past few years. The structural mimicking of natural compounds to endogenous ligands has presented them as a potential therapeutic candidate to prevent the development of NDDs. In the presented review, authors have summarized demographical facts about various NDDs including Alzheimer's disease (AD), Parkinson's disease (PD), Huntington's disease (HD) and various types of sclerosis in the brain. The significant findings of new active principles of natural origin along with their therapeutic potentials on NDDs have been included. Also, a description of clinical trials and patents on natural products has been enlisted in this compilation. Although natural products have shown promising success in drug discovery against NDDs, still their use is associated with several ethical issues which need to be solved in the upcoming time.

Abstract
Irritable Bowel Disorder (IBD) is a prevalent digestive illness that frequently affects young people and drastically decreases the Quality of Life (QoL). Adults with IBD indications may find relief from their symptoms through nutritional changes like the Mediterranean-style diet. Concerning the seriousness of symptoms, QoL, and additional pertinent results in young people with IBD, this investigation seeks to determine the impact of the Mediterranean-style diet. 200 individuals with IBD who met the Rome-IV criterion and were between the ages of 13 and 19 were enrolled in the present research. A Mediterranean-style diet was provided to the Study Group (SG), which consisted of 100 individuals, while the Control Group (CG), which consisted of 100 patients, followed the usual diet. Various laboratory and clinical characteristics were also assessed at the beginning and end of the study, in addition to IBD values. The Mediterranean-style diet has been demonstrated to be effective and tolerated well in kids and teenagers with IBD. The IBD -SSS (from 148±42.3 to 224±71) IBD -QoL (from 76.7±8.1 to 61.3±9.8), and cumulative IBD rating (from 29.3±11.7 to 32.6±12.1) all showed notable increases in individuals who followed well to this diet. The CG, in comparison, did not show any significant enhancements in these factors. This indicates that a Mediterranean-style diet might provide therapeutic advantages for IBD individuals, especially those who keep adherent to it, concerning symptom severity and QoL. The Mediterranean-style diet proved to be both secure and associated with notable improvements in IBD rates in young and adolescents with IBD.

Abstract
Separating aneurysmal arterial disease from atherosclerosis and further occlusive artery conditions, it is a vascular degenerative disorder. Within the vascular tree, there is a regionalization of the propensity to produce aneurysms and the different locations result in different clinical processes. As the predominant risk factor for ubrenal abdominal aortic aneurysm (AAA), smoking is one of the most common manifestations of aneurysmal illness. For AAA compared to atherosclerosis, smoking is a far bigger risk factor. Along with contributing to the pathophysiology of AAA, smoking raises the likelihood that established AAA will rupture as well as its rate of expansion. The development of improved models for animals that are reliant on smoke or smoke constituents is helping to determine the mechanistic connection between AAA and smoking. According to the processes, there are long-lasting changes in the function of inflammatory and vascular smooth muscle cells. Focused on AAA, this review looks at the medical, epidemiology and mechanical evidence that links smoking to aneurysms.

Abstract
Aim - determining the prevalence of anxiety disorders and their effect on disease progression and quality of life in adults with organic illnesses and functional disorders of the respiratory system treated in a pulmonology environment. A total of 135 young adults between the ages of 13 and 17 were analyzed. There were a total of 46 adolescents diagnosed with somatoform respiratory disorders (SRD), 45 adolescents diagnosed with bronchial asthma (BA), and 44 adolescents diagnosed with pneumonia. The Spielberger-Khanin anxiety questionnaire and the Nijmegen hyperventilation syndrome (HVS) scale were used for the research and diagnosis, respectively. The quality of life was measured using the asthma quality of life questionnaire (AQLQ). In comparison to adults with asthma (33.2%) and pneumonia (32.3%), adults with SRD (34.5%). There were mild immediate associations between the Spielberger scale and the Nijmegen HVS questionnaire for both trait and state anxiety, and mild inverse correlations between the Spielberger scale and the AQLQ for both state and trait anxiety. Adolescents with anxiety had a higher prevalence of trauma, pain, and social issues than their non-anxious counterparts who were referred to psychiatry. In adolescents, 5.1% had severe trait anxiety, and 19.3% had severe condition anxiety. Adolescents with SRD were twice as likely to suffer from extreme state and trait anxiety as the general population. It is hypothesized that anxiety problems are at the root of HVS and contribute to adults' dissatisfaction with their quality of life due to lung ailments. Although certain adolescents with anxiety disorders were referred for anxiety, this data nevertheless lends credence to the idea that using standardized and structured instruments regularly might help increase accuracy and detection rates in the clinic, regardless of the reason for referral. Complete evaluations are essential for this patient population due to the intricacy of their symptoms.

Abstract
A major issue among adolescents in recent years has been social isolation, or the sensation cut off and alone from peers and society. The effects of social isolation on youngsters and adolescents are investigated with special attention paying to the possible negative effects on their physical and mental health. Multiple studies have shown a link between adversity in life domains and adolescent social isolation. Firstly, it can have a major effect on mental health, raising the probability of experiencing things like anxiety, sadness and even suicidal thoughts. Second, it prevents the development of vital social abilities, making it harder to make and keep close friends. In addition, social isolation is associated with worse academic performance, which in turn reduces the number of courses a student can take and the number of jobs they can have in the future. After looking over 520 papers, 15 were chosen for the systematic review. Four researches reported the implications on general health, while two investigations reported on ramifications affecting the Hypothalamic-pituitary-adrenal (HPA) axis area along with social and mental growth of children. In conclusion, social isolation affects youth development across a wide spectrum, including psychological well-being, interpersonal skills, and academic success. Children and adolescents who experience isolation are more likely to suffer from anxiety and sadness, according to the review's findings. Cortical levels rise and mental growth slows in socially isolated children. Children and adolescents should be monitored by health professionals during and after the COVID-19 pandemic to ensure that their mental and physical health needs are met.

Abstract
Ischemic stroke is a major health issue, especially for the older population and it may have severe effects. Stroke diagnosis and treatment have advanced over the last 20 years, which has resulted in considerable reductions in death, long-term impairment, and the need for institutional care. Younger age groups have seen the majority of trials for acute, interventional, and preventive therapy. The purpose of this research was to identify distinct subgroups of older people who had suffered an ischemic stroke and examine the role that risk factors and previous illnesses played in their development. Ischemic stroke risk factors varied by age, gender and exhibited their own unique features. Smoking, cholesterol, and psychological/emotional stress were shown to have the greatest prevalence (p<0.06) among stroke patients aged 45-60. Smoking is associated with a significant (p<0.07) decline in health in elderly people. Our results imply that there are significant patterns of risk factors and preexisting illnesses among the various subgroups of older people who have had an ischemic stroke. Atherosclerotic (large-artery) and cardio embolic (small-artery) ischemic strokes were shown to be the most prevalent among the elderly. Strong associations were found between these subtypes and other risk factors, including higher cholesterol, diabetes, high blood pressure, and atrial fibrillation. This research emphasizes the need for individualized preventative methods and therapeutic therapy, as well as the need to recognize the variability of ischemic stroke in the elderly.

Abstract
A fast implant is a kind of implant to place in the cavity right away after dental extraction. These implants are shown to maintain cervical marrow and reduce the number of surgery operations required for patients. The Photodynamic treatment (PDT) uses antimicrobial processes to supplement nonsurgical periodontal therapy. Combined through the scaling and root planning (SRP), and PDT is more effective. This study aims to assess the effects of PDT on initial findings with dental implants (DI) placed in patients having gum disease with SRP against patients who do not at the 12-month follow-up point. An aggregate of 25 implants were inserted in 16 patients, 12 of whom were in the test group (TG) and 13 of whom were in the control group (CG). SRP is conducted toward rapid implant assignment in the control site, while PDT as an adjunct to SRP (SRP + PDT) is executed prior to instant implant insertion in test sites. At the beginning, 4 months, 8 months, and 12 months, gingival index, radiovisiographs, inquiring pocket intensity, clinical attachment level, and plaque index were obtained. Basic durability was assessed after implant insertion, and the recovery index was measured a week later. In this analysis, Analysis of Variance (ANOVA) technique is used to predict tooth decay earlier. The CG experienced 1.10 mm of mean marginal bone loss after the 12-month research period, compared to 0.97 mm for the (SRP + PDT) group. After reaching the CG and TG, the differences in plaque score and probe depth were noteworthy. Clinical indicators compared to the basis in a year revealed unquestionable improvement, including the probing depth gingival index, plaque index and clinical attachment level. Twelve months were spent monitoring the implants in both groups. The little bone loss improved, although it isn't clinically important. The endurance rate for rapid implants in the PDT grouping is the same as that of the group that underwent SRP. The impact of PTD is utilized as a supplement to SRP. Yet, the consequence is marginal. Because of the improved results with PDT, it is used successfully as an addition to SRP.

Abstract
BACKGROUND Ginseng (Panax ginseng) is a herb of medicinal and nutritional importance. Ginseng has been used since ancient times for the treatment of numerous ailments as it has many therapeutic properties. Several phytoconstituents are present in Panax ginseng that possess a variety of beneficial pharmacological properties. OBJECTIVE To explore the potential of phytoconstituents of Panax ginseng in the treatment of depression, a molecular modeling technique was utilized targeting monoamine oxidase-A (MAOA). METHODS A total of sixty-one phytoconstituents of ginseng were drawn with the help of ChemBioDraw Ultra 12.0 software and PDBs for MAO-A enzyme were retrieved from the RCSB PDB database. The prepared ligands were screened for MAO-A properties using the software Molegro Virtual Docker (MVD 2010.4.1.0). All the prepared ligands were evaluated for drug-likeliness properties using Swiss ADME. RESULT Among the docking studies of 60 Ginseng phytochemicals including one standard, 15 phytoconstituents with the highest dock score and better binding interactions were selected further for absorption, distribution, metabolism and excretion (ADME) studies. Stachyose (-227.287, 17 interactions), Raffinose (-222.157, 14 interactions), and Ginsenoside Rg1 (-216.593, 10 interactions) were found to possess better interactions as compared to Clorgyline taken as a standard drug. CONCLUSION Stachyose was found to be the most potent inhibitor of MAO-A enzyme under investigation and can be a potential lead molecule for the development of newer phytochemical-based treatment of depression.

Abstract
PURPOSE/OBJECTIVE(S) CAR-T cell therapy is limited by toxicity, high cost, logistical manufacturing issues in the autologous setting and risk of GVHD in the allogeneic setting. Substitution of T cells with NK cells opens the possibility for an allogeneic off-the-shelf product with a better safety profile. However, the inadequate efficacy of CAR-NK cells against solid tumors can be extrapolated from experience with CAR-T cells. There is limited but promising preclinical evidence that radiation therapy (RT) enhances CAR-T cell tumoricidal activity against solid tumors. However, there is no data examining the potential synergy between RT and CAR-NK cell therapy. MATERIALS/METHODS We engineered CAR-NK cells with CD27 receptor as extracellular domain to target its natural ligand CD70, which is overexpressed in head-and-neck cancers (HNSCC). CAR-NK cell killing was assessed real-time through xCELLigence cytotoxicity assays. CD70+ OQ01 human HNSCCs were used for most experiments. FaDu is a CD70- HNSCC (negative ctrl). UMRC3 is a CD70+ kidney cancer cell line (positive ctrl). CD70 expression pre- and post-RT was assessed by flow cytometry and Western blot. Ionizing RT was compared at 5 doses: 0, 1.75, 3.5, 7, and 14 Gy. A single dose of 3.5 Gy was used for most experiments. Post-radiation effects were generally assessed at 3 days or 9 days post-RT. Intracellular staining was used to assess NK cell expression of IFN-γ, CD107a, and TNF-α by flow cytometry. CD27/CD70 interaction blockade was through α-CD27 pre-treatment of CAR-NK cells. RESULTS OQ01 HNSCCs heterogeneously express CD70 and are killed by CD70 CAR-NK cells in vitro. Pre-conditioning low-dose RT of 3.5 Gy applied to OQ01 HNSCCs 3 days prior to coculture with NK cells enhances CD70 CAR-NK cell killing, with ∼30% increased cytotoxicity against the tumor cells. Low-dose RT by itself did not induce acute cytolysis. As a possible mechanism for the increased sensitivity of irradiated OQ01 cells to CD70 CAR-NK cells, we found that RT enhances CD70 expression among HNSCCs in a dose-dependent manner. There was no increase in NK cell expression of IFN-γ, CD107a, and TNF-α with exposure to irradiated target cells. CD27/CD70 blockade does not solely abrogate RT-induced sensitization toward CAR-NK cell killing. Despite RT induction of transient increased expression of CD70, which normalizes by 9 days post-RT, there is persistent increase in RT-synergized target cell killing even at this later timepoint. Thus, altogether, RT sensitizes CD70-expressing HNSCC cells to CAR-NK cell killing in vitro. CONCLUSION This work represents the first preclinical study to identify the synergy of RT and CAR-NK cell therapy in solid tumors and is the first demonstration of CAR-NK cell activity against human HNSCCs. We show significantly enhanced potency of CAR-NK cells against irradiated tumor cells in vitro. Collectively, this research will be vital to guide efforts expanding into other target antigens and tumor types.

Abstract
The Corona Virus (COV-19) epidemic significantly affected the educational environment, requiring a quick transition to distance and blended learning methods. This extraordinary disruption had an incredible impact on pupil's levels of physical activity (PA), psycho-emotional health (PEH) and engagement with academic material. The research aims to examine the vital determinants that influenced various areas of learners' lives during CoV-19. The purpose of this 600-person study was to collect data on the subjects' overall health and PA levels for the CoV-19 pandemic. The SPSS application was used to process the questionnaire's collected data. The information given reveals the respondents' degree of PA throughout the quarantine. According to the breakdown, 15% indicated low levels of PA, 39% reported medium levels and 46% reported high levels. The data show that, despite the respondents' different levels of PA, little PA predominated for most of them. The limitations of distance learning throughout quarantine and the prevalent recommendation of leaving residence for necessary reasons were blamed for this tendency. There were fewer prospects for higher-intensity PA due to these circumstances.

Abstract
β-Thalassemia major is an inherited blood condition marked by a serious anemia and a lifetime need for blood transfusions. The effects of β-thalassemia major on endocrine health, notably the risk of diabetes, remain largely unstudied, despite the fact that its haematological components are established. The purpose of this systematic analysis was to examine the incidence of reduced metabolism of glucose in β--thalassemia major. The articles were under the inclusion requirements, after which the data was retrieved. The main outcome was determined to be every prevalence (P) of DM (diabetes mellitus) in β-thalassemia major. In order to examine the percentage of aberrant glucose metabolism (GM) with individuals among β-thalassemia major, the P with the 95% CI (Confidence Interval) was utilized. In this retrospective investigation, we looked at a cohort of people with β-thalassemia major diagnoses to determine the incidence and risk of hormonal diseases, particularly diabetes. A specialist thalassemia facility treated 315 individuals with β-thalassemia major, and their medical records were examined. Age, gender, age at which a main diagnosis of β-thalassemia was made, the length of transfusion treatment, and concomitant diseases were gathered as part of the demographic and clinical data. Our research, which included 17 studies and 1500 cases altogether, showed that with β -thalassemia major had a considerably greater frequency of diabetes than people in general. With a mean beginning age of 30 years, diabetes was identified in 28% of the research cohort's participants. The combined meta-analysis showed that each year had a rather stable level of DM P in β-thalassemia major. In people with major β-thalassemia, the P of impaired fasting glucose (IFG), DM, and impaired glucose tolerance (IGT) was 17.22% (95% CI: 8.44%-26.02%), (6.57 (95% CI: 5.31%- 7.79%) and 12.47 % (95% CI: 5.97%-18.95%), respectively. Our research suggests that people with β-thalassemia major have a high chance of acquiring diabetes, particularly if they get extended transfusion treatment. For prompt diagnosis and care, early detection of diabetes and other hormonal problems in this group is crucial. In β-thalassemia major, there is a high frequency of endocrine problems, including improper GM. To stop growth and endocrine issues, treatment and preventative measures can be required.

Abstract
Parkinson's Disease in Mild Cognitive Impairment (PD-MCI) is a complex condition characterized by a variety of cognitive problems that coexist with the physical symptoms of Parkinson's disease (PD). This study aims to examine the different medical indicators and associated tendencies among different PD-MCI groups. We investigated 132 people who had been given PD-MCI diagnoses. Utilizing SPSS, statistical evaluations are carried out. In overall PD-MCI variants, this investigation found that visuospatial ability and attentional/executive performance are the most impaired cognitive areas. It was also noticed that distinct PD-MCI groups had variances in their neurological characteristics, in multi domain amnesia (Non-Memory) PD-MCI patients exhibiting especially severe issues with unstable posture and walking. The intricacy of PD- Mild Cognitive Impairment (MCI) is highlighted by those results, which also imply that the interplay between mental and physical signs may be controlled by a number of interrelated factors, such as particular cognitive areas, brain surfaces, and the general level of cognitive impairment.

Abstract
Serotoninergic signaling is identified as a crucial player in psychiatric disorders (notably depression), presenting it as a significant therapeutic target for treating such conditions. Inhibitors of serotoninergic signaling (especially selective serotonin reuptake inhibitors (SSRI) or serotonin and norepinephrine reuptake inhibitors (SNRI)) are prominently selected as first-line therapy for the treatment of depression, which benefits via increasing low serotonin levels and norepinephrine by blocking serotonin/norepinephrine reuptake and thereby increasing activity. While developing newer heterocyclic scaffolds to target/modulate the serotonergic systems, imidazole-bearing pharmacophores have emerged. The imidazole-derived pharmacophore already demonstrated unique structural characteristics and an electron-rich environment, ultimately resulting in a diverse range of bioactivities. Therefore, the current manuscript discloses such a specific modification and structural activity relationship (SAR) of attempted derivatization in terms of the serotonergic efficacy of the resultant inhibitor. We also featured a landscape of imidazole-based development, focusing on SAR studies against the serotoninergic system to target depression. This study covers the recent advancements in synthetic methodologies for imidazole derivatives and the development of new molecules having antidepressant activity via modulating serotonergic systems, along with their SAR studies. The focus of the study is to provide structural insights into imidazole-based derivatives as serotonergic system modulators for the treatment of depression.

Abstract
ABSTRACT A series of isatin-based fused heterocycles were designed, synthesized, and evaluated for anticancer activity against four cancer cell lines: MCF-7, MDA-MB-231, A549, and HL-60. Among them, Q3 and T4 were found to be potent anticancer agents. Furthermore, two compounds Q3 and T4 were selected for epidermal growth factor receptor (EGFR) inhibitory activity. Two compounds Q3 and T4 were found to be most potent EGFR inhibitors with IC50 of 0.22 ± 0.10 and 0.19 ± 0.07 μM. The EGFR inhibitory activity of standard drug erlotinib was 0.08 ± 0.02 μM. Structural Activity Relationship studies showed that electronegative atoms were necessary for EGFR inhibitory potential. Finally, molecular docking studies were carried out to check the binding pattern of synthesized derivatives with the adenosine triphosphate (ATP) binding site of EGFR and results revealed that compounds Q3 (-9.2 kcal/mol) and T4 (-8.9 kcal/mol) exhibited better binding affinity than reference drug erlotinib (-7.3 kcal/mol).

Abstract
Bathua (Chenopodium album) is a rich source of extensive-ranging nutrients, including bio-active carbohydrates, flavonoids and phenolics, minerals, and vitamins that translate to countless health benefits such as anticancer, antidiabetic, anti-inflammatory, antimicrobial, and antioxidant activity. Ascaridole, an important phytoconstituent present in aerial parts of the plant, contributes to its anthelmintic property. Even with vast historical use and significant health benefits, its renown has not spread, and utilization has significantly decreased in recent decades. Gradually, the plant has become known under the name of Non-conventional edible plant (NCEP). This compilation is prepared to bring out the plant under the spotlight for further research by foregrounding previous studies on the plant. Scientific research databases, including PubMed, Google Scholar, Scopus, SpringerLink, ScienceDirect, and Wiley Online, were used to fetch data on C. album. This review offers over up-to-date knowledge on nutritious values, phytochemical composition, volatile compounds, as well as health benefits of C. album. The ethnobotanical and ethnomedicinal uses of the plant in India and other parts of the world are deliberately discussed. Scrutinizing the reported literature on C. album reveals its powerful nutrient composition advantageous in the development of food products. The impact of various cooking and processing methods on the nutritional profile and bioavailability are discussed. The future perspectives with regards to the potential for food and nutraceutical products are critically addressed. This review proves the necessity of breakthrough research to investigate the pharmacology and safety of phytochemicals and nutraceutical development studies on the C. album.

Abstract
Piperazine derivatives have been of great interest to medicinal chemists in the development of antidepressant drugs due to their distinct molecular and structural features along with their pharmacological profile. In this study, we have designed and synthesized a series of 10 compounds of piperazine clubbed oxadiazole derivatives (5a-j) and screened for their MAO inhibitory activity. Compound 5f and 5 g were found to be the most potent MAO-A inhibitors of the series with IC50 values of 0.96 ± 0.04 µM µM and 0.81 ± 0.03 µM, respectively with a selectivity index of 18-folds and 9-folds over MAO-B isoform. The compounds were found to be reversible inhibitors of MAO-A with no cytotoxicity against SH-SY5Y neuronal cells. The compounds also displayed good antioxidant activity. Further, in vivo TST studies revealed that both the compounds 5f and 5 g possessed good anti-depressant-like activity and reduced the immobility time significantly although were found inactive in FST studies. The molecular docking studies revealed that both compounds fit well at the active site of MAO-A enzyme as similar to clorgyline and form a stable complex. The results were confirmed via molecular dynamic studies which demonstrate the stable complex formation between MAO-A and 5f & 5 g. The appropriate drug-like characteristics with favourable ADMET profile, these molecules presented this piperazine clubbed oxadiazole structural framework as a key pharmacophore for the development of new antidepressant molecules along with strong candidature for further clinical investigations.

Abstract
We have developed a mathematical model and obtained a numerical solution for the motion of a non-Newtonian Maxwell fluid between two disks having rotation and stretching velocity with convective boundary constraints, porous medium and thermal radiation. The present Maxwell fluid flow
model with specified boundary constraints is not discussed so far. The proposed model has a lot of applications in electrical power generation, nuclear energy plants, astrophysical flows, space vehicles, geothermal extractions, and spinning disc reactor. The Von Karman similarity approach
is used for the solution and validation of the solution is also provided. The solution is obtained numerically with finite difference method (FDM) based ND-solve command in Mathematica software. The effects of magnetic field, porous medium, radiation parameter, Deborah number, Prandtl number,
and Reynolds number on skin friction, heat transfer, flow and temperature fields are discussed in detail. Due to the significant void fraction in the medium, porosity parameter shows unique trend compared to other parameters for the radial velocity profile. It has tendency to enhance the radial
velocity near both the disc but in the middle part of system, porosity parameter retards radial velocity significantly.

Abstract
Parkinson's disease is a neurodegenerative disorder characterized by slow movement, tremors, and stiffness caused due to loss of dopaminergic neurons caused in the brain's substantia nigra. The concentration of dopamine is decreased in the brain. Parkinson's disease may be happened because of various genetic and environmental factors. Parkinson's disease is related to the irregular expression of the monoamine oxidase (MAO) enzyme, precisely type B, which causes the oxidative deamination of biogenic amines such as dopamine. MAO-B inhibitors, available currently in the market, carry various adverse effects such as dizziness, nausea, vomiting, lightheadedness, fainting, etc. So, there is an urgent need to develop new MAO-B inhibitors with minimum side effects. In this review, we have included recently studied compounds (2018 onwards). Agrawal et al. reported MAO-B inhibitors with IC50 0.0051 µM and showed good binding affinity. Enriquez et al. reported a compound with IC50 144 nM and bind with some critical amino acid residue Tyr60, Ile198, and Ile199. This article also describes the structure-activity relationship of the compounds and clinical trial studies of related derivatives. These compounds may be used as lead compounds to develop potent compounds as MAO-B inhibitors.

Abstract
OBJECTIVE Conventional use of retraction cord in soft tissue management is effective only when the non-resilient nature of material does not jeopardize gingival health. Therefore this study aims to clinically evaluate the gingival displacement, ease of application and bleeding from polytetrafluoroethylene (PTFE) retraction cord. PATIENTS AND METHODS This study is a single-center, parallel-group, randomized controlled clinical trial (1:1). Sixty patients indicated for full coverage metal-ceramic restoration for first molars were enrolled and randomly allocated to experimental (PTFE Cord) and control (conventional plain retraction cord) groups. After crown preparation and isolation, a pre-displacement impression was made. Assigned gingival displacement material was applied for 5 minutes, followed by post-displacement impression. Casts were prepared and used for assessment of mean horizontal gingival displacement by measuring displacement using a stereomicroscope (20 x). Post-displacement gingival bleeding and ease of application were also assessed clinically. t-test and Chi-square tests were used for statistical assessment of gingival displacement, gingival bleeding and ease of application. RESULTS Gingival displacement, bleeding and ease of application were similar among study groups (p > 0.05). Mean gingival displacement in the experimental group was 197.1 µm, and 167.7 µm in the control group. Bleeding was observed in 30% and 20% of cases of experimental and control group, respectively. Ease of application was 'difficult' in 53.3% and 43.3% of cases of experimental and control group, respectively. Non-impregnated gingival retraction cord and PTFE cord displayed similar outcomes of gingival displacement, ease of placement and bleeding after cord removal. CONCLUSIONS Post-displacement bleeding and discomfort for PTFE cord placement suggest that this technique needs improvement. Therefore further studies are warranted to improve and investigate the physical and biological response to PTFE retraction cord.

Abstract
Background:
Inexpensive and disposable microfluidic sensing equipment is in strong demand which can detect biomarkers of diseases found in urine or blood. From recent studies, it has been found that multifilament threads can be used for producing low-cost microfluidic devices hence these multifilament threads act as an inexpensive alternative. Thread has various advantages to make it appropriate to be used in microfluidics-based technologies which include its low price, lightweight, easy availability, and hydrophilic nature. The use of any external pumping system is avoided by the presence of capillary channels in threads which allows the easy flow of fluid. Since thread offers more choices of materials over paper and also paper-based microfluidics preparation is expensive therefore thread-based microfluidic sensor has been considered more advantageous over paper-based microfluidic sensors.
Methods:
Various research reports were collected from search engines like ScienceDirect, Pub-med, ResearchGate, and Google Scholar. Further important outcomes from these reports along with basic experimental setup details have been compiled under different sections of this manuscript.
Conclusion:
Non-invasive or blood-free diagnosis can reduce the pain and several risk factors compared with the traditional invasive diagnosis so it is gaining more attention regarding health status monitoring. The various applications regarding thread-based devices include the detection of glucose and its determination, diagnosis of diabetes and kidney failure simultaneously, food dyes separation, sweat pH and lactate determination, selective potassium analysis, multiple antibodies detections, an assay of microbes, for acid-base titrations, as ELISA’s platform, diagnosis of infectious diseases, ion sensing, identification of blood types and detection of bio-samples, etc.

Abstract
Cancer represents one of the world's biggest hazardous diseases. p53 is the uttermost researched tumour suppressor protein. It is commonly considered the "guardian of the genome," performing a critical function in genetic stability maintenance through controlling the cell cycle, programmed cell death, DNA repair, aging, and angiogenesis. The abnormalities in p53 lead to genetic instability and plays a significant role in carcinogenesis. The role of p53 in tumour suppression is emphasized in addition by the observation that primary silencing with this protein occurred in more than 50% of cancers. MDM2, p53, and the p53-MDM2 connections are well-known targets for the prevention and treatment of cancer. Moreover, in tumors with wild-type p53, their efficacy is decreased due to MDM2 enlargement or by the gradual decrease of MDM2 blocker ARF. As a result, improving p53 activity in cancerous cells provides a promising anticancer strategy. Various techniques are now being investigated, and addressing the p53-MDM2 interaction had also evolved as a potentially feasible strategy for contending with tumors. Both p53 and MDM2, interact via an autoregulation response signal: p53 activity induces MDM2 transcription, which in response interacts with p53's N-terminal transactivation domain, inhibiting its transcriptional activity. This article provides information on the current scenario of anti-tumor activities, with a particular emphasis on structure-activity relationship characteristics (SAR) against the p53-MDM2 to treat cancer. The primary purpose of this review is to cover recent advancements in the creation and testing of anticancer drugs that target the p53-MDM2 structure. This review contains different heterocyclic moieties which show significant results toward cancer. A mechanistic route is shown here, demonstrating both normal and malignant conditions via several stressed factors. Several compounds entered clinical trials as p53-MDM2 inhibitors for the treatment of cancer.

Abstract
The novel series of substituted-N-(5,6-diphenyl-1,2,4-triazin-3-yl) benzamides (R: 1-12) were designed, synthesized and evaluated for in-vitro and in-vivo antidepressant-like activity. In MAO-A inhibition assay, compound R: 5 and R: 9 displayed most potent activity with IC50 = 0.12 and 0.30 µM. R: 5 and R: 9 were also evaluated for in-vivo antidepressant using FST and TST. In both models, the test samples R: 5 and R: 9 showed noteworthy antidepressant effect. R: 5 showed 46.48 % and 45.96 % reduction in immobility in FST and TST respectively at dosage of 30 mg/kg (p.o). Whereas compound R: 9 reduced the immobility time by 52.76 % and 47.14 % as compared to control in FST and TST, respectively at same dosage. Both the compounds were also tested for behavioural study using actophotometer and grip tests. None of compounds exhibited decrease in locomotor activity. Further, these compounds were subjected to in silico studies to determine their ADME properties along with binding energies and binding orientions. In ADME studies none of the compounds violated the Lipinski rule and all other parameters were also within the acceptable ranges. In docking study R: 5 (-10.7) and R: 9 (-10.4) were also displayed highest docking score. These encouraging results present the pharmacophoric features of substituted-N-(5,6-diphenyl-1,2,4-triazin-3-yl) benzamides as interesting lead for further development of new antidepressant drug molecules.

Abstract
The severity and prevalence of cancer in modern time are a huge global health burden. Continuous efforts are being made toward the development of newer therapeutic candidates to treat and manage this ailment. The dihydropyrimidinone scaffold is one of the key nuclei that have been highly explored and investigated against cancer. It has the potential to combat the consequences of cancer by interacting with several biological targets. Tubulin polymerization inhibition is one such strategy to prevent the progression of cancer. In the presented work, we have synthesized a series of sixteen dihydropyrimidinone derivatives by following a rational drug design. The synthesized compounds have been characterized by 1H NMR and 13C NMR and were further evaluated for cytotoxic activity against breast cancer cell lines (MCF-7 and MDA-MB-231), lung cancer cell lines (A549), and colon cancer cell lines (HCT-116). Compounds 5D and 5P were found most potent and revealed a better cytotoxic activity compared with the standard drug colchicine. Furthermore, the tubulin polymerization inhibition assay revealed that compound 5D showed better inhibition than colchicines, whereas compound 5P revealed an almost equal inhibition to that of colchicine. Furthermore, to investigate the possible mode of action and binding patterns, compounds 5P and 5D were subjected to molecular docking against tubulin (Protein Data Bank ID: ISA0). The results showed that compounds revealed significant interactions and were well occupied inside the cavity of tubulin. The compounds 5D and 5P may serve as new leads in drug development against cancer.

Abstract
BACKGROUND Renal cell carcinoma (RCC) is a diverse collection of malignancies with varying histological characteristics, molecular changes, prognosis, and therapeutic response. Tivozanib was first approved in March 2021 by USFDA with the brand name Fotivda. Tivozanib hydrochloride monohydrate is an oral medication that is used to treat relapsed or refractory renal cell carcinoma. OBJECTIVE In this review, we explain renal cell carcinoma and its different types of treatment by the anti-renal carcinoma drugs. METHODS A comprehensive literature search was conducted in the relevant databases, like ScienceDirect, PubMed, ResearchGate, and Google Scholar, to identify the studies. CONCLUSION Tivozanib is an oral VEGFR-1, VEGFR-2, and VEGFR-3 tyrosine kinase inhibitor that is extremely selective and powerful. It has much less affinity for other receptor tyrosine kinases than multi-targeted TKIs now in clinical use. Because of its long half-life in circulation, it may be able to block VEGFRs more consistently. Doserelated controllable hypertension is its most commonly seen drug-related side event. Fatigue, hoarseness, and diarrhea, which are all common side effects, are not dose-related. Because of its target specificity, tivozanib can work well with other medications that have low side effects. Blocking both the VEGF and mTOR signaling pathways at the same time provides the benefit of synergistic antitumor efficacy while also preventing treatment resistance. Thus, overall we can say that the drug tivozanib is suitable for treatment in patients with renal cell carcinoma and can be investigated in multi-center clinical trials.

Abstract
Introduction:
Throughout the years, the disruption caused by COVID-19 continues to pose an excess of challenges for the pharmaceutical industry. Throughout the entire year, questions were raised that does COVID-19 have a negative impact on new drug approvals. However, the answer to those questions was a ‘big no’.
Methodology:
We propose a compilation and analysis of around 100 medications, including small new molecular entities (NMEs), approved by the US Food and Drug Administration for the years 2020 and 2021. Novel drug discovery is crucial for pharmaceutical research and development as well as patient care. The only possible way to achieve this crucial goal is to repurpose current medications that may have anticipated effects as possible candidates. The availability of new drugs and biological products often means new treatment options for patients and advances in health care
Results:
Around 40% of the drugs were approved for various types of cancers. Other major therapeutic areas that were focused on were neurological products (around 17%), infectious diseases (13-15%), and cardiovascular disorders (7-8%). Various new products were approved for rare diseases (58-60%). This study aimed to discover a pattern in FDA medicine approvals during the last two decades.
Conclusion:
This data shows that anticancer medicines and biologics are receiving increased attention in research. With a bigger number of biologically derived medications being produced, the price could rise much higher. FDA should embrace innovative techniques that will stimulate the industry to enhance research and development of novel compounds or medications that can deliver considerable improvements over existing ones. To put it briefly, FDA had to update our approach to regulation as a whole in order to effectively develop the types of technologies that are becoming available. Modernizing medical product review programmes is a part of this. These initiatives are part of the Medical Innovation Access Plan.

Abstract
Abstracts:
According to the WHO’s data for 2018, the global cancer burden was estimated to have risen to 18.1 million new cases and which alone accounted for 9.6 million deaths. Cancer is a group of diseases known as tumors that often spreads throughout the body, and may cause harm to multiple organs in the body. The global pharmaceutical spending is around 19% of the R&D cost annually to discover new and potent therapeutic agents. The major problems associated with currently available anticancer drugs are drug resistance and their side effects. They are the most widely explored groups of drugs either using instrumental or bioanalytical methods. In this review, we have compiled and reviewed the analytical and bio-analytical methods of some anticancer drugs developed by different authors. The review also briefly discusses the broad categories of cytotoxic drugs and targeted-based anticancer drugs. The analytical and bioanalytical methods of cytotoxic drugs such as alkylating agents, antimetabolites, hormones, and targeted-based drugs reported earlier and in recent research, articles are discussed in detail. These analytical methods are prerequisites for both the pharmaceutical industry and academics for their impurities profiling and qualitative as well as quantitative estimation. The accuracy, precision, LOD, and LOQ studies by UV-HPLC, LC-MS, and fluorometry HPLC are discussed. Some of the advanced methods developed, in the case of ifosfamide using Au/Pd@rGO@p(L-Cys) and the production of vincristine by endophytic fungi, are also included. This will further embolden the efforts of different researchers working in this field and ease the challenges they face through the analytical development of these drugs.

Abstract
INTRODUCTION It is currently unknown which method of cystic duct closure is most effective at reducing the risk of bile leak after laparoscopic cholecystectomy. The aims of this work were to determine the most common closure methods used in the UK and review available evidence on which method has the lowest risk of bile leak. METHODS We conducted an online survey through the Association of Upper Gastrointestinal Surgeons (AUGIS). We also undertook a systematic review using PubMed, EMBASE, MEDLINE and the Cochrane Library for studies that compared different methods for cystic duct occlusion and reported postoperative bile leak. FINDINGS There was significant variation in practice between consultant surgeons. For routine laparoscopic cholecystectomy metal clips were used most (64%) followed by locking polymer clips (33%) and suture ties (3%). In cases of a dilated cystic duct, preferences were locking polymer clips (60%), suture ties (30%) and metal clips (5%). We included six studies in our review with a total of 8,011 patients. Metal clips were associated with an increased odds of bile leak compared with locking polymer clips (OR 5.66, 95% CI 1.13-28.41, p=0.04) or suture ties (OR 4.17, 95% CI 0.72-24.31, p=0.12). Most studies were retrospective, unlikely to be adequately powered, and vulnerable to selection bias. CONCLUSIONS Limited available evidence suggests that metal clips have the highest risk of bile leak, but results are not strong enough to recommend a change in current clinical practice. A trial is now required to determine the best method of cystic duct closure.

Abstract
Breast microcalcifications are an important primary radiological indicator of breast cancer. However, microcalcification classification and diagnosis may be still challenging for radiologists due to limitations of the standard 2D mammography technique, including spatial and contrast resolution. In this study, we propose an approach to improve the detection of microcalcifications in propagation-based phase-contrast X-ray computed tomography of breast tissues. Five fresh mastectomies containing microcalcifications were scanned at different X-ray energies and radiation doses using synchrotron radiation. Both bright-field (i.e. conventional phase-retrieved images) and dark-field images were extracted from the same data sets using different image processing methods. A quantitative analysis was performed in terms of visibility and contrast-to-noise ratio of microcalcifications. The results show that while the signal-to-noise and the contrast-to-noise ratios are lower, the visibility of the microcalcifications is more than two times higher in the dark-field images compared to the bright-field images. Dark-field images have also provided more accurate information about the size and shape of the microcalcifications.

Abstract
Abstract:
Food preservatives are used to keep bacteria, moulds, fungus, and yeast from spoiling food. Food additives are subject to strict rules (particularly in the European Union - EU), which consider the food to which they can be applied, maximum permissible quantities, chemical characterization, and purity. Sorbic acid, mainly potassium sorbate, is primarily utilised in a variety of commercially available foods. Various analytical strategies for an asynchronous and simultaneous estimation of potassium sorbate have been reported along with other preservatives in marketed formulations or food products. The Square-wave voltammetry using a cathodically prepared boron-doped diamond electrode, quick UHPLC–fluorescent method, UV spectrophotometry, UHPLC-UV analysis, RP-HPLC, and mass spectrometry are some of the analytical techniques used. We have compiled various analytical methods to detect potassium sorbate with various other preservatives simultaneously or alone in marketed formulation. The authors feel that the studies summarised in this report will allow readers to choose the most acceptable and appropriate method for analysing this preservative.

Abstract
Depression is one of the major disorders of the central nervous system worldwide and causes disability and functional impairment. According to the World Health Organization, around 265 million people worldwide are affected by depression. Currently marketed antidepressant drugs take weeks or even months to show anticipated clinical efficacy but remain ineffective in treating suicidal thoughts and cognitive impairment. Due to the multifactorial complexity of the disease, single-target drugs do not always produce satisfactory results and lack the desired level of therapeutic efficacy. Recent literature reports have revealed improved therapeutic potential of multi-target directed ligands due to their synergistic potency and better safety. Medicinal chemists have gone to great extents to design multitarget ligands by generating structural hybrids of different key pharmacophores with improved binding affinities and potency towards different receptors or enzymes. This article has compiled the design strategies of recently published multi-target directed ligands as antidepressant agents. Their biological evaluation, structural-activity relationships, mechanistic and in silico studies have also been described. This article will prove to be highly useful for the researchers to design and develop multi-target ligands as antidepressants with high potency and therapeutic efficacy.

Abstract
Alzheimer's disease (AD), a multifactorial complex neural disorder, is categorized with progressive memory loss and cognitive impairment as main clinical features. The multitarget directed ligand (MTDL) strategy is explored for the treatment of multifactorial diseases such as cancer and AD. Herein, we report the synthesis and screening of 24 N-propargyl-substituted diphenylpyrimidine derivatives as MTDLs against acetylcholine/butyrylcholine esterases and monoamine oxidase enzymes. In this series, VP1 showed the most potent MAO-B inhibitory activity with an IC50 value of 0.04 ± 0.002 μM. VP15 with an IC50 value of 0.04 ± 0.003 μM and a selectivity index of 626 (over BuChE) displayed the most potent AChE inhibitory activity in this series. In the reactive oxygen species (ROS) inhibition studies, VP1 reduced intercellular ROS levels in SH-SY5Y cells by 36%. This series of compounds also exhibited potent neuroprotective potential against 6-hydroxydopamine-induced neuronal damage in SH-SY5Y cells with up to 90% recovery. In the in vivo studies in the rats, the hydrochloride salt of VP15 was orally administered and found to cross the blood-brain barrier and reach the target site. VP15·HCl significantly attenuated the spatial memory impairment and improved the cognitive deficits in the mice. This series of compounds were found to be irreversible inhibitors and showed no cytotoxicity against neuronal cells. In in silico studies, the compounds attained thermodynamically stable orientation with complete occupancy at the active site of the receptors. Thus, N-propargyl-substituted diphenylpyrimidines displayed drug-like characteristics and have the potential to be developed as MTDLs for the effective treatment of AD.

Abstract
Chlorpyrifos (CP) and its highly electrophilic intermediates are principal toxic metabolites. The active form of CP i.e. chlorpyrifos oxon (CP-oxon) is responsible for both the insecticidal activity and is also of greater risk when present in the atmosphere. Thus, the combined effects of both CP, CP-oxan, and other metabolites enhance our understanding of the safety and risk of the insecticide CP. They cause major toxicities such as AChE inhibition, oxidative stress, and endocrine disruption. Further, it can have adverse hematological, musculoskeletal, renal, ocular, and dermal effects. Excessive use of this compound results in poisoning and potentially kills a non-target species upon exposure including humans. Several examples of reactive metabolites toxicities on plants, aquatic life, and soil are presented herein. The review covers the general overview on reactive metabolites of CP, chemistry and their mechanism through toxic effects on humans as well as on the environment. Considerable progress has been made in the replacement or alternative to CP. The different strategies including antidote mechanisms for the prevention and treatment of CP poisoning are discussed in this review. The approach analyses also the active metabolites for the pesticide activity and thus it becomes more important to know the pesticide and toxicity dose of CP as much as possible.
