Abstract
BACKGROUND Altered T-cell repertoire with an aberrant T-cell activation and imbalance of the Th17/Treg cells has been reported in acquired aplastic anemia (aAA). miRNAs are well known to orchestrate T-cell activation and differentiation, however, their role in aAA is poorly characterized. The study aimed at identifying the profile of miRNAs likely to be involved in T-cell activation and the Th17/Treg-cell imbalance in aAA, to explore newer therapeutic targets. METHODS Five milliliters peripheral blood samples from 30 patients of aAA and 15 healthy controls were subjected to flow cytometry for evaluating Th17- and Treg-cell subsets. The differential expression of 7 selected miRNAs viz; hsa-miR-126-3p, miR-146b-5p, miR-155-5p, miR-16, miR-17, miR-326, and miR-181c was evaluated in the PB-MNCs. Expression analysis of the miRNAs was performed using qRT-PCR and fold change was calculated by 2-ΔΔCt method. The alterations in the target genes of deregulated miRNAs were assessed by qRT-PCR. The targets studied included various transcription factors, cytokines, and downstream proteins. RESULTS The absolute CD3+ lymphocytes were significantly elevated in the PB of aAA patients when compared with healthy controls (p < 0.0035), however, the CD4:CD8 ratio was unperturbed. Th17: Treg-cell ratio was altered in aAA patients (9.1 vs. 3.7%, p value <0.05), which correlated positively with disease severity and the PNH positive aAA. Across all severities of aAA, altered expression of the 07 miRNAs was noted in comparison to controls; upregulation of miR-155 (FC-2.174, p-value-0.0001), miR-146 (FC-2.006, p-value-0.0001), and miR-17 (FC-3.1, p-value-0.0001), and downregulation of miR-126 (FC-0.329, p-value-0.0001), miR-181c (FC-0.317, p-value-0.0001), miR-16 (FC-0.348, p-value-0.0001), and miR-326 (FC-0.334, p-value-0.0001). Target study for these miRNAs revealed an increased expression of transcription factors responsible for Th1 and Th17 differentiation (T-bet, RORϒt, IL-17, IL-6, and IFN-ϒ), T-cell activation (NFκB, MYC, and PIK3R2), downregulation of FOX-P3, and other regulatory downstream molecules like SHIP-1, ETS-1, IRAK-1, TRAF-6, and PTEN. CONCLUSION The study for the first time highlights the plausible role of different miRNAs in deregulating the Th17/Treg-cell imbalance in aAA, and comprehensively suggest the role of altered NF-kB and mTOR pathways in aAA. The axis may be actively explored for development of newer therapeutic targets in aAA.

Abstract
This study was conducted to evaluate the prebiotic effect of xylo-oligosaccharide (XOS) supplemented in a corn-soybean meal (SBM) based conventional diet on growth performance, intestinal histomorphology, and quantification of specific bacteria in the ceca of broilers. A total of 240 d of hatch Cobb 500 male broiler chicks were randomly assigned to 4 dietary treatments (corn-SBM-based control diet) containing 0, 0.05, 0.1, and 0.2% XOS. The broilers were raised for 21 d in 6 replicate cages, each containing 10 birds. Growth performance parameters were obtained weekly. Additionally, small intestinal tissues were collected to evaluate histomorphometry and whole ceca were collected to quantify bacterial populations on D21. The results showed that inclusion of XOS has similar body weight (BW), body weight gain (BWG), feed intake (FI), and feed conversion ratio (FCR) as the control group during the 21-day study. The results further indicate a tendency for the jejunum villus to crypt ratio (VH:CD) to increase in birds given 0.05 and 0.2% XOS (P = 0.08). Cecal bacteria quantification showed a linear increase in Bifidobacterium with increasing XOS levels (P < 0.0001) and a decrease Clostridium perfringens levels compared to birds fed the control diet (P < 0.0001). However, there were no differences in the total counts of Lactobacillus and E. coli. Together these results showed that while there were no differences in growth parameters up to 21 d, the histomorphology findings and the increase in Bifidobacterium, along with the reduction in C. perfringens observed in the XOS groups, suggest a beneficial impact of XOS inclusion on gut health. Further research with longer feeding periods and higher XOS levels should be conducted to explore potential positive effects on both growth and gut health parameters.

Abstract
Intracellular microorganisms, like viruses, bacteria, and fungi, pose challenges in detection due to their non-culturable forms. Transcriptomic analysis at cellular level enables exploration of distributions and the impact of these microorganisms on host cells, a domain that remains underexplored because of methodological limitations. Single-cell technology shows promise in addressing this by capturing polyadenine-tailed transcripts, because recent studies confirmed polyadenylation in microbial transcriptomes. We utilized single-cell RNA-seq from PBMCs to probe intracellular microbes in healthy, SARS-CoV-2-positive, and recovered individuals. Among 76 bacterial species detected, 16 showed significant abundance differences. Buchnera aphidicola, Streptomyces clavuligerus, and Ehrlichia canis emerged significantly in memory-B, Naïve-T, and Treg cells. Staphylococcus aureus, Mycoplasma mycoides, Leptospira interrogans, and others displayed elevated levels in SARS-CoV-2-positive patients, suggesting possible disease association. This highlights the strength of single-cell technology in revealing potential microorganism's cell-specific functions. Further research is essential for functional understanding of their cell-specific abundance across physiological states.

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
Malaria and concurrent bacteraemia cases have been reported globally, mostly in association with Plasmodium falciparum malaria. In comparison, concurrent bacteraemia with Plasmodium vivax infected patients is reported rarely. However, considering unavailability of blood culture testing and widespread community and empirical antibiotic usage in low- and middle-income countries (LMICs), the frequency of bacteraemia and P. vivax co-infection may be much higher. We reported two cases of Staphylococcus aureus bacteraemia with P. vivax malaria infection. Both patients presented with high grade fever and chills with unremarkable systemic examination. Liver enzymes were raised along with inflammatory markers. Simultaneous diagnosis of methicillin sensitive S. aureus bacteraemia was done using automated blood culture, automated identification and sensitivity testing system. P. vivax malaria was confirmed with microscopy, antigen detection test and molecular test. Patients recovered uneventfully with antimalarial drugs and antibiotics.

Abstract
The milk, meat, skins, and draft power of domestic water buffalo (Bubalus bubalis) provide substantial contributions to the global agricultural economy. The world's water buffalo population is primarily found in Asia, and the buffalo supports more people per capita than any other livestock species. For evaluating the workflow, output rate, and completeness of transcriptome assemblies within and between reference-free (RF) de novo transcriptome and reference-based (RB) datasets, abundant bioinformatics studies have been carried out to date. However, comprehensive documentation of the degree of consistency and variability of the data produced by comparing gene expression levels using these two separate techniques is lacking. In the present study, we assessed the variations in the number of differentially expressed genes (DEGs) attained with RF and RB approaches. In light of this, we conducted a study to identify, annotate, and analyze the genes associated with four economically important traits of buffalo, viz., milk volume, age at first calving, post-partum cyclicity, and feed conversion efficiency. A total of 14,201 and 279 DEGs were identified in RF and RB assemblies. Gene ontology (GO) terms associated with the identified genes were allocated to traits under study. Identified genes improve the knowledge of the underlying mechanism of trait expression in water buffalo which may support improved breeding plans for higher productivity. The empirical findings of this study using RNA-seq data-based assembly may improve the understanding of genetic diversity in relation to buffalo productivity and provide important contributions to answer biological issues regarding the transcriptome of non-model organisms.

Abstract
The objective of the study was to investigate the effects of a dacitic tuff breccia (DTB) on Eimeria-infected broilers. A total of 600 one-day-old Cobb 500 male chickens were randomly assigned to 5 treatments with 10 replicates of 12 birds. Treatments were: an unchallenged control (UC), a challenged (CC) control (0% DTB), and 3 challenged groups with 0.125, 0.25, or 0.5% DTB. At d 14, birds in the CC and DTB groups were orally gavaged with mixed Eimeria spp., while the UC received water. Growth performance was evaluated during prechallenge, challenge, and postchallenge periods (0-14 d; 14-20 d; and 20-26 d, respectively). Gastrointestinal permeability was measured at 5 days postinfection (dpi). Intestinal histology and nutrient digestibility of dry matter (DM), crude protein (CP), and ileal digestible energy (IDE) were measured at 6 dpi. Liver activity of glutathione peroxidase (GSH-Px) was determined at 6 dpi, and concentrations of reduced (GSH) and oxidized glutathione (GSSG) were analyzed at 6 and 12 dpi. Data were analyzed using a linear mixed model analysis and Tukey's test (P ≤ 0.05). From 0 to 14 d, similar average daily gain (ADG) and average daily feed intake (ADFI, P > 0.05) were observed. Gain:feed ratio (GF) was higher in 0.125, 0.25, and 0.5% of DTB than the CC and UC (P < 0.001). From 14 to 20 d, the UC had the highest ADG, ADFI, and GF (P < 0.001). At 5 dpi, intestinal permeability was higher in the challenged groups than the UC. Additionally, the UC showed the highest apparent ileal digestibility of CP, whereas 0.125% DTB had higher CP digestibility than the CC and 0.5% DTB (P < 0.001). At 6 dpi, 0.125% DTB increased GSH-Px activity compared to the CC, 0.5% DTB, and UC (P < 0.001). At 12 dpi, 0.125% DTB showed increased GSH concentration compared to the CC, 0.25% DTB, and 0.5% DTB (P < 0.01). The mild coccidia infection negatively impacted growth performance, apparent ileal nutrient digestibility, intestinal histology, and gastrointestinal integrity in broilers. The use of 0.125% DTB exhibited potential in improving antioxidant responses, apparent ileal digestibility of CP, and growth performance.

Abstract
White mold commonly known as Sclerotinia sclerotiorum causes stem rot disease and has emerged as one of the major fungal pathogens of oilseed Brassica across the world. In the present study, consistently virulent S. sclerotiorum isolate "ESR-01" was sequenced and an assembly size of ~ 41 Mb with 328 scaffolds having N50 of 447,128 was obtained. Additionally, 27,450 single nucleotide polymorphisms (SNPs) were identified from 155 scaffolds against S. sclerotiorum 1980 isolate, with an average SNP density of ~ 1.5 per kb genome. 667 repetitive elements were identified and approximately comprised 7% of the total annotated genes. The DDE_1 with 454 in numbers was found to be the most abundant and accounts for 68% of the total predicted repetitive elements. In total, 3844 simple sequence repeats are identified in the 328 scaffolds. A total of 9469 protein-coding genes were predicted from the whole genome assembly with an average gene length of 1587 bp and their distribution as 230.95 genes per Mb in the genome. Out of 9469 predicted protein-coding genes, 529 genes were observed encoding the CAZymes (Carbohydrate-Active enzymes) capable of degradation of the complex polysaccharides. Glycosyltransferase (GT) families were most abundant (49.71%) among the predicted CAZymes and GT2 (23%), GT4 (20%), and glycoside hydrolase (GH) 23% with GH18 (11%) were the prominent cell wall degrading enzyme families in the ESR-01 secretome. Besides this, 156 genes essential for the pathogen-host interactions were also identified. The effector analysis in the whole genome proteomics dataset revealed a total of 57 effector candidates (ECs) and 27 of them were having their analogs whereas the remaining 30 were novel ones. Eleven selected ECs were validated experimentally by analyzing the expression profile of the ESR-01 isolate of S. sclerotiorum. Together, the present investigation offers a better understanding of the S. sclerotiorum genome, secretome, and its effector repertoire which will help in refining the present knowledge on S. sclerotiorum-Brassica interactions and necrotrophic lifestyle of the phytopathogen in general.

Abstract
SARS-CoV-2 virus pathogenicity and transmissibility are correlated with the mutations acquired over time, giving rise to variants of concern (VOCs). Mutations can significantly influence the genetic make-up of the virus. Herein, we analyzed the SARS-CoV-2 genomes and sub-genomic nucleotide composition in relation to the mutation rate. Nucleotide percentage distributions of 1397 in-house-sequenced SARS-CoV-2 genomes were enumerated, and comparative analyses (i) within the VOCs and of (ii) recovered and mortality patients were performed. Fisher's test was carried out to highlight the significant mutations, followed by RNA secondary structure prediction and protein modeling for their functional impacts. Subsequently, a uniform dinucleotide composition of AT and GC was found across study cohorts. Notably, the N gene was observed to have a high GC percentage coupled with a relatively higher mutation rate. Functional analysis demonstrated the N gene mutations, C29144T and G29332T, to induce structural changes at the RNA level. Protein secondary structure prediction with N gene missense mutations revealed a differential composition of alpha helices, beta sheets, and coils, whereas the tertiary structure displayed no significant changes. Additionally, the N gene CTD region displayed no mutations. The analysis highlighted the importance of N protein in viral evolution with CTD as a possible target for antiviral drugs.

Abstract
BACKGROUND The study was done to evaluate the feasibility, safety and outcomes of a one-stop thyroid clinic (OSTC) in a low- and middle-income country (LMIC) setting. METHODS This was a prospective non-randomised case control study consisting of patients with thyroid nodules evaluated and managed at a tertiary referral centre in an LMIC between February 2019 and January 2020. Patients were divided into two groups based on the kind of preoperative evaluation protocol: OSTC group (n = 118) - OSTC protocol, and control group (CG, n = 108) - routine protocol. RESULTS Baseline clinical characteristics of the two groups including median age (p = 0.13) and gender distribution (p = 0.76) were comparable. The majority of patients in both groups belonged to a low-income group (46.6% vs 47.3%; p = 0.91), followed by a middle-income group (35.6% vs 30.5%; p = 0.41). The median number of outpatient department visits (1 vs 3 days; p = < 0.001), waiting time for neck ultrasonography (1 vs 3 days; p = < 0.0001), fine needle aspiration cytology (1 vs 2 days; p = < 0.0001), and out of pocket expenditure (INR 3 965 vs 6 624; p = < 0.001) was significantly less in the OSTC group compared to the CG. Patients in the OSTC group reported better satisfaction levels (p = < 0.0001). Accuracy of diagnosis did not differ between the two groups (p = 0.14). CONCLUSION OSTC practice is feasible, provides comparative clinical outcomes and seems cost effective in an LMIC. This protocol can be adopted as a routine practice in any health system.

Type of funding sources: None.
Background
India has among the world's highest burden of cardiovascular disease, potentially contributed by myocardial infarction. Despite growing trouble, there are no known post-discharge programs & randomized trials reporting health status outcomes & quality of life among post-myocardial infarction patients. Cardiac rehabilitation programs reduce mortality, therefore, it is crucial to understand the local burden of the disease, common challenges, public perceptions, develop timely & effective interventional programs.
Purpose
This study aimed to evaluate the effect of a nurse-led lifestyle modification follow-up program on health outcomes & quality of life among post-myocardial infarction patients.
Methods
A two-arm randomized controlled trial was adopted & 104 post-myocardial infarction patients were recruited from August to December 2021. An equal number of participants were randomly assigned to intervention & control group by random number table generator. The control group patients received routine care, while the intervention group was provided routine care along with a nurse-led lifestyle modification follow-up program(health education, educational booklet, & telephone follow- up). A low-cost intervention based on information-motivation-behavioural skill model was developed. It was designed according to the needs of patients to know their risk factors, help patients establish a knowledge base, & adapt to the post-illness lifestyle changes. Data were assessed & compared by using the demographic datasheet, health outcomes datasheet, & MacNew heart disease quality of life questionnaire. All evaluations were conducted at baseline after 12 weeks post-discharge, by face-to-face interview & biophysiological measurements.
Results
The nurse-led lifestyle modification follow-up program was convenient for clinical application. The intervention group showed a appreciable improvement in low density lipoprotein(p=0.045), systolic blood pressure(p=0.009), diastolic blood pressure(p=0.044), body mass index(p=0.043), and NT ProBNP(p=0.007). The program effectively improved the lifestyle behaviours thereby considerably improving the quality of life in all the subscales-physical, emotional & social (p<0.001) after 12 weeks of discharge.
Conclusion
In the Indian context, it is a novel & extensive approach to improve access to health care and emphasizes post-discharge self-management. The greatest benefit of this program was allowing the intervention group participants to consult with us immediately. Since lifestyles vary among different individuals, we considered individuality when providing education & involving them in implementation of an intervention to enhance their confidence & ultimately achieve optimal health outcomes & quality of life. The findings of this study are important for health care professionals caring for post-myocardial infarction patients & direct incorporation of such programs into routine practice to reduce morbidity & mortality.

Abstract
Methotrexate leading to hypercalcaemia is a rarely reported adverse event. We present three elderly patients with inflammatory arthritis who developed hypercalcemia probably due to methotrexate-induced granulomatous pneumonitis. All patients presented with worsening non-productive cough with dyspnea, nausea, loss of appetite, and confusion. Their clinical and radiologic features were consistent with methotrexate-induced pneumonitis. On evaluation, all patients concurrently had hypercalcemia with normal 25OH D3, and low PTH with markedly elevated levels of 1,25OH D3 seen in two patients. In all three patients, hypercalcemia and pneumonia responded to hydration, corticosteroids, and methotrexate withdrawal. There was no relapse of symptoms on long term follow-up. In these three patients with inflammatory arthritis, methotrexate-induced pneumonitis led to symptomatic hypercalcemia. Unless hypercalcemia is looked for and treated in this setting, the morbidity can be high.

Abstract
BackgroundCoronavirus Disease (covid 19) negatively impacted psychosocial health, health care accessibility and exercise regimen but problem’s scope and potential solutions remain elusive. We conducted a patient based online survey to understand these impacts and discussed potential solutions.ObjectivesAssess impact of Covid 19 on rheumatological disease status, accessibility to health care, patient anxiety and behavior and continuation of physical activity during pandemic.MethodsGoogle form (18-question) based questionnaire was sent via SMS/WhatsApp in Aug 2020, at height of first pandemic and responses were collected over next month.ResultsOnly 339 /2700 patients (12.5 %) responded to the survey. Other authors (1)(2) have observed a similar low response rate to online surveys. We recognise questionnaires with fewer questions tend to generate more responses, which should be considered critical in constructing future health-related surveys. Patients’ global assessment of their disease score was 7/10, with 0 representing the worst disease status and10 representing best disease status, also 1/3 patients not felt need for rheumatological consultation during six months (March 2020- Aug 2020) of lockdown. These may imply adequate rheumatic disease control over long periods and during subsequent waves of pandemic, rheumatology patients can be shielded by avoiding non-urgent hospital follow up visits. Significant number of patients (20%) were unable to contact their rheumatologist, implying a significant impact of covid 19 and lockdown on rheumatology care, as suggested by other authors (1). As expected, there was switch to tele consultancy mode of communication, with 22 per cent of patients already using it within 3 months of its introduction, which appears to be a good indicator of future adaptability and feasibility of teleconsultation. Identifying specific profile of patients during physical consultation who can be easily managed via teleconsultation, may reduce unnecessary hospital visits while also improving healthcare delivery. 1/3 of our patients had anxiety about disease flare, and 41 %were concerned about increased risk of covid 19 infection as they were on immunosuppressive medications as noted by other authors (3). Improving access to health care and increasing public awareness could help alleviate this anxiety. Reaching out to isolated rheumatology patients through SMS / educational video may improve the sense of health security. Contrary to our expectations, overall medication adherence was reasonable, likely due to be management of supply chains by local authorities .15% completely stopped exercising and 25% reduced their exercise regimen by 50%. Shifting to home-based exercise, educational videos on physical therapy and online teleconsultation with physiotherapists could overall have positive impact.ConclusionCovid 19 has significantly impacted rheumatological patients in terms of increased anxiety, decreased healthcare accessibility and decreased exercise and physical activities. Modifications in teleconsultation methodology are needed in the future. Patients’ anxiety can be alleviated by educating them through digital and social media platforms and enrolling them in online patient support groups.References[1]Ganapati A, Padiyar S, Nair A, et al.

Abstract
Wnt-β-catenin signaling plays a key role in orthodontic tooth movement (OTM), a common clinical practice for malocclusion correction. However, its targeted periodontal ligament (PDL) progenitor cells remain largely unclear. In this study, we first showed a synchronized increase in Wnt-β-catenin levels and Axin2+ PDL progenitor cell numbers during OTM using immunostaining of β-catenin in wild-type mice and X-gal staining in the Axin2-LacZ knock-in line. Next, we demonstrated time-dependent increases in Axin2+ PDL progenitors and their progeny cell numbers within PDL and alveolar bones during OTM using a one-time tamoxifen-induced Axin2 tracing line (Axin2CreERT2/+; R26RtdTomato/+). Coimmunostaining images displayed both early and late bone markers (such as RUNX2 and DMP1) in the Axin2Lin PDL cells. Conversely, ablation of Axin2+ PDL cells via one-time tamoxifen-induced diphtheria toxin subunit A (DTA) led to a drastic decrease in osteogenic activity (as reflected by alkaline phosphatase) in PDL and alveolar bone. There was also a decrease in new bone mass and a significant reduction in the mineral apposition rate on both the control side (to a moderate degree) and the OTM side (to a severe degree). Thus, we conclude that the Axin2+ PDL cells (the Wnt-targeted key cells) are highly sensitive to orthodontic tension force and play a critical role in OTM-induced PDL expansion and alveolar bone formation. Future drug development targeting the Axin2+ PDL progenitor cells may accelerate alveolar bone formation during orthodontic treatment.

Abstract
A total of six vegetables (S. tuberosum, D. carota, S. lycopersicum, A. esculentus, S. oleracea and B. juncea) were analysed for five heavy metals (As, Cd, Cr, Hg, and Pb) to evaluate the contamination load in vegetables collected from five cultivated and two market sites (n = 504) at Delhi, India. The irrigation water samples and soil samples (n = 180) were only collected from cultivated sites. The results showed that the concentration of heavy metals in soil and water samples were well below the permissible level except for Cd 0.001-0.013 µg g-1. Similarly, the concentration of Cd (>0.20 µg g-1) was detected higher in all investigated vegetables except for tomato. The evaluation index value was highest for spinach and lowest for tomato. The transfer factor values and metal pollution index was maximum in spinach and okra. Principal component analysis (PCA), Tukey's HSD (Honestly Significant Difference) test, and one-way and two-way ANOVA (Analysis of Variance) were also applied to statistically analyse the results.

Abstract
Introduction Agad Tantra being the unique branch that deals with toxicology and its management enlists several antitoxic drugs used for various poisonings. Ancient texts comprise the list of a wide range of traditional medicines, but they are not explored due to lack of incomprehension. Aims The review has been written with the aim to dig out the hidden knowledge of Vishaghna Dravyas (alexeterics) mentioned in Kaiydeva Nighantu. Materials and methods This Nighantu was written in the 15th century A. D. by Kaiydeva with the name "Pathya-Apathya-Vibodhaka" it comprising of total 514 Dravyas out of which 175 drugs possess Vishagna (anti-poisonous) property. Results These Vishaghna Dravyas (alexeterics) have been distributed based on various Vargas (classes) which is described as 121 belonging to Ausghada Varga (drug class) as single drugs and four as groups, total of 16 from Dhatu Varga (metal class) as single drugs and one as compound or as a group, 9 from Dhanya Varga (cereal class) as a single drug, 15 in Dravya Varga as single drugs, and 5 as compound or as a group. Two each in Kritana Varga and Vihara Varga and one in Mansa Varga as compound or as a group. Out of all the 175 Vishagna Dravayas (alexeterics), 18 Dravyas (substances) are specific indications in combating particular types of envenomation or poisoning conditions. Conclusion All the abovementioned drugs are screened for the purpose of revalidation to bring out their therapeutic utility.

Abstract
Abstract
Aim
This study aims to assess the impact of pre-operative factors on the length of stay in patients following total knee replacement at our institution.
Method
A total of 478 patients following total knee replacement between January 2017-Decemeber 2019 are included in this study. All patients underwent total knee replacement with a medial rotating total knee prosthesis (MRK; Matt Ortho UK).
Data for each patient was collated retrospectively and included the following: Patient demographics (age and sex), American Society of Anaesthesiology (ASA) score, pre-operative range of movement (ROM), Body Mass Index (BMI), and pre-operative haemoglobin. Each factor was then compared with the length of stay for all 478 patients. Statistical significance was sort for each pre-operative factor for both men and women.
Results
Our cohort of patients includes 291 females and 187 males. Patients ranged from 39 to 90 years with an average age of 68. The average BMI of the cohort was 31.3(18.6–56.56) and the average ASA grade was 2.
Preoperative hemoglobin and the Age of the patient at the time of surgery were the only two factors which had a statistically significant impact on the length of hospital stay (p<0.05). BMI, Pre- operative range of motion and ASA scores had no statistically significant effect on the length of hospital stay in our cohort.
Conclusions
Low pre-operative hemoglobin and increasing age have significant effects on length of stay after total knee replacement. The BMI, pre-operative range of movement and ASA scores do not influence the length of hospital stay.

Abstract
This study was performed to investigate the effect of feeding Brassica spp. including full-fat rapeseed, canola meal, and allyl isothiocyanate (AITC) to broiler chicken challenged with E. maxima. A total of 576 one-day old male broiler chicks were completely randomized to 8 treatments with 6 replicated cages and 12 birds per cage. The treatment diets consisted of nonchallenge control (NC, corn-SBM based diet), challenge control (CC), 10% rapeseed (10RS), 30% rapeseed (30RS), 20% canola (20CLM), 40% canola (40CLM), 500 ppm AITC (500AITC), and 1,000 ppm AITC (1000AITC). At d 14, all birds were challenged, except NC group, with a subclinical dose of E. maxima. Intestinal permeability was conducted on 5 d post-infection (dpi) and for oocyst shedding 5 to 6 dpi feces were pooled and collected. On 6 dpi, growth performance, lesion score, histomorphology, and gene expression were measured. The growth performance result showed that 10RS and 30RS groups had lower BW, BWG, FI, and higher FCR (P < 0.0001). During the challenge and overall periods, NC group had highest BW, BWG, and FI, and lowest FCR. The inclusion of canola meal showed lower performance during prechallenge period but was able to catch up BWG during challenge period. The AITC levels showed similar growth performance to CC group. Intestinal permeability for 20CLM, 40CLM, 500AITC and 1000AITC was similar to NC group, whereas CC, 10RS, and 30RS had higher permeability compared to NC (P < 0.0001). Oocyst shedding was significantly lower for 40CLM and NC, whereas all other treatments had higher oocyst shedding (P < 0.0001). All the challenged treatment groups had higher lesion score and microscore than NC (P < 0.0001). Histomorphology data showed that jejunum villus height (VH) for 1000AITC was similar to NC group, whereas CC group had the lowest VH (P = 0.01). The 30RS group had lower VH: crypt depth (CD) ratio in the jejunum and ileum. The gene expression at 6 dpi for claudin1, occludin, IL2, IL6, GLUT5, EAAT, BoAT, and LAT1 was significantly changed among the treatments. The results suggest that 30RS retards growth performance and deteriorate gut health during coccidiosis and should not be fed to chicken during the starter phase. Canola meal showed decline in growth prechallenge but maintained growth and intestinal health during the challenge period at 40% inclusion. AITC at 1,000 ppm showed similar growth as control group, but with improved gut health during the challenge period. Canola meal could be a good alternative to SBM especially during coccidiosis, whereas AITC needs to be tested vigorously in animal feeding regime.

Abstract
Poultry is the major sources of foodborne salmonellosis. Antibiotic resistance and a surge in zoonotic diseases warrant the use of natural alternatives. Glucosinolates (GLs) are naturally occurring antimicrobial compounds in rapeseed and canola. This study investigated the effect of feeding rapeseed, canola meal, and allyl isothiocyanate (AITC; Brassica secondary metabolites) on growth performance (GP), gut health, and the potential antimicrobial activity against nalidixic acid-resistant Salmonella Typhimurium (STNR) in chickens. A total of 640 one-day-old male Cobb 500 broilers were randomly allocated to 8 treatments with 8 replicated cages and 10 birds per cage. Dietary treatments were nonchallenge control (NC, corn-SBM based), challenge (Salmonella) control (CC), 10% rapeseed (10RS), 30% rapeseed (30RS), 20% canola meal (20CLM), 40% canola meal (40CLM), 500 ppm AITC (500AITC), and 1,500 ppm AITC (1500AITC). On d 1, all the birds except NC were orally challenged with STNR (7 log CFU/bird). The chickens were reared for 21 d, and their FI and BW were recorded weekly. Salmonella cecal colonization and fecal shedding were quantified, whereas organ translocation (OT) of STNR to the spleen, liver, and kidney was tested on 0, 3, 6, 13, and 20-d postchallenge (dpc). Data were subjected to one-way ANOVA, and the means were separated by Duncan's test, except mortality and OT data analyzed after transformation by square root of (n +1) (P < 0.05). Overall, feeding 30RS resulted in reduced BW (P = 0.003), BWG (P = 0.003), and FI (P = 0.001) compared to CC, 500AITC, and 1500AITC. Similarly, feeding 20CLM resulted in lower BW and BWG compared to CC (P < 0.05) and increased FCR compared to 1500AITC (P = 0.03). Feeding CC resulted in higher mortality compared to NC and 30RS (P = 0.03). Cecal colonization of STNR was reduced (P < 0.0001) for 30RS on 6 dpc and 500AITC on 6 and 13 dpc (P < 0.0001). Although no difference in gut permeability was observed 6 dpc (P > 0.05), OT of STNR population was the highest for CC in the spleen (P = 0.05). In the liver, 10RS showed reduced OT compared to 20CLM on 13 dpc (P = 0.03), whereas 30RS showed the lowest OT on 6 dpc in the kidney. Fecal shedding was lowest for 30RS on 6 dpc (P = 0.004). Histomorphology showed 30RS had the highest duodenum (P = 0.01) and jejunum (P = 0.02) villus height (VH) and VH to crypt depth (CD) ratio compared to the other treatments, whereas 1500AITC showed similar results to 30RS. Both 30RS and 1500AITC contained comparatively higher functional GL metabolites and were able to maintain gut health. Including higher levels of rapeseed or AITC in poultry feed can reduce Salmonella colonization in the feces and their translocation to other organs.

Abstract
The Education system in India underwent a major change due to the sudden lockdown announced by the Government in view of COVID – 19 pandemic. Both teachers and students had to shift to online mode in a very short time period. The present study analysis the positive and negative aspect of this online mode of education and measures adopted by teachers to maintain the flow of education along with attendance. The sur- vey was conducted at JSS Academy of Technical Education, Noida. More than 100 teachers and students participated in the survey conducted. Also experienced faculty came up with sug- gestions and ideas to improve the online mode of education in view of such pandemic situations. Two teachers who were also teaching kids at an NGO school running in the campus prem- ises shared their view on what efforts they took to let education reach the kids at the NGO as digital divide was the main prob- lem there. Such findings will help in designing a future teach- ing model to cope with pandemic situations and not let educa- tion suffer.

Abstract
Coronavirus disease-19 (COVID-19) pandemic is associated with high morbidity and mortality. COVID-19, which is caused by the Severe Acute Respiratory Syndrome Coronavirus-2 (SARS CoV-2), affects multiple organ systems through a myriad of mechanisms. Afflicted patients present with a vast constellation of symptoms, from asymptomatic disease to life-threatening complications. The most common manifestations pertain to mild pulmonary symptoms, which can progress to respiratory distress syndrome and venous thromboembolism. However, in patients with renal failure, life-threatening cardiac abnormalities can ensue. Various mechanisms such as viral entry through Angiotensin receptor (ACE) affecting multiple organs and thus releasing pro-inflammatory markers have been postulated. Nevertheless, the predictors of various presentations in the affected population remain elusive. An ameliorated understanding of the pathology and pathogenesis of the viral infection has led to the development of variable treatment options, with many more that are presently under trial. This review article discusses the pathogenesis of multiple organ involvement secondary to COVID-19 infection in infected patients. This review sheds light on the pathogenesis of multi-organ involvement secondary to COVID-19 infection. The predictors of various presentations in the affected population are not clear at present. A better understanding of the pathology and pathogenesis of the viral infection will be pivotal in the development of variable treatment options. Various proposed mechanisms such as viral entry through Angiotensin receptor (ACE) affecting multiple organs, releasing pro-inflammatory markers and cytokines inducing hypercoagulable state and cytokine storm syndrome have been postulated.

Abstract
BACKGROUND Recurrence of periampullary cancer after pancreatoduodenectomy is common. The aim of this study was to investigate patterns of recurrence, incidence, and factors associated with local and distant recurrences. METHODS This retrospective, single-centre study included consecutive patients with periampullary cancer who underwent resection with curative intent from January 2012 to January 2018. Survival, patterns of recurrence, and factors associated with recurrences were analysed. RESULTS Median overall survival (OS) and disease-free survival among 398 included patients was 58.4 and 49.5 months respectively. Twenty-three patients (5.8 per cent) developed isolated local recurrences (LR), 50 (12.6 per cent) developed LR along with distant metastasis (DM), and 103 (25.9 per cent) developed isolated DM. Median OS was 40.4 months for patients with isolated LR versus 23 months for those with DM (P < 0.001). Tumour subtype (distal common bile duct (CBD): odds ratio (OR) 6.18, 95 per cent c.i. 2.19 to 17.46) and node-positive status (OR 2.36, 1.26 to 4.43) were independently associated with higher rates of LR. The most common site for isolated LR was along the superior mesenteric artery (12 of 23 patients). Tumour subtype (distal CBD: OR 2.86, 1.09 to 7.52), nodal positivity (OR 2.46, 1.53 to 3.94), and presence of perineural invasion (OR 1.80, 1.02 to 3.18) were independently associated with DM. CONCLUSION Isolated LR is associated with better survival than DM and occurs most commonly along the superior mesenteric artery.

represents eleven species of earthworms of the family Moniligastridae: Drawida brunnea Stephenson, Drawida circumpapillata Aiyer, Drawida ghatensis Michaelsen, Drawida impertusa Stephenson, Drawida nilamburensis (Bourne), Drawida robusta (Bourne), Drawida scandens Rao, Drawida travancorense Michaelsen, Moniligaster aiyeri Gates, Moniligaster deshayesi Perrier, and Moniligaster gravelyi (Stephenson). In the phylogenetic analysis all the species were recovered in both neighbour–joining (NJ) and maximum likelihood (ML) trees with high clade support. The average K2P distance within and between species was 1.2 % and 22 %, whereas the clear barcode gap of 2–5 % was suggested by barcode gap analysis (BGA) of studied species, reflecting the accuracy of characterization. The study presents the first step in the molecular characterization of the native earthworm family Moniligastridae of India.

Abstract
Lymphatic filariasis causes permanent and long-term disability worldwide. Lack of potent adulticidal drugs, the emergence of drug resistance, and the nonavailability of effective vaccines are the major drawbacks toward LF elimination. However, immunomodulatory proteins present in the parasite secretome are capable of providing good protection against LF and thus offer hope in designing new vaccines against LF. Here, we evaluated the immunogenicity and protective efficacy of B. malayi calreticulin protein (BmCRT) using in vitro and in vivo approaches. Stimulation with recombinant BmCRT (rBmCRT) significantly upregulated Th1 cytokine production in mouse splenocytes, mesenteric lymph nodes (mLNs), and splenic and peritoneal macrophages (PMΦs). Heightened NO release, ROS generation, increased lymphocyte proliferation, and increased antigen uptake were also observed after rBmCRT exposure. Mice immunized with rBmCRT responded with increased Th1 and Th2 cytokine secretion and exhibited highly elevated titers of anti-BmCRT specific IgG at day 14 and day 28 postimmunization while splenocytes and mLNs from immunized mice showed a robust recall response on restimulation with rBmCRT. Infective larvae (L3) challenge and protection studies undertaken in Mastomys coucha, a permissive model for LF, showed that rBmCRT-immunized animals mounted a robust humoral immune response as evident by elevated levels of total IgG, IgG1, IgG2a, IgG2b, and IgG3 in their serum even 150 days after L3 challenge, which led to significantly reduced microfilariae and worm burden in infected animals. BmCRT is highly immunogenic and generates robust antiparasitic immunity in immunized animals and should therefore be explored further as a putative vaccine candidate against LF.

Abstract
The current advances and innovations in sensor technologies attributed to Industry 4.0 serve as the backbone for the inclusive growth of industry and ramping up the economy of any country. Industry 4.0 was basically conceptualized by introducing the Internet of Things (IoT) and Information and Communication technologies (ICT) that serve as an interface between digital and physical world through the fusion of smart sensors. The role of smart sensors and IoT-enabled industrial infrastructure is pivotal for adapting to the advanced technologies based on fusion of smart sensors. Digital meteorological traceability and uses of intelligent sensors, instrumentation and machinery in Industry 4.0, Smart Cities, Digital India and AtmaNirbhar Bharat missions of the government of India, are not only highly important but also in huge demand, which is going to increase manifolds in the years to come. The present paper is an attempt to provide a terse review and perspectives related to the advanced technological developments in this field and the challenges therein.

Abstract
Visceral leishmaniasis (VL) is a potentially fatal parasitic disease causing high morbidity and mortality in developing countries. Vaccination is considered the most effective and powerful tool for blocking transmission and control of diseases. However, no vaccine is available so far in the market for humans. In the present study, we characterized the hypothetical protein LDBPK_252400 of Leishmania donovani (LdHyP) and explored its prophylactic behavior as a potential vaccine candidate against VL. We found reduced hepato-splenomegaly along with more than 50% parasite reduction in spleen and liver after vaccination in mice. Protection in vaccinated mice after the antigen challenge correlated with the stimulation of antigen specific IFN-γ expressing CD4+T cell (~4.6 fold) and CD8+T cells (~2.1 fold) in vaccinated mice in compared to infected mice, even after 2-3 months of immunization. Importantly, antigen-mediated humoral immunity correlated with high antigen specific IgG2/IgG1 responses in vaccinated mice. In vitro re-stimulation of splenocytes with LdHyP enhances the expression of TNF-α, IFN-γ, IL-12 and IL-10 cytokines along with lower IL-4 cytokine and IL-10/IFN-γ ratio in vaccinated mice. Importantly, we observed ~3.5 fold high NO production through activated macrophages validates antigen mediated cellular immunity induction, which is critical in controlling infection progression. These findings suggest that immunization with LdHyP mount a very robust immunity (from IL-10 towards TFN-γ mediated responses) against L. donovani infection and could be explored further as a putative vaccine candidate against VL.

Abstract
Visceral Leishmaniasis (VL) is an insect-borne neglected disease caused by the protozoan parasite Leishmania donovani. In the absence of a commercial vaccine against VL, chemotherapy is currently the only option used for the treatment of VL. Vaccination has been considered as the most effective and powerful tool for complete eradication and control of infectious diseases. In this study, we aimed to design a peptide-based vaccine against L. donovani using immuno-bioinformatic tools. We identified 6 HTL, 18 CTL, and 25 B-cell epitopes from three hypothetical membrane proteins of L. donovani. All these epitopes were used to make a vaccine construct along with linkers. An adjuvant was also added at the N-terminal to enhance its immunogenicity. After that, we checked the quality of this vaccine construct and found that it is nontoxic, nonallergic, and thermally stable. A 3D structure of the vaccine construct was also generated by homology modeling to evaluate its interaction with innate immune receptors (TLR). Molecular docking was performed, which confirmed its binding with a toll-like receptor-2 (TLR-2). The stability of vaccine-TLR-2 complex and underlying interactions were evaluated using molecular dynamic simulation. Lastly, we carried out in silico cloning to check the expression of the final designed vaccine. The designed vaccine construct needs further experimental and clinical investigations to develop it as a safe and effective vaccine against VL infection.

Abstract
Coronavirus Disease 2019 (COVID-19) is a rapidly progressing global pandemic that may present with a variety of cardiac manifestations including, but not limited to, myocardial injury, myocardial infarction, arrhythmias, heart failure, cardiomyopathy, shock, thromboembolism, and cardiac arrest. These cardiovascular effects are worse in patients who have pre-existing cardiac conditions such as coronary artery disease, hypertension, diabetes mellitus, and coagulation abnormalities. Other predisposing risk factors include advanced age, immunocompromised state, and underlying systemic inflammatory conditions. Here we review the cellular pathophysiology, clinical manifestations and treatment modalities of the cardiac manifestations seen in patients with COVID-19.

Abstract
Background Spontaneous pneumothorax is not an uncommon medical emergency in pulmonary practice. Related data are not available in our setting. In emergency departments, clinical presentation is often confused with other cardiopulmonary problems. Follow up outcome is important for better patient care. Objective To study clinical profile and outcome after non surgical intervention in a tertiary care center. Method This was a prospective observational study carried out in Nobel Medical College, Biratnagar over last 3 years. We enrolled consecutive spontaneous pneumothorax patients over 15 years of age. Each data related to individual patients were collected in predefined proforma. To study follow up outcome of management, we used OPD attendance or if not possible took, at least two telephone numbers from the patients. All patients were followed for recurrences. Data was statistically analyzed using SPSS software. Result Over the last 3 years, we enrolled 65 spontaneous pneumothorax patients. Secondary spontaneous pneumothorax was more common (92.3%). Commonest presentations were acute pleuritic chest pain (92.3%), dyspnea (84.62%) and cough (92.3%). COPD (46.14%), PTB sequelae (15.38%), bronchiectasis (23.07%) and bullous lung disease (23.07%) were common risk factors. Tube thoracostomy (95.38%) with pleurodesis with iodopovidone (84.61%) led to lung expansion in 92.3% cases. During follow up, only 4.61% had recurrences of pneumothorax. There was one mortality. Conclusion Spontaneous pneumothorax is a common pulmonary emergency. Meticulous and careful assessment of the patients may help reach the diagnosis even in primary care setting. Tube thoracostomy followed by pleurodesis with iodo-povidone suffices in most circumstances leading lower future recurrences.

Abstract
Abstract
Introduction
Insomnia is frequent in opioid use disorder patients on buprenorphine (OUDB) and increases risk of relapse. There is lack of data evaluating specific differences in hyperarousal and daytime sequelae between OUDBs as compared to individuals with insomnia disorder without (ID) or with comorbid psychiatric conditions (CID).
Methods
We studied 112 patients with ID (47.8±16.3y, 55% female, 13% minority) and 148 with CID (44.7±15.6y, 69% female, 16% minority) evaluated at the Behavioral Sleep Medicine program of Penn State Hershey Sleep Research & Treatment Center and 71 OUDB (37.8±11.2y, 51% female, 16% minority) evaluated at the Recovery, Advocacy, Empowerment and Service program and WellSpan Internal Medicine clinics (York, PA). Subjects completed the Insomnia Severity Index (ISI), Ford Insomnia Response to Stress (FIRST), Arousal Predisposition Scale (APS), Pre-sleep Arousal cognitive (PSAS-C) and somatic (PSAS-S) Scale, Dysfunctional Beliefs and Attitudes about Sleep Scale (DBAS) and Epworth Sleepiness Scale (ESS). Excessive daytime sleepiness (EDS) was defined as an ESS score ≥ 10. MANCOVA included age, sex, race/ethnicity and depression as covariates, while logistic regression further included ISI, APS and PSAS-S.
Results
No differences across groups were observed in PSAS-C or DBAS scores. Subjects with CID and OUDB had significantly higher PSAS-S (15.7±0.5 and 16.4±0.7, respectively) and APS (35.6±0.6 and 36±1, respectively) scores as compared to the ID group (14.2±0.6 and 33.2±0.7, respectively). Subjects with OUDB had significantly higher ESS score (9.8±0.6) as compared to the ID or CID groups (6.2±0.5 and 6.4±0.4, respectively). The odds of EDS were 2.7 times (95%CI=1.2-6.1) higher in the OUDB group as compared to the ID group.
Conclusion
OUDB may present with similar phenotypic insomnia symptoms as patients with ID or CID but report more sleep-disturbing somatic symptoms and EDS. These data have important implications for tailoring behavioral and pharmacological treatments of insomnia to this specific patient population.

Abstract
BACKGROUND Intravenous iron sucrose is a promising therapy for increasing haemoglobin concentration; however, its effect on clinical outcomes in pregnancy is not yet established. We aimed to assess the safety and clinical effectiveness of intravenous iron sucrose (intervention) versus standard oral iron (control) therapy in the treatment of women with moderate-to-severe iron deficiency anaemia in pregnancy. METHODS We did a multicentre, open-label, phase 3, randomised, controlled trial at four government medical colleges in India. Pregnant women, aged 18 years or older, at 20-28 weeks of gestation with a haemoglobin concentration of 5-8 g/dL, or at 29-32 weeks of gestation with a haemoglobin concentration of 5-9 g/dL, were randomly assigned (1:1) to receive intravenous iron sucrose (dose was calculated using a formula based on bodyweight and haemoglobin deficit) or standard oral iron therapy (100 mg elemental iron twice daily). Logistic regression was used to compare the primary maternal composite outcome consisting of potentially life-threatening conditions during peripartum and postpartum periods (postpartum haemorrhage, the need for blood transfusion during and after delivery, puerperal sepsis, shock, prolonged hospital stay [>3 days following vaginal delivery and >7 days after lower segment caesarean section], and intensive care unit admission or referral to higher centres) adjusted for site and severity of anaemia. The primary outcome was analysed in a modified intention-to-treat population, which excluded participants who refused to participate after randomisation, those who were lost to follow-up, and those whose outcome data were missing. Safety was assessed in both modified intention-to-treat and as-treated populations. The data safety monitoring board recommended stopping the trial after the first interim analysis because of futility (conditional power 1·14% under the null effects, 3·0% under the continued effects, and 44·83% under hypothesised effects). This trial is registered with the Clinical Trial Registry of India, CTRI/2012/05/002626. FINDINGS Between Jan 31, 2014, and July 31, 2017, 2018 women were enrolled, and 999 were randomly assigned to the intravenous iron sucrose group and 1019 to the standard therapy group. The primary maternal composite outcome was reported in 89 (9%) of 958 patients in the intravenous iron sucrose group and in 95 (10%) of 976 patients in the standard therapy group (adjusted odds ratio 0·95, 95% CI 0·70-1·29). 16 (2%) of 958 women in the intravenous iron sucrose group and 13 (1%) of 976 women in the standard therapy group had serious maternal adverse events. Serious fetal and neonatal adverse events were reported by 39 (4%) of 961 women in the intravenous iron sucrose group and 45 (5%) of 982 women in the standard therapy group. At 6 weeks post-randomisation, minor side-effects were reported by 117 (16%) of 737 women in the intravenous iron sucrose group versus 155 (21%) of 721 women in the standard therapy group. None of the serious adverse events was found to be related to the trial procedures or the interventions as per the causality assessment made by the trial investigators, ethics committees, and regulatory body. INTERPRETATION The study was stopped due to futility. There is insufficient evidence to show the effectiveness of intravenous iron sucrose in reducing clinical outcomes compared with standard oral iron therapy in pregnant women with moderate-to-severe anaemia.

Abstract
Single Nucleotide Polymorphism (SNP) is one of the important molecular markers widely used in animal breeding program for improvement of any desirable genetic traits. Considering this, the present study was carried out to identify, annotate and analyze the SNPs related to four important traits of buffalo viz. milk volume, age at first calving, post-partum cyclicity and feed conversion efficiency. We identified 246,495, 168,202, 74,136 and 194,747 genome-wide SNPs related to mentioned traits, respectively using ddRAD sequencing technique based on 85 samples of Murrah Buffaloes. Distribution of these SNPs were highest (61.69%) and lowest (1.78%) in intron and exon regions, respectively. Under coding regions, the SNPs for the four traits were further classified as synonymous (4697) and non-synonymous (3827). Moreover, Gene Ontology (GO) terms of identified genes assigned to various traits. These characterized SNPs will enhance the knowledge of cellular mechanism for enhancing productivity of water buffalo through molecular breeding.

Abstract
In this project, we are trying to review the articles that discuss the relationship between insulin signaling and Alzheimer's disease (AD). Another focus of this project is to find the best treatment regimen that can reduce the progression of AD in patients with impaired glucose metabolism. We used Pubmed database to collect our data and used the following keywords: Alzheimer’s disease, insulin signaling pathway, type 3 diabetes, type 2 diabetes, insulin, and insulin resistance in our revision; we included free articles that were published in the last 10 years and excluded articles that were written in any language other than English. We reviewed 68 articles. Forty-nine out of 68 articles were containing materials that are relevant for this project. We found that there is a relation between AD and the insulin signaling pathway. Insulin signaling pathway impairment leads to hyperphosphorylation of Tau protein, which plays a vital role in AD pathology. The effect of insulin on cognition is bidirectional; the intranasal route of insulin showed to have a promising effect on cognition improvement. Subcutaneous and intravenous insulin can increase the risk of dementia. Further studies are encouraged to use a specific anti-diabetic medication that can reduce the progression of AD.
