Abstract
PURPOSE To assess whether Ultrasound guided dry needling is adequate for both common extensor tendon tears and tendinosis or whether ultrasound guided platelet rich plasma (PRP) has a superior outcome when compared to dry needling when there are tears of the common extensor tendon. MATERIALS AND METHODS This is a single-centre, single-blinded, randomised controlled trial conducted between November 2018 and April 2020. 40 patients diagnosed with lateral epicondylitis based on clinical and sonographic features and having comparable baseline characteristics were randomly assigned to the two study groups (dry needling and PRP). Inclusion criteria were patients aged 20 years or more who were symptomatic for at least 3 months with sonographic evidence of lateral epicondylitis. Exclusion criteria were complete tear of common extensor tendon confirmed on ultrasound and presence of other associated diseases like osteoarthritis of shoulder and elbow. RESULTS There was significant improvement in the visual analogue scale pain score in PRP group compared to the dry needling group at 9 months. However, this difference was not evident at 3 and 6 months follow-up. Mean improvement in common extensor tendon thickness in PRP group (5.1 mm at 3 months and 4.3 mm at 6 months) was slightly better than dry needling (4.4 mm at 3 months and 4.0 mm at 6 months). There was no difference in tear (if present) healing between both groups at 3 months. However at 6 months follow up, PRP demonstrated significant (mean-2.5) healing in tear compared to dry needling (mean-3.1). CONCLUSION Two injections of Ultrasound guided PRP are more beneficial non operative treatment compared to ultrasound guided dry needling, in lateral epicondylitis.

Abstract
Green coffee powder is the raw powder of coffee cherries and all coffee's potential components are held within this green powder. A new natural colourant was extracted from Green Coffee using water as an extractant. To obtain a green-colored solution, a specific amount of green coffee was mixed with distilled water and left for 24 h at room temperature. Furthermore, the colouring performance of extracted colour has been studied using the conventional exhaust dyeing method on wool fabric. Different parameters viz. concentration of Green coffee powder, the temperature of the dye bath, the period for immersion, and solution pH were made to set to obtain a fine tone of green colour. The dyeing parameters (amount of the coffee: 2 g, 100 °C, 70 min & 6.7 pH) were optimised and selected to draw a comparison with the conventional Brown coffee powder. In experiments on wool, this potential solution of Green coffee offered rich green hues with good tonal variation. In addition, the colour fastness to washing was found superior in the case of both Green and Brown coffee and colour fastness to light, rubbing as well as perspiration also showed good performance. In this study, our main focus was to obtain the true and fast green tone of the fabric using Green Coffee and compare it with brown coffee using the same conditions used for dyeing with green coffee. The application of these dyes as natural dyes results in obtaining innovative natural fast colour with remarkable dyeing properties and a new inclusion to the existing commercial spectra of natural dyes.

Abstract
Brucellosis is a neglected zoonosis that affects animals and people in much of the underdeveloped world. The disease is endemic in cattle in Punjab, India and controlling it is a public health challenge. Dairy farmers and farm labour commonly handle cattle faeces with bare hands and personal protective equipments are not used. No studies have been conducted about the shedding of Brucella species in faeces of sero positive cattle in the state. This study aimed to isolate and identify the Brucella species from faeces of sero positive cattle in Punjab, India. Faecal samples were collected from 350 Brucella sero positive cattle in Ludhiana district of Punjab, India. Isolation was performed using a pre-enriched Brucella selective broth medium as well as Brucella selective medium agar plates containing horse serum and Brucella selective supplements. Isolates were identified using Gram staining technique and rapid slide agglutination test, and then confirmed by using bcsp31 and 16s rRNA genus specific PCR. Isolates were further identified up to species level by using Bruce-Ladder multiplex PCR. Fourteen Brucella species were isolated, all of which showed coccobacilli on gram staining, positive rapid slide agglutination test and amplification of bcsp31 and 16s rRNA genes. Of the 14 isolates, 11 were identified as Brucella abortus and 3 were identified as Brucella melitensis. The study demonstrates that animal faeces could pose a potential risk for animal and human health and faeces of seropositive cattle must be handled with care.

Abstract
CONTEXT This study aims to investigate the electronic transport properties of tetracene molecule connected to gold (Au) electrodes with asymmetric anchoring groups. More specifically, we investigate the effect of asymmetric electrode coupling on the rectification ratio of tetracene-based molecular device. To introduce coupling asymmetry in these junctions, one end of the tetracene molecule is terminated with thiol (-SH) or isocyanide (-NC) while the other end with amine (-NH2) or nitro (-NO2) anchoring group. The results indicate that the electronic transport behavior is affected by the nature of molecule-electrode coupling, and the rectification ratio can be modulated by a proper choice of the anchoring groups. We reveal that the tetracene molecule when connected with isocyanide and amine combination exhibits remarkable rectifying performance (with a rectification ratio of 74) in contrast with other configurations. Furthermore, a prominent negative differential resistance (NDR) feature is observed when the molecule is connected with thiol as one of the anchors. Our present findings with excellent rectifying performance and negative differential resistance pave a new roadmap for designing multifunctional molecular devices. METHODS By applying non-equilibrium Green's function (NEGF) formalism combined with density functional theory (DFT) Atomistic Tool Kit software package, the electronic transport properties of tetracene molecule connected to gold electrodes with asymmetric anchoring groups have been investigated. The calculations were performed using the Perdew-Burke-Ernzerhof (PBE) parameterization of DFT within generalized gradient approximation (GGA) exchange-correlation functional. To improve calculation precision and save computational efforts, the molecule and anchor groups were double-ζ (DZ) polarized, while single-ζ (SZ) polarized basis set was used for gold electrodes.

Abstract
Prolonged inflammation can impede wound healing, which is regulated by several proteins and cytokines, including IL-4, IL-10, IL-13, and TGF-β. Concentration-dependent effects of these molecules at the target site have been investigated by researchers to develop them as wound-healing agents by regulating signaling strength. Nanotechnology has provided a promising approach to achieve tissue-targeted delivery and increased effective concentration by developing protein-functionalized nanoparticles with growth factors (EGF, IGF, FGF, PDGF, TGF-β, TNF-α, and VEGF), antidiabetic wound-healing agents (insulin), and extracellular proteins (keratin, heparin, and silk fibroin). These molecules play critical roles in promoting cell proliferation, migration, ECM production, angiogenesis, and inflammation regulation. Therefore, protein-functionalized nanoparticles have emerged as a potential strategy for improving wound healing in delayed or impaired healing cases. This review summarizes the preparation and applications of these nanoparticles for normal or diabetic wound healing and highlights their potential to enhance wound healing.

Abstract
Tranexamic acid (TXA) has become widely utilized in different specialities including facelift surgery. The aim of this review was to robustly evaluate the quality of available evidence on the efficacy and safety of TXA use in facelift surgery. We searched the MEDLINE (National Institutes of Health, Bethesda, MD), Embase (Elsevier, Amsterdam, the Netherlands), CINAHL (EBSCO Information Services, Ipswich, MA), Cochrane Central Register of Controlled Trials (CENTRAL; Wiley, Hoboken, NJ), Google Scholar (Alphabet Inc. Mountain View, CA), Science Citation Index (Clarivate, London, UK), and Latin American and Caribbean Center on Health Sciences Information (LILACS; São Paulo, Brazil) databases for randomized controlled trials (RCTs) and observational studies. Primary outcomes were blood loss, postoperative hematoma, ecchymosis, and swelling, in addition to technical considerations and complications. We assessed review quality with the AMSTAR 2 tool, study quality with Grading of Recommendations, Assessment, Development, and Evaluations approach (GRADE) tool, and the risk of bias with Cochrane's RoB 2.0 tool for RCTs and ROBINS-I for nonrandomized studies. Of the 368 articles, a total of 3 studies including 150 patients met the inclusion criteria. The RCT reported a significant reduction in postoperative serosanguineous collections in the TXA group (P < .01), and in surgeon-rated postoperative ecchymosis and bruising. The prospective cohort study reported reduced drainage output in first 24 hours in the TXA group (P < .01). The retrospective cohort study reported lower intraoperative blood loss, mean postoperative day 1 drain output, percentage of drain removal on postoperative day 1, and number of days to drain removal in the TXA group (all P < .01). The quality of studies was moderate, and this review was the highest rated compared to previous reviews, as per the AMSTAR 2 tool. Based on limited literature, TXA improves clinical outcomes regardless of the route of administration. Topical TXA is an emerging route, expediting drain removal and reducing blood loss. Future Level I high-quality studies are required.

Abstract
Bovine brucellosis is endemic in cattle in India, however not much is known on the prevalence of this disease in stray cattle populations of the country. This study aimed to estimate the prevalence and identify risk factors associated with brucellosis in the stray cattle populations reared in cow shelters (gaushalas) of Punjab, India. Blood samples were collected from 587 cattle reared in 23 cow shelters in 23 districts (one per district) of the Punjab and were tested using Rose Bengal plate test (RBPT), standard tube agglutination test (STAT) and Indirect Enzyme Linked Immunosorbent Assay (i-ELISA). Information on the sex and breed of the animal, total cattle population and presence of a separate shed for parturition were collected. An animal was considered exposed to Brucella infection based on a positive RBPT or STAT test and a positive i-ELISA test. Explanatory variables for the animal level disease status outcome variable were sex and breed of the animal and at the shelter level were shelter cattle population size and presence of a separate shed for parturition. Univariable binomial exact logistic regression analysis was conducted to assess the association of each explanatory variable with the binary outcome variable. Sixty-two animals were seropositive on RBPT, with an apparent seroprevalence of 10.56% (95% confidence interval [CI]: 8.33%, 13.31%) and the estimated true seroprevalence of 11.48% (95% CI: 8.9%, 14.64%). Sixty three animals were seropositive using STAT [apparent seroprevalence of 10.73% (95% CI: 8.48%, 13.50%) and the estimated true seroprevalence of 10.69% (95% CI: 8.27%, 13.67%)], and 68 using i-ELISA [an apparent seroprevalence of 11.58% (95% CI: 9.24%, 14.43%) and the estimated true seroprevalence of 13.28% (95% CI: 10.50%, 16.66%)]. Cross bred cattle had a lower risk of being test positive (odds ratio 0.16, p = 0.04) as compared to indigenous cattle. Due to a ban on cow slaughter in the country, roaming stray cattle infected with brucellosis present a permanent risk of introduction of disease to the dairy farms and other vulnerable populations.

Abstract
Targeted delivery has not been achieved for anthelmintic treatment, resulting in the requirement of excess drug dose leading to side effects and therapeutic resistance. Gastrointestinal helminths take up lipid droplets from digestive fluid for energy production, egg development, and defense which inspired us to develop biocompatible and orally administrable albendazole-loaded solid lipid nanoparticles (SLN-A) that were derived from beeswax and showed drug loading efficiency of 83.3 ± 6.5 mg/g and sustained-release properties with 84.8 ± 2.5% of drug released at pH 6.4 within 24 h at 37 °C. Rhodamine B-loaded SLN showed time-dependent release and distribution of dye in-vitro in Haemonchus contortus. The sustained-release property was shown by the particles that caused enhancement of albendazole potency up to 50 folds. Therefore, this formulation has immense potential as an anthelminthic drug delivery vehicle that will be able to reduce the dose and drug-induced side effects by enhancing the bioavailability of the drug.

Abstract
Brucellosis imposes substantial impacts on livestock production and public health worldwide. A stochastic, age-structured model incorporating herd demographics was developed describing within- and between-herd transmission of Brucella abortus in dairy cattle herds. The model was fitted to data from a cross-sectional study conducted in Punjab State of India and used to evaluate the effectiveness of control strategies under consideration. Based on model results, stakeholder acceptance and constraints regarding vaccine supply, vaccination of replacement calves in large farms should be prioritized. Test and removal applied at early stages of the control programme where seroprevalence is high would not constitute an effective or acceptable use of resources because significant numbers of animals would be 'removed' (culled or not used for breeding) based on false positive results. To achieve sustained reductions in brucellosis, policymakers must commit to maintaining vaccination in the long term, which may eventually reduce frequency of infection in the livestock reservoir to a low enough level for elimination to be a realistic objective. This work provides key strategic insights into the control of brucellosis in India, which has the largest cattle population globally, and a general modelling framework for evaluating control strategies in endemic settings.

Abstract
Background The term "Telemedicine" is being used in the medical and health sector to treat patients and to provide medical guidance remotely. The intellectual output from India in terms of publications was harvested from Scopus® with the keyword "Telemedicine" and analyzed by using bibliometric techniques. Methods The source data was downloaded from the Scopus® database. All the publications on telemedicine and indexed in the database up to the year 2021 were considered for scientometric analysis. The software tools VOSviewer® version 1.6.18 to visualize bibliometric networks, statistical software R Studio® version 3.6.1 with the Bibliometrix package Biblioshiny® were used for analysis and data visualization, and EdrawMind® was used for mind mapping. Result India contributed 2,391 (4.32%) publications on telemedicine to a total of 55,304 publications worldwide until 2021. There were 886 (37.05%) papers that appeared in open access mode. The analysis revealed that the first paper was published in the year 1995 from India. Steep growth in the number of publications was observed in 2020 with 458 publications. The highest, 54 research publications, appeared in the "Journal of Medical Systems." The All India Institute of Medical Sciences (AIIMS), New Delhi, contributed the highest number of publications (n = 134). A considerable overseas collaboration was observed (USA: 11%; UK: 5.85%). Conclusions This is the first such attempt to address the intellectual output of India in the emerging medical discipline of telemedicine and has yielded useful information such as leading authors, institutions, their impact, and year-wise topic trends.

Abstract
Background Antimicrobial resistance (AMR) is a burning issue in the present era. Mastitis in dairy animals is one of the most important causes of huge production loss to dairy farmers. Aims: The study aims to find the prevalence, antimicrobial resistance profile, and resistance genes in the extended-spectrum beta-lactamase-producing Escherichia coli in mastitic milk. Methods A total of 125 milk samples were collected from Beetal goats suffering from clinical mastitis from different districts of Punjab and processed for bacterial isolation and further identification. The drug resistance profile of ESBL-producing E. coli and its associations with molecular markers was analyzed using statistical analysis. Results The prevalence of ESBL-producing E. coli in dairy goats of Punjab was recorded as 6.4%. The isolates showed the highest resistance to the beta-lactam group of antibiotics. The resistance percentages of streptomycin, gentamicin, tetracycline, chloramphenicol, clotrimazole, and colistin were 50%, 37.5%, 50%, 25%, 25%, and 50%, respectively. The isolates showed intermediate resistance to imipenem (12.5%) and tetracycline (25%). The ESBL-producing E. coli isolates harbored the resistance genes blaCTXM (100%), blaTEM (62.5%), blaSHV (25%), blaOXA (37.5%), tetA (37.5%), tetB (25%), aadA (37.5%), sul1 (25%), MOXM (12.5%), DHAM (25%), and blaCMY-2 (50%). Tetracycline and sulphonamide resistances were statistically associated with their respective resistance genes (P<0.05). Streptomycin resistance was not statistically associated with the presence of the aadA gene (P>0.05). The genes blaIMP and blaNDM were not recorded in any of the isolates. In this study, 12.5% of the isolates showed co-resistance to colistin and carbapenem. Conclusion Antimicrobial resistance is a hot topic and requires immediate attention.

Abstract
SETTING: Multidrug-resistant TB (MDR-TB) clinical trial in Lima, Peru and Cape Town, South Africa.OBJECTIVE: To identify baseline factors associated with screening failure and study withdrawal in an MDR-TB clinical trial.DESIGN: We screened patients for a randomized, blinded, Phase II trial which assessed culture conversion over the first 6 months of treatment with varying doses of levofloxacin plus an optimized background regimen (ClinicalTrials.gov: NCT01918397). We identified factors for screening failure and study withdrawal using Poisson regression to calculate prevalence ratios and Cox proportional hazard regression to calculate hazard ratios. We adjusted for factors with P < 0.2.RESULTS: Of the 255 patients screened, 144 (56.5%) failed screening. The most common reason for screening failure was an unsuitable resistance profile on sputum-based molecular susceptibility testing (n = 105, 72.9%). No significant baseline predictors of screening failure were identified in the multivariable model. Of the 111 who were enrolled, 33 (30%) failed to complete treatment, mostly for non-adherence and consent withdrawal. No baseline factors predicted study withdrawal in the multivariable model.CONCLUSION: No baseline factors were independently associated with either screening failure or study withdrawal in this secondary analysis of a MDR-TB clinical trial.

Abstract
BACKGROUND Cryptosporidium, an opportunistic, zoonotic, apicomplexan parasite, is one of the most common causes of diarrhea in neonatal bovine calves around the globe. Bovine calves act as a major source of infection by excreting huge numbers of highly resistant oocysts in faeces, which can survive for a long time in extreme environmental conditions. As low as ten oocysts can cause disease and mortality, leading to the requirement of an early and accurate diagnosis for proper and favorable prognosis, management, and control. AIMS The current study was conducted with the objective to evaluate various diagnostic techniques (acid fast staining, negative staining, fluorescent, ELISA, PCR, nested PCR, and qPCR) for the detection of Cryptosporidium in the faecal samples of diarrheic bovine calves. METHODS Two hundred diarrheic faecal samples from bovine calves were collected and subjected to these techniques for Cryptosporidium diagnosis. Results of these were evaluated for diagnostic comparison. RESULTS Out of 200 faecal samples evaluated, 24% (48/200) were detected positive for Cryptosporidium using a combination of two techniques as gold standard criteria. Cohen's kappa value indicated moderate to almost perfect agreement (0.616 to 0.986) among all the techniques used in the present study. Leishman staining showed the lowest sensitivity (54.17%), while nested PCR and qPCR showed the highest sensitivity (97.92%). Diagnostic specificity of all these tests ranged from 98.68 to 100%. CONCLUSION Auramine stain was used for the first time in the bovine calves in India for the detection and diagnostic comparison of Cryptosporidium. It showed strong agreement with the molecular as well as classical diagnostic techniques, and can be used for primary screening for better diagnosis.

Abstract
BACKGROUND Bovine tuberculosis (bTB) is a major bacterial disease that causes significant economic disruption across the globe. AIMS Our study was based on using a fluorescence polarization assay (FPA) that used fluorescein-labeled ESAT-6 protein to detect Mycobacterium bovis antibodies in bovine serum. METHODS The ESAT-6 protein was used in a FPA. Positive TB reactors were determined by the comparative intradermal test (CID) and interferon gamma test (IFN-γ). Antibodies against M. bovis were detected using a fluorescein isothiocyanate (FITC) labeled tracer and a whole culture FITC labeled tracer in the positive cattle. RESULTS Of the 192 animals tested for bTB, 37 were found to be positive by either the CID or IFN-γ assays. Using the mP values from five culture-positive serum samples, a cutoff value of more than >127 mp provided the best discrimination between positive reactors and negative bTB animals. The ESAT-6 results of FPA in comparison with CID results revealed sensitivity of 92.9% and specificity of 64.6%, and in comparison with results IFN-γ, showed sensitivity of 95.7% and specificity of 49%. FPA using FITC labelled ESAT-6 as a tracer has better sensitivity (95.7%) and specificity (49.1%) than IFN-γ test in humoral immune response in animals. CONCLUSION This work revealed that the ESAT-6 protein as an antigen can be used in diagnosing bTB using a practical and sensitive humoral test.

Abstract
Background Microbes become unresponsive to the drugs used to treat infections due to their ability to acquire antimicrobial resistance. Aims The present research aimed to study the patterns of phenotypic and genotypic antimicrobial resistance in Staphylococcus spp. isolated from goat milk. Methods A total of 200 milk samples were collected to isolate Staphylococcus spp. from mastitic and healthy goats from Punjab state, India. The isolates were then identified biochemically and molecularly (polymerase chain reaction (PCR)). An antibiotic sensitivity test was conducted using 15 different antibiotics. Molecular detection of antibiotic resistance genes was done using PCR. Chi-square test was done to study the association between genotypic and phenotypic resistance patterns among the isolates. Results A total of 47 Staphylococcus spp. were isolated of which 33 and 14 isolates were respectively coagulase positive and negative. The isolates phenotypically showed the highest resistance to Penicillin G (P) (91.4%). Methicillin resistant Staphylococcus aureus (MRSA) was found 56.25%. Amongst the antibiotic resistance genes, tetK (87.23%) was the most prevalent isolated gene followed by blaZ (85.10%), mecA (48.93%), and tetM (14.89%). Statistical analysis revealed that the genotypic and phenotypic resistance patterns were significantly associated with penicillin and methicillin (MET) resistances. Conclusion The high prevalence of antibiotic-resistant Staphylococcus spp., especially MRSA, in goat milk is of concern and needs to be addressed in this area.

Abstract
Pb-toxicity is associated with inflammation which leads to delay in wound healing. Pb2+ utilizes calcium ion channels to enter the cell. Therefore, to achieve effective healing in a Pb-poisoned system, capturing Pb2+ from the circulatory system would be an effective approach without hampering the activity of the calcium ion channel. In this work insulin–nickel fluorescent quantum clusters (INiQCs) have been synthesized and used for the specific detection of Pb2+ ions in vitro and in cell-free systems. INiQCs (0.09 μM) can detect Pb2+ concentrations as low as 10 pM effectively in a cell-free system using the fluorescence turn-off method. In vitro INiQCs (0.45 μM) can detect Pb2+ concentrations as low as 1 μM. INiQCs also promote wound healing which can easily be monitored using the bright fluorescence of INiQCs. INiQCs also help to overcome the wound recovery inhibitory effect of Pb2+in vitro using lead nitrate. This work helps to generate effective biocompatible therapeutics for wound recovery in Pb2+ poisoned individuals. Receptor targeted ferromagnetic Insulin–Nickel Quantum fluorescence Clusters (INiQCs) can specifically detect Pb2+ and prevents Pb2+ poisoning.![]()

Abstract
Quantum clusters with target specificity are suitable for tissue-specific imaging. In the present work, amorphous zinc insulin quantum clusters (IZnQCs) had been synthesised to promote and monitor wound recovery. Easy synthesis, biocompatibility, stability, enhanced quantum yield, and solubility made the cluster suitable for preclinical/clinical exploration. Zn2+ is known for its binding to insulin hexamer. Here we report the reformation of the structure in a quantum cluster form in the presence of Zn2+. The formation of IZnQCs was confirmed by the change in zeta potential from -25.6 mV to -17.9 mV and also the formation of protein metal interaction was confirmed in FTIR bands at 450, 480, and 613 cm-1 for Zn-O, Zn-N, and Zn-S, respectively. HRTEM-EDS and SAED data analysis showed an amorphous nature of the cluster. The binding of IZnQCs to the cells has been confirmed using confocal microscopy. IZnQCs showed a synergistic effect in wound recovery than insulin or Zn2+ alone. Further due to high fluorescence this recovery process can be monitored under an appropriate setup. Wound healing promotional activity, target specificity, and fluorescence properties make the IZnQCs ideal to use for bioimaging along with promoting and monitoring of wound recovery agent.

Abstract
Here we show the novel anti-helminthic potential of Lansium parasiticum aqueous extract-protected silver nanoparticles (LAgNPs) against albendazole-resistant gastrointestinal parasite Haemonchus contortus. LAgNPs showed LD50 values of 65.6 ± 32.8 nM (12 h), 139.6 ± 39.9 nM (12 h), and 64.3 ± 8.5 nM (24 h) against adult male, female, and L3 larvae, respectively. LAgNPs was also quite effective in inhibiting egg hatching, with an IC50 value of 144.4 ± 3.1 nM at 48 h of exposure. Exposure to LAgNPs generated oxidative stress and mediated physical damage in the worms' tissue. A sharp increase in reactive oxygen species and nitric oxide synthase levels was prominent due to LAgNPs' exposure. In response to oxidative stress, a sharp increase of stress-responsive enzymes' activity, like catalase, superoxide dismutase, and glutathione peroxidase activity, along with the concentration of glutathione, was observed in worm tissue, which indicated a LAgNP-responsive alteration of metabolism. The results give rise to the opportunity for the development of alternative treatment for drug-resistant parasitic worms.

Abstract
Objective Our study aimed to assess the risk of in-patient mortality due to renal failure and other comorbidities in aortic stenosis (AS) patients undergoing transcatheter aortic valve replacement (TAVR). Methods We conducted a cross-sectional study using a Nationwide Inpatient Sample (NIS, January 2010 to December 2014) from the United States and included 33,325 patients with a primary diagnosis of AS. Logistic regression was used to evaluate the odds ratio (OR) for in-hospital mortality in AS by comorbidities including renal failure. Results The prevalence of renal failure in AS patients is 29.2%, and a higher proportion were males (60.1%) and non-white (14.1%). Major loss of function (96.6%) and in-hospital mortality (5.1%) were also proportionally higher in prevalence. Female patients (OR 1.35, 95% CI 1.20-1.51) had higher odds of in-patient mortality in AS patients. Race was a non-significant predictor for mortality risk. Patients with comorbid coagulopathy (OR 2.02, 95% CI 1.79-2.27) and heart failure (OR 1.62, 95% CI 1.39-1.89) have increased mortality in AS inpatients. After controlling confounders, renal failure was significantly associated with increased in-hospital mortality (OR 1.43, 95% CI 1.28-1.61) in AS patients. Conclusion Renal failure was prevalent in AS patients and was an independent factor that increases the risk of in-hospital mortality by 43%. Due to worse outcomes, more studies are required to evaluate risk-benefit ratio and strategies to improve health-related quality of life in post-TAVR patients with renal failure, and optimally decrease inpatient mortality.

Abstract
Objectives We used the Nationwide Inpatient Sample (NIS) to identify the demographic predictors and study the impact of chronic comorbidities on the risk of in-hospital mortality in Alzheimer’s disease (AD). Methods We included 132,405 AD patients from the NIS (2012-2014). We used descriptive statistics to discern the differences in demographics and comorbidities by in-hospital mortality. Logistic regression analysis was used to evaluate the predictors and impact of comorbidities that increase the risk of association with in-hospital mortality. Results The in-hospital mortality in AD inpatients is 1.69%, and a greater proportion were female (58.4%) and white (81.5%). Male and hispanic had a higher mortality risk than their counterparts. Hypertension (72%) is the most prevalent comorbidity. Congestive cardiac failure (CCF) and renal failure were significantly associated with a higher risk of in-hospital mortality in AD inpatients by 1.4 and 1.5 times, respectively. Psychiatric comorbidities (depression 20.4%, and psychosis 21.4%) were prevalent in AD inpatients but were negatively associated with mortality. Comorbid tumors without metastasis (1.2%) and metastatic cancer (0.3%) were least prevalent but significantly increased the risk of in-hospital mortality by 1.6 times and 2.2 times, respectively. Conclusion CCF and renal failure were significantly associated with a higher risk of in-hospital mortality in AD patients. Less prevalent comorbidities, tumors with/without metastasis increased in-hospital mortality by 59% to 117%. An integrated care model is required to manage comorbidities in AD patients to improve health-related quality of life and reduce morbidity and mortality.

Abstract
AIMS In cardiomyocytes, there is microRNA (miR) in the mitochondria that originates from the nuclear genome and matures in the cytoplasm before translocating into the mitochondria. Overexpression of one such miR, miR-181c, can lead to heart failure by stimulating reactive oxygen species (ROS) production and increasing mitochondrial calcium level ([Ca2+]m). Mitochondrial calcium uptake 1 protein (MICU1), a regulatory protein in the mitochondrial calcium uniporter complex, plays an important role in regulating [Ca2+]m. Obesity results in miR-181c overexpression and a decrease in MICU1. We hypothesize that lowering miR-181c would protect against obesity-induced cardiac dysfunction. METHODS AND RESULTS We used an in vivo mouse model of high-fat diet (HFD) for 18 weeks and induced high lipid load in H9c2 cells with oleate-conjugated bovine serum albumin in vitro. We tested the cardioprotective role of lowering miR-181c by using miR-181c/d-/- mice (in vivo) and AntagomiR against miR-181c (in vitro). HFD significantly upregulated heart levels of miR-181c and led to cardiac hypertrophy in wild-type mice, but not in miR-181c/d-/- mice. HFD also increased ROS production and pyruvate dehydrogenase activity (a surrogate for [Ca2+]m), but the increases were alleviated in miR-181c/d-/- mice. Moreover, miR-181c/d-/- mice fed a HFD had higher levels of MICU1 than did wild-type mice fed a HFD, attenuating the rise in [Ca2+]m. Overexpression of miR-181c in neonatal ventricular cardiomyocytes (NMVM) caused increased ROS production, which oxidized transcription factor Sp1 and led to a loss of Sp1, thereby slowing MICU1 transcription. Hence, miR-181c increases [Ca2+]m through Sp1 oxidation and downregulation of MICU1, suggesting that the cardioprotective effect of miR-181c/d-/- results from inhibition of Sp1 oxidation. CONCLUSION This study has identified a unique nuclear-mitochondrial communication mechanism in the heart orchestrated by miR-181c. Obesity-induced overexpression of miR-181c increases [Ca2+]m via downregulation of MICU1 and leads to cardiac injury. A strategy to inhibit miR-181c in cardiomyocytes can preserve cardiac function during obesity by improving mitochondrial function. Altering miR-181c expression may provide a pharmacologic approach to improve cardiomyopathy in individuals with obesity/type 2 diabetes.

Abstract
Objective Our study aimed to assess the risk of in-hospital mortality due to chronic alcoholic liver disease (CALD) and other comorbidities in spontaneous bacterial peritonitis (SBP) inpatients. Methods We conducted a cross-sectional study using the Nationwide Inpatient Sample (NIS, 2012 to 2014) from the United States and included 6,530 patients (age 18-50 years) with a primary diagnosis of SBP. Logistic regression was used to evaluate the odds ratio (OR) for in-hospital mortality in SBP by comorbidities. Results The prevalence of CALD in SBP patients is 43.6%, and a higher proportion were males (68.8%) and whites (67%). Middle-aged adults (OR 2.8, 95% CI 1.74-4.45) had higher odds of in-hospital mortality in SBP patients. Race and sex were non-significant predictors for mortality risk. Patients with comorbid coagulopathy (OR 1.9, 95% CI 1.45-2.48) and heart failure (OR 3.9, 95% CI 2.46-6.36) have increased mortality in SBP inpatients. After controlling confounders, CALD was significantly associated with increased in-hospital mortality (OR 1.5, 95% CI 1.12-1.94) in SBP inpatients. Conclusion CALD is an independent factor in increasing the risk of in-hospital mortality in SBP patients by 48%. Alcohol use screening, and alcohol abstinence and supportive therapy need to be implemented at an earlier stage to improve health-related quality of life and reduce in-hospital mortality in SBP patients.

Abstract
Bovine tropical theileriosis caused by Theileria annulata is an overwhelming haemoprotozoan tick-borne disease in taurine and cross-bred cattle in Punjab, India. However, there seems to be no report from India of cutaneous nodules associated with the disease. This report describes a five-year-old cross-bred cow presented to a university clinic with a history of fever, inappetence and malaise for the past six to seven days. Clinical examination revealed normal vital parameters, pale mucous membranes, mild enlargement of the prescapular lymph nodes and multiple subcutaneous nodular masses (2-4 cm) on the neck and abdomen. Haematology revealed mild anaemia and leucopenia with 48% neutrophils, 48% lymphocytes and 4% eosinophils. Romanowsky-stained smears of fineneedle aspiration biopsy samples from swollen lymph nodes and subcutaneous masses showed an increased number of lymphoid cells, suggesting cutaneous lymphomatosis. However, a critical examination of the smears from subcutaneous nodules showed a large number of Koch's blue bodies in macrophages and lymphoblasts, and several piroplasms were also noticed within the red blood cells in lymph node smears. A peripheral blood smear revealed mild to moderate parasitaemia. Extracted DNA from the parasitologically positive blood sample was subjected to nested polymerase chain reaction (nPCR) using T. annulata speciesspecific primers encoding the 30-kiloDalton major sporozoite surface antigen. The desired 572-base pair amplified product of the nPCR was comparable to the positive control. This seems to be a rare case of T. annulata in an adult cross-bred cow, showing cutaneous nodular involvement.

Abstract
Protein embedded fluorescence quantum clusters (QCs) have received a great amount of interest among the researchers because of their high aqueous solubility, stability, cost efficiency, and target specificity. Considerable advancement has happened in making functional quantum clusters with target specificity. This work reports the simple synthesis of insulin protected copper quantum clusters (ICuQCs) and its receptor-targeted bioimaging applications. The preparation of copper quantum clusters (CuQCs) was done simply by one-pot synthesis method by changing the pH of the insulin protein firstly to 10.5 basic pH than physiological pH. At physiological pH, the mixture incubated in oven 37 ⁰C at 240 rpm has been developed to process initially polydisperse, non-fluorescent, and unstable CuDs into monodispersed (∼2-3 nm), highly fluorescent, and extremely stable ICuQCs in the same phase (aqueous) using insulin as protein. HRTEM image show uniform distribution of CuDs within the protein matrix. Metal ion binding site prediction and docking server (MIB) results show that chain B of insulin contains 3 templates contains 5 amino acid residues which bind with Cu2+ metal ion. Groove 1 contains GLY8 and HIS10 bind has the highest binding potential towards Cu metal ions. The methodology adopted in this study should largely contribute to the practical applications of this new class of QCs. In view of the protein protection, coupled with direct synthesis and easy functionalization, this hybrid QC-protein system is expected to have numerous optical and bioimaging applications in the future.

Abstract
The steady-state fluctuation theorem (SSFT) gives the relative probability of occurrence of events violating the second law of thermodynamics in a system with a small number of degrees of freedom. Using two-dimensional complex plasma as a working medium, wherein particle level observation of instantaneous velocities and positions has become experimentally possible, we perform "first-principles" molecular-dynamics simulations using the Yukawa potential in the presence of external gravity and an external temperature gradient leading to the onset and formation of Rayleigh-Bénard convection cells. In such a far-from-equilibrium steady state, the SSFT is put to the test. It is demonstrated that the SSFT is satisfied without any additional fit parameter for observation time τ, comparable to or greater than the relevant microscopic timescale associated with the system under observation.

Abstract
Phosphopantetheine adenylyl transferase catalyzes a rate limiting penultimate step of the multistep reaction which produces coenzyme A (CoA) as a final product. CoA is required as an essential cofactor in a number of metabolic reactions. Therefore inhibiting the function of this enzyme will lead to cell death in bacteria. Acinetobacter baumannii is multi drug resistant pathogen and causes infections in immunocompromised patients. AbPPAT has been cloned, expressed, purified and crystallized and structures of two complexes of AbPPAT with dephospho coenzyme A (dPCoA) and coenzyme A (CoA) have been determined. Both dPCoA and CoA molecules are observed in the substrate binding site of AbPPAT. A comparison with the structures of the complexes of PPAT from other species shows that the orientations of dPCoA are identical in all the structures. On the other hand, as observed from the structures of the complexes of CoA with PPAT, the orientations of CoA are found to differ considerably. This shows that the substrates occupy identical positions in the substrate binding sites of enzymes whereas the positions of inhibitors may differ. The binding studies carried out using fluorescence method and surface plasmon resonance techniques showed that binding affinity of CoA towards AbPPAT is nearly three times higher than that of dPCoA.

Abstract
Background The evidence regarding the prognostic impact of a positive circumferential resection margin (CRM) in oesophageal cancer is conflicting, and there is global variability in the definition of a positive CRM. The aim of this study was to determine the impact of a positive CRM on survival in patients undergoing oesophagectomy for oesophageal cancer. Methods A systematic review and meta‐analysis was performed. PubMed and Embase databases were searched for articles to May 2018 examining the effect of a positive CRM on survival. Cohort studies written in English were included. Meta‐analyses of univariable and multivariable hazard ratios (HRs) were performed using both Royal College of Pathologists (RCP) and College of American Pathologists (CAP) criteria. Risk of bias was assessed using the Newcastle–Ottawa Scale. Egger regression, and Duval and Tweedie trim‐and‐fill statistics were used to assess publication bias. Results Of 133 studies screened, 29 incorporating 6142 patients were finally included for analysis. Pooled univariable HRs for overall survival in patients with a positive CRM were 1·68 (95 per cent c.i. 1·48 to 1·91; P < 0·001) and 2·18 (1·84 to 2·60; P < 0·001) using RCP and CAP criteria respectively. Subgroup analyses demonstrated similar results for patients by T category, neoadjuvant therapy and tumour type. Pooled HRs from multivariable analyses suggested that a positive CRM was independently predictive of a worse overall survival (RCP: 1·41, 1·21 to 1·64, P < 0·001; CAP: 2·37, 1·60 to 3·51, P < 0·001). Conclusion A positive CRM is associated with a worse prognosis regardless of classification system, T category, tumour type or neoadjuvant therapy.

Abstract
AbstractFour hundred and twenty-two million people have diabetes due to excess free body glucose in their body fluids. Diabetes leads to various problems including retinopathy, neuropathy, arthritis, damage blood vessels etc; it also causes a delay in wound healing. Insufficiency of insulin is the main reason for diabetes-I and systemic insulin treatment is a remedy. The perspective of the potential use of insulin/insulin based drugs to treat chronic wounds in diabetic conditions is focused on in this review. At the site of the wound, TNF-ɑ, IFN-ϒ, IL-1β and IL-6 pro-inflammatory cytokines cause the generation of free radicals, leading to inflammation which becomes persistent in diabetes. Insulin induces expression of IL-4/IL-13, IL-10 anti-inflammatory cytokines etc which further down-regulates NFkβP50/P65 assembly. Insulin shifts the equilibrium towards NFkβP50/P50 which leads to down-regulation of inflammatory cytokines such as IL-6, IL-10 etc through STAT6, STAT3 and c-Maf activation causing nullification of an inflammatory condition. Insulin also promotes protein and lipid biosynthesis which indeed promotes wound recovery. Here, in this article, the contributions of insulin in controlling wound tissue microenvironments and remodulation of tissue have been summarised, which may be helpful to develop novel insulin-based formulation(s) for effective treatment of wounds in diabetic conditions.

Abstract
Abstract
Introduction
Controversy exists with regards to the optimal regimen for neoadjuvant chemotherapy (NAC) of TNBC. Platinum-based regimens seem to be more active in TNBC improving pCR rates significantly. But adding platinum to an anthracycline/taxane chemotherapy regime comes at the expense of greater toxicity. Its impact on survival and long-term-outcomes remains undetermined. Practical guidelines vary across leading international professional societies. In this real-world multicenter study neoadjuvant regimens, pCR rates and survival were evaluated.
Material and methods
This study was conducted from 2012-2017 in six certified breast cancer centers in the region of Hanover, Germany, including rural and urban populations by using a personal questionnaire and data from the medical records. All patients with primary TNBC (ER<1%, PR<1%, Her2/neu 0, 1+ or 2+ FISH/CISH negative) and no evidence of distant disease were eligible.
Results
143/217 patients (66%) received NAC and 74/217patients (34%) adjuvant chemotherapy. 63/143 (44%) patients achieved pCR. 23/63 (35%) received platinum-based NAC and 40/63 (65%) received chemotherapy without platinum. In 80 patients pCR was not achieved. 12/80 patients received platinum and 68/80 non platinum-based NAC. pCR was significantly higher among patients with platinum-based chemotherapy (chi-square, p < 0.003). 20/23 patients who achieved pCR received NAC containing anthracycline/taxane/carboplatin, 3/23 patients received a taxane/carboplatin-based regime. Treatment discontinuation was seen in 12/35 (34%) patients receiving platinum-based NAC vs 15/108 (14%) in non-platinum-based NAC. Mean follow up was 17 months (1-70months). A significant difference in OS (p=0.007) and DFS (p=0.001) was seen for patients with a pCR.
Conclusion
Our trial confirms that platinum based NAC achieves significantly higher rates of pCR in patients with TNBC. pCR was associated with significantly longer DFS and OS. The CALBG protocol (CALBG 40603) was the preferred choice of treatment regimen followed by the GeparSixto protocol. In our study the pCR rate was comparable to that of both trials in which pCR rates of 60% (CALBG 40603) and 53% (GeparSixto) were achieved. However, in our trial 34% of the patients discontinued treatment due to toxicity. Therefore these protocols should be used in carefully selected patients. In a real world setting less toxic chemotherapy regimens achieved a pCR rate of 37%. In terms of toxicity and adherence to chemotherapy, these regimens are reasonable alternative options. In daily care close monitoring of treatment response is essential during NAC. In patients who have a rapid clinical response to platinum-free NAC the benefit of adding platinum is questionable. In contrast, the addition of platinum seems to be appropriate in those patients who show only limited response under NAC.

Abstract
Background: Tetrahydroindazole, a member of the fused-pyrazole system, is a least studied
class of heterocyclic compounds owing to its scarcity in nature. However, a large number of synthetically
prepared tetrahydroindazoles are known to show a variety of biological activities such as interleukin-
2 inducible T-Cell kinase inhibitors, AMPA receptor positive allosteric modulators, antitumor,
antituberculosis, anti-inflammatory and antimicrobial activities. Vilsmeier-Haack reaction is one of the
most important chemical reactions used for formylation of electron rich arenes. Even though Vilsmeier-
Haack reaction was studied on a wide variety of hydrazones derived from active methylene
compounds, literature lacks the examples of the use of 4-substituted cyclohexanones as a substrate for
the synthesis of 4,5,6,7-tetrahydroindazoles. The study of the reaction of Vilsmeier-Haack reagent with
hydrazones derived from cyclic keto compounds having active methylene has been considered the interested
topic of investigation. In the present study, ethyl cyclohexanone-4-carboxylate was treated
with one equivalent of various hydrazines for two hours and the resulted hydrazones were further
treated with an OPC-VH reagent (Vilsmeier-Haack reagent isolated from phthaloyl dichloride and N,Ndimethylformamide)
afforded 4,5,6,7-tetrahydroindazoles in excellent yields. The synthesized compounds
4a-f and 5a-f were screened for their antioxidant activities using the DPPH radical scavenging
assay. The target compounds were synthesized regioselectively using 4+1 approach in excellent yields.
A number of experiments using both conventional heating as well as microwave irradiation methods
were tried and on comparison, microwave irradiation method was found excellent in terms of easy
work up, high chemical yields, shortened reaction times, clean and, no by-products formation. Some of
the synthesized compounds showed significant antioxidant activity. The microwave assisted synthesis
of 4,5,6,7-tetrahydroindazoles from ethyl cyclohexanone-4-carboxylate has been reported under mild
conditions in excellent yield. Easy work up, high chemical yield, shortened reaction times, clean and
no by-products formation are the major advantages of this protocol. These advantages may make this
method useful for chemists who are interested in developing novel 4,5,6,7-tetrahydroindazole based
drugs.
