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
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
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
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
Crop domestication has a tremendous impact on socioeconomic conditions and human civilization. Modern cultivars were domesticated from their wild progenitors thousands of years ago by the selection of natural variation by humans. New cultivars are being developed by crossing two or more compatible individuals. But the limited genetic diversity in the cultivars severely affects the yield and renders the crop susceptible to many biotic and abiotic stresses. Crop wild relatives (CWRs) are the rich reservoir for many valuable agronomic traits. The incorporation of useful genes from CWR is one of the sustainable approaches for enriching the gene pool of cultivated crops. However, CWRs are not suited for urban and intensive cultivation because of several undesirable traits. Researchers have begun to study the domestication traits in the CWRs and modify them using genome-editing tools to make them suitable for extensive cultivation. Growing evidence has shown that modification in these genes is not sufficient to bring the desired change in the neodomesticated crop. However, the other dynamic genetic factors such as microRNAs (miRNAs), transposable elements, cis-regulatory elements and epigenetic changes have reshaped the domesticated crops. The creation of allelic series for many valuable domestication traits through genome editing holds great potential for the accelerated development of neodomesticated crops. The present review describes the current understanding of the genetics of domestication traits that are responsible for the agricultural revolution. The targeted mutagenesis in these domestication genes via clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated protein 9 could be used for the rapid domestication of CWRs.

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 Brown planthopper (BPH), Nilaparvata lugens (Stål), is one of the most destructive pests of rice accounting for 52% of annual yield loss. The breakdown of resistance against known BPH biotypes necessitates the identification and deployment of new genes from diverse sources. The current study aimed at mapping and transfer of a novel BPH resistance gene from the wild species of rice O. rufipogon accession CR100441 to the elite rice cultivar against BPH biotype 4. METHODS AND RESULTS The phenotypic screening against BPH biotype 4 was conducted using the standard seedbox screening technique (SSST). Inheritance study using damage score caused by BPH infestation at the seedling stage indicated the presence of a single major recessive gene with the segregation ratio of susceptible to resistant plants in 3:1 (210:66, χ2c = 0.17 ≤ χ20.05,1 = 3.84). The genotyping of the mapping population was done using polymorphic microsatellite markers between PR122 and O.rufipogon acc.CR100441 spanning all the 12 chromosomes of rice. A total of 537 SSR markers were used to map a BPH resistance gene (designated as bph42) on the short arm of chromosome 4 between RM16282 and RM6659. QTL analysis identified a peak marker RM16335 contributing 29% of the phenotypic variance at 40.76 LOD. CONCLUSIONS The identified marker co-segregates with the bph42 and hence could be efficiently used for marker-assisted selection (MAS) for the transfer of resistance into elite rice cultivars. The introgression lines with higher yield and BPH resistance were identified and are under advanced yield trails for further varietal release.

Abstract
Administering myelosuppressive chemotherapy to patients with aggressive malignant hematologic disorders typically poses serious infectious complications, which can be exacerbated by the presence of active COVID-19 infection. We report on a case of a successfully treated fit elderly woman with refractory acute myeloid leukemia (AML) who also had mild COVID-19 infection and detectable viral load at the time she was found to have recurrent disease. Prior to initiation of reinduction treatment with cytarabine/idarubicin, this 2-dose COVID-19-vaccinated patient received antiviral therapy with remdesivir with resolution of upper respiratory symptoms. This was followed by sotrovimab on the third day of chemotherapy. Throughout her hospital course, she remained hemodynamically stable with one episode of neutropenic fever without other identified infections. Symptomatic reactivation of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causing COVID-19 was not observed. After achieving biopsy-confirmed morphologic remission of AML and with neutrophil recovery, the patient gradually cleared the virus, eventually testing negative on polymerase chain reaction test of the nasopharynx. This case underlines the importance of considering initiation of timely chemotherapy, although myelosuppressive, in appropriate patients with aggressive hematologic malignancies and concomitant SARS-CoV-2. It demonstrates management of active COVID-19 infection in this group of patients and the dynamics of SARS-CoV-2 viral load during leukemia treatment.

Abstract
Abstract
Introduction Fine-needle aspiration cytology (FNAC) is an easy, quick, and specialized technique to distinguish neoplastic from non-neoplastic adrenal lesions, yet limited to tertiary care centers. It helps in analyzing symptomatic, as well as incidental adrenal lesions with high sensitivity and specificity.
Aim This study was conducted to determine the cytological spectrum of adrenal lesions in a tertiary care center.
Material and Methods This was a retrospective study which included a total of 19 cases of adrenal FNAC received from June 2017 till June 2019 in a north Indian tertiary care university hospital. All the lesions were broadly classified into non-neoplastic and neoplastic categories. The non-neoplastic lesions were divided into infective causes and cystic lesions. Neoplastic lesions were further grouped into benign and malignant lesions. Immunohistochemical findings were retrieved from the hospital records wherever accessible.
Results A total of 19 cases were aspirated, of which 16 cases (84.20%) yielded satisfactory material. Six cases (31.57%) showed non-neoplastic pathology of which one was a cystic lesion, three were infective (two histoplasmosis and one tuberculosis), and two showed only benign adrenal cortical cells in a setting of known extra-adrenal primary malignancy. The neoplastic group comprised of 10 cases (52.63%) of which 4 cases showed metastatic carcinomatous deposits from a known extra-adrenal primary malignancy and 6 cases showed primary adrenal neoplasm (one case of myelolipoma, one case of pheochromocytoma, and four cases of adrenal neoplasm) which were then subjected to biopsy and immunohistochemistry. A final diagnosis of pheochromocytoma was made in three cases, adrenocortical carcinoma in one case, and one case was inconclusive because of nonrepresentative biopsy.
Conclusion Image-guided fine-needle aspiration cytology of adrenal lesions helps to determine the exact nature of the infection, avoids unnecessary surgery, and helps in targeted management. However, histopathological evaluation with immunohistochemistry remains the diagnostic modality of choice with regard to neoplastic lesions.

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
Protozoan parasites with complex life cycles have high mortality rates affecting billions of human lives. Available anti-parasitic drugs are inadequate due to variable efficacy, toxicity, poor patient compliance and drug-resistance. Hence, there is an urgent need for the development of safer and better chemotherapeutics. Mitogen Activated Protein Kinases (MAPKs) have drawn much attention as potential drug targets. This review summarizes unique structural and functional features of MAP kinases and their possible role in pathogenesis of obligate intracellular protozoan parasites namely, Leishmania, Trypanosoma, Plasmodium and Toxoplasma. It also provides an overview of available knowledge concerning the target proteins of parasite MAPKs and the need to understand and unravel unknown interaction network(s) of MAPK(s).

Abstract
Rice false smut (RFS), an emerging major fungal disease worldwide caused by Ustilaginoidea virens, affects rice grain quality and yield. RFS cause 2.8-49% global yield loss depending upon disease severity and cultivars. In India, the yield loss due to RFS ranged from 2 to 75%. Identification of the genes or quantitative trait loci (QTLs) governing disease resistance would be of utmost importance towards mitigating the economic losses incurred due to RFS. Here, we report mapping of RFS resistance QTLs from a resistant breeding line RYT2668. The mapping population was evaluated for RFS resistance under the field condition in three cropping seasons 2013, 2015, and 2016. A positive correlation among infected panicle/plant, total smut ball/panicle, and disease score was observed in the years 2013, 2015, and the mean data. A total of seven QTLs were mapped on rice chromosomes 2, 4, 5, 7, and 9 using 2326 single nucleotide polymorphism markers. Of these, two QTLs, qRFSr5.3 and qRFSr7.1a, were associated with the infected panicle per plant, one QTL qRFsr9.1 with total smut ball per panicle, and four QTLs qRFSr2.2, qRFSr4.3, qRFSr5.4, and qRFSr7.1b with disease score. Among them, a novel QTL qRFSr9.1 on chromosome 9 exhibits the largest phenotypic effect. The prediction of putative candidate genes within the qRFSr9.1 revealed four nucleotide-binding sites-leucine-rich repeat (NBS-LRR) domain-containing disease resistance proteins. In summary, our findings mark the hotspot region of rice chromosomes carrying genes/QTLs for resistance to the RFS disease.

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
Decarboxylative A3-coupling of ortho-hydroxybenzaldehydes, secondary amines, and alkynoic acids is performed under catalyst and solvent-free conditions. The developed methodology provided a waste-free method for the synthesis of hydroxylated propargylamines which are versatile precursors for various bioactive heterocyclic scaffolds. The experimental and density functional theory studies revealed that the in situ-formed ortho-quinonoid intermediate (formed from ortho-hydroxybenzaldehyde and amine) undergoes a concerted Eschweiler-Clarke type decarboxylation with alkynoic acids. The synthesized compounds were evaluated for MAO-A, MAO-B, and AChE inhibitory activities as potential drug candidates for the treatment of various neurological disorders. Compound 4f was found to be the most potent and selective MAO-B (high selectivity over MAO-A) and AChE inhibitor in the series with IC50 values of 4.27 ± 0.07 and 0.79 ± 0.03 μM, respectively.

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
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
It is shown that water-in-oil microemulsions (m/e or μE) can produce BaCeO3 (BCO) and LaCoO3 (LCO) precursors. The nanoparticles (NPs) adsorb on AlOOH sols, in much the same way as Turkevich previously immobilised platinum group metal sols. BCO is active in CO and propane oxidation and NO removal under stoichiometric exhaust conditions, but LCO is a better oxidation catalyst. Activity was also seen when Ba,Ce and La,Co are inserted into/segregate at the surface of AlOOH/Al2O3. However, there is only formation of low levels of BCO, CAIO3 (CAO), LCO and LaAIO3 (LAO) perovskites, along with aluminates and separate oxides. The complexing of cations by AlOOH surface-held oxalate ions, albeit with different efficiencies, has also been explored. All three routes yield active catalysts with micro-domains of crystallinity; microemulsions produce the best defined perovskite NPs, but even those from surface segregation have higher turnover numbers than traditional Pt catalysts. Perovskite NPs may open up green chemistry for air pollution control that is consistent with a circular economy.

Abstract
Biosimilars are highly similar versions of approved branded biologics. In contrast to generics, which are identical copies of the originator medicines, biosimilars are considered unique but related molecules that differ from the originator reference product as well as from each other. Owing to the complexity of biologic medicines, such as therapeutic monoclonal antibodies, minor differences between biosimilars and the reference products are acceptable provided these differences do not result in any clinically meaningful differences in safety or efficacy. In addition, minor changes in structure and function may occur over time in originator biologic products as a result of alterations in production materials (e.g. cell lines), processes or conditions. The developmental process for biosimilars focuses on a 'totality of evidence' approach that emphasizes a stepwise investigational process, including comprehensive structural, functional, pharmacologic and clinical assessment for similarity. The goal of the phase 3 clinical development programme for a biosimilar is not to establish efficacy, per se, but to demonstrate that there are no clinically meaningful differences between the proposed biosimilar and the reference product. The requirement to show clinical similarity informs biosimilar study design, including the selection of the patient population, disease state (indication), study endpoints and statistical methods. Based on the clinical trial results in a representative patient population, results may be extrapolated to other indications provided scientific justification is demonstrated based on, among other things, similar mechanism of action in the extrapolated indications. This review presents the current state of knowledge with respect to biosimilars. We aim to provide the practising clinician with a working knowledge of biosimilars as well as provide some practical guidance on their use and potential benefits in treating dermatologic diseases.

Abstract
Abstract
Background: Metastatic breast cancer (MBC) and the circulating cells (CTCs) leading to macrometastasis are inherently different than primary breast cancer, evolving under the selection pressure of systemic therapy. A better understanding of the tumor biology of CTCs compared to metastasis may shed light on treatment opportunities.
Methods: We performed whole transcriptome sequencing (RNA Seq) on fresh metastatic tumor biopsies (mets), CTCs, and peripheral blood (PB) from 21 newly diagnosed MBC patients. CTCs were harvested using the ANGLE Parsortix to isolate cells based on size and deformability. Data were analyzed for differential expression, pathways, single nucleotide variants (SNV), fusions, intrinsic subtype, and a CTC-mets shared gene signature was validated using data from The Cancer Genome Atlas (TCGA). Detailed clinical-pathological and treatment data was evaluated.
Results: CTCs as a group showed much stronger gene expression of oncogenes, stem cell genes, keratins and mesenchymal markers than did mets from the same patients. Matched patient comparisons for 66 potentially clinically actionable genes for 8/9 pathways showed no significant difference in gene expression targets between CTCs and mets on ANOVA, although fold-change did vary. Eight SNVs in the ESR1 gene (n=5 patients) and 5 SNVs in the HER2 gene (n=2 patients) were shared between CTCs and distant metastases.
Differential gene expression analysis identified a signature of 8870 genes that were statistically significantly correlated between CTCs and mets (FDR adjusted p<0.05). Ingenuity pathway analysis was applied to the list of genes shared between CTCs and mets, with analysis of canonical pathways and upstream regulators revealing numerous oncogenes and breast cancer related genes. The top upstream regulators of CTCs-mets were beta-estradiol, progesterone, FOXA1, HNRPA2B1 and HNF1A. The top 50 genes of this CTC-mets shared signature were prognostic of worse overall survival in the TCGA breast cancer dataset (p<0.001), which included 817 patients with a median follow-up of 59.5 months. Second time-point data for n=5 patients with subsequent PB draws 6 months after baseline is currently pending. Intrinsic subtyping of mets by either NanoString assays or RNA Seq were not concordant with intrinsic subtyping of CTCs by RNA Seq.
Four of 21 CTC samples showed strong whole transcriptome RPKM correlation with PB (R2)>0.9, however, 3/21 CTC samples showed strong whole transcriptome RPKM correlation with mets (R2)>0.8. The remainder showed low correlation with both. Coverage was 91.4X for CTCs, 140.2X for mets and 138.5X for PB.
Conclusions: We present the transcriptomic landscape of CTCs with comparison to metastases and peripheral blood all acquired prior to treatment of newly diagnosed Stage IV breast cancer. Multiple genes, including oncogenes and stem cell genes, were found with higher expression in CTCs versus metastases. When focusing on 66 known potentially clinically actionable genes in breast cancer, CTCs did not show significantly different patterns of expression than mets in terms of up-regulation versus down-regulation compared to PB. RNA Seq of CTCs may be utilized to identify molecular alterations that are potentially clinically actionable.

Abstract
Cervical cancer is one of the most common neoplastic diseases affecting women, with a worldwide incidence of almost half a million cases. A history of smoking and use of oral contraceptives have been confirmed to be risk factors for cervical cancer. Genetic susceptibility and immune response, especially impaired cellular immune response, may well be related to the development of cervical cancer. NBS1 is one of the key proteins participating in the recognition and repair of double-strand breaks that may lead to genomic instability and cancer if unrepaired. The objective of the present study was therefore to investigate NBS1 Glu185Gln gene polymorphisms and the risk of cervix cancer in a northern Indian population. We found that passive smokers having particular NBS1 genotypes (Glu/Gln, Gln/Gln or Glu/Gln + Gln/Gln) have an increased risk of developing cervix cancer (OR 5.21, p=0.000001; OR 4.60, p=0.001; OR 5.10, p=0.0000009, respectively). The risk was increased 2.4-fold in oral contraceptive users with a Glu/Gln genotype. We conclude that the risk of cervical cancer is increased in passive smokers and in users of oral contraceptives with certain NBS1 genotypes.
