Abstract
The current article presents a huge enhancement in the field emission characteristics of zinc oxide (ZnO) micro/nanorods by nickel doping. The synthesis of pure and nickel-doped zinc oxide (ZnO) micro/nanorods was done by a simple low-temperature chemical method. Both the as-prepared pure and doped samples were analyzed by X-ray diffraction and electron microscopy to confirm the proper phase formation and the developed microstructure. UV-vis transmittance spectra helped in determining the band gap of the samples. Fourier-Transform Infrared Spectroscopy (FTIR) spectra showed the different bonds present in the sample, whereas X-ray Photoelectron Spectroscopy (XPS) confirmed the presence of nickel in the doped sample. Photoluminescence (PL) spectra showed that after doping, the band-to-band transition was affected, whereas defect-induced transition had increased significantly. After the nickel doping, contact angle measurement revealed a significant decrease in the sample's surface energy, leading to a remarkably high water contact angle (within the superhydrophobic region). Simulation through ANSYS suggested that the doped sample has the potential to function as an efficient cold emitter, which was also verified experimentally. The cold emission characteristics of the doped sample showed a significant improvement, with the turn-on field (corresponding to J = 1 μA cm-2) reduced from 5.34 to 2.84 V μm-1. The enhancement factor for the doped sample reached 3426, approximately 1.5 times higher compared to pure ZnO. Efforts have been made to explain the results, given the favorable band bending as well as the increased number of effective emission sites.

Abstract
BACKGROUND AND OBJECTIVES: With an increased demand for rapid, diagnostic tools for TB and drug resistance detection, Truenat® MTB-RIF assay has proven to be a rapid point of care molecular test. The present study aimed to establish a proof of concept of using Trueprep-extracted DNA for line-probe assay (LPA) testing.METHODS: A total of 150 sputum samples (MTB-positive at Truenat sites) were divided into two aliquots. One aliquot was used for DNA extraction using the Trueprep device and MTB testing. The second aliquot of the sample was subjected to GenoLyse® DNA extraction. DNA from both the Trueprep and GenoLyse methods was subjected to first-line (FL) and second-line (SL) LPA testing.RESULTS: Of 139 Trueprep-extracted DNA, respectively 135 (97%) and 105 (75%) had interpretable results by FL and SL-LPA testing. Of 128 GenoLyse-extracted DNA, all 128 (100%) had interpretable FL-LPA results and 114 (89%) had interpretable SL-LPA results.CONCLUSION: The results obtained in this study indicate that Trueprep-extracted DNA can be used in obtaining valid LPA results. However, the study needs to be conducted on a larger sample size before our recommendations can be used for policy-making decisions.

Abstract
Introduction Paddy leaf diseases have a catastrophic influence on the quality and quantity of paddy grain production. The detection and identification of the intensity of various paddy infections are critical for high-quality crop production. Methods In this paper, infections in paddy leaves are considered for the identification of illness severity. The dataset contains both primary and secondary data. The four online repositories used for secondary data resources are Mendeley, GitHub, Kaggle and UCI. The size of the dataset is 4,068 images. The dataset is first pre-processed using ImageDataGenerator. Then, a generative adversarial network (GAN) is used to increase the dataset size exponentially. The disease severity calculation for the infected leaf is performed using a number of segmentation methods. To determine paddy infection, a deep learning-based hybrid approach is proposed that combines the capabilities of a convolutional neural network (CNN) and support vector machine (SVM). The severity levels are determined with the assistance of a domain expert. Four degrees of disease severity (mild, moderate, severe, and profound) are considered. Results Three infections are considered in the categorization of paddy leaf diseases: bacterial blight, blast, and leaf smut. The model predicted the paddy disease type and intensity with a 98.43% correctness rate. The loss rate is 41.25%. Discussion The findings show that the proposed method is reliable and effective for identifying the four levels of severity of bacterial blight, blast, and leaf smut infections in paddy crops. The proposed model performed better than the existing CNN and SVM classification models.

Abstract
Cloud computing plays an important role in every IT sector. Many tech giants such as Google, Microsoft, and Facebook as deploying their data centres around the world to provide computation and storage services. The customers either submit their job directly or they take the help of the brokers for the submission of the jobs to the cloud centres. The preliminary aim is to reduce the overall power consumption which was ignored in the early days of cloud development. This was due to the performance expectations from cloud servers as they were supposed to provide all the services through their services layers IaaS, PaaS, and SaaS. As time passed and researchers came up with new terminologies and algorithmic architecture for the reduction of power consumption and sustainability, other algorithmic anarchies were also introduced, such as statistical oriented learning and bioinspired algorithms. In this paper, an indepth focus has been done on multiple approaches for migration among virtual machines and find out various issues among existing approaches. The proposed work utilizes elastic scheduling inspired by the smart elastic scheduling algorithm (SESA) to develop a more energy-efficient VM allocation and migration algorithm. The proposed work uses cosine similarity and bandwidth utilization as additional utilities to improve the current performance in terms of QoS. The proposed work is evaluated for overall power consumption and service level agreement violation (SLA-V) and is compared with related state of art techniques. A proposed algorithm is also presented in order to solve problems found during the survey.

Abstract
Background Pheochromocytoma, the great masquerader, can have a varied spectrum of clinical manifestations. It can often cause a diagnostic challenge despite the availability of modern investigation modalities. Case We present the case of a 38-year-old male who presented with uncontrolled hypertension for the past 10 years and heart failure for one year. The diagnosis of pheochromocytoma was missed in the initial setting, leading to a biopsy of the retroperitoneal mass. Fortunately, the patient survived the procedure. Subsequently, with the involvement of a multi-disciplinary team, he was optimized for surgery under strict cardiac monitoring. After the complete excision of the tumour, he showed significant improvement not only in his clinical symptoms but also in his cardiac status. Conclusions This case emphasizes the age-old medical phrase of 'Primum non nocere or first, do no harm'. Any invasive procedure in a pheochromocytoma can lead to a massive release of catecholamines causing a hypertensive crisis, pulmonary oedema, and even cardiac arrest. Any young patient presenting with hypertension or heart failure should be investigated for secondary causes. Cardiomyopathy due to pheochromocytoma is because of catecholamine overload and usually reverses or improves after curative surgery.

Abstract
In the satellite data era starting from 1979, the extent of Antarctic sea ice increased moderately for the first 37 years. However, the extent decreased to record low levels from 2016 to 2020, with the drop being greatest in the Weddell and Lazarev Seas of the Southern Ocean. An important question for the scientific fraternity and policymakers is to understand what ocean-atmospheric processes triggered such a rapid decline in sea ice. We employ in-situ, satellite, and atmospheric reanalysis data to examine the causative mechanism of anomalous sea ice variability in the Lazarev Sea at a time of ice growth in the annual cycle (March-April 2019), when a cargo ship was stuck in extensive ice cover and freed following the unusual decline in sea ice. High-resolution Sentinel-1 synthetic aperture radar captured a distinct view of the ship location and track within extensive ice cover of fast sea ice, dense pack ice, and icebergs in the Lazarev Sea on 27 March 2019. Subsequently, the sea ice cover declined and reached the fourth lowest extent in the entire satellite record during April 2019 which was 25.6% lower than the long-term mean value of 2.65 × 106 km2. We show that the anomalous sea ice variability was due to the occurrence of eastward-moving polar cyclones, including a quasi-stationary explosive development that impacted sea ice through extreme changes in ocean-atmospheric conditions. The cyclone-induced dynamic (poleward propagation of ocean waves and ice motion) and thermodynamic (heat and moisture plumes from midlatitudes, ocean mixed layer warming) processes coupled with high tides provided a conducive environment for an exceptional decline in sea ice over the region of ship movement.

Abstract
Glanders, caused by a bacterium called B. mallei, is primarily an infectious horse and human disease. Although its incidence is rare in developed countries, it is nonetheless prevalent in several geographical areas of the world. There is a lack of cost-effective, rapid and specific molecular typing tools for epidemiological tracing of glanders cases. We previously reported an SNP-based typing method that categorizes global B. mallei strains into three lineages (L1 to L3), as well as additional branches, sub-branches and groups. However, further discrimination of the Indian and Pakistani isolates within the L2B2sB2 sub-branch was not possible due to the lack of sufficient epidemiological markers. In this study, 10 B. mallei strains isolated from four states in India during 2015-2016 were whole genome sequenced; SNP analysis further confirmed their position in the L2B2sB2 branch. To better track the strains, four new markers targeting Indian or Pakistani strains, and specifically targeting sub-groups within the Indian strains, were identified. The new SNP markers were tested and validated on the 10 Indian isolates included in this study as well as on 6 contemporary B. mallei Pakistani strains. These rapid and discriminating typing tools will contribute to the epidemiological monitoring of B. mallei infections, particularly in South Asia and the Middle East, endemic regions of the disease.

Abstract
The growth factors platelet derived growth factor (PDGF), transforming growth factor alpha (TGF-α) and transforming growth factor beta (TGF-β) have been demonstrated to stimulate the in vitro proliferation of theca and granulosa cells in different animals. The present study was conducted to localise the growth factors PDGF, TGF-α and TGF-β in different types of interstitial cells and stromal cells of normal cycling goat ovaries. Tissue fixed in formalin was processed through a graded series of alcohols and embedded in paraffin wax. The sections were immunohistochemically stained with antibodies against PDGF, TGF-α and TGF-β. The binding affinity of interstitial cells and stromal cells were observed and photographed. The staining pattern of PDGF, TGF-α and TGF-β was mild to strong in stromal cells. The primary and secondary interstitial cells exhibited varied staining patterns for all studied growth factors. These findings in goat suggests that PDGF, TGF-α, TGF-β were potentially an important autocrine regulator of different cell functions and possibly a paracrine regulator of ovarian cell function at various development stages.

Abstract
Mastitis and metritis are two inflammatory diseases with high economic impact on dairy industry and farmers are losing revenues. Antibiotic treatment for these disease conditions typically achieve suboptimal outcomes. Moreover, emerging antibiotic resistance in mastitis and metritis worldwide has a severe effect on productivity, fertility, and lifespan of animals. A paradigm shift in treatment strategies is much needed for these animals. Attracting properties of mesenchymal stem cells may act as an alternative strategy for treating these diseases. In addition to their ability to differentiate into multiple types of cells, mesenchymal stem cells can orchestrate immune responses and modulate tissue microenvironments. In the present study, we evaluated the safety and efficacy of adipose tissue–derived mesenchymal stem cells (AT-MSC) for mastitis and metritis. A well-characterised adipose-derived stem cell line with 3–5 passages cells were used for treatment for these diseases. In a safety trial, mastitis- and metritis-infected cattle were administered with 1×106 cells of AT-MSC through different routes (local, IV, IV+local). Animals were clinically evaluated during 15 days of the experimental period and blood samples were collected for hemogram determination. The efficacy was checked under both invivo and invitro conditions. Invitro efficiency of AT-MSC was determined using a transwell plate experiment, in which AT-MSC were co-cultured with bacteria (Escherichia coli and Staphylococcus). Invivo efficiency was evaluated by administration of in 2mL (1×106 cells) of AT-MSC dose; then, somatic cell count (SCC) in milk of mastitic cattle and polymorphonuclear (PMN) cell count in cervical vaginal fluid (CVF) of metritic cattle were determined. Gene expression profiling of antimicrobial (cathelicidin, lipocalin, cystatin) and anti-inflammatory (IL-4, IL-6, IL-10) peptides were quantified in all groups: IV, local, IV+local, and control ATB (antibiotic). Allogenic AT-MSC did not induce any immunological rejection response in treated animals. A significant reduction of bacteria in CVF invitro when co-cultured with AT-MSC was observed. The PMN count was significantly reduced in CVF of the IV+local group. The SCC in milk of mastitic animals was decreased in the local (intramammary) group. Maximum expression of IL-6, IL-10, cathelicidin, lipocalin, and cystatin and angiopoietin genes were observed on Day 3 followed by Day 7 in the local group in case of mastitis. In metritis, expression of IL-6, IL-10, cathelicidin, lipocalin, cystatin, and angiopoietin were observed at Day 3 in the IV+local group. All mastitic and metritic cattle were completely and permanently cured within 30 days after treatment with mesenchymal stem cells. In conclusion, we provide initial evidence for the use of allogenic AT-MSC and their safety and efficacy to treat mastitis and metritis in dairy cattle.

Abstract
Axillary lymph node involvement is a very important poor prognostic factor in the clinical staging and management of breast cancer patients. Traditionally, axillary lymph node dissection (ALND) has been used for determining the status of the axillary lymph nodes. More recently the sentinel lymph node biopsy (SLNB) procedure has gained wider acceptance as the standard of care, having the advantage of being less invasivewhile providing good accuracy. This expert group used data from published literature, practical experience and opinion of a large group of academic oncologists to arrive at these practical consensus recommendations in regards with the use of the two different procedures and other issues in patients with early breast cancer for the benefit of community oncologists.

Abstract
Abstract
Next-generation sequencing (NGS) technologies have provided affordable but errorful ways to generate raw genetic data. To extract variant information from billions of NGS reads is still a daunting task which involves various hand-crafted and parameterized statistical tools. Here we propose a deep neural networks (DNN) based alignment and single nucleotide variant (SNV) identifier tool known as DAVI: deep alignment and variant identification. DAVI consists of models for both global and local alignment and for variant calling. We have evaluated the performance of DAVI against existing state-of-the-art tool sets and found that its accuracy and performance is comparable to existing tools used for bench-marking. We further demonstrate that while existing tools are based on data generated from a specific sequencing technology, the models proposed in DAVI are generic and can be used across different NGS technologies as well as across different species. The use of DAVI will therefore help non-human sequencing projects to benefit from the wealth of human ground truth data. Moreover, this approach is a migration from expert-driven statistical models to generic, automated, self-learning models.

Abstract
Periconceptional folic acid is known to have a major role in the prevention of neural tube defects, leading to global recommendations for folic acid supplementation before and in early pregnancy. Maternal folate throughout pregnancy may have other roles in offspring health, including neurodevelopment and cognitive performance in childhood. Folate and folic acid (vitamin B9) act as a co-enzyme essential for single carbon metabolism, a network of pathways involved in several biological processes including nucleotide synthesis, DNA repair, and methylation reactions. In general, rapidly growing and multiplying cells require an adequate supply of folate. A primary deficiency of natural folate resulting in an increase of the total homocysteine concentration may be detrimental to the quality of the oocyte, subsequent fertilisation, embryogenesis, implantation, and fetal development. However, to date, folate-methionine metabolism and folate transport have not been studied in developing buffalo embryos. The present study details transcript expression for genes encoding key enzymes in the linked folate-methionine cycles in the ovary tissue, cumulus cells, immature oocytes, IVM oocytes, and pre-implantation embryos and also estimates the folate concentration in follicular fluid (FF) of buffalo. The FF was pooled and collected by aspiration of different sizes of surface follicles (2-8mm diameter). The total number of analysed samples was three, with different dilutions and estimation of folate in FF of buffalo done by chemiluminescence assay. Total RNA was extracted from oocytes, cumulus cells, ovarian tissue, and embryos produced from IVF. RT-PCR was performed to analyse the expression of folate-methionine cycle enzymes and folate transporters. Transcripts for all the enzymes of the folate-methionine cycle (i.e. SHMT, MTR, MTRR, MAT1A, MAT2B, GNMT, AHCY, CBS, and DHFR) and folate transporters (FOLR1, FOLR2) and reduced folate carrier (SLC19A1) were expressed in ovarian tissue, cumulus cells, oocytes, and pre-implantation embryos. Immunocytochemical analysis revealed FOLR2 and SLC19A1 protein expression on the plasma membrane and/or cytoplasm of the oocytes and embryos, and FOLR1 in the nucleus of pre-implantation embryos. The folate concentration in FF was 24ngmL−1. This is the first report to examine the concentration of folate in FF and revealed the identification of transcripts in different samples of buffalo species. The presence of these enzymes could have a profound effect on single-carbon metabolism within the ovary and pre-implantation embryo, therefore indicating that folate from FF is being disseminated through folate receptors within oocytes and embryos to participate in the folate pathway. This study advocates the necessity for examination of the result of folate supplementation throughout invitro embryo production for improving the quality and quantity of transferable blastocysts and subsequently live calf births in buffalo.

Abstract
The present study was carried out to isolate mesenchymal stem cells (MSCs) from adipose tissue of cattle (Bos indicus), characterise them, and apply them for the treatment of mastitis and metritis in the cow. Cattle MSCs were isolated from adipose tissue near the loin region of cow. Isolated adipose tissue was subjected to enzymatic digestion using 2% collagenase with agitation at regular intervals. The cells obtained after digestion were resuspended in cell culture flasks containing growth enriched medium and cultured under standard culture conditions. Alkaline phosphatase staining was used as one of the parameters to confirm cultured putative MSCs. Bovine Ad-MSCs were further characterised using real time-PCR by amplification of MSC-specific markers: CD73, CD90, and CD105 as positive markers and CD34, CD45, and CD79a as negative markers. Immunocytochemistry showed the presence of CD73, CD90, and CD105 on the cell surface. Three groups-control (C), local (L), and intravenous (IV)-with 6 cows suffering from mastitis were taken in each group and subjected to MSC transplantation through local and intravenous routes. Control group animals were subjected to antibiotic treatment only. Similarly, another three groups were taken with 6 cows in each group suffering from metritis. Post-transplantation wound healing, tissue repair, and reduction in inflammation were monitored for 26 days, at different time intervals; that is, after Days 1, 3, 7, and 15. Blood samples were also collected from animals at the same time intervals for real time-PCR. A similar examination was also done in metritis groups along with the analysis of the reduction in turbidity of cervical fluid at the abovementioned time intervals. Real time-PCR was performed to determine relative expression of genes for proliferative factors, anti-inflammatory cytokines, and antimicrobial peptides on cells isolated from blood collected at different time intervals. Gene expression in the local group of mastitis subjected to MSC injection was significantly higher than that of the IV and control group. The somatic cell count declined in both local and IV groups compared with the control group. Whereas the expression of the same genes in the IV group of metritis was significantly higher than that of the local and control groups of cows. The turbidity of cervical fluid and mucus was reduced in the IV group compared with the local group. In conclusion, we demonstrated the healing potential of MSCs in a cow model via MSC injection. Promising results were obtained in curing mastitis in both local and IV groups, whereas healing in the case of metritis was significantly higher in the IV group compared with both the control and local groups of cows. The study indicates the potential use of MSc for treatment of mastitis and metritis in cattle through wound healing and decreasing microbial infection.

Abstract
BACKGROUND The results of trans-sphenoidal surgery (TSS) in Cushing's disease (CD) vary widely depending upon patient characteristics as well as surgical experience. Patients in India are often referred late to referral centers. We studied the rates of remission and endocrine deficiencies after TSS in patients with CD presenting to a referral hospital in India. METHODS Sixty consecutive patients (45 females, median age 24.5 years) who underwent TSS between 2000 and 2015 were studied. The median (range) duration of follow-up was 40 (3-138) months. Initial and long-term remission and relapse rates and pituitary hypofunction post-TSS were evaluated. RESULTS Eighteen (30%) patients harbored macroadenomas. Twenty-eight (47%) patients achieved remission in the immediate post-operative period (8 AM serum cortisol < 140 nmol/l), while a higher remission rate was noted at 6 months (39/54 patients, 72%). At 1 year 70% patients and at final follow-up [median duration 40 (range 3-138) months], 58% of patients were in remission. No pre- or post-surgical variables were consistently associated with remission, except for the 8-AM serum cortisol level on the fifth day after surgery. Seven (18%) patients relapsed on follow-up, including five patients who had fifth post-operative day 8 AM serum cortisol < 140 nmol/l. Twelve (25%) patients newly developed hypothyroidism and one (1.6%) patient developed amenorrhoea after TSS. CONCLUSION Remission rate at 6 months was higher than immediately after TSS. A significant proportion of patients relapsed, thus necessitating life-long follow-up. New-onset hypothyroidism was frequent after TSS.

Abstract
Among stem cells, mesenchymal stem cells (MSC) are best suited for therapeutic purposes because of their immunomodulatory properties, ability to be isolated from adult animal at any stage, ease of propagation in the laboratory, and so on. The present study was carried out to isolate and characterise MSC from adipose tissue of mouse (Mus musculus), and to test their application for the treatment of fractured tibia bone in mouse. Cattle and buffalo MSC, already cultured and characterised in our laboratory, were used in the present study as xenogeneic MSC to observe the healing in mouse model. Murine Ad-MSC were isolated from mouse inguinal fat pad by enzymatic digestion method and cultured in growth enriching medium in standard culture conditions. To test the therapeutic potential of MSC, 24 mice were divided into 4 groups: control (C), allogeneic (A), cattle xenogeneic (CX), and buffalo xenogeneic (BX) with 6 mice (having tibial bone mechanical fractured) in each group, and had the corresponding MSC cells injected in the fracture area. The control group was not subjected to any kind of MSC treatment. Post-treatment, healing in all groups was examined for 36 days at different intervals (Days 1, 12, 24, and 36) via digital X-ray imaging. A bone healing score was assigned to each mouse per the protocol provided by RUST (Radiographic Union Scale in Tibial bone) fractures. The results of present study showed that murine Ad-MSC were positive for MSC-specific markers CD44, CD90, CD105, and negative for CD34 and CD45 via RT-PCR and immunocytochemistry. The Ad-MSC were also positive for the alkaline phosphatase staining. Statistical analysis, using Proc GLM (SAS Institute Inc., Cary, NC, USA), revealed that the bone healing was significantly different (P < 0.01) between group C (1.708 ± 0.059) and other groups [group A (2.125 ± 0.061), CX (2.167 ± 0.068), BX (2.250 ± 0.068)], suggesting that healing was greater in groups transplanted with MSC compared with control. However, healing between groups transplanted with MSC (A, CX, and BX) was not significantly different (P > 0.05). In conclusion, we have observed the healing potential of MSC in mouse model via allogeneic and xenogeneic MSC transplantation; the healing potential among the A, CX, and BX MSC groups was similar.

Abstract
Folic acid (vitamin B9) is the principal component of one-carbon (C1) metabolism in mammalian cells. It acts as a coenzyme in C1 unit transfer during nucleotide and amino acid metabolism. Therefore, it is unquestionably essential for the formation of thymidylate (TMP) for DNA synthesis and methylation, which is in turn crucial for post-implantation embryonic brain and nerve chord development. However, the role of folic acid in maturation of oocytes and subsequent blastocyst production is largely ambiguous in different mammalian species. The aim of this study was to investigate the effect of folic acid supplementation on expression of oocyte maturation markers and folate cycle enzymes in cumulus cells in addition to blastocyst development rate in goat. Immature oocytes were isolated from ovaries, and 1600 oocytes were matured in maturation medium (medium-199) supplemented with 0 (control), 50, 100, or 150 µM folic acid (Sigma Aldrich, India), comprising total 400 oocytes in each group in 5 replicates. The oocytes were in vitro fertilized and embryos were cultured for 7 days. Blastocyst rate was calculated in all 4 groups. Cumulus cells from matured oocytes from each group were analysed for the differential expression of oocyte maturation markers: PTX3, PTGS2, CTSB, and CTSS, and folate cycle enzyme transcripts MTR, MAT2A, ACHY, DHFR, and SLC19A1, by qRT-PCR. For statistical analysis, one-way ANOVA was used. The results of present study show that blastocyst rate was significantly higher (P ≤ 0.05) at 50 µM folic acid (21.4 ± 1.2%) compared with control (13.6 ± 0.4%), 100 µM (10.4 ± 0.34%), and 150 µM (7.4 ± 0.54%). However, there was no effect on the number of cleaved embryos among control (72 ± 0.21%), 50 µM (70.6 ± 0.58%), 100 µM (73.75 ± 0.31%), and 150 µM (73.02 ± 0.04%). The expression of the oocyte maturation markers PTX3 and PTGS2 was up-regulated, whereas that of CTSS and CTSSB was down-regulated (P ≤ 0.05), in the 50 µM group, but did not change (P ≤ 0.05) among the other groups. The expression of these genes did not change significantly among the other groups. The expression of genes of the folate cycle, MTR, MAT2A, ACHY, and DHFR, increased (P ≤ 0.05) by 5.7-, 3.6-, 2.2-, and 1.7-fold, respectively, at 50 µM, but did not change (P ≤ 0.05) among the other groups. The expression of SLC19A1 did not change significantly among all the groups. The results of present study show that the supplementation of 50 µM folic acid to the maturation medium results in increased maturation of oocytes, making them more competent for the blastocyst development. Up-regulation of transcripts of folate cycle enzymes at 50 µM might explain the increase in the blastocyst production rate, which further needs to be validated.

Abstract
Spermatogonial stem cells (SSC) form the basis of spermatogenesis and continuous fertility in male. Their meagre population in the testis is a hindrance in the in vitro study of biological activity of these cells. The objective of the present study was to isolate and characterise goat SSC and increase their number during in vitro culture by different methods. Two goat testes (3 to 4 months of age) were collected from the slaughterhouse and transported to the laboratory. The testes were washed and seminiferous tubules were collected and minced in the laminar flow hood. The seminiferous tubules were washed twice with PBS to remove spermatozoa and subjected to double enzymatic digestion (collagenase, 1 mg mL−1, hyaluronidase, 1 mg mL−1, trypsin, 0.05%, and DNaseI, 10 µg mL−1 for 45 min and second digestion with same set of enzymes except trypsin for 30 min). The isolated cells were filtered sequentially through nylon mesh filters of pore size 70 and 40 µm. The cells were plated on DSA-lectin coated dishes for 4 h and the unattached cells were cultured on a Sertoli cell feeder layer prepared by treating with mitomycin-C for 3 h. The cells were cultured in DMEM/F-12 supplemented with human recombinant growth factors (glial cell-derived neurotrpic factor, 10 ng mL−1, fibroblast growth factor FGF, 10 ng mL−1, epidermal growth factor, 20 ng mL−1), 10% fetal bovine serum, and antibiotics. The expression of pluripotency markers (Oct4, Nanog, Sox2) and SSC-specific markers (Thy1, GfrA1, and Uchl1) in the SSC colonies was determined by RT-PCR and immunostaining, after in vitro culture of 3 weeks. The SSC population was enhanced by differential plating, Percoll density gradient (on Day 1) and SSC passaging (by passaging SSC colonies on Day 20). The cells were tagged with GfrA1 antibody and their population was tested by flow cytometry. The SSC colonies started appearing after 7 days and continued to grow in size and number until 3 weeks. The SSC colonies were positive for the pluripotency markers Oct4, Nanog, and Sox2 by RT-PCR and immunostaining. The SSC were also positive for the SSC-specific markers Thy1, GfrA1, and Uchl1 by RT-PCR and immunostaining. Flow cytometry showed that the GfrA1-positive population in the SSC enriched by the differential plating was 11.23%, Percoll density gradient was 23.57%, and by passaging of SSC colonies, after picking and trypsinising with 0.05% trypsin, was 91.23%. In vitro culture of the SSC enriched by these methods also revealed that the number of SSC colonies appearing in the cells enriched by passaging was higher than the other methods. From the results of present study, we conclude that SSC are positive for markers of pluripotency and SSC-specific markers. The SSC population can be enhanced to a very high level following SSC passaging, which is an inexpensive method and does not require expensive instruments like fluorescence- or magnetic-activated cell sorting.

Abstract
INTRODUCTION To audit the survival outcomes and loco-regional control in muscle invasive urinary bladder cancer patients treated with external beam radiation therapy (RT). MATERIALS AND METHODS From November 2008 through December 2011, 50 consecutively diagnosed muscle invasive urinary bladder carcinoma (T2-4a N0-2, M0) patients were included in this retrospective study. All these patients received external beam RT to a median dose of 60 Gy (range 30-66 Gy), and were not suitable for radical surgery due to patients' preference or medical comorbidities. A stepwise procedure using proportional hazard regression was used to identify prognostic factors with respect to survival. RESULTS Completion trans-urethral resection of bladder tumor was done in 38 (76%) patients of the cohort and 47 (94%) had transitional cell carcinoma on histopathology. Clinical stage T2 was diagnosed in 40 (80%) patients. The median follow-up for the entire cohort was 14 ± 8.9 months (range 1-36 months). In conclusion, 24 patients (48%) were free of disease, 5 patients (10%) had residual disease, and 13 patients (26%) had died of disease. Two-year and 3 year overall survival of intact bladder for the entire cohort was 58% and 43.6%, respectively. Cox regression modeling strongly suggested clinical stage (P = 0.01) and RT dose (P = 0.001) as being predictors for overall survival. CONCLUSION RT shows reliable outcomes and excellent compliance in this advanced disease. Prescribing a higher RT dose could potentially correlate to better intact bladder control rates while maintaining good quality of life in selected patients.

Abstract
The influence of Y2O3 nanolayers on thermoelectric performance and structure of 2% Al-doped ZnO (AZO) thin films has been studied. Multilayers based on five 50 nm thick AZO layers alternated with few nanometers thick Y2O3 layers were prepared by pulsed laser deposition on Al2O3 single crystals by alternate ablation of AZO target and Y2O3 target. The number of laser shots on Y2O3 target was maintained very low (5, 10 and 15 pulses in three separate experiments. The main phase (AZO) presents polycrystalline orientation and typical columnar growth not affected by the presence of Y2O3 nanolayers. The multilayer with 15 laser shots of Y2O3 showed best thermoelectric performance with electrical conductivity σ 48 S/cm and Seebeck coefficient S = −82 μV/K, which estimate power factor (S2·σ) about 0.03 × 10−3 W m−1 K−2 at 600 K. The value of thermal conductivity (κ) was found 10.03 W m−1 K−1 at 300 K, which is one third of typical value previously reported for bulk AZO. The figure of merit, ZT = S2·σ·T/κ, is calculated 9.6 × 10−4 at 600 K. These results demonstrated the feasibility of nanoengineered defects insertion for the depression of thermal conductivity.

Abstract
A major genomic alteration in prostate cancer (PCa) is frequent loss of chromosome (chr) 8p with a common region of loss of heterozygosity (LOH) at chr8p22 locus. Genomic studies implicate this locus in the initiation of clinically significant PCa and with progression to metastatic disease. However, the genes within this region have not been fully characterized to date. Here we demonstrate for the first time that a microRNA component of this region –miR-383- is frequently downregulated in prostate cancer, plays a critical role in determining tumor initiating potential and is involved in prostate cancer metastasis via direct regulation of CD44, a ubiquitous marker of PCa tumor initiating cells (TICs)/ stem cells. Expression analyses of miR-383 in PCa clinical tissues established that low miR-383 expression is associated with poor prognosis. Functional data suggests that miR-383 regulates PCa tumor initiating/ stem-like cells via CD44 regulation. Ectopic expression of miR-383 inhibited tumor initiating capacity of CD44+ PCa cells. Also, ‘anti-metastatic’ effects of ectopic miR-383 expression were observed in a PCa experimental metastasis model. In view of our results, we propose that frequent loss of miR-383 at chr8p22 region leads to tumor initiation and prostate cancer metastasis. Thus, we have identified a novel finding that associates a long observed genomic alteration to PCa stemness and metastasis. Our data suggests that restoration of miR-383 expression may be an effective therapeutic modality against PCa. Importantly, we identified miR-383 as a novel PCa tissue diagnostic biomarker with a potential that outperforms that of serum PSA.

Abstract
BACKGROUND Breast reconstruction (BR) plays a significant role in the woman's physical, emotional and psychological recovery from breast cancer. However, the current most accepted methods of reconstruction are expensive, may require microsurgical skills and can be offered to a very small number of patients seeking treatment in tertiary care centers. For the large majority of women seeking treatment in public hospitals, solution lies in finding a method of reconstruction, which is autologous, produces a reasonable match to the contralateral breast in size, shape and symmetry and produces minimal donor site morbidity. It should also be a technique, which is cost effective and can withstand the effects of radiotherapy (RT). The autologous latissimus dorsi (LD) flap is one such versatile technique, which can serve as an ideal reconstructive option for the majority of patients. MATERIALS AND METHODS During a period of 6 years, 19 patients underwent immediate BR using this flap in the Department of General Surgery. Patients who were young (mean age 37.4 years), had small to medium sized breasts, with operable breast cancer (Stage II and IIIa) were selected for the procedure. RESULTS Satisfactory cosmetic results as rated by patients as well as surgeons were achieved in the majority. Donor site morbidities were seroma formation (78%) and donor site wound breakdown (21%). Post-operative RT was well-tolerated by the reconstructed breast. CONCLUSION Autologous LD flap reconstruction is a safe and economical option for BR in low resource settings and is suitable for women with small and medium sized breasts.

Abstract
BACKGROUND In most developing countries, sputum smear microscopy for acid-fast bacilli remains the front line and often the only diagnostic tool for the diagnosis of tuberculosis (TB), making quality assurance of smear microscopy an important activity. OBJECTIVE To evaluate the results of a pilot study, where the random blinded rechecking for the entire state of Delhi was conducted at a reference laboratory. METHODOLOGY Slides from 25 Revised National Tuberculosis Control Programme designated districts (200 peripheral microscopy centres) in Delhi were re-read after proper coding by all the Senior Tuberculosis Laboratory Supervisors (STLS) at an intermediate reference laboratory under proper supervision. RESULTS Of 12,162 re-read slides, 204 discrepant results were found. Of these, 150 (73.5%) errors were attributed to the peripheral microscopy centres and 54 (26.5%) to STLS. High false-positive errors were observed at a frequency of 12/150 (8%), and high false-negative errors at a frequency of 38/150 (25%). Minor errors, i.e., low false-negative, low false-positive and quantification errors, were observed at frequencies of respectively 68/150 (45.3%), 17/150 (11.3%) and 15/150 (10.0%). CONCLUSION Greater stringency in the supervision of random blinded rechecking at the district level is essential to make smear rechecking more efficient and effective.

Abstract
The present study was carried out for isolation and culture of adipose tissue-derived mesenchymal stem cells of goat (gADSC) and dogs (1 dog was suffering from hip dysplasia and another dog from paraplegia) and their characterisation with different markers. Adipose tissue of goat and dog were aseptically isolated and treated with collagenase for 2 h in a CO2 incubator. The enzymatic digested cells were filtered through a 41-µm filter and cells were resuspended in cell culture flask containing medium DMEM/F12, 10% fetal bovine serum, and 50 μg mL–1 gentamycin. In vitro-cultured ADSC were characterised by amplification of mesenchymal stem cell (MSC)-specific surface marker genes of CD44, CD29, and CD166 in PCR and by immunocytochemistry of MSC-specific marker of CD44. For in vitro chondrogenesis, ADSC at passage 3 were incubated in DMEM/F12 containing 100 nM dexamethasone, 1.25 μg mL–1 BSA, and 10 ng mL–1 BMP-4 ITS (insulin-transferrin-selenium) for 3 wk. Chondrogenic differentiation cells were confirmed by Safranin O staining and positive expression of chondrocyte-specific marker genes Aggrecan: primers F-TTGGACTTTGGCAGAATACC and R-CTTCCACCAATGTCGTATCC, and Collagen II: primers F-AACCCTGGAACTGACGGAAT and R-CTCACCCGTTTGACCTTTCG in PCR. Dog ADSC-derived chondrocytes were aseptically injected at 1 × 106 cells kg–1 of BW into dogs with hip dysplasia and paraplegia. Both dogs recovered well after 1 month of autologous transplantation and were able to move freely. Then, 10 dogs having massive wounds were injected with heterologous undifferentiated mesenchymal stem cells at 1 × 106 cells kg–1 of BW and all dogs were cured in an average of 20 days. Then, the paralyzed and fractured dogs were further treated with undifferentiated MSC at 1 × 106 cells kg–1 of BW and most of the dogs were cured properly. These findings may have implications for defining the physiological roles of ADSC in arthritis, some orthopaedic problems, joint regeneration, and neurological disorders and several new applications leading to novel therapeutic opportunities.
