Abstract
The survival rate of pediatric acute myeloid leukemia (pAML) is currently around 60%. While survival has slowly increased over the past few decades, the development of novel agents likely to further improve survival for this heterogeneous patient population has been limited by gaps in the pAML pre-clinical pipeline. One of the major hurdles in evaluating new agents for pAML is the lack of pAML patient-derived xenograft (PDX) models. Unlike solid tumors and other types of leukemias, AML is notoriously hard to establish in mouse models, likely due in part to the need for specific human microenvironment elements. Our laboratory at TCH/BCM addressed this gap by establishing a systematic PDX workflow, leveraging advanced immunodeficient hosts and capitalizing on our high volume of pAML patients and close coordination between labs and clinical sections. Patients treated at TCH are offered the chance to participate in specimen banking protocols that allow blood and bone marrow collection as well as the collection of relevant clinical data. All patients who consent and have samples available are trialed for PDX development. In addition, samples from the Children's Oncology Group (COG) are also trialed for PDX generation. Serially transplanting PDX models are validated using short tandem repeat (STR) and characterized using both targeted DNA/RNA next generation sequencing and RNAseq. As of March 2023, this systematic approach has resulted in 26 serially transplanting models. Models have been shared with requesting labs to facilitate external pAML pre-clinical studies. Available PDX models can be located through the BCM PDX Portal. We expect our growing PDX resource to make a significant contribution to expediting the testing of promising novel therapeutics for pAML.

Abstract
Students serve as ambassadors, conveying effective messages to encourage the adoption of promotes healthy behaviors. Recognizing their consciousness about corona illness 2019 (COVID-19), desires to utilize the COVID-19 vaccines, and other associated variables will aid in developing viable vaccination promotion tactics for the present COVID-19 pandemic. A transverse-segment internet poll of university students in the healthcare and non-healthcare industries was conducted to analyze their motivations to be vaccinated against the coronavirus. To recruit research participants, a random snowball sampling approach was utilized using digital media sites and mails. The contestants were chosen from throughout India, including several main geographic areas, between Nov-2020 and Jan-2021, prior to the release of the COVID-19 vaccination. There were descriptive metrics utilized to illustrate the research participants' socio-demographics and vaccine-related behaviors. Using logistic regression modeling, key characteristics that are expected to influence vaccination uptake among students were modeled. p 0.06 was judged substantial in each study. 656 students participated in the study, with 48.4% coming from the healthcare sector & 51.5% from other fields. Of these 655 students, 43.6 and 22.4% came from India's northern and eastern areas. Graduate students accounted for 41.1% of the total population, and graduates for around 43.2%. The age range of 56.0% of the students was 18 to 25. Women made up 62% of the population, and 69.5% of them were unmarried. Seventy-eight percent of the students were from the medium socioeconomic level. Concerns about side effects and safety, distrust of government officials, and questions about the vaccine's efficacy were among the reasons given by students in this study for their reluctance to get vaccinated. It is essential to remember that these investigations were carried out at various times and in various nations; thus, the conclusions may not apply to all college students throughout the globe. According to the findings of this research, Indian university students showed rather a great deal of motivating desire to acquire COVID-19 immunizations. The people were either doubtful or reluctant to get the vaccination, which suggests possible vaccine aversion. There is a need for information campaigns and other actions to lessen vaccine hesitancy in order to promote the usage of COVID-19 vaccines.

Abstract
Waste Management in India has always been a severe problem, and tackling this issue would require a social mindset towards adopting green practices. This study aims to understand the consumer mindset and awareness of recycling in India and explore factors that could influence India’s recycling behavior. The data for this study has been obtained through a primary research – survey questionnaire. Correlation analysis and regression have been applied to understand the result of the questionnaire data. Promoting recycling amongst people takes into consideration many factors. The results suggest that recycling behavior is mostly influenced by factors, such as willingness to adopt environment-friendly behavior, awareness towards recycling, and providing incentives. This study aimed to explore recycling in India and study the major factors that can influence people to adopt recycling. It also explored a possible relationship between providing incentives and influencing recycling behavior. These findings will help to analyze and develop strategies to boost the recycling rate in India.

Abstract
Abstract
Introduction
Transforaminal Lumbar Interbody Fusion (TLIF) is a technique used for the management of various pathologies such as degenerative disc disease, recurrent disc herniations and spondylolisthesis, to mention the most common indications. There is an ongoing debate regarding the use of open versus minimally invasive techniques for TLIF. Each has its own advantages and disadvantages. In the present study, we aim to present our experience regarding the use of open vs MIS TLIF at Stepping Hill Hospital in Manchester.
Method
A retrospective observational cohort study involving 60 patients was conducted at Stepping Hill Hospital in the UK. Patients who had TLIF surgery between 2019 and 2020 were included. Patients were consecutively allocated to either the open TLIF or the MIS TLIF group. Data were collected from hospital records including pre- and post-operative follow up notes. We also assessed pain score using the visual analogue scale.
Results
26 patients underwent MIS TLIF whereas 34 patients underwent an open procedure. The MIS group showed better outcomes compared to the open group in terms of post-operative complications, improvement of symptoms and the average hospital stay: 7.6% vs 8.8%, 73.7% vs 58.8% and 1.82 vs 2.76 days, however, the open group had a lower rate of metalwork failure 8.8% vs 11.5% in the MIS.
Conclusions
Our study showed that MIS TLIF at our unit seems to result in better outcomes related to symptoms alleviation, post-operative complications and less hospital stay despite having a slightly higher rate of metalwork failure.

Abstract
Abstract
Aim
The COVID-19 pandemic has resulted in significant pressures on the NHS. Healthcare workers (HCWs) are at increased risk of infection. Personal protective equipment (PPE) lowers the risk of infection transmission. However, during the early phases of the pandemic, the information available regarding COVD-19 and the use of PPE has been unclear, with constantly changing guidelines. The aim of this study was to determine the knowledge and confidence about PPE usage among HCWs, in addition to measuring their anxiety levels during the COVID pandemic.
Method
A validated questionnaire was distributed among HCWs in as many UK hospitals as possible, during April 2020. The questionnaire consisted of 13 questions regarding demographics, knowledge on PPE guidance, HCW training and confidence levels in PPE usage and finally anxiety levels measured using the GAD-7 psychometric tool.
Results
1055 responses were received. Nurses (49%), Healthcare Assistants (HCA - 20%), Doctors (17%), Physios (8%) and other (6%). 99% of respondents indicated they were familiar with PPE guidance, but only 1.6% answered all 3 questions on PPE guidance accurately. 86.4% of respondents received mask-fitting checks. 79.7% received donning-doffing training. Despite this, only 46.8% were confident on their familiarity with PPE. 32.5% felt that their hospital communication regarding PPE policy during COVID-19 pandemic was poor or very poor. 30% HCWs experienced severe anxiety.
Conclusions
National guidance and local training on PPE usage during the COVID-19 pandemic has been unsatisfactory, leading to higher anxiety among HCWs. Improved information delivery and training are essential in preparation for the second wave and future pandemics.

Abstract
Polyethylene glycol diacrylate (PEGDA) is an important class of photosensitive polymer with many tissue engineering applications. This study compared PEGDA and polycaprolactone (PCL) nanofiber matrix (NFM) coated PEGDA, referred to as PCL-PEGDA, scaffolds for their application in multiple tissue repair such as articular cartilage, nucleus pulposus of the intervertebral disc (IVD). We examined each scaffold morphology, porosity, swelling ratio, degradation, mechanical strength, andin vitrocytocompatibility properties. A defect was created in Sprague Dawley rat tail IVD by scraping native cartilage tissue and disc space, then implanting the scaffolds in the disc space for 4 weeks to evaluatein vivoefficacy of multi-tissue repair. Maintenance of disc height and creation of a new cell matrix was assessed to evaluate each scaffold's ability to repair the tissue defect. Although both PEGDA and PCL-PEGDA scaffolds showed similar porosity ∼73%, we observed distinct topographical characteristics and a higher effect of degradation on the water-absorbing capacity for PEGDA compared to PCL-PEGDA. Mechanical tests showed higher compressive strength and modulus of PCL-PEGDA compared to PEGDA.In vitrocell studies show that the PCL NFM layer covering PEGDA improved osteoblast cell adhesion, proliferation, and migration into the PEGDA layer.In vivostudies concluded that the PEGDA scaffold alone was not ideal for implantation in rat caudal disc space without PCL nanofiber coating due to low compressive strength and modulus.In vivoresults confirm that the PCL-PEGDA scaffold-maintained disc space and created a proteoglycan and collagen-rich new tissue matrix in the defect site after 4 weeks of scaffold implantation. We concluded that our developed PCL-PEGDA has the potential to be used in multi-tissue defect site repair.

Abstract
Outcomes have not improved for metastatic osteosarcoma for several decades. In part, this failure to develop better therapies stems from a lack of understanding of osteosarcoma biology, given the rarity of the disease and the high genetic heterogeneity at the time of diagnosis. We report here the successful establishment of a new human osteosarcoma cell line, COS-33, from a patient-derived xenograft and demonstrate retention of the biological features of the original tumor. We found high mTOR signaling activity in the cultured cells, which were sensitive to a small molecule inhibitor, rapamycin, a suppressor of the mTOR pathway. Suppressed mTOR signaling after treatment with rapamycin was confirmed by decreased phosphorylation of the S6 ribosomal protein. Increasing concentrations of rapamycin progressively inhibited cell proliferation in vitro. We observed significant inhibitory effects of the drug on cell migration, invasion, and colony formation in the cultured cells. Furthermore, we found that only a strong osteogenic inducer, bone morphogenetic protein-2, promoted the cells to differentiate into mature mineralizing osteoblasts, indicating that the COS-33 cell line may have impaired osteoblast differentiation. Grafted COS-33 cells exhibited features typical of osteosarcoma, such as production of osteoid and tumorigenicity in vivo. In addition, we revealed that the COS-33 cell line retained a complex karyotype, a homozygous deletion of the TP53 gene, and typical histological features from its original tumor. Our novel cellular model may provide a valuable platform for studying the etiology and molecular pathogenesis of osteosarcoma as well as for testing novel drugs for future genome-informed targeted therapy.

Abstract
BACKGROUND Major liver resection is associated with blood loss and transfusion. Observational data suggest that hypovolaemic phlebotomy can reduce these risks. This feasibility RCT compared hypovolaemic phlebotomy with the standard of care, to inform a future multicentre trial. METHODS Patients undergoing major liver resections were enrolled between June 2016 and January 2018. Randomization was done during surgery and the surgeons were blinded to the group allocation. For hypovolaemic phlebotomy, 7-10 ml per kg whole blood was removed, without intravenous fluid replacement. Co-primary outcomes were feasibility and estimated blood loss (EBL). RESULTS A total of 62 patients were randomized to hypovolaemic phlebotomy (31) or standard care (31), at a rate of 3·1 patients per month, thus meeting the co-primary feasibility endpoint. The median EBL difference was -111 ml (P = 0·456). Among patients at high risk of transfusion, the median EBL difference was -448 ml (P = 0·069). Secondary feasibility endpoints were met: enrolment, blinding and target phlebotomy (mean(s.d.) 7·6(1·9) ml per kg). Blinded surgeons perceived that parenchymal resection was easier with hypovolaemic phlebotomy than standard care (16 of 31 versus 10 of 31 respectively), and guessed that hypovolaemic phlebotomy was being used with an accuracy of 65 per cent (20 of 31). There was no significant difference in overall complications (10 of 31 versus 15 of 31 patients), major complications or transfusion. Among those at high risk, transfusion was required in two of 15 versus three of nine patients (P = 0·326). CONCLUSION Endpoints were met successfully, but no difference in EBL was found in this feasibility study. A multicentre trial (PRICE-2) powered to identify a difference in perioperative blood transfusion is justified. Registration number: NCT02548910 ( http://www.clinicaltrials.gov).

Abstract
Abstract
Introduction
Optogenetics is a low-invasive, flexible and highly selective intervention that enables electrical excitation with light on myocardium overexpressing light-sensitive proteins. Optical illumination can control the simultaneous exciting of the whole myocardium under the spot, which is more conducive to recovery from electrical disturbance to sinus rhythm.
Purpose
We explored optogenetic defibrillation for different illumination parameters how to affect defibrillation rates and the possible mechanism of continuous illumination defibrillation.
Methods
Systemic delivery via right jugular vein injection of (AAV9-CAG-hChR2(H134R)-mCherry) were performed in juvenile SD rats to achieve the light sensitive protein Channelrhodopsin-2 (ChR2) transfer throughout the whole heart. We intubated and ventilated rats, opened chest and recorded the ECG. After ligation of the left anterior descending coronary artery, ventricular arrhythmia was induced by electrical burst stimulation (10v, 50Hz, 2s). Cardiac epicardium illumination with 470nm blue laser was performed to investigate the effects of optogenetic defibrillation and its underlying mechanism. Every heart accepted 30 pulses of 20ms duration on 8Hz to test the light intensity threshold for 1:1 capture. Different illumination modes of multiple light intensity (2,4,8,10,20 times threshold intensity), pulse duration (20, 50, 200, 500 and 1000ms) and illumination position (RV apex, RV, RVOT, septum, LV) were applied in each attempt for 4 repetitions with 1 s interval.
Results
We demonstrated that ventricular arrhythmias could be terminated by illumination of the right ventricle at 20 times threshold intensity in 1s (figure A) with the successful defibrillation rate of 95±2.673% (mean ±SEM; N=7). Herein, the successful optogenetic defibrillation rate was strongly depending on light intensity (N=5, n=50 episodes, p=0.0118) and duration of illumination (N=5, n=50 episodes, p<0.0001) (figure B.C). Notably when there were higher intensity and longer pulse duration, the higher defibrillation rate appeared. There was no significant difference in the defibrillation rate among different illumination positions (N=5, n=25episodes per position, p=0.1177) (figure D). To explore the underlying mechanism of optogenetic defibrillation, we performed the same illumination mode during sinus rhythm in 2 rats (figure E. F. G). We observed that higher light intensity and longer pulse duration were more conducive to induce an episode of higher frequency focal excitement.
Views of optogenetic defibrillation
Conclusions
We demonstrated that optogenetic defibrillation is a highly effective intervention and the possible mechanism is partly attributed to overdrive suppression. We believe that optogenetic approach is potentially to be translated into more efficient and pain-free clinical termination of ventricular arrhythmia.

Abstract
Abstract
Background
The optogenetics manipulation of the heart based on the visible light is limited in the therapeutic potential because of the low tissue penetration. Near-infrared (NIR) light has deeper tissue penetration capabilities but radiates at unsuitable wavelengths, while upconversion nanoparticles (UCNPs) absorb NIR light to convert visible light.
Purpose
We aimed to investigate the efficient NIR control of the rat heart in vivo via UCNPs mediated cardiac optogenetics.
Methods
Systemic delivery via jugular vein injection of (AAV9-CAG-hChR2 (H134R)-mCherry) were performed in SD rats to achieve sufficient Channelrhodopsin-2 (ChR2) transfer throughout the whole heart. UCNPs of NaYF4:Yb/Tm with optimal excitation wavelength at 975nm were chosen to emit upconverted blue light. Different concentrations of UCNPs cyclohexane solution were embed in composite polydimethylsiloxane films to make flexible substrates for cardiac optogenetics study in open-chest rats (n=3). The UCNPs film was attached to the right ventricle and the 980nm NIR illumination was applied.
Results
The upconversion luminescence spectra of four concentrations (2.5, 5, 10 and 20mg/ml) of NaYF4:Yb/Tm scanned under 980nm excitation at 0.5w showed similar peaks around 475, 645 and 695nm. Emission intensity increased with the UCNPs concentration (Figure 1). The NIR-upconverted blue light from the freestanding films embedded with 2.5 and 5mg/ml UCNPs failed to capture the heart till the peak output power of the NIR laser, and the hearts were successfully captured and paced by the upconverted blue light from 10 and 20mg/mL UCNPs films (20 pulses in 8Hz with 20ms duration were repeated 3 times with the interval of 1s). However the NIR power was lower on 10mg/mL UCNPs film than the 20mg/mL one (0.93±0.11w vs 1.71±0.75w). Therefore, UCNPs film with concentration of 10mg/mL NaYF4:Yb/Tm were used for efficient cardiac optogenetic pacing by NIR light from a 400um optical fiber. Optogenetics capture of the ventricle was achieved at different NIR power, pulse duration and flash frequency. The strength-duration curve summarized the minimal NIR irradiance power of 8Hz flash required for 100% capture at different pulse duration (2, 5, 10, 20 and 50ms). Notably the longer the pulse duration was, the lower the light intensity required. Furthermore, the increasing flash frequency (6, 7, 8 and 10Hz) of the NIR light setting at 1.66w (2-fold threshold power) and 20ms duration induced sufficient cardiac pacing (Figure 2).
The efficient NIR control of the heart
Conclusion
We demonstrated the successful NIR photo-activation of ChR2 expressed in the heart by the upconverted blue light via UCNPs, which resulted in a flexible UCNPs-assisted cardiac optogenetic approach for optical control of heart activity. We believe that these advances in cardiac optogenetic toolbox not only represent a novel practical application of UCNPs, but also open up new possibilities for remote or tissue penetrating heart control.

Abstract
Juvenile myelomonocytic leukemia (JMML) has a poor prognosis in general, with hematopoietic stem cell transplant (HSCT) remaining the standard of care for cure. The hypomethylating agent, azacitidine, has been used as a bridging therapy to transplant. However, no patients have been treated with azacitidine without an HSCT post azacitidine. We report on an infant with JMML with somatic KRAS G12A mutation and monosomy 7 who achieved sustained remission following azacitidine monotherapy. He also developed an aberrant B-lymphoblast population which declined with similar kinetics as his JMML-associated abnormalities, suggesting that a B-lymphoblast population in JMML does not always progress to acute leukemia.

Abstract
OBJECTIVE The role of serotonin (5-HT) in human aggression has been the subject of a large number of studies, mostly with adults. Meta-analyses indicate a small but significant inverse relationship between central nervous 5-HT availability and aggression, but genetically informed studies suggest two pathways: one to reactive aggression and the other to proactive aggression. METHOD We conducted a systemic review on central nervous 5-HT function in children and adolescents, with attention to the function of aggression. RESULTS In total, 675 articles were screened for relevance, with 45 reviewed. These included blood assays (e.g. plasma, 5-HIAA; platelet 5-HTR2A ), epigenetic studies, retrospective PET studies and 5-HT challenge paradigms (e.g. tryptophan depletion). Overall, findings were mixed, with support both for negative and for positive associations of central nervous 5-HT function with aggression in children and adolescents. CONCLUSION We propose factors that may be blurring the picture, including problems in the conceptualization and measurement of aggression in young people, the lack of prospective designs and the bias towards clinical samples of boys. Research needs to account for variance in the both motivation for and implementation of aggression, and look to the behavioural economics literature to consider the roles of reward, vengeance and self-control more clearly.

Abstract
We report on quantum capacitance measurements of high quality, graphite and hexagonal boron nitride encapsulated Bernal stacked trilayer graphene devices. At zero applied magnetic field, we observe a number of electron density- and electrical displacement-tuned features in the electronic compressibility associated with changes in Fermi surface topology. At a high displacement field and low density, strong trigonal warping gives rise to three new emergent Dirac cones in each valley, which we term "gullies." The gullies are centered around the corners of a hexagonal Brillouin zone and related by threefold rotation symmetry. At low magnetic fields of B=1.25 T, the gullies manifest as a change in the degeneracy of the Landau levels from two to three. Weak incompressible states are also observed at integer filling within these triplet Landau levels, which a Hartree-Fock analysis indicates are associated with Coulomb-driven nematic phases that spontaneously break rotation symmetry.

Abstract
Lymphangioma of the pancreas is rare and presents as a large cystic mass in the retroperitoneum. The pancreatic origin can be confirmed by careful evaluation of cross sectional imaging. Preoperative differentiation from other pancreatic cystic neoplasms is difficult but possible. Large symptomatic lesions warrant surgery. The diagnosis is confirmed by typical features on histopathology and immunohistochemistry. Presented here is a case report of a pancreatic lymphangioma, discussed in the context of available literature.

Abstract
INTRODUCTION Recurrent miscarriage (RM) defined as 2 or more spontaneous miscarriage before 20 weeks of gestation, affects at least 1 % of couples trying to conceive. In over 50 % of cases, the cause of the loss of pregnancy remains unexplained. Reduced expression of Angiogenic factors such as: vascular endothelial growth factor (VEGF-A) and VEGF-C has been linked with spontaneous miscarriage, likely due to defective foetal and placental angiogenesis. AIMS AND OBJECTIVES To investigate the relationships between serum level of VEGF-A and VEGF-C with clinical characteristic in women with URM and compare to pregnant and healthy women. MATERIALS AND METHODS A case-control study, which was conducted between 90 non-pregnant women with history of RM, age-matched with 70 non-pregnant women without history of recurrent abortion with at least one child (controls) and 70 pregnant women without history of recurrent abortion with at least one child (controls). Those with unexplained RM were eligible. Demographic and Anthropometric data were retrieved by pre-test questionnaire and serum level of VEGF-A and VEGF-C measured by ELISA kit. RESULTS This study showeds that maternal levels of VEGF-A and VEGF-C were distinctly lower in RSA (189.87±88.1 vs 238.8±99.6) compared to healthy (239.1±99.7 vs 275.5±133.08) and pregnant (301.5±76.4 vs 402.5±128.6) women as control groups. Univariate analysis demonstrated that clinical characteristic factors were significantly associated with concentration of VEGF-A and VEGF-C in cases and controls. CONCLUSIONS Our findings suggest that these molecules could be used as potential predictive markers of miscarriage in these women presenting with URM (Tab. 4, Fig. 5, Ref. 40).

Abstract
Osteosarcoma is the most common primary malignant bone tumor in children and young adults. Although histologically defined by the presence of malignant osteoid, the tumor possesses lineage multipotency suggesting it could be derived from a cell anywhere on the differentiation pathway between a mesenchymal stem cell (MSC) and a mature osteoblast. To determine if preosteoblasts (pOB) could be the cell of origin differentiated MSCs were transformed with defined genetic elements. MSCs and pOB differentiated from the same MSCs were serially transformed with the oncogenes hTERT, SV40 large T antigen and H-Ras. Assays were performed to determine their tumorigenic properties, differentiation capacity and histologic appearance. When subcutaneously implanted in immunocompromised mice, cell lines derived from transformed MSC and pOB formed tumors in 4 weeks. In contrast to the transformed MSC, the pOB tumors demonstrated a histological appearance characteristic of osteosarcoma. The cell lines derived from the transformed pOB only had osteogenic and chondrogenic differentiation potential, but not adipogenic ones. However, the transformed MSC cells and standard osteosarcoma cell lines maintained their tri-lineage differentiation capacity. The inability of the transformed pOB cell line to undergo adipogenic differentiation, may suggest that osteosarcoma is derived from a cell intermediate in differentiation between an MSC and a pOB, with partial commitment to the osteoblastic lineage.

Abstract
A 38-year-old female on Vitamin D therapy presented with hypercalcemia induced acute kidney injury. Evaluation revealed primary hyperparathyroidism (PHPT) and iatrogenic hypervitaminosis D. After medical stabilization, she underwent surgical removal of the parathyroid adenoma, and made a full recovery. This case highlights unmasking of subclinical hyperparathyroidism by vitamin D therapy leading to severe hypercalcemia.

Abstract
OBJECTIVE To evaluate the diagnostic accuracy and safety of magnetic resonance imaging (MRI)-guided percutaneous biopsy of mediastinal masses performed using a wide-bore high-field scanner. MATERIALS AND METHODS This is a retrospective study of 16 consecutive patients (8 male, 8 female; mean age 74 years) who underwent MRI-guided core needle biopsy of a mediastinal mass between February 2010 and January 2014. Size and location of lesion, approach taken, time for needle placement, overall duration of procedure, and post-procedural complications were evaluated. Technical success rates and correlation with surgical pathology (where available) were assessed. RESULTS Target lesions were located in the anterior (n = 13), middle (n = 2), and posterior mediastinum (n = 1), respectively. Mean size was 7.2 cm (range 3.6-11 cm). Average time for needle placement was 9.4 min (range 3-18 min); average duration of entire procedure was 42 min (range 27-62 min). 2-5 core samples were obtained from each lesion (mean 2.6). Technical success rate was 100%, with specimens successfully obtained in all 16 patients. There were no immediate complications. Histopathology revealed malignancy in 12 cases (4 of which were surgically confirmed), benign lesions in 3 cases (1 of which was false negative following surgical resection), and one inconclusive specimen (treated as inaccurate since repeat CT-guided biopsy demonstrated thymic hyperplasia). Sensitivity, specificity, positive predictive value, negative predictive value, and accuracy in our study were 92.3, 100, 100, 66.7, and 87.5%, respectively. CONCLUSION MRI-guided mediastinal biopsy is a safe procedure with high diagnostic accuracy, which may offer a non-ionizing alternative to CT guidance.

Abstract
BACKGROUND Hepatitis A virus (HAV) and Hepatitis E virus (HEV) are both enterically transmitted, resulting in acute viral hepatitis (AVH) in developing countries. They pose major health problems in our country. This study was done to determine prevalence of HAV and HEV in patients presenting with AVH and the co-infection of HAV and HEV in these patients. MATERIALS AND METHODS A cross-sectional study of 2-years duration was conducted in the Department of Microbiology, KMC, Mangalore. A non-random sampling of 958 patients presenting with AVH was considered in the study. On the basis of history, serum samples were analysed for IgM anti-HAV and IgM anti-HEV for the detection of HAV and HEV, respectively using commercially available ELISA kits. Data collected was analysed by using Statistical Package for the Social Sciences (SPSS) version 11.5. RESULTS The seroprevalence of HAV- and HEV-positive patients were 19.31% and 10.54%, respectively. The seroprevalence of both HAV and HEV in patients with acute viral hepatitis was 11.5%. The prevalence of HAV and HEV among males (68% and 31%) was higher than in females (31% and 20%) and was predominantly seen among young adults. These infections were predominantly seen during end of monsoons and beginning of winter. CONCLUSION Though the prevalence of HAV is much higher than that of HEV, co-infection rate of 11.5% mandates the screening for HEV which will be of immense importance in pregnant women and improving levels of personal hygiene among higher socio-economic population. These data will be essential for planning of future vaccination strategies and for better sanitation programme in this part of the country.

Abstract
Cardiac progenitor/stem cells in adult hearts represent an attractive therapeutic target for heart regeneration, though (inter)-relationships among reported cells remain obscure. Using single-cell qRT-PCR and clonal analyses, here we define four subpopulations of cardiac progenitor/stem cells in adult mouse myocardium all sharing stem cell antigen-1 (Sca1), based on side population (SP) phenotype, PECAM-1 (CD31) and platelet-derived growth factor receptor-α (PDGFRα) expression. SP status predicts clonogenicity and cardiogenic gene expression (Gata4/6, Hand2 and Tbx5/20), properties segregating more specifically to PDGFRα(+) cells. Clonal progeny of single Sca1(+) SP cells show cardiomyocyte, endothelial and smooth muscle lineage potential after cardiac grafting, augmenting cardiac function although durable engraftment is rare. PDGFRα(-) cells are characterized by Kdr/Flk1, Cdh5, CD31 and lack of clonogenicity. PDGFRα(+)/CD31(-) cells derive from cells formerly expressing Mesp1, Nkx2-5, Isl1, Gata5 and Wt1, distinct from PDGFRα(-)/CD31(+) cells (Gata5 low; Flk1 and Tie2 high). Thus, PDGFRα demarcates the clonogenic cardiogenic Sca1(+) stem/progenitor cell.

Abstract
Fungal infections of the urinary tract are usually encountered following prolonged antibiotic use, instrumentation and indwelling urinary catheters. These type of infections are mostly seen in immuno-compromised patients. Candida is the most common among the fungal infections of urinary tract followed by Aspergillus infection. Here is a case report of a 26 year old diabetic female who presented with abdominal pain, fever, nausea and vomiting. She had undergone double-J stenting 15-20 days back. The cause of the symptoms was not detected till the patient underwent C.T Scan-KUB with excretory urography which showed the displaced D-J stent. Then on performing replacement of D-J stent, cystoscopy was done and the tissue sample was sent for microbiological and histopathological examination. On Microbiological examination, Aspergillus flavus was isolated from the tissue, which was culprit behind the disease. Patient was then treated with anti-fungal drugs, following which she gradually improved.

Abstract
The shortage of donors in cardiac transplantation may be alleviated by the use of allografts from donation after circulatory death (DCD) donors. We have previously shown that hearts exposed to 30 min warm ischemic time and then flushed with Celsior supplemented with agents that activate ischemic postconditioning pathways, show complete recovery on a blood-perfused ex vivo working heart apparatus. In this study, these findings were assessed in a porcine orthotopic heart transplant model. DCD hearts were preserved with either normothermic ex vivo perfusion (NEVP) using a clinically approved device, or with standard cold storage (CS) for 4 h. Orthotopic transplantation into recipient animals was subsequently undertaken. Five of six hearts preserved with NEVP demonstrated favorable lactate profiles during NEVP and all five could be weaned off cardiopulmonary bypass posttransplant, compared with 0 of 3 hearts preserved with CS (p < 0.05, Fisher's exact test). In conclusion, DCD hearts flushed with supplemented Celsior solution and preserved with NEVP display viability before and after transplantation. Viability studies of human DCD hearts using NEVP are warranted.

Abstract
BACKGROUND New therapeutic targets are needed to eliminate cancer stem cells (CSCs). We hypothesize that direct comparison of paired CSCs and nonstem tumor cells (NSTCs) will facilitate identification of primary "driver" chromosomal aberrations that can serve as diagnostic markers and/or therapeutic targets. METHODS We applied spectral karyotyping and G-banding to matched pairs of neurospheres (CSC-enriched cultures) and fetal bovine serum-based monolayer cultures (enriched with NSTCs) from 16 patient-derived orthotopic xenograft mouse models, including 9 medulloblastomas (MBs) and 7 high-grade gliomas (HGGs), followed by direct comparison of their numerical and structural abnormalities. RESULTS Chromosomal aberrations were detected in neurospheres of all 16 models, and 82.0% numerical and 82.4% structural abnormalities were maintained in their matching monolayer cultures. Among the shared abnormalities, recurrent clonal changes were identified including gain of chromosomes 18 and 7 and loss of chromosome 10/10q (5/16 models), isochromosome 17q in 2 MBs, and a new breakpoint of 13q14 in 3 HGGs. Chromothripsis-like evidence was also observed in 3 HGG pairs. Additionally, we noted 20 numerical and 15 structural aberrations that were lost from the neurospheres and found 26 numerical and 23 structural aberrations that were only present in the NSTCs. Compared with MBs, the neurosphere karyotypes of HGG were more complex, with fewer chromosomal aberrations preserved in their matching NSTCs. CONCLUSION Self-renewing CSCs in MBs and pediatric HGGs harbor recurrent numerical and structural aberrations that were maintained in the matching monolayer cultures. These primary chromosomal changes may represent new markers for anti-CSC therapies.
