Research Note: Effect of dietary xylo-oligosaccharide on growth performance, intestinal histomorphology, and specific cecal bacteria in broiler chickens.

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

Daily waiting time management for modern radiation oncology department in Indian perspective.

Introduction: Radiation therapy is one of the most technically sophisticated branch of medical sciences which caters to very ill patients, some of whom may be terminally ill. Since patients are treated on an outpatient basis which requires daily visit to hospital for a number of days, it can make them sensitive toward any increase in waiting time for their radiation treatment. This could be a source of stress for them. However, given the technical sophistication involved and varied clinical profile of patients, some amount of delay is inevitable. Aim & Objective: To compile and suggest strategies to manage patient waiting time in Radiation oncology department to achieve optimum patient' satisfaction. Method: The radiation oncologists in different institutes of the country were interviewed telephonically and were asked about the practices followed in their institutes/ departments in managing the patient waiting time during radiation treatment. The best practices being followed and the suggestions were compiled. Conclusion: Now it is being recognized that meticulous management of waiting time could go a long way in driving patient's satisfaction. Twoway communications are the best strategy. Apart from this many provisions could be made in waiting area as per institutional preferences and protocol to engage patient in waiting area of radiation treatment facility.

Antibodies against phosphorylcholine in hospitalized versus non-hospitalized obese subjects.

Obesity associates with reduced life expectancy, type 2 diabetes, hypertension and cardiovascular disease, and is characterized by chronic inflammation. Phosphorylcholine (PC) is an epitope on oxidized low-density lipoprotein, dead cells and some microorganisms. Antibodies against PC (anti-PC) have anti-inflammatory properties. Here, we explored the role of anti-PC in hospitalized versus non-hospitalized obese. One-hundred-and-twenty-eight obese (BMI ≥ 30 kg/m2) individuals (59.8 (± 5.5) years, 53.9% women) from the Malmö Diet and Cancer Cardiovascular Cohort were examined and IgM, IgG1 and IgG2 anti-PC were analyzed by ELISA. Individuals with at least one recorded history of hospitalization prior to study baseline were considered hospitalized obese (HO). Associations between IgM, IgG1 and IgG2 anti-PC and HO (n = 32)/non-hospitalized obese (NHO) (n = 96), but also with metabolic syndrome and diabetes were analysed using logistic regressions. Both IgM and IgG1 anti-PC were inversely associated with HO, also after controlling for age and sex. When further adjusted for waist circumference, systolic blood pressure, glucose levels and smoking status, only IgG1 anti-PC remained significantly associated with HO. In multivariate models, each 1 standard deviation of increment in anti-PC IgG1 levels was inversely associated with prevalence of HO (odds ratio 0.57; CI 95% 0.33-0.98; p = 0.044). IgG2 anti-PC did not show any associations with HO. Low levels of IgM and IgG1 anti-PC are associated with higher risk of being a HO individual independent of sex and age, IgG1 anti-PC also independently of diabetes and metabolic syndrome. The anti-inflammatory properties of these antibodies may be related to inflammation in obesity and its complications.

Delivering computationally-intensive digital patient applications to the clinic: An exemplar solution to predict femoral bone strength from CT data.

BACKGROUND AND OBJECTIVE: Whilst fragility hip fractures commonly affect elderly people, often causing permanent disability or death, they are rarely addressed in advance through preventive techniques. Quantification of bone strength can help to identify subjects at risk, thus reducing the incidence of fractures in the population. In recent years, researchers have shown that finite element models (FEMs) of the hip joint, derived from computed tomography (CT) images, can predict bone strength more accurately than other techniques currently used in the clinic. The specialised hardware and trained personnel required to perform such analyses, however, limits the widespread adoption of FEMs in clinical contexts. In this manuscript we present CT2S (Computed Tomography To Strength), a system developed in collaboration between The University of Sheffield and Sheffield Teaching Hospitals, designed to streamline access to this complex workflow for clinical end-users. METHODS: The system relies on XNAT and makes use of custom apps based on open source software. Available through a website, it allows doctors in the healthcare environment to benefit from FE based bone strength estimation without being exposed to the technical aspects, which are concealed behind a user-friendly interface. Clinicians request the analysis of CT scans of a patient through the website. Using XNAT functionality, the anonymised images are automatically transferred to the University research facility, where an operator processes them and estimates the bone strength through FEM using a combination of open source and commercial software. Following the analysis, the doctor is provided with the results in a structured report. RESULTS: The platform, currently available for research purposes, has been deployed and fully tested in Sheffield, UK. The entire analysis requires processing times ranging from 3.5 to 8 h, depending on the available computational power. CONCLUSIONS: The short processing time makes the system compatible with current clinical workflows. The use of open source software and the accurate description of the workflow given here facilitates the deployment in other centres.

Haemorrhagic shock from solid tumours of the adrenal gland: a case of bleeding primary adrenal lymphoma.

Suprarenal or adrenal gland haemorrhage is an uncommon but potentially lethal condition if unrecognised. Adrenal masses rarely present with haemorrhage, but they remain an important differential aetiology for adrenal bleeding. We present a novel case of primary adrenal lymphoma with adrenal haemorrhage in a middle-aged woman who presented with right-sided abdominal pain and class 1 haemorrhagic shock. She was found to have spontaneous unilateral adrenal gland haemorrhage in the absence of any underlying previous pathology. Presenting features, diagnosis and subsequent oncological management are reported.

COPD exacerbation rates are higher in non-smoker patients in India.

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is common among non-smokers exposed to solid fuel combustion at home. Different clinical characteristics in these patients may have significant therapeutic and prognostic implications.METHODS: We used medical record review and a questionnaire among COPD patients at 15 centres across India to capture data on demographic details, different types of exposures and clinical characteristics. Chest radiography and pulmonary function testing were performed in all 1984 cases; C-reactive protein and exhaled breath nitric oxide were measured wherever available.RESULTS: There were 1388 current or ex-smokers and 596 (30.0%) non-smokers who included 259 (43.5%) male and 337 (56.5%) female patients. Sputum production was significantly more common in smokers with COPD (P < 0.05). The frequency of acute symptomatic worsening, emergency visits and hospitalisation were significantly higher (P < 0.05) in non-smokers with COPD; however, intensive care unit admissions were similar in the two groups. There was no significant difference with respect to the use of bronchodilators, inhalational steroids or home nebulisation among smoker and non-smoker patients. The mean predicted forced expiratory volume in 1 sec in smokers (43.1%) was significantly lower than in non-smokers (46.5%).CONCLUSION: Non-smoker COPD, more commonly observed in women exposed to biomass fuels, was characterised by higher rate of exacerbations and higher healthcare resource utilisation.

Anastomotic dehiscence following retroflexion in surveillance colonoscopy: a case report.

Anastomotic dehiscence following colonoscopy for routine surveillance after anterior resection for colorectal cancer is unreported in the English literature. It is a potentially fatal complication requiring awareness, quick recognition and management. We present the case of a 45-year-old woman who presented 12 hours after a routine follow-up colonoscopy with peritonitis due to anastomotic rupture diagnosed on computed tomography. The patient was taken to theatre for emergency laparotomy and formation of an end colostomy. Her postoperative recovery and follow-up were optimal.

A novel digital method to assess air space loss associated with acute lung injury in experimental acute pancreatitis.

BACKGROUND/OBJECTIVES: Respiratory dysfunction and/or failure from acute lung injury (ALI) are common in acute pancreatitis (AP), but assessment of ALI in experimental AP has lacked standardisation. METHODS: A range of experimental AP models induced in C57BL/6 mice with corresponding controls (n = 6/group). Full double lung or right lung specimens were taken for histopathological assessment and slides analysed by a pre-set pipeline using Aperio Scanner (Leica), ImageJ software and CellProfiler software. Findings were compared to other routinely assessed parameters. RESULTS: Overall histopathological changes were similar between both lungs. Mean lung field occupancy was significantly different between moderate and severe CER-AP (21.9% v 27.5%, p < 0.05) and corresponded with lung MPO and local injury severity parameters and was mirrored for all models tested. CONCLUSION: We have developed a novel, simple method for assessment of ALI to improve measurement of systemic organ injury in experimental AP and contribute to preclinical drug development.

Improved UV Photodetection by Indium Doped TiO2 Thin Film Based Photodetector.

Indium (In) was doped into TiO2 thin film (TF) using the electron beam evaporation technique followed by an annealing process. The high resolution X-ray diffraction (HRXRD) analysis revealed lower angle diffraction peak (2) shifting of Rutile (002) phases of TiO2 from 61.9 to 61.56 for an increased In doped samples. Calculated average grain size from FESEM (field emission scanning electron microscope) gradually decreased from 21.12 nm to 17.03 mm with an increase in In content ranging from 1.45~17.30 at%. HRXRD data revealed that crystallite sizes also reduced from 21.79 nm to 16.93 nm with an increased In doping concentration. Doping of In leads to the formation of inhomogeneous InxTiy O2 alloy that enhances the transition between 3.3-3.42 eV energy levels with variation in doping concentration. The photo-efficiencies for increased doping concentration of In with 3.47 at% and 17.30 at% were enhanced by 2.56 and 2.76 times, respectively, compared to the undoped TiO2 TF detector and both were larger than low doped In with 1.45 at% sample. The ratio of main band detection intensity to oxygen defect level was also increased from 0.22 to 2.22 with the gradual increase in In content.

Spectrum of Glomerular Diseases in Adults: A Study from North Eastern India.

AIMS AND OBJECTIVES: To study the clinical profile of patients with glomerular diseases and to study pattern of glomerular diseases in adults. METHODOLOGY: A hospital based retrospective observational study from North Eastern India that includes biopsy proven glomerular disease (GD) in adults. Patients with inadequate biopsy sampling; incomplete medical data and biopsy of transplanted kidney were excluded. RESULTS AND OBSERVATIONS: A total of 102 patients were included of which 25 (24.5%) were male and 77(75.5%) were female with M: F ratio of 0.32:1. The mean age of presentation was 30.6 years. Nephrotic syndrome (57.8%) was the commonest clinical diagnosis followed by acute nephritic syndrome (31.4%), unexplained AKI (5.9%), unexplained CKD with normal kidney size (2.9%) and asymptomatic urine abnormality (1.9%). On histo-pathological analysis primary GD and secondary GD was diagnosed in 46(45.1%) and 53(52.0%) respectively. Overall Lupus nephritis (LN) was found to be the commonest (41.2%) GD. Among the primary GD, MCD (11.8%) was the most frequent followed by MPGN (10.8%), Membranous Nephropathy, (5.8%), IgA nephropathy (5.8%) and Focal segmental glomerulosclerosis (5.8%). Three (2.9%) patients did not have any specific diagnosis and were labelled as chronic glomerulo- nephritis.. CONCLUSIONS: As the pattern of glomerular disease varies from one region to another, the pattern of glomerular disease in the north eastern India also varies from the other regions of India. Nephrotic syndrome remains the most common indication of renal biopsy in this region similar to the other parts of India. Unlike other studies from outside North Eastern India, this study show that females are more commonly involved with majority of them having secondary GD and this is due to LN which was diagnosed as the most common GD in the present study.

Sustained intra-cartilage delivery of low dose dexamethasone using a cationic carrier for treatment of post traumatic osteoarthritis.

Disease-modifying osteoarthritis drugs (DMOADs) should reach their intra-tissue target sites at optimal doses for clinical efficacy. The dense, negatively charged matrix of cartilage poses a major hindrance to the transport of potential therapeutics. In this work, electrostatic interactions were utilised to overcome this challenge and enable higher uptake, full-thickness penetration and enhanced retention of dexamethasone (Dex) inside rabbit cartilage. This was accomplished by using the positively charged glycoprotein avidin as nanocarrier, conjugated to Dex by releasable linkers. Therapeutic effects of a single intra-articular injection of low dose avidin-Dex (0.5 mg Dex) were evaluated in rabbits 3 weeks after anterior cruciate ligament transection (ACLT). Immunostaining confirmed that avidin penetrated the full cartilage thickness and was retained for at least 3 weeks. Avidin-Dex suppressed injury-induced joint swelling and catabolic gene expression to a greater extent than free Dex. It also significantly improved the histological score of cell infiltration and morphogenesis within the periarticular synovium. Micro-computed tomography confirmed the reduced incidence and volume of osteophytes following avidin-Dex treatment. However, neither treatment restored the loss of cartilage stiffness following ACLT, suggesting the need for a combinational therapy with a pro-anabolic factor for enhancing matrix biosynthesis. The avidin dose used caused significant glycosaminoglycan (GAG) loss, suggesting the use of higher Dex : avidin ratios in future formulations, such that the delivered avidin dose could be much less than that shown to affect GAGs. This charge-based delivery system converted cartilage into a drug depot that could also be employed for delivery to nearby synovium, menisci and ligaments, enabling clinical translation of a variety of DMOADs.

Microsatellite Instability in Chronic Myeloid Leukemia using D17S261 and D3S643 markers: A Pilot Study in Gujarat Population.

CONTEXT: Tumor progresses through a series of genetic alterations that involve proto-oncogenes and tumor suppressor genes - the gatekeeper, caretakers, and landscaper genes. Microsatellites are short tandem repeat sequences, present over the span of human genome and are known to be variable at multiple loci due to errors in DNA Mismatch Repair machinery. AIM: The present study was aimed to evaluate the association between Microsatellite Instability (MSI) and evolution of Chronic Myeloid Leukemia (CML) - genetically a rare event but profound in this pilot study. SETTINGS AND DESIGNS: We explore the possibility of MSI in primary CML patients confirmed by t(9;22) using capillary electrophoresis. Fifteen CML patients and healthy individual samples, respectively, were used to study the markers D17S261 and D3S643. MATERIALS AND METHODS: The DNA was amplified using tagged and nontagged primers and further subjected to bioanalysis and fragment analysis. RESULTS: While the results from bioanalyzer fluctuated, fragment analysis indicated the presence of microsatellite variability in 80% of the patients' samples as compared to no MSI in normal individuals for both the markers. CONCLUSION: These findings suggest that MSI is a genetic event that may have a role in CML progression or evolution. Further studies are warranted to understand the plausible underlying causes.

Evaluation of 19,460 Wheat Accessions Conserved in the Indian National Genebank to Identify New Sources of Resistance to Rust and Spot Blotch Diseases.

A comprehensive germplasm evaluation study of wheat accessions conserved in the Indian National Genebank was conducted to identify sources of rust and spot blotch resistance. Genebank accessions comprising three species of wheat-Triticum aestivum, T. durum and T. dicoccum were screened sequentially at multiple disease hotspots, during the 2011-14 crop seasons, carrying only resistant accessions to the next step of evaluation. Wheat accessions which were found to be resistant in the field were then assayed for seedling resistance and profiled using molecular markers. In the primary evaluation, 19,460 accessions were screened at Wellington (Tamil Nadu), a hotspot for wheat rusts. We identified 4925 accessions to be resistant and these were further evaluated at Gurdaspur (Punjab), a hotspot for stripe rust and at Cooch Behar (West Bengal), a hotspot for spot blotch. The second round evaluation identified 498 accessions potentially resistant to multiple rusts and 868 accessions potentially resistant to spot blotch. Evaluation of rust resistant accessions for seedling resistance against seven virulent pathotypes of three rusts under artificial epiphytotic conditions identified 137 accessions potentially resistant to multiple rusts. Molecular analysis to identify different combinations of genetic loci imparting resistance to leaf rust, stem rust, stripe rust and spot blotch using linked molecular markers, identified 45 wheat accessions containing known resistance genes against all three rusts as well as a QTL for spot blotch resistance. The resistant germplasm accessions, particularly against stripe rust, identified in this study can be excellent potential candidates to be employed for breeding resistance into the background of high yielding wheat cultivars through conventional or molecular breeding approaches, and are expected to contribute toward food security at national and global levels.

Development of Cotton leaf curl virus resistant transgenic cotton using antisense ßC1 gene.

Cotton leaf curl virus (CLCuV) is a serious pathogen causing leaf curl disease and affecting the cotton production in major growing areas. The transgenic cotton (Gossypium hirsutum cv. Coker 310) plants were developed by using ßC1 gene in antisense orientation gene driven by Cauliflower mosaic virus-35S promoter and nos (nopaline synthase) terminator and mediated by Agrobacterium tumefaciens transformation and somatic embryogenesis system. Molecular confirmation of the transformants was carried out by polymerase chain reaction (PCR) and Southern blot hybridization. The developed transgenic and inoculated plants remained symptomless till their growth period. In conclusion, the plants were observed as resistant to CLCuV.

Oral Submucous Fibrosis Secondary to Iron Deficiency Anemia: A Case Report, Etiopathogenesis and Management.

Oral submucous fibrosis (OSMF) is a premalignant condition that has received considerable attention in the recent past because of its chronic debilitating and resistant nature. Over the past decades, dental researchers have reported overwhelming evidence about various etiological factors of OSMF. It has been the subject of controversy ever since Schwartz first described the condition in 1952. Areca nut is considered the primary etiology along with other local irritants like capsaicin, pungent and spicy food, nutritional deficiency, defective iron metabolism, collagen metabolic disorder and genetic predisposition. Association of iron deficiency anemia and OSMF is very sparse in literature. Here, we present a case report of a 58 year old male patient where the patient presented with OSMF where iron deficiency anemia was found to be the main etiological factor.

Development of interspecific Solanum lycopersicum and screening for Tospovirus resistance.

Tospovirus has emerged as a serious viral pathogen for several crops including tomato. The tomato production is being severely affected worldwide by Tospovirus. Some reports have been published about the association of plant virus and development of human disease either by direct or indirect consumption. Resistance to this virus has been identified as good source in wild tomato species (Lycopersicum peruvianum). But the introgression of resistance genes into cultivated tomato lines and the development of interspecific hybrid are hampered due to incompatibility, fertilization barriers and embryo abortion. But this barrier has been broken by applying the embryo rescue methods. This study describes the development of interspecific hybrid tomato plants by highly efficient embryo rescue method and screening for Tospovirus resistance. The interspecific hybrid tomato plants were developed by making a cross between wild tomato species (L. peruvianum) and cultivated tomato (Solanum lycopersicum). The immature embryos were cultured in standardized medium and interspecific hybrids were developed from embryogenic callus. The immature embryos excised from 7 to 35 days old fruits were used for embryo rescue and 31 days old embryos showed very good germination capabilities and produced the highest number of plants. Developed plants were hardened enough and shifted to green house. The hybrid nature of interspecific plants was further confirmed by comparing the morphological characters from their parents. The F1, F2 and F3 plants were found to have varying characters especially for leaf type, color of stem, fruits, size, shapes and they were further screened for virus resistance both in lab and open field followed by Enzyme linked Immunosorbant Assay confirmation. Finally, a total of 11 resistant plants were selected bearing red color fruits with desired shape and size.

Mechanical competence of ovariectomy-induced compromised bone after single or combined treatment with high-frequency loading and bisphosphonates.

Osteoporosis leads to increased bone fragility, thus effective approaches enhancing bone strength are needed. Hence, this study investigated the effect of single or combined application of high-frequency (HF) loading through whole body vibration (WBV) and alendronate (ALN) on the mechanical competence of ovariectomy-induced osteoporotic bone. Thirty-four female Wistar rats were ovariectomized (OVX) or sham-operated (shOVX) and divided into five groups: shOVX, OVX-shWBV, OVX-WBV, ALN-shWBV and ALN-WBV. (Sham)WBV loading was applied for 10 min/day (130 to 150 Hz at 0.3g) for 14 days and ALN at 2 mg/kg/dose was administered 3x/week. Finite element analysis based on micro-CT was employed to assess bone biomechanical properties, relative to bone micro-structural parameters. HF loading application to OVX resulted in an enlarged cortex, but it was not able to improve the biomechanical properties. ALN prevented trabecular bone deterioration and increased bone stiffness and bone strength of OVX bone. Finally, the combination of ALN with HF resulted in an increased cortical thickness in OVX rats when compared to single treatments. Compared to HF loading, ALN treatment is preferred for improving the compromised mechanical competence of OVX bone. In addition, the association of ALN with HF loading results in an additive effect on the cortical thickness.
