Abstract
OBJECTIVES Mucositis is a common morbidity in patients undergoing bone marrow transplant. Various agents have been used to prevent and treat it with variable success. Here, we assessed the efficacy of supersaturated calcium phosphate rinses in prevention and treatment of oral mucositis in patients undergoing hematopoietic stem cell transplant. MATERIALS AND METHODS In this retrospective study, we evaluated the records of 80 patients who underwent hematopoietic stem cell transplant and received supersaturated calcium phosphate rinses for preVention of mucositis from April 2012 to January 2016. The World Health Organization scale was used to grade mucositis. Various parameters assessed included grade of mucositis, duration of mucositis, peak mucositis day, duration of pain, peak pain day, duration of total parenteral nutrition, neutrophil engraftment (defined as absolute neutrophil count ≥ 500/μL), mean dose of fentanyl used, incidences of infections, and type of transplant. Supersaturated calcium phosphate rinses at 4 times/day were started for prevention of mucositis as soon as a patient was admitted. All patients also received betadine mouth gargles for oral hygiene. RESULTS Our study group included 42 autologous and 38 allogeneic hematopoietic stem cell transplant patients. Grade 1, 2, 3, and 4 mucositis levels were seen in 1, 19, 26, and 31 patients. We found no differences between our study group and historical control regarding parameters studied. Grade of mucositis was statistically significant (P < .01) when autologous transplant for myeloma was compared with autologous transplant for other diagnoses. CONCLUSIONS Supersaturated calcium phosphate rinses were ineffective in the management of mucositis associated with autologous and allogeneic bone marrow transplant.

Abstract
Delhi is the second largest city of the world both in terms of population and area, as well as being the capital of India. Every year, thousands of people from different states throng to the capital in search of a job in order to earn a living. When these people die and their bodies are found without any identifying documentation, it is very difficult for the police to establish their identities. These bodies are labelled as unidentified/unclaimed or unknown, and are sent for usually sent for medicolegal autopsy. Invariably, skeletonised bodies are also recovered, which are also subjected to medicolegal autopsy. Female foeticide is another social problem, and whenever such foetuses are disposed of illegally, they are also grouped under this category and brought for medicolegal autopsy. We undertook a five-year retrospective analysis (for the period 2010-2014) of all such cases brought for medicolegal autopsy at our centre, which caters only for the south and south-east districts of Delhi. A total of 7964 cases were brought for medicolegal autopsy, of which unknown cases accounted for about 16%. About 25-30 foetuses and skeletonised bodies were brought each year that was studied. The manner of death was certified as natural in about 71% of cases, with predominant pathology in the lungs. There was a clear predominance of males over females, with the 31- to 50-year age group accounting for half of all cases. There was an increase in the number of deaths during months of extreme temperatures. The average time between the recovery of a body by the police and the post-mortem was about seven days. These findings raise many questions, including the failure of governmental policies, police investigating agencies and social menace. The creation of a national missing-persons database as well as a DNA databank is needed to aid in the identification of unidentified/unclaimed and unknown bodies.

Abstract
In the present study, we have analyzed various biochemical and histopathological biomarkers in the Oreochromis mossambicus collected from 18 sites at Bhima River. The biochemical biomarkers viz. antioxidative enzymes in muscle viz. catalase, SOD, and GST, glycolytic enzymes in kidney viz. LDH and MDH, protein metabolic enzymes in liver, gill, brain, gonad and muscle viz. ALT and AST, neurotransmitter enzymes in muscle AChE, lipid peroxidation and histopathology in the liver and gill have been evaluated. The oxidative biomarkers, glycolytic enzymes, protein metabolic enzymes and lipid peroxidation were significantly (p<0.01) higher and AChE in muscle were significantly inhibited (p<0.01) in fishes from different sampling sites. The histopathology of the liver and gill were altered at different sampling sites. The liver histopathology showed hepatocytes vacuolization, haemorrhage, karyokinesis, necrosis, pyknotic nuclei, dilation of sinusoids and hepatocyte granular degeneration and in the gill histopathology showed distal lamellar gill tissue, diffuse epithelial hyperplasia and multifocal mucus cell hyperplasia, extensive edema of epithelial cells, blood congestion and edema in secondary lamellae. All the indicators are giving strong signals for contamination of the aquatic water bodies. The Bhima River is surrounded by several cities and agriculture land indicates that vigorous industrial activity coupled with intensive use of chemicals in agricultural practices may held. Therefore, based on our results, we could recommend that the investigated tissue and cell alterations may be successfully applied as reliable biomarkers for monitoring contaminated freshwater ecosystems. This study suggests that, the importance of antioxidative enzymes, cellular biomarkers, AChE, and histopathology used as biomarkers in aquatic ecosystem biomonitoring.

Abstract
INTRODUCTION Emerging virulent strains of influenza virus pose a serious public health threat with potential pandemic consequences. A novel avian influenza virus, H7N9, breached the species barrier from infected domestic poultry to humans in 2013 in China. Since then, it has caused numerous infections in humans with a close contact to poultry. MATERIALS AND METHODS In this study, we describe the preliminary characterisation of five murine monoclonal antibodies (MAbs) developed against recombinant haemagglutinin (rHA) protein of avian H7N9 A/Anhui/1/2013 virus by their Western blot and enzyme-linked immunosorbent assay (ELISA) reactivity and binding affinity. RESULTS Of the five MAbs, four were highly specific to H7N9 HA and did not show any cross-reactivity in ELISA with rHA protein from pandemic as well as seasonal H1N1, H2N2, H3N2, H5N1 and influenza virus B (B/Brisbane/60/2008). However, one of the MAbs, MA-24, in addition to HA protein of H7N9 also reacted strongly with HA protein of H3N2 and weakly with HA of pandemic and seasonal H1N1 and H2N2. All the five MAbs also reacted with H7N9 rHA in Western blot. The MAbs bound H7N9 rHA with an equilibrium dissociation constant (KD) ranging between 0.14 and 25.20 nM, indicating their high affinity to HA. CONCLUSIONS These antibodies may be useful in developing diagnostic tools for the detection of influenza H7N9 virus infections.

Abstract
INTRODUCTION Intracranial meningiomas are the second most common tumor of the CNS. The high-grade tumors are atypical and malignant meningioma comprising 5-7% and 1-3% of all meningiomas. The high-grade meningioma have an aggressive histopathological and clinical behavior. MATERIALS AND METHODS We retrospectively reviewed 37 patients of high-grade meningioma treated in our institute from 2002 to 2011. Clinical characteristics and treatment modality in form of surgery and radiotherapy (RT) were noted. Statistical analysis was done with regards to progression-free survival (PFS) and overall survival (OS) using Kaplan-Meier survival analysis. RESULTS The median age of the patients was 45.0 years. The median duration of symptoms was 6 months. Headache was the most common presenting symptom. Fourteen patients underwent complete excision, while 23 had subtotal excision. Twenty-two patients had World Health Organization (WHO) grade II histology tumors and 15 patients had grade III histology. Median RT dose delivered was 50 Gy for grade II tumors and 54 Gy for grade III tumors. Five-year PFS for grade II and III tumors was 58 and 20%, respectively. Five-year OS for grade II and III tumors was 83 and 23%, respectively. CONCLUSIONS High-grade meningiomas represent a rare and aggressive neoplasm. The mainstay of therapy is gross total resection (GTR) at the initial surgery. Postoperative adjuvant RT should be offered to all patients, regardless of the degree of resection achieved. Long-term follow-up is important as local recurrences and progression can develop years after the initial treatment.

Abstract
The GRAPES-3 tracking muon telescope in Ooty, India measures muon intensity at high cutoff rigidities (15-24 GV) along nine independent directions covering 2.3 sr. The arrival of a coronal mass ejection on 22 June 2015 18:40 UT had triggered a severe G4-class geomagnetic storm (storm). Starting 19:00 UT, the GRAPES-3 muon telescope recorded a 2 h high-energy (∼20 GeV) burst of galactic cosmic rays (GCRs) that was strongly correlated with a 40 nT surge in the interplanetary magnetic field (IMF). Simulations have shown that a large (17×) compression of the IMF to 680 nT, followed by reconnection with the geomagnetic field (GMF) leading to lower cutoff rigidities could generate this burst. Here, 680 nT represents a short-term change in GMF around Earth, averaged over 7 times its volume. The GCRs, due to lowering of cutoff rigidities, were deflected from Earth's day side by ∼210° in longitude, offering a natural explanation of its night-time detection by the GRAPES-3. The simultaneous occurrence of the burst in all nine directions suggests its origin close to Earth. It also indicates a transient weakening of Earth's magnetic shield, and may hold clues for a better understanding of future superstorms that could cripple modern technological infrastructure on Earth, and endanger the lives of the astronauts in space.

Abstract
The study presents a retrospective analysis of 64 cases of death resulting from ingestion of corrosive substances. The cases represented approximately 0.4% of all autopsies conducted and 13.6% of all fatal poisonings studied during the 10-year period from January 2005 to December 2014 at the Department of Forensic Medicine, All India Institute of Medical Sciences (AIIMS), New Delhi. The data was analyzed with regard to age, sex, nature and source of corrosive substance used, survival period, cause and manner of death. Males (64.06%) outnumbered females (35.94%), with a male-to-female ratio of 1.78:1. The most common age group involved was 21-30 years (35.94%). Sulfuric acid (68.75%) presented as the most common corrosive substance ingested. Household cleaning substances (39.06%) were identified as a common source of such type of corrosive substance, but the exact source could not be identified in 56.26% of cases. In the majority of cases (46.88%) death was due to perforation peritonitis. Most of the victims (54.69%) succumbed to their injuries within a day of ingestion. In 87.5% of cases, the corrosive substance was consumed for suicidal purposes. A strict regulatory framework is required for the production, distribution, storage and use of corrosive substances. Preventive guidelines and creating awareness among the masses will go a long way towards curbing such unfortunate incidents.

Abstract
Suicide by inhalation of carbon monoxide is not uncommon and usually involves car exhausts or burning charcoal or defective boilers. We report a case of a 25-year-old man, who committed suicide by inhaling carbon monoxide gas inside a polythene bag in a bathroom. The open carbon monoxide cylinder found inside the polythene bag was purchased online by the deceased a few days earlier. He had stated that the gas would be used for his experiment on the environment. A suicide note recovered from his trouser pocket revealed his intention for a painless death.

Abstract
The differences or similarities among different isolates of Trypanosoma evansi through endonuclease profile was identified in the present study. The repetitive nuclear DNA of T. evansi isolated from infected cattle, buffalo and equine blood was initially amplified by PCR using specific primers. A panel of restriction enzymes, EcoRI, Eco91l, HindIII and PstI were for complete digestion of PCR products. Agarose gel electrophoresis of digested product did not show cleavage fragments and only single DNA band of the original size was visible in the ethidium bromide stained agarose gel. This indicated that the 227 bp PCR product from repetitive sequence had no site-specific cleavage sites for the REs used in this study. No heterogeneity in the repetitive nuclear DNA restriction endonuclease profile among the different isolates was recorded.

Abstract
This study investigated 96h median lethal concentration of endosulfan (99%, pure α: β ratio of 7:3) by conducting static non-renewable acute toxicity bio-assay in Chanos chanos juvenile with average weight (110±5.65g). Further, the effect of different definitive doses (18.5, 19.5, 20.5, 21.5 and 22.5µg/L) of endosulfan on metabolic, heamato-immunoligcal and histopathological response were probed. Anti-oxidative enzymes CAT, SOD and GST showed significant (p<0.01) increase of activity in the liver, gill and brain during exposure to endosulfan in a dose and time dependent manner. The brain AChE activity showed significant (p<0.01) inhibition from 18.5 to 22.5µg/L exposure of endosulfan than the control group. LDH and MDH activity gradually increased with consequent increasing dose of endosulfan exposure in the liver, gill and brain. Similarly, ALT, AST and G6PDH activities in both liver and gill increased with consequent increases in the dose of endosulfan exposure. Immunological profile such as blood glucose and serum cortisol level significantly enhanced while respiratory burst activity declined with consequent increasing doses of endosulfan exposure. Histopathological alteration in the gill demonstrated curling of secondary lamellae, thickening of primary epithelium, shorting of secondary lamellae, epithelial hyperplasia, fusion of secondary lamellae, aneurism, and collapsed secondary lamellae due to dose dependent exposure of endosulfan. Liver histology illustrated cloudy swelling and necrosis with pyknotic nuclei to the moderate dose of endosulfan, whereas higher dose of endosulfan (21.5µg/L) displayed severe necrosis of hepatic cells. Overall results clearly indicate that acute exposure of endosulfan led to pronounced deleterious alterations on biochemical, heamato-immunological, and histopathological responses of C. chanos juvenile.

Abstract
Purpose: To evaluate the role of image-guided fine-needle aspiration cytology (FNAC) of deep-seated lymph nodes. Material and Methods: Image-guided FNACs were performed on 242 patients of deep-seated lymph nodes which included thoracic, retroperitoneal and abdominal nodes. A sterile 3.5/5-MHz micro convex sector probe was used for localisation of the node. The FNAC was performed using a 0.7- to 0.9-mm needle with the stylet removed and attached to a 20-ml syringe and FNAC handle after the needle was visualised in the lesion. For each case a minimum of 4-5 smears were made, and two observers without bias interpreted the smears. Results: A total of 242 patients were aspirated, of which 216 (90%) aspirations were US-guided and the remaining 26 (10%) were CT-guided. Adequate material for cytologic diagnosis was obtained in 208 (86%) patients with a similar diagnostic accuracy. The aspirate material was non-representative or scanty in 34 (14%) patients. The most common cytological diagnosis was tuberculosis/consistent with tuberculosis seen in 108 (45%) patients followed by metastasis (17%) and reactive hyperplasia (10%). Non-Hodgkin lymphoma was diagnosed in 22 (9%) patients. All patients were briefly followed for a period of 1 1/2 to 2 years (mean 1 year). Conclusion: Image-guided FNAC has a pivotal role, and is a cost-effective tool for establishing tissue diagnosis as a primary investigative modality. It is also helpful and accurate in follow-up of patients with a known malignant disease, thereby avoiding surgical intervention.

Abstract
The objective of this study was to elucidate the relationship between outcomes from carotid endarterectomy (CEA) in patients with and without renal insufficiency. Carotid endarterectomy is one of the most commonly performed vascular procedures. The role of cardiac comorbidity in carotid endarterectomy has been extensively studied. The relationship between renal failure and surgical outcomes has also been studied for both coronary artery bypass grafting and lower extremity occlusive disease. However, the role of renal insufficiency in relationship to decision making regarding surgical intervention for carotid stenosis is not well defined. The authors hypothesized that the outcomes from CEA were negatively influenced by renal dysfunction. A retrospective review was made of consecutive CEAs performed at their institution from 1990 to 1995. Patients were grouped into 2 categories according to their renal function. Group A, 448 patients (90%) with creatinine level 1.8 mg/dL or less, and group B, 49 patients (10%) with creatinine levels more than 1.8 mg/dL. Data from patients on dialysis are presented but were excluded for the purpose of analysis. Included in the study were 497 patients with a mean age of 70 +8.9 and 74 +8.9 for groups A and B, respectively. Preoperative creatinine was 1.1 (±0.25) mg/dL for group A and 2.5 (+0.81) mg/dL for group B. Outcomes were as follows: perioperative cardiac events 5.4% vs 28.6%, stroke rates 2.7% vs 2.0%, and mortality rates 0.9% vs 8.2%, for groups A and B, respectively. At 60-month follow-up the stroke rates were 7.6% vs 6.1%, and the mortality rates 22.8% vs 59.2%, for groups A and B, respectively. While patients with chronic renal insufficiency have no increased risk of perioperative or long-term neurologic events, perioperative and long-term mortality rates are significantly increased. This significant reduction in survival should prompt a more cautious application of CEA in patients with increased creatinine.

Abstract
BACKGROUND Childhood injuries, especially the unintentional category of injuries, occur most commonly in the environment inside a child's home. The primary objective of the present study was to assess the presence of home hazards for childhood injuries in households in an urban resettlement colony in New Delhi. METHODS A community-based cross-sectional study was carried out in an urban resettlement colony in Delhi. A hazards assessment tool was used to check the presence of hazards in the houses. RESULTS A total of 225 households were included. It was seen that121 (53.7%) had a cooking stove within the reach of the child, and 190 (84.3%) had the gas pipe within reach. Fire hazard was seen in 84% of houses. About 78% of households did not have locked storage for chemicals. CONCLUSION The study revealed a significant burden of hazards for childhood injuries within their own homes, thus emphasizing the need for injury prevention interventions to reduce the number of hazards.

Abstract
Road crashes are the leading cause of unnatural death among children all over the world. India tops the global list of fatalities from road crashes and the rate is increasing every year. Children accounted for 6.1% of the total accidental deaths due to motor vehicle crashes in 2013 in India. Despite such high rates of child fatalities in motor vehicle crashes, there is currently no law in India regarding the use of child restraint systems, despite various studies demonstrating that failure to use child restraints is associated with increased fatal injury. According to the World Health Organisation, if correctly installed and used, child restraints reduce deaths among infants by approximately 70% and deaths among small children by 54–80%. It has been made compulsory by law to use child restraint systems in many developed countries such as USA, England, Australia and Canada, but developing countries like India, lack such laws. We report a motor vehicle crash wherein a two-month-old male baby was travelling unrestrained on his mother’s lap in the rear of a car driven by the child’s uncle who was wearing a seatbelt. The crash proved fatal for the baby, who suffered a severe head injury, while the other two occupants of car, both adults, escaped the crash with minor injuries. Child fatality may have been avoided by the use of proper child restraint systems. Strict implementation of existing laws, formulation of new laws regarding child safety and public awareness are necessary to reduce child fatalities in road crashes. Along with this case report are discussed the existing laws of child restraint systems all over the world and the need for implementation of such laws in developing countries like India.

Abstract
Foeticide and the abandonment of newborns are important, albeit frequently neglected, issues. Concealment of childbirth is often seen in the setting of unwanted pregnancy which has been recognised as one of the most important factors in both cases. This study highlights the medico-legal autopsy findings of 238 abandoned foetuses and newborns over a period of 17 years (1996-2012) from the region of South Delhi, India. There was no sex predilection. The majority of the cases were full term. Nearly 35% of the foetuses were still born, about 29% were live born and the remainder were non-viable. Among the live born, death by homicide was more common than a natural death and most were left by the roadside. The abandoning and killing of newborns needs urgent attention, and strict measures are needed to save thousands of innocent lives.

Abstract
Background. Chronic obstructive pulmonary disease (COPD) is a preventable and treatable disease with serious impact on quality of life (QoL). There are limited studies available supporting coexistence of sino-nasal involvement in COPD. Methods. A prospective study was conducted to evaluate sino-nasal status in patients with COPD (n=100) presenting to the Department of Respiratory Medicine, Mahatma Gandhi Medical College and Hospital, Jaipur from July 2011 to October 2012. COPD was diagnosed based on the Global initiative on Obstructive Lung Disease (GOLD) guidelines. Sino-nasal status was assessed by detailed history, radiograph of the para-nasal sinuses (PNS), nasal endoscopy and mucociliary clearance time. Results. Sino-nasal symptoms were present in 74 patients with COPD; nasal discharge (75.7%) being the most common. Tobacco smokers with COPD had a higher occurrence of sino-nasal symptoms (76.8%). Radiograph of para-nasal sinuses showed that maxillary sinus was most commonly involved. Nasal endoscopy revealed discharge in 63.5% cases. Nasal mucociliary clearance time was delayed (>11 to >40 min) in 98% cases. Nasal mucociliary clearance time was significantly delayed (>20 min) in COPD patients who were tobacco smokers as compared to non-smokers (53.7% versus 16.7%) and also related with increasing severity of COPD. Conclusions. Our observations suggest that sino-nasal involvement and delayed mucociliary clearance are common in patients with COPD, especially in tobacco smokers. Assessment of upper airway involvement in all the patients with COPD can help better therapeutic intervention and improvement in QoL.

Abstract
Silicon Photo-Multipliers (SiPMs) are increasingly becoming popular for discrete photon counting applications due to the wealth of advantages they offer over conventional photo-detectors such as photo-multiplier tubes and hybrid photo-diodes. SiPMs are used in variety of applications ranging from high energy physics and nuclear physics experiments to medical diagnostics. The gain of a SiPM is directly proportional to the difference between applied and breakdown voltage of the device. However, the breakdown voltage depends critically on the ambient temperature and has a large temperature co-efficient in the range of 40-60 mV/°C resulting in a typical gain variation of 3%-5%/°C [Dinu et al., in IEEE Nuclear Science Symposium, Medical Imaging Conference and 17th Room Temperature Semiconductor Detector Workshop (IEEE, 2010), p. 215]. We plan to use the SiPM as a replacement for PMT in the cosmic ray experiment (GRAPES-3) at Ooty [Gupta et al., Nucl. Instrum. Methods Phys. Res., Sect. A 540, 311 (2005)]. There the SiPMs will be operated in an outdoor environment subjected to temperature variation of about 15 °C over a day. A gain variation of more than 50% was observed for such large variations in the temperature. To stabilize the gain of the SiPM under such operating conditions, a low-cost, multi-channel programmable power supply (0-90 V) was designed that simultaneously provides the bias voltage to 16 SiPMs. The programmable power supply (PPS) was designed to automatically adjust the operating voltage for each channel with a built-in closed loop temperature feedback mechanism. The PPS provides bias voltage with a precision of 6 mV and measures the load current with a precision of 1 nA. Using this PPS, a gain stability of 0.5% for SiPM (Hamamatsu, S10931-050P) has been demonstrated over a wide temperature range of 15 °C. The design methodology of the PPS system, its validation, and the results of the tests carried out on the SiPM is presented in this article. The proposed design also has the capability of gain stabilization of devices with non-linear thermal response.

Abstract
BACKGROUND Knowledge about determinants of quality of life (QoL) in eosinophilic oesophagitis (EoO) patients helps to identify patients at risk of experiencing poor QoL and to tailor therapeutic interventions accordingly. AIM To evaluate the impact of symptom severity, endoscopic and histological activity on EoE-specific QoL in adult EoE patients. METHODS Ninety-eight adult EoE patients were prospectively included (64% male, median age 39 years). Patients completed two validated instruments to assess EoE-specific QoL (EoO-QoL-A) and symptom severity (adult EoE activity index patient-reported outcome) and then underwent esophagogastroduodenoscopy with biopsy sampling. Physicians reported standardised information on EoE-associated endoscopic and histological alterations. The Spearman's rank correlation coefficient was calculated to determine the relationship between QoL and symptom severity. Linear regression and analysis of variance was used to quantify the extent to which variations in severity of EoE symptoms, endoscopic and histological findings explain variations in QoL. RESULTS Quality of life strongly correlated with symptom severity (r = 0.610, P < 0.001). While the variation in severity of symptoms, endoscopic and histological findings alone explained 38%, 35% and 22% of the variability in EoE-related QoL, respectively, these together explained 60% of variation. Symptom severity explained 18-35% of the variation in each of the five QoL subscale scores. CONCLUSIONS Eosinophilic oesophagitis symptom severity and biological disease activity determine QoL in adult patients with eosinophilic oesophagitis. Therefore, reduction in both eosinophilic oesophagitis symptoms as well as biological disease activity is essential for improvement of QoL in adult patients. Clinicaltrials.gov number, NCT00939263.

Abstract
In this paper, we describe the thought process and initial data behind the development of an imaging platform (LeasyScan) combined with lysimetric capacity, to assess canopy traits affecting water use (leaf area, leaf area index, transpiration). LeasyScan is based on a novel 3D scanning technique to capture leaf area development continuously, a scanner-to-plant concept to increase imaging throughput and analytical scales to combine gravimetric transpiration measurements. The paper presents how the technology functions, how data are visualised via a web-based interface and how data extraction and analysis is interfaced through 'R' libraries. Close agreement between scanned and observed leaf area data of individual plants in different crops was found (R(2) between 0.86 and 0.94). Similar agreement was found when comparing scanned and observed area of plants cultivated at densities reflecting field conditions (R(2) between 0.80 and 0.96). An example in monitoring plant transpiration by the analytical scales is presented. The last section illustrates some of the early ongoing applications of the platform to target key phenotypes: (i) the comparison of the leaf area development pattern of fine mapping recombinants of pearl millet; (ii) the leaf area development pattern of pearl millet breeding material targeted to different agro-ecological zones; (iii) the assessment of the transpiration response to high VPD in sorghum and pearl millet. This new platform has the potential to phenotype for traits controlling plant water use at a high rate and precision, of critical importance for drought adaptation, and creates an opportunity to harness their genetics for the breeding of improved varieties.

Abstract
This study aimed at developing a model for predicting the formation of trihalomethanes (THMs) in drinking water supplies. Monitoring of THMs in five major water treatment plants situated in the Eastern part of India revealed high concentration of THMs (231-484 μg l(-1)). Chloroform was predominant, contributing 87-98.9% to total THMs. Seasonal variation in THMs levels dictated that the concentration were higher in autumn than other seasons. Linear regression analysis of data indicated that TOC is the major organic precursors for THMs formation followed by DOC and UV254. Linear and non-linear predictive models were developed using SPSS software version 16.0. Validation results indicated that there is no significant difference in the predictive and observed values of THMs. Linear model performed better than non-linear one in terms of percentage prediction errors. The model developed were site specific and the predictive capabilities in the distribution systems vary with different environmental conditions.

Abstract
Background: Intracranial meningiomas are the second most common tumor of the central nervous system. Grade I tumors are the most common variety of meningioma and have a benign course. Surgery is the mainstay of treatment. Radiotherapy (RT) decreases the local recurrence rates and progression in patients with subtotal excision (STE). The authors present our institute's experience in combined modality management of 18 successive patients of Grade I meningioma. Materials and Methods: We retrospectively reviewed 18 patients of Grade I meningioma treated in our institute from 2003 to 2011. Clinical characteristics and treatment modality in form of surgery and RT were noted. Statistical analysis was done with regards to recurrence free survival and overall survival using Kaplan–Meier survival analysis. Results: The median age of the patients was 52.5 years. Seven patients were males and 11 patients were females. The median duration of symptoms was 8 months. Headache was the most common presenting symptom followed by vomiting, seizures, motor weakness and visual deficits. Five patients underwent complete excision while 13 had STE. 11 patients received early RT while 5 patients received RT at recurrence. Median RT dose delivered was 50 Gy. RT had significant effect on local control especially in subtotal resections, with overall 93.75% local control rates. Conclusions: Grade I meningiomas represent a benign neoplasm. The mainstay of therapy is gross total resection at the initial surgery. Postoperative adjuvant RT should be offered to patients with subtotal resection. Long-term follow-up is important as local recurrences and progression can develop years after the initial treatment.

Abstract
OBJECTIVES Both renal disease and systemic inflammation predict non-AIDS-defining events and overall mortality in HIV-infected patients. Here, we sought to determine the relationships between renal disease and circulating inflammation markers. METHODS We performed a secondary analysis of AIDS Clinical Trials Group Study A5224s to determine if markers of renal disease [urine protein:creatinine ratio (uPCR), urine albumin:creatinine ratio (uACR), and estimated glomerular filtration rate (eGFR), using Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) creatinine and cystatin C-creatinine] were associated with markers of systemic inflammation [high-sensitivity C-reactive protein, interleukin-6, tumour necrosis factor (TNF)-α, soluble TNF-α receptor I (sTNFRI), sTNFRII, and soluble vascular cellular and intercellular adhesion molecules]. We correlated these renal and inflammatory markers prior to antiretroviral initiation and after 96 weeks of therapy. RESULTS We found that eGFR (estimated using CKD-EPI cystatin C-creatinine), uPCR, and uACR were significantly correlated with most assessed markers of systemic inflammation prior to antiretroviral initiation. uPCR and eGFR (using CKD-EPI cystatin C-creatinine), but not uACR, remained significantly correlated with most of the assessed inflammatory markers after 96 weeks of antiretroviral therapy (ART). Most of these correlations, although statistically significant, were < 0.50. eGFR using CKD-EPI creatinine was much less frequently associated with inflammation markers and only significantly correlated with sTNFR1 at week 0 and with sTNFRI and II at week 96. CONCLUSIONS Renal disease and function were associated with systemic inflammation in HIV infection, both before and after ART. Systemic inflammation may partially explain the relationships between proteinuria, albuminuria, and reduced renal function and future adverse outcomes.

Abstract
Collective cell migration often involves notable cell-cell and cell-substrate adhesions and highly coordinated motion of touching cells. We focus on the interplay between cell-substrate adhesion and cell-cell adhesion. We show that the loss of cell-surface contact does not significantly alter the dynamic pattern of protrusions and retractions of fast migrating amoeboid cells (Dictyostelium discoideum), but significantly changes their ability to adhere to other cells. Analysis of the dynamics of cell shapes reveals that cells that are adherent to a surface may coordinate their motion with neighbouring cells through protrusion waves that travel across cell-cell contacts. However, while shape waves exist if cells are detached from surfaces, they do not couple cell to cell. In addition, our investigation of actin polymerization indicates that loss of cell-surface adhesion changes actin polymerization at cell-cell contacts. To further investigate cell-cell/cell-substrate interactions, we used optical micromanipulation to form cell-substrate contact at controlled locations. We find that both cell-shape dynamics and cytoskeletal activity respond rapidly to the formation of cell-substrate contact.

Abstract
INTRODUCTION An understanding of the epidemiological trend in hospital admissions, including morbidity and mortality patterns and the economic impact, is critical for healthcare planning and appropriate resource allocation. As we find very few literature on the pattern of paediatric admissions outside Kathmandu Valley, it is essential to conduct studies in the various parts of the country to determine the paediatric inpatient burden as well resource allocations. METHODS A retrospective study was carried out at Department of Pediatrics, College of Medical Sciences-Teaching Hospital, Bharatpur, Chitwan, Nepal over a period of one year. All the admissions were analyzed for age, sex, address, seasonal variation, frequency of diseases according to the organ system involved, duration of hospital stay, and the outcome. RESULTS Out of the total 814 cases admitted 68.8% of the patients were younger than five years. There was male preponderance with male to female ratio of 1.9:1. Majority (43.6%) admissions were from Chitwan itself. Respiratory, gastrointestinal and neurologic conditions were the main cause for admission. The mean duration of hospital stay was 5.28 days and the mortality was only 0.1%. CONCLUSIONS In this study under five-year patients contributed to 2/3rd of the hospital admissions. Respiratory, gastrointestinal and neurologic conditions were the main cause for admission with pneumonia, URTI and acute gastroenteritis being the most common diseases.

Abstract
The lifetime cancer risk and the hazard index of trihalomethanes (THMs) through oral ingestion, dermal absorption, and inhalation exposure from supply water of five WTPs were analysed. THMs concentration varied from plant to plant and was found to be in the range of 274-511µg/l, which is much higher than the prescribed USEPA standards of 80µg/l. Chloroform was the most dominant THM followed by bromodichloromethane (BDCM), and dibromochloromethane (DBCM). Cancer risk analysis through multi-pathways exposure reveals that residents had a higher cancer risk through oral ingestion than other two routes of exposure. The lifetime cancer risks of THMs from supply water were 100 times higher than prescribed USEPA guidelines. The higher cancer risk found for Indian context than those reported for other countries like USA, UK, Japan, Australia, is mainly due to the higher concentration level of THMs, water intake and average body weight. The study also revealed that amongst different THMs, chloroform is the major THMs causing cancer risk through both oral and dermal route of exposure whereas in case of inhalation it was mainly because of BDCM. Average lifetime cancer risk analysis indicated that females are more prone to cancer risk than males. Oral ingestion is a major route indicating the potential impact of non-cancer risk while it was insignificant through dermal exposure. Sensitivity analysis of THMs revealed that chloroform is the predominant parameter followed by body weight and exposure duration influencing cancer risk.

Abstract
Filicide-suicide is a special category of homicide-suicide event where the victim(s) are children and the perpetrator is one of the parents or both. It is not extensively documented or adequately defined in literature. In developed countries, shooting is a common method of homicide and suicide. Uses of knives, blunt objects, strangulation, poisoning and drowning are other methods frequently employed by the perpetrator. Homicide by hanging in filicide-suicide is rarely reported in forensic literature. We present a rare case of filicide-suicide, where the mother killed both her children by hanging them one by one from a ceiling fan in the same room and later committed suicide by hanging in another room.

Abstract
This is a novel report in which chromosomal position of the rice blast resistance gene Pi54 was not found to affect significantly the resistance phenotype or morphological traits. Blast disease caused by Magnaporthe oryzae is a serious constraint in rice production at global level. Pi54 gene imparts resistance against M. oryzae. Three different transgenic lines containing Pi54 and its orthologue Pi54rh were shown to be resistant to different races of M. oryzae. To determine the chromosomal location of Pi54 gene in transgenic lines, inverse PCR was performed. Our analysis showed that in two transgenic lines, Pi54 gene was integrated on chromosomes 6 and 10 at 12.94 and 22.30 Mb, respectively. Similarly, Pi54rh allele was integrated on chromosome 1 at 16.25 Mb. The Pi54 gene present on chromosome 6 was located in a non-coding region whereas in the other TP-Pi54 line, the gene was introgressed on chromosome 10 in between the coding region of SAP domain gene. The Pi54rh was also located in the non coding region flanked by the retrotransposon genes. These rice lines were evaluated for eight different traits related to seed and plant morphology and agronomic features for two consecutive years. The transgenic lines containing Pi54 gene have higher tiller number, grain weight, epicotyl length, and yield compared to the non-transgenic control. Multivariate correlation analysis shows that blast resistance was positively correlated with the number of tillers; thousand grain weight and epicotyl length. These results will facilitate precise utilization of Pi54 gene and its orthologue in breeding programs for the development of rice cultivars with broad spectrum and durable resistance to M. oryzae.

Abstract
In the present work, we report on the investigation of low-temperature (300-5 K) thermoelectric properties of hot-pressed TiSe2, a charge-density-wave (CDW) material. We demonstrate that, with increasing hot-pressing temperature, the density of TiSe2 increases and becomes nonstoichiometric owing to the loss of selenium. X-ray diffraction, scanning electron microscopy, and transimission electron microscopy results show that the material consists of a layered microstructure with several defects. Increasing the hot-press temperature in nonstoichiometric TiSe2 leads to a reduction of the resistivity and enhancement of the Seebeck coefficient in concomitent with suppression of CDW. Samples hot-pressed at 850 °C exhibited a minimum thermal conductivity (κ) of 1.5 W/m·K at 300 K that, in turn, resulted in a figure-of-merit (ZT) value of 0.14. This value is higher by 6 orders of magnitude compared to 1.49 × 10(-7) obtained for cold-pressed samples annealed at 850 °C. The enhancement of ZT in hot-pressed samples is attributed to (i) a reduced thermal conductivity owing to enhanced phonon scattering and (ii) improved power factor (α(2)σ).

Abstract
In this paper we report the thermoelectric performance of Sr intercalated TiSe(2) above 300 K. Refined x-ray diffraction, high resolution transmission electron microscopy and scanning electron microscopy images show well oriented polycrystalline grains along a (0 0 l) direction and layered growth of the sample. Intercalation of Sr in TiSe(2) shows an improved Seebeck coefficient (α) value without altering the polarity of the majority charge carrier. A drastic reduction in the thermal conductivity (κ) from 3.8 W m K(-1) to 1.2 W m K(-1) (at 650 K) was observed which is ascribed to the: (i) scattering of the phonon by natural layer interfaces, grain boundaries and lattice defects and (ii) rattling of intercalated Sr atoms among weakly bound TiSe(2) layers. This led to the maximum ZT of ~0.08 at 650 K for Sr(x)TiSe(2) (x > 0.1) which is almost twice as high as the parent TiSe(2).

Abstract
INTRODUCTION Birth asphyxia is a serious clinical problem worldwide. It claims approximately 9 million deaths each year. It can lead to serious neurological sequaele, such as cerebral palsy, mental retardation, and epilepsy. METHODS All babies admitted in College of Medical Sciences Teaching Hospital, Chiwan, Nepal, NICU from January 2013 to December 2013 with a diagnosis of birth asphyxia (5 min Apgar<7 or those with no spontaneous respirations after birth) were included in the study (n=125). This was a descriptive observational study. Clinical information was collected (gravida, hour at presentation, mode of delivery, sex of baby, gestational age of the baby, requirement of resuscitation). Neonates were admitted to NICU, observed for complications and managed as per hospital protocol. RESULTS Among the 722 neonates admitted to NICU, 125 had perinatal asphyxia (17.3%). Babies with Hypoxic ischemic encephalopathy(HIE) Grade I had a very good outcome but HIE III was associated with a poor outcome. Outborn neonates had higher grades of perinatal asphyxia as compared to inborns (p=0.018). Term gestation, Males and Multigravida were associated with a higher rate of birth asphyxia. 22.4% neonates were delivered via caesarean section and 74.4% required bag and mask ventilation at birth. CONCLUSIONS Birth asphyxia was one of the commonest causes of admission NICU. Babies with HIE Grade III had a very poor prognosis. Outborn neonates with birth asphyxia had a higher mortality. Males were frequently affected than females.

Abstract
Additive manufacturing (AM) has the potential to create geometrically complex parts that require a high degree of customization, using less material and producing less waste. Recent studies have shown that AM can be an economically viable option for use by the industry, yet there are some inherent challenges associated with AM for wider acceptance. The lack of standards in AM impedes its use for parts production since industries primarily depend on established standards in processes and material selection to ensure the consistency and quality. Inability to compare AM performance against traditional manufacturing methods can be a barrier for implementing AM processes. AM process sustainability has become a driver due to growing environmental concerns for manufacturing. This has reinforced the importance to understand and characterize AM processes for sustainability. Process characterization for sustainability will help close the gaps for comparing AM performance to traditional manufacturing methods. Based on a literature review, this paper first examines the potential environmental impacts of AM. A methodology for sustainability characterization of AM is then proposed to serve as a resource for the community to benchmark AM processes for sustainability. Next, research perspectives are discussed along with relevant standardization efforts.

Abstract
Multilocus sequence typing (MLST), a sequence-based typing method for bacterial pathogens, is currently the best method for long-term epidemiological study and to understand the population structure of the bacteria. This investigation was carried out to study the diversity of Pasteurella multocida isolates circulating in India. Ten different sequence types (ST) identified in this study are ST 122 from cattle, goat, mithun and pig; ST 50 from pig; ST 9 from cattle and sheep; ST 229 from cattle and goat; ST 71 and ST 277 from cattle; and ST 129, ST 280, ST 281 and ST 282 from avian species. Of these, ST 277, ST 280, ST 281 and ST 282 were identified for the first time. The analysis of results provides novel epidemiological information on the circulation of multiple STs across India. The majority of STs or their variants identified in this study have already been reported from different parts of the globe. This suggests that probably transboundary spread of strains across countries and continents has occurred across evolutionary time and is still happening. The isolation of ST 122 from small ruminants and pigs suggests that these species may be included in the preventive vaccination policy for effective control of haemorrhagic septicaemia in India.

Abstract
The present manuscript reports the characterization, optimization of rheological properties, and loading and release capabilities of 5'-GMP mediated β-FeOOH hydrogel. Circular dichroism (CD) analysis indicates it to contain mainly the left-handed helix similar to that of Z-DNA. The highest viscosity (>300 cP) corresponds to the sample containing 2.5 × 10(-3) mol dm(-3) of 5'-GMP (SP2H). Field emission scanning electron microscope (FESEM) and transmission electron microscope (TEM) studies indicate the freeze-dried (FD) SP2H to be porous in nature, which is also supported by its high Brunauer-Emmett-Teller (BET) surface area of 226 m(2)/g as compared to that of SP3H (75 m(2)/g). Selected area electron diffraction (SAED) analysis and Raman spectroscopy show it to contain β-FeOOH phase. The FD SP2H exhibits the high swelling ratio (326%) and loading capacity for methylene blue (MB) dye. It displays a controlled and efficient release (>90%) for optimized [MB] (2.5 × 10(-4) mol dm(-3)) in 48 h. The low toxicity of as synthesized FD SP2H nanostructures against MDA-MB-231 (breast cancer cells) up to 100 μg/mL suggests its biocompatible nature. The high porosity, surface area, % swelling, and loading and release performance of the hydrogel indicate its potential for drug delivery and other biological applications.
