TO EVALUATE THE MORPHOLOGICAL AND MORPHOMETRIC FEATURES OF ADULT HUMAN CADAVERIC RIGHT LUNG IN NORTH INDIAN POPULATION

Objectives: In the present study, different morphological and morphometric features of adult human cadaveric right lungs were observed and noted on the predesigned pro forma. Not much of such measurements have been done in the past. The mean values and standard deviations are calculated. The data thus obtained were tabulated scrutinized, analyzed, and compared with the earlier studies wherever possible. If any variant from the normal is observed, an attempt has been made to explain the same on ontogenic or phylogenic basis. Methods: The present study has been conducted on 50 adult human cadaveric right lungs obtained from embalmed cadavers, used for dissection in the department of Anatomy, Govt. Medical College, Amritsar, formed the material for the current study. Results: Majority of the lungs (49 [98%]) were spongy in texture while 1 (2%) lung was firm to touch. It is evident that majority of lungs depicted mottling in the form of black, brown or grey in color in 38%, 28%, and 26% of the specimens, respectively. A complete grey, brown, or brownish black color was seen in 2% lungs each. In one lung yellow mottling was seen which could be because of fat deposition. Length of posterior border (19.9cm) was more as compared to anterior border (17.8 cm). Lungs were measured both along lateral and medial surfaces. Along the lateral surface its mean value was 18.52±3.178 cm (Range 12–25 cm) while along medial surface its mean value was 15.11±2.241 cm (Range 9–23 cm). The mean AP width of right lung at center was 11.05±2.864 cm (Range 7–23 cm) and along inferior border was 13.26±2.743 cm (Range 9–20 cm). The mean mediolateral width was found to be 7.536±2.318 cm with range being 4–15.2 cm. Conclusion: Knowledge of normal measurements of lungs and their variations may help cardiothoracic surgeons to avoid undue complications during surgery. Furthermore, it may help radiologist to resolve perplexed radiographic findings

Diagnostic spectrum of CSF involvement by malignant cells: three-year experience of tertiary care hospital in CSF cytology

Background: Cerebrospinal fluid (CSF) cytology is the diagnostic gold standard test for primary or metastatic involvement of central nervous system (CNS) by malignancy. It is a very important and routinely done test in the laboratory but its sensitivity is low due to many confounding factors and varies amongst type of malignancies. We did retrospective analysis of CSF cytology carried out at our center from January 2013 to December 2015 to find out about spectrum of malignancies being detected on CSF cytology.Methods: From January 2013 to December 2015, three hundred and seventy-five CSF samples were received and processed for presence of malignant cells at our center. The cytospin preparations stained with LG and PAP stains of these CSF samples were analyzed along with any special stain that was available in the records. Clinical details of the patients with positive cytology were correlated from records.Results: The diagnostic spectrum obtained through study of positive CSF cytology included cases of metastatic solid malignancies and hematolymphoid malignancies. Four cases out of ten were of Metastatic Adenocarcinoma with primary origin being Breast, Lung and Stomach. Out of six cases of hematolymphoid malignancies; five were known cases of lymphoma/leukemia and one was primarily diagnosed to have Non-Hodgkin’s lymphoma (NHL) on CSF cytology.Conclusions: Both Epithelial and Hematolymphoid malignancies can be diagnosed on CSF cytology and these are predominantly metastatic in origin; Hematolymphoid malignancies are more common in CSF than solid malignancies. Correlation with clinical details and Neuroimaging is a must

EBBIOT: A Low-complexity Tracking Algorithm for Surveillance in IoVT Using Stationary Neuromorphic Vision Sensors

In this paper, we present EBBIOT-a novel paradigm for object tracking using stationary neuromorphic vision sensors in low-power sensor nodes for the Internet of Video Things (IoVT). Different from fully event based tracking or fully frame based approaches, we propose a mixed approach where we create event-based binary images (EBBI) that can use memory efficient noise filtering algorithms. We exploit the motion triggering aspect of neuromorphic sensors to generate region proposals based on event density counts with >1000X less memory and computes compared to frame based approaches. We also propose a simple overlap based tracker (OT) with prediction based handling of occlusion. Our overall approach requires 7X less memory and 3X less computations than conventional noise filtering and event based mean shift (EBMS) tracking. Finally, we show that our approach results in significantly higher precision and recall compared to EBMS approach as well as Kalman Filter tracker when evaluated over 1.1 hours of traffic recordings at two different locations.Comment: 6 pages, 5 figure

Efficacy of fecal microbiota therapy in steroid dependent ulcerative colitis: a real world intention-to-treat analysis

Background/Aims Four high-quality randomized controlled trials have proven the efficacy of fecal microbiota transplantation (FMT) in active ulcerative colitis (UC). We assessed the efficacy of FMT in a real-world setting involving steroid-dependent patients with UC. Methods This was a single-center prospective analysis of data from steroid-dependent patients with UC treated with FMT from September 2015 to September 2017 at the Dayanand Medical College, a tertiary care center in India. Fecal samples from random unrelated donors were administered through colonoscopy at weeks 0, 2, 6, 10, 14, 18, and 22. The primary outcome was achievement of steroid-free clinical remission, and the secondary outcomes were clinical response and endoscopic remission at 24 weeks. Modified intention-to-treat analysis was performed, which included subjects who underwent at least 1 FMT. Results Of 345 patients with UC treated during the study period, 49 (14.2%) had steroid-dependent UC. Of these 49 patients, 41 underwent FMT: 33 completed 7 sessions over 22 weeks according to the protocol, and 8 discontinued treatment (non-response, 5; lost to follow-up, 2; and fear of adverse effects, 1). At week 24, steroid-free clinical remission was achieved in 19 out of 41 (46.3%) patients, whereas clinical response and endoscopic remission were achieved in 31 out of 41 (75.6%) and 26 out of 41 (63.4%) patients, respectively. All patients with clinical response were able to withdraw steroids. There were no serious adverse events necessitating discontinuation. Conclusions A multisession FMT via the colonoscopic route is a promising therapeutic option for patients with steroid-dependent UC, as it can induce clinical remission and aid in steroid withdrawal

To determine the prevalence of oral mucosal lesions and their association with pattern of tobacco

Aim: To determine the Prevalence of Oral mucosal lesions and their association with Pattern of tobacco. Methods: Following ethical approval, a descriptive, cross sectional research with 200 participants was done at the department of oral pathology. Individuals aged 16 and up who visited the research location and were consulted for wilful involvement in the study were included. Personal interviews were used to collect demographic information as well as tobacco use status utilising a selfdesigned proforma. Tobacco consumption habits were broadly classified into four categories based on the following criteria: smokers were those who reported daily or less than daily use of smoked form of tobacco without use of smokeless tobacco, whereas smokeless tobacco users were those who reported daily or less than daily use of smokeless tobacco without use of smoked form of tobacco. Individuals who used both forms throughout the research were classified as dual users, whereas those who never used tobacco or had a history of quitting one or both kinds were classified as nontobacco users. Results: The study population consisted of 100 people, 70 percent of whom were men and 30 percent of whom were females, with a mean age of 47.41 10.52 years

Pricing Framework for a Differential Services Internet

A number of recent proposals and proposed standards have addressed adding differential services to the Internet. Although their details and tentative implementations differ, most are recommending what essentially amounts to multiple levels of best-effort service. In this paper, we survey recent differential services and pricing proposals and introduce a pricing framework for a differentiated-services network that focuses on simplicity, flexibility, and ease of implementation. In particular, our model can be used in the current heterogeneous Internet without major restructuring. We focus on flat-rate, per-time and usage-based pricing, where users can change their service level on an ad-hoc basis. We also show that a sender-pays model with back-charging is simple to implement and can be effective even in complicated transactions, such as multicasting. Our approach is different from many previous proposals and consciously integrates differential services and pricing with impleme..

Quenching of excited uranyl ion during its photochemical reduction by triphenylphosphine: Part V-Effect of covalently bonded and ionic halides

1093-1095Electron absorption spectroscopy has been used to measure bimolecular photophysical deactivation constant by exploiting photochemical reduction of uranyl ion with triphenylphosphine. Relative rates of bimolecular quenching follow the order SCN- > Cl- > CCl4 > CHCl3 > CH2Cl2 showing that free ionic halide and increasing number of chlorine atoms in covalently bonded alkyl halides increase the bimolecular quenching action. The increased availability of non-bonding electrons on halogen atom facilitate interaction with electron deficient species (excited uranyl ion)

Relative efficiencies of transient transformation of <em>Arabidopsis thaliana </em> and <em>Nicotianatabacum </em> upon heterologous expression of membrane proteins

195-198A cyanobacterial gene encoding a protein with multiple transmembrane helices, when transformed into Arabidopsis thaliana and Nicotianatabacum, demonstrated several differences in the relative responses of both the host species, particularly in efficiencies of regeneration of transformed tissue from leaf explants. The gene of interest (GOI) encoded an integral membrane protein containing 12 transmembrane helices and functioned as a sodium dependent inorganic ion transporter in a native cyanobacterium. Agrobacterium tumefaciens-mediated transformation was carried out by coculture method. The leaves of N. tabacum successfully regenerated into transformed callus tissue and gave positive results upon GUS assay; while the A. thaliana leaves did not give any transformed callus and, a few days post agro-infection, all the explants displayed tissue necrosis. The results obtained point towards A. thaliana's recalcitrance to Agrobacterium-mediated transformation by coculture method and the difficulty of expressing hydrophobic membrane proteins in heterologous systems
