    Get PDF
    Odontogenic fibromyxoma (OM) is a rare locally invasive, non metastasizing benign neoplasm found exclusively in the jaws. It commonly occurs in the second and third decade,and the mandible is involved more commonly than the maxilla. The lesion often grows without symptoms and presents as a painless swelling. The radiographic features are variable so the diagnosis is not easy in many cases. It posesa diagnostic and therapeutic challenge due to its morphology and biological behaviour. A caseo f OM of the maxilla with unusual radiographic and histological features is described in a 27 year old female

    Primary amyloidosis is a group of monoclonal plasma cell disorders, characterized by extracellular deposition of immunoglobulin light chain fibrils in multiple organs leading to progressive multiorgan dysfunction. It is a rare disease which usually occurs in elderly persons and has a poor prognosis. We report a 72-year-old male patient with chronic abdominal distension, bilateral pitting pedal edema with nephrotic range proteinuria and amyloid deposition in liver and bone marrow. Immunoelectrophoresis of serum demonstrated the presence of immunoglobulin light chains of the circulating monoclonal protein. He was treated with IV bortezomib and IV dexamethasone

    Get PDF
    The inlet casing inner has manufactured using Ti-6Al-4V alloy through a closed die-forging route. It undergoes cyclic loads in addition to operating in extreme conditions in high-temperature environments. The demanding mission requirement of these engines necessitates the inlet casing inner to be flawless throughout its life cycle while retaining its structural integrity. It makes the qualification for airworthiness of the casing, a daunting task. In addition, the qualification tests also help to evaluate the design and manufacturing processes (closed die forging) of the inlet casing inner. The tests also provide data for further improvement of the inlet casing inner in terms of strength and fatigue life. It helps to ensure that the inlet casing inner will be able to perform as expected throughout its operational life. All the batch and consolidated test results comply with the relevant ASTM, MIL standards, and test schedule requirements

    BACKGROUND: Neurodevelopmental disorders (NDDs) compromise the development and attainment of full social and economic potential at individual, family, community, and country levels. Paucity of data on NDDs slows down policy and programmatic action in most developing countries despite perceived high burden. METHODS AND FINDINGS: We assessed 3,964 children (with almost equal number of boys and girls distributed in 2-<6 and 6-9 year age categories) identified from five geographically diverse populations in India using cluster sampling technique (probability proportionate to population size). These were from the North-Central, i.e., Palwal (N = 998; all rural, 16.4% non-Hindu, 25.3% from scheduled caste/tribe [SC-ST] [these are considered underserved communities who are eligible for affirmative action]); North, i.e., Kangra (N = 997; 91.6% rural, 3.7% non-Hindu, 25.3% SC-ST); East, i.e., Dhenkanal (N = 981; 89.8% rural, 1.2% non-Hindu, 38.0% SC-ST); South, i.e., Hyderabad (N = 495; all urban, 25.7% non-Hindu, 27.3% SC-ST) and West, i.e., North Goa (N = 493; 68.0% rural, 11.4% non-Hindu, 18.5% SC-ST). All children were assessed for vision impairment (VI), epilepsy (Epi), neuromotor impairments including cerebral palsy (NMI-CP), hearing impairment (HI), speech and language disorders, autism spectrum disorders (ASDs), and intellectual disability (ID). Furthermore, 6-9-year-old children were also assessed for attention deficit hyperactivity disorder (ADHD) and learning disorders (LDs). We standardized sample characteristics as per Census of India 2011 to arrive at district level and all-sites-pooled estimates. Site-specific prevalence of any of seven NDDs in 2-<6 year olds ranged from 2.9% (95% CI 1.6-5.5) to 18.7% (95% CI 14.7-23.6), and for any of nine NDDs in the 6-9-year-old children, from 6.5% (95% CI 4.6-9.1) to 18.5% (95% CI 15.3-22.3). Two or more NDDs were present in 0.4% (95% CI 0.1-1.7) to 4.3% (95% CI 2.2-8.2) in the younger age category and 0.7% (95% CI 0.2-2.0) to 5.3% (95% CI 3.3-8.2) in the older age category. All-site-pooled estimates for NDDs were 9.2% (95% CI 7.5-11.2) and 13.6% (95% CI 11.3-16.2) in children of 2-<6 and 6-9 year age categories, respectively, without significant difference according to gender, rural/urban residence, or religion; almost one-fifth of these children had more than one NDD. The pooled estimates for prevalence increased by up to three percentage points when these were adjusted for national rates of stunting or low birth weight (LBW). HI, ID, speech and language disorders, Epi, and LDs were the common NDDs across sites. Upon risk modelling, noninstitutional delivery, history of perinatal asphyxia, neonatal illness, postnatal neurological/brain infections, stunting, LBW/prematurity, and older age category (6-9 year) were significantly associated with NDDs. The study sample was underrepresentative of stunting and LBW and had a 15.6% refusal. These factors could be contributing to underestimation of the true NDD burden in our population. CONCLUSIONS: The study identifies NDDs in children aged 2-9 years as a significant public health burden for India. HI was higher than and ASD prevalence comparable to the published global literature. Most risk factors of NDDs were modifiable and amenable to public health interventions

    Delineating Ecological Boundaries of Hanuman Langur Species Complex in Peninsular India Using MaxEnt Modeling Approach

    Hanuman langur is one of the widely distributed and extensively studied non-human diurnal primates in India. Until recently it was believed to be a single species - Semnopithecus entellus. Recent molecular and morphological studies suggest that the Hanuman langurs consists of at least three species S. entellus, S. hypoleucos and S. priam. Furthermore, morphological studies suggested that both S. hypoleucos and S. priam have at least three subspecies in each. We explored the use of ecological niche modeling (ENM) to confirm the validity of these seven taxa and an additional taxon S. johnii belonging to the same genus. MaxEnt modeling tool was used with 19 bioclimatic, 12 vegetation and 6 hydrological environmental layers. We reduced total environmental variables to 14 layers after testing for collinearity and an independent test for model prediction was done using ENMTools. A total of 196 non-overlapping data points from primary and secondary sources were used as inputs for ENM. Results showed eight distinct ecological boundaries, corroborating the eight taxa mentioned above thereby confirming validity of these eight taxa. The study, for the first time provided ecological variables that determined the ecological requirements and distribution of members of the Hanuman langur species complex in the Indian peninsula

    Not AvailableCrop residue burning is severe in rice–wheat cropping system of North-western states (Punjab, Haryana, Uttarakhand, and western Uttar Pradesh) of India, where mechanized harvesting of rice using combine harvesters is a common practice, and management of leftover residue in the short window of 10–15 days for timely sowing of wheat is a formidable task. Moreover, there is a lack of user-friendly, costeffective, and economically viable options and, around 23 million tonnes of rice residue is burnt annually in the region. Burning biomass not only pollutes environment but also results in loss of appreciable amount of plant’s essential nutrients. Straw burning releases soot particles, nitrogen oxides, sulphur dioxide, carbon dioxide, carbon monoxide, and polycyclic aromatic hydrocarbons, thus causing serious deterioration in atmospheric quality and human health hazards. We attempted to identify and quantify the environmental cost of paddy straw burning in North-west India. Using extant coefficients, it is estimated that cost of paddy residue burning is INR (Indian National Rupee) 8953 per ha, and the social cost of burning is INR 3199 crores per annum in the region.Not Availabl

    Antimicrobial effects of helix D-derived peptides of human antithrombin III

    Antithrombin III (ATIII) is a key antiproteinase involved in blood coagulation. Previous investigations have shown that ATIII is degraded by Staphylococcus aureus V8 protease, leading to release of heparin binding fragments derived from its D helix. As heparin binding and antimicrobial activity of peptides frequently overlap, we here set out to explore possible antibacterial effects of intact and degraded ATIII. In contrast to intact ATIII, the results showed that extensive degradation of the molecule yielded fragments with antimicrobial activity. Correspondingly, the heparin-binding, helix D-derived, peptide FFFAKLNCRL-YRKANKSSKLV (FFF21) of human ATIII, was found to be antimicrobial against particularly the Gram-negative bacteria Escherichia coli and Pseudomonas aeruginosa. Fluorescence microscopy and electron microscopy studies demonstrated that FFF21 binds to, and permeabilizes, bacterial membranes. Analogously, FFF21 was found to induce membrane leakage of model anionic liposomes. In vivo, FFF21 significantly reduced P. aeruginosa infection in mice. Additionally, FFF21 displayed anti-endotoxic effects in vitro. Taken together, our results suggest novel roles for ATIII-derived peptide fragments in host defense.Accepted versio

    Not AvailableThe objective of this study was to carry out the economic evaluation of different aquaculture systems in coastal waters of Goa. Break-even analysis was used to compute the economic viability of different culture systems. A survey was also conducted to study the perception of farmers on different aquaculture technologies introduced in coastal waters. Among the four aquaculture systems studied, the semi-enclosed multi-species culture system was the most productive. The highest benefit-cost ratio and rate of return and shortest payback period were observed for the semi-enclosed water system with multi-species culture. Thus, the multi-species culture was found more economically viable compared to the single-species system under similar environmental conditions. Moreover, for the semi-enclosed system, the productivity and survival of species were comparatively higher due to the control of water flow through sluice gates. Goa is rich in semi-enclosed water bodies, which have a history of being used for shrimp farming, but these systems can be utilized for multi-species aquaculture. Perception of farmers on the dissemination of culture techniques revealed that adequate technical support increases their confidence level. This paper posits that there is sufficient scope and feasibility for developing multi-species aquaculture practices inunutilised semi-enclosed coastal areas of Goa by giving adequate technical support to the farmers.Not Availabl
