A Case Report on Canine Transmissible Venereal Tumor
A male Japanese spitz (3 years) was brought at Himalayan Animal Rescue Trust (HART), Pokhara with a complaint of swollen gums and loss of appetite. A lobulated tumorous mass was seen at the gingival region on physical examination. Diagnosis and treatment of condition detected in the dog was the major objective. Impression smear of tumor cell was prepared and was observed under oil immersion microscope (100x). Microscopic examination shows the presence of vacuolations within the cytoplasm and the condition was diagnosed to be CTVT. Chemotherapy was performed using the most effective cytostatic agents I.e. Vincristine sulphate (once a week, I/v). The chemotherapy was repeated for 3 doses till the tumor gets completely regressed. The condition was resolved after third session of chemotherapy. Myelosuppression and gastrointestinal effects like vomiting are the major complications of using vincristine
Organoleptic and grain quality traits of aromatic rice varieties as influenced by supplementation of Zn and 2-acetyl-1-pyrroline
Aromatic rice fetches premium prices in world markets due to its pleasant smell and enchanting flavor. In Bangladesh, the quality of aromatic rice is much inferior than those of other rice growing countries because of lack of improved variety and judicious agronomic management. Selection of appropriate variety and supplementation zinc (Zn) and 2-acetyl-1-pyrroline (2-AP) can improve the aroma. The present study exhibited the effects of 2-AP and Zn supplementation on yield and quality of aromatic rice. Two well-known aromatic cultivars, BRRI dhan80 and BRRI dhan34, were cultured separately in pot supplemented with 2-AP and Zn. The results showed that supplementation of 2-AP and /or Zn along with conventional practices had significant effects on organoleptic and some quality parameters studied in this study. The concentration of 2AP and Zn in rice grain increased with increasing their application rate. Additionally, grain 2-AP concentrations were significantly and positively correlated with organoleptic characters. Interactions of both these elements with the complex process of 2-AP formation remain to be explored
Large expert-curated database for benchmarking document similarity detection in biomedical literature search
Document recommendation systems for locating relevant literature have mostly relied on methods developed a decade ago. This is largely due to the lack of a large offline gold-standard benchmark of relevant documents that cover a variety of research fields such that newly developed literature search techniques can be compared, improved and translated into practice. To overcome this bottleneck, we have established the RElevant LIterature SearcH consortium consisting of more than 1500 scientists from 84 countries, who have collectively annotated the relevance of over 180 000 PubMed-listed articles with regard to their respective seed (input) article/s. The majority of annotations were contributed by highly experienced, original authors of the seed articles. The collected data cover 76% of all unique PubMed Medical Subject Headings descriptors. No systematic biases were observed across different experience levels, research fields or time spent on annotations. More importantly, annotations of the same document pairs contributed by different scientists were highly concordant. We further show that the three representative baseline methods used to generate recommended articles for evaluation (Okapi Best Matching 25, Term Frequency-Inverse Document Frequency and PubMed Related Articles) had similar overall performances. Additionally, we found that these methods each tend to produce distinct collections of recommended articles, suggesting that a hybrid method may be required to completely capture all relevant articles. The established database server located at https://relishdb.ict.griffith.edu.au is freely available for the downloading of annotation data and the blind testing of new methods. We expect that this benchmark will be useful for stimulating the development of new powerful techniques for title and title/abstract-based search engines for relevant articles in biomedical research.Peer reviewe
Factors associated with chronic obstructive pulmonary diseases in Nepal: evidence from a nationally representative population-based study
Background: The Global Burden of Diseases Study 2017 predicted that chronic obstructive pulmonary disease (COPD) is the second leading cause of death, the fourth leading cause of premature death, and the third cause for DALYs lost in Nepal. However, data on the population-based prevalence of COPD in Nepal are very limited. This study aims to assess the prevalence of COPD and factors associated with the occurrence of COPD in Nepal.
Methods: From a nationally representative, population-based cross-sectional study on chronic non-communicable diseases, the prevalence of COPD and its associated factors was determined. Of 12,557 participants aged over 20 years, 8945 participants completed a questionnaire and spirometry. Eligible participants were also asked to answer a COPD diagnostic questionnaire for screening COPD cases, and if needed underwent pre-bronchodilator and post-bronchodilator spirometry. COPD was defined as a post-bronchodilator FEV1/FVC (forced expiratory volume in 1 s/forced vital capacity) ratio of < 0.70. Multivariate logistic regression was performed to identify factors associated with COPD. Sampling weights were used for all data analyses.
Results: The prevalence of COPD in Nepal was 11.7% (95% CI: 10.5% to 12.9 %), which increased with age, and higher in those with a low educational level, those who had smoked â„ 50 pack-years, persons having a low body mass index (BMI), and residents of Karnali province. Multivariate analysis revealed that being aged 60 years and above, having a low BMI, low educational status, having smoked more than 50 pack-years, provincial distribution, and ethnicity were independent predictors of COPD.
Conclusion: COPD is a growing and serious public health issue in Nepal. Factor such as old age, cigarette smoking, low educational attainment, low BMI, ethnicity, and locality of residence (province-level variation) plays a vital role in the occurrence of COPD. Strategies aimed at targeting these risk factors through health promotion and education interventions are needed to decrease the burden of COPD

Gauging the effects of the COVID-19 pandemic lockdowns on atmospheric pollution content in select countries

Not AvailableMango (Mangifera indica L.) is known as the âking of fruitsâ for its rich taste, flavor, color,
production volume and diverse end usage. It belongs to plant family Anacardiaceae and has a small
genome size of 439 Mb (2n = 40). Ancient literature indicates origin of cultivated mango in India. Although
wild species of genus Mangifera are distributed throughout South and South-East Asia, recovery of
Paleocene mango leaf fossils near Damalgiri, West Garo Hills, Meghalaya point to the origin of genus in
peninsular India before joining of the Indian and Asian continental plates. India produces more than fifty
percent of the worldâs mango and grows more than thousand varieties. Despite its huge economic
significance genomic resources for mango are limited and genetics of useful horticultural traits are poorly
understood. Here we present a brief account of our recent efforts to generate genomic resources for
mango and its use in the analysis of genetic diversity and population structure of mango cultivars.
Sequencing of leaf RNA from mango cultivars âNeelamâ, âDashehariâ and their hybrid âAmrapaliâ revealed
substantially higher level of heterozygosity in âAmrapaliâ over its parents and helped develop genic
simple sequence repeat (SSR) and single nucleotide polymorphism (SNP) markers. Sequencing of double
digested restriction-site-associated genomic DNA (ddRAD) of 84 diverse mango cultivars identified
1.67 million high quality SNPs and two major sub-populations. We have assembled 323 Mb of the highly
heterozygous âAmrapaliâ genome using long sequence reads of PacBio single molecule real time (SMRT)
sequencing chemistry and predicted 43,247 protein coding genes. We identified in the mango genome
122,332 SSR loci and developed 8,451 Type1 SSR and 835 HSSR markers for high level of polymorphism.
Among the published genomes, mango showed highest similarity with sweet orange (Citrus sinensis).
