Orthotopic Liver Transplantation in a Case of Novel YAP1-TFE3 Hepatic Epithelioid Hemangioendothelioma [HEHE]; Case Report and Review of Literature
Epithelioid hemangioendothelioma is an extremely rare vascular neoplasm arising in soft-tissues and different visceral organs, with liver being the most commonly involved viscera. Hepatic epithelioid hemangioendothelioma (HEHE) is a malignant tumour with an indolent behaviour and unpredictable clinical course. It has a better prognosis among the malignant tumours of the liver, in spite of being a diffuse multifocal liver disease or metastatic at the time of presentation. HEHE is usually found to be noted in the fifth decade with slight female preponderance. No single treatment strategy has yet been established owing to its variable clinical course, ranging from an indolent tumour with prolonged survival to an aggressive, metastatic disease with a fatal outcome. Here, we present a case of a novel HEHE in a 25-year-old female who was treated successfully with orthotopic living donor liver transplantation and discuss the presentation, histopathology and management of this rare, fatal yet treatable malignant tumour
Minichromosome Maintenance Complex (MCM) Genes Profiling and MCM2 Protein Expression in Cervical Cancer Development
Objective: Minichromosome maintenance complex (MCM) proteins are essential for the process of DNA replication
and cell division. This study aimed to evaluate MCM genes expression profiles and MCM2 protein in HPV-associated
cervical carcinogenesis. Methodology: MCM2, 4, 5 and 7 genes expression profiles were evaluated in three cervical
tissue samples each of normal cervix, human papillomavirus (HPV)-infected low grade squamous intraepithelial
lesion (LSIL), high grade squamous intraepithelial lesion (HSIL) and squamous cell carcinoma (SCC), using Human
Transcriptome Array 2.0 and validated by nCounterĀ® PanCancer Pathway NanoString Array. Immunohistochemical
expression of MCM2 protein was semi-quantitatively assessed by histoscore in tissue microarrays containing 9 cases of
normal cervix, 10 LSIL, 10 HSIL and 42 cases of SCC. Results: MCM2, 4, 5 and 7 genes expressions were upregulated
with increasing fold change during the progression from LSIL to HSIL and the highest in SCC. MCM2 gene had the
highest fold change in SCC compared to normal cervix. Immunohistochemically, MCM2 protein was localised in
the nuclei of basal cells of normal cervical epithelium and dysplastic-neoplastic cells of CIN and SCC. There was a
significant difference in MCM2 protein expression between the histological groups (P = 0.039), and histoscore was the
highest in HSIL compared to normal cervix (P = 0.010). Conclusion: The upregulation of MCM genes expressions in
cervical carcinogenesis reaffirms MCM as a proliferative marker in DNA replication pathway, whereby proliferation of
dysplastic and cancer cells become increasingly dysregulated and uncontrolled. A strong expression of MCM2 protein
in HSIL may aid as a concatenated screening tool in detecting pre-cancerous cervical lesions
Avenues in supercritical carbon dioxide extraction and fractionation of lipids.
Supercritical carbon dioxide (scCO2) offers an alternative ecofriendly method for the conventional solvent extraction of lipids. CO2-based fluids are ideal supercritical fluids thanks to their distinct characteristics, such as nonflammability, nontoxicity, abundance, and recyclability, as well as their ability to solubilize lipophilic substances. Many studies have been conducted on the lipids extraction and fractionation from various lipid sources using scCO2 with or without a co-solvent. These studies revealed that scCO2 is a predominant technology for the lipids extraction and fractionation from various lipid sources. The present review was conducted to determine the influence of scCO2 process parameters on the extraction and fractionation of lipids from various plant and animal sources. Further, the influences of various operating parameters for the lipid extraction and fractionation subjected scCO2 extraction technology were also reviewed
Treatment of Clinical Solid Waste Using a Steam Autoclave as a Possible Alternative Technology to Incineration
A steam autoclave was used to sterilize bacteria in clinical solid waste in order to determine an alternative to incineration technology in clinical solid waste management. The influence of contact time (0, 5, 15, 30 and 60 min) and temperature (111 Ā°C, 121 Ā°C and 131 Ā°C) at automated saturated steam pressure was investigated. Results showed that with increasing contact time and temperature, the number of surviving bacteria decreased. The optimum experimental conditions as measured by degree of inactivation of bacteria were 121 Ā°C for 15 minutes (min) for Gram negative bacteria, 121 Ā°C and 131 Ā°C for 60 and 30 min for Gram positive bacteria, respectively. The re-growth of bacteria in sterilized waste was also evaluated in the present study. It was found that bacterial re-growth started two days after the inactivation. The present study recommends that the steam autoclave cannot be considered as an alternative technology to incineration in clinical solid waste management
Machine-Part cell formation through visual decipherable clustering of Self Organizing Map
Machine-part cell formation is used in cellular manufacturing in order to
process a large variety, quality, lower work in process levels, reducing
manufacturing lead-time and customer response time while retaining flexibility
for new products. This paper presents a new and novel approach for obtaining
machine cells and part families. In the cellular manufacturing the fundamental
problem is the formation of part families and machine cells. The present paper
deals with the Self Organising Map (SOM) method an unsupervised learning
algorithm in Artificial Intelligence, and has been used as a visually
decipherable clustering tool of machine-part cell formation. The objective of
the paper is to cluster the binary machine-part matrix through visually
decipherable cluster of SOM color-coding and labelling via the SOM map nodes in
such a way that the part families are processed in that machine cells. The
Umatrix, component plane, principal component projection, scatter plot and
histogram of SOM have been reported in the present work for the successful
visualization of the machine-part cell formation. Computational result with the
proposed algorithm on a set of group technology problems available in the
literature is also presented. The proposed SOM approach produced solutions with
a grouping efficacy that is at least as good as any results earlier reported in
the literature and improved the grouping efficacy for 70% of the problems and
found immensely useful to both industry practitioners and researchers.Comment: 18 pages,3 table, 4 figure
Air pollution from household solid fuel combustion in India: an overview of exposure and health related information to inform health research priorities
Environmental and occupational risk factors contribute to nearly 40% of the national burden of disease in India, with air pollution in the indoor and outdoor environment ranking amongst leading risk factors. It is now recognized that the health burden from air pollution exposures that primarily occur in the rural indoors, from pollutants released during the incomplete combustion of solid fuels in households, may rival or even exceed the burden attributable to urban outdoor exposures. Few environmental epidemiological efforts have been devoted to this setting, however. We provide an overview of important available information on exposures and health effects related to household solid fuel use in India, with a view to inform health research priorities for household air pollution and facilitate being able to address air pollution within an integrated ruralāurban framework in the future
Human Protein Reference Databaseā2009 update
Human Protein Reference Database (HPRDāhttp://www.hprd.org/), initially described in 2003, is a database of curated proteomic information pertaining to human proteins. We have recently added a number of new features in HPRD. These include PhosphoMotif Finder, which allows users to find the presence of over 320 experimentally verified phosphorylation motifs in proteins of interest. Another new feature is a protein distributed annotation systemāHuman Proteinpedia (http://www.humanproteinpedia.org/)āthrough which laboratories can submit their data, which is mapped onto protein entries in HPRD. Over 75 laboratories involved in proteomics research have already participated in this effort by submitting data for over 15 000 human proteins. The submitted data includes mass spectrometry and protein microarray-derived data, among other data types. Finally, HPRD is also linked to a compendium of human signaling pathways developed by our group, NetPath (http://www.netpath.org/), which currently contains annotations for several cancer and immune signaling pathways. Since the last update, more than 5500 new protein sequences have been added, making HPRD a comprehensive resource for studying the human proteome
