Ignitability Study of a Spark-ignited Heavy-duty Engine, fueled with Natural Gas (CNG)

In-order to meet today’s stringent emission regulations of the European Union, the use of low-carbon fuels in ICE, for instance, Natural Gas (CNG)1 is on the limelight. Due to the high knock-resisting properties of methane (high octane rating), the SI (Spark-Ignition) combustion process is the best match with CNG1. A major disadvantage with an SI engine is its low thermal efficiency mainly due to

Using BIM Data Together with City Models : Exploring the Opportunities and Challenges

An increasing number of cities are creating 3D city models to support visualization and simulations in the urban planning process. The 3D city models are often extended with planned buildings. One way to facilitate this is to add simplified building information modelling (BIM) models of the planned buildings to the 3D city model. This article summarizes some of the recent academic and industrial s

FILTRATION QUALITY: A NEW MEASURE OF RENAL DISEASE

Background Although GFR is a good general indicator of renal disease, it will not detect those renal diseases in which the composition of the glomerular filtrate is deranged in the presence of a normal GFR. Markers for filtration quality were therefore sought.Methods The plasma levels of GFR-markers of various sizes were determined in healthy pregnant females, in patients with preeclampsia or on h

A comparison of cost-effectiveness of computer-assisted 2-and 3-dimensional planning techniques in orthognathic surgery

The aim of this randomised controlled trial was to compare the costs and benefits of computer-based 2-dimensional and 3-dimensional predictions in orthognathic surgery.Subjects aged 18–30 years with severe class III malocclusion had their treatment planned with both 2- and 3-dimensional techniques. They were randomised in a 1:1 ratio for one or other planning technique. Costs (financial, time, and

The aim of this report is to provide a detailed description of the eight development projects recommended for the first strategy period (2021-2023) of the project “A National Strategy for Standardisation of Digital Information Management within the Built Environment”. The report also contains a description of the vision and the objectives of the strategy. The project has been led by Pontus Bengtso

Association of tobacco smoke–infused water (tuibur) use by Mizo people and risk of Helicobacter pylori infection

The study aims to understand the influence of environmental and lifestyle factors and more specifically the role of tobacco smoke–infused water (tuibur) on Helicobacter pylori infection. It was a cross-sectional study to measure the epidemiological risk factors associated with H. pylori infection among the tribal population in Northeast India. Endoscopic samples were collected from the antrum regi

Induction of Apoptosis by Pierisin-6 in HPV Positive HeLa and HepG2 Cancer Cells is Mediated by the Caspase-3 Dependent Mitochondrial Pathway

BackgroundTo explore the cytotoxic and apoptotic activity of the pierisin-6 protein in HPV HeLa and HepG2 cell lines.MethodsIn this study, isolation, and purification of cytotoxic Prierisin-6 from the larvae of Pieris napi by affinity column chromatography techniques. Characterization of full-length mRNA of pierisin-6 gene was performed using 3'/5' RACE PCR. The quantitative RT-PCR used to study t

Lifestyle chemical carcinogens associated with mutations in cell cycle regulatory genes increases the susceptibility to gastric cancer risk

In the present study, we correlated the various lifestyle habits and their associated mutations in cell cycle (P21 and MDM2) and DNA damage repair (MLH1) genes to investigate their role in gastric cancer (GC). Multifactor dimensionality reduction (MDR) analysis revealed the two-factor model of oral snuff and smoked meat as the significant model for GC risk. The interaction analysis between identif

Influence of TP53 gene somatic mutations in Helicobacter pylori infected gastric tumor

Genetic alteration in TP53 gene can proliferate the tumor formation in gastric cancer and the frequency of these somatic mutations can vary in different geographical populations. In the present study, sequencing of the coding regions of TP53 gene, real time gene expression and immunohistochemistry analysis were performed in gastric tumor samples. H. pylori infected tumor, with or without cagA geno

Novel AKT1 mutations associated with cell-cycle abnormalities in gastric carcinoma

Aim: The aim of this study is to identify the AKT1 gene mutation driven pathogenicity in gastric cancer for Mizo population. Methods: 50 diffuse-type gastric tumors were analyzed for AKT1 exon 2 and 14 mutations. Cell-cycle aberration was analyzed in the AKT1-mutated samples and the stability of the protein as well as exonic splicing enhancer motifs were examined. Results: The novel mutations, 155

Safe and Robust Autonomous Intersection Management Methods

Connected Autonomous Vehicles (AV)s can transform urban transportation systems and have the potential to improve the safety and efficiency, since human errors and distractions are removed. However, these systems are vulnerable to model uncertainties, communication impairments associated with the wireless communication, and external disturbances. As a result, vehicles need to drive at low speed and

Mitochondrial complex I and V gene polymorphisms in type II diabetes mellitus among high risk Mizo-Mongoloid population, Northeast India

IntroductionThe study was carried out to identify the polymorphisms in mitochondrial genes (ATPase and ND1) in type 2 Diabetes Mellitus (T2DM) from Mizo population and to correlate the involvement of demographic factors.FindingsIn the present study, 58 patients and 50 healthy volunteers were considered. The mutations observed were mostly base substitutions and were similar as reported for other po

Relevance of GSTM1, GSTT1 and GSTP1 Gene Polymorphism to Breast Cancer Susceptibility in Mizoram Population, Northeast India

The enzymes encoded by glutathione S-transferase mu 1 (GSTM1) and theta 1 (GSTT1) genes are involved in the metabolism of wide range of carcinogens that are ubiquitous in the environment. Homozygous deletions of the GSTM1 and GSTT1 genes are commonly found and result in lack of enzyme activity. This study was undertaken to evaluate the association between GSTM1, GSTT1 and GSTP1 gene polymorphism a

Synthesis of silver and gold nanoparticles using Jasminum nervosum leaf extract and its larvicidal activity against filarial and arboviral vector Culex quinquefasciatus Say (Diptera: Culicidae)

Silver and gold nanoparticles of Jasminum nervosum L. had unique optical properties such as broad absorbance band in the visible region of the electromagnetic spectrum. Characterization of the nanoparticles using UV spectrophotometer, Fourier transform infrared spectroscopy, X-ray diffraction, and transmission electron microscopy confirmed that the particles were silver (AgNPs) and gold (AuNPs) ra

Coextraction and PCR Based Analysis of Nucleic Acids From Formalin-Fixed Paraffin-Embedded Specimens

BackgroundRetrospective studies of archived human specimens, with known clinical follow-up, are used to identify predictive and prognostic molecular markers of disease. Due to biochemical differences, however, formalin-fixed paraffin embedded (FFPE) DNA and RNA have generally been extracted separately from either different tissue sections or from the same section by dividing the digested tissue. O

A Simple Method of Genomic DNA Extraction from Human Samples for PCR-RFLP Analysis

Isolation of DNA from blood and buccal swabs in adequate quantities is an integral part of forensic research and analysis. The present study was performed to determine the quality and the quantity of DNA extracted from four commonly available samples and to estimate the time duration of the ensuing PCR amplification. Here, we demonstrate that hair and urine samples can also become an alternate sou
