Microbial assemblage in an n-alkanes-dependent thermophilic methanogenic enrichment cultures derived from production waters of a high-temperature petroleum reservoir was investigated in this study. Substantially higher amounts of methane were generated from the enrichment cultures incubated at 55 °C for 528 days with a mixture of long-chain n-alkanes(More)
Hepatocellular carcinoma (HCC) is one of the most malignant cancers and ranks as the third leading cause of cancer-related death in the world. However, some patients with untreated HCC can experience spontaneous regression, a rare phenomenon that has been observed in various malignancies. Here, we report a unique case with untreated HCC, who first underwent(More)
Systemic lupus erythematosus (SLE) is an autoimmune disease, with multiple genetic and environmental factors involving in its etiology. Angiotensin converting enzyme (ACE) gene was reported to have important roles in the development and progression of SLE. In this study, a case–control study was carried out to investigate the effects of seven SNPs and I/D(More)
This paper investigates how we can work towards building net-centric swarms of land, sea and air robots working together to accomplish a common goal. The goal is to bring together swarms of robots from all three sectors to safely benefit mankind without increasing dangers in the process. Several platforms are explored for simulation to investigate swarm(More)
Calcium (Ca2+)/calmodulin (CaM), a core component of calcium messenger system, is a multiple second messenger that is involved in multiple stress tolerance including heat tolerance in plants, hydrogen sulfide (H2S) is fast emerging similar functions, but Ca2+ and H2S crosstalk in the acquisition of thermotolerance is not completely understood. In this(More)
Anaerobic degradation of alkanes in hydrocarbon-rich environments has been documented and different degradation strategies proposed, of which the most encountered one is fumarate addition mechanism, generating alkylsuccinates as specific biomarkers. However, little is known about the mechanisms of anaerobic degradation of alkanes in oil reservoirs, due to(More)
Lipopeptides produced by microorganisms are one of the five major classes of biosurfactants known and they have received much attention from scientific and industrial communities due to their powerful interfacial and biological activities as well as environmentally friendly characteristics. Microbially produced lipopeptides are a series of chemical(More)
The methanogenic alkanes-degrading enrichment culture which had been incubated for over 1,300 days amended with n-alkanes (C15–C20) was investigated through clone libraries of bacteria, archaea and assA, mcrA functional genes. These enrichment cultures were obtained from oily sludge after an initial incubation of the oily sludge without any carbon source(More)
Hydrogen sulfide (H2S) is a multifunctional second messenger involved in plant growth, development, and acquisition of stress tolerance, including heat tolerance, but the mechanism of H2S-induced heat tolerance in tobacco suspension-cultured cells is not completely clear. This study investigated the effects of pretreatment with the H2S donor sodium(More)
This paper presents a novel compact dual-band and dual-polarized complementary split-ring resonator (CSRR)-fed substrate-integrated waveguide (SIW) cavity-backed fractal patch antenna for wireless energy harvesting and communication. The proposed antenna is composed of a Giuseppe Peano fractal radiation patch with a backed SIW cavity. To enhance the(More)
