Screening of alginate lyase-excreting microorganisms from the surface of brown algae

Alginate lyase is a biocatalyst that degrades alginate to produce oligosaccharides, which have many bioactive functions and could be used as renewable biofuels. Here we report a simple and sensitive plate assay for screening alginate lyase-excreting microorganisms from brown algae. Brown algae Laminaria ...

Two new species of Leptopsyllus from Korea ( Copepoda, Harpacticoida, Paramesochridae)

Abstract Two new species of Leptopsyllus are described from the subtidal zone of Korea. Both species were assigned to the subgenus Leptopsyllus ( Leptopsyllus) T. Scott, 1894, based on following three characters: two-segmented rami of P1, absence of endopod on P2 and P3, and presence of one-segmented ...

Thermal stratification drives movement of a coastal apex predator

A characterization of the thermal ecology of fishes is needed to better understand changes in ecosystems and species distributions arising from global warming. The movement of wild animals during changing environmental conditions provides essential information to help predict the future thermal response ...

Multiple gene variations contributed to congenital heart disease via GATA family transcriptional regulation

Background Congenital heart disease (CHD) is a common birth defect, and most cases occur sporadically. Mutations in key genes that are responsible for cardiac development could contribute to CHD. To date, the genetic causes of CHD remain largely unknown. Methods In this study, twenty-nine candidate ...

Eukaryotic Life Inhabits Rhodolith-forming Coralline Algae (Hapalidiales, Rhodophyta), Remarkable Marine Benthic Microhabitats

Rhodoliths are benthic calcium carbonate nodules accreted by crustose coralline red algae which recently have been identified as useful indicators of biomineral changes resulting from global climate change and ocean acidification. This study highlights the discovery that the interior of rhodoliths are ...

Proteomic signature of muscle fibre hyperplasia in response to faba bean intake in grass carp

Fish muscle growth is important for the rapidly developing global aquaculture industry, particularly with respect to production and quality. Changes in muscle fibre size are accomplished by altering the balance between protein synthesis and proteolysis. However, our understanding regarding the effects ...

Actual measurement, hygrothermal response experiment and growth prediction analysis of microbial contamination of central air conditioning system in Dalian, China

The microbial contamination of central air conditioning system is one of the important factors that affect the indoor air quality. Actual measurement and analysis were carried out on microbial contamination in central air conditioning system at a venue in Dalian, China. Illumina miseq method was used ...

Biodiversity and Ecosystem Services Risk Assessment BESRA for 2D Land Seismic Survey: Case Study of Open Block SK6-00 Limbang, Sarawak

Abstract The process to conduct a Biodiversity and Ecosystem Services Risk Assessment (BESRA) was established to enhance situational baseline on biodiversity data for PETRONAS’ upstream and downstream operations, and reducing the impacts on biodiversity in areas of its operation. The location for this ...

Cooperative Vehicle Automation: Safety Aspects and Control Software Architecture

Automated vehicles are designed to take over all or part of the driver's task, in order to safely and comfortably navigate through road traffic. Automated vehicles, however, are limited by the line-ofsight characteristics of the on-board sensors, e.g., radar, lidar, and camera. To overcome this limitation, ...

Design of small autonomous boat for course-keeping manuevers

This paper presents design, modeling and control of a small autonomous boat (SAB) where an Remote Control (RC) commercial boat is augmented with an embedded system and the required sensors in order to conduct simple maneuvers autonomously. The detailed kinematic and dynamic equations of the SAB are ...

Condition monitoring of industrial infrastructures using distributed fibre optic acoustic sensors

Distributed fibre optic acoustic sensing (DAS) can serve as an excellent tool for real-time condition monitoring of a variety of industrial and civil infrastructures. In this paper, we portray a subset of our current research activities investigating the usability of DAS based on coherent optical time-domain ...

Towards efficient real-time submarine power cable monitoring using distributed fibre optic acoustic sensors

Online condition monitoring of submarine power cables helps to avert failures and damages produced by mechanical impacts. We report, to our knowledge for the first time, on investigations regarding the feasibility of distributed fiber optic acoustic sensors based on C-OTDR, with the sensor fibres being ...

Augmented Terrain-Based Navigation to Enable Persistent Autonomy for Underwater Vehicles

To effectively examine ocean processes, sampling campaigns require persistent autonomous underwater vehicles that are able to spend a majority of their deployment time maneuvering and gathering data underwater. Current navigation techniques rely either on high-powered sensors (e.g. Doppler Velocity ...

Requirements for Reducing Underwater Noise From Ships

Awareness of underwater noise from shipping has grown significantly within the marine community over the past decade. Concerns have been raised about the levels of anthropogenic noise in the world's oceans, as well as in harbors and areas with sensitive or protected marine life. Regulatory bodies are ...

Nonylphenol in Human Breast Milk in Relation to Sociodemographic Variables, Diet, Obstetrics Histories and Lifestyle Habits in a Turkish Population

Background: Human breast milk is the most important food for infants and one of the main roads to exposure to toxic substances. In this study, nonylphenol (NP) levels in human milk samples collected from Turkish mothers (n=100) were determined, and the factors including mothers’ demographics, eating ...

The evolution of the major histocompatibility complex in upstream versus downstream river populations of the longnose dace

Abstract Populations in upstream versus downstream river locations can be exposed to vastly different environmental and ecological conditions and can thus harbor different genetic resources due to selection and neutral processes. An interesting question is how upstream–downstream directionality in ...

Implications of guppy (Poecilia reticulata) life‐history phenotype for mosquito control

Abstract Guppies (Poecilia reticulata) are frequently introduced to both natural and artificial water bodies as a mosquito control. Laboratory studies have demonstrated that guppies can consume large numbers of larval mosquitoes. Our study investigates how intraspecific variability in guppy phenotype ...

Effect of dietary supplementation of fermented fish silage on serum biochemical parameters of broiler Japanese quails (Coturnix coturnix japonica)

Aim: The objective of this study was to evaluate the effect of feeding fermented fish silage (FFS) on serum biochemical parameters of Japanese quails (Coturnix coturnix japonica). Materials and Methods: A total of 192, 7-day-old broiler Japanese quail chicks of either sex, were randomly distributed ...

The Effect of Interactions of Single Nucleotide Polymorphisms of APOA1/APOC3 with Food Group Intakes on the Risk of Metabolic Syndrome

Background: The aim of this study was to examine the interaction of dietary food groups and genetic variants of APOA1/APOC3, relative to Metabolic Syndrome (MetS) risk in adults. Methods: In this matched nested case-control study, 414 MetS subjects and 414 controls were selected from among participants ...

Development of Flow Cytometry-Fluorescent In Situ Hybridization (Flow-FISH) Method for Detection of PML/RARa Chromosomal Translocation in Acute Promyelocytic Leukemia Cell ...

Background: Acute Promyelocytic Leukemia (APL) is a subclass of acute myeloid leukemia. The chromosomal aberration in 95% of APL cases is t(15; 17) (q22; q21), which prevents cell differentiation. Characterization of the underlying molecular lesion is valuable in determining optimal treatment strategy. ...
