#1
Sayka Jahan, Vladimir Strezov
Australian ports serve diverse and extensive activities, such as shipping, tourism and fisheries, which may all impact the quality of port water. In this work water quality monitoring at different ports using a range of water quality evaluation indices was applied to assess the port water quality. Seawater samples at 30 stations in the year 2016-2017 from six ports in NSW, Australia, namely Port Jackson, Botany, Kembla, Newcastle, Yamba and Eden, were investigated to determine the physicochemical and biological variables that affect the port water quality...

<p>Reconstruction of defects of the lower lip can be very challenging. The aim of this review is to analyze the unique characteristics of lower lip anatomy and provide a systematic approach for lower lip reconstruction. A review of current literature was performed using the PubMed database. Articles analyzing the anatomic and histologic characteristics of the lower lip, mechanics of local faps, and different lower lip recon-struction techniques were included. Articles focused on lower lip reconstruction with free faps were excluded...

David R Bayliss, Jed Duff, Philip Stricker, Kim Walker
A literature review was done using the Cognitive-Social Health Information Processing (C-SHIP) framework to identify how and why men diagnosed with prostate cancer choose active surveillance over other treatment options. Findings indicated men who choose active surveillance have a stronger preference for active or collaborative decision-making than those who choose other treatments. Men primarily choose active surveillance to avoid the side effects of incontinence and erectile dysfunction. This literature review informed the study by Bayliss, Duff, Strieker, and Walker (2016) and found physician recommendation to be the most influential factor when patients make a treatment decision...

BACKGROUND AND AIMS: A potential causal relationship between thyroid function and type 2 diabetes mellitus is currently under debate, but the current state of research is limited. Our aim was to investigate the association of thyroid hormone levels with prevalent and incident type 2 diabetes mellitus (T2DM) in two representative studies. METHODS AND RESULTS: Analyses are based on data from the Study of Health in Pomerania (SHIP), a German population based cohort with 4308 individuals at baseline and 3300 individuals at a five-year follow-up, and from INTER99, a Danish population-based randomized controlled trial with 6784 individuals at baseline and 4516 individuals at the five-year-follow-up...

Frank Simione, Tim Sharp
Successfully recovering stored cryopreserved cells requires attention to two major factors, i.e., storage temperature and proper handling of the frozen samples. These key considerations are in turn impacted by how the inventory system is constructed, the frequency and process for retrieving specimens, as well as how the material is secured. In addition, shipping biological materials requires attention to the type of material transported, adherence to regulatory requirements, packaging materials and proper assembly, labeling, and engaging reputable carriers...

Ji-Soo Park, Jeung-Hoon Lee
An ultrasonic antifouling treatment was applied to a 96,000 m3 class drill-ship to verify its feasibility through a sea-trial. Soon after the hull cleaning had been performed, six ultrasonic projectors were evenly deployed around the starboard shell plate. Driven by a 23 kHz sinusoidal ultrasound in an intermittent manner, the projectors emitted a high-intensity sound reaching 214 dB at the source level causing cavitation around the adjacent water and eventually deterring the settlement of marine fouling organisms...

Persistent organic pollutants (POPs) have been a topic of interest in environmental sciences for >60years. POPs in the Arctic have been investigated since the 1970s, when first atmospheric measurements revealed the presence of these pollutants in the polar regions. Major contaminant transport routes to the Arctic include atmospheric and oceanic transport, as well as inflow from rivers and sea ice. The sources of pollutants, such as industry, power generators, vehicle and ship exhausts, introduce the PAHs, phenols, formaldehyde or metals into the Arctic...

The WHO Surgical Safety Checklist was launched in 2009, and appropriate use reduces mortality, surgical site infections and complications after surgery by up to 50%. Implementation across low-income and middle-income countries has been slow; published evidence is restricted to reports from a few single institutions, and significant challenges to successful implementation have been identified and presented. The Mercy Ships Medical Capacity Building team developed a multidisciplinary 3-day Surgical Safety Checklist training programme designed for rapid wide-scale implementation in all regional referral hospitals in Madagascar...

It is highly difficult to perform safe surgery without sterile instruments, yet the capacity to adequately clean, disinfect and sterilise surgical instruments in low-income and middle-income countries is largely unknown. Sterile Processing Education Charitable Trust developed an assessment tool and, in partnership with Mercy Ships, evaluated the sterile processing capacity in 59 facilities in Madagascar, Benin and the Republic of Congo. This data-driven analysis paper illustrates how lack of sterile processing capacity acts as a barrier to safe surgical care...

Activation of trace amine-associated receptor 1 (TAAR1) in endocrine pancreas is involved in weight regulation and glucose homeostasis. The purpose of this study was the identification and characterization of potential TAAR1 variants in patients with overweight/obesity and disturbed glucose homeostasis. Screening for TAAR1 variants was performed in 314 obese or overweight patients with impaired insulin secretion. The detected variants were functionally characterized concerning TAAR1 cell surface expression and signaling properties and their allele frequencies were determined in the population-based Study of Health in Pomerania (SHIP)...

The National Survey of Disinfection By-Products and Selected Emerging Contaminants investigated the formation of various disinfection by-products and contaminants in 65 water treatment systems (WTSs) across Canada. Results for six iodo-trihalomethanes (iodo-THMs) are reported in this paper. The participating water treatment systems included large, medium and small systems using water sources and treatment processes which were representative of Canadian drinking water. Five water samples (source water, treated water and three water samples along the distribution system) were collected from each treatment system, both under winter and summer conditions...

Research into human performance on naval ships often emphasizes the significance of shaping factors, such as vigilance, fatigue and circadian rhythm. However, few report on the presence of complex nonlinear dynamics and fractal dimensionality. This study examines over 7000 routine topside security checks on a U.S. Navy Destroyer performed over a twelve-month period. Time series analysis (0-1 test, analysis of Lyapunov exponent, state space plots, and graphical analysis) reveal the presence of chaotic behavior, harmonics attractors, and fractal structures...

Riverine debris in the Three Gorges Reservoir Area (TGRA) poses a threat to electricity generation, ship navigation, and water environment. Quantifying riverine debris inputs from land into the river is a foundation for modeling of the transport and accumulation of floating debris on the water surface in the TGRA. However, this has not been researched to date. In this study, debris inputs from land into the river in the TGRA were assessed according to the response relationship between debris inputs and surface runoff...

Serum neuron-specific enolase (sNSE) is considered a marker for neuronal damage, related to gray matter structures. Previous studies indicated its potential as marker for structural and functional damage in conditions with adverse effects to the brain like obesity and dementia. In the present study, we investigated the putative association between sNSE levels, body mass index (BMI), total gray matter volume (GMV), and magnetic resonance imaging-based indices of aging as well as Alzheimer's disease (AD)-like patterns...

In this study, the NOx emission factor and total NOx emissions of two groups of post-Panamax container ships operating on a long-term slow steaming basis along Euro-Asian routes were calculated using both the probability density function of engine power levels and the NOx emission function. The main engines of the five sister ships in Group I satisfied the Tier I emission limit stipulated in MARPOL Annex VI, and those in Group II satisfied the Tier II limit. The calculated NOx emission factors of the Group I and Group II ships were 14...

Testing of peripheral blood mononuclear cells (PBMC) for immune monitoring purposes requires verification of their functionality. This is of particular concern when the PBMC have been shipped or stored for prolonged periods of time. While the CEF (Cytomegalo-, Epstein-Barr and Flu-virus) peptide pool has become the gold standard for testing CD8 cell functionality, a positive control for CD4 cells is so far lacking. The latter ideally consists of proteins so as to control for the functionality of the antigen processing and presentation compartments, as well...

Complement receptor 3 (CR3) is expressed abundantly on natural killer (NK) cells; however, whether it plays roles in NK cell-dependent tumor surveillance is largely unknown. Here, we show that CR3 is an important negative regulator of NK cell function, which has negative impact on tumor surveillance. Mice deficient in CR3 (CD11b-/- mice) exhibited a more activated NK phenotype and had enhanced NK-dependent tumor killing. In a B16-luc melanoma-induced lung tumor growth and metastasis model, mice deficient in CR3 had reduced tumor growth and metastases, compared with WT mice...
