Advancing projections of crown-of-thorns starfish to support management interventions.

Outbreaks of corallivorous Crown of Thorns Starfish (Acanthaster spp.; CoTS) cause substantial coral mortality throughout the Indo-Pacific, particularly on the Great Barrier Reef (GBR). Refining CoTS population density modelling and understanding the disparities between real-world observations and model predictions is crucial for developing effective control strategies.

Real-time 3D tracking of swimming microbes using digital holographic microscopy and deep learning.

The three-dimensional swimming tracks of motile microorganisms can be used to identify their species, which holds promise for the rapid identification of bacterial pathogens. The tracks also provide detailed information on the cells' responses to external stimuli such as chemical gradients and physical objects. Digital holographic microscopy (DHM) is a well-established, but computationally intensive method for obtaining three-dimensional cell tracks from video microscopy data.

Protecting Great Barrier Reef resilience through effective management of crown-of-thorns starfish outbreaks.

Resilience-based management is essential to protect ecosystems in the Anthropocene. Unlike large-scale climate threats to Great Barrier Reef (GBR) corals, outbreaks of coral-eating crown-of-thorns starfish (COTS; Acanthaster cf. solaris) can be directly managed through targeted culling.

The effects of marine heatwaves on acute heat tolerance in corals.

Scleractinian coral populations are increasingly exposed to conditions above their upper thermal limits due to marine heatwaves, contributing to global declines of coral reef ecosystem health. However, historic mass bleaching events indicate there is considerable inter- and intra-specific variation in thermal tolerance whereby species, individual coral colonies and populations show differential susceptibility to exposure to elevated temperatures. Despite this, we lack a clear understanding of how heat tolerance varies across large contemporary and historical environmental gradients, or the selective pressures that underpin this variation.

An island of sanity during COVID-19 pandemic: Does pet attachment support buffer employees' stress due to job insecurity?

Drawing on the transactional theory of stress, the current study investigates whether employee job insecurity triggers employee behavioral strain reactions (i.e., alcohol use, marijuana use, and cigarette use) and psychological strain reactions (i.

Knowledge Gaps in the Biology, Ecology, and Management of the Pacific Crown-of-Thorns Sea Star sp. on Australia's Great Barrier Reef.

AbstractCrown-of-thorns sea stars ( sp.) are among the most studied coral reef organisms, owing to their propensity to undergo major population irruptions, which contribute to significant coral loss and reef degradation throughout the Indo-Pacific. However, there are still important knowledge gaps pertaining to the biology, ecology, and management of sp.

How to repair a small umbilical hernia laparoscopically.

We describe a step by step technique for repair of a small umbilical hernia laparoscopically that aims to provide an excellent technical and cosmetic result without a significant increase in operative time or cost. Patients report good quality of life post-operatively and appear satisfied with the cosmetic result.

Biogeographical variation in diurnal behaviour of Acanthaster planci versus Acanthaster cf. solaris.

Crown-of-thorns starfish (CoTS; Acanthaster spp.) are among the most extensively studied coral reef taxa, largely owing to their devastating impacts on live coral cover during population outbreaks. Much of this research has however, been conducted in the western Pacific, although it is now apparent that there are several distinct species of Acanthaster spp.

High-resolution characterization of the abiotic environment and disturbance regimes on the Great Barrier Reef, 1985-2017.

This data compilation synthesizes 36 static environmental and spatial variables, and temporally explicit modeled estimates of three major disturbances to coral cover on the Great Barrier Reef (GBR): (1) coral bleaching, (2) tropical cyclones, and (3) outbreaks of the coral-eating crown-of-thorns starfish Acanthaster cf. solaris. Data are provided on a standardized grid (0.

Unpredictable feeding impairs glucose tolerance in growing lambs.

Irregular eating is associated with insulin resistance and metabolic disease in adults but may affect young, growing children differently. We investigated the metabolic effects of unpredictable feeding in female juvenile lambs randomly assigned to receive, for six weeks, maintenance feed given twice daily in equal portions (Control Group, C; n = 24) or the same weekly feed amount in aliquots of variable size at unpredictable times (Unpredictable Group, U; n = 21). Intravenous glucose tolerance tests (IVGTT), insulin tolerance tests (ITT), and measurement of diurnal plasma cortisol concentrations were performed pre and post the dietary intervention.

Telaprevir: a hepatitis C NS3/4A protease inhibitor.

Background: Telaprevir is a hepatitis C NS3/4A protease inhibitor approved by the US Food and Drug Administration as part of combination therapy for the management of chronic hepatitis C virus (HCV) genotype 1 infection.

Objective: The article reviews published literature on telaprevir, including its chemistry, mechanism of action, resistance, pharmacodynamic and pharmacokinetic properties, drug interactions, therapeutic efficacy, HIV/HCV coinfection, pharmacogenomics, adverse events, pharmacoeconomics, and dosing and administration.

Methods: English-language literature was included.

Drotrecogin alfa (recombinant human activated protein C) for the treatment of severe sepsis.

Background: The search for a life-preserving drug to treat sepsis has increased understanding of the pathogenesis of the process but produced little in the way of successful treatments. The prospective, randomized, double-blind, placebo-controlled, Phase III, multicenter Recombinant Human Activated Protein C Worldwide Evaluation in Severe Sepsis (PROWESS) trial suggested that drotrecogin alfa--recombinant human activated protein C--significantly improved 28-day mortality rates in acute sepsis (P = 0.005).
