In recent years, the two issues of climate change including elevated CO2 etc., and resistance of transgenic Bt crops against non-target insect pests have received widespread attention. Elevated CO2 can affect the herbivorous insects. To date, there is no consensus about the effect of elevated CO2 on the suck-feeding insect pests (non-target insect pests of transgenic Bt crops). Its effects on the suck-feeding behavior have rarely been reported. In this study, CO2 levels were set up in artificial climate chamber to examined the effects of ambient (400 μL·L-1 ) and double-ambient (800 μL·L-1 ) CO2 levels on the suck-feeding behavior, growth, development, and reproduction of the non-target insect pest of transgenic Bt rice, brown planthopper, Nilaparvata lugens...

BACKGROUND: Aboriginal people with cancer experience worse outcomes than other Australians for a range of complex and interrelated reasons. A younger age at diagnosis, higher likelihood of more advanced cancer or cancer type with poorer prognosis, geographic isolation and cultural and language diversity mean that patient pathways are potentially more complex for Aboriginal people with cancer. In addition, variation in the quality and acceptability of care may influence cancer outcomes...

Antimicrobial resistance is a public health emergency, placing veterinary antimicrobial use under growing scrutiny. Antimicrobial stewardship, through appropriate use of antimicrobials, is a response to this threat. The need for antimicrobial stewardship in Australian veterinary practices has had limited investigation. A 2016 survey undertaken to investigate antimicrobial usage patterns by Australian veterinarians found that antimicrobial dose rates were varied and often inappropriate. Doses of procaine penicillin in horses and cattle were often low, with 68% and 90% of respondents, respectively, reporting doses that were unlikely to result in plasma concentrations above minimum inhibitory concentrations for common equine and bovine pathogens...

The marine environment is filled with biotic and abiotic sounds. Some of these sounds predict important events that influence fitness while others are unimportant. Individuals can learn specific sound cues and 'soundscapes' and use them for vital activities such as foraging, predator avoidance, communication and orientation. Most research with sounds in elasmobranchs has focused on hearing thresholds and attractiveness to sound sources, but very little is known about their abilities to learn about sounds, especially in benthic species...

Medical case management (MCM) is a core medical service in The Ryan White HIV/AIDS Program and aims to provide treatment and care for people living with HIV/AIDS by engaging, identifying and eliminating barriers to HIV care. Little research has examined the impact of this intervention; therefore, the purpose of this study was to examine the how MCM affects HIV clinical outcomes. The study took place at a midwestern, outpatient infectious diseases clinic. This study utilized a longitudinal, retrospective study design to analyze to the impact of MCM engagement on HIV clinical outcomes (viral loads, CD4 counts) from 2009 to 2015 as a time-varying predictor...

REVIEW
Thillai Punitha, Siew-Moi Phang, Joon Ching Juan, John Beardall
Vanadium-dependent haloperoxidases (V-HPO), able to catalyze the reaction of halide ions (Cl- , Br- , I- ) with hydrogen peroxide, have a great influence on the production of halocarbons, which in turn are involved in atmospheric ozone destruction and global warming. The production of these haloperoxidases in macroalgae is influenced by changes in the surrounding environment. The first reported vanadium bromoperoxidase was discovered 40 years ago in the brown alga Ascophyllum nodosum. Since that discovery, more studies have been conducted on the structure and mechanism of the enzyme, mainly focused on three types of V-HPO, the chloro- and bromoperoxidases and, more recently, the iodoperoxidase...

Among their responses to microbial infection, plants deploy an arsenal of natural antibiotic products. These historically have been identified on the basis of their antibiotic activity in vitro, which leaves open the question of their relevance to defense in planta. The vast majority of such natural products from the important crop plant rice (Oryza sativa) are diterpenoids whose biosynthesis proceeds via either ent- or syn- copalyl diphosphate (CPP) intermediates, and which were isolated on the basis of their antibiotic activity against the fungal blast pathogen Magnaporthe oryzae...

Ribosome biogenesis involves numerous preribosomal RNA (pre-rRNA) processing events to remove internal and external transcribed spacer sequences, ultimately yielding three mature rRNAs. Removal of the internal transcribed spacer 2 spacer RNA is the final step in large subunit pre-rRNA processing and begins with endonucleolytic cleavage at the C2 site of 27SB pre-rRNA. C2 cleavage requires the hierarchical recruitment of 11 ribosomal proteins and 14 ribosome assembly factors. However, the function of these proteins in C2 cleavage remained unclear...

OBJECTIVES: Diet and fluid management can reduce mortality, serious comorbidities, and debilitating symptoms in patients on hemodialysis, but restrictions may also be a major burden, and nonadherence remains high. We aimed to describe the perspectives and experiences of patients on hemodialysis regarding their dietary management to understand both facilitators and barriers to adherence and to identify strategies to improve care. DESIGN AND METHODS: Semi-structured interviews were conducted with 35 people on maintenance hemodialysis from six dialysis units in New South Wales, Australia...

BACKGROUND AND AIMS: Angiotensin receptor blockers (ARB) and angiotensin converting enzyme inhibitors (ACEI) reduce cardiovascular events in the general population. Maintenance hemodialysis (MHD) patients are at high cardiovascular risk but few studies have directly addressed the comparative efficacy of these drugs. MHD disrupts the normally atheroprotective actions of high density lipoprotein (HDL), therefore, we compared ACEI or ARB treatment on HDL functions in MHD. METHODS AND RESULTS: HDL was isolated at the starting point (pre) and 3-6 months later (post) in 30 MHD randomly assigned to placebo, ramipril or valsartan...

The fucose-containing sulfated polysaccharides (syn. fucoidans) from brown algae exhibit a wide range of bioactivities and are therefore considered promising candidates for health-supporting and medical applications. During the past three decades, research on isolation, molecular characterization, and screening of in vitro and in vivo pharmacological activities has significantly increased. Until now, however, fucoidans are only used as ingredients in cosmetics and food supplements, especially due to the proclaimed antioxidant activities of fucoidan...

Combined traumatic brain injury (TBI) and hemorrhagic shock (HS) remains a leading cause of preventable death worldwide. Mesenchymal stem cell-derived exosomes have demonstrated promise in small animal models of neurologic injury. To investigate the effects of exosome treatment in a clinically realistic large animal model, Yorkshire swine were subjected to TBI and HS. Animals were maintained in shock for 2 hours prior to resuscitation with normal saline (NS). Animals were then either resuscitated with NS (3 x volume of shed blood) or with the same volume of NS with delayed exosome administration (1x10<sup>13</sup> particles/4ml) (n=5/cohort)...

It is widely recognized that burnout is prevalent in medical culture and begins early in training. Studies show pediatricians and pediatric trainees experience burnout rates comparable to other specialties. Newly developed Accreditation Council for Graduate Medical Education (ACGME) core competencies in professionalism and personal development recognize the unacceptably high resident burnout rates and present an important opportunity for programs to improve residents experience throughout training. These competencies encourage healthy lifestyle practices and cultivation of self-awareness, self-regulation, empathy, mindfulness, and compassion&mdash;a paradigm shift from traditional medical training underpinned by a culture of unrealistic endurance and self-sacrifice...
