Faculty of Science, Medicine and Health - Papers: Part B

Flour, typically derived from wheat, rye, corn and rice is a pantry staple, providing structure to bread and baked goods. This study aimed to provide a cross-sectional analysis of flour for home baking, highlighting the nutrition composition of whole grain flour and identifying novel categories. An audit was undertaken in February 2020, in four major supermarkets in metropolitan Sydney (Aldi, Coles, IGA and Woolworths). Ingredient lists, Nutrition Information Panel, claims, and country of origin were collected. The median and range were calculated for energy, protein, fat, saturated fat, carbohydrate, sugars, dietary fibre and sodium. Overall, 130 products were collected, including …

Nutritional Status According To The Mini Nutritional Assessment Predicts Speed And Degree Of Functional Improvement And Discharge Outcomes In Rehabilitation Patients, Kelly Lambert, Emily Taylor, Steven Bowden, Karen E. Charlton

Faculty of Science, Medicine and Health - Papers: Part B

This retrospective observational study evaluated the association between nutritional status, functional ability and discharge outcomes. Data from 1430 older rehabilitation patients (43% male, median age 79 years, interquartile range: 74–84) were analyzed. One fifth (20.6%, n = 294) of patients were malnourished on admission to rehabilitation. Three important findings were evident. Firstly, nutritional status on admission to rehabilitation was associated with reduced functional, motor, cognitive and feeding scores on admission and discharge (all P < 0.05). Secondly, malnutrition at admission was associated with significantly slower gains in rehabilitation. Finally, malnutrition at admission was associated with significantly higher odds of a decline in functional ability during admission (OR 3.95; 95% CI: 2.14–7.27), and almost three times greater odds of additional care requirements on discharge (OR: 2.9 ((95% CI: 1.02–8.3). The nutritional status of patients on admission to inpatient rehabilitation is a predictor of both the speed and degree of rehabilitation gains and discharge outcomes.

While all GAS genomes contain genes for Mga and C5a peptidase, the intervening genes encoding M and M-like proteins vary between strains. The genetic make-up of the Mga regulon of GAS was characterized by utilizing a collection of 1,688 GAS genomes that are representative of the global GAS population. Sequence variations were examined with multiple alignments, and the expression of all core Mga regulon genes was examined by quantitative reverse transcription-PCR in a …

What Is Underneath The Juvenile Ordovician Macquarie Arc (Eastern Australia)? A Question Resolved Using Silurian Intrusions To Sample The Lower Crust, Qing Zhang, Allen Phillip Nutman, Solomon Buckman, Vickie C. Bennett

Faculty of Science, Medicine and Health - Papers: Part B

2020 International Association for Gondwana Research The Ordovician intra-oceanic Macquarie Arc of eastern Australia collided with the eastern Gondwanan margin at ~440 Ma. However, the deep crustal architecture resulting from this assembly is poorly known. This is addressed here by a zircon U-Pb-Hf study of the post-assembly Silurian Browns Creek Intrusive Complex and Davies Creek Granite dykes that intrude into the arc, and not adjacent Gondwanan sedimentary sequences. Zircon U[sbnd]Pb dating integrated with CL imagery indicate two igneous phases at 430-437 Ma and 420-426 Ma and a zircon recrystallisation phase at 395-396 Ma attributed to a late thermal event. The …

Neanderthals were once widespread across Europe and western Asia. They also penetrated into the Altai Mountains of southern Siberia, but the geographical origin of these populations and the timing of their dispersal have remained elusive. Here we describe an archaeological assemblage from Chagyrskaya Cave, situated in the Altai foothills, where around 90,000 Middle Paleolithic artifacts and 74 Neanderthal remains have been recovered from deposits dating to between 59 and 49 thousand years ago (age range at 95.4% probability). Environmental reconstructions suggest that the Chagyrskaya hominins were adapted to the dry steppe and hunted bison. Their distinctive toolkit closely resembles Micoquian …

2020 The Authors Dermal fibroblasts were donated by a 43 year old male patient with clinically diagnosed familial amyotrophic lateral sclerosis (ALS), carrying the SOD1E101G mutation. The induced pluripotent stem cell (iPSC) line UOWi007-A was generated using repeated mRNA transfections for pluripotency transcription factors Oct4, Klf4, Sox2, c-Myc, Lin28 and Nanog. The iPSCs carried the SOD1E101G genotype and had a normal karyotype, expressed expected pluripotency markers and were capable of in vitro differentiation into endodermal, mesodermal and ectodermal lineages. This iPSC line may be useful for investigating familial ALS resulting from a SOD1 E101G mutation.

Verifying anthropogenic carbon dioxide (CO2) emissions globally is essential to inform about the progress of institutional efforts to mitigate anthropogenic climate forcing. To monitor localized emission sources, spectroscopic satellite sensors have been proposed that operate on the CO2 absorption bands in the shortwave-infrared (SWIR) spectral range with ground resolution as fine as a few tens of meters to about a hundred meters. When designing such sensors, fine ground resolution requires a trade-off towards coarse spectral resolution in order to achieve sufficient noise performance. Since fine ground resolution also implies limited ground coverage, such sensors are envisioned to fly in fleets …

The First Australian Plant Foods At Madjedbebe, 65,000-53,000 Years Ago, S Florin, Andrew Fairbairn, May Nango, Djaykuk Djandjomerr, Ben Marwick, Richard Fullagar, Mike Smith, Lynley Wallis, Christopher Clarkson

Faculty of Science, Medicine and Health - Papers: Part B

2020, The Author(s). There is little evidence for the role of plant foods in the dispersal of early modern humans into new habitats globally. Researchers have hypothesised that early movements of human populations through Island Southeast Asia and into Sahul were driven by the lure of high-calorie, low-handling-cost foods, and that the use of plant foods requiring processing was not common in Sahul until the Holocene. Here we present the analysis of charred plant food remains from Madjedbebe rockshelter in northern Australia, dated to between 65 kya and 53 kya. We demonstrate that Australia's earliest known human population exploited a …

Antibiotic-Induced Mutagenesis: Under The Microscope, Sarah Revitt-Mills, Andrew Robinson

Faculty of Science, Medicine and Health - Papers: Part B

Copyright 2020 Revitt-Mills and Robinson. The development of antibiotic resistance poses an increasing threat to global health. Understanding how resistance develops in bacteria is critical for the advancement of new strategies to combat antibiotic resistance. In the 1980s, it was discovered that certain antibiotics induce elevated rates of mutation in bacteria. From this, an "increased evolvability" hypothesis was proposed: antibiotic-induced mutagenesis increases the genetic diversity of bacterial populations, thereby increasing the rate at which bacteria develop antibiotic resistance. However, antibiotic-induced mutagenesis is one of multiple competing factors that act on bacterial populations exposed to antibiotics. Its relative importance in shaping …

Molecular data are used to reconstruct inter-specific and generic relationships and support morphological species hypotheses. Phylogenetic analysis places all three Australian Amobia species together with Amobia signata (Meigen, 1824) (a …

Severe Childhood And Adulthood Stress Associates With Neocortical Layer-Specific Reductions Of Mature Spines In Psychiatric Disorders, Dominic Kaul, Caine C. Smith, Julia Stevens, Anna S. Fröhlich, Elisabeth B. Binder, Naguib Mechawar, Sibylle G. Schwab, Natalie Matosin

Faculty of Science, Medicine and Health - Papers: Part B

Severe stress exposure causes the loss of dendritic spines on cortical pyramidal neurons and induces psychiatric-like symptoms in rodent models. These effects are strongest following early-life stress and are most persistent on apical dendrites. However, the long-term impacts and temporal effects of stress exposure on the human brain remain poorly understood. Using a novel postmortem cohort of psychiatric cases with severe stress experienced in childhood, adulthood, or no severe stress, and matched controls, we aimed to determine the impact of stress timing on pyramidal neuron structure in the human orbitofrontal cortex (OFC). We performed Golgi Cox staining and manually measured …

Rapid High-Yield Expression And Purification Of Fully Post-Translationally Modified Recombinant Clusterin And Mutants, Sandeep Satapathy, Rebecca Dabbs, Mark R. Wilson

Faculty of Science, Medicine and Health - Papers: Part B

The first described and best known mammalian secreted chaperone, abundant in human blood, is clusterin. Recent independent studies are now exploring the potential use of clusterin as a therapeutic in a variety of disease contexts. In the past, the extensive post-translational processing of clusterin, coupled with its potent binding to essentially any misfolded protein, have meant that its expression as a fully functional recombinant protein has been very difficult. We report here the first rapid and high-yield system for the expression and purification of fully post-translationally modified and chaperone-active clusterin. Only 5–6 days is required from initial transfection to harvest …

Five-Membered Cyclic Sulfamidate Imines: Versatile Scaffolds For Organic Synthesis, Quoc Hoang Pham, Christopher J. T Hyland, Stephen G. Pyne

Faculty of Science, Medicine and Health - Papers: Part B

In recent years, five-membered ring cyclic sulfamidate imines (5H-1,2,3-oxathiazole 2,2-dioxides) have received increasing attention as useful precursors for the stereoselective synthesis of many valuable heterocycles. Bearing a reactive N-sulfonyl imine moiety as part of the stereodefined skeleton, this sulfamidate imine platform has been utilised as a substrate in many reactions, including nucleophilic additions and reductions, to prepare highly functionalised cyclic sulfamidates. In addition, cyclic sulfamidate imines can also readily participate as nucleophiles in many chemical transformations, owing to the reactivity of the acidic proton(s) adjacent to the imine moiety. This short review highlights recent developments involving cyclic sulfamidate imines, including …

The Effect Of Residual Signal On Dose Measurements Using Met-Pirir Signals From K-Feldspar, Xue Rui, Bo Li, Yujie Guo

Faculty of Science, Medicine and Health - Papers: Part B

© 2020 Elsevier B.V. Overestimation in dose recovery results was observed at high doses (>1000 Gy) when a single-aliquot regenerative-dose (SAR) procedure is applied to the multiple-elevated-temperature post-IR IRSL (MET-pIRIR) signals from potassium-rich feldspar (K-feldspar) grains from the Nihewan Basin. Such overestimation results from the non-bleachable (residual) signals that were not appropriately corrected for. A signal-subtraction method was proposed to solve this problem, which involves building growth curves for the bleachable and non-bleachable signals. Here we modelled the effect of residual signal on equivalent dose (De) and found that even a small amount of residual signal may give rise …

Discrimination Between Protonation Isomers Of Quinazoline By Ion Mobility And Uv-Photodissociation Action Spectroscopy, Samuel Marlton, Benjamin Mckinnon, Boris Ucur, James Bezzina, Stephen Blanksby, Adam J. Trevitt

Faculty of Science, Medicine and Health - Papers: Part B

The influence of oriented electric fields on chemical reactivity and photochemistry is an area of increasing interest. Within a molecule, different protonation sites offer the opportunity to control the location of charge and thus orientation of electric fields. New techniques are thus needed to discriminate between protonation isomers in order to understand this effect. This investigation reports the UV-photodissociation action spectroscopy of two protonation isomers (protomers) of 1,3-diazanaphthalene (quinazoline) arising from protonation of a nitrogen at either the 1- or 3-position. It is shown that these protomers are separable by field-asymmetric ion mobility spectrometry (FAIMS) with confirmation provided by UV-photodissociation …
