Summary: Evolutionary information in the form of a Position-Specific Scoring Matrix (PSSM) is a widely used and highly informative representation of protein sequences. Accordingly, PSSM-based feature descriptors have been successfully applied to improve the performance of various predictors of protein attributes. Even though a number of algorithms have been proposed in previous studies, there is currently no universal web server or toolkit available for generating this wide variety of descriptors...

Vaccination of cattle against bovine tuberculosis could be a valuable control strategy, particularly in countries faced with intractable ongoing infection from a disease reservoir in wildlife. A field vaccination trial was undertaken in New Zealand. The trial included 1286 effectively free-ranging cattle stocked at low densities in a remote 7600ha area, with 55% of them vaccinated using Mycobacterium bovis BCG (Danish strain 1311). Vaccine was administered orally in all but 34 cases (where it was injected)...

Laparoscopic cholecystectomy (LC) is performed for gallbladder stones and cholecystitis in a large number of elderly patients. However, the safety of LC in the elderly is questioned. The aim of this study was to investigate predictive factors for the incidence of postoperative complications and deaths after LC in patients aged 80 years and older. Data from 85 elderly patients who underwent LC between January 2005 and December 2015 were prospectively collected in a database at our hospital. The following factors were compared for the occurrence of postoperative complications and deaths:age, gender, Body Mass Index, laboratory date, severity grade of cholecystitis, comorbidity of choledocholithiasis, conversion to open cholecystectomy, early or delayed LC, amount of time from onset to LC, operative duration, blood loss, and the following scoring systems for predicting risk of surgery:ECOG-PS, ASA, SIRS, CONUT, POSSUM, SAS, E-PASS...

The Physiological and Operative Severity Score for the Enumeration of Mortality and Morbidity (POSSUM) is widely used to predict surgical complications affecting various organs. However, there are few reports about objective evaluation methods for head and neck surgery. In this study, we retrospectively examined the association between POSSUM score and actual surgical complications of head and neck reconstruction surgery. In total, 711 patients who underwent head and neck reconstruction after cancer extirpation between January 2007 and January 2015 were studied...

BACKGROUND: Cortisol levels rise with the physiological stress of surgery. Previous studies have used older, less-specific assays, have not differentiated by severity, or only studied procedures of a defined type. The aim of this study was to examine this phenomenon in surgeries of varying severity using a widely used cortisol immunoassay. METHODS: Euadrenal patients undergoing elective surgery were enrolled prospectively. Serum samples were taken at 8 am on surgical day, induction and 1 hr, 2 hr, 4 hr and 8 hr after...

The occurrence and rate of wildlife-vehicle collisions are related to both anthropocentric and environmental variables, however, few studies compare collision risks for multiple species within a model framework that is adaptable and transferable. Our research compares collision risk for multiple species across a large geographic area using a conceptually simple risk framework. We used six species of native terrestrial mammal often involved with wildlife-vehicle collisions in south-east Australia. We related collisions reported to a wildlife organisation to the co-occurrence of each species and a threatening process (presence and movement of road vehicles)...

Pregnancy in mammals requires remodeling of the uterus to become receptive to the implanting embryo. Remarkably similar morphological changes to the uterine epithelium occur in both eutherian and marsupial mammals, irrespective of placental type. Nevertheless, molecular differences in uterine remodeling indicate that the marsupial uterus employs maternal defences, including molecular reinforcement of the uterine epithelium, to regulate embryonic invasion. Non-invasive (epitheliochorial) embryonic attachment in marsupials likely evolved secondarily from invasive attachment, so uterine defences in these species may prevent embryonic invasion...

We sought to compare the weight of patient's medical records (MRW) to that of standardised surgical risk scoring systems in predicting postoperative hospital stay, morbidity, and mortality in patients with hip fracture. Patients admitted for surgical treatment of a newly diagnosed hip fracture over a 3-month period were enrolled. Patients with documented morbidity or mortality had significantly heavier medical records. The MRW was equivalent to the age-adjusted Charlson co-morbidity index and better than the American Society of Anaesthesiologists physical status score (ASA), the Physiological and Operative Severity Score for the enUmeration of Mortality and Morbidity (POSSUM,) and Portsmouth-POSSUM score (P-POSSUM) in correlation with length of hospital admission, p = ...

The occurrence of Francisella tularensis outside of endemic areas, such as North America and Eurasia, has been enigmatic. We report the metagenomic discovery and isolation of F. tularensis ssp. holarctica biovar japonica from diseased ringtail possums in Sydney, Australia. This finding confirms the presence of F. tularensis in the Southern Hemisphere.

BACKGROUND: Q fever is a zoonotic infection caused by Coxiella burnetii. Endemic Q fever has long been recognised in north Queensland, with north Queensland previously acknowledged to have the highest rate of notification in Australia. In this retrospective study, we reviewed the demographics and exposure of patients diagnosed with Q fever in an endemic region of north Queensland, to identify trends and exposure factors for the acquisition of Q fever. METHODS: A retrospective study looking at patients in the region that had tested positive for Q fever by case ascertainment between 2004 and 2014...

The eastern pygmy possum (Cercartetus nanus) is a small marsupial that can express spontaneous short bouts of torpor, as well as multi-day bouts of deep hibernation. To examine heart rate (fH) control at various stages of torpor in a marsupial hibernator, and to see whether fH variability differs from that of deep placental hibernators, we used radiotelemetry to measure ECG and body temperature (Tb) while measuring the rate of O2 consumption and ventilation. fH and O2 consumption rate during euthermia were at a minimum (321±34 beats min(-1), 0...

According to the TASC II and the Russian National Guidelines on management of patients with lower limb arterial diseases, in patients with type C and D lesions of the arterial bed performing aortofemoral bifurcation bypass grafting is preferable. Laparoscopic technique makes it possible to combine advantages of minimally invasive surgery with well-known remote results of open reconstructive operations on the aortoiliac segment. The study included a total of 54 patients undergoing treatment at the Cardiosurgical Department of Clinic No 1 of the Volgograd State Medical University over the period from January 2012 to September 2015...

Thermal properties of tree hollows play a major role in survival and reproduction of hollow-dependent fauna. Artificial hollows (nest boxes) are increasingly being used to supplement the loss of natural hollows; however, the factors that drive nest box thermal profiles have received surprisingly little attention. We investigated how differences in surface reflectance influenced temperature profiles of nest boxes painted three different colors (dark-green, light-green, and white: total solar reflectance 5.9%, 64...

A molecular survey was conducted to provide baseline information on the prevalence, genetic diversity and potential clinical impacts of blood-borne and enteric protozoans in native wild mammals from the Northern Territory (NT). A total of 209 blood and 167 faecal samples were collected from four target species; the northern brown bandicoot (Isoodon macrourus), common brushtail possum (Trichosurus vulpecula), northern quoll (Dasyurus hallucatus) and brush-tailed rabbit-rat (Conilurus penicillatus). Blood samples were screened by PCR at the 18S rRNA gene for trypanosomes, piroplasms and haemogregarines, with faecal samples tested for Cryptosporidium spp...

The formation of a placenta is critical for successful mammalian pregnancy and requires remodelling of the uterine epithelium. In eutherian mammals, remodelling involves specific morphological changes that often correlate with the mode of embryonic attachment. Given the differences between marsupial and eutherian placentae, formation of a marsupial placenta may involve patterns of uterine remodelling that are different from those in eutherians. Here we present a detailed morphological study of the uterus of the brushtail possum (Trichosurus vulpecula; Phalangeridae) throughout pregnancy, using both scanning and transmission electron microscopy, to identify whether uterine changes in marsupials correlate with mode of embryonic attachment as they do in eutherian mammals...

Bovine tuberculosis (TB) is managed in New Zealand largely via population reduction of the major wildlife disease reservoir of Mycobacterium bovis, the introduced brushtail possum Trichosurus vulpecula. New Zealand aims to eradicate M. bovis infection from its livestock and wildlife within 40 years, as the culmination of progressive regional eradication programmes. Declarations of regional eradication are decided after extensive possum population control and post-control surveillance; hence, we developed a modelling framework, based on eco-epidemiological simulation data, to provide cost-evaluated options for deciding when to make these declarations...

Background and study aims Adenomas of the duodenum and ampulla are uncommon. For lesions ≤ 20 mm in size and confined to the papillary mound, endoscopic resection is well supported by systematic study. However, for large laterally spreading lesions of the duodenum or papilla (LSL-D/P), surgery is often performed despite substantial associated morbidity and mortality. We aimed to compare actual endoscopic outcomes of such lesions and costs with those predicted for surgery using validated prediction tools...
