Pre-breeding canola for heat stress tolerance – a prototype facility for large-scale screening at flowering stage

This research is developing methodology to facilitate large-scale screening of heat stress tolerance in canola at flowering stage, and will identify heat tolerant germplasm for Australian plant breeders. The new methods and heat tolerant germplasm will be transferred to canola breeders, which will accelerate the future commercial release of heat tolerant varieties. Our aim is to help Australian growers to maintain canola productivity as temperatures rise in response to climate change

Combustion behaviour of some biodesulphurized coals assessed by TGA/DTA

Thermal analysis, i.e. TGA/DTA is used to study the changes in the combustion behaviour of microbially treated coals. In view of their high sulphur content and industrial significance three samples are under consideration, i.e. one lignite and two subbituminous from different region in Bulgaria. The differences in burning profiles can be related to structural changes resulted from biological treatments. The overall biological treatment generates these changes probably due to the oxidation process. Concerning organic sulphur biodesulphurization there is no change in any drastic mannerof the thermal characteristic parameters. In general, applied biotreatments provoke a complex influence on combustion coal behaviour. From one side a better ignition performance, a minor decrease in higher heating value and diminishing peak temperature of maximum weight loss rate for all biotreated samples are observed. From other side some decrease in the combustibility indicated by an increase in the combustion time and the end of combustion temperature are obvious. Also well determined decrease of self-heating temperature after biotreatments evolves high risk of spontaneous unmanageable coal combustion

Topical intranasal analgesia with EMLA for closed rhinoplasty

Background: Rhinoplasty is a traumatic procedure associated with postoperative pain. The purpose of this study is to determine the effect of topically administered intranasal EMLA 5% cream (lidocaine 25 mg/ prilocaine 25 mg) on the pain experienced in the postoperative period by patients who underwent closed rhinoplasty.Materials and methods: The study was conducted between October 2014 and May 2016 and included 66 patients divided in two groups, all of whom underwent closed rhinoplasty. In the first group (n = 33) when packaging and placing the nasal splint, each intranasal tampon (with Gelaspon) was applied with 2 ml EMLA 5% cream, and in the control group (n = 33) 2 ml Deflamol ointment was applied on each tampon. All patients were operated under general anesthesia after introduction with intravenous Propofol and maintenance of the anesthesia with Sevoflurane and opioid analgesic. After placing the patient under general anesthesia, the otorhinolaryngologist carries on with local infiltration anesthesia with a solution of lidocaine 0.5%and adrenaline 1: 100,000 4-6 ml. All patients received oral antibiotic treatment (with Klacid or Zinnat) for the period of the packaging. No corticosteroids were included in the therapeutic scheme. Post-operative pain was assessed on a visual analog scale on the 1, 3, 6, 12, 24, 48 hour in the patients of both groups.Results: The statistical analysis shows that there is a significant differencein reported results for the treatment of post-operative pain on the 1, 6 and 12 hour period in both groups studied. Four of the patients (12%) in the EMLA group had results from the VAS > 40 mm and required administration of a non-opioid analgesic in the first 24 hours, whilst in the control group this number of patients was 13 (39%).Conclusion: Intranasal application EMLA 5% cream in the packaging for reducing postoperative pain in patients who underwent closed rhinoplasty proves to be a simple and effective technique, in which we have not found adverse side effects in the study group patients despite this off label usage

A Giant Hand Lipoma As a Rare Cause of Secondary Carpal Tunnel Syndrome - a Case Report

Introduction: Lipomas are a rare cause of compressive neuropathy and they lead to atypical clinical presentation that can mimic carpal tunnel syndrome. Case presentation: The authors describe a rare presentation of a carpal tunnel syndrome recurrence after a hand giant lipoma, presenting with rapidly compression neuropathy of the median nerve, 6 months after de primary surgery. Discussion: Lipomas are common benign soft tumours. Their occurrence in the hand remains rare and they rarely cause secondary entrapment neuropathies. Carpal tunnel syndrome is mostly idiopathic and bilateral. Local factors should be suspected when these neuropathies present with atypical symptomatology or even when they recur after primary conventional surgical release. Investigation should consider images studies as this correct preoperative assessment leads to successful diagnosis and treatment.info:eu-repo/semantics/publishedVersio

Necrotising sinusitis with orbital complication in patient with macrophage activation syndrome (MAS)

Background: Macrophage activation syndrome (MAC) is a potentially fatal clinical-laboratory syndrome of uncontrolled hyperinflammation arising as a result of hereditary or acquired immune-mediated processes of cellular overactivation and nonmalignant proliferation of tissue macrophages/histiocytes, which can cause multiorgan failure.Case report: We present a clinical case of 15-years old child, who was diagnosed with juvenile idiopathic arthritis in 2019. The disease started with macrophage activation syndrome. In the next years the child had multiple hospitalizations in the Pediatrics clinic, but in the course of the disease it developed the picture of severe necrotic pansinuitis with an orbital complication, which required an immediate surgical intervention. Ever since the child had an ongoing necrotizing process in the area of the nasal passages, sinuses, upper jaw and hard palate. Other complications were breakthrough of the hard palate, loss of healthy teeth from the upper dentition and creation of direct communication between the oral cavity and the left maxillary sinus.Conclusions: The diagnosis of MAS is difficult to make, but increased awareness of this disease is an essential for its recognition. The struggle with autoimmune diseases often lasts for years with periods of exacerbation and remission of symptoms. Complications related to them can affect different organs and systems and require interdisciplinary approach

The discrimination of abrupt changes in speed and direction of visual motion

AbstractA random dot pattern that moved within an invisible aperture was used to present two motions contiguously in time. The motions differed slightly either in speed (Experiments 1 and 3) or in direction (Experiments 2 and 4) and the subject had to discriminate the sign of the change (e.g. increment or decrement). The same discrimination task was performed when the two motions were temporally separated by 1 s. In Experiments 1 and 2 discrimination thresholds were measured with motion durations of 0.125, 0.25, 0.5 and 1.0 s and mean speeds of 2, 4, 8, and 16°/s. In Experiments 3 and 4 thresholds were measured with aperture widths of 5 and 20 cm. The discrimination of contiguous motions progressively deteriorated with decreasing duration and mean speed of motion. For the lowest value of duration the Weber fraction for contiguous speeds was more than three times as the Weber fractions for separate speeds. For the same low value of duration the thresholds for discrimination of direction of contiguous motions were only about 50% higher than the thresholds for separate motions. The Weber fraction for contiguous speeds was ca. three times higher with the smaller aperture than with the larger one, provided the ratio ‘aperture width/mean speed’ (i.e. the lifetime of the moving dots) was less than 0.3 s. Aperture width did not affect the discrimination of direction of contiguous motions. The discrimination of contiguous motions is discussed together with the known data for detection of changes in speed and direction. It is suggested that both, detection of changes in speed and discrimination of the sign of speed changes, may be performed by a common visual mechanism

Soil water repellence increased early wheat growth and nutrient uptake

Purpose Soil water repellence causes uneven soil wetting which can constrain dryland crop and pasture establishment and yield. The same processes are likely to affect nutrient availability from soil and fertiliser, but the effects of repellence on crop growth and nutrition per se have seldom been reported. Here, we investigated early wheat (Triticum aestivum cv. Mace) growth and nutrient uptake responses to repellence. Methods Wheat was furrow-sown in severely repellent sandy loam soil (with a wettable furrow base to allow for germination) or completely wettable soil, under uniform plant density and variable topsoil thickness (20 or 100 mm) and fertiliser band placement (below or away from the seed). Tiller number, shoot dry matter, shoot N concentration, total nutrient uptake, and root length density (RLD) were determined. Results Contrary to expectations, repellence significantly increased tiller number (by up to 2 tillers per plant), shoot dry matter (by 82%), shoot N concentration (by 0.3% N), and total nutrient uptake (by 87%) at 51 days after sowing, regardless of topsoil thickness and fertiliser placement. In the furrow, RLD of repellent treatments was also nearly double that in wettable treatments when fertiliser was banded below the seed. Results suggest that preferential soil wetting of the furrow in repellent treatments favoured plant nutrient uptake under regular but low water supply. Conclusion We conclude that for water-repellent soils with limited water supply, water harvesting techniques such as furrow sowing and banding wetting agents could boost water and nutrient uptake and early crop growth
