    Abstract Background: An LC-MS/MS method was developed for determination and confirmation of tilmicosin in bovine, swine, chicken, and turkey tissues (liver, kidney, muscle, and skin/fat) and bovine milk.
    Objective: The method was subjected to single-laboratory validation to establish method performance parameters.
    Method: Animal tissues and bovine milk were fortified at four concentrations ranging from 0.5 times the lowest maximum residue limit (MRL) or tolerance to 2 times the highest MRL or tolerance considering the Codex and EU MRLs and the US tolerances in the various tissues and milk studied. Incurred tissues were analyzed to verify the precision of the method.
    Results: The data demonstrated linearity of matrix-matched calibration curves using a weighted (1/×) regression. Recoveries varied from 83.3 to 107.1%. Repeatability precision (RSDr) ranged from 0.465 to 13.4% and intermediate precision (RSDi) ranged from 2.24 to 14.7% in fortified tissue. Repeatability of the method was verified in incurred tissues, ranging from 3.41 to 16.0%. The limits of detection and quantitation of the method are presented and vary by matrix. One confirmatory transition ion was examined across all matrixes and met US and EU criteria for mass spectrometry confirmation. The method was shown to be robust when small changes in method parameters were made, and stability of the analyte in fortified tissues, extracts, standard solutions, and matrix-matched standards was estimated.
    Conclusions: The data satisfy the requirements of the AOAC Stakeholder Panel for Veterinary Drug Residue Methods for single-laboratory validation studies and the U.S. Food and Drug Administration Center for Veterinary Medicine Guidance for Industry #208 (VICH GL49).
    Highlights: The LC-MS/MS method was demonstrated to be suitable for determination and confirmation of tilmicosin residues in bovine, swine, chicken, and turkey tissues and bovine milk based on Codex and EU MRLs and US tolerances.

    Abstract Forest productivity depends on resource acquisition by ephemeral roots and leaves. A combination of intrinsic and environmental factors influences ephemeral organs; however, difficulties in studying belowground organs impede mechanistic understanding of fine-root production and turnover. To quantify factors controlling fine-root dynamics, we grew a deciduous hardwood (Populus deltoides Bartr.) and an evergreen conifer (Pinus taeda L.) with distinct soil moisture and nutrient availability treatments. We monitored fine-root dynamics with minirhizotrons for 6 years during early stand development and expressed results on a root length, biomass and mortality-risk basis. Stand development and other intrinsic factors consistently influenced both species in the same direction and by similar magnitude. Live-root length increased to a peak during establishment and slowly declined after roots of neighboring trees overlapped. Root longevity was highest during establishment and decreased thereafter. Root longevity consistently increased with depth of appearance and initial root diameter. Season of appearance affected root longevity in the following order: spring > summer > fall > winter. The influence of soil resource availability on fine-root dynamics was inconsistent between species, and ranked below that of rooting depth, initial diameter, stand development and phenology. Fine-root biomass either increased or was unaffected by greater resource availability. Fine-root production and live root length decreased with irrigation for both species, and increased with fertilization only for poplar. Fine-root mortality risk both increased and decreased depending on species and amendment treatment. Differing responses to soil moisture and nutrient availability between species suggests we should carefully evaluate generalizations about the response of fine-root dynamics to resource availability. While attempting to describe and explain carbon allocation to fine-root production and turnover, modelers and physiologists should first consider consistent patterns of allocation caused by different depth, diameter, stand development, phenology and species before considering allocation due to soil resource availability.

    Abstract We present the case of a 14 year old who underwent laparoscopic marsupialisation of a splenic cyst. Postoperative ultrasound demonstrated an echogenic collection in the surgical bed that was initially misdiagnosed as an infected collection/abscess due to its sonographic appearances but was finally correctly identified as haemostatic material that had been packed into the surgical cavity. We subsequently constructed a tissue phantom containing a compressed ball of SURGICEL (r) Absorbable Hemostat and demonstrated that it showed identical sonographic appearances. Haemostatic agents such as oxidised cellulose are often packed within the operative bed to control microvascular haemorrhage. These agents can be observed on a variety of postoperative imaging modalities, in particular ultrasound and computed tomography, and may cause diagnostic error. The critical importance of understanding the details of the surgical procedure and effective communication between the surgical team and ultrasound practitioner is emphasised to minimise the risk of misdiagnosis and unnecessary further imaging and radiological/surgical intervention.

    Abstract The sigma-1 and sigma-2 receptors were first discovered in the 1960s and were thought to be a form of opioid receptors initially. Over time, more was gradually learned about these receptors, which are actually protein chaperones, and many of their unique or unusual properties can contribute to a range of important new therapeutic applications. These sigma receptors translocate in the body and regulate calcium homeostasis and mitochondrial bioenergetics and they also have neuroprotective effects. The ligands to which these sigma receptors respond are several and dissimilar, including neurosteroids, neuroleptics, and cocaine. There is controversy as to their endogenous ligands. Sigma receptors are also involved in the complex processes of cholesterol homeostasis and protein folding. While previous work on this topic has been limited, research has been conducted in multiple disease states, such as addiction, aging. Alzheimer's disease, cancer, psychiatric disorders, pain and neuropathic pain, Parkinson's disease, and others. There is currently increasing interest in sigma-1 and sigma-2 receptors as they provide potential therapeutic targets for many disease indications.

    Abstract Background: Regional variations in healthcare outcomes in England have been historically reported. This study analyses the variations in long term colorectal cancer survival across different regions in England.
    Methods: Relative survival analysis of population data obtained from all cancer registries in England between 2010 and 2014.
    Results: Totally, 167,501 patients were studied. Regions in the southern England had better outcomes with Southwest and Oxford registries having 63.5 and 62.7% 5 year relative survival. In contrast, Trent and Northwest cancer registries had 58.1% relative survival (p < 0.01). The regions in the north fared below the national average. The survival outcomes reflected socio-economic deprivation status, the best performing regions in the south having low levels of deprivation (5.3 and 6.5% having maximum deprivation in Southwest and Oxford, respectively). The regions with worst long term cancer outcomes had high levels of deprivation with 25% and 17% having high levels of deprivation in Northwest and Trent regions.
    Conclusion: There are significant variations in long term colorectal cancer survival between different regions in England, southern England had better relative survival when compared with the northern regions. Disparities in socio-economic depravation status in different regions may be associated with worse colorectal cancer outcomes.

    Abstract Background: It is widely accepted total laparoscopic hysterectomy (TLH) and vaginal hysterectomy are less invasive procedures compared to total abdominal hysterectomy (TAH). However, rates of TAH remain unreasonably high.
    Aim: To pilot-test a model of training for practising obstetricians and gynaecologists (O&Gs) in TLH.
    Materials and methods: Training of participating O&Gs was conducted across four hospitals in Queensland, Australia, while other O&Gs were observed as contemporary controls. Type of hysterectomy, details of the surgery, including adverse events, were collected from hospital medical records.
    Results: Eleven O&Gs completed the pre-intervention and intervention training periods, and nine completed the post-intervention follow-up. TLH rates increased from 24% prior to 75% during and 68% after intervention. Overall, the uptake rate of TLH showed a two-fold increase during the intervention period (2.08, 95% CI: 1.16-8.56, P < 0.001) and a 12% increase was retained during the follow-up period (1.12, 95% CI: 0.54-4.02, P = 0.427). Pre-intervention, across all sites, 24% of hysterectomies were performed via TAH by the participating specialist trainees, which decreased to 13% during the intervention and 14% during follow-up. The rate of adverse events decreased from 13.5% at pre-intervention, to 6.4% during and 4.2% post-intervention. By comparison, no change in surgical approach or rate of adverse events was observed in the control group.
    Conclusions: The implementation of a formal and structured surgical training program teaching TLH resulted in important benefits to trainees, patients and society in the four trial hospitals.

    Abstract PURPOSE: Roots are the mean absorbing organ of plants and an important part of material circulation in ecosystems. Understanding long-term root system development and its response to soil water availability can help to elucidate carbon cycling and plant resource uptake strategies in forest plantations under climate change. METHODS: We created a soil water content (SWC) gradient in a poplar forest using irrigation. During the six-year rotation, we determined biomass allocation by dissecting 45 sample trees, and measured spatial–temporal distribution and morphology of fine roots through analysis of 3984 root samples. Observations occurred as stands developed through canopy closure and experienced increasing inter-tree competition. RESULTS: Biomass allocation initially responded positively to low SWC while rooting depth was unaffected. As stands developed, biomass allocation differences gradually disappeared, and low SWC caused deeper root distribution. Morphological responses to depth emerged after the first year. In shallow soil, specific root length and fine-root diameter were lower while root tissue density was greater than those below 50 cm depth. CONCLUSION: Soil water availability can affect biomass allocation and determine the soil layer with high exploration intensity, but both of these effects depend on stand development. During development, horizontal root system expansion takes precedence over vertical expansion. Besides, our finding implies that functional divergence of fine roots may occur gradually with stand development, with finer diameter roots in shallow soil perhaps functioning mainly for absorbing soil resources while low-density, high-diameter roots in deep soil functioning primarily for expanding the root system and exploring for limiting soil moisture resource.
