Abstract
Chromosome X is often excluded from bovine genetic studies due to complications caused by the sex specific nature of the chromosome. As chromosome X is the second largest cattle chromosome and makes up approximately 6% of the female genome, finding ways to include chromosome X in dairy genetic studies is important. Using female animals and treating chromosome X as an autosome, we performed X chromosome inclusive genome-wide association studies in the selective breeding environment of the New Zealand dairy industry, aiming to identify chromosome X variants associated with milk production traits. We report on the findings of these genome-wide association studies and their potential effect within the dairy industry. We identify missense mutations in the MOSPD1 and CCDC160 genes that are associated with decreased milk volume and protein production and increased fat production. Both of these mutations are exonic SNP that are more prevalent in the Jersey breed than in Holstein-Friesians. Of the 2 candidates proposed it is likely that only one is causal, though we have not been able to identify which is more likely.

Abstract
PURPOSE/OBJECTIVE(S) Consistent delineation of the tumor bed (TB) after breast conserving surgery (BCS) is critical and remains a challenge with increasing prevalence of oncoplastic surgeries. Clips are generally used to help TB identification on CT-simulation but they are not well identified on MR-simulation. The aim of this study is to assess whether the use of NASHA gel with MR-simulation yields similar interobserver variability (inter-OV) compared to clips with CT-simulation. MATERIALS/METHODS This prospective single arm feasibility study included patients eligible for BCS. After lumpectomy, the surgeon placed both clips (>5) and NASHA gel drops as markers to define the TB. Patients underwent CT and MRI simulation scans. Five radiation oncologists and one radiologist delineated the TB aided by clips on CT, and gel on MRI. The observers also assessed the visibility and utility of the gel (scale from 1 to 10), as well as the cavity visualization score (CVS, scale from 1 to 5). The primary endpoint was the inter-OV of the delineated TB using the overlap difference of contours using clips and CT versus gel and MRI, with the conformity index measured according to the pair definition of the Dice Similarity Coefficient (DSC). RESULTS Of the 35 patients recruited, 30 were eligible for inter-OV analysis of TB delineation and 5 patients required further breast surgery for positive margins. One third of the eligible patients underwent an oncoplastic procedure. There were no significant differences between inter-OV of delineated TB using clips and CT versus gel and T2-weighted MRI with the mean DSC (0.60 vs 0.62, p = 0.364). The observers reported higher usefulness of gel in patients with an oncoplastic procedure than not (median US 8.2 vs 6.6, p = 0.024), and higher visibility of gel in patients who had their scans within 6 weeks than beyond post-op (median VS 8.1 vs 6.1, p = 0.013). When the CVS was higher (3-5), the median US of gel was lower (5.9 vs 7.8, p = 0.004), and the conformity index of clip and CT delineated TB was higher (median DSC 0.72 vs 0.53, p <0.001). Interestingly, a higher CVS did not lead to significantly higher conformity index of gel and T2-weighted MR delineated TB (mean DSC 0.67 vs 0.58, p = 0.073). NASHA gel injection added a median of 3 minutes to the operating theatre (OT) time and was rated as 'easy' in 89% of cases by surgeons. There were no immediate adverse events (AE) in OT, while 2 of 35 patients later experienced a grade 3 AE - hematoma which required evacuation in OT day 1 post-BCS, and infected seroma which required drainage and washout in OT 2 months post-BCS and axillary dissection. These reflect common risks with standard BCS and are not clearly attributed to gel injection alone. CONCLUSION Use of NASHA gel leads to similar inter-OV of BC TB delineation compared to >5 clips. NASHA gel is hence a reliable alternative to clips when MR-simulation is used.

Abstract
PURPOSE/OBJECTIVE(S) Nonfunctioning macroadenoma is a commonly diagnosed pituitary tumor. Resection is the favored treatment, with radiosurgery often utilized for residual or progressing disease. Long-term outcomes are established for single-session radiosurgery, but mature outcomes are lacking for multisession radiosurgery. We report our institution's 5-year efficacy and safety results for unfavorable nonfunctioning pituitary macroadenoma patients treated with marginless 5-fraction robotic radiosurgery. MATERIALS/METHODS Between 2010-2020, patients who completed marginless 5-fraction radiosurgery for the treatment of unfavorable nonfunctioning pituitary macroadenomas were included. A tumor was considered unfavorable if the gross tumor volume (GTV) was larger than 5 cc or if it closely approached a critical structure (optic apparatus, brainstem or pituitary gland). Local control was calculated using the Kaplan-Meier Method. RESULTS Twenty predominately female patients (60%), age from 21-77 (median: 53 years) were included in this study. All underwent primary resection. Indications for radiosurgery included unresectable recurrence (85%) and residual disease progression (70%). Median tumor volume was 3.4 cm3 (range: 0.3-20.8 cm3) and 40% of the tumors were suprasellar. A mean dose of 28.8 Gy (range: 25 Gy-30 Gy), was delivered to a median isodose line of 80% (range: 75%-89%). The median optic chiasm maximum point dose was 21.8 Gy (range: 12.0-25.9 Gy). Toxicity was minimal with 12 patients (40%) developing acute short-lived headaches and 1 patient (5%) developing a brief ipsilateral 6th nerve palsy. There was no radiation induced optic or pituitary dysfunction identified in this cohort. At a median follow up of 5 years local control was 95%. There was 1 in-field failure pathologically confirmed following surgery for pituitary tumor hemorrhage and 2 radiographically confirmed out-of-field failures in patients with large tumors (>20 cc). CONCLUSION The treatment of unfavorable nonfunctioning pituitary macroadenoma with marginless 5-fraction robotic radiosurgery provides excellent local control to date, with minimal toxicity. However, tumors with GTV's greater than 20 cc may require conventionally fractionated treatment with a margin to optimize local control.

Abstract
Cadmium zinc telluride (CZT) detectors enable high spatial resolution and high detection efficiency and are utilized for many gamma-ray and X-ray spectroscopy applications. In this article, we describe a stable bonding process and report on the characterization of cross-strip CZT detectors before and after bonding to flexible circuit. The bonding process utilizes gold stud bonding and polymer epoxy technique to bond the flexible circuits to two CZT crystals and form a detector module in an anode-cathode-cathode-anode (ACCA) configuration. The readout electronics is optimized in terms of shaper setting and steering electrode voltage. The average full-width half maximum (FWHM) energy resolution at 662 keV of 110 CZT crystals tested individually was 3.5% ± 0.59% and 4.75% ± 0.48% prebonded and post-bonded, respectively. No depth correction was performed in this study. The average FWHM energy resolution at 662 keV of the scaled-up system with 80 CZT crystals was 4.40% ± 0.53%, indicating the scaled-up readout electronics and stacking of the modules does not deteriorate performance. The proper shielding and grounding of the scaled-up system slightly improved the system-wide performance. The FWHM energy resolution at 511 keV of the scaled-up system was 5.85% ± 0.73%.

Abstract
BACKGROUND Post-stroke care guidelines highlight continued rehabilitation as essential; however, many stroke survivors cannot participate in outpatient rehabilitation. Technological advances in wearable sensing, treatment algorithms, and care delivery interfaces have created new opportunities for high-efficacy rehabilitation interventions to be delivered autonomously in any setting (ie, clinic, community, or home). METHODS We developed an autonomous rehabilitation system that combines the closed-loop control of music with real-time gait analysis to fully automate patient-tailored walking rehabilitation. Specifically, the mechanism-of-action of auditory-motor entrainment is applied to induce targeted changes in the post-stroke gait pattern by way of targeted changes in music. Using speed-controlled biomechanical and physiological assessments, we evaluate in 10 individuals with chronic post-stroke hemiparesis the effects of a fully-automated gait training session on gait asymmetry and the energetic cost of walking. RESULTS Post-treatment reductions in step time (Δ: -12 ± 26%, P = .027), stance time (Δ: -22 ± 10%, P = .004), and swing time (Δ: -15 ± 10%, P = .006) asymmetries were observed together with a 9 ± 5% reduction (P = .027) in the energetic cost of walking. Changes in the energetic cost of walking were highly dependent on the degree of baseline energetic impairment (r =- .90, P < .001). Among the 7 individuals with a baseline energetic cost of walking larger than the normative value of healthy older adults, a 13 ± 4% reduction was observed after training. CONCLUSIONS The closed-loop control of music can fully automate walking rehabilitation that markedly improves walking after stroke. Autonomous rehabilitation delivery systems that can safely provide high-efficacy rehabilitation in any setting have the potential to alleviate access-related care gaps and improve long-term outcomes after stroke.

Abstract
Abstract
Pseudocholinesterase is a plasma enzyme that functions to hydrolyze esters in succinylcholine, mivacurium, and ester-type local anesthetic. Pseudocholinesterase is produced in the liver and exists as an α2-globulin. Pseudocholinesterase deficiency is a rare disorder that can be acquired or inherited. Patients are asymptomatic unless given a medication that requires hydrolysis for termination of action. Pseudocholinesterase deficiency can cause delayed awakening due to prolonged action of succinylcholine. The metabolism of chloroprocaine is significantly prolonged, leading to an extended duration of nerve blockade. Cocaine’s effects can be exaggerated as cocaine is an ester-linked local anesthetic. The dibucaine number can be used to quantify pseudocholinesterase activity. Treatment is typically supportive if pseudocholinesterase deficiency is undiagnosed.

Abstract
Abstract
Addiction is characterized by psychological dependence, compulsive drug use, and other aberrant behavior. A high proportion of patients will have been or will be addicted to drugs. Complicating the anesthetic plan are the acute and chronic impact of drug use on the patient. Acute intoxication can potentiate anesthetics, leading to overdose. Chronic drug abuse can cause end-organ damage and tolerance to anesthetics and require modification of the anesthetic plan. Further complicating the anesthetic plan are the drugs used in medication assistance treatment programs for patients with addiction. The anesthesiologist should also try to limit the use of medications that may trigger an addiction relapse in a patient who is in recovery.

Abstract
Introduction
Melatonin is a neurohormone that serves a key role in human circadian physiology. It is widely used in the United States as an over-the-counter (OTC) sleep aid for managing insomnia, circadian rhythm disorders, and parasomnias. The US Food and Drug do not regulate it as a dietary supplement. However, insufficient data currently exist about formulations and overall safety for long-term usage. While serious adverse events with melatonin are rare, we describe a patient in whom clinical, laboratory, and biopsy features of autoimmune-mediated hepatitis developed in temporal association with time-release melatonin (MLTR) therapy for the treatment of dream enactment behaviors in the setting of REM-sleep behavior disorder (RBD).
Report of Cases: A 78-year-old female was referred to our clinic to manage disruptive dream enactment in the setting of RBD. The patient had been previously treated with Clonazepam, Diazepam, and Temazepam but remained refractory. Management with MLTR at 5 mg achieved clinical improvement and titration over a month up to 10 and 15 mg fully controlled dream enactment. Unfortunately, during this time, the patient developed swollen and erythematous joints and abdominal pain. Liver biopsy demonstrated lymphoplasmacytic infiltrate with rosette formation consistent with autoimmune hepatitis consistent with idiosyncratic drug-induced hepatitis associated with elevated liver function enzymes [AST 184 (H) (NL <39U/L), ALT 395 (H) (NL<56 U/L), Bilirubin, Direct= 0.3 (H) (NL<=0.2 mg/dL)]. Melatonin was discontinued achieving complete resolution of symptoms and normalization of liver function indicating its
causal association with hepatitis.
Conclusion
This unusual report of melatonin-induced autoimmune hepatitis is uncommon but points to intriguing immunostimulatory effects of melatonin. Our case highlights an important and sometimes overlooked attribute of melatonin that prescribers and patients must recognize. While melatonin is often viewed as a safe dietary supplement, its use, particularly among people with autoimmune disorders, should be documented and monitored with care.

Abstract
Introduction
Sodium oxybate is commonly used to treat narcolepsy with cataplexy. At the approved doses, the most common side effects are typically described as nausea, vomiting, dizziness, hypersomnia, urinary disturbances, and weight loss. Cases of medication-induced psychosis have been reported in the literature but remain exceedingly rare. We present a case of rapid-onset psychosis in a patient with systemic lupus erythematosus, which added complexity to the evaluation, treatment and clinical course.
Report of Cases: The patient is a 42 year old woman with a past history of fibromyalgia, lupus and a prior diagnosis of narcolepsy evaluated for daytime hypersomnia and poor night time sleep. Prior medications included sodium oxybate which was effective; and modafinil and amphetamines which created intolerable side effects. Prior sleep studies were not available and a repeat PSG/MSLT were performed. PSG did not show sleep disordered breathing or nocturnal movements and MSLT showed an average sleep latency of 5.4 minutes and 4 SOREMs. HLA DQB10602 was positive. The patient was reinitiated on sodium oxybate and titrated to 4.5g twice nightly. A few weeks later the patient developed visual hallucinations, persecutory delusions, and insomnia for 3 days. She was admitted for an evaluation to rule out lupus cerebritis, and auto-immune vs. infectious encephalitis. MRI/MRA, lumbar puncture, as well as inflammatory markers and rheumatologic and infectious work up were unrevealing. Sodium oxybate was discontinued on the day of admission and the patient’s mentation returned to baseline over the next few days. Discharge diagnosis was psychosis secondary to sodium oxybate.
Conclusion
Psychosis is an extremely rare side effect of sodium oxybate therapy among patients treated for cataplectic narcolepsy. It remains a diagnosis of exclusion, and any alternative diagnoses must be explored prior to making the diagnosis of psychosis secondary to sodium oxybate, particularly in the medically complex patient.

Abstract
Any modification to a validated assay must be evaluated in terms of the impact on the assay's performance characteristics and whether the assay remains fit for the intended purpose. The comparison is referred to as a 'method comparison', 'method comparability', 'method change', or 'comparative validation'. This review presents recommendations and examples of studies found in the current literature as a means of assessing minor modifications. In addition, the authors discuss common statistical approaches used for these comparisons.

BACKGROUND
The coronary collateral circulation is a preformed network of anastomotic connections acting as a "natural bypass" mechanism. Whilst the prevalence of collaterals varies between species, approximately 25% of patients have angiographically visible robust collaterals at the time of ST elevation myocardial infarction. While the presence of collaterals is associated with improved outcomes, the magnitude of myocardial perfusion which can be provided by the collateral circulation remains uncertain.
PURPOSE
The aim was to quantify collateral myocardial perfusion during experimental coronary balloon occlusion in patients with CAD.
METHODS
The study was approved by the local investigational review board, and all patients provided informed consent. Patients without prior infarction, bypass surgery, or angiographically visible collaterals undergoing elective percutaneous transluminal coronary angioplasty (PTCA) to a single epicardial vessel, underwent two scans with 99mTc-sestamibi myocardial perfusion single-photon emission computed tomography (SPECT). All subjects underwent at least three minutes of angiographically verified complete balloon occlusion, at which time an intravenous injection of the radiotracer was administered, followed by SPECT imaging. A second radiotracer injection followed by SPECT imaging was performed 24 hours after PTCA.
RESULTS
The study included 21 patients (median [interquartile range] age 70 [56-74] years, 52% male). The degree of diameter stenosis of treated vessels ranged from 60-99%, with successful PTCA performed with a mean 5-minute balloon occlusion time, resulting in ≤20% residual stenosis in all cases. The vessels undergoing PTCA were 6 in the LAD, 5 in the LCx, and 10 in the RCA. For the cohort, the size of the perfusion defect was 16 [8-30]% of the LV and the collateral perfusion at rest within the perfusion defect was 64 [58-68]% of normal perfusion within that region. Collateral perfusion was negatively correlated with perfusion defect size (R2 = 0.85, p < 0.001), but did not differ by sex (p = 0.27) or age (p = 0.58). CONCLUSIONS: This is the first study to describe the magnitude of microvascular collateral perfusion in CAD. On average, despite coronary occlusion and an absence of angiographically visible collateral vessels, collaterals provide approximately 60% of the perfusion that reaches the jeopardized myocardium during coronary occlusion. This magnitude of collateral perfusion is much higher than previously speculated. A previous study using microspheres in dogs found that collateral perfusion in the setting of an occluded vessel was 6% of normal. By comparison, the current study found ten times greater collateral perfusion in patients with CAD.

Abstract
A robust impurity detection and tracking code, able to generate large sets of dust tracks from tokamak camera footage, is presented. This machine learning-based code is tested with cameras from the Joint European Torus, Doublet-III-D, and Magnum-PSI and is able to generate dust tracks with a 65-100% classification accuracy. Moreover, the number dust particles detected from a single camera shot can be up to the order of 1000. Several areas of improvement for the code are highlighted, such as generating more significant training data sets and accounting for selection biases. Although the code is tested with dust in single two-dimensional camera views, it could easily be applied to multiple-camera stereoscopic reconstruction or nondust impurities.

Abstract
BACKGROUND The rhythm of music can entrain neurons in motor cortex by way of direct connections between auditory and motor brain regions. OBJECTIVE We sought to automate an individualized and progressive music-based, walking rehabilitation program using real-time sensor data in combination with decision algorithms. METHODS A music-based digital therapeutic was developed to maintain high sound quality while modulating, in real-time, the tempo (ie, beats per minute, or bpm) of music based on a user's ability to entrain to the tempo and progress to faster walking cadences in-sync with the progression of the tempo. Eleven individuals with chronic hemiparesis completed one automated 30-minute training visit. Seven returned for 2 additional visits. Safety, feasibility, and rehabilitative potential (ie, changes in walking speed relative to clinically meaningful change scores) were evaluated. RESULTS A single, fully automated training visit resulted in increased usual (∆ 0.085 ± 0.027 m/s, P = .011) and fast (∆ 0.093 ± 0.032 m/s, P = .016) walking speeds. The 7 participants who completed additional training visits increased their usual walking speed by 0.12 ± 0.03 m/s after only 3 days of training. Changes in walking speed were highly related to changes in walking cadence (R2 > 0.70). No trips or falls were noted during training, all users reported that the device helped them walk faster, and 70% indicated that they would use it most or all of the time at home. CONCLUSIONS In this proof-of-concept study, we show that a sensor-automated, progressive, and individualized rhythmic locomotor training program can be implemented safely and effectively to train walking speed after stroke. Music-based digital therapeutics have the potential to facilitate salient, community-based rehabilitation.

Abstract
OBJECTIVES To describe the history, clinicopathological abnormalities, diagnostic imaging findings, lymph node cytological/histological appearance, treatment and outcome of English springer spaniels diagnosed with idiopathic pyogranulomatous lymphadenitis. MATERIALS AND METHODS In this retrospective UK-based multicentre study, 64 dogs were recruited from 10 referral centres, 32 first-opinion practices and three histopathology/cytology laboratories, between 2010 and 2016. RESULTS The median age at presentation was 6 years (range: 0.17 to 11.75). Neutered females were frequently affected. Pyrexia (83.8%), peripheral lymphadenomegaly (78.4%), dermatological lesions (72.9%), lethargy (67.6%), hyporexia (54%), diarrhoea (29.7%), coughing (24.3%), epistaxis, sneezing or nasal discharge (21.6%), ocular signs (21.6%) and vomiting (16.2%) were reported in dogs for which the history and physical examination records were available. Popliteal (45.3%), superficial cervical (35.9%) and submandibular (37.5%) lymphadenomegaly were frequently reported. Haematology and serum biochemistry revealed non-specific changes. When undertaken, testing for infectious diseases was negative in all cases. Lymph node cytology, histopathology or both demonstrated mixed inflammatory (27%), pyogranulomatous (24%), neutrophilic (20%) or granulomatous (11%) lymphadenitis. Treatment details were available for 38 dogs, with 34 receiving prednisolone for a median duration of 15 weeks (range: 1 to 28 weeks). A good to excellent clinical response was reported in all but one case. Ten dogs relapsed after discontinuing prednisolone. CLINICAL SIGNIFICANCE Idiopathic pyogranulomatous lymphadenitis should be considered as a differential diagnosis for lymphadenopathy and pyrexia in English springer spaniels. The characteristics of the disease, absence of identifiable infectious aetiology and response to glucocorticoid therapy suggest an immune-mediated aetiology.

Abstract
OBJECTIVE We tested the ability of a type 1 diabetes (T1D) genetic risk score (GRS) to predict progression of islet autoimmunity and T1D in at-risk individuals. RESEARCH DESIGN AND METHODS We studied the 1,244 TrialNet Pathway to Prevention study participants (T1D patients' relatives without diabetes and with one or more positive autoantibodies) who were genotyped with Illumina ImmunoChip (median [range] age at initial autoantibody determination 11.1 years [1.2-51.8], 48% male, 80.5% non-Hispanic white, median follow-up 5.4 years). Of 291 participants with a single positive autoantibody at screening, 157 converted to multiple autoantibody positivity and 55 developed diabetes. Of 953 participants with multiple positive autoantibodies at screening, 419 developed diabetes. We calculated the T1D GRS from 30 T1D-associated single nucleotide polymorphisms. We used multivariable Cox regression models, time-dependent receiver operating characteristic curves, and area under the curve (AUC) measures to evaluate prognostic utility of T1D GRS, age, sex, Diabetes Prevention Trial-Type 1 (DPT-1) Risk Score, positive autoantibody number or type, HLA DR3/DR4-DQ8 status, and race/ethnicity. We used recursive partitioning analyses to identify cut points in continuous variables. RESULTS Higher T1D GRS significantly increased the rate of progression to T1D adjusting for DPT-1 Risk Score, age, number of positive autoantibodies, sex, and ethnicity (hazard ratio [HR] 1.29 for a 0.05 increase, 95% CI 1.06-1.6; P = 0.011). Progression to T1D was best predicted by a combined model with GRS, number of positive autoantibodies, DPT-1 Risk Score, and age (7-year time-integrated AUC = 0.79, 5-year AUC = 0.73). Higher GRS was significantly associated with increased progression rate from single to multiple positive autoantibodies after adjusting for age, autoantibody type, ethnicity, and sex (HR 2.27 for GRS >0.295, 95% CI 1.47-3.51; P = 0.0002). CONCLUSIONS The T1D GRS independently predicts progression to T1D and improves prediction along T1D stages in autoantibody-positive relatives.

Abstract
Current clinically-tested nicotine vaccines have yet shown enhanced smoking cessation efficacy due to their low immunogenicity. Achieving a sufficiently high immunogenicity is a necessity for establishing a clinically-viable nicotine vaccine. This study aims to facilitate the immunogenicity of a hybrid nanoparticle-based nicotine vaccine by rationally incorporating toll-like receptor (TLR)-based adjuvants, including monophosphoryl lipid A (MPLA), Resiquimod (R848), CpG oligodeoxynucleotide 1826 (CpG ODN 1826), and their combinations. The nanoparticle-delivered model adjuvant was found to be taken up more efficiently by dendritic cells than the free counterpart. Nanovaccine particles were transported to endosomal compartments upon cellular internalization. The incorporation of single or dual TLR adjuvants not only considerably increased total anti-nicotine IgG titers but also significantly affected IgG subtype distribution in mice. Particularly, the nanovaccines carrying MPLA+R848 or MPLA+ODN 1826 generated a much higher anti-nicotine antibody titer than those carrying none or one adjuvant. Meanwhile, the anti-nicotine antibody elicited by the nanovaccine adjuvanted with MPLA+R848 had a significantly higher affinity than that elicited by the nanovaccine carrying MPLA+ODN 1826. Moreover, the incorporation of all the selected TLR adjuvants (except MPLA) reduced the brain nicotine levels in mice after nicotine challenge. Particularly, the nanovaccine with MPLA+R848 exhibited the best ability to reduce the level of nicotine entering the brain. Collectively, rational incorporation of TLR adjuvants could enhance the immunological efficacy of the hybrid nanoparticle-based nicotine vaccine, making it a promising next-generation immunotherapeutic candidate for treating nicotine addiction.

Abstract
Surveillance of emerging viral variants is critical to ensuring that blood screening and diagnostic tests detect all infections regardless of strain or geographic location. In this study, we conducted serological and molecular surveillance to monitor the prevalence and diversity of HIV, HBV, and HTLV in South Cameroon. The prevalence of HIV was 8.53%, HBV was 10.45%, and HTLV was 1.04% amongst study participants. Molecular characterization of 555 HIV-1 specimens identified incredible diversity, including 7 subtypes, 12 CRFs, 6 unclassified, 24 Group O and 2 Group N infections. Amongst 401 HBV sequences were found a rare HBV AE recombinant and two emerging sub-genotype A strains. In addition to HTLV-1 and HTLV-2 strains, sequencing confirmed the fifth known HTLV-3 infection to date. Continued HIV/HBV/HTLV surveillance and vigilance for newly emerging strains in South Cameroon will be essential to ensure diagnostic tests and research stay a step ahead of these rapidly evolving viruses.

Abstract
OBJECTIVE For some esthetic clinical situations, it is necessary to finish crown margins on direct restorative materials to preserve tissue integrity, bonding integrity, and biological width. The purpose of this research was to investigate microleakage at the interface between bonded lithium disilicate crowns and various direct restorative materials in a class III and class V position. METHODS AND MATERIALS Class III or class V restorations were prepared on one side of extracted incisors with either Tetric EvoCeram, Tetric Evoceram Bulk, Fuji II LC, or Tetric Evoflow. The teeth were prepared for and received a lithium disilicate crown. After load fatiguing, the specimens were thermo-cycled with a fuchsin dye and sectioned. The depth and area of dye penetration were measured with a dimensional grid in micrometers using stereomicroscopy and reported as mean dye depth and area (μm) ± SD. The comparison of multiple categorical independent variables with ratio scale dependent variables was evaluated with an analysis of variance and Tukey's post hoc analysis. RESULTS A statistically significant higher dye penetration was noted for all treatment groups compared with the positive control (side opposite the restoration after sagittal sectioning was used as positive control) regardless of material or placement area (p<0.05). In comparing treatment groups, the Tetric EvoFlow experienced a statistically higher dye penetration than did the other treatment groups regardless of material or placement area (p<0.05). There was no statistically significant difference between the Tetric EvoCeram, Tetric Evoceram Bulk, and Fuji II LC materials regardless of placement area (p>0.05). CONCLUSIONS Within the limitations of this study, it can be concluded that flowable composite materials as finish lines that interact with resin cements could lead to exacerbated interfacial degradation. Finishing lithium disilicate all-ceramic crowns on flowable resin composite materials in the esthetic zone should be used with caution. If necessary, finishing lithium disilicate all-ceramic crowns on nanofilled resin composite or resin-modified glass ionomer materials seems to provide the least dye penetration depth and area.

Abstract
Background Bacterial cholangitis and cholecystitis are rarely reported, poorly characterized diseases in the dog. Objectives To characterize the clinical features of these conditions. Animals Twenty‐seven client‐owned dogs with bacterial cholangitis, cholecystitis, or both. Methods Multicenter, retrospective cases series of dogs with bacterial cholangitis, cholecystitis, or both, presenting January 2000 to June 2011 to 4 Veterinary Schools in Ireland/United Kingdom. Interrogation of hospital databases identified all cases with the inclusion criteria; histopathologically confirmed cholangitis or cholecystitis and bile culture/cytology results supporting a bacterial etiology. Results Twenty‐seven dogs met the inclusion criteria with approximately 460 hepatitis cases documented over the same study period. Typical clinical pathology findings were increases in liver enzyme activities (25/26), hyperbilirubinemia (20/26), and an inflammatory leukogram (21/24). Ultrasound findings, although nonspecific, aided decision‐making in 25/26 cases. The most frequent hepatobiliary bacterial isolates were Escherichia coli (n = 17; 16 cases), Enterococcus spp. (n = 8; 6 cases), and Clostridium spp. (n = 5; 5 cases). Antimicrobial resistance was an important feature of aerobic isolates; 10/16 E. coli isolates resistant to 3 or more antimicrobial classes. Biliary tract rupture complicated nearly one third of cases, associated with significant mortality (4/8). Discharged dogs had a guarded to fair prognosis; 17/18 alive at 2 months, although 5/10 re‐evaluated had persistent liver enzyme elevation 2–12 months later. Conclusion and Clinical Significance Bacterial cholangitis and cholecystitis occur more frequently than suggested by current literature and should be considered in dogs presenting with jaundice and fever, abdominal pain, or an inflammatory leukogram or with ultrasonographic evidence of gallbladder abnormalities.

Abstract
Abstract
The ability of cancer cells to produce large amounts of lactate through aerobic glycosis (Warburg effect) is coupled to high rates of glucose uptake. Enhanced glucose uptake and glycolysis are closely correlated to increased breast tumor aggressiveness and poor prognosis. However, despite the importance of glucose uptake in supplying energy and preventing apoptosis of cancer cells, the majority of current efforts in searching for therapeutic agents targeting glucose metabolism have been aimed at modulating activities of different metabolic enzymes that are involved in glycolysis. Very limited studies have been done in developing novel therapeutic agents against glucose uptake in breast cancer cells.
Ataxia-telangiectasia (A-T) is a monogenic, autosomal recessive disorder characterized by cerebellar ataxia and oculocutaneous telangiectasias. The gene mutated in this disease, ATM (A-T, mutated), encodes a 370-kDa protein kinase. Although ATM is traditionally considered to be a nuclear protein that functions as a signal transducer in the cellular response to DNA damage, it is now known that ATM is also present in the cytoplasm and has important cytoplasmic functions. We previously discovered that ATM activates Akt, a main regulator of glucose uptake, by stimulating its phosphorylation at Ser473 following insulin treatment. We also found that ATM participates in insulin-mediated glucose uptake in muscle cells, and KU-55933, a specific inhibitor of ATM, strongly inhibits this process.
Recently, we found that KU-55933 inhibits cell proliferation by inducing apoptosis in MDA-MB-231, a triple-negative breast cancer cell line. We have also found that KU-55933 inhibits migration of MDA-MB-231 by a cell invasion assay. Furthermore, we found that these cancer cells exhibit enhanced glucose uptake in response to insulin and the addition of KU-55933 leads to a dramatic reduction of insulin-mediated glucose uptake in these cells. To further test whether KU-55933's ability to induce apoptosis is linked to its inhibition of glucose uptake, we performed a cell death ELISA assay in MDA-MB-231 cells treated with KU-55933 and different concentrations of glucose. Our results show that KU-55933 induces apoptosis of MDA-MB-231 cells, resulting in a similar degree of cell death as glucose starvation, while cells treated with glucose in conjunction with KU-55933 have decreased apoptosis. Moreover, we performed a cell migration assay and found that KU-55933 strongly inhibits the migration of MDA-MB-231 cells (similar to that caused by glucose starvation), which is almost fully rescued by the extra glucose supplemented in the cell culture medium. We have also established a positional isotope labeling-based targeted metabolomics method that can directly measure the conversion from glucose to lactate through glycolysis in cancer cells. Our results show strong production of lactate from glucose in MDA-MB-231 cells even under normal aerobic growth conditions, and KU-55933 strongly inhibits this process. Our findings may lead to the development of KU-55933 and its analogs as a new generation of therapeutic agents against aggressive breast cancer.

Abstract
Sedimentary basins around the world considered suitable for carbon storage usually contain other natural resources such as petroleum, coal, geothermal energy and groundwater. Storing carbon dioxide in geological formations in the basins adds to the competition for access to the subsurface and the use of pore space where other resource-based industries also operate. Managing potential impacts that industrial-scale injection of carbon dioxide may have on other resource development must be focused to prevent potential conflicts and enhance synergies where possible. Such a sustainable coexistence of various resource developments can be accomplished by implementing a Framework for Basin Resource Management strategy (FBRM). The FBRM strategy utilizes the concept of an Area of Review (AOR) for guiding development and regulation of CO2 geological storage projects and for assessing their potential impact on other resources. The AOR is determined by the expected physical distribution of the CO2 plume in the subsurface and the modelled extent of reservoir pressure increase resulting from the injection of the CO2. This information is used to define the region to be characterised and monitored for a CO2 injection project. The geological characterisation and risk- and performance-based monitoring will be most comprehensive within the region of the reservoir containing the carbon dioxide plume and should consider geological features and wells continuously above the plume through to its surface projection; this region defines where increases in reservoir pressure will be greatest and where potential for unplanned migration of carbon dioxide is highest. Beyond the expanse of the carbon dioxide plume, geological characterisation and monitoring should focus only on identified features that could be a potential migration conduit for either formation water or carbon dioxide.

Abstract
Introduction To avoid the need for reconstitution required by lyophilized palivizumab, a liquid formulation was developed. This study assessed the safety and antidrug antibodies (ADA) of the liquid formulation of palivizumab compared with the lyophilized formulation. Methods This phase 4, randomized, double-blind, multicenter study included children with chronic lung disease of prematurity who were ≤24 months of age and children born prematurely with a gestational age of ≤35 weeks who were ≤6 months of age at randomization. Subjects were randomized 1:1 to 15 mg/kg of either liquid or lyophilized palivizumab administered via intramuscular injection every 30 days for a total of 5 injections. Safety was assessed based on serious adverse events (SAEs). ADA to palivizumab was assessed using blood collected at baseline and at a time point between study days 240 and 300. Results A total of 413 subjects were included in the analyses. The incidence of SAEs reported was 8.5% with liquid palivizumab and 5.9% with lyophilized palivizumab; none were deemed drug-related. The reported SAEs were consistent with expected conditions in this pediatric age group; there was no increase in respiratory syncytial virus (RSV) disease with liquid palivizumab. At study days 240–300, antipalivizumab antibodies were detected in none of the subjects in the liquid palivizumab group and in 1 subject in the lyophilized group. The true ADA percent positive, based on the upper limit of the 95% confidence interval (CI), was <1.5% for both treatments combined. Conclusion The frequency of detection of ADAs was low. The true ADA percent positive for both treatment groups combined based on the upper limit of the 95% CI was <1.5%. The type and frequency of SAEs reported were as expected, and there was no evidence of an increase in RSV disease with liquid palivizumab.

Abstract
Behavioral Momentum Theory (BMT) has inspired animal models of treatment relapse. We translated the models of reinstatement and resurgence into clinical procedures to test whether relapse tests would replicate behavior pattern found in basic research. Following multiple schedule baseline reinforcement of a 16-year-old male's problem behavior at equal rates by two therapists, treatment was introduced using a variable-interval, variable-time (VI VT) schedule arrangement with therapists delivering reinforcers at different rates. Despite the differing rates of VI VT reinforcers, the treatment produced comparable reductions in problem behavior. Following successful treatment, the two therapists discontinued treatment and resumed reinforcement of problem behavior at equal rates that constituted a reinstatement of baseline conditions. As predicted by BMT, reinstatement resulted in an immediate return of high rates of problem behavior but was 2.6 times higher for the therapist using the higher rate VI VT treatment. A second treatment phase was implemented followed by a test of resurgence in a single extended extinction session conducted separately for each therapist. The unequal VI VT treatment rates by therapists resulted in 2.1 times greater responding in the resurgence test for the therapist who implemented the higher rate VI VT procedure. These results are consistent with basic research studies and BMT.
