Abstract
Intervention programs are often sought to strengthen the Achilles tendon (AT) due to its high injury rate. Long rest periods between loading cycles have been found to increase collagen synthesis by tenocytes, suggesting rest duration may be important for tendon adaptation in vivo; however, exercise programs comparing long and short rest duration have not been directly compared. Fourteen adults completed a 12-week progressive training intervention; training sessions consisted of 5×10 isometric plantarflexion contractions each of 3-s duration performed at 90% of MVC three times weekly. Each leg was randomly allocated to long (LRT, 10-s rest) or short rest training (SRT, 3-s rest). We hypothesized that the leg allocated to LRT would demonstrate superior AT collagen organization compared to the leg receiving SRT, which would be related to improved biomechanical function. AT collagen organization and morphology were measured using ultrasound tissue characterization. AT properties were assessed before and after the intervention using a combination of dynamometry, ultrasound imaging, EMG, and motion capture. Contrary to our hypothesis, collagen organization did not improve following either training protocol; conversely, an unexpected decrease in echotype I proportion was seen after SRT (P<.001) but not LRT (P=.58), indicating an apparent protective effect of rest on collagen organization during isometric training. In contrast, AT adaptation was not appreciably enhanced by increasing intercycle rest duration; both protocols were equally effective at inducing significant strength gains and AT mechanical and material adaptation (P≤.001). Further research is necessary to identify optimal loading characteristics for injury prevention and rehabilitation.

Abstract
A study was conducted to investigate the influence of copper administration in ovo to chicken embryos and/or supplied in drinking water to growing chickens in the form copper nanoparticles (Cu-NP) or copper sulphate (CuSO4 ). The fertilised eggs were assigned to three groups (n = 50 per group): control (not injected), injected with 50 mg/kg Cu-NP or with 50 mg/kg CuSO4 at day 1 of incubation. Thereafter, 126 one-day-old broiler chickens were randomly assigned to seven post-hatched groups: control not injected and not provided with Cu in the drinking water, injected with 50 mg/kg Cu-NP + 20 mg/kg in water, not injected + 20 mg/kg Cu-NP in water, injected with 50 mg/kg CuSO4 + 20 mg/kg in water, not injected + 20 mg/kg CuSO4 in water, injected with 50 mg/kg Cu-NP and injected with 50 mg/kg CuSO4 . The experiment was carried out from day 1 to 35 post-hatching. The in ovo injection of Cu improved the final body weight, average daily gain and feed conversion ratio in relation to the control group. Conversely, the provision of Cu in the drinking water had less of an effect on growth performance in comparison with the injected groups. A significant improvement was shown in energy and nitrogen utilisation, being better for Cu-NP than CuSO4 . The cholesterol, urea and glucose levels in the blood were reduced by Cu-NP treatment in relation to the other groups. The relative weight of the liver was decreased, while bursa of Fabricius was increased in Cu groups in relation to the control group. Cu excretion was only reduced in chickens injected with 50 mg/kg Cu-NP + 20 mg/kg in water. The immune-related genes were not affected by the treatments. The in ovo injection of Cu-NP might improve broiler performance more efficiently than the injection of CuSO4 or the provision of Cu-NP and/or CuSO4 in drinking water.

Bovine mammary gland X chromosome inactivation. J Dairy Sci 2017; 100:5491-5500.

Abstract
X chromosome inactivation (XCI) is a process by which 1 of the 2 copies of the X chromosomes present in female mammals is inactivated. The transcriptional silencing of one X chromosome achieves dosage compensation between XX females and XY males and ensures equal expression of X-linked genes in both sexes. Although all mammals use this form of dosage compensation, the complex mechanisms that regulate XCI vary between species, tissues, and development. These mechanisms include not only varying levels of inactivation, but also the nature of inactivation, which can range from being random in nature to driven by parent of origin. To date, no data describing XCI in calves or adult cattle have been reported and we are reliant on data from mice to infer potential mechanisms and timings for this process. In the context of dairy cattle breeding and genomic prediction, the implications of X chromosome inheritance and XCI in the mammary gland are particularly important where a relatively small number of bulls pass their single X chromosome on to all of their daughters. We describe here the use of RNA-seq, whole genome sequencing and Illumina BovineHD BeadChip (Illumina, San Diego, CA) genotypes to assess XCI in lactating mammary glands of dairy cattle. At a population level, maternally and paternally inherited copies of the X chromosome are expressed equally in the lactating mammary gland consistent with random inactivation of the X chromosome. However, average expression of the paternal chromosome ranged from 10 to 90% depending on the individual animal. These results suggest that either the mammary gland arises from 1 or 2 stem cells, or a nongenetic mechanism that skews XCI exists. Although a considerable amount of future work is required to fully understand XCI in cattle, the data reported here represent an initial step in ensuring that X chromosome variation is captured and used in an appropriate manner for future genomic selection.

Detection and assessment of copy number variation using PacBio long-read and Illumina sequencing in New Zealand dairy cattle. J Dairy Sci 2017; 100:5472-5478.

Abstract
Single nucleotide polymorphisms have been the DNA variant of choice for genomic prediction, largely because of the ease of single nucleotide polymorphism genotype collection. In contrast, structural variants (SV), which include copy number variants (CNV), translocations, insertions, and inversions, have eluded easy detection and characterization, particularly in nonhuman species. However, evidence increasingly shows that SV not only contribute a substantial proportion of genetic variation but also have significant influence on phenotypes. Here we present the discovery of CNV in a prominent New Zealand dairy bull using long-read PacBio (Pacific Biosciences, Menlo Park, CA) sequencing technology and the Sniffles SV discovery tool (version 0.0.1; https://github.com/fritzsedlazeck/Sniffles). The CNV identified from long reads were compared with CNV discovered in the same bull from Illumina sequencing using CNVnator (read depth-based tool; Illumina Inc., San Diego, CA) as a means of validation. Subsequently, further validation was undertaken using whole-genome Illumina sequencing of 556 cattle representing the wider New Zealand dairy cattle population. Very limited overlap was observed in CNV discovered from the 2 sequencing platforms, in part because of the differences in size of CNV detected. Only a few CNV were therefore able to be validated using this approach. However, the ability to use CNVnator to genotype the 557 cattle for copy number across all regions identified as putative CNV allowed a genome-wide assessment of transmission level of copy number based on pedigree. The more highly transmissible a putative CNV region was observed to be, the more likely the distribution of copy number was multimodal across the 557 sequenced animals. Furthermore, visual assessment of highly transmissible CNV regions provided evidence supporting the presence of CNV across the sequenced animals. This transmission-based approach was able to confirm a subset of CNV that segregates in the New Zealand dairy cattle population. Genome-wide identification and validation of CNV is an important step toward their inclusion in genomic selection strategies.

Abstract
Abstract
BACKGROUND: Breast cancer can be broadly categorized into two groups depending on the cell type affected. Luminal-type tumors are typically estrogen receptor (ER) positive that are associated with better survival and respond to hormone therapies whereas basal-like tumors are ER negative, more aggressive, and associated with a poor prognosis. GATA3 is a transcription factor well studied for its role as a master regulator of cellular differentiation and stem cell self renewal. Loss of Gata3 in mouse mammary glands blocks luminal cell differentiation and induces growth defects, and low levels of GATA3 are associated with basal-like and metastatic human breast cancers with epithelial-to-mesenchymal transition (EMT). Importantly, luminal cells have been shown to be the origin of some basal-like breast cancers. Due to the proliferation defects caused by GATA3 deficiency, it remains elusive how loss of function of GATA3 contributes to breast cancers development and progression.
METHODS: We previously demonstrated that p18Ink4c (p18), a cell cycle inhibitor, is a downstream target of GATA3 in regulating mammary luminal cell proliferation and loss of p18 leads to luminal type tumorigenesis. To test the role of Gata3 deficiency in tumorigenesis, we generated p18-/-;Gata3+/- mice. Mammary gland development and tumorigenesis were characterized in vivo using a panel of cellular and molecular assays. Results were further confirmed in vitro with well established cell lines.
RESULTS: Loss of p18 rescued mammary growth defects caused by Gata3 heterozygosity. Gata3 heterozygosity impaired luminal, but promoted basal gene expression in mammary epithelial cells. Gata3 heterozygosity in p18 null mice accelerated spontaneous mammary tumorigenesis, reducing the average latency of tumor onset. More importantly, Gata3 heterozygosity transformed the luminal type tumors of p18 null mice into heterogeneous basal-like breast cancers with activated EMT. Conversely, reintroduction of GATA3 inhibited tumor growth and reduced expression of EMT markers in basal-like tumor xenografts. We discovered that expression of GATA3 and Vimentin, an EMT marker, is inversely related in human breast cancers.
CONCLUSION: Our data indicates that GATA3 promotes luminal but suppresses basal cell differentiation in the mammary gland and in tumor development.
Mechanisms underlying the role of GATA3 in suppressing basal-like tumor development are under investigation.BACKGROUND: Breast cancer can be broadly categorized into two groups depending on the cell type affected.

Treatment of aplastic anaemia with lower-dose anti-thymocyte globulin produces similar response rates and survival as per standard dose anti-thymocyte globulin schedules.

Abstract
BACKGROUND Aplastic anaemia (AA) is a rare acquired bone marrow failure syndrome resulting from the immune-mediated destruction of haemopoietic stem cells. For adults in whom first-line haemopoietic progenitor cell transplantation is not feasible, combination anti-thymocyte globulin (ATGAM) plus cyclosporine A is standard therapy; however, there are minimal data available regarding the optimal ATGAM dosage in terms of efficacy and survival. AIMS Our institutions have historically used different dosing protocols of ATGAM in the treatment of AA. We aimed to review the outcome of AA patients treated with these protocols and compare them to the published literature. METHODS We conducted a retrospective study of 31 adults who received first-line ATGAM for AA and compared response rates and survival between cohorts who received standard (40 mg/kg/day D1-4) versus lower-dose (15 mg/kg/day D1-5) ATGAM schedules. RESULTS There were similar rates of response (64 vs 71%, P = 1.0), relapse (33 vs 33%, P = 1.0), transformation (14 vs 24%, P = 0.66) or infection (43 vs 47%, P = 1.0), respectively, between standard and lower-dose cohorts. At a median follow up of 24 months, there was no statistical difference between standard and lower-dose cohorts in either event-free (42.2 vs 64.7%, P = 0.91) or overall survival (73.1 vs 88.2%, P = 0.75). CONCLUSION Our experience suggests that lower-dose ATGAM at 15 mg/kg/day D1-5 as treatment of AA produces similar responses and outcomes as per standard-dose ATGAM schedules. Prospective trials comparing ATGAM dose schedules in AA are warranted.

Abstract
Health is a multi-dimensional concept, capturing how people feel and function. The broad concept of Active and Healthy Ageing was proposed by the World Health Organisation (WHO) as the process of optimizing opportunities for health to enhance quality of life as people age. It applies to both individuals and population groups. A universal Active and Healthy Ageing definition is not available and it may differ depending on the purpose of the definition and/or the questions raised. While the European Innovation Partnership on Active and Healthy Ageing (EIP on AHA) has had a major impact, a definition of Active and Healthy Ageing is urgently needed. A meeting was organised in Montpellier, France, October 20-21, 2014 as the annual conference of the EIP on AHA Reference Site MACVIA-LR (Contre les Maladies Chroniques pour un Vieillissement Actif en Languedoc Roussillon) to propose an operational definition of Active and Healthy Ageing including tools that may be used for this. The current paper describes the rationale and the process by which the aims of the meeting will be reached.

Abstract
AIM To evaluate the impact of the Diabetes Inpatient Care and Education project and a comprehensive diabetes care pathway, the Diabetes Inpatient Care and Education Care Pathway, on patient outcomes and on the knowledge and confidence of trainee doctors. METHODS The effect on patient outcomes was evaluated by comparing the National Diabetes Inpatient Audit data before (2012) and after (2013) implementing the Diabetes Inpatient Care and Education project. The impact on trainee doctors was evaluated using the Modified Kirkpatrick model. Just before the project began and again 3 months later, trainee doctors were surveyed to assess their knowledge and confidence in inpatient diabetes care. RESULTS Patient harm was found to have been reduced significantly when National Diabetes Inpatient Audit data for 2012 and 2013 were compared. Severe hypoglycaemia decreased from 15.4 to 9.7%, medication errors from 56.9 to 21.1% and insulin errors from 31 to 7%. Across the 96 trainee doctors surveyed, the mean (sd) knowledge and confidence scores increased significantly (P < 0.001 for both) from 57.1 (16.8) and 61.8 (14.9) to 68.4 (13.3) and 74.3 (11.7), respectively. CONCLUSION The Diabetes Inpatient Care and Education project and the Diabetes Inpatient Care and Education Care Pathway improved patient outcomes and the knowledge and confidence of trainee doctors in this hospital. The impact of a similar project in other hospitals needs to be evaluated.

Abstract
AIM Patients with unfavourable pathology after transanal endoscopic microsurgery (TEM) should be offered completion surgery (CS) if appropriate. The aim of this retrospective cohort study was to assess the short-term outcome and long-term oncological results of CS and identify factors compromising the quality of resection specimens. METHOD Data were retrieved and analysed on patients who underwent CS from a comprehensive national TEM database (1992-2008) and the institutional prospective database from the Oxford University Hospitals (2008-2011). RESULTS There were 36 patients eligible for analysis. Postoperative complications occurred in 19 and were minor (grade I-II) in 13 and major (grade III-V) in six patients. The quality of the resected specimen was graded as good in 23 (64%), moderate in six (16.6%) and poor in seven (19.4%). Full-thickness excision by TEM (P = 0.03), an interval to CS greater than 7 weeks (P = 0.05) and distally located lesions (P = 0.04) were associated with increased risk for an inferior surgical specimen. Overall survival after CS was 91% at 1 year and 83% at 5 years. Patients with a 'good' TME specimen had significantly improved disease-free survival compared with patients with an 'inferior' specimen (100 vs 51%, P = 0.001). CONCLUSION Patients having full-thickness TEM excision, distally placed lesions and a long interval (> 7 weeks) to CS were likely to have an inferior TME specimen. The results confirm that CS after TEM does not negatively influence local recurrence and survival, but the reduced disease-free survival in patients with an inferior specimen is of concern.

Abstract
Panitumumab is a fully human monoclonal antibody targeting epidermal growth factor receptor (EGFR) approved for use in colorectal cancer (CRC). Critical information regarding biomarkers in CRC has been discovered through the investigation of panitumumab treatment. The discovery of anti-EGFR resistance in the setting of Kirsten rat sarcoma viral oncogene (KRAS) and more recently, neuroblastoma RAS viral oncogene (NRAS) mutations in CRC has changed the focus of therapy for metastatic disease to one based on the molecular characteristics of the tumor. This review will give a brief background on panitumumab and its current uses in CRC.

Abstract
The objective of this randomized controlled trial was to investigate the effect of adding either aerobic training (AT) or resistance training (RT) to a multidisciplinary teamed (MDT) educational weight management programme on the health-related fitness of morbidly obese individuals. Males (n = 9) and females (n = 24) aged between 24 and 68 years with a body mass index (BMI) of ≥40 kg m(2) (≥35 kg m(2) with comorbidities) undertaking a weight management programme were recruited (Completion: M = 8, F = 19). Participants were randomly allocated to either AT (n = 12), RT (n = 11) or CON (n = 10). AT and RT undertook three structured ∼60 min moderate intensity sessions weekly, two supervised gym-based and one structured home-based session for 12 weeks; CON undertook usual care alone. Anthropometric, psychological and functional capacity measures were obtained pre- and post-intervention. Both exercise interventions elicited improvements compared with CON in the: shuttle walk test (AT [Δ 207.0 ± 123.0 metres, 68.0%, P = 0.04], RT [Δ 165.0 ± 183.3 m, 48.8%, P = 0.06], CON [Δ -14.3 ± 38.7 m, -6.2%]), triceps skin-fold (P ≤ 0.001), self-efficacy (P = 0.005) and interest/enjoyment (P = 0.006). RT displayed additional improvements compared with CON in BMI (RT [Δ -1.02 ± 0.91 kg·m(2) , -2.5%, P = 0.033], AT [Δ -1.84 ± 2.70 kg·m(2) , -4.3%, P = 0.142], CON [Δ -0.31 ± 1.47 kg·m(2) , -0.6%]), waist circumference (P = 0.022), competence (P = 0.019), biceps skin-fold (P = 0.012) and medial calf skin-fold (P = 0.013). No significant differences were observed between exercise modalities. Regardless of exercise mode, the addition of supervised and structured exercise to a MDT weight management programme significantly improved anthropometric, functional and psychological measures in obese participants with a BMI of ≥35 kg·m(2) .

Abstract
The underdevelopment or absence of the splenic suspensary ligaments can lead to an uncommon condition termed the wandering spleen. It is usually asymptomatic but can present with an acute abdomen when associated with torsion. Most authors advocate surgical treatment. Herein, we report a case of torsion with infarction of the spleen and intestinal obstruction in a 36-year-old female patient which was successfully managed conservatively.

Abstract
This cohort study investigated the influence of psychological factors, including perception of illness, anxiety and depression on recovery and functional outcome after total knee replacement surgery. A total of 100 patients (55 male; 45 female) with a mean age of 71 (42 to 92) who underwent a primary total knee replacement for osteoarthritis were recruited into this study. In all 97 participants completed the six week and 87 the one year follow-up questionnaires. Pre-operatively patients completed the revised Illness Perception Questionnaire, Hospital Anxiety and Depression Scale and Recovery Locus of Control Scale. Function was assessed pre-operatively, at six weeks and one year using Oxford Knee Score (OKS) and the goniometer-measured range of movement (ROM). The results showed that pre-operative function had the biggest impact on post-operative outcome for ROM and OKS. In addition questionnaire variables and depression had an impact on the OKS at six weeks. Depression and anxiety were also associated with a higher (worse) knee score at one year but did not influence the ROM at either six weeks or one year. Recovery from total knee replacement can be difficult to predict. This study has identified psychological factors that play an important role in recovery from surgery and functional outcome. These should be taken into account when considering patients for total knee replacement.

Abstract
AIM To assess medical and psychological outcomes among young people with Type 1 diabetes and to compare medical outcomes with a previous audit. METHODS An observational study in two diabetes clinics for young adults (aged 16-21 years) in Sheffield, UK. Young people (n = 96: 81.4% response rate) with Type 1 diabetes (diagnosed > 6 months) completed measures of depressive symptoms, anxiety and disordered eating and consented for their medical records to be consulted. RESULTS Mean HbA1c (86 ± 23 mmol/mol; 10.0 ± 2.1%); was comparable with that reported previously and considerably higher than recommended (< 58 mmol/mol or 7.5%). Screening rates were improved and non-attendance was lower than previously reported, but levels of non-proliferative retinopathy have increased. Microvascular complications are present in 46.9% of those diagnosed more than 7 years. Elevated levels of disordered eating were reported by 35.1%. Those scoring above cut-off levels for clinical anxiety (26.6%) and depression (10.9%) are comparable with other work with young people with Type 1 diabetes. CONCLUSIONS Despite technological advances and improvements to delivery of care, HbA1c remain above recommended levels in a significant proportion of young people, many of whom already have microvascular complications. We need to learn from European centres who achieve better results, improve transition from paediatric care, integrate mental health support with diabetes care provision and take into account young people's views about clinic.
