Selection for body weight at eight weeks of age in dwarf and normal meat-type chickens originating from a common control population background.

A study was conducted to evaluate responses to selection for 8-week body weight in normal and dwarf meat-type broiler lines originating from the same nonselected randombred population. Following three generations of selection, normal and dwarf dams were mated to males from a commercial broiler stock to compare strain cross performance of progeny from the two dam groups. The mean realized heritabilities across four generations for 8-week body weight, estimated by dividing the cumulative responses by the cumulative selection differentials, were . 69 for normal lines and . 59 for dwarf lines. Realized estimates from regression of population means on cumulative selection differentials were . 78 +/- . 10 and . 74 +/- . 02 for normal lines and . 70 +/- . 14 and . 59 +/- . 19 for dwarf lines. Although these estimates were not significantly different, realized heritabilities were consistently greater in normal than in dwarf lines across generations. The smaller heritability estimates observed in dwarf lines were compensated for by larger selection intensities (i), which resulted in similar selection responses in 8-week body weight for normal and dwarf genotypes. The fertility of normal and dwarf females mated to commercial broiler males was identical. However, the hatchability of fertile eggs was approximately 10% higher for dwarfs than for normal females. Body weights (8-week) of male progeny from dwarf dams mated to commercial males were 3% smaller than comparable males from normal dams. There were no differences between 8-week body weights of female progeny from normal and dwarf dams mated to commercial males.
Impact of 9/11-related chronic conditions and PTSD comorbidity on early retirement and job loss among World Trade Center disaster rescue and recovery workers.

BACKGROUND The economic impact of the 9/11 terrorist attacks has rarely been studied. We examined the association between 9/11-related chronic health conditions with or without post-traumatic stress disorder (PTSD) and one important aspect of the economic impact, retirement, and job loss before age 60. METHODS A total of 7,662 workers who participated in the World Trade Center Health Registry surveys were studied. Logistic regression models examined the association of 9/11-related health and labor force exit. RESULTS Workers with chronic conditions were more likely to experience early retirement and job loss, and the association was stronger in the presence of PTSD comorbidity: the odds ratios for reporting early retirement or job loss were increased considerably when chronic conditions were comorbid with PTSD. CONCLUSIONS Disaster-related health burden directly impacts premature labor force exit and income. Future evaluation of disaster outcome should include its long-term impact on labor force. Am. J.

Alternative Oxidase Dependent Respiration Leads to an Increased Mitochondrial Content in Two Long-Lived Mutants of the Ageing Model Podospora anserina

The retrograde response constitutes an important signalling pathway from mitochondria to the nucleus which induces several genes to allow compensation of mitochondrial impairments. In the filamentous ascomycete Podospora anserina, an example for such a response is the induction of a nuclear-encoded and iron-dependent alternative oxidase (AOX) occurring when cytochrome-c oxidase (COX) dependent respiration is affected. Several long-lived mutants are known which predominantly or exclusively respire via AOX. Here we show that two AOX-utilising mutants, grisea and PaCox17::ble, are able to compensate partially for lowered OXPHOS efficiency resulting from AOX-dependent respiration by increasing mitochondrial content. At the physiological level this is demonstrated by an elevated oxygen consumption and increased heat production. However, in the two mutants, ATP levels do not reach WT levels. Interestingly, mutant PaCox17::ble is characterized by a highly increased release of the reactive oxygen species (ROS) hydrogen peroxide. Both grisea and PaCox17::ble contain elevated levels of mitochondrial proteins involved in quality control, i. e. LON protease and the molecular chaperone HSP60. Taken together, our work demonstrates that AOX-dependent respiration in two mutants of the ageing model P. anserina is linked to a novel mechanism involved in the retrograde response pathway, mitochondrial biogenesis, which might also play an important role for cellular maintenance in other organisms.
Gender Differences in Equity Crowdfunding

Online peer-to-peer investment platforms are increasingly popular venues for entrepreneurs and investors to engage in financial transactions without the involvement of banks and loan managers. Despite their purported transparency and lack of bias, it is unclear whether social inequalities present in traditional capital markets transfer to these platforms as well, impeding their hoped revolutionary potential. In this paper we analyze nearly four years' worth of data from one of the leading UK-based equity crowdfunding platforms. Specifically, we investigate gender-related differences in patterns of entrepreneurship, investment, and success. In agreement with offline trends, men have more activity on the platform. Yet, women entrepreneurs benefit of higher success rates in fund-raising, a finding that mimics trends seen on some rewards-based crowdfunding platforms. Surprisingly, we also find that female investors tend to choose campaigns that have lower success rates. Our findings contribute to a better understanding of gender-related discrepancies in success on the online capital market and point to differences in activity that are key factors in the apparent patterns of gender inequality.
A Comparison of the Safety and Efficacy of HX575 (Epoetin Alfa Proposed Biosimilar) with Epoetin Alfa in Patients with End-Stage Renal Disease

Background: HX575 (biosimilar epoetin alfa) was approved in Europe in 2007 for the treatment of chronic kidney disease (CKD)-related anemia. This study assessed the clinical equivalence of HX575 with the US-licensed reference epoetin alfa (Epogen®/Procrit®, Amgen/Janssen) following subcutaneous (SC) administration in dialysis patients with CKD-related anemia. Methods: This randomized, double-blind, parallel-group, multicenter study (NCT01693029) was conducted at 49 US clinical sites. Eligible patients were aged ≥18 years, had end-stage renal disease, were on hemodialysis or peritoneal dialysis for ≥6 months (or ≥12 months in the case of a failed kidney transplant), and were receiving treatment with stable SC doses of epoetin alfa. Eligible patients also had mean hemoglobin (Hb) concentration between 9.0 and 11.5 g/dL during the screening period. The primary endpoint was the mean absolute change in Hb concentration between the screening/baseline period (week-4 to week-1) and the evaluation period (weeks 21 to 28). Results: Hb values at the end of the evaluation period and the Hb change from baseline to evaluation period were similar between treatment groups. The estimated difference between groups in mean absolute change in Hb concentration was –0.093 g/dL, with 90% CI (–0.23 to 0.04) entirely within the pre-specified equivalence limits (–0.5 to 0.5 g/dL). The safety profile of each medicine was similar and as expected in dialysis patients, and neither method of treatment led to the development of neutralizing, clinically relevant antibodies. Conclusions: SC HX575 in dialysis patients with renal anemia was therapeutically equivalent to the reference medicine in terms of maintaining stable Hb levels and safety.
Native bees buffer the negative impact of climate warming on honey bee pollination of watermelon crops

If climate change affects pollinator‐dependent crop production, this will have important implications for global food security because insect pollinators contribute to production for 75% of the leading global food crops. We investigate whether climate warming could result in indirect impacts upon crop pollination services via an overlooked mechanism, namely temperature‐induced shifts in the diurnal activity patterns of pollinators. Using a large data set on bee pollination of watermelon crops, we predict how pollination services might change under various climate change scenarios. Our results show that under the most extreme IPCC scenario (A1F1), pollination services by managed honey bees are expected to decline by 14.5%, whereas pollination services provided by most native, wild taxa are predicted to increase, resulting in an estimated aggregate change in pollination services of +4.5% by 2099. We demonstrate the importance of native biodiversity in buffering the impacts of climate change, because crop pollination services would decline more steeply without the native, wild pollinators. More generally, our study provides an important example of how biodiversity can stabilize ecosystem services against environmental change.
Green Synthesis of Metallic and Carbon Nanostructures

The technological and biomedical applications of low toxicity and eco-friendly organic compounds are nowadays increasingly attracting the attention of researchers in nano science, who are aiming for more biocompatible and nanostructured systems for their application in antineoplastic therapies. This study presents the significance of “green components” in the production of graphene, metallic, and semiconductor nanoparticles, due to their antioxidant and antitumor properties. The formation of nanostructures is caused during green synthesis methods by organic molecules or carboxylic acid groups present in some plant extracts; for this reason, we include here a recapitulation and analysis of the role of carboxylic acids in those systems (organic). Furthermore, we pro- pose the use of the extract from Opuntia ficus-indica cladodes to obtain metallic and carbon nanostructures, as an alternative biosynthesis method for the development of future nanobiotechnological applications.
A pilot study investigating changes in neural processing after mindfulness training in elite athletes

The ability to pay close attention to the present moment can be a crucial factor for performing well in a competitive situation. Training mindfulness is one approach to potentially improve elite athletes’ ability to focus their attention on the present moment. However, virtually nothing is known about whether these types of interventions alter neural systems that are important for optimal performance. This pilot study examined whether an intervention aimed at improving mindfulness [Mindful Performance Enhancement, Awareness and Knowledge (mPEAK)] changes neural activation patterns during an interoceptive challenge. Participants completed a task involving anticipation and experience of loaded breathing during functional magnetic resonance imaging recording. There were five main results following mPEAK training: (1) elite athletes self-reported higher levels of interoceptive awareness and mindfulness and lower levels of alexithymia; (2) greater insula and anterior cingulate cortex (ACC) activation during anticipation and post-breathing load conditions; (3) increased ACC activation during the anticipation condition was associated with increased scores on the describing subscale of the Five Facet Mindfulness Questionnaire; (4) increased insula activation during the post-load condition was associated with decreases in the Toronto Alexithymia Scale identifying feelings subscale; (5) decreased resting state functional connectivity between the PCC and the right medial frontal cortex and the ACC. Taken together, this pilot study suggests that mPEAK training may lead to increased attention to bodily signals and greater neural processing during the anticipation and recovery from interoceptive perturbations. This association between attention to and processing of interoceptive afferents may result in greater adaptation during stressful situations in elite athletes.
Adamts5 (aggrecanase‐2) is widely expressed in the mouse musculoskeletal system and is induced in specific regions of knee joint explants by inflammatory cytokines

ADAMTS5 (aggrecanase‐2) is an extracellular matrix‐degrading protease implicated in cartilage destruction in arthritis. Our goals were to determine expression sites of Adamts5 in the murine musculoskeletal system and in an ex vivo joint inflammation model. In mice with an intragenic LacZ reporter controlled by the Adamts5 promoter, β‐galactosidase staining was used to identify Adamts5 expressing cells. Mice expressing one wild‐type Adamts5 allele were used to determine distribution of Adamts5 mRNA, cleaved aggrecan and versican, and the ADAMTS5 activating enzymes furin and PACE4. Quantitative RT‐PCR and immunoblotting were used to validate the immunohistochemistry results. Adamts5 was expressed in mouse synovium, tenosynovium, bone marrow sinusoids, tendons, ligaments, ligament insertions, periosteal cells, and bone vasculature. In knee joint explants treated with IL‐1α and TNFα, Adamts5 expression was induced in tenocytes, synovium, and in patellar, but not femoral or tibial articular cartilage. In contrast, increased proteoglycan breakdown in tibial and femoral articular cartilage was associated with increased immunohistochemical staining of PACE4 and furin. These studies identify diverse cell types in the musculoskeletal system that express Adamts5. They also suggest that Adamts5 induction in joint components other than cartilage, and its post‐translational activation by PACE4 and/or furin may be important in the pathophysiology of arthritis. © 2011 Orthopaedic Research Society Published by Wiley Periodicals, Inc.

Burnout and self-reported suboptimal patient care amongst health care workers providing HIV care in Malawi

Background The well-documented shortages of health care workers (HCWs) in sub-Saharan Africa are further intensified by the increased human resource needs of expanding HIV treatment programs. Burnout is a syndrome of emotional exhaustion (EE), depersonalization (DP), and a sense of low personal accomplishment (PA). HCWs’ burnout can negatively impact the delivery of health services. Our main objective was to examine the prevalence of burnout amongst HCWs in Malawi and explore its relationship to self-reported suboptimal patient care. Methods A cross-sectional study among HCWs providing HIV care in 89 facilities, across eight districts in Malawi was conducted. Burnout was measured using the Maslach Burnout Inventory defined as scores in the mid-high range on the EE or DP subscales. Nine questions adapted for this study assessed self-reported suboptimal patient care. Surveys were administered anonymously and included socio-demographic and work-related questions. Validated questionnaires assessed depression and at-risk alcohol use. Chi-square test or two-sample t-test was used to explore associations between variables and self-reported suboptimal patient care. Bivariate analyses identified candidate variables (p < 0.2). Final regression models included variables with significant main effects. Results Of 520 HCWs, 62% met criteria for burnout. In the three dimensions of burnout, 55% reported moderate-high EE, 31% moderate-high DP, and 46% low-moderate PA. The majority (89%) reported engaging in suboptimal patient care/attitudes including making mistakes in treatment not due to lack of knowledge/experience (52%), shouting at patients (45%), and not performing diagnostic tests due to a desire to finish quickly (35%). In multivariate analysis, only burnout remained associated with self-reported suboptimal patient care (OR 3.22, [CI 2.11 to 4.90]; p<0.0001). Conclusion Burnout was common among HCWs providing HIV care and was associated with self-reported suboptimal patient care practices/attitudes. Research is needed to understand factors that contribute to and protect against burnout and that inform the development of strategies to reduce burnout.
Necrotising Scleritis and Peripheral Ulcerative Keratitis Associated with Rheumatoid Arthritis Treated with Rituximab

Abstract Background Rheumatoid arthritis is a chronic and common inflammatory autoimmune disease. This primarily involves the synovia of the joints, but can cause many extra-articular manifestations as well, including peripheral ulcerative keratitis (PUK) and necrotising scleritis. These are often a threat to vision; they significantly compromise not only the eyeʼs structural integrity but are also important for prognosis and need urgent management. History and signs Three cases of peripheral ulcerative keratitis associated with rheumatoid arthritis were recorded in the electronic databank of the Jules Gonin Uveitis Clinic, two with necrotising scleritis and peripheral ulcerative keratitis and one with only peripheral ulcerative keratitis. They were all followed at Jules Gonin Eye Hospital (Lausanne, Switzerland), conjointly with the Department of Rheumatology at the Centre Hospitalier Universitaire Vaudois (Lausanne, Switzerland). Therapy and Outcome Good initial therapeutic response was observed in the two patients who received rituximab therapy. The patient who received only high dose corticosteroid developed massive colon perforation as well as acute renal insufficiency a few days after her ocular event. Conclusion From our limited number of patients, we found that the two patients who received the induction therapy with rituximab were stabilised from an ocular standpoint; however, rituximab had to be switched to other molecules, either due to other systemic symptoms from the disease itself or due to adverse effect of this treatment. This contributes to the increasing number of reports that rituximab can be an effective treatment for refractory ocular complications of rheumatoid arthritis (RA), at least as an induction therapy.
Chronic pain and impaired glial glutamate transporter function in lupus‐prone mice are ameliorated by blocking macrophage colony‐stimulating factor‐1 receptors

Systemic lupus erythematosus (SLE) is a multi‐organ disease of unknown etiology in which the normal immune responses are directed against the body's own healthy tissues. Patients with SLE often suffer from chronic pain. Currently, no animal studies have been reported about the mechanisms underlying pain in SLE. In this study, the development of chronic pain in MRL lupus‐prone (MRL/lpr) mice, a well‐established lupus mouse model, was characterized for the first time. We found that female MRL/lpr mice developed thermal hyperalgesia at the age of 13 weeks, and mechanical allodynia at the age of 16 weeks. MRL/lpr mice with chronic pain had activation of microglia and astrocytes, over‐expression of macrophage colony‐stimulating factor‐1 (CSF‐1) and interleukin‐1 beta (IL‐1β), as well as suppression of glial glutamate transport function in the spinal cord. Intrathecal injection of either the CSF‐1 blocker or IL‐1 inhibitor attenuated thermal hyperalgesia in MRL/lpr mice. We provide evidence that the suppressed activity of glial glutamate transporters in the spinal dorsal horn in MRL/lpr mice is caused by activation of the CSF‐1 and IL‐1β signaling pathways. Our findings suggest that targeting the CSF‐1 and IL‐1β signaling pathways or the glial glutamate transporter in the spinal cord is an effective approach for the management of chronic pain caused by SLE.
Short-term Memory of Deep RNN

The extension of deep learning towards temporal data processing is gaining an increasing research interest. In this paper we investigate the properties of state dynamics developed in successive levels of deep recurrent neural networks (RNNs) in terms of short-term memory abilities. Our results reveal interesting insights that shed light on the nature of layering as a factor of RNN design. Noticeably, higher layers in a hierarchically organized RNN architecture results to be inherently biased towards longer memory spans even prior to training of the recurrent connections. Moreover, in the context of Reservoir Computing framework, our analysis also points out the benefit of a layered recurrent organization as an efficient approach to improve the memory skills of reservoir models.
Viability assessment of turkey sperm using fluorescent staining and flow cytometry.

Turkey sperm viability was evaluated using several fluorescent stains both singularly and in combination. Dilution curves and several extenders were used to determine optimal stain concentrations. Semen was collected from eight toms, pooled, diluted, stained, and evaluated microscopically within 2 h of collection. Replicates were assessed for both viable and nonviable sperm (green and red fluorescence, respectively) using flow cytometry. SYBR-14, which likely requires membrane potential for optimal fluorescence, or Calcein AM (CAL), which assesses the membrane integrity of cells (both green fluorescence), in combination with propidium iodide (PI) to stain the dead or degenerating cells (red fluorescence) provided optimal results. Sperm were killed by unprotected freeze-thawing to provide mixed aliquots containing known amounts of fresh:killed sperm. The percentage of viable sperm, as determined by SYBR-14 with PI or CAL with PI staining, were 76.6, 58.8, 39.3, 20.1, 8, and 73.5, 55.8, 36.0, 17.1, . 4, respectively, for ratios of 100:0, 75: 25, 50:50, 25:75, and 0:100 of fresh:killed mixtures. Semen from 30 individual toms was collected on 2 d and examined in replicate using these staining combinations. The proportion of viable sperm, as indicated by uptake of SYBR-14 or CAL stain, ranged from 55.8 to 86.7 and 38.0 to 86.1, respectively. Staining combinations were effective in estimating the viability of turkey sperm and could be useful for monitoring sperm viability before and after storage.
Investigating the Spillover Effect of Keyword Market Entry in Sponsored Search Advertising

As Internet advertising infomediaries nowadays provide rich competition information, sponsored search advertisers are becoming more strategic when selecting keywords. This paper empirically examines the spillover effects in advertisers’ keyword market entry decisions, that is, how an advertiser’s likelihood of using a keyword is affected by competitors’ keyword entry decisions. We develop a structural model to characterize advertisers’ keyword market entry decisions. We apply the model to a panel data set of 1,252 laptop-related keywords mainly used by 28 manufacturers, retailers, and comparison websites that advertise on Google. Our analysis leads to several interesting findings. First, an advertiser’s expected position affects the nature of the competition. In particular, the spillover effect from below-ranked competitors is always positive, while the spillover effect from above-ranked competitors is either positive or negative. Second, the spillover effect from above-ranked ads is directionally affecte.
