Assessing understanding of relative clauses: a comparison of multiple-choice comprehension versus sentence repetition
Liver transplantation today
In summary, liver transplantation has truly come of age. To put things in perspective, the recipient waiting list at the University of Pittsburgh never includes fewer than 200 suitable candidates, and it continues to grow in spite of the fact that we are now doing essentially one transplant per day. There are many excellent transplant centers throughout the United States and Europe, the only limiting factor being the supply of donors. Orthotopic liver transplantation is now covered by most major health insurance carriers, and some form of government coverage is anticipated for the indigent. As the supply of donors increases with aggressive education programs, the need for transplantation centers will also increase. However, this should not be uncontrolled growth. Mandatory training in transplantation surgery will surely be required as a prerequisite to the establishment of transplant centers in the future. The field of organ transplantation is the newest and most dynamic in medicine today. The results are encouraging and acceptable and offer the only hope to many persons dying of end-stage organ failure. With improvements in immune modulation at hand, organ transplantation will soon become a commonplace procedure offering a completely normal life expectancy

Monitoring and Pay: An Experiment on Employee Performance under Endogenous Supervision
We present an experimental test of a shirking model where monitoring intensity is endogenous and effort a continuous variable. Wage level, monitoring intensity and consequently the desired enforceable effort level are jointly determined by the maximization problem of the firm. As a result, monitoring and pay should be complements. In our experiment, between and within treatment variation is qualitatively in line with the normative predictions of
the model under standard assumptions. Yet, we also find evidence for reciprocal behavior. Our data analysis shows, however, that it does not pay for the employer to solely rely on the reciprocity of employees

PARP-1 regulates DNA repair factor availability.
PARP-1 holds major functions on chromatin, DNA damage repair and transcriptional regulation, both of which are relevant in the context of cancer. Here, unbiased transcriptional profiling revealed the downstream transcriptional profile of PARP-1 enzymatic activity. Further investigation of the PARP-1-regulated transcriptome and secondary strategies for assessing PARP-1 activity in patient tissues revealed that PARP-1 activity was unexpectedly enriched as a function of disease progression and was associated with poor outcome independent of DNA double-strand breaks, suggesting that enhanced PARP-1 activity may promote aggressive phenotypes. Mechanistic investigation revealed that active PARP-1 served to enhance E2F1 transcription factor activity, and specifically promoted E2F1-mediated induction of DNA repair factors involved in homologous recombination (HR). Conversely, PARP-1 inhibition reduced HR factor availability and thus acted to induce or enhance BRCA-ness . These observations bring new understanding of PARP-1 function in cancer and have significant ramifications on predicting PARP-1 inhibitor function in the clinical setting
Advancing national animal health and welfare policy
The University College Dublin (UCD) School of Veterinary Medicine has a broad research agenda covering areas such as veterinary public health, epidemiology and national disease control, herd health management, drug delivery, pharmacology, parasitology, and One Health research. We work with national and international collaborators and, with the support of Zoetis, have a longstanding “UCD Squared” partnership with the University of California-Davis, which has established an ambitious program of research, drawing on expertise from a diverse community of veterinary and medical scientists and clinicians.Unusual, not sure if it can be called Journal Article or should be under another type perhap
MYC pathway activation in triple-negative breast cancer is synthetic lethal with CDK inhibition
Estrogen, progesterone, and HER2 receptor-negative triple-negative breast cancers encompass the most clinically challenging subtype for which targeted therapeutics are lacking. We find that triple-negative tumors exhibit elevated MYC expression, as well as altered expression of MYC regulatory genes, resulting in increased activity of the MYC pathway. In primary breast tumors, MYC signaling did not predict response to neoadjuvant chemotherapy but was associated with poor prognosis. We exploit the increased MYC expression found in triple-negative breast cancers by using a synthetic-lethal approach dependent on cyclin-dependent kinase (CDK) inhibition. CDK inhibition effectively induced tumor regression in triple-negative tumor xenografts. The proapoptotic BCL-2 family member BIM is up-regulated after CDK inhibition and contributes to this synthetic-lethal mechanism. These results indicate that aggressive breast tumors with elevated MYC are uniquely sensitive to CDK inhibitors
