Recognition of histone covalent modifications by 'reader' modules constitutes a major mechanism for epigenetic regulation. A recent upsurge of newly discovered histone lysine acylations, such as crotonylation (Kcr), butyrylation (Kbu), and propionylation (Kpr), greatly expands the coding potential of histone lysine modifications. Here we demonstrate that the histone acetylation-binding double PHD finger (DPF) domains of human MOZ (also known as KAT6A) and DPF2 (also known as BAF45d) accommodate a wide range of histone lysine acylations with the strongest preference for Kcr...

OBJECTIVE: to develop and validate a self-administered online questionnaire to assess basic competence about breastfeeding in the full range of health professionals attending lactating mothers in primary care. DESIGN: methodological study. SETTINGS: the study was conducted in 33 primary care centers administered by the Catalan Health Institute (Institut Català de la Salut) in the Girona Region (northeast Spain)...

The Prolyl Hydroxylase Domain protein (PHD):Hypoxia Inducible Factor (HIF) pathway is the main pathway by which changes in oxygen concentration are transduced to changes in gene expression. In mammals, there are three PHD paralogues, and PHD2 has emerged as a particularly critical one for regulating HIF target genes such as ERYTHROPOIETIN (EPO), which controls red cell mass and hematocrit. PHD2 is distinctive among the three PHDs in that it contains an N-terminal MYND type zinc finger. We have proposed that this zinc finger binds a Pro-Xaa-Leu-Glu (PXLE) motif found in proteins of the HSP90 pathway to facilitate HIF-α hydroxylation...

The entry of small molecule inhibitors of the bromodomain and extra C-terminal domain (BET) family of bromodomains into the clinic has demonstrated the therapeutic potential for this class of epigenetic acetyl-lysine reader proteins. Within the past two years, the development of potent inhibitors for the bromodomain and PHD finger containing protein (BRPF) family and the tripartite motif containing protein 24 (TRIM24) have been reported and are the subject of this review. Both proteins contain other domains with diverse functions and can also be part of a complex of proteins which have implications in epigenetic signaling and disease...

PhD-trained biomedical scientists are moving into an increasingly diverse variety of careers within the sciences. However, our graduate and postdoctoral training programs have historically focused on academic career preparation, and have not sufficiently prepared trainees for transitioning into other scientific careers. Advocates for science have raised the concern that our collective disregard of the broader career development needs for predoctoral and postdoctoral trainees could drive talent away from science in upcoming generations...

PHF20 is a core component of the lysine acetyltransferase complex MOF (male absent on the first)-NSL (non-specific lethal) that generates the major epigenetic mark H4K16ac and is necessary for transcriptional regulation and DNA repair. The role of PHF20 in the complex remains elusive. Here, we report on functional coupling between methylation readers in PHF20. We show that the plant homeodomain (PHD) finger of PHF20 recognizes dimethylated lysine 4 of histone H3 (H3K4me2) and represents an example of a native reader that selects for this modification...

Objective. To compare the net cumulative income of community pharmacists, hospital pharmacists, and full-time pharmacy faculty members (residency-trained or with a PhD after obtaining a PharmD) in pharmacy practice, medicinal chemistry, pharmaceutics, pharmacology, and social and administrative sciences. Methods. Markov modeling was conducted to calculate net projected cumulative earnings of career paths by estimating the costs of education, including the costs of obtaining degrees and student loans. Results...

Pluripotent embryonic stem cells (ESCs) self-renew or differentiate into all tissues of the developing embryo and cell-specification factors are necessary to balance gene expression. Here we delineate the function of the PHD-finger protein 5a (Phf5a) in ESC self-renewal and ascribe its role in regulating pluripotency, cellular reprogramming and myoblast specification. We demonstrate that Phf5a is essential for maintaining pluripotency, since depleted ESCs exhibit hallmarks of differentiation. Mechanistically, we attribute Phf5a function to the stabilization of the Paf1 transcriptional complex and control of RNA polymerase II elongation on pluripotency loci...

This dataset describe microclimatic parameters of two urban open public spaces in the city of Belo Horizonte, Brazil; physiological equivalent temperature (PET) index values and the related subjective responses of interviewees regarding thermal sensation perception and preference and thermal comfort evaluation. Individuals and behavioral characteristics of respondents were also presented. Data were collected at daytime, in summer and winter, 2013. Statistical treatment of this data was firstly presented in a PhD Thesis ("Percepção sonora e térmica e avaliação de conforto em espaços urbanos abertos do município de Belo Horizonte - MG, Brasil" (Hirashima, 2014) [1]), providing relevant information on thermal conditions in these locations and on thermal comfort assessment...

Numerous ranking systems exist for the quantification of tooth wear, each unfortunately with its own particular shortcomings. In this dissertation a new and very comprehensive tooth wear evaluation system is described. In it, the existing terminology is adapted to distinguish among mechanical-intrinsic (formerly attrition), mechanical-extrinsic (formerly abrasion), chemical-intrinsic (formerly erosion) and chemical-extrinsic (formerly erosion). In order to indicate the degree of wear, the terms mild, moderate, serious and severe are used...

Ubiquitin-like with PHD and ring finger domains 2 (UHRF2) binds to 5-hydroxymethylcytosine (5hmC), a DNA base involved in tissue development, but it is unknown how their distribution compares with each other in normal and malignant human tissues. We used IHC on human tumor specimens (160 from 19 tumor types) or normal tissue to determine the expression and distribution of UHRF2, Ki-67, and 5hmC. We also examined UHRF2 expression in cord blood progenitors and compared its expression to methylation status in 6 leukemia cell lines and 15 primary human leukemias...

Recent decades have seen a sharp increase in the number of female PhD graduates in the Netherlands. Currently, the share of females among newly graduated PhDs is almost on par with that of males. A considerable body of scientific studies has investigated the role of gender in the academic workplace. However, the role of gender in the careers of all PhD graduates, including those outside academia, has been studied less. In this study, we investigate gender differences in type of job, occupation, career perception and research performance of recent PhDs...

BACKGROUND: We aimed to investigate the impact of taking dedicated time for research (DTR) during training and/or getting a PhD on subsequent career achievements of US academic cardiothoracic surgeons. METHODS: Online resources (institutional Web sites, CTSNet, Scopus, NIH RePORTER) were queried to collect training information (timing of medical school/residency/fellowship graduation, DTR, PhD) and academic metrics (publications, citations, research funding) for 694 academic cardiothoracic surgeons practicing at 56 premiere US institutions...
