Biphasic Clinical Course of Pediatric Cytomegalovirus‐Associated Immune Thrombocytopenia: Early Poor Treatment Response but Favorable Long‐Term Outcomes

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Cytomegalovirus (CMV) is a recognized trigger of immune thrombocytopenia (ITP); however, its incidence and impact on disease course in children remain controversial. Therefore, we aimed to characterize the clinical course of pediatric patients with CMV‐associated ITP.

The Great Divergence Reconsidered: Or, Is it Time to Reconsider the Great Divergence Debate? [PDF]

International Journal for History, Culture and Modernity, 2019
Twenty years ago, Kenneth Pomeranz’s The Great Divergence (2000) reshaped debates over the historical causes of Europe’s rapid nineteenthcentury industrialization and economic growth. By comparing the Yangzi Delta region of China to Britain, Pomeranz asserted that Europe was not exceptionally dynamic before the nineteenth century and that its ...

Estimating Divergence Times in Large Phylogenetic Trees [PDF]

Systematic Biology, 2007
A new method, PATHd8, for estimating ultrametric trees from trees with edge (branch) lengths proportional to the number of substitutions is proposed. The method allows for an arbitrary number of reference nodes for time calibration, each defined either as absolute age, minimum age, or maximum age, and the tree need not be fully resolved.

Potential for bias and low precision in molecular divergence time estimation of the Canopy of Life: an example from aquatic bird families

Frontiers in Genetics, 2015
Uncertainty in divergence time estimation is rarely studied from the perspective of phylogenetic node age. If available models fail to completely account for rate heterogeneity, substitution saturation and incompleteness of the fossil record, uncertainty

Bone Mineral Density After Contemporary Treatment for Acute Lymphoblastic Leukaemia: A Matched Cross‐Sectional Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Reduced bone mineral density (BMD) has been reported in survivors of childhood and young adult acute lymphoblastic leukaemia (ALL); however, data from cohorts treated with contemporary protocols and including matched controls remain limited.

Plastid phylogenomics illuminates backbone relationships, divergence times and character evolution in Caryophyllaceae

BMC Plant Biology
Background The family Caryophyllaceae has traditionally been divided into three subfamilies (i.e. Alsinoideae, Caryophylloideae, Paronychioideae). However, the monophyly of each subfamily has been challenged, while boundaries, phylogenetic relationships,
