Outcomes and Surgical Management of Malignant Rhabdoid Tumor of the Kidney: A Report From the Pediatric Surgical Oncology Research Collaborative

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Purpose Malignant rhabdoid tumor of the kidney (MRTK) is a rare, aggressive tumor seen in young children. The optimal timing of resection for locally advanced tumors is not well‐defined. The purpose of this study is to evaluate modern oncologic outcomes and the impact of surgical timing. Methods A multicenter retrospective review was performed

Genetic and Morphological Variation Among Populations of Duckweed Species in Thailand

open access: yesPlants
Duckweeds have emerged as frontier plants in research, food, and bioenergy applications. Consistency in genetic and morphological traits within species is therefore crucial for their effective use.

VARIASI GENETIK LOCI STR CODIS (THO1,TPOX) MANUSIA GILIMANUK (PULAU BALI)

open access: yesBerkala Arkeologi, 2013
It is assumed that Mongoloid’s migration came from western and northern part of Indonesia in various waves of migration. The migrant population then mixed with initial inhabitants, which are Australomelanesoid.

Genetic variation stimulated by epigenetic modification. [PDF]

open access: yesPLoS ONE, 2008
Homologous recombination is essential for maintaining genomic integrity. A common repair mechanism, it uses a homologous or homeologous donor as a template for repair of a damaged target gene.

Continental-scale patterns of pathogen prevalence: a case study on the corncrake [PDF]

open access: yes, 2014
Pathogen infections can represent a substantial threat to wild populations, especially those already limited in size. To determine how much variation in the pathogens observed among fragmented populations is caused by ecological factors, one needs to ...

MYCN Amplification in RB1‐Inactivated Retinoblastoma: Association With High‐Risk Features

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background MYCN amplification occurs in a subset of retinoblastoma cases, both with and without RB1 inactivation. It has been suggested that retinoblastomas with MYCN amplification represent a distinct entity with more aggressive clinical behavior.

Multiple FLC haplotypes defined by independent cis-regulatory variation underpin life history diversity in Arabidopsis thaliana [PDF]

open access: yes, 2014
Relating molecular variation to phenotypic diversity is a central goal in evolutionary biology. In Arabidopsis thaliana, FLOWERING LOCUS C (FLC) is a major determinant of variation in vernalization—the acceleration of flowering by prolonged cold.

Adjunctive Therapeutic Plasma Exchange in Refractory Adult‐Onset Still's Disease Complicated by Secondary Macrophage Activation Syndrome: A Single‐Center Experience

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Adult‐onset Still's disease (AOSD) complicated by macrophage activation syndrome (MAS) carries substantial mortality. The role of therapeutic plasma exchange (TPE) remains uncertain. Methods We retrospectively analyzed patients with AOSD‐MAS treated with TPE at a single‐center.

Cirsium species show disparity in patterns of genetic variation at their range-edge, despite similar patterns of reproduction and isolation [PDF]

open access: yes, 2003
Genetic variation was assessed across the UK geographical range of Cirsium acaule and Cirsium heterophyllum. A decline in genetic diversity and increase in population divergence approaching the range edge of these species was predicted based on parallel ...
