Plant diversity in a changing world: Status, trends, and conservation needs
Plant Diversity, 2016 The conservation of plants has not generated the sense of urgency—or the funding—that drives the conservation of animals, although plants are far more important for us.

How to conserve threatened Chinese plant species with extremely small populations?
Plant Diversity, 2016 The Chinese flora occupies a unique position in global plant diversity, but is severely threatened. Although biodiversity conservation in China has made significant progress over the past decades, many wild plant species have extremely small population ...

The origin of human chromosome 2 analyzed by comparative chromosome mapping with a DNA microlibrary [PDF]
, 1994 Fluorescencein situ hybridization (FISH) of microlibraries established from distinct chromosome subregions can test the evolutionary conservation of chromosome bands as well as chromosomal rearrangements that occurred during primate evolution and will ...

Nail Matrix Melanoma in situ: Conservative Surgical Management
Dermatology, 2009 <i>Background:</i> Nail unit melanoma (NUM) is a rare variant of acral lentiginous melanoma. The differential diagnosis is wide but an acquired brown streak in the nail of a fair-skinned person must be considered a potential melanoma. Dermatoscopy helps clinicians to more accurately decide if a nail apparatus biopsy is necessary.

Planning the integration of ex situ plant conservation in Tasmania [PDF]
, 2013 Tasmania has a strong record of successful in situ plant conservation but there will always be a role for the integration of various ex situ measures into a plant conservation program due to pressure by threatening processes on wild populations.

The newfound relationship between extrachromosomal DNAs and excised signal circles
FEBS Letters, EarlyView.Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS
FEBS Letters, EarlyView.We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...
