The rapid growth in molecular diagnostic testing, which has averaged between 10% and 20% per year for the past 5 years, is largely attributable to both breakthroughs in our basic understanding (i.e., the Human Genome Project) and in applied technology. In the past decade, molecular applications have moved from labor-intensive and manual to rapid and automated due to improvements in sample extraction, target amplification, and sensitive and specific detection schema. This review describes some of the more significant technological milestones of the past 10 years and, when tied to basic and applied research, how these have led to important clinical applications. The next decade promises even more exciting technologies and applications for the field of molecular laboratory medicine.

Scrolled Poly(L-lactic acid) Single Crystals via Chain End-Induced Symmetry-Breaking.
Angew Chem Int Ed Engl

The University of Tennessee Knoxville, Chemistry, UNITED STATES OF AMERICA.
Single crystals that do not obey translational symmetry have been reported in various material systems. In polymers, twisted crystals are typically formed in banded spherulites, while a class of non-flat polymer single crystals (PSCs) has been observed. Herein, we report the formation of scrolled single crystals of biodegradable polymer poly(L-lactic acid) (PLLA).

We aimed to explore the role of Amino acid metabolism (AAM) and identify biomarkers for prognosis management and treatment of lung adenocarcinoma. Differentially expressed genes (DEGs) associated with AAM in lung adenocarcinoma were selected from public databases. Samples were clustered into varying subtypes using ConsensusClusterPlus based on gene levels.

As an important receptor in a host's immune and metabolic systems, NOD1 is usually activated by Gram-negative bacteria having -diaminopimelic acid (-DAP) in their peptidoglycan (PGN). But some atypical Gram-positive bacteria also contain -DAP in their PGN, giving them the potential to activate NOD1. The prevalence of -DAP-type Gram-positive bacteria in the gut, however, remains largely unknown.

Cell lineage analysis is primarily undertaken to understand cell fate specification and diversification along a cell lineage tree. Built with dual repressible markers, twin-spot mosaic analysis with repressible cell markers (MARCM) labels the two daughter cells made by a common precursor in distinct colors. The power of twin-spot MARCM to systematically subdivide complex lineages is exemplified in studies of Drosophila neural stem-cell lineages.

The recent development of genetic lineage recorders, designed to register the genealogical history of cells using induced somatic mutations, has opened the possibility of reconstructing complete animal cell lineages. To reconstruct a cell lineage tree from a molecular recorder, it is crucial to use an appropriate reconstruction algorithm. Current approaches include algorithms specifically designed for cell lineage reconstruction and the repurposing of phylogenetic algorithms.
