The current state of the quality of homeopathic clinical research.

Homeopathy is a system of therapeutics that treats disease with highly diluted substances based on the Law of Similars, which holds that "like cures like." Despite widespread use, homeopathy lacks a comprehensive and robust evidence base. We examined the state of homeopathic clinical research by critically assessing the overall quality of peer-reviewed, recently published, English-language, homeopathic clinical research in terms of internal, external, and model validity using standard and homeopathic-specific instruments.

A modified dual preparatory method for improved isolation of nucleic acids from laser microdissected fresh-frozen human cancer tissue specimens.

A central theme in cancer research is to increase our understanding of the cancer tissue microenvironment, which is comprised of a complex and spatially heterogeneous ecosystem of malignant and non-malignant cells, both of which actively contribute to an intervening extracellular matrix. Laser microdissection (LMD) enables histology selective harvest of cellular subpopulations from the tissue microenvironment for their independent molecular investigation, such as by high-throughput DNA and RNA sequencing. Although enabling, LMD often requires a labor-intensive investment to harvest enough cells to achieve the necessary DNA and/or RNA input requirements for conventional next-generation sequencing workflows.

Evolution of promoter-proximal pausing enabled a new layer of transcription control.

Promoter-proximal pausing of RNA polymerase II (Pol II) is a key regulatory step during transcription. Despite the central role of pausing in gene regulation, we do not understand the evolutionary processes that led to the emergence of Pol II pausing or its transition to a rate-limiting step actively controlled by transcription factors. Here we analyzed transcription in species across the tree of life.

How occupational therapists are incorporating information and communication technology into intervention with older adults: a scoping review.

Use of information and communication technology (ICT) (computers and smartphones) during everyday occupations is growing as rapidly as the older adult population. ICT is incorporated into occupational therapy (OT) interventions to improve performance in everyday activities. Limited competence in ICT can jeopardize wellness, autonomy, and contribute to isolation.
