Annual Review of Microbiology, 1981
Abstract An inducible antibacterial activity is a main part of the immune system of the Cecropia moth and several other insects. The active material is a family of small proteins called cecropins. Sequence work shows that at least two of the cecropins originate from a gene duplication.

Circulating cell free DNA: Preanalytical considerations
Clinica Chimica Acta, 2013Despite the growing interest in circulating cell-free DNA (ccfDNA) analysis in various clinical fields, especially oncology and prenatal diagnosis, few studies on sample handling have been reported and no analytical consensus is available. The lack of consistency between the various protocols for sample handling and the techniques used for ccfDNA ...

Cell-Free Biosystems for Biomanufacturing
2012Although cell-free biosystems have been used as a tool for investigating fundamental aspects of biological systems for more than 100 years, they are becoming an emerging biomanufacturing platform in the production of low-value biocommodities (e.g., H(2), ethanol, and isobutanol), fine chemicals, and high-value protein and carbohydrate drugs and their ...

Cell-free DNA: Preanalytical variables
Clinica Chimica Acta, 2015Since the discovery of cell-free DNA (cfDNA) in human blood, most studies have focused on diagnostic and prognostic uses of these markers for solid tumors. Except for some prenatal tests and BEAMing, cfDNA analysis has not yet been translated to clinical practice and routine application appears distant. This can be attributed to overlapping factors: (i)

The analysis of cell-free DNA (cfDNA) has emerged as a cornerstone of minimally invasive liquid biopsies. We summarize the key advancements of the last five years-deepening insights into fundamental cfDNA biology, innovations in wet- and dry-lab approaches, and the amassment of clinical outcome data-and discuss prospects of this field for the coming ...

Cell free systems for biodesign
Cell-free systems (CFS) have emerged as transformative tools in synthetic biology, enabling the execution of complex biological reactions such as transcription and translation outside the confines of living cells. By eliminating the cellular membrane, CFS allows unprecedented control over biochemical conditions, facilitating rapid prototyping (up to ...Mohd, Tariq +6 more

Cell-free DNA (cfDNA) found in the plasma or serum is derived from multiple sources, including tumor cells. The fraction of cfDNA derived from tumor cells is termed circulating tumor DNA (ctDNA). Despite the low levels of ctDNA in normal cfDNA, advances in digital polymerase chain reaction (PCR) and next-generation sequencing (NGS) technologies have ...

Biosensing has precise sensitivity and high specificity, and the potential use of biosensor ranges from environmental monitoring, food safety, to disease diagnosis [1]. Biosensing is using the biological sensing element to detect some substances, include inorganic molecules, disease biomarkers, and others.

Future wireless networks will have to manage billions of devices at once, and each one needs a high throughput to serve a range of applications, including speech, real-time video, high-definition video, and others. Due to the excessively high interference levels and poor performance of user equipment (UEs) at the cell boundary, cellular networks are ...
