Intrapatient tumour heterogeneity and clonal evolution in an autopsy study of metastatic salivary gland cancer

open access: yesMolecular Oncology, EarlyView.
Tumour heterogeneity and clonal evolution of metastatic salivary gland cancer were evaluated in two patients with adenoid carcinoma and one patient with myoepithelial carcinoma. Radiology‐guided autopsy enabled multi‐region sampling (total samples n = 149), followed by whole‐genome sequencing and phylogenetic reconstruction (17 tumour samples, 4–7 per ...

Somatostatin receptor 4 (SSTR4) is a tumor suppressor in cutaneous and head & neck squamous cell carcinomas

open access: yesMolecular Oncology, EarlyView.
This study identifies somatostatin receptor 4 (Sstr4) as a critical tumor suppressor against skin and head/neck cancers (HNSCC, cSCC, and BCC). The loss of Sstr4 removes a check on cell growth, causing hyperactivation of the MAPK‐ERK signaling pathway (↑).

ADP‐ribosylation: An emerging regulator of the epigenome

open access: yesMolecular Oncology, EarlyView.
ADP‐ribosylation has emerged as a dynamic epigenetic signaling mechanism that modifies histones and chromatin‐associated proteins. Through coordinated PARylation and MARylation, it integrates with other histone modifications to regulate chromatin structure, transcription factor activity, and gene expression, influencing genome function and disease ...

Raman‐based label‐free microscopic analysis of the pancreas in living zebrafish larvae

open access: yesFEBS Open Bio, EarlyView.
Forward stimulated Raman scattering (F‐SRS) and epi coherent anti‐Stokes Raman scattering (E‐CARS) allow label‐free discrimination of distinct subcellular structures in the pancreas of living zebrafish larvae. Given the straightforward applicability, we anticipate broad implementation of Raman microscopy in other organs and across various biomedical ...

Polarization‐resolved femtosecond Vis/IR spectroscopy tailored for resolving weak signals in biological samples using minimal sample volume

open access: yesFEBS Open Bio, EarlyView.
Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐

The chemical control of respiration

Annals of Biomedical Engineering, 1981
Arterial blood gas tensions are maintained at appropriate levels through a feedback system which adjusts ventilation and has multiple inputs and outputs. Inputs to the system arise mainly from peripheral and central chemoreceptors, but there are other inputs from mechanoreceptors and higher brain centers.

Control of Chemical Pollutants

Nature, 1970
Concern for environmental quality and consumer safety is burgeoning, and some classic assumptions of industrial society are being challenged. Now that apparent conflicts have developed between the needs for continued economic growth and environmental management it is timely to review some of the basic problems of chemical pollution, to develop methods ...

Integration of Biological and Chemical Control: Specifications for Chemical Control

Bulletin of the Entomological Society of America, 1962
About 20 years ago economic entomology entered a highly productive period which was highlighted by the development of the synthetic organic insecticides, beginning, of course, when the insecticidal activity of DDT and BHC was discovered. Since that time the agricultural entomologist has been confronted with literally hundreds of new insecticides to be ...

Analytical Chemical Control of Phthalates in Toys:Analytical Chemical Control of Chemical Substances and Products

2001
The content of phthalates in toys and other articles for children up to 3 years of age is regulated by the Statutory Order of Danish Ministry of Environment and Energy, No. 151 of 15th March 1999. In the present investigation, 20 products (toys and other articles for children up to 3 years of age) were analysed for the content of phthalates on the ...
