Evaluating the impact of COVID-19 protection measures and staff absence on radiotherapy practice: A simulation study.

Background: Radiotherapy practice for cancer treatment is resource-intensive and demands optimised processes for patient throughput while guaranteeing the quality and safety of the therapy. With the COVID-19 pandemic, ad-hoc changes in the operation of radiotherapy centres became necessary to protect patients and staff. This simulation study aimed to quantify the impact of designated COVID-19 protection measures and pandemic-related staff absence on patient waiting times and throughput.

Proteomic insight into the primycin fermentation process of Saccharomonospora azurea.

Saccharomonospora azurea SZMC 14600 is a member of the family Pseudonocardiaceae exclusively used for industrial scale production of primycin a large 36-membered non-polyene macrolide lactone antibiotic belonging to the polyketide class of natural products. Even though maximum antibiotic yield has been achieved by empirically optimized two-step fermentation process, little is known about the molecular components and mechanisms underlying the efficient antibiotic production. In order to identify differentially expressed proteins (DEPs) between the pre- and main-fermentation stages of primycin, comparative 2D-PAGE experiments were performed.

Comparative protein composition of the brains of PACAP-deficient mice using mass spectrometry-based proteomic analysis.

Pituitary adenylate cyclase-activating polypeptide (PACAP) is a widespread neuropeptide acting as a neurotransmitter, neuromodulator, or neurotrophic factor. The diverse biological actions provide the background for the variety of deficits observed in mice lacking endogenous PACAP. PACAP-deficient mice display several abnormalities, such as sudden infant death syndrome (SIDS)-like phenotype, decreased cell protection, and increased risk of Parkinson's disease.

Mass spectrometric identification of ancient proteins as potential molecular biomarkers for a 2000-year-old osteogenic sarcoma.

Osteosarcoma is the most common primary malignant tumor of bone usually occurring in young adolescent and children. This disease has a poor prognosis, because of the metastases in the period of tumor progression, which are usually developed previous to the clinical diagnosis. In this paper, a 2000-year-old ancient bone remain with osteogenic sarcoma was analyzed searching for tumor biomarkers which are closely related to this disease.

Preparation and investigation of LC packing made by microwave-assisted solid-phase synthesis.

The preparation of the so-called bonded phase liquid chromatographic packings is usually carried out by heating the silica, the silane, a catalyst, or a scavenger in an appropriate solvent (often toluene.) Due to the longtime of boiling, the procedure is time and energy consuming, and solvent intensive. The goal of this work is to present a simple, environment-friendly preparation method with reduced solvent consumption to synthetize RP liquid chromatographic stationary phases.
