[Adaptation of infection protection measures in public services due to the COVID-19 pandemic].

The COVID-19 pandemic is changing the requirements for occupational health and safety in the workplace. The aim of the measures implemented nationwide is to reduce the spread of the virus. This applies to all areas of life, including the workplace.

[Classroom teaching at universities and colleges under the conditions of the SARS-CoV-2 pandemic].

In order to maintain university teaching while observing the distance rules in accordance with the occupational health and safety standard of the German Federal Ministry of Labour and Social Affairs (BMAS), special regulations and measures must be observed under the conditions of the COVID-19 pandemic when students and teaching staff meet in large groups (lecture hall) and small teaching rooms (seminars, internships). The article gives detailed recommendations for the practical implementation of protective and preventive measures according to the STOP principle, which is customary in occupational health and safety: substitution, technical, organisational and personal protective measures. Responsibilities are named and also difficult situations where physical proximity is necessary (e.

Comparison of tear protein levels in breast cancer patients and healthy controls using a de novo proteomic approach.

Noninvasive biomarkers are urgently needed for early detection of breast cancer since the risk of recurrence, morbidity and mortality are closely related to disease stage at the time of primary surgery. In the past decade, many proteomics-based approaches were developed that utilize the protein profiling of human body fluids or identification of putative biomarkers to obtain more knowledge on the effects of cancer emergence and progression. Herein, we report on an analysis of proteins in the tear fluid from breast carcinoma patients and healthy women using a de novo proteomic approach and 25 mixed samples from each group.
