- These guidelines are a consensus work of a considerable number of members of the immunology and flow cytometry community. They provide the theory and key practical aspects of flow cytometry enabling immunologists to avoid the common errors that often undermine immunological data. Notably, there are comprehensive sections of all major immune cell types with helpful Tables detailing phenotypes in murine and human cells. The latest flow cytometry techniques and applications are also described, featuring examples of the data that can be generated and, importantly, how the data can be analysed. Furthermore, there are sections detailing tips, tricks and pitfalls to avoid, all written and peer-reviewed by leading experts in the field, making this an essential research companion.

- SARS-CoV-2 transmission mainly occurs through exposure of the upper airway mucosa to infected secretions such as saliva, which are excreted by an infected person. Thus, oral mucosal immunity plays a central role in the prevention of and early defense against SARS-CoV-2 infection. Although virus-specific antibody response has been extensively investigated in blood samples of SARS-CoV-2-infected patients and vaccinees, local humoral immunity in the oral cavity and its relationship to systemic antibody levels needs to be further addressed.Material and MethodsWe fine-tuned a virus neutralization assay (vNTA) to measure the neutralizing activity (NA) of plasma and saliva samples from 20 SARS-CoV-2-infected (SI), 40 SARS-CoV-2-vaccinated (SV), and 28 SARS-CoV-2-vaccinated subjects with a history of infection (SIV) using the “wild type” SARS-CoV-2 lineage B.1 (EU) and the Delta (B.1.617.2) strains. To validate the vNTA results, the presence of neutralizing antibodies (NAbs) to the spike receptor binding domain (RBD) was evaluated with an ELISA assay.ResultsNA to SARS-CoV-2 lineage B.1 (EU) was present in plasma samples from all the tested subjects, with higher titers in SIV compared to both SI and SV. Conversely, NA was detected in saliva samples from 10.3% SV, 45% SI, and 92.6% SIV, with significantly lower titers in SV compared to both SI and SIV. The detection of NAbs in saliva reflected its reduced NA in SV.DiscussionThe difference in NA of plasma vs. saliva was confirmed in a vNTA where the SARS-CoV-2 B.1 and Delta strains were tested head-to-head, which also revealed a reduced NA of both specimens compared to the B.1 variant.ConclusionsThe administration of SARS-CoV-2 vaccines was associated with limited virus NA in the oral cavity, as measured in saliva and in comparison to plasma. This difference was more evident in vaccinees without a history of SARS-CoV-2 infection, possibly highlighting the importance of local exposure at the site of virus acquisition to effectively prevent the infection and block its spread. Nevertheless, the presence of immune escape mutations as possibly represented by the SARS-CoV-2 Delta variant negatively affects both local and systemic efficacy of NA associated with vaccination.

Forskningsöversikt (refereegranskat)abstract
- The grand challenges of contemporary fundamental physics dark matter, dark energy, vacuum energy, inflation and early universe cosmology, singularities and the hierarchy problem all involve gravity as a key component. And of all gravitational phenomena, black holes stand out in their elegant simplicity, while harbouring some of the most remarkable predictions of General Relativity: event horizons, singularities and ergoregions. The hitherto invisible landscape of the gravitational Universe is being unveiled before our eyes: the historical direct detection of gravitational waves by the LIGO-Virgo collaboration marks the dawn of a new era of scientific exploration. Gravitational-wave astronomy will allow us to test models of black hole formation, growth and evolution, as well as models of gravitational-wave generation and propagation. It will provide evidence for event horizons and ergoregions, test the theory of General Relativity itself, and may reveal the existence of new fundamental fields. The synthesis of these results has the potential to radically reshape our understanding of the cosmos and of the laws of Nature. The purpose of this work is to present a concise, yet comprehensive overview of the state of the art in the relevant fields of research, summarize important open problems, and lay out a roadmap for future progress. This write-up is an initiative taken within the framework of the European Action on 'Black holes, Gravitational waves and Fundamental Physics'.

- Background: Since 2015 operations performed in the field of endocrine surgery have been entered into the European registry EUROCRINE®. The aim of this analysis was a description of the current healthcare situation for adrenal surgery in a homogeneous healthcare environment corresponding to the German-speaking countries—or to the presence of the working group on surgical endocrinology (CAEK) of the German society for general and visceral surgery (DGAV)—and to assess the adherence to current international treatment guidelines. Methods: An analysis of the preoperative diagnostics, the applied operative techniques and the underlying histological entities was carried out for all operations on adrenal glands in Germany, Switzerland and Austria, which were registered in EUROCRINE® from 2015 to 2019. Results: In the total of 21 participating hospitals from the German-speaking EUROCRINE® countries, 658 operations on adrenal glands were performed. In 90% of cases unilateral adrenalectomy was performed, in 3% bilateral adrenalectomy and in 7% other resection procedures. In 41% the main histological diagnosis was an adrenocortical adenoma. In 15% malignant entities were detected on final histology, including 6% adrenocortical carcinoma (ACC) and 8% metastases to the adrenal glands. 23% of the operations were performed for pheochromocytoma. This entity was primarily resected using minimally invasive approaches (82%), whereas minimally invasive techniques were applied in 28% for ACC and in 66% for metastases to the adrenal glands. Conclusion: Surprisingly, following adrenocortical adenoma and pheochromocytoma, the third most common histological entity was metastasis of different extra-adrenal primary tumors to the adrenal gland. Of the operations for ACC 28% were scheduled for minimally invasive techniques, but conversion to open surgery was necessary in 20%. The analysis revealed discrepancies between treatment reality and international guideline recommendations that raise questions, which will be addressed by an updated version of the EUROCRINE® module for the documentation of adrenal surgery.
