Background: Increasing evidence suggests that some patients suffer from persistent symptoms for months after recovery from acute COVID-19. However, the clinical phenotype and its pathogenesis remain unclear. We here present data on complaints and results of a diagnostic workup of patients presenting to the post-COVID clinic at the University Medical Center Freiburg.

Its underlying pathophysiology, however, is unknown. In this study, we assessed cognitive profiles and regional cerebral glucose metabolism as a biomarker of neuronal function in outpatients with long-term neurocognitive symptoms after COVID-19.

Vaccine-induced CD8 T cells may therefore be the main mediators of protection at this early stage. The details of their induction, comparison to natural infection, and association with other arms of vaccine-induced immunity remain, however, incompletely understood.

Until now, the effects of DJBL on cardiovascular risk have never been investigated.
Methods: Between 2012 and 2017, 71 patients with T2D and metabolic syndrome (MS) were recruited for implantation of DJBL for 9-12 months.

Context: Maturity-onset diabetes of the young type 5 (MODY5) is caused by mutations of the hepatocyte nuclear factor 1 homeobox β gene (HNF1B). Although clinical characteristics and therapeutic management of MODY5 are increasingly better defined, adequate consideration of the frequent association of MODY5 with 17q12 deletion syndrome is often missing.
Evidence Acquisition: We report two cases of patients with 17q12 deletion syndrome who presented to our clinic.
Mono-ADP ribosylation of actin by bacterial toxins, such as Clostridium perfringens iota or Clostridium botulinum C2 toxins, results in rapid depolymerization of actin filaments and cell rounding. Here we report that treatment of African green monkey kidney (Vero) cells with iota toxin resulted in delayed caspase-dependent death. Unmodified actin did not reappear in toxin-treated cells, and enzyme-active toxin was detectable in the cytosol for at least 24 h.
