Is COVID-19 Associated With Posttraumatic Stress Disorder?

Objective: To assess the prevalence of and risk factors for posttraumatic stress disorder (PTSD) in patients with COVID-19.

Methods: We conducted a cohort study between March and May 2020 at the Lille University Hospital (France), including all patients with laboratory-confirmed COVID-19. Psychological distress symptoms were measured 3 weeks after onset of COVID-19 symptoms using the Impact of Event Scale-6 items (IES-6).

Tumor necrosis factor alpha in human kidney transplant rejection--analysis by in situ hybridization.

Macrophagic infiltration and necrosis of rejected kidney transplants represent two pejorative patterns. It has been assumed that the macrophagic toxicity is mediated partly by secretion of tumor necrosis factor alpha. On the other hand, TNF is also involved in many inflammatory and immunological phenomena.

Protective effect of bone marrow and spleen suspensions on radiation-induced leukemogenesis in C57BL/6 mice.

The present experiments are an attempt to precise the type and localization of the cells involved in the protective effect of hemopoietic suspensions against the radiation-induced thymic lymphosarcoma (TLS) of C57BL/6 mice. Inocula containing variable numbers of BM or spleen CFUs from 60-day-old and 360-day-old donors were tested. According to their origin, the suspensions differed with respect to the CFU replication rate, the CFU ability to differentiate towards the T lineage and the content of the suspensions in thymic precursors.

Bovine lymphosarcoma: processing of bovine leukaemia virus-coded proteins.

This report describes pulse-chase experiments performed with cells infected with tumour-derived bovine leukaemia virus (BLV) and using purified gamma-globulins directed against BLV structural proteins, namely gp51, p24, p15 and p12. A gpr72 was found to be the precursor of the gp51 with a gpr70 intermediate. The p12 was shown to be derived from a pr40 with numerous intermediates (pr35, pr22, pr16 and pr14).
