Ozone treatment effectively eliminates SARS-CoV-2 from infected face masks.

The current COVID-19 pandemic is causing profound health, economic, and social problems worldwide. The global shortage of medical and personal protective equipment (PPE) in specialized centers during the outbreak demonstrated the need for efficient methods to disinfect and recycle them in times of emergency. We have previously described that high ozone concentrations destroyed viral RNA in an inactivated SARS-CoV-2 strain within a few minutes.

Regulation of Hormonal Control, Cell Reprogramming, and Patterning during De Novo Root Organogenesis.

Body regeneration through formation of new organs is a major question in developmental biology. We investigated de novo root formation using whole leaves of Arabidopsis (). Our results show that local cytokinin biosynthesis and auxin biosynthesis in the leaf blade followed by auxin long-distance transport to the petiole leads to proliferation of J0121-marked xylem-associated tissues and others through signaling of INDOLE-3-ACETIC ACID INDUCIBLE28 (IAA28), CRANE (IAA18), WOODEN LEG, and ARABIDOPSIS RESPONSE REGULATORS1 (ARR1), ARR10, and ARR12.

Venous thromboembolism in radiation therapy cancer patients: Findings from the RIETE registry.

Background: Cancer patients are at high risk of venous thromboembolism, particularly during cancer treatment. Conversely to chemotherapy, data on the epidemiology and clinical features of venous thromboembolism during radiation therapy are scarce. There is lack of evidence on the influence of radiation therapy (RT) on outcome in cancer patients with acute venous thromboembolism (VTE).

Safety and efficacy of splenectomy in over 65-yrs-old patients with immune thrombocytopenia.

Aim: Few studies specifically focus on elderly splenectomized immune thrombocytopenia (ITP) patients. Older patients with ITP and excellent health are often excluded from surgery splenectomy. We aimed to compare the safety and efficacy of splenectomy in elderly and non-elderly ITP patients and to examine the effect of age on therapeutic response.

Documentation of acute rise in ventricular capture thresholds associated with flecainide acetate.

Treatment of paroxysmal atrial fibrillation with flecainide acetate resulted in a 4-fold increase in ventricular capture thresholds. The detailed time course of the threshold increase and decrease was documented using the AutoCapture algorithm and graphic summary.
