Pneumothorax with Bullous Lesions as a Late Complication of Covid-19 Pneumonia: A Report on Two Clinical Cases.

Background: Coronavirus-19 disease (COVID-19) primarily affects the respiratory tract, causing viral pneumonia with fever, hypoxemia, and cough. Commonly observed complications include acute respiratory failure, liver or kidney injury, and cardiovascular or neurologic symptoms. In some patients, inflammatory damage results in long-term complications, such as pulmonary fibrosis, chronic pulmonary thrombotic microangiopathy, or neurologic symptoms.

Coronavirus disease (COVID-19): observations and lessons from primary medical care at a German community hospital.

The pandemic outbreak of COVID-19 challenges medical care systems all around the world. We here describe our experiences during the treatment of COVID-19 patients (n = 42) treated from 2 March 2020 to 16 April 2020 at a German district hospital. Forty-two COVID-19 patients were hospitalized and five patients developed a severe disease, requiring intensive care.

RAPTOR Controls Developmental Growth Transitions by Altering the Hormonal and Metabolic Balance.

Vegetative growth requires the systemic coordination of numerous cellular processes, which are controlled by regulatory proteins that monitor extracellular and intracellular cues and translate them into growth decisions. In eukaryotes, one of the central factors regulating growth is the serine/threonine protein kinase Target of Rapamycin (TOR), which forms complexes with regulatory proteins. To understand the function of one such regulatory protein, Regulatory-Associated Protein of TOR 1B (RAPTOR1B), in plants, we analyzed the effect of mutations on growth and physiology in Arabidopsis () by detailed phenotyping, metabolomic, lipidomic, and proteomic analyses.

Control of plant leaf movements by the lunisolar tidal force.

Background: Investigations into the diurnal ascent and descent of leaves of beans and other species, as well as experimental interventions into these movements, such as exposures to light at different times during the movement cycle, led to the concept of an endogenous 'clock' as a regulator of these oscillations. The causal origin of leaf movement can be traced to processes that modulate cell volume in target tissues of the pulvinus and petiole. However, these elements of the leaf-movement process do not sufficiently account for the rhythms that are generated following germination in constant light or dark conditions, or when plants are transferred to similar free-running conditions.
