STARPROBE: Scientific rationale
The scientific rationale and instrumentation problems in the areas of solar internal dynamics and relativity, solar plasma and particle dynamics, and solar atmosphere structure were studied. Current STARPROBE mission and system design concepts are summarized
Lymph nodes go with the flow
In this issue, Bovay et al. (https://doi.org/10.1084/jem.20180217) invoke a compelling model of interplay between the venous and lymphatic vasculature in regulating the developmental genesis and early expansion of LNs. This work supports an emerging model that lymph-venous crosstalk supports LN functionality at all stages
Computational Fluid Dynamics Applied to Transport Systems in Trees
Our ecosystem is dependent upon the ability of photosynthetic plants to convert solar energy into a form of energy useable to biological organisms. Even so, much remains to become understood about how plants function. With such expansive bodies,how do trees cyclewaterand nutrients throughouttheir bodies

Restoring Functional Status: A Long-Term Case Report of Severe Lung and Ventilatory Muscle Pump Dysfunction Involving Recurrent Bacterial Pneumonias
Background and Purpose: Prolonged mechanical ventilation contributes to immobility and deconditioning making efforts to safely discontinue ventilator support desirable. This case report documents how implementing physical therapy treatment interventions, based on the Guide to Physical Therapist Practice, can help to restore a person’s functional status even after multiple years of mechanical ventilation dependency. Case Description: A patient (female; aged 63 years) with severe restrictive and obstructive ventilatory impairment has survived 34 recurrent pneumonias involving 6 bacterial pathogens while being mechanically ventilated at home. A 3-year study was approved and informed consent obtained for a home exercise program of resistive extremity and inspiratory muscle training along with exercise reconditioning. Tolerable distances walked, maximal inspiratory and expiratory pressures, hours spent on versus off mechanical ventilation, activities performed within and around her home, and community excursions taken were charted. Outcomes: Daily time tolerated off the ventilator improved from less than one to 12 hours, distance walked in 6 minutes increased 33%, and maximal inspiratory and expiratory pressures improved 62% and 9.6% respectively. These improvements made out-of-home social excursions possible. Discussion and Conclusions: This patient’s functional status improved following multiple physical therapy interventions dictated by the evaluation of initial physical therapy examination findings according to the Guide to Physical Therapist Practice. Long term mechanical ventilator dependency in the home environment did not exclude this patient from achieving clinically significant gains in functional status even when having severe restrictive and obstructive ventilator impairment
Macrophages in Marseille
Immunology has recently witnessed several new developments in understanding the biology of macrophages. These exciting developments were the focus of a conference in Marseille, France, in January 2013. This conference is summarized here
