CLINICAL EVALUATION OF PRESSURE SUPPORT VENTILATION

British Journal of Anaesthesia, 1989
A 5-year-old child required a prolonged period of ventilatory assistance, provided in the form of pressure support ventilation. There was a significant negative correlation between the level of pressure support and the PaCO2. Requirements for sedation were reduced with pressure support compared with conventional controlled ventilation.

Synchronization‐Dissipation in the Cardiorespiratory System

Advanced Science, EarlyView.
By modeling central nervous coupling and viscoelastic interactions in the cardiorespiratory system we show that synchronization produces a 10% gain in cardiac efficiency in humans. It is surmised that respiratory sinus arrhythmia improves cardiac pumping efficiency by reducing dynamic stress and power dissipation in the pulmonary vasculature.

Macrophage‐to‐Myofibroblast Transdifferentiation Contributes to Pulmonary Fibrosis via the MERTK‐SPP1‐SRC‐TKS5 Signaling Axis

Advanced Science, EarlyView.
MERTK is upregulated in fibrotic macrophages and regulates the expression and activity of SRC and TKS5 through SPP1, mediating transdifferentiation of macrophages‐to‐myofibroblasts (MMT) and promoting pulmonary fibrosis. The figure was created with BioRender.com.

Alveolar pressure during pressure support ventilation.

Nihon Shuchu Chiryo Igakukai zasshi, 1999
圧支持換気(pressure support ventilation, PSV)の設定圧が肺内でどのように伝播するかを調べるため,PSV中の肺胞圧を測定した。雑種成犬6頭をペントバルビタールで麻酔し,フジシステムズ製内径8.5mmのユニベントチューブを気管挿管した。犬を側臥位とし肋間筋を分け,「閉胸式カプセル法」によりカプセルを肺に接着し,その圧を肺胞圧とした。気管内圧はユニベントチューブのオクルージョンカテーテルより導出した。回路内圧,気管内圧および肺胞圧は圧トランスデューサで測定し,同時にポリグラフで記録した。PSVは呼気終末陽圧(PEEP)5cmH2O,立上がり時間0.5secで,設定圧5,10cmH2Oの2通りを検討した。回路内圧波形は設定圧に達するとプラトーとなったが,気管 ...

Closed‐Loop Radiative Cooling Mulch Upcycled From Agricultural Residues for Efficient Soil Heat–Water Stress Mitigation

Advanced Science, EarlyView.
Conventional passive radiative cooling films rely on costly feedstocks and energy‐intensive fabrication, with poor end‐of‐life compatibility in agriculture. To address this challenge, a sustainable radiative cooling mulch (SRCM) is developed from waste maize leaves via spontaneous hydrogen‐bond self‐assembly.

The E3 Ligase RNF115 Aggravates Pathological Cardiac Hypertrophy via Ubiquitin‐Mediated Degradation of SPTBN1

Advanced Science, EarlyView.
In response to hypertrophic stimuli, increased c‑JUN phosphorylation upregulates RNF115, leading to SPTBN1 ubiquitination and degradation. which promotes F‑actin depolymerization and YAP activation, driving cardiac hypertrophy. The RNF115 inhibitor DTD effectively suppresses SPTBN1 ubiquitination and cardiac hypertrophy.

Micro‐Galvanic Coupling Programs the Therapeutic Zinc Ion Window to Reconfigure Immune Cascades for Pro‐Regenerative Bone Healing

Advanced Science, EarlyView.
This study utilized alloy micro‐galvanic coupling design to regulate the release of essential elements, thereby programming immune responses and promoting regeneration. The sacrificial anodic process of Zn‐0.8Mg reduced Zn2+ release compared to the “large cathode‐small anode” coupling of Zn‐0.8Fe.
