Enhancement of Meniscus Pump by Multiple Particles.

We numerically investigate the behavior of a droplet spreading on a smooth substrate with multiple obstacles. As experimental works have indicated, the macroscopic contact line or the three-phase boundary line of a droplet exhibits significant deformation resulting in a local acceleration by successive interactions with an array of tiny obstacles settled on the substrate (Mu et al., ).

[Mediastinal Shift Due to the Rapidly Expanded Giant Bulla Probably Caused by the Lung Cancer].

A 39-year-old man was admitted to our hospital with back pain and numbness of the left leg. Computed tomography (CT) showed a giant bulla and tumor in the right lung, mediastinal shift to the left side and lesions suggestive of metastatic sacral tumor. Three days later, the patient visited the emergency room with dyspnea and tachycardia.

Pumping effect of heterogeneous meniscus formed around spherical particle.

Hypothesis: A disturbance such as a microparticle on the pathway of a spreading droplet has shown the tremendous ability to accelerate locally the motion of the macroscopic contact line (Mu et al., 2017). Although this ability has been linked to the particle-liquid interaction, the physical mechanisms behind it are still poorly understood despite its academic interest and the scope of numerous industrial applications in need of fast wetting.

Oxidized regenerated cellulose for a clear thoracoscopic view: a single-centre randomized trial.

Objectives: During video-assisted thoracoscopic surgery (VATS), blood oozing from the surface of the access port wound can hamper the surgical view. Although this oozing is difficult to prevent, it can be decreased by placing a wound edge protector with oxidized regenerated cellulose (ORC) on the surface of the access port wound, thereby improving the surgical outcomes and safety of VATS.

Methods: We conducted a prospective, single-centre, open-label, randomized clinical trial to evaluate the operative outcomes of VATS when using the ORC (ORC group) compared with operative outcomes without using the ORC (non-ORC group).

A novel EWSR1-VGLL1 gene fusion in a soft tissue malignant myoepithelial tumor.

Soft tissue myoepithelial tumors are very rare mesenchymal tumors that are currently categorized as miscellaneous neoplasms with uncertain differentiation. Although the molecular pathogenesis of soft tissue myoepithelial tumors remains unclear, EWSR1 gene fusions with a variety of partner genes are regarded as one of the major pathogenic driver events in these tumors. We herein present a case of a deep soft tissue malignant myoepithelial tumor arising in the thigh with multiple pulmonary metastases.

[Successful Treatment of a Patient with Idiopathic Subglottic Stenosis].

Idiopathic subglottic stenosis (ISS) is defined as the narrowing of the upper airway without any known cause. A 40-year-old female was referred to our hospital with the complaint of exacerbation of dyspnea causing difficulty in going out. Chest computed tomography (CT) scan and bronchoscopy revealed subglottic tracheal stenosis with a luminal diameter of 5 mm at the narrowest part.
