Giant air cysts of the lung were found in 6 of 180 patients admitted to the hospital with spontaneous pneumothorax. The preoperative diagnosis was established in all the patients on the basis of their past history, clinical course, X-ray examination and puncture of the pleural cavity. The operative treatment of cysts of the lung is recommended. All the 6 patients were operated upon with good results (in 3 patients--lobectomy, cysts were removed in 3 patients).

Background: Giant hydronephrosis as an rare condition is often caused by chronic ureteral obstruction. Nephroplication is a crucial procedure to improve urinary drainage in the kidney-sparing surgery for patients with giant hydronephrosis. However, traditional nephroplication via suturing kidney has technical difficulty and many potential risks.

For large, open-air lithic cultural heritage, colonization is an inevitable process. This study examines the dual impact of colonization on the Leshan Giant Buddha's sandstone monuments, focusing on both biodeterioration and protection. Over three years, we conducted field surveys and monitored biocrusts (bryophytes, lichens, and biofilms) on these monuments, observing significant biodeterioration primarily due to mechanical exfoliation and acid corrosion.

Pulmonary sclerosing pneumocytoma is a rare benign neoplasm typically seen in middle-aged women. The exact preoperative diagnosis is quite challenging considering its nonspecific clinical and radiologic features along with complex histology. Moreover, obtaining an exact histopathological diagnosis can be difficult especially with the small biopsy specimens.

Dielectric metasurfaces open new avenues in nonlinear optics through their remarkable capability of boosting frequency conversion efficiency of nonlinear optical interactions. Here, a metasurface consisting of a square array of cruciform-shaped silicon building blocks covered by a monolayer MoS is proposed. By designing the metasurface so that it supports optical bound states in the continuum (BICs) at the fundamental frequency and second harmonic, nearly 600× enhancement of the second-harmonic generation (SHG) in the MoS monolayer as compared to that of the same MoS monolayer suspended in air is achieved.
