Objective: To examine cancer mortality in continuous glass filament workers.
Methods: A cohort of 936 continuous glass filament workers employed in a plant from northern Italy since January 1976 was followed-up through December 2003, for a total of 19,987 man-years.
Results: Overall, 144 deaths were observed compared with 160.8 expected based on regional death rates (standardized mortality ratio [SMR] = 0.90, 95% CI = 0.76 to 1.05). There were 53 deaths from all cancers (SMR = 1.01, 95% CI = 0.75 to 1.32), and 21 from lung cancer (SMR = 1.23, 95% CI = 0.76 to 1.89). There was no consistent relation with risk for age at first employment, time since first or last employment, or duration of employment for any of the causes considered.
Conclusions: Although limited in size, this study provides no evidence that continuous glass filament workers experience a significant increased risk of cancer, including respiratory cancer.

Developing a wearable device that can continuously and reliably detect and evaluate heart rate variability (HRV) parameters is critical for the diabetic population with cardiac autonomic neuropathy (CAN). In this work, we proposed a zwitterionic conducting hydrogel that enabled a reliable and comfortable wearable device for the evaluation and detection of the autonomic nervous system (ANS). The hydrogel can achieve a strain of 2003 %, an electrical conductivity of 190 mS/m, and is capable of adhering to a variety of materials, including wood, plastic, and glass.

Aim To evaluate and compare the fracture toughness and flexural strength of interim fixed partial dentures reinforced with carbon, glass, and Kevlar nanofibers. Materials and methods This study explored the effect of reinforcing poly methyl methacrylate with carbon, glass, and Kevlar fibers on its fracture toughness and flexural strength. A total of 120 samples were prepared, divided into two groups of 60 samples each, with one group tested for fracture toughness and the other for flexural strength.

The current lack of stable, scalable, and efficient coating technology dramatically limits the exploitation of solar-driven graphitic carbon nitride (CN) photocatalysts. Herein, a unique, efficient, and scalable method is reported to immobilize CN powder on various substrates ranging from Fluorine tin oxide (FTO), glass, Plexiglas, Al foil, Ti foil, and Granite stone, to even wood. The film shows an outstanding thickness of 212 µm, which is the highest value ever reported.

Background: Robot-assisted thoracic surgery has been shown to have several advantages over conventional surgery. As mobile communication technology and surgical robotic devices in China continue to progress rapidly, the conditions for performing remote surgery have been optimized. Consequently, informatized and remote advanced medical cooperation is becoming a new direction for supporting the medical development of border regions and promoting the equitable distribution of medical resources in China.

Background: The mechanistic pathways that give rise to the extreme symptoms exhibited by rare disease patients are complex, heterogeneous, and difficult to discern. Understanding these mechanisms is critical for developing treatments that address the underlying causes of diseases rather than merely the presenting symptoms. Moreover, the same dysfunctional series of interrelated symptoms implicated in rare recessive diseases may also lead to milder and potentially preventable symptoms in carriers in the general population.
