Peripheral neuropathy in stable chronic obstructive pulmonary disease: Is the phrenic nerve more affected compared with other peripheral nerves?

Al-Azhar Assiut Medical Journal, 2017
Background Chronic obstructive pulmonary disease (COPD) is a multicomponent disease with extrapulmonary manifestation. Peripheral nerve affection may be one of the results or mechanism of COPD. Objective The aim of this study was to evaluate peripheral

Endometriosis of Diaphragm: A Case Report [PDF]

International Journal of Fertility and Sterility, 2018
Endometriosis affects about 10% of women of reproductive age. Its main feature is the presence of stroma and endometrial glands in sites other than the uterus, mainly in pelvis. Pelvic peritoneum, ovaries, uterine ligaments, bladder, intestines, andcul-

Folding Energetics in Thin-Film Diaphragms [PDF]

arXiv, 2000
We perform experiments on thin-film diaphragms to show that the folding patterns of anisotropically compressed diaphragms are strikingly different from those of isotropically compressed ones. We then use a simple von Karman model to relate the overall features of these folding patterns to the underlying energetics.

Anti‐icing Performance of Superhydrophobic Surfaces with Periodic Micro‐nano Structures Directly Induced by Femtosecond Laser

Advanced Materials Interfaces, EarlyView.
This study provides a femtosecond laser etching method for preparing superhydrophobic anti‐icing surfaces, which directly induces periodic micro‐nano structures on the laser scanning path, eliminating the complicated steps of designing hydrophobic patterns.

Diaphragm recovery by laryngeal innervation after bilateral phrenicotomy or complete C2 spinal section in rats

Neurobiology of Disease, 2006
This study aimed to highlight the functional aspects of diaphragm reinnervation by laryngeal motoneurons after bilateral phrenicotomy or complete cervical transection. The left recurrent laryngeal nerve was connected to the left phrenic nerve in 14 rats.

Development and Application of a Diaphragm Micro-Pump with Piezoelectric Device [PDF]

Dans Symposium on Design, Test, Integration and Packaging of MEMS/MOEMS - DTIP 2007, Stresa, lago Maggiore : Italie (2007), 2008
In this study, a new type of thin, compact, and light weighed diaphragm micro-pump has been successfully developed to actuate the liquid by the vibration of a diaphragm. The micro-diaphragm pump with two valves is fabricated in an aluminum case by using highly accurate CNC machine, and the cross-section dimension is 5mm x 8mm. Both valves and diaphragm
