A computational study on the BN-yne sheet application in the Na-ion batteries.

Although Li-ion batteries are extensively applied, short lifetime, high cost, and safety problems limit their application. Na-ion batteries (NIB) might be an alternative to the Li-ion owing to wide availability, low cost, and nontoxicity of Na. Here, we performed density functional theory calculations to investigate the possible application of a graphyne-like BN layer (BN-yne) in the anode of NIBs.

Primary squamous cell carcinoma of the breast in association with Zuska's disease.

Breast cancer is the most common malignancy in women in the UK with well-defined algorithms of management in place in the western world. Squamous cell carcinoma of the breast is a rare entity and as such knowledge about the pathophysiology, treatment and prognosis are still uncertain. The report describes an unusual case of squamous cell carcinoma arising in an area of Zuska's disease of the breast.

Idiopathic eosinophilic myositis associated with vasculitis and symmetrical polyneuropathy.

We present a 79-yr-old white woman admitted to the hospital with diffuse myalgias and muscle weakness associated with eosinophilia. Examination of a muscle biopsy section revealed eosinophilic myositis with vasculitis. This association is infrequent and we describe the first case report with symmetrical polyneuropathy.
