First Report of Bacterial Pineapple Heart Rot Caused by in Puerto Rico.

In Puerto Rico, the agricultural production of pineapple ( (L.) Merr.) comprises nearly 5,000 tons harvested annually from over 250 ha (USDA 2018).

Invasion windows for a global legume invader are revealed after joint examination of abiotic and biotic filters.

Successful alien plant invasion is influenced by both climate change and plant-plant interactions. We estimate the single and interactive effects of competition and extreme weather events on the performance of the global legume invader Lupinus polyphyllus (Lindl.).

Thulium-YAG laser sialendoscopy for parotid and submandibular sialolithiasis.

Objective: To evaluate the efficacy and safety of thulium-YAG laser in sialendoscopic fragmentation of salivary lithiasis.

Design: Retrospective, interventional case series.

Material: Sixty-three patients treated by interventional sialendoscopy with thulium-Yag laser fragmentation between 2003 and 2010 at Edouard Herriot Hospital were included in the study.

Quantitative image analysis of vertebral body architecture--improved diagnosis in osteoporosis based on high-resolution computed tomography.

71 women, 64 post-menopausal, were examined by single-energy quantitative computed tomography (SEQCT) and by high-resolution computed tomography (HRCT) scans through the middle of lumbar vertebral bodies. Computer-assisted image analysis of the high-resolution images assessed trabecular morphometry of the vertebral spongiosa texture. Texture parameters differed in women with and without age-reduced bone density, and in the former group also in patients with and without vertebral fractures.

CT and MR features of primary pulmonary hemangiopericytomas.

We investigated the radiological findings of four patients with malignant pulmonary hemangiopericytomas, comparing plain chest radiography, CT, and MR. The radiographic presentation ranged from a small single lesion to a tumor almost completely occupying a hemithorax. Pathognomonic radiological features of malignant pulmonary hemangiopericytomas could not be established, but characteristic features include a large lobulated well-circumscribed mass with an encapsulated appearance, contrast enhancement of the margin, and no signs of surrounding compression atelectasis.
