College of Life Science, Henan Agricultural University, Zhengzhou, China.
Background: Assessing the current status and identifying the mechanisms threatening endangered plants are significant challenges and fundamental to biodiversity conservation, particularly for protecting Tertiary relict trees and plant species with extremely small populations (PSESP). Ulmus elongata (Ulmus, Ulmaceae) with high values for the ornamental application, is a Tertiary relict tree species and one of the members from PSESP in China. Currently, the wild populations of U.

The alteration of neurovascular coupling (NVC), where acute localized blood flow increases following neural activity, plays a key role in several neurovascular processes including aging and neurodegeneration. While not equivalent to NVC, the coupling between simultaneously measured cerebral blood flow (CBF) with arterial spin labeling (ASL) and blood oxygenation dependent (BOLD) signals, can also be affected. Moreover, the acquisition of BOLD data allows the assessment of resting state (RS) fMRI metrics.

Department of Statistics, Purdue University, Mathematical Sciences Building, 150 N. University Street, Room 231, West Lafayette, IN 47907.
Background: Methods to elicit the vital capacity (VC) include forced vital capacity (FVC) and slow vital capacity (SVC). Because the FVC maneuver can be affected by air trapping or inefficiencies in lung emptying vs. the SVC, the SVC-FVC difference may be substantial and diagnostically meaningful in elderly individuals and patients with respiratory obstruction.

Department of Hematology, Suita Municipal Hospital, Japan.
A 51-year-old woman with persistent proliferation of natural killer (NK) cells in her peripheral blood was diagnosed with NK-large granular lymphocytic leukemia (NK-LGLL). During follow-up, computed tomography revealed multiple infiltrative pulmonary lesions. A flow cytometric analysis of bronchoalveolar lavage fluid showed infiltration of NK cells, resulting in a diagnosis of pulmonary infiltration by NK-LGLL.

Department of Comprehensive Dentistry, UT Health San Antonio, San Antonio, USA.
Purpose: To determine the effects of K18 quaternary ammonium methacryloxy silane (QAS) on tissue conditioner materials and their antimicrobial properties.
Methods: 30% K18 QAS in methyl methacrylate (MMA; K18-MMA; 0%, 15%, and 20% w/w) was incorporated into a commercial tissue conditioner (Coe comfort). The degree of curing (Shore A hardness), hydrophilicity (contact angle), flow, liquid sorption, mass loss, and antimicrobial properties of Streptococcus mutans, Streptococcus sanguinis, and Candida albicans were determined.
