BACKGROUND Vibration response imaging (VRI) is a novel imaging technique and little is known about its characteristics and diagnostic value in idiopathic pulmonary fibrosis (IPF). The aim of this study was to investigate the features of VRI in subjects with IPF. METHODS We enrolled 23 subjects with IPF (42-74 y old) and 28 healthy subjects (42-72 y old). Subjects with IPF were diagnosed by lu...

Amphiuma red cells were incubated for several hours in hypotonic or hypertonic media. They regulate their volume in both media by using ouabain-insensitive salt transport mechanisms. After initially enlarging osmotically, cells in hypotonic media return toward their original size by losing K, Cl, and H2O. During this volume-regulatory decrease (VRD) response, K loss results from a greater than ...

BACKGROUND AND OBJECTIVES A variety of methods have been used to evaluate patients with lung cancer to define a patient cohort at high risk for postoperative mortality and respiratory complications associated with lung resection surgery. Our aim was to evaluate the utility of vibration response imaging (VRI(XP)) Operation Planning Software (O-Plan) in assessing suitability for surgical resectio...

BACKGROUND Predicting postoperative lung function is important for estimating the risk of complications and long-term disability after pulmonary resection. We investigated the capability of vibration response imaging (VRI) as an alternative to lung scintigraphy for prediction of postoperative lung function in patients with intrathoracic malignancies. METHODS Eighty-five patients with intratho...

in clinical management of singers it’s important to identify risk components of vocal fatigue and glottic damage, predicting and assessing the vocal cost of the various vocal performances to avoid any risk. despite many difficulties, we made dosimetries on singers (9 opera and 9 musical) during live theatre performances. our aim was to evaluate phonatory behaviours before, during and after perf...

Comparisons of variable rate irrigation (VRI) and fertigation (VRF) with fixed (FRI), no (NI) conventional fertilizer management for maize (Zea mays L.) under three soil types (S1, S2 S3) were made years (2015, 2016 2017). The research quantified compared growth development [leaf area index (LAI) plant height], grain yield, crop evapotranspiration (ETc), irrigation-yield production functions (I...

The Drosophila circadian clock consists of two interlocked transcriptional feedback loops. In one loop, dCLOCK/CYCLE activates period expression, and PERIOD protein then inhibits dCLOCK/CYCLE activity. dClock is also rhythmically transcribed, but its regulators are unknown. vrille (vri) and Par Domain Protein 1 (Pdp1) encode related transcription factors whose expression is directly activated b...

Increased abdominal muscle wall activity may be part of a visceromotor reflex (VMR) response to noxious stimulation of the bladder. However, information is sparse regarding the effects of cauda equina injuries on the VMR in experimental models. We studied the effects of a unilateral L6-S1 ventral root avulsion (VRA) injury and acute ventral root reimplantation (VRI) into the spinal cord on mict...

OBJECTIVE To examine the influence of viral respiratory infection (VRI) on treatment response in acute asthma in children. STUDY DESIGN A total of 218 children (mean age, 6.6 years) with acute asthma were recruited. Symptoms were recorded, an asthma severity score was determined, and whenever possible, a per-nasal aspirate was obtained for detection of viruses. Each child's response to inhale...

Vri is closely related to bZIP transcription factors involved in growth or cell death. vri clonal and overexpression analyses revealed defects at the cellular level. vri clones in the adult cuticle contain smaller cells with atrophic bristles. The phenotypes are strictly cell autonomous. Clones induced in the eye precursor cells lead to individuals with smaller eyes and reduced number of ommati...
