BACKGROUND Transverse nasal crease is an uncommonly reported entity. It likely represents an embryologic fault line. Transverse nasal milia have also been reported in the same location, both as an isolated finding and in a transverse nasal crease. This observation suggests they are variants of the same entity. OBSERVATIONS Two cases, one of transverse nasal crease with milia and one of transv...
Background and Objective: The most used dyes in textile industries are Azo Group dyes. Azo dyes have complex aromatic compounds, low chemical and biodegradable stability. Due to these properties, treatment of this type of wastewater by conventional methods will not meet environmental standards. The advanced oxidation process has been widely used to treat organic matter from wastewater. In this ...
The effect of epinephrine on neutrophil (PMN) kinetics in rabbit lungs was evaluated by measuring the retention of radiolabeled PMN's in the lung, the exchange rate between the marginated and circulating pools of PMN's, and the erythrocyte (RBC) transit time. Epinephrine treatment decreased RBC transit times and increased exchange rates in the regions with the shortest transit times but did not...
Two groups of Clark’s nutcrackers (Nucifraga columbiana) were trained to use either a stay or shift response strategy in a radial maze analogue. Each trial had a preretention stage, a retention interval, and a postretention test. In Experiment 1, acquisition with a 5-min retention interval was studied. Response strategy did not affect the rate at which the task was learned. Performance followin...

We investigated the effects of grade retention in first grade on the growth of the Woodcock-Johnson broad mathematics and reading scores over three years using linear growth curve modeling on an academically at-risk sample. A large sample (n=784) of first grade children who were at risk for retention was initially identified based on low literacy scores. Scores representing propensity for reten...
Three experiments investigated the acquisition and retention of structural and object landmarks in virtual indoor environments. The experiments investigated the rate of acquisition and memory retention for hallway structure (structural landmarks) and pictures (object landmarks). The experiments investigated the rate of acquisition, the role of information content, and memory retention of this i...
The purposes of this article are: (a) to describe and analyze the accrual and retention patterns in a longitudinal randomized clinical trial with prostate cancer patients and their partners, and (b) to discuss strategies that were used to overcome challenges in conducting this family-based study. Initially, 429 dyads were referred to the study. Of these, 166 were not enrolled due to refusal (n ...
To evaluate the efficacy and safety of plasmakinetic resection of the prostate (PKRP) versus transurethral resection of the prostate (TURP) for the treatment of patients with benign prostate hyperplasia (BPH), a meta-analysis of randomized controlled trials was carried out. We searched PubMed, Embase, Web of Science and the Cochrane Library. The pooled estimates of maximum flow rate, Internatio...
Abstract Effects of egg retention on movement and dispersal activity of Trichogramma principium (Hymenoptera, Trichogrammatidae) females were investigated under laboratory conditions. Individual females were observed during one minute in the absence of hosts. Movement activity and dispersal rate were estimated by the length of the track and by the distance from the start point, respectively. Be...
