“We measure the lasing dynamics of single and coupled photonic crystal nanocavity array lasers fabricated in the indium gallium arsenide phosphide material system. Under short optical excitation, single cavity lasers produce pulses
as fast as 11 ps (full width at half maximum), while coupled cavity lasers show significantly longer lasing duration which is not explained by a simple rate equation model. A finite difference time domain simulation including carrier gain and diffusion suggests that asynchronous lasing across the nanocavity array extends the laser’s pulse duration.

“Objective: Anxiety disorders have been shown to undermine the quality of life of cancer patients. Unfortunately, medical professionals often neglect to screen for anxiety in their patients. The aim of the present study was to describe the prevalence of anxiety in patients awaiting diagnostic procedures in an oncology center waiting room, and to investigate possible relationships between anxiety and demographic and clinical variables.
Methods: A cross-sectional study was performed with 398 patients who completed a self-administered questionnaire this website containing
the Hospital Anxiety and Depression Scale (HADS) and the State-Trait Anxiety Inventory (STAI).
Results: Results of the HADS indicated that 38% of participants had anxiety, while data from the STAI showed that 46% had either high state or trait anxiety. The most frequently cited source of anxiety was concern over test results. selleck chemicals Age, gender, employment status, and education level were correlated with anxiety.
Conclusions: The prevalence of anxiety is high among patients awaiting diagnostic procedures. Patients in the waiting room should be routinely screened for anxiety. Careful assessment and treatment of anxiety are important
components in the care of patients with cancer. Copyright (C) 2010 John Wiley & Sons, Ltd.”
“Purpose: We identify the expression of PRL-3 in primary endometrioid endometrial cancer and metastases in relation to the clinicopathological characteristics.
Material/Methods: The study involved 30 patients with type I endometrial cancer. Twelve of them were diagnosed with metastases in various localization of abdomen. The PRL-3 expression was evaluated on the basis of immunohistochemistry results by the use of monoclonal antibody anti-PRL3 clone 3B6.
Results: The intensity of PRL-3 expression in correlation with tumor stage was statistically significant (p = 0.024). The strongest reaction was noted in cases classified as a 1a and 1b stage defined by FIGO. The strength of PRL-3 expression is significantly associated with the degree of histological tumor grade (p = 0.035).
