This document defines a DTLS tunneling protocol for use in multimedia |
conferences that enables a Media Distributor to facilitate key |
exchange between an endpoint in a conference and the Key Distributor. |
The protocol is designed to ensure that the keying material used for |
hop-by-hop encryption and authentication is accessible to the media |
distributor, while the keying material used for end-to-end encryption |
and authentication is inaccessible to the media distributor.Safety of a home exercise programme in patients with polymyositis and dermatomyositis: a pilot study. |
OBJECTIVES |
To investigate whether a home exercise programme could safely be performed by patients with stable, inactive polymyositis (PM) and dermatomyositis (DM), regarding disease activity, muscle function, health status and pain. |
METHODS |
Ten patients with reduced muscle function completed the study. A home exercise programme including exercises for strength in the upper and lower limbs, neck and trunk, for mobility in the upper limbs and moderate stretching was developed. The patients exercised for 15 min and took a 15 min walk 5 days a week during a 1... |
RESULTS |
After 12 weeks of exercise, there were no signs of increased disease activity as assessed clinically, by CPK values, MRI or muscle biopsy findings. On an individual basis, all patients improved regarding muscle function according to the FI, in six cases the improvement reached statistical significance (P < 0.05). A sig... |
CONCLUSIONS |
Our results indicate that this home exercise programme can be safely employed in patients with stable, inactive PM and DM, with beneficial effects on muscle function.Seed germination and phytochemical evaluation in seedlings of Aloe arborescens Mill. |
Many Aloe species are exploited as natural products. Generally, the leaves are unsustainably picked from wild plants to meet the market demand. Basic scientific information on seed biology and the ways of increasing levels of secondary metabolites in seedlings is still lacking for Aloe species. This study investigated ... |
We tested the hypothesis that a combination of angiotensin-converting enzyme inhibitor (ACEi) and angiotensin II type 1 receptor antagonist (AT1-ant) may have an additive cardioprotective effect in mice with heart failure (HF), because these two agents could have other mechanisms of action besides interrupting the reni... |
The tectonic nature of the fields of the Nepa-Botuoba anteclise is considered within the framework of the fluid-dynamic concept. The main element of this concept is basin-forming activated fault systems with the properties of cyclic manifestation, direction of generation, time and period of activation. It has been esta... |
The paper summarizes a maneuvering target tracking using a tracking filter with constant velocity and constant angular velocity model. A constant velocity model or a constant acceleration model is often used as a dynamic model of a tracking filter. If a target turns, these filters can not give full performance due to t... |
Bacteria are highly interactive and possess an extraordinary repertoire of intercellular communication and social behaviors, including quorum sensing (QS). QS has been studied in detail at the molecular level, so mechanistic details are well understood in many species and are often involved in virulence. The use of dif... |
Fourier ptychographic microscopy (FPM) is a new computational super-resolution approach, which can obtain not only the correct object function, but also the pupil aberration, the LED misalignment, and beyond. Although many state-mixed FPM techniques have been proposed to achieve higher data acquisition efficiency and r... |

In standard teletherapy, a treatment plan is generated with the aid of a treatment planning system, but it is common to perform an independent monitor unit verification calculation (MUVC). In exact analogy, we propose and demonstrate that a simple and accurate MUVC in intensity modulated radiotherapy (IMRT) is possible... |
The authors studied length-of-stay and readmission rates in Missouri's five state mental hospitals, attempting to control for diagnosis and patient-to-patient differences in chronicity. Each hospital's ratings were ranked by diagnostic category, and the data show that hospitals with short lengths of stay tended to have... |
OBJECTIVES |
To identify associations between use of ipratropium and/or intravenous magnesium and outcomes of children hospitalized with acute asthma exacerbations and treated with continuous albuterol. |
METHODS |
Secondary analysis of data from children prospectively enrolled in the multicenter Ohio Pediatric Asthma Repository restricted to only children who were treated with continuous albuterol in their initial inpatient location. Children were treated with adjunctive therapies per the clinical team. |
RESULTS |
Among 242 children who received continuous albuterol, 94 (39%) received ipratropium only, 13 (5%) received magnesium alone, 42 (17%) received both, and 93 (38%) received neither. The median duration of continuous albuterol was 7.0 (interquartile range [IQR]: 2.8-12.0) hours. Ipratropium use was associated with a shorte... |
CONCLUSIONS |
Ipratropium and magnesium were both often used in children with severe asthma hospitalizations that required continuous albuterol therapy. Magnesium use was associated with unfavorable outcomes, possibly reflecting preferential treatment to patients with more severe cases and differing practices between centers. Given ... |
