Background: Different types of textile are used for the preparation of covers for bed encasement. The aim of the present study was to evaluate different fabrics employed for mattress covers regarding their efficacy in blocking Der p 1 and Fel d 1 as well as their air permeability.
Methods: Eleven different commercially available fabrics manufactured for allergen avoidance have been tested and compared with regular cotton. Dust samples titered for Der p 1 and Fel d 1 were pulled through the different fabrics using a modified Fussnecker dust trap and collected by a filter located downstream. Airflow through the dust trap was controlled by a vacuum pump operating for 5 min and measured at the beginning (T0) and at the end (T1) of the test.
Results: All the tightly woven and laminated materials were able to control mite allergen permeability allowing air passage but they significantly differed in Fel d 1 permeability. Laminated tissues and laminated tissue not tissued were effective in controlling both the allergens but they did not allow air permeability.
Conclusions: Detailed knowledge about the actual properties of the products for bed encasement needs to be considered in order to optimize allergen avoidance, disease control and sleep comfort.

Soil reinforcement is one of the techniques used to enhance the engineer characteristics of the soil. Various techniques can be employed to stabilise problematic soils, such as soft clay. These include the utilisation of portland cement, lime, fly ash, ground freezing, jet grouting, prefabricated vertical drains, and thermal approaches.

A Society of Abdominal Radiology (SAR) Pancreatic Ductal Adenocarcinoma (PDAC) Disease-Focused Panel (DFP) consensus statement described findings suspicious for local recurrence (LR) on surveillance imaging after PDAC resection. The purpose of this study was to evaluate interreader agreement and predictive utility of potential imaging findings of LR on serial surveillance CT examinations after the Whipple procedure for PDAC, using the SAR PDAC DFP consensus statement. This retrospective study included 126 patients (mean age, 68.

We demonstrate that the sessile tunicate Botryllus schlosseri is remarkably resilient to applied loads by attaching the animals to an extensile substrate subjected to quasistatic equiradial loads. Animals can withstand radial extension of the substrate to strain values as high as 20% before they spontaneously detach. In the small to moderate strain regime, we found no relationship between the dynamic size of the external vascular bed and the magnitude of applied stretch, despite known force sensitivities of the vascular tissue at the cellular level.

Ancient fluvial deposits typically display repetitive changes in their depositional architecture such as alternating intervals of coarse-grained highly amalgamated (HA), laterally-stacked, channel bodies, and finer-grained less amalgamated (LA), vertically-stacked, channels encased in floodplain deposits. Such patterns are usually ascribed to slower, respectively higher, rates of base level rise (accommodation). However, "upstream" factors such as water discharge and sediment flux also play a potential role in determining stratigraphic architecture, yet this possibility has never been tested despite the recent advances in the field of palaeohydraulic reconstructions from fluvial accumulations.

Allergen exposure is associated with the development of allergen-specific sensitization, but their relationship is influenced by other contemporaneous exposures (such as microbial exposure) and the genetic predisposition of the host. Clinical outcomes of the primary prevention studies that tested the effectiveness of allergen avoidance in pregnancy and early life on the subsequent development of sensitization and asthma published to date are inconsistent. Therefore, we cannot provide any evidence-based advice on the use of allergen avoidance for the primary prevention of these conditions.
