Contributing Factors in Whether Displaced Households Want to Receive Humanitarian Information from Humanitarian Actors: Iraq Multi-Cluster Needs Assessment.

Due to political conflict, insurgency, and the COVID-19, the number of displaced households in need of humanitarian support in Iraq has increased. This study investigated factors related to desire of displaced households to receive humanitarian information. Data from the eighth round of the Iraq Multi-Cluster Needs Assessment was used.

Inhibitory effect of procyanidin oligomer from elm cortex on the matrix metalloproteinases and proteases of periodontopathogens.

Objectives: The purpose of this study was to evaluate a partially purified extract (elm extract) from the Ulmi cortex (Ulmi macrocarpa Hance) and its active ingredient, a mix of procyanidin oligomers (3 to 12 flavan-3-ol monomers, an average molecular weight of 1,518 with an average polymerization degree of 5.3) for a possible inhibitory effect against proteases.

Background: Host-derived matrix metalloproteinases (MMPs) and bacterial proteases play important roles in the gingival tissue destruction that is a characteristic of periodontitis.
