Diffuse alveolar damage (DAD) is a histological change in lung tissue, and is generally caused by an acute lung injury, which is characterized by bilateral and widespread damages. Localized DAD occurs very rarely. The causes for DAD are numerous, but the chief cause is acute interstitial pneumonia or acute exacerbation of idiopathic interstitial pneumonia, in cases of idiopathic manifestation. ...

Xanthii Fructus (XF), the fruit of Xanthium sibiricum Patr., was used in the treatment of rhinitis and related nasal disease. Adverse effects of Xanthii Fructus are frequently reported these years. In the paper, in vitro renal cytotoxicity and in vivo acute and chronic toxicity researches of Xanthii Fructus (XF) and its processed product (processed Xanthii Fructus (PXF)) were carried out. Water...

A reverse phase ultra performance liquid chromatography and photodiode array (UPLC-PDA) detection method was established for the determination of six alkaloids in Zoagumhwan (ZGW), and further for investigating the influence of nonpolar substances on the extraction efficiency of these alkaloids. The method was based on a BEH C(18) (50 mm × 2.1 mm, 1.7 μm) column and mobile phase of aqueous phos...

Mammalian and fungal Diaphanous-related formin homology (DRF) proteins contain several regions of conserved sequence homology. These include an amino-terminal GTPase binding domain (GBD) that interacts with activated Rho family members and formin homology domains that mediate targeting or interactions with signaling kinases and actin-binding proteins. DRFs also contain a conserved Dia-autoregul...

Gleditsiae Fructus Abnormalis and Gleditsiae Sinensis Fructus are obtained from different developmental stages of fruits from Gleditsia sinensis Lam. (Leguminosae). The possible interchangeable usage of the two fruits, however, has long been very controversial. Here, high performance liquid chromatography coupled with diode array detection was developed to explore their chemical fingerprinting ...

During a layer-3 handoff, address acquisition via DHCP is often the dominant source of handoff delay, duplicate address detection (DAD) being responsible for most of the delay. We propose a new DAD algorithm, passive DAD (pDAD), which we show to be effective, yet introduce only a few milliseconds of delay. Unlike traditional DAD, pDAD also detects the unauthorized use of an IP address before it...

Duplicate address detection (DAD) is an important component of the address resolution protocol (ARP) and the neighbor discovery protocol (NDP). DAD determines whether an IP address is in conflict with other nodes. In traditional DAD, the target address to be detected is broadcast through the network, which provides convenience for malicious nodes to attack. A malicious node can send a spoofing ...

INTRODUCTION Diffuse alveolar damage (DAD) is the pathological hallmark of acute respiratory distress syndrome (ARDS), however, the presence of DAD in the clinical criteria of ARDS patients by Berlin definition is little known. This study is designed to investigate the role of DAD in ARDS patients who underwent open lung biopsy. METHODS We retrospectively reviewed all ARDS patients who met th...
