Currently, there are few guidelines for the use of vitamin K1 in the maintenance treatment of long-acting anticoagulant rodenticide (LAAR) poisonings. We explored factors in the treatment of LAAR poisoning during the maintenance period in order to suggest feasible treatment models.Data from 24 cases of anticoagulant rodenticide poisoning in our hospital were collected from January 2013 to May 2...

Kaposi's sarcoma (KS) is an AIDS-defining cancer with aberrant neovascularization caused by KS-associated herpesvirus (KSHV). Although the interaction between HIV-1 and KSHV plays a pivotal role in promoting the aggressive manifestations of KS, the pathogenesis underlying AIDS-KS remains largely unknown. Here we examined HIV-1 Nef protein promotion of KSHV oncoprotein K1-induced angiogenesis. W...

Kaposi's sarcoma-associated herpesvirus (KSHV/HHV-8) has been linked to Kaposi's sarcoma, primary effusion lymphoma, and multicentric Castleman's disease. In addition to endothelial cells and B lymphocytes, KSHV also has been shown to infect epithelial cells and keratinocytes. The transmembrane glycoprotein K1, encoded by the first open reading frame of KSHV, is a signaling protein capable of e...

Abstract Recognition of pathogen-associated molecular patterns (PAMPs) such as flagellin, a main component of the bacterial flagellum, constitutes the first layer of plant immunity and is referred to as PAMP-triggered immunity (PTI). The rice avirulent N1141 strain of gram-negative phytopathogenic bacterium, Acidovorax avenae, induces PTI including H2O2 generation, while flagellin from the rice...

We have recently reported the identification of kringle 1-5 (K1-5) of plasminogen as a potent and specific inhibitor of angiogenesis and tumor growth. Here, we show that K1-5 bound to endothelial cell surface ATP synthase and triggered caspase-mediated endothelial cell apoptosis. Induction of endothelial apoptosis involved sequential activation of caspases-8, -9, and -3. Administration of neutr...

Kaposi's sarcoma-associated herpesvirus (KSHV) is linked to three different human cancers: Kaposi's sarcoma, primary effusion lymphoma, and multicentric Castleman's disease. The Kaposi's sarcoma lesion expresses high levels of angiogenic factors and is comprised of a mixed cell population, including endothelial cells that are infected with KSHV. We find that the KSHV K1 protein is expressed in ...

Amemiya, Morimasa, Kaoru Tabei, Eiji Kusano, Yasushi Asano, and Robert J. Alpern. Incubation of OKP cells in low-K1 media increases NHE3 activity after early decrease in intracellular pH. Am. J. Physiol. 276 (Cell Physiol. 45): C711–C716, 1999.—Chronic hypokalemia increases the activity of proximal tubule apical membrane Na1/H1 antiporter NHE3. The present study examined the effect of the incub...

Neonatal meningitis, caused by Escherichia coli K1, is a serious central nervous system disease. We have established that macrophages serve as permissive niches for E. coli K1 to multiply in the host and for attaining a threshold level of bacterial load, which is a prerequisite for the onset of the disease. Here, we demonstrate experimentally that three N-glycans in FcγRIa interact with OmpA of...

BACKGROUND Primary pyogenic liver abscess (PLA) caused by Klebsiella pneumoniae is an emerging infectious disease. Capsular serotype K1 and the magA gene have been reported to be associated with this disease. METHODS The prevalence of magA was determined by polymerase chain reaction (PCR). The sequences of the magA flanking region were completed by inverse PCR and direct sequencing. Serotypin...

We isolated PCR, RNA ligase-mediated rapid amplification of cDNA ends (RLM-RACE-PCR)-, and RT-PCR-generated clones from mouse kininogen family transcripts. DNA sequencing indicated that the clones were from two distinct genes. One set (K1) is from the previously reported mouse kininogen gene. The second set (K2) has an open reading frame, is 93% identical to K1 in the overlapping nucleotide seq...
