Docosahexaenoic acid (DHA), a PUFA of the n-3 family, inhibited the growth of FM3A mouse mammary cancer cells by arresting their progression from the late-G(1) to the S phase of the cell cycle. DHA upregulated p27(Kip1) levels by inhibiting phosphorylation of mitogen-activated protein (MAP) kinases, i.e., ERK1/ERK2. Indeed, inhibition of ERK1/ERK2(More)
The mechanism of synthesis of ornithine decarboxylase (ODC) at the level of translation was studied using cell culture and cell-free systems. Synthesis of firefly luciferase (Fluc) from the second open reading frame (ORF) in a bicistronic construct transfected into FM3A and HeLa cells was enhanced by the presence of the 5'-untranslated region (5'-UTR) of(More)
Rhesus macaques (Macaca mulatta) are widely used in developing a strategy for vaccination against human immunodeficiency virus by using simian immunodeficiency virus infection as a model system. Because the genome diversity of major histocompatibility complex (MHC) is well known to control the immune responsiveness to foreign antigens, MHC loci in Indian-(More)
The role of polyamines at the G1/S boundary and in the G2/M phase of the cell cycle was studied using synchronized HeLa cells treated with thymidine or with thymidine and aphidicolin. Synchronized cells were cultured in the absence or presence of α-difluoromethylornithine (DFMO), an inhibitor of ornithine decarboxylase, plus ethylglyoxal(More)
PURPOSE Few reports have been made on the therapeutic effects as well as pathological features of an antithrombin preparation in patients diagnosed with septic disseminated intravascular coagulation (DIC) by the diagnostic criteria for acute DIC. MATERIALS AND METHODS A total of 88 sepsis patients who had received inpatient hospital care during the period(More)
We report a case of asymptomatic adrenal hematoma that enlarged during a 3-year follow-up. A 66-year-old woman exhibited a 4 cm right adrenal mass, incidentally discovered by computed tomography of abdomen, which progressively enlarged to 6 cm in diameter during the 3 years. The patient underwent right adrenalectomy with a diagnosis of a suspected(More)
The cholesteryl ester transfer protein modulator dalcetrapib is currently under development for the prevention of dyslipidemia and cardiovascular disease. Dalcetrapib, a thioester, is rapidly hydrolyzed in vivo to the corresponding thiophenol which in turn is further oxidized to the dimer and mixed disulfides (where the thiophenol binds to peptides,(More)
By using a new bioassay-guided method, 2-hydroxy-4-methoxybenzaldehyde isolated from the root bark of Periploca sepium, a traditional Chinese medicine, showed repellent activity against the olive weevil (Dyscerus perforatus) at 62.5, 125, 250 and 500 microg/disc, respectively. In addition, it also exhibited antinematodal activity against Bursaphelenchus(More)
INTRODUCTION The Utstein-style guidelines have been used in various countries around the world, because they are suitable for evaluating regional emergency medical systems (EMSs) for patients who have an out-of-hospital cardiac arrest (OHCA). This report examined the present status of treating OHCA in Saga Prefecture and examined policies that can(More)
