Background/Aims Despite some evidence supporting its utility, the role of adjunctive dobutamine in the management of septic shock remains unclear. Methods The nationwide prospective sepsis cohort of the Korean Sepsis Alliance was analyzed. Adult patients with septic shock receiving norepinephrine were enrolled over a 29-month period. Patients given a dobutamine infusion within 3 days of intensive care unit (ICU) admission were compared with patients who received no infusion. To balance baseline characteristics, propensity score matching (PSM) was used. Results Of 11,981 patients with sepsis, 1

Previous studies indicated that the quality of tropical composts is poorer than that of composts produced in temperate regions. The aim of this study was to test the type of manure, the use of co-composting with green waste, and the stabilization method for their ability to improve compost quality in the tropics. We produced 68 composts and vermicomposts that were analysed for their C, lignin and NPK contents throughout the composting process. Bayesian networks were used to assess the mechanisms controlling compost quality. The concentration effect, for C and lignin, and the initial blend qual

The HIV-1 envelope glycoprotein (Env) is present on the surface of the virion at a very low density compared to most other enveloped viruses. Substitution of various parts of the stalk domain of Env (gp41) with the corresponding elements from other viral glycoproteins has been shown to increase Env spike density on the cell membrane and surface of virus-like particles (VLPs). In this study, chimeric Env antigens were generated by replacing the transmembrane and cytoplasmic domains of HIV-1 Env with the corresponding regions from the influenza H5 hemagglutinin (HA) (gp140HA 2 tr) and by replaci

Chickens’ performance in judgment bias tests (JBT) can be limited as they are tested individually, causing fear and anxiety. The objectives were to apply a social-pair JBT to assess the effect of environmental complexity on slow-growing broiler chickens` affective states, and assess the impact of fearfulness, anxiety, and chronic stress on JBT performance.

Background: Cholesterol is especially abundant in nervous system, where it plays important role in different aspects of cellular structure (e.g. fluidity of cell membranes) and function (e.g. membrane). Several studies showed that there may be a link between depression and low cholesterol because of altered central serotonergic functions. On the other hand, some studies also showed either no such association or yielded inconsistent results. However, many studies have related low cholesterol with different psychiatric disorders. Hence, we intend to see the possible link between the two. Aim: To

Therefore, we aimed to identify the predictors associated with diagnostic delay and to evaluate the impact of diagnostic delay on clinical course in a Korean CD patient cohort. We performed a multicenter retrospective analysis of 1,047 CD patients registered in the Crohn's Disease Clinical Network and Cohort study in Korea.

Abstract The corticofugal tracts (CFT) are key agents of upper limb motor function. Although the tracts form high-intensity regions relative to surrounding tissue in T2-weighted magnetic resonance images (T2WI), the precise relations of signal intensities of the left and right CFT regions to hand function are unknown. Here, we tested the hypothesis that the different signal intensities between the left and right CFT signify clinically important differences of hand motor function. Eleven right-handed and eleven left-handed healthy volunteers participated in the study. Based on horizontal T2WI e

In contrast to previous studies in the field, this paper focuses on the topological properties of the shock contagion network as measured by pairwise Granger causality between economic output of countries.
