Background: Treatment of hypercholesterolaemia in Asia is rarely evaluated on a large scale, and data on treatment outcome are scarce. The Pan-Asian CEPHEUS study aimed to assess low-density lipoprotein cholesterol (LDL-C) goal attainment among patients on lipid-lowering therapy.Methods: This survey was conducted in eight Asian countries. Hypercholesterolaemic patients aged ≥18 years who had been on lipid-lowering treatment for ≥3 months (stable medication for ≥6 weeks) were recruited, and lipid concentrations were measured. Demographic and other clinically relevant information were collected, and the cardiovascular risk of each patient was determined. Definitions and criteria set by the updated 2004 National Cholesterol Education Program guidelines were applied.Results: In this survey, 501 physicians enrolled 8064 patients, of whom 7281 were included in the final analysis. The mean age was 61.0 years, 44.4% were female, and 85.1% were on statin monotherapy. LDL-C goal attainment was reported in 49.1% of patients overall, including 51.2% of primary and 48.7% of secondary prevention patients, and 36.6% of patients with familial hypercholesterolaemia. The LDL-C goal was attained in 75.4% of moderate risk, 55.4% of high risk, and only 34.9% of very high-risk patients. Goal attainment was directly related to age and inversely related to cardiovascular risk and baseline LDL-C.Conclusion: A large proportion of Asian hypercholesterolaemic patients on lipid-lowering drugs are not at recommended LDL-C levels and remain at risk for cardiovascular disease. Given the proven efficacy of lipid-lowering drugs in the reduction of LDL-C, there is room for further optimization of treatments to maximize benefits and improve outcomes. © 2011 The European Society of Cardiology.

Peptides | Year: 2010

Six novel peptides from the piscivorous cone snail, Conus parius were purified by reverse-phase HPLC fractionation of crude venom. With the use of matrix-assisted laser desorption ionization mass spectrometry and standard Edman sequencing methods, the peptides were characterized. Two peptides were identified as members of the m-2 and m-4 branches of the M-superfamily and were designated as pr3a and pr3b, while four peptides were identified as members of the O-superfamily and were designated as pr6a, pr6b, pr6c and pr6d. Peptide pr3a differs from the majority of the M-superfamily peptides in the presence of two prolines, which are not modified to 4-trans-hydroxyproline. In peptide pr3b, five amino acids out of the 16 non-cysteine residues are identical with those of μ-GIIIA and μ-PIIIA, suggesting that pr3b may be a divergent μ-conotoxin. Peptide pr6a is notable because of its extreme hydrophobicity. Peptide pr6c has three prolines that are unhydroxylated. Peptides pr6b and pr6d differ from the previously characterized O-superfamily peptides in the presence of an extended N-terminus consisting of six amino acids. Peptides pr3a, pr3b, pr6a and pr6b were demonstrated to be biologically active when injected intraperitoneally in fish. The identification and characterization of these peptides in venom of a fish-hunting species establish the divergence of gene products and their patterns of post-translational modification within superfamilies in a single Conus species. © 2010 Elsevier Inc.

We consider a tri-Trophic community module called intraguild predation (IGP) that includes a prey and its predator which share a common basal resource for their sustenance. The growth of the basal resource in the absence of predation follows the Hutchinson's equation where the delay parameter arises, while functional responses in our model are of Lotka-Volterra type. Moreover, the basal resource is harvested for its economic value with a constant harvesting rate. This work generalizes the previous works on the same model with no harvesting and no time delay. We show that the harvesting rate has to be small enough in order for the equilibria to exist. Moreover, we show that by increasing the delay parameter the stability of the equilibrium solutions may change, and periodic solutions may emerge through Hopf bifurcations. In the case of the positive equilibrium solution, multiple stability switches are obtained, and numerical continuation shows that a stable branch of periodic solutions emerges once the positive equilibrium loses its stability at the first Hopf bifurcation point. This result is important because it gives an alternative for the coexistence of all three species, avoiding extinction of one or more species when the positive equilibrium becomes unstable. © 2016 AIP Publishing LLC.

Let (ωn)n∈ℕ be the sequence of k-Fibonacci numbers recursively defined by ω1 = 1, ω2 = 1, ωn+2 = kωn+1 + ωn, ∀n ∈ℕ, and m be a fixed positive integer. In this work we prove that, for almost every x ∈ (0, 1), the pattern k, k, ⋯ k (comprising of m-digits) appears in the continued fraction expansion x = [0, a1, a2; ⋯] with frequency f(k,m) := (-1)m k/log 2 log {φm+1 -1φm -1}, where φm = ωm+1/ωm, i.e., limn→∞ 1/n #{j ∈ Ωn : aj+i = k for all i ∈ Ωm-1 ∪{0}} = f(k,m), where Ωn := {1, 2; ⋯, n}.

A coupled system of partial differential equations modeling the interaction of a fluid and a structure with delay in the feedback is studied. The model describes the dynamics of an elastic body immersed in a fluid that is contained in a vessel, whose boundary is made of a solid wall. The fluid component is modeled by the linearized Navier-Stokes equation, while the solid component is given by the wave equation neglecting transverse elastic force. Spectral properties and exponential or strong stability of the interaction model under appropriate conditions on the damping factor, delay factor and the delay parameter are established using a generalized Lax-Milgram method. © 2016, Springer International Publishing.

Zinc oxide (ZnO) films were synthesized using spray pyrolysis using glass as substrate at substrate temperature of 400°C. The precursor used is an aqueous solution of ZnCl2. The deposition was done in ambient conditions. It was observed that the zinc oxide films are textured. The films yielded 0.3 transmittance in the visible light spectrum as shown by the UV-vis spectrophotometry data. The FT-IR data implied that the films are of high purity. The ZnO films were subjected to bacteria Escherichia coli and Staphyllococcus aureus in agar diffusion assays, and the antibacterial activity was quantified by measuring the zone of inhibition created by the films. The ZnO films exhibited low antibacterial activity to E. coli and S. aureus. © 2013 The Authors. Published by Elsevier.

"Locating ourselves in the center of en masse urbanization⋯." Matnog, Sorsogon, Philippines, primarily a coastal area is not exempted from this socio-cultural shift. And in these changes, people, specifically that of the eight Girls, ages 14 to 18 years old living in the periphery of the coast, begin to question this condition of urbanization that has only created varied and severe strands of poverty in their area. "I look at their photographs and listen to their narrative⋯." Using Alice McIntyre's photovoice, the Girls took photographs of spaces that represent the concepts of poverty and development. I let them speak of these spaces and they begin to talk about "development" and "poverty," focusing on the existence of the Pier, the Coast and that of their lives. "Spatiality of the Pier⋯." Taking the postmodern lens, guided by Edward Soja's notions on spatiality is an attempt to view the unfolding of tensions emanating from urban spaces and their representations. The Pier and that of other spaces become the discursive arena that conjugate non-recognition of positions and conditions between the concepts of "poverty" and "development." With the Pier as the most imposing space emerges ambiguity and blurry vision affect how the Girls perceive, conceive and live in and along these spaces. Development as assumed to be an existing and workable paradigm through urbanization promise alteration of their condition does not exist for them. What happens is that "poverty" becomes the constant wherein time and space are in crisis; and, the spatiality of the Girls becomes fragmented and pulverized. "IT": For urbanization as a development agenda does not fulfill its promise to the Girls of Matnog, Sorsogon and to us. This knowledge as conceptualized for them place them in a position and state where they no longer recognize what development is. In this discourse, development, urbanization and spaces that represent them all becomes (in)visible that have become (un)recognizable and (un)familiar for the Girls and for us. This (non)recognition place all these concepts and spaces as an IT. Copyright © 2014, IGI Global.

This paper studies the local-in-time existence of classical solutions to a hyperbolic system with differential boundary conditions modelling a flow in an elastic tube. The well-known Lax transformations used for obtaining a priori estimates for conservation laws are difficult to apply here because of the inhomogeneity of the partial differential equations (PDE). Rather, our method relies on a suitable splitting of the original system into the PDE part and the ODE part, the characteristics for the PDE part, appropriate modulus of continuity estimates and a compactness argument. © 2016 John Wiley & Sons, Ltd.

Tinoc, Ifugao is located within the Cordillera Central Range, Northern Luzon, Philippines. It is inhabited by the Kalanguya, one of the indigenous societies in the Cordillera, who have a long tradition of using medicinal plants. The paper describes ethnomedicinal importance of 125 plant species, and healthcare practices as cited by 150 informers ranging between 16-90 yrs. Various ailments that are treated by the identified medicinal plants vary from common diseases such as headache, stomachache, toothache, cough and colds, and skin diseases to more serious ailments which includes urinary tract infection, dysentery, and chicken pox. There are different modes of preparation of these medicinal plants. For instance, immediate treatment for cuts was demonstrated by using crushed leaves of Eupatorium adenophorum L. An increased efficacy was noted by creating mixtures from combining certain plants. The medicinal plants are summarized by giving their scientific name, family, vernacular name and utilization.
