Increasing evidence from epidemiological, clinical, and basic mechanistic studies supports the importance of HDL in preventing or even reversing atherosclerosis. The well-known structural and compositional diversity of HDL subfractions seems to be an important, if still somewhat unclear, factor in the atheroprotective potential of a given HDL particle. Perhaps as important as the parameter of p...

Lipoprotein little a (small case a as opposed to a capital A) has been confusing lipidologists for a long, long time since it was first discovered in 1963. It seems to be a risk factor in some people and not in others and race is involved. Over time the data associating Lp(a) with CV risk has gotten stronger and stronger and current opinion is until proven otherwise that Lp(a) is an independent...

Some results on the properties of T -flat, quasiT -flat,  T -flat,  T -flat, T -semi-symmetric,  T Ricci recurrent and T - -recurrent LP-Sasakian manifolds are obtained. It is also proved that an LP-Sasakian manifold satisfying the condition T . 0 S  is an  -Einstein manifold. MSC 2000. 53C15, 53C25, 53C50, 53D15.

For p ∈ R, the generalized logarithmic mean Lp a, b , arithmetic mean A a, b and geometric mean G a, b of two positive numbers a and b are defined by Lp a, b a, a b; Lp a, b a 1 − b 1 / p 1 a − b , p / 0, p / − 1, a/ b; Lp a, b 1/e b/a 1/ b−a , p 0, a/ b; Lp a, b b − a / ln b − lna , p −1, a/ b; A a, b a b /2 and G a, b √ ab, respectively. In this paper, we give an answer to the open problem: f...

We consider the problem of estimation of regression coefficients under general classes of error densities without assuming classical regularity conditions. Optimal orders of convergence rates of regression-equivariant estimators are established and shown to be attained in general by Lp estimators based on judicious choices of p. We develop a procedure for choosing p adaptively to yield Lp estim...

Natural resistance of humans to the cattle pathogen Trypanosoma brucei brucei has been attributed to the presence in human serum of nonimmune factors that lyse the parasite. Normal human serum contains two trypanosome lytic factors (TLFs). TLF1 is a 500-kDa lipoprotein, which is reported to contain apolipoprotein A-I (apoA-I), haptoglobin-related protein (Hpr), hemoglobin, paraoxonase, and apoA...

Immunochemical studies of the major density classes established clearly the antigenic heterogeneity of the human plasma lipoprotein system [ 1 -3 ] . Recent chemical investigations have confirmed these earlier findings and demonstrated the presence of six antigenicalty distinct polypeptides designated as A-I,. A-II, C-I, C-II, C-Ill and LP-B* [4 -6 ] . An additional antigenic component detected...

Background and Objectives: Lipoprotein-a potentially represents a useful tool for risk stratification in cardiovascular accidents.  The aim of this study was to evaluate the atorvastatin effect on serum lipid profile & lipoprotein A. Material & Methods: In 2009, 405 patients with acute coronary syndrome randomly were divided into 2 groups, taking 20 & 40 mg atorvastatin daily for 3 months. Lip...

background: some coincidental disorders with migraine have been introduced that may have role in its pathogenesis or aggravation. in this study we determined the relative frequency of hyperlipidemia as a coincidental disorder in patients affected by migraine. methods: a total of 102 migraine-affected patients according to international headache society (his) criteria and 103 control subjects ad...
