Estimates on the initial coefficients are obtained for normalized analytic functions f in the open unit disk with f and its inverse g = f −1 satisfying the conditions that zf ′ (z)/f (z) and zg ′ (z)/g(z) are both subordinate to a starlike univalent function whose range is symmetric with respect to the real axis. Several related classes of functions are… (More)

Sharp bounds for ja pþ2 À la 2 pþ1 j and ja p+3 j are derived for certain p-valent analytic functions. These are applied to obtain Fekete-Szegö like inequalities for several classes of functions defined by convolution.

The estimates for the second Hankel determinant a 2 a 4 – a 2 3 of the analytic function f (z) = z + a 2 z 2 + a 3 z 3 + · · · , for which either zf (z)/f (z) or 1 + zf (z)/f (z) is subordinate to a certain analytic function, are investigated. The estimates for the Hankel determinant for two other classes are also obtained. In particular, the estimates for… (More)

BACKGROUND/PURPOSE
The purpose of this research was to develop an alternative adjuvant for hepatitis B vaccine (HBsAg) that elicits a long-lasting immune response after a single administration. In this study, the suitability of Poly (D, L)-lactide-co-glycolic acid (PLGA), Poly lactic acid (PLA) and Chitosan polymers as adjuvants for HBsAg were investigated.… (More)

The practice of traditional medicine for the control of fertility in Nilgris is based on the use of plant medicine for many years. The aim of the present study is to evaluate the effect of hydroalcoholic extract of stem bark of Ailanthus excelsa Roxb (Simaroubaceae) (HEA) has been studied in rats to explore its antifertility activity. A strong… (More)

The general classes of multivalent starlike, convex, close-to-convex and quasi-convex functions are introduced. These classes provide a unified treatment to various known subclasses. Inclusion and convolution properties are derived using the methods of convex hull and differential subordination.
