In vitro antimicrobial activity of a gel containing antimicrobial peptide AMP2041, chlorhexidine digluconate and Tris‐EDTA on clinical isolates of Pseudomonas aeruginosa from canine otitis

Veterinary Dermatology, Volume 27, Issue 5, Page 391-e98, October 2016., 2016
Background– Pseudomonas aeruginosa (PA) may cause suppurative otitis externa with severe inflammation and ulceration in dogs. Multidrug resistance is commonly reported for this organism, creating a difficult therapeutic challenge. Objective– The aim of this study was to evaluate the in vitro antimicrobial activity of a gel containing 0.5 µg/mL of ...

On the links between limit characteristic zeros and stability properties of linear time‐invariant systems with point delays and their delay‐free counterparts

Journal of Applied Mathematics, Volume 2004, Issue 4, Page 339-357, 2004., 2004
We investigate the relationships between the infinitely many characteristic zeros (or modes) of linear systems subject to point delays and their delay‐free counterparts based on algebraic results and theory of analytic functions. The cases when the delay tends to zero or to infinity are emphasized in the study.

Some inequalities for rational function with prescribed poles and restricted zeros

Demonstratio Mathematica
In this article, we first prove some auxiliary results in the form of lemmas using an improved Schwarz lemma at the boundary recently proved by Mercer. Furthermore, we establish some new inequalities for rational functions on the unit disk in the complex

A Novel Topical Emollient Plus for Canine Atopic Dermatitis: A Clinical Trial Assessing Efficacy and User Acceptance

Veterinary Dermatology, Volume 37, Issue 2, Page 293-305, April 2026.
Background: Canine atopic dermatitis (cAD) is a common, chronic skin condition characterised by epidermal barrier dysfunction, immune dysregulation and cutaneous dysbiosis. While “emollient plus” formulations are widely used in human atopic dermatitis, their role in cAD remains underexplored. Hypothesis/Objectives: To evaluate the clinical efficacy and

A new inequality for a polynomial

International Journal of Mathematics and Mathematical Sciences, Volume 28, Issue 11, Page 679-684, 2001., 2001
Let p(z)=a0+∑j=tnajzj be a polynomial of degree n, having no zeros in |z| < k, k ≥ 1 then it has been shown that for R > 1 and |z| = 1, |p(Rz) − p(z)| ≤ (Rn − 1)(1 + AtBtKt+1)/(1 + kt+1 + AtBt(kt+1 + k2t))max|z|=1|p(z)|−{1 − (1 + AtBtkt+1)/(1 + kt+1 + AtBt(kt+1 + k2t))}((Rn − 1)m/kn), where m = min|z|=k|p(z)|, 1 ≤ t < n, At = (Rt − 1)/(Rn − 1), and Bt =

Sharper upper bounds on maximum modulus for rational functions

Demonstratio Mathematica
We study upper bounds for rational functions r(z)=p(z)w(z) $r\left(z\right)=\frac{p\left(z\right)}{w\left(z\right)}$ , where w(z)=∏j=1n(z−λj),|λj|>1, $w\left(z\right)={\prod }_{j=1}^{n}\left(z-{\lambda }_{j}\right), \vert {\lambda }_{j}\vert { >}1,$ and

Some Inequalities on Polynomials in the Complex Plane Concerning a Linear Differential Operator

Journal of Mathematics, Volume 2026, Issue 1, 2026.
In this paper, we consider new extremal problems in the uniform norm between a univariate complex polynomial and its associated reciprocal polynomial involving a generalized B‐operator. Our first result deals with inequality for the upper bound of a polynomial having s‐fold zero at the origin governed by generalized B‐operator, and as applications of ...

Integral mean estimates for polynomials whose zeros are within a circle

International Journal of Mathematics and Mathematical Sciences, Volume 28, Issue 4, Page 231-235, 2001., 2001
Let p(z) be a polynomial of degree n having all its zeros in |z| ≤ k; k ≤ 1, then for each r > 0, p > 1, q > 1 with p−1 + q−1 = 1, Aziz and Ahemad (1996) recently proved that n{∫02π|p(eiθ)|rdθ} 1/r≤{∫02π|1+keiθ|prdθ} 1/pr{∫02π|p′(eiθ)|qrdθ} 1/qr. In this paper, we extend the above inequality to the class of polynomials p(z)=anzn+∑v=μnan−vzn−v;1≤μ≤n ...

Evaluation of filaggrin 2 expression in dogs with atopic dermatitis before and after oclacitinib maleate administration

Veterinary Dermatology, Volume 36, Issue 4, Page 453-461, August 2025.
Background – Canine atopic dermatitis (cAD) is a chronic, inflammatory, multifactorial and pruritic disease. The presence of skin barrier impairment (e.g. filaggrin alterations), along with abnormal immune responses, can negatively impact cutaneous barrier function.

Some inequalities for maximum modules of polynomials

International Journal of Mathematics and Mathematical Sciences, Volume 14, Issue 2, Page 233-238, 1991., 1990
A well‐known result of Ankeney and Rivlin states that if p(z) is a polynomial of degree n, such that p(z) ≠ 0 in |z| < 1, then max|z|=R≥1|p(z)|≤(Rn+12)max|z|=1|p(z)|. In this paper we prove some generalizations and refinements of this result.
