Chemical Composition and Synergistic Antimicrobial Effects of Essential Oils From Four Commonly Used Satureja Species in Combination With Two Conventional Antibiotics

open access: yesChemistry &Biodiversity, EarlyView.
The chemical composition and the in vitro synergistic antimicrobial effects of four Satureja essential oils were investigated. Essential oils from Satureja montana and S. hortensis displayed strong antimicrobial effects, whereas S. calamintha and S. alpina exhibited relatively weaker antimicrobial activity.

LC‐DAD‐MSn and HR‐LC‐QTOF analysis of Ziziphus budhensis leaves and evaluation of their in vitro and in vivo biological activities

open access: yesChemistry &Biodiversity, Accepted Article.
Ziziphus budhensis is a species described in 2015 in Nepal poorly studied for its phytochemical composition and possible bioactivities. In this study, six extracts were obtained from Z. budhensis leaves using ultrasound assisted extraction with solvents in increasing polarity.

Conditional Copula Models for Right-Censored Clustered Event Time Data [PDF]

open access: yesarXiv, 2016
This paper proposes a modelling strategy to infer the impact of a covariate on the dependence structure of right-censored clustered event time data. The joint survival function of the event times is modelled using a parametric conditional copula whose parameter depends on a cluster-level covariate in a functional way. We use a local likelihood approach

Charting the landscape of the environmental exposome

open access: yesiMeta, Volume 1, Issue 4, December 2022., 2022
We describe the biological and chemical components of the environmental exposomes in three major environmental matrices that are highly relevant to human and social‐economical health—air, soil, and water. We discuss how different exposome components can interact with each other. Finally, we propose a list of outstanding challenges to be tackled to push

A surveillance of nosocomial candida infections: epidemiology and influences on mortalty in intensive care units

open access: yesThe Pan African Medical Journal, 2014
BACKGROUND: it was aimed to investigate the frequency of Candida infections (CI) in the intensive care units (ICU), to determine typing of candida to evaluate risk factors associated with CI and mortality, and to evaluate influence of CI on mortality ...

Edge-magic labelings for constellations and armies of caterpillars [PDF]

open access: yesarXiv, 2017
Let $G=(V,E)$ be an $n$-vertex graph with $m$ edges. A function $f : V \cup E \rightarrow \{1, \ldots, n+m\}$ is an edge-magic labeling of $G$ if $f$ is bijective and, for some integer $k$, we have $f(u)+f(v)+f(uv) = k$ for every edge $uv \in E$. Furthermore, if $f(V) = \{1, \ldots, n\}$, then we say that $f$ is a super edge-magic labeling.
