The synthetic juvenile hormone analogue (S)-hydroprene can control populations of the oriental cockroach Blatta orientalis Linnaeus. Eradication of B. orientalis infestations, however, can take in excess of two years. In an attempt to reduce the time (S)-hydroprene takes to eliminate a population of oriental cockroaches, we explored the possibility of using the oothecal endoparasitoid Aprostoce...

Moisture content (MC) is one of the most important factors that can affect many physical and mechanical properties of wood and veneers. MC strongly affects the final strength and durability of joints, development of surface checks in the wood and dimensional stability of the bonded assembly. In this study, plywood panels made from Alnus glutinosa (Alder), Fagus orientalis (Beech) and Picea orie...

Health care is receiving much higher priority and more funds than ever before in the Russian Federation. Russian health economist Igor Sheiman talks to Fiona Fleck.

The genus Amaranthus contains 44 species and belongs to the family of Amaranthaceae classified within the order of Caryophyllales. Within this order a number of allergenic species including Amaranthus retroflexus (Redroot pigweed), Beta vulgaris (sugar beet), Chenopodium album (Lambsquaters), Kochia scoparia (Burning bush), and Salsola kali (Russian thistle) have been acknowledged by the WHO/IU...

Marketed plants are an important but a vulnerable group of plants whose investigations as well as conservation should be considered with priority. The chemistry, and in some cases biological activities of novel iso ̄avonoids, nor-lignans, anthracene and naphthalene derivatives and poly prenylated ̄avonoids isolated and characterized from Hagenia abyssinica, Salsola somalensis, Hypoxis spp., Tave...

A PCR-based survey of hemoprotozoa parasites detected Babesia bigemina, Theileria orientalis and Trypanosoma theileri among cattle and water buffalo in Vietnam, and a new Babesia sp. closely related to Babesia ovata was detected in cattle only. In addition, Theileria annulata and Trypanosoma evansi were not detected in both cattle and water buffalo. Phylogenetic analysis detected T. orientalis ...

BACKGROUND Trema orientalis (T. orientalis Linn) has been used in the management of malaria in the western part of Nigeria and despite its application in ethnomedicine, there is dearth of scientific evidence to justify the acclaimed prophylactic antimalarial usage of the plant. The aim of this study is to assess the in vitro antiplasmodial cell-free assay and chemopreventive efficacy of the met...

AIMS Platycladus orientalis (Cupressaceae) is an old-growth tree species which distributed in the imperial parks and ancient temples in Beijing, China. We aim to (1) examine the genetic diversity and reproductive traits of old-growth and young populations of P. orientalis to ascertain whether the older populations contain a higher genetic diversity, more private alleles and a higher reproductiv...
