OBJECTIVES The high values of thermal resistance (Rct) and/or vapor resistance (Ret) of chemical protective clothing (CPC) induce a considerable thermal stress. The present study compared the physiological strain induced by CPCs and evaluates the relative importance of the fabrics' Rct, Ret, and air permeability in determining heat strain. METHODS Twelve young (20-30 years) healthy, heat-accl...

We recently reported (Clewell et al., 1972) on an inhibitory effect of rifampicin on Co1 E 1 plasmid replication. The present study represents a further characterization of this phenomenon as well as a study of the effects of two other known inhibitors of RNA synthesis, streptolydigin and actinomycin D. During treatment of cells with chloramphenicol the colicinogenic factor El (Co1 El) continue...

background: the heartworm disease is an infectious disease of dogs with dirofilaria immitis combined with cardiovascular and circulatory abnormalities. the heartworm disease can become a serious health risk when associated with a severe infection. in this study, a male, 8 year-old dog that died suddenly was necropsied and all tissues were examined grossly. methods: major organs including heart,...

Chthamalus anisopoma is a rock-inhabiting barnacle which appears in two radically different morphs: the shell may be either conical or bent at a right angle. Based on field experiments, it was previously concluded that the two morphs are phenotypic variants, with the bent morph being induced by the presence of a predator gastropod. In the present study we used molecular data in order to examine...

Received 16 May 2016 Accepted 19 Oct 2016 Abstract Background: One of the most important zoonotic helminths in the world is known as Echinococcus granulosus. Different strains of the E. granulosus have been described based on morphological and molecular characterizations, however, there is limited information regarding the characteristics of the phenotypes and genotypes of E. granulosus in Iran...

Odonate larvae are commonly considered opportunistic general predators in freshwater ecosystems. However, the dietary breadth of most odonate larvae in forest streams is still poorly documented. We characterized the prey species and estimated the level of dietary niche overlap of two damselflies, Euphaea formosa Hagen 1869 and Matrona cyanoptera Hämäläinen and Yeh, 2000 in a forest stream of ce...

Chemical and structural heterogeneity and the resulting interaction of coexisting phases can lead to extraordinary behaviours in oxides, as observed in piezoelectric materials at morphotropic phase boundaries and relaxor ferroelectrics. However, such phenomena are rare in metallic alloys. Here we show that, by tuning the presence of structural heterogeneity in textured Co1?xFex thin films, effe...

Different strains of the E. granulosus have been described based on morphological and molecular characterizations, however, there is limited information regarding the characteristics of the phenotypes and genotypes of E. granulosus in Iran. METHODS The present study was prepared to evalua...

Hypoderma spp. larvae cause subcutaneous myiasis in several animal species. The objective of the present investigation was to identify and characterize morphologically and molecularly the larvae of Hypoderma spp. collected from cattle (Bos taurus taurus) and red deer (Cervus elaphus) in the district of Castelo Branco, Portugal. For this purpose, a total of 8 larvae were collected from cattle (n...
