The aims of the present work were to quantify ability to induce lucigenin-dependent chemiluminescence (CL) from 6-9 day-old human monocyte-derived macrophages exposed to various mineral fibers, and to examine the relationship between ability to induce CL and fiber size. All fiber samples induced the CL response from the cells. The relationship between the number of fibers administered and the C...

Macrobrachium aemulum madhusoodani Pillai & Unnikrishnan (2013) was recently described based on material from the Neyyar River, Kerala, India as a new subspecies of M. aemulum (Nobili, 1906). As however, both species and subspecies names are considered part of the species-group for nomenclatorial purposes (ICZN, Art. 45.1), the name is a junior homonym of Macrobrachium madhusoodani Unnikrishnan...

The crab Rhithropanopeus harrisii (Gould) (Brachyura; Xanthidae) was infected in the laboratory with the parasitic barnacle Loxothylacus panopaei (Gissler) (Cirripedia; Rhizocephala). Crabs and barnacles were collected in the Rhode River in the Chesapeake Bay, MD. Forty-three out of 153 R. harrisii, including stages from megalopa «1 mm of carapace width) to crab 8 stage (:±:8 mm of carapace wid...

the jirds, meriones persicus and m. libycus are two widespread species in iran. meriones libycus can be found in low lands of deserts and semi desert areas, but meriones persicus in high rocky regions of khorasan. in this research 190 skulls belonging to meriones persicus and meriones libycus of northeast of iran were at first identified on the basis of morphologic characters, and then were div...

calomyscus mystax is endemic to great balkhan mountains in southwestern turkmenistan. however there have been some inaccurate reports of existing this species in koprtdagh mts. and northern iran, but these were considered as calomyscus elburzensis and calomyscus grandis. phylogenetic analyses on cytb gene clustered samples from kopetdagh mts. in northeastern iran with one specimen of c. mystax ...

Effects of salinity on fertilization, embryonic stage, and early larval development and growth performances of short-spined white sea urchin, Salmacis sphaeroides were conducted under a controlled laboratory condition. The experiment was carried out with seven salinity treatments (15, 20, 25, 30, 35, 40 and 45 PSU), each of which was triplicated. Significantly highest fertilization success was ...

Populations of oak cork (Quercus suber L.) originated from different areas in Tunisia were analysed based on morphological characters to assess the overall degree of phenotypic variability, to detect similarities between the genotypes and to evaluate significant forest features. One-way ANOVA analysis shows a significant difference between oak cork populations and demonstrates that parameters m...

inter- and intra-population variations of a recently described endemic cyprinid fish alburnoides qanati coad and bogutskaya, 2009 collected from three localities in the kor river basin, iran, were studied by applying morphometric and meristic characters using canonical discriminate function analysis (dfa), principal component analysis (pca) and cluster analysis (ca). in dfa, the overall random ...

A morphometric evaluation of second-stage juveniles (J2), males, females, cysts, and eggs of several isolates of the tobacco cyst nematode (TCN) complex, Globodera tabacum tabacum (GTT), G. t. virginiae (GTV), and G. t. solanacearum (GTS) is presented. Morphometrics of eggs, J2, and males are considerably less variable than of females and cysts. No measurements of eggs and J2 are useful for ide...
