I. The sera of two species of Taterillus, T. gracilis and T. pygargus, were analysed by electrophoresis with different media: acetate, starch gel and acrylamide. 2. The two principal fractions, albumin and transferrin, appear to have different mobilities according to the species and consequently can be used to differentiate these two species which are indistinguishable by the usual tests. 3. Th...

Climatic stress such as warming would alter physiological pathways in plants leading to changes in tissue chemistry. Elevated CO2 could partly mitigate warming induced moisture stress, and the degree of this mitigation may vary with plant functional types. We studied the composition of structural and non-structural metabolites in senesced tissues of Bouteloua gracilis (C4) and Pascopyrum smithi...

Ultraviolet inactivation of chloroplast formation was studied in synchronously dividing cultures of Euglena gracilis. Sensitivity to sublethal doses given at intervals throughout the cell cycle was greater just before cell division than during division. There was approximately a twofold difference in the doseresponse relationships for the periods of high and low sensitivity.

Various facial reanimation procedures can be performed for treating patients with chronic facial nerve paralysis. The radiologic imaging features of static and dynamic techniques are reviewed in this article with clinical correlation, including brow lift, eyelid weights and springs, gracilis free flaps, fascia lata grafts, temporalis flaps, and Gore-Tex suspension slings. Although the anatomic ...

Global minimum temperatures (TMIN) are increasing faster than maximum temperatures, but the ecological consequences of this are largely unexplored. Long-term data sets from the shortgrass steppe were used to identify correlations between TMIN and several vegetation variables. This ecosystem is potentially sensitive to increases in TMIN. Most notably, increased spring TMIN was correlated with de...

Las Chlorophytas han sido utilizadas en estudios de contaminación metales pesados anteriormente. Estas algas tienen la capacidad acumularse grandes alfombras talos que flotan y se adhieren las rocas intermareales costeras. Los son sustancias pueden ser tóxicas bajas concentraciones. Existen métodos para detección estos como Espectroscopia Absorción Atómica (EAA). Esta metodología puede utilizar...

this study was conducted to evaluate the morphological responses of two different species including capoeta gracilis and alburnoides eichwaldii due to construction of the tarik dam in the sefidrud river using geometric morphometric technique. for this purpose, a total of 80 specimens of c. gracilis and 60 specimens of a. eichwaldii were collected from upstream and down-stream of dam. the left s...

The larvae, pupae and cases of Triplectides misionensis Holzenthal and T. gracilis (Burmeister) are described from specimens collected in protected areas from northeastern Argentina. The larvae are easily differentiated by the coloration of the cephalic capsule, shape of the ventral apotome and submentum, anterior border of the pronotum, and coloration of the legs, among other characters, while...
