the feeding habit and developmental stages of cunaxa setriostris (hermann) on most injurious mite, tetranychus ludeni zacher was investigated in varanasi region, uttar pradesh, india. the female of c. setirostris as a dominant species of cunaxid mite completed its life cycle on t. ludeni within 27.5 ± 13.55 days having one larval followed by three nymphal stages. whereas, the male sex of the sa...

background essential oils (eos) possess antibacterial properties and represent a natural source to treat infections and prevent food spoilage. their chemical composition might be affected by the environmental condition and the developmental growth stages of the plant. objectives the current study aimed to determine the variations in chemical compositions and antimicrobial activities of the eos ...

MOTIVATION Drosophila melanogaster is a major model organism for investigating the function and interconnection of animal genes in the earliest stages of embryogenesis. Today, images capturing Drosophila gene expression patterns are being produced at a higher throughput than ever before. The analysis of spatial patterns of gene expression is most biologically meaningful when images from a simil...

To elucidate whether the differentiation capacity of hematopoietic stem cells (HSCs) is influenced by specific microenvironments, adult mouse bone marrow-derived HSCs were injected into mouse blastocysts. Embryos developing from injected blastocysts contained donor-derived cells at various developmental stages, and progeny of the stem cells were detected in hematopoietic tissues. Thus, HSCs der...

Abstract Early-middle Ediacaran organic-walled microfossils from the Doushantuo Formation studied in several sections Yangtze Gorges area, South China, show ornamented cyst-like vesicles of very high diversity. These are diagenetically permineralized and observed petrographic thin-sections chert nodules. Exquisitely preserved specimens belonging to seven species Appendisphaera , Mengeosphaera T...

this study describes the influences of variations in life history traits and developmental patterns of pelophylax ridibunda. the causes of this variation were investigated by comparing observed patterns of interpopulational differences from geographic variables. the aim of the study was to investigate whether embryos and larvae from different populations of p. ridibunda show the same pattern of...

the present study was conducted to investigate the prevalence of developmental stages of fasciola gigantica infection in lymnaea snails and their populations in sylhet region of bangladesh. a total of 1865 lymnaea snails were collected and examined, of which 56 (3%) were found to having infected with developmental stages of fasciola gigantica. only 4.08% infected of 515 snails were collected fr...
