BACKGROUND/AIM It has been reported from in vivo exposed experimental animals that paternal lead exposure reduces birth rate; however, there is limited evidence to suggest a decrease in the proportion of male births. This study investigated the role of paternal exposure to lower lead acetate doses on early embryonic development (implantation) and the sex ratio of their offspring. MATERIALS AN...
Nanofluidic systems, with critical dimension of 10~100nm, are ideal model system for various types of nanoporous membranes. Artificially fabricated nanofluidic channels and nanopores have been successfully used for studying fundamental molecular / fluidic transport behaviors in nanoscale, yet there is much potential to take advantage of nanofluidic systems for real-world engineering application...
Evaluation of plant richness and diversity is important in rangeland ecosystems because biological control, conservation of genetic resources and the control of natural ecosystems are possible by identifying diversity. One of the factors affecting the richness and diversity is animals' utilization of the vegetation. Therefore, this research was done to study the plant richness and diversity res...
AIMS To compare the culture and PCR methods for detection of Brucella melitensis in blood and lymphoid tissue samples obtained from slaughtered sheep (n = 162) testing positive/negative in serological tests (Rose Bengal test and serum agglutination test). METHODS AND RESULTS Of 162 sheep examined, 45 were positive and 117 negative in serological tests. A PCR assay based on a pair of Br. melit...
Differentiation of the immune system poses the following novel problems in control of expression of genetic material. For all autosomal loci, expression of a locus in a given cell always means expression of both alleles at the locus; however, immunoglobulin loci although autosomal, do not conform to this rule (1). Mature plasma (antibodyproducing) cells produce immunoglobulins specified by only...
Recent studies have suggested that physiological and behavioral traits may be transgenerationally inherited through the paternal lineage, possibly via non-genomic signals derived from the sperm. To investigate how paternal stress might influence offspring behavioral phenotypes, a model of hypothalamic-pituitary-adrenal (HPA) axis dysregulation was used. Male breeders were administered water sup...
Restriction Landmark Genome Scanning (RLGS) is a method that uses end-labeled (32)P NotI sites that are mostly associated with coding genes to visualizes thousands of DNA fragments as spots in two-dimensional autoradiograms. This approach allows direct detection of autosomal deletions as spots with half normal intensity. The method was applied to mouse offspring derived from spermatogonia expos...
