Purpose: The aim of the study is to compare the perceived benefits of public libraries between five culturally different countries: Finland, Norway, the Netherlands, South Korea and the U.S. Design/methodology/approach: The data was based on representative samples of Finnish, Norwegian, Dutch, Korean and American adult library users. In Finland a mail survey was used and in other countries web ...
effects of inbreeding coefficient on estimates of genetic parameters, breeding values and genetic trends for production traits (milk, fat and protein yields), reproduction traits (age at the first calving, interval between first insemination to conception, calving interval, interval between calving to first insemination, and calving ease) as well as longevity of holstein cattle in iran were stu...
The performance of pigs is influenced by genetic and environmental factors. Both the genetic merit of the pigs and the environment they are raised in have to be improved continuously to optimise progress in performance. In addition, the requirements of genotypes available today may have changed due to selection and the management of pigs has to be adopted accordingly to maximise phenotypic perf...
Background : Mustard gas may cause acute (early) and chronic (late) lesions. Acute lesions include disseminated bullous lesions on skin, respiratory, and GI disorders chronic complications are chronic bronchitis, severe asthma, and malignancies. B cells are active part of humoral immunity that secrete antibodies to defend our body. Materials and methods : We have evaluated 3 groups of patients,...
Children with autism spectrum disorders (ASD) have unique developmental and behavioral phenotypes, and they have specific challenges with communication, social skills, and repetitive behaviors. At this time, no single etiology for ASD has been identified. However, evidence from family studies and linkage analyses suggests that genetic factors play a pivotal role in the etiology of ASD. However,...
Epigenetic alterations have been related to many biological processes and disease; however, the global epigenetic status of most cell types has not been investigated yet in detail. The ability of environmental factors to promote a phenotype or disease state not only in the individual exposed but also in subsequent progeny for successive generations is termed transgenerational inheritance. The m...
mental retardation (mr) is one of the most frequently found major genetic disorders around the world, affecting 1-3% of the people in the general population. the recent advancement in molecular biology and cytogenetic study has made possible the identification of new genes for a variety of genetic disorders including autosomal recessive mr. recessive genetic disorders are common in pakistan due...
Background: IFN-g is one of the most essential and fundamental player in initiation and development of T1DM. This mediator belongs to T Helper-1(Th1) class of cytokines and exerts stimulation and differentiation of naïve T cells towards Th1 cells and meanwhile inhibits differentiation and proliferation of Th2 cells. These effects are highly important in induction and progression of cell-mediate...
Forward genetics is the identification and characterization of gene that responsible for mutant phenotype. It starts with measurement or observation a phenotype followed by mapping causative loci genes. In addition, forward genetic approaches are, unbiased in terms since primary level measurement. Reverse genetics, on other hand, analyzes an organism following disruption known gene. To generate...
