Introduction: Nowadays, there is special interest in finding a new contraceptive drug with high safety and fewer side effects. Investigations have shown that dill (Anethum graveolens L.) can be used either as a menstrual cycle regulator or contraceptive. Since cell surface terminal sugars have crucial roles in oocyte maturation, fertilization and implantation, in this study we investigated the ...

This study evaluated the thickness of Dentin Bonding Agent (DBA) used for "immediate dentin sealing" of onlay preparations prior to final impression making for indirect restorations. In addition, the amount of DBA that is removed when the adhesive surface is cleaned with polishing or air abrasion prior to final cementation was evaluated. For this purpose, a standardized onlay preparation was pr...

Occupational noise-induced hearing loss (ONIHL) is associated with various risk factors in South African mines. We investigated the association between standard threshold shifts (STSs) and exposure to noise platinum mine dust (PMD), using demographic data, five years of annual audiometry screening results, data. Miners' age, sex, percentage (PLH), data were gathered, a linear mixed effects regr...

Diamond-Blackfan anemia (DBA) is a rare, pure red-cell aplasia that presents during infancy. Approximately 40% of cases are associated with other congenital defects, particularly malformations of the upper limb or craniofacial region. Mutations in the gene coding for the ribosomal protein RPS19 have been identified in 25% of patients with DBA, with resulting impairment of 18S rRNA processing an...

Diamond Blackfan Anemia (DBA) is an inherited bone marrow failure syndrome with clinical features of red cell aplasia and variable developmental abnormalities. Most affected patients have heterozygous loss of function mutations in ribosomal protein genes but the pathogenic mechanism is still unknown. We generated induced pluripotent stem cells from DBA patients carrying RPS19 or RPL5 mutations....

background: in an effort to understand what limits the virulence of malaria para­sites in relation to the host genetic and immunogenic background, we investi­gated the possibility that the parasite and host genotype crossover interac­tions constrain virulence. methods: two groups of mice from different genotypes were used (c57bl/6 (b6) and dba/2 mice). the mice were infected with a virulent par...

The skin of Swiss albino mice was exposed once to 0.16 #g. of 9,10-dimethyl-l ,~benzanthracene (DMBA) or 1,2,5,6-dibenzanthracene (DBA), followed by continuous t rea tment with croton oil. Other mice were exposed to 0.0~ ug. of the same carcinogens. Control mice were t reated once with acetone followed by continuous t r ea tmen t with croton oil. A higher incidence of skin tumors was observed f...

From a methodological viewpoint, the use of genetic models permits either bottom up or top down analyses of brain and behaviour relationships. In the first case, the starting point is a gene manipulation (null mutation or gene modification) with subsequent identification of the consequences at the behavioural level. In the second case, the starting point is an observed behavioural difference be...
