Confirmation that the JAHK antigen is associated with the rG haplotype

Anti-JAHK, an antibody directed toward a low-incidence antigen in the Rh system, was detected during routine antibody identification in a male donor who had no history of transfusion. Examples of anti-JAHK have been found in sera containing multiple antibodies to low-incidence antigens. The first report of anti-JAHK was in 1995 and described the association of the JAHK antigen with the rG haplotype. Our results confirm this association.

Mitochondrial Haplotype-based Identification of Root-knot Nematodes (Meloidogyne spp.) on Cut Foliage Crops in Florida

and (ii) evaluate the feasibility of using the mtDNA haplotype as a molecular diagnostic tool for rapid identification of large samples of RKN. A total of 200 Meloidogyne females were collected from cut foliage plant roots. Meloidogyne spp. were identified by PCR and RFLP of mitochondrial DNA. PCR and RFLP of mitochondrial DNA were effective in discriminating the Meloidogyne spp. present. Meloidogyne incognita is the most dominant RKN on cut foliage crops in Florida and must be a high target for

BDNF gene polymorphisms and haplotypes in relation to cognitive performance in Polish healthy subjects

Making Test (TMT), the Stroop Test which are to a large extent connected with prefrontal cortex activity. Our sample consisted of 460 healthy participants from Polish population. We detected possible association between five BDNF polymorphisms (rs11030101, rs10835210, rs2049046, rs2030324, rs2883187) and TMT_A. Additionally, one haplotype block made from eleven BDNF variants (rs2883187, rs1401635, rs2049046, rs2030324, rs11030101, rs10835210, rs1013402, rs1401635, rs1013402), as

Three of the 16 haplotypes were shared by populations from The Netherlands, Africa, and Asia. North America was represented by only one population of P. penetrans and it was the only member of one haplotype. The study by Janssen et al. (2017) also revealed cryptic biodiversity within P. penetrans, as morphologically indistinguishable populations from The Netherlands were assigned to different

High Mitochondrial Genome Diversity and Intricate Population Structure of Bursaphelenchus xylophilus in Kyushu, Japan

, clearly classified into two clades. Haplotype diversity was 0.83, evidencing a remarkable high diversity within Kyushu. The high genetic differentiation among the 12 populations (0.331) might be due to past invasion and expansion routes of PWN in northeastern and southeastern Kyushu. The distinct genetic composition of populations within the northwestern, central western, and southwestern Kyushu seems to be mostly related to the extinction of pine forests and long-range migration of PWN due to human

The substitution model (GTR + G + I) was used for maximum-likelihood analysis with 200 bootstrap replications using software MEGA 7 and for Bayesian inference analysis (BI) using the software MrBayes 3.1.2 (Huelsenbeck and Ronquist, 2001). The COI haplotype data set was reduced by removal of redundant sequences using software Jalview.2.10 (Waterhouse et al., 2009).

the model that had the closest substitution rate and pattern to HKY + G. A median joining haplotype network analysis was performed using PopArt to identify haplotypes and further show possible intraspecific patterns (Leigh and Bryant, 2015) across the area sampled. Results No significant pattern was seen between amplification of COI and correlation to purity ratio and/or concentration of template DNA. COI sequences were obtained from 39 samples of Skrjabingylus from 38 M. mephitis hosts and 1 S

No potential donors were identified among family members or within the American Rare Donor Program;therefore,a unit of the patient’s RBCs was collected one week before her planned caesarian section. To improve our ability to supply blood for this patient in the future,molecular testing was performed. The patient was found to be homozygous for an RH haplotype in which a variant RHD*DAR, is linked to a variant RHCE*ceAR. The DAR-ceAR haplotype has been described in Dutch-African

Incidence of Rodgers-negative individuals in systemic lupus erythematosus patients

Early reports of anti-Rodgers (anti-Rg) noted that there was an increased number of the HLA-B8 phenotype among this group. This HLA type has recently been linked to a C4A (Rg) gene deletion found with increased frequency among systemic lupus erythematosus (SLE) patients. Healthy controls (n= 176) and SLE patients (n=102) were studied for their HLA haplotype and C4 allotype as well as their Rg phenotype. Six of 53 white and 3 of 49 black SLE patients were C4A-null and Rodgers-negative, a

and Quebec in Canada. Available sequence data of Ditylenchus species retrieved from GenBank were used to phylogenetically position this species within the genus Ditylenchus. In all studied genes, several single-nucleotide polymorphisms between the Canadian D. weischeri and both Russian haplotype and individuals of D. weischeri from C. arvense from Russia were found. The sequences of ITS rDNA, LSU D2D3 28S rDNA, and Hsp90 were used to construct separate dendrograms. For each of the three genes
