In our framework for molecular robot development, the system components of molecular robots and simple classifier rules were used to alleviate the computational burden. The design consists of a basic model that generates rule-based classifier gates in several binary tree and cancer classifications based on micro (mi)RNA expression. Simulation results showed that detection and classification were rapid using this system

The aim of this study was to determine the serologic features of anti-D in individuals expressing a weak D other than type 1 or type 2 and to assess whether the anti-D was an allo- or autoantibody. Serologic D typing and molecular analyses were performed on 748 individuals. Serologic characterization of anti-D

The molecular bases associated with these antigens have been determined, making it possible to distinguish HY and JO from wild-type DO. This provides a tool to predict the probable phenotype of patients and to screen for antigen-negative donors. PCR-RFLP assays and a microchip assay were used to determine the frequency of HY and JO

Various pairs of universal primers have been developed in the past to amplify short and long nematode sequences. However, certain nematode taxa were not readily amplified and/or sequenced with the existing primer tools. Frequently, the center region of a roughly 1,000 nucleotide segment would be lost.

Panels of monoclonal antibodies (MoAb) are being developed to identify D variants such as partial D and weak D when there are anomalous D typing results; however, molecular characterization offers a more specific classification of weak and partial D. The weak D and partial D phenotypes are caused by many different RHD alleles encoding aberrant D proteins, resulting in distinct serologic phenotypes

The taxonomy and the systematics of the genus Makatinus are discussed by means of the characterization of its morphological pattern and the first molecular (D2–D3 expansion segments of 28S rDNA) analysis of a representative of this taxon, Makatinus crassiformis from Costa Rica. The presence of two or more pairs of male ad-cloacal genital papillae is the most characteristic autapomorphy of the genus, but the status of its species on this concern differ among them.

Accurate blood group antigen typing of red blood cells with a positive direct antiglobulin test or from a recently transfused patient has been a long-standing problem. To overcome this problem, we evaluated the feasibility of using somatic cells as a source of DNA for molecular genotyping. Two sources of cells that could be obtained by noninvasive procedures were chosen for analysis: urine samples, which were already available in the clinical laboratory, and buccal epithelial cells collected

Molecular diagnostics is the fastest growing area of clinical laboratory medicine. The ability to rapidly amplify genes of bacterial, viral, or human origin, and the development of DNA array platforms, are driving a technology revolution in the clinical laboratory. A DNA-based testing approach is particularly applicable to blood bank and transfusion medicine for rapid, cost-effective antigen typing. Experience with DNA-based methods during the past decade has shown that these

) analysis (Powers et al., 2016). Mesocriconema nebraskense (Olson et al., 2017) was described as a monosexual, cryptic species sympatrically distributed with its cryptic counterpart, M. curvatum (Raski, 1952; Loof and De Grisse, 1989; Olson et al., 2017). In this paper, we describe the new species M. abolafiai n. sp., based on morphological and molecular characteristics.

., 2016). Thus, additional identification methods, particularly molecular-based identification, which requires a small amount of nucleic acid extracted from a single individual, will allow more accurate nematode identification, regardless of developmental stage (Handoo et al., 2016). The present study aimed to characterize R. similis using a combined morphological and morphometric approach and to confirm its identity using rDNA sequencing.

In the past, Meloidogyne species were identified using morphological and morphometric characterizations, and consequently, a large number of Meloidogyne spp. were described without molecular data (Karssen, 2002; Perry et al., 2009). Although molecular approach has facilitated the identification process

Allele B(A)02 with a 700C>G mutation,allele B(A)04 with a single 640A>G substitution, and allele B(A)05 with a 641T>C mutation were detected in multigenerational families and unrelated blood donors. Neither the B(A)01 nor B(A)03 alleles with 703A>G substitutions were observed in this study. In addition, a
