Genome size and chromosome number of five Cimicidae species were compared with the similar data recently received from Cimex lectularius parasitizing human. The average nuclear DNA content (males) was 2C = 1.47 pg in C. hemipterus, 2C = 1.61 pg in C. hirundinis, 2C = 1.80 pg in C. lectularius from bats, 2C = 1.68 pg in C. pipistrelli, and 2C = 1.22 pg in Paracimex cf. chaeturus. In the genomes of all cimicid species analyzed, the average GC content ranged from 32.74% in C. pipistrelli to 35.87% in P. cf. chaeturus. Chromosome variability with two male cytotypes, 2n = 28 + X X Y and 28 + X X X Y, was confirmed in C. pipistrelli. In addition, intraspecific variability in chromosome number was revealed in C. lectularius from bats with 2n = 26 + X X Y and 26 + X X X Y. We suggest that the origin of intraspecific variability in chromosome number of C. lectularius from bats and C. pipistrelli is not only the result of simple fragmentation, but additive rearrangements like duplications are probably also involved. © 2019 International Society for Advancement of Cytometry.

An analysis of transcriptomes from the antennae of the three South American stink bugs (Euschistus heros, Chinavia ubica, and Dichelops melacanthus) revealed the presence of picorna-like virus genome-...
Most crucifer species (Brassicaceae) have small nuclear genomes (mean 1C-value 617 Mb). The species with the largest genomes occur within the monophyletic Hesperis clade (Mandáková et al., Plant Phy...
Recent advances in DNA synthesis technology have made it possible to rewrite the entire genome of an organism. The major hurdles in this process are efficiently identifying and fixing the defect-induc...
The parasite manipulation hypothesis states that the parasite modifies host's behavior thereby increasing the probability that the parasite will pass from an intermediate host to its final host. We us...
The reduviid subfamily Triatominae, also called kissing bugs, are vectors of Chagas disease, which is one of the most seriously neglected tropical parasitic diseases. Only three complete mitochondrial...
In the nutrition guideline (A.S.P.E.N guideline), there was no recommendation about the feeding type in enteral feeding of critically ill patients. Continuous feeding is the most popular f...
During the last years, the investigators were the witness to the increase of a old emerging pest due to bed bugs (Cimex lectularius) in the world. Insecticides resistances apparitions and ...
The purpose of this study is to determine if naso-jejunal feeding (feeding beyond the stomach) improves the efficacy of enteral feeding (feeding into the gut) in critically ill patients. ...
In this study, we want to see how feeding affects breathing in small premature babies. Using a special feeding tube in the stomach, we can measure how the diaphragm (a large breathing musc...
The purpose of this study is to gain a better understanding of the satiation measures that influence human eating behavior in regard to intake of large portion sizes at a meal. The investi...
The amount of DNA (or RNA) in one copy of a genome.
A coordinated effort of researchers to map (CHROMOSOME MAPPING) and sequence (SEQUENCE ANALYSIS, DNA) the human GENOME.
Nutritional support given via the alimentary canal or any route connected to the gastrointestinal system (i.e., the enteral route). This includes oral feeding, sip feeding, and tube feeding using nasogastric, gastrostomy, and jejunostomy tubes.
Clinical conditions caused by an abnormal sex chromosome constitution (SEX CHROMOSOME ABERRATIONS) in which there is extra or missing sex chromosome material (either a whole chromosome or a chromosome segment).
Specific regions that are mapped within a GENOME. Genetic loci are usually identified with a shorthand notation that indicates the chromosome number and the position of a specific band along the P or Q arm of the chromosome where they are found. For example the locus 6p21 is found within band 21 of the P-arm of CHROMOSOME 6. Many well known genetic loci are also known by common names that are associated with a genetic function or HEREDITARY DISEASE.
Bioinformatics is the application of computer software and hardware to the management of biological data to create useful information. Computers are used to gather, store, analyze and integrate biological and genetic information which can then be applied...
