Distinguishing malignant from benign pleural effusions using routine cytology is a common diagnostic problem. Recently, genetic alterations, including microsatellite instability (MSI) and loss of heterozygosity (LOH), have been described in malignant pleural effusions and proposed as methods improving diagnostics. The purpose of this study was to evaluate a panel of molecular markers for the de...

Recent developments in sequencing technologies and bioinformatics analyses provide an unprecedented opportunity for cost and time effective high quality microsatellite marker discovery in nonmodel organisms for which no genomic information is available. Here, we use shotgun pyrosequencing of a microsatellite-enriched library to develop, for the first time, microsatellite markers for Alnus gluti...

Early diagnosis of lung cancer based on conventional screening procedures has been unable thus far to decrease lung cancer mortality. We explored the possibility of using microsatellite instability in the detection and screening of early phases of lung carcinogenesis. We studied tumor, histopathologically normal bronchial mucosa, and cytological specimens of 51 lung cancer patients for the pres...

Microsatellites have proved to be very useful as genetic markers, as they seem to be ubiquitous and randomly distributed throughout most eukaryote genomes. However, our laboratories and others have determined that this paradigm does not necessarily apply to the yellow fever mosquito Aedes aegypti. We report the isolation and identification of microsatellite sequences from multiple genomic libra...

Gastric cancer is one of the most aggressive malignancies. Although there has been a slight increase in overall survival due to inclusion targeted medications standard chemotherapeutic treatment paradigm, prognosis remains poor. New evidence suggests that certain molecular and histopathologic tumor characteristics, as well staging, may also influence patients’ prognosis. Indeed, two detailed ge...

In this study, genetic diversity of two different populations of Hamra goat breed of Morocco was investigated in 60 different samples (including 30 from Beni Arouss and 30 from Rommani) using fifteen microsatellite markers. A total of 145 alleles were detected with average number per locus of 8.67 and 8.07 in Beni Arouss and Rommani goats, respectively. The Shannon’s information index ranged fr...

Ceratocystis fimbriata sensu lato represents a complex of cryptic and commonly plant pathogenic species that are morphologically similar. Species in this complex have been described using morphological characteristics, intersterility tests and phylogenetics. Microsatellite markers have been useful to study the population structure and origin of some species in the complex. In this study we sequ...

Obligate mating of females (queens) with multiple males has evolved only rarely in social Hymenoptera (ants, social bees, social wasps) and for reasons that are fundamentally different from those underlying multiple mating in other animals. The monophyletic tribe of ('attine') fungus-growing ants is known to include evolutionarily derived genera with obligate multiple mating (the Acromyrmex and...

The objectives of the present study were to monitor the effect of backcrossing through microsatellite markers and to compare different marker assisted selection strategies. Four populations were developed using donor parents resistant to the bean golden mosaic virus and, for all crosses, only individuals resistant to the bean golden mosaic virus were backcrossed. For crosses ARC100-4 x DOR303 a...

The most common chromosomal abnormalities associated with autism are 15q11-q13 duplications. Maternally derived or inherited duplications of 15q pose a substantial risk for an autism phenotype, while paternally derived duplications may be incompletely penetrant or result in other neurodevelopmental problems. Therefore, the determination of maternal versus paternal origin of this duplication is ...
