Projecting Ancient Ancestry in Modern-Day Arabians and Iranians: A Key Role of ...

The Arabian Peninsula is strategic for investigations centered on the early structuring of modern humans in the wake of the out-of-Africa migration. Despite its poor climatic conditions for the recovery of ancient human DNA evidence, the availability of both genomic data from neighboring ancient specimens and informative statistical tools allow modeling the ancestry of local modern populations. We applied this ...

Gastric microbiome diversities in gastric cancer patients from europe and asia ...

The human gastrointestinal tract harbors approximately 100 trillion microorganisms with different microbial compositions across geographic locations. In this work, we used RNASeq data from stomach samples of non-disease (164 individuals from European ancestry) and gastric cancer patients (137 from Europe and Asia) from public databases. Although these data were intended to characterize the human expression prof...

Profiling of lung microbiota discloses differences in adenocarcinoma and squamo...

The lung is a complex ecosystem of host cells and microbes often disrupted in pathological conditions. Although bacteria have been hypothesized as agents of carcinogenesis, little is known about microbiota profile of the most prevalent cancer subtypes: adenocarcinoma (ADC) and squamous cell carcinoma (SCC). To characterize lung cancer (LC) microbiota a first a screening was performed through a pooled sequencing...

Association of leukotriene A4 hydrolase with tuberculosis susceptibility using ...

Leukotriene A4 hydrolase (LTA4H) is a key enzyme in the eicosanoid pathway. lta4h locus polymorphisms have previously been linked to tuberculosis (TB) susceptibility and disease outcome in a Vietnamese dataset, but further studies suggested that those results were poorly reproducible. We, therefore, compared the full set of variants (113 SNPs) within the gene in a Portuguese dataset of 112 TB patients and 120 c...

Anatomical and Physiological Basis of Continuous Spike-Wave of Sleep Syndrome a...

OBJECTIVE: Early neonatal thalamic lesions account for about 14% of continuous spike-wave of sleep (CSWS) syndrome, representing the most common etiology in this epileptic encephalopathy in children, and promise useful insights into the pathophysiology of the disease. METHODS: We describe nine patients with unilateral neonatal thalamic lesions which progressed to CSWS. Longitudinal whole-night and high-density ...

Origin of Frontal Lobe Spikes in the Early Onset Benign Occipital Lobe Epilepsy...

Objective: Early onset benign occipital lobe epilepsy (Panayiotopoulos syndrome [PS]) is a common and easily recognizable epilepsy. Interictal EEG spike activity is often multifocal but most frequently localized in the occipital lobes. The origin and clinical significance of the extra-occipital spikes remain poorly understood. Methods: Three patients with the PS and interictal EEG spikes with frontal lobe topog...

LAMA2 Gene Analysis in a Cohort of 26 Congenital Muscular Dystrophy Patients

Congenital muscular dystrophy type 1A (MDC1A) is caused by mutations in the LAMA2 gene encoding laminin-alpha2. We describe the molecular study of 26 patients with clinical presentation, magnetic resonance imaging and/or laminin-alpha2 expression in muscle, compatible with MDC1A. The combination of full genomic sequencing and complementary DNA analysis led to the particularly high mutation detection rate of 96%...
