Genetic characterization of the Berber-speaking population of Souss (Morocco) based on autosomal STRs.

Background: The Souss, located in southern Morocco, is one of the oldest areas of human settlement in North Africa. Despite this historical relevance, the Souss has not received sufficient attention in terms of population genetic studies.

Methods: In this study, we utilized the AmpFlSTR Identifiler PCR amplification system to establish the allelic frequencies and statistical parameters of 15 autosomal STRs (Short Tandem Repeats) in 150 healthy unrelated Berber-speaking individuals from the Souss.

Exploring the Western Mediterranean through X-chromosome.

In this study, we investigate the forensic and population genetics properties of 21 X-chromosome markers (9 X-Alu insertions and 12 X-STRs) in a dataset composed of 716 individuals from 11 Western Mediterranean populations. The high values of combined forensic parameters indicate that this 21 X-loci panel can complement autosomal or uniparental markers in kinship analysis and complex deficient paternity testing in the populations studied. Population analyses revealed a lower differentiation between Western Mediterranean human groups for X-STRs than for X-Alu insertion polymorphisms.

Potential of Aedes albopictus to cause the emergence of arboviruses in Morocco.

In 2015, the mosquito Aedes albopictus was detected in Rabat, Morocco. This invasive species can be involved in the transmission of more than 25 arboviruses. It is known that each combination of mosquito population and virus genotype leads to a specific interaction that can shape the outcome of infection.

Perceived risk, safety climate and safety behavior on Moroccan construction sites.

In Morocco, the construction sector is very dynamic economically, but suffers from weak safety performance. The few available statistics about the rates of occupational injuries and fatalities point to an alarming situation. However, root causes are yet to be identified.

The Suprachiasmatic Nucleus of the Dromedary Camel (): Cytoarchitecture and Neurochemical Anatomy.

In mammals, biological rhythms are driven by a master circadian clock located in the suprachiasmatic nucleus (SCN) of the hypothalamus. Recently, we have demonstrated that in the camel, the daily cycle of environmental temperature is able to entrain the master clock. This raises several questions about the structure and function of the SCN in this species.

The sense of hearing in the Pacific oyster, Magallana gigas.

There is an increasing concern that anthropogenic noise could have a significant impact on the marine environment, but there is still insufficient data for most invertebrates. What do they perceive? We investigated this question in oysters Magallana gigas (Crassostrea gigas) using pure tone exposures, accelerometer fixed on the oyster shell and hydrophone in the water column. Groups of 16 oysters were exposed to quantifiable waterborne sinusoidal sounds in the range of 10 Hz to 20 kHz at various acoustic energies.

Genetic portrait of Jewish populations based on three sets of X-chromosome markers: Indels, Alu insertions and STRs.

Population genetic data for 53 X-chromosome markers (32 X-indels, 9 X-Alu insertions and 12 X-STRs) are reported for five populations with Jewish ancestry (Sephardim, North African Jews, Middle Eastern Jews, Ashkenazim, and Chuetas) and Majorca, as the host population of Chuetas. Genetic distances between these populations demonstrated significant differences, except between Sephardic and North African Jews, with the Chuetas as the most differentiated group, in accordance with the particular demographic history of this population. X-chromosome analysis and a comparison with autosomal data suggest a generally sex-biased demographic history in Jewish populations.

INDUCTION OF CELL CYCLE ARREST AND APOPTOSIS BY ORMENIS ERIOLEPIS A MORROCAN ENDEMIC PLANT IN VARIOUS HUMAN CANCER CELL LINES.

Background: (Asteraceae) is an endemic Moroccan subspecies, traditionally named "Hellala" or "Fergoga". It's usually used for its hypoglycemic effect as well as for the treatment of stomacal pain. As far as we know, there is no scientific exploration of anti tumoral activity of extracts.

Cutaneous leishmaniasis in Ouazzane and Sidi Kacem provinces, Morocco (1997-2012).

Cutaneous leishmaniasis (CL) is a major public health problem in Morocco. Three distinct parasites are involved; Leishmania tropica, Leishmania major and Leishmania infantum. The objective of this study is to investigate the epidemiological and the clinical features of endemic foci of CL in Sidi Kacem and Ouazzane provinces in the north of Morocco including molecular identification of parasites.

PAH Metabolites in Bile of European Eel (Anguilla anguilla) from Morocco.

Environmental pollution of fish with organic contaminants is a topic of rising attention in Morocco. Polycyclic aromatic hydrocarbons (PAH) are prominent organic contaminants which are rapidly metabolized in fish. Their metabolites are accumulated in the bile fluid and can be used to assess PAH exposure.

Unsupervised approach data analysis based on fuzzy possibilistic clustering: application to medical image MRI.

The analysis and processing of large data are a challenge for researchers. Several approaches have been used to model these complex data, and they are based on some mathematical theories: fuzzy, probabilistic, possibilistic, and evidence theories. In this work, we propose a new unsupervised classification approach that combines the fuzzy and possibilistic theories; our purpose is to overcome the problems of uncertain data in complex systems.

In Vivo Potential Anti-Inflammatory Activity of Melissa officinalis L. Essential Oil.

Melissa officinalis L. (Lamiaceae) had been reported in traditional Moroccan medicine to exhibit calming, antispasmodic, and strengthening heart effects. Therefore, this study is aimed at determining the anti-inflammatory activities of M.

Comparative study of four advanced 3d-conformal radiation therapy treatment planning techniques for head and neck cancer.

For the head-and-neck cancer bilateral irradiation, intensity-modulated radiation therapy (IMRT) is the most reported technique as it enables both target dose coverage and organ-at-risk (OAR) sparing. However, during the last 20 years, three-dimensional conformal radiotherapy (3DCRT) techniques have been introduced, which are tailored to improve the classic shrinking field technique, as regards both planning target volume (PTV) dose conformality and sparing of OAR's, such as parotid glands and spinal cord. In this study, we tested experimentally in a sample of 13 patients, four of these advanced 3DCRT techniques, all using photon beams only and a unique isocentre, namely Bellinzona, Forward-Planned Multisegments (FPMS), ConPas, and field-in-field (FIF) techniques.

Mitochondrial DNA control region variation from samples of the Moroccan population.

In an effort to facilitate forensic mitochondrial DNA (mtDNA) testing in Morocco, high-quality control region sequences from 509 individuals were generated using a comprehensive processing and data review system. This large dataset of random samples from various Moroccan population groups (Arab speaking, Berber speaking, and Sahrawi speaking) exhibited a low random match probability (0.52 %) and a mean of pairwise comparisons of 13.

Malnutrition and brain development: an analysis of the effects of inadequate diet during different stages of life in rat.

Protein malnutrition or undernutrition can result in abnormal development of the brain. Depending on type, age at onset and duration, different structural and functional deficits can be observed. In the present review, we discuss the neuroanatomical, behavioral, neurochemical and oxidative status changes associated with protein malnutrition or undernutrition at different ages during prenatal and immediately postnatal periods as well as in adult rat.
