Background. In lung adenocarcinoma, the frequency of KRAS mutations is ethnicity dependent with a higher proportion in African Americans and white Caucasians than in Asians. The prevalence of these mutations among North Africans patients is unknown. The objective of this study was to report the frequency and spectrum of KRAS mutations in a group of Moroccan lung adenocarcinoma patients. Methods...

Background. The LRRK2 G2019S mutation is the most common genetic determinant of Parkinson's disease (PD) identified to date. This mutation, reported in both familial and sporadic PD, occurs at elevated frequencies in Maghreb population. In the present study, we examined the prevalence of the G2019S mutation in the Moroccan population and we compared the motor and nonmotor phenotype of G2019S ca...

The aim of this study is to fill a gap in intelligence research by presenting data for the average IQ in Morocco and for a comparable sample in Spain. Adult samples were administered the Raven Standard Progressive Matrices (SPM) (Raven, Court, & Raven, 2001) and scored for the total test and for the three sub-factors of gestalt continuation, verbal-analytical reasoning and visuospatial ability ...

BACKGROUND Determining risky behaviours of adolescents provides valuable information for designing appropriate intervention programmes for advancing adolescent's health. However, these behaviours are not fully addressed by researchers in a comprehensive approach. We report the protocol of a mixed methods study designed to investigate the health risk behaviours of Moroccan adolescents with the g...

AIMS To identify lactic acid bacteria (LAB) present in Moroccan dairy products to establish and preserve their microbial species diversity. METHODS AND RESULTS Thirty-seven samples were collected from different farms. A total of 146 LAB were isolated and subjected to (GTG)(5)-PCR analysis. Comparison of the profiles with data available at the Moroccan Coordinated Collections of Micro-organism...

BACKGROUND Suicidal behavior is a major cause of injury and death worldwide, especially among adolescents and young adults. Few studies have tackled this issue in the Arab world. The present study investigated the prevalence and the risk factors of suicidal behaviors among Moroccan school students. METHODS From April 2012 to November 2013, a cross-sectional study was conducted in the North-Ce...

INTRODUCTION Verrucous carcinoma of the external genitalia and perianal region is a rare variant of well-differentiated squamous cell carcinoma. It has been reported to have limited metastatic potential. CASE PRESENTATION We report the case of a 54 year-old Moroccan man who presented with locally advanced giant condyloma acuminatum (Buschke-Löwenstein tumor) after prolonged intervals of negle...

This chapter focuses on comparing the forecasting ability of the backpropagation neural network (BPNN) and the nonlinear autoregressive moving average with exogenous inputs (NARX) network trained with different algorithms; namely the quasi-Newton (Broyden-Fletcher-Goldfarb-Shanno, BFGS), conjugate gradient (Fletcher-Reeves update, Polak-Ribiére update, Powell-Beale restart), and Levenberg-Marqu...

INTRODUCTION Myelolipomas are uncommon, benign tumors composed of mature adipose tissue and hematopoietic elements. They mostly occur in the adrenal glands, but extra-adrenal myelolipomas have also been reported in other locations such as the presacral region, retroperitoneum, pelvis and mediastinum. Here, we present a case of an extra-adrenal myelolipoma in a rare site: the renal parenchyma. T...

The apparel supply chain is a dynamic industry made distinctive by demand uncertainty and the handling of very many Stock Keeping Units (SKUs) during one season, which make it impossible to forecast demand accurately. Hence, apparel brands have to continuously maintain reactivity to the changing trends in consumer fashion tastes through quickly creating new designs that are suitable for all cus...
