Tis is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. In Morocco, Leishmania infantum species is the main causative agents of visceral leishmaniasis (VL). However, cutaneous leishmaniasis (CL) due to L. infantum has been reported sporadically. Moreover, the recent geographical expansion of L. infantum in the Mediterranean subregion leads us to suggest whether the nonsporadic cases of CL due to this species are present. In this context, this review is written to establish a retrospective study of cutaneous and visceral leishmaniasis in northern Morocco between 1997 and 2018 and also to conduct a molecular study to identify the circulating species responsible for the recent cases of leishmaniases in this region.

Therefore, this essay proposes to use Leaf Area Index (LAI) to assess the consequences of the oases long-term biodegradation. The index was used as a widely-applied parameter of vegetation structure and an important indicator of plant growth and health. Therefore, a new optical multispectral Sentinel-2 data were used to build a long term LAI time series for the area of the Erfoud and Rissani oases, Errachidia province in Drâa-Tafilalet region in Morocco.

Parasites & Vectors (2017) 10:100 DOI 10.1186/s13071-017-2032-9 RESEARCH Open Access Circulating species of Leishmania at microclimate area of Boulemane Province, Morocco: impact of environmental and human factors Asmae Hmamouch1,2*, Mahmoud Mohamed El Alem1,3, Maryam Hakkour1,3, Fatima Amarir4, Hassan Daghbach5, Khalid Habbari6, Hajiba Fellah1,3, Khadija Bekhti2 and Faiza Sebti1,6 Abstract Background: Cutaneous leishmaniasis (CL) is widely distributed in Morocco where its geographical range and incidence are related to environmental factors. This study aimed to examine the impact of several factors on the distribution of CL in Boulemane Province, which is characterized by several microclimates, and to identify the Leishmania species circulating in these areas. Methods: Ordinary least squares regression (OLSR) analysis was performed to study the impact of poverty, vulnerability, population density, urbanization and bioclimatic factors on the distribution of CL in this province. Molecular characterization of parasites was performed using a previously described PCR-RFLP method targeting the ITS1 of ribosomal DNA of Leishmania. Results: A total of 1009 cases were declared in Boulemane Province between the years 2000 and 2015 with incidences fluctuating over the years (P = 0.007). Analyzing geographical maps of the study region identified four unique microclimate areas; sub-humid, semi-arid, arid and Saharan. The geographical distribution and molecular identification of species shows that the Saharan microclimate, characterized by the presence of Leishmania major was the most affected (47.78%) followed by semi-arid area where Leishmania tropica was identified in three districts.

The conclusions and viewpoints presented in the report are those of the author and do not necessarily coincide with those of the client. A pdf version of this document can be downloaded from www.skb.se Abstract The c. 1.80 Ga old bedrock in the Laxemar-Simpevarp area, which is the focus of the site investigation at Oskarshamn, is dominated by intrusive rocks belonging to the c. 1.86–1.65 Ga Transscandinavian Igneous Belt (TIB). However, the site investigation area is situated in between two c. 1.45 Ga old anorogenic granites, the Götemar granite in the north and the Uthammar granite in the south. This study evaluates the emplacement mechanism of these intrusions and their structural influence on the older bedrock.

  • Proposal for Morocco
    AFB/PPRC.16/12 19 March 2015 Adaptation Fund Board Project and Programme Review Committee Sixteenth Meeting Bonn, Germany, 7-8 April 2015 Agenda Item 6 h) PROPOSAL FOR MOROCCO AFB/PPRC.16/12 Background 1. The Operational Policies and Guidelines (OPG) for Parties to Access Resources from the Adaptation Fund (the Fund), adopted by the Adaptation Fund Board (the Board), state in paragraph 45 that regular adaptation project and programme proposals, i.e. those that request funding exceeding US$ 1 million, would undergo either a one-step, or a two-step approval process. In case of the one-step process, the proponent would directly submit a fully-developed project proposal. In the two-step process, the proponent would first submit a brief project concept, which would be reviewed by the Project and Programme Review Committee (PPRC) and would have to receive the endorsement of the Board. In the second step, the fully- developed project/programme document would be reviewed by the PPRC, and would ultimately require the Board’s approval. 2. The Templates approved by the Board (OPG, Annex 4) do not include a separate template for project and programme concepts but provide that these are to be submitted using the project and programme proposal template. The section on Adaptation Fund Project Review Criteria states: For regular projects using the two-step approval process, only the first four criteria will be applied when reviewing the 1st step for regular project concept. In addition, the information provided in the 1st step approval process with respect to the review criteria for the regular project concept could be less detailed than the information in the request for approval template submitted at the 2nd step approval process.

You have also learnt that the slow cooling of magma takes place in the deeper parts of the Earth and large size crystals are formed. On the contrary, magma undergoing rapid cooling in shallower depth or on the surface of the Earth yielded fine grained crystals. The rapid cooling of lava/melt molten rock on the surface of the Earth produces fine grained minerals or glass. The igneous rocks vary in grain size from very coarse, medium to fine grained or even glassy in hand specimen and under the microscope. Thus, igneous rocks display variety of textures. Thus, the term texture refers to physical appearance of a rock. In this unit we will discuss textures and structures of igneous rocks.

  • Psychosocial Impact of Scars Due to Cutaneous Leishmaniasis
    View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by Springer - Publisher Connector Bennis et al. Infectious Diseases of Poverty (2017) 6:46 DOI 10.1186/s40249-017-0267-5 RESEARCHARTICLE Open Access Psychosocial impact of scars due to cutaneous leishmaniasis on high school students in Errachidia province, Morocco Issam Bennis1,2,3,5* , Séverine Thys2, Hind Filali1, Vincent De Brouwere2, Hamid Sahibi4 and Marleen Boelaert2 Abstract Background: In Morocco, cutaneous leishmaniasis (CL) is usually known to be a slowly healing localized skin disease, but in some cases, it can lead to mutilating scars. The outbreak of CL due to Leishmania major in the Errachidia province in southeastern Morocco between 2008 and 2010 left many adolescents with permanent scar tissue on the face or other exposed body parts. We studied the psychosocial impact of CL on these young people. Methods: In 2015 we conducted a cross-sectional survey among high-school students living in boarding schools in two CL-endemic areas of Errachidia: Rissani and Tinejdad. A self-administered questionnaire elicited responses about general knowledge of CL and related scars. An open-ended question focused on the possible psychosocial effects associated with these scars. The quantitative data were analyzed with Epi Info™ and the text data with NVivo software. Results: Almost 20% of 448 respondents reported they had experienced a CL lesion and 87% said it could possibly or definitely lead to psychological consequences. The text analysis showed that girls more often than boys expanded on the negative psychological effects of CL. The students considered CL as “dangerous”, “serious”,and“deathly”, and said it sometimes led to extreme suicidal ideations.
