The forests in the eastern part of the park have suffered significant degradation of plant cover and a significant loss of biodiversity. Therefore, this study makes it possible to contribute to monitoring the dynamics of reconstitution of the plant cover based on the ecological characteristics and the distribution of epiphytes present in the Djapadji management sector. Floristic inventories were carried out. In the plots, all trees with a DBH ≥ 5 cm were counted and recorded for the study of the structure of plant formations, all species carrying an epiphyte were recorded and the epiphyte was identified. The analysis of the data presents a flora composed of 26 epiphytes distributed in 18 genera and 9 families, mainly present in mountain forests. The diversity of epiphytic plants is highest in mountain forests, followed by hydromorphic, secondary and gallery forests. Strict epiphytes and Hemiepiphytes are more present in the most preserved habitats, while accidental epiphytes are observed in reconstitution biotopes. The distribution of epiphytic plants allows us to affirm that the formerly anthropized forests of the Djapadji sector present a good dynamic of reconstitution.\u0000","PeriodicalId":7759,"journal":{"name":"American Journal of Life Sciences","volume":" 12","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141832706","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Infection in humans occurs when parasite larvae, released by freshwater gastropods, enter the skin through contact with infested water. Schistosomiasis is most prevalent in tropical and subtropical regions, particularly in poorer communities with no access to drinking water or adequate sanitation. Lack of hygiene and contact with contaminated water make children particularly vulnerable to infection. The aim of this study was to determine the prevalence of Shistosoma haemotobuim infestation in children aged 0-4 to 15 years in the locality of Matta-barrage. Microscopy using the sedimentation technique was used to identify Shistosoma haematobuim eggs in collected urine samples. Observation with a binocular magnifying glass was used to assess the cercarial emission rate. Of 155 urine samples analyzed, 69 were positive, representing a prevalence of 44.52%. The rate of Shistosoma haemotobuim cercariae was 21.03%. The prevalence of urogenital schistosomiasis is very high in this locality of Matta Barrage, as is the rate of cercarial transmission. A deworming campaign with Praziquantel is more than necessary.","PeriodicalId":7759,"journal":{"name":"American Journal of Life Sciences","volume":"164 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136377589","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, both types of materials have obvious shortcomings. Mg alloy degrades too rapid and the inhomogeneity degradation rate in the human environment, resulting in its mechanical properties rapidly declining and it cannot provide adequate support or fixing capacity. Fe alloy has a very slow degradation rate due to the good protective effect of its degradation products, resulting in similar problems to non-degradable material. In this situation, Zn alloys are often mentioned in recent years, because Zn is an essential trace element for the human body, and the standard potential of Zn is between Mg and Fe, so its degradation rate is excellent. At the same time, Zn-based alloy has become a new biodegradable biomedical material after Mg alloy and Fe alloy, and has been widely used in cardiovascular stents, bone implants and internal fixation devices, and gastrointestinal staplers. At present, there is no systematic research result on biodegradable biomedical Zn-based Alloy Materials, the research interests include composition design, processing and preparation, degradation principle, biocompatibility, mechanical properties in all aspects. This article reviewed the properties of Zn-based Alloy Materials compared with other typical alloys and pointed out the future development direction","PeriodicalId":7759,"journal":{"name":"American Journal of Life Sciences","volume":"17 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81535840","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
