Molecular Characterization, Assessment of Bread Wheat Genotypes Triticum aestivum L. Grown in Algeria using Microsatellites SSR Markers
Bread wheat (Triticum aestivum L.) genotypes was the most important cereal crop in Algeria. Twenty Algerian and introduce genotypes used in this study with a set of 18 wheat microsatellites molecular markers (Simple Sequence Repeat-SSR). This study is to use SSR marker to examine their utility in detecting DNA polymorphism and assessing genetic diversity. A total of 62 alleles were detected at 13 loci using 13 microsatellites primer pairs. The total numbers of alleles per locus (Na) ranged from 4 to 7 with a average of 4,7 alleles. The mean values of the number of effective alleles (Ne), and Shannon’s information index (I) were estimated at 3,425 and 1,31 respectively. The observed heterozygosity (Ho) values scored 1.00 at all loci, and the Polymorphic information content (PIC) values ranged from 0,60 at the locus WMC19 to 1,00 for the primer WMC25 averaging at 0.72. The mean observed heterozygosity (Ho) was slightly higher than the mean expected heterozygosity (He), determining a negative fixation index (F) at all loci, (average F=-0.45). Both groups of local bread wheat populations (Algerian) and those introduced from CYMMIT have almost the same number of alleles, (Na) 55,0 and 54,0 respectively. While the mean observed heterozygosity (Ho) was similar in the two groups, (He) was higher in Algerian genotypes, resulting in a negative fixation index (F) for both these two groups. The phylogenetic tree divided the 20 genotypes into two clusters. AMOVA revealed diversity within populations at 99% and between populations at 1%. The current populations were found to be highly structured. STRUCTURE analysis showed three groups at K =3. The first Group has the largest number of genotypes. The results proved the microsatellite markers SSR utility in detecting polymorphism due to the discrimination of various genotypes and estimating genetic diversity.
Development of a forest fire risk prevention plan (FFRPP) in the municipality of Dar Yaghmouracen, Algeria
Fires are the main problem affecting forests, as human presence in or near the forest largely determines the ignition and spread of fire. Therefore, the study of forest fire risk must be undertaken considering both the social and spatial aspects of fire risk through a specific approach. The proposed forest fire risk prevention plan (PPRIF) for the municipality of Dar Yaghmouracen, based on an assessment of hazards and stakes, delineates five risk zones. The high-risk and very high-risk zones represent 54.33% of the study area, while the low-risk zone accounts for 5.72%, and the moderate-risk zone covers 39.95%. Preventive measures are prescribed for each risk level, including the establishment of lookout posts, the clearing of brush along roadsides, and thinning and pruning activities. In light of the significant threat posed by wildfires in recent years, the ultimate goal of this initiative is to persuade the forestry administration to extend such preventive measures to other forests, in order to minimize human, environmental, and economic damage.
Anti-cancer effect of paclitaxel on canine mammary gland tumour in clinical cases of dogs.
Canine mammary gland tumors (CMGT) are among the most prevalent neoplasms in female dogs, with a higher incidence observed in those not spayed at an early age. Given this context, clinical cases of dogs with mammary tumors presenting at the Small Animal Clinics of Madras Veterinary College, Chennai, were studied to evaluate the anticancer effect of paclitaxel on CMGT in clinical cases. A total of forty-three CMGT-positive dogs were identified and underwent tumor excision following a standard surgical protocol. Tumor type and grade were confirmed based on established selection criteria. Of these, ten dogs were included in the study and received paclitaxel chemotherapy. Pre- and post-surgical levels of cancer-associated serum biomarkers, including CA15.3, CEA, COX-2, and HER-2, were assessed. Elevated levels of these biomarkers were noted in pre-surgical samples, while marked reductions were observed on days 21, 42, and 63 post-chemotherapy, suggesting a lack of metastasis and non-recurrence of mammary cancer. Clinical examinations confirmed the absence of cancer recurrence in the treated dogs up to day 120. In post-surgical cases of CMGT, paclitaxel was effective in preventing recurrence and metastasis of mammary cancer. However, further research using induced cancer models in animals, as well as clinical studies involving larger sample sizes and extended observation periods, is necessary to confirm paclitaxel's efficacy in CMGT-positive female dogs.
Use of GIS for mapping sensitivity to erosion using the MEDALUS approach: Application in the Boussaada sub- watershed, Algeria.
The sub-watershed of the Oued Bousaâda, covering an area of 2938.36 km², is part of the Hodna watershed, located southwest of Hodna in the high plateaus, and it is characterized by a semi-arid climate and the precipitation is highly irregular. These rains are associated with high variability. Soil erosion poses a serious environmental, agricultural, and social problem that affects and threatens this region. It is necessary to identify the most erosion-sensitive areas in this sub-watershed in order to determine priorities for mitigation actions. The objective of this study is to assess soil vulnerability to water erosion, develop a set of thematic maps (Vegetation Quality Map, Soil Quality Map, etc.), and create a database (DB) using an approach based on the MEDALUS (Mediterranean Desertification and Land Use) model and Geographic Information System (GIS). This mapping model is a tool intended to assist decision-makers in better managing water and soil resources, taking into account the expectations and needs of the rural population. By combining remote sensing with the analysis of factors known to affect the erosion process, such as climate, vegetation, soil, and demographics, a erosion sensitivity map has been created. The erosion risk mapping revealed that more than 75 % of the studied area showed high vulnerability to erosion. This map will be an essential tool for the socio-economic infrastructures of the region.
Antibacterial Efficacy and Toxicity Profiling of Some Centaurea Species from Algeria
This study evaluates the antibacterial activity of six nativeCentaurea species: C. sphaerocephala, C. tougourensis, C. napifolia, C. fragilis, C. papposa, C. solstitialis, and C. dimorpha. Three types of extracts: dichloromethane, ethyl acetate, and n-butanol, were tested for their ability to inhibit bacterial growth using the solid medium disk diffusion method at four different concentrations. The results confirm that extracts, particularly those derived from ethyl acetate, exhibit significant antibacterial activity against both Gram-positive and Gram-negative bacteria. Notably, C. papposa and C. napifolia demonstrated high efficacy against Staphylococcus aureus and Pseudomonas aeruginosa, suggesting their potential as natural antimicrobial agents. Additionally, the butanolic extract of C. papposa displayed no significant acute toxicity at a dose of 2000 mg/kg, indicating safety for further pharmacological research. This aligns with existing literature on Centaurea species, reinforcing their low toxicity potential in therapeutic applications. Histological findings revealed notable effects of the butanolic extract on the liver and lungs, highlighting the need for further investigation into the extract's safety profile and mechanisms of action. Future studies should focus on identifying the specific bioactive compounds responsible for the observed effects, enhancing our understanding of their therapeutic implications and ensuring safety and efficacy in clinical contexts.
