In Guinea, traditional rice varieties are the most widely cultivated in rural areas despite their low yield and high susceptibility to iron toxicity. Moreover, the introduction of new improved varieties tolerant to iron toxicity poses a serious threat to the preservation of the genetic resources of these traditional varieties, whose genetic diversity remains poorly known. The present study therefore aims at a better valorisation of these local rice cultivars through the evaluation of their agromorphological diversity and the identification of genotypes potentially tolerant or resistant to iron toxicity. Thus, 90 accessions collected in the regions of Kindia and Macenta and six controls susceptible or resistant to iron toxicity (AZUCENA, BouAKE 189, CK 73, IR64, NERICAL 19 and AURYLUX 6) were evaluated in three replicate alpha lattice designs in two sites (Sérédou and Kilissi) using 16 agromorphological traits. The results showed significant agromorphological variability of the traditional accessions at both sites for all qualitative and most quantitative traits studied. In addition, 30 local cultivars expressed similar or higher grain yields than the resistant or tolerant controls at both sites, of which 12 were found to be stable at both sites. Of the 12 cultivars identified, five were resistant and seven tolerant to iron toxicity. These 12 accessions could be used in the varietal improvement of lowland rice in Guinea Conakry.

American Journal of Plant Sciences 2022年第6期13卷 872-883页

In Burkina Faso, sweet grain sorghum [Sorghum bicolor (L.) Moench] is generally cultivated in association with several other types of sorghum. However, the lack of information on the genetic relationship between this sorghum and grain sorghum as well as sweet stalk sorghum hinders the efficient management of its genetic resources. Thus, 34 sorghum accessions consisting of 14-grain sorghum, 10-sweet stalk sorghum, and 10 sweet grain sorghum were evaluated using 15 nuclear microsatellites markers (SSRs) to determine their genetic relationship. Results revealed significant genetic diversity within each sorghum type and a significant index of genetic differentiation per pair of sorghum types (0.017) between sweet grain sorghum and sweet stalk sorghum. The minimum Nei distance was also high (0.12) between these two sorghum types. Sweet grain sorghum indeed showed the lowest values of theoretical heterozygosity (0.35), of observed heterozygosity (0.13). Structuring of the accessions of the three types of sorghum cultivated in two distinct groups, one of grain sorghum and sweet stalk sorghum and another consisting of accessions of grain sorghum and sweet grain sorghum was also obtained. The low differentiation observed would suggest greater genetic proximity between the three types of sorghum. The differences observed would be more of a physiological and biochemical nature. These results could contribute to better management of the genetic resources of sweet grain sorghum.

Traumatic Neglected Antero-Medial Knee Dislocation: Case Report

Open Journal of Orthopedics 2024年第9期14卷 421-426页

Introduction: Neglected knee dislocation is an unusual injury, only a few cases have been reported in the literature. The circumstances of onset are generally an unnoticed knee dislocation in a polytrauma context or a delay in consultation after the initial trauma. Presentation of case: We report the case of a 48-year-old female patient who sustained a knee injury during a domestic accident. Initial treatment was traditional and was followed for 3 years. She then consulted hospital, where a neglected knee dislocation was identified and treated with femorotibial arthrodesis. Discussion and conclusion: The treatment options of neglected knee dislocation include open reduction and fixation, arthrodesis and total knee arthroplasty. That the choice depends on the old unreduced of dislocation.

Garcinia kola Heckel, called “petit cola” in Côte d’Ivoire and “bitter kola” in Nigeria, is a Non-Timber Forest Product of great socioeconomic importance. Unfortunately, this species is threatened due to overexploitation and deforestation. This study tested the effect of leaf area on stem cuttings to regenerate vegetatively in a non-mist poly-propagator without using exogenous hormones. Three stem cuttings types: greenwood, softwood and hardwood (12 - 15 cm in length) were collected from 24-month years old seedlings. The two top leaves of each cutting type were conserved at different leaf area: 0 cm2, 28.25 cm2, 56.5 cm2, 84.75 cm2 and 113 cm2 (entire leaf area). Observations were made on rooting, sprouting and leafing abilities of cuttings depending to treatments applied. Results showed that all cutting types have presented good ability to shooting and rooting. Cuttings with 113 cm2 leaf areas presented the best rooting (94.44% ± 2.42%) and shouting (95.55% ± 2.42%) percentage and longest primary root length (12.03 ± 0.50 cm). Hardwood, softwood and greenwood cuttings with 113 cm2 leaf area had the best rooting percentage (96.66% ± 3.33%, 96.66% ± 5.77% and 90.00% ± 5.77% respectively). The longest primary root length (13.50 ± 0.97 cm) was observed to greenwood cuttings with 113 cm2 leaf area. Regenerated plants in the forest presented well survival percentage (96.66%). This study shows that it is possible to regenerate entire plants by cuttings without using external hormones in non-mist poly-propagator.

Management of Maxillofacial Gunshot Trauma in the Stomatology and Maxillofacial Surgery Departments of ouagadougou

引用

Open Journal of Stomatology 2023年第10期13卷 342-352页

作者： Mathieu Millogo Motandi Idani Arsène Coulibaly Michel Fabien Dargani mahamadi Sanfo Tarcissus Konsem Department of Stomatology and Maxillofacial Surgery Tengandogo University Hospital Ouagadougou Burkina Faso Department of Stomatology and Maxillofacial Surgery Yalgado Ouédraogo University Hospital Ouagadougou Burkina Faso Department of Stomatology and Maxillofacial Surgery Ouahigouya Regional University Hospital Ouagadougou Burkina Faso

Introduction: Maxillofacial ballistic trauma is a serious injury that is difficult to manage, with significant complications and after-effects. The authors report their experience in managing this type of trauma in the context of insecurity linked to terrorism. Patients and Methods: This was a descriptive cross-sectional study with retrospective data collection covering the period from January 1, 2018 to December 31, 2022 in the stomatology and maxillofacial surgery departments of the university hospitals of ouagadougou. Results: In 5 years, 52 patients were collected, i.e. 10.4 cases per year. The mean age of the patients was 31.46 ± 15.41 years, and the sex ratio was 3. In 67.31% of patients, these injuries were the result of shootings during terrorist attacks. The jugal (36.54%) and chin (32.69%) regions were the most affected. The mandible (36.54%) and zygomatic bones (28.85%) were the most injured bones in these traumas. All patients underwent surgical treatment, and 25% suffered secondary complications. All patients retained at least one sequela. Conclusion: Maxillofacial injuries caused by ballistic trauma are true emergencies that can be life-threatening and functionally disabling. Their management is delicate and the outcome is uncertain, hence, the prevention is important.
