Background： Consuming moderate amounts of lean red meat as part of a balanced diet valuably contributes to intakes of essential nutrients, in this study, we merged phenotypic and genotypic information to characterize the variation in lipid profile and sensory parameters and to represent the diversity among 15 cattle populations. Correlations between fat content, organoleptic characteristics and lipid profiles were also investigated. Methods： A sample of 436 largely unrelated purebred bulls belonging to 15 breeds and reared under comparable management conditions was analyzed. Phenotypic data -including fatness score, fat percentage, individual fatty acids （FA） profiles and sensory panel tests- and genotypic information from 11 polymorphisms was used. results： The correlation coefficients between muscle total lipid measurements and absolute vs. relative amounts of polyunsaturated FA （PUFA） were in opposite directions. Increasing carcass fat leads to an increasing amount of FAs in triglycerides, but at the same time the relative amount of PUFAs is decreasing, which is in concordance with the negative correlation obtained here between the percentage of PUFA and fat measurements, as well as the weaker correlation between total phospholipids and total lipid muscle content compared with neutral lipids. Concerning organoleptic characteristics, a negative correlation between fiavour scores and the percentage of total PUFA, particularly to n-6 fraction, was found. The correlation between juiciness and texture is higher than with flavour scores. The distribution of SNPs plotted by principal components analysis （PCA） mainly reflects their known trait associations, although influenced by their specific breed allele frequencies. Conclusions： The results presented here help to understand the phenotypic and genotypic background underlying variations in FA composition and sensory parameters between breeds. The wide range of traits and breeds studied, along with the genotypic informa

The management of neurosurgical pathologies has become a priority in our regions. Over the years the number of patients consulting in neurosurgical clinics continues to rise. Publications and studies of neurosurgical activities are rare in sub-Saharan Africa and almost inexistent in the Gambia in particular hence the impetus for this study： The Practice of Neurosurgery in EFSTH （Edward Francis Small Teaching Hospital） of Banjul, the Gambia. The objective of this study was to report on all the neurosurgical activities of the Neurosurgery unit of EFSTH of Banjul over an 18-month period. A retrospective study of all the neurosurgical activities of the EFSTH over a period of 18-month was carried out. Data were obtained from the medical records of the hospital categorized according to age groups. Consultation, admission, surgery, morbidity and mortality were evaluated. We included all patients managed in the Neurosurgery unit and excluded patients with insufficient data or missing folders. The Neurosurgery unit had a total of 2,038 patients giving an average of 113 patients seen per month of whom 399 （19.57%） were hospitalized and 127 （6.23%） benefitted from neurosurgical intervention. Morbidities and mortalities of 19 and 47 are respectively. Pediatric population with ages ranging from 0-9 years dominated in our admissions. Male： Female ratio was 2：1. The clinical features in our studies varied according to the diverse pathologies encountered in the study. Imaging was dominated by CT scan 168 cases （61%）, X-rays 102 cases （37%）. Pathologies seen in the Outpatient consultations were mainly degenerative pathology 938 （46%）, Trauma 391 （21%）, Hydrocephalus and other CNS （Central nervous system） Malformations 325 （16%）. Hospitalizations were mostly dominated by Trauma 300 （75.18%）, Hydrocephalus and other CNS Malformations 41 （9.77%）, degenerative disease 26 （6.52%）. Neurosurgical interventions were mainly trauma 47 （37%）, Hydrocephalus and other CNS Malformations 39 （31%）,
