RESUMEN
With the global shortages of animal protein foods, mycoprotein as a low-cost alternative source of protein by its high-protein and low-fat content has become a development trend. Lentinula edodes (L. edodes) is a healthy food with high protein and low fiber. This work evaluated the nutritional value of L. edodes mycelia, and determined the composition and contents of fatty acids and amino acids. Eleven saturated fatty acids (SFAs) and 12 unsaturated fatty acids (UFAs) were detected in the mycelia of L. edodes. The UFA content accounted for 75.7% and 73.1% of the total fatty acid content in the mycelia of strains 18 and 18N44, respectively. Linoleic acid was the major polyunsaturated fatty acid (PUFA) in the mycelia, accounting for 91.0% and 86.3% of the UFAs, respectively. The mycelia of the two strains contained 17 types of amino acids, and the essential amino acids were sufficient (357.92 ± 0.42 and 398.38 ± 4.52 mg/g pro, respectively), both close to the WHO/FAO reference protein pattern value. The most abundant essential amino acid was Lys, and the limiting amino acids were Met + Cys and Ile, respectively. The SRC values in the mycelia of the two strains were 68.07 and 54.86, and the EAAI values were 67.70 and 74.42, respectively, both being close to those of ovalbumin. It is concluded that L. edodes mycelia are rich in easily absorbed high-quality proteins and PUFAs, and can be used as a source for meat analog required by vegetarians. This study provides a scientific basis for the further utilization of mycelial resources.
RESUMEN
OBJECT: To explore the clinical feasibility of employing occlusion to treat basilar artery dissecting aneurysm. METHODS: One patient, male and 46 years old, suffered transient numbness and weakness on the right limbs. Cerebral angiography indicated basilar artery dissecting aneurysm. The patient underwent the stent-assisted coil embolization of aneurysm and the result is satisfactory. Digital subtraction angiography (DSA) reviews were performed at 1 month and 4.5 months, respectively after the operation and indicate that the basilar artery is unobstructed and there was no recurrence of the aneurysm. DSA review 1 year after the first treatment indicates the aneurysm recurrence, stent-assisted coils dense embolization of aneurysm was performed again and the result was satisfactory. Ten months after the second operation, DSA review found the basilar artery aneurysm recurrence again and occlusion of the basilar artery was performed. RESULTS: The basilar artery occlusion was effective. The bilateral posterior inferior cerebellar arteries and the bilateral posterior cerebral arteries are unobstructed. Five months of follow-up found that the patient recovered well. DSA reviews performed 5 months after occlusion indicate no recurrence of the aneurysm. CONCLUSIONS: Occlusion to treat basilar artery dissecting aneurysm is clinically feasible, but surgical indications should be considered strictly.
