Corncobs could serve as a substrate for citric acid production using solid state fermentation technique. The culture optimization concerning substrate concentration, culture duration, pH, temperature and substrate hydrolysis was carried out for maximum productivity of citric acid. Under the optimized conditions, 48.4 g of citric acid was produced from 1 kg dry corncobs. Biological evaluation was carried out for citric acid such as melanin synthesis inhibitory, anti-allergy, anti-bacterial, and hyaluronic acid production activities. The results showed that citric acid has potent melanin inhibitory activity, good inhibition for β-hexosaminidase release and potent stimulatory effect for the production of hyaluronic acid. These activities (melanin synthesis inhibitory, anti-allergy and hyaluronic acid productive activities) of citric acid have been reported for the first time.

Difficulty:★★ To help others, you don’t have to be an efficient expert in the art, and the main thing is the intention. You may be crude and clumsy, wasteful and ineffective, but if you sincerely try to help, your attempt produces nothing but good. The one you are trying to help knows your intention and is strengthened and encouraged by the magic of your sharing.

Meningiomas account for 25% of spinal tumors, and they are often located in the thoracic spine. The ossified subtype is even rarer, and those with hematopoiesis are rarely described. The mechanism of bone formation has not yet been clarified. A case of ossified spinal meningioma with hematopoiesis occurring in a 78-year-old woman is described. Magnetic resonance imaging revealed a lesion with a dural tail sign at the T9 level located dorsal to the spinal cord. Computerized tomography revealed a high density lesion, as high as the bone signal. Total resection was performed, and the symptoms improved. Pathological findings revealed many psammoma bodies (PBs), bone formation, and bone marrow with hematopoiesis. Both PBs and bone seemed to be based on the same background of calcified structures. This report is the second dealing with ossified spinal meningioma with hematopoiesis. The hardness of the tumor can make the operation more difficult, so that the operation should be performed carefully to avoid injuring the spinal cord.

It’s difficult to find a piece of clothing as widely worn and loved as jeans. But why? Jeans were designed as work-wear for labourers in America’s Western states in the late 19th century. When a tailor called Jacob Davis was asked to make a pair of sturdy trousers for a local woodcutter, he had the idea of reinforcing them with rivets. They proved extremely
