Providing user-understandable explanations to justify recommendations could help users better understand the recommended items, increase system’s ease of use, and gain users’ trust. A typical approach realize it is natural language generation. However, previous works mostly adopt recurrent neural networks meet ends, leaving potentially more effective pre-trained Transformer models under-explore...

L-Carnitine is used extensively in functional foods and food supplements; consequently, the control of its enantiomeric purity is of paramount importance. A new derivatization procedure and chiral gas chromatographic method with flame ionization detection, using a cyclodextrin based stationary phase, enables prompt, simple, and inexpensive screening of the enantiomeric ratio of L- and D-carniti...

We have characterized a stereospecific transport mechanism for L-dopa into human epidermal Langerhans cells (LCs). It is different from any other amino acid transport system. It is highly concentrative, largely pH-independent, and independent of exogenous Na+, glucose and oxygen, and fuelled by a renewable intracellular energy source inhibited by iodoacetate but not by arsenate. We propose that...

Primary hyperparathyroidism is defined by elevated parathyroid hormone and calcium levels, most usually caused a adenoma. Parathyroid adenomas are commonly detected in the neck or an ectopic site, seldom mediastinum. The adenoma can occur locations such as mediastinum, thymus, retro oesophagal area 6-16% of cases. We presented example 73-year-old woman who was found to have hypercalcemia during...

mg/l and 70 mm/h, respectively). Plasma creatinine was 1.3 mg/dl and the urea was 74 mg/dl. The 24-hour urine output was 3,100 ml with a glomerular filtration rate of 65 ml/min/1.73 m 2 . Urine antigen tests for Legionella pneumophila and Streptococcus pneumoniae were negative. Chest X-ray revealed bilateral diffuse alveolar infiltrates ( fig. 1 ). Respiratory tract infection was suspected and ...
