Myxofibrosarcoma is the most common soft tissue sarcoma that occurs in late adult life,mainly occurring in the lower extremities and trunk. However, head and neck myxofibrosarcomais extremely rare. The most reliable treatment of adult soft tissue sarcoma is surgical resectionwith negative margin. A 79-year-old man presented with a left cheek mass first detectedsix months ago. The pathologic report of the mass showed that it was myxofibrosarcomaand consequently postoperative radiotherapy was done. However, distant and locoregionalmetastasis occurred postoperatively. We report this case with a brief review of literature.

Glomanigiopericytoma is a rare vascular neoplasm with a perivascular myoid phenotype. It is rarely found in the neck but most commonly in the nose and paranasal sinuses. We experienced a case of 72-year-old man who presented a 5-year history of a right neck mass. The pathologic diagnosis was glomangiopericytoma. We removed the mass transcervically and the patient showed no postoperative problem. We report this case with a review of literature. Korean J Otorhinolaryngol-Head Neck Surg 2017;60(11):584-6

Axillary node metastasis of head and neck squamous cell cancer is uncommon. We experienced a case of 68-year-old man who presented as 6- months history of a hoarseness. The pathologic diagnosis was squamous cell carcinoma of glottis. He was treated by conventional radiotherapy 6520 cGY for 6 weeks. However, at 3 weeks after completion of radiotherapy, ipsilateral axillary metastasis was detected and progressed to death. We report this case with a review of literature.

A porphyrinic metal-organic framework (PMOF) known as PCN-222 (Zn) was surface-modified by the molecular Re(I) catalyst through anchoring to the PMOF with carboxylate to form a new type of MOF hybrid photocatalyst. The porphyrinic MOF-based hybrid (PMOF/ Re(I)) prepared with an archetypical CO<sub>2</sub> reduction catalyst, (L)ReI (CO)<sub>3</sub>Cl (Re(I); L = 4,4′-dicarboxylic-2,2′-bipyridine), in the presence of 3 vol% water produced CO with no leveling-off tendency for 59 h to give a turnover number of ≥1,133 ± 142 (639 ± 80 μmol h-1 (g MOF)-1). The high catalytic activity should mainly arise from efficient exciton migration and funneling from photoexcited porphyrin linkers (ZnPs*) to the periphery Re(I) catalytic sites, which is in line with the observed fast exciton (energy) migration (~(20-30 ps) between porphyrin photoreceptors and funneling into Re(I) catalytic centers in Re(I)-doped PMOF sample.

Background and Objectives Salt-taste threshold can influence salt appetite, and is thought to be another marker of sodium intake. Many studies have found an association between sodium intake and blood pressure. The aim of this study was to compare the salt-taste threshold and salt intake between hypertensive and normotensive groups. Subjects and Method One hundred twenty volunteers (51 men and 69 women) who did not take antihypertensive medications were evaluated. First, a questionnaire, which included questions regarding demographic information and preference of salty taste, was conducted, and 24-hour ambulatory blood pressure was checked. Then salt taste threshold was measured by assessing the ability of the subjects to discern the taste of salt in graded solutions of saline. Lastly, 24-hour urinary sodium was measured in a 24-hour urine collection. Results The salt taste threshold and taste preference for salt were slightly higher in hypertensive group. There was slightly higher salt intake measured as 24-hour urinary sodium in the hypertensive group, compared with the normotensive group. However, there were no significant differences in salt taste threshold, preference of salty taste, and salt intake between the normotensive and the hypertensive groups. Conclusion The threshold of salt taste was not related to sodium intake and hypertension status. These results suggest that the development of hypertension depends on the complex interaction of factors such as genes and environmental factors rather than sensory factors like taste threshold and taste preference.
