The world's population is aging. Pneumonia is the leading cause of death among the older adults, with aspiration pneumonia being particularly common. Aspiration pneumonia is caused by a decline in swallowing function.

Although motor coordination or motor skill learning are improved by taking vitamin D in the animal experiment, muscle function have not been estimated. Here we examined the effect of vitamin D administration on motor coordination and motor skill learning, muscle strength, and muscle volume in mice fed a vitamin D deficient diet. In mice fed a vitamin D deficient diet, serum calcium and 25(OH)D concentrations were measured.

A 72-year-old man was recovering at home after a stroke and consulted us because he wanted to resume taking food by mouth. He had tube feeding for 13 months after the stroke.

Herein, we report the case of a 101-year-old centenarian woman who recovered from extreme inactivity and general weakness, mainly through nutritional management at home, to understand instances of nutritional management in centenarians.

Patients swallowed thin liquid (Thin), thickened liquid (Thick), carbonated thin drink (C-Thin), and carbonated thickened drink (C-Thick) in random order. Penetration and/or aspiration were scored using the Penetration−Aspiration Scale (PAS).

Predisposing factors such as compromised host immune responses contribute significantly to NP pathogenesis. NP occasionally progresses to a more advanced and life-threatening state.

Although the mechanism of the formation of these deposits sometimes causes problems, such as dysphagia, asphyxia, or aspiration pneumonia, a 91-year-old male complained about difficulty of swallowing. He had a history of cerebral infarction and aspiration pneumonitis.

Interestingly, a recent clinical study found that administration of this agent is associated with lower risk of hip fracture independently of falling, suggesting its direct effect on bone tissues as well. AChE has been reported to be involved in osteoblast function, but the role of AChE on osteoclastogenesis still remains unclear.

We examined the effect of semaphorin 3A (SEMA3A) on dendritic processes of an osteocyte cell line, since in previous work we found it to be essential for promoting osteoblast differentiation.
Materials And Methods: Dendrite length was analyzed by Cellomics Array Scan VTI quantitatively in osteocyte-like cell line, MLO-Y4 cells.

T1R3 is a T1R class of G protein-coupled receptors, composing subunit of the umami taste receptor when complexed with T1R1. T1R3 was originally discovered in gustatory tissue but is now known to be expressed in a wide variety of tissues and cell types such the intestine, pancreatic β-cells, skeletal muscle, and heart. In addition to taste recognition, the T1R1/T1R3 complex functions as an amino acid sensor and has been proposed to be a control mechanism for the secretion of hormones, such as cholecystokinin, insulin, and duodenal HCO3(-) and activates the mammalian rapamycin complex 1 (MTORC1) to inhibit autophagy.

Patients And Methods: Study subjects included 18 patients having BRONJ stage 2 with sequestrum and 12 non-BRONJ patients with nearly equal clinical states of BRONJ stage 2. Patient characteristics, frequency of inciting factors of osteonecrosis, and treatment results were compared between BRONJ group and non-BRONJ groups.
Most clinicians throughout the world are probably unaware of the existence of masticatory muscle tendon-aponeurosis hyperplasia (MMTAH), potentially leading to misdiagnoses such as temporomandibular joint disorder (TMD). Here, we introduce this disease from the viewpoint of education. In February 2013, a 39-year-old woman presented with limited mouth opening.
