RESUMEN
INTRODUCTION: Ossification of the posterior longitudinal ligament in the spinal ligament compresses the spinal cord, causing various spinal nerve diseases. The ligament tissue is an important connective tissue in the joints, teeth, and spine, which, when torn and damaged, reduces the range of movement. CASE PRESENTATION: We report the treatment of periapical periodontitis and tooth preservation in a 41-year-old Japanese woman previously diagnosed with ossification of the posterior longitudinal ligament. She presented with widespread pain from the paranasal sinuses to the head caused by the onset of periapical periodontitis of the upper front tooth. DISCUSSION: The patient received an oral zinc supplement, which resolved periapical periodontitis over a 2-year follow-up period. CONCLUSION: The findings from this case imply that, when patients with ossification of the posterior longitudinal ligament develop periapical periodontitis, they should be tested for zinc deficiency.

"Hybrid exercise" utilizing combined electrical stimulation and voluntary muscle contraction has been developed as a muscle exercise method. Although our previous studies have confirmed the effectiveness of the procedure, the mechanisms of its efficacy still remain unclear. In the present study, we identified genes that are specifically expressed in disused muscles, using the semitendinosus muscle from patients who underwent anterior cruciate ligament (ACL) reconstruction. Preoperative exercise was performed by four ACL-injured patients, who were subjected either to hybrid exercise (n=2), electrical stimulation (n=1), or no electrical stimulation (n=1), in addition to standard weight training for 4 weeks. Cross-sectional area (CSA) of the semitendinosus muscle was measured before and after the exercise by magnetic resonance imaging (MRI). A piece of the semitendinosus muscle was isolated during the surgery, and comprehensive analysis of the gene expression in this sample was performed using DNA microarray analysis. CSA increased in size by 4.2 and 14.7%, respectively, after hybrid exercise, and by 1.4% after electrical stimulation. However it shrunk by 7.7% without electrical stimulation. DNA microarray analysis revealed that hybrid exercise was more effective at stimulating the expression of signal transduction-, transcription- and cytoskeleton-related genes in semitendinosus muscles than electrical stimulation alone. In particular, gene ontology analysis revealed that hybrid exercise induced significantly higher expression of eukaryotic translation initiation factor 5A (EIFSA), peroxisomal biogenesis factor 6 (PEX6) and histone cluster 1 H4 (HIST1H4), compared with electrical stimulation alone. The expression of signal transduction-, transcription- and cytoskeleton-related genes may play an important role in muscle bulk increasing mechanisms in hybrid exercise.

BACKGROUND: Physical inactivity is a risk factor for the development of non-alcoholic fatty liver disease (NAFLD). "Hybrid training", a training that involves both voluntary and electrical muscle contractions, causes beneficial alterations in muscles even after short durations of exercise. The aim of this study was to investigate the therapeutic efficacy of hybrid training in patients with NAFLD. METHODS: Thirty-five patients with NAFLD who were resistant to lifestyle counseling were assigned to a hybrid-training group (n = 12) or a control group (n = 23). In the hybrid-training group, quadriceps and hamstrings were contracted voluntarily or electrically for 19 min twice a week. In the control group, patients received lifestyle counseling. The therapeutic efficacy of the hybrid training was evaluated after 12 weeks of the intervention. RESULTS: Serum alanine aminotransferase (ALT) levels and hepatic steatosis grade were significantly decreased in the hybrid-training group compared to that of the control group (-14.1 ± 5.8 vs. 3.5 ± 5.4 IU/mL; P < 0.05, -0.67 ± 0.19 vs. 0.09 ± 0.06 grade; P < 0.01, respectively). No significant changes were seen between the two groups in skeletal muscle mass. The decreases in homeostasis model assessment of insulin resistance (HOMA-IR) value and in serum IL-6 levels were significantly greater in the hybrid-training group than in the control group (-6.2 ± 3.2 vs. 0.4 ± 0.6; P < 0.05, -3.1 ± 1.1 vs. 1.1 ± 0.5 pg/mL; P < 0.01, respectively). CONCLUSION: Hybrid training of voluntary and electrical muscle contractions improved hepatic steatosis and reduced insulin resistance and serum IL-6 levels in NAFLD patients who are resistant to lifestyle counseling.

Hesperidin (Hsp) is an abundant flavonoid in citrus fruits, and the oral administration of Hsp has been recently reported to suppress collagen-induced arthritis in mice. Therefore, we sought to determine whether alpha-glucosylhesperidin (Hsp-G), which is an Hsp derivative with enhanced water-solubility, is effective on treating arthritis in both mice and humans. Hsp-G was orally administered to mice with collagen-induced arthritis, and its effects were evaluated clinically and histologically. Oral administration of Hsp-G improved collagen-induced arthritis when administered before the onset of arthritis as well as when administered after its onset. A decrease in tumor necrosis factor-alpha production was found to cause this improvement. In the human study, 19 patients with rheumatoid arthritis (RA) were enrolled in a 12-week double-blind, placebo-controlled trial. Patients were administered beverages containing 3 g Hsp-G (n = 9) or placebo (n = 10) every morning for the duration of the 3-month trial. Additionally, patients received standard therapy from a physician every 4 weeks. As a result, 3 of 9 patients in the Hsp-G group improved, while only 1 of 10 patients in the placebo group improved; this was in accordance with the American College of Rheumatology criteria. The present study revealed that the food material Hsp-G was effective when administered with standard anti-rheumatoid therapy in ameliorating RA in mice and humans without any adverse effects and may improve the quality of life for patients with RA as a complementary/alternative medicine.
