Psychiatric disorders in general, and major depression and anxiety disorders in particular, account for a large burden of disability, morbidity and premature mortality worldwide. Omega-3 polyunsaturated fatty acids (PUFAs) have a range of neurobiological activities in modulation of neurotransmitters, anti-inflammation, anti-oxidation and neuroplasticity, which could contribute to psychotropic effects. Here we reviewed recent research on the benefits of omega-3 PUFA supplements in prevention against major depression, bipolar disorders, interferon-alpha-induced depression patients with chronic hepatitis C viral infection, and posttraumatic stress disorder. The biological mechanisms underlying omega-3 PUFAs' psychotropic effects are proposed and reviewed. Nutrition is a modifiable environmental factor that might be important in prevention medicine, which have been applied for many years in the secondary prevention of heart disease with omega-3 PUFAs. This review extends the notion that nutrition in psychiatry is a modifiable environmental factor and calls for more researches on prospective clinical studies to justify the preventive application of omega-3 PUFAs in daily practice.

Objective: We investigated the efficacy and toxicity of tailored-dose chemotherapy with gemcitabine and irinotecan for platinum-refractory/resistant ovarian or primary peritoneal cancer. Methods: We enrolled patients with ovarian or primary peritoneal cancer who received ≥2 previous chemotherapeutic regimens but developed progressive disease during platinumbased chemotherapy or within 6 months post-treatment. All patients received gemcitabine (500 mg/m 2 ) and irinotecan (50 mg/m 2 ) on days 1 and 8 every 21 days at the starting dose. The dose was increased or decreased by 4 levels in subsequent cycles based on hematological or non-hematological toxicities observed. The primary endpoint was progression-free survival (PFS), and secondary endpoints were disease control rate (DCR), overall survival (OS), and adverse events. Results: We investigated 25 patients who received 267 cycles (median 8 cycles/patient) between October 2008 and May 2011. Tailored-dose gemcitabine was administered up to the 5th cycle as follows: 1,000 mg/m 2 in 1 (4%), 750 mg/m 2 in 16 (64%), 500 mg/m 2 in 6 (24%), and 250 mg/m 2 in 2 patients (8%). The median PFS and OS were 6.2 months (95% confidence interval [CI]=2.7–10.7) and 16.8 months (95% CI=9.4–30.7), respectively. The DCR was 76%, and PFS was >6 months in 12 of 25 patients (48%). Grade 3 hematological toxicities included leukopenia (9.4%), neutropenia (11.2%), anemia (9.8%), and thrombocytopenia (1.1%).Grade 3/4 non-hematological toxicities did not occur except for fatigue in one patient. Conclusions Tailored-dose chemotherapy with gemcitabine and irinotecan was effective and well tolerated in patients with platinum-refractory/resistant ovarian or primary peritoneal cancer.

In this study, we examined the feasibility of using subzonal cell injection with electrofusion for interspecies somatic cell nuclear transfer (iSCNT) to produce sei whale embryos and to improve their developmental capacity by investigating the effect of osmolarity and macromolecules in the culture medium on the in vitro developmental capacity. Hybrid embryos produced by the electrofusion of fetal whale fibroblasts with enucleated porcine oocytes were cultured in modified porcine zygote medium-3 to examine the effects of osmolarity and fetal serum on their in vitro developmental capacity. More than 66% of the whale somatic cells successfully fused with the porcine oocytes following electrofusion. A portion (60~81%) of the iSCNT whale embryos developed to the two- to four-cell stages, but no embryos were able to reach the blastocyst stage. This developmental arrest was not overcome by increasing the osmolarity of the medium to 360 mOsm or by the addition of fetal bovine or fetal whale serum. Our results demonstrate that sei whale-porcine hybrid embryos may be produced by SCNT using subzonal injection and electrofusion. The pig oocytes partly supported the remodeling and reprogramming of the sei whale somatic cell nuclei, but they were unable to support the development of iSCNT whale embryos to the blastocyst stage.

Background: Transient severe myocardial ischemia in patients with coronary vasospasm impairs regional left ventricular (LV) relaxation which persists for several weeks. Methods: We studied 40 consecutive patients (17 women, 52±8) with vasospastic angina (VA) who had recurrent angina despite treatment with the conventional calcium channel blockers (CCBs) during the follow-up period. These 40 patients were registered and randomly assigned to either Waon therapy group or the high dose of CCBs therapy. In Waon therapy, the patients were treated with a far infrared-ray dry sauna at 60 degrees centigrade for 15 minutes and then kept on bed rest with a blanket for 30 minutes for 2 weeks. Strain imaging (SI) was acquired in the LV mid-papillary short-axis view and radial strain was measured using 2D speckle tracking echocardiography. The peak values of stain at the closure of aortic valve (A) and at the one third diastole duration (B) were measured. The SI-diastolic index (SI-DI) was determined as (A-B)/A 100%. The repeated SI study was conducted 1 weeks and 2 weeks in Waon therapy. Chest pain was scored by a numeric pain intensity rating scale. Results: The mean SI-DIs was 20±17% in the 45 territories perfused by the coronary arteries with spasm at baseline. The SI-DI significantly improved at 1 weeks (50±14%, p<0.001), and further improved after 2 weeks (77±10%, p<0.001). In contrast, the index did not improve in the high-dose CCBs therapy group. The pain score significantly decreased after 2 weeks of Waon therapy. Conclusion: The repeated Waon therapy improved the LV postischemic diastolic dysfunction and chest pain in patients with VA.
