Cost-effectiveness analysis comparing repetitive transcranial magnetic stimulation therapy with antidepressant treatment in patients with treatment-resistant depression in Japan.

Repetitive transcranial magnetic stimulation (rTMS) for patients with treatment-resistant depression (TRD) became covered by the National Health Insurance (NHI) in Japan since 2019. Although the evidence of rTMS for TRD is well established, the cost-effectiveness of rTMS versus antidepressants has not been thoroughly analyzed in Japan. Thus, we aimed to evaluate the cost-effectiveness of rTMS for TRD under the NHI system using a microsimulation model to compare the direct costs and quality-adjusted life years (QALYs).

Simultaneous monitoring of activity and heart rate variability in depressed patients: A pilot study using a wearable monitor for 3 consecutive days.

Introduction: Reduced activity and sleep-wake rhythm disturbances are essential features of depressive episodes. In addition, alterations in heart rate variability (HRV) have been implicated in depression. By using a wearable sensor that monitors 3-dimensional acceleration and HRV simultaneously, we examined the activity and HRV indices in depressive episode of mood disorders.

Emotion estimation using a wearable heart rate monitoring device in Asian elephants (Elephas maximus) during veterinary clinical procedures.

Fatal accidents in captive elephants occasionally occur because humans are unable to gauge elephants' emotions solely by their behavior. The intellectual capacity of elephants makes them capable of understanding circumstantial changes and associated emotions, allowing them to react accordingly. Physiological markers, such as heart rate variability, may be effective in determining an elephant's emotional state.

Global analysis of DNA methylation in early-stage liver fibrosis.

Background: Liver fibrosis is caused by chemicals or viral infection. The progression of liver fibrosis results in hepatocellular carcinogenesis in later stages. Recent studies have revealed the importance of DNA hypermethylation in the progression of liver fibrosis to hepatocellular carcinoma (HCC).

Estrogen inhibits transforming growth factor beta signaling by promoting Smad2/3 degradation.

Estrogen is a growth factor that stimulates cell proliferation. The effects of estrogen are mediated through the estrogen receptors, ERalpha and ERbeta, which function as ligand-induced transcription factors and belong to the nuclear receptor superfamily. On the other hand, TGF-beta acts as a cell growth inhibitor, and its signaling is transduced by Smads.

PPARgamma ligands suppress the feedback loop between E2F2 and cyclin-E1.

PPARgamma is a nuclear hormone receptor that plays a key role in the induction of peroxisome proliferation. A number of studies showed that PPARgamma ligands suppress cell cycle progression; however, the mechanism remains to be determined. Here, we showed that PPARgamma ligand troglitazone inhibited G1/S transition in colon cancer cells, LS174T.

[Identification and classification of beta-lactamases in clinical isolates of bacteria].

Emergence of bacterial resistance has rendered ineffective a number of previously valuable antibiotic treatments and now threatens the effectiveness of others. beta-Lactam resistance is no longer predominantly a hospital-treated problem; it has now become an important issue in community medicine. More than 100-beta-lactamases have been identified and classified according to their structure, substrate specificity, and whether they are chromosomal or plasmid-mediated.
