Abstract
At room temperature at stall, the flagellar motor of the bacterium Escherichia coli exerts a torque of ~1300 pN nm. At zero external load, it spins ~330 Hz. A robust method for studying the motor near zero load is reviewed here.

Abstract
We report on THz emission measurements and low temperature scanning laser imaging of Bi2Sr2CaCu2O8 intrinsic Josephson junction stacks. Coherent emission is observed at large dc input power, where a hot spot and a standing wave, formed in the "cold" part of the stack, coexist. By changing bias current and bath temperature, the emission frequency can be varied by more than 40%; the variation matches the Josephson-frequency variation with voltage. The linewidth of radiation is much smaller than expected from a purely cavity-induced synchronization. Thus, an additional mechanism seems to play a role. Some scenarios, related to the presence of the hot spot, are discussed.

Abstract
Abstract TLR ligands have been reported to promote DC maturation and enhance CD8+ CTL responses. We have demonstrated previously that CD4-8- DCs secreting TGF-beta stimulate CD4+ Tr1 cell responses. Here, we have assessed whether TLR4 and TLR9 signaling through LPS and CpG stimulation can convert CD4-8- DC-induced tolerance. We demonstrate that immature OVA-pulsed CD4-8- DCs cultured in medium with LPS (2 microg/ml) and CpG (5 microg/ml) for 8 h became mature DCs (DCOVA) with no TGF-beta secretion. CpG-treated, CD4-8- DCOVA-secreting IL-6/IL-15 induced IFN-gamma/IL-17-secreting/T-bet- and ROR-gammat-expressing CD4+ Th1/Th17, whereas LPS-treated CD4-8- DCOVA stimulated IFN-gamma-secreting/T-bet-expressing CD4+ Th1 responses. The former also significantly stimulated more efficient OVA-specific CD8+ T cell responses and antitumor immunity against OVA-expressing BL6-10OVA tumor cells than the latter (P<0.05). CpG-treated, CD4-8- DCOVA-stimulated CD4+ Th1/Th17 cell responses and antitumor immunity were found to be reduced by using neutralizing anti-IL-6, IL-15, and NK1.1 antibodies in wild-type C57BL/6 mice, IL-15R-/- mice for immunization, or CD4-8- (IL-6-/-) DCOVA for immunization in C57BL/6 mice. Interestingly, in vitro-generated CD4+ Th17 cells significantly enhanced LPS-treated, CD4-8- DCOVA-induced in vivo antitumor immunity via increasing CD8+ CTL responses (P<0.05), although they did not show any direct killing activity against tumor cells in vitro. In addition, prolonged 48 h CpG-treated CD4-8- DCOVA dramatically diminished its cytokine secretion, stimulatory effect, and antitumor immunity. Taken together, our data demonstrate an effect of conversion of tolerogenic DCs into immunogenic ones capable of stimulating antitumor immunity via activating CD4+ Th1/Th17 and NK cell responses by optimal CpG signaling, which may advance current understanding of the importance of TLR9 signaling in a DC-based cancer vaccine.

Abstract
Vacuum therapy (VT) utilizes negative pressure to distend the corporal sinusoids and to increase the blood inflow to the penis. Depending on its purpose, VT could be used as vacuum constriction device (VCD), with the aid of an external constricting ring which is placed at the base of penis to prevent blood outflow, maintaining the erection for sexual intercourse. Also, as a vacuum erectile device (VED), without the application of a constriction ring, just increases blood oxygenation to the corpora cavernosa and for other purposes. The emerging of phosphodiesterase 5 inhibitors (PDE(5)I) for the treatment of erectile dysfunction (ED) eclipsed VCD as therapeutic choice for ED; however, widespread usage of VED as part of penile rehabilitation after radical prostatectomy and other purposes rekindle the interest for VT. The underlying hypothesis is that the artificial induction of erections shortly after surgery facilitates tissue oxygenation, reducing cavernosal fibrosis in the absence of nocturnal erections, and potentially increases the likelihood of preserving erectile function. Due to its ability to draw blood into the penis regardless of nerve disturbance, VED has become the centerpiece of penile rehabilitation protocols. Herein, we reviewed the history, mechanism, application, side effects and future direction of VT in ED.

Abstract
Tumor cell apoptosis induced by radiation therapy results in apoptotic tumor cells and apparition of membrane blebs termed apoptotic bodies (APB). The immune responses induced by apoptotic tumor cells have been extensively studied. However, the role of APB in modulation of tumor immune responses is elusive. In this study, we induced apoptosis in 90% ovabumin-expressing EG7 tumor cells by in vitro irradiation (9,000 rad) of tumor cells with a subsequent cell culture for 9 hours. APB purified from irradiation-induced apoptotic EG7 cell culture supernatant by differential ultracentrifugation were vesicles with 50 to 90 nm in diameter and expressed apoptosis-specific Annexin V, 14-3-3, and Histone H3. We then investigated its potential modulation in DC(OVA)-induced T-cell responses and antitumor immunity. We found that EG7-derived APB were tolerogenic and capable of suppressing DC(OVA)-stimulated CD8+ CTL responses and antitumor immunity via its induction of CD8+ T-cell anergy and type 1 regulatory CD4+ T-cell responses. Analysis of apoptotic tumor cells and APB revealed the expression of membrane-bound transforming growth factor (TGF)-beta1 associated with irradiation-induced apoptosis formation, which is a result from activation of transcriptional factor NF-AT specific for TGF-beta1 promoters. Our data further elucidate that it is the membrane-bound TGF-beta1 expression on APB that contributes to its in vitro antiproliferative effect as shown by using neutralizing TGF-beta1-specific antibody. Administration of anti-TGF-beta1 antibody in vivo also blocked APB-mediated immune suppression of CD8+ CTL responses and antitumor immunity. Therefore, our study may have great impact in designing a combined radiation therapy with immunotherapy of cancer.
