Erectile dysfunction (ED) is increasingly prevalent in Japan, exceeding 30%, and increasing with age. Unhealthy lifestyle habits, obesity, insufficient exercise, and smoking have been implicated in its pathogenesis, along with endothelial dysfunction of the corpora cavernosa and impaired blood flow to the penis considered underlying factors. However, the current treatments are limited to Phosphodiesterase-5 (PDE5) inhibitors. ED is the primary symptom of andropathy. This study reports the clinical efficacy of human stem cell-conditioned medium cream for ED treatment. Ten men without underlying diseases suspected of andropause with ED (mean age 43.2 ± 4.4 y, Hb 15.2 ± 0.6 gm/dL, AST/ALT 30.2/37.9 ± 12.4/14.0, eGFR 82.7 ± 12.4 mL/min/1.73 m2) were targeted. The cream was applied twice daily to the genital and scrotal areas. The erectile hardness score (EHS), International Index of Erectile Function-5 (IIEF-5), and Aging Male Symptoms (AMS) scale were used to evaluate the participants before and 30 days after use, and the results were compared using paired t-tests. The post-use qualitative opinions were collected through interviews. Significant improvements were observed compared to baseline in the IIEF-5 (11.8 ± 4.6→17.2 ± 5.1, P < 0.001), and AMS (46.3 ± 6.7→37.6 ± 5.3, P < 0.001) scores post cream use. EHS did not show a statistically significant difference, but a trend towards improvement was observed. Qualitative feedback included increased morning erection, improved maintenance of erection during intercourse, and reduced post work fatigue. Human stem cell-conditioned medium contains endothelial growth factors that potentially contribute to the improvement of ED and andropause by enhancing corporal endothelial function. Future studies should include control groups to further investigate the efficacy of these treatments.

The matrix metalloproteinase (MMP) stromelysin-3 (ST3) has long been implicated to play an important role in extracellular matrix (ECM) remodeling and cell fate determination during normal and pathological processes. However like other MMPs, the molecular basis of ST3 function in vivo remains unclear due to the lack of information on its physiological substrates. Furthermore, ST3 has only weak activities toward all tested ECM proteins. Using thyroid hormone-dependent Xenopus laevis metamorphosis as a model, we demonstrated previously that ST3 is important for apoptosis and tissue morphogenesis during intestinal remodeling. Here, we used yeast two-hybrid screen with mRNAs from metamorphosing tadpoles to identify potential substrate of ST3 during development. We thus isolated the 37 kd laminin receptor precursor (LR). We showed that LR binds to ST3 in vitro and can be cleaved by ST3 at two sites distinct from where other MMPs cleave. Through peptide sequencing, we determined that the two cleavage sites are in the extracellular domain between the transmembrane domain and laminin binding sequence. Furthermore, we demon strated that these cleavage sites are conserved in human LR. These results together with high levels of human LR and ST3 expression in carcinomas suggest that LR is a likely in vivo substrate of ST3 and that its cleavage by ST3 may alter cell-extracellular matrix interaction, thus, playing a role in mediating the effects of ST3 on cell fate and behavior ob- served during development and pathogenesis.

Pivotal informal organizations, above all the G20, the G7 and. the BRICS, have accumulated growing power in recent years. At a basic level, informal organizations differ from the formal institutions such as the UN and the 1MF in a number of key ways： membership structure; foundational or legitimizational character and level of bureaucracy. What are the implications of this phenomenon for global governance？ What does this shift from a hub club to a focal point network imply for innovation in modes of cooperation？ The author has participated in numerous such summits, in his capacity as Prime Minister of ltaly and President of the European Commission, and shares his first-hand thoughts.

Tega-numa （Lake Tega） is one of the eutrophic lakes in Japan. For the improvement of water quality in Lake Tega, the North- chiba Water Conveyance Channel was constructed in 2000, which transfer water from Tone River into the lake. After 2000, the dominant species of diatoms, mainly Cyclotella sp., have been replacing blue-green algae, mainly Microcystis aeruginosa in Lake Tega. This transition of dominant species would be due to the dilution, but the detail mechanism has not been understood yet. This study examined the relationship between phosphorus fluctuation caused by river water dilution to Lake Tega and dominance of algal species, M. aeruginosa or Cyclotella sp. based on the single-species and the mixed-species culture experiments. The single-species culture experiment showed that the half-saturation constant and uptake rate of phosphorus were one order lower and seven times higher for M. aeruginosa than those for Cyclotella sp. These findings implied that M. aeruginosa would possess a potential for the growth and survival over Cyclotella sp. in the phosphorus limited condition. The superiority of M. aeruginosa was reflected in the outcome of the mixed-species culture experiment, i.e., dominance of M. aeruginosa, even phosphorus concentration was lowered to 0.01 mg-P/L. Therefore, it could be concluded that the decrease in phosphorus concentration due to the river water dilution to Lake Tega would be interpreted as a minor factor for the transition of dominant species from M. aeruginosa to Cyclotella sp.

Ba ckground The prognosis of elderly patients with chronic total occlusion (CTO) and diabetes mellitus (DM) treated with percutaneous coronary intervention (PCI) is not known. Objective To investigate the effect of diabetes on long-term follow-up of CTO after PCI in elderly *** A total of 153 elderly patients (age > 65 years old) with CTO lesions which were successfully treated with PCI were enrolled. Fifty one patients with diabetes and 102 without diabetes were compared for long-term outcomes (mean follow up: 36 ±12 months). Major adverse cardiac events (MACE) which include death, myocardial infarction or target lesion revascularization (TLR) were considered as a combined endpoint. Results The combined endpoint occurred in 29.4% of diabetes patients, and 11.3% of the patients without diabetes (P < 0.05). The Cox proportional hazards model identified: drug eluting stent (DES) or bare metal stent (BMS) (HR: 0.13, 95% confidence interval (95%CI): 0.03–0.62, P = 0.004), DM(HR: 6.69, 95% CI: 1.62–15.81, P = 0.01) and final minimal lumen diameter (MLD) (HR: 0.37, 95% CI: 0.13–0.90, P = 0.03 ) as independent predictors of MACE, DM with renal impairment (HR: 6.64, 95% CI: 1.32–33.36, P = 0.02), HBA1C on admission (HR: 1.79, 95% CI: 1.09–2.94, P = 0.02), as independent predictors of MACE at long term follow-up. Conclusions The study demonstrates that DMis a predictive factor for MACE in elderly CTOpatients treatedwith PCI, type of stent, final minimal lumen diameter and DMwith renal impairment, and HBA1C level on admission are predictors of MACE.
