[Pt(NCN)MeCN] (NCN = 1,3-di(2-pyridyl)benzene, MeCN = acetonitrile) forms oligomers in the ground state due to metallophilic interactions, and a Pt-Pt bond is formed with photoexcitation. Ultrafast excited-state dynamics of the [Pt(NCN)MeCN] dimer in acetonitrile is investigated by femtosecond time-resolved absorption (TA) and picosecond emission spectroscopy. The femtosecond TA signals exhibit 60 cm oscillations arising from the Pt-Pt stretching motion in the S dimer.

Between April and September 2023, 41 patients received WAVE under local anesthesia as day surgery at the outpatient department in our institution. The mean age as of operation was 78.

- Researchers investigated whether SARS-CoV-2 RNA can be found on the skin of COVID-19 patients by analyzing skin surface lipids (SSLs) collected from their faces.
- Using RT-PCR, they found that 84.6% of samples tested positive within 5 days of symptom onset, while only 30.4% tested positive between 6-10 days.
- The study also revealed an increase in specific genes related to the immune response in the skin samples, highlighting a new method for detecting the virus and studying its impact on human health non-invasively.
Porphyrins have emerged as highly effective photosensitizers in the field of photodynamic therapy (PDT) because of their high singlet oxygen generation efficiency. However, most porphyrin derivatives do not have adequate water solubility and cell membrane permeability suitable for use in PDT. In addition, they frequently suffer from low durability under photoirradiation.

The present study evaluated the oncological outcomes of MDRT on the basis of the PSADT in oligo-recurrent prostate cancer patients.
Patients And Methods: We retrospectively reviewed clinical data of 35 MDRTs for 29 patients at the Kitasato University Hospital, targeting oligometastatic prostate cancer developed after radical treatment for non-metastatic prostate cancer.
