Real-Time Subcutaneous Arterial Navigation for Thinning of an Anterolateral Thigh Flap Using Photoacoustic Imaging and Projection Mapping: A Case Report.

Thinning of anterolateral thigh flap is challenging. Anatomical studies have shown variations in arterial branching patterns in the subcutaneous layer, which were suspected to be the reason for the high frequency of thinning failures. We attempted to visualize subcutaneous arterial courses preoperatively and perform thinning of perforator flaps using this information appropriately.

A multisite observational real-world study on the effectiveness of repetitive transcranial magnetic stimulation therapy for patients with treatment-resistant depression in Japan.

The objective of this study was to reveal the effectiveness of repetitive transcranial magnetic stimulation (rTMS) for Japanese patients with treatment-resistant depression (TRD) in clinical practice, based on real-world data from a nationwide multicenter observational study in Japan. Clinical data of patients with TRD treated with rTMS (NeuroStar TMS treatment system) under public insurance coverage were retrospectively collected from 21 institutes nationwide between June 2019 and December 2023. Depression severity was assessed by the 17-item Hamilton Depression Rating Scale (HAMD-17).

Altered genomic methylation promotes Staphylococcus aureus persistence in hospital environment.

Staphylococcus aureus can cause outbreaks and becomes multi-drug resistant through gene mutations and acquiring resistance genes. However, why S. aureus easily adapts to hospital environments, promoting resistance and recurrent infections, remains unknown.

Noninvasive visualization of the midline-crossing arterial variation in the deep inferior epigastric artery perforator flap using photoacoustic tomography for application in patients with abdominal scars.

Background: The importance of the subcutaneous arterial network crossing the midline in transverse abdominal flaps has been reported. Photoacoustic tomography can be used to noninvasively visualize subcutaneous vascular networks. We applied this novel technology preoperatively in patients undergoing breast reconstruction to detect individual variations in the midline-crossing arteries.

Physalin H, physalin B, and isophysalin B suppress the quorum-sensing function of by binding to AgrA.

The virulence of , including methicillin-resistant (MRSA), depends on the expression of toxins and virulence factors controlled by the quorum-sensing (QS) system, encoded on the virulence accessory gene regulator () locus. The aim of this study was to identify a phytochemical that inhibits Agr-QS function and to elucidate its mechanism. We screened 577 compounds and identified physalin H, physalin B, and isophysalin B--phytochemicals belonging to physalins found in plants of the Solanaceae family--as novel Agr-QS modulators.
