Several studies reported various crossmodal correspondences related to tactile features. These previous studies have investigated tactile-related correspondences through explicit matching or subjective evaluation tasks, which required participants to recognize relationships between tactile and other sensory features or rate tactile materials on scales with adjective labels related to visual or auditory features. However, these tasks are prone to occur the experimenter-expectancy effects and arbitrary categorization of tactile materials by the labels, making it difficult to assess implicit and non-arbitrary aspects of crossmodal correspondences.

The purpose of this study was to investigate the prognostic value of tumor VDT in resected lung SCCs.
Methods: In this study, subjects were 51 patients who underwent lobectomy for clinical stage I SCC of the peripheral lung at our institution between January 2006 and April 2020.
The TFDP1 gene codes for the heterodimeric partner DP1 of the transcription factor E2F. E2F, principal target of the tumor suppressor pRB, plays central roles in cell proliferation by activating a group of growth-related genes. E2F also mediates tumor suppression by activating tumor suppressor genes such as ARF, an upstream activator of the tumor suppressor p53, when deregulated from pRB upon oncogenic changes.

However, immune-related adverse events (irAEs) have been recognized as concerning side effects of ICIs.
Case Presentation: A 62-year-old man visited our hospital because of fever, dyspnea, and anorexia.
A 76-year-old woman was referred to our hospital due to abnormal chest radiography findings. Chest computed tomography (CT) revealed a nodule in the right lower lobe. Fluorodeoxyglucose-positronemission tomography (FDG-PET) showed abnormal accumulation in the nodule.

Methods: This study enrolled 284 patients with clinical T1 solid NSCLC who underwent anatomical lung resection. The Cox proportional hazard model was used to evaluate the prognostic impact of tumor volume doubling time (VDT) at disease-free survival (DFS) and cancer-specific survival (CSS).
Background: Although a well-acknowledged component of curative surgery for lung cancer, investigators have recently questioned the need for mediastinal lymph node dissection (MLND) in early-stage lung cancer cases. As such, the accurate prediction of N2 stage prior to surgery has become increasingly critical. But diagnostic biomarkers predicting N2 metastases are deficient, which are urgently needed.

Topical or systemic treatment with psoralen, such as 8-methoxypsoralen (8-MOP), followed by ultraviolet A (UVA) irradiation (PUVA therapy) is an effective phototherapy for early-stage MF. However, the efficacy of PUVA therapy for advanced-stage MF is not satisfactory, and the ideal combination partner for PUVA therapy has not yet been found.

The purpose of this study was to clarify the relationship between the results of the MDT and prognosis after lung cancer surgery.
Methods: Between May 2004 and September 2019, 1,434 patients underwent complete resection for lung cancer at our hospital.
The power-dependent transfer characteristics of spin currents generated at the interface of the permalloy/Pt bilayer device have been investigated over a wide power range from a few tens of milliwatt to 396 W. We built a high-power pulse excitation system for spin pumping, which achieves large electromotive force (EMF) values of 10 mV at 396 W excitation through the inverse spin Hall effect (ISHE) and demonstrates that the EMF generation after pulse excitation is very fast. Under strong pulse microwave excitation more than 80 W, the EMF spectrum exhibits an asymmetrical lineshape, which is well reproduced by simulations that take into account the fold-over effect due to the nonlinear ferromagnetic resonance excitation.

Herein, we describe a case of dedifferentiated RPLS successfully treated with an extended surgical approach with adjuvant chemotherapy. A 61-year-old male was referred to our hospital with a chief complaint of chest tightness.

The right mammary mass was diagnosed as breast cancer as a result of vacuum-assisted breast biopsy. Fluorodeoxyglucose-positron emission tomography( FDG-PET) showed no abnormal uptake in the lung fields.

Carinal resection and reconstruction was performed because of the tumor relapse after the treatment by argon plasma coagulator. Carinal resection was performed under the median sternotomy with reconstruction by the montage method.

Methods: The subjects of this retrospective study were 204 patients who underwent lobectomy and mediastinal lymph node dissection for clinical stage IA NSCLC. We analyzed the relationship between lymph node metastasis and clinicopathological factors, including the volume doubling time.
An anterior mediastinal tumor was detected by computed tomography (CT) in a 66-year-old man who complained of left flank pain, and the surgical treatment was performed. At surgery, partial resection of the pericardium was also conducted because the pericardial inversion was suspected. The histopathological diagnosis was dedifferentiated liposarcoma.

Although the occurrence of pneumothorax during pazopanib treatment has been recognized as an adverse event, there have been no reports of pneumothorax in patients treated with pazopanib. Here, we present the case of a 71- year-old male patient who developed pneumothorax during adjuvant pazopanib therapy after surgery for metastasized renal cell carcinoma.

The study aimed to evaluate the inter-rater and intra-rater reliability using 3-D scans from the Planmeca Emerald™ intra-oral scanner with Romexis Compare software for assessing preparations for preformed metal crowns (PMCs).
Methods: Three operators independently recorded 3-D scans and digitally measured the features of 30 PMC preparations on typodont primary teeth (# 75).
Background: Previous studies have reported the feasibility and efficacy of thoracoscopic anatomical sublobar resection under three-dimensional computed tomography (3DCT) simulation; however, its long-term outcomes have not been clearly established in primary lung cancer. This study aimed to evaluate the long-term outcomes of this technique.
Methods: We retrospectively reviewed data from 112 consecutive patients with selected clinical stage IA non-small cell lung cancer (NSCLC) who underwent thoracoscopic anatomical sublobar resection from 2004 to 2014.
A 78-year-old man was admitted to our hospital for further examination of a mass shadow in the left lower lobe noted on chest computed tomography. Because lung cancer was suspected, a left lower lobectomy was performed. During surgery, the left lower lobe and heart were so tightly adherent that the pericardial defect was not initially perceivable.

Background: Although several studies have been conducted on the patterns of recurrence in resected perihilar cholangiocarcinoma, the appropriate follow-up period after resection is still controversial.
Methods: Consecutive patients who underwent an R0 resection of perihilar cholangiocarcinoma between 2001 and 2014 were reviewed retrospectively, focusing on the time and site of initial recurrence. A Cox proportional hazards model was used for multivariate analysis.
Background: The subcategory "solid component of tumor" is a new criterion of tumor categories in the updated eighth edition of the TNM classification. Nevertheless, the predictors of lymph node metastasis among patients with clinical T1 adenocarcinoma, based on the TNM classification 8 edition, remain unclear. This study aimed to identify the preoperative predictors of lymph node metastasis in clinical T1 adenocarcinoma by comparing clinicopathological characteristics between the groups with and without lymph node metastasis.

Thoracoscopic segmentectomy is one of the most complicated surgeries. To perform the complex segmentectomies, pre-operative simulation and 3-dimensional multi-detector computed tomography( 3DCT) are both essential for safely performing operations and for securing adequate surgical margins.
