Case report: Duplication of the gene is a novel cause of nesidioblastosis: evidence from a case with Silver-Russell syndrome-like phenotype related to chromosome 7.

Silver-Russell syndrome (SRS) is a syndrome characterized by prenatal and postnatal growth retardation, facial features, and body asymmetry. SRS is often complicated with hypoglycemia, whose etiology is unclear. We describe the clinical course of 25-year-old man with hypoglycemia.

Starvation changes the pre-rRNA accumulations in Caenorhabditis elegans.

The precursor rRNA (pre-rRNA) processing pathway in Caenorhabditis elegans remains unidentified. We have determined the cleavage site within the internal transcribed spacer 2, which generates pre-rRNA f of 5.8S rRNA and pre-rRNA g of 26S rRNA.

Liver transplantation for gastroenteropancreatic neuroendocrine liver metastasis: optimal patient selection and perioperative management in the era of multimodal treatments.

Gastroenteropancreatic neuroendocrine tumors (NET) often metastasize to the liver. Although curative liver resection provides a favorable prognosis for patients with neuroendocrine liver metastasis (NELM), with a 5-year survival rate of 70-80%, recurrence is almost inevitable, mainly in the remnant liver. In Western countries, liver transplantation (LT) has been performed in patients with NELM, with the objective of complete removal of macro- and micro-NELMs.

The Significance of Longitudinal Psoas Muscle Loss in Predicting the Maintenance Efficacy of Durvalumab Treatment Following Concurrent Chemoradiotherapy in Patients with Non-Small Cell Lung Cancer: A Retrospective Study.

Sarcopenia assessed at a single time point is associated with the efficacy of immunotherapy, and we hypothesized that longitudinal changes in muscle mass may also be important. This retrospective study included patients with non-small cell lung cancer (NSCLC) who received durvalumab treatment after concurrent chemoradiotherapy (CCRT) between January 2017 and April 2023. Muscle loss and sarcopenia were assessed based on the lumbar skeletal muscle area.

Unraveling the influence of TTF-1 expression on immunotherapy outcomes in PD-L1-high non-squamous NSCLC: a retrospective multicenter study.

Introduction: Several studies explored the association between thyroid transcription factor-1 (TTF-1) and the therapeutic efficacy of immunotherapy. However, the effect of TTF-1 on the therapeutic efficacy of programmed death-1 (PD-1) inhibitor/chemoimmunotherapy in patients with non-squamous non-small cell lung cancer (non-Sq NSCLC) with a programmed death-ligand 1 (PD-L1) tumor proportion score of 50% or more who are highly susceptible to immunotherapy remains unresolved. Therefore, we evaluated whether TTF-1 has a clinical impact on this population.

Clinical Implications and Risk Factors of Dilatation of Remnant Pancreatic Duct at 1 Year after Pancreatoduodenectomy: A Prospective, Japanese, Multicenter, Observational Cohort Study (DAIMONJI Study).

Background: To determine the precise frequency of main pancreatic duct (MPD) dilatation within the remnant pancreas at 1 year after pancreatoduodenectomy (PD) and its clinical implications, a prospective multicenter cohort study was performed in patients without MPD dilatation before PD (registry number: UMIN000029662).

Study Design: Between October 2017 and July 2020, patients with an MPD diameter less than 3 mm who were planned to undergo PD for periampullary lesions at 21 hospitals were enrolled. The primary endpoints were frequency of MPD dilatation at 1 year after PD, and the relationship between MPD dilatation and pancreatic endo- and exocrine function, nutritional status, and fatty liver.

Control of Optical Reflection in CaMgWO by Co and Mo Doping.

To develop novel inorganic red pigments without harmful elements, we focused on the band structure of Ca(Mg, Co)WO and attempted to narrow its bandgap by replacing the W sites in the host structure of Mo. CaMgCoWMoO (0.10 ≤ ≤ 0.

Comparison of the outcomes of Pneumocystis jirovecii pneumonia in rheumatoid arthritis patients treated with and without biologics.

Background: To investigate the outcomes of Pneumocystis jirovecii pneumonia (PCP) between patients with rheumatoid arthritis (RA) treated with and without biologics before PCP onset.

Patients And Methods: We retrospectively included rheumatoid arthritis (RA) patients with PCP treated with and without biologics before PCP onset. The primary endpoints were 30-day and 180-day survival rates, and the secondary endpoint was severe PCP, including in-hospital death, intensive care unit admission, and requirement of respiratory support during hospitalization.

Pancreatic RECK inactivation promotes cancer formation, epithelial-mesenchymal transition, and metastasis.

RECK is downregulated in various human cancers; however, how RECK inactivation affects carcinogenesis remains unclear. We addressed this issue in a pancreatic ductal adenocarcinoma (PDAC) mouse model and found that pancreatic Reck deletion dramatically augmented the spontaneous development of PDAC with a mesenchymal phenotype, which was accompanied by increased liver metastases and decreased survival. Lineage tracing revealed that pancreatic Reck deletion induced epithelial-mesenchymal transition (EMT) in PDAC cells, giving rise to inflammatory cancer-associated fibroblast-like cells in mice.

Color Controllable Inorganic Pigments with Ce as a Color Source.

The BaRECeTaO (RE = La, Gd, Y; 0 ≤ ≤ 1) pigments were synthesized by a conventional solid-state reaction method to develop environmentally friendly reddish inorganic pigments. The host was the double-perovskite-type BaRETaO (RE: rare-earth elements), and the color source was Ce. All BaRECeTaO samples were obtained in a single-phase form as solid solutions.

Safety and efficacy of neoadjuvant chemoradiotherapy with moderately hypofractionated intensity-modulated radiotherapy for resectable pancreatic cancer: A prospective, open-label, phase II study.

Background: Resectable pancreatic cancer (RPC) is potentially resectable on admission, and the impact of neoadjuvant therapy on these tumors is controversial. Moreover, the safety and efficacy of neoadjuvant chemoradiotherapy with moderately hypofractionated intensity-modulated radiation therapy (NACIMRT) for RPC have not been studied. Here, we conducted a phase II study to evaluate the safety and efficacy of hypofractionated NACIMRT for RPC.

Preoperative Endoscopic Minor Papilla Sphincterotomy for Pancreas Divisum in a Patient with Pancreatic Cancer Who Underwent Laparoscopic Distal Pancreatectomy.

Background: Pancreas divisum (PD) is a congenital anomaly that occurs due to failure of fusion of the dorsal and ventral pancreatic ductal systems. In PD, pancreatic juice drains mainly through the minor papilla via the dorsal duct, leading to high intraductal pressure, which can cause pancreatitis. We report a case of PD that underwent preoperative decompression using endoscopic minor papilla sphincterotomy (EMPS) before laparoscopic distal pancreatectomy (LDP) for pancreatic cancer.

Pretransplant Renal Dysfunction Negatively Affects Prognosis After Living Donor Liver Transplantation: A Single-Center Retrospective Study.

Background: To evaluate the influence of preoperative renal function on prognosis after living donor liver transplantation (LDLT).

Methods: Living donor liver transplantation cases were categorized into 3 groups as follows: renal failure with hemodialysis (HD; n = 42), renal dysfunction (RD; n = 94) (glomerular filtration rate <60 mL/min/1.73 m), and normal renal function (NF; n = 421).

Brg1 controls stemness and metastasis of pancreatic cancer through regulating hypoxia pathway.

Pancreatic ductal adenocarcinoma (PDAC) is a devastating disease. We previously reported that chromatin remodeler Brg1 is essential for acinar cell-derived PDAC formation in mice. However, the functional role of Brg1 in established PDAC and its metastasis remains unknown.

Is frequent measurement of tumor markers beneficial for postoperative surveillance of colorectal cancer?

Purpose: To determine whether frequent measurement of tumor markers triggers early detection of colorectal cancer recurrence.

Methods: Of 1,651 consecutive patients undergoing colorectal cancer surgery between 2010 and 2016, 1,050 were included. CEA and CA 19-9 were considered to be postoperative tumor markers and were measured every 3 months for 3 years, and then every 6 months for 2 years.

Restrictions on monetary payments for human biological substances in Japan: The principle and its ethical implications for stem cell research.

Introduction: Restrictions on financial gains from the sale of human body parts is a leading policy issue surrounding the use of human tissues and cells. However, discrepancies exist between regulations and reality. In stem cell research, in which diverse sources of tissues and cells can be used, unclear regulations can impede research.
