Pathological complete response following neoadjuvant chemotherapy with PD-1 inhibitor for locally advanced pancreatic cancer: case report.

Background: In recent years, the incidence of pancreatic cancer has shown an obvious increasing trend worldwide and even causes a greater disease burden to the mankind. Due to the lack of effective early surveillance methods, patients are often in the middle to advanced stages of their disease at the time of detection, thus losing the opportunity for surgery. The currently available chemotherapy regimens are yet to be further improved to prolong patient survival.

Ferroelectricity with concomitant Coulomb screening in van der Waals heterostructures.

Interfacial ferroelectricity emerges in non-centrosymmetric heterostructures consisting of non-polar van der Waals (vdW) layers. Ferroelectricity with concomitant Coulomb screening can switch topological currents or superconductivity and simulate synaptic response. So far, it has only been realized in bilayer graphene moiré superlattices, posing stringent requirements to constituent materials and twist angles.

Genetic and clinical spectrum of steroid-resistant nephrotic syndrome with nuclear pore gene mutation.

Background: Steroid-resistant nephrotic syndrome (SRNS) is insensitive to steroid therapy and overwhelmingly progresses to kidney failure (KF), the known pathogenic genes of which include key subunits of the nuclear pore complex (NPC), a less-recognized contributor to glomerular podocyte injury.

Methods: After analyzing their clinical characterizations and obtaining parental consent, whole-exome sequencing (WES) was performed on patients with SRNS. Several nucleoporin (NUP) biallelic pathogenic variants were identified and further analyzed by cDNA-PCR sequencing from white cells of peripheral blood, minigene assay, immunohistochemical (IHC) staining, and electron microscopy (EM) ultrastructure observation of kidney biopsy, as well as multiple in silico prediction tools, including 3D protein modeling.

α-Actinin-1 deficiency in megakaryocytes causes low platelet count, platelet dysfunction, and mitochondrial impairment.

Cytoskeletal remodeling and mitochondrial bioenergetics play important roles in thrombocytopoiesis and platelet function. Recently, α-actinin-1 mutations have been reported in patients with congenital macrothrombocytopenia. However, the role and underlying mechanism of α-actinin-1 in thrombocytopoiesis and platelet function remain elusive.

The Association between Serum Polychlorinated Biphenyls and Incident Cardiovascular Disease among Type 2 Diabetes.

Background: Polychlorinated biphenyls (PCBs) were associated with cardiovascular disease (CVD) in the general population. However, it is unclear whether PCBs exposure increases the additional risk of CVD among type 2 diabetes (T2D) cases. This study aims to investigate the associations between serum concentrations of PCBs and incident CVD among T2D cases.

Employing chemical proteomics, a comprehensive analysis of the protein targets of the natural coumarin fraxetin has been conducted.

SMARCA4 Deficiency in Lung Cancer: From Signaling Pathway to Potential Therapeutic Targets.

SMARCA4-deficient lung cancer, including thoracic SMARCA4-deficient undifferentiated tumors and SMARCA4-deficient nonsmall-cell lung carcinomas, is a rare and aggressive disease characterized by rapid progression and poor prognosis. This cancer was identified as a distinct entity with specific morphologic and molecular features in the 2021 WHO Classification of Thoracic Tumors. Molecular alterations in SMARCA4 are specific to this type of lung cancer.

Effect of Sodium-Glucose Transporter 2 Inhibitors on Cardiovascular Outcomes in Type 1 Diabetes Mellitus: A Systematic Review and Meta-Analysis of Randomised Controlled Trials.

Background: Cardiovascular disease is a major cause of increasing morbidity and mortality in type 1 diabetes mellitus (T1DM). Although insulin therapy is the cornerstone of T1DM, its difficult use and narrow therapeutic index make it difficult for patients to reach glycated haemoglobin targets, increasing the risk of cardiovascular events. Therefore, the combination of sodium-glucose transporter 2 inhibitors (SGLT2i) can likely improve or provide more cardiovascular benefits to patients with T1DM.

Long segment ureteral reconstruction has always posed a challenge for surgeons. We report the case of a 49 years male patient with a right ureteral obstruction between the ileal orthotopic bladder and the ureter. The patient underwent a 12cm ureteral reconstruction with the prepuce.

A rare case of CD38-negative abdominal multiple extramedullary plasmacytoma and literature review.

Abdominal multiple extramedullary plasmacytoma (EMP) is a rare disease. CD38-negative relapsed/refractory EMP after treatment with daratumumab has never been reported. In 2020, a patient with jaundice was diagnosed with plasmacytoma in another hospital, which progressed one year after receiving multiline therapy.

FTO Alleviates Hepatic Ischemia-Reperfusion Injury by Regulating Apoptosis and Autophagy.

Despite N-methyladenosine (mA) being closely involved in various pathophysiological processes, its potential role in liver injury is largely unknown. We designed the current research to study the potential role of fat mass and obesity-associated protein (FTO), an mA demethylase, on hepatic ischemia-reperfusion injury (IRI). Wild-type mice injected with an adeno-associated virus carrying fat mass and obesity-associated protein (AAV-FTO) or adeno-associated virus carrying green fluorescent protein (GFP) (AAV-GFP) were subjected to a hepatic IRI model in vivo.

A novel balloon-type photoacoustic cell (BTPAC) is proposed to facilitate the detection limitations of acetylene (CH) gas achieving ppb level. Here, an ellipsoidal photoacoustic cavity is employed as the platform for gas-light interaction. By strategically directing the excitation source towards the focal point of the ellipsoidal cavity, ensuring its trajectory traverses the focal point upon each reflection from the interior walls.

After years of research and development, flexible sensors are gradually evolving from the traditional "electronic" paradigm to the "ionic" dimension. Smart flexible sensors derived from the concept of ion transport are gradually emerging in the flexible electronics. In particular, ionic hydrogels have increasingly become the focus of research on flexible sensors as a result of their tunable conductivity, flexibility, biocompatibility, and self-healable capabilities.

Nonacademic predictors of China medical licensing examination.

Background: National Medical Licensing Examination (NMLE) is the entrance exam for medical practice in China, and its general medical knowledge test (GMKT) evaluates abilities of medical students to comprehensively apply medical knowledge to clinical practice. This study aimed to identify nonacademic predictors of GMKT performance, which would benefit medical schools in designing appropriate strategies and techniques to facilitate the transition from medical students to qualified medical practitioners.

Methods: In 1202 medical students, we conducted the deletion-substitution-addition (DSA) and structural equation model (SEM) analyses to identify nonacademic predictors of GMKT performance from 98 candidate variables including early life events, physical conditions, psychological and personality assessments, cognitive abilities, and socioeconomic conditions.

The mediating role of maternal fasting plasma glucose level and lipid levels in the third trimester of pregnancy between pre-pregnancy BMI and offspring physical development at birth.

Unlabelled: While previous research has established correlations between pre-pregnancy body mass index (BMI), late-pregnancy blood glucose, and late-pregnancy blood lipid levels during pregnancy and offspring's physical development, the underlying mechanism of their interaction remains elusive. A birth cohort study was conducted on pregnant women, who are biologically female, delivering at a tertiary hospital in Wuhan City between May 2023 and April 2024, encompassing 1620 participants. We collected maternal socio-demographic data through questionnaires and obtained information on fasting blood glucose (FPG), lipid levels during the third trimester, and neonatal physical development from medical records.

FBXO22 promotes HCC angiogenesis and metastasis via RPS5/AKT/HIF-1α/VEGF-A signaling axis.

The gene F-box only protein 22 (FBXO22) has been discovered to promote the development of liver cancer tumors. Nevertheless, there remains considerable ambiguity regarding the involvement of FBXO22 in the processes of angiogenesis and metastasis in hepatocellular carcinoma (HCC). Our study has confirmed a significant upregulation of FBXO22 expression in both HCC samples and cellular models.
