Neoadjuvant Therapy for Pancreatic Ductal Adenocarcinoma: Where Do We Go?

The incidence of pancreatic ductal adenocarcinoma (PDAC) has been on the rise in recent years; however, its clinical diagnosis and treatment remain challenging. Although surgical resection remains the only chance for long-term patient survival, the likelihood of initial resectability is no higher than 20%. Neoadjuvant therapy (NAT) in PDAC aims to transform the proportion of inoperable PDACs into operable cases and reduce the likelihood of recurrence to improve overall survival.

The Significance of the Ocular Adverse Effect Induced by Systemic Taxane Application.

In recent years, in-depth research on anti-tumor therapy has brought the emergence of new active chemotherapeutic agents and combination regimens. However, as one of them, taxane drugs are widely used in clinical practice, but it should be noted that many side reactions caused by their application bring some difficulties to routine management. Among the side reactions related to taxane anti-tumor therapy, ocular adverse reactions are occasionally reported and are not life-threatening but may seriously affect patients' life quality.

Anion-coordination-driven single-double helix switching and chiroptical molecular switching based on oligoureas.

Synthetic foldamers with helical conformation are widely seen, but controllable interconversion amongst different geometries (helical structure and sense) is challenging. Here, a family of oligourea (tetra-, penta-, and hexa-) ligands bearing stereocenters at both ends are designed and shown to switch between single and double helices with concomitant inversion of helical senses upon anion coordination. The tetraurea ligand forms a right-handed single helix upon chloride anion (Cl) binding and is converted into a left-handed double helix when phosphate anion (PO ) is coordinated.

Three pyroptosis patterns were determined with distinct TME cell-infiltrating characteristics and prognosis.

A PVA/LiCl/PEO interpenetrating composite electrolyte with a three-dimensional dual-network for all-solid-state flexible aluminum-air batteries.

Aluminum-air batteries are promising electronic power sources because of their low cost and high energy density. However, traditional aluminum-air batteries are greatly restricted from being used in the field of flexible electronics due to the rigid battery structure, and the irreversible corrosion of the anode by the alkaline electrolyte, which greatly reduces the battery life. To address these issues, a three-dimensional dual-network interpenetrating structure PVA/LiCl/PEO composite gel polymer electrolyte (GPE) is proposed.

Organocatalytic cycloaddition-elimination cascade for atroposelective construction of heterobiaryls.

The first chiral phosphoric acid (CPA) catalyzed cycloaddition-elimination cascade reaction of 2-naphthol- and phenol-derived enecarbamates with azonaphthalenes has been established, providing a highly atroposelective route to an array of axially chiral aryl-C3-benzoindoles in excellent yields with excellent enantioselectivities. The success of this strategy derives from the stepwise process involving CPA-catalyzed asymmetric formal [3 + 2] cycloaddition and subsequent central-to-axial chirality conversion by elimination of a carbamate. In addition, the practicality of this reaction had been verified by varieties of transformations towards functionalized atropisomers.

Stress response decay with aging visualized using a dual-channel logic-based fluorescent probe.

Diagnosing aging for preventative intervention generally relies on the tracking of aging biomarkers in the resting state. However, the static marker levels are insufficient to fully evaluate aging, particularly given that the stress response capacity (SRC) decay is currently viewed as a critical feature of aging. Therefore, we have developed a dual-channel fluorescent probe capable of the logic-based visualization of thiophenol (stressor) and HOCl (thiophenol-activated stress response product) , which provides a new strategy from the time dimension to precisely assess the SRC of individuals under stress using the dual-channel fluorescence ratio.
