Acid-triggered size reduction of nanomedicines for enhancing tumor therapy efficacy.

Nanomedicines whose size can be varied on demand may synchronously achieve excellent tumor accumulation and penetration. In this study, by taking advantage of the pH sensitivity of a boronate ester, we synthesized acid-triggered size-reducing polymer nanoparticles (named PCD) by cross-linking β-cyclodextrin-cored multiarm polymers through the boronate ester. In PCD, the antitumor agent doxorubicin was loaded the pH-sensitive hydrazone linkage.

Full-view volumetric photoacoustic imaging using a hemispheric transducer array combined with an acoustic reflector.

Photoacoustic computed tomography (PACT) has evoked extensive interest for applications in preclinical and clinical research. However, the current systems suffer from the limited view provided by detection setups, thus impeding the sufficient acquisition of intricate tissue structures. Here, we propose an approach to enable fast 3D full-view imaging.

Standardly Trained Peer Volunteer-Led, Social App Recruiting-Based Human Immunodeficiency Virus Testing Strategy Using Rapid Testing Kits (SPARK) Among Men Who Have Sex With Men: A Population-Based Survey Evaluation.

Methods: Between March 2020 and December 2021, 177 trained peer volunteers tested 7256 eligible MSM testers.

Arithmetic fundamental lemma for the spherical Hecke algebra.

We define Hecke correspondences and Hecke operators on unitary RZ spaces and study their basic geometric properties, including a commutativity conjecture on Hecke operators. Then we formulate the arithmetic fundamental lemma conjecture for the spherical Hecke algebra. We also formulate a conjecture on the abundance of spherical Hecke functions with identically vanishing first derivative of orbital integrals.

Incidence and risk factors for unplanned readmission after total hip arthroplasty for osteonecrosis of the femoral head.

Objective: To investigate the incidence, primary causes, and risk factors for unplanned readmissions within one year after the first primary total hip arthroplasty (THA) for osteonecrosis of the femoral head (ONFH).

Methods: Data were retrospectively collected from patients who had undergone the first primary THA for ONFH at two tertiary hospitals between January 2021 and December 2022, with complete 1-year follow-up assessments. Patients who experienced an unplanned readmission within 1 year were classified as the readmission group, while the others as the non-readmission group.

General anesthesia induces acute cell-free DNA methylation changes in peripheral blood.

Background: Short-term and long-term adverse events could occur after general anesthesia (GA) and the specific mechanism driving these effects has not yet been well-characterized. In this study, we aimed to evaluate the global effect of GA on DNA methylation in the cell-free DNA (cfDNA) of surgical lung-nodule patients.

Methods: This large retrospective cohort study enrolled 1,006 surgical lung nodule patients (529 pre-anesthesia, and 477 post-anesthesia).

Comparison of watershed analysis with indocyanine green fluorescence staining and modified inflation-deflation method in single-port thoracoscopic complex pulmonary segmentectomy.

Background: The increasing utilization of computed tomography (CT) scans has significantly elevated the detection rate of pulmonary nodules. Pulmonary segmentectomy has become the preferred surgical technique for peripheral non-small cell lung cancer (NSCLC) measuring 2 cm or smaller. Various methods for identifying the intersegmental planes (ISPs) are currently employed.

Mesenchymal stem cell treatment alleviates seawater drowning induced lung injury by inhibiting the TNFα/Snail/EMT pathway.

Background: Seawater drowning (SWD) has been an escalating hazard in recent years. It can not only cause immediate death but can also inflict severe complications, such as acute lung injury (ALI), which greatly increases the mortality rate. Thus, investigating the mechanism of SWD induced lung injury and discovering effective treatments is of great importance.

Surgical repair of benign thoracogastric airway fistula after esophagectomy using a pedicled myocutaneous flap.

Thoracogastric airway fistula (TGAF) is a rare but devastating complication that may occur following esophagectomy. The most effective method for repairing the defect between the airway and digestive tract is the interposition of a pedicled soft tissue in situ. However, this approach is associated with a high risk and remains challenging for surgeons.

Single-port robot-assisted thoracoscopic right lower bronchial sleeve lobectomy utilizing the Shurui single-port robotic system.

Sleeve lobectomy has solidified its position as a preferred alternative to pneumonectomy due to its significant advantage in preserving lung function, whereas right lower lobe sleeve lobectomy remains relatively uncommon because of the higher technical challenge. With the development of minimally invasive technology and experience acquired over the years, robot-assisted thoracoscopic surgery (RATS) has shown progress and distinct advantages compared to the traditional thoracotomy and video-assisted thoracoscopic surgery (VATS) approach. Owing to its 3D vision, bendable wrist joints, and tremor filtration capabilities, this surgical technique exhibits great advantages in complex thoracic operations demanding for reconstructive procedures compared to traditional thoracoscopic surgery.

Local excision for middle-low rectal cancer after neoadjuvant chemoradiation: A retrospective study from a single tertiary center.

Background: Rectal cancer has become one of the leading malignancies threatening people's health. For locally advanced rectal cancer (LARC), the comprehensive strategy combining neoadjuvant chemoradiotherapy (NCRT), total mesorectal excision (TME), and adjuvant chemotherapy has emerged as a standard treatment regimen, leading to favorable local control and long-term survival. However, in recent years, an increasing attention has been paid on the exploration of organ preservation strategies, aiming to enhance quality of life while maintaining optimal oncological treatment outcomes.

Case report: A case of giant malignant solitary fibrous tumor of the pleura with Doege-Potter's syndrome and review of the literature.

The solitary fibrous tumor of the pleura (SFTP) is a rare intrathoracic neoplasm that commonly originates from the subpleural mesenchymal cells of the visceral pleura and accounts for less than 5% of all pleural tumors. We reported a case of a 54-year-old man with a two-week history of hypoglycemia, a six-month history of productive cough and fatigue, and chronic right chest pain. Radiological techniques revealed a giant intra-thoracic mass with hypervascularization, and pathological staining was carried out to make a definitive diagnosis of SFTP.

Causal relationship between cathepsins and major salivary gland neoplasms: a bidirectional Mendelian randomization study.

Background: Observational studies have suggested a potential link between cathepsins and major salivary gland neoplasms (MSGNs), but the causality of this relationship remains uncertain. Mendelian randomization (MR) is a significant genetic method that employs single nucleotide polymorphisms (SNPs) as instrumental variables (IVs). This approach reduces confounding effects, enabling the analysis of causal relationships between exposure traits and outcome diseases.

The objective of this study was to examine the association through a cohort study of the American population.

Bidirectional high-speed optical wireless communication with tunable large field of view assisted by liquid crystal metadevice.

Beam-steered infrared (IR) light communication has gained tremendous attention as one of the solutions of congested wireless communication traffic. High performance active beam-steering devices play a crucial role in data allocation and exchange. Conventional beam-steering devices such as spatial light modulator (SLM) and micro-electrical mechanical system (MEMS) mirror and the current emerging nonmechanical beam-steering metasurface-based devices are challenging to realize a large tunable steering angle beyond several degrees, which significantly hinders the spatial application of optical wireless communications (OWC).

Structure of the SMYD2-PARP1 Complex Reveals Both Productive and Allosteric Modes of Peptide Binding.

Allosteric regulation allows proteins to dynamically respond to environmental cues by modulating activity at sites away from the catalytic center. Despite its importance, the SET-domain protein lysine methyltransferase superfamily has been understudied. Here, we present four crystal structures of SMYD2, a unique family member with a MYND domain.
