High-dimensional photon states (qudits) are pivotal to enhance the information capacity, noise robustness, and data rates of quantum communications. Time-bin entangled qudits are promising candidates for implementing high-dimensional quantum communications over optical fiber networks with processing rates approaching those of classical telecommunications. However, their use is hindered by phase instability, timing inaccuracy, and low scalability of interferometric schemes needed for time-bin processing.

Article Synopsis
  • Follicular tracking is usually done with ultrasound, but it has limited resolution; a new high-resolution imaging technique using near-infrared II (NIR-II) luminescence imaging has been developed for better visualization of ovarian follicles.
  • This approach utilizes an FDA-approved contrast agent, indocyanine green (ICG) conjugated with hCG, allowing targeted monitoring of early follicles and avoiding damage from other imaging methods like CT scans.
  • Results indicate that the NIR-II imaging can accurately identify follicles as small as 50 µm and also effectively detect ovarian tumors and micro-metastatic lesions, presenting a promising tool for infertility assessment and surgical guidance.

The rapid and selective identification of microorganisms is of great significance for clinical therapy applications. To develop high performance probes for microbe determination, we systemically constructed series aggregation-induced emission (AIE) luminogens by modulating the structural planarity, the basicity of functional group, the length of linker moiety and the hydrophobicity based on our previous work. The detail structure-property relationship study based on experimental and theoretical observation revealed that: i) the planar skeleton is essential for probe insertion towards the cell wall via van n der Waals' force.

Bright deep red/near-infrared red (DR/NIR) active type I photosensitizers (PSs) with generating superoxide anion and hydroxyl radical have been regarded as powerful functional materials to fight the "Achilles's heel" of hypoxia from solid tumor. But some problems have still existed, for example, lacking effective molecular designed strategy or typical building block to design precisely type I PSs. In addition, the relationship between fluorescent quantum efficiency and NIR fluorescent color is inconsistent according to energy gap rule.

Purpose: Leiomyosarcoma (LMS) is an aggressive mesenchymal malignant tumor with poor therapeutic options, but the molecular mechanisms underlying LMS remain largely unknown. Increasing evidence indicates that transient receptor potential vanilloid 4 (TRPV4) levels are closely related to the advancement of various malignant tumors through diverse molecular mechanisms. However, the roles and regulatory mechanisms of TRPV4 in LMS progression remain unclear.

Purpose: Self-perceived burden can take a toll on the physical and psychological well-being of cancer couples and prevent them from achieving favorable outcomes. There is limited qualitative research synthesizing the cognition and coping with self-perceived burden among Chinese colorectal cancer patients and their caregivers. Therefore, this study examined perceptions of self-perceived burden and coping strategies from the perspectives of colorectal cancer patients, their spousal caregivers and nursing staff.

The cannabinoid 1 receptor (CB1) is highly expressed in the central nervous system, where its physiological functions include the regulation of energy balance, pain, and addiction. Herein, we develop and validate a technique to use magnetic resonance imaging (MRI) to investigate the distribution of CB1 across mouse brains with high spatial resolution, expanding previously described in vitro studies and in vivo studies with positron emission tomography (PET). To support the MRI investigations, we developed a ligand that is specific for in vivo neuroimaging of CB1.

Myocardial dysfunction is a major cause of early mortality after successful cardiopulmonary resuscitation (CPR) following cardiac arrest (CA). Following the return of spontaneous circulation, myocardial ischemia-reperfusion injury can activate the NF-κB pathway, leading to the transcription of inflammatory genes that impair myocardial function. While clinical studies show hydrocortisone (HC) improves outcomes in CA patients during CPR, its specific role in modulating the NF-κB pathway is unclear.

Colloidal InP/ZnSeS-based quantum dots (QDs) are considered promising building blocks for light-emitting devices due to their environmental friendliness, high quantum yield (QY), and narrow emission. However, the intrinsic type-I band structure severely hinders potential photoelectrochemical (PEC) applications requiring efficient photoexcited carrier separation and transfer. In this study, the optoelectronic properties of InP/ZnSeS QDs are tailored by introducing Al dopants in the ZnSeS layer, which concurrently passivate the surface defects and act as shallow donor states for suppressed non-radiative recombination and improved charge extraction efficiency.

Direct current (DC) motors are crucial in drones, robotics, and electrical devices. Conventionally, the DC motor is driven by a switching electricity converter, which utilizes electrical energy to drive mechanical motion. However, the rapid on-off switching actions in the switching electricity converter would cause electromagnetic interference (EMI), impairing the functionality of drive systems.

The methods available for treating metastatic Ewing sarcoma (ES) are inadequate; thus, innovative therapeutic approaches need to be developed. However, the lack of clinically relevant ES models has hindered the discovery of drugs for this disease. In this study, we established and characterized a patient-derived xenograft (PDX) cell line model, which was constructed using tumor tissue from a patient with metastatic extraskeletal ES.

Colloidal quantum dots (QDs) are emerging as potential candidates for constructing near-infrared (NIR) photodetectors (PDs) and artificial optoelectronic synapses due to solution processability and a tunable bandgap. However, most of the current NIR QDs-optoelectronic devices are still fabricated using QDs with incorporated harmful heavy metals of lead (Pb) and mercury (Hg), showing potential health and environment risks. In this work, we tailored eco-friendly reverse type-I ZnSe/InP QDs by copper (Cu) doping and extended the photoresponse from the visible to NIR region.

Shape symmetry breaking in the formation of inorganic nanostructures is of significant current interest. It was typically achieved through the growth of colloidal nanoparticles with adsorbed chiral molecules. Photochemical processes induced through asymmetric plasmon excitation by circularly polarized light in surface immobilized nanostructures also led to symmetry breaking.

Hydrogels are widely used due to their exceptional biocompatibility and adaptability, but their weak mechanical properties limit their application in biomedical engineering. Herein, we rapidly attained a comprehensive enhancement of silk fibroin hydrogels in mechanical properties by employing a physical-chemical double crosslinking strategy. The SF was ultrasonicated and simultaneously photo-crosslinked to form a di-tyrosine network interspersed with β-sheet blocks, resulting in a SF hydrogel network structure with both rigid and flexible domains.

Traditional trajectory compression algorithms, such as the siliding window (SW) algorithm and the Douglas-Peucker (DP) algorithm, typically use static thresholds based on fixed parameters like ship dimensions or predetermined distances, which limits their adaptive capabilities. In this paper, the adaptive core threshold difference-DP (ACTD-DP) algorithm is proposed based on traditional DP algorithm. Firstly, according to the course value of automatic identification system (AIS) data, the original trajectory data is preprocessed and some redundant points are discarded.

  • Pernicious anemia (PA) is a rare form of anemia caused by vitamin B12 deficiency, which is thought to be more common in Western countries than in places like China.
  • Researchers studied 90 patients in China and found that about 84% of them were diagnosed with PA, suggesting it's more common there than previously believed.
  • It’s important for patients with vitamin B12 deficiency to get regular tests and continue treatment to prevent their condition from getting worse.
