Background: Ovarian cancer exhibits striking metastatic tropism for the omentum, where lipid-laden macrophages are key mediators that fuel disease progression. However, the mechanisms governing their formation and pro-metastatic functions remain poorly understood. As extracellular vesicles (EVs) have as critical regulators of tumor-stroma crosstalk in metastatic niches, we sought to define how ovarian cancer-derived EVs orchestrate macrophages and adipocytes, and their impact on omental metastasis, aiming to explore potential therapeutic interventions.

Constructing micro-/nanostructure-modulated photofields in upconversion devices to absorb low-energy photons and emit high-energy light is revolutionary for bioimaging, lasers, and photovoltaics, with proven capability to boost upconversion luminescence (UCL) by orders of magnitude. However, photoenergy dissipation and inadequate absorption result in excitation thresholds exceeding 1 mW/cm, which exceeds retinal safety limits and hinders wearable upconversion optics. Here, we report the use of upconversion core-shell microsphere-induced infrared field convergence, NaYF:Yb,Er shell-based resonant cavities for multiple reflection-absorption-upconversion and photonic crystal amplifiers to improve UCL intensity three orders of magnitude, and achieve ultralow threshold (0.

Article Synopsis
  • Bone or brain metastases occur in 20-40% of late-stage non-small-cell lung cancer (NSCLC) patients, leading to a poor median survival of 4-6 months, yet the distinctions in metastatic types at the single-cell level remain underexplored.
  • A comprehensive analysis of 14 biopsy samples from treatment-naïve advanced NSCLC patients revealed significant differences in cancer-associated fibroblast (CAF) populations among the bone, brain, and intrapulmonary metastases.
  • The study highlights the role of specific CAF subpopulations in promoting either bone or brain metastasis and suggests potential therapeutic targets by disrupting their interactions with tumor cells to inhibit metastasis.

A case of a patient with a true large unruptured posterior communicating artery (PCoA) aneurysm in a distal segment of PCoA, who was treated by interventional therapy via an ipsilateral occlusion of the internal carotid artery (ICA), is reported. Although the treatment went very well and the patient recovered very well, angiography 6 months after the operation showed that left PCoA had occluded and the aneurysm disappeared. The temporary recanalization of occluded ophthalmic segment of ICA can be a pathway for interventional therapy.

Background: Invasive moles are a subtype of gestational trophoblastic neoplasia (GTN) that usually develops after hydatidiform molar pregnancies. Uterine rupture in high-risk GTN is a rare and potentially catastrophic event. The treatment of invasive mole perforation with uterine rupture is particularly challenging in young women who desire fertility preservation.

Ovarian carcinoma inherently possesses a distinct metastatic organotropism for the adipose-rich omentum, contributing to disease progression. Although the premetastatic microenvironment (PMM) has been known to often play a prometastatic role during the process, incomplete mechanistic insight into PMM formation has prevented its therapeutic targeting. Omental fibroblasts can be activated by tumour cells to differentiate into myofibroblasts, termed the fibroblast-to-myofibroblast transition (FMT), which, in turn, enhances cancer aggressiveness.

Tyrosine kinase with immunoglobulin and epidermal growth factor homology domains 2 (TIE2)-expressing macrophages (TEMs) are an angiogenesis-promoting subset of tumor-associated macrophages that have been demonstrated to be increased in solid tumors and associated with the progression of cervical cancer. However, the induction mechanism of TEMs remains unclear. Here, based on multicolor immunofluorescence of 58 cervical cancer tissues and the GEPIA database, we found that TEMs were increased in TIE2-high cervical cancer and related to shorter survival.

Glacier melting is one of the important causes of glacier morphology change and can provide basic parameters for calculating glacier volume change and glacier mass balance, which, in turn, is important for evaluating water resources. However, it is difficult to obtain large-scale time series of glacier changes due to the cloudy and foggy conditions which are typical of mountain areas. Gravity-measuring satellites and laser altimetry satellites can monitor changes in glacier volume over a wide area, while synthetic-aperture radar satellites can monitoring glacier morphology with a high spatial and temporal resolution.
