The mechanical properties of halide perovskites have been attracting ever-increasing interest for their significant importance in future industrial applications. However, studies focused on the effect of B-site substitution of molecular perovskites on their mechanical properties are rare, which makes it favorable to shed light on their fundamental structure-mechanical property relationships. Here, using isostructural halide perovskites, [CHN][BCl]·HO (B = NH; K), constructed by ionic bonds and hydrogen bonds, respectively, as the model systems, we investigate their mechanical properties through high-pressure synchrotron X-ray diffraction experiments and density functional theory calculations.

Article Synopsis
  • Spastic pelvic floor syndrome (SPFS) causes abnormal muscle contractions during defecation, leading to issues like constipation and anal blockage, which often requires manual assistance for bowel movements.
  • The study aimed to examine the impacts of botulinum toxin A injections combined with biofeedback on anorectal pressure in patients with pelvic floor muscle spasm syndrome.
  • Results showed a significant decrease in muscle tension and blood pressure after treatment, suggesting this approach is effective, but further research, including randomized controlled trials, is needed to confirm these findings.

  • Lumbar disc herniation (LDH) is a common health issue causing leg or back pain, prompting a clinical trial to assess the effectiveness of Yaobitong capsules (YBT) compared to Jingyaokang capsules (JYK).
  • The trial involved 479 patients who received either YBT or JYK, with outcomes measured using the Oswestry Disability Index (ODI) and visual analogue scale (VAS) over 30 days.
  • Results indicated that YBT significantly improved ODI and VAS scores compared to JYK at various time points, with both treatments having similar safety profiles, suggesting YBT as a more effective option for LDH.

Interferon-alpha (IFN-α) is widely used in the clinical treatment of patients with chronic hepatitis B and hepatocellular carcinoma (HCC). However, high levels of CXCL8 are associated with resistance to IFN-α therapy and poorer prognosis in advanced cancers. In this study, we investigated whether IFN-α could directly induce the production of CXCL8 in HCC cells and whether CXCL8 could antagonize the antitumor activity of IFN-α.

Background: Inflammatory factors are being recognized as critical modulators of host antitumor immunity in liver cancer. We have previously shown that tumor cell-released LC3B positive extracellular vesicles (LC3B EVs) are responsible for malignant progression by dampening antitumor immunity. However, the relationship between LC3B EVs and inflammatory factors in the regulation of the liver cancer microenvironment remains unclear.

Article Synopsis
  • Circulating extracellular vesicles (EVs), particularly autophagosomes expressing the LC3B marker, are being studied as potential cancer biomarkers, especially in liver cancer cases.
  • Researchers analyzed plasma and ascites samples from liver cancer patients, comparing them to non-malignant liver conditions and healthy controls, using various scientific techniques to isolate and characterize these EVs.
  • The study found that liver cancer patients had significantly higher levels of LC3B EVs, which could effectively differentiate them from non-cancer individuals, and those levels decreased after surgical intervention, indicating their potential role in monitoring disease progression or treatment response.

Unlabelled: The immunologic effects of chemotherapy-induced tumor cell death are not completely understood. Accumulating evidence suggests that phagocytic clearance of apoptotic tumor cells, also known as efferocytosis, is an immunologically silent process, thus maintaining an immunosuppressive tumor microenvironment (TME). Here we report that, in the breast tumor microenvironment, thymosin α-1 (Tα-1) significantly reverses M2 polarization of IL10-producing tumor-associated macrophages (TAM) during efferocytosis induced by apoptotic cells.

Article Synopsis
  • Aberrant expression of PD-L1 and P53 has been linked to cancer, and this study investigates their correlation with prognosis in patients with resected pulmonary lymphoepithelioma-like carcinoma (LELC).
  • The study analyzed data from 67 patients, finding that positive expressions of PD-L1 in tumor cells and P53 were associated with longer disease-free survival, especially in early-stage LELC, but not with overall survival.
  • The research suggests that PD-L1 and P53 could serve as potential therapeutic targets and recommends routine detection of these markers to help predict patient outcomes and responses to adjuvant therapy.
