Defect engineering is an extremely effective strategy for modifying metal-organic frameworks (MOFs), which can break through the application limitations of traditional MOFs and enhance their functionality. Herein, we report a highly robust nanoporous thulium(III)-organic framework, {[Tm(BDCP)(HO)](NO)·3DMF·2HO} (), with [Tm(COO)(HO)] chains and [Tm(COO)(HO)] dinuclears as metal nodes and 2,6-bis(2,4-dicarboxylphenyl)-4-(4-carboxylphenyl)pyridine (BDCP) linkers. In , each of the four chains of [Tm(COO)] and the two rows of [Tm(COO)(HO)] units is unified by the organic skeleton, resulting in a rectangular nanochannel with dimensions of 15.

In order to achieve the high adsorption and catalytic performance of CO, the direct self-assembly of robust defect-engineered MOFs is a scarcely reported and challenging proposition. Herein, a highly robust nanoporous indium(III)-organic framework of {[In(CPPDA)(HO)](NO)·2DMF·3HO} (NUC-107) consisting of two kinds of inorganic units of chain-shaped [In(COO)(HO)] and watery binuclear [In(COO)(HO)] was generated by regulating the growth environment. It is worth mentioning that [In(COO)(HO)] is very rare in terms of its richer associated water molecules, implying that defect-enriched metal ions in the activated host framework can serve as strong Lewis acid.

Background: Adding immune checkpoint inhibitors (ICIs) to the chemotherapy has shown significant clinical benefits in neoadjuvant treatment of locally advanced esophageal squamous cell carcinoma (ESCC). Sintilimab is one such ICI used for treatment. Herein, we designed a trial to evaluate the safety and efficacy of sintilimab combined with paclitaxel and platinum for locally advanced resectable ESCC.

Orifice reduction strategies for da Vinci robotic surgery have been a hot topic of research in recent years. We retrospectively analyzed the perioperative outcomes of robotic-assisted thoracoscopic surgery (RATS) with two, three, and four-hole approaches in radical lung cancer surgery. Our results revealed that the two-hole group has advantages in terms of operative time, postoperative 3-day drainage, postoperative drainage time, postoperative hospital stay and postoperative day 3 visual analogue scale (VAS) pain scores.

Background: Lung cancer is the leading cause of cancer-related death worldwide, and patients have limited survival benefits from traditional treatments such as surgery, radiotherapy and chemotherapy. As a new treatment for lung cancer, immunotherapy has significantly prolonged the overall survival (OS) of patients. However, only some patients can benefit from it.

Article Synopsis
  • Qingyuan partridge chicken is a notable Chinese yellow broiler, with a focus on five traits analyzed at 105 days old: body weight (BW), comb height (CH), shank length (SL), shank girth (SG), and feather maturity (FM).
  • The study aimed to estimate genetic parameters, specifically direct additive genetic correlations, using about 9600 records and different multi-trait models to enhance breeding strategies.
  • Results showed varying heritability estimates for the traits, with direct heritabilities ranging from 0.14 to 0.53, and genetic correlations indicating some positive and negative associations among the traits, providing insights for selective breeding.

Article Synopsis
  • SYNGR2 is a protein that regulates membrane traffic in non-neuronal cells, and its role in esophageal squamous cell carcinoma (ESCC) was studied by analyzing data from The Cancer Genome Atlas and Gene Expression Omnibus databases.
  • Findings indicate that SYNGR2 is overexpressed in ESCC and is linked to poorer survival outcomes, as well as specific cancer characteristics like T stage.
  • The study suggests that SYNGR2's expression and methylation patterns correlate with immune infiltration and could serve as a potential biomarker for prognosis in ESCC patients.

Background: Lung cancer is the cancer with the highest mortality at home and abroad at present. The detection of lung nodules is a key step to reducing the mortality of lung cancer. Artificial intelligence-assisted diagnosis system presents as the state of the art in the area of nodule detection, differentiation between benign and malignant and diagnosis of invasive subtypes, however, a validation with clinical data is necessary for further application.

Background: The present study sought to investigate the efficiency and safety of slanted bilateral lateral rectus recession for the treatment of convergence insufficiency-type intermittent exotropia.

Methods: This retrospective study included 34 patients who underwent slanted bilateral lateral rectus recession for convergence insufficiency-type intermittent exotropia in Shandong Provincial Hospital affiliated to Shandong First Medical University between September 2013 and October 2015 with a minimum follow-up of 6 months. A successful surgical alignment was defined as + 5 (positive for esotropia) to - 10 (negative for exotropia) prism diopters (PD) of orthotropia in the primary position while viewing distant or near targets and a near-distance deviation difference ≤ 8PD.

Posterior capsule opacification (PCO) remains the most common complication of pediatric cataract surgery despite continuous efforts to reduce its incidence. For this reason, pediatric cataract surgeons have expended considerable effort into preventing and mitigating PCO. The intraocular lens (IOL) optic capture technique has been used for the prevention of PCO after pediatric cataract surgery for more than 20y, but there is still no professional consensus.

Purpose: To assess the level of control in intermittent exotropia by applying the office-based 6-point control scale to far-distance testing.

Methods: Fifty-two children with intermittent exotropia were enrolled in this prospective, noninterventional case series. Control of exodeviation was assessed at indoor distance (ID) of 3 m and near distance of 33 cm using the office-based 6-point control scale, which was additionally applied to indoor far distance (IFD) fixation of 30 m and outdoor far distance (OFD) fixation of 50 m.

Aims: To compare prospectively the surgical outcomes of different surgery procedures for convergence insufficiency (CI)-type intermittent exotropia (IXT) in children.

Methods: Forty-five children with CI-type IXT were included in this prospective surgical study with 6 months follow-up. According to the different surgical procedures, all children were randomly divided into three groups: the unilateral medial rectus resection (UMR) group (15 cases), the bilateral medial rectus resections (BMR) group (14 cases) and the improved unilateral recession-resection (R&R) group (16 cases).

Acanthamoeba keratitis (AK) is a painful, vision-threatening infection caused by pathogenic strains of the protozoan, Acanthamoeba. Toll-like receptors (TLRs), which are important components of innate immunity, have an important role in the detection of foreign pathogens and the signaling cascades in host cells. However, no report on the interaction between Acanthamoeba and TLR has been found.
