The control of the sequential self-assembly processes of highly entangled (AgL) (n=2,4,6,8) and AgL coordination polyhedra using side-chain effects was studied via the introduction of linear or branched side chains into the tripodal ligands. In addition to changes in the intermediate polyhedral species affording the multi- pathway process, disruption of the kinetic control of the sequential self-assembly was observed, thus demonstrating the utility of steric control for the construction of 3D-entangled molecular materials on the 5 nm scale with high molecular complexity.

Entangled (M L ) polyhedral complexes represent a unique class of supramolecular architectures that are stabilized by relatively weak metal-acetylene interactions in cooperation with conventional metal-pyridyl coordination. Counter-anion exchange of these complexes with a nitrate (NO ) ion triggered formal metal insertion between the metal centers, and a heteroleptic ternary coordination mode with acetylenic, pyridyl, and nitrate donors was generated on the metal centers. As a result, the main frameworks of the polyhedral complexes M L and M L were formally extended into a new series of concave polyhedra having the compositions M L and M L , respectively.

A 31-year-old man presented to our hospital's Emergency Department with sudden epigastric pain and vomiting. He had undergone endoscopic resection via the retroperitoneal route for a retroperitoneal tumor located in the left diaphragmatic crus of the esophageal hiatus at another hospital 8 months previously. Radiography and computed tomography showed inversion of the stomach beyond the diaphragm into the thoracic cavity, with the gastroesophageal junction serving as the fulcrum point.

Superb control over the helical chirality of discrete (ML) polyhedra ( = 2,4,8, M = Cu or Ag) created from the self-assembly of propeller-shaped ligands (L) equipped with chiral side chains is demonstrated here. Almost perfect chiral induction (>99 : 1) of the helical orientation of the framework was achieved for the largest (ML) cube with 48 small chiral side chains (diameter: ∼5 nm), while no or moderate chiral induction was observed for smaller polyhedra ( = 2, 4). Thus, amplification of the weak chiral inductions of each ligand unit is an efficient way to control the chirality of large discrete nanostructures with high structural complexity.

Overlap syndrome refers to a group of conditions that have clinical features of more than one well-characterised rheumatic disease and meet the respective classification criteria. There are no typical renal histological findings in overlap syndrome. When patients with overlap syndrome develop renal dysfunction, various potential causes, including lupus nephritis (LN), renal crisis by systemic sclerosis, interstitial nephritis, and so on, need to be distinguished.

Epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI) had clinical success in the treatment of non-small cell lung carcinoma (NSCLC). An effect of this drug on kidney has not been clarified and the occurrence of glomerulonephritis related to EGFR-TKI has rarely been reported. We present the case of a 71-year-old man with NSCLC who developed proteinuria and microscopic hematuria with the rise in a titer of MPO-ANCA, when 2 years and 3 months passed since the initiation of erlotinib, one of oral EGFR-TKI.

The cooperation of weak acetylene π-coordination and relatively strong metal-heteroatom coordination has emerged as a promising strategy for the construction of highly complex but well-ordered nanostructures. Here, we report the formation of an (ML) truncated cube (M = Ag) via the oligomerization of an ML subunit stabilized by the secondary π-coordination of an acetylene spacer. This large framework cannot be obtained directly from its components (M and L) but is instead formed by counteranion exchange (BF to NO) of the presynthesized smallest oligomer, the dimeric (ML) cage.

Histiocytic sarcoma is a relatively new disease category and the gastrointestinal origin is sporadic. We report a case of a 74-year-old woman who underwent chemotherapy and proximal gastrectomy for extremely rare, advanced gastric histiocytic sarcoma. The resected specimen was subjected to numerous immunostainings to meet the diagnostic criteria of histiocytic sarcoma and was positive for the histiocyte markers' cluster of differentiation 68 and lysozyme.

Discrete (ML) cages assembled from a tripodal ligand (L) and metal ions (M: Cu(i) or Ag(i)) are embedded in networked coordination hosts formed by partial dissociation of the same discrete cages during the crystallization process. The resulting "eggs-in-an-egg-carton" structures provide unique examples of the co-crystallization of discrete and infinite coordination frameworks.

The self-assembly of nanostructures is dominated by a limited number of strong coordination elements. Herein, we show that metal-acetylene π-coordination of a tripodal ligand (L) with acetylene spacers gave an M L double-propeller motif (M=Cu or Ag ), which dimerized into an M L interlocked cage (M=Cu ). Higher (M L ) oligomers were also selectively obtained: an M L truncated tetrahedron (M=Cu ) and an M L truncated trigonal prism (M=Ag ), both of which contain the same double-propeller motif.

Background: Pancreatic acinar cell carcinoma (PACC), a rare variant of pancreatic malignancy, is generally managed the same way as pancreatic ductal adenocarcinoma (PDAC). Surgical resection is the gateway to curing it; however, once it metastasizes (usually to the liver, lungs, lymph nodes, or peritoneal cavity), systemic chemotherapy has been the only option, but with unfavorable results.

Case Presentation: A 67-year-old man with symptoms of loss of appetite and weight underwent surgery for malignancy of the pancreatic tail extending into the entire pancreas.

Article Synopsis
  • - The study investigates the impact of lymphatic vessel invasion (LVI) and blood vessel invasion (BVI) on the recurrence of endometrial cancer in patients who had surgery with curative intent from 2007 to 2015.
  • - The findings suggest BVI is a stronger independent prognostic factor for recurrence-free survival compared to LVI, with BVI linked to a higher likelihood of hematogenous metastases.
  • - Overall, the results indicate that blood vessel invasion significantly correlates with worse outcomes in endometrial cancer recurrence, highlighting its importance in patient prognosis.

Metallic nanostructures are able to interact with an incident electromagnetic field at subwavelength scales by plasmon resonance which involves the collective oscillation of conduction electrons localized at their surfaces. Among several possible applications of this phenomenon, the theoretical prediction is that optical circuits connecting multiple plasmonic elements will surpass classical electronic circuits at nanoscale because of their much faster light-based information processing. However, the placement and coupling of metallic elements smaller than optical wavelengths currently remain a formidable challenge by top-down manipulations.

We have synthesized a series of triarylamine-cored molecules equipped with an adjacent amide moiety and dendritic peripheral tails in a variety of modes. We show by (1) H NMR and UV/Vis spectroscopy that their supramolecular self-assembly can be promoted in solution upon light stimulation and radical initiation. In addition, we have probed their molecular arrangements and mesomorphic properties in the bulk by integrated studies on their film state by using differential scanning calorimetry (DSC), variable-temperature polarizing optical microscopy (VT-POM), variable-temperature X-ray diffraction (VT-XRD), and atomic force microscopy (AFM).

Efficient end-capping synthesis of neutral donor-acceptor (D-A) [2]rotaxanes without loading any catalysts or activating agents was achieved by utilizing high reactivity of a pentacoordinated hydrosilane toward salicylic acid derivatives. As components of [2]rotaxanes, an electron-deficient naphthalenediimide-containing axle with a salicylic acid terminus and several electron-rich bis(naphthocrown) ether macrocycles were employed. End-capping reactions with the pentacoordinated hydrosilane underwent smoothly even at low temperature to afford the corresponding [2]rotaxanes in good yields.
