Abstract
Reported herein is a Paternò-Büchi reaction of aromatic double bonds with quinones under visible light irradiation. The reactions of aromatics with quinones exposed to blue LED irradiation yielded oxetanes at -78 °C, which was attributed to both the activation of double bonds in aromatics and the stabilization of oxetanes by thiadiazole, oxadiazole, or selenadiazole groups. The addition of Cu(OTf)2 to the reaction system at room temperature resulted in the formation of diaryl ethers via the copper-catalyzed ring opening of oxetanes in situ. Notably, the substrate scope was extended to general aromatics.

Abstract
The hitherto unknown hexakis(halomethyl)-functionalized tribenzotriquinacenes (TBTQs) 9 and 10 were synthesized from the key 4b,8b,12b-tribromo-TBTQ derivative 6 by an improved route in 67% overall yield. Extension of the bowl-shaped framework of 9 or 10 by threefold condensation with propargylamine or 2-azidoethylamine afforded the corresponding TBTQ-trialkyne 11 and TBTQ-triazide 12, respectively. While attempts to construct bis-TBTQ cages, including homodimerization of 11 and heterocoupling of 11 with 12, were unsuccessful, triazide 12 was found to undergo threefold [3 + 2]-cycloaddition with 3-ethynylaniline and phloroglucinol tripropargyl ether under click chemistry conditions. The latter reaction enabled facile capping of the TBTQ bowl to give the novel cage compound 5 in 22% yield.

Abstract
Abstract
BACKGROUND
IDH-mutant glioblastoma is classified by the 2016 CNS WHO as a group with good prognosis. However, the actual number of cases examined in the literature is relatively small. We hypothesize that IDH-mutant glioblastoma is not a uniform group and should be further stratified.
MATERIAL AND METHODS
We conducted methylation profiles and estimated copy number variations in 64 IDH-mutant glioblastomas.
RESULTS
Our results showed that 10.9%, 53.1%, and 35.9% of tumors belonged to Codel, G-CIMPhigh, and G-CIMP-low methylation subgroups, respectively. G-CIMP-low subgroup was associated with significantly worse OS as compared to G-CIMP-high (P=0.005) and Codel groups (P=0.009). CDKN2A deletion (37.5%) was the most common gene copy number variation, and was associated with G-CIMP-low subgroup (P=0.001). Other frequent copy number changes included MET (4.7%), CCND2 (17.2%), PDGFRA (14.1%), CDK4 (12.5%), and EGFR (12.5%) amplification. Both CDKN2A deletion (P=0.008) and MET amplification (P<0.001) were associated with poor OS in IDH-mutant glioblastomas. Combined epigenetic signatures and gene copy number variations separated IDH-mutant glioblastomas into Group 1 (Codel), Group 2 (GCIMP- high), Group 3 (G-CIMP-low without CDKN2A and MET alterations), and Group 4 (G-CIMP-low with CDKN2A/MET alteration). Survival analysis revealed Group 1 had a favorable OS (median survival: 41.3 months), while Groups 2 and 3 exhibited an intermediate OS (median survival: 20.6 and 21.8 months, respectively). Group 4 exhibited the worst OS (median survival: 8.4 months). Multivariable analysis confirmed the independent prognostic significance of our Groups.
CONCLUSION
IDH-mutant glioblastomas should be stratified for risk with combined epigenetic signature and CDKN2A/MET status and some cases have poor outcome.

Abstract
Abstract
BACKGROUND
Germinoma is the commonest CNS germ cell tumor. An important histological feature is prominent immune cell infiltrates. The composition of such immune cell infiltrates remains under-investigated in the literature.
MATERIAL AND METHODS
We collected a cohort of 40 cases of intra-cranial germinomas and examined the clinical and histopathological features. The tumor infiltrating immune cells were characterized by immunohistochemistry and image analysis.
RESULTS
Across the cohort, the mean positivity ± SE of CD3-positive T cell and CD20-positive B cells was 31.2% ± 3.1% and 15.2% ± 2.2%, respectively (p<0.001). The mean positivity of CD4-positive T helper cell and CD8-positive cytotoxic T cell was 19% ± 2.3% and 14.3% ± 1.7%, respectively (p<0.001). PD-L1 expression was detected in 50% of the cases and was observed exclusively in immune cells but not in neoplastic cells. Germinomas with positive PD-L1 expression had significantly more abundant CD3-positive T cells (p=0.001), CD4-positive T helper cells (p<0.001) and CD8-positive cytotoxic T cells (p=0.004) as compared with those lacking PD-L1 expression. Immunostain for HLA-A and HLA-B revealed loss of HLA class I expression occurring in 92.5% of the germinomas. Loss of HLA class I expression was associated with less abundant CD3-positive T cells (p=0.04).
CONCLUSION
Taken together, the predominant T cells infiltrate and PD-L1 expression suggest anti-PD-L1 therapeutic agents as potential novel treatment option for germinoma patients. The loss of HLA class I may represent one of the mechanisms for tumor immune escape in germinoma.

Abstract
In this work, a trifunctional N,O-building block, 5-(4-carboxyphenoxy)nicotinic acid (H2cpna), that combines three distinct types of functional groups (COOH, N-pyridyl, and O-ether) was used for the hydrothermal assembly of thirteen new coordination compounds: [Co(μ3-Hcpna)2]n (1), [Mn(μ4-cpna)(H2O)]n (2), [Mn(μ4-cpna)(H2O)2]n (3), [Mn(μ-cpna)(2,2'-bipy)(H2O)2]n (4), {[Ni(μ3-cpna)(2,2'-bipy)(H2O)]2·H2O}n (5), {[Cd(μ3-cpna)(2,2'-bipy)]·2H2O}n (6), [Zn2(μ-cpna)2(2,2'-bipy)2] (7), [Cu(μ-cpna)(2,2'-bipy)(H2O)]n (8), {[Mn(μ-cpna)(phen)2]·6H2O}n (9), {[Ni(μ3-cpna)(phen)(H2O)]·H2O}n (10), [Zn2(μ-cpna)2(phen)2] (11), {[Pb(μ3-cpna)(phen)]·H2O}n (12), and [Ni(μ3-cpna)(4,4'-bipy)0.5(H2O)]n (13). These products were synthesized from the corresponding metal(ii) chlorides, H2cpna, NaOH, and optional N-donor supporting ligands or templates {bis(4-pyridyl)amine (bpa), 2,2'-bipyridine (2,2'-bipy), 4,4'-bipyridine (4,4'-bipy), or 1,10-phenanthroline (phen)}. Products 1-13 were characterized in the solid state by standard methods, including elemental and thermogravimetric analysis (TGA), IR spectroscopy, and powder (PXRD) and single-crystal X-ray diffraction. The structures of 1-13 feature distinct structural types, namely the 3D metal-organic frameworks (MOFs 1-3), the 2D coordination polymers (5, 6, 10, 12, and 13), the 1D coordination polymers (4, 8, and 9), and the 0D discrete cyclic dimers (7 and 11). Such a wide structural diversity of 1-13 is driven by various factors, including the type of the metal(ii) node, the deprotonation degree of H2cpna, and/or the type of supporting ligand or template. Notably, an addition of bpa can tune the structure of MOF 3 by the template effect. Topological classification of underlying metal-organic networks was performed, leading to several distinct topological nets: rtl (in 1), hxg-d-4-C2/m (in 2), sra (in 3), 2C1 (in 4, 8 and 9), fes (in 5, 10, and 12), hcb (in 6), and 3,4L83 (in 13). The magnetic behavior of 1-5, 8-10, and 13 was studied and theoretically modeled, disclosing antiferromagnetic interactions. The luminescence behavior of 6, 7, 11, and 12 was also investigated.

Abstract
Two molecules containing a central diketopyrrolopyrrole and two oligothiophene units have been designed and synthesized. Comparisons between the molecules containing terminal F (FDPP) and Cl (CDPP) atoms allowed us to evaluate the effects of halogenation on the photovoltaic properties of the small molecule organic solar cells (OSCs). The OSCs devices employing FDPP:PC71BM films showed power conversion efficiencies up to 4.32%, suggesting that fluorination is an efficient method for constructing small molecules for OSCs.

Abstract
Understanding the effects of intermolecular interactions on the charge-transport properties of metal/molecule/metal junctions is an important step towards using individual molecules as building blocks for electronic devices. This work reports a systematic electron-transport investigation on a series of "core-shell"-structured oligo(phenylene ethynylene) (Gn-OPE) molecular wires. By using dendrimers of different generations as insulating "shells", the intermolecular π-π interactions between the OPE "cores" can be precisely controlled in single-component monolayers. Three techniques are used to evaluate the electron-transport properties of the Au/Gn-OPE/Au molecular junctions, including crossed-wire junction, scanning tunneling spectroscopy (STS), and scanning tunneling microscope (STM) break-junction techniques. The STM break-junction measurement reveals that the electron-transport pathways are strongly affected by the size of the side groups. When the side groups are small, electron transport could occur through three pathways, including through single-molecule junctions, double-molecule junctions, and molecular bridges between adjacent molecules formed by aromatic π-π coupling. The dendrimer shells effectively prohibit the π-π coupling effect, but at the same time, very large dendrimer side groups may hinder the formation of Au-S bonds. A first-generation dendrimer acts as an optimal shell that only allows electron transport through the single-molecule junction pathway, and forbids the other undesired pathways. It is demonstrated that the dendrimer-based core-shell strategy allows the single-molecule conductance to be probed in a homogenous monolayer without the influence of intermolecular π-π interactions.

Abstract
In the title compound, C(20)H(14), a naphthalene ring system is linked at the 2-position to the 2-C atom of the five-membered ring of an azulene unit. The compound crystallizes with two reasonably similar mol-ecules in the asymmetric unit. Neither mol-ecule is perfectly planar: the r.m.s. deviations from the best fit planes through all non-H atoms are 0.092 and 0.091 Å for the two mol-ecules. The dihedral angle between the mol-ecular planes is 49.60 (4)°. The naphthalene and azulene ring systems are inclined at dihedral angles of 6.54 (12) and 5.68 (12)° in the two mol-ecules. The crystal structure exhibits two sets of parallel layers, a typical edge-to-face herringbone packing arrangement. The structure is stabilized by an extensive series of weak C-H⋯π inter-actions.

Abstract
Two series of oligo(phenylene ethynylene)s (OPEs) with different dendrimer side groups have been designed and synthesized. The molecules contain thiol groups at both ends to enable interconnection between nanoscale gapped metallic electrodes. The different dendrimer groups act as "shells", allowing tailoring to the nanoscopic environment surrounding the OPE "core". Meanwhile, the dendrimer shells also act as spacers for the precise control of the packing density and intermolecular interaction between the OPE cores. [structure: see text].

Abstract
Twenty-four-hour urine iodine and afternoon casual urine iodine were determined in children aged 7-14 years grouped into A, B, C, and D at two-year interval in the areas where iodized salt prophylaxis had been instituted. Results showed there was no significant difference between urine iodine values expressed in median of microgram/g Cr x creatinine coefficient and in microgram/24 hr, and the former was considered to reflect the real iodine value in urine. Urine iodine in children of groups C and D (older) was greater than of A and B (younger). Urine iodine reached the lower limit only in 51.2% of the children aged 13-14 years in Heba Township where iodized salt prophylaxis was instituted, with 75 micrograms iodine intake daily as lower limit. It suggested iodine deficiency remained a problem in that area.

Abstract
Reaction of serum growth hormone in cretins whose pituitary and thyroid function have returned to normal in IDD-control by using iodized salt to arginine and clonidine in continuous excitement tests ws observed. The result is that during the phase of clonidine excitement, serum growth hormone in cretins was obviously lower than that in normal controls and the reaction peak value, maximum increase value and reaction time all markedly lower than those of the normal controls. 3 cases (18.8%) had no excitement reaction during the phase of arginine excitement, 8 cases (50.0%) no reaction during the phase of clonidine excitement and 2 cases (12.5%) no reaction in the entire process of continuous tests. The results indicate that patients with cretinism suffer from low reserve function of pituitary growth hormone and insufficiency of synthesis even after ther thyroid function has returned to normal.
