The compounds and complexes 1,4-C6H4(C≡C-cyclo-3-C4H3S)2 (2), trans-Pt(C≡C-cyclo-3-C4H3S)2(PEt3)2 (3), trans-Ru(C≡C-cyclo-3-C4H3S)2(dppe)2 (4) and trans-Ru(C≡C-cyclo-3-C4H3S)2{P(OEt)3}4 (5) featuring the 3-thienyl moiety as a surface contacting group for gold electrodes have been prepared, crystallographically characterised in the case of 3 - 5, and studied in metal|molecule|metal junctions using both STM-I(s) and STM-BJ methods. The compounds exhibit similar conductance profiles, with a low conductance feature being more readily identified by STM-I(s) methods, and a higher feature by the STM-BJ method...

Palladium-catalyzed ring-opening reactions of cyclopropanated 7-oxabenzonorbornadiene derivatives using alcohol nucleophiles were investigated. The optimal conditions were found to be 10 mol % PdCl2(CH3CN)2 in methanol, offering yields up to 92%. The reaction was successful using primary, secondary and tertiary alcohol nucleophiles and was compatible with a variety of substituents on cyclopropanated oxabenzonorbornadiene. With unsymmetrical C1-substituted cyclopropanated 7-oxabenzonorbornadienes, the regioselectivity of the reaction was excellent, forming only one regioisomer in all cases...

This case describes difficulty with conjunctival closure in an 80-year-old woman with CREST syndrome, a subset of systemic scleroderma. The patient underwent uneventful glaucoma drainage device implantation, but friability of the conjunctiva was noted during closure. Amniotic membrane was used to ensure secure closure, and the patient had a successful outcome. There is a paucity of existing studies on patients with CREST syndrome and their ocular findings. This report sheds light on ocular findings in this autoimmune disease and the necessity for alternative closure methods in special cases...

Charcot-Marie-Tooth disease comprises a group of disorders characterized by progressive muscle weakness and wasting. Reviewing the anaesthetic literature produced conflicting reports about the best anaesthetic options for patients with CMTD; as they are at increased risk of prolonged response to muscle relaxants, malignant hyperthermia and risks of regional anaesthesia. We present a case of the successful use of total intravenous anaesthesia with dexmedetomidine and propofol combined with caudal block using bupivacaine mixed with dexmedetomidine without any complications, for a 17 year old male patient with Charcot Marie-Tooth disease who underwent a lower limb orthopedic surgery...

The ancillary ligands 4'-(4-pyridyl)-2,2':6',2''-terpyridine and 4'-(2,3-dihydrobenzo[b]thiophene)-2,2'-6',2"-terpyridine were used to synthesize two series of mono- and dinuclear ruthenium complexes differing in their lengths and anchoring groups. The electrochemical and single-molecular conductance properties of these two series of ruthenium complexes were studied experimentally by means of cyclic voltammetry and the scanning tunneling microscopy-break junction technique (STM-BJ) and theoretically by means of density functional theory (DFT)...

Anxiety disorders, including generalized anxiety disorder (GAD), social anxiety disorder (SAD), and panic anxiety disorder (PAD), are a group of common psychiatric conditions. They are characterized by excessive worrying, uneasiness, and fear of future events, such that they affect social and occupational functioning. Anxiety disorders can alter behavior and cognition as well, yet little is known about the particular domains they affect. In this study, we tested the cognitive correlates of medication-free patients with GAD, SAD, and PAD, along with matched healthy participants using a probabilistic category-learning task that allows the dissociation between positive and negative feedback learning...

Plastics containing brominated flame retardants (BFRs) constitute the major fraction of nonmetallic content in e-waste. Co-pyrolysis of BFRs with hematite (Fe2O3) represents a viable option for the thermal recycling of BFRs. Consensus of experimental findings confirms the excellent bromine fixation ability of Fe2O3 and the subsequent formation of iron bromides. This contribution provides a comprehensive mechanistic account of the primary reactions between a cluster model of Fe2O3 and major bromine-bearing products from the decomposition of tetrabromobisphenol A (TBBA), the most commonly deployed BFR...

Colorectal cancer (CRC) is one of the most common human malignant tumors worldwide. Arising from the transformation of epithelial cells in the colon and/or rectum into malignant cells, the foundation of CRC pathogenesis lies in the progressive accumulation of mutations in oncogenes and tumor-suppressor genes, such as KRAS and APC. Resistance to apoptosis is one of the key mechanisms in the development of CRC as it is for any other kind of cancer. Natural products have been shown to induce the expression of apoptosis regulators that are blocked in cancer cells...

OBJECTIVES: The objective of this study was to determine if physicians would alter their prescribing preferences after sampling liquid formulations of medications for common pediatric diagnoses. METHODS: This was a prospective interventional before/after study conducted at an academic medical center in the United States. The participants of interest included emergency, family medicine, and pediatric physicians. Participants initially completed a brief survey for their primary oral liquid medication of choice for the treatment of selected disease states...

PURPOSE: The chemokine (C-X-C Motif) receptor 4 (CXCR4) and its ligand, stromal-cell derived factor-1 (SDF-1), are frequently overexpressed in a variety of solid tumors, and are believed to play important roles in the regulation of organ-specific metastasis, tumor growth, invasion, and survival. In this randomized Phase 2 trial, we evaluated the safety and efficacy of LY2510924 (LY), a peptide antagonist of CXCR4, combined with sunitinib (SUN) in the first-line treatment of advanced renal cell carcinoma (RCC)...

Increased histone deacetylase (HDAC) activity and the resulting dysregulation of protein acetylation is an integral event in retinal degenerations associated with ischemia and ocular hypertension. This study investigates the role of preconditioning on the process of acetylation in ischemic retinal injury. Rat eyes were unilaterally subjected to retinal injury by 45 min of acute ischemia, and retinal neuroprotection induced by 5 min of an ischemic preconditioning (IPC) event. HDAC activity was evaluated by a fluorometric enzymatic assay with selective isoform inhibitors...

The single molecule conductances of a series of bis-2,2':6',2″-terpyridine complexes featuring Ru(II), Fe(II), and Co(II) metal ions and trimethylsilylethynyl (Me3SiC≡C-) or thiomethyl (MeS-) surface contact groups have been determined. In the absence of electrochemical gating, these complexes behave as tunneling barriers, with conductance properties determined more by the strength of the electrode-molecule contact and the structure of the "linker" than the nature of the metal-ion or redox properties of the complex...

BACKGROUND: The search for new cholinesterase inhibitors is still a promising approach for management of Alzheimer`s disease. Schiff bases are considered as important class of organic compounds, which have wide range of applications including as enzyme inhibitors. In the present study, a new green ionic liquid mediated strategy was developed for convenient synthesis of two series of Schiff bases 3(a-j) and 5(a-j) as potential cholinesterase inhibitors using aromatic aldehydes and primary amines in [bmim]Br...

A quantum circuit rule for combining quantum interference effects in the conductive properties of oligo(phenyleneethynylene) (OPE)-type molecules possessing three aromatic rings was investigated both experimentally and theoretically. Molecules were of the type X-Y-X, where X represents pyridyl anchors with para (p), meta (m) or ortho (o) connectivities and Y represents a phenyl ring with p and m connectivities. The conductances GXmX (GXpX) of molecules of the form X-m-X (X-p-X), with meta (para) connections in the central ring, were predominantly lower (higher), irrespective of the meta, para or ortho nature of the anchor groups X, demonstrating that conductance is dominated by the nature of quantum interference in the central ring Y...

Novel aromatic embedded Schiff bases have been synthesized in ionic liquid [bmim]Br and evaluated in vitro for their acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) enzymes inhibitory activities. Among the newly synthesized compounds, 5f, 5h and 7j displayed higher AChE enzyme inhibitory activities than standard drug, galanthamine, with IC50 values of 1.88, 2.05 and 2.03μM, respectively. Interestingly, all the compounds except for compound 5c displayed higher BChE inhibitories than standard with IC50 values ranging from 3...
