Understanding the folding pattern of a single polymer chain within its single crystal will shed light on the mechanism of crystallization. Here, we use the combined techniques of atomic force microscopy (AFM)-based single-molecule force spectroscopy (SMFS) and steered molecular dynamics (SMD) simulations to study the folding pattern of a polyethylene oxide (PEO) chain in its single crystal. Our...

Morphology is crucial to determining the photovoltaic performance of organic solar cells (OSCs). However, manipulating morphology involving only small-molecule donors and acceptors extremely challenging. Herein, a simple terminal alkyl chain engineering process introduced fine-tune towards high-performance all-small-molecule (ASM) OSCs. We successfully chose chlorinated two-dimension benzo[1,2-...

To explore small molecules with ethylene-like biological activity, we conducted a triple response-based assay system for chemical library screening. Among 9600 compounds, we found N-[(1,3,5-trimethyl-1H-pyrazol-4-yl)methyl]-N-methyl-2-naphthalenesulfonamide (EH-1) displayed promising biological activity on inducing a triple response in Arabidopsis seedlings. Chemical synthesis and structure-act...

an attempt is made to show in a straightforward way how a body-fixed frame may be constructed in classical and hence in quantum mechanics for a polyatomic molecule with the aid of which the vibration-rotation behavior of the molecule may be described.

The 38 kD molecule is noncovalently associated with beta 2 microglobulin (beta 2m)-free HLA heavy chain-like molecule, and thus forms a second heterodimer distinct from the clonotypic alpha/beta T cell receptor expressed by the same clone of leukemia cells. This second heterodimer (38 kD/HLA) is variably expressed and appears to be associated with the T3 molecule. We suggest, therefore, that it...

In this study, s-triazine rings (or their derivatives) were introduced into a two-dimensional phase-separated mixed monolayer of hydrocarbon-fluorocarbon chains. The diamino-triazine ring facilitated the absorption deoxyribonucleic acid (DNA) molecules in monolayer. diamino ring-containing copolymers which hydrogenated hydrophobic chain was able to form mixed-phase-separated monolayers when com...

The partial covalent structure of bovine /I-thrombin has been determined by the use of automated Edman degradation and carboxypeptidase digestion of the component polypeptide chains separated by gel filtration following either reduction and carboxymethylation or performic acid oxidation. /I-Thrombin has been found to contain three peptide chains derived by proteolysis of the parent a-thrombin m...

regardless of the known anti-inflammatory potential of heterocyclic antidepressants, the mechanisms concerning their modulating effects are not completely known. in our earlier work, maprotiline, a heterocyclic antidepressants, considerably inhibited infiltration of polymorphonuclear cell leucocytes into the inflamed paw. to understand the mechanism involved, we evaluated the effect of vascular...

Background: Human serum albumin (HSA) is one of the most prominent protein in human blood. Trimethoprim (TMP) is an efficient antibiotic drug for treatment of pneumocystis pneumonia (PCP). Patients with HIV/AIDS and cancer are extremely affected by the disease due to immune system deficiency. Objective: The aim of this study is to evaluate the molecular dynamics simulation (MD) of HSA with TMP...
