1. Oxytocin receptor gene and racial ingroup bias in empathy-related brain activity.

    NeuroImage 110:22 (2015) PMID 25637390

    The human brain responds more strongly to racial ingroup than outgroup individuals' pain. This racial ingroup bias varies across individuals and has been attributed to social experiences. What remains unknown is whether the racial ingroup bias in brain activity is associated with a genetic polym...

  4. Label-free probe of HIV-1 TAT peptide binding to mimetic membranes.

    PNAS 111(35):12684 (2014) PMID 25136100 PMCID PMC4156756

    The transacting activator of transduction (TAT) protein plays a key role in the progression of AIDS. Studies have shown that a +8 charged sequence of amino acids in the protein, called the TAT peptide, enables the TAT protein to penetrate cell membranes. To probe mechanisms of binding and transl...

  6. 5-HTTLPR polymorphism modulates neural mechanisms of negative self-reflection.

    Cerebral Cortex 24(9):2421 (2014) PMID 23588187

    Cognitive distortion in depression is characterized by enhanced negative thoughts about both environment and oneself. Carriers of a risk allele for depression, that is, the short (s) allele of the serotonin transporter promoter polymorphism (5-HTTLPR), exhibit amygdala hyperresponsiveness to neg...
  7. Does self-construal predict activity in the social brain network? A genetic moderation effect.

    Social Cognitive and Affective Neuroscience 9(9):1360 (2014) PMID 24009354 PMCID PMC4158375

    Neural activity in the social brain network varies across individuals with different cultural traits and different genetic polymorphisms. It remains unknown whether a specific genetic polymorphism may influence the association between cultural traits and neural activity in the social brain netwo...

  10. High speed optical phased array using high contrast grating all-pass filters.

    Optics Express 22(17):20038 (2014) PMID 25321214

    We report a high speed 8x8 optical phased array using tunable 1550 nm all-pass filters with ultrathin high contrast gratings (HCGs) as the microelectromechanical-actuated top reflectors. The all-pass filter design enables a highly efficient phase tuning (1.7 π) with a small actuation voltage (10...

    Chinese Journal of Chromatography 32(6):591 (2014) PMID 25269256

    A method was developed for the determination of amygdalin and its metabolite prunasin in rat plasma after intragastric administration of Maxing shigan decoction. The analytes were identified by ultra-high performance liquid chromatography-tandem quadrupole time of flight mass spectrometry and qu...

  19. Probing symmetry properties of few-layer MoS2 and h-BN by optical second-harmonic generation.

    Nano Letters 13(7):3329 (2013) PMID 23718906

    We have measured optical second-harmonic generation (SHG) from atomically thin samples of MoS2 and h-BN with one to five layers. We observe strong SHG from materials with odd layer thickness, for which a noncentrosymmetric structure is expected, while the centrosymmetric materials with even laye...
  20. Serotonin signaling in the brain of adult female mice is required for sexual preference.

    PNAS 110(24):9968 (2013) PMID 23716677 PMCID PMC3683771

    A role for serotonin in male sexual preference was recently uncovered by our finding that male mutant mice lacking serotonin have lost sexual preference. Here we show that female mouse mutants lacking either central serotonergic neurons or serotonin prefer female over male genital odors when giv...
