The electrohydrodynamic deformation of an emulsion droplet with a clean and particle-covered interface was explored. Here, the electrohydrodynamic deformation was numerically and experimentally demonstrated under the stimuli of moderate and strong electric fields. The numerical method involves the coupling of the Navier-Stokes equation with the level set equation of interface tracking and the governing equations of so-called leaky dielectric theory. The simulation model developed for a clean interface droplet was then extended to a capsule model for densely particle-covered droplets. The experiments were conducted using various combinations of immiscible oils and particle suspensions while the electric field strength ~10⁵ V/m was generated using a high voltage supply. The experimental images obtained by the camera were post-processed using an in-house image processing code developed on the plat-form of MATLAB software. The results show that particle-free droplets can undergo prolate (deformation in the applied electric field direction) or oblate deformation (deformation that is perpendicular to the direction of the applied electric field) of the droplet interface, whereas the low-conductivity particles can be manipulated at the emulsion interface to form a 'belt', 'helmet' or 'cup' morphologies. A densely particle-covered droplet may not restore to its initial spherical shape due to 'particle jamming' at the interface, resulting in the formation of unique droplet shapes. Densely particle-covered droplets behave like droplets covered with a thin particle sheet, a capsule. The deformation of such droplets is explored using a simulation model under a range of electric capillary numbers (i.e., the ratio of the electric stresses to the capillary stresses acting at the droplet interface). The results obtained are then compared with the theory and experimental findings. It was shown that the proposed simulation model can serve as a tool to predict the deformation/distortion of both the particle-free and the densely particle-covered droplets within the small deformation limit. We believe that this study could provide new findings for the fabrication of complex-shaped species and colloidosomes.

Introduction: Venous bed specificity could contribute to differential vulnerability to thrombus formation, and is potentially reflected in mRNA profiles.

Materials and methods: Microarray-based transcriptome analysis in wall and valve specimens from internal jugular (IJV) and saphenous (SV) veins collected during IJV surgical reconstruction in patients with impaired brain outflow. Multiplex antigenic assay in paired jugular and peripheral plasma samples.

Results: Most of the top differentially expressed transcripts have been previously associated with both vascular and neurological disorders. Large expression differences of HOX genes, organ patterning regulators, pinpointed the vein positional identity. The "complement and coagulation cascade" emerged among enriched pathways. In IJV, upregulation of genes for coagulation inhibitors (TFPI, PROS1), activated protein C pathway receptors (THBD, PROCR), fibrinolysis activators (PLAT, PLAUR), and downregulation of the fibrinolysis inhibitor (SERPINE1) and of contact/amplification pathway genes (F11, F12), would be compatible with a thromboprotective profile in respect to SV. Further, in SV valve the prothrombinase complex genes (F5, F2) were up-regulated and the VWF showed the highest expression. Differential expression of several VWF regulators (ABO, ST3GAL4, SCARA5, CLEC4M) was also observed. Among other differentially expressed hemostasis-related genes, heparanase (HPSE)/heparanase inhibitor (HPSE2) were up-/down-regulated in IJV, which might support procoagulant features and disease conditions. The jugular plasma levels of several proteins, encoded by differentially expressed genes, were lower and highly correlated with peripheral levels.

Conclusions: The IJV and SV rely on differential expression of many hemostasis and hemostasis-related genes to balance local hemostasis, potentially related to differences in vulnerability to thrombosis.

In a subset of patients with systemic lupus erythematosus (SLE), antiphospholipid syndrome characterized by thrombocytopenia, thrombosis, recurrent abortion and antiphospholipid antibodies develops. Male (NZW x BXSB) F1 mice are widely used as a model for SLE-associated antiphospholipid syndrome. Our earlier genetic studies showed that one susceptibility allele for thrombocytopenia and associated IgG platelet-binding autoantibodies in male (NZW x BXSB) F1 mice was linked to the BXSB-type polymorphic microsatellite D8Mit96, located in proximity to the gene Plat for tissue-type plasminogen activator (t-PA). In the present studies, sequence analyses for structural and promoter regions of Plat revealed a single nucleotide polymorphism encoding a catalytic domain of t-PA, with an amino acid substitution of anionic Glu366 in NZW for a cationic Lys in BXSB. Progeny studies using NZW x (NZW x BXSB) F1 male backcross mice showed that the BXSB Plat allele was significantly associated with high levels of both platelet-binding antibodies and thrombocytopenia. Furthermore, these two traits appeared to be regulated by a complementary effect of two BXSB alleles; one is linked to Plat and the other to the H-2 complex and the gene for plasminogen. Thus, the BXSB-type Plat may be one susceptibility allele for the multigenic antiphospholipid syndrome seen in (NZW x BXSB) F1 mice. Potential mechanisms are discussed.

The database is a collection of postural data acquired from 10 patients affected by the rare Stargardt's syndrome, all having the ABCA4 gene mutation, and from 10 control healthy subjects. Specifically, the database includes a file (.xlxs) called SubjectsData and 20 datasets (MATLAB structures) containing postural signals. Each subject performed a total of 15 postural tests, 5 postural tests for 3 different conditions ('C': eyes-closed; 'O': eyes-open, still target fixation; 'M': eyes-open, moving target tracking). For each postural test, 11 postural derived signals (the anterior-posterior force, the medio-lateral force, the vertical force, the plate moment about x axis, the plate moment about y axis, the plate moment about z axis, the plate moment about top plate surface about x axis, the plate moment about top plat surface about y axis, the x-coordinate of the center of pressure, the y-coordinate of the center of pressure, and the free moment about z axis) were computed from 8 raw signals, acquired at the Ophthalmic Hospital of Turin, Italy, through an 8-channel Kistler 9286A force platform connected to a Step32 system. Thus, a total of 285 postural signals (120 raw and 165 derived) are available for each subject. The database may be useful to: (1) investigate postural adaptations of patients affected by Stargardt's syndrome; (2) support definition of rehabilitative procedures to reduce postural instability of patients affected by Stargardt's syndrome; and (3) support investigation on visual control of balance in the general population.

In this investigation associations of gene complexes consisting of seven candidate for coronary atherosclerosis (ACE, AGT, NOS3, APOA1, MTHFR, PLAT, F13) with risk factors for CAD (lipid levels, blood pressure, body mass index (BMI)) were studied in Russian population. 94 male patients with CAD proven by angiography and 131 healthy individuals were involved in the case-control study. We observed a significant contribution of gene combinations ("ensembles"). ACE-MTHFR, ACE-F13, ACE-AGT-MTHFR in the variability of the total cholesterol and LDL-cholesterol levels. The "Ensembles" ACE-AGT-MTHFR were associated with variability of three atherogenic risk factors (LDL, BMI, cholesterol total). Two-locus gametic disequilibrium was analysed between gene polymorphisms. NOS3 and ACE, NOS3 and APOA1 were in gametic disequilibrium in the control group. Polymorphic markers of ACE and F13, NOS3 and F13, ACE and PLAT loci were in gametic disequilibrium in the patients. Both approaches (association analysis and gametic disequilibrium) revealed the same gene combinations contributing to the CAD risk factors. NOS3 and APOA1 markers were in gametic disequilibrium in the patients and both of them were associated with LDL. F13 and AGT were associated with systolic and diastolic blood pressure and two-locus gametic disequilibrium between F13 and AGT polymorphisms observed in the patients.

The plat castable ceramic crown was made with investment material prepared in our college with our own casting technique by a Chinese-made casting machine. The accuracy and fitness of the crown were studied and appraised. Results show that the margin of fitness is 46 microns and that the cement film thickness of the dies in the spacer material group is 65.13 microns. Hence the results are satisfactory. The Plat castable ceramic crown might be used in clinical dentistry.

BACKGROUND

Ovarian stimulation protocols have been described to induce prothrombotic phenotype through alterations of both coagulation and fibrinolysis pathways. We investigated fibrinolytic changes during ovarian stimulation through a global test (CLT) and PAI-1 and TAFI concentrations at different times of ovarian stimulation procedure, and the influence of polymorphisms in genes encoding for fibrinogen chains (FGA, FGB, FGG), t-PA (PLAT), TAFI (CBP2), FXIII (FXIIA1, FXIIIB), plasminogen (PLG) and PAI-1 (PAI1) on their intermediate phenotype.

METHODS

We evaluated fibrinolytic and genetic parameters in 110 infertile women undergoing ovarian stimulation procedure (in vitro fertilization, IVF or intracytoplasmic sperm injection, ICSI). All women were observed during the mid-luteal phase of cycle (T(0)) and on day 5 (T(1)), 7 (T(2)) and 9 (T(3)) of the ovarian stimulation.

RESULTS

Significant changes in fibrinolytic parameters from T(0) to T(3) of ovarian stimulation were found (CLT p=0.003; TAFI p=0.009 and PAI-1 p=0.003). CLT values, TAFI and PAI-1 concentrations significantly increased from baseline to T(1) (p<0.0001, p=0.01, p=0.005, respectively)(,) and decreased at T(2,) but remained higher than those at T(0). Moreover, at baseline overweight women showed longer CLT, higher TAFI and PAI-1 concentrations than normal weight women, as well as at T(1) two-fold longer CLT and higher PAI-1 concentrations were observed (p=0.001 and p=0.05, respectively). Significant differences of TAFI and PAI-1 concentrations during ovarian stimulation according to TAFI and PAI1 polymorphisms were observed.

CONCLUSIONS

This study shows alterations of fibrinolysis and suggests the contribution of TAFI and PAI1 genes in modulating fibrinolysis changes during the ovarian stimulation cycle.

Lipoxygenases (LOXs) catalyze the (per) oxidation of fatty acids that serve as important mediators for cell signaling and inflammation. These reactions are initiated by a C-H activation step that is allosterically regulated in plant and animal enzymes. LOXs from higher eukaryotes are equipped with an N-terminal PLAT (Polycystin-1, Lipoxygenase, Alpha-Toxin) domain that has been implicated to bind to small molecule allosteric effectors, which in turn modulate substrate specificity and the rate-limiting steps of catalysis. Herein, the kinetic and structural evidence that describes the allosteric regulation of plant and animal lipoxygenase chemistry by fatty acids and their derivatives are summarized.

Keywords: C-H activation; hydrogen tunneling; kinetic isotope effects; protein allostery; substrate selectivity.

OBJECTIVE

To observe whether additional penehyclidine hydrochloride (PHC) in mechanical ventilation produces therapeutic effect on oleic acid (OA) induced acute lung injury (ALI) in canine.

METHODS

Seventeen male canines (weighing 12-17 kg) were divided into control group (n=5), OA group (n=6) and PHC group (n=6). ALI model was developed by central venous injection of OA in canines of OA and PHC groups. ALI model was kept steady in air, all groups received mechanical ventilation 90 minutes later. Three groups received normal saline 0.25 mg/kg without injection of OA (control group), normal saline 0.25 mg/kg after injection of OA (OA group) and PHC 0.25 mg/kg after injection of OA (PHC group) respectively at 0 h (90 minutes after onset time of ALI/ARDS). The heart rate (HR), mean arterial pressure (MAP), mean pulmonary arterial pressure (MPAP), central venous pressure (CVP), pulmonary artery wedge pressure (PAWP), artery blood gas analysis, cardiac output (CO), extravascular lung water index (EVLWI), FiO2 and VT were observed respectively at baseline, onset time of ALI/ARDS and 0 h, then again at 1 hour intervals for 6 hours. Besides the above, airway peak pressure (Ppeak), airway plat pressure (Pplat), mean airway pressure (Pmean) and positive end-expiratory pressure (Peep) were also observed each hour during 1-6 hours. Oxygenation index (OI), pulmonary vascular resistance (PVR), systemic vascular resistance (SVR), alveolar-arterial differences for O2 (AaDO2) and dynamic lung compliance (DLC) were calculated and pulmonary tissue was collected for histopathologic investigation and dry wet weight ratio (WDR) test.

RESULTS

The functional parameters of PHC group were improved when compared those of OA group, but there was no significant difference; WDR of independent region of three groups were 80.42% +/- 3.48%, 82.67% +/- 4.01% and 82.26% +/- 1.43% respectively; WDR of dependent region of three groups were 80.51% +/- 3.60%, 83.71% +/- 1.98% and 82.57% +/- 1.08% respectively. WDR of PHC group were obviously improved when compared with those of OA group, but there was no significant difference. Independent and dependent regions of PHC group were significantly improved when compared those of OA group in histopathologic scores, alveolar edema, inflammatory infiltration and over-distension (P < 0.01).

CONCLUSIONS

Additional PHC in mechanical ventilation produces obvious therapeutic effect on OA induced acute lung injury in canine.

To get an understanding of the microflora of endophytic actinomycetes in Ligusticum chuanxiong,and to obtain the resource of antagonistic strains against Ligusticum chuanxiong root rot disease.

Actinomycetes in stem nodes and rhizomes of Ligusticum chuanxiong were isolated and purified by a series of means,namely tissue block method, homogenate technique and plat streaking method. Further, dual culture and inhibition zone method were employed to test the antagonistic activity of these strains. To identify strains with potential precisely,both microscopic observation and DNA sequencing were conducted.

83 strains of Ligusticum chuanxiong endophytic actinomycetes were identified, which consisted of 13 species groups. Among all of them,species identified as Streptomyces scopuliridis( KF600747. 1), Streptomyces griseorubiginosus( AB706352. 1) and Streptomyces agglomeratus( LC055413. 1) showed antagonistic activities against four kinds of pathogenic fungi of Ligusticum chuanxiong root rot disease.

Actinomycetes which belong to Griseorubroviolaceus groups of streptomyce are potential biocontrol microbes to Ligusticum chuanxiong root rot,showing importance to the production of Chuanxiong Rhizoma.

The liver decellularized scaffolds applied with the circulation perfusion device could provide a well 3D plat form for culture of hepatocytes.

Metabolic profiling of breath analysis involves processing, alignment, scaling and clustering of thousands of features ex-tracted from Gas Chromatography Mass spectrometry (GC-MS) data from hundreds of participants. The multi-step data processing is complicated, operator error-prone and time-consuming. Automated algorithmic clustering methods that are able to cluster features in a fast and reliable way are necessary. These accelerate metabolic profiling and discovery plat-forms for next generation medical diagnostic tools. Our unsupervised clustering technique, VOCCluster, prototyped in Py-thon, handles features of deconvolved GC-MS breath data. VOCCluster was created from a heuristic ontology based on the observation of experts undertaking data processing with a suite of software packages. VOCCluster identifies and clusters groups of volatile organic compounds (VOCs) from deconvolved GC-MS breath with similar mass spectra and retention index profiles. VOCCluster was used to cluster more than 15,000 features extracted from 74 GC-MS clinical breath samples obtained from participants with cancer before and after a radiation therapy. Results were evaluated against a panel of ground truth compounds and compared to other clustering methods (DBSCAN and OPTICS) that were used in previous metabolomics studies. VOCCluster was able to cluster those features into 1081 groups (including endogenous, exogenous compounds and instrumental artefacts) with an accuracy rate of 96% (± 0.04 at 95% confidence interval).

Chemosensitivity was analyzed by mouse subrenal capsule assay (SRCA) in 103 human melanoma metastases 79 of which were also analyzed by DNA flow cytometry. The most effective combination was dacarbazine, vincristine, and carmustine (DOB), followed by cisplatin plus etoposide (Plat-VP16). By the original criteria of the assay, 35% of tumors were sensitive to DOB treatment while 15% responded to Plat-VP16. Chemosensitivity of DNA diploid and aneuploid tumors showed no significant difference; 35% of the aneuploid tumors were sensitive to DOB and 19% to Plat-VP16, whereas 41% and 13% respectively of the diploid tumors were sensitive. An association between DNA index and chemosensitivity was observed. Growth of the implant was observed in 44% of tumors with a DNA index above 1.5 receiving DOB treatment, whereas only 12% of tumors with an aneuploid DNA index < or = 1.5 grew. No significant difference was observed in the SPF of chemotherapy sensitive and insensitive tumors, though a tendency to lower SPF was observed in sensitive tumors.

We have analysed the chemosensitivity of 121 human melanoma metastases in the 6-day mouse subrenal capsule assay (SRCA). A total of 13 different chemotherapy regimens were analysed in four successive series. By the original criteria of the assay, 75% of tumours were sensitive to at least one regimen. The most effective combinations, giving sensitivity rates>> 40%, were of dacarbazine, vincristine, and BCNU (DOB) with or without metronidazole, followed by cisplatin plus etoposide (Plat-VP16) combined with interferon. On the basis of the SRCA screening we developed a four-drug chemotherapy regimen combined with interferon for metastatic melanoma. Retrospectively analysed the assay correctly identified 77% of clinical responders and 54% of clinical non-responders. The overall predictive accuracy was 65%. Despite the limitations of the assay, it can be used for screening new drugs or combinations.

The purpose of this study was to identify critical genes associated with septic multiple trauma by comparing peripheral whole blood samples from multiple trauma patients with and without sepsis. A microarray data set was downloaded from the Gene Expression Omnibus (GEO) database. This data set included 70 samples, 36 from multiple trauma patients with sepsis and 34 from multiple trauma patients without sepsis (as a control set). The data were preprocessed, and differentially expressed genes (DEGs) were then screened for using packages of the R language. Functional analysis of DEGs was performed with DAVID. Interaction networks were then established for the most up- and down-regulated genes using HitPredict. Pathway-enrichment analysis was conducted for genes in the networks using WebGestalt. Fifty-eight DEGs were identified. The expression levels of PLAU (down-regulated) and MMP8 (up-regulated) presented the largest fold-changes, and interaction networks were established for these genes. Further analysis revealed that PLAT (plasminogen activator, tissue) and SERPINF2 (serpin peptidase inhibitor, clade F, member 2), which interact with PLAU, play important roles in the pathway of the component and coagulation cascade. We hypothesize that PLAU is a major regulator of the component and coagulation cascade, and down-regulation of PLAU results in dysfunction of the pathway, causing sepsis.

Background. Acute respiratory distress syndrome (ARDS) mortality is lower among subjects participating in randomized controlled trials (RCT) versus those in observational studies. Excluding potential subjects with inordinately high mortality risk is necessary to prevent masking the impact of potentially effective treatments. We inquired whether observed mortality differed between RCT-eligible and RCT-ineligible subjects managed with varying degrees of lung-protective ventilation (LPV) in a non-research setting.Methods. This single-center, retrospective, observational study utilized quality assurance data for monitoring LPV practices based upon National Institutes of Health ARDS Network (ARDSNet) protocols. Between 2002-2017, 1975 subjects meeting 1994 consensus criteria for ALI/ARDS (later reclassified by the Berlin definition) were prospectively identified and classified as RCT-eligible or RCT-ineligible based upon the original ARDSNet exclusion criteria for co-morbidities or moribund condition. Demographic and physiologic data from the day of ARDS onset and outcome data were. Survival was modeled by mixed-effect Cox proportional hazard model adjusted for age, both illness and lung injury severity plateau pressure (P_plat) and formal use of the ARDSNet ventilator protocol. The primary outcome of interest was all-cause mortality during the first 90 days following ARDS onset.Results. Day 90 mortality was 27.6% in RCT-eligible patients vs. 50.4% in RCT-ineligible patients: HR (95% CI) of 0.47 (0.41-0.54), P < 0.001. Regardless of RCT-eligibility or ineligibility criteria, achieving a P_plat < 30 cmH₂O was associated with lower mortality. Overall, mortality risk was lower in patients managed by protocol vs. clinician-directed LPV (HR = 0.60 (95%CI = 0.52 - 0.69), p < 0.001), even among those in whom P_plat was < 30 cmHH₂O (HR = 0.64 (0.54-0.76), p<0.001).Conclusion. Mortality in non-research, RCT-eligible patients was substantially lower compared to RCT-ineligible patients. Managing non-research ARDS patients by keeping Pplat < 30 cmH₂O and formal use of a lung-protective ventilation protocol significantly reduces mortality risk.

Background and purpose: Although pain is one of the most common symptoms of diseases, it is often mismanaged due to limited access to painkillers and ineffectiveness, unacceptable side effects, or the possibility of abuse. However, an alternative approach to existing analgesics is to indirectly increase endogenous pain relief pathways by neprilysin (an enkephalinase) inhibitors. This enzyme breaks down and inactivates enkephalin, dynorphin, endorphins, and their derivatives.

Purpose: Herbal medicine is one of crucial symbols of Chinese national medicine. Investigation on molecular responses of different herbal strategies against viral myocarditis is immeasurably conducive to targeting drug development in the current international absence of miracle treatment.

Methods: Literature retrieval platforms were applied in the collection of existing empirical evidences for viral myocarditis-related single-herbal strategies. SwissTargetPrediction, Metascape, and Discovery Studio coordinating with multidatabases investigated underlying target genes, interactive proteins, and docking molecules in turn.

Results: Six single-herbal medicines consisting of Huangqi (Hedysarum Multijugum Maxim), Yuganzi (Phyllanthi Fructus), Kushen (Sophorae Flavescentis Radix), Jianghuang (Curcumaelongae Rhizoma), Chaihu (Radix Bupleuri), and Jixueteng (Spatholobus Suberectus Dunn) meet the requirement. There were 11 overlapped and 73 unique natural components detected in these herbs. SLC6A2, SLC6A4, NOS2, PPARA, PPARG, ACHE, CYP2C19, CYP51A1, and CHRM2 were equally targeted by six herbs and identified as viral myocarditis-associated symbols. MCODE algorithm exposed the hub role of SRC and EGFR in strategies without Jianghuang. Subsequently, we learned intermolecular interactions of herbal components and their targeting heart-tissue-specific CHRM2, FABP3, TNNC1, TNNI3, TNNT2, and SCN5A and cardiac-myocytes-specific IL6, MMP1, and PLAT coupled with viral myocarditis. Ten interactive characteristics such as π-alkyl and van der Waals were modeled in which ARG111, LYS253, ILE114, and VAL11 on cardiac troponin (TNNC1-TNNI3-TNNT2) and ARG208, ASN106, and ALA258 on MMP1 fulfilled potential communicating anchor with ellagic acid, 5α, 9α-dihydroxymatrine, and leachianone g via hydrogen bond and hydrophobic interaction, respectively.

Conclusions: The comprehensive outcomes uncover differences and linkages between six herbs against viral myocarditis through component and target analysis, fostering development of drugs.

Murine peritoneal macrophages, human fibroblasts and human ovarian teratocarcinoma cells were treated with CDDP (10 micrograms/ml) and "poly-plat" (10 micrograms/ml) for 2 h and cultured for 2-96 h. After "poly-plat" treatment macrophages developed cytoplasmic extensions much faster and secreted higher levels of interleukin-2 (IL-2), compared to CDDP. "Poly-plat" treated human fibroblasts demonstrated a significant release of IL-2 (138 pg/ml), compared to CDDP (64 pg/ml) or the untreated normal cells (31 pg/ml) after 8 h. Correspondingly there was a 53% increase in cells after "poly-plat" treatment compared to only 37% after CDDP. However, human ovarian teratocarcinoma cells didn't show any significant increase in IL-2 levels after "poly-plat" treatment and there was instead a decrease of 15% in cell numbers at 8 h. Based on our studies, we propose that "poly-plat" is more effective in activation of the macrophages and human fibroblasts in terms of IL-2, but not so with human ovarian teratocarcinoma cells.

The study was targeted to the investigation of possibilities of using in immunological analysis the sols on basis of bivalent cobalt compounds as a catalytic marker to ensure the trusted visual registration of analysis results in immunology reactions plats. The results of comparative evaluation of immune-enzyme and immune catalytic tests on the basis of several commercial diagnostic test systems of various national manufacturers are presented. The conclusion is derived that by the sensitivity and specificity the cobaltferous immunosols are not inferior to immuneperoxidase conjugated metabolites and even have an advantage due to the relative simplicity of immunosol preparation and the possibility of trusted non-instrument registration of results. The application of cobaltferous immunosols permits to develop the diagnostic test systems with trusted visual registration of results following the "yes-no" principle to ensure the immunodiagnostics in poorly equipped laboratories.

Congenital myasthenic syndromes are caused by mutations in molecules expressed at the neuromuscular junction. Collagen Q (ColQ) makes a triple helical structure and anchors the catalytic subunit of acetylcholinesterase (AChE) to the synaptic basal lamina in the form of asymmetric AChE. Mutations in the collagen Q gene (COLQ) cause endplate AChE deficiency. As an initial step to develop a novel therapeutic strategy for endplate acetylcholinesterase deficiency, we expressed AChE species in cultured cells using retrovirus and adeno-associated virus (AAV). The retroviral vectors carried human ACHE and COLQ either in a single construct (EF1alpha-ACHE-IRES-COLQ) or in two separate constructs (EF1alpha-ACHE and EF1alpha-COLQ). We produced high-titer retroviruses using the PLAT-E retrovirus packaging cells. We also confirmed expression of asymmetric AChE in the PLAT-E cells. We infected NIH3T3 and confirmed expression of the transgenes by RT-PCR. The AAV vector carried human COLQ-IRES-EGFP downstream of the CMV promoter (pAAV-CMV-COLQ-IRES-EGFP). We produced recombinant AAV using HEK293 cells carrying pDF6 encoding the AAV6 capsid gene. We infected AAVHT1080 cells and confirmed expression of COLQ by RT-PCR and EGFP by flow cytometry. We are currently trying to achieve further higher expression levels of transgenes in cultured cells to make the current strategy applicable to an animal model.

The last decades have seen tremendous progress in quantitative understanding of phonon transport, which is critical for the thermal management of various functional devices and the proper optimization of thermoelectric materials. In this work, using first-principles based calculation combined with non-equilibrium Green's function and phonon Boltzmann transport equation, we provide a systematic study on the phonon stability and phonon transport of monolayer boron sheet with honeycomb, graphene-like structure (graphene-like borophene) in both ballistic and diffusive regimes. For free-standing graphene-like borophene, phonon instabilities occur near the centre of Brillouin zone, implying elastic instability. Investigation of the electronic structures shows that the phonon instability is due to the deficiency of electrons. Our first-principles results show that with net charge doping and in-plane tensile strain, the graphene-like borophene is becoming thermodynamic stable in ideal plat nature, because the bonding characteristic is modified. At room temperature, the ballistic thermal conductance of graphene-like borophene 7.14 nWK-1 nm-2) is higher than that of graphene (4.1 nWK-1 nm-2), due to high phonon transmission. However, its diffusive thermal conductivity is two orders of magnitude lower than graphene, because the phonon relaxation time is dramatically reduced comparing with its carbon counterpart. Although the phonon group velocity and phonon anharmonicity are comparable with that of graphene, the suppressed phonon space results in dramatically strong phonon-phonon scattering. These thermal transport characteristics in both ballistic and diffusive regimes are of fundamental and technological relevance and provide guidance for applications of boron based nanomaterials in which their thermal conduction is major concern.
