Abstract: Surface-modified glass and polymer membrane interfaces form high-electrical resistance seals that can be used in microfluidic valves and array devices tailored for electrophysiological measurements. The incorporation of high seal resistance valves into the array device allows only the desired electrophysiological signal to be detected by a patch clamp amplifier, enabling parallel experiments with one patch clamp amplifier, which can greatly improve the cost efficiency. To achieve the desired high seal resistance, surface modification was performed on the glass components to increase the interaction between the glass and the membrane surfaces. The valves exhibit seal resistance of >500 G? after modification, which is 100× higher than reported for unmodified valves.

Abstract: Disclosed herein are methods of identifying infections, such as methods of identifying bacterial infections which utilize whole metagenome sequence analysis to sequence the entire wound microbiome of clinical samples. The disclosed methods use fast k-mer based sequence analysis, predictive modeling, and Bayesian network analysis, to analyze bacterial metagenomic sequence compositions in conjunction with clinical factors to stratify communities of bacteria into healing versus non-healing clusters. The methods of identifying infections can include performing molecular analysis of a patient wound sample, preparing the data obtained from the molecular analysis, diagnosing the wound sample and/or prognosing the wound sample. The disclosed methods can also be used to identify protein function as well as novel biomarkers.

Abstract: Methods and compositions for activating TORC1 aggregate formation in a fungi or a parasite, wherein TORC1 aggregate formation inhibits growth of the fungi or parasite. TORC1 aggregate formation may be activated using small molecules or other agents, and said agents may be used to treat or prevent a disease or condition associated with the fungi and parasite. The agent may target Kog1 of TORC1, e.g., the agent may directly or indirectly inhibit Kog1 leading to aggregation of the TORC1 complex.

Abstract: Methods and compositions for rapidly replacing cMyBP-C in sarcomeres featuring the creation of Spy-C mice, which are mice genetically engineered to express cMyBP-C with a protease recognition site and SpyTag peptide introduced into the cMyBP-C gene. In permeabilized myocytes from the Spy-C mice, the cMyBP-C protein can be cleaved at the protease recognition site, and the N-Terminus of cMyBP-C can be removed while the C-terminus remains anchored to the thick filament. A new peptide featuring the SpyCatcher sequence can be covalently bonded to the remaining portion of cMyBP-C, thereby creating a modified cMyBP-C protein. The methods and compositions of the present invention allow for the reconstitution of full-length cMyBP-C at the precise position of native cMyBP-C in the sarcomere and allow for a variety of modifications to be introduced to cMyBP-C in situ.

Abstract: The subject invention pertains to a modified MC1R peptide ligand comprising a peptide that is a melanocortin 1 receptor (MC1R) ligand and a functionality or linker, such as a click functionality, for conjugation to a surface or agent. The modified MC1R peptide ligand can be coupled, e.g., via a click reaction with a complementary click functionality attached, to a moiety to form an MC1R-targeted agent. Drugs, contrast agents, polymers, particles, micelles, surfaces of larger structures, or other moieties can be targeted to the MC1R. The subject invention also pertains to a MC1R peptide ligand-micelle complex comprising a peptide that is a melanocortin 1 receptor ligand connected via a click reaction product to a micelle. The micelle is stable in vivo and can target melanoma tumor cells by association of the peptide ligand with the MC1R or the tumor and selectively provide a detectable and/or therapeutic agent (such as an imageable contrast agent and/or anti-cancer agent) selectively to the tumor cell.

Abstract: Various examples are provided related to scanning tunneling thermometers and scanning tunneling microscopy (STM) techniques. In one example, a method includes simultaneously measuring conductance and thermopower of a nanostructure by toggling between: applying a time modulated voltage to a nanostructure disposed on an interconnect structure, the time modulated voltage applied at a probe tip positioned over the nanostructure, while measuring a resulting current at a contact of the interconnect structure; and applying a time modulated temperature signal to the nanostructure at the probe tip, while measuring current through a calibrated thermoresistor in series with the probe tip. In another example, a device includes an interconnect structure with connections to a first reservoir and a second reservoir; and a scanning tunneling probe in contact with a probe reservoir.
