Oral vaccination with recombinant Saccharomyces cerevisiae expressing Micropterus salmoides rhabdovirus G protein elicits protective immunity in largemouth bass.

Micropterus salmoides rhabdovirus (MSRV) is one of the main pathogens of largemouth bass, leading to serious economic losses. The G protein, as the only envelope protein present on the surface of MSRV virion, contains immune-related antigenic determinants, thereby becoming the primary target for the design of MSRV vaccines. Here, we displayed the G protein on the surface of yeast cells (named EBY100/pYD1-G) and conducted a preliminary assessment of the protective efficacy of the recombinant yeast vaccine. Upon oral vaccination, a robust immune response was observed in systemic and mucosal tissue. Remarkably, following the MSRV challenge, the relative percent survival of EBY100/pYD1-G treated largemouth bass significantly increased to 66.7 %. In addition, oral administration inhibited viral replication and alleviated the pathological symptoms of MSRV-infected largemouth bass. These results suggest that EBY100/pYD1-G could be used as a potential oral vaccine against MSRV infection.

Supramolecular Room Temperature Phosphorescent Materials Based on Cucurbit[8]uril for Dual Detection of Dodine.

In recent years, host-guest interactions of macrocycles have attracted much attention as an emerging method for enhancing the intersystem crossing of pure organic room-temperature phosphorescence. In this work, we utilize cucurbit[8]uril (Q[8]) to specifically recognize synthetic bromophenyl pyridine derivatives (BPCOOH) to construct a highly stable charge-transfer dimer, where the bromophenyl pyridine moiety of BPCOOH is encapsulated by Q[8] in a 1:2 host/guest ratio. The assemblies exhibit specific recognition and detection properties for dodine on both fluorescence and phosphorescence spectra. Subsequently, the solid films were prepared by introducing carboxymethylcellulose sodium into the assemblies, which greatly enhanced its RTP performance by increasing the noncovalent bonding interactions, enabling the visualization of high-strength RTP and quantitative testing of the solid state. Finally, this material was used for the application of portable indicator papers to achieve rapid and visualized detection of dodine in daily life, which provides more possibilities for the potential applications of cucurbit[n]uril-based room-temperature phosphorescence material.

Cucurbit[10]uril-Based Orthogonal Supramolecular Polymers with Host-Guest and Coordination Interactions and Its Applications in Anion Classification.

A novel orthogonal supramolecular polymer (Q[10]-TPDPB-Lu3+) in a host-guest ratio of 2:1 was successfully constructed utilizing the specificity and excellent cavity matching of Q[10] with the tripyridine derivatives (TPDPB). Significantly, non-covalent interactions between Q[10]'s hydrophobic cavities and Lu3+ were used to induce charge transfer of TPDPB to TPDPB and TPDPB to Lu3+, resulting in the construction of structurally interesting orthogonal assemblies with excellent fluorescence properties. Finally, the Q[10]-TPDPB-Lu3+ assemblies were shown to have good recognition and classification of strong and weak acid anions as well as iodide anions, and the classification was accompanied by a clear fluorescence emission change allowing visual observation.

Cucurbit[10]uril-mediated Supramolecular Assembly for Optically Tunable Dimers and Near White-light Emissive Materials.

Cucurbit[10]uril (Q[10]), the cucurbit[n]uril with a large cavity, exhibits several new features in the development of the host-guest complex. Thus, based on Q[10] and π-conjugated molecule, oligo(p-phenylenevinylene) derivative (OPVCOOH), the host-guest complexes with three different interaction ratios of 1 : 2, 2 : 2, and 3 : 2 assemblies (Q[10]: guest) were fabricated. Depending on the host/guest ratio, the emission color of these complexes ranged from blue to yellow-green. The extra Fe2+ coordinated with a bare carboxyl group of the Q[10]-OPVCOOH (3 : 2) assembly, obstructing its rotaxane structure and forming Q[10]-OPVCOOH-Fe2+ assembly, which may be used as a coating for near-white LED bulbs.

Analysis of the Effect of Nine Consecutive Years' Intensive Management and Number of Times Achieving the Target Control on Endpoint Events in T2DM Patients in Sanlitun Community Health Service Center in Beijing.

OBJECTIVE: To investigate the effect of intensive management and achieving the target control more than 3 times on endpoint events during 9 consecutive years' annual assessment in type 2 diabetes (T2DM) patients in the Sanlitun Community Health Service Center in Beijing, including blood glucose, blood pressure, lipids profiles, and the joint target control. METHODS: In Beijing Community Diabetes Study (BCDS), 224 patients with T2DM from the Sanlitun Community Health Service Center were enrolled in 2008. All patients were randomly assigned to the intensive management group (n = 113) and the standard management group (n = 113) and the standard management group (. RESULTS: During the nine-year follow-up, the abscission number was 35 (14.29%), among which 14 (12.39%) was in the intensive management group and 21 (18.92%) was in the standard management group. The incidence of diabetic retinopathy (6 cases, 5.41%) and diabetic nephropathy (13 cases, 11.71%) in the standard management group was significantly higher than that in the intensive management group (1 case, 0.88%; 5 cases, 4.42%), respectively (P < 0.05). However, there were no significant differences on the other endpoint events between the two groups (P < 0.05). However, there were no significant differences on the other endpoint events between the two groups (P < 0.05). However, there were no significant differences on the other endpoint events between the two groups (P < 0.05). However, there were no significant differences on the other endpoint events between the two groups (P < 0.05). However, there were no significant differences on the other endpoint events between the two groups (. CONCLUSIONS: The intensive management can effectively reduce the occurrence of microvascular complications. The incidence of all-cause death and the other endpoint events decreased in T2DM patients who achieved the joint target control more than 3 times during the nine-year management, which improved survival time and life quality. This trial is registered with ChiCTR-TRC-13003978 and ChiCTR-OOC-15006090.
