Background: Two randomized phase III trials (EORTC55971 and CHORUS) showed similarprogression-free and overall survival in primary or interval debulking surgery in ovariancancer, however both studies had limitations with lower rate of complete resection and lack ofsurgical qualifications for participating centers. There is no consensus on whether neoadjuvantchemotherapy followed by interval debulking surgery (NACT-IDS) could be a preferred approachin the management of advanced epithelial ovarian cancer (EOC) in the clinical practice. Methods: The Asian SUNNY study is an open-label, multicenter, randomized controlled,phase III trial to compare the effect of primary debulking surgery (PDS) to NACT-IDS instages IIIC and IV EOC, fallopian tube cancer (FTC) or primary peritoneal carcinoma (PPC). The hypothesis is that PDS enhances the survivorship when compared with NACT-IDS inadvanced ovarian cancer. The primary objective is to clarify the role of PDS and NACT-IDS inthe treatment of advanced ovarian cancer. Surgical quality assures include at least 50% of nogross residual (NGR) in PDS group in all centers and participating centers should be nationalcancer centers or designed ovarian cancer section or those with the experience participatingsurgical trials of ovarian cancer. Any participating center should be monitored evaluatingthe proportions of NGR by a training set. The aim of the surgery in both arms is maximalcytoreduction. Tumor burden of the disease is evaluated by diagnostic laparoscopy orpositron emission tomography/computed tomography scan. Patients assigned to PDS groupwill undergo upfront maximal cytoreductive surgery within 3 weeks after biopsy, followed by6 cycles of standard adjuvant chemotherapy. Patients assigned to NACT group will undergo 3cycles of NACT-IDS, and subsequently 3 cycles of adjuvant chemotherapy. The maximal timeinterval between IDS and the initiation of adjuvant chemotherapy is 8 weeks. Major inclusioncriteria are pathologic confirmed stage IIIC and IV EOC, FTC or PPC; ECOG performancestatus of 0 to 2; ASA score of 1 to 2. Major exclusion criteria are non-epithelial tumors as wellas borderline tumors; low-grade carcinoma; mucinous ovarian cancer. The sample size is 456subjects. Primary endpoint is overall survival.

Tyrosinase inhibitors are clinically effective for treating some dermatological disorders related to melanin hyperpigmentation. Accordingly, the discovery and development of tyrosinase inhibitors have great value in the pharmaceutical and cosmetic industry. Here, a novel tyrosinase inhibitor, 6′-O-cinnamoyl-helicid (helicid cinnamylate) was successfully synthesized by a simple and effective biocatalytic approach with Aspergillus oryzae cells. Investigation of the effects of several key variables on helicid cinnamylate synthesis found that the reaction conversion, reaction rate and regioselectivity reached 99%, 9.40 mM/h and > 99%, respectively, at the optimal conditions with anhydrous acetone as the solvent, whole-cell concentration of 40 mg/mL, and the molar ratio of vinyl cinnamate to helicid of 10 at 45°C. The whole-cells retained 68.87% of its initial activity after reusing for seven batches, indicating a potent application potential in non-aqueous biocatalytic systems. It was worth noting that helicid cinnamylate demonstrated a more potent tyrosinase inhibitory activity with an IC50 value of 3.55 mM than helicid (IC50 = 4.48 mM) and arbutin (IC50 = 5.48 mM), which suggest that helicid cinnamylate could be developed as a more potential tyrosinase inhibitor. In conclusion, this study provides a novel whole-cell catalytic approach for the synthesis of helicid cinnamylate and insight into its application as a tyrosinase inhibitor.

The first example of lead compound from Pb(NO_3)_2 and H3L N-heterocyclic ligand (H_3L = (HO_2C)_2(C_3N_2)(C_3H_7)CH_2(C_6H_4)(C_6H_3)CO_2H), [Pb_4(L')_4]·5H_2O 1 (L' = OOC(C_3H_7)(C_3N_2)CH_2(C_6H_4)(C_6H_3)COO), has been obtained under hydrothermal condition by decarboxylation, and characterized by elemental analysis, IR, TGDTA,and single-crystal X-ray diffraction. Compound 1 possesses a rare two-dimensional upper-lower offset terrace-like layer structure. In 1, crystallographic distinct Pb(II) ion adopts five-coordination geometry, and two lattice water molecules occupy the voids between 2-D layers. Results of solid state fluorescence measurement indicate that the emission band 458 nm may be assigned to π*-n and π*-π electronic transitions within the aromatic systems of the ligand L', however, the emission bands centred at 555 nm, 600 nm and 719 nm may be derived from phosphorescent emission (λexcitation = 390 nm).

Two metal compounds, $[Co(phen)_2(H_2O)_2]{\cdot}2H_2SIP{\cdot}2H_2O$ 1 and $[Ni(phen)_3]{\cdot}2H_2SIP{\cdot}3H_2O$ 2, have been obtained by incorporating 1,10-phenanthroline (phen) and 5-sulfoisophthalic acid monosodium salt ($NaH_2SIP$) ligands under hydrothermal conditions. Meanwhile, the two compounds were characterized by element analysis, IR, XRD, TG-DTA and single-crystal X-ray diffraction. Both 1 and 2 present 3D supramolecular structures via O-H${\cdots}$O hydrogen bond interactions. Luminescent properties for 1 and 2 were also studied. The compound 1 has two fluorescence emission peaks centered at 398 nm attributed to the intraligand emission from the SIP ligand and at 438 nm assigned to the combined interaction of intraligand ${\pi}^*-{\pi}$ transitions of the phen ligand and ligand-to-metal-charge-transfer (LMCT) transitions (${\lambda}_{ex}$ = 233 nm). The compound 2 shows one emission band centered at 423 nm with a shoulder peak at 434 nm which may be originated from the intraligand ${\pi}^*-{\pi}$ transitions of the phen ligand (${\lambda}_{ex}$ = 266 nm).

The ecological distribution and activities of soil microbes can refl ect the infl uence of environmental factors on microbes andchanges in soil fertility. Understanding the community structure of the soil microbes is of great importance to maintaining soilhealth in ancient mulberry plantation ecosystems. In this study, the population structure of soil microorganisms in diff erentages of mulberry plantations was analyzed using high-throughput sequencing technology. A total of 1616, 1568, 1379 and1477 operational taxonomic units were acquired from samples of 3Y (3-year-old), 35Y (35-year-old), 200Y (200-year-old)and 600Y (600-year-old) soils, respectively. The results exhibited that the highest community diversity was found in 35Ysoil, followed by 200Y soil, and showed that the stand age strongly infl uenced the community structure of soil bacteria. Atotal of 23 phyla were detected in 12 samples, and the genus of bacteria that predominated the diff erent stand ages mainlyincluded; Phenylobacterium , Cohnella , Lactococcus , Sphingomonas , Bacillus , and Microbispora . The relative abundanceof Phenylobacterium accounts for 22.6–53.5% of the total abundance. This study showed that the richness and diversity ofthe soil bacteria decreased as the stand age increased in ancient mulberry plantations.

Since the variations of illumination, the irregular changes of human shapes, and the partial occlusions, multiple person tracking is a challenging work in computer vision. In this paper, we propose a graph clustering method based on spatio-temporal information of moving objects for multiple person tracking. First, the part-based model is utilized to localize individual foreground regions in each frame. Then, we heuristically leverage the spatio-temporal constraints to generate a set of reliable tracklets. Finally, the graph shift method is applied to handle tracklet association problem and consequently generate the completed trajectory for individual object. The extensive comparison experiments demonstrate the superiority of the proposed method.

Hydrothermal reaction of zinc(II) salts with 5-sulfoisophthalic acid monosodium salt (NaO3SC6H3-1,3-(COOH)2, NaH2-SIP) and 1,10-phenanthroline (phen) led to two new compounds, [Zn(phen)3]·2H2SIP·4H2O (1) and [Zn(phen)2(H2O)2]·2H2SIP·2H2O (2). They were characterized by element analysis, IR spectroscopy, thermalgravimetric analysis (TGA),X-ray powder diffraction (XRD), and single-crystal X-ray diffraction. Both compounds 1-2 represent the first example of Zn/phen/SIP system. The Zn (II) ion in 1 is six-coordinated by six nitrogen atoms from three phen molecules, and the H2SIP‒ ligands engage in the formation of hydrogen bond. The Zn(II) ion in 2 is coordinated by four nitrogen atoms from two phen molecules and two oxygen atoms from two water molecules. Moreover, both 1 and 2 are assembled into 3D supramolecular architectures by hydrogen bonds (O-H···O) and π-π interactions. Solvent water molecules occupying voids of the compounds serve as receptors or donors of the extensive O-H···O hydrogen bonds.

They were characterized by element analysis, IR spectroscopy, thermalgravimetric analysis (TGA), X-ray powder diffraction (XRD), and single-crystal X-ray diffraction. Both compounds 1-2 represent the first example of Zn/phen/SIP system. The Zn (II) ion in 1 is six-coordinated by six nitrogen atoms from three phen molecules, and the $H_2SIP^-$ ligands engage in the formation of hydrogen bond. The Zn(II) ion in 2 is coordinated by four nitrogen atoms from two phen molecules and two oxygen atoms from two water molecules. Moreover, both 1 and 2 are assembled into 3D supramolecular architectures by hydrogen bonds (O-H$\ldots$O) and $\pi-\pi$ interactions. Solvent water molecules occupying voids of the compounds serve as receptors or donors of the extensive O-H$\ldots$O hydrogen bonds.
