FADS1 (fatty acid desaturase 1) plays a crucial role in fatty acid metabolism, and it was recently reported to be involved in tumorigenesis. However, the role of FADS1 expression in esophageal squamous cell carcinoma (ESCC) remains unknown. In the current study, we investigated the expression and clinical pathologic and prognostic significance of FADS1 in ESCC. Immunohistochemical analyses revealed that 58.2% (146/251) of the ESCC tissues had low levels of FADS1 expression, whereas 41.8% (105/251) exhibited high levels of FADS1 expression. In positive cases, FADS1 expression was detected in the cytoplasm of cells. Correlation analyses demonstrated that FADS1 expression was significantly correlated with tumor location (p=0.025) but not with age, gender, histological grade, tumor status, nodal status or TNM staging. Furthermore, patients with tumors expressing high levels of FADS1had a longer disease-free survival time (p<0.001) and overall survival time (p <0.001). Univariate and multivariate analyses revealed that, along with nodal status, FADS1 expression was an independent and significant predictive factor (p<0.001). In conclusion, our study suggested that FADS1 might be a valuable biomarker and potential therapeutic target for ESCC.

Yifangleiju(?方?聚) is a collection of medical books that consists of 266 volumes. It is a very important set of data in studying ancient Asian medicine because it systematically organized the many medicine-related data of Eastern Asia. But it was never published again after its 30th volume was published in 1477, and only a single copy remains in Japan today. Because this book is valuable it has been republished in China based on the copy in Japan. This study is a study of the many problems that occurred in the process of republishing Yifangleiju(?方?聚) in China.

Dnd (dead end) gene encodes an RNA binding protein and is specifically expressed in primordial germ cells (PGCs) as a vertebrate-specific component of the germ plasma throughout embryogenesis. By utilizing a technique of specific nucleic acids associated with proteins (SNAAP), 13 potential target mRNAs of zebrafish Dnd (ZDnd) protein were identified from 8-cell embryo, and 8 target mRNAs have been confirmed using an RT-PCR analysis. Of the target mRNAs, the present study is focused on the regulation of geminin, which is an inhibitor of DNA replication. Using electrophoretic mobility shift assay (EMSA), we demonstrated that ZDND protein bound the 67-nucleotide region from 864 to 931 in the 3`UTR of geminin mRNA, a sequence containing 60.29% of uridine. Results from a dual-luciferase assay in HEK293 cells showed that ZDND increases the translation of geminin. Taken together, the identification of target mRNA for ZDnd will be helpful to further explore the biological function of Dnd in zebrafish germ-line development as well as in cancer cells.

<P>The installation of heterojunctions on the surfaces of carbon nanotubes (CNTs) is an effective method for promoting the charge separation processes needed for CNT-based electronics and optoelectronics applications. Conjugated polymers are proven state-of-the-art candidates for modifying the surfaces of CNTs. However, all previous attempts to incorporate conjugated polymers to CNTs resulted in unordered interfaces. Herein we show that well-defined chains of regioregular poly(3-hexylthiophene) (P3HT) were successfully grown from the surfaces of multiwalled CNTs (MWNTs) using surface-initiated Kumada catalyst-transfer polycondensation. The polymerization was found to proceed in a controlled manner as chains of tunable lengths were prepared through variation of the initial monomer-to-initiator ratio. Moreover, it was determined that large-diameter MWNTs afforded highly ordered P3HT aggregates, which exhibited a markedly bathochromically shifted optical absorption due to a high grafting density induced planarization of the polymer chains. Using ultrafast spectroscopy, the heterojunctions formed between the MWNTs and P3HT were shown to effectively overcome the binding energy of excitons, leading to photoinduced electron transfer from P3HT to MWNTs. Finally, when used as prototype devices, the individual MWNT-g-P3HT core-shell structures exhibited excellent photoresponses under a low illumination density.</P>

The equilibrium structure and electronic properties of four ultrathin free-standing pentagonal and hexagonal noble metal nanowires, that is, copper nanowires (CuNWs), silver nanowires (AgNWs), gold nanowires (AuNWs) and platinum nanowires (PtNWs), have been studied comprehensively by adopting a first-principles simulation based on the density-functional theory. The staggered topologies are more stable than the eclipsed ones by analyzing the bonding energy. The staggered ones with a linear atom chain in the center of the pentagonal or hexagons topologies are the preferred structures for CuNWs and AgNWs, but the staggered ones without a linear atom chain in the center of the pentagon or hexagon are the preferred structures for AuNWs and PtNWs due to the increasing core–core repulsions. The calculated electronic band structures and density of states present that all the noble metal nanowires are metallic. The projected densities of states (PDOS) of dominant d-states and the charge density show that the narrower d-state moved to the Fermi energy and metallic bonding character for all the noble metal nanowires.

Aims: Postoperative morbidity following hepatectomy remains high, and understanding its risk factors is important to improve perioperative outcomes. We aimed to identify the role of two non-invasive markers - albumin-bilirubin (ALBI) and aspartate transaminase to platelet ratio index (APRI) - in predicting postoperative morbidity following hepatectomy for hepatocellular carcinoma (HCC). Methods: A multicenter data of patients undergoing hepatectomy for HCC at 8 centers were retrospectively analyzed. These patients were divided into normal and high groups according to preoperative ALBI and APRI scores. ALBI and APRI’s predictive accuracy of postoperative 30-day overall and major morbidity were evaluated by the area under the receiver operating characteristic curve (AUC) and compared with two conventional scores: Child-Pugh grade and model for end-stage liver disease (MELD). Results: In 2,301 patients, 866 (37.6%) and 400 (17.4%) were in the high ALBI and APRI groups, respectively. There were significant differences of postoperative overall morbidity between the normal and high ALBI groups (26.2% vs. 40.1%, P<0.001), as well as between the normal and high APRI groups (29.2% vs. 42.4%, P<0.001). The AUCs of the ALBI and APRI scores for predicting overall morbidity are greater than those of Child- Pugh grade and MELD score. Multivariable analyses revealed that ALBI and APRI were independent predictors of overall morbidity in both preoperative and postoperative prediction models. Similar results existed in predicting postoperative major morbidity. Conclusions: Preoperative ALBI and APRI could predict postoperative 30-day overall and major morbidity following hepatectomy for HCC before or after surgery.

Semi-dwarfism is an agronomically important trait in breeding for resistance to damage by wind and rain (lodging resistance)and for stable high yields. Dwarf Polish wheat (Triticum polonicum L., 2n = 4x = 28, AABB AS304) is a potential donor of dwarfing and other traits for common wheat improvement. A genetic analysis using an F2 population derived from a cross of AS304 and tall cultivar AS302 and derived F2:3 lines indicated that AS304 carries a recessive dwarfing gene, temporarily designated Rht-dp. Molecular markers and bulked segregant analysis were used to characterize and map the gene. Eight polymorphic SSR markers (Xwmc511, Xgwm495, Xgwm 113, Xgwm192, Xgpw7026, Xgpw3017, Xgpw1108 and Xgpw7521) on chromosome arm 4BS and two AFLP markers (M8/E5 and M4/E3) were mapped relative to the dwarfing locus. The closest linked markers, Xgpw3017 and M8/E5 at 0.5 and 3.5 cM, respectively, from Rht-dp will enable its marker assisted transfer to wheat breeding populations. Allelic tests indicated that Rht-dp was allelic to Rht-B1b; hence it may be an alternative allele at the Rht-B1 locus.
