Abstract	Herein, the direct morphological evidence of the extension-induced phase-separated structures in the electrospinning jet observed by high-speed video imaging and by light scattering technique is reported. Model solutions of poly(vinyl alcohol) (PVA)/water are electrospun. Two types of internal structures, that is, long strings and short ellipsoids, are found. A light scattering model is derived for the V

Abstract	Background: Few studies have simultaneously compared the predictive value of various frailty assessment tools for outcome measures in patients undergoing gastrointestinal cancer surgery. Therefore, it is difficult to determine which assessment tool is most relevant to the prognosis of this population. Aim: To investigate the predictive value of three frailty assessment tools for patient prognosis in patients undergoing gastrointestinal cancer surgery. Methods: This single-centre, observational, prospective cohort study was conducted at the Affiliated Lianyungang Hospital of Xuzhou Medical University from August 2021 to July 2022. A total of 229 patients aged ≥ 18 years who underwent surgery for gastrointestinal cancer were included in this study. We collected baseline data on the participants and administered three scales to assess frailty: The comprehensive geriatric assessment (CGA), Fried phenotype and FRAIL scale. The outcome measures were the postoperative severe complications and increased hospital costs. Results: The prevalence of frailty when assessed with the CGA was 65.9%, 47.6% when assessed with the Fried phenotype, and 34.9% when assessed with the FRAIL scale. Using the CGA as a reference, kappa coefficients were 0.398 for the Fried phenotype and 0.291 for the FRAIL scale (both Conclusion: The CGA was an independent predictor of increased hospital costs in patients undergoing surgery for gastrointestinal cancer.

Article: 1,3-Thiazole on Cu(100) and O/Cu(100): Adsorption and Reaction Pathways

Abstract	1,3-Thiazole is found to be nearly perpendicularly adsorbed on Cu(100), with the N atom attaching to an atop site and an adsorption energy of ∼19.5 kcal·mol–¹. The N–C–S moiety of the adsorbed 1,3-thiazole has a larger change in bond length as compared to a free 1,3-thiazole molecule. The adsorbed 1,3-thiazole can decompose below 200 K, forming atomic S and −CHCHNCH–. A small amount of R–S– (R: CHCHNCH) is detected on the surface at 200 K. Complete desulfurization of the 1,3-thiazole occurs at 400 K. Further reaction of the −CHCHNCH– produces H₂ and HCN at higher temperatures. In the presence of adsorbed oxygen atoms(O/Cu(100)), new disulfide intermediates (R–S–S–R, R: CHCHNCH) from the thiazole reaction are measured at 300 K and can further decompose into atomic S and −CHCHNCH– at 400 K. In addition, other surface species of −NCO and >C═C═O are also observed at 500 K. These species eventually react to generate H₂O, CO, CO₂, and N₂. Further calculations indicate that the S–CHN bond of 1,3-thiazole would break preferentially, as compared to the S–CHCH bond, in the decomposition process on Cu(100).

Abstract	Adsorption and reactions of 3-bromopyridine and 2-bromopyridine on Cu(100) and O/Cu(100) have been investigated, attempting to explore the chemical processes by identifying a variety of possible reaction intermediates and products, such as bipyridine, pyridyne, pyridine, pyridine oxide, hydroxypyridine, pyridone, and so forth. They can be generated from the Ullmann reaction, dehydrogenation, hydrogenation, hydroxylation, and oxidation of pyridyl groups on the surfaces. Temperature-programmed reaction/desorption, reflection–absorption infrared spectroscopy, X-ray photoelectron spectroscopy, and density functional theory calculations have been employed for this research. At a monolayer coverage of 3-bromopyridine on Cu(100), a perpendicular 3-pyridyl is generated on the surface below 300 K because of the C–Br bond scission. This surface species undergoes loss of hydrogen, hydrogenation, and ring rupture at ∼450 K. The first two processes result in the pyridine formation. The dissociated fragments continue to react to form H2, HCN, and (CN)2 at higher temperatures. The relative amounts of the products of pyridine, H2, HCN, and (CN)2 are dependent on the coverage of 3-pyridyl. In the presence of surface oxygen atoms (O(ad)), dissociation of 3-bromopyridine also generates 3-pyridyl first. However, the pyridine formation from this intermediate is terminated, with decreased H2, HCN, and (CN)2. Additional products of H2O, CO, CO2, and HNCO are generated. For 2-bromopyridine (1.0 L) on Cu(100), at a coverage slightly higher than a monolayer, a perpendicular 2-pyridyl is generated below 300 K, and its decomposition generates pyridine (∼525 K), together with H2, HCN, and (CN)2 at higher temperatures. At a large exposure of 10.0 L of 2-bromopyridine, additional pyridine is generated at 650 K, which is suggested to be originated from an electronically/structurally strongly perturbed C5NH4 intermediate. On O/Cu(100), no 2-pyridyl intermediate is measured from the primary 2-bromopyridine decomposition; however, 2-oxypyridine is formed instead. This intermediate can be produced from nucleophilic attack on the 2C atom of 2-bromopyridine by O(ad) and/or from recombination of 2-pyridyl and O(ad). The 2-oxypyridine further reacts to form H2O, HCN, CO, CO2, HCNO, and (CN)2.

Abstract	Objective: Previous reports of the annual incidence of type 1 diabetes (T1D) in China were conducted using retrospective hospital cases, which may not reflect the reality. This longitudinal study estimated T1D incidence in a Chinese population of 21.7 million from 2007 to 2017. Research design and methods: A population-based registry of T1D was performed by the Beijing Municipal Health Commission Information Center. Annual incidence and 95% CIs were calculated by age group and sex. The association of sex with T1D incidence and predicted new cases of T1D were assessed using Poisson regression models. Annual percentage change and average annual percentage of change were assessed using Joinpoint regression. Results: Overall, there were 6,875 individuals who developed T1D from 2007 to 2017 in this population. T1D incidence (/100,000 persons) (95% CI) significantly increased from 2.72 (2.51, 2.93) in 2007 to 3.60 (3.38, 3.78) in 2017 ( Conclusions: T1D incidence in this large Chinese population is higher than has been reported previously. From 2007 to 2017, although the incidence peak was in the 10-14-year age group, the T1D incidence increased sharply in adults but not in youth.

Abstract	Background: Apurinic/apyrimidinic (abasic/AP) sites are among the most common endogenous DNA lesions. AP sites, if not repaired, could result in genomic instability as well as chromosome aberrations. Information regarding the direct assay of the number of abasic sites in human leukocytes and its association with risk of breast cancer has not been reported. Methods: In this study, we investigated the association between certain risk factors for breast cancer and the background levels of AP sites in leukocytes derived from 148 Taiwanese women with breast cancer and 140 cancer-free controls. The risk factors studied include age, body mass index (BMI), and polymorphisms of apurinic/apyrimidinic endonuclease (APE1) [APE1 Asp148Glu(rs3136820)]. Results: Mean levels of AP sites were estimated to be 23.3 and 50.3 per 10 Conclusions: We confirmed that cumulative body burden of AP sites is a significant predictor of the risk of developing breast cancer and that genetic predisposition and environment factors may modulate the induction of oxidative DNA lesions in breast cancer patients.

Abstract	A facile and economic modification of polyvinylidene fluoride (PVDF) with an orientation of diamine is presented herein. The physical characterizations of native and diamine-grafted PVDF membranes are analyzed by three different techniques: the ninhydrin test, Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM). The diamine-grafted PVDF is activated by glutaraldehyde for enzyme immobilization. The response surface methodology (RSM) is used to search the optimal immobilization conditions and to understand the significance of the factors affecting the responses of immobilized lipase. The optimal conditions for lipase immobilization are: a reaction time of 90 min, temperature of 35 Â°C, pH of 6, and an enzyme concentration of 7 mg/mL. An experiment performed under the optimum conditions obtains lipase activity of 60 U per g of membrane. A good agreement between the calculated and experimental values is thereby achieved.
