    Abstract Three new zinc(II) and one vanadium(V) complexes, [Zn2Cl2L2] (1), [Zn2I2L2] (2), [ZnCl2(HL)] (3), and [V2O2(μ-O)2L2] (4), where L is 5-bromo-2-((2-(methylamino)ethylimino)methyl)phenolate, have been synthesized and characterized by elemental analyses, IR and UV-Vis spectra, as well as molar conductivity. Structures of the complexes were confirmed by single crystal X-ray diffraction. Complexes 1 and 2 are isostructural dinuclear zinc compounds, with the Zn atoms in square pyramidal coordination. The Zn atoms in the mononuclear complex 3 are in tetrahedral coordination. Complex 4 is a dinuclear vanadium(V) compound, with the V atoms in octahedral coordination. The complexes were assayed for antibacterial activities by MTT method.

    Abstract Two new and similar cobalt(III) complexes, [CoL2]·NO3 (1) and [CoL2]·Cl (2), where L is 5-bromo-2-((2-(phenylamino)ethylimino)methyl)phenolate, have been synthesized and characterized by IR and UV-Vis spectra. Structures of the complexes were confirmed by single crystal X-ray determination. The Co atoms in the complexes are in octahedral coordination, with the donor atoms come from the two Schiff base ligands, viz. phenolate oxygen, and imino and amino nitrogen. The anions of the cobalt salts crystallized as counteranions in the complexes. The complexes were assayed for antibacterial activities by MTT method.

    Abstract Background: The level of vitamin D in pregnant women and the effect of vitamin D supplementation are lack in Taiwan.
    Objective: To investigate the vitamin D serum level and the effect of its supplementation on pregnancy.
    Methods: We included 1048 pregnant women who underwent prenatal exam with known serum 25-hydroxyvitamin D3 [25(OH)D3] levels and delivery at the Mackay Memorial Hospital, Taipei, Taiwan during 2015-2018. A daily dose 2000 IU of vitamin D was given, starting at 12-16 weeks of pregnancy, to reach the level of 20 ng/mL, and then a maintenance dose of 800 IU/day was given. The other 3654 women without vitamin D supplementation delivered in 2018 served as control group. Pregnancy outcomes were recorded for analysis.
    Results: Over 80% of the 1048 pregnant women were vitamin D deficiency. There was an inverse correlation between serum vitamin D levels and maternal body mass index (p = 0.0366). We compared 375 women with serum vitamin D levels increased above 30 ng/mL after supplementation with control group. The rates of preterm birth, low birth weight, and postpartum hemorrhage between these 2 groups were 6.67% vs. 11.19% (p = 0.007), 6.40% vs. 10.0% (p = 0.025), and 1.33% vs. 3.20% (p = 0.04), respectively.
    Conclusion: Vitamin D deficiency is very prevalent in pregnant women, especially those with high BMI, in Taiwan. It can be corrected by adequate vitamin D supplementation, which may decrease the risk of pregnancy complications and bring benefits to the fetus.

    Abstract Digital transformation plays an important role in improving the efficiency of production of enterprises and can provide strong support for green and sustainable development. Compared with domestic enterprises, outward foreign direct investment (OFDI) enterprises have greater access to advanced digital technology. This paper aims to analyze the path selection of green and sustainable production for the digital transformation of manufacturing outward foreign direct investment (OFDI) companies, whether gradual or leapfrogging. However, there is a lack of systemic game mechanisms and numerical simulation methods for heterogeneous enterprises. Based on the analysis of reverse technology spillover intensity of outward foreign direct investment (OFDI) and differences in the absorptive capacity of enterprises, we have proposed the evolutionary game model for different path selection of digital transformation of manufacturing enterprises, due to heterogeneous enterprises under different spillover degrees with numerical analysis methods. The research results show that: (i) Under low reverse technology spillover intensity, all enterprises evolve to a gradual transformation path, and enterprises with weaker absorptive capacity converge faster; (ii) There is a certain threshold for reverse technology spillover. When reverse technology spillover intensity exceeds the threshold, enterprises with stronger absorptive capacity converge to a leapfrog transformation path, but enterprises with weak absorptive capacity converge to a gradual transformation path; (iii) With high reverse technology spillover intensity, all enterprises evolve toward a leapfrog transformation path, and faster convergence happens to enterprises with higher absorptive capacity. The evolutionary game path of digital transformation in manufacturing enterprises is illustrated in Fig. 1.

    Abstract Hard x-rays are widely used for plasma diagnosis, nondestructive inspection, and high-resolution x-ray imaging. A typical x-ray source is a tabletop micro-focus x-ray source. Here, a bifocal photon sieve (PS) with the smallest diameter of 59.6 nm was designed and fabricated by electron-beam lithography to focus hard x-rays on variable-resolution array images. An imaging experiment at 8.39 keV demonstrates that the designed and fabricated PS has two different focal lengths. The numerous pinholes that can be optimized provide richer degrees of freedom to realize considerably more functionalities. A multi-focal PS provides the possibility of splitting x-rays and further extends interferometry from visible light to hard x-rays.

    Abstract Background: The association between sepsis and non-infectious respiratory diseases is well-documented, yet the specific causal link between the two remains unclear. In order to explore this relationship further, we employed a Mendelian randomization (MR) analysis utilizing data from the UK Biobank and FinnGen Biobank.
    Methods: We analyzed the summary statistics of a genome-wide association study (GWAS) summary statistics for chronic obstructive pulmonary disease (COPD), asthma, pulmonary embolism (PE), idiopathic pulmonary fibrosis (IPF), obstructive sleep apnea (OSA), lung cancer, sepsis, and sepsis-related mortality. We employed the inverse-variance weighted (IVW) method and four additional MR methods. Heterogeneity and horizontal pleiotropy were assessed using the Cochrane's Q test, MR-Egger intercept, and MR-PRESSO test. A sensitivity analysis was also performed.
    Results: MR analysis showed associations between COPD and lung cancer with increased sepsis risk (odds ratio (OR)IVW 1.138, P = 0.006; (OR)IVW 1.123, P = 0.031; respectively) and sepsis mortality ((OR)IVW 1.350, P = 0.022; (OR)IVW 1.312, P = 0.022; respectively). Asthma exhibited a potential protective effect against sepsis mortality((OR)IVW = 0.300, P = 0.039), while PE demonstrated a risk effect ((OR)IVW = 1.148, P = 0.032). No causal association was observed between asthma, PE, and sepsis (P > 0.05). IPF and OSA were not significantly associated with sepsis or sepsis-related mortality (P > 0.05). Heterogeneity and horizontal pleiotropy were not evident for asthma or lung cancer (P > 0.05). However, horizontal pleiotropy was suggested for COPD by the MR-Egger regression (P < 0.05), but not by the MR-PRESSO test (P > 0.05). IPF and OSA were not significantly associated with sepsis or sepsis-related mortality (P > 0.05).
    Conclusions: Our MR analysis offers new insights into potential links between noninfectious respiratory diseases and the risk of sepsis. However, additional investigation into the underlying mechanisms and clinical studies are necessary to confirm these findings.

    Abstract Plants fully depend on their immune systems to defend against pathogens. Upon pathogen attack, plants not only activate immune responses at the infection site but also trigger a defense mechanism known as systemic acquired resistance (SAR) in distal systemic tissues to prevent subsequent infections by a broad-spectrum of pathogens. SAR is induced by mobile signals produced at the infection site. Accumulating evidence suggests that reactive oxygen species (ROS) play a central role in SAR signaling. ROS burst at the infection site is one of the earliest cellular responses following pathogen infection and can spread to systemic tissues through membrane-associated NADPH oxidase-dependent relay-production of ROS. It is well known that ROS ignite redox signaling and when in excess, cause oxidative stress damaging cellular components. In this review, we summarize current knowledge on redox regulation of several SAR signaling components. We discuss the ROS amplification loop in systemic tissues involving multiple SAR mobile signals. Moreover, we highlight the essential role of oxidative stress in generating SAR signals including azelaic acid and extracellular NAD(P) [eNAD(P)]. Finally, we propose that eNAD(P) is a damage-associated molecular pattern serving as a converging point of SAR mobile signals in systemic tissues.
