Spatial and temporal resource allocations within inflorescences have been well-studied in many plants based on flowering sequence or floral position. However, there had been few attempts to investigate architectural effects and resource competition in species where the blooming pattern does not follow a linear positional pattern within the inflorescence. Moreover, most flowering plants show female-biased sex allocation in early or basal flowers, but it is unclear in species with inherent and changeless ovule production.

We investigated intra-inflorescence variation in reproductive traits of Salvia przewalskii, a perennial herb with 4-ouvle ovary flowers and flowering sequence-floral position decoupled inflorescences. To detect the effects of resource competition and architectural effects on reproductive success, we manipulated inflorescence (removed floral buds by position and flowering sequence) and pollination (opened and supplemented pollination).

Pollen production and dry mass deceased from bottom to top flowers but did not significantly differ following flowering sequence, resulting in male-biased sex allocation in basal flowers. The seed production, fruit set, and bud development exhibited significant declining trends from proximal to distal positions regardless of the thinning and pollen treatments. Meanwhile, the seed production, fruit set, and bud development success did not significant differ when thinning was conducted according to flowering sequence.

Architectural effects plays a crucial role in resource allocation within decoupled flowering inflorescences. Moreover, our results highlighted that inherent floral traits such as changeless ovule production, may modify architectural effects on sex allocation.

In this study, dextran sodium sulfate (DSS)-induced colitis mice were used to study the protective effects of polyphenolic extracts of coffee cherry husks (CCHP) on inflammation. The results indicated that CCHP administration alleviated the histological changes of DSS-induced colitis in mice and downregulated the mRNA level of TNF-α, IL-1β, IL-6 and Cox-2. Interestingly, CCHP inhibited the activation of microglia and suppressed neural inflammation in the brain. The TLR4/Myd88/NF-κB signaling pathway was examined and found to be inhibited by CCHP. Furthermore, a determination of the gut microbiota showed that an alteration of microbiota induced by DSS was restored by CCHP, including the decrease of the relative abundance of Proteobacteria and the increase of Bacteroidota. In conclusion, our results revealed the great potential of CCHP to alleviate brain inflammation in colitis mice by inhibiting the NF-κB signaling pathway and regulating gut microbiota.

The purpose of this article is to report a case of ocular gnathostomiasis presenting with acute anterior uveitis and uveitis glaucoma.

At present, no clinically effective method is available for the treatment of IUAs. With its advantages of being individualized and precise, three-dimensional (3D) bioprinting technology has been used to regenerate various damaged tissues and organs. Granulate colony-stimulating factor (G-CSF) clearly plays a positive role in endometrial regeneration, but precise and individualized drug applications are a prerequisite for improving the therapeutic effect of G-CSF. This study utilized a 3D-printed hydrogel in combination with a sustained-release microsphere (SRM) system to prepare a 3D-printed G-CSF-SRM system (3D microsphere) in vitro. The system advantageously allowed the spatial control of drug distribution and structural individualization. In addition to being long-acting and having a sustained release, the 3D microspheres increased the local concentration of G-CSF. Using a Sprague-Dawley rat IUA model, we confirmed that the 3D microspheres promoted local endometrial regeneration, significantly suppressed endometrium tissue fibrosis, and improved endometrial cell (epithelial and stromal cell) and vascular regeneration. The 3D microspheres significantly improved the endometrial receptivity and restored the pregnancy function of the damaged endometrium. We believe that the 3D-printed G-CSF-SRM hydrogel scaffold design concept may be used to develop a more precise and individualized treatment method for the structural and functional repair of damaged endometrial tissues.To provide a comparative meta-analysis and systematic review of the risk and clinical outcomes of coronavirus 2019 (COVID-19) infection between fully vaccinated and unvaccinated groups. Eighteen studies of COVID-19 infections in fully vaccinated ("breakthrough infections") and unvaccinated individuals were reviewed from Medline/PubMed, Scopus, Embase, and Web of Science databases. The meta-analysis examined the summary effects and between-study heterogeneity regarding differences in the risk of infection, hospitalization, treatments, and mortality between vaccinated and unvaccinated individuals. he overall risk of infection was lower for the fully vaccinated compared to that of the unvaccinated (relative risk [RR] 0.20, 95% confidence interval [CI] 0.19-0.21), especially for variants other than Delta (Delta RR 0.29, 95% CI 0.13-0.65; other variants RR 0.06, 95% CI 0.04-0.08). The risk of asymptomatic infection was not statistically significantly different between fully vaccinated and unvaccinated (RR 0.56, 95% CI 0.27-1.19). There were neither statistically significant differences in risk of hospitalization (RR 1.06, 95% CI 0.38-2.93), invasive mechanical ventilation (RR 1.65, 95% CI 0.90-3.06), or mortality (RR 1.19, 95% CI 0.79-1.78). Conversely, the risk of supplemental oxygen during hospitalization was significantly higher for the unvaccinated (RR 1.40, 95% CI 1.08-1.82). Unvaccinated people were more vulnerable to COVID-19 infection than fully vaccinated for all variants. Once infected, there were no statistically significant differences in the risk of hospitalization, invasive mechanical ventilation, or mortality. Still, unvaccinated showed an increased need for oxygen supplementation. Further prospective analysis, including patients' risk factors, COVID-19 variants, and the utilized treatment strategies, would be warranted.The discrete inverted-Keggin ion [Mo12O32(OH)2(4-N3C2H2-C6H4AsO3)4]2- (1) has been prepared in an aqueous acidic (pH 0.8) medium by the reaction of MoO3 with the (4-triazolylphenyl)arsonic acid 4-N3C2H2-C6H4AsO3H2 under hydrothermal conditions and was isolated as a sodium salt in 21% yield. The exact same reaction in the presence of Cu2+ ions resulted in the neutral metal-organic framework (MOF) Cu2[Mo12O34(4-N3C2H2-C6H4AsO3)4] (Cu-1) in 68% yield. The inverted-Keggin ion 1 comprises a metal-oxo core, which is capped by four organoarsonate groups, and in Cu-1, individual polyanions are linked in the solid state by coordination of the Cu2+ ions with the triazolyl groups. The discrete ion 1 was characterized by single-crystal X-ray diffraction (XRD), Fourier transform infrared (FT-IR), and atomic absorption (AA) spectroscopy, as well as thermogravimetric analysis (TGA), and the POM-MOF Cu-1 was characterized by single-crystal and powder XRD, FT-IR, TGA, and gas sorption. Cu-1 has channels with a diameter of around ∼0.9 nm and exhibits a water-vapor adsorption capacity of 89.7 cm3 g-1 (p/p0 = 0.95).The present study aimed to investigate the effects of saturated fatty acids (SFA) and n-6 polyunsaturated fatty acids (PUFA) on alcoholic liver disease (ALD) and the underlying mechanisms. C57BL/6J male mice were randomly fed a corn oil or palm oil diet (rich in n-6 PUFA and SFA, respectively) with or without ethanol for four weeks (n = 10/group). A series of experiments in vitro with AML-12 hepatocyte were conducted to better elucidate the potential mechanisms underlying the phenomenon observed in animals. Compared with palm oil, corn oil aggravated alcohol-induced liver injury and hepatic steatosis, indicated by a histological analysis and significant elevations of plasma alanine aminotransferase and hepatic triacylglycerol (TG) level. Apoptosis-associated proteins in the ASK1-JNK pathway were significantly enhanced in the liver of mice from the corn oil + ethanol group than in the palm oil + ethanol group. The corn oil + ethanol diet also inhibited the activation of both AMPK and downstream protein acetyl-CoA carboxylase (ACC) and promoted the SREBP-1c expression, subsequently accelerating lipid synthesis. In addition, 4-hydroxynonenal (4-HNE) levels in plasma and liver were significantly upregulated in response to corn oil + ethanol feeding. Interestingly, the in vitro study showed that 4-HNE significantly attenuated cell viability, elevated the expression of cleaved-caspase 3 protein and TG level, and regulated key molecules in ASK1-JNK and AMPK pathways in a dose-dependent manner. In conclusion, the n-6 PUFA diet showed a negative effect on alcohol-induced liver injury and steatosis. It might be related to the upregulation of 4-HNE and subsequent changes of proteins, namely, ASK1, JNK, AMPK, ACC, and SREBP-1c.Dietary ω-3 PUFAs are highly prone to oxidation, and this may potentially limit their application in the health-promoting field. Here, we sought to investigate whether and how oxidized PUFAs modulate the susceptibility of mice to Salmonella typhimurium (S. Tm) infection. Algae oil (AO) and oxidized algae oil (ox-AO) were administered to the C57BL/6 mice prior to S. Tm infection. Compared to the S. Tm group, ox-AO increased bacterial burden in systemic and intestinal tissues, downregulated host anti-infection responses, and developed worse colitis. In macrophages, ox-AO decreased both phagocytosis of S. Tm and clearance of intracellular bacteria and dampened the activation of mitogen-activated protein kinase (MAPK), NF-κB, and autophagy pathways. Furthermore, ox-AO diminished LPS-induced inflammatory cytokine production and S. Tm induced NLRC4 inflammasome activation. This study reveals that oxidized PUFAs may contribute to the development of enteric infections and regular monitoring of the oxidation status in commercial PUFA supplements to prevent their potential adverse impact on human health.
