The association between sleep duration, respiratory symptoms, asthma, and COPD in adults
IntroductionThe association between sleep duration and cough, wheezing, and dyspnea was unclear. This research aimed to test this relationship.MethodsResearch data were obtained from people who participated in the National Health and Nutrition Examination Survey (NHANES) from 2005 to 2012. We used weighted logistic regression analysis and fitted curves to explore the association between sleep and respiratory symptoms. In addition, we investigated the association between sleep duration, chronic obstructive pulmonary disease (COPD), and asthma. The stratified analysis is used to analyze inflection points and specific populations.ResultsThe 14,742 subjects are weighted to reflect the 45,678,491 population across the United States. Weighted logistic regression and fitted curves show a U-shaped relationship between sleep duration and cough and dyspnea. This U-shaped relationship remained in people without COPD and asthma. The stratified analysis confirmed that sleep duration before 7.5 h was negatively associated with cough (HR 0.80, 95% CI 0.73–0.87) and dyspnea (HR 0.82, 95% CI 0.77–0.88). In contrast, it was positively associated with cough and (HR 1.30, 95% CI 1.14–1.48) dyspnea (HR 1.12, 95% CI 1.00–1.26) when sleep duration was >7.5 h. In addition, short sleep duration is associated with wheezing, asthma, and COPD.ConclusionBoth long and short sleep duration are associated with cough and dyspnea. And short sleep duration is also an independent risk factor for wheezing, asthma, and COPD. This finding provides new insights into the management of respiratory symptoms and diseases
CrX (X=Se, Te) monolayers as new platform to realize robust spin filter, spin diode and spin valve
Two-dimensional ferromagnetic (FM) half-metals are promising candidates for
advanced spintronic devices with small-size and high-capacity. Motivated by
recent report on controlling synthesis of FM CrTe nanosheet, herein, to
explore the potential application in spintronics, we designed spintronic
devices based on CrX (X=Se, Te) monolayers and investigated their spin
transport properties. We found that CrTe monolayer based device shows
spin filtering and dual spin diode effect when applying bias voltage, while
CrS monolayer is an excellent platform to realize a spin valve. The
different transport properties are primarily ascribed to the semiconducting
spin channel, which is close to and away from the Fermi level in CrTe
and CrSe monolayers, respectively. Interestingly, the current in
monolayer CrSe based device also displays a negative differential
resistance effect (NDRE) and a high magnetoresistance ratio (up to 2*10).
Moreover, we found thermally induced spin filtering effect and NDRE in
CrSe junction when applying temperature gradient instead of bias
voltage. These theoretical findings highlight the potential of CrX
(X=Se, Te) monolayers in spintronic applications and put forward realistic
materials to realize nanosale spintronic device
The association between lactate dehydrogenase to serum albumin ratio and the 28-day mortality in patients with sepsis-associated acute kidney injury in intensive care: a retrospective cohort study
AbstractBackground The mortality rate of patients with sepsis-associated acute kidney injury (SA-AKI) in the intensive care unit (ICU) is high, and there is a need for early identification of SA-AKI patients with poor prognoses. This study investigated the relationship between the lactate dehydrogenase to serum albumin ratio (LAR) and prognosis in patients with SA-AKI.Methods We performed a retrospective cohort study of patients with SA-AKI who are represented in the Medical Information Mart for Intensive Care IV (MIMIC-IV). We used multivariable Cox regression analysis to determine adjusted hazard ratios (HRs) and 95% confidence intervals (CIs). Subgroup analysis, survival curves, and curve fitting were used to evaluate a connection between the LAR and prognosis in patients with SA-AKI.Results There were a total of 6453 participants in this research. The average age of the participants was 63.9 ± 16.1 years, and the average LAR was 11.0 (7.6, 17.7)/IU/g. After controlling for variables, the HRs for 28-day mortality were 1.20 (HR: 1.20, 95% CI: 1.05–1.38, p = 0.008) and 1.61 (HR: 1.61, 95% CI: 1.41–1.84, p < 0.001) for Tertile 2 (T2, 8.59≤ LAR< 14.66) and Tertile 3 (T3, LAR ≥ 14.66), respectively, compared to Tertile 1 (T1, LAR < 8.59). The outcomes for 90-day mortality and in-hospital death rate were comparable. The Kaplan–Meier (KM) analysis revealed that the group with greater LAR had higher 28-day and 90-day death rates.Conclusion Our study shows that LAR is associated with poor prognosis in patients with SA-AKI. Higher LAR is associated with higher 28-day, 90-day, and in-hospital mortality
Expression of Aspergillus niger glucose oxidase in yeast Pichia pastoris SMD1168
The aim of this study was to establish a system for high expression of Aspergillus niger glucose oxidase (GOD) with glyceraldehyde-3-phosphate dehydrogenase gene promoter (pGAP) in Pichia SMD1168. The GOD gene from A. niger accc30161 was inserted into pGAPZαA plasmid carrying a pGAP promoter and was expressed in yeast Pichia pastoris. The expression vector, pGAPZαA-GOD, was validated by colony polymerase chain reaction (PCR), agarose gel electrophoresis, restriction enzyme analysis and sequencing methods. The pGAPZαA-GOD vector was transformed into yeast P. pastoris SMD1168 by electroporation and the positive strain was validated by PCR. The expression and enzyme activity of the recombinant GOD were analysed by sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE) and enzymatic detection. The recombinant GOD in yeast was purified by ion exchange chromatography, and its biochemical properties (dynamics, thermal and pH stability) were analysed. The obtained results showed that the expression vector, pGAPZαA-GOD, was successfully constructed to express A. niger accc30161 GOD protein. After transformation, the pGAPZαA-GOD DNA fragment had been integrated into the P. pastoris SMD1168-GOD genome. High expression of GOD was achieved in SMD1168-GOD, and the enzyme activity of GOD reached 107.18 U/mL in the supernatant of the culture medium at 30 °C and pH 6. The activity of recombinant GOD protein in yeast was 1.35-fold higher than the commercial A. niger GOD, and its affinity to glucose, thermal stability and pH stability are similar to commercial GOD. Using pGAP promoter, A. niger GOD protein is efficiently expressed in recombinant P. pastoris SMD1168-GOD with defective protease.</p

Comparative Analyses of the Gut Microbiota in Growing Ragdoll Cats and Felinae Cats
Today, domestic cats are important human companion animals for their appearance and favorable personalities. During the history of their domestication, the morphological and genetic portraits of domestic cats changed significantly from their wild ancestors, and the gut microbial communities of different breeds of cats also apparently differ. In the current study, the gut microbiota of Ragdoll cats and Felinae cats were analyzed and compared. Our data indicated that the diversity and richness of the gut microbiota in the Felinae cats were much higher than in the Ragdoll cats. The taxonomic analyses revealed that the most predominant phyla of the feline gut microbiota were Firmicutes, Bacteroidota, Fusobacteriota, Proteobacteria, Actinobacteriota, Campilobacterota, and others, while the most predominant genera were Anaerococcus, Fusobacterium, Bacteroides, Escherichia-Shigella, Finegoldia, Porphyromonas, Collinsella, Lactobacillus, Ruminococcus_gnavus_group, Prevotella, and others. Different microbial communities between the Ragdoll group and the Felinae group were observed, and the compared results demonstrated that the relative abundances of beneficial microbes (such as Lactobacillus, Enterococcus, Streptococcus, Blautia, Roseburia, and so on) in the Ragdoll group were much higher than in the Felinae group. The co-occurrence network revealed that the number of nodes and links in the Felinae group was significantly higher than the Ragdoll group, which meant that the network of the Felinae group was larger and more complex than that of the Ragdoll group. PICRUSt function analyses indicated that the differences in microbial genes might influence the energy metabolism and immune functions of the host. In all, our data demonstrated that the richness and diversity of beneficial microbes in the Ragdoll group were much higher than the Felinae group. Therefore, it is possible to isolate and identify more candidate probiotics in the gut microbiota of growing Ragdoll cats
