Identification, molecular evolution, codon bias, and expansion analysis of NLP transcription factor family in foxtail millet (Setaria italica L.) and closely related crops.

The NODULE-INCEPTION-like protein (NLP) family is a plant-specific transcription factor (TF) family involved in nitrate transport and assimilation in plants, which are essential for improving plant nitrogen use efficiency. Currently, the molecular nature and evolutionary trajectory of NLP genes in the C4 model crop foxtail millet are unknown. Therefore, we performed a comprehensive analysis of NLP and molecular evolution in foxtail millet by scanning the genomes of foxtail millet and representative species of the plant kingdom. We identified seven NLP genes in the foxtail millet genome, all of which are individually and separately distributed on different chromosomes. They were not structurally identical to each other and were mainly expressed on root tissues. We unearthed two key genes (Si5G004100.1 and Si6G248300.1) with a variety of excellent characteristics. Regarding its molecular evolution, we found that NLP genes in Gramineae mainly underwent dispersed duplication, but maize NLP genes were mainly generated via WGD events. Other factors such as base mutations and natural selection have combined to promote the evolution of NLP genes. Intriguingly, the family in plants showed a gradual expansion during evolution with more duplications than losses, contrary to most gene families. In conclusion, this study advances the use of NLP genetic resources and the understanding of molecular evolution in cereals.

Discrepancies in breast cancer guideline recommendations despite similar Cochrane systematic review conclusions.

AIM: This study aims to describe the citation patterns of Cochrane systematic reviews (CSR) in guidelines for managing breast cancer. METHODS: We searched for systematic reviews on breast cancer in The Cochrane Library from the date of inception to November 15, 2023, and identified guidelines that cited them. We described how systematic reviews were cited by the guidelines in each database and each year. Additionally, we presented the relationships between the conclusions of the systematic reviews and guideline recommendations and compared the consistency of the recommendations on the same topic across different guidelines. RESULTS: A total of 64 systematic reviews and 228 guidelines were included in this study. The average number of the 64 systematic reviews cited by the guidelines was 5.91. We found that the guideline recommendations were irrelevant or inconsistent with the conclusions of the systematic reviews in 56 (38.36%) cited entries. We grouped recommendations on the same topic across different guidelines into one group, of which only 5 groups (15.15%) had completely consistent recommendations, and the other 28 groups (84.85%) had inconsistent recommendations. CONCLUSION: The average number of citations for CSR on breast cancer in the guidelines was 5.91. There were also situations in which the guideline recommendations were inconsistent with the conclusions of the included systematic reviews, and recommendations on the same topic across different guidelines were inconsistent.

Does Flavonoid Supplementation Alleviate Non-Alcoholic Fatty Liver Disease? A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

SCOPE: Higher flavonoid intake is associated with reduced risk of non-alcoholic fatty liver disease (NAFLD). However, there is a large discrepancy in the effects of flavonoid supplementation on NAFLD. To fill such knowledge gap, we systematically reviewed randomized clinical trials (RCTs) to critically assess flavonoid supplementation effect on liver function, lipid profile, inflammation, and insulin resistance in adults with NAFLD. METHODS AND RESULTS: A systematic search was conducted from 4 databases from inception until May 2023. Twelve RCTs were included in the final analysis demonstrating beneficial effects of flavonoids on ALT (SMD = -3.59, p = 0.034), AST (SMD = -4.47, p = 0.001), GGT (SMD = -8.70, p = 0.000), CK-18M30 (SMD = -0.35, p = 0.042), TG (SMD = -0.37, p = 0.001), LDL-C (SMD = -0.38, p = 0.039), TC (MD = -0.25 mmol/l, p = 0.017), steatosis score (MD = -18.97, p = 0.30), TNF-α (MD = -0.88, p = 0.000), and NF-κB (MD = -1.62, p = 0.001). CONCLUSION: This meta-analysis suggests that flavonoid alleviates NAFLD through exerting favourable effects on liver function, lipid profile, and inflammation, indicating flavonoid supplementation presents a promising drug regimen for the management of NAFLD and its associated complications.

Effect of oil exposure stages on the heat resistance of Salmonella enterica serovar Enteritidis phage type 30 in peanut flour.

The oil in low-moisture foods (LMFs) shows protective effects on bacteria during thermal processing. However, the circumstances under which this protective effect strengthens remain unclear. This study aimed to understand which step of the oil exposure to bacterial cells (inoculation, isothermal inactivation, or recovery and enumeration step) in LMFs can enhance their heat resistance. Peanut flour (PF) and defatted PF (DPF) were selected as the oil-rich and oil-free LMF models. Salmonella enterica Enteritidis Phage Type 30 (S. Enteritidis) was inoculated into four designated PF groups representing different oil exposure stages. It was isothermally treated to obtain heat resistance parameters. At a constant moisture content (aw,25°C = 0.32 ± 0.02) and controlled aw,85°C (0.32 ± 0.02), S. Enteritidis exhibited significantly high (p < 0.05) D values in oil-rich sample groups. For instance, the heat resistance values of S. Enteritidis in the PF-DPF and DPF-PF groups were D80°C of 138.22 ± 7.45 min and 101.89 ± 7.82 min; however, the D80°C in the DPF-DPF group was 34.54 ± 2.07 min. The oil addition after the thermal treatment also helped injured bacterial recovery in the enumeration. For instance, the D80°C, D85°C, and D90°C values in the DFF-DPF oil groups were 36.86 ± 2.30, 20.65 ± 1.23, and 7.91 ± 0.52 min, respectively, which were higher than those in the DPF-DPF group at 34.54 ± 2.07, 17.87 ± 0.78, and 7.10 ± 0.52 min. We confirmed that the oil protected S. Enteritidis in PF in all three stages: desiccation process, heat treatment, and recovery of bacterial cells in plates.

Does chronic consumption of orange juice improve cardiovascular risk factors in overweight and obese adults? A systematic review and meta-analysis of randomized controlled trials.

Cardiovascular diseases (CVDs) represent the leading cause of mortality worldwide. As a complex matrix of micronutrients, phytochemicals and sugars, the effects of orange juice (OJ) on CVD risk factors in overweight and obese adults warrant investigation. Hence, this systematic review and meta-analysis of randomized controlled trials (RCTs) evaluated the effect of chronic OJ consumption on the lipid profile, blood pressure, glycemic indices and inflammatory biomarkers in overweight and obese adults. Four databases were searched from inception until May 2022 and eight studies were included in the final analysis. Pooled results demonstrated the beneficial effect of OJ on systolic blood pressure (MD: -0.98 mmHg, 95% CI [-1.52, -0.44], p = 0.000, I2 = 0.0%) and HDL-C (SMD: 0.29, 95% CI [0.03, 0.54], p = 0.027, I2 = 0.0%) compared to the control group. However, total cholesterol, TG, LDL-C, glucose, insulin, HOMA-IR and CRP did not change following chronic OJ consumption. This meta-analysis demonstrates the beneficial effects of chronic OJ consumption on blood pressure and HDL-C in overweight and obese adults.

Triplication is the main evolutionary driving force of NLP transcription factor family in Chinese cabbage and related species.

The NODULE-INCEPTION-like protein (NLP) is a plant-specific transcription factor (TF) family that plays an important role in both signal transduction and nitrate assimilation. However, the NLP gene family in Chinese cabbage (Brassica rapa) has yet to be studied. Here we identified 17, 16, and 32 NLP genes in Chinese cabbage, Brassica oleracea, and Brassica napus, respectively. We found that duplication of those NLP genes almost always originated from genome-wide duplication events. Further analysis (using Arabidopsis as a reference) revealed that the NLP family in Chinese cabbage and B. oleracea was characterized by direct expansion caused by whole-genome duplication. By contrast, indirect expansion characterized B. napus, which arose from hybridization and fusion of the two species. In addition, phylogenetic and homology analyses showed that the Brassica NLP gene family has been highly conserved in evolution. Finally, we also identified optimal codons for four studied species. Altogether, through comparative genome analysis methods, we presented compelling evidence that triplication is the main driving force for the NLP TF family's evolution in Chinese cabbage and related Brassica plants, a process evidently highly conserved. This work will help in better understanding the impact of genome-wide duplication on gene families of plants.

[Meta-analysis of effects of neuromuscular electrical stimulation of lower limbs on patients with mechanical ventilation in intensive care unit].

OBJECTIVE: To evaluate the effect of lower limb neuromuscular electrical stimulation (NMES) on mechanical ventilation patients in intensive care unit (ICU). METHODS: Databases including the Cochrane Library, PubMed, Web of Science, Embase, SinoMed, CNKI, VIP and Wanfang database were searched from inception to May 2021. Randomized controlled trails (RCT) about the influence of NMES of lower limbs in patients with mechanical ventilation in ICU were collected. Routine rehabilitation measures were implemented in the control group, while the combination of routine rehabilitation and NMES on the lower limbs was implemented in the observation group. The literature screening, data extracting, and bias risk assessment of included studies were conducted independently by two reviewers. RevMan 5.3 software was used to perform Meta-analysis. Funnel plot was used to test publication bias. RESULTS: A total of 8 RCT were eventually enrolled. The literature quality evaluation results showed that 1 study was grade A and 7 studies were grade B, suggesting that the quality of the included literature was relatively high. The Meta-analysis results showed that NMES in the lower extremities could effectively shorten the duration of mechanical ventilation in ICU patients [standardized mean difference (SMD) = -0.51, 95% confidence interval (95%CI) was -0.72 to -0.31, P < 0.000 01], increase the maximum inspiratory pressure [MIP; mean difference (MD) = 14.19, 95%CI was 9.30 to 19.09, P < 0.000 01], and improve the functional status of critically ill patients [functional status score for ICU (FSS-ICU); MD = 10.44, 95%CI was 3.12 to 17.77, P = 0.005] with statistically significances. However, there were no significant advantages in increasing the Medical Research Council (MRC) score (MD = 2.13, 95%CI was -1.38 to 5.63, P = 0.23), reducing ICU mortality [relative risk (RR) = 0.80, 95%CI was 0.51 to 1.24, P = 0.31], shortening length of ICU stay (MD = -0.54, 95%CI was -3.67 to 2.59, P = 0.74), and the combined effect was not statistically significant. Funnel plot based on the duration of mechanical ventilation showed that the distribution of included articles was basically symmetrical, and no publication bias was detected. CONCLUSIONS: NMES of the lower limbs can not only shorten the ventilation duration effectively, but also improve the MIP and functional status of mechanically ventilated patients in ICU. However, it has no significant effect on the MRC score, ICU mortality and length of ICU stay of patients with mechanical ventilation. In the future, high-quality, large sample size and multi-center RCT are needed to verify the effects of NMES.

Heart failure--related mortality and hospitalization in the year following admission to a long-term care facility: the geriatric outcomes and longitudinal decline in heart failure (GOLD-HF) study.

BACKGROUND: Heart failure (HF) is common in long-term care facilities (LTCs). This study compared mortality and hospitalization rates and examined predictors of these outcomes among new LTC residents with and without HF. METHODS AND RESULTS: This prospective cohort study followed 546 newly admitted residents from 42 LTCs for up to 1 year. Health information was collected from participant and caregiver interviews, physicians' records, diagnostic procedures, and hospitalization records. Multivariate logistic regression modeling determined predictors of hospitalization among residents, and Cox proportional hazards regression determined predictors for time to mortality. HF prevalence was 21.4%. The sample was predominantly (>70%) female, and individuals with HF were significantly older with higher prevalence of reduced left ventricular ejection fraction. Overall annual mortality and hospitalization rates were 24% and 27%, respectively. Among residents with HF, 42% died and 31% were hospitalized within 1 year. Among residents with HF, use of major tranquilizers was the strongest predictor of sooner mortality; use of anticoagulants and major tranquilizers also increased mortality risk, whereas higher baseline function was associated with longer time to mortality. History of peripheral vascular disease was the strongest predictor of hospitalizations among residents with HF, and use of antiplatelet agents and history of any smoking exposure increased this risk. CONCLUSIONS: Among LTC residents, HF is associated with high mortality and hospitalization rates. Many factors contribute to mortality and hospitalizations among residents with HF, and comprehensive HF management programs are needed to improve outcomes.
