This review contains functional roles of NAC transcription factors in the transcriptional regulation of ripening in tomato fruit, describes the interplay between ABA/ethylene and NAC TFs in tomato fruit ripening. Fruit ripening is regulated by a complex network of transcription factors (TFs) and genetic regulators in response to endogenous hormones and external signals. Studying the regulation of fruit ripening has important significance for controlling fruit quality, enhancing nutritional value, improving storage conditions and extending shelf-life. Plant-specific NAC (named after no apical meristem (NAM), Arabidopsis transcription activator factor 1/2 (ATAF1/2) and Cup-shaped cotyledon (CUC2)) TFs play essential roles in plant development, ripening and stress responses. In this review, we summarize the recent progress on the regulation of NAC TFs in fruit ripening, discuss the interactions between NAC and other factors in controlling fruit development and ripening, and emphasize how NAC TFs are involved ilopment or establishment of complex ripening regulatory network models.
To analyze the epidemiologic characteristics of an outbreak of human adenovirus type 54 (HAdV-54) on Oki Island, Shimane Prefecture, Japan, in 2017 and to assess the effectiveness of a compartmentalization method in controlling the incidence and spread.
Retrospective cohort study.
The infection was diagnosed in 136 individuals, and typing was confirmed by PCR and direct sequencing. The epidemiologic characteristics of the disease including the infection rate, incubation period, and basic reproductive number (R
), ie, number of cases directly infected by an infectious patient during the course of the disease, were investigated. The effectiveness of compartmentalization for infection control was determined by simulating the outbreak using the Susceptible-Exposed-Infectious-Recovered (SEIR) model.
The majority of the HAdV-54-infected individuals were the children of 3 nursery schools (A, B, and C) and their parents on Oki Island. The infection rates in the 3 schools were 13.2%, 16.9%, and 17.2%, respectively. The one class of school B without the index case was initially compartmentalized, and the infection rate in this compartment was 0%. The incubation period was calculated to be 9.3 ± 3.5days, and the disease duration, 13.0 ± 5.4days. The R
was 1.43. Using these parameters, a SEIR model was constructed. The SEIR model well predicted the daily incidence of infection and indicated that the compartmentalization method provides effective reduction in the incidence of the infection, with much earlier control.
The compartmentalization method is effective to control HAdV-54 outbreaks.
The compartmentalization method is effective to control HAdV-54 outbreaks.Hypertension (HT) is an important risk factor for mortality and morbidity. Previous studies showed that cadmium (Cd) was associated with increased blood pressures and the prevalence of HT. This study hypothesized that Cd, regardless of its level, may increase blood pressures/HT. The objective of this study was to examine the associations between a low level of serum Cd concentration and blood pressures/HT among a general population in the Iwaki area, Japan. This was a cross-sectional study, conducted in the Aomori prefecture with 1144 volunteers aged over 19 years old, who were participants of the Iwaki health check-up in 2014. selleck chemicals llc The study assessed questionnaire survey, body composition, and serum Cd concentrations. Median serum Cd concentration was 0.06 ng/mL (interquartile range 0.05-0.08 ng/mL) among our study population. Compared to the lowest quintile of serum Cd concentration group, the highest quintile of serum Cd concentration group had 4.9 mmHg higher systolic blood pressure (SBP) (95% confidence interval [CI] 1.53-8.31, p less then 0.01) and 2.4 mmHg higher diastolic blood pressure (DBP) (95% CI 0.36-4.34, p less then 0.05), compared to the lowest quintile group. Similarly, the highest quintile of serum Cd concentration group had 1.7 times higher prevalence of HT (95% CI 1.10-2.51, p less then 0.05) than the lowest quintile group. This study identified that higher serum Cd concentration was significantly, positively, associated with SBP and DBP and HT prevalence. This study provided evidence for the associations between environmental exposure to Cd and blood pressures/HT which should be considered for future preventive measures.Aluminum exposure can mediate either acute toxicity or chronic toxicity. Aluminum exerts toxic effects on the cardiovascular system, but there are few studies on its related mechanisms. In this study, we investigated the molecular mechanism of aluminum-induced oxidative damage and apoptosis in rat cardiomyocytes. Thirty-two male Wistar rats were randomly divided into four groups, including the control group (GC), low-dose group of aluminum exposure (GL), medium-dose group (GM), and high-dose group (GH), with eight rats in each group. The GL, GM, and GH groups were given 5, 10, and 20 mg/(kg·d) of AlCl3 solution by intraperitoneal injection, and the GC group received intraperitoneal injection of the same volume of normal saline (2 ml/rat/day), 5 times a week for 28 days. At the end of the experiment, the levels of aluminum, malondialdehyde (MDA), plasma lactate dehydrogenase (LDH), creatine kinase (CK), creatine kinase isoenzyme (CKMB), and alpha-hydroxybutyrate dehydrogenase (HBDH) were measured. The pathologocytes of aluminum exposure groups was lower than that of the GC group (P less then 0.05), while the levels of Bax and caspase-3 in the cardiomyocytes of the GM and GH groups were higher than those of the GC group (P less then 0.05). The experimental results showed that aluminum could accumulate in myocardial tissues and cause damage to cardiomyocytes. It could induce oxidative stress damage by increasing the content of MDA in cardiomyocytes and trigger cardiomyocyte apoptosis by activating the pro-apoptotic proteins caspase-3 and Bax and reducing the anti-apoptotic protein Bcl-2.Boron has an important potential for facilitating biological activity and for use in pharmaceutical drug design. Boron glycine monoester (BGM) and boron glycine diester (BGD) compounds containing boron atoms were synthesized and investigated their cytotoxic, oxidative stress, and antimicrobial activities on the HepG2 cancer cell line. The cytotoxic activity of newly synthesized boron compounds on hepatocellular carcinoma was determined by the MTT method for 48 h. Antioxidant (CAT, GSH), lipid peroxidation (MDA), and enzyme activity (ACP, ALP) analyses were determined by spectrophotometric methods in HepG2 cells. Antimicrobial activity was determined by the disk diffusion method. After 48 h of BGM and BGD application to HepG2 cells, we found the IC50 values as 9.9 mM and 24 mM, respectively. While CAT and ACP enzyme activities decreased in all groups compared to the control, ALP enzyme activity did not change in the BGM group but increased in the BGD group. It was determined that the GSH level did not change in all groups, while the MDA level increased.
