RESUMO

Stem growth habit is a key plant architecture trait determining yield potential in grain legumes, and the phenotypic change from the indeterminate stem growth habit of wild mungbeans (Vigna radiata) to the determinate stem growth habit of cultivated mungbeans is a critical domestication transition. Here we show that indeterminate stem growth in wild mungbean is modulated by a single gene, VrDet1, which encodes a signaling protein of shoot apical meristems. The transition from an indeterminate to a determinate stem growth habit was achieved by selection of two linked point mutations in two putative cis-regulatory elements, resulting in a significant reduction in gene expression. Both the wild-type nucleotides corresponding to the two point mutations were essential for VrDet1 function. In addition, two highly diverse haplotypes of Vrdet1 were found in cultivated mungbeans, suggesting dual domestication of Vrdet1. VrDet1 was orthologous to Dt1 in wild soybean and PvTFL1y in wild common bean, where multiple loss-of-function mutations altering the coding sequences of individual genes were selected to produce determinate stems in cultivated accessions. Interspecific comparison of these orthologs in the wild and cultivated accessions reveals the most conservative interspecific and intraspecific parallel domestication events with the broadest mutational spectrum of a domestication trait in leguminous crops. We also found that interspecifically and functionally conserved promoters possess cis-regulatory elements that are highly conserved in kind but greatly variable in number and order, demonstrating the evolutionary dynamics of regulatory sequences. This work provides insights into the origins of cultivated mungbean and exemplifies the conservativeness and plasticity of the domestication processes of related crops.

RESUMO

BACKGROUND: Phosphatidyl ethanolamine-binding proteins (PEBPs) are involved in the regulation of plant architecture and flowering time. The functions of PEBP genes have been studied in many plant species. However, little is known about the characteristics and expression profiles of PEBP genes in wild peanut species, Arachis duranensis and Arachis ipaensis, the diploid ancestors of cultivated peanuts. RESULTS: In this study, genome-wide identification methods were used to identify and characterize a total of 32 peanut PEBP genes, 16 from each of the two wild peanut species, A. duranensis and A. ipaensis. These PEBP genes were classified into 3 groups (TERMINAL FLOWER1-like, FLOWERING LOCUS T-like, and MOTHER OF FT AND TFL1-like) based on their phylogenetic relationships. The gene structures, motifs, and chromosomal locations for each of these PEBPs were analyzed. In addition, 4 interchromosomal duplications and 1 tandem duplication were identified in A. duranensis, and 2 interchromosomal paralogs and 1 tandem paralog were identified in A. ipaensis. Ninety-five different cis-acting elements were identified in the PEBP gene promoter regions and most genes had different numbers and types of cis-elements. As a result, the transcription patterns of these PEBP genes varied in different tissues and under long day and short day conditions during different growth phases, indicating the functional diversities of PEBPs in different tissues and their potential functions in plant photoperiod dependent developmental pathways. Moreover, our analysis revealed that AraduF950M/AraduWY2NX in A. duranensis, and Araip344D4/Araip4V81G in A. ipaensis are good candidates for regulating plant architecture, and that Aradu80YRY, AraduYY72S, and AraduEHZ9Y in A. duranensis and AraipVEP8T in A. ipaensis may be key factors regulating flowering time. CONCLUSION: Sixteen PEBP genes were identified and characterized from each of the two diploid wild peanut genomes, A. duranensis and A. ipaensis. Genetic characterization and spatio-temporal expression analysis support their importance in plant growth and development. These findings further our understanding of PEBP gene functions in plant species.

RESUMO

BACKGROUND: Victims exposed to serious traumatic experiences may develop post-traumatic stress disorder (PTSD) and suffer this mental health problem for a long time. Different types of trauma displayed a chronicity rate of PTSD within the range of 6.3-68.9 %. As one of the most common and severe natural disasters, the natural progression of flood related PTSD has not been revealed. The aim of this study was to estimate the chronicity rate and identify the prognostic factors of PTSD in flood victims. METHODS: Flood victims, who were over the age of 16 and diagnosed with PTSD in 2000 in Huarong, Ziyang, and Anxiang counties of Hunan province, China, were enrolled in this survey. Current probable PTSD was analyzed using the PTSD Checklist-Civilian version. Data were collected in face-to-face interviews and analyzed using univariate analysis and multiple logistic regression models. RESULTS: The rate of current probable PTSD was 15.4 %. The current occurrences of re-experiencing, avoidance/numbing, and hyper-arousal symptom groups were 69.3 %, 17.2 %, and 50.2 %, respectively. Significant prognostic factors for current probable PTSD were flood-related stressors (e.g., life-threatening experiences, extreme physical adversity, and extreme psychological adversity) and frequency of general collective action. The relationships still existed when taking the fluctuation of frequency of general collective action into consideration. Gender and education level showed no influence on the recovery from PTSD. The impact of age in this study was inconsistent; in the 2000 model, around 2006 model, around 2013 model, and all FGCA model, older age was positive prognosis factor for PTSD; in the univariate analysis and fluctuation model, age showed no influence on the recovery from PTSD. CONCLUSIONS: Our findings indicated that PTSD can persist 13 years after a flood. Demographic characteristics (e.g., age, gender, and education level) seem to have no influence on the recovery from PTSD. Trauma-related stressors and social participation are important predictors for remission from chronic PTSD.

RESUMO

Aptamers against inactive Vibrio alginolyticus were selected from an 82-nt ssDNA random library by systematic evolution of ligands by exponential enrichment. After 15 rounds of selection, the final pool of aptamers was highly specific for inactivated V. alginolyticus and had a dissociation constant of 27.5 ± 9.2 nM. Using these aptamers and PCR, V. alginolyticus could be detected at 100 cells/ml. Sequencing of the final pool of aptamers revealed that some sequences, termed high-frequency aptamers, appeared more than once; these may be of practical application. All sequences obtained were divided into nine families according to their homology tree, some conserved sequences were also found in each of the six families. One sequence was found in significant proportions of the aptamers, suggesting that this conserved sequence might be important for forming the three-dimensional aptamer structure.

RESUMO

BACKGROUND: Constructing tissue-engineered kidneys using decellularized kidney scaffolds (DKS) has attracted widespread attention as it is expected to be the key to solving the shortage of donor kidneys. However, thrombosis and the host inflammatory response are unfavorable factors that hider the re-endothelialization and vascularization of the decellularized scaffolds. METHODS: Heparin was immobilized into the DKS using the method of 1-ethyl-3-(3-dimethylaminopropyl)-carbodiimide/N-hydroxysuccinimide (EDC/NHS) activation. Fourier-transform infrared (FTIR) spectra were used to verify the heparinization of DKS. Human umbilical vein endothelial cells (HUVECs) were seeded and cultured in the DKS, then the sliced scaffolds were transplanted subcutaneously into nude mouse. Scanning electron microscopy and a series of histochemical stains including hematoxylin and eosin (H&E), elastic Verhöeff-Van Gieson (EVG), Sirius red, Masson's trichrome, and toluidine blue (TB) staining were used for morphological characterization. The qRT-PCR analysis, immunohistochemistry (IHC), and immunofluorescence (IF) staining were used to determine the expression of related molecular markers. RESULTS: The rat DKS completely retained the extracellular matrix and heparinized modification. The H&E staining results showed there were more HUVECs covering the internal surfaces of tubular structures in the HEP-DKS group compared with the DKS group. The IF analysis results revealed that CD31, Ki67, and CD206 had higher positive rates in HUVECs in the HEP-DKS group compared to the DKS group. Both groups of scaffolds showed blood vessel formation via H&E staining, and there were more blood vessels in the HEP-DKS group compared with the native DKS group (P<0.05). The qRT-PCR results showed that the levels of IL-1ß, IL-6, and TNF-α in the HEP-DKS group were significantly lower than those of the native DKS group, while the expression level of IL-10 was significantly higher than that in the native DKS group (P<0.05). CONCLUSIONS: Heparin modification improves the re-endothelialization and vascular regeneration of the DKS through anticoagulation in vitro and in vivo. The anti-inflammatory effect of heparin on the transplanted host was initially confirmed, and it is considered that this effect may play a non-negligible role in promoting DKS re-endothelialization and angiogenesis. Heparinized DKS is therefore a promising candidate for kidney tissue engineering.

RESUMO

OBJECTIVE: To investigate the infection of leptospirosa of host animals and the immune level of healthy population in flood areas. METHODS: Korth culture was used to culture leptospira for rodent kidney and oxen urine sample. The serogroups of leptospira and leptospira antibody were tested by microscopic agglutination test (MAT). RESULTS: In flood regions, draw-near-flood region, and new migration region, rodent density was 6.95%, 6.28%, and 8.67%, respectively. The positive rates of rodent with leptospira was 4.63%, 1.35%, and 3.13%, respectively. Leptospira positive rates of oxen urine were 5.88%, 5.98%, and 1.75%, respectively. The main serogroup of leptospira was Icterhamorrhagic and Canicola serogroup. The positive rates of leptospirosa antibody in healthy population was 45.91%, 62.30%, and 58.67%in these 3 regions respectively, which was significantly higher than the average level in China. The dominant serogroups of leptospira in health population were icterhamorrhagic, autumnalis, canicola, pomona and bataviae. The positive rate of antibody had no difference among different age groups. CONCLUSION: The main host animals are rodents and oxen infected with leptospira and the positive rate of leptospira antibody is high in healthy population in the study area. The dominant serogroups in host animals are similar to that in healthy population, which is mostly icterhaemorrhagic.

RESUMO

The objective of the study was to construct a short screening scale for posttraumatic stress disorder (PTSD). We used data from our previous study on PTSD among flood victims in 1998 and 1999 in Hunan, China, which was a representative population sample of 27,267 subjects from 16 to 94 years old. Multistage sampling was used to select the subjects from the flood areas and PTSD was ascertained with the Diagnostic and Statistical Manual of Mental Disorders: 4th Edition (DSM-IV). We randomly assigned 80% (n=21,762) of study subjects to construct the screening scale (construct model) and the remaining 20% (n=5505) to test the model. Logistic regression analysis and receiver operating characteristic analysis were used to select a subset of items (symptoms) from the full scale that would effectively predict PTSD. A seven-symptom screening scale for PTSD was selected. A score of 3 or more on this scale was used to define positive cases of PTSD, with a sensitivity of 87.9%, specificity of 97.9%, positive predictive value of 81.3%, and negative predictive value of 98.7%. The short screening scale developed in this study is highly valid, reliable, and predictable. It is an efficient tool to screen PTSD in epidemiological and clinical studies.

RESUMO

Many leguminous species have adapted their seed coat with a layer of powdery bloom that contains hazardous allergens and makes the seeds less visible, offering duel protection against potential predators 1 . Nevertheless, a shiny seed surface without bloom is desirable for human consumption and health, and is targeted for selection under domestication. Here we show that seed coat bloom in wild soybeans is mainly controlled by Bloom1 (B1), which encodes a transmembrane transporter-like protein for biosynthesis of the bloom in pod endocarp. The transition from the 'bloom' to 'no-bloom' phenotypes is associated with artificial selection of a nucleotide mutation that naturally occurred in the coding region of B1 during soybean domestication. Interestingly, this mutation not only 'shined' the seed surface, but also elevated seed oil content in domesticated soybeans. Such an elevation of oil content in seeds appears to be achieved through b1-modulated upregulation of oil biosynthesis in pods. This study shows pleiotropy as a mechanism underlying the domestication syndrome 2 , and may pave new strategies for development of soybean varieties with increased seed oil content and reduced seed dust.

RESUMO

The image segmentation method we use for leucocytes is based on image distance transformation, combining the region and edge approach, taking full advantage of image information. According to the shape, texture and color appearance of cells, we select 22 feature values and measure them. The classifier is designed on the statistical classification. A test for recognizing 831 leucocytes in 560 images shows that the classification accuracy is 96%. Clinical experts confirm this system; for it can automatically recognize leucocytes by pattern recognition technique, and it is demonstrably valid in practice.

RESUMO

OBJECTIVE: To evaluate current club drug use and its potential association with the transmission of HIV/STD among Changsha men who have sex with men (MSM). METHOD: A cross-sectional survey was conducted by using self-administered questionnaires including information regarding socio-demographics, club drug use, high-risk behaviors, and HIV/STD infections. Multiple methods including venue-based, peer referral using "snowball" techniques, and internet advertisements were used to recruit study participants. RESULTS: Of the 826 participants, 177 (21.4%) reported that they had used club drugs at some time before or during sex in the past six months. MSM with young age, low education level, and seeking partners through the internet or bars were the main population who used drugs. Poppers were the most common drug used among Changsha MSM. The prevalence of HIV, syphilis, and herpes simplex virus-2 were higher among drug users. There were no significant differences in unprotected sexual intercourse and condom use between drug users and non-users. Compared with non-users, risk behaviors such as group sex, multiple sex partners, and sex with foreigners were more frequent among drug users. CONCLUSION: Club drug use is common among Changsha MSM, and is related to unsafe sex activities and HIV/STD infection. It is necessary to build novel targeted HIV prevention strategies to monitor and reduce club drug use among MSM.

RESUMO

OBJECTIVE: To explore the prevalence and determinants of chronic post-traumatic stress disorder (PTSD) among flood victims. METHODS: A cross-sectional survey was carried out in 2014 among individuals who had experienced the 1998 floods and had been diagnosed with PTSD in 1999 in Hunan, China. Cluster sampling was used to select subjects from the areas that had been surveyed in 1999. PTSD was diagnosed according to DSM-IV criteria, social support was measured according to a Social Support Rating Scale, coping style was measured according to a Simplified Coping Style Questionnaire, and personality was measured by use of the revised Eysenck Personality Questionnaire Short Scale for Chinese. Data were collected through face-to-face interviews by use of a structured questionnaire. Multivariate logistic regression analysis was used to reveal the determinants of chronic PTSD. RESULTS: A total of 123 subjects were interviewed, 17 of whom (14.4%) were diagnosed with chronic PTSD. Chronic PTSD was significantly associated with disaster stressors (odds ratio [OR]: 1.74; 95% confidence interval [CI]: 1.22-2.47), nervousness (OR: 1.09; 95% CI: 1.01-1.17), and social support (OR: 0.85; 95 CI%: 0.74-0.98). CONCLUSIONS: Chronic PTSD in flood victims is significantly associated with disaster stressors, nervousness, and social support. These factors may play important roles in identifying persons at high risk of chronic PTSD.

RESUMO

OBJECTIVE: To estimate the occurrence and to assess the determinants of posttraumatic stress disorder (PTSD) in flood victims. METHOD: We carried out a retrospective study to examine the occurrence and the determinants of PTSD in victims of flood in 1998 and 1999 in Hunan, China. We used multistage sampling to select the subjects from the flood areas, and we ascertained PTSD according to DSM-IV criteria. Data were collected in face-to-face interviews carried out by experienced research assistants using a preconstructed questionnaire. We used a multiple logistic regression model to analyze the data. RESULTS: A total of 33 340 subjects (86.0% of the selected subjects, aged 7 years or over) in the study villages were interviewed. Among them, 2875 (8.6%) had symptoms that met the diagnostic criteria for PTSD. Significant risk factors for PTSD included female sex (odds ratio [OR] 1.12; 95% confidence interval [CI], 1.04 to 1.21), older age (age 18 to 59 years OR 2.28; 95%CI, 2.02 to 2.57, and age > or = 60 years OR 2.42; 95%CI, 2.05 to 2.85), flood type (collapsed embankment OR 1.84; 95%CI, 1.64 to 2.05, and flash flood OR 3.12; 95%CI, 2.76 to 3.52), and flood severity (intermediate OR 4.05; 95%CI, 3.55 to 4.62, and severe OR 2.98; 95%CI, 2.60 to 3.41). CONCLUSIONS: PTSD is a common mental disorder in flood victims, which implies the need for improved health services, especially mental health services, for this population.

RESUMO

OBJECTIVE: To study the immediate and long-term effects of disasters caused by floods on residents health status. METHODS: Stratified sampling by ranks of flood disaster occurred in 1996 and 1998, flood disaster areas and control areas were carried out. A retrospective study was also carried out to study all diseases involved during 1996 - 1999. RESULTS: The incident rates of acute infectious disease in flooding areas in 1996 and 1998 were both higher than those of non-flooding areas (863.181/100 000 and 736.591/100 000, respectively). But there was no different between the incident rate of the first years in flooding areas and that of non-flooding areas. The prevalence rates of 8 kinds of chronic diseases related to circulatory system, nervous system, digestive system, injury and poisonous diseases in flooding areas were also higher than that in the non-flooding areas. The highest incidence rates of most diseases were in the mountainous flooding areas, followed by areas collapsed by flooding, and the lowest were seen in soakedareas by floods. The incidence rates of intestinal infectious diseases and respiratory infectious diseases were lower in areas where prevention and control measures were weak. CONCLUSION: Flood could lead to the increase of incidence rates both on acute infectious diseases and non-infectious diseases. Interventions on non-infectious diseases should also be enforced to stop the epidemics when preventing and controlling acute infectious disease.

RESUMO

OBJECTIVE: To study the expenses of hospitalization among the population in the flood disaster areas of Dongting Lake in Hunan province in 1998. METHODS: Descriptive epidemiologic study were conducted to analyze hospitalization expenses of the residents of 55 villages in flood disaster areas in 1998; single factors analysis and logarithmic linear regression analysis were carried out to explore influencing factors about hospitalization expenses of the residents. RESULTS: The hospitalization rate was 4.59% with an average hospitalization expenses of 667.42 Yuan in the flood disaster areas' residents of Dongting Lake in 1998. Compared with populations without suffering from flood, hospitalization rate and the average hospitalization expenses of flood disaster Areas' residents of Dongting Lake in 1998 were higher and had significant difference. The average hospitalization expenses in 1998 was affected by flood types, family income, gender, age, literacy, occupation, outcome after leaving the hospital and hospital ranks. CONCLUSION: These results implied that the flood disease aggravated inhabitants' burden of disease in Dongting Lake areas; the factors influencing the average hospitalization expenses were multiple, and synthetic measures should be taken in the prevention and control of flood disaster.
