RESUMO

Several factors, such as pruning and phytohormones, have demonstrated an influence on both the quantity and quality in the bell pepper. A factorial experiment using a completely randomized design was conducted on the Lumos yellow bell in a greenhouse. Treatments were the fruit pruning (0, 10, and 30%) and foliar application of phytohormones auxin (AUX) and gibberellic acid (GA3) at concentrations of 10 µM AUX, 10 µM GA3, 10 µM AUX + 10 µM GA3+, and 20 µM AUX + 10 µM GA3 along with controls. The plants were sprayed with phytohormones in four growth stages (1: flowering stage when 50% of the flowers were on the plant, 2: fruiting stage when 50% of the fruits were the size of peas, 3: fruit growth stage when 50% of the fruits had reached 50% of their growth, and 4: ripening stage when 50% of the fruits were at color break). The results of the present investigation showed that pruning rate of 30% yielded the highest flesh thickness and vitamin C content, decreased seed count and hastened fruit ripening. The use of GA3 along with AUX has been observed to augment diverse fruit quality characteristics. According to the results, the application of 10% pruning in combination with 20 µM AUX and 10 µM GA3 demonstrated the most significant levels of carotenoids, chlorophyll, and fruit length. The experimental group subjected to the combined treatment of 30% pruning and 10 µM AUX + 10 µM GA3 showed the most noteworthy levels of vitamin C, fruit weight, and fruit thickness. The groups that received the 10 µM GA3 and 20 µM AUX + 10 µM GA3 treatments exhibited the most favorable fruit flavor. According to the research results, the implementation of hormonal treatments 10 µM AUX and 10 µM AUX + 10 µM GA3 in combination with a 30% pruning strategy resulted in the most advantageous yield of bell peppers.

RESUMO

BACKGROUND: FCSK-congenital disorder of glycosylation (FCSK-CDG) is a recently discovered rare autosomal recessive genetic disorder with defective fucosylation due to mutations in the fucokinase encoding gene, FCSK. Despite the essential role of fucokinase in the fucose salvage pathway and severe multisystem manifestations of FCSK-CDG patients, it is not elucidated which cells or which types of fucosylation are affected by its deficiency. METHODS: In this study, CRISPR/Cas9 was employed to construct an FCSK-CDG cell model and explore the molecular mechanisms of the disease by lectin flow cytometry and real-time PCR analyses. RESULTS: Comparison of cellular fucosylation by lectin flow cytometry in the created CRISPR/Cas9 FCSK knockout and the same unedited cell lines showed no significant change in the amount of cell surface fucosylated glycans, which is consistent with the only documented previous study on different cell types. It suggests a probable effect of this disease on secretory glycoproteins. Investigating O-fucosylation by analysis of the NOTCH3 gene expression as a potential target revealed a significant decrease in the FCSK knockout cells compared with the same unedited ones, proving the effect of fucokinase deficiency on EGF-like repeats O-fucosylation. CONCLUSION: This study expands insight into the FCSK-CDG molecular mechanism; to the best of our knowledge, it is the first research conducted to reveal a gene whose expression level alters due to this disease.

RESUMO

OBJECTIVE: Cervical ectropion occurs due to the eversion of the endocervix that exposes glandular cells to the vaginal milieu. The aim of the present study was to evaluate and compare the clinical efficacy of effervescent vaginal tablets of tranexamic acid and cryotherapy in women with symptomatic cervical ectopy. METHODS: The current randomized clinical trial was conducted on 92 samples of women with cervical erosive ectropion from March 20, 2022 to August 27, 2022. Participants were divided into two groups; the intervention group (n = 46) was treated with a 400 mg effervescent vaginal tablet of tranexamic acid and the control group (n = 46) underwent cryotherapy. All the patients were requested to visit weekly in the first month and then monthly for the next 3 months, and the outcomes encompass improvement of symptoms (leukorrhea, dyspareunia, pelvic pain, post-coital bleeding, and suprapubic pain) and cervical erosive ectropion view were monitored based on repeated examinations. RESULTS: In this study, no statistically significant difference was observed in cure rate of symptoms between study groups (P value > 0.05). Women in both the tranexamic acid and cryotherapy groups reported significant improvements in dyspareunia (34 [75%] vs 31 [67%]), pelvic pain (34 [75%] vs 34 [74%]), post-coital bleeding (37 [81%] vs 31 [67%]), leukorrhea (36 [78%] vs 36 [78%]), suprapubic pain (32 [71%] vs 33 [73%]) disappearance of cervical ectropion tranexamic acid (40 [86%], vs 39 [84%]). CONCLUSION: Our findings highlighted the equal effect of tranexamic acid and cryotherapy for treating cervical ectropion. Due to the ease of use, availability, and fewer side effects of tranexamic acid, it can be a suitable alternative to cryotherapy. TRIAL REGISTRATION: IRCT20220115053719N1.

RESUMO

Damask rose (Rosa damascena Mill.) is an aromatic industrial plant with different applications. Selection of cultivars with high-value metabolites such as flavonoids-with acceptable yields-can lead to elite cultivars for mass propagation in various industries. A field experiment was carried out in a randomized complete block design (RCBD) to evaluate metabolites and some yield-related morphological data. In the present investigation, for the first time 13 flavonoid components of nine Iranian damask rose cultivars were compared using LC-MS/MS. As a result, 13 flavonoids were identified, most of which were reported for the first time in rose petals. Phloridzin (72.59-375.92 mg/100 g dw), diosmetin (82.48-153.16 mg/100 g dw) and biochanin A (0-1066.89 mg/100 g dw) were the most abundant, followed by trans-chalcone (0-106.29 mg/100 g dw) and diosmin (41.55-84.57 mg/100 g dw). Levels of naringenin also ranged from 3.77 in B111 to 54.70 mg/100 g dw in C294, while luteolin varied from 4.37 in B111 to 28.87 mg/100 g dw in C294. The SPME Arrow technique also was applied to determine the real aroma of the studied cultivars. Phenethyl alcohol was the most abundant compound, in the range of 69.28 to 77.58%. The highest citronellol/geraniol (C/G) was observed in D234 (4.52%) and D237 (4.30%), while the lowest amount belonged to A104 (1.28%). Rose oxide, as the most crucial factor for odor, ranged from 0.06% in D237 to 0.15% in D211. Based on cluster and principal component analysis (PCA), D234 cultivar can be suggested as a promising cultivar with high yield, high C/G content and high rose oxide, while D234 and C294 were the most valuable cultivars in terms of flavonoids with high yield. Finally, these cultivars can be introduced for further breeding programs and industrial cultivation.

RESUMO

Drought due to climate change or reduced precipitation is one of the main factors limiting the growth and establishment of plants and is one of the most critical challenges facing humans. To investigate the effect of different levels of drought stress on some pine species, this research was carried out as a factorial experiment using two factors and a completely randomized design. It included five populations of four pine species (Pinus brutia Ten. var. eldarica, P. nigra Arnold, P. mugo, and P. banksiana Lamb (including populations 8310055 and 8960049), and three levels of irrigation (100%, 75%, or 50% FC, denoted as normal, mild or intense drought stress, respectively) with three replicates. The findings showed that, photosynthetic pigments, relative water content, visual quality, the content of nutrients, protein content, and fresh and dry weight all decreased significantly when plants were exposed to intense drought stress. However, raised proline levels, electrolyte leakage percentage, soluble sugars levels, and antioxidant enzyme activity. We detected a decline in most growth traits when comparing mild drought stress conditions to normal irrigation, yet acceptable quality seedlings when compared to intense drought stress. Intense drought stress had a substantial impact on many pine seedlings. PCA results showed that among different pine species, the level of resistance to drought is as follows: P. mugo> P. brutia var. eldarica> P. nigra> P. banksiana 8310055> P. banksiana 8960049. Our novel finding was that, P. mugo is a resistant species in arid and semi-arid regions, and P. banksiana species, especially its population of 8960049, is sensitive.

RESUMO

In multiple sclerosis (MS), activation of the astrocytes and microglia induces a cascading inflammatory response. Overexpression of the aquaporin 4 (AQP4) in the glia is a trigger for this reaction. This study aimed to block AQP4 by injecting TGN020 to alleviate the symptoms of MS. Total of 30 male mice were randomly divided into control (intact), cuprizone model of MS (fed with 0.2% cuprizone for 35 days), and TGN020-treated (received daily intraperitoneal injections of 200 mg/kg TGN020 with cuprizone intake) groups. Astrogliosis, M1-M2 microglia polarization, NLRP3 inflammasome activation, and demyelination were investigated in the corpus callosum by immunohistochemistry, real-time PCR, western blot, and luxol fast blue staining. The Rotarod test was performed for a behavior assessment. AQP4 inhibition caused a significant decrease in the expression of the astrocyte-specific marker, GFAP. It also changed the microglia polarization from M1 to M2 indicated by a significant downregulation of iNOS, CD86, MHC-ІІ, and upregulation of arginase1, CD206, and TREM-2. In addition, western blot data showed a significant decrease in the NLRP3, caspase1, and IL-1b proteins in the treatment group, which indicated inflammasome inactivation. The molecular changes following the TGN020 injection resulted in remyelination and motor recovery enhancement in the treatment group. In conclusion, the results draw the attention to the role of AQP4 in the cuprizone model of MS.

RESUMO

Pathogenic variants in the EDARADD gene result in autosomal recessive and autosomal dominant ectodermal dysplasia. This article reports on the fourth family in the world with ectodermal dysplasia 11A (ECTD11A) cause from a novel splicing variant in the EDARADD gene, identified by whole exome sequencing and confirmed by Sanger sequencing. The proband and his mother were heterozygous for the detected variant (NM_145861.4:c.161-2A>T). The proband manifests unusual symptoms including hyperkeratotic plaques, slow-growing hair, recurrent infection, and pectus excavatum. His mother presents hypohidrosis, extensive tooth decay, fragile nails, and sparse hair. Further studies on ECTD11A patients could be useful to characterizing the phenotype features more precisely.

RESUMO

Objective: This study aimed to evaluate the Iranian ophthalmologists' knowledge of prescribing prophylactic antibiotics to patients with open globe injury (OGI) in Iran. Methods: In this cross-sectional study, we utilized a questionnaire to evaluate the ophthalmologists' knowledge about prescribing antibiotics as prophylaxis. This survey was conducted in Tehran and its suburbs. The questionnaire included demographic information as well as ophthalmologists' knowledge levels. Cronbach's alpha was used to determine its validity and reliability. The obtained data were analyzed using SPSS 24.0. Results: Of 192 subjects, 111 (35 women, 76 men) were included. About 65 (58.6%) specialists and 45 (41.4%) subspecialists with different orientations completed the questionnaires. The total knowledge score was 13.04±2.96. The following are the results of ophthalmologists' responses to questions regarding the cornea/scleral injury (1.09±1.72), prophylactic antibiotics administration (2.79±1.11), the infectious agents in eye surgeries (3.21±1.49), diagnosis and treatment (2.84±0.944), and the effects of ocular antibiotics as well as their proper dosage (2.96±2.35). There was no significant relationship between some demographic information such as sex, working hours, workplace, and the number of studied articles (p>0.05). In addition, ophthalmologists with less work experience had significantly higher levels of knowledge than those with more work experience. Conclusion: The findings indicated that the majority of ophthalmologists had a basic knowledge of prescribing prophylactic antibiotics in OGI.

RESUMO

Although the role of myo-inositol (MYO) in promoting the oocyte quality of PCOS patients has been documented in human studies; the cellular effects of this supplement on oocytes have not been directly examined due to ethical limitations. In the first phase of this study, MYO dosimetry was carried out simultaneously with the PCOS model development. An effective dose was obtained following the assessment of fasting insulin and testosterone levels using ELISA and ovarian morphology appraisal by histopathology. In the second phase, following the continuous administration of the effective dose of MYO and dehydroepiandrosterone (DHEA), cellular evaluation was performed. The quality of oocytes from superovulation was analyzed by examining maturity and normal morphology percentage using a stereomicroscope, intracellular reactive oxygen species (ROS) and glutathione (GSH) levels using fluorometry, and ATP count evaluation using ELISA. The results revealed that, among the four different MYO concentrations, the 0.36 mg/g dose compared with the DHEA group reduced testosterone levels and large atretic antral follicles (LAtAnF) diameter. This dose also increased the corpus luteum count and the granulosa:theca (G/T)layer thickness ratio in antral follicles. Furthermore, this dose increased mature oocytes and normal morphology percentage, ATP count, and GSH levels; however, it decreased ROS levels in mature oocytes. Our findings provide the grounds for further cellular and molecular studies on the PCOS mouse model, suggesting that the improvement in mitochondrial function and its antioxidant properties is probably one of the mechanisms by which MYO increases oocyte quality.

RESUMO

In this study, the interaction of an anticonvulsant drug that used in the treatment of epilepsy, Lamotrigine (LTG) with the most important transport protein of the blood, human serum albumin (HSA) has been studied by using the electrochemical methods and molecular modeling techniques. For this purpose, a simple carbon paste electrode (CPE) was applied for electrocatalytic oxidation and investigation of LTG interaction with HSA. The stoichiometry of the complex between LTG and HSA and the binding constant (Kb) of the reaction were calculated from the calibration curves. The results show that binding of LTG to HSA formed two complexes with different stoichiometries with Kb1 (2.46 × 103) and Kb2 (1.75 × 107), respectively. In agreement with the experimental data, molecular modeling approach also confirmed that LTG can bind to the subdomain IIA and IB of HSA.Communicated by Ramaswamy H. Sarma.

RESUMO

Using organic fertilizer as part of plant nutrition for decreasing using chemical fertilizer and increasing plants' nutritional value is scientists' concern. Treatments were three concentrations of a mixture of 16 different AAs (amino acid) (0, 150 and 300 mg/L), sprayed every 7 days for 2 months on 4 leafy cabbages. Results showed 300 mg/L AAs increased anthocyanin, flavonoids, phenol, protein and proline. The SOD, POX and APX rose upon AAs usage. The application of AA significantly increased the total chlorophyll, proline, carotenoid, anthocyanin, phenol, protein and flavonoids compared to control plants. The levels of glucosinolate were increased especially in the treatment of 300 mg/L of AAs and glucobrassicin and gluconapin, both of these together represent more than 50% of the total glucosinolate contents. The highest levels of phenolic and flavonoids mostly belonged to quercetin and catechin. Total AAs and total non-essential AAs showed the highest amounts in all treatments in leaves. AAs with different concentrations by foliar application in "Ka- scotch" variety were effective in growth, physiological parameters such as plant height and shoot dry weight, while AA changes were effective in most of the biochemical and nutritional traits of "Ka-red" variety. Conclusively, the glucosinolate, phenolic and flavonoid contents and AAs varied between four cabbage cultivars. Exogenous AAs application at 300 mg/L could be recommended for cabbage cultivation to improve growth, biochemical traits, productivity and nutritional value.

RESUMO

Pathogenic variants in FCSK cause Congenital Disorder of Glycosylation with Defective Fucosylation-2 (FCSK-CDG; MIM: 618,324). It is a rare autosomal recessive genetic disease caused by defects in the L-fucose kinase, which is necessary for the fucose salvage pathway. Herein, we report two novel variants in an Iranian patient, the fourth individual with FCSK-CDG described in the literature. Two homozygous variants in FCSK (rs376941268; NM_145059.3: c.379C > A, p. Leu127Met and rs543223292; NM_145059.3: c.394G > C, p. Asp132His) were identified in the proband. Sanger sequencing conducted on his unaffected parents revealed that they were heterozygous for the same variants. The proband, a four-and-a-half year old Iranian male born to consanguineous parents, manifested Intellectual disability, growth delay, ophthalmic abnormalities, seizures, speech disorder, and feeding difficulties.

RESUMO

Background and purpose: Since insulin and pramlintide cooperate in glucose hemostasis, co-administration and quantitation of them in pharmaceutical preparations are imperative. A simple, rapid, sensitive, and isocratic RP-HPLC method was developed and validated for simultaneous quantitation of insulin and pramlintide in loading and in-vitro release studies of a glucose-responsive system to improve the control of hyperglycemic episodes in diabetic patients. Experimental approach: The isocratic RP-HPLC separation was achieved on a C18 µ-Bondopak column (250 mm × 4.6 mm) using a mobile phase of water:acetonitrile:trifluoroacetic acid (65:35:0.1%) at a flow rate of 1 mL/min in an ambient temperature. Both proteins were detected using a UV detector at 214 nm. The method was validated for specificity, linearity, precision, accuracy, the limit of detection, the limit of quantification, and robustness. Findings/Results: Linearity was obtained in the concentration range of 30 to 360 µg/mL for insulin and 1.5 to 12 µg/mL for pramlintide. The results were validated statistically and recovery studies confirmed the great accuracy and precision of the proposed method. The robustness of the method was also confirmed through small changes in pH, mobile phase composition, and flow rate. Conclusion and implications: The method was found to be simple, specific, precise, and reproducible. It was applied for the determination of loading capacity, entrapment efficiency, and in-vitro release studies of insulin and pramlintide in a smart glucose-responsive microparticle. Co-delivery of insulin and pramlintide could be a new intervention in diabetes management and concurrent quantitation of these two proteins is, therefore, essential.

RESUMO

BACKGROUND: Spinach is a beneficial annual vegetable species and sensitive to the bolting or early flowering, which causes a large reduction in quality and productivity. Indeed, bolting is an event induced by the coordinated effects of various environmental factors and endogenous genetic components. Although some key flowering responsive genes have been identified in spinach, non-coding RNA molecules like long non-coding RNAs (lncRNAs) were not investigated yet. Herein, we used bioinformatic approaches to analyze the transcriptome datasets from two different accessions Viroflay and Kashan at two vegetative and reproductive stages to reveal novel lncRNAs and the construction of the lncRNA-mRNA co-expression network. Additionally, correlations among gene expression modules and phenotypic traits were investigated; day to flowering was chosen as our interesting trait. RESULTS: In the present study, we identified a total of 1141 lncRNAs, of which 111 were differentially expressed between vegetative and reproductive stages. The GO and KEGG analyses carried out on the cis target gene of lncRNAs showed that the lncRNAs play an important role in the regulation of flowering spinach. Network analysis pinpointed several well-known flowering-related genes such as ELF, COL1, FLT, and FPF1 and also some putative TFs like MYB, WRKY, GATA, and MADS-box that are important regulators of flowering in spinach and could be potential targets for lncRNAs. CONCLUSIONS: This study is the first report on identifying bolting and flowering-related lncRNAs based on transcriptome sequencing in spinach, which provides a useful resource for future functional genomics studies, genes expression researches, evaluating genes regulatory networks and molecular breeding programs in the regulation of the genetic mechanisms related to bolting in spinach.

RESUMO

Intrauterine inflammation affects fetal development of the nervous system and may cause prenatal brain injury in offspring. Previously, neural stem cells have been extensively used as a therapeutic choice for nervous system diseases. Recently, the therapeutic ability of conditioned medium, harvested from cultured stem cells, has captured the attention of researchers in the field. Our study aimed to compare the therapeutic effect of neural stem cells (NSCs) or NSC-conditioned medium (NSC-CM) after prenatal brain injury. The animal model was induced by intraperitoneal injection of lipopolysaccharide into the pregnant mice and NSCs or NSC-CM were transplanted into the lateral ventricle of embryos in treatment groups. Inflammation and apoptosis were evaluated postpartum in offspring via measuring the expression of NLRP3 gene and protein, the expression and the activity of caspase-3, and the expression of pro-inflammatory cytokines by real-time PCR, immunohistochemistry, western blotting, ELISA, and colorimetric assay kit. A rotarod test was performed for motor function evaluation. Data showed that although NSC-CM fought against the inflammation and apoptosis and improved the motor function, NSCs acted more efficiently. In conclusion, the results of our study contend that NSCs have a better therapeutic effect than CM in prenatal brain injury.

RESUMO

High salt levels are one of the significant and major limiting factors on crop yield and productivity. Out of the available attempts made against high salt levels, engineered nanoparticles (NPs) have been widely employed and considered as effective strategies in this regard. Of these NPs, titanium dioxide nanoparticles (TiO2 NPs) and selenium functionalized using chitosan nanoparticles (Cs-Se NPs) were applied for a quite number of plants, but their potential roles for alleviating the adverse effects of salinity on stevia remains unclear. Stevia (Stevia rebaudiana Bertoni) is one of the reputed medicinal plants due to their diterpenoid steviol glycosides (stevioside and rebaudioside A). For this reason, the current study was designed to investigate the potential of TiO2 NPs (0, 100 and 200 mg L-1) and Cs-Se NPs (0, 10 and 20 mg L-1) to alleviate salt stress (0, 50 and 100 mM NaCl) in stevia. The findings of the study revealed that salinity decreased the growth and photosynthetic traits but resulted in substantial cell damage through increasing H2O2 and MDA content, as well as electrolyte leakage (EL). However, the application of TiO2 NPs (100 mg L-1) and Cs-Se NPs (20 mg L-1) increased the growth, photosynthetic performance and activity of antioxidant enzymes, and decreased the contents of H2O2, MDA and EL under the saline conditions. In addition to the enhanced growth and physiological performance of the plant, the essential oil content was also increased with the treatments of TiO2 (100 mg L-1) and Cs-Se NPs (20 mg L-1). In addition, the tested NPs treatments increased the concentration of stevioside (in the non-saline condition and under salinity stress) and rebaudioside A (under the salinity conditions) in stevia plants. Overall, the current findings suggest that especially 100 mg L-1 TiO2 NPs and 20 mg L-1 Cs-Se could be considered as promising agents in combating high levels of salinity in the case of stevia.

RESUMO

OBJECTIVE: We investigated the effects of replacing regular outpatient follow-up through prescheduled visits with patient-initiated visits on patient satisfaction and clinical variables of type 1 diabetes (T1D). RESEARCH DESIGN AND METHODS: A 24-month randomized controlled trial in which adults with T1D were allocated to either patient-initiated unlimited access to outpatient visits or usual care through regular prescheduled visits. The primary outcome was seven patient-reported experience measures of patient satisfaction focused on benefit of consultation and accessibility of the outpatient clinic. Secondary outcomes included clinical variables of diabetes and use of staff resources. RESULTS: We enrolled 357 outpatients (intervention, n = 178; control, n = 179). After 24 months, participants in the intervention group experienced more benefit from consultations compared with baseline within groups (P < 0.05) and fewer unnecessary visits compared with control subjects (P < 0.05). Patient needs covered and satisfaction with the outpatient clinic were high and unchanged in both groups, and accessibility was increased (three questions, all P < 0.05). A calculated seven-item patient satisfaction sum score favored the intervention group over control subjects (P < 0.001). There were no significant changes in glycated hemoglobin (HbA1c), LDL, blood pressure, and complication status. The mean number of outpatient visits over 24 months (± SD) was lower in the intervention group compared with control subjects (4.4 ± 2.8 vs. 6.3 ± 2.7; P < 0.001), while the number of telephone contacts was higher (3.1 ±3.4 vs. 2.5 ± 3.2; P < 0.001). CONCLUSIONS: Patient satisfaction remained high or improved with patient-initiated on-demand use of the diabetes outpatient clinic, with no decline in the quality of diabetes care, and a reduction in the use of staff resources.

RESUMO

Both extreme usage of water in agriculture i.e., drought and flooding affect physiological and growth aspects of the plant as well as gene expression undertaken in water absorption. These affect depend on the stress duration i.e., shock or gradual stress exposer. The factorial experiment based on CRD with 10 replicates was conducted to investigate the physiological and water relation as well as aquaporin expression in (Capsicum annuum L.). Drought stress was applied gradually from - 2, - 3, - 4 to - 5 MPa during 8 days but in shock stress - 5 MPa applied at one time. The gradual flooding stress adjusted with changing the aeration duration from 15 to 0 min gradually every 2 days and for the shock- flooding, peppers keep in a nutrient solution without aeration in a sealed container. Results showed that both extreme water stress had a deleterious effect on the growth and physiological parameter of pepper for a longer duration. Antioxidant, proline, fluorescence chlorophyll stimulate in the gradual period except for ABA content, which is higher in shock stress. PIP1expression showed a reverse effect in leaf and root at flooding i.e., PIP1expression raised in root while it was reduced in leaf at shock-flooding. The highest PIP1expression was observed in gradual-drought of root and gradual duration of drought and flooding stress in leaf. In the physiological aspect of plant response to stress in pepper, results showed an enhanced in proline and phenol content to help osmotic adjustment and keep water status in moderate condition. Conclusively, shocked stress first, motivated these defense systems, and then in the next step, the other adaptive mechanism like gene expression activated to help pepper face stress. On the other hand, shock stress showed down-regulation, but when the stress lasted for a longer time results in up-regulation.

RESUMO

BACKGROUND: Bolting refers to the early flowering stem production on agricultural and horticultural crops before harvesting. Indeed, bolting is an event induced by the coordinated effects of various environmental factors and endogenous genetic components, which cause a large reduction in the quality and productivity of vegetable crops like spinach. However, little is known about the signaling pathways and molecular functions involved in bolting mechanisms in spinach. The genetic information regarding the transition from vegetative growth to the reproductive stage in spinach would represent an advantage to regulate bolting time and improvement of resistant cultivars to minimize performance loss. RESULTS: To investigate the key genes and their genetic networks controlling spinach bolting, we performed RNA-seq analysis on early bolting accession Kashan and late-bolting accession Viroflay at both vegetative and reproductive stages and found a significant number of differentially expressed genes (DEGs) ranging from 195 to 1230 in different comparisons. These genes were mainly associated with the signaling pathways of vernalization, photoperiod/circadian clock, gibberellin, autonomous, and aging pathways. Gene ontology analysis uncovered terms associated with carbohydrate metabolism, and detailed analysis of expression patterns for genes of Fructose-1, 6-bisphosphate aldolase, TREHALOSE-6-PHOSPHATE SYNTHASE 1, FLOWERING PROMOTING FACTOR 1, EARLY FLOWERING, GIGANTEA, and MADS-box proteins revealed their potential roles in the initiating or delaying of bolting. CONCLUSION: This study is the first report on identifying bolting and flowering-related genes based on transcriptome sequencing in spinach, which provides insight into bolting control and can be useful for molecular breeding programs and further study in the regulation of the genetic mechanisms related to bolting in other vegetable crops.

RESUMO

OBJECTIVE: Isolated nonsyndromic sagittal synostosis (SS) is the most common form of craniosynostosis in children, accounting for approximately 60% of all craniosynostoses. The typical cranial measurement used to define and follow SS is the cephalic index (CI). Several surgical techniques have been suggested, but agreement on type and timing of surgery is lacking. This study aimed to evaluate the authors' institutional experience of surgically treating SS using a modified subtotal cranial vault remodeling technique in a population-based cohort. Special attention was directed toward the effect of patient age at time of surgery on long-term CI outcome. METHODS: A retrospective analysis was conducted on all patients with isolated nonsyndromic SS who were surgically treated from 2003 to 2011. Data from electronic medical records were gathered. Eighty-two patients with SS were identified, 77 fulfilled inclusion criteria, and 72 had sufficient follow-up data and were included. CI during follow-up after surgery was investigated with ANOVA and a linear mixed model. RESULTS: In total, 72 patients were analyzed, consisting of 16 females (22%) and 56 males (78%). The mean ± SD age at surgery was 4.1 ± 3.1 months. Blood transfusions were received by 81% of patients (26% intraoperatively, 64% postoperatively, 9% both). The mean ± SD time in the pediatric ICU was 1.1 ± 0.25 days, and the mean ± SD total hospital length of stay was 4.6 ± 2.0 days. No patient required reoperation. The mean ± SD CI increased from 69 ± 3 to 87 ± 5 for patients who underwent surgery before 45 days of age. Surgery resulted in a larger increase in CI for patients who underwent surgery at a younger age compared with older patients (p < 0.05, Tukey's HSD test). In the comparison of patients who underwent surgery before 45 days of age with patients who underwent surgery at 45-90, 90-180, and more than 180 days of age, the linear mixed model estimated a long-term loss of CI of 3.0, 5.5, and 7.4 points, respectively. CONCLUSIONS: The modified subtotal cranial vault remodeling technique used in this study significantly improved CI in patients with SS. The best results were achieved when surgery was performed early in life.
