Gibberellin and miRNA156-targeted SlSBP genes synergistically regulate tomato floral meristem determinacy and ovary patterning.

Many developmental processes associated with fruit development occur at the floral meristem (FM). Age-regulated microRNA156 (miR156) and gibberellins (GAs) interact to control flowering time, but their interplay in subsequent stages of reproductive development is poorly understood. Here, in tomato (Solanum lycopersicum), we show that GA and miR156-targeted SQUAMOSA PROMOTER-BINDING PROTEIN-LIKE (SPL or SBP) genes interact in the tomato FM and ovary patterning. High GA responses or overexpression of miR156 (156OE), which leads to low expression levels of miR156-silenced SBP genes, resulted in enlarged FMs, ovary indeterminacy and fruits with increased locule number. Conversely, low GA responses reduced indeterminacy and locule number, and overexpression of a S. lycopersicum (Sl)SBP15 allele that is miR156 resistant (rSBP15) reduced FM size and locule number. GA responses were partially required for the defects observed in 156OE and rSBP15 fruits. Transcriptome analysis and genetic interactions revealed shared and divergent functions of miR156-targeted SlSBP genes, PROCERA/DELLA and the classical WUSCHEL/CLAVATA pathway, which has been previously associated with meristem size and determinacy. Our findings reveal that the miR156/SlSBP/GA regulatory module is deployed differently depending on developmental stage and create novel opportunities to fine-tune aspects of fruit development that have been important for tomato domestication.

Effect of transcranial direct current stimulation combined with pelvic muscle training in women: Randomized, controlled, double-blind, and clinical trial.

BACKGROUND: Pelvic floor muscle training (PFMT) is widely used for pelvic floor muscle (PFM) weakness in women; however, it has no prolonged effects. OBJECTIVE: To evaluate the effect of Transcranial Direct Current Stimulation (tDCS) associated with PFMT on PFM contraction, sexual function and quality of life (QoL) in healthy women. STUDY DESIGN: 32 nulliparous women, aged 22.7 ± 0.42 years, were randomized into two groups: G1 (active tDCS combined with PFMT) and G2 (sham tDCS combined with PFMT). The treatment was performed three times a week for 4 weeks, totaling 12 sessions. PFM function was assessed using the PERFECT scheme (P = power, E = endurance, R = repetitions, F = rapid contractions, ECT = each timed contraction) and the perineometer (cmH2O). Sexual function was assessed by The Female Sexual Function Index, and QoL by the SF-36 questionnaire. These assessments were performed before and after the 12nd treatment session and after 30-day follow-up. RESULTS: There was a significant increase (p = 0.037) in the power of G2 compared to G1; repetitions and fast contraction increased in the G1 group, and the resistance increased in both groups, however, without statistical difference between the groups. ECT increased in the G1 group (p = 0.0). CONCLUSION: Active tDCS combined with PFMT did not potentiate the effect of the PFMT to increase the PFM function, QoL, and sexual function in healthy women. However, adjunctive tDCS to PFMT improved the time of contractions, maintaining it during follow-up.

Tomato miR156-targeted SlSBP15 represses shoot branching by modulating hormone dynamics and interacting with GOBLET and BRANCHED1b.

The miRNA156 (miR156)/SQUAMOSA PROMOTER-BINDING PROTEIN-LIKE (SPL/SBP) regulatory hub is highly conserved among phylogenetically distinct species, but how it interconnects multiple pathways to converge to common integrators controlling shoot architecture is still unclear. Here, we demonstrated that the miR156/SlSBP15 node modulates tomato shoot branching by connecting multiple phytohormones with classical genetic pathways regulating both axillary bud development and outgrowth. miR156-overexpressing plants (156-OE) displayed high shoot branching, whereas plants overexpressing a miR156-resistant SlSBP15 allele (rSBP15) showed arrested shoot branching. Importantly, the rSBP15 allele was able to partially restore the wild-type shoot branching phenotype in the 156-OE background. rSBP15 plants have tiny axillary buds, and their activation is dependent on shoot apex-derived auxin transport inhibition. Hormonal measurements revealed that indole-3-acetic acid (IAA) and abscisic acid (ABA) concentrations were lower in 156-OE and higher in rSBP15 axillary buds, respectively. Genetic and molecular data indicated that SlSBP15 regulates axillary bud development and outgrowth by inhibiting auxin transport and GOBLET (GOB) activity, and by interacting with tomato BRANCHED1b (SlBRC1b) to control ABA levels within axillary buds. Collectively, our data provide a new mechanism by which the miR156/SPL/SBP hub regulates shoot branching, and suggest that modulating SlSBP15 activity might have potential applications in shaping tomato shoot architecture.

A Virtual Assistant in Vaccine Pharmacovigilance: Content and Usability Validation.

This article describes the process of developing and validating a virtual assistant to perform vaccine pharmacovigilance. We performed a pilot study with a panel of 22 healthcare professionals who performed content validation of the virtual assistant prototype. Usability was tested with 126 users, using the System Usability Scale. The data analysis was performed by the agreement rate and content validity index, and the κ test was used to verify the agreement between the evaluators. The content domains of the virtual assistant achieved excellent suitability, relevance, and representativeness criteria, all greater than 86%; the content validity index ranged from 0.81 to 0.98, with an average of 0.90 and an interrater reliability index of 1.00. There was excellent interrater agreement (average κ value, 0.76). The total usability score among users was 80.1, ranging from 78.2 in group 1 (users without reactions to vaccines) to 82.1 in group 2 (users with reactions) ( P = .002). The virtual assistant for vaccine pharmacovigilance obtained a satisfactory level of content validity and usability, giving greater credibility to the claim that this device provides greater surveillance and safety for patients.

Acute arterial occlusion resulting from paradoxical embolism - case report and literature review.

A embolia paradoxal é a transposição de um trombo originário da circulação sistêmica venosa para a arterial através de um defeito cardíaco, mais comumente o forame oval pérvio (FOP). A manifestação mais comum é o acidente cerebrovascular. A oclusão arterial aguda (OAA) é rara, requer alta suspeição diagnóstica e corresponde a menos de 2% de todos casos de embolia arterial. O tromboembolismo pulmonar (TEP) é a causa mais comum de elevação temporária do shunt direita-esquerda em pacientes com FOP e ocorre em pelo menos 60% dos casos de embolia paradoxal. Em 2019, um homem de 27 anos, sem fator para hipercoagulabilidade, deu entrada no Hospital Universitário do ABC, com quadro de OAA grau I Rutherford em membros inferiores secundária a tromboembolismo através de FOP prévio não diagnosticado, associado a trombose venosa profunda de membro inferior direito e TEP bilateral. O manejo incluiu anticoagulação plena e encaminhamento para cirurgia cardíaca.

In this case report, we describe diagnosis and treatment in a young pregnant patient, with excellent clinical response.

A vasculopatia livedoide é uma doença caracterizada pela oclusão dos capilares da derme, sem sinais inflamatórios. Tem início com pápulas ou máculas purpúricas que evoluem para úlceras dolorosas, com predominância na topografia de tornozelos e pés. Neste relato de caso, descrevemos o diagnóstico e a terapêutica em uma paciente jovem gestante, com excelente evolução clínica.

Tomato floral induction and flower development are orchestrated by the interplay between gibberellin and two unrelated microRNA-controlled modules.

Age-regulated microRNA156 (miR156) and targets similarly control the competence to flower in diverse species. By contrast, the diterpene hormone gibberellin (GA) and the microRNA319-regulated TEOSINTE BRANCHED/CYCLOIDEA/PCF (TCP) transcription factors promote flowering in the facultative long-day Arabidopsis thaliana, but suppress it in the day-neutral tomato (Solanum lycopersicum). We combined genetic and molecular studies and described a new interplay between GA and two unrelated miRNA-associated pathways that modulates tomato transition to flowering. Tomato PROCERA/DELLA activity is required to promote flowering along with the miR156-targeted SQUAMOSA PROMOTER BINDING-LIKE (SPL/SBP) transcription factors by activating SINGLE FLOWER TRUSS (SFT) in the leaves and the MADS-Box gene APETALA1(AP1)/MC at the shoot apex. Conversely, miR319-targeted LANCEOLATE represses floral transition by increasing GA concentrations and inactivating SFT in the leaves and AP1/MC at the shoot apex. Importantly, the combination of high GA concentrations/responses with the loss of SPL/SPB function impaired canonical meristem maturation and flower initiation in tomato. Our results reveal a cooperative regulation of tomato floral induction and flower development, integrating age cues (miR156 module) with GA responses and miR319-controlled pathways. Importantly, this study contributes to elucidate the mechanisms underlying the effects of GA in controlling flowering time in a day-neutral species.

Adult dyskinetic cerebral palsy: Upper limb movement and muscle function.

AIM: The aim of this study was to characterize upper limb motor function during a comparative analysis of electromyographic and upper limb movement analysis during drinking between healthy adults and individuals with DCP. METHOD: Fifteen healthy individuals (CG) and fifteen individuals with DCP (DG) participated in the study. Upper limb function was analyzed during drinking and consisted of a task divided into three phases: the going, the adjustment, and the return. RESULTS: Electromyographic analysis revealed a lower activity of the anterior deltoid, posterior deltoid, and biceps brachii muscles in the DG. When comparing the interactions between groups and phases, only biceps brachii shower lower muscle activity during going and adjustment phases. The DG presented a smaller range of motion (ROM) for the shoulder, elbow, forearm and wrist movements. An interaction between groups and phases showed smaller ROM for the flexion and internal rotation of the shoulder, elbow flexion, forearm pronation, and ulnar deviation in the return phase compared to CG. INTERPRETATION: The results may contribute positively to the quantification of the level of motor impairment and may be used as a reference for the development of therapeutic interventions for patients with DCP.

Algorithm for diagnosis of primary vasculitides.

Primary vasculitides are diseases with a wide variety of anatomical, clinical, radiological, and laboratory presentations. Primary vasculitides are difficult to diagnose because of the complexity of clinical presentation, which may lead to delayed treatment and increased financial costs of workup investigations involving non-essential tests. Our objective in the present study is to create an algorithm that helps diagnosis of Primary vasculitides. The algorithm presented in this article allows fast, simple and cost-effective diagnosis of primary vasculitides using just clinical concepts and a few laboratory tests.

As vasculites primárias são doenças que possuem apresentações anatômicas, clínicas, radiológicas e laboratoriais muito distintas. Em virtude da complexidade dos quadros clínicos apresentados, as vasculites primárias são de difícil diagnóstico, o que pode promover um retardo no início da terapêutica, além de aumentar os custos financeiros da investigação propedêutica com exames não essenciais. O objetivo deste estudo foi criar um algoritmo que auxilie o diagnóstico das vasculites primárias. O algoritmo apresentado neste artigo permite a realização de diagnóstico rápido, simples e de baixo custo nas vasculites primárias, com a utilização de alguns conceitos clínicos e poucos exames laboratoriais.

Influence of polidocanol ultrasound-guided foam sclerotherapy on quality of life in lower extremity chronic venous disease: initial results.

Chronic Venous Insufficiency (CVI) is not only detrimental to patients' Quality of Life (QoL) but also places a considerable burden on public health resources. Ultrasound guided foam sclerotherapy (USFS) is a good treatment option, but its effect on patients' QOL is still unclear. This article presents the results from the first 27 patients in a prospective, longitudinal, non-controlled study for evaluation of the clinical and QOL impact of USFS treatment for CEAP C4 to C6 grade CVI with contraindications for open surgery. Clinical symptoms were measured with the Venous Clinical Severity Score (VCSS) and QOL by the Assessment of Burden Chronic Disease - Venous questionnaire (ABC-V). We observed 22.2% reductions in VCSS (p<0.001) in the first week after the procedure, and a 37.8% reduction in ABC-V scores (p=0.03) over the first 3 months.

A new Chlorin formulation promotes efficient photodynamic action in choriocapillaris of rabbit's eyes.

Age-related macular degeneration (AMD) as well as other choroidal diseases, demand novel therapeutic methods. Photodynamic therapy (PDT), which uses light and photosensitizer (PS) to cause specific vascular occlusion in the macula, is an interesting alternative. The only drug approved for the PDT treatment of AMD (Verteporfin) has a natural tendency to aggregate, demanding an expensive separation procedure during purification. We report a novel and affordable PS that is intrinsically protected against aggregation, the Monomeric Chlorin at High Concentration (MCHC-Chlorin), whose liposomal formulation was developed to provoke effective photodynamic action on the choroidal vasculature. Our report starts by stablishing the conditions to allow the efficient synthesis of MCHC-Chlorin in high yields (92%). We then tested the light stimulated occlusion of choriocapillary vessels in rabbit's eyes induced by the two MCHC-Chlorin isomers, which are directly obtained from the synthetic route. The PS formulation was infused in the rabbit's ear vein and eyes were immediately irradiated at 650 nm. Indirect ophthalmoscopy, fundus photography, fluorescein angiography and histopathological evaluations were used to evaluate levels of photo-thrombosis and collateral damage. Choriocapillary occlusion was achieved in all treated rabbits' eyes, while retina and sclera were completely preserved. There was no photochemical reaction in none of the eyes that received LASER without PS. Both MCHC-Chlorin isomers were separately tested and exhibited similar positive results with no systemic toxicity. Therefore, PDT occurred equally well in all treated eyes and none of the controls showed any effect in the ophthalmological exams. MCHC-Chlorin offers great potential and should be further studied as an alternative drug for choroidal diseases.

Effects of myogenic precursor cells (C2C12) transplantation and low-level laser therapy on muscle repair.

OBJECTIVE: The aim of the present study was to evaluate the effects of myoblast inoculation in combination with photobiomodulation therapy (PBMT) on skeletal muscle tissue following injury. MATERIALS AND METHODS: Sixty-five Wistar rats were divided into five groups: Control-animals not submitted to any procedure; Injury-cryoinjury of the tibialis anterior muscle; HBSS-animals submitted to cryoinjury and intramuscular Hank's Balanced Salt Solution; Injury + Cells-animals submitted to cryoinjury, followed by myogenic precursor cells (C2C12) transplantation; Injury + Cells + LLLT-animals submitted to cryoinjury, followed by myogenic precursor cells (C2C12) transplantation and PBMT (780 nm, 40 mW, 3.2 J in 8 points). The periods analyzed were 1, 3, and 7 days. The tibialis anterior muscle was harvest for histological analysis, collagen analysis, and immunolabeling of macrophages. RESULTS: No differences were found between the HBSS group and injury group. The Injury + Cells group exhibited an increase of inflammatory cells and immature fibers as well as a decrease in the number of macrophages on Day 1. The Injury + Cells + LLLT group exhibited a decrease in myonecrosis and inflammatory infiltrate at 7 days, but an increase in inflammatory infiltrate at 1 and 3 days as well as an increase in blood vessels at 3 and 7 days, an increase in macrophages at 3 days and better collagen organization at 7 days. CONCLUSION: Cell transplantation combined with PBMT led to an increase in the number of blood vessels, a reduction in myonecrosis and total inflammatory cells as well as better organization of collagen fibers during the skeletal muscle repair process.

Influence of intraoperative findings on immediate flow through radial-cephalic arteriovenous wrist fistulas for hemodialysis access.

BACKGROUND: Adequate flow through a newly created arteriovenous fistula depends on multiple characteristics of the vessels and patient comorbidities. Several studies have related preoperative findings to failure, but few have analyzed the influence of intraoperative findings. OBJECTIVES: To evaluate the predictive value of intraoperative findings on the immediate outcome of radial-cephalic arteriovenous wrist fistulas (RCAVF) by collecting data that are easily measured intraoperatively. METHODS: We designed a cross-sectional study, in which a single surgeon performed 101 RCAVF in 100 patients at a single center. We analyzed the immediate postoperative flow, assessed by thrill intensity immediately after fistula creation, against patient demographics and intraoperative data. The following variables were analyzed: age, sex, comorbidities, length of vein visible at preoperative examination, macroscopic arterial calcification, maximum vein diameter, and length of stenosis-free vein, measured by cannulation with a urethral catheter during the procedure. The chi-square test was used both to eliminate possible bias introduced by side of venous access (left or right), and to determine predictive values of immediate thrill. RESULTS: Side of access was not associated with any significant differences in variables. Absence of macroscopic arterial calcification, successful venous catheterization using a 6 French catheter or larger, and ability to advance it more than 10 centimeters along the lumen of the proximal vein were correlated with adequate immediate postoperative thrill (p = 0.004, p < 0.001, and p = 0.005, respectively). CONCLUSIONS: In this series of 101 RCAVF, both the diameter of the catheter and its progress through the proximal vein and also absence of arterial calcification had positive predictive value for achieving adequate immediate thrill after vascular access construction.

CONTEXTO: O fluxo adequado de uma fístula arteriovenosa recém-confeccionada depende de múltiplas características dos vasos, bem como de comorbidades do paciente. Diversos estudos associam achados pré-operatórios e suas relações à falha do acesso, mas poucos analisam a influência dos achados encontrados no intraoperatório. OBJETIVOS: Avaliar o valor preditivo desses achados no fluxo imediato de fístulas arteriovenosas radiocefálicas de punho (FAVRCPs) para hemodiálise através de coleta de dados facilmente mensuráveis do intraoperatório. MÉTODOS: Um único cirurgião realizou 101 FAVRCPs em 100 pacientes, em um único centro. Analisou-se o fluxo do pós-operatório imediato através da intensidade do frêmito imediatamente após a confecção do acesso, e os resultados foram comparados com dados demográficos e achados intraoperatórios. As variáveis analisadas foram sexo, idade, comorbidades, extensão da veia visível ao exame físico, presença de calcificação arterial macroscópica, diâmetro venoso máximo e extensão de veia livre de estenose, avaliadas através da cateterização venosa com sonda uretral durante o procedimento. O teste de qui-quadrado foi utilizado tanto para excluir um possível viés de confusão pelo lado do acesso como para avaliar o valor preditivo das variáveis na intensidade do frêmito. RESULTADOS: Não foi identificada diferença significativa nas variáveis segundo o lado do acesso. A ausência de calcificação arterial, a possibilidade de cateterização venosa com sonda de 6 French ou maior, e a sua progressão por mais de 10 cm através do lúmen da veia proximal tiveram correlação com frêmito imediato adequado ao fim do procedimento (p = 0,004, p < 0,001 e p = 0,005, respectivamente). CONCLUSÕES: Nesta série de 101 FAVRCPs, o diâmetro e a progressão de cateter 6 French ou maior através da veia proximal e a ausência de calcificação arterial apresentaram valor preditivo positivo na obtenção de frêmito imediato adequado de FAVRCP para hemodiálise.

Immediate effect of transcranial direct current stimulation combined with functional electrical stimulation on activity of the tibialis anterior muscle and balance of individuals with hemiparesis stemming from a stroke.

[Purpose] The aim of the present study was to evaluate the immediate effects of transcranial direct current stimulation (tDCS) and functional electrical stimulation (FES) on activity of the tibialis anterior muscle (TA) and static balance of individuals with hemiparesis stemming from stroke. [Subjects and Methods] A randomized, double-blind, crossover, clinical trial conducted with 30 individuals with chronic post-stroke hemiparesis. Median frequency of electrical activity of the TA were determined using electromyography in five contractions concentrics and Static balance (body sway velocity and frequency), both before and immediately after the intervention. The participants were submitted to four 20-minute intervention protocols with 48-hour interval: anodal tDCS + sham FES; sham tDCS + active FES; anodal tDCS + active FES and sham tDCS + sham FES. Anodal tDCS was administered over C3 or C4, the cathode was positioned in the supraorbital region on the contralateral side and FES was administered to the affected TA. [Results] No significant differences among the protocols were found regarding electrical activity of the TA and static balance. [Conclusion] The results demonstrate that tDCS alone or in combination with FES had no immediate effect on electrical activity of the TA and static balance of the 30 individuals analyzed.

Chlorophyllin-M: A new substance for photodynamic therapy in the retina and choroid.

BACKGROUND AND OBJECTIVE: Chlorophyllin-M is a new chlorophyll-based derivative photosensitive compound developed by our research group with easy laboratorial synthesis and ideal properties for photodynamic therapy (PDT). It is intended for clinical treatments with simple and low cost techniques and reagents. The objective of this study is to evaluate if intravenous chlorophyllin-M is able to deliver a photosensitizer to rabbit retina and rabbit choroid and promote PDT after ocular irradiation with a 660 nm LASER. METHODS: This is a pre-clinical study. Ten eyes of five pigmented Californian rabbits were included in the study. The right eyes served as the treatment group, and the left eyes served as the control group. All eyes had been ophthalmologically evaluated and were considered normal. RESULTS: Ophthalmic exam with anterior biomicroscopy, dilated fundus examination, and fluorescein angiography after the LASER procedure revealed normal anterior segment, retinal and choroid vessels occlusion, lumen narrowing, and capillary non-perfusion in the treated areas, indicating that PDT was successful in the treatment eyes group. CONCLUSION: The results of this pre-clinical study encourage future studies with this new compound. Chlorophyllin-M may become a new cost-effective agent in the retinal therapeutic arsenal.

Psychometric properties of the stroke specific quality of life scale for the assessment of participation in stroke survivors using the rasch model: a preliminary study.

[Purpose] The aim of the present study was to analyze the psychometric properties of the Stroke Specific Quality of Life (SS-QOL) scale for the assessment of social participation following a stroke. [Methods] A preliminary analysis was performed of the SS-QOL items that address the participation category. For this, the scoring patterns of the answers of individuals and internal consistence were determined using the Rasch model. Reliability was assessed by intraclass correlation coefficients (ICC). [Results] The reliability coefficients analyzed by the Rasch model were 0.91 for the items and 0.87 for the patients. The separation index was 3.19 for the items and 2.58 for the patients. The findings indicate that the items separated the patients into three levels of participation: low, medium, and high. Among the 26 items addressing participation, three did not fit the model. All items showed adequate reliability (ICC ≥ 0.60). [Conclusion] The Rasch analysis detected three items with erratic behavior; however, the erratic patterns of these items may be explained by individual peculiarities among the patients. These items should be monitored to determine if the problems found in the present study persist. If so, the items should also be revised or possibly even eliminated.

Evaluation of post-stroke functionality based on the International Classification of Functioning, Disability, and Health: a proposal for use of assessment tools.

This study aimed to identify the International Classification of Functioning, Disability, and Health categories addressed by the assessment tools commonly used in post-stroke rehabilitation and characterize patients based on its evaluation model. [Subjects and Methods] An exploratory, descriptive, cross-sectional study was conducted involving 35 individuals with chronic post-stroke hemiparesis. Handgrip strength was assessed to evaluate body functions and structures. The 10-meter gait speed test and Timed Up and Go test were administered to evaluate activity. The Stroke Specific Quality of Life scale was used to evaluate participation. Moreover, a systematic review of the literature was performed to identify studies that have associated these assessment tools with the International Classification of Functioning, Disability, and Health categories. [Results] The tools employed in this study for evaluating function addressed 63 International Classification of Functioning, Disability, and Health categories: 24 related to body functions and structures; 36 related to activity and participation; and 3 related to environmental factors. [Conclusion] The assessment tools employed in this study addressed 63 International Classification of Functioning, Disability, and Health categories and allowed a more complete evaluation of stroke survivors with hemiparesis. Use of this classification can therefore be more easily incorporated into clinical practice.

Endovascular treatment of a giant hepatic artery aneurysm with Amplatzer vascular plug.

Hepatic artery aneurysms are uncommon and account for 20% of visceral aneurysms. Some authors consider endovascular procedures as the first line treatment for most hepatic artery aneurysms, being the conventional surgery reserved for unstable ruptured aneurysms or if the anatomy is unsuitable for endovascular repair. In this report, we describe the endovascular treatment of a giant common hepatic artery aneurysm with an Amplatzer vascular plug.
