Cryo-SOFI enabling low-dose super-resolution correlative light and electron cryo-microscopy.

Correlative light and electron cryo-microscopy (cryo-CLEM) combines information from the specific labeling of fluorescence cryo-microscopy (cryo-FM) with the high resolution in environmental context of electron cryo-microscopy (cryo-EM). Exploiting super-resolution methods for cryo-FM is advantageous, as it enables the identification of rare events within the environmental background of cryo-EM at a sensitivity and resolution beyond that of conventional methods. However, due to the need for relatively high laser intensities, current super-resolution cryo-CLEM methods require cryo-protectants or support films which can severely reduce image quality in cryo-EM and are not compatible with many samples, such as mammalian cells. Here, we introduce cryogenic super-resolution optical fluctuation imaging (cryo-SOFI), a low-dose super-resolution imaging scheme based on the SOFI principle. As cryo-SOFI does not require special sample preparation, it is fully compatible with conventional cryo-EM specimens, and importantly, it does not affect the quality of cryo-EM imaging. By applying cryo-SOFI to a variety of biological application examples, we demonstrate resolutions up to ∼135 nm, an improvement of up to three times compared with conventional cryo-FM, while maintaining the specimen in a vitrified state for subsequent cryo-EM. Cryo-SOFI presents a general solution to the problem of specimen devitrification in super-resolution cryo-CLEM. It does not require a complex optical setup and can easily be implemented in any existing cryo-FM system.

Efficacy of a Homeopathic Medicine of Capsicum frutescens L. (Solanaceae) in the Treatment of Hot Flashes in Menopausal Women: A Phase-2 Randomized Controlled Trial.

BACKGROUND: Hot flashes are common in women during menopause, and are an important cause of discomfort, increasing the number of medical appointments. Hormone replacement therapy is an effective treatment, but it can bring undesirable consequences. Alternative treatments exist but they are not universally accepted or effective. The ingestion of malagueta peppers (popular name for fruits of Capsicum frutescens L., Solanaceae) causes sensations similar to those experienced by women during hot flashes. Using the homeopathic law of similars (let like be cured by like), we hypothesized that a homeopathic remedy made of malagueta peppers can be effective in alleviating menopausal hot flashes. We named this remedy Malagueta. METHODS: This randomized, placebo-controlled, double-blind, phase-2 clinical trial was designed to test the hypothesis that, in menopausal women, the homeopathic medicine Malagueta (30 CH), compared with placebo, will significantly reduce the intensity of hot flashes, after 4 weeks of treatment. The primary outcome was the intensity of hot flashes, measured by the Measure Yourself Medical Outcome Profile (MYMOP) instrument. A total of 40 women were enrolled in the study, 20 in each group. RESULTS: The effect of Malagueta on the primary outcome, the intensity of hot flashes, assessed by MYMOP, was superior to that of placebo over the 4 weeks of treatment, with worsening in both groups after treatment was interrupted (after week 4, p < 0.001 in ordinal logistic regression). The odds ratio for treatment response (reduction of at least three MYMOP categories) was 2.78 (95% confidence interval, 0.77 to 10.05). Treatment with Malagueta, compared with placebo, also reduced the intensity of the secondary symptoms (p = 0.001) and improved level of activity (p = 0.025) and well-being (p = 0.008). CONCLUSION: The homeopathic medicine of Capsicum frutescens (Malagueta) was superior to placebo in reducing the intensity of hot flashes in menopausal women after 4 weeks of treatment.

Convergence of lateral dynamic measurements in the plasma membrane of live cells from single particle tracking and STED-FCS.

Fluorescence correlation spectroscopy (FCS) in combination with the super-resolution imaging method STED (STED-FCS), and single-particle tracking (SPT) are able to directly probe the lateral dynamics of lipids and proteins in the plasma membrane of live cells at spatial scales much below the diffraction limit of conventional microscopy. However, a major disparity in interpretation of data from SPT and STED-FCS remains, namely the proposed existence of a very fast (unhindered) lateral diffusion coefficient, ⩾5 µm2 s-1, in the plasma membrane of live cells at very short length scales, ≈⩽ 100 nm, and time scales, ≈1-10 ms. This fast diffusion coefficient has been advocated in several high-speed SPT studies, for lipids and membrane proteins alike, but the equivalent has not been detected in STED-FCS measurements. Resolving this ambiguity is important because the assessment of membrane dynamics currently relies heavily on SPT for the determination of heterogeneous diffusion. A possible systematic error in this approach would thus have vast implications in this field. To address this, we have re-visited the analysis procedure for SPT data with an emphasis on the measurement errors and the effect that these errors have on the measurement outputs. We subsequently demonstrate that STED-FCS and SPT data, following careful consideration of the experimental errors of the SPT data, converge to a common interpretation which for the case of a diffusing phospholipid analogue in the plasma membrane of live mouse embryo fibroblasts results in an unhindered, intra-compartment, diffusion coefficient of ≈0.7-1.0 µm2 s-1, and a compartment size of about 100-150 nm.

Reorganization of Lipid Diffusion by Myelin Basic Protein as Revealed by STED Nanoscopy.

Myelin is a multilayered membrane that ensheathes axonal fibers in the vertebrate nervous system, allowing fast propagation of nerve action potentials. It contains densely packed lipids, lacks an actin-based cytocortex, and requires myelin basic protein (MBP) as its major structural component. This protein is the basic constituent of the proteinaceous meshwork that is localized between adjacent cytoplasmic membranes of the myelin sheath. Yet, it is not clear how MBP influences the organization and dynamics of the lipid constituents of myelin. Here, we used optical stimulated emission depletion super-resolution microscopy in combination with fluorescence correlation spectroscopy to assess the characteristics of diffusion of different fluorescent lipid analogs in myelin membrane sheets of cultured oligodendrocytes and in micrometer-sized domains that were induced by MBP in live epithelial PtK2 cells. Lipid diffusion was significantly faster and less anomalous both in oligodendrocytes and inside the MBP-rich domains of PtK2 cells compared with undisturbed live PtK2 cells. Our data show that MBP reorganizes lipid diffusion, possibly by preventing the buildup of an actin-based cytocortex and by preventing most membrane proteins from entering the myelin sheath region. Yet, in contrast to myelin sheets in oligodendrocytes, the MBP-induced domains in epithelial PtK2 cells demonstrate no change in lipid order, indicating that segregation of long-chain lipids into myelin sheets is a process specific to oligodendrocytes.

The efficacy of Raf kinase recruitment to the GTPase H-ras depends on H-ras membrane conformer-specific nanoclustering.

Solution structures and biochemical data have provided a wealth of mechanistic insight into Ras GTPases. However, information on how much the membrane organization of these lipid-modified proteins impacts on their signaling is still scarce. Ras proteins are organized into membrane nanoclusters, which are necessary for Ras-MAPK signaling. Using quantitative conventional and super-resolution fluorescence methods, as well as mathematical modeling, we investigated nanoclustering of H-ras helix α4 and hypervariable region mutants that have different bona fide conformations on the membrane. By following the emergence of conformer-specific nanoclusters in the plasma membrane of mammalian cells, we found that conformers impart distinct nanoclustering responses depending on the cytoplasmic levels of the nanocluster scaffold galectin-1. Computational modeling revealed that complexes containing H-ras conformers and galectin-1 affect both the number and lifetime of nanoclusters and thus determine the specific Raf effector recruitment. Our results show that mutations in Ras can affect its nanoclustering response and thus allosterically effector recruitment and downstream signaling. We postulate that cancer- and developmental disease-linked mutations that are associated with the Ras membrane conformation may exhibit so far unrecognized Ras nanoclustering and therefore signaling alterations.

Environmental Comfort in Promoting Sleep in Critically Ill Patients: A Scoping Review.

INTRODUCTION: It is important to understand the concept of comfort as a whole to build an assistance intervention plan that meets the person's needs. Therefore, it is necessary to monitor and assess the person's sleep by considering the surrounding environment, to provide a comfortable environment that is quiet and provides privacy, especially in contexts of difficult management of environmental factors in the approach to the person in critical condition. OBJECTIVES: The aims of this study were to map the nursing interventions that promote sleep-promoting environmental comfort in critically ill people and identify the instruments to assess sleep in critically ill people. METHODS: This is a scoping review based on the methodological strategy of the Joanna Briggs Institute for Scoping Reviews. The search was conducted on February 17 and 18, 2022, in the databases CINAHL, Cochrane Library Plus, PubMed, JBI Evidence Synthesis, SciELO, DANS Easy Archive, RCAAP, and DART-Europe using the Boolean phrase search strategy: "Hospital Emergency Service" OR "Critical Care" AND "Sleep" NOT "Children" AND Nurs*. We included all studies, conducted in any contextual setting, in Portuguese, English, or Spanish, on adult patients with acute and/or critical illness in intensive care and/or emergency units, which addressed nursing interventions that contribute to environmental comfort and promote sleep. Studies on pregnant or puerperal women, persons with psychiatric disorders, and those at the end of life or in palliative care were excluded. RESULTS: Twenty-one articles were included in this scoping review. Three categories of nursing interventions emerged: person centered (14 interventions), environment centered (37 interventions), and nurse role centered (45 interventions). Three categories of instruments for sleep assessment emerged, in particular: quality of sleep (12 instruments), environmental effects on a night's sleep (2 instruments), and influence on sleep practices in the intensive care unit (1 instrument). DISCUSSION: The use of instruments to monitor comfort and sleep allows for an accurate assessment of the impact of nurses' intervention focusing on sleep-promoting interventions aimed at comfort, for an improvement of sleep in critically ill patients. CONCLUSION: The interpretation of the content makes it clear that how critically ill patients in different contexts experience the environmental context positively or negatively conditions their comfort. In this sense, it is essential to reflect on these measures as a team so that everyone can apply them.

otpb functions in a Lef1-dependent transcriptional network required for expression of the stress response inhibitor crhbp in the zebrafish hypothalamus.

The vertebrate hypothalamus regulates physiological and behavioral responses to environmental stimuli through the function of evolutionarily-conserved neuronal subpopulations. Our previous work found that mutation of zebrafish lef1 , which encodes a transcriptional mediator of the Wnt signaling pathway, leads to the loss of hypothalamic neurons and behavioral phenotypes that are both associated with stress-related human mood disorders However, the specific Lef1 target genes that link neurogenesis to behavior remain unknown. One candidate is otpb , which encodes a transcription factor with known roles in hypothalamic development. Here we show that otpb expression in the posterior hypothalamus is Lef1-dependent, and that like lef1 , its function is required for the generation of crhbp + neurons in this region. Transgenic reporter analysis of a crhbp conserved noncoding element suggests that otpb participates in a transcriptional regulatory network with other Lef1 targets. Finally, consistent with a role for crhbp in inhibiting the stress response, zebrafish otpb mutants exhibit decreased exploration in a novel tank diving assay. Together our findings suggest a potential evolutionarily-conserved mechanism for the regulation of innate stress response behaviors through Lef1-mediated hypothalamic neurogenesis.

The Effectiveness of Topical Dimethicone Together with a One Health Approach for the Control of Tungiasis in the Sanumás Communities, Yanomami Territory, Amazon Rainforest: A Real-World Study.

BACKGROUND: The success of tungiasis treatment is highly dependent on adequate environmental control. METHODS: This is a real-world observational cohort study designed to monitor the effectiveness of topical dimethicone together with a One Health approach for the control of tungiasis in the Sanumás communities, Amazon rainforest, Brazil. We followed up on 562 indigenous people and 81 domestic dogs for 1.5 years in a 3-month interval. A new molecular method for large-scale soil evaluation was also tested. The control of tungiasis was independently conducted by the Brazilian Ministry of Health and comprised topical dimethicone application (NYDA®) for humans, single-dose oral afoxolaner for dogs, and in-house soil fumigation with fipronil. The main outcome was the occurrence of tungiasis after the use of topical dimethicone together with the One Health approach. RESULTS: A total of 49 of the 562 indigenous people had active tungiasis at enrollment (8.72%). Only three cases of tungiasis resulted in active lesions after the use of topical dimethicone together with the One Health approach, with two cases of recurrence. From the 6-month follow-up and after, soil infestation was not detected. CONCLUSIONS: We conclude that the use of NYDA® together with animal and environmental interventions are effective measures for the control of tungiasis.

Semysinthetic biflavonoid Morelloflavone-7,4',7″,3‴,4‴-penta-O-butanoyl is a more potent inhibitor of Proprotein Convertases Subtilisin/Kexin PC1/3 than Kex2 and Furin.

BACKGROUND: Garcinia brasiliensis is a species native to the Amazon forest. The white mucilaginous pulp is used in folk medicine as a wound healing agent and for peptic ulcer, urinary, and tumor disease treatments. The activity of the proprotein convertases (PCs) Subtilisin/Kex is associated with the development of viral, bacterial and fungal infections, osteoporosis, hyperglycemia, atherosclerosis, cardiovascular, neurodegenerative and neoplastic diseases. METHODS: Morelloflavone (BF1) and semisynthetic biflavonoid (BF2, 3 and 4) from Garcinia brasiliensis were tested as inhibitor of PCs Kex2, PC1/3 and Furin, and determined IC50, Ki, human proinflammatory cytokines secretion in Caco-2 cells, mechanism of inhibition, and performed molecular docking studies. RESULTS: Biflavonoids were more effective in the inhibition of neuroendocrine PC1/3 than mammalian Furin and fungal Kex2. BF1 presented a mixed inhibition mechanism for Kex2 and PC1, and competitive inhibition for Furin. BF4 has no good interaction with Kex2 and Furin since carboxypropyl groups results in steric hindrance to ligand-protein interactions. Carboxypropyl groups of BF4 promote steric hindrance with Kex2 and Furin, but effective in the affinity of PC1/3. BF4 was more efficient at inhibiting PCl/3 (IC50 = 1.13 µM and Ki = 0,59 µM, simple linear competitive mechanism of inhibition) than Kex2, Furin. Also, our results strongly suggested that BF4 also inhibits the endogenous cellular PC1/3 activity in Caco-2 cells, since PC1/3 inhibition by BF4 causes a large increase in IL-8 and IL-1ß secretion in Caco-2 cells. CONCLUSIONS: BF4 is a potent and selective inhibitor of PC1/3. GENERAL SIGNIFICANCE: BF4 is the best candidate for further clinical studies on inhibition of PC1/3.

Dating Applications, Sexual Behaviors, and Attitudes of College Students in Brazil's Legal Amazon.

Although dating applications (apps) have become popular among young adults, there is a dearth of information regarding the sexual health implications among Brazilian college students. This study examined risky sexual behavior and attitudes of dating app users, based on their sex in Brazil's Legal Amazon. Three hundred and fifty-nine students reported their sociodemographic data, dating app use, and sexual behaviors and attitudes through self-administered questionnaires. Bivariate analyses and analysis of variance (ANOVA) with Bonferroni post-hoc tests were performed. Dating app use was reported by 238 (66.3%) subjects, most of whom had an encounter and sex with a casual partner. Women frequently requested condom use. Trust in one's partner or having repeated encounters were the main reasons for engaging in risky sexual behavior. Men had a greater number of sexual partners and less protective attitudes. Sexual health awareness by apps was not reported by 97% of women, and most of them were not tested for sexually transmitted infections. A positive attitude toward sexual health was not a predictor of safe sex. Important similarities and differences regarding risky sexual behaviors and attitudes were observed between the sexes, many of which correlated with increased sexual vulnerability during the sexual encounters arranged through the dating apps. This cross-sectional study supports efforts on sexual health promotion and sexual education implementation in the face of growing usage of apps among young adults for sexual matters.

Chemical Composition, Toxicity, Antinociceptive, and Anti-Inflammatory Activity of Dry Aqueous Extract of Varronia multispicata (Cham.) Borhidi (Cordiaceae) Leaves.

Varronia multispicata (Cham.) Borhidi (Cordiaceae), an herbaceous plant distributed in tropical and subtropical regions is native of Brazil and widely used in folk medicine to treat respiratory and digestive diseases, inflammation, and some types of infections. Thus, this study aimed to investigate acute oral toxicity, antinociceptive, and anti-inflammatory activities of dry aqueous extract of V. multispicata (AEVm) and to identify its compounds. Extract was obtained by lyophilized leaf infusion and its composition was analyzed by ultra-performance liquid chromatography-high resolution mass spectrometry (LC-MS). Acute oral toxicity was evaluated in female rats treated with AEVm (2,000 mg/kg) in a single oral dose. Mortality, body weight changes, feed and water intake, organ weights, histological and biochemical parameters were screened for 14 days. Antinociceptive activity was evaluated by writhing (WT), formalin (FT), and hot plate (HP) tests in male mice while anti-inflammatory activity was performed by carrageenan (CPE) and dextran (DPE)-induced paw edema tests and carrageenan-induced peritonitis (CP) test in male rats. Additionally, spontaneous open-field (OF) locomotion was evaluated. LC-MS analysis revealed the presence of flavonoids with biological activity. In toxicity evaluation, extract did not cause deaths in dose of 2,000 mg/kg, and there were no significant behavioral or biochemical alterations. Additionally, evidence of hepatoprotective and antioxidant activity was observed. In pharmacological evaluation AEVm showed dose-dependent antinociceptive activity in WT, with a median effective dose of 146.89 mg/kg, which showed selectivity by inflammatory base processes (FT first phase; p < 0.001), showing no activity in neuropathic nociception components (FT second phase and HP) or about consciousness and locomotion in OF. AEVm also showed significant anti-inflammatory activity, inhibiting CPE (p < 0.001) and cell migration (p < 0.05) and nitric oxide (NO) production (p < 0,01) in CP test. These data demonstrate that AEVm has low oral toxicity-with evidence of hepatoprotective and antioxidant properties-antinociceptive and anti-inflammatory activity, supporting V. multispicata traditional use, possibly related to flavonoids present in its constitution.

The use of bisphosphonate in the treatment of avascular necrosis: a systematic review.

Up to now, there is no uniformly accepted treatment for avascular necrosis (AN) that alleviates pain and retards its progression. The aim of clinical and surgical treatments is usually only to improve blood support in the avascular area. The objective of the present study was to make a systematic review of the use of bisphosphonates in the treatment of AN. Studies in which bisphosphonate was used for the treatment of AN were researched through the MEDLINE databases (from 1966 to 2007) and the Cochrane Central Register of Controlled Trials and using the following terms: "avascular necrosis," "aseptic necrosis," "bisphosphonates," "alendronate," "pamidronate," "zoledronate," and "risedronate". Only seven articles that met the previously established criteria were obtained from MEDLINE, and none were obtained from the Cochrane Central Register of Controlled Trials. Of these seven articles, two were randomized clinical trials and five were prospective comparative studies; one of them corresponded to an extension of a previous study. The present review demonstrates that there are no controlled and double-blind studies about the efficacy of bisphosphonates in the treatment of AN. Therefore, the data are still insufficient for justifying its use for this indication. On the other hand, noncontrolled studies appear to demonstrate favorable results, particularly in diminishing pain, improving mobility, and lowering the incidence of articular collapse, which justifies new studies being developed in this area.

Research Priorities and Resource Allocation in the Investigation of New Drugs for Cancer in Least Developed Countries.

Cancer incidence has increased significantly in low- and middle-income countries. The priorities of international health research are not always aligned with the global burden of cancer. This study aims to analyze global tendencies in clinical trials in oncology and discuss research priorities and resource allocation in the investigation of new drugs for cancers that significantly affect the least developed countries. This was a retrospective and analytical study that included data collected from the World Health Organization's International Clinical Trials Registry Platform (ICTRP) in 2014. According to our results, there was a tendency for clinical trials involving breast and lung cancer to be conducted in countries with a lower level of economic development. On the other hand, cervical, stomach, and liver cancer, despite the significant burden that these place on middle- and low-income countries, were studied little among the countries selected. In conclusion, the organizations that most fund research to develop new drugs for cancer treatment continue to show little interest in prioritizing resources to fund research for certain types of cancer such as those of the cervix, stomach, and liver, which have a significant impact in low- and middle-income countries.

Recursos audiovisuais como ferramenta de ensino da segurança do paciente: uma revisão integrativa da literatura

Resumo Objetivo: Apresentar resultados de uma revisão integrativa da literatura nacional e internacional sobre o uso de tecnologias educacionais com mídias audiovisuais para o ensino da segurança do paciente. Fonte de dados: Foram analisados artigos publicados de 2010 a 2020 a partir da seleção nas bases de dados da Literatura Latino-americana e do Caribe em Ciências da Saúde (Lilacs) via Biblioteca Virtual de Saúde, Medline via PubMed-NCBI, Scopus e a CINAHL. Resumo das conclusões: A amostra final foi composta de oito estudos. Foram identificadas três modalidades de tecnologias educacionais audiovisuais. Se apropriar destas ferramentas no ensino da Segurança do Paciente, com uso de cenários, por exemplo, onde o indivíduo se enxerga como parte de um todo, tornar-se-ia uma oportunidade de qualificar os profissionais e estudantes da saúde, e quiçá fomentar uma assistência mais segura, reduzindo a cultura punitiva ainda presente e melhorando a comunicação efetiva entre a equipe multidisciplinar.

Inflammatory pseudotumor: A diagnostic dilemma.

Inflammatory pseudotumor (IP) is a disorder that constitutes a differential diagnosis of a series of clinical conditions due to a large spectrum of manifestations in presentation since it can involve any organ of the human body. Its basic characteristic is the appearance of inflammatory masses whose symptoms depend on their location. We describe two cases of IP that clearly illustrate this diversity of presentation and we review the diagnostic and therapeutic strategies for such a condition.

Aberrations and adaptive optics in super-resolution microscopy.

As one of the most powerful tools in the biological investigation of cellular structures and dynamic processes, fluorescence microscopy has undergone extraordinary developments in the past decades. The advent of super-resolution techniques has enabled fluorescence microscopy - or rather nanoscopy - to achieve nanoscale resolution in living specimens and unravelled the interior of cells with unprecedented detail. The methods employed in this expanding field of microscopy, however, are especially prone to the detrimental effects of optical aberrations. In this review, we discuss how super-resolution microscopy techniques based upon single-molecule switching, stimulated emission depletion and structured illumination each suffer from aberrations in different ways that are dependent upon intrinsic technical aspects. We discuss the use of adaptive optics as an effective means to overcome this problem.

Cortical actin networks induce spatio-temporal confinement of phospholipids in the plasma membrane--a minimally invasive investigation by STED-FCS.

Important discoveries in the last decades have changed our view of the plasma membrane organisation. Specifically, the cortical cytoskeleton has emerged as a key modulator of the lateral diffusion of membrane proteins. Cytoskeleton-dependent compartmentalised lipid diffusion has been proposed, but this concept remains controversial because this phenomenon has thus far only been observed with artefact-prone probes in combination with a single technique: single particle tracking. In this paper, we report the first direct observation of compartmentalised phospholipid diffusion in the plasma membrane of living cells using a minimally invasive, fluorescent dye labelled lipid analogue. These observations were made using optical STED nanoscopy in combination with fluorescence correlation spectroscopy (STED-FCS), a technique which allows the study of membrane dynamics on a sub-millisecond time-scale and with a spatial resolution of down to 40 nm. Specifically, we find that compartmentalised phospholipid diffusion depends on the cortical actin cytoskeleton, and that this constrained diffusion is directly dependent on the F-actin branching nucleator Arp2/3. These findings provide solid evidence that the Arp2/3-dependent cortical actin cytoskeleton plays a pivotal role in the dynamic organisation of the plasma membrane, potentially regulating fundamental cellular processes.

Antibodies to Schistosoma mansoni in human cerebrospinal fluid.

Cerebrospinal fluid (CSF) and serum samples from patients suspected of having neuroschistosomiasis (NS) were evaluated by an enzyme-linked immunosorbent assay. Monoclonal antibodies of various immunoglobulin isotypes (IgM, IgA, IgE, total IgG, IgG1, IgG2, IgG3, and IgG4) were used to detect antibodies against Schistosoma mansoni soluble egg antigen (SEA) and soluble worm adult preparation (SWAP). Of the 83 CSF samples tested, 55% were reactive to SEA (26% were reactive only to SEA and 29% to both SEA and SWAP), 34% were reactive to SWAP (5% only to SWAP and 29% to both SEA and SWAP), and 40% were not reactive with any antigen. Cases that tested positive for SWAP in CSF and negative in serum were not found. Samples with high specific IgG antibody titers were selected for immunoglobulin isotype profiling. In the CSF samples, the antibodies against SEA and SWAP were mainly IgM, IgG1, and IgG4, although other immunoglobulins were also detected. Interestingly, nine patients had high levels of IgG1 only in the CSF. These results suggest that there is local synthesis of IgG1, and that this isotype could be an important immunologic marker in the diagnosis of NS.
