    Abstract The aim of this study was to investigate the production, stability and applicability of colorants produced by filamentous fungi isolated from soil samples from the Amazon. Initially, the isolates were evaluated in a screening for the production of colorants. The influences of cultivation and nutritional conditions on the production of colorants by fungal isolates were investigated. The colorants produced by selected fungal isolates were chemically characterized using the Liquid Chromatography-Mass Spectrometry technique. The antimicrobial and cytotoxic activities, stability evaluation and applicability of the colorants were investigated. As results, we observed that the isolates Penicillium sclerotiorum P3SO224, Clonostachys rosea P2SO329 and Penicillium gravinicasei P3SO332 stood out since they produced the most intense colorants. Compounds produced by Penicillium sclerotiorum P3SO224 and Clonostachys rosea P2SO329 were identified as sclerotiorin and penicillic acid. The colorant fraction (EtOAc) produced by these species has antimicrobial activity, stability at temperature and at different pHs, stability when exposure to light and UV, and when exposed to different concentrations of salts, as well as being nontoxic and having the ability to dye fabrics and be used as a pigment in creams and soap. Considering the results found in this study, it was concluded that fungi from the soil in the Amazon have the potential to produce colorants with applications in the textile and pharmaceutical industries.

    Abstract We have developed an efficient chalcogenylation of electron-rich naphthalene derivatives catalyzed by FeCl 3 and KI. The methodology provides access to several nonsymmetrical diorganoyl chalcogenides (S, Se) by selective C1 chalcogenylation of 2-naphthols or 2-naphthylamines using simple and cheap catalysts. Several control experiments supported the hypothesis that a redox reaction between Fe(III) and KI produces I 2, which catalyzed the chalcogenylation.

    Abstract Viral hemorrhagic fevers (VHFs) are diseases caused by the RNA virus from 4 different families (Flaviridiae, Arenaviridae, Bunyaviridae, and Filoviridae) that are acquired through the bite of an infected arthropod or by the inhalation of particles of rodent excreta. Among the VHFs, dengue and yellow fever are the most prevalent in tropical regions worldwide. The clinical presentation is characterized by fever, malaise, increased vascular permeability, and coagulation defects that can result in bleeding. Acute kidney injury is an uncommon complication but renal dysfunction has been associated with various VHFs. In this article we review the renal manifestations of dengue and yellow fever infections.

    Abstract Secondary metabolites from natural products are a potential source of acetylcholinesterase inhibitors (AChEIs), which is a key enzyme in the treatment of many neurodegenerative diseases. Inspired by the reported activities of isoquinoline-derivative alkaloids herein we report the design, one step synthesis and evaluation by capillary enzyme reactor (ICER) of benzyl analogs (1a–1e) of the tetrahydroprotoberberine alkaloid stepholidine, which is abundant in Onychopetalum amazonicum. Docking analysis based on the crystal structure of Torpedo californica AChE (TcAChE) indicated that π-π interactions were dominant in all planned derivatives and that the residues from esteratic, anionic and peripheral subsites of the enzyme played key interaction roles. Due to the similarities observed when compared with galantamine in the AChE complex, the results suggest that ligand-target interactions would increase, especially for the N-benzyl derivatives. From a series of synthesized compounds, the alkaloids (7R,13aS)-7-benzylstepholidine (1a), (7S,13aS)-7-benzylstepholidine (1b), and (S)-10-O-benzylstepholidine (1d) are reported here for the first time. The on flow bioaffinity chromatography inhibition assay, based on the quantification of choline, revealed the N-benzylated compound 1a and its epimer 1b to be the most active, with IC50 of 40.6 ± 1 and 51.9 ± 1 μM, respectively, and a non-competitive mechanism. The proposed approach, which is based on molecular docking and bioaffinity chromatography, demonstrated the usefulness of stepholidine as a template for the design of rational AChEIs and showed how the target-alkaloid derivatives interact with AChE.

    Abstract Objectives: This study evaluated the effects of a protocol aiming to reduce hypotension in acute kidney injury (AKI) patients submitted to sustained low-efficiency dialysis (SLED).
    Methods: Patients were randomly assigned to two SLED prescriptions-control group, dialysate temperature was 37.0°C with a fixed sodium concentration [138 mEq/L] and ultrafiltration (UF) rate; and profiling group, dialysate temperature was 35.5°C with a variable sodium concentration [150-138 mEq/L] and UF rate.
    Results: Sixty-two SLED sessions were evaluated (34 in profiling and 28 in control). Patients (n = 31) were similar in terms of gender, age, and Sequential Organ Failure Assessment (SOFA) score. Dialysis time, dialysis dose, and post-dialysis serum sodium were similar in both groups. The profiling group had significantly less hypotension episodes (23% vs. 57% in control, p = 0.009) and achieved higher UF volume (2.23 ± 1.25 L vs. 1.59 ± 1.03 L in control, p = 0.04) when compared with control group.
    Conclusions: SLED protocol with modulation of dialysate temperature, sodium, and UF profiling showed similar efficacy but less intradialytic hypotension when compared with a standard SLED prescription.

    Abstract A 48-year-old renal transplant recipient who developed tetanus 6 years after transplantation is described. His immunosuppressive protocol was mofetil mycophenolate, sirolimus, and prednisone. The patient presented symptoms of severe tetanus with autonomic dysfunction, requiring ICU care and mechanical ventilation. His clinical course was marked by development of tetanus-induced acute kidney injury and sepsis. He was discharged after 37 days of hospitalization with recovered renal function. Tetanus is a preventable disease associated with a high fatality rate. Its treatment is difficult and requires specialized and intensive care. This case highlights the crucial importance of following adequate immunization guidelines in transplant recipients.

    Abstract Objective: To assess the role of insulin-like growth factor-1 and cholesterol as predictors of acute kidney injury mortality in intensive care unit patients.
    Design: Prospective cohort study.
    Setting: Multidisciplinary adult intensive care unit (24 beds).
    Patients: Adult patients with acute kidney injury at intensive care unit admission for an 11-month period were considered and a total of 56 patients were admitted in the study.
    Interventions: None.
    Measurements and main results: At intensive care unit admission serum insulin-like growth factor-1 (ng/mL), total cholesterol (mg/dL), albumin (g/dL), transferrin (mg/dL), total lymphocyte count, triceps skinfold thickness, arm muscle area, and Subjective Global Nutritional Assessment were evaluated. Insulin-like growth factor-1 was significantly lower in nonsurviving as compared with surviving patients (48.5 +/- 24.4 vs. 70.8 +/- 39.9; p = 0.044), as well as cholesterol (80.3 +/- 35.7 vs. 147.4 +/- 53.1; p < 0.001) and albumin (1.9 +/- 0.4 vs. 2.4 +/- 0.7; p = 0.018). Groups were similar regarding transferrin, lymphocyte, triceps skinfold thickness, arm muscle area, and subjective global nutritional assessment. A binary logistic regression model based on insulin-like growth factor-1 < or = median (50.6 ng/mL), presence of sepsis, oliguria, and cholesterol < or = median (96 mg/dL) identified insulin-like growth factor-1 (odds ratio = 7.73; 95% confidence interval 1.19-49.87; p = 0.032), sepsis (odds ratio = 7.28; 95% confidence interval 1.29-40.89; p = 0.024), oliguria (odds ratio = 8.7; 95% confidence interval 1.10-68.77; p = 0.040) and cholesterol (odds ratio = 10.94; 95% confidence interval 1.89-63.29; p = 0.008) as independent covariate for death.
    Conclusions: Decreased levels of insulin-like growth factor-1 and cholesterol were clearly related to higher mortality. The close correlation of insulin-like growth factor-1 with nutritional status, its serum stability, and short-half life makes it a suitable candidate for an early and sensitive marker for intensive care unit acute kidney injury mortality.
