7%) patients who had never had an ophthalmologic examination, 30 (78.9%) patients with severe NPDR or PDR had had an ophthalmologic visit within 1year. The frequency of ophthalmic visits was correlated negatively with age, diabetes duration, HbA1c, and severity of retinopathy.

Remote interpretation of DR using UWF retinal imaging was useful for retinopathy screening. During the COVID-19 pandemic, a remote screening system that can ensure compulsory social distancing and reduce the number of ophthalmic visits can be a safe system for patients and clinicians.

We had previously reported an increase in trimethylamine N-oxide (TMAO) levels in patients with both compensated and decompensated heart failure (HF) and alteration in gut microbiota composition using 16S rRNA gene amplicon analysis. Although a metagenome-wide analysis showed that choline-TMA lyase levels increased in HF patients, which TMA generation pathway from choline, carnitine, or betaine contributes to the increase in TMAO levels in HF needs to be elucidated.

We conducted a metagenome-wide shotgun sequencing analysis of gut microbiota and measured the TMAO levels in plasma of 22 HF patients during the compensated phase and 11 age-, sex-, and comorbidity-matched control subjects, whose gut microbiota compositions were reported in a previous 16S rRNA-based analysis.

The abundance of cntA/B was positively correlated with TMAO, especially in HF patients, whereas that of cutC/D or betaine reductase was not correlated either in controls or HF patients. The abundance of cntA/B was mainly derived from the genera Escherichia and Klebsiella either in controls or HF patients.

TMAO levels in plasma depend on the abundance of cntA/B in HF. Although it is difficult to exclude the involvement of confounding factors, microbial dysbiosis connecting the abundance of cntA/B in the gut and the increase of TMAO in plasma can be a therapeutic target for HF.

Considering that behavior is directly related to reproduction, individual fitness, and survival, it is important to evaluate the impact of antibiotics on the behavioral repertoire in fish. Zebrafish (Danio rerio) presents a well-described behavioral repertoire to reliably demonstrate complex responses to chemical compound exposure. This work aims to identify the role of OTC in comprehensive behavioral parameters and whole-body cortisol levels in adult zebrafish. Here we report that OTC exposure (10, 20, and 100 mg/L) induces an anxiogenic-like phenotype in the novel tank test. OTC exposure also changes the behavior of social interaction with a shoal of unknown zebrafish - characterized as a stimulus group. Zebrafish exposed to OTC (10 mg/L) remains a longer period in the stimulus zone when compared to the control group. Clonazepam (0.006 mg/L) was able to reverse anxiogenic-like behavior and the changes in social behavior induced by OTC. We also demonstrated that cortisol levels were significantly decreased after exposure to OTC (10, 20, and 100 mg/L), which were not reversed by clonazepam.

Considering the importance of endothelin (ET) and thromboxane A2 (TXA2) signaling in PE pathophysiology, we tested the hypothesis that prenatal blockade of endothelin ETA or thromboxane TXA2 receptors favorably reprograms preeclamptic cardiovascular and renal insults. PE was induced by daily oral administration of L-NAME (50 mg/kg) to pregnant rats for 7 consecutive days starting from gestational day 14. The effects of co-exposure to atrasentan (ETA receptor blocker, 10 mg/kg/day) or terutroban (TXA2 receptor blocker, 10 mg/kg/day) on cardiovascular and renal anomalies induced by PE were assessed on gestational day 20 (GD20) and at weaning time and compared with those evoked by the sympatholytic drug α-methyldopa (α-MD, 100 mg/kg/day), a prototypic therapy for PE management. Among all drugs, terutroban was basically the most potent in ameliorating PE-evoked increments in blood pressure and decrements in creatinine clearance. Cardiorenal tissues of PE rats exhibited significant increases in ETA and TXA2 receptor expressions and these effects disappeared after treatment with atrasentan and to a lesser extent by terutroban or α-MD. Atrasentan was also the most effective in reversing the reduced ETB receptor expression in renal tissues of PE rats. Signs of histopathological damage in cardiac and renal tissues of PE rats were mostly improved by all therapies. Together, pharmacologic elimination of ETA or TXA2 receptors offers a relatively better prospect than α-MD in controlling perinatal cardiorenal irregularities sparked by PE.

Stress urinary incontinence (SUI) is prevalent among older women and can result from insufficient regeneration of the pudendal nerve (PN). Electrical stimulation (ES) of the PN upregulates brain derived neurotrophic factor (BDNF) and accelerates regeneration. Using tyrosine kinase B (TrkB) to reduce the availability of free BDNF, the aim of this study was to determine if BDNF is necessary for accelerated recovery via ES in a model of SUI.

Our SUI model consists of Female Sprague-Dawley rats, whose PNs were crushed bilaterally twice for 30s, followed by insertion of a modified Foley catheter into the vagina with balloon inflation for 4h. These rats were divided into 4 groups 1) Sham PN crush and sham vaginal distension without electrode implantation and with saline treatment (sham injury); 2) SUI with sham stimulation and saline treatment (SUI); 3) SUI and ES with saline treatment (SUI&ES); and 4) SUI and ES with TrkB treatment (SUI&ES&TrkB). Animals underwent ES or sham stimulation four times se findings suggest ES could be used as a potential regenerative therapy for women with SUI.Recently we provided a new interpretation that increased serum ALP in dogs is not adverse if no hepatotoxic finding coexists in the analysis of toxicity studies of over 200 pesticides evaluated in Japan (Yokoyama et al., 2019). We also proposed a decision tree to evaluate the adversity of the increased ALP. The present analysis was conducted to validate the reliability of this interpretation with 129 pesticides more recently evaluated. Before applying, the decision tree was revised to be consistent in all steps. The pesticides showed similar characterization of increased ALP to the previous analysis in that the increase was more frequent than in rats and that liver hypertrophy and hepatotoxicity commonly coexisted with an increase in ALP in dogs. When short- and long-term studies of 58 pesticides inducing ALP activity in dogs were applied to the revised tree, the increased ALP in 8 pesticides was judged not adverse in either study. The revision of the tree did not affect the NOAEL judgment of these pesticides; however, the revised routes contributed to the judgment more robustly. This study showed the reliability of our interpretation and applicability of the decision tree to evaluate the adversity of increased ALP in dogs.Nanofibers have a particular benefit when delivering a spectrum of therapeutic drugs for diverse biomedical applications. Nanofibers are easily fabricated from cellulose acetate, chitosan, polycaprolactone, and other polymers with regulated morphology and release profiles due to nanotechnology's recent advancement. This review will provide the latest approaches to the fabrication of electrospun nanofibers containing herbal extracts, antimicrobial peptides, and antibiotics for wound-healing potential. Besides, synthesis and evaluation of nanofibrous mats, including conducting polymer and evaluate their possibility for wound healing. In addition, nanofibers are loaded with some drugs for skin cancer treatment and contain growth factors for tissue regeneration. Also, the current two-dimensional nanofibers limitations and the various techniques for convert two-dimensional to three-dimension nanofibers to avoid these drawbacks. Moreover, the future direction in improving the three-dimensional structure and functionality has been including.The carriers for hydrophobic bioactives have been extensively studied, while those for hydrophilic bioactives are still challenging. The partition of bioactives in the particles depends greatly on their solubility, interaction with carrier materials, as well as structure of carriers. In this study, chitosan-coated hollow zein particles using calcium phosphate as a sacrificing template (CS-HZ) were fabricated to co-encapsulate folic acid (FA) and caffeic acid (CA). Partition, photostability, and antioxidant capacity of bioactive compounds were also studied. The size, polydispersity index and ζ-potential of optimized CS-HZ were 176.3 nm, 0.14 and +39.3 mV, respectively, indicating their small and uniform dimension with excellent colloidal stability. FA interacted with chitosan to form complexes and then coated on the zein particles where CA was encapsulated. After co-encapsulation in CS-HZ, the photostability of both FA and CA was improved in comparison with encapsulation of single compound, with 85% of FA remaining after 240 min of UVA irradiation, and 90% of CA remaining after 80 min. Antioxidant activity of CA decreased upon encapsulation, but significantly increased after irradiation. Findings in this study shed some light on the design of carriers for co-delivery of hydrophilic compounds in acidic condition.Guar gum (plant-based polysaccharide) is a promising candidate with immense potential. It is used as emulsifier, thickener, stabilizer, and as binding agent in many industries. In the present project, it was planned to synthesize guar gum based polyurethanes by varying the amount of guar gum. Guar gum (GG) was used along with hydroxyl-terminated polybutadiene (HTPB) as soft segment, which was then reacted with isophorone diisocyanate (IPDI) to form PU pre-polymers. In last step, these -NCO terminated pre-polymers were extended with 1,4 butane diol as chain extender. The prepared polyurethane samples were then characterized by using FTIR, solid-state 1HNMR and X-ray diffraction (XRD). Thermal behavior of the samples was studied by thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). Results indicated that the incorporation of guar gum in PU backbone improved its thermal behavior and crystallinity.Effective controls on viral infections rely on the continuous development in vaccine technology. Nanoparticle (NP) antigens are highly immunogenic based on their unique physicochemical properties, making them molecular scaffolds to present soluble vaccine antigens. Here, viral targets (113-354 aas) were genetically fused to N terminal of mi3, a protein that self-assembles into nanoparticles composed of 60 subunits. With transmission electron microscopy, it was confirmed that target-mi3 fusion proteins which have insertions of up to 354 aas in N terminal form intact NPs. Moreover, viral targets are surface-displayed on NPs as indicated in dynamic light scattering. NPs exhibit perfect stability after long-term storage at room temperature. Moreover, SP-E2-mi3 NPs enhance antigen uptake and maturation in dendritic cells (DCs) via up-regulating marker molecules and immunostimulatory cytokines. Importantly, in a mouse model, SP-E2-mi3 nanovaccines against Classical swine fever virus (CSFV) remarkably improved CSFV-specific neutralizing antibodies (NAbs) and cellular immunity related cytokines (IFN-γ and IL-4) as compared to monomeric E2.
