Integrated Multi-Biomarker Responses of Juvenile Zebra Seabream (Diplodus cervinus) to Warming and Acidification Conditions

The impacts of climate change-related stressors are becoming more noticeable in the ocean, particularly in coastal marine ecosystems. Yet limited information still exists on the physiological state and ecological resilience of marine fish species, especially during their early life stages (i.e., larvae and juveniles). The present study investigated the effects of chronic exposure to seawater warming (OW; ΔT = +4 °C) and acidification (OA; ΔpH = −0.3 pH units, equivalent to pCO2~1000 µatm), acting alone or combined (OWA), on juvenile zebra seabream (Diplodus cervinus) physiological resilience, considering distinct levels of biological organization (i.e., biochemical, cell, organ and individual levels). After 60 days of exposure, both stressors, in isolation or combination, significantly decreased specific growth rate (−11% in OW, −42% in OA and −49% in OWA) and leukocyte counts (from −29% in OA and OWA up to −37% in OW) in relation to the control treatment. In addition, a decreased Fulton’s condition index (K) was observed under warming and acidification in combination (−35% in OWA). At the cell level, OW, OA and OWA triggered different biomarker responses in D. cervinus (i.e., up-regulation, down-regulation, or absence of significant effect). In general, the results are suggestive of an antagonistic effect when warming and acidification are combined. OWA yielded the highest integrated biomarker response (IBR) index value in the whole organism, muscle, brain and gills of D. cervinus juveniles, therefore suggesting that the effects of these stressors are more severe when they act together. The distinct patterns observed in each stress scenario highlight the importance of carrying out further studies adjusted to the specificities of different regions, i.e., accounting not only for the type and degree of severity of environmental stressors already felt and/or projected for that specific area, but also the physiological plasticity of species that inhabit a particular ecosystem. The gathered knowledge will allow one to determine the vulnerability of particular marine species and geographic areas and, most importantly, to draw up effective and tailor-made conservation strategies to overcome climate change impacts.

Sustitución parcial de harina de trigo por harina de camote naranja (Ipomoea batatas) y su efecto en las propiedades bromatológicas y sensoriales de galletas dulces

The objective of the research was to evaluate the partial substitution of wheat flour with orange sweet potato flour (Ospf) in the preparation of sweet cookies. A completely randomized design with a factorial arrangement was applied. The factor under study corresponded to the concentrations of Ospf (10, 20, and 30 %) plus a control treatment. Bromatological parameters, texture, and sensory profile were evaluated. The LSD Fisher and Kruskal Wallis multiple comparison tests were used at 5 % significance. The proximate composition of the orange sweet potato flour presented in protein 3.99 ± 0.02 %; moisture 8.65 ± 0.00 %; dry matter 91.34 ± 0.06 %; ash 4.24 ± 0.00 %; pH 6.41 ± 0.01; acidity 0.69 ± 0.01 % and particle size 354 ± 0.02 µm. In the processed products (sweet cookies), except for the energy parameter, the other bromatological variables presented statistical significance (p<0.05). Regarding the texture profile, the parameters hardness, brittleness, and adhesive force were significantly different (p<0.05) between the treatments, while, for adhesiveness, cohesiveness, gumminess, elasticity, and chewiness a p>0.05 (no significant) was obtained. At the sensory level, the untrained tasters expressed the acceptability of ‘‘I neither like it nor dislike it’’ in the attributes, flavor, smell, texture, and consistency; however, in color, the formulations with the factor under study presented greater acceptance. The sweet cookies met the requirements established in the INEN 2085 reference standard for cookies. Keywords: sweet potato, cookies, Ipomoea batatas, texture profile, tubers

The curvilinear responses of biomass accumulation and root morphology to a soil salt-nitrogen environment reflect the phytodesalination capability of the euhalophyte Suaeda salsa L.

Under the sufficient nitrogen supply, it is of great significance to investigate the law of biomass allocation, root morphological traits, and the salt absorption capacity of euhalophytes to evaluate their biological desalination in saline soil. Although the curvilinear responses of biomass accumulation and root morphology in response to soil salinity have been recognized, these perceptions are still confined to the descriptions of inter-treatment population changes and lack details on biomass allocation in organs at an individual level. In this study, Suaeda salsa was grown in root boxes across a range of soil salt levels. The study showed that their growth and development were significantly affected by soil soluble salts. The law of biomass allocation was described as follows: increased soil soluble salts significantly increased the leaf mass ratio and decreased the stem mass ratio, and slightly increased the root mass ratio among treatments. For individuals at each treatment, leaf mass ratio > stem mass ratio > root mass ratio, except in the control treatment at the flower bud and fruit stages. Biomass responses of the control treatment indicated that salt was not rigorously required for Suaeda salsa in the presence of an adequate nitrogen supply, as verified by the correlation between biomass, nitrogen, and soil soluble salt. Salt could significantly inhibit the growth of Suaeda salsa (P<0.01), whereas nitrogen could significantly promote its growth (P<0.01). Root morphology in response to soil soluble salts showed that salt acquisition by the root was highest at a salt level of 0.70%, which corresponds to light saline soil. Consequently, we conclude that phytodesalination by Suaeda salsa was optimal in the light saline soil, followed by moderate saline soil.

Poly I: C Alleviated Duck Intestinal Injury Infected with Duck Viral Enteritis by Inhibiting Apoptosis.

Duck enteritis virus (DEV) may lead to vascular injury, gastrointestinal mucosal erosion, lymphoid organ injury, and Polyinosinic-polycytidylic acid (Poly I:C) has an antiviral effectby inducing low levels of interferon. The purpose of this study was to explore the pathogenesis of DEV-induced intestinal injury in ducks and to verify the therapeutic effects of different concentrations of Poly I:C. In this study, duck enteritis model was established by infecting healthy Pekin ducks with DEV. Duck intestinal tissues were extracted from normal control group, model group, and treatment group with different doses of Poly I:C. In vivo, HE and TUNEL staining were used to observe the morphological changes and apoptosis. In vitro, the proliferation and apoptosis of duck intestinal epithelial cells were evaluated by MTT assay, TUNEL staining, and flow cytometry. The results showed that Poly I:C protected ducks from DEV toxicity by improving intestinal morphology and inhibiting apoptosis. In addition, the antiviral effect of Poly I:C on DEV was found in a dose-dependent manner, with a more relatively obvious effect at a high dose of Poly I:C. All in all, these results demonstrated that Poly I:C played a vital role in the apoptosis induced by DEV in ducks and modest dose of Poly I:C treatment worked well and may provide important reference for the development of new antiviral drugs in the future.

A Meta-Analysis of Interpersonal and Psychodynamic Psychotherapies for Posttraumatic Stress Disorder.

Established trauma-focused cognitive-behavioral therapies for posttraumatic stress disorder (PTSD) have remission rates of approximately 30%-40%. Alternatively, interpersonal psychotherapy (IPT) and psychodynamic psychotherapy (PDT) focus on disrupted attachment, mentalization, and social connection in PTSD and may help some patients. The authors conducted a meta-analysis on these interpersonal and affect-oriented approaches to treating PTSD. Building on a prior meta-analysis, the authors searched for randomized controlled trials (RCTs) comparing IPT or PDT with other established PTSD treatments or control conditions for adults diagnosed as having PTSD. Random-effects meta-analyses were conducted to assess outcome effect sizes and dropout rates. RCTs were rated via the Randomized Controlled Trial Psychotherapy Quality Rating Scale. Ten RCTs (eight of IPT) comparing IPT or PDT with control (k=7) or active treatment (k=4) conditions were identified, nine of which were of adequate quality. IPT (k=5) and PDT (k=2), when analyzed together, were superior to control conditions overall (g=-1.14, p=0.011 [as was IPT alone: g=-0.88, p=0.034]) and to waitlist (g=-1.49) and treatment-as-usual (g=-0.70) groups. Effect sizes, however, may have been inflated by outliers or publication bias. IPT (k=3) and PDT (k=1), when analyzed together, were equally efficacious compared with other active PTSD treatments (primarily exposure-based psychotherapies), as was IPT alone, and had lower dropout rates (relative risk=0.63, p=0.049 for IPT and PDT analyzed together; relative risk=0.61, p=0.098 for IPT alone). Affect-focused therapies hold promise in the treatment of PTSD. IPT has demonstrated efficacy in multiple trials, whereas the evidence base for PDT is sparse.

Enhancing Rooting in Morus alba Cuttings: Effects of Indolebutyric Acid and a Commercial Rooting Agent across Branch Positions

Sericulture is the cultivation of silkworms to produce silk using white mulberry leaves (Morus alba L.); thus, the sector's quality production of mulberry seedlings on a large scale is economically important. The production of seedlings through cuttings is the most effective and fastest reproduction method. Still, it can also be enhanced using synthetic rooting agents, increasing the productive potential of white mulberry crops. The current work aims to evaluate the response of cuttings taken from different parts of the branch of M. alba var. Miura (Apical 1, Apical 2, Medial, Basal 1, and Basal 2) and treated with indolebutyric acid (IBA; 500, 1,000, and 1,500 mg L-1) and commercial rooting agent Forth® (10 % v/v), in addition to a control treatment. After treating the branches, they were placed in polyethylene containers filled with substrate and kept in a greenhouse for 70 days. The application of hormones on cuttings of M. alba favored several morpho-agronomic parameters evaluated for the propagules obtained from different positions on the branch. In conclusion, applying 500 or 1,000 mg L-1 of IBA is recommended for the various positions, with Basal 1 and Basal 2 showing higher values ​​in the evaluated parameters than the other positions. The results can help silk breeders optimize white mulberry crop production.

Efficacy and safety of ramucirumab for gastric or gastro-esophageal junction adenocarcinoma: a systematic review and meta-analysis.

Based on the comparison of ramucirumab monoclonal antibody with control treatments in randomized controlled trials, this study aims to elucidate the role of ramucirumab monoclonal antibody in cancer therapy and its potential side effects, providing scientific evidence for clinical treatment. PubMed, Embase, Cochrane, and Web of Science were searched systematically to obtain the trials on ramucirumab in the treatment of gastric or gastroesophageal junction (GEJ) adenocarcinoma up to April 13, 2023. We included randomized controlled trials (RCTs) evaluating the efficacy and safety of ramucirumab as monotherapy and in combination with other chemotherapy agents as interventions for treating gastric or gastroesophageal junction (GEJ) adenocarcinoma. After screening 2200 studies, we finally included 8 eligible studies (involving a total of 3,283 participants). Meta-analysis results showed that compared to the control group, ramucirumab monotherapy significantly improved overall survival (OS) (hazard ratio [HR] = 0.77, 95% confidence interval [CI] [0.67, 0.89]) and progression-free survival (PFS) (HR = 0.48, 95% CI [0.40, 0.58]). Similar results were obtained for ramucirumab combined with paclitaxel. In the treatment combining ramucirumab with paclitaxel, compared to monotherapy, three severe adverse reactions (grade ≥ 3) were observed with significantly increased risks (OR > 2). These include proteinuria (OR = 5.37, 95% CI [1.22, 23.54]), hypertension (OR = 4.02, 95% CI [2.63, 6.14]), and gastrointestinal perforation (OR = 4.64, 95% CI [1.00, 21.60]). Subgroup analysis further indicated that ramucirumab is effective in both non-East Asian and East Asian populations, with East Asian patients more prone to developing proteinuria, while having a lower incidence of hypertension. Additionally, ramucirumab demonstrated comparable efficacy between first-line and second-line treatments, with a higher incidence of proteinuria observed in second-line therapy. Ramucirumab significantly improves the prognosis of patients with gastric or gastroesophageal junction adenocarcinoma. When used in combination with paclitaxel, close monitoring of adverse reactions such as proteinuria (especially in East Asian populations), hypertension (especially in non-East Asian populations), and gastrointestinal perforation is essential.

Effectiveness of Injection Strategies on Patients With Patellar Tendonitis (Jumpers' Knee): A Network Meta-analysis of Randomized Controlled Trials.

Patellar tendonitis (PT) is a common degenerative disease of the patellar tendon that seriously affects the sports careers of elite athletes and activities of daily living of sports enthusiasts. Injection therapy is a prevalent invasive treatment for PT. This work comprehensively analyzes various injection treatments for PT that consider agent type and characteristics, frequency, and assessment timepoints by meta-analysis. PubMed, Embase, and the Cochrane Library were sources of data. Randomized controlled trials (RCTs) analyzing the effect of various injection strategies on the treatment of patients with PT were considered. Systematic review and meta-analysis. Level 2. First author, year of publication, research location, registration information, patient type, sample size, age, sex, intervention, control treatment, and follow-up period in each study were extracted. Nineteen RCTs were included in the analysis. In the network meta-analysis of Victorian Institute of Sports Assessment-Patellar (VISA-P) outcomes, polidocanol (standardized mean difference (SMD), 6.52; 95% CI 4.75, 8.30; P < 0.01), tenocyte-like cells (SMD, 4.08; 95% CI 2.92, 5.25; P < 0.01), and leukocyte-poor platelet-rich plasma (LP-PRP) plus high-volume image-guided injection (HVIGI) (SMD, 1.56; 95% CI 0.62, 2.50; P < 0.01) were significantly superior to noninjection conservative treatment, mainly at the 6-month follow-up timepoint. For visual analog scale results, multiple dry needling (DN) (SMD, -1.78; 95% CI -2.56, -1.00; P < 0.01), LP-PRP (SMD, -0.71; 95% CI -1.31, -0.12; P = 0.02), and LP-PRP plus HVIGI (SMD, -1.31; 95% CI -2.22, -0.39; P < 0.01) were significantly superior to blank, which was also mainly at the 6-month timepoint. Injection-related treatments: polidocanol, tenocyte-like cells, LP-PRP, and multiple DN showed potential short (1-3 months) or medium (6 months)-term treatment benefits. There is still no evidence for injection interventions with long-term therapeutic benefit.

Effect of Different Levels of Farmyard Manure (FYM) Integrated with Organic Modules on Yield, Quality and Pest Incidence of Okra (Abelmoschus esculentus L. Moench)

The study was conducted during late Kharif season during 2021-22 and 2022-23 at administrative office (PGIHS), Sri Konda Laxman Telangana State Horticultural University, Mulugu, Telangana, India. The experiment was laid out in contrast factorial randomized block design (CFRBD) with two factors i.e., factor-1 consists of three levels of FYM and factor-2 consists of three organic modules and separate control (100% RDF) plot was grown and replicated thrice. The pooled results indicated that, control treatment (100 % RDF-100:50:50 kg NPK/ha) reported highest number of fruits per plant (19.05), highest fruit weight (14.72 g), maximum fruit yield per plant (0.28 kg), maximum fruit yield per hectare (9.52 t/ha) over the other treatments. L1M1 (FYM equivalent to 100 % RDN + organic module-1) registered minimum crude fibre content (7.10%), and maximum chlorophyll content in fresh fruit (1.19 mg/100g). While, minimum mean percent of fruit infestation (6.28%) was reported with control (100% RDF-100:50:50kg NPK/ha + emamectin benzoate 5%SG @ 70 g/200 lit) and lowest mean population of jassid per leaf (1.08/leaf), was recorded with control (100 % RDF-100:50:50 kg NPK/ha + imidacloprid 17.8 SL @ 100 ml/acre).

Examining the Effect of Missing Data and Unmeasured Confounding on External Comparator Studies: Case Studies and Simulations.

Missing data and unmeasured confounding are key challenges for external comparator studies. This work evaluates bias and other performance characteristics depending on missingness and unmeasured confounding by means of two case studies and simulations. Two case studies were constructed by taking the treatment arms from two randomised controlled trials and an external real-world data source that exhibited substantial missingness. The indications of the randomised controlled trials were multiple myeloma and metastatic hormone-sensitive prostate cancer. Overall survival was taken as the main endpoint. The effects of missing data and unmeasured confounding were assessed for the case studies by reporting estimated external comparator versus randomised controlled trial treatment effects. Based on the two case studies, simulations were performed broadening the settings by varying the underlying hazard ratio, the sample size, the sample size ratio between the experimental arm and the external comparator, the number of missing covariates and the percentage of missingness. Thereby, bias and other performance metrics could be quantified dependent on these factors. For the multiple myeloma external comparator study, results were in line with the randomised controlled trial, despite missingness and potential unmeasured confounding, while for the metastatic hormone-sensitive prostate cancer case study missing data led to a low sample size, leading overall to inconclusive results. Furthermore, for the metastatic hormone-sensitive prostate cancer study, missing data in important eligibility criteria led to further limitations. Simulations were successfully applied to gain a quantitative understanding of the effects of missing data and unmeasured confounding. This exploratory study confirmed external comparator strengths and limitations by quantifying the impact of missing data and unmeasured confounding using case studies and simulations. In particular, missing data in key eligibility criteria were seen to limit the ability to derive the external comparator target analysis population accurately, while simulations demonstrated the magnitude of bias to expect for various settings.

An evaluation of the growth, development, reproductive characteristics and pest control potential of three Trichogramma species on Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae).

Tuta absoluta is an invasive alien species that has caused major losses in the Chinese tomato industry. Investigating the growth, development, reproduction and pest control effects of three native species of Trichogramma species on the eggs of T. absoluta could provide an ecological tool for preventing and controlling T. absoluta in China. In this study, we constructed age-stage two-sex life tables for three common species of Trichogramma and determined their relative abilities to control T. absoluta in greenhouse insect cages, thus allowing us to identify the species with the most effective ability to prey on T. absoluta eggs. Analysis showed that the net reproductive rate (R0), gross reproduction rate (GRR) and intrinsic rate of increase (r) of Trichogramma ostriniae were the highest of the three species at 22.85, 32.58 and 1.31, respectively. In the presence of 10 eggs and under ideal conditions, T. ostriniae, Trichogramma chilonis, and Trichogramma dendrolimi produced 9451.04, 5199.56, and 1902.95 offspring, respectively. Following the release of T. ostriniae, tomato leaves incurred a damage index of 1 after the first week, while the number of T. absoluta reduced to 24.60 individuals by week 10 (8.75% of the control treatment). Of the three species of Trichogramma tested in this study, T. ostriniae exhibited the best growth, development, reproductive capacity and predatory ability against T. absoluta, and has broad application prospects. © 2024 Society of Chemical Industry.

Exploiting Soybean and Flaxseed Meal Byproducts as Safe Weed Management Approaches in Onion Field

AbstractThe intensive and repeated use of chemical herbicides has led to the emergence of herbicide-resistant weeds, which, in addition to their environmental impacts, also pose significant threats to human and animal health. This study aimed to explore the potential of oilseed industrial wastes, specifically soybean and flaxseed meals, as safe and environmentally friendly bioherbicides for controlling weeds associated with onion crops. Two field experiments were conducted along two successive winter of 2020/21 and 2021/22. Treatments involved foliar spray of soybean and flaxseed meals in three different concentrations (15, 30 and 45%), mulching of seed meals, oxyfluorfen herbicide, two hand hoeing and untreated weedy check. The findings demonstrated that all weed control treatments significantly reduced weed density, biomass and nutrient uptake. Two hand hoeing, oxyfluorfen herbicide and the mulching of soybean and flaxseed meals alternated in the top rank for weed control, showing minimal significant differences among them. Following these effective treatments, soybean meal extracts at 45 and 30% exhibited notable weed control compared to the weedy check. The greatest enhancement in onion growth, yield characteristics and bulb quality was observed with the application of hand hoeing, soybean and flaxseed meal mulching treatments, with no significant differences between them. High-Performance Liquid Chromatography (HPLC) fractionation of both meals identified various phenolic acids at different concentrations. Practically, these safe efficient treatments proved progress on chemical herbicide. Hence, onion farmers are advised to apply soybean and flaxseed meals mulching safe treatments as alternative to harmful chemical herbicides under all experimental conditions.

Effectiveness of Low-Level Laser Therapy in reducing postoperative pain after dental implant surgery: A randomized clinical trial

BackgroundA clinical trial was conducted to measure the effectiveness of a combined wavelength of 660 nm and 808 nm Low-Level Laser Therapy (LLLT) in reducing postoperative pain in partially and totally edentulous patients who underwent dental implant surgery. Materials and MethodsThe study included 20 blinded individuals divided in a randomized split-mouth fashion; the experimental group in one hemiarch and the control group in the other hemiarch. The experimental group received a total of 22.5 Joules (J) of LLLT divided into 5 points per implant immediately after surgery. The control group received a placebo treatment. At 24 h, 72 h, and 7 days, a blinded surveyor administered a pain questionnaire using a Numerical Rating Scale (NRS) combined with a Verbal Rating Scale (VRS) to assess pain onset after surgery, duration of the first pain episode, and pain evolution. Group data were analyzed with an ANOVA test for repeated measures and a paired t-test at defined time intervals. ResultsThe experimental group showed a significant decrease in postoperative pain at 24 h and at 72 h for fully edentulous patients. There was a non-significant difference in the duration of the first pain episode. The mean pain levels decreased over time for both the experimental and control treatments, but only statistically significantly for the experimental group in the 24–72 h and 24 h to 7 days intervals. The same was true for the control group when comparing 24 and 72 h and between 24 h and 1 week. The time range between 72 h and 1 week showed no statistically significant differences. ConclusionWithin the limitations of this study, a single dose of 22.5 J LLLT per implant helps to decrease postoperative pain in dental implant surgery at 24 h for partially edentulous patients and at 24 and 72 h for fully edentulous patients.

Meta-Analysis of Dietary Supplementation with Seaweed in Dairy Cows: Milk Yield and Composition, Nutrient Digestibility, Rumen Fermentation, and Enteric Methane Emissions

This study used a meta-analytic approach to evaluate the effects of dietary supplementation with seaweed on milk yield, milk composition, nutrient digestibility, ruminal fermentation, and enteric methane (CH4) emissions of dairy cows. Data used in statistical analyses were obtained from 23 peer-reviewed scientific articles. Effect size was assessed using weighted mean differences (WMD) between seaweed-supplemented and control treatments. Dietary supplementation with seaweed decreased (p &lt; 0.05) dry matter intake, milk protein content, milk urea nitrogen, and somatic cell count. In contrast, milk fat content, milk lactose content, and milk iodine increased (p &lt; 0.05) in response to dietary supplementation with seaweed. Dietary supplementation with seaweed did not affect (p &gt; 0.05) nutrient digestibility, total volatile fatty acids, acetate, and propionate. Dietary supplementation with seaweeds increased (p &lt; 0.05) ruminal pH and ruminal concentration of butyrate and valerate. In contrast, lower (p &lt; 0.05) ruminal ammonia nitrogen concentration, acetate/propionate ratio, daily CH4 emission, CH4 yield, and CH4 intensity were observed in response to dietary supplementation with seaweeds. In conclusion, dietary supplementation with seaweed modifies milk composition, improves ruminal fermentation, and decreases enteric methane emissions without negatively affecting milk yield or feed efficiency.

Chemical Desiccation in the Preharvest of Cowpea: A Study of How the Time of Application Interferes in the Enzymatic and Physiological Aspects of Seedlings from Desiccated Plants.

Chemical desiccation in the preharvest of grains and seeds is commonly used in production fields. Using herbicides for this purpose is a viable alternative to reduce beans' exposure to adverse crop conditions. Our objectives were to evaluate (1) the efficacy of herbicides for accelerated defoliation of cowpea, (2) the impact of herbicide application on antioxidant enzyme activity and protein and amino acid contents in seeds, and (3) the effects of different herbicide application schedules on the physiological aspects of seeds. In the first experiment, in addition to the control treatment (without herbicides), seven herbicides and two mixtures were applied at night: diquat, flumioxazin, diquat + flumioxazin, glufosinate ammonium, saflufenacil, carfentrazone, diquat + carfentrazone, atrazine, and glyphosate. Diquat and its mixtures showed greater efficacy in anticipating the harvest. Flumioxazin and diquat alone reduced amino acid content by 61.72 and 51.44%, respectively. The same trend was observed for total soluble proteins. The activity of antioxidant enzymes (CAT, POD, PPO) increased, indicating oxidative stress caused by diquat and flumioxazin. In the second experiment, we tested three application times (6 a.m., 12 p.m., 6 p.m.) with diquat, diquat + flumioxazin, and diquat + carfentrazone. The lowest damage to chlorophyll a was at 6 a.m.; other times reduced photosynthetic pigments and increased carotenoid content. Total soluble sugars decreased by 27.74% with nocturnal application of diquat + flumioxazin. Our data indicate that herbicide use for desiccation affects seed quality. These findings highlight the need for selecting appropriate herbicides and application times. Future research should explore long-term impacts on crop yield and quality.

Evaluation of Resistance Induction Promoted by Bioactive Compounds of Pseudomonas aeruginosa LV Strain against Asian Soybean Rust.

Pseudomonas are known as higher producers of secondary metabolites with antimicrobial properties and plant growth promoters, including resistance induction. These mechanisms should be an alternative to pesticide use in crop production. Phakopsora pachyrhizi causes Asian soybean rust, representing a high loss of yield around the world. The objective of this paper was to evaluate the application of secondary metabolites produced by Pseudomonas aeruginosa LV strain from the semi-purified fraction F4A in soybean plants to induce plant resistance against P. pachyrhizi in field conditions. The experimental design was performed in randomized blocks with three replicates using two F4A doses (1 and 10 μg mL-1) combined or not with fungicides (Unizeb Gold® or Sphere Max®). The control treatment, with Uni + Sph, saponins, flavonoids, and sphingolipids, showed higher intensities in the plants. In contrast, plants treated with the F4A fraction mainly exhibited fatty acid derivatives and some non-identified compounds with nitrogen. Plants treated with Sphere Max®, with or without F4A10, showed higher intensities of glycosylated flavonoids, such as kaempferol, luteolin, narigenin, and apigenin. Plants treated with F4A showed higher intensities of genistein and fatty acid derivatives. These increases in flavonoid compound biosynthesis and antioxidant properties probably contribute to the protection against reactive oxygen species (ROS).

Persistence of advanced systemic pharmacological treatment of moderate-to-severe psoriasis among bio-naïve patients-A retrospective register-based cohort study in Finland and Sweden.

Plaque psoriasis (PsO) requires long-term treatment for symptom control and remission; thus, a long-term pharmacological intervention is necessary. Treatment persistence reflects long-term therapeutic effectiveness and tolerance. This study investigates drug persistence and compares treatment discontinuation rates across biologic agents and apremilast used by PsO patients in Finland and Sweden. This retrospective register-based cohort study included bio-naïve patients (≥18 years) with moderate-to-severe PsO, who initiated treatment with abatacept, adalimumab, brodalumab, certolizumab pegol, etanercept, golimumab, guselkumab, ixekizumab, risankizumab, secukinumab, tildrakizumab, ustekinumab or apremilast during 2008-2020 in Finland or Sweden. The main analysis evaluated persistence (based on duration of continuous treatment) and compared rates of treatment discontinuation using guselkumab as reference drug, during 2018-2020 in Finland. Treatment discontinuation was assessed by survival analysis of the time to first drug discontinuation, including switching to other study drugs. Due to limited sample size (n < 20), certain biologics (abatacept, brodalumab, certolizumab pegol, etanercept, golimumab, risankizumab and tildrakizumab) were excluded from the persistence analysis. In Finland, 709 patients fulfilled the inclusion criteria during 2018-2020 for the main analysis. The highest persistence was observed for guselkumab and ustekinumab with 90 and 85% of treated patients, respectively, continuing treatment for ≥1 year. Comparable results were observed in the expanded cohort analysis (index starting in 2008; 2745 bio-naïve patients in Finland and 10,970 in Sweden). Furthermore, patients treated with guselkumab in Finland showed lower treatment discontinuation rates compared to other study drugs. Guselkumab and ustekinumab demonstrated high persistence as measured by continued treatment for at least 1 year. Furthermore, these treatments demonstrated lower rates of discontinuation compared to other study drugs included in the analysis. Understanding the balance between efficacy and feasibility in treatment decisions is crucial, as feasibility may impact persistency outcomes and potentially increase persistency rates.

Repurposing of the analgesic Neurotropin for MASLD/MASH treatment.

The prevalence of metabolic dysfunction-associated steatotic liver disease (MASLD) has increased in recent decades. Approximately 25% of patients with MASLD progress to metabolic dysfunction-associated steatohepatitis, which is characterized by hepatic steatosis plus hepatocyte damage, inflammation, and fibrosis. We previously reported that Neurotropin (NTP), a drug used for relieving pain in Japan and China, inhibits lipid accumulation in hepatocytes by preventing mitochondrial dysfunction. We hypothesized that inhibiting hepatic steatosis and inflammation by NTP can be an effective strategy for treating MASLD and tested this hypothesis in a MASLD mouse model. Six-week-old C57BL/6NJ male mice were fed a normal diet and normal drinking water or a high-fat diet with high fructose/glucose water for 12 weeks. During the last 6 weeks, the mice were also given high-dose NTP, low-dose NTP, or control treatment. Histologic, biochemical, and functional tests were conducted. MitoPlex, a new proteomic platform, was used to measure mitochondrial proteins, as mitochondrial dysfunction was previously reported to be associated with MASLD progression. NTP inhibited the development of hepatic steatosis, injury, inflammation, and fibrosis induced by feeding a high-fat diet plus high fructose/glucose in drinking water. NTP also inhibited HSC activation. MitoPlex analysis revealed that NTP upregulated the expression of mitochondrial proteins related to oxidative phosphorylation, the tricarboxylic acid cycle, mitochondrial dynamics, and fatty acid transport. Our results indicate that NTP prevents the development of hepatic steatosis, injury, and inflammation by preserving mitochondrial function in the liver and inhibits liver fibrosis by suppressing HSC activation. Thus, repurposing NTP may be a beneficial option for treating MASLD/metabolic dysfunction-associated steatohepatitis.

Yellow mealworm frass: A promising organic fertilizer for common sowthistle (Sonchus oleraceus L.) and bristly oxtongue (Helminthotheca echioides (L.) Holub) cultivation

Common sowthistle (Sonchus oleraceus L.) and bristly oxtongue [Helminthotheca echioides (L.) Holub] are winter broad-leaved weeds that have gained interest for cultivation as leafy vegetables. The aim of this study was to examine the effects of frass from the yellow mealworm (Tenebrio molitor L.) on nutrient content in soil, growth parameters, and nutrient content in above-ground plant tissues of common sowthistle and bristly oxtongue. Thus, two pot experiments were carried out with 5 treatments [control, calcium ammonium nitrate (CAN) applied at a dose of 100 kg N ha−1, and insect frass applied at a rate of 3500 kg ha−1 (0.5 % w/w) 7000 kg ha−1 (1 % w/w), and 14,000 kg ha−1 (2 % w/w)]. Our results showed that the lowest values of growth parameters for both plant species were recorded in the control treatment. At the final rosette growth stage [e.g., 152 days after sowing (DAS)], the CAN treatment exhibited the highest values of rosette diameter and above-ground dry weight, followed by the highest rate of insect frass. Similarly, at 152 DAS the SPAD index values in the CAN treatment were 28.4–41.5 % higher compared to the control treatment in both species. Regarding root dry weight, the highest values were found in the CAN and insect frass 2 % treatments. In addition, the application of insect frass significantly enhanced soil fertility, with the highest levels of P and K recorded in the insect frass 2 % treatment. In contrast, the CAN treatment resulted in the highest NO3–N content in the soil (15.83 and 19.26 mg kg−1 in common sowthistle and bristly oxtongue, respectively). Moreover, both P and K content in the above-ground plant tissues had the highest values in the insect frass 2 % treatment, while the content of Mg, Mn, and Cu in plant tissues was not affected by the fertilization sources. Therefore, our findings indicate that insect frass can be an additional option in crop fertilization programs as it can improve both the soil fertility and growth of crops compared to conventional inorganic fertilizer sources. However, the effects of insect frass in mixtures with inorganic fertilizers needs to be taken into consideration in future studies.

Enhancing Spinach (Amaranthus tricolor L.) Growth Using Maggot Fermentation-Derived Liquid Organic Fertilizer and AB Mix in Drip Fertigation Systems

Spinach (Amaranthus tricolor L.) is a highly nutritious leafy vegetable widely cultivated for its rich content of vitamins and minerals. To enhance spinach production sustainably, this study investigates the use of liquid organic fertilizer derived from maggot fermentation combined with AB mix nutrients, applied through a drip fertigation system. The study was conducted using three different concentrations: 2.5 ml/L, 5 ml/L, and 7.5 ml/L, with the goal of identifying optimal conditions for maximizing spinach growth. The research utilized a two-factorial, Completely Randomized Design (CRD) with five replications to evaluate the effects of these nutrient combinations on key growth parameters, including plant height, leaf number, leaf area and weight of plants. Results indicated that a concentration of 7.5 ml/L provided the most favorable growth outcomes, with a 46.5 cm increase in plant height and a biomass accumulation of 61.8 grams, representing significant improvements over control treatments. The macro-nutrient content of the maggot-derived POC met national agricultural standards, except for pH, which improved to 7.10 when combined with AB mix. These findings suggest that integrating maggot POC with AB mix offers a cost-effective and environmentally friendly alternative to conventional fertilizers, promoting sustainable agricultural practices. This study contributes to developing efficient cultivation methods for spinach, addressing increasing market demands, and reducing reliance on chemical fertilizers.
