Mucosal responses in the skin and gill filaments of Atlantic salmon (Salmo salar) infected by Neoparamoeba perurans

Gill health is crucial for maintaining respiratory and immunological functions in fish, yet it is often compromised by parasitic infections and treatments. This study investigates the effects of amoebic gill disease (AGD) and peracetic acid (PAA) treatment on mucous cell (MC) parameters in the gill filaments of Atlantic salmon (Salmo salar). Although exposure to AGD, with or without PAA treatment, did not cause changes in the mucosal parameters of the skin in Atlantic salmon, there was an increase in the mucosal parameters in the gill filaments 24 hours post-treatment and a significant increase four weeks post-treatment. These findings suggest that while AGD and PAA treatment do not affect skin mucosa, they disrupt mucosal homeostasis in the gill filaments as well as in the gill lamellae. In AGD-affected fish, hyperplasia and hypertrophy of MCs in both gill lamellae and filaments increase the diffusion distance across the water-blood barrier, leading to respiratory disturbances.

Improved textural properties of transglutaminase treated milk acid gel: Influence of citric acid

Keeping the stability of yogurt during the fermentation, storage and transportation process is necessary to reduce the syneresis. To achieve this goal, the combination of the acid treatment and transglutaminase (TG) was proposed to improve the textural properties of milk acid gels. We investigated the synergistic effect of acid treatment and TG on the water holding capacity (WHC) and physical stability of milk acid gels. As the pH of the skimmed milk decreased from 6.7 to 5.2, the casein micelles dissociated into smaller particles, exposing more site for the crosslinking of TG. The WHC and stability of the TG-treated acid gels were significantly enhanced as the particle size of casein micelles decreased. Our results suggested that the combination of the treatment of acid and TG could significantly improve the textural properties of milk acid gels by the dissociation of casein micelles induced and increase in the covalent-crosslinking. This study provided a simple and novel method to improve the stability of the milk gels, which showed enormous potential for dairy processing.

Effect of Seaweed Extract and Humic Acid Treatment on the Phenological and Yield Characteristics of Guava (Psidium guajava L.)

Aim: The main aim of this study was to evaluate the impact of seaweed and humic acid treatment at different doses on the phenological characteristics and yield of guava. Study Design: Randomized block design. Place and Duration of Study: A field experiment was conducted from December 2023 to July 2024 to assess the impact of bio-stimulants on the phenological and yield traits of guava (var. Arka Kiran) in the Poongunam village, Chengalpattu Dist, Tamil Nadu, India. Methodology: The experiment followed a Randomized Block Design with eight treatments: T₁ - Absolute control, T₂ - Water Spray, T₃ - 1% Seaweed Extract, T₄ - 1.5% Seaweed Extract, T₅ - 2% Seaweed Extract, T₆ - 1% Humic Acid, T₇ - 1.5% Humic Acid, and T₈ - 2% Humic Acid, each replicated three times. Results: Results showed that 2% Seaweed Extract (T₅) significantly improved flower retention (7.55 flowers per shoot), reduced the duration from flowering to fruit set (12.47 days), and shortened the time from fruit set to harvest (121.56 days). T₅ also led to the highest fruit set (68.65%), lowest fruit drop (48.72%), largest fruit weight (150.02 g), and greatest yield (13.35 kg/tree). Humic Acid at 2% (T₈) also improved fruit set (64.32%), fruit drop (49.54%), and yield (12.34 kg/tree), but was less effective than Seaweed Extract. Conclusion: This study demonstrates the potential of Seaweed Extract as a powerful bio-stimulant to enhance guava production, offering a sustainable alternative to traditional chemical treatments.

Effect of Post Sizes and Citric Acid Treatment on the Bond Strength of Fiber Posts Using Self-Etch Resin Cement in Calcium Silicate–Based Sealer Treated Teeth

Abstract Objectives This study evaluated the effects of different post sizes and citric acid (CA) treatment on the bond strength of fiber posts cemented with self-etch resin cement in teeth obturated with calcium silicate–based sealer. Materials and Methods Seventy mandibular premolars were collected and randomly distributed to either a control group (no sealer) or experimental groups obturated with calcium silicate–based sealer (iRoot SP). The experimental groups were classified by post sizes—1.25 mm (no. 1), 1.375 mm (no. 2), and 1.50 mm (no. 3)—and the irrigants used (distilled water [DW] or CA). Prefabricated fiber posts were fixed using NX3 self-etch resin cement. Push-out bond strength was tested in the coronal and middle sections of the roots. Statistical Analysis The data were analyzed using a one-way analysis of variance (ANOVA), followed by a post hoc Duncan test. Results In the coronal section, post size no. 1 with DW showed significantly lower bond strength compared to the other experimental groups (p < 0.05). In the middle section, the larger post sizes (nos. 2 and 3) with CA treatment resulted in a significant increase in bond strength compared to the control group (p < 0.05). Conclusions iRoot SP negatively affected bond strength in the middle section of the canal. However, using larger post sizes (nos. 2 and 3) with CA treatment improved bond strength in the middle section.

The change of phase composition and the morphology of particles of hydrothermal titanosilicate precipitates during their aging

During the study of phase formation under conditions of hydrothermal synthesis of alkaline titanosilicate systems (NH₄)₂TiO(SO₄)₂⋅H₂O или TiOSO₄⋅H₂O-Na₂SiO₃-NaOH-H₂O it was found that the formed titanosilicate solid phases differ both in composition and structure. The process of their aging under conditions of long-term exposure without forced heating is accompanied mainly by the loss of free water without noticeable structural and morphological changes. The exposure to the temperature of 70–100°С significantly accelerates the process of solid phase transformation. In these conditions, a porous system of particles is formed, which is confirmed by an increase in their specific surface area and total pore volume, as well as by an increase in the activity of the powders to absorb single- and double-charged cations. The effectiveness of hydrochloric acid treatment of fresh and especially aged precipitates on the ordering of the structure with the formation of crystals of a clear frame shape, inherent in the minerals zorite and ivanyukite, which contributes to increasing the sorption capacity of the final product is shown. The obtained results are used to adjust the technological regulations, which are used to test the technology of titanosilicate sorbent on the pilot plant.

Effect of early tranexamic acid treatment on fatigue in patients with mild traumatic brain injury: data from the CRASH-3 clinical trial

Background Each year world-wide about 65 million people sustain a mild traumatic brain injury (mTBI). Fatigue is a common and distressing symptom after mTBI. We examine the effect of tranexamic acid (TXA) on fatigue in patients with mTBI using data from the CRASH-3 trial. Methods The CRASH-3 trial randomised 9,202 patients with traumatic brain injury and no significant extracranial bleeding to receive TXA or placebo within 3 hours of injury. The primary outcome was death from head injury within 28 days of injury. The methods and results are presented elsewhere. Fatigue was recorded as “None”, “Moderate” or “Extreme.” This study examines the effect of TXA on extreme fatigue in the 2,632 patients with mTBI (Glasgow Coma Scale [GCS] score≥13). Our analyses were not prespecified. Results Our study primary outcome, extreme fatigue, was reported for 10 (0.8%) of 1,328 patients receiving TXA and 19 (1.5%) of 1,288 patients receiving placebo (risk ratio [RR]=0.51, 95% confidence interval [CI] 0.24-1.09). Death within 28 days of injury was reported for 34 (2.6%) of 1,328 patients receiving TXA versus 47 (3.6%) of 1,288 patients receiving placebo (RR=0.70, 95% CI 0.45-1.08). Among patients allocated to TXA, 44 (3.3%) patients either died or reported extreme fatigue versus 66 (5.1%) patients among those allocated to placebo (RR=0.65, 95% CI 0.44-0.94). This composite outcome is disproportionately influenced by deaths which account for 74% (81 from 110) of events. Conclusions We found no evidence that tranexamic acid reduces fatigue in patients with mTBI. Given, 1) our analyses were not prespecified, 2) our outcome measure is not based on a validated fatigue severity scale, and 3) TBI patients can suffer from hospital-induced delirium, which hinders clinician assessment, these results need to be replicated in another study.

Effects of Ursodeoxycholic Acid Treatment for Intrahepatic Cholestasis of Pregnancy on Maternal and Fetal Outcomes.

Intrahepatic cholestasis of pregnancy (ICP) appears in the second or third trimester of pregnancy and is characterized by pruritus and elevated blood bile acid (BA) levels. Complications from these symptoms may include preterm birth, fetal distress, or stillbirth. Although the precise causes of ICP are unknown, genetic, hormonal, and environmental variables may be involved. First-line treatment for ICP is ursodeoxycholic acid (UDCA), which improves bile flow and consequently lowers BA levels and pruritus. The objective of this study is to investigate the impact of UDCAtherapy on maternal and fetal outcomes in women with ICP. This was a prospective observational study of 123 pregnant women with ICP, aged between 20 and 45 years who were diagnosed clinically (pruritus) supported by abnormal laboratory results including elevated serum BA levels, and abnormalities in liver function tests, over the course of three years, from July 2021 to June 2024. Every patient received UDCA, commencing at 10-15 mg/kg/day and being titrated according to clinical guidelines. Maternal and fetal outcomes were tracked for the duration of the pregnancy, with data being collected at baseline (15 ± 1 weeks) and every two weeks until delivery. The mean age of the study participants was 29.6 ± 5.4 years, with the youngest patient being 20 years and the oldest being 45 years. Most womenwere multipara 65.9%, and the mean BMI was 27.8 ± 3.5 kg/m ². The mean time of gestational age at ICPdiagnosis was 31.2 ± 2.7 weeks, and the time of gestational age at delivery was 37.1 ± 2.4 weeks. On average, the serum BA level at diagnosis was 23.5 ± 8.1 µmol/L. In the majority of ICP patients with good fetal outcomes, UDCA not only normalizes serum BA levels but also reduces maternal symptoms. In addition to addressing patient response variability to this therapy and optimizing dissemination procedures, the researchers expect that the results of this study will support the continued use of UDCA as first-line treatment for ICP, at least until more evidence becomes available.

In vitro effects of ursolic acid on RANKL-induced osteoclast differentiation

Purpose: Ursolic acid is a small pentacyclic triterpene molecule composed of isoprenoid units. Although ursolic acid has been shown to be effective in the treatment of rheumatoid arthritis in many studies, very little research has been conducted on bone diseases caused by bone loss. The present study aimed to evaluate the effects of ursolic acid on osteoclast formation with the aim of finding herbal medicines that inhibit osteoclast function to strengthen bones and promote vitality in old age. Materials and Methods: RAW264.7 murine macrophages were used in our study and cells were treated with 100 ng/mL RANKL for osteoclastic differentiation. The effects of ursolic acid treatment on cell viability, tartrate-resistant acid phosphatase (TRAP) formation and osteoclastic gene expression levels were then measured. Results: Our results showed that ursolic acid did not exhibit significant cytotoxicity (3.2-9.8%) at concentrations of 2.5-10 µg/mL. Furthermore, ursolic acid inhibited osteoclast differentiation (15.2-39.1%) and suppressed the expression of osteoclastic genes such as cathepsin K (3.8-22.3%), TRAP (16.3-48. 7%), matrix metalloproteinase-9 (MMP-9) (10.7-40.2%), nuclear factor of activated T-cell cytoplasmic 1 (NFATc1) (1.2-29.7%), c-Fos (0.9-13.8%) and microphthalmia-associated transcription factor (MITF) (2.2-21.6%). Conclusion: Ursolic acid has been shown to inhibit RANKL-induced osteoclast differentiation and therefore we believe that ursolic acid may be used for the treatment and prevention of osteoporosis.

Assessment of the effect of ascorbic acid, sodium isoascorbate and calcium ascorbate treatments on the browning and wound healing process of fresh-cut potatoes

Browning significantly affects consumer perception, while texture hardening due to wound healing further reduces the commercial value of fresh-cut potatoes. This study evaluated the effects of 5 g L−1 ascorbic acid (AA), sodium isoascorbate (SI), and calcium ascorbate (CA) on browning and wound healing during ambient storage. The results indicated that AA and SI were more effective than CA and the control in delaying browning and wound healing. By day 3, browning levels in the AA and SI groups were reduced to 65 % and 62 % of the control, respectively, while lignin content decreased by 35 % and 40 %. Additionally, AA and SI treatments reduced reactive oxygen species (ROS) and improved antioxidant capacity, preserving appearance and texture. This study provides insights into the mechanisms of browning and wound healing, suggesting potential strategies for extending the shelf life and improving the quality of fresh-cut potatoes.

The Effect of Levetiracetam and Valproic Acid Treatment on Anger and Attention Deficit Hyperactivity Disorder Clinical Features in Children and Adolescents with Epilepsy: A Prospective Study.

Antiseizure medications (ASMs) can potentially trigger psychobehavioral adverse events associated with the onset or exacerbation of psychiatric symptoms such as irritability, aggression, and hyperactivity. The objective of this study was to evaluate the effects of levetiracetam and valproic acid on changes in clinical features of anger, attention deficit hyperactivity disorder (ADHD), and oppositional defiant disorder (ODD). The purpose was to furnish guidance on rational drug selection in children and adolescents with epilepsy to minimize psychiatric comorbidity in the treatment of epilepsy. This was a prospective, observational, cohort study involving treatment-naïve children aged 7-18 years with newly diagnosed generalized or focal epilepsy who were prescribed levetiracetam or valproic acid as monotherapy for a 6-month period and regularly followed up. Psychiatric assessment was conducted at the time of the new epilepsy diagnosis and at the six-month follow-up. These assessments were performed using the Schedule for Affective Disorders and Schizophrenia for School-Age Children Current and Lifetime Version (DSM-5), a structured psychiatric interview, as well as the State-Trait Anger Expression Style Inventory and Turgay DSM-IV Based Disruptive Behaviour Disorders Screening and Rating Scale. Anger subscores, ADHD symptoms, change in diagnosis, focal and generalized epilepsy groups, continuous seizures and seizure-free periods before and 6 months after treatment with valproic acid and levetiracetam were compared. A total of 50 children, 25 in the valproic acid group and 25 in the levetiracetam group, with a mean age of 11.92 ± 3.08 years, were included in the study. There was a statistically significant increase in the ADHD subscale score post-treatment among patients receiving levetiracetam (p = 0.045) and valproic acid (p = 0.034) compared with pre-treatment. The change in both anger-in and anger-out expression scores with treatment was significantly higher in patients receiving levetiracetam (p = 0.035) compared with those receiving valproic acid (p = 0.026). Statistically, there was a significant difference in the diagnostic criteria of the levetiracetam group pre- and post-treatment (p = 0.026). The proportion of patients in whom the diagnostic criteria for ADHD+ODD were fulfilled increased from 16% before treatment to 48% after treatment, a statistically significant increase (p = 0.026). This study found an increase in internalized anger features and ADHD symptom severity in children with epilepsy treated with valproic acid and levetiracetam. In those prescribed levetiracetam, there was a statistically significant rise in the proportion meeting the diagnostic criteria for ADHD + ODD. Our research is one of the first to prospectively examine the psychiatric assessment of children diagnosed with epilepsy. The remarkable results demonstrate changes in psychiatric diagnoses associated with the treatment of levetiracetam and valproic acid. Furthermore, a considerable rise in ADHD symptoms was observed in those treated with valproic acid.

Hydrothermal synthesis of bare TiO2 nanowires and polystyrene (PS)-TiO2 nanowires used for selective photocatalytic oxidation of 3-pyridinemethanol in water and PS photodegradation in solid state

In the present work, nanowire (NW) structured TiO2 nanoparticles were prepared using the hydrothermal method and characterized by X-Ray Diffraction (XRD), Scanning Electron Microscope (SEM), and BET specific surface area techniques. They were obtained in the anatase phase and presented a high surface area (ca. 300 m2/g). A commercial TiO2 (anatase, Merck) was used for comparison. The TiO2 catalysts were tested for photocatalytic oxidation of 3-pyridinemethanol to 3-pyridinemethanal and vitamin B3 in water under UVA irradiation. The effects of acid treatment and subsequent calcination for TiO2 catalysts after the hydrothermal synthesis were also investigated. The sample, subjected to acid treatment and calcined at 300 °C (NW-HCl-300), showed the highest photocatalytic activity and selectivity towards the products. Consequently, this sample and Merck TiO2 were used to prepare polystyrene (PS)/TiO2 composites using the hydrothermal method. They were characterized by XRD, SEM–EDX, Nuclear Magnetic Resonance (NMR), Fourier Transform Infrared Spectroscopy (FT-IR), Thermogravimetric analysis (TGA), Differential Scanning Calorimetry (DSC), UV–Vis, Gel Permeation Chromatography (GPC), and contact angle measurements and tested for PS (present in the composite) photodegradation. The results indicated that NW-HCl-300 had a high surface area, and was highly hydroxylated, favouring a good distribution of PS in the composite. The composite presented high thermal stability, but under UVA irradiation the polymer underwent solid-state photocatalytic degradation due to the contact with TiO2. The composite photodegradation was investigated using gravimetric, GPC, FT-IR, UV–Vis, and SEM techniques.

Molecular dynamics simulation of interfacial interaction mechanisms between ground tire rubber and styrene-butadiene rubber enhanced by nanomaterial incorporation

The recycling of ground tire rubber (GTR) is an effective method for addressing black pollution. In this study, we investigated and compared the effects of acidic oxidation treatments and different nanomaterial contents on the interfacial properties of styrene-butadiene rubber (SBR) and GTR. Molecular models of GTR modified by acidic oxidation and nanomaterials, as well as SBR, were established. The interfacial interaction mechanisms between SBR and GTR were studied through tensile and shear behaviors. The results indicated that the properties of SBR-GTR interface were enhanced through acidic oxidation and nanomaterial modification, with the latter demonstrating superior advantages in augmenting the interfacial strength. Specifically, the addition of a carbon nanotube and graphene increased the interfacial cohesion strength by 55.12 % and 82.93 %, and the interfacial shear strength by 29.87 % and 43.05 %, respectively. Moreover, graphene exhibited superior performance in enhancing interfacial interactions compared to carbon nanotubes and increasing the nanomaterial content did not positively impact the improvement of interfacial properties. The interfacial properties of SBR and GTR were quantitatively analyzed using molecular dynamic (MD) simulations. This study provides a theoretical foundation for enhancing the mechanical properties of recycled rubber by using nanomaterials, thereby guiding the experimental preparation of recycled rubber.

Effect of early tranexamic acid treatment on fatigue in patients with mild traumatic brain injury: data from the CRASH-3 clinical trial.

Each year world-wide about 65 million people sustain a mild traumatic brain injury (mTBI). Fatigue is a common and distressing symptom after mTBI. We examine the effect of tranexamic acid (TXA) on fatigue in patients with mTBI using data from the CRASH-3 trial. The CRASH-3 trial randomised 9,202 patients with traumatic brain injury and no significant extracranial bleeding to receive TXA or placebo within 3 hours of injury. The primary outcome was death from head injury within 28 days of injury. The methods and results are presented elsewhere. Fatigue was recorded as "None", "Moderate" or "Extreme." This study examines the effect of TXA on extreme fatigue in the 2,632 patients with mTBI (Glasgow Coma Scale [GCS] score≥13). Our analyses were not prespecified. Our study primary outcome, extreme fatigue, was reported for 10 (0.8%) of 1,328 patients receiving TXA and 19 (1.5%) of 1,288 patients receiving placebo (risk ratio [RR]=0.51, 95% confidence interval [CI] 0.24-1.09). Death within 28 days of injury was reported for 34 (2.6%) of 1,328 patients receiving TXA versus 47 (3.6%) of 1,288 patients receiving placebo (RR=0.70, 95% CI 0.45-1.08). Among patients allocated to TXA, 44 (3.3%) patients either died or reported extreme fatigue versus 66 (5.1%) patients among those allocated to placebo (RR=0.65, 95% CI 0.44-0.94). This composite outcome is disproportionately influenced by deaths which account for 74% (81 from 110) of events. We found no evidence that tranexamic acid reduces fatigue in patients with mTBI. Given, 1) our analyses were not prespecified, 2) our outcome measure is not based on a validated fatigue severity scale, and 3) TBI patients can suffer from hospital-induced delirium, which hinders clinician assessment, these results need to be replicated in another study.

Effects of alfa lipoic acid and coenzyme Q10 treatment on AFB1-induced oxidative, inflammatory, and DNA damages in rats

Food contamination with Aflatoxin B1 (AFB1) is a worldwide concern that adversely affects animal and human health. The study aimed to evaluate the protective effect of alpha lipoic acid (ALA) and/or co-enzyme Q10 (CQ10) against the harmful effects of AFB1 on the liver and kidneys. Fifty-six mature male Wistar Albino rats (180–200 g) were divided into seven groups, each with eight rats: (1) saline was given as a control, (2) ALA (100 mg/kg bw/day) was given by stomach gavage for fifteen days, and (3) CQ10 (10 mg/kg bw/day) was given by stomach gavage for fifteen days. Group (4) orally given AFB1 (2.5 mg/kg bw) on days 12th and 14th, (5) received AFB1 and ALA, (6) received AFB1 and CQ10, and (7) received AFB1, ALA, and CQ10, as previously described in the ALA, CQ10, and AFB1 groups. After the exposure to AFB1, a significant increase in liver markers (AST, ALT, ALP, and LDH) and renal function tests (BUN and creatinine) was observed compared with the control. ALA and/or CQ10 significantly reduced enzymes of liver and renal functions, as compared with AFB1. AFB1 exposure threw off the balance between oxidants and antioxidants. Still, ALA and/or CQ10 made oxidative stress (MDA, NO, and 8-OHdG) much lower and antioxidant activities (GSH, GSH-Px, SOD, and CAT) much higher. When we used the two together, the activities matched the control levels. Interestingly, this study shows that ALA and CQ10 significantly lowered IL-1β, IL-6, and TNF-α levels compared to the control values when used together after AFB1 exposure caused robust inflammation. Some CQ10 treatment parameters significantly outperformed those of ALA. ALA and CQ10 together worked better than either one alone to protect against AFB1-induced toxicity in the hepatic and renal parenchyma in terms of reducing inflammation, preventing DNA damage, and fighting free radicals.

Investigation of models for predicting the effectiveness of acid treatments in carbonate deposits

This article presents the results of an analysis of the available literature data on the acid treatment of carbonates based on the solution approach. The analysis of various acid treatment liquids, the choice of additives and modeling procedures was also carried out in order to optimally design the process of acid treatment of carbonates. Although theoretical models are designed to predict the effectiveness of acid treatments, their practical applicability for scaling at the field level remains uncertain. Scaling laboratory data to the optimal rate does not always lead to results corresponding to the usual values of processing at the field. In modern models, it is proposed to use the geometry of the pipe to calculate the dominant penetration of wormholes and take into account the competition between them, introducing the density of wormholes in a porous medium. However, assigning values that are sensitive to the rock structure and injection conditions is a major difficulty. Instead of predicting the length of dominant wormholes, it is preferable to focus on estimating the permeability resulting from acid injection. However, the permeability assessment is not possible without first calculating the dissolution coefficient. The simulation results demonstrate that the existence of various zones of recesses or cracks in the formation has a significant impact on the acidification process, especially on the direction of wormhole propagation. This direction can be partially controlled by adding deflecting or retarding agents.

Gibberellin Inhibitors Molecules as a Safeguard against Secondary Growth in Garlic Plants

Secondary growth in garlic depreciates its visual aspect and thereby renders the crop unviable for trade. Therefore, farmers commonly reduce fertilization and impose drought and oxidative stress caused by high-dose pesticides to reduce secondary growth in garlic plants. However, these procedures can be considered adverse, unhealthy, and environmentally inappropriate. To remedy this scenario, we investigated whether spraying growth inhibitors would prevent secondary growth in garlic plants. First, we evaluated the effects of abscisic acid, trinexapac-ethyl, chlormequat chloride, and paclobutrazol treatments on garlic plants grown in polyethylene tanks (250 m3). We then analyzed the effects of deficit irrigation combined with the application of trinexapac-ethyl (sprayed two or three times) and the application of trinexapac-ethyl, chlormequat chloride, or paclobutrazol alone (each sprayed two or three times) on garlic plants grown in the field, comparing them with the effects of deficit irrigation (control treatment) alone. The in-field experiment was replicated with the following treatments: control (deficit irrigation) and trinexapac-ethyl (sprayed two or three times) treatments. We analyzed the physiological, biometric, and production parameters affecting secondary growth in garlic plants. We observed that trinexapac-ethyl could efficiently regulate secondary growth without causing physiological disturbances in garlic plants. Our results provide valuable information that will contribute to the development of a sustainable technique to replace the current practices used by farmers to prevent secondary growth in garlic plants.

Modulating rice digestibility: Mechanisms of ultrasound, oleic acid and moist-heat treatments influence structural, physicochemical and digestive properties

The research compared the combined effect of ultrasound (160 W, 2 min), oleic acid (15%, 11 h), and moist-heat treatment (HMT, 25% moisture content, 110 °C, 2 h) with their individual treatment on rice grains. The results showed that ultrasound treatment created pores and cracks in the rice grains, facilitating an easier penetration for oleic acid to develop amylose-oleic acid complex during HMT. Compared to native raw rice (NR), both single and combined treatments significantly altered the morphology, reduced swelling power and solubility, enhanced hydrophilicity, thus changing the moisture distribution, thermal and pasting characteristics. Notably, the combined treatment of three techniques significantly increased the relative crystallinity, accompanied by the highest digestive resistance, and the content of resistant starch was increased from 20.53% in NR to 31.75%, much higher than the other treatments. These findings provide potential for the manufacturers to rationally and flexibly employ this low digestible rice in health food products.

The effect of intrahepatic cholestasis of pregnancy and ursodeoxycholic acid treatment on Doppler parameters of fetal and maternal circulation.

We aimed to evaluate feto-maternal blood flow parameters using Doppler ultrasonography (USG) in pregnant women with intrahepatic cholestasis of pregnancy (ICP) and the effect of ursodeoxycholic acid (UDCA) treatment on these parameters. This prospective cohort study was performed at Dr. Sami Ulus Women's and Children's Health Teaching and Research Hospital, in Turkey between September 2022 and February 2023. Sixty pregnant women, 30 with ICP disease and 30 healthy women were included in the study. Obstetric Doppler parameters were measured by USG at diagnosis and after 48 hours of UDCA treatment for the ICP group. The obstetric Doppler parameters did not significantly differ in the ICP group and the healthy control group. The Doppler findings were similar after UDCA treatment in the ICP group. Gestational week at delivery and birth weight were lower in the ICP group in our study. We demonstrated that pregnant women with ICP had similar obstetric Doppler parameters when compared with healthy pregnant women and that the UDCA agent used for treatment of ICP disease did not affect these parameters.
