ABSTRACT

This study investigated the development of biodegradable films made from a combination of carboxymethyl cellulose (CMC), Polyvinyl alcohol (PVA), and purified extract of broccoli sprout seed (BSSE). The films were characterized for their color, physical properties, surface morphology, crystallinity, mechanical properties, and thermal properties. The addition of BSSE up to 1.4 % to the film matrix imparted opaque color and increased opacity up to 3.652. The films also became less moisture-absorbent 8.21 %, soluble 19.16 %, and permeable to water vapor 1.531 (× 10-10 g.m-1 s-1 pa-1). By utilizing 0.7 % from BSSE inside films, the surface of the films became smoother but became rough with higher concentrations 2.1 % of BSSE. Fourier transform infrared (FT-IR) analysis showed that there was physical interaction between the BSSE extract and the PV/CM matrix. The films showed good thermal stability, and the incorporation of BSSE improved their ability to preserve the acidity, TBARS, peroxide value, and total color differences of butter during cold storage.

ABSTRACT

BACKGROUND: Three different organic sunflower seed cakes, produced from seeds differing in the content of their hulls, were extracted by two different extraction methods - conventional extraction (CE) and ultrasound-assisted extraction (UAE). The total phenolic compound (TPC) content of the extracts was evaluated using Folin-Ciocâlteu reagent (FCR) and high-performance liquid chromatography (HPLC). The antioxidant capacity of extracts was evaluated with the Trolox equivalent antioxidant capacity (TEAC) and 2,2-diphenyl-1-picrylhydrazyl (DPPH) assays. RESULTS: The results showed that both extracts displayed high TPC content and antioxidant capacity. The UAE method showed significantly higher TPC content and antioxidant capacity values than CE. Individual phenolic compounds such as chlorogenic acid (CGA) isomers (3-, 4- and 5-O-caffeoylquinic acids), di-CGA isomers, and feruloylquinic and coumaroylquinic acids were identified according to their exact masses by HPLC coupled to time-of-flight mass spectrometry. CONCLUSION: The results revealed that the UAE method could be used effectively to facilitate the extraction of phenolic compounds from sunflower seed cake. © 2023 The Authors.

ABSTRACT

Objective/Background: The abdominal muscles are extremely important in stabilizing the trunk and maximizing postural stability. The presence of apparent stiffness in children with spastic diplegia is associated with unsteadiness, impaired walking, and pelvic malrotation. The aim of this study was to compare the efficacy of hippotherapy and whole-body vibration in ameliorating abdominal muscle thickness and sitting function in children with diplegia. Methods: A total of 60 children with spastic diplegia were selected from the Faculty of Physical Therapy's outpatient clinic, Cairo University, and randomly allocated into two groups. Group A received conventional physical therapy for 1 h in addition to whole-body vibration, whereas group B received hippotherapy for 40 min. The same designed physical therapy program was administered for 12 weeks, three times per week, in both groups. Ultrasonography was used to measure abdominal thickness, and Gross Motor Function Measurement-88 was used to measure functional ability. Results: A significant improvement in abdominal muscle thickness and sitting function (p < 0.05) was observed in both groups, and greater improvements were observed in group B. Conclusion: Whole-body vibration and hippotherapy training may be recommended to facilitate sitting function and ameliorate abdominal thickness in children with diplegia. Hippotherapy is more effective than whole-body vibration in improving sitting function and abdominal muscle thickness.

ABSTRACT

Vitiligo is a chronic disorder of depigmentation that has different treatment modalities, but patients' nonadherence is common. This study aimed to assess the influence of patients' medication beliefs on patients' adherence to topical, oral medications, and phototherapy in vitiligo. Between September 2015 and February 2016, 260 patients with vitiligo were asked to fill in the Beliefs about Medicines Questionnaire (BMQ) to assess their beliefs about therapy for vitiligo. Their adherence to the therapy was examined using the 8-item Morisky Medication Adherence Scale (MMAS-8). RESULTS: The MMAS-8 scale and BMQ had good internal consistency (Cronbach's α = 0.78 and 0.66, respectively). Using Morisky's recommended cutoff point, 71% of patients were categorized as low or nonadherent to the scheduled therapy. Patients who perceived specific necessity of dermatological medicines significantly adhered to their therapy (OR 1.23; 95% CI 1.09, 1.38; p = 0.001) whereas patients who had specific concerns about the adverse effects exhibited significant low adherence (OR 0.65; 95% CI 0.56, 0.76; p < 0.001). CONCLUSION: Positive beliefs about the necessity of medications in vitiligo do not necessarily reflect high adherence. Patients' adherence behavior is a multidimensional and dynamic process. The prolonged course of treatment, its cost, and unsatisfactory outcomes influenced the patients' adherence.

ABSTRACT

The objective of this study was to investigate the effect of polypharmacy and high doses of amoxicillin/clavulanate on warfarin response in hospitalized patients. This was a prospective cross-sectional observational study on 120 patients from July 2013 to January 2014. Potentially interacting drugs were classified according to their tendency of increasing international normalized ratio (INR) or bleeding risk. The 87.5% of patients prescribed high-dose amoxicillin/clavulanate (10-12 g daily) compared with 28.9% of patients prescribed a normal dose (up to 3.6 g daily) had INR values ≥ 4 during the hospital stay (P ≤ .001). Increased number of potentially interacting drugs that are known to increase INR was a significant predictor of having INR values ≥ 4 (OR, 2.5; 95%CI, 1.3-4.7), and increased number of potentially interacting drugs that are known to increase bleeding risk was a significant predictor of experiencing bleeding episodes (OR, 3.1; 95%CI, 1.3-7.3). High doses of amoxicillin/clavulanate were associated with a higher risk of over-anticoagulation when combined with warfarin than were normal doses. Increased risk of having INR ≥ 4 and bleeding events was associated with increased numbers of potentially interacting drugs prescribed, indicating that polypharmacy is a problem of concern. Frequent monitoring of warfarin therapy along with patients' medications is necessary to avoid complications.

ABSTRACT

There is interest in the potential of cocoa flavanols, including monomers and procyanidins, to prevent obesity and type-2 diabetes. Fermentation and processing of cocoa beans influence the qualitative and quantitative profiles of individual cocoa constituents. Little is known regarding how different cocoa flavanols contribute to inhibition of obesity and type-2 diabetes. The objective of this study was to compare the impacts of long-term dietary exposure to cocoa flavanol monomers, oligomers, and polymers on the effects of high-fat feeding. Mice were fed a high-fat diet supplemented with either a cocoa flavanol extract or a flavanol fraction enriched with monomeric, oligomeric, or polymeric procyanidins for 12 weeks. The oligomer-rich fraction proved to be most effective in preventing weight gain, fat mass, impaired glucose tolerance, and insulin resistance in this model. This is the first long-term feeding study to examine the relative activities of cocoa constituents on diet-induced obesity and insulin resistance.

ABSTRACT

A suitable vehicle for integration of bioactive plant constituents is proposed. It involves modification of proteins using phenolics and applying these for protection of labile constituents. It dissects the noncovalent and covalent interactions of ß-lactoglobulin with coffee-specific phenolics. Alkaline and polyphenol oxidase modulated covalent reactions were compared. Tryptic digestion combined with MALDI-TOF-MS provided tentative allocation of the modification type and site in the protein, and an in silico modeling of modified ß-lactoglobulin is proposed. The modification delivers proteins with enhanced antioxidative properties. Changed structural properties and differences in solubility, surface hydrophobicity, and emulsification were observed. The polyphenol oxidase modulated reaction provides a modified ß-lactoglobulin with a high antioxidative power, is thermally more stable, requires less energy to unfold, and, when emulsified with lutein esters, exhibits their higher stability against UV light. Thus, adaptation of this modification provides an innovative approach for functionalizing proteins and their uses in the food industry.
