The food industry is challenged to develop nutritious and palatable foods that satisfy older people's needs. So, this work aimed to study the incorporation of nanoemulsions enriched with vitamin D and omega-3 fatty acids into two desserts (yogurt and fruit puree), characterizing their nutritional profile, viscosity, and color properties and evaluating their in vitro bioaccessibility and sensory response. The results showed that adding nanoemulsion modified the nutrition profile of desserts due to increasing lipids and calories.

Purpose Of Review: To present current evidence in long-term (> 5 years) results after endoscopic sinus surgery (ESS) focusing on Patients Reported Outcome Measures (PROMs) and other sinonasal outcomes while assessing the role of ESS in the treatment of CRSwNP, and identifying outcomes which affect the results of ESS and defining recommendations for future studies.

Recent Findings: Long-term results of ESS in CRSwNP can be branched in PROMs and other objective measurements. Despite the heterogeneity of reported outcomes make it difficult to perform comparisons and meta-analysis, ESS improves PROMs, including symptoms, QOL and olfaction.

Article Synopsis
  • Caligidosis, caused by copepod ectoparasites in salmon farming, poses a significant challenge due to their ability to adhere to fish skin using chitin filaments.
  • This study focused on antimicrobial peptides found in salmon mucosal secretions, finding that hepcidin and piscidin could bind to chitin, although piscidin showed hemolytic effects at lower concentrations.
  • Hepcidin effectively reduced the infestation of the nauplius II stage of the parasite by 50% at a concentration of 50 µM, suggesting that fish-derived antimicrobial peptides can target the exoskeleton of copepods and help combat parasitic issues in salmon farming.

Article Synopsis
  • The study examines how architectural design parameters of 3D-printed polymer scaffolds—specifically porosity, height-to-diameter (H/D) ratio, and pore size—affect their mechanical properties, particularly compressive strength.
  • Controlled experiments were conducted by varying these parameters, revealing that both porosity and H/D ratio significantly influence the apparent elastic modulus and bulk yield stress of the materials.
  • While pore size did not greatly affect mechanical properties, understanding these parameters can aid in optimizing bone scaffold development for better biomechanical performance.

The aim of this study was to understand the contribution of hydrocolloids to oral structure breakdown of starch-based systems in relation to mouthfeel sensations. For this, carrot purees were prepared using corn starch and a different second thickener (λ-carrageenan, carboxymethylcellulose (CMC), xanthan gum, or an extra amount of starch). The viscosity decay of purees under in vitro oral conditions was measured (starch pasting cell adapted to a rheometer) when shearing at a constant shear rate in the presence of artificial saliva.

A wide variety of medical imaging techniques pervade modern medicine, and the changing portability and performance of tools like ultrasound imaging have brought these medical imaging techniques into the everyday practice of many specialties outside of radiology. However, proper interpretation of ultrasonographic and computed tomographic images requires the practitioner to not only hone certain technical skills, but to command an excellent knowledge of sectional anatomy and an understanding of the pathophysiology of the examined areas as well. Yet throughout many medical curricula there is often a large gap between traditional anatomy coursework and clinical training in imaging techniques.

Due to the rheological and structural basis of texture perceived in semisolid foods, the aim of this work was to study the effects of two thickening agents, on rheology and microstructure of soy protein desserts. As rheological parameter values may not be enough to explain the possible perceived texture differences, the effect of composition on two instrumental indexes of oral consistency (apparent viscosity at 50 s(-1) and complex dynamic viscosity at 8 Hz) was also studied. Samples were prepared at two soy protein isolate (SPI) concentrations (6 and 8 % w/w), each with four modified starch concentrations (2, 2.

Low-fat foods are an interesting option for consumers interested in health-related issues or in maintaining adequate body weight; however, fat reduction may influence consumer acceptance of the end product. This study aims to obtain information about the effectiveness of λ-carrageenan and a blend (50:50) of short- and long-chain inulin as fat replacers in dairy beverages prepared with carboxymethyl cellulose (CMC) and to determine to what extent consumers perceive instrumental color and rheological differences among samples. Results showed that both λ-carrageenan and the inulin blend could be used as fat replacers in CMC-based dairy beverages and that consumers could distinguish among samples that differed in color and rheological behavior.
