The effect of nanoemulsions prepared with grape seed and cinnamon essential oils on the shelf-life of flathead mullet (Mugil cephalus) fillets was evaluated by determining physicochemical (pH, free fatty acids, peroxide value, total volatile base nitrogen (TVB-N), and thiobarbituric acid reactive substances (TBARs)), sensory and microbiological (mesophilic aerobic bacteria, total psychrophilic bacteria, and Enterobacteriaceae counts) properties during 14 day storage at 2 °C.

The nanoemulsions showed good stability and low average droplet size. The results indicated that nanoemulsion treatments significantly prolonged the shelf-life of the fillets. Treatment inhibited increases in pH and TVB-N, and retarded lipid oxidation and hydrolysis. Sensory assessment revealed that treatment induced shelf-life extension from 10 to 14 days, compared with controls. Microbiological analyses showed nanoemulsion treatment caused shelf-life extension from 10 to 12 days with reduction of microbiological contamination by up to 1 log cfu g

in mesophilic and 1.5 log cfu g

in psychrotrophic bacteria.

Considering the results, grape seed and cinnamon essential oil nanoemulsions could be considered as novel antimicrobial and antioxidant materials for shelf-life extension of flathead mullet fillets during cold storage. © 2021 Society of Chemical Industry.

This cross-sectional, observational study examined the prevalence of objectively measured chronic disease risk factors among a diverse group of food pantry patrons.

Public health nurses performed biometric screenings in community settings for 1,685 unduplicated adults attending food pantries.

Over three fourths of participants (81.1%) were overweight or obese. High cholesterol and high blood pressure were detected in 38.4% and 37.7% of participants, respectively. https://www.selleckchem.com/products/apr-246-prima-1met.html Over half (58%) of the participants were referred to a local community health clinic for follow-up services.

Interventions should target food pantry patrons to reduce the prevalence of chronic disease conditions among this vulnerable population.

Recently, bulk perovskites have been employed as sensitizers in solid-state upconversion devices to circumvent poor exciton diffusion in previous nanocrystal (NC)-sensitized devices. However, an in-depth understanding of the underlying photophysics of perovskite-sensitized triplet generation is still lacking due to the difficulty of precisely controlling interfacial properties of fully solution-processed devices. In this study, interfacial properties of upconversion devices are adjusted by a mild surface solvent treatment, specifically altering perovskite surface properties without perturbing the bulk perovskite. Thermal evaporation of the annihilator precludes further solvent contamination. Counterintuitively, devices with more interfacial traps show brighter upconversion. Approximately an order of magnitude difference in upconversion brightness is observed across different interfacial solvent treatments. Sequential charge transfer and interfacial trap-assisted triplet sensitization are demonstrated by comparing upconversion performance, transient photoluminescence dynamics, and magnetic field dependence of the devices. Incomplete triplet conversion from transferred charges and consequent triplet-charge annihilation (TCA) are also observed. The observations highlight the importance of interfacial control and provide guidance for further design and optimization of upconversion devices using perovskites or other semiconductors as sensitizers.A method for the estimation of coordinates of atoms in proteins from coarse-grained geometry by simple analytical formulas (ESCASA), for use in nuclear-magnetic-resonance (NMR) data-assisted coarse-grained simulations of proteins is proposed. In this paper, the formulas for the backbone Hα and amide (HN ) protons, and the side-chain Hβ protons, given the Cα -trace, have been derived and parameterized, by using the interproton distances calculated from a set of 140 high-resolution non-homologous protein structures. The mean standard deviation over all types of proton pairs in the set was 0.44 Å after fitting. Validation against a set of 41 proteins with NMR-determined structures, which were not considered in parameterization, resulted in average standard deviation from average proton-proton distances of the NMR-determined structures of 0.25 Å, compared to 0.21 Å obtained with the PULCHRA all-atom-chain reconstruction algorithm and to the 0.12 Å standard deviation of the average-structure proton-proton distance of NMR-determined ensembles. The formulas provide analytical forces and can, therefore, be used in coarse-grained molecular dynamics.

The aim of this clinical trial was to evaluate the effect of a periodontal health education session (PHES), which included education on the pathogenesis and consequences of periodontal diseases on oral hygiene motivation in patients with gingivitis.

A randomized controlled clinical trial was conducted on 50 (26 females and 24 males) patients with gingivitis who underwent periodontal treatment. Subjects were randomly allocated into the PHES group (experimental group) and standard oral hygiene education group (control group). The Rustogi Modified Navy Plaque Index (RMNPI) and Papillary Bleeding Index (PBI) were used to evaluate oral hygiene at baseline and were repeated after 1, 3, and 6 months. Knowledge about periodontal disease was measured and the participants' motivation was determined using the Oral Hygiene Motivation Scale.

Although baseline knowledge levels and motivation scores were not different between the groups, following the educational motivational interviewing (MI) session, levels were higher in the experimental compared with the control group.
