AIM: To investigate the potential therapeutic effect of exopolysaccharide (EPS)-producing Streptococcus thermophilus (S. thermophilus) CRL 1190 fermented milk on chronic gastritis in Balb/c mice. METHODS: Balb/c mice were fed with the fermented milk for 7 d after inducing gastritis with acetyl-salicylic acid (ASA, 400 mg/kg body weight per day for 10 d). Omeprazole was included in this study as a positive therapeutic control. The gastric in? ammatory activity was evaluated from gastric histology and in? ammation score, number of interleukin-10 (IL-10), interferon-γ (INFγ) and tumor necrosis factor-α (TNF-α) cytokine-producing cells in the gastric mucosa, and thickness of the mucus layer. RESULTS: Animals receiving treatment with the EPS-producing S. thermophilus CRL 1190 fermented milk showed a conserved gastric mucosa structure similar to that of healthy animals. In? ammation scores of the fermented milk-treated mice were lower than those of mice in the gastritis group (0.2 ± 0.03 vs 2.0 ± 0.6, P < 0.05). A marked decrease in INFγ+ (15 ± 1.0 vs 28 ± 1.2, P < 0.05) and TNF-α+ (16 ± 3.0 vs 33 ± 3.0, P < 0.05) cells and an increase in IL-10+ (28 ± 1.5 vs 14 ± 1.3, P < 0.05) cells compared to the gastritis group, was observed. Also, an increase in the thickness of the mucus gel layer (2.2 ± 0.6 vs 1.0 ± 0.3; 5.1 ± 0.8 vs 1.5 ± 0.4 in the corpus and antrum mucosa, respectively, P < 0.05) compared with the gastritis group was noted. A milk suspension of the purif ied EPS from S. thermophilus CRL1190 was also effective as therapy for gastritis.

A robust methodology for the quantitative assessmentof the rat jawbone microstructure

International Journal of Oral Science 2017年第2期9卷 87-94页

Micro-computed tomography can be applied for the assessment of the micro-architectural characteristics of the cortical and trabecular bones in either physiological or disease conditions. However, reports often lack a detailed description of the methodological steps used to analyse these images, such as the volumes of interest, the algorithms used for image filtration, the approach used for image segmentation, and the bone parameters quantified, thereby making it difficult to compare or reproduce the studies. This study addresses this critical need and aims to provide standardized assessment and consistent parameter reporting related to quantitative jawbone image analysis. Various regions of the rat jawbones were screened for their potential for standardized micro-computed tomography analysis. Furthermore, the volumes of interest that were anticipated to be most susceptible to bone structural changes in response to experimental interventions were defined. In the mandible, two volumes of interest were selected, namely, the condyle and the trabecular bone surrounding the three molars. In the maxilla, the maxillary tuberosity region and the inter-radicular septum of the second molar were considered as volumes of interest. The presented protocol provides a standardized and reproducible methodology for the analysis of relevant jawbone volumes of interest and is intended to ensure global, accurate, and consistent reporting of its morphometry. Furthermore, the proposed methodology has potential, as a variety of rodent animal models would benefit from its implementation.

Pine-fruit shell (PFS) is a lignocellulosic residue derived from the fruit of Araucaria angustifolia, a coniferoustree native of South America, part of a whole vegetation of the Atlantic Forest, found in the South and Southwestof Brazil. In this work PFS will be characterized and used in the production of PFS-based polyols throughoxypropylation. Three series were chosen (PFS/propylene oxide (PO) (w/v, g/mL) of 30/70, 20/80 and 10/90)with four catalyst levels (5%, 10%, 15% and 20%, (w/w, PFS based)). Oxypropylation occurred at moderateconditions of temperature, pressure and time giving rise to liquid polyols with a homopolymer content (PPO)ranging from 4-65%, a hydroxyl number (IOH) between 257-605 mg KOH/g and viscosities (V) varying from0.76 Pa.s to 373.90 Pa.s (20°C) for the series 20/80 and 10/90, while for the series 30/70, the viscosity reachedvalues higher than 500 Pa.s, 20°C. The unreacted PFS (UR) varied between 3.6% and 77.4% (PFS-basis). Afterthe PFS-based polyols production and characterization, a principal component analysis (PCA) was performed inorder to evaluate the established interactions between the used formulation variables and the obtained polyolproperties. The PCA analysis allowed to clarify the interactions between PFS and PO contents and the finalbiopolyol properties (PPO, IOH, V and UR). This approach showed to be a simple method to rationally analyzethe influence of the input formulation variables on the final polyol properties.

Trauma to the peripheral nervous system often results in loss of motor and sensory functions of the affected area of the body,leading to a series of functional impairments(Allodi et al.,2012).Injuries to peripheral nerves initiate a series of complex events,known as Wallerian degeneration,which allows the injured axons to regenerate and reinnervate their targets(Allodi et al.,2012).Damage to a nerve induces multiple alterations,which include:axonal degeneration,breakdown of myelin sheath,Schwann cells(SC)proliferation and conversion to a repair phenotype which express cytokines and chemokines that allow the infiltration and activation of macrophages(Mietto et al.,2015;Jessen and Mirsky,2016).
