This study aimed to verify the efficacy of low-level laser irradiation (LLLI) on the proliferation of MC3T3-E1 preosteoblasts cultured on poly(lactic acid) (PLA) films. The produced films were characterized by contact angle tests, scanning electron microscopy (SEM), atomic force microscopy, differential scanning calorimetry, and X-ray diffraction. The MC3T3-E1 cells were cultured as three different groups Control-cultured on polystyrene plastic surfaces; PLA-cultured on PLA films; and PLA + Laser-cultured on PLA films and submitted to laser irradiation (660 nm; 30 mW; 4 J/cm2 ). Cell proliferation was analyzed by Trypan blue and Alamar blue assays at 24, 48, and 72 h after irradiation. Cell viability was assessed by Live/Dead assay, apoptosis-related events were evaluated by Annexin V/propidium iodide (PI) expression, and cell cycle events were analyzed by flow cytometry. Cell morphology on the surface of films was assessed by SEM. Cell counting and biochemical assay results indicate that the PLA + Laser group exhibited higher proliferation (p less then 0.01) when compared with the Control and PLA groups. The Live/Dead and Annexin/PI assays indicate increased cell viability in the PLA + Laser group that also presented a higher percentage of cells in the proliferative cell cycle phases (S and G2/M). These findings were also confirmed by the higher cell density observed in the irradiated group through SEM images. The evidence from this study supports the idea that LLLI increases the proliferation of MC3T3-E1 cells on PLA surfaces, suggesting that it can be potentially applied in bone tissue engineering.
Knowledge of sequential changes in haematobiochemical parameters of infected animals helps in the formulation of appropriate supportive therapy.

We investigated the sequential haematological and biochemical changes in peste des petits ruminants (PPR)-infected Black Bengal goats.

Goats were either infected with PPR virus (PPRV; n=8) or sham infected with sterile phosphate-buffered saline (n=4) via the intranasal route. Blood and sera were collected from both groups at different days post-infection (dpi) and analysed. Goats were sacrificed at different dpi and the amount of PPRV RNA in different tissues was quantified by real-time RT-PCR.

The PPRV-infected goats showed mild depression and scanty nasal secretions starting at 4 dpi which became severe with high fever (106°F), dyspnoea, stomatitis, profuse orinasal discharge and diarrhoea at 9-13 dpi. this website PPRV RNA was detected in different tissues of infected goats. Severe lymphocytic leukopenia (at 18 dpi) was observed in infected goats. Total protein and albumin decreased in infected goats starting at 10 dpi. An elevated level of enzymes (alkaline phosphatase, creatine kinase, aspartate transaminase and alanine transaminase) and metabolites (blood urea nitrogen and urea B) were found in infected goats starting at 7-10 dpi, suggesting damages in the liver and kidneys. PPR-infected goats showed elevated sodium and chloride ions starting at 7 dpi. The majority of infected goats were seroconverted by 14 dpi.

Anti-diarrheal agents, aqua solutions and other medicine to support liver and kidney functions could be considered as supportive therapy against PPRV infection.

As a low-carbohydrate diet and the use of sodium-glucose transporter-2 inhibitors are both known to increase D-beta-hydroxybutyrate levels, the effect of these levels on glucose metabolism has attracted attention. We investigated the acute effects of ketone monoester (KM) ingestion on blood glucose levels during the 75-g oral glucose tolerance test (OGTT) in participants with impaired glucose tolerance.

Nine Japanese adults aged 48-62years (4 men, 5 women) with impaired glucose tolerance participated in this study. After participants fasted overnight, we carried out OGTT for 180min with and without KM ingestion on two separate days in a randomized cross-over design. We compared the area under the curve (AUC) of D-beta-hydroxybutyrate, glucose, insulin, C-peptide, glucagon and free fatty acids during OGTT.

The AUC of D-beta-hydroxybutyrate during OGTT was significantly higher with KM than without KM (KM 5995.3±1257.1mmol/L·h; without KM 116.1±33.9mmol/L·h, P<0.0001), and the AUC of glucose with KM was significantly lower than that without KM (KM 406.6±70.6mg/dL·h; without KM 483.2±74.3mg/dL·h, P<0.0001). This improved glucose excursion was associated with enhanced AUC of insulin during the first half (0-90min) of OGTT, even though the AUC of C-peptide during this period was unchanged. In contrast, the AUC of insulin, C-peptide, glucagon and free fatty acids during 180min of OGTT were similar in both conditions.

The ingestion of KM decreased the AUC of glucose during 75-g OGTT in Japanese individuals with impaired glucose tolerance, and the mechanism might involve elevated levels of circulating early phase insulin.

Until recently, published research about group antenatal care did not represent findings from low- and middle-income countries, which have health priorities, system challenges, and opportunities that are different than those in high-income countries. Because high-quality evidence is limited, the World Health Organization recommends group antenatal care be implemented only in the context of rigorous research. In 2016 the Global Group Antenatal Care Collaborative was formed as a platform for group antenatal care researchers working in low- and middle-income countries to share experiences and shape future research to accelerate development of a robust global evidence base reflecting implementation and outcomes specific to low- and middle-income countries. This article presents a brief history of the Collaborative's work to date, proposes a common definition and key principles for group antenatal care, and recommends an evaluation and reporting framework for group antenatal care research.
