Osteoblasts were treated with Dex (100 µM) with or without Table (5 or 10 µM). We measured cell viability, alkaline phosphatase (ALP) activity, and mitochondrial superoxide and reactive oxygen species levels. Piperaquine We used flow cytometry to explore the effects of Tab on mitochondrial membrane potential and osteoblast apoptosis. We used RT-PCR and western blotting to examine the effect of Tab on protein expression. We evaluated the effects of Tab on bone histopathology and bone mineral density in rats with Dex-induced osteoporosis. Tab increased cell viability and ALP activity, and reduced the mitochondrial superoxide, reactive oxygen species and matrix metalloproteinase levels and osteoblast apoptosis. Tab significantly reduced the levels of nuclear factor erythroid 2-related factor 2 (Nrf2), haem oxygenase-1 and NAD(P)H quinone dehydrogenase 1. Moreover, it increased the levels of mRNAs encoding runt-related transcription factor 2, bone morphogenetic protein-2 and osterix. These data suggest that Tab ameliorates Dex-induced osteoporosis by regulating the Nrf2 signalling pathway.Improving HIV testing rates and increasing early detection among men who have sex with men (MSM) are critical strategies for enhancing overall health and decreasing HIV transmission. Remote testing and phone delivery of HIV test results may reduce barriers such as geographic isolation or HIV-related stigma. In 2018-19, 50 MSM completed qualitative interviews about their experience receiving a positive HIV test result via phone through their participation in a research study that included remote HIV testing. Interview topics included the acceptability of, and concerns about, phone delivery of HIV results, as well as suggestions for improvement. Interviews were transcribed, coded, and analysed using an inductive thematic approach. Overall, participants reported high acceptability of phone delivery of HIV-positive results. Participants praised the support and information provided by study staff. Benefits identified included increased convenience compared to in-person medical visits, allowing participants to emotionally process their test results privately, as well as receiving the results from supportive and responsive staff members. A few participants indicated drawbacks to phone-based HIV test result delivery, such as logistical concerns about receiving a phone call during the day (e.g., while at work), reduced confidentiality, and the lack of in-person emotional support. Overall, participants described phone delivery of positive HIV-results as acceptable. At-home testing with phone delivery has the potential to increase HIV testing access, especially to geographically isolated or medically underserved patients.Neural populations with strong excitatory recurrent connections can support bistable states in their mean firing rates. Multiple fixed points in a network of such bistable units can be used to model memory retrieval and pattern separation. The stability of fixed points may change on a slower timescale than that of the dynamics due to short-term synaptic depression, leading to transitions between quasi-stable point attractor states in a sequence that depends on the history of stimuli. To better understand these behaviors, we study a minimal model, which characterizes multiple fixed points and transitions between them in response to stimuli with diverse time- and amplitude-dependencies. The interplay between the fast dynamics of firing rate and synaptic responses and the slower timescale of synaptic depression makes the neural activity sensitive to the amplitude and duration of square-pulse stimuli in a nontrivial, history-dependent manner. Weak cross-couplings further deform the basins of attraction for different fixed points into intricate shapes. We find that while short-term synaptic depression can reduce the total number of stable fixed points in a network, it tends to strongly increase the number of fixed points visited upon repetitions of fixed stimuli. Our analysis provides a natural explanation for the system's rich responses to stimuli of different durations and amplitudes while demonstrating the encoding capability of bistable neural populations for dynamical features of incoming stimuli.The interaction between the gut and the liver, often known as the gut-liver axis, play crucial roles in modulating the body's responses to the xenobiotics as well as progression of diseases. Dysfunction of the axis can cause metabolic disorders as well as obesity, diabetes, and fatty liver disease. During the progression of such diseases, inflammatory responses involving the immune system also play an important part. In this study, we developed a three-tissue microphysiological system (MPS) that can accommodate three different cell types in separated compartments connected via fluidic channels in a microfluidic device. Using computational fluid dynamics, geometry of fluidic channels and flow conditions were optimized for seeding and culturing different cell types in the three-tissue MPS. Caco-2 (gut), RAW264.7 (immune), and HepG2 (liver) cells were seeded and cultured in the chip. Stimulation of the gut cells in the MPS with lipopolysaccharide (LPS) resulted in induction of inflammatory response and production of nitric oxide (NO) in all connected chambers. The anti-inflammatory effect of luteolin was demonstrated. Our study demonstrates that the three-tissue MPS can recapitulate the inflammatory responses involving the gut, liver and immune cells.
