For example, those with transportation needs were 84% more likely to have an alcohol/drug use disorder diagnosis (95% CI 1.59, 2.13) and 41% more likely to smoke (95% CI 1.25, 1.58). Specific social needs may influence clinical issues in distinct ways. These findings suggest that health systems need to develop strategies that address unmet social need in order to optimize health outcomes, particularly in communities with a dual burden of poverty and chronic disease.We aimed to identify differences in prescription opioid-related behaviors between adults with and without disabilities in the U.S. We analyzed data from the 2015-2017 National Survey on Drug Use and Health (128,740 individuals; weighted N of 244,831,740) to examine disability-based differences in (1) reasons and sources of last prescription opioid misuse and, in multivariate models overall and stratified by disability, the likelihood of (2) prescription opioid use, and if used, (3) misuse and prescription opioid use disorder (OUD), overall and stratified by disability. Adults with disabilities were 11% more likely than adults without disabilities to report any past-year prescription opioid use, adjusted for sociodemographic, health, and behavioral health characteristics. However, among adults with any prescription opioid use, which is more common among people with disabilities, likelihood of prescription OUD did not vary by disability status. Pain relief as the reason for last misuse was associated with 18% increased likelihood of prescription OUD, if any use. To reduce risk of opioid misuse among people with disabilities, accessible and inclusive chronic pain management services are essential. Further, the substance use treatment field should provide accessible and inclusive services, and be aware of the need for pain management by many people with disabilities, which may include the use of prescription opioids. These findings highlight essential opportunities for public health and policies to improve access, accommodations, and quality of health and behavioral health care for people with disabilities, and to encourage a holistic perspective of people with disabilities and their needs.COVID-19 pathology involves dysregulation of diverse molecular, cellular, and physiological processes. To expedite integrated and collaborative COVID-19 research, we completed multi-omics analysis of hospitalized COVID-19 patients, including matched analysis of the whole-blood transcriptome, plasma proteomics with two complementary platforms, cytokine profiling, plasma and red blood cell metabolomics, deep immune cell phenotyping by mass cytometry, and clinical data annotation. We refer to this multidimensional dataset as the COVIDome. We then created the COVIDome Explorer, an online researcher portal where the data can be analyzed and visualized in real time. We illustrate herein the use of the COVIDome dataset through a multi-omics analysis of biosignatures associated with C-reactive protein (CRP), an established marker of poor prognosis in COVID-19, revealing associations between CRP levels and damage-associated molecular patterns, depletion of protective serpins, and mitochondrial metabolism dysregulation. We expect that the COVIDome Explorer will rapidly accelerate data sharing, hypothesis testing, and discoveries worldwide.The adult mammal lacks the ability to regenerate neurons lost to retinal damage or disease in a meaningful capacity. However, previous studies from this laboratory have demonstrated that PNU-282987, an α7 nicotinic acetylcholine receptor agonist, elicits a robust neurogenic response in the adult murine retina. With eye drop application of PNU-282987, Müller glia cells re-enter the cell cycle and produce progenitor-like cells that can differentiate into various types of retinal neurons. In this study, we analyzed the regenerative capability of PNU-282987 in two retinal disease models and identified the source of newly regenerated neurons. Wild-type mice and mice with a transgenic Müller-glia lineage tracer were manipulated to mimic loss of retinal cells associated with glaucoma or photoreceptor degeneration. Following treatment with PNU-282987, the regenerative response of retinal neurons was quantified and characterized. After onset of photoreceptor degeneration, PNU-282987 was able to successfully regenerate both rod and cone photoreceptors. Quantification of this response demonstrated significant regeneration, restoring photoreceptors to near wild-type density. In mice that had glaucoma-like conditions induced, PNU-282987 treatment led to a significant increase in retinal ganglion cells. Retrograde labeling of optic nerve axon fibers demonstrated that newly regenerated axons projected into the optic nerve. Lineage tracing analysis demonstrated that these new neurons were derived from Müller glia. These results demonstrate that PNU-282987 can induce retinal regeneration in adult mice following onset of retinal damage. The ability of PNU-282987 to regenerate retinal neurons in a robust manner offers a new direction for developing novel and potentially transformative treatments to combat neurodegenerative disease.There is considerable interest in developing antibodies as modulators of signaling pathways. One of the most important signaling pathways in higher eukaryotes is the phosphoinositide 3-kinase (PI3K) pathway, which plays fundamental roles in growth, metabolism, and immunity. The class IB PI3K, PI3Kγ, is a heterodimeric complex composed of a catalytic p110γ subunit bound to a p101 or p84 regulatory subunit. PI3Kγ is a critical component in multiple immune signaling processes and is dependent on activation by Ras and G protein-coupled receptors (GPCRs) to mediate its cellular roles. Here we describe the rapid and efficient characterization of multiple PI3Kγ binding single-chain camelid nanobodies using hydrogen-deuterium exchange (HDX) mass spectrometry (MS) for structural and biochemical studies. We identify nanobodies that stimulated lipid kinase activity, block Ras activation, and specifically inhibited p101-mediated GPCR activation. Overall, our work reveals insight into PI3Kγ regulation and identifies sites that may be exploited for therapeutic development.Until now, the Draize test on rabbits has been the only test performed to anticipate ocular toxicity of pharmaceutical compounds, mainly irritation. The OECD is urging the scientific community to develop and validate alternative methods to reduce the need for animal testing. Since the models and tests used cannot reflect the entire biologic response, it is necessary to combine them into integrated approaches to testing and assessment (IATA) to obtain robust data. IATAs, along with adverse outcome pathways (AOP) that encompass molecular cascades and key events, require the best combinations of tests. This commentary manuscript describes these OECD tools and proposes original approaches for ocular surface AOP and an IATA for toxicity-induced dry eye (TIDE).A parasitic dinoflagellate of the genus Hematodinium was found off the Pacific coast of Kamchatka in three species of crabs red king crab Paralithodes camtschaticus, tanner crab Chionoecetes bairdi, and spiny king crab Paralithodes brevipes. This is the first detection of Hematodinium in spiny king crab. The results of the genetic analysis showed that the pathogen found in P. brevipes, P. camtschaticus, and C bairdi from the Avacha and Kronotsky bays off the Pacific coast of Kamchatka was the same or very close to the Hematodinium sp., which infects many species of crustaceans in the Northern Hemisphere. The prevalence of infection was 0.2% for tanner crabs and 2.7% for red king crabs. Due to a limited sample size, we were unable to calculate the prevalence for spiny king crabs and female red king crabs. Both the macroscopic and microscopic signs of the pathology were similar in all diseased crabs. The differences in the micromorphology of the Hematodinium cells we found in the three crab species, including the presence or absence of trichocysts, the shape of the plasmodia, and the structure of pore complexes, are most likely related to the life cycle and the physiology of the parasite. The results of the genetic analysis showed that the pathogen found in P. brevipes, P. camtschaticus, and C. bairdi from the Avacha and Kronotsky bays of the Pacific coast of Kamchatka was the same or very close to the Hematodinium sp., which infects many species of crustaceans in the Northern Hemisphere.Gongolaria baccata (S.G. Gmelin) is marine brown seaweed mainly found on the coasts of the Baltic Sea south to the Mediterranean Sea, Canary Islands, Mauritania and Western Sahara. Herein, we report the cell viability and protective effects attributed to molecular mechanisms underlying antioxidant response to survive oxidative stress injuries. Caco-2 cells were submitted to oxidative stress by treatment with tert-butylhydroperoxide (tert-BOOH). The extract prevented cell damage and enhanced activity of antioxidant defenses (NQO1 and GST activities and GSH levels) reduced by treatment with tert-BOOH. The increases of MDA levels, the amount of intracellular ROS and caspase 3/7 activity induced by tert-BOOH were prevented when cells were treated with the G. baccata extract. Moreover, G. baccata extract caused up-regulation of GSTM2, Nrf2, and AKT1 gene expressions, as well as G. baccata extract reduced significantly Bax, BNIP3, APAF1, ERK1, JNK1, MAPK1, P38, P53, NFκB1, TNFα, IL-6, IL-1β and HO-1 gene expressions related to apoptosis, proinflammation and oxidative stress induced by tert-BOOH. These results suggest that G.baccata extract protected the cells against oxidative damage and inflammation; protective effects that could be linked to their bioactive constituents. Hence, this brown seaweed G.baccata extract could be used for the development of functional foods and/or nutraceuticals.Diabetic cardiomyopathy (DCM) significantly increased the morbidity of heart failure in diabetic patients. Long-time oxidative stress is an indisputable contributor for DCM development. Apocynin (APO) has been suggested to be a potential drug against oxidative stress. The study aims to find out the effects of APO on DCM and the related mechanisms. Mice were randomly divided into four groups control (CON), APO, DCM and DCM + APO. Echocardiography analyses, histological analyses, Western blot and RT-PCR were used to explore the roles and mechanisms of APO in DCM. Isolated neonatal rat cardiomyocytes (NRCMs) and cardiac fibroblasts (CFs) were used for further confirming the APO treatment effects in vitro. Deteriorated cardiac function, enlarged cardiomyocytes, excess cardiac fibrosis and significant cardiac oxidative stress were observed in DCM group. selleck screening library However, APO treatment successfully improved cardiac function, decreased cardiac hypertrophy and fibrosis, and depressed oxidative stress. Mechanistically, APO treatment markedly suppressed apoptosis signal regulating kinase 1(ASK1)-p38/c-jun N-terminal kinase (JNK) signaling and reduced apoptosis. It also inhibited NRCM apoptosis and CF activation via depressing ASK1-p38/JNK signaling in vitro. Moreover, adenovirus-mediated ASK1 overexpression completely removed the protection of APO in vitro. In conclusion, APO treatment could effectively attenuate DCM-associated injuries in vivo and protect against high glucose-induced NRCM and CF injuries in vitro via suppressing ASK1-p38/JNK signaling. APO might be a potential ASK1 inhibitor for treating DCM.
