Cordyceps militaris has been widely studied for its various pharmacological activities such as antitumor, anti-inflammation, and immune regulation. The binding of an allergen to IgE-sensitized mast cells in nasal mucosa triggers allergic rhinitis. We found that oral administration of 300 mg/kg of the ethanol extract prepared from silkworm pupa-cultivated Cordyceps militaris fruiting bodies significantly alleviated the symptoms of ovalbumin-induced allergic rhinitis in mice, including sneeze/scratch, mast cell activation, eosinophil infiltration, and Syk activation. The treatment of ethanol extract significantly suppressed the release of β-hexosaminidase (a degranulation marker) and mRNA expression levels of various cytokines, including IL-3, IL-10, and IL-13 in activated RBL2H3 cells. The ethanol extract and β-sitostenone, which was purified from the extract, could respectively reduce the Ca2+ ion mobilization in activated RBL-2H3 cells. Furthermore, results collected from western immunoblotting demonstrated that ethanol extract significantly retarded Ca2+ ion mobilization-initiated signaling cascade, which provoked the expression of various allergic cytokines. Also, the extract incubation interfered with P38 as well as NF-kB activation and Nrf-2 translocation. Our study suggested that ethanol extract possessed some natural constituents which could inhibit immediate degranulation and de novo synthesis of allergic cytokines via inhibition of Ca2+ ion mobilization in mast cells in the nasal mucosa of allergic rhinitis mice.
Degenerative diseases of the musculoskeletal system significantly reduce the quality of human life. Hip resurfacing is used to treat degenerative diseases in the later stages. After surgery, there is a risk of endoprosthesis loosening and low-energy fracture during daily physical activity. Computer modeling is a promising way to predict the optimal low-energy loads that do not lead to bone destruction. This paper aims to study numerically the mechanical behavior of the proximal femur, amenable to degenerative changes and subjected to hip resurfacing under low-energy impact equivalent to physiological loads.
A numerical model of the mechanical behavior of the femur after hip resurfacing arthroplasty under low-energy impacts equivalent to physiological loads is presented. The model is based on the movable cellular automaton method (discrete elements), where the mechanical behavior of bone tissue is described using the Biot poroelasticity accounting for the presence and transfer of interstitial biological flof the structure of the patient's bone tissues.
Now-a-days in medical science, the transport study of biological fluids through non-uniform vessels are going to increase due to their close relation to the reality. Semaglutide datasheet Motivated through such type of complex transportation, the current study is presented of cilia hydro-dynamics of an aqueous electrolytic viscous fluid through a non-uniform channel under an applied axial electric field. Mathematical Formulations Because of the complexity shape and nature of flow channel, we have used curvilinear coordinates in the derivation of continuity and momentum equationsin a fixed frame of reference. A linear transformation is used to renovate the flow system of equations from fixed (laboratory) to moving (wave) frame. For further simplification, the dimensionless variables are introduced to make the flow system of equations into the dimensionless form and at last convert these equations in term of stream function by using the mathematical terminologies of streamlines. The whole analysis is performed under (low Reynolds f the channel but also the length of bolus increased. Results of straight channel are gained for larger value of the dimensionless radius of curvature parameter as well as cilia length.Due to several limitations of the only available BCG vaccine, to generate adequate protective immune responses, it is important to develop potent and cost-effective vaccines against tuberculosis (TB). In this study, we have used an immune-informatics approach to identify potential peptide based vaccine targets against TB. The proteome of Mycobacterium tuberculosis (Mtb), the causative agent of TB, was analyzed for secretory or surface localized antigenic proteins as potential vaccine candidates. The T- and B-cell epitopes as well as MHC molecule binding efficiency were identified and mapped in the modelled structures of the selected proteins. Based on antigenicity score and molecular dynamic simulation (MD) studies two peptides namely Pep-9 and Pep-15 were analyzed, modelled and docked with MHC-I and MHC-II structures. Both peptides exhibited no cytotoxicity and were able to induce proinflammatory cytokine secretion in stimulated macrophages. The molecular docking, MD and in-vitro studies of the predicted B and T-cell epitopes of Pep-9 and Pep-15 peptides with the modelled MHC structures exhibited strong binding affinity and antigenic properties, suggesting that the complex is stable, and that these peptides can be considered as a potential candidates for the development of vaccine against TB.
The importance of environmental risk factors in the onset of multiple sclerosis (MS) has been studied extensively. Similarly, a growing number of studies address the importance of environmental factors, including seasonality, for ongoing activity of established disease. Specifically, past research demonstrates higher rates of relapse activity in summer months among individuals with MS. Our study adds to the existing literature on seasonality of disease relapse by analysing a large population-based and virtually complete cohort of patient with relapsing and remitting MS (RRMS) in an area of temperate climate.
The Danish Multiple Sclerosis Registry includes follow-up for all patients receiving disease modifying treatment from 1996-2020, with near-complete registration of all relapses and their dates. We compared the observed and expected numbers of relapses for each calendar month and calculated month-specific annualized relapse rates (ARR) using Poisson regression. In addition, we analysed seasonal variation in disability as measured by the Expanded Disability Status Scale (EDSS).
