An Emerging Technique of Medicated Chewing Gum in Drug Delivery System: A Review

Many advances in research and technology have been made in the oral route of drug delivery system in recent years. Because of increased patient compliance not only in geriatric and paediatric patients, but also in the general population, the oral channel of drug delivery system- medicated chewing gum has received worldwide recognition throughout the year. Chewing gum can be used as a mobile medication delivery device for both local and systemic drug administration via the oral route. Because of its ease and ability to be administered without water, it is an exceptional drug delivery device for self-medication. The production technique, advantages, disadvantages, factors impacting the release of medicament, assessment parameter, difficulty related with chewing gum manufacture, and future trends have all been examined in this review pape

A Review on Using an Alcohol-based Sanitizer as A Prophylactic Measure Against Microorganisms

Because of the COVID 19 pandemic, we now utilise hand sanitizer in our daily lives. Hand hygiene has become a legal requirement. Infection control is becoming a requirement. Hand hygiene is widely regarded as the most practical and effective way of infection prevention. Hand sanitizer is thought to have played a significant role in reducing illness transmission to patients. Because it is more cost-effective and efficient. The efficiency of hand sanitizer is totally determined by how it is used. There are two sorts of hand sanitizers on the market. 1) Hand sanitizer with alcohol 2) Hand sanitizer that isn't alcohol-based. Most effective hand sanitizers contain 70 percent to 95 percent alcohol, which has the potential to denature microbial protein and inactivate viruses. The impact of hand sanitizer on human health care is significant, and this review article will provide you with information on several elements of hand sanitize

Review on Medicated Chocolate Takes A Patient-centered Approach to Drug Delivery

The goal is to create medicinally beneficial chocolate that has no negative side effects. Carob (Ceratonia siliqua), a basic ingredient in many chocolate formulations, was substituted for cocoa since it requires a large amount of sugar in the formulation and includes caffeine, which stimulates the CNS. Carob is high in natural sweeteners, has no fat, caffeine, or oxalates, and is high in antioxidants, which assist to prevent a variety of ailments. Many traditional drug delivery systems are ineffective for paediatric patients because their developmental state and dosing requirements differ from those of other groups of people. Age-appropriate medicines require technological platforms to ensure patient acceptability while maintaining safety, efficacy, accessibility, and affordability. Recent methods and accomplishments in the field of age-appropriate drug delivery for paediatric patients are discussed, including patient-centric formulations, administration devices, and packaging solutions

Serum Amyloid A Receptor Blockade and Incorporation into High-Density Lipoprotein Modulates Its Pro-Inflammatory and Pro-Thrombotic Activities on Vascular Endothelial Cells

The acute phase protein serum amyloid A (SAA), a marker of inflammation, induces expression of pro-inflammatory and pro-thrombotic mediators including ICAM-1, VCAM-1, IL-6, IL-8, MCP-1 and tissue factor (TF) in both monocytes/macrophages and endothelial cells, and induces endothelial dysfunction—a precursor to atherosclerosis. In this study, we determined the effect of pharmacological inhibition of known SAA receptors on pro-inflammatory and pro-thrombotic activities of SAA in human carotid artery endothelial cells (HCtAEC). HCtAEC were pre-treated with inhibitors of formyl peptide receptor-like-1 (FPRL-1), WRW4; receptor for advanced glycation-endproducts (RAGE), (endogenous secretory RAGE; esRAGE) and toll-like receptors-2/4 (TLR2/4) (OxPapC), before stimulation by added SAA. Inhibitor activity was also compared to high-density lipoprotein (HDL), a known inhibitor of SAA-induced effects on endothelial cells. SAA significantly increased gene expression of TF, NFκB and TNF and protein levels of TF and VEGF in HCtAEC. These effects were inhibited to variable extents by WRW4, esRAGE and OxPapC either alone or in combination, suggesting involvement of endothelial cell SAA receptors in pro-atherogenic gene expression. In contrast, HDL consistently showed the greatest inhibitory action, and often abrogated SAA-mediated responses. Increasing HDL levels relative to circulating free SAA may prevent SAA-mediated endothelial dysfunction and ameliorate atherogenesis

β-Catenin Dosage Is a Critical Determinant of Tracheal Basal Cell Fate Determination

The purpose of this study was to determine whether β-catenin regulates basal cell fate determination in the mouse trachea. Analysis of TOPGal transgene reporter activity and Wnt/β-catenin pathway gene expression suggested a role for β-catenin in basal cell proliferation and differentiation after naphthalene-mediated Clara-like and ciliated cell depletion. However, these basal cell activities occurred simultaneously, limiting precise determination of the role(s) played by β-catenin. This issue was overcome by analysis of β-catenin signaling in tracheal air-liquid interface cultures. The cultures could be divided into two phases: basal cell proliferation and basal cell differentiation. A role for β-catenin in basal cell proliferation was indicated by activation of the TOPGal transgene on proliferation days 3 to 5 and by transient expression of Myc (alias c-myc). Another peak of TOPGal transgene activity was detected on differentiation days 2 to 10 and was associated with the expression of Axin 2. These results suggest a role for β-catenin in basal to ciliated and basal to Clara-like cell differentiation. Genetic stabilization of β-catenin in basal cells shortened the period of basal cell proliferation but had a minor effect on this process. Persistent β-catenin signaling regulated basal cell fate by driving the generation of ciliated cells and preventing the production of Clara-like cells

COQ6 mutations in human patients produce nephrotic syndrome with sensorineural deafness

Steroid-resistant nephrotic syndrome (SRNS) is a frequent cause of end-stage renal failure. Identification of single-gene causes of SRNS has generated some insights into its pathogenesis; however, additional genes and disease mechanisms remain obscure, and SRNS continues to be treatment refractory. Here we have identified 6 different mutations in coenzyme Q10 biosynthesis monooxygenase 6 (COQ6) in 13 individuals from 7 families by homozygosity mapping. Each mutation was linked to early-onset SRNS with sensorineural deafness. The deleterious effects of these human COQ6 mutations were validated by their lack of complementation in coq6-deficient yeast. Furthermore, knockdown of Coq6 in podocyte cell lines and coq6 in zebrafish embryos caused apoptosis that was partially reversed by coenzyme Q10 treatment. In rats, COQ6 was located within cell processes and the Golgi apparatus of renal glomerular podocytes and in stria vascularis cells of the inner ear, consistent with an oto-renal disease phenotype. These data suggest that coenzyme Q10–related forms of SRNS and hearing loss can be molecularly identified and potentially treated

Hydrogen Intensity and Real-Time Analysis Experiment: 256-element array status and overview

International audienceThe Hydrogen Intensity and Real-time Analysis Experiment (HIRAX) is a radio interferometer array currently in development, with an initial 256-element array to be deployed at the South African Radio Astronomy Observatory Square Kilometer Array site in South Africa. Each of the 6 m, f  /  0.23 dishes will be instrumented with dual-polarization feeds operating over a frequency range of 400 to 800 MHz. Through intensity mapping of the 21 cm emission line of neutral hydrogen, HIRAX will provide a cosmological survey of the distribution of large-scale structure over the redshift range of 0.775  <  z  <  2.55 over ∼15,000 square degrees of the southern sky. The statistical power of such a survey is sufficient to produce ∼7  %   constraints on the dark energy equation of state parameter when combined with measurements from the Planck satellite. Additionally, HIRAX will provide a highly competitive platform for radio transient and HI absorber science while enabling a multitude of cross-correlation studies. We describe the science goals of the experiment, overview of the design and status of the subcomponents of the telescope system, and describe the expected performance of the initial 256-element array as well as the planned future expansion to the final, 1024-element array
