Inhalation delivery of host defence peptides (HDP) using nano-formulation strategies: A pragmatic approach for therapy of pulmonary ailments.

Inhalation delivery of host defence peptides (HDP) using nano-formulation strategies: A pragmatic approach for therapy of pulmonary ailments. Curr Protein Pept Sci. 2019 Dec 30;: Authors: Adlakha S, Sharma A, Vaghasiya K, Ray E, Verma RK Abstract Host defense peptides (HDP) are small cationic molecules released by the immune systems of the body, having multidimensional properties including anti-inflammatory, anticancer, antimicrobial and immune-modulatory activity. These molecules gained importance due to their broad-spectrum pharmacological activities, and hence being actively investigated. Presently, respiratory infections represent a major global health problem, and HDP has an enormous potential to be used as an alternative therapeutics against respiratory infections and related inflammatory ailments. Because of their short half-life, protease sensitivity, poor pharmacokinetics, and first-pass metabolism, it is challenging to deliver HDP as such inside the physiological system in a controlled way by conventional delivery systems. Many HDPs are efficacious only at practically high molar-concentrations, which is not convincing for the development of drug regimen due to their intrinsic detrimental effects. To avail the efficacy of HDP in pulmonary diseases, it is essential to deliver an appropriate payload into the targeted site of lungs. Inhalable HDP can be a potentially suitable alternative for various lung disorders including tuberculosis, Cystic fib...

In this study, two novel benzimidazolium salts consisting propane sulfonate order were integrated in high yields as N-heterocyclic carbene (NHC) precursors.The silver-NHC buildings were set up by responding 1-(2,2-dimethoxyethyl)- 3-(propyl-3-sulfonate)benzimidazolium and 1-(2,2-diethoxyethyl)- 3-(propyl-3-sulfonate)benzimidazolium with silver oxide on average state. Gold-NHC edifices were acquired by means of transmetallation of their silver precursors with [AuCl{S(CH3)2}]. The structures of all mixes were completely portrayed by spectroscopic techniques (1H-NMR, 13C{1H} NMR , IR and elemental and further analyzed by DFT/...

Narayana MurthyAbstractIntroductionGlobally, cervical cancer is the 4th most common cancer and is one of the leading cancers causing death in India. Cervical cancer is one of those cancers which can be easily prevented by screening women who are aged above 30 years and by vaccinating young girls against HPV. Lack of awareness about cervical cancer makes early detection and timely screening difficult. Awareness about cervical cancer among people will help us to decide on an appropria...

ConclusionsOur findings support measurement invariance of the EORTC QLQ-C30 in a large sample of patients with hematological malignancies. The results showed that the number of non-invariant items was negligible, suggesting that this questionnaire is a valid and robust measurement tool in patients with hematological malignancies, also for comparisons across groups and time.

To date, many of them are still in urgent need of characterisation, and role of miR-595 in hepatocellular carcinoma (HCC) remains unknown. To better understand the mechanism of miR-595 in HCC development, a series of experiments were carried out to explore the effects of miR-595 on malignant behaviour in HCC. First, we found that miR-595 was downregulated in HCC tissues and cells and tightly associated w...

ConclusionFindings from this study suggest that the SS-PU-SS-PEG micelles could achieve well-controlled triggered drug release in a reduction environment and could therefore improve the antitumor efficacy of osteosarcoma therapies.Translation potential of this articleIn this study we developed PEG-sheddable reduction-sensitive polyurethane micelles (SS-PU-SS-PEG), which were able to achieve well-controlled triggered release of anti-tumor drug Doxorubicin (DOX) in an intracellular reduction environment. DOX-loaded SS-PU-SS-PEG micelles markedly improved the antitumor efficacy in a Saos-2 cells-bearing xenograft tumor model....

In this study they also showed PTX3 localized in NETs formed after neutrophil activation (5). Proteomics analysis revealed that PTX3 forms complexes with two anti-microbial proteins [azurocidin (AZU1) and myeloperoxidase (MPO)] associated to NETs (30). More recently, PTX3 localization in NETs has been confirmed, and the colocalization with AZU1 and MPO has been defined more accurately (31). Further investigation will be needed to understand the involvement of PTX3 interaction with AZU1 and MPO in their antibacterial role during NET formation. Regulation of Complement Activation PTX3 interaction with microorganisms is not...

Authors: Mur LA, Huws SA, Cameron SJ, Lewis PD, Lewis KE Abstract The lung microbiome has been shown to reflect a range of pulmonary diseases-for example: asthma, chronic obstructive pulmonary disease (COPD) and cystic fibrosis. Studies have now begun to show microbiological changes in the lung that correlate with lung cancer (LC) which could provide new insights into lung carcinogenesis and new biomarkers for disease screening. Clinical studies have suggested that infections with tuberculosis or pneumonia increased the risk of LC possibly through inflammatory or immunological changes. These have now been supersede...
