Active Symptom-Based Surveillance of Adverse Events Following Immunization among Individuals Vaccinated with ChAdOx1 nCoV-19 Coronavirus Vaccine in a Tertiary Hospital of Kerala
CONCLUSION: All the adverse reactions were of a minor type and non-serious. Side effects were less common in older adults (>60 years). Reactions to the second dose were lesser in intensity and frequency. Younger age, history of allergy, and comorbidities, particularly asthma were found to be major predictors for the development of adverse events and require more watchful vaccine administration.PMID:35135453 | DOI:10.2174/1574886317666220207120649

Nanoparticle drug delivery characterization for fluticasone propionate and in vitro testing.
Abstract Glucocorticoids (GCs), such as Fluticasone Propionate (FP), are used for the treatment of inflammation and alleviation of nasal symptoms, allergy, and as anti-pruritic. However, both short and long-term therapeutic use of GCs can lead to muscle weakness and atrophy. In the present study, we evaluated the feasibility of the nano-delivery of FP with polylactic glycolic acid (PLGA) and tested in vitro function. FP-loaded PLGA nanoparticles (NPs) were prepared via nanoprecipitation and morphological characteristics of were studied via scanning electron microscopy. FP-loaded nanoparticles demonstrated an encap...

Systems Biology Analysis of the Effect and Mechanism of Qi-Jing-Sheng-Bai Granule on Leucopenia in Mice
Conclusion In summary, our data reveal the therapeutic mechanism of QJSB by integrative application of transcriptomics-based network pharmacology and metabolomics technologies. QJSB exerts protective effect against leucopenia in mice through participating in multi-pathways, mainly including accelerating cell proliferation and differentiation, regulating metabolism response pathways and modulating immunologic function. Ethics Statement All animal studies were performed according to the institutional ethical guidelines of animal care and were approved by the Committee on the Ethics of Animal Experiments of the Second Mili...

Oligonucleotides —A Novel Promising Therapeutic Option for IBD
Conclusions In this review, we focused on recent and past approaches to test the therapeutic efficacy of oligonucleotide based therapies in IBD. The combining mechanistic mode of oligonucleotide based therapeutics is a targeted action on specific pro-inflammatory molecules, which are over activated in IBD patients and contribute significantly to disease pathogenesis. The proposed high selectivity of the agents is derived from its mode of action, that aims to specifically block certain inflammatory molecular patterns, without a general systemic effect on other molecular targets. It would be important for each oligonucleot...

Geniposide Alleviates Glucocorticoid-Induced Inhibition of Osteogenic Differentiation in MC3T3-E1 Cells by ERK Pathway
Conclusion In summary, we demonstrated that geniposide alleviated GC-induced osteogenic suppression in MC3T3-E1 cells. The effects of geniposide were at least partially associated with activating ERK signaling pathway via GLP-1 receptor. Geniposide might be a potential therapeutic agent for protection against GC-induced osteoporosis. Author Contributions BX, DX, CZ, and LW participated in research design. BX, JW, YL, XW, and ZZ conducted the experiments. BX, DX, and LW contributed new reagents or analytic tools and wrote or contributed to the writing of the manuscript. BX, JW, CZ, and DX performed the data analysis. Fu...

Focused Ultrasound Improves NK-92MI Cells Infiltration Into Tumors
Conclusion In conclusion, we demonstrated that the combination of FUS and microbubbles could increase the NK-92MI cells’ infiltration into tumors in this study. The combination of FUS and NK-92MI had a much better therapeutic effect when compared with the PBS group, but no superior therapeutic effect when compared with the NK-92MI group. In total, FUS and microbubbles can improve NK cells’ infiltration into tumors, but future work is still needed to improve NK-92MI cells’ delivery efficiency for solid tumor treatment. Ethics Statement This study was carried out in accordance with the recommendations...

The Study of Dried Ginger and Linggan Wuwei Jiangxin Decoction Treatment of Cold Asthma Rats Using GC –MS Based Metabolomics
Conclusion In this study, serum and urine metabolites identified by GC–MS and general pharmacodynamic evaluation (morphological observation, histopathology, inflammatory factors, and visceral indices) were used to compare the effects of GJ and LGWWJX decoctions on cold asthma. Significant metabolic abnormalities were observed for 37 metabolites (15 in serum, 22 in urine) in rats with cold asthma. These altered metabolites might be potential biomarkers or therapeutic targets during development of cold asthma. Furthermore, pathway analysis demonstrated that pathways associated with energy metabolism and oxidative str...

Qingpeng Ointment Ameliorates Inflammatory Responses and Dysregulation of Itch-Related Molecules for Its Antipruritic Effects in Experimental Allergic Contact Dermatitis
Conclusion Via a HPLC system and a BATMAN-TCM platform, for the first time we performed detailed HPLC fingerprint analysis and network pharmacology studies of QP ointment. By in-depth animal and molecular analysis, we identified a number of chronic dermatitis-associated Th1/2 cytokines, itch mediators, and cellular signaling pathways in the skin, DRG and serum for QP to treat the inflammation and chronic itch associated with ACD. Our data clearly suggested, upon stimulation, cytokines and itch-related mediators are released from the skin and neuronal tissues, and QP could effectively work on both the skin and sensory neur...

Histamine and Delirium: Current Opinion
This study indicated that switch from H2 blockers to PPIs reduced delirium and, thus, providing an appropriate strategy to combat drug-induced delirium using antiulcer drugs (Fujii et al., 2012). The ventrolateral preoptic nucleus is a sleep-promoting nucleus located in the basal forebrain. A commonly used intravenous anesthetic, propofol, had been reported to induce sleep and augment the firing rate of neurons in ventrolateral GABAergic preoptic nucleus, but the underlining mechanism is yet to be clearly determined. Interestingly, the propofol-induced inhibition of inhibitory postsynaptic currents on noradrenalin-inhibite...
