The study was designed to investigate the antithyroid activity of the crude methanolic (70%) extract of aerial parts of Abutilon indicum in male albino rats. The extract was prepared and analyzed for the presence of phytochemical constituents through preliminary chemical analysis, antioxidant assay and GC-MS. The in vivo antithyroid activities in thyroxine-induced hyperthyroidism were studied. Phytochemical analysis showed the presence of alkaloids, flavonoids and phenols, also verified by the data obtained from GC-MS. Thyroxine increased the levels of triiodothyronine (4.9 ± 0.1 ng/mL) and total thyroxine (9.4 ± 0.2 μg/dL); while, A. indicum at the doses of 300 and 500 mg/kg, showed significant decrease in the elevated levels of triiodothyronine (3.0 ± 0.1 and 2.6 ± 0.2 ng/mL) and thyroxine (7.7 ± 0.2 and 7.1 ± 0.2 μg/dL), respectively. Histopathological studies showed the restoration of filled follicular colloids in extract-treated animals. The results show that A. indicum exhibits dose-dependent antithyroid effects.

Bombyx batryticatus, the dried larvae of Bombyx mori infected by Beauveria bassiana, is a renowned traditional medicine. Previous report shows that B. batryticatus improved behavioral impairments, protected dopaminergic neurons, and maintained dopamine levels by inhibiting oxidative signaling in murine Parkinson’s disease model. In this study, the inhibitory effects of B. batryticatus on 1-methyl 4-phenyl 1,2,3,6-tetrahydropyridine (MPTP)-induced Parkinson’s disease in mice was investigated and explored the corresponding molecular mechanisms, while focusing on NF-κB signaling. Consequently, it was found that B. batryticatus inhibited glial and microglial activation and the levels of neuroinflammatory mediators, such as Cox-2, iNOS, and NF-kB, in the substantia nigra pars compacta. Moreover, pre-inhibition of NF-κB by BAY 11-7082, a κB kinase inhibitor, could neutralize the inhibitory effects of B. batryticatus against the activation of glia and microglia formerly induced by MPTP. It can be considered that B. batryticatus holds implications in providing anti-inflammatory neuroprotection by regulating NF-κB signaling.

The aim of this study was to determine the antibacterial activity of Cathormion umbellatum extracts against seven antibiotic-resistant bacteria. The pods, leaves and branches of C. umbellatum were extracted with ethanol and methanol. The disc diffusion assay was used to screen the antibacterial activity and broth microdilution and colorimetric assay were used to measure the minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) values. The result indicated that the highest inhibition zone (11 mm) was presented in ethanolic pods extract against multidrug resistance Klebsiella pneumoniae. The lowest MIC value of 0.05 mg/mL was obtained from branch extracted with ethanol against colistin resistant Pseudomonas aeruginosa. The lowest MBC values of 1.56 mg/mL were obtained when using C. umbellatum leaves extracted with methanol against all test antibiotic-resistant bacteria. This is the first report presented C. umbellatum extracts have the potential to eliminate antibiotic-resistant bacteria in patients. These findings show the antibacterial effect of C. umbellatum.

Vascular endothelial dysfunction is characterized by apoptosis of endothelial cells, an imbalance between vasoconstrictory and vasodilatory substances, the imbalance between ROS and antioxidants, vascular remodeling, loss of vascular integrity which leads to an increased risk of cardiovascular complications. To date, no therapeutic intervention is available as a promising agent. This may be due to a poor understanding of the underlying mechanism involved in vascular endothelial dysfunction in the pathogenesis. Animal models sharing identical features as that of humans are paramount to understand fundamental physiology, mechanism and to explore new targets for developing therapeutic agents. Thus, it becomes mandatory to re-explore the available animal models for a better understanding of molecular pathways involving vascular endothelial dysfunction. The purpose of this paper is to review different models for vascular endothelial dysfunction to the outlook for developing new drugs to treat vascular endothelial dysfunction.

This study was designed to evaluate the anti-cancer effects of bufalin against the human gastric cancer cells and unveil the underlying mechanism. The results showed that bufalin inhibited the proliferation and colony formation of the MGC-803 gastric cancer cells and exhibited an IC50 of 10 μM. These antiproliferative effects were found to be due to the induction of G2/M cell cycle arrest. The G2/M cell cycle arrest was also concomitant with inhibition of cdc2, cdc25 and cyclin B1. Furthermore, bufalin suppressed the epithelial-to-mesenchymal transition, migration, and invasion of the MGC-803 gastric cancer cells. The Western blot analysis revealed that bufalin exerted its effects via deactivation of EK/ERK signaling pathway. Taken together, these results suggest the potential of bufalin as the lead molecule for the development of chemotherapy for gastric cancer.

This meta-analysis is to systematically evaluate the efficacy and safety of beta-blockers in the treatment of sepsis. A total of 17 articles that met the inclusion criteria were included, and 10,385 cases were obtained. The meta-analysis results showed that patients with sepsis with beta-blocker usage had a significantly lower 28-day mortality. The heart rate decreased over time in patients with sepsis using beta-blocker. Moreover, central venous blood oxygen saturation increased after 24, 48, 72 hours of treatment; lactic acid and cardiac troponin I decreased after 48, 72 hours of treatment; and tumor necrosis factor-α, interleukin-1β levels decreased significantly after 12, 24, 48, 72 hours of treatment (p<0.05). In conclusion, beta-blockers reduce 28-day mortality and heart rate.

The present study was undertaken to decipher the role of HOXC10 gene in regulating the growth and metastasis of prostate cancer. The results revealed significant (p<0.05) up-regulation of HOXC10 gene in human prostate cancer tissues and cell lines. The silencing of HOXC10 transcript level significantly (p<0.05) inhibited the growth and colony formation of DU145 and 22Rv1 prostate cancer cells. The DAPI staining revealed that inhibition of DU145 and 22Rv1 prostate cancer cell viability was due to the induction of apoptosis. The transwell assay showed that HOXC10 significantly (p<0.05) inhibits the invasion of prostate cancer cells. The Western blotting revealed that HOXC10 gene exerts its effects via modulation of Ras/Raf/MEK/ERK signaling cascade. Collectively, the results point towards the therapeutic potential of HOXC10 in the treatment of prostate cancer.
