Chronic total occlusion (CTO) is defined as coronary artery obstruction with no luminal continuity. Comparative outcomes of PCI in patients with in-stent CTO (IS-CTO) versus de-novo CTO are unclear.

An extensive literature search was done for outcomes of PCI in patients undergoing IS-CTO and de-novo CTO. The primary endpoint was major adverse cardiac events (MACE) and secondary endpoints were cardiovascular mortality, MI, and procedural success. Odds ratio (OR) with a 95% confidence interval (CI) was calculated using RevMan 5.3.

Five studies consisting of 3,681 patients (IS-CTO = 464, de-novo CTO = 3,217) were included. PCI in IS-CTO was associated with a significantly higher odds of MACE (OR 2.21, 95% CI 1.32-3.68, p = 0.002) and MI (OR 4.31, 95% CI 1.94-9.58, p = 0.0003) compared to patients with de-novo CTO. Mortality outcome (OR 1.49, 95% CI 0.93-2.39, p = 0.10) between the two groups was similar. Overall odds of procedural-success were similar among the groups (OR 1.11, 95% CI 0.84-1.46, p = 0.47).

PCI for in-stent CTO might be associated with higher odds of MACE and MI compared to PCI for de-novo CTO. However, cardiovascular mortality or failure of procedure are similar.

Our aim was to investigate the possible neuroprotective properties of papaverine in sepsis-induced critical illness neuropathy (SCIN) through the evaluation of various inflammatory biochemical markers, including interleukin 6 (IL-6), C-reactive protein (CRP), and tumor necrosis factor-alpha (TNF-α), and oxidative stress biomarkers, such as malondialdehyde (MDA) and lactic acid. Additionally, evaluation of the HMGB1/RAGE interactions in SCIN was another target of this research.

To create a sepsis model, a procedure involving intraperitoneal injection of feces was performed on 48 rats. The rats were divided into four equal groups sham operated, controls and those receiving 20 and 40 mg/kg/day papaverine. After five-day treatments, compound muscle action potential (CMAPs) with electroneuromyography (ENMG) was recorded in all rats. Following ENMG evaluations, the plasma levels of sRAGE, HMGB1, TNF-α, IL-6, CRP, MDA and lactic acid were measured.

TNF-α, CRP, IL-6, HMGB1, MDA, and lactic acid levels were significantly elevated in the SCIN group, and sRAGE levels were significantly decreased. In recipients of papaverine (20 and 40 mg/kg) treatment, these biochemical findings were improved. Furthermore, electrophysiological findings also showed significant improvement in both 20 and 40 mg/kg papaverine treated groups.

Papaverine demonstrates neuroprotective effects in a rat model of SCIN. Considering its anti-inflammatory and antioxidant properties, papaverine's neuroprotective effects possibly stem from the suppression of the RAGE-HMGB1 axis.

Zika virus (ZIKV) is transmitted to humans throughout bites of

mosquitoes. ZIKV infection may be asymptomatic in most cases, but it may cause fever, headache, muscle pain, and rash. Guillain-Barré syndrome also may be associated with the infection. Furthermore, the Pan American Health Organization informed 3,715 cases of the congenital ZIKV syndrome (CZS) in the Americas from 2015 - 2017, which may include microcephaly and other craniofacial deformities.

This review identifies patent documents on repositioning for ZIKV infection treatment of already approved drugs or phases II/III investigated drugs for other diseases. Thirty-six patents were found reporting compounds with anti-ZIKV activity with application dates ranging from 2015 to 2019.

The main drugs claimed in patents were ribavirin, sofosbuvir, and alpha interferons. Preventing CZS is one of the most significant challenges in ZIKV infection. Therefore, repositioning sofosbuvir and niclosamide, that pose no danger for pregnant women, is a particular issue to be considered for clinical tests involving ZIKV disease. Given the substantial costs and developing time of new a drug, repositioning of old drugs is becoming an attractive alternative for diseases with neglected treatments.

However, radiation-induced pneumonitis and fibrosis are the treatment-limiting toxicities among patients who have undergone radiotherapy. The epithelial cells via epithelial to mesenchymal transition [EMT] acquires mesenchymal phenotype, which ultimately leads to fibrosis. Many investigations are focussed on understanding the signalling pathways mediating in EMT, however, the role of histone methylation is less understood in radiation-induced lung EMT. A1874 cost In the present study, we analysed the effect of vanillin, an antioxidant, on histone methylation during radiation-induced EMT. The thoracic region of Wistar rats was irradiated with a fractionated dose of X-ray (3 Gy/day) for two weeks (total of 30 Gy). The irradiated animals were sacrificed at the 8th and 16th weeks and tissues were used for analyses. Our data showed that radiation decreased the level of antioxidant enzymes such as SOD, catalase and reduced glutathione that would ultimately enhance oxidative stress in the tissues. Histopathological analysis revealed that radiation increased the infiltration of inflammatory cells to the tissue injury site. Total global histone methylation was increased upon irradiation, which was effectively prevented by vanillin administration. Vanillin enhanced E-cadherin expression and decreased the mesenchymal markers N-cadherin and vimentin in the irradiated lung tissue. The ChIP-qPCR analysis suggested that snail expression in the nucleus might involve in the enrichment of suppressive marker H3K9me3 on the E-cadherin promoter. Finally, we suggested that vanillin administration decreased radiation-induced oxidative stress and EMT expression. Additionally, irradiation increased the H3K9 methylation status with nuclear translocation of snail during lung EMT.
