Species of the genus Tagetes are well known for their anti-inflammatory properties. Tagetes minuta "Huacatay" is an endemic species of South America that has been used in traditional medicine since ancient times as a remedy for stomach and intestinal discomfort.

The aim of this study is to investigate the anti-inflammatory activity of the aqueous and hydroalcoholic extracts of the Huacatay, identifying the compounds responsible for this activity.

Anti-inflammatory activity of the compounds, fractions and extracts was evaluated in Hs 746T (stomach), HIEC-6 (intestine) and THP-1 (monocytes peripheral blood) cells by measuring their inhibitory capacity against the NF-κB production.

Aqueous and hydroalcoholic extracts of Tagetes minuta displayed anti-inflammatory activity in vitro, the hydroalcoholic extract being the most active (IC

between 59.72 and 66.42μg/mL) in all cell lines. Bio-guided hydroalcoholic extract fractionation led to the isolation and characterisation of two pheophytins, pheophytin a (1) and 13

-hydroxy pheophytin a (2). Both compounds inhibited the production of NF-κB with IC

values in the low micromolar range, with an IC

between 12.32 and 16.01μM for compound 1 and 7.91-9.87μM for compound 2.

The two pheophytins isolated in this study inhibit the production of NF-κB, thus showing that the traditional anti-inflammatory use of Tagetes minuta can be proved through pharmacological assays. This contributes to understanding the anti-inflammatory activity of the Huacatay extracts and their use in the treatment of stomach and intestinal discomfort.

This study aimed at determining the effects of saffron on depression as well as its neuroprotective and pharmacological effects on the intestinal function of crocetin in mice exposed to chronic restraint stress.

Chronic stress was induced in two-week-old ICR mice by immobilizing them for 6h per day for 28 days. The mice were orally administered with crocetin (20, 40, 80mg/kg), fluoxetine (20mg/kg) or distilled water. The treatments were administered daily and open field and tail suspension tests were performed. Immunofluorescent and Western-bolt (WB) assays were conducted to determine the expression of mitogen-activated protein kinase phosphatase-1 (MKP-1), the precursor of brain-derived neurotrophic factor (proBDNF), extracellular signal-regulated kinase 1/2 (ERK1/2), phosphorylated cAMP response element-binding (CREB) protein in the hippocampus. Serum levels of dopamine (DA), proBDNF, MKP-1 and CREB were measured by Elisa kits. High-throughput sequencing was carried out to analyze the composition of intecosystem.

A bleeding episode may herald cancer in the general population. Oral anticoagulants (OACs), the mainstay treatment for atrial fibrillation (AF), are known to increase the risk of bleeding, and may thus promote an earlier diagnosis of cancer. Data regarding the association of bleeding episodes with cancer in patients with AF on OACs are scarce.

In this systematic review and meta-analysis, we searched electronic databases (Medline, Scopus, and Central) and gray literature sources for studies of patients with nonvalvular AF under any OAC, from inception until 14 October 2020. The primary outcome was the association of bleeding occurrences with the detection of cancer. A subgroup analysis was performed according to OAC type [NOAC (non-vitamin K oral anticoagulant) versus VKA (vitamin K antagonist)].

Overall, 4 studies were included, accounting for a total of 144,362 patients with AF receiving OAC. During follow-up, 816 (0.57%) cases of cancer were confirmed. The presence of a bleeding event, either major or minor, was associated with a higher risk for cancer detection (odds ratio [OR] 8.79, 95% confidence interval [CI] 4.98-15.51, and I

85%). Heterogeneity was explained after studies were stratified by the type of OAC (NOACs OR 6.12, 95% CI 4.47-8.37, I

0%, VKAs OR 15.16, 95% CI 12.61-18.23, and I

0%).

The detection of a bleeding event could be an alerting sign of cancer in patients with AF on OACs, particularly in patients receiving VKAs. REGISTRATION NUMBER (DOI) available in https//doi.org/10.17605/OSF.IO/3948R, DOI 10.17605/OSF.IO/3948R.

This study aimed to identify specific gene transcripts of atrial inflammation, inflammatory handling, and oxidative stress associated with POAF. Left atrial tissue was obtained from 50 patients undergoing intended degenerative mitral repair who did not have any of the following risk factors for POAF history of atrial fibrillation or other arrhythmia, left atrial diameter greater than 6.0 cm, or left ventricular ejection fraction less than 40%. Isuzinaxib Postoperative outcomes and left atrial tissue messenger ribonucleuc acid (mRNA) levels were recorded. Parametric 2-sample t-tests and chi-square tests were used to evaluate for statistical significance in comparing POAF and non-POAF groups. Within 30 days of surgery, 19 of 50 of patients (38%) developed POAF. There were no significant preoperative, intraoperative, or postoperative differences between POAF and non-POAF patients. In the tissue transcriptome analysis, POAF patients were found to have a worse preoperative inflammatory state with higher levels of tumor necrosis factor alpha, Interleukin-6, and nuclear factor of kappa light polypeptide gene enhancer in B-cells mRNA, worse inflammatory handling capacity with lower levels of nuclear factor of kappa light polypeptide gene enhancer in B-cells inhibitor mRNA, and reduced antioxidant defenses with lower levels of glutathione synthetase, glutathione reductase, and mitochondrial superoxide dismutase 2 mRNA. This study found POAF patients to have preoperative left atrial tissue profiles suggestive of more inflammation, worse inflammatory handling, and reduced antioxidant defenses against oxidative stress. Investigation of therapies targeted to the tissue-specific inflammatory transcriptome of POAF patients is warranted.
