The top 10 hub genes - COL1A1, COL3A1, COL1A2, BGN, COL5A2, THBS2, TIMP1, SPP1, PDGFRB, and COL4A1 - were distinguished from the PPI network. These 10 hub genes were shown to be significantly upregulated in gastric adenocarcinoma tissues in GEPIA. Prognostic analysis of the 10 hub genes via UALCAN showed that the upregulated expression of COL3A1, COL1A2, BGN, and THBS2 significantly reduced the survival time of gastric adenocarcinoma patients. Module analysis revealed that gastric adenocarcinoma was related to 2 pathways including focal adhesion signaling and ECM-receptor interaction. CONCLUSIONS This research distinguished hub genes and relevant signal pathways, which contributes to our understanding of the molecular mechanisms, and could be used as diagnostic indicators and therapeutic biomarkers for gastric adenocarcinoma.Pseudomonas putida (P. putida) is a rare pathogen that causes various infections in newborns, neutropenic and cancer patients, or in patients with risk factors leading to immunosuppresion. Antibiotic resistance in P. putida is seen in growing numbers. Although it is less virulent compared to Pseudomonas aeruginosa, mortal infections are reported. Here, a P. putida case after an invasive procedure in a patient with gastrointestinal malignancy is reported. Although, it caused an antibiotic resistant bacteremia, it resolved spontaneously without any treatment. P. Putida might have lower virulence and a different antibiotic susceptibility when compared to Pseudomonas aeruginosa in different cases. More clinical information is needed for further evaluation.

They are considered to be within the most relevant group of neglected tropical diseases and have been included as priorities for searching new drugs due to their several treatment limitations. These parasitic diseases caused by flagellated protozoans affect more than 20 million people predominantly in developing countries. METHODOLOGY In this study, we prepared a series of 2-substituted 1,4-benzenediols by an efficient, green, and lithium salt-free synthesis in water/ethanol as solvent to test their anti-parasitic activity. All 36 phenolic derivatives were evaluated in vitro for their activity against T. cruzi epimastigotes, L. infantum, and L. braziliensis promastigotes, as well as their cytotoxicity on macrophage and fibroblast cell lines. RESULTS Based on the results obtained, the compounds that presented a methyl, trifluoromethyl or bromo group at the para-position of the second benzene ring were found the most active analogs, with higher selective index values on the three parasites assayed. CONCLUSION This evidence suggests that the anti-parasitic activity observed in these analogs is affected by the size of the group at the 4-position of the second ring, but not related with electronic factors.This study identified hit compounds with the potential to target several kinetoplastid parasites.

The aim is to precisely evaluate the molecular and biochemical remarks of miltefosine on Toxoplasma gondii accidental infection during miltefosine therapeutic course. METHODOLOGY changes implied by miltefosine daily parenteral administration to Toxoplasma-infected mice, subcutaneously or intraperitoneal, have been investigated. Tumor necrosis factor-Alfa, immunoglobulin G and M, IL-12 and interferon-gamma release assay (IGRA) were measured in the animals' sera post-miltefosine administration in addition to monitoring Tissue parasite load by measuring the daily changes of copy number of B1 gene using quantitative PCR technique (qPCR). RESULTS Miltefosine significantly increased inflammatory and immunological markers (TNF-α, IgG and IgM) measured on reference to control untreated group, with a significant increase in the parasite burden and distribution in all tested organs (F = 390.9, df = 9, P less then 0.0001), (F = 4478.98, df = 4.75, P less then 0.0001) and (F = 247.3, df = 4, P less then 0.0001); heart, liver and lung, respectively, using MANOVA. Releasing capability of macrophages significantly increased during the first day of infection, however, it finally declined after seven consecutive doses of miltefosine (t = 7.96, P less then 0.001). CONCLUSION Miltefosine could not control the pathogenesis and multiplication of accidental Toxoplasma infection. Cumulative low parenteral daily doses of miltefosine (1.5 µM) could inversely affected the normal humoral immunity against toxoplasmosis. Therefore, a periodical screening for accidental Toxoplasma infection during the course of therapy is strongly recommended.

Cryptococcus species are frequently isolated from trees and bird excreta in the environment and infection occurs by inhalation of propagules dispersed in the air. The aim was to investigate Cryptococcus species in bird excreta and tree hollows located in a university hospital area and in an academic area of a university campus. learn more METHODOLOGY A total of 40 samples of bird excreta and 41 samples of tree hollows were collected. The identification of the isolates was done by classical methodology and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry. RESULTS Twenty (62.5%) isolates of Cryptococcus were found in bird excreta and 12 (37.5%) in tree hollows. C. laurentii (currently Papiliotrema laurentii) was the most frequent species in both samples, being found in 5 samples of excreta and in 8 tree hollows. The diversity of species found in excreta (C.
