For extending the current collection of axenic cultures of planctomycetes, we describe in this study the isolation and characterisation of strain Pan265T obtained from a red biofilm in the hydrothermal vent system close to the Lipari Islands in the Tyrrhenian Sea, north of Sicily, Italy. The strain forms light pink colonies on solid medium and grows as a viscous colloid in liquid culture, likely as the result of formation of a dense extracellular matrix observed during electron microscopy. Cells of the novel isolate are spherical, motile and divide by binary fission. Strain Pan265T is mesophilic (temperature optimum 30-33 °C), neutrophilic (pH optimum 7.0-8.0), aerobic and heterotrophic. The strain has a genome size of 3.49 Mb and a DNA G + C content of 63.9%. Phylogenetically, the strain belongs to the family Phycisphaeraceae, order Phycisphaerales, class Phycisphaerae. Our polyphasic analysis supports the delineation of strain Pan265T from the known genera in this family. Therefore, we conclude to assign strain Pan265T to a novel species within a novel genus, for which we propose the name Mucisphaera calidilacus gen. nov., sp. nov. The novel species is the type species of the novel genus and is represented by strain Pan265T (= DSM 100697T = CECT 30425T) as type strain.A first compilation of georeferenced tick locations in Austria and South Tyrol, Italy, is presented here. This allows the tick fauna to be examined in the various climatic regions of the European Alps. The dataset comprises 424 tick locations of Austria and 48 tick locations of South Tyrol, which were digitized from literature and visualized in the form of geographical maps. The tick fauna of Austria includes two species of Argasidae in the genera Argas and Carios and 15 species of Ixodidae in the genera Dermacentor, Haemaphysalis, and Ixodes, altogether 17 tick species. In addition, two species of Ixodidae in the genera Hyalomma (each spring imported by migratory birds) and Rhipicephalus (occasionally imported by dogs returning from abroad with their owners) are included in the tick atlas. Of these, the georeferenced locations of 18 tick species are depicted in maps. The occurrence of the one remaining tick species, Ixodes inopinatus, is given at the level of the federal states. The first Austrian distributifor new species distribution models.Jasmonates induce the protein-protein interaction between the F-box protein CORONATINE INSENSITIVE 1 (COI1) and jasmonate ZIM-domain proteins (JAZs) in the presence of inositol phosphate, which made the degradation of JAZs and the release of the JAZ-repressed transcription factors. They are involved in the regulation of a wide range of physiology process, including plant growth, development and stress response. Coronatine-O-methyloxime (COR-MO) prevents the binding of COI1-JAZ, acting as an antagonist for jasmonate signaling pathway, while the understanding on the molecular basis of its action as an antagonist is still lacking at atomic level. In this study, we explored the interaction mechanism of jasmonate antagonists through molecular docking, molecular dynamics (MD) simulation, residue interaction network analysis and binding free energy calculation. Compared with the agonists, the conformation of JAZ1 is different in response to the binding with antagonist. Antagonists lost hydrogen bond interaction with Ala204 and Arg206 in JAZ1, and Arg496 in COI1, which results that the sidechain of Arg206 in JAZ1 rotates and unable to penetrate into COI1, so that it lost interaction with 1,5-InsP8. It is indicated that the agonist is more closely associated with 1,5-InsP8 than the antagonist based on the residue interaction network analysis. The binding free energy of JA-Ile-MO/COR-MO with JAZ1 is higher than that of JA-Ile/COR. It is unfavorable for the binding of JAZ1 with COI1 in the presence of antagonists. This study provides a basis for the understanding of the interaction mechanism of jasmonate agonists/antagonists, which will contribute to the discovery of novel jasmonate agonists/antagonists.
The standard treatment for unresectable advanced/recurrent esophageal cancer in Japan is 5-fluorouracil plus platinum-containing drugs as first-line chemotherapy and taxanes as second-line chemotherapy. However, the standard regimen after patients become refractory to these treatments remains to be established. Therefore, we investigated the efficacy of trifluridine/tipiracil (FTD/TPI) in patients with esophageal cancer who are refractory or intolerant to 5-fluorouracil, platinum-containing drugs, and taxanes.
This single-arm phase II trial was conducted in seven hospitals in Japan. Eligible patients were those with unresectable advanced/recurrent esophageal cancer that was refractory or intolerant to 5-fluorouracil, platinum-containing drugs, and taxanes. The primary endpoint was the 3-month progression-free survival rate, and the secondary endpoints were the 6-month progression-free survival rate, progression-free survival, overall survival, response rate, disease control rate, and toxicity.

Transanal total mesorectal excision (TaTME) is the most recent approach developed to improve pelvic dissection in surgery for mid and low rectal tumors. There are still inconsistencies regarding the technique's oncological results. The aim of this study was to analyze clinical and oncological outcomes of the learning curve of TaTME in comparison to laparoscopic TME (lapTME).
Rectal cancer patients who had TaTME and lapTME in two Portuguese colorectal units between March 2016 and December 2018 were eligible. Primary endpoints were 5-year overall survival, disease-free survival, and local recurrence. Secondary endpoints were clinical and pathological outcomes.
Forty-four patients underwent TaTME (29 men) and 39 lapTME (27 men) with a median age of 69 and 66 (p = 0.093), respectively. No differences were observed concerning baseline characteristics, emphasizing their comparability. In the TaTME group, there were more hand-sewn anastomosis (0 lapTME versus 7 TaTME, p = 0.018) with significantly less distancwever, a demanding learning curve, significant risk for morbidity and should be used only for selected patients.The structures and energetics of the binuclear cyclobutadiene vanadium carbonyls (C4H4)2V2(CO)n (n = 8, 7, 6, 5, 4, 3, 2) have been investigated by density functional theory (DFT). The lowest energy (C4H4)2V2(CO)8 structure consists of two C4H4V(CO)4 units linked by a V-V single bond of length 3.4 Å. The two lowest energy (C4H4)2V2(CO)7 structures also have formal V-V single bonds. The "extra" two electrons to give each vanadium atom in these heptacarbonyls the favored 18-electron configuration can come from either an agostic C-H-V interaction activating a hydrogen atom from one of the cyclobutadiene rings or from a four-electron donor bridging η2-µ-CO group with a short V-O distance. The lowest energy (C4H4)2V2(CO)6 structure has a formal V≡V triple bond of length 2.52 Å similar to the V≡V triple bond of length 2.46 Å found in the experimentally known cyclopentadienyl derivative (η5-C5H5)2V2(CO)5. The lowest energy structures for the more highly unsaturated (C4H4)2V2(CO)n (n = 5, 4, 3, 2) have at least two four-electron donor bridging η2-µ-CO groups and a vanadium-vanadium bond order sufficient to give each vanadium atom at least a 16-electron configuration. The structures and energetics of the binuclear cyclobutadiene vanadium carbonyls (C4H4)2V2(CO)n (n = 8, 7, 6, 5, 4, 3, 2) have been investigated by density functional theory. The two lowest energy (C4H4)2V2(CO)7 structures include one with an agostic C-H-V interaction activating a hydrogen atom from one of the cyclobutadiene rings and another with a four-electron donor bridging η2-µ-CO group with a short V-O bonding distance.
The Ministry of Health and Population (MOHP)-Family Planning Sector (FPS) has a strong management information system (MIS) that allows the flow of data from MOHP-FP clinics, health districts, and governorates up to the central level. Yet, family planning (FP) quarterly reports issued at the central level are presented as database/spreadsheet software documents. These data are not used to provide indicators or information that aid in decision-making or the tracking of FP services over time. The objective of the study is to organize data in the database, develop key performance indicators, and design FP reports and policy briefs.
The study is operations research that is driven by published data derived from MOHP-FP sector-head, and 2014 service statistics quarterly hardcopy reports. The information was entered into an excel program, and 15 key performance indicators (KPIs) were calculated and used to rank Egypt's 27 governorates. We developed an annual FP report form, settled tables, and colored graphs thatsion-makers at all levels and their tracking overtime will guide them to timely decision-making for improving performance in FP services at all levels.
MOHP-FP sector service statistics data could be used for the development of fifteen key performance indicators. Having those indicators at governorate, district, and central levels in quarterly and annual reports and their communication with decision-makers at all levels and their tracking overtime will guide them to timely decision-making for improving performance in FP services at all levels.
Completely obstructed benign biliary strictures (BBS) is a difficult-to-treat condition. Regorafenib Surgery is the main treatment modality with high morbidity and mortality. Recently, the magnetic compression anastomosis (MCA) technique was employed in such cases with low complication rates.
To evaluate the effectiveness of the MCA in completely obstructed BBS.
21 MCA procedures were performed in 19 patients with completely obstructed BBS. All patients had percutaneous biliary access. Magnets were located to the proximal side of the obstruction via percutaneous biliary sheath and the distal side endoscopically. The procedure was terminated as the magnets attracted. Either self-expandable fully covered metallic stent and/or a growing number of plastic stents were introduced after recanalization was achieved.
A total number of 19 patients with completely obstructed BBS resulting from cholecystectomy or liver transplant underwent 21 MCA procedures. Among those, 19 (90.5%) interventions were successful. The median stricture length that had been measured after magnet attraction was 4mm (range 1-10mm). The median magnet coupling time in successful cases was 9days (range 4-27days). No correlation was found between magnet coupling time and stricture length (p = 0.27). Complications were observed in 6 (cholangitis1, magnet migration2, magnet entrapment3) of 19 successful MCA procedures. Fifteen of the 19 successful procedures had at least a period of stent-free follow-up. Recurrence of stenosis occurred in 7 procedures, of which 4 remained stent-free with retreatment. Eventually,12 procedures had stent-free last status.
MCA is an effective and safe treatment option in completely obstructed BBS. Further studies are required for procedural standardization.
