Gastrointestinal stromal tumors (GIST) commonly recur following curative-intent resection. Patients with recurrent GIST display heterogeneous outcomes with limited prognostic tools. We investigated factors associated with post-recurrence survival (PRS) and progression-free survival (PFS).

We performed a review of our institutional cancer registry from 2003 to 2018 for patients with GIST. Clinicopathologic and outcome data were collected. The disease-free interval (DFI) was calculated from the end of curative-intent oncologic therapy until recurrence. Outcomes were evaluated using Kaplan-Meier and Cox proportional hazards modeling.

Overall, 254 patients underwent resection of primary, non-metastatic GIST, with 81 (32%) recurrences. The median age was 58 years and more than half of the patients with recurrence (n=44; 54%) received adjuvant imatinib. Recurrence was most common in the liver (n=34, 42%), peritoneum (n=31, 38%), or liver plus peritoneum (n=10, 12%). The median DFI was 14 months (interquartileetastasectomy.Parkinson's disease (PD) is often associated with a vast list of gait-associated disabilities, for which there is still a limited pharmacological/surgical treatment efficacy. Therefore, alternative approaches have emerged as vibrotactile biofeedback systems (VBS). This review aims to focus on the technologies supporting VBS and identify their effects on improving gait-associated disabilities by verifying how VBS were applied and validated with end-users. It is expected to furnish guidance to researchers looking to enhance the effectiveness of future vibrotactile cueing systems. The use of vibrotactile cues has proved to be relevant and attractive, as positive results have been obtained in patients' gait performance, suitability in any environment, and easy adherence. VX-765 Caspase inhibitor There seems to be a preference in developing VBS to mitigate freezing of gait, to improve balance, to overcome the risk of fall, and a prevalent use to apply miniaturized wearable actuators and sensors. Most studies implemented a biofeedback loop able to provide rescue strategies during or after the detection of a gait-associated disability. However, there is a need of more clinical evidence and inclusion of experimental sessions to evaluate if the biofeedback was effectively integrated into the patients' motor system.Two novel Gram-negative, rod-shaped bacterial strains BT702T and BT704T were isolated from soil collected in Jeongseon (37° 22' 45″ N, 128° 39' 53″ E), Gangwon province, South Korea. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strains BT702T and BT704T belong to distinct lineage within the genus Spirosoma (family Cytophagaceae, order Cytophagales, class Cytophagia and phylum Bacteroidetes). The strain BT702T was closely related to Spirosoma flavus 15J11-2T (96.7% 16S rRNA gene similarity) and Spirosoma metallilatum TX0405T (93.3%). The strain BT704T was closely related to Spirosoma koreense 15J8-5T (94.6%), Spirosoma endophyticum DSM 26130T (93.8%) and Spirosoma humi S7-4-1T (93.8%). The genome sizes of type strains BT702T and BT704T are 8,731,341 bp and 8,221,062 bp, respectively. The major cellular fatty acids of strains BT702T and BT704T were C161 ω5c and summed feature 3 (C161 ω6c/C161 ω7c). The strains were found to have the same quinone system, with MK-7 as the major respiratory quinone. The major polar lipids of strain BT702T was identified to be phosphatidylethanolamine (PE), aminophospholipid (APL) and aminolipid (AL), while that of strain BT704T consisted of phosphatidylethanolamine (PE) and aminophospholipid (APL). Based on the polyphasic analysis (phylogenetic, chemotaxonomic and biochemical), strains BT702T and BT704T can be suggested as two new bacterial species within the genus Spirosoma and the proposed names are Spirosoma profusum and Spirosoma validum, respectively. The type strain of Spirosoma profusum is BT702T (= KCTC 82115T = NBRC 114859T) and type strain of Spirosoma validum is BT704T (= KCTC 82114T = NBRC 114966T).Two-dimensional MXene-based materials are potential of presenting unique catalytic performances of electrocatalytic reactions. The surface functionalization of MXene-based catalysts is attractive for developing efficient electrocatalysts toward nitrogen reduction reaction. Herein, we reported a Ti3C2Tx MXene with a medium density of surface functionalized fluorine terminal groups, as an excellent N2 reduction reaction electrocatalyst with enhanced adsorption and activation of N2. The Ti3C2Tx MXene catalyst showed a production rate of ammonia as 2.81 × 10-5 μmol·s-1·cm-2, corresponding to a partial current density of 18.3 μA·cm-2 and a Faradic efficiency of 7.4% at - 0.7 V versus reversible hydrogen electrode in aqueous solutions at ambient conditions, substantially exceeding similar Ti3C2Tx MXene catalysts but with higher or lower densities of surface fluorine terminal groups. Our work suggests the capability of developing surface functionalization toolkit for enhancing electrochemical catalytic activities of two-dimensional MXene-based materials.Due to their neurodevelopmental toxicity, flame retardants (FRs) like polybrominated diphenyl ethers are banned from the market and replaced by alternative FRs, like organophosphorus FRs, that have mostly unknown toxicological profiles. To study their neurodevelopmental toxicity, we evaluated the hazard of several FRs including phased-out polybrominated FRs and organophosphorus FRs 2,2',4,4'-tetrabromodiphenylether (BDE-47), 2,2',4,4',5-pentabromodiphenylether (BDE-99), tetrabromobisphenol A, triphenyl phosphate, tris(2-butoxyethyl) phosphate and its metabolite bis-(2-butoxyethyl) phosphate, isodecyl diphenyl phosphate, triphenyl isopropylated phosphate, tricresyl phosphate, tris(1,3-dichloro-2-propyl) phosphate, tert-butylphenyl diphenyl phosphate, 2-ethylhexyl diphenyl phosphate, tris(1-chloroisopropyl) phosphate, and tris(2-chloroethyl) phosphate. Therefore, we used a human cell-based developmental neurotoxicity (DNT) in vitro battery covering a large variety of neurodevelopmental endpoints. Potency according to the respective most sensitive benchmark concentration (BMC) across the battery ranked from 10 μM range (3 FRs).
