Management of acute limb ischemia (ALI) due to occlusions in popliteal and infrapopliteal arteries remains a challenge. Open surgical methods and even the novel percutaneous mechanical thrombectomy devices have not shown satisfactory results in these small arteries. The aim of this prospective study was to assess the safety and efficacy of catheter-directed thrombolysis (CDT) in this type of ALI with distal occlusion. Between April 2017 and June 2019, 22 patients with ALI secondary to popliteal or infrapopliteal occlusion were enrolled in the study. Patients with thrombosis, embolism, and thrombosed bypass graft were included; all belong to category I or IIa of Rutherford's classification. Technical success, limb salvage, complications, and mortality were evaluated at short- and long-term follow-up. Technical success was achieved in 81.8%, while 36.4% of patients needed additional balloon angioplasty, major amputation in 13.6%, minor bleeding in 18.2%, and no major hemorrhage. Limb salvage at 30 days and 1 year was 86.4% and 72.7%, respectively. At 1 year, primary patency was 63.6% and mortality was 9.1%. Catheter directed thrombolysis is a safe and highly effective treatment modality for popliteal or infrapopliteal acute limb ischemia unless contraindicated.

NRG Oncology, part of the National Cancer Institute's National Clinical Trials Network, took efforts to increase patient-reported outcome measures (PROMs) completion and institutional data submission rates within clinical trials. Lack of completion diminishes power to draw conclusions and can be a waste of resources. It is hypothesized that trials with automatic email reminders and past due notifications will have PROM forms submitted more timely with higher patient completion.

Automatic emails sent to the research associate were added to selected NRG Oncology trials. Comparisons between trials with and without automatic emails were analyzed using Chi-square tests with respect to patient completion and timeliness of form submission rates. Multivariable analyses were conducted using repeated measures generalized estimating equations. If PROMs were not completed, a form providing the reason why was submitted and counted towards form submission.

For both disease sites, form submission was significantly higher within 1 month of the form's due date for the studies with automatic emails vs. those without (prostate 79.7% vs. 75.7%, p < 0.001; breast 59.2% vs. 31.3%, p < 0.001). No significant differences in patient completion were observed between the breast trials. The prostate trial with automatic emails had significantly higher patient completion but this result was not confirmed in the multivariable analysis.

Although patient completion rates were higher on trials with automatic emails, there may be confounding factors requiring future study. The automatic emails appeared to have increased the timeliness of form submission, thus supporting their continued use on NRG Oncology trials.

The latest research on its Asian representatives has been done only with mitochondrial or sole nuclear markers. see more In the present study we compare the results of phylogenetic reconstructions, based on mitochondrial, on single nuclear genes and on multiple nuclear markers analyzed using the MRP algorithm (Matrix representation with parsimony) for representative species from all the main species groups. MRP analysis provides the most supported and well-interpretable phylogeny. Our data indicate monophyly of the large Asian leaf-nosed bats which suggests they are an independent taxon of the subgenus rank, as well as monophyly of several species complexes which are paraphyletic according to mtDNA analysis.ABSTTRACT -Using the methods of geometric morphometrics, we have revealed the phenomenon of geographical variability of morphogenetic trajectories when doing side-by-side comparisons of mandibular shapes in individuals of different ages from three southern Trans-Ural populations of the mole vole (Ellobius talpinus Pall.) in the common morphospace.The influence of pre-sowing treatment of spring wheat seeds with combined use of plant growth hormones and sorption preparations based on bentonite-humate mixtures on seeds germination and their development in soils was studied. In some cases, the combined use of plant growth hormones and the sorption preparation (CB-H-BYA) that can decrease the intake of allelotoxins from soil to seeds allows noticeably increasing the efficiency of plant growth hormones used for pre-sowing treatment. The inclusion of cytokinins (6-benzylaminopurine, kinetin, and forchlorophenuron) into the sorption preparation (CB-H-BYA) had markedly different effects on seeds germination. The addition of Polysorbate 20 to the sorption preparation (CB-H-BYA) leads to an increase in the effectiveness of its action on seed germination.The role of two heat shock proteins, Hsp70 and Hsp90α, on stress response in mice with severe diabetes mellitus induced by a high dose of alloxan (500 mg/kg body weight), as well as in RIN-m5F β cells cultured in the presence of cytokines (IL-1 and TNF-α) was studied. Our results showed that severe type 1 diabetes mellitus (T1D) caused a higher expression of Hsp90α, but not Hsp70. Moreover, injections of the peroxiredoxin 6 antioxidant enzyme (PRDX6) did not affect the expression of these chaperones. Conversely, pro-inflammatory cytokines added to β-cells caused a significant increase in the expression of Hsp90α and, substantially, Hsp70. Moreover, cells cultivated in the presence of PRDX6 were more susceptible to the cytokine effect. Thus, in the course of severe alloxan-induced T1D, no protective role of the heat shock proteins, was revealed, and their expression level was not increased by PRDX6. At the same time the protective potential of these proteins was shown in vitro with the use of RIN-m5F β cells. Thus, the system of heat shock proteins was unable to prevent the devastating effects of severe T1D accompanied by high animal mortality.
