In the present work the effect of ferroalumina addition as a raw material was examined by smelting ferroalumina, blast furnace-slag, lime and scrap at 1550°C in a graphite crucible and a constant slag basicity. The increase of the alumina content in the slag improves the desulfurization capacity. Moreover, the silicon exchange between slag and metal was examined. The results indicate that the alkalis' capacity of the slag increases with the addition of ferroalumina. The analysis of the finally obtained slag suggests that it could be suitable for utilization in slag-cement production.Reproductive health is a major concern for workers constantly exposed to chemicals at work, especially in developing countries. The problems mainly stemmed from chronic exposure to the chemicals contained in paint thinner, which is mainly toluene, used during automobile painting. Unfortunately, in Indonesia, there is no study on the reproductive health of male workers in automobile workshops, especially in relation to spermatogenesis. This study aimed to explore the possibility of reproductive problems, namely spermatozoa DNA fragmentation, among male workers in an automobile workshop in Malang. We recruited workers who have worked as automobile painters for years at an automobile workshop in Malang and have been chronically exposed to thinner. Semen samples were collected from 15 automobile workshop workers who were married and had children. Twelve office workers were used as the control group. The two groups of semen samples were tested with the terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling assay combined with propidium iodide and analyzed by flow cytometry. The results showed a significant difference between DNA fragmentation of the control group and workshop workers at 14.9% and 47.66%, respectively. Risk factor analysis showed a significant increase in risk factors (p = 0.001). Myricetin Taken together, chronic exposure to paint thinner in those engaged in painting at the automobile workshop increased the risk of DNA fragmentation in spermatozoa. Our study highlighted the importance of health education for the risked workers on minimization of exposure, which could be recommended to the health policy makers.
Previous study (
2017; 176498) reported that CD56 positive is associated with poor prognosis of patients with intermediate-risk acute myeloid leukemia (IR-AML). However, our data were inconsistent with the finding
Thus, in this study, we provided the different results to discuss.
A total of 262 bone marrow transcriptomic data of IR-AML in the GSE12417-GPL96 and GSE71014-GPL-10558 from the Gene Expression Omnibus database (GEO) database, and 92 IR-AML patients from the cancer genome atlas (TCGA) database were obtained for prognostic analysis and validation.
Compared with low CD56 expression, IR-AML patients with high CD56 expression had a longer overall survival (OS) time and restricted mean survival time (RMST) and favorable OS rate in the GSE12417-GPL96 dataset. These results were confirmed in both GSE71014-GPL-10558 and TCGA datasets. Importantly, the inconsistency between our findings and the previous finding may be due to the following reasons different detection methods, age stratification, countries, treatment options etc.
The prognostic value of CD56 expression in IR-AML may need to be comprehensively evaluated based on different detection methods, age stratification, countries, treatment options, and other factors. If confirmed, CD56 may be a biomarker for further risk stratification for IR-AML patients.

This small series includes three patients and should be seen as a first suggestion of integration of the dose density and the maintenance chemotherapy concept. The IrIVA regimen (irinotecan, ifosfamide, vincristine, and actinomycin-D) is added-used at a short interval between chemotherapy administrations-at more classic intensive ifosfamide-based regimens. The vinorelbine and low-dose oral cyclophosphamide maintenance therapy is added at the end of conventional chemotherapy to achieve an antiangiogenic effect.
Intermediate-risk acute myeloid leukemia (IR-AML) without FLT3-ITD, NPM1 and biallelic CEBPA mutations (here referred to as NPM1
CEBPA
FLT3-ITD
AML) is a clinically heterogeneous disease. The optimal post-remission therapy (PRT) is unclear for patients with NPM1
CEBPA
FLT3-ITD
AML who achieved first complete response (CR1). This study aims to explore clinical and molecular factors that can help determine the prognosis of those patients and their choice of PRT.
We retrospectively analyzed 28 patients with NPM1
CEBPA
FLT3-ITD
AML who received induction chemotherapy and achieved CR1. For PRT, 17 patients received post-remission chemotherapy (PR-CT) and 11 patients received allogeneic hematopoietic stem cell transplantation (allo-HSCT).
For patients with NPM1

AML, multivariate analysis indicated that allo-HSCT and negative minimal residual disease (MRD
) before PRT were favorable prognostic factors of overall survival (OS) (allo-HSCT,

,
= 0.018); whereas relapse was an adverse prognostic factor of OS (
= 0.003). Log-rank analysis showed that allo-HSCT significantly improved their OS and RFS compared with PR-CT (OS,
< 0.001; RFS,

For patients with NPM1mut-negCEBPAdm-negFLT3-ITDneg AML, MRDneg before PRT and allo-HSCT were favorable prognostic factors of OS. Whether they obtain MRDneg or not, allo-HSCT is the preferred PRT.
