Identifying transcription factors controlling the basal expression of human MRP4 highlights a substantial role for Sp1

FEBS Open Bio, EarlyView.
The MRP4 transporter exports several drugs and signaling molecules. Here, we identified key promoter elements regulating basal MRP4 expression. Using reporter assays, we defined a conserved region with essential Sp1 and contributory Ets sites, which controlled basal MRP4 expression.

Experimental Evaluation of 100Cr6 Steel Microindented Surfaces Under Lubricated Nonconformal Point Contacts

Advanced Engineering Materials, EarlyView.
The tribological behavior of 100Cr6 steel spheres textured via Vickers microindentation is evaluated under lubricated sliding by varying both dimple size and density. Fine and dense textures significantly reduce friction across all lubrication regimes, while large dimples increase it.

Study on zinc removal behavior in simulated pre-reduction sintering process [PDF]

Archives of Metallurgy and Materials
In this study, blast furnace dust and iron concentrate were used as raw materials and graphite as reducing agent for mixed compacts. The briquettes were roasted in a high temperature tube furnace at 1200°C and kept for a certain time to simulate the pre ...

Management of supraerupted maxillary molars in an adult patient using orthodontic miniscrew implants: A pre-prosthodontic therapy

Indian Journal of Dental Research, 2020
The sequelae of chronic edentulous space is the supraeruption of the opposing teeth which hinders prosthodontic replacement. Molar intrusion of overerupted teeth can be done using miniscrew implants which serves as a promising technique, especially in ...

Interactions between Molten High‐Silicon Electrical Steels and Carbon‐Bonded MgO Refractories Based on Recyclates

Advanced Engineering Materials, EarlyView.
This study examines how several molten high‐silicon electrical steels interact with both conventional and recycled MgO–C refractories. For this, various immersion experiments are conducted. In addition to infiltration, a number of mechanisms are identified and explained that control the corrosion of the refractory material.

Interaction between Molten Al‐Killed Mn–B Steel and Carbon‐Bonded MgO Refractories Based on Recyclates

Advanced Engineering Materials, EarlyView.
High‐temperature interactions between low‐sulfur Al‐killed Mn–B steel and MgO–C refractories (0 and 50 wt% recyclates) are studied via finger immersion tests (1600 °C). Surface‐active elements influence infiltration. MgO/CaS layer forms, along with spinel and calcium silicate.

Hubungan Kadar βHCG Praevakuasi, Gambaran Histopatologi, dan Kista Lutein dengan Performa βHCG pada Penderita Mola Hidatidosa yang Berkembang Menjadi PTG dan Kembali Normal

Majalah Kedokteran Bandung, 2014
The incidence of trophoblastic diseases in Indonesia and developing countries is relatively high compared to the developed countries. The incidence of gestational trophoblast tumors (GTT) after the evacuation of a hydatidiform mole ranges from 10% to 20%.
