Human cognitive performance can be significantly influenced by the presence of audience members. While often associated with reputation management, which is considered uniquely human, it is unclear to what degree this phenomenon is shared with non-human animals. To investigate such audience effects in chimpanzees, we recorded the performance of six chimpanzees on three different numerical touch screen tasks varying in difficulty and cognitive demand, in the presence of variable audience member compositions over six years.

Multiple myeloma (MM) remains a difficult-to-treat disease even with the latest therapeutic advances due to the complex, overlapping, and heterogeneous cytogenetic, genetic, and molecular abnormalities. To address this challenging problem, we previously identified the universal and critical roles of RSK2 and AKT, the effector signaling molecules downstream of PDPK1, regardless of cytogenetic and genetic profiles. Based on this, in this study, we investigated the anti-myeloma potency of TAS0612, a triple inhibitor against RSK, including RSK2, AKT, and S6K.

We classified subtypes of hematologic cancer in Japan's National Cancer Registry (NCR) in 2016 by ICD-O-3 code and compared numbers with the Japanese Society of Hematology's Blood Diseases Registry (BDR). We reviewed data for individual cases, and calculated incidence per 100,000. NCR reported 67,919 cases of hematological cancer, including diffuse large B-cell lymphoma, Not Otherwise Specified (NOS) (11.

Article Synopsis
  • - In the KEAP1-NRF2 system, KEAP1 detects oxidative and electrophilic stresses using unique bonds, raising questions about how these sensors work in living organisms and whether they sense different types of stress through similar or distinct mechanisms.
  • - Research utilizing genetically modified mice indicated that while a lack of certain selenoproteins leads to heightened NRF2 activation, removing critical KEAP1 cysteine residues prevents this activation, suggesting differentiated roles in stress sensing.
  • - The study found that a single modification in KEAP1 can substantially impact its function and identified human genetic variations that affect oxidative stress sensors, but not electrophilic sensors, emphasizing the KEAP1 system's reliability in responding to oxidative stress.

Although dietary potassium restriction is an acceptable approach to hyperkalemia prevention, it may be insufficient for outpatients with chronic kidney disease (CKD). Most outpatients with CKD use community pharmacies owing to the free access scheme in Japan. The MieYaku-CKD project included a community pharmacist-led nutritional intervention for dietary potassium restriction, with the goal of determining its efficacy for patients' awareness of potassium restriction and serum potassium levels in outpatients with CKD.
