Impact of the Economic Status of the Patient's Country of Residence on the Outcome of Oncology Clinical Trials.

Background: Prolongation of overall survival (OS) is commonly evaluated as a primary endpoint in confirmative oncology clinical trials; however, it is potentially affected by subsequent treatments carried out in practice. To design and implement multi-regional clinical trials properly, we compared survival outcomes between Organisation for Economic Co-operation and Development (OECD) and non-OECD countries.

Materials And Methods: Individual patient data from industry-sponsored multi-regional phase III oncology trials were obtained from the Project Data Sphere.

A new protocol for the preparation of superconducting KBi.

A superconducting KBi sample was successfully prepared using a liquid ammonia (NH) technique. The temperature dependence of the magnetic susceptibility (/) showed a superconducting transition temperature ( ) as high as 3.6 K.

Preparation and characterization of a new graphite superconductor: CaSrC.

We have produced a superconducting binary-elements intercalated graphite, CaSrC, with the intercalation of Sr and Ca in highly-oriented pyrolytic graphite; the superconducting transition temperature, T , was ~3 K. The superconducting CaSrC sample was fabricated with the nominal x value of 0.8, i.

Photoelectron Holographic Atomic Arrangement Imaging of Cleaved Bimetal-intercalated Graphite Superconductor Surface.

From the C 1s and K 2p photoelectron holograms, we directly reconstructed atomic images of the cleaved surface of a bimetal-intercalated graphite superconductor, (Ca, K)C, which differed substantially from the expected bulk crystal structure based on x-ray diffraction (XRD) measurements. Graphene atomic images were collected in the in-plane cross sections of the layers 3.3 Å and 5.

Chemical analysis of superconducting phase in K-doped picene.

Potassium-doped picene (K3.0picene) with a superconducting transition temperature (T C) as high as 14 K at ambient pressure has been prepared using an annealing technique. The shielding fraction of this sample was 5.

Emergence of superconductivity in (NH3)yMxMoSe2 (M: Li, Na and K).

We report syntheses of new superconducting metal-doped MoSe2 materials (MxMoSe2). The superconducting MxMoSe2 samples were prepared using a liquid NH3 technique, and can be represented as '(NH3)yMxMoSe2'. The Tcs of these materials were approximately 5.

Recent progress on carbon-based superconductors.

This article reviews new superconducting phases of carbon-based materials. During the past decade, new carbon-based superconductors have been extensively developed through the use of intercalation chemistry, electrostatic carrier doping, and surface-proving techniques. The superconducting transition temperature T c of these materials has been rapidly elevated, and the variety of superconductors has been increased.

Emergence of Multiple Superconducting Phases in (NH3)yMxFeSe (M: Na and Li).

We previously discovered multiple superconducting phases in the ammoniated Na-doped FeSe material, (NH3)yNaxFeSe. To clarify the origin of the multiple superconducting phases, the variation of Tc was fully investigated as a function of x in (NH3)yNaxFeSe. The 32 K superconducting phase is mainly produced in the low-x region below 0.

The Female Encounter Test: A Novel Method for Evaluating Reward-Seeking Behavior or Motivation in Mice.

Background: Reduced motivation is an important marker of psychiatric disorders, including depression. We describe the female encounter test, a novel method of evaluating reward-seeking behavior in mice.

Methods: The test apparatus consists of three open chambers, formed with partitions that allow the animal to move freely from one chamber to another.

Pharmacological profile of encounter-induced hyperactivity in isolation-reared mice.

We have recently found that isolation-reared mice show hyperactivity during an encounter with an intruder. However, it is not known whether encounter-induced hyperactivity may model some aspects of psychiatric disorders. The present study examined the pharmacological profile of encounter-induced hyperactivity in isolation-reared mice.

Involvement of prefrontal AMPA receptors in encounter stimulation-induced hyperactivity in isolation-reared mice.

We recently showed that social encounter stimulation induces hyperactivity in mice reared in social isolation from early life and this is associated with the transient activation of prefrontal dopaminergic and serotonergic systems. In the present study, we examined the effect of the α-amino-3-hydroxy-5-methyl-4-isoxazolepropionate (AMPA) receptor antagonist 2, 3-dioxo-6-nitro-1, 2, 3, 4-tetrahydrobenzo[f]quinoxaline-7-sulfonamide (NBQX) on encounter-induced behavioural and neurochemical changes to study the role of the receptor in abnormal behaviours in isolation-reared mice. The encounter to an intruder mouse induced hyperactivity with transient increases in prefrontal dopamine and serotonin levels in isolation-reared mice.

Role of social encounter-induced activation of prefrontal serotonergic systems in the abnormal behaviors of isolation-reared mice.

Isolation-reared male rodents show abnormal behaviors such as hyperlocomotion, aggressive behaviors, deficits of prepulse inhibition, and depression- and anxiety-like behaviors, but the neurochemical mechanism for the effects of psychological stress in these animals is not fully understood. This study examined the effects of social interactions between isolation-reared mice and intruder mice on brain monoaminergic systems. A cage was divided into two compartments by a mesh partition to prevent direct physical interactions.
