Non-clinical pharmacokinetic profiles of rovatirelin,an orally available thyrotropin-releasing hormone analogue

1. The non-clinical pharmacokinetic profiles of rovatirelin, a novel thyrotropin-releasing hormone (TRH) analogue, were investigated in vivo and in vitro.

2. Rovatirelin orally administered to rats and dogs was rapidly absorbed and bioavailability was estimated to be 7.3 and 41.3%, respectively. The extent of plasma protein binding of rovatirelin in rats, dogs, and humans was low in all species (～15%). The permeability of rovatirelin from blood to brain (permeability-surface area) ranged from 1.04?±?0.14 to 1.29?±?0.28?μL/min/g in rats, and rovatirelin was stable in rat plasma and brain homogenates.

3. The metabolite pattern was qualitatively similar in vitro and in vivo. In animals, rovatirelin aminopentanoic acid (rovatirelin-acid), rovatirelin aminopentanone (rovatirelin-ketone), rovatirelin pyrrolidine (4S)-hydroxy (rovatirelin-OH), (thiazoylalanyl)methylpyrrolidine (TAMP), 3-(4-thiazoyl)-l-alanine (TA), and unknown metabolites were observed. In human hepatocytes, TAMP was mainly formed and no unique human metabolite was observed.

4. The radioactivity from administered [¹⁴C]rovatirelin was predominantly excreted in faeces in rats and dogs, and almost all radioactivity was recovered 168?h after administration. Absorption, brain penetration, and stability of rovatirelin in the brain were greater than for taltirelin.

5. Thus, orally administered rovatirelin is a potentially improved treatment for spinocerebellar degeneration compared with taltirelin.     

Simultaneous measurement of patient dose and distribution of indoor scattered radiation during digital breast tomosynthesis

Introduction

Breast cancer incidence increases from the age of 30 years. As this age range coincides with that in which women usually pursue pregnancy, undergoing medical examinations for conditions such as breast cancer is a concern, especially when pregnancy is uncertain during the first eight weeks. Moreover, in this age range, breast often exhibits a high density, thus compromising diagnosis. For such density, digital breast tomosynthesis (DBT) provides a more accurate diagnosis than 2D mammography given its higher sensitivity and specificity. However, radiation exposure increases during DBT, and it should be determined.

School health promotion in South‐East Asia by Japan and partners

School health promotion in South‐East Asia has developed rapidly in recent years, and Japan has been one of the significant contributors to the reinforcement of school health promotion in the region. Starting from the Hashimoto Initiative on global parasite control, Japan advocated for international partnerships with several agencies for the development of school health programs in South‐East Asia. Through a strengthened collaboration with international organizations, countries such as the Lao PDR, Cambodia, the Philippines, and Thailand have created and implemented school health programs on nutrition, sanitation, and deworming, among others. In addition to school health program formulation and implementation, the expanded network in South‐East Asia led to more capable school health personnel, with many workers in the education and health sectors benefitting from the training programs jointly held by collaborating organizations.
