Background And Purpose: Irritable bowel syndrome (IBS) is a common condition that is challenging to treat, and novel drugs are needed for this condition. Previously, a chronic vicarious social defeat stress (cVSDS) mouse model exhibits IBS-like symptoms. Also agonists of the opioid δ-receptor exert anti-stress effects in rodents with minimal adverse effects.

Tau pathology is a hallmark of several neurodegenerative diseases, including frontotemporal dementia and Alzheimer's disease. However, the sequence of events and the form of tau that confers toxicity are still unclear, due in large part to the lack of physiological models of tauopathy initiation and progression in which to test hypotheses. We have developed a series of targeted mice expressing frontotemporal-dementia-causing mutations in the humanized MAPT gene to investigate the earliest stages of tauopathy.

Arketamine alleviates cognitive impairments and demyelination in mice with postoperative cognitive dysfunction via TGF-β1 activation.

Prog Neuropsychopharmacol Biol Psychiatry

January 2025

Chiba University Center for Forensic Mental Health, Chiba 260-8670, Japan; Department of Anesthesiology, Pain and Perioperative Medicine, The First Affiliated Hospital of Zhengzhou University, Zhengzhou 450052, China. Electronic address:

Postoperative cognitive dysfunction (POCD) is characterized by a decline in cognitive functions, including memory, attention, and executive abilities, following surgery, with no effective therapeutic drugs currently available. Arketamine, the (R)-enantiomer of ketamine, has shown promise in mitigating cognitive deficits in animal models. In this study, we investigated whether arketamine could ameliorate cognitive deficits in a mouse model of POCD, with a focus on the role of transforming growth factor (TGF)-β1 in its effects.

Int J Clin Oncol

December 2024

Translational Research Support Office, Division of Drug and Diagnostic Development Promotion, Department for the Promotion of Drug and Diagnostic Development, National Cancer Center Hospital East, 6-5-1 Kashiwanoha, Kashiwa, Chiba, 277-8577, Japan.

Background: The implementation of cancer precision medicine in Japan is deeply intertwined with insurance reimbursement policies and requires case-by-case reviews by Molecular Tumor Boards (MTBs), which impose considerable operational burdens on healthcare facilities. The extensive preparation and review times required by MTBs hinder their ability to efficiently assess comprehensive genomic profiling (CGP) test results. Despite attempts to optimize MTB operations, significant challenges remain.

Chem Commun (Camb)

January 2025

Department of Life Science and Technology, Institute of Science Tokyo, Nagatsuta 4259, Midori-ku, Yokohama 226-8501, Japan.

Article Synopsis
  • Extracellular vesicles (EVs) from cancer cells can cause normal cells to grow uncontrollably, which might contribute to cancer spread.
  • Researchers created a device using nanowires that effectively removes these EVs without harming the cells.
  • By using this device, they were able to return normal growth to mammary gland cells that had been exposed to cancer cell-derived EVs.

Introduction: Increased muscle stiffness in the upper trapezius has been suggested to be associated with cervical myofascial pain and myofascial trigger points (MTrP). Recently, efforts have been made to objectively detect MTrP using ultrasound shear wave elastography (SWE). However, there is no consensus on the relationship between muscle stiffness assessed by SWE and MTrP.

Brain Res Bull

January 2025

Department of Anesthesiology, Pain and Perioperative Medicine, The first Affiliated Hospital of Zhengzhou University, Zhengzhou,  China; Chiba University Center for Forensic Mental Health, Chiba 260-8670, Japan. Electronic address:

Chronic pain is commonly recognized as a distressing symptom or a standalone disease, with over half of those affected experiencing cognitive impairment, which significantly impacts their quality of life. Despite a recent surge in literature on cognitive impairment associated with chronic pain, a comprehensive bibliometric analysis in this field has yet to be conducted. In this study, we performed a bibliometric analysis on this topic.

Isotopes unveil overestimation of nutrient-driven oxygen deficit in the tidal rivers of Pearl River Delta during the wet season.

Sci Total Environ

The Key Laboratory of Water and Air Pollution Control of Guangdong Province, South China Institute of Environmental Sciences, Ministry of Ecology and Environment, Guangzhou 510530, China; National Key Laboratory of Water Environment Simulation and Pollution Control, South China Institute of Environmental Science, Ministry of Ecology and Environment, Guangzhou 510535, China. Electronic address:

A low dissolved oxygen (DO) concentration in summer has been observed in river-estuary systems worldwide. Many studies have caused our stereotype that biochemical oxygen depletion was higher in summer than in winter; however, there was no direct evidence particularly in the tidal river with complex hydrological and biochemical processes. This study employed natural-abundance and labeled isotopes to quantify seasonal apportionment of biochemical oxygen depletion.

High molecular weight hyaluronic acid alleviates ovariectomy-induced bone loss in mice.

BMC Musculoskelet Disord

December 2024

Department of Orthopaedic Surgery, Graduate School of Medical and Dental Sciences, Tokyo Medical and Dental University (Institute of Science Tokyo), 1-5-45 Yushima Bunkyo-Ku, Tokyo, 113-8519, Japan.

Background: The rapid decline in ovarian function associated with menopause promotes osteoclast differentiation and increases bone resorption, disrupting of bone homeostasis and increasing the risk of osteoporosis. Hyaluronic acid (HA) is a polysaccharide ubiquitously present in the connective tissues. Recent reports indicate that high-molecular-weight HA (HMW-HA) promotes osteoblast proliferation, enhances alkaline phosphatase activity and mineral deposition, and promotes the expression of bone differentiation markers, such as Runx2 and osteocalcin.

3,4-Methylenedioxymethamphetamine (MDMA; Ecstasy) is a widely abused recreational drug that has also gained interest for potential clinical applications in mental health. With the growing recognition of gut microbiota's role in mental health, this study examined whether repeated oral MDMA administration could affect gut microbiota in the small intestine, cecum, and colon of male rats. Repeated oral MDMA administration (10 mg/kg/day for 14 days) caused significant changes in the gut microbiota across these regions, with distinct effects observed in each.

Although multiple studies suggest that ionizing radiation can induce bystander effects (radiation-induced bystander effect, RIBE) in cultured cell lines, it is still unclear whether RIBE is evolutionarily conserved in invertebrates. In this study, we investigated the frequency of cell death of unirradiated starfish (Patiria pectinifera) oocytes co-cultured with oocytes irradiated with X rays (0, 2 and 4 Gy). We observed increased frequencies of cell death determined by morphological abnormality and TUNEL-positive cells in unirradiated oocytes co-cultured with oocytes irradiated with 2 Gy or 4 Gy oocytes.
