Association of Intensive Morphine Treatment and Increased Stroke Incidence in Prostate Cancer Patients: A Population-based Nested Case-Control Study
Conclusions Intense morphine treatment may be associated with an increased stroke incidence in patients with malignancy, and the association is particularly significant for prostate cancer patients.

Effects of thalamic hemorrhagic lesions on explicit and implicit learning during the acquisition and retrieval phases in an animal model of central post-stroke pain.
Abstract Hemorrhagic stroke has many symptoms, including central pain, learning and memory impairments, motor deficits, language problems, emotional disturbances, and social maladjustment. Lesions of the ventral basal complex (VBC) of the thalamus elicit thermal and mechanical hyperalgesia, forming an animal model of central post-stroke pain (CPSP). However, no research has yet examined the involvement of learning and memory in CPSP using an animal model. The present study examined whether VBC lesions affect motor function, conditioned place preference (CPP; implicit memory), and spatial learning (explicit memory)...

Risk of type 2 diabetes mellitus in female breast cancer patients treated with morphine: a retrospective population-based time-dependent cohort study
A key element of the palliative care of cancer patients is the management of chronic pain [1]. Opioids continue to be a mainstay in the management of cancer pain in all treatment guidelines [2], and morphine is regarded as the “gold standard” [3–6]. Considered as broad-spectrum analgesics, opioids have multiple side effects and potential complications [7]. Our previous studies indicated that morphine treatment is associated with subdural hemorrhage [8], pulmonary embolism [9], and acute coronary syndrome [10] in cancer patients, as well as increased stroke incidence in prostate cancer patients [11].

Challenge to the Intestinal Mucosa During Sepsis
Conclusion The impact of sepsis on the gut is manifold, e.g., sepsis mediated alteration of the gut-blood barrier and increase in the intestinal permeability, which may correlate with the phenomena of bacterial translocation and lymphatic activation (“toxic-lymph”). Systemic consequences of sepsis are widespread and concern to the coagulative system, the microbiome as well as enzymes, such as pancreatic proteases, MMPs and IAPs. Nevertheless, the therapeutic approaches for modulating the mucosal immune system are still rarely effective in daily routine. Recent published studies showing that treatment with ...

Lysophosphatidic Acid Receptor Signaling Underlying Chronic Pain and Neuroprotective Mechanisms through Prothymosin α.
Abstract For my Ph.D. research topic, I isolated endogenous morphine-like analgesic dipeptide, kyotorphin, which mediates Met-enkephalin release, and discovered kyotorphin synthetase, a putative receptor and antagonist. Furthermore, I succeeded in purifying μ-opioid receptor and functional reconstitution with purified G proteins. After receiving my full professor position at Nagasaki University in 1996, I worked on two topics of research, molecular mechanisms of chronic pain through lysophosphatidic acid (LPA) and identification and characterization of neuroprotective protein, prothymosin α. In a series of studi...
