マンガに描かれる女性の体形と日本人若年女性のボディイメージ

日本のマンガの持つ内容の広さ、豊かさ、洗練性および画像表現の自由度は、読む者のボディイメージに強い影響を与える可能性がある。マンガにおける若年女性の体形の描かれ方に関して、ジャンル別(男性向け一女性向け、成人向け-子供向け)の体形の特徴、物語上の役割や人物の性格が体形に及ぼす影響、作者の性別と作品のジャンルの関係について検討した。描かれた身体像は、現代日本の若年女性の標準体形と比較して、若年女子短期大学生らの視点から評価した。男性向けのマンガではやや細いウェストと大きなヒップを持った若年女性が描かれているのに対して、女性向けのマンガではウェスト・ヒップ共に細い若年女性が描かれていた。作品中の若年女性の役割や性格と体形の関係では、女性誌において女性性や母性がいずれも細い身体像と結びつき、また依存性が太いウェストと結びついていた。男性向けのマンガを男性が画いている一方、女性向けのマンガは女性が画いていた。これらの結果から、マンガにおいては非現実的な「やせ理想像」が、女性読者を対象として、女性マンガ家により作られていることが示された

The “Okusuri Charm” movement in Japan: Prescription drug accessories emerging on X (Twitter)

Abstract Background In this digital age, social networks may offer an avenue for individuals to obtain drugs illicitly beyond the prescribed amount. Users on X (Twitter)® have ingeniously fabricated fashionable accessories that employ prescription drug sheets, termed “Okusuri Charm”. Methods This cross‐sectional study scrutinized the emerging “Okusuri Charm” trend, by searching the term in Japanese on X (Twitter)® and analyzing related posts. Results Alongside illegal prescription drug trading, individuals crafted accessories from drug sheets, particularly prescribed psychiatric drugs, and dealt with other users, leading to a growing trend this year. Conclusions A positive outlook toward this trend is the emergence of a new artistic movement, but a pessimistic viewpoint is the creators' misuse of prescription drugs, potentially fostering illegal drug dealings

Investigation of the Transport Pathways Associated with Enhanced Brain Delivery of Peptide Drugs by Intranasal Coadministration with Penetratin

We previously found that coadministering peptides and proteins with the cell-penetrating peptide L-penetratin intranasally significantly increased transport to the brain and enhanced pharmacological effects. The present study aimed to clarify the mechanisms of nose-to-brain drug delivery enhancement by L-penetratin coadministration. First, we compared the concentrations of Exendin-4 in plasma and brain after intranasal and subcutaneous administration and suggested that coadministration with L-penetratin facilitated the direct nose-to-brain transport of Exendin-4. Second, we demonstrated that L-penetratin did not stimulate the transport of Cy7-labeled Exendin-4 and insulin through the trigeminal nerves but shifted their distribution to the olfactory mucosal pathway. Third, we investigated the distribution of insulin into the deeper regions of the brain after delivery via the olfactory pathway and suggested that insulin had entered the olfactory bulb, bottom part of the brain, and perivascular space through the cerebrospinal fluid and had diffused throughout the brain. We further demonstrated that intranasally delivered insulin with L-penetratin specifically accumulated on the hippocampus neuronal cells. Thus, this study suggested that administrating peptide drugs intranasally with L-penetratin allows direct transport to the olfactory bulb, bottom part of the brain, and perivascular space of the cerebral artery. This technique also potentially allows targeting of specific brain areas
