Objective: To investigate the relationships between depressive mood, bonding failure, and abusive parenting. Method: We distributed questionnaires to 1198 mothers attending a three-month postnatal health check-up in rural areas in Japan. The questionnaires assessed these three variables along with demographics. We evaluated the causal relationships by comparing different structural equation models to the data. Results: Although all the models fit the data well, the best Akaike Information Criterion was obtained from a model where both depressive mood and bonding failure predict abusive parenting, but depressive mood and bonding failure do not predict each other directly. The determinant coefficient of child abuse in the final model was 0.13. Discussion: We found depressive mood and bonding failure during postpartum period impacted negatively on mother’s parenting behaviour. Because only 13% of the variance of abusive parenting was explainable by this model, further study should be needed to identify other risk factors of child abuse. Similarly, midwives and public health nurse in community should pay attention to not only depression but also bonding failure to prevent child abuse.

Retinal ischemia causes several vision-threatening diseases, including diabetic retinopathy, retinal artery occlusion, and retinal vein occlusion. Intracellular adenosine triphosphate（ATP） depletion and subsequent induced endoplasmic reticulum（ER） stress are proposed to be the underlying mechanisms of ischemic retinal cell death. Recently, we found that a naphthalene derivative can inhibit ATPase activity of valosin-containing protein, universally expressed within various types of cells, including retinal neural cells, with strong cytoprotective activity. Based on the chemical structure, we developed novel valosin-containing protein modulators, Kyoto University Substances（KUSs）, that not only inhibit intracellular ATP depletion, but also ameliorate ER stress. Suppressing ER stress by KUSs is associated with neural cell survival in animal models of several neurodegenerative diseases, such as glaucoma and retinal degeneration. Given that a major pathology of ischemic retinal diseases, other than intracellular ATP depletion, is ER stress-induced cell death, KUSs may provide a novel strategy for cell protection in ischemic conditions. Hence, we investigated the efficacy of KUS121 in a rat model of retinal ischemic injury. Intravitreal injections of KUS121, which is clinically preferable route of drug administration in retinal diseases, significantly suppressed inner retinal thinning and retinal cell death, and maintained visual functions. Valosin-containing protein modulation by KUS is a promising novel therapeutic strategy for ischemic retinal diseases.

In glaucoma,a leading cause of blindness,retinal ganglion cells are progressively *** pressure reduction is the only established treatment for glaucoma(Collaborative Normal-Tension Glaucoma Study Group,1998;Vass et al.,2007).However,in some cases,visual field loss progresses despite sufficiently reduced intraocular pressure(Collaborative Normal-Tension Glaucoma Study Group,1998;Killer and Pircher,2018).While intraocular pressure and age are known risk factors for glaucoma(Ernest et al.,2013),the underlying mechanisms of glaucoma progression are not fully understood.

Biogas purification via water scrubbing produces effluent containing dissolved CH4, H2S,and CO2, which should be removed to reduce greenhouse gas emissions and increase its potential for water regeneration. In this study, a reactor built with air supplies at the top and bottom was utilized for the treatment of biogas purification effluent through biological oxidation and physical stripping processes. Up to 98% of CH4 was removed through biological treatment at a hydraulic retention time of 2 hr and an upper airflow rate of 2.02 L/day. Additionally, a minimum CH4 concentration of 0.04% with no trace of H2S gas was detected in the off gas. Meanwhile, a white precipitate was captured on the carrier showing the formation of sulfur. According to the developed mathematical model, an upper airflow rate of greater than 2.02 L/day showed a small deterioration in CH4 removal performance after reaching the maximum value, whereas a 50 L/day bottom airflow rate was required to strip the CO2 efficiently and raise the effluent p H from 5.64 to 7.3. Microbiological analysis confirmed the presence of type 1 methanotroph communities dominated by Methylobacter and Methylocaldum. However, bacterial communities promoting sulfide oxidation were dominated by Hyphomicrobium.
