Environmentally Benign Adsorption Materials for Removing Arsenic from Aquatic Environment  [PDF]
Katsutoshi Inoue, Hiroyuki Harada, Kedar Nath Ghimire, Biplob Kumar Biswas, Hidetaka Kawakita, Keisuke Ohto
Advances in Materials Physics and Chemistry (AMPC) , 2018, DOI: 10.4236/ampc.2018.81005
Abstract: Adsorptive removal of arsenic using adsorption gels prepared from orange and apple juice residues was reviewed by summarizing the authors’ previous papers. Orange and apple juice residues contain a large amount of pectin, partly methyl-esterified pectic acid, which exhibits high affinity for high-valent metal ions such as iron(III), rare earths(III) and zirconium(IV). Anionic species of arsenic(III, V) are effectively and selectively adsorbed on pectic acid gel via loading these high-valent metal ions. Raw orange juice residue was saponified using calcium hydroxide to improve the loading capacity for these metal ions. It was found that zirconium(IV) exhibits the most suitable adsorption behaviors for arsenic(III, V). Similar result was obtained also for apple juice residue. An actual sample of acid mine drainage from the Horobetsu mine which contained a high concentration of iron and low concentration of arsenic, was tested using the adsorption gel prepared from orange juice residue and the results were compared with those from the current treatment process based on coprecipitation with iron hydroxide. The new process using the above- mentioned adsorption gel was proposed for treatment of such acid mine drainage.
Effectiveness of Electroconvulsive Therapy for Depression and Cotard’s Syndrome in a Patient with Frontotemporal Lobe Dementia
Toshiyuki Kobayashi,Koju Inoue,Katsutoshi Shioda,Satoshi Kato
Case Reports in Psychiatry , 2012, DOI: 10.1155/2012/627460
Abstract: In the field of psychogeriatrics, the differential diagnosis of depression and dementia, as well as the treatment of depression and comorbid dementia, is an important issue. In this paper, the authors present the case of a 72-year-old woman with Cotard’s syndrome and frontotemporal dementia (FTD) who was admitted to a psychiatric hospital with delusions of negation accompanied by depressive symptoms. Pharmacotherapy over a 2-year hospitalization was unsuccessful, and she was subsequently transferred to our university hospital. A total of 18 sessions of electroconvulsive therapy released her from psychomotor inhibition, appetite loss, and Cotard’s delusions. The indication for electroconvulsive therapy in patients with dementia is discussed.

In this paper, the authors present the case of a 72-year-old woman with Cotard’s syndrome and frontotemporal dementia (FTD) who was admitted to a psychiatric hospital with delusions of negation accompanied by depressive symptoms. Pharmacotherapy over a 2-year hospitalization was unsuccessful, and she was subsequently transferred to our university hospital. A total of 18 sessions of electroconvulsive therapy released her from psychomotor inhibition, appetite loss, and Cotard’s delusions. The indication for electroconvulsive therapy in patients with dementia is discussed. 1. Introduction Depression and dementia are among the most common disorders seen in mental health clinical practice for elderly people with mental disorders. The conundrum is that both disorders sometimes coexist, can sometimes succeed each other, and hence can often confuse clinicians [1–3]. Even though we do not have sufficient clinical tools to cure dementia, depression is thought to be treatable. We can try to relieve the distress of patients with this comorbidity by at least treating the depression. However, elderly patients with depression often have somatic and/or psychiatric disease, an atypical clinical picture, and sensitivity to environmental or psychological factors [2] and are often resistant to pharmacotherapy or show adverse effects with antidepressants. In such cases, electroconvulsive therapy (ECT) can become an important option [1]. In this paper, we present a case of a senile patient with marked inhibition, appetite loss, and delusions similar to Cotard’s syndrome, who was almost bedridden for 2 years. She was diagnosed with frontotemporal dementia (FTD) with depression, but ECT released her from the depressive symptoms including inhibition that had led to her being bedridden. 2. Case Representation A female, ex-blue-collar worker, and housewife gradually lost her willingness to work sometime in the spring at the age of 72 years. Although she had been a hard worker busy caring for others, she started washing only her own and not her family’s dishes. She also started showing incomprehensible rigid behavior: when her husband was admitted to hospital, she doggedly kept to her daily routine of walking. She complained of loss of appetite and insomnia and was unwilling to go out and socialize. Her family took her to a neurologist, but neurological examination and brain computed tomography (CT) revealed
Biological Clogging of Sand Columns  [PDF]
Katsutoshi Seki
Open Journal of Soil Science (OJSS) , 2013, DOI: 10.4236/ojss.2013.33017
Abstract:

Increased microbial activity leads to biological clogging (or bioclogging), i.e., the pore space is clogged by microbes and saturated hydraulic conductivity of porous media decreases. A series of column experiments were carried out to study the bioclogging of sand columns. Hydraulic conductivity remained unchanged when a sterilizing agent was applied; however, it decreased when a glucose solution was applied. In most cases, bioclogging proceeded from the inlet of the solution; but, in some cases, it started from the bottom or outlet of the column. In this experiment, the reduction of hydraulic conductivity was better explained by microcolony models compared to biofilm models.

Leaching of phosphorus from incinerated sewage sludge ash by means of acid extraction followed by adsorption on orange waste gel

Abstract: Ashes from sewage sludge incineration have a high phosphorus content, approximately 8% (W/W), which indicates a potential resource of the limiting nutrient. Incineration of sewage sludge with subsequent recovery of phosphorus is a relatively new sludge treatment technique. In this article, the leaching of phosphorus by using sulfuric acid as well as hydrochloric acid by means of several batch experiments was presented. At the same time a selective recovery of phosphorus by adsorption was also discussed. The e ects of acid concentration, temperature and time on extraction were studied. The phosphorus leaching increased with the increase in acid concentration and temperature. Kinetic studies showed that the complete leaching of phosphorus took place in less than 4 h. Selective adsorption of phosphorus by using orange waste gel provided a hint for recovery of this natural resource, which eventually could meet the ever-increasing requirement for phosphorus. The overall results indicated that the incinerated sewage sludge ash can be treated with acid to e ciently recover phosphorus and thus can be considered a potentially renewable source of phosphorus.
The Origin And Migration Of Primordial Germ Cells In Sturgeons

Abstract: Primordial germ cells (PGCs) arise elsewhere in the embryo and migrate into developing gonadal ridges during embryonic development. In several model animals, formation and migration patterns of PGCs have been studied, and it is known that these patterns vary. Sturgeons (genus Acipenser) have great potential for comparative and evolutionary studies of development. Sturgeons belong to the super class Actinoptergii, and their developmental pattern is similar to that of amphibians, although their phylogenetic position is an out-group to teleost fishes. Here, we reveal an injection technique for sturgeon eggs allowing visualization of germplasm and PGCs. Using this technique, we demonstrate that the PGCs are generated at the vegetal pole of the egg and they migrate on the yolky cell mass toward the gonadal ridge. We also provide evidence showing that PGCs are specified by inheritance of maternally supplied germplasm. Furthermore, we demonstrate that the migratory mechanism is well-conserved between sturgeon and other remotely related teleosts, such as goldfish, by a single PGCs transplantation (SPT) assay. The mode of PGCs specification in sturgeon is similar to that of anurans, but the migration pattern resembles that of teleosts.

Abstract: AIM: To compare the outcome of surgical treatment of colorectal adenocarcinoma in elderly and younger patients.METHODS: The outcomes of 122 patients with colorectal adenocarcinoma who underwent surgical treatment between January 2004 and June 2009 were analyzed. The clinicopathological and blood biochemistry data of the younger group (< 75 years) and the elderly group (≥ 75 years) were compared.RESULTS: There were no significant differences between the two groups in operation time, intraoperative blood loss, hospital stay, time to resumption of oral intake, or morbidity. The elderly group had a significantly higher rate of hypertension and cardiovascular disease. The perioperative serum total protein and albumin levels were significantly lower in the elderly than in the younger group. The serum carcinoembryonic antigen level was lower in the elderly than in the younger group, and there was a significant decreasing trend after the operation in the elderly group.CONCLUSION: The short-term outcomes of surgical treatment in elderly patients with colorectal adenocarcinoma were acceptable. Surgical treatment in elderly patients was considered a selectively effective approach.
