Phosphite Reduces the Predation Impact of on Cyanobacterial Culture.

Contamination by the predatory zooplankton is one of the major threats that causes catastrophic damage to commercial-scale microalgal cultivation. However, knowledge of how to manage predator contamination is limited. Previously, we established a phosphite (Pt)-based culture system by engineering , which exerted a competitive growth advantage against microbial contaminants that compete with phosphate source.

[Medical team's struggle with financial abuse in the corresponding -Limitation of the adult guardianship system: A case report].

Upon diagnosis of dementia, a 93-year-old woman was unable to manage her finances. Her nephew illegally spent her money, which was considered as financial abuse.The public office forcibly admitted her to our hospital as a legal measure.

Synthetic Phosphorus Metabolic Pathway for Biosafety and Contamination Management of Cyanobacterial Cultivation.

Recent progress in genetic engineering and synthetic biology have greatly expanded the production capabilities of cyanobacteria, but concerns regarding biosafety issues and the risk of contamination of cultures in outdoor culture conditions remain to be resolved. With this dual goal in mind, we applied the recently established biological containment strategy based on phosphite (HPO, Pt) dependency to the model cyanobacterium Synechococcus elongatus PCC 7942 ( Syn 7942). Pt assimilation capability was conferred on Syn 7942 by the introduction of Pt dehydrogenase (PtxD) and hypophosphite transporter (HtxBCDE) genes that allow the uptake of Pt, but not phosphate (HPO, Pi).

Effect of urine pH changed by dietary intervention on uric acid clearance mechanism of pH-dependent excretion of urinary uric acid.

Background: The finding reported in a previous paper - alkalization of urine facilitates uric acid excretion - is contradictory to what one might expect to occur: because food materials for the alkalization of urine contain fewer purine bodies than those for acidification, less uric acid in alkaline urine should have been excreted than in acid urine. To make clear what component of uric acid excretion mechanisms is responsible for this unexpected finding, we simultaneously collected data for the concentration of both creatinine and uric acid in serum as well as in urine, in order to calculate both uric acid and creatinine clearances.

Methods: Within the framework of the Japanese government's health promotion program, we made recipes which consisted of protein-rich and less vegetable-fruit food materials for H + -load (acidic diet) and others composed of less protein and more vegetable-fruit rich food materials (alkaline diet).

Complex genomic rearrangement in the SOX9 5' region in a patient with Pierre Robin sequence and hypoplastic left scapula.

Pierre Robin sequence (PRS) can occur as a component of campomelic dysplasia (CD) and acampomelic CD (ACD) caused by dysfunction or dysregulation of SOX9, although it can also take place as an isolated form. Recently, genomic alterations in the far upstream and the far downstream region of SOX9 have been identified in patients with isolated PRS. Here, we report on a male patient with PRS and a heterozygous genomic rearrangement in the 5' region of SOX9.

Effect of urine pH on uric acid excretion by manipulating food materials.

A potential utilization of dietary intervention for reducing hyperuricemia was tested by managing food materials. Within the framework of the Japanese Government's health promotion program, we made recipes that consisted of more protein-rich and less vegetable/fruit-rich materials for the acidic diet and others composed of less protein-rich and more vegetable/fruit-rich materials for the alkaline diet. We have shown that urine alkalization facilitates uric acid excretion.

Urine alkalization facilitates uric acid excretion.

Background: Increase in the incidence of hyperuricemia associated with gout as well as hypertension, renal diseases and cardiovascular diseases has been a public health concern. We examined the possibility of facilitated excretion of uric acid by change in urine pH by managing food materials.

Methods: Within the framework of the Japanese government's health promotion program, we made recipes which consist of protein-rich and less vegetable-fruit food materials for H+-load (acid diet) and others composed of less protein but vegetable-fruit rich food materials (alkali diet).

Long term follow-up of atrioventricular valve function after repair of atrioventricular septal defect.

To elucidate the factors which are associated with early and late operative results of atrioventricular septal defects, 102 consecutive patients who underwent reparative operation of atrioventricular septal defects (AVSD) in our institution since 1968 were studied. Our operative technique was basically the same through this period. That is the two patch method in its complete form (the so-called Shirotani's method) and preferential use of cleft closure supplemented with Kay-Reed-Wooler type annuloplasty.

[A case of giant vesical calculus after ileocystostomy].

A 52-year-old female, who had undergone nephrectomy and ileocystostomy for right-renal tuberculosis and contracted bladder 19 years earlier was seen with anemia and metabolic acidosis. Radiographic findings demonstrated that the patient suffered from a giant vesical calculus. Cystolithotomy was performed and the removed calculus weighed 460 g.

[Congenital anterior urethral diverticulum: report of a case].

A case of congenital urethral diverticulum is reported. A 6-month-old male was admitted with difficulty to urinate and swelling of the base of penile shaft. Anterior urethral diverticulum was demonstrated by means of retrograde urethrography.

[A clinical study on renal pelvic and ureteral tumors].

Thirty-seven cases of renal pelvic and ureteral tumors treated at our hospitals between January, 1975 and December, 1985 were reviewed. There were 15 renal pelvic tumors, 19 primary ureteral tumors and 3 ureteropelvic tumors. There were 26 males and 11 females and their average age was 62.

[Retrograde nephrostomy for percutaneous nephrolithotomy].

Between June, 1985 and November, 1986, 25 patients at our institute underwent retrograde nephrostomy placement to provide percutaneous access to the kidney for percutaneous nephrolithotomy (PNL) of renal or upper ureteral calculi. Overall, retrograde nephrostomy was successfully completed through the desired calyx in 80% of the patients and calculi were successfully removed by the subsequent PNL. There were 5 failures primarily due to wrong indication and inexperience with the technique.

[Evaluation of immunosuppressive acid protein in genitourinary malignant diseases].

Clinical significance of serum immunosuppressive acid protein (IAP) was evaluated on the basis of experience on 55 patients with genitourinary malignant disease and 49 control patients. Although the measurement of serum level of IAP is not good enough to diagnose early stage of cancer, patients with 800 micrograms/ml or more of serum IAP can be suspected to have malignant diseases. With the exception of prostatic cancer, both mean serum level and positive rate of IAP were higher in patients with high stage of disease than in those with low stage.
