Parthenocarpy, the pollination-independent fruit set, can raise the productivity of the fruit set even under adverse factors during the reproductive phase. The application of plant hormones stimulates parthenocarpy, but artificial hormones incur extra financial and labour costs to farmers and can induce the formation of deformed fruit. This study examines the performance of parthenocarpic mutants having no transcription factors of and and that do not have the protein-coding gene, , in tomato (cv.

Tomato is one of vegetables crops that has the highest value in the world. Thus, researchers are continually improving the agronomical traits of tomato fruits. Auxins and gibberellins regulate plant growth and development.

Object: Chronic subdural hematomas (CSDHs) recur in 7 to 18% of cases. The present study was conducted to determine whether serum or lesion concentrations of coagulofibrinolytic and angiogenic factors, which have been reported to be potential markers of CSDH development, might predict such recurrences.

Methods: Sixty consecutive patients (mean age 71.

With the development of MRI and MRA, many unruptured aneurysms have been detected and treated. Nevertheless, not a few false-positive and false-negative cases are found. We investigate aneurysms that were suspected after screening MRA at the neurosurgical outpatient clinic and the features of aneurysms detected not with MRA but with DSA were studied.

We describe our experience with Sophy programmable valve shunts, compared with Codman-Hakim programmable shunts in cases with normal pressure hydrocephalus (NPH) after subarachnoid hemorrhage (SAH). A total of 147 consecutive patients underwent 204 shunt implantations (102 Sophy valves, 51 Codman-Hakim valves, 51 nonprogrammable valves). Of these, 23 Sophy and 25 Codman-Hakim valves respectively were implanted into patients with NPH after SAH.

Thallium-201 chloride single photon emission computed tomography ((201)TlCl SPECT) has been applied extensively for studies of human tumors. To assess which indices for (201)TlCl SPECT are most useful for diagnosing brain lesions, a total of 82 patients (98 images) with intracranial abnormalities were investigated. Seventy-six cases with abnormal (201)Tl uptake were evaluated in terms of six different (201)Tl uptake and retention indices: (1) average early (201)Tl uptake = Av.

A case of a patient with astrocytoma who showed somnolence and asterixis one month after tumour resection is presented. Although primidone had been prescribed preoperatively for five years and the same dose was maintained after the operation, the serum concentration of the primidone metabolite phenobarbital was elevated and she demonstrated hyperammonemic encephalopathy, which disappeared on withdrawal of the drug. A description of this seldom reported phenomenon during primidone therapy is given, with reference to valproate cases.
