In addition, the carpels of one TfPLE knockout mutant had the same morphological abnormalities as TfPLE knockdown transgenic plants. TfFAR knockdown genome-edited mutants had no morphological changes in their floral organs. These results clearly show that TfPLE and TfFAR cooperatively play important roles in the development of stamens and carpels. Simultaneous disruption of TfPLE and TfFAR functions caused a multi-petal phenotype, which is expected to be a highly valuable commercial floral trait in horticultural flowers.PURPOSE We report a 15-month follow-up case on a Chinese patient with Oguchi disease associated with the multiple evanescent white dot syndrome (MEWDS). METHODS The patient's clinical presentation and follow-up visits were documented via decimal best-corrected visual acuity, fundus photography, fundus autofluorescence (FAF) imaging, near-infrared FAF, spectral domain optical coherence tomography, Humphrey's visual fields, microperimetry, and multifocal electroretinography. We also performed whole exome sequencing for screening variation in the patient and her relatives. RESULTS The patient had typical clinical characteristic of Oguchi disease, including night blindness, the Mizuo-Nakamura phenomenon (a golden yellow discoloration of the fundus that disappears in the prolonged dark adaptation [DA]) and typical full-field electroretinogram changes (nearly undetected b-wave in 0.01 and 0.03 ERGs that can partially recover only after prolonged DA). Aside from Oguchi disease, the patient was also diagnosed with the MEWDS based on clinical detections, including suddenly reduced visual acuity, appeared white dots, blurred ellipsoid zone and disrupted interdigitation zone, enlarged blind spot, and reduced macular sensitivity. A series of investigations revealed that along with the 15-month follow-up after onset, the visual acuity enhanced, the numerous white dots disappeared, and the macular structure returned to normal. Moreover, the novel homozygous splicing alteration c.181 + 1G > A was identified in the SAG gene. CONCLUSIONS This work is the first long-term case study of a patient with Oguchi disease associated with the MEWDS. The recovery period of symptoms caused by the MEWDS was much longer than that in typical patients with MEWDS. Molecular genetics demonstrate that this is the first case of Oguchi disease caused by splicing alterations in the SAG gene.The higher the dietary fat intake is in men, the worse their bone strength. By contrast, in women, both low and high fat intakes have negative impacts on bone strength. Dietary fat intake may be a modifiable factor affecting bone health, but this needs to be reconfirmed in further studies. PURPOSE Despite the general belief that higher fat intake may be harmful for bone health, its impact on bone strength has not been thoroughly studied. METHODS We conducted a population-based cross-sectional study derived from the Korea National Health and Nutrition Examination Surveys, including 2590 participants. Composite indices of femoral neck strength, such as the compression strength index (CSI), bending strength index (BSI), and impact strength index (ISI), were generated by combining bone mineral density, weight, and height with the femoral axis length and width. Nutritional status was assessed using a 24-h dietary recall questionnaire. RESULTS Dietary fat intake (% energy from fat intake/total energy intake × 100) er than the 24-h dietary recall method employed in this study.Density functional molecular orbital calculations are used to show the existence of two non-cubic isomeric structures of cubane and nitrated cubane. The isomers are shown to have no imaginary frequencies and are thus at a minimum on the potential energy surface. The calculations indicate the isomers are slightly more stable than the cubic structures.PURPOSE Nonfunctional pituitary adenomas (NFPAs) in pediatric and adolescent age are extremely rare. This study aimed to report a series of 14 pediatric and adolescent NFPAs to assist in its clinical management. METHODS A total of 14 consecutive patients pathologically diagnosed with NFPAs (age ≤ 20 years) were retrospectively examined, and the clinical data were analyzed. KP457 RESULTS NFPA is uncommon in pediatric and adolescent patients (0.4%). The most common clinical symptoms were a headache (6/14, 42.9%) and visual loss (4/14, 28.6%). Ten patients (71.4%) had preoperative hypopituitarism. All patients were diagnosed with macroadenoma including 8 (57.1%) invasive tumors, and the average tumor diameter was 2.8 cm. All patients underwent transsphenoidal surgery, and a near-total resection was achieved in nine (64.3%) patients. Postoperative visual acuity improved in three patients (75%). The results of immunohistochemistry showed 6 silent plurihormonal adenomas (42.9%), 3 null cell adenomas (21.4%), 3 silent lactotroph adenomas (21.4%), 1 silent gonadotroph adenoma (7.1%) and 1 silent corticotroph adenoma (7.1%). The mean follow-up was 54.8 months, and five patients had tumor recurrence. Tumors with Ki-67 ≧ 2% (28.6%) showed higher recurrence rate than those with lower index (P = 0.001). Two patients received secondary surgery and radiation for recurrent tumors suffered from panhypopituitarism. CONCLUSION Pediatric and adolescent NFPA is clinically rare, and shows potential invasiveness. The silent plurihormonal adenoma is the most frequent phenotype. Transsphenoidal surgery is as safe and effective as in adults. However, individualized care and teamwork of neurosurgeons, pediatricians, endocrinologists, and radiation oncologists are important, especially for recurrent diseases.PURPOSE Disc herniations are usually treated by decompression of the spinal nerves via a partial nucleotomy. As a consequence of reduced disc height (DH), reduced intradiscal pressure (IDP) and increased range of motion (ROM), accelerated degeneration may occur. Nucleus replacement implants are intended to restore those values, but are associated with the risk of extrusion. METHODS In six fresh frozen lumbar spinal segments (L2-3/L3-4/L4-5/L5-S1, age median 64.5 years (57-72), Pfirrmann grade 2-3), a prolapse was provoked through a box defect (6 × 10 mm) in the annulus. The herniated nucleus material was removed and replaced by a novel collagen-based nucleus implant. An annulus closure device sealed the defect. ROM, neutral zone (NZ) and IDP were measured in the (1) intact and (2) defect state, (3) postoperatively and (4) after cyclic loading (n = 100,000 cycles) applying pure moments (± 7.5 Nm) in flexion-extension, lateral bending and axial rotation. Additionally, the change in DH was determined. Extrusion of implants or nucleus material was evaluated macroscopically.
