RESUMEN

Bud sports in fruit crops often result in new cultivars with unique traits, such as distinct fruit size and color, compared to their parent plants. This study investigates the phenotypic differences and gene expression patterns in Tonewase and Ohtanenashi persimmon bud sports compared to those in their parent, Hiratanenashi, based on RNA-seq data. Tonewase is characterized by early maturation, whereas Ohtanenashi is noted for its larger fruit size. Despite the importance of these traits in determining fruit quality, their molecular bases in persimmons have been understudied. We compared transcriptome-level differences during fruit development between the bud sport samples and their original cultivar. Comprehensive transcriptome analyses identified 15,814 differentially expressed genes and 26 modules via weighted gene co-expression network analysis. Certain modules exhibited unique expression patterns specific to the different cultivars during fruit development, likely contributing to the phenotypic differences observed. Specifically, M11, M16, M22, and M23 were uniquely expressed in Tonewase, whereas M13 and M24 showed distinct patterns in Ohtanenashi. By focusing on genes with distinct expression profiles, we aimed to uncover the genetic basis of cultivar-specific traits. Our findings suggest that changes in the expression of genes associated with ethylene and cell wall pathways may drive Tonewase's earlier maturation, whereas genes related to the cell cycle within the M24 module appear crucial for Ohtanenashi's larger fruit size. Additionally, ethylene and transcription factor genes within this module may contribute to the increased fruit size observed. This study elucidates the differences in transcriptomic changes during fruit development between the two bud sport samples and their original cultivar, enhancing our understanding of the genetic determinants influencing fruit size and maturation.

RESUMEN

This study addresses the propagation challenges faced by 'Shine Muscat', a newly introduced premium grapevine cultivar in South Korea, where multiple viral infections pose considerable economic loss. The primary objective was to establish a robust in vitro propagation method for producing disease-free grapes and to identify effective plant growth regulators to facilitate large-scale mass cultivation. After experimentation, 2.0 µM 6-benzyladenine (BA) exhibited superior shoot formation in the Murashige and Skoog medium compared with kinetin and thidiazuron. Conversely, α-naphthaleneacetic acid (NAA) hindered shoot growth and induced callus formation, while indole-3-butyric acid (IBA) and indole-3-acetic acid (IAA) demonstrated favorable root formation, with IBA showing better results overall. Furthermore, inter simple sequence repeat analysis confirmed the genetic stability of in vitro-cultivated seedlings using 2.0 µM BA and 1.0 µM IBA, validating the suitability of the developed propagation method for generating disease-free 'Shine Muscat' grapes. These findings offer promising prospects for commercial grape cultivation, ensuring a consistent supply of healthy grapes in the market.

RESUMEN

Relapsing polychondritis (RP) is a rare disease which presents chondritis in multiple organs. Characteristic features include auricular chondritis, arthritis, nasal chondritis, ocular inflammation, respiratory tract involvement and audiovestibular damage. Fifty percent of cases of RP are associated with inner ear symptoms such as dizziness and hearing loss. We have recently encountered a case of RP in a 34-year-old man who had recurrent chondritis of both auricles and progressive bilateral profound sensorineural hearing loss; he had been treated many times with steroids, immunosuppressants, plasmapheresis treatments. We perfomed a successful cochlear implant surgery on the left ear of this patient. This raises the possibility of using cochlear implants in treating patients with immune-mediated inner ear disease as well as such RP patients.

RESUMEN

BACKGROUND: We evaluated synthetic polyurethane foam (SPF; Polyganics BV, Groningen, The Netherlands) as a packing material used after septoplasty compared with Merocel (Medtronic Xomed Surgical Products, Jacksonville, FL) in the aspects of clinical efficacy and the subjective severity of symptoms. METHODS: A prospective, randomized, single-blinded controlled study was performed in 64 patients who had undergone septoplasty. The patients were randomized to receive Merocel or SPF after septoplasty. Assessments of clinical efficacy on bleeding and pain were done and subjective symptoms related to packing materials were evaluated using questionnaires quantified by the visual analog scale. RESULTS: There was no difference in repacking or additional packing due to postoperative bleeding, bleeding and/or septal hematoma on the removal of packing, and the mucosal condition after packing removal during postoperative period between the Merocel and SPF groups. Bleeding and pain during packing removal was significantly lower in patients with SPF packing. Also, in the SPF group, patient's general satisfaction and willingness to reuse the material were higher compared with the Merocel group. CONCLUSION: SPF is as suitable as Merocel to be used after septoplasty with beneficial effects on bleeding and pain at packing removal.

RESUMEN

PURPOSE: In treating schwannoma patients, it is critical to determine the origin of the tumor to preserve nerve function. We evaluated the validity of preoperative imaging studies in distinguishing the neurological origin of the schwannomas of the head and neck, and the efficacy of intracapsular enucleation in preserving nerve function. MATERIALS AND METHODS: In 7 cases of schwannomas in the head and neck region, we predicted whether the tumor originated from the vagus nerve or the cervical sympathetic chain through imaging studies including computed tomography (CT) and magnetic resonance imaging (MRI). All patients were performed intracapsular enucleation, and the function of the vagus nerve and the sympathetic nerve was evaluated preoperatively and postoperatively. RESULTS: Preoperative imaging studies showed 6 cases where the tumor was located between the carotid artery and the internal jugular vein, and 1 case where the tumor was located posteriorly, displacing the carotid artery and the internal jugular vein anteriorly. At the time of operation, we confirmed schwannoma originating from the vagus nerve on the first 6 cases, and schwannoma originating from the sympathetic nervous system on the last case. All patients went through successful intracapsular enucleation, and of the seven schwannoma cases, 6 patients maintained normal postoperative neurological function (85.7%). CONCLUSION: Preoperative imaging studies offer valuable information regarding the location and origination of the tumor, and intracapsular enucleation helped us to preserve the nerve function.

RESUMEN

EGb 761, extracted from Ginkgo biloba leaves, has been proven to induce caspase-3-dependent apoptosis in oral cavity cancer cells. Since EGb 761 is a composition of various components, it is important to identify which components are responsible for its anticancer effects to reduce the total dosage and to avoid toxicity. Therefore, the study aimed to determine the effective compounds of EGb 761 that induce apoptosis in oral cavity cancer cells and to identify whether caspase-3 was involved in apoptosis of oral cancer cells by EGb 761 components. The results of cell proliferation assays on oral cavity cancer cells showed that kaempferol and quercetin significantly inhibited cellular proliferation at a concentration of 40 microM. Flow cytometry showed that the antiproliferative effects of each component were due to increased apoptosis. Kaempferol and quercetin induced apoptosis in various oral cancer cell lines (SCC-1483, SCC-25 and SCC-QLL1) and showed cleavage of poly (ADP-ribose) polymerase (PARP). Caspase-3 activity assay revealed that induction of apoptosis by kaempferol and quercetin was caspase-3-dependent. In conclusion, the results suggest that kaempferol and quercetin, two components of EGb 761, effectively induce caspase-3-dependent apoptosis of oral cavity cancer cells and can be considered as possible anti-oral cavity cancer agents.

RESUMEN

According to our previous study, Ginkgo biloba extract (GBE) suppresses IL-1beta-induced MUC5AC gene expression in NCI-H292 cells via the ERK and p38 MAPK pathways. This study sought to identify which ingredients of GBE suppress IL-1beta-induced MUC5AC gene expression in NCI-H292 cells and to examine which MAPKs are related to MUC5AC gene suppression for each ingredient. After the cells were pretreated with each ingredient and treated with IL-1beta (10 ng/mL), MUC5AC mRNA expression was determined by RT-PCR and real-time PCR. The results showed that kaempferol (KP) and quercetin (QC) suppressed MUC5AC mRNA expression in a dose-dependent manner, both with significant inhibition starting from 40 microm (equal concentration to about a twelfth or thirteenth dose of GBE). MAPK proteins were determined by western blot analysis after pretreatment with KP, QC and GBE. All three suppressed the phosphorylation of ERK and p38 kinases. In conclusion, the data suggested that KP and QC, essential ingredients in GBE, may overcome the dose problem of GBE and play a valuable role, clinically, in controlling mucin hypersecretion in airway inflammation.

RESUMEN

An anterior clinoid mucocele, known to be extremely rare, can lead to visual complications due to its proximity to the optic nerve. We report a patient who developed visual disturbance due to an anterior clinoid mucocele. Interestingly, the anterior clinoid mucocele coexisted with a sphenoid sinus mucocele. When an anterior clinoid mucocele coexists with a sphenoid sinus mucocele, more deliberate diagnostic and therapeutic approaches must be considered according to our first experience.
