Structure-activity relationship of volatile compounds that induce defense-related genes in maize seedlings.

Volatile organic compounds mediate plant-to-plant communication, and plants receiving volatile cues can acquire greater defenses against attackers. It has been expected that volatiles are received by factors that eventually lead to the induction of defense-related gene expression; however, the nature of these factors remain unclear. Structure-activity relationship analysis of gene expression induction by volatiles should provide insights into the nature of these factors.

Addition of a Buccinator Musculomucosal Flap Improves Surgical Outcomes of Conventional two-Flap Palatoplasty: A Comparative Study.

Objective: The surgical outcomes of novel two-flap palatoplasty adding a buccinator musculomucosal flap were compared with those of conventional two-flap palatoplasty to clarify the effects of lengthening the nasal mucosa of the soft palate using a BMMF in cleft lip and palate or cleft palate cases.

Design: Retrospective, comparative study.

Setting: Tertiary, cleft team.

The Palatal Fistula Closure Using Buccal Fat Graft After Palatoplasty for Cleft Palate: Two Case Reports.

Fistula recurrence is high after secondary follow-up operation to close the fistula after primary palatal surgery. Therefore, preventing fistula recurrence is important. Here, we describe the technique of closing palatal fistula after palatal surgery with a buccal fat graft in 2 cases.

A Foxtail-Shaped Vermilion Flap to Reconstruct the Medial Tubercle in Asymmetric Bilateral Cleft Lip With Contralateral Lesser Form Defect.

Objective: There have been few reports addressing asymmetric bilateral cleft lip repair with contralateral lesser form defects. Two studies have described the thin medial tubercle as the most common remaining labial deformity. In this study, we aimed to evaluate the use of a foxtail-shaped vermilion flap to reconstruct the median tubercle in primary repair.

Oronasal Transfixion Suture to Prevent Uplifted Nasal Floor Deformity in Cleft Lip and Palate Patients: A 5-Year Follow-Up.

Objective: In unilateral cleft lip and palate, the reconstructed nasal floor is sometimes uplifted regardless of the reconstructive method used. We used a 5-0 absorbable anchoring suture, the oronasal transfixion suture (ONT suture), to fasten the reconstructed nasal floor to the orbicularis oris muscle to prevent this deformity. This study was performed to evaluate the effects of the ONT suture.

Safety and efficacy of noncardiac surgical procedures in the management of patients with trisomy 13: A single institution-based detailed clinical observation.

Intensive treatment including surgery for patients with trisomy 13 (T13) remains controversial. This study aimed to evaluate the safety and efficacy of noncardiac surgical intervention for T13 patients. Medical records of patients with karyotypically confirmed T13 treated in the neonatal intensive care unit in Nagano Children's Hospital from January 2000 to October 2016 were retrospectively reviewed, and data from patients who underwent noncardiac surgery were analyzed.

Preoperative Treatment With Pazopanib in a Case of Chemotherapy-Resistant Infantile Fibrosarcoma.

Clinical and radiological diagnosis of infantile fibrosarcoma (IFS) is challenging because of its similarity to vascular origin tumors. Treatment involves complete resection. Although chemotherapy may allow more conservative resection, treatment guidelines are not strictly defined.

A simple and safe technique for manipulation of retrosternal dissection in the nuss procedure.

Objective: The Nuss procedure has become the first choice for repairing the pectus excavatum because of the advantages of the technique including minimal invasiveness and short operative duration. Although this technique appears simple and easy, life-threatening complications during dissection such as intraoperative cardiac perforation have been reported. We developed a new approach for safer dissection of retrosternal space.

CASE REPORT Penetrating Injury of the Orbit by a Needlefish.

Objective: We present a very rare case of penetrating injury into the orbit by a needlefish. The patient underwent extirpation twice at another hospital.

Methods: We performed foreign body removal from a right subbrow incision under general anesthesia.

Usefulness of infrared thermal imaging camera for screening of postoperative surgical site infection after the nuss procedure.

Introduction and Objective. The Nuss procedure is widely used in the treatment of pectus excavatum worldwide. Postoperative pectus bar infection is one of the most serious complications associated with this procedure.

A ringed fascia lata graft without peritendinous areolar tissue encircling the levator veli palatini and superior pharyngeal constrictor muscles gradually shrinks to reduce velopharyngeal incompetence, functioning as an intravelar palatal lift.

Introduction: We have previously reported that fascia lata grafts with peritendinous areolar tissue used to treat severe congenital blepharoptosis gradually shrink within 6 weeks postoperatively and maintain long-term shrinkage of 15.5% on average. Accordingly, it seemed possible that a fascia lata graft without peritendinous areolar tissue would shrink more than the one with peritendinous areolar tissue in a clinical setting.

Lateral vermilion border transposition flap to correct vermilion deformities with unilateral or bilateral cleft lip.

Previously, bilateral lateral vermilion border transposition flaps were reported to correct whistling lip deformity in patients with cleft lip. This study examined the long-term outcome in these patients and modified the procedure. Here, the use of this procedure is reported in 69 cleft lip patients.

Cell bodies of the trigeminal proprioceptive neurons that transmit reflex contraction of the levator muscle are located in the mesencephalic trigeminal nucleus in rats.

Since the levator and frontalis muscles lack interior muscle spindles despite being antigravity mixed muscles to involuntarily sustain eyelid opening and eyebrow lifting, this study has proposed a hypothetical mechanism to compensate for this anatomical defect. The voluntary contraction of fast-twitch fibres of the levator muscle stretches the mechanoreceptors in Müller's muscle to evoke proprioception, which continuously induces reflex contraction of slow-twitch fibres of the levator and frontalis muscles. This study confirmed the presence of cell bodies of the trigeminal proprioceptive neurons that transmit reflex contraction of the levator and frontalis muscles.

The practical procedure of tumescent technique in burn surgery for excision of burn eschar.

The tumescent technique, which involves injection of large volumes of dilute epinephrine solution into subcutaneous fat, has been shown to markedly increase the safety of liposuction surgery, which is associated with risks of blood loss. The authors use this technique during burn surgery and developed a practical method of determining the amount of solution injected. The authors have applied the tumescent technique consisting of subeschar infiltration of dilute epinephrine (1 mg/L) in thermoneutral (37 degrees C) saline.

A new technique for removing the pectus bar used in the Nuss procedure.

Background/purpose: The Nuss procedure involves elevation of the sternum using a pectus bar, which is subsequently removed after approximately 3 years. When removing the bar, the tip of 1 end of the bar is exposed, and then the body is changed to the lateral recumbent position to remove the bar along the body surface. However, changing body positions in a sterile manner is often difficult.

Implication of differences in the incidence of orbital emphysema in ethmoidal and maxillary sinus fractures.

This study investigated the incidence of orbital emphysema in patients with fractures of the ethmoidal cells or maxillary sinus. We noted that mucosal destruction is essential for orbital emphysema to occur. Computed tomographic examination and intraoperative studies of 58 patients with orbital bone fracture were performed with the patients divided into 2 groups according to the location of the fracture lines.
