Purpose: This study aimed to investigate the relationship between linea alba width and unclosed pediatric umbilical hernias.
Methods: A retrospective chart review was conducted on patients with pediatric umbilical hernias persisting beyond the age of 2, from April 2014 to March 2021. Additionally, data from children who underwent computed tomography (CT) for other conditions or injuries, such as diarrhea or traffic accidents, were collected from April 2010 to March 2022.
Pharyngeal electrical stimulation (PES) applies electrical stimulation to pharyngeal mucosa (PhM) and represents a useful approach to improve swallowing function in patients with dysphagia. To determine the optimal PES modality to treat dysphagia, the mechanism underlying the effects of PES on swallowing function must be elucidated. In this study, we evaluated how PES and electrical stimulation of the superior laryngeal nerve (SLN) modulate the initiation of swallowing in anesthetized rats.

Anticholinergic medication causes impaired swallowing with hyposalivation. However, the underlying mechanisms by which these drugs modulate the swallowing reflex remain unclear. This study investigated the effects of the muscarinic acetylcholine receptor (mAChR) nonspecific antagonist atropine on the initiation of swallowing.

Weakness of the mucosal free margin is common in secondary cleft lip deformities. However, the incidence is rarely reported after a long-term follow-up. We evaluated the evolution of patient mucosal free margin after primary repair and until the end of growth.

Nasal reconstruction in very elderly patients is challenging. We attempted subtotal nasal reconstruction with an expanded double forehead flap and autologous costal cartilage support in a 91-year-old woman presenting with subtotal nasal defects after sebaceous carcinoma resection. Only small parts of the bilateral alae and the columella base remained after resection, and the frontal area of the septum was also resected.

The aim of the surgical treatment of thumb polydactyly is to reconstruct a functional and aesthetically pleasing thumb. Hypoplasia of joint components and abnormal tendon alignment lead to unpleasing results with angular deformity of the reconstructed thumb.

Enzymatic synthesis of β-hydroxy-α-amino acids has attracted considerable interest as a selective, sustainable, and environmentally benign process. In this study, we identified a novel amino acid hydroxylase, AEP14369, from Sulfobacillus thermotolerans Y0017, which is included in a previously constructed CAS-like superfamily protein library, to widen the variety of amino acid hydroxylases.

Objective: The present study aimed to examine the current state of oral hypofunction among outpatients at the university hospital.
Background: Although several investigations have described the safety, utility, and precision of magnetic resonance lymphography (MRL) as a preoperative examination for lymphaticovenular anastomosis (LVA), it is unclear how much MRL assistance impacts LVA results. The present study aimed to clarify the outcome of MRL-assisted LVA for leg lymphedema using body water measurements obtained by bioelectrical impedance analysis.
Methods: The water reductive effect of MRL-assisted LVA in female secondary leg lymphedema patients was compared with that of non-MRL-assisted controls in this retrospective study.
Examining the coordination of respiration and swallowing is important for elucidating the mechanisms underlying these functions and assessing how respiration is linked to swallowing impairment in dysphagic patients. In this study, we assessed the coordination of respiration and swallowing to clarify how voluntary swallowing is coordinated with respiration and how mastication modulates the coordination of respiration and swallowing in healthy humans. Twenty-one healthy volunteers participated in three experiments.

Methods: Eighteen patients with leg lymphedema were recruited for this prospective study.
This case-control retrospective study focused on the extracellular water ratio (%ECW) of lymphedemic limbs measured by bioelectrical impedance analysis (BIA) as a possible indicator of the development and severity of unilateral and bilateral leg lymphedema. BIA was used to evaluate changes in %ECW due to lymphedema in female patients with unilateral secondary leg lymphedema and in healthy controls. Receiver operating characteristic (ROC) analysis was employed to assess the diagnostic ability of %ECW to distinguish leg lymphedema patients from controls.

We used a pulp tissue reduction method to avoid the need for external bleeding techniques and blood transfusions.
Methods: We examined 18 fingers in cases of Ishikawa's subzone II, III, and IV amputation that were replanted with artery-only anastomosis and pulp tissue reduction from April 2003 to March 2018.
Background: We previously examined the water reductive effect of lymphaticovenular anastomosis (LVA) using bioelectrical impedance analysis (BIA) measurement on lower-limb lymphedema and revealed mean water volume reduction and edema reduction rate by leg LVA to be 0.86 L and 45.1%, respectively.

This study evaluated the association between pre-operative parameters concerning the extent of the injury and post-operative diplopia, using multivariate analysis. A retrospective computed tomography analysis and chart review was performed for patients with punched out orbital floor fracture, who underwent operations during the period from April 2011 to March 2018.

Methods: In this retrospective visual and chart review, patients younger than 3 months with umbilical hernias who initially visited Ina Central Hospital from April 2011 to March 2017 and were followed until they started to walk (at the age of 1 year) were evaluated. The umbilici of the patients at the age of 1 year were classified into two types based on their appearance: concave and protuberant umbilici.
An 86-year-old woman had a pacemaker implanted into a subfascial pocket. After four months, the generator became exposed, and the pacemaker was removed. She exhibited a lack of prepectoral tissue.

While they are widely used in optogenetics to optically control neuronal activity, rhodopsins that function with longer-wavelength light are highly demanded because of their low phototoxicity and high tissue penetration. Here, we achieve a 40-nm red-shift in the absorption wavelength of a sodium-pump rhodopsin (KR2) by altering dipole moment of residues around the retinal chromophore (KR2 P219T/S254A) without impairing its ion-transport activity.
