General Factors and Dental-Related Risk Factors for Postoperative Pneumonia or Infectious Complications: A Retrospective Study.

Numerous studies report that perioperative oral care decreases the frequency of postoperative pneumonia or infection. However, no studies have analyzed the specific impact of oral infection sources on the postoperative course, and the criteria for preoperative dental care differ among institutions. This study aimed to analyze the factors and dental conditions present in patients with postoperative pneumonia and infection.

Efficient cell transplantation combining injectable hydrogels with control release of growth factors.

Introduction: The objective of this study is to investigate the effect of gelatin microspheres incorporating growth factors on the therapeutic efficacy in cell transplantation. The strength of this study is to combine gelatin hydrogel microspheres incorporating basic fibroblast growth factor and platelet growth factor mixture (GM/GF) with bioabsorbable injectable hydrogels (iGel) for transplantation of adipose-derived stem cells (ASCs).

Methods: The rats ASCs suspended in various solutions were transplanted in masseter muscle.

Endoscopic soft palate augmentation using injectable materials in dogs to ameliorate velopharyngeal insufficiency.

Background: Velopharyngeal structure augmentation methods are used as alternatives to pharyngeal flap operations. Recently, we investigated the sites of velopharyngeal structure augmentation in dogs and reported that the most effective injection location is the soft palate. However, there have been no reports regarding the optimal materials for implantation or injection.

The Behaviors of the Levator Veli Palatine Muscle Between 2 Surgical Conditions in Dog: The Comparison of Furlow and Pushback Methods.

Objective: This study was conducted to compare the velopharyngeal function among the beagle dogs which the levator veli palatini (LVP) muscles construction has been experimentally changed.

Methods: Four groups of LVP muscle reconstruction were made (normal LVP, cut LVP, end-to-end sutured LVP, and overlapped-sutured LVP at the midline). Levator veli palatini contraction was induced by electrical stimulation or a hypercapnia condition to analyze the strength of the velopharyngeal closure using balloon with a blood pressure meter, and the electromyogram in those operated beagle dogs.

Evaluation of sites of velopharyngeal structure augmentation in dogs for improvement of velopharyngeal insufficiency.

Background: Velopharyngeal structure augmentation methods are used as alternatives to velopharyngeal plasty. Anatomic sites of implantation/injection vary widely due to a lack of standardized criteria. Here, we experimentally investigated optimal sites of velopharyngeal structure augmentation via saline injection in dogs as they naturally exhibit velopharyngeal insufficiency (VPI).

Evaluation of a pseudo-one-compartment model for phosphorus kinetics by later-phase dialysate collection during blood purification.

Purpose: Phosphorus removal is a major issue to assess for physicians engaging in hemodialysis. A pseudo-one-compartment model was reported as a novel model for phosphorus kinetics. We aimed to evaluate the adequacy of this model from the standpoint of the total mass of removed phosphorus during prolonged treatment.

Primary sarcoma of the right ventricle: surgical and adjuvant therapy.

We describe surgical and adjuvant therapeutic management of a right ventricular (RV) sarcoma and pulmonary artery occlusion. Echocardiographic evaluation of a 39-year-old man with exertional dyspnea revealed a tumor mass in the right ventricle, pulmonary trunk, and bilateral pulmonary arteries. The tumor was resected with concomitant pulmonary valvotomy, but the resection was incomplete.

Hexaaquazinc(II) dipicrate trihydrate.

In the crystal structure of the title compound, [Zn(H2O)6](C(6)H(2)N(3)O(7))2.3H2O, the zinc cation complexes and picrate anions are stacked separately, extending along the b axis. No picrate species ligate to the metal cation.

Hexaaquairon(II) dipicrate dihydrate.

In the crystal structure of the title compound, [Fe(H(2)O)(6)](C(6)H(2)N(3)O(7))(2).2H(2)O, the centrosymmetric cationic iron complexes and picrate anions form separate stacks extending along the b axis. No picrate species ligate to the metal cation.
