Difference between voluntary control and conscious balance processing during quiet standing.

The mechanism by which postural threat induced by standing at a high height causes a decrease in the amplitude and an increase in the frequency of postural sway might involve voluntary control (VC) to avoid swaying, rather than conscious balance processing, in which postural threat directs conscious balance processing. This study aimed to clarify the differences between VC and conscious balance processing during quiet standing. Twenty-seven healthy young adults were instructed to stand with their feet placed together and keep their eyes open.

Changes in Standing Postural Control Ability in a Case of Spinocerebellar Ataxia Type 31 With Physical Therapy Focusing on the Center of Gravity Sway Variables and Lower Leg Muscle Activity.

Spinocerebellar degeneration (SCD) is a progressive disease characterized by cerebellar ataxia or the posterior spinal cord. Among these, spinocerebellar ataxia type 31 (SCA31) is genetically more common in the Japanese population and is characterized by pure ataxia, resulting in severe disturbances in postural balance, with common falls. Therefore, rehabilitation is important to improve postural balance.

Identification and verification of communicating accessory bile duct associated with a biliary circuit by modified and dynamic intraoperative cholangiography during laparoscopic cholecystectomy.

Communicating accessory bile duct (CABD) is a rare anatomical anomaly of the bile duct and forms a biliary circuit. It is difficult to identify during laparoscopic cholecystectomy (LC) without the use of intraoperative cholangiography (IOC). A modified IOC, in which tube insertion was performed through the infundibulum of the gallbladder, was evaluated dynamically.

Effects of postural-control training with different sensory reweightings in a patient with body lateropulsion: a single-subject design study.

Introduction: Body lateropulsion (BL) is an active lateral tilt of the body during standing or walking that is thought to be affected by a lesion of the vestibulospinal tract (VST) and the subjective visual vertical (SVV) tilt. Interventions for BL have not been established.

Objective: We examined the effects of postural-control training with different sensory reweighting on standing postural control in a patient with BL.

Robot-assisted total remnant gastrectomy for interposed jejunal pouch dysfunction 25 years after proximal gastrectomy for gastric cancer: A case report.

Proximal gastrectomy (PG) in combination with jejunal pouch interposition is a technique aimed at improving the postoperative dietary outcomes; however, some cases are reported to require surgical intervention owing to difficulty of food intake caused by pouch dysfunction. Herein, we present a case of robot-assisted surgery for interposed jejunal pouch (IJP) dysfunction in a 79-year-old male, occurring 25 years after the initial PG for gastric cancer. The patient had chronic anorexia for 2 years and was treated with medications and dietary guidance; however, 3 months prior to admission his quality of life had reduced, owing to worsening symptoms.

Navigation by modified and dynamic intraoperative cholangiography during laparoscopic subtotal cholecystectomy for difficult gallbladder.

We used modified and dynamic intraoperative cholangiography (IOC) navigation during laparoscopic subtotal cholecystectomy for difficult gallbladders. We have defined an IOC that does not open the cystic duct as a modified IOC. Modified IOC methods include the percutaneous transhepatic gallbladder drainage (PTGBD) tube method, the infundibulum puncture method, and the infundibulum cannulation method.

Relationships between changes in lateral vestibulospinal tract excitability and postural control by dynamic balance intervention in healthy individuals: A preliminary study.

Introduction: We conducted dynamic balance or static intervention on healthy young adults to examine the changes in lateral vestibulospinal tract (LVST) excitability and postural control that ensued following dynamic balance intervention and to investigate the correlation between these changes.

Methods: Twenty-eight healthy young adults were randomly assigned to either the dynamic balance group or the control group. They performed either a dynamic balance or static intervention for 10 trials of 30 s each and were assessed for head jerks during the intervention to confirm adaptation to the intervention.

Stone removal by percutaneous papillary balloon dilatation for cystic duct and bile duct stones after cholecystectomy and distal gastrectomy with Roux-en-Y gastrojejunostomy.

A 71-year-old woman was referred to our department for abdominal pain. She was diagnosed with acute obstructive cholangitis due to cystic duct and bile duct stones after cholecystectomy and Roux-en-Y gastrojejunostomy. Two years ago, the patient underwent endoscopic and laparoscopic treatment for cystic duct and bile duct stones, however, the stones remained.

Characteristics of Japanese patients with non-dialysis-dependent chronic kidney disease initiating treatment for anemia: a retrospective real-world database study.

Objective: Anemia is a common complication of chronic kidney disease (CKD). The aim of this study was to evaluate hemoglobin levels at the initiation of erythropoiesis stimulating agent (ESA) therapy in patients with non-dialysis-dependent CKD (NDD-CKD) and anemia using a large-scale administrative database in Japan.

Methods: The longitudinal data of adult patients who initiated ESA therapy between April 2008 and December 2018 were extracted from a hospital-based administrative database.

Substituent Effects at the 5,10-Positions of Dianilinotripyrrins on Their Dimerization Themodynamics.

Control of the association behavior by molecular design is one of the most essential benefits in artificial supramolecular systems. 1,14-Dianilinotripyrrin has recently emerged as a novel conjugated molecule which forms a double helix in non-polar solvents with the aid of multiple interstrand hydrogen bonding interactions. In this work, we investigated the substituent effects at the 5,10-positions of tripyrrin on their association thermodynamics.

Methods: Of the 22 preschools within Unnan City, Shimane Prefecture, Japan, 21 (95.

Palladium-catalyzed dehydrogenative C-H cyclization for isoindolinone synthesis.

In this paper Pd-catalyzed intramolecular dehydrogenative C(sp)-H amidation for the synthesis of isoindolinones is described. This method features the use of a Pd/C catalyst and the addition of a stoichiometric amount of oxidant is not necessary. A mechanistic study suggested the possible formation of H gas during the reaction.

Modified and dynamic intraoperativecholangiography during laparoscopic cholecystectomy in two patients with aberrant right posterior hepatic duct.

Aberrant right posterior hepatic duct (ARPHD) is one of the anatomical anomalies of the bile duct. It is a risk factor for bile duct injury during laparoscopic cholecystectomy (LC). ARPHD can be diagnosed before surgery by magnetic resonance cholangiopancreatography or drip infusion cholangiographic-computed tomography.

Movement Coordination during Forward and Backward Rope Jumping: A Relative Phase Study.

Rope jumping is a popular training method in athletic programs, fitness, and physical education. Forward and backward rope jumping has been used for evaluating athlete's performance. Both of these two jumps require coordination in the upper and lower limbs.

Characteristics of postural control during fixed light-touch and interpersonal light-touch contact and the involvement of interpersonal postural coordination.

Haptic feedback by light touch with a fingertip influences the postural control of the human body by postural orientation. Postural control might therefore differ depending on the characteristics of the contacting object. The main experimental targets of contact have been a fixed object (fixed light touch: FLT) and an individual (interpersonal light touch: ILT), but the postural control characteristics of FLT and ILT have not been directly compared within the same study.

The Motor Engram of Functional Connectivity Generated by Acute Whole-Body Dynamic Balance Training.

Purpose: Whole-body dynamic balance is necessary for both athletic activities and activities of daily living. This study aimed to investigate the effect of acute dynamic balance training on neural networks.

Methods: We evaluated resting-state functional connectivity (rs-FC), white matter fiber density, fiber-bundle cross-section, and gray matter volume in 28 healthy young adults (14 women) before and after 30 min of slackline training using a randomized, counterbalanced crossover design.

Development of the Peripheral Functionalization Chemistry of meso-Free Corroles.

In contrast to the extensive development of the meso-functionalization of porphyrins, that of corroles had rarely been explored until the development of practical synthetic methods for meso-free corroles in 2015. The ready availability of meso-free corroles opened up meso-functionalization chemistry of corroles, giving rise to successful synthesis of various meso-substituted corroles such as meso-halogen, meso-nitro, meso-amino, meso-oxo, and meso-iminocorroles as well as meso-meso-linked corrole dimers and corrole tapes. In some cases, 2NH corroles exist as stable or transient radical species.

Sarcoidosis-lymphoma syndrome with portal hypertension: diagnostic clues and approach.

Sarcoidosis-lymphoma syndrome associated with portal hypertension is very rare. A 68-year-old female presented with a 5 kg weight loss in 6 months. Soluble interleukin-2 receptor activity was increased and total platelet count was decreased.

Synthesis of 8,12-Dibromocorrole and Its Transformation to Antiaromatic 8,10-Fused Iminoisocorrole with a Polarized Resonance Contribution.

8,12-Dibromo-5,15-bis(pentafluorophenyl)corrole and its Ag(III) complex were prepared via intramolecular oxidative coupling of a 8,12-dibromobilane precursor. The Ag(III) complex was allowed for further transformation via Suzuki coupling reaction. Thus, 2-aminophenyl group was coupled at one of the β-positions, and subsequent demetalation followed by oxidation with MnO afforded 8,10-fused iminoisocorrole in good yields.

-Oxoisocorroles: Tunable Antiaromaticity by Metalation and Coordination of Lewis Acids as Well as Aromaticity Reversal in the Triplet Excited State.

The corrole derivative -oxoisocorrole has been theoretically predicted to be antiaromatic, despite its formally cross conjugated electronic system. In this study, this prediction has been experimentally proven by the facile preparation of -oxoisocorrole via the oxidation of a free corrole with MnO and its comprehensive characterization using NMR, UV/vis absorption, FT-IR, and transient-absorption spectroscopy, cyclic voltammetry, and X-ray diffraction analysis. Furthermore, the free base -oxoisocorrole was metalated by treatment with Ni(acac), PdCl(PhCN), and Zn(OAc) to give the corresponding metal complexes.

Reliability and laterality of the soleus H-reflex following galvanic vestibular stimulation in healthy individuals.

The vestibulospinal tract (VST) plays an important role in the control of the ipsilateral antigravity muscles, and the balance of left and right VST excitability is important in human postural control. A method for measuring VST excitability is the application of galvanic vestibular stimulation (GVS) before tibial nerve stimulation that evokes the soleus H-reflex; the change rate of the H-reflex amplitude is then evaluated. Assessments of VST excitability and the left and right balance could be useful when determining the pathology for interventions in postural control impairments.
