To investigate whether high-intensity interval training (HIIT) and continuous moderate-intensity training (CMT) have different impacts on exercise performance and cardiac function and to determine the influence of these exercise protocols on modulating basal autophagy in the cardiac muscle of rats. Rats were assigned to three groups: sedentary control (SC), CMT, and HIIT. Total exercise volume and mean intensity were matched between the two protocols. After a 10-week training program, rats were evaluated for exercise performance, including exercise tolerance and grip strength...

Background/Aims: To investigate the efficacy of intravitreal aflibercept as rescue therapy for post-radiation cystoid macular edema (CME) resistant to prior treatment with intravitreal bevacizumab (IVB). Methods: Retrospective, interventional, case-controlled series. Eyes with persistent post-radiation CME were treated with intravitreal aflibercept (2 mg/0.05 mL). Central macular thickness (CMT) and visual acuity were compared to a matched control group treated with only IVB at 1 year...

Tumor-associated macrophages (TAMs) are an important component of leukocyte infiltration in tumors. TAMs can be classified into M1 and M2 phenotypes. In the present study, the expression of CD204, an M2-polarized macrophage receptor, was investigated by immunohistochemistry in the area surrounding TAMs in 101 cases of canine mammary gland tumor (CMT). We examined the relationship between M2-polarized TAMs and malignancy, histological subtype, histological grade, molecular subtype, hormone receptor (HR) status, and clinical obesity indices...

Charcot-Marie-Tooth (CMT) disease is the most common inherited peripheral neuropathy characterized by progressive distal muscle weakness and atrophy with decreased or absent tendon reflexes. Mutations in LRSAM1 have been identified to cause CMT disease type 2P. We report a novel LRSAM1 mutation c.2021-2024del (p.E674VfsX11) in a Chinese autosomal dominant CMT disease type 2 family. The phenotype was characterized by late onset and mild sensory impairment. Electrophysiological findings showed normal or mildly to moderately reduced motor and sensory nerve conduction velocities in lower and upper limb nerves...

HSPB3 gene encodes a small heat-shock protein 27-like protein which has a high sequence homology with HSPB1. A mutation in the HSPB3 was reported as the putative underlying cause of distal hereditary motor neuropathy 2C (dHMN2C) in 2010. We identified a heterozygous mutation (c.352T>C, p.Tyr118His) in the HSPB3 from a Charcot-Marie-Tooth disease type 2 (CMT2) family by the method of targeted next generation sequencing. The mutation was located in the well conserved alpha-crystalline domain, and several in silico predictions indicated a pathogenic effect of the mutation...

Purpose: Tranexamic acid (TXA) is a widely used antifibrinolytic agent that can also cause a decrease in vascular permeability. We hypothesized that TXA could improve macular edema (ME) that is caused by an increase in retinal vascular permeability. The aim of this study is to evaluate the efficacy of oral TXA for ME associated with retinal vein occlusion (RVO) or diabetic ME (DME). Patients and methods: Oral TXA (1,500 mg daily for 2 weeks) was administered to patients with persistent ME secondary to RVO (7 eyes) and DME (7 eyes)...

BACKGROUND: SH3TC2, PMP2, and BSCL2 genes are related to autosomal recessive (AR) Charcot-Marie-Tooth (CMT) disease type 1, autosomal dominant (AD)-CMT1, and AD-CMT2, respectively. Pathogenic variants in these three genes were not well documented in Chinese CMT patients. Therefore, this study aims to detect SH3TC2, PMP2, and BSCL2 pathogenic variants in a cohort of 315 unrelated Chinese CMT families. METHODS: A total of 315 probands from 315 unrelated Chinese CMT families were recruited from the Department of Neurology of Third Xiangya Hospital and Xiangya Hospital...

This work targets a remarkable quasi-distributed temperature sensor based on an apodized fiber Bragg grating. To achieve this, the mathematical formula for a proposed apodization function is carried out and tested. Then, an optimization parametric process required to achieve the remarkable accuracy that is based on coupled mode theory (CMT) is done. A detailed investigation for the side lobe analysis, which is a primary judgment factor, especially in quasi-distributed configuration, is investigated. A comparison between elite selection of apodization profiles (extracted from related literatures) and the proposed modified-Nuttal profile is carried out covering reflectivity peak, full width half maximum (FWHM), and side lobe analysis...

SH3TC2, known as the causative gene of autosomal recessive demyelinating Charcot-Marie-Tooth type 4C (CMT4C), was also found linked to a mild mononeuropathy of the median nerve with an autosomal dominant inheritance pattern. Using DNA microarray, Illumina MiSeq, and Ion proton, we carried out gene panel sequencing among 1483 Japanese CMT patients, containing 397 patients with demyelinating CMT. From seven patients with demyelinating CMT, we identified eight recessive variants in the SH3TC2 gene, consisting of five novel (pathogenic/likely pathogenic) and three reported variants...

OBJECTIVE: To perform a cross-sectional study to determine whether plasma neurofilament light chain (NfL) concentration is elevated in patients with Charcot-Marie-Tooth disease (CMT) and if it correlates with disease severity. METHODS: Blood samples were collected from 75 patients with CMT and 67 age-matched healthy controls over a 1-year period. Disease severity was measured using the Rasch modified CMT Examination and neuropathy scores. Plasma NfL concentration was measured using an in-house-developed Simoa assay...

AIM: To assess the two-year outcome of intravitreal ziv-aflibercept (IVZ) in eyes with macular diseases. METHODS: Consecutive subjects with various macular diseases that received six or more of 0.05 mL IVZ (1.25 mg) injections with at least 1 year follow-up were included. Outcome measures were best-corrected visual acuity (BCVA) (logarithm of the minimum angle of resolution) and central macular thickness (CMT) on spectral domain optical coherence tomography...

PurposeTo analyze the long-term efficacy of 577 nm sub-threshold micropulse yellow laser (SMYL) in the treatment of chronic central serous chorioretinopathy (CCSC) and to evaluate the anatomic outcome, visual results and safety profile of the treatment.Patients and methodsThis prospective study assessed 39 eyes of 39 patients with non-resolving CCSC lasting more than three months. All eyes were treated by using 577 nm SMYL system with 5% duty cycle (DC) and each patients was monitored monthly. The main outcome measures were best-corrected visual acuity (BCVA), contrast sensitivity (CS) and subretinal fluid (SRF) height, central macular thickness (CMT), central macular volume (CMV), total macular volume (TMV), and subfoveal choroidal thickness (SFCT) measured by spectral domain optical coherence tomography (SD-OCT)...

In hereditary neuropathies, next-generation sequencing techniques are producing a vast number of candidate gene mutations that need to be verified or excluded by careful genotype-phenotype correlation analysis. In most cases, clinical acumen is still important but needs to be combined with data from nerve conduction studies and, in some cases, from nerve biopsy examinations. Indeed, characteristic clinical, electrophysiological, and sometimes pathological features may be suggestive of a particular subtype of Charcot-Marie-Tooth (CMT) disease...

Background: Charcot-Marie-Tooth (CMT) disease is a hereditary neuropathy associated with impaired walking capacity. Some patients are too weak in the lower extremity muscles to walk at gravity with sufficient intensity or duration to gain benefit. Aim: The aim was to investigate the effect of aerobic anti-gravity exercise in weak patients with CMT 1A and X. Methods: Five adult patients performed moderate-intensity aerobic anti-gravity exercise 3/week for 10 weeks...
