The aim of this study was to develop the dynamic model of lower limb using static and dynamic reflex properties of flexion reflex. Identification of torque response associated with hip angle and angular velocity was tested in 6 subjects with chronic SCI. Each subject placed in a supine position and lower leg was fixed with the knee at 155°±12 and the ankle at 126°±14. The hip was aligned with the axis of the Biodex motor in order to impose hip movements to the leg. A train of 10 stimulus pulses (50mA, 1ms) as reference pulse were applied at 200Hz to the skin of the medial arch to trigger flexion reflex reflexes. From this experiment, we identified the torque response as linear function of hip angle and angular velocity. In order to simulate the lower limb of spinal cord injured patients for functional electrical stimulation, we developed two dimensional dynamic model with three segments, thigh, shank and foot. Influences of stimulation parameters such as amplitude, frequency and duration time of pulse train were investigated with Taguchi method to obtain best results.

Objectives: Recent studies have introduced middle ear volume(MEV) as a novel determinant of perforation-induced conductive hearing loss(CHL) in a mechanism driven by trans-tympanic membrane pressure differences. The primary aims of this preliminary report are to: 1) correlate CHL with perforation size; 2) describe the relationship between CHL and MEV; and 3) compare CHL across a range of cholesteatoma ***: A retrospective pilot study was performed in 31 subjects with audiometry indicative of conductive hearing loss, temporal bone CT scans,and no prior middle ear surgery. Perforation size and MEV were analyzed with respect to CHL in a cohort of 10 perforated ears with no cholesteatoma. CHLs were compared in 3 groups defined by extent of cholesteatoma ***: Ears with large and small perforations showed mean ABG values of 32.0 ± 15.7 dB and 16.0 ± 16.4 dB, respectively. A direct relationship was observed between MEV and CHL for ears with large perforations across all frequencies, whereas this relationship for small perforations was frequency-dependent. Finally, a statistically significant increase in CHL was found across ears with increasing cholesteatoma involvement at 1000 Hz(X^2(2) = 9.786, p = 0.008),2000 Hz(x^2(2) = 8.455, p = 0.015),and 4000 Hz(x^2(2)= 8.253, p = 0.016).Conclusions: These pilot data suggest that greater perforation-induced conductive hearing losses may be associated with larger perforation sizes and cholesteatoma. The correlation between MEV and CHL may require additional study.

Disagreement in middle ear volume estimation between tympanometry and three-dimensional volume reconstruction in the context of tympanic membrane perforation

Introduction: Middle ear volume(MEV) is a clinically relevant parameter across middle ear diseases. MEV values between these techniques have never before been tested for agreement in ears with perforated tympanic membranes(TMs).Methods: Middle ears were identified from 36 patients ranging 18-89 years of age with TM perforations who underwent tympanometry and temporal bone computed tomography(CT) between 2005 and 2015. MEVs calculated by both tympanometry and three-dimensional volume reconstruction(3DVR) were analyzed for agreement using Bland Altman plots. The differences between tympanometric and 3DVR MEV values for each given middle ear were characterized across MEV quartiles(1= smallest; 4= largest) and across increasing states of middle ear disease using Kruskale Wallis and Wilcoxon testing with Bonferroni ***: Bland Altman plots demonstrated significant disagreement between MEV measurement techniques. Differences between tympanometric(T) and 3DVR MEV values were significantly greater with increasing average(i.e.(Tt3DVR)/2)) MEV per linear regression(p < 0.0001). Significance was demonstrated between fourth and first average MEV quartiles(p= 0.0024), fourth and second quartiles(p= 0.0024), third and first quartiles(p= 0.0048), and third and second quartiles(p= 0.048). Absolute MEV difference was not significantly different across varying states of middle ear disease(p= 0.44).Conclusion: Statistically and clinically significant disagreement was demonstrated between tympanometric and 3DVR MEV values. Studies that vary in MEV estimation techniques may be expected to demonstrate significantly different results. These preliminary results suggest that clinicians should endeavor to seek further confirmation when interpreting high tympanometric MEV values.

We identified torque response of flexion reflex associated with hip angle and angular velocity in 6 subjects with chronic SCI and developed two dimensional dynamic model with three segments, thigh, shank and foot. Influences of stimulation parameters such as amplitude, frequency and duration time of pulse train for producing swing motion of lower limb were investigated with response surface method to obtain optimal solutions. The initial hip flexion velocity (F-value > 19.0) and knee flexion velocity (F-value > 9.0) were clearly significant, while the initial hip angle was indistinguishable from the estimated amount of error. When the limb motion was simulated with initial hip and knee flexion velocity, the stimulation amplitude was increased 53%, the frequency was decreased 37% and the duration time was decreased 33% with respect to no initial condition. © 2005 IEEE.

“Sng” is a Taiwanese term describing a distinct state of soreness. Accumulating evidence indicates that sng is a specific somatosensory modality, independent of pain, with distinct receptors and transduction pathways. In recent years, variations in its presentation across different medical specialties have highlighted the need for a standardized definition of sng-related terminology. To address this, the Taiwan Sng Society established a multidisciplinary Sng Taxonomy Task Force, comprising 32 experts in both clinical and basic sciences related to sng. Here we summarize the discussions and expert consensus from the Task Force. A total of 16 sng-related terminology was defined. The first edition of sng terminology aims to establish a clear, standardized framework for the clinical practice and research of sng. © 2025 Formosan medical Association

Massive usage of antibiotics harms the environment through animals’ excrement and squeezes open-wellbeing issues. Enrofloxacin (EF), an antimicrobial agent, treats bacterial diseases and infections in cattle, poultry and exotic animals and exhibits harmful side effects. The present work proposed a sensitive and rapid electrochemical scaffold based on the Cu-Ni bimetallic-organic framework (Cu-Ni-MOF) for the detection of harmful EF in real-time applications. The Cu-Ni-MOF was synthesized through solvothermal approach with the support of a multifunctional organic ligand, 4,4-biphenyldicarboxylicacid and characterized through various analytical tools. The electrochemical sensor for EF detection was constructed by drop-casting the Cu-Ni-MOF on a glassy carbon electrode and the fabricated sensor exhibited higher catalytic activity when compared to the parental counterparts by exhibiting 1.7-fold higher current for EF oxidation. Further, the fabricated sensor is highly active in the linear range response of 200 nM–2 mM with a limit of detection of 15.17 nM and sensitivity of 638.71 µA mM cm −2 under optimized environments. The higher electrocatalytic activity of the Cu-Ni-MOF electrode synergistically stems from the strong interaction between Cu 2+ of the MOF and pyridone and carboxylate moieties of the EF and facile electron transition facilitated by Ni 2+ . The practicability of the sensor was evaluated in milk, egg and river water samples and the obtained results were validated with Liquid Chromatography-Mass Spectrometric technique. Furthermore, the prepared catalyst was utilized for the photochemical decontamination of EF and the present Cu-Ni-MOF catalyst delivered excellent photocatalytic activity in the decontamination of EF under visible light at ambient temperature.
