Discrete Two-Degree-of-Freedom Control for Hemodynamic Optimization: Circulatory Simulation Study with Baroreflex Variability.

The baroreflex mechanism supports hemodynamic stability, but its function is often impaired under conditions such as heart failure. In drug therapy for heart failure, the causal mechanisms determining hemodynamics become more complicated due to combined pharmacological and uncertain baroreflex effects. The purpose of this paper is to propose a cli- nically feasible hemodynamic control system that compensates for individual variability caused by the baroreflex mechanism.

Facile chemical modification of solid alkaline lignin and chitosan via nucleophilic substitution with organohalides in the vapor phase.

The reaction of solid alkaline lignin and chitosan with vapors of organohalides, namely allyl bromide and epichlorohydrin, is presented as a sustainable alternative to conventional solvent-based techniques for modifying these model nucleophilic biopolymers. This approach, which does not necessitate any catalysts or pre-treatments, exploits the inherent nucleophilicity of specific functional groups present in the biopolymers, such as sodium carboxylates, sodium phenolates, and amines, facilitating nucleophilic substitution reactions directly with the vapors of the modifying agents. Fuming with epichlorohydrin introduced 1,3-glyceryl bridges in both alkaline lignin and chitosan, resulting in their extensive crosslinking.

Searching for More Effective Food Baits for Tephritid Fruit Flies (Diptera: Tephritidae): Performance of Newly Developed Vial-Lures Relative to Torula Yeast Borax.

Food-baited traps are an important part of early detection programs for invasive tephritid fruit fly species, as they are attractive to both sexes of all targeted species. Torula yeast borax (TYB) mixture is a standard food bait, but its longevity is limited (1-2 weeks). Synthetic food-based lures have been developed, including ammonium acetate, putrescine, and trimethylamine.

The Association Between Myasthenia Gravis and Higher Extrathymic Cancer Risk.

Background: Myasthenia gravis (MG) is strongly associated with thymic tumors, but whether it is also associated with extrathymic cancers is debatable or whether MG can be considered a paraneoplastic disorder for extrathymic cancers.

Methods: This is a retrospective analysis of the MG cohort for 23 years' time (January 2000 to May 2023), extracting cancer rates with clinical, electrophysiological, and biochemical cancer associations and the effect of chronic medications.

Results: We identified 436 patients with MG and 3924 controls.

Integration of Through-Sapphire Substrate Machining with Superconducting Quantum Processors.

A sapphire machining process integrated with intermediate-scale quantum processors is demonstrated. The process allows through-substrate electrical connections, necessary for low-frequency mode-mitigation, as well as signal-routing, which are vital as quantum computers scale in qubit number, and thus dimension. High-coherence qubits are required to build fault-tolerant quantum computers and so material choices are an important consideration when developing a qubit technology platform.

Distinguishing Chronic Inflammatory Demyelinating Polyneuropathy From Mimic Disorders: The Role of Statistical Modeling.

Background And Aims: Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is difficult to distinguish from mimicking disorders, with misdiagnosis resulting in IVIG overutilization. We evaluate a clinical-electrophysiological model to facilitate CIDP versus mimic neuropathy prediction.

Methods: Using the European Academy of Neurology/Peripheral Nerve Society (EAN/PNS) 2021 CIDP guidelines we derived 26 clinical and 144 nerve conduction variables.

First Reported Case of Hemoglobin Graz in the United States: Implications for Misleading Hemoglobin A Results.

Routine serum studies in a female patient with sustained prediabetic glycated hemoglobin A (HbA) levels, controlled on metformin, yielded an unexpected finding: an elevated HbA value of ≥14.9% (≥139 mmol/mol) (normal reference range, <5.7% to <39 mmol/mol).

Perceptual learning and neural correlates of virtual navigation in subjective cognitive decline: A pilot study.

Spatial navigation deficits in age-related diseases involve brain changes affecting spatial memory and verbal cognition. Studies in blind and blindfolded individuals show that multisensory training can induce neuroplasticity through visual cortex recruitment. This proof-of-concept study introduces a digital navigation training protocol, integrating egocentric and allocentric strategies with multisensory stimulation and visual masking to enhance spatial cognition and brain connectivity in 17 individuals (mean age 57.

Predicting chronic post-traumatic head and neck pain: the role of bedside parameters.

Facile preparation of solid gelatin foams by a water-lean batch foaming process.

Existing polystyrenic and polyolefinic packaging foams are non-biodegradable, and persist in the environment for hundreds of years. Gelatin foams are an interesting alternative, given their biodegradability, biocompatibility, solution-based processability, low cost, and non-toxicity. However, current methods for preparing gelatin foams, such as freeze-drying, microfluidic foaming, and batch foaming, are not suitable for high-volume production.

Long term survival and outcomes in patients with paraneoplastic neurologic syndromes.

Objective: It is unknown whether delay in diagnosis affects morbidity reportedly in paraneoplastic syndromes (PNS). We aimed to explore various aspects of PNS, including prevalence, clinical characteristics, diagnostic criteria, and treatment outcomes.

Methods: We studied n-PNS diagnosis between 2016 to 2023, and included only patients with positive onconeural antibodies, who developed cancer, and exhibited a recognizable PNS phenotype.

Addition of ammonium acetate to torula yeast borax and its effect on captures of three species of economically important fruit flies (Diptera: Tephritidae).

Many countries operate continuous trapping programs to detect invasive fruit flies (Diptera: Tephritidae) that threaten fruit and vegetable production. Food-based attractants are an important component of these programs, as they are generalized baits that attract both sexes of all target species. However, food baits are considered weak attractants, and the development of improved food attractants would benefit surveillance efforts.

Optimizing Anti-Myelin-Associated Glycoprotein and IgM-Gammopathy Testing for Neuropathy Treatment Evaluation.

Background And Objectives: Patients with typical anti-myelin-associated glycoprotein (anti-MAG) neuropathy have IgM-gammopathy, mimic distal chronic inflammatory demyelinating polyradiculoneuropathy (CIDP), and are treatment resistant. Anti-MAG patients go unrecognized when IgM-gammopathy is undetected or with atypical phenotypes. We investigated an optimal anti-MAG titration cutoff for excluding CIDP and the impact of IgM-gammopathy detection on neuropathy treatment evaluation without anti-MAG antibodies.

Patient Perception of Mental Effort in Voice Therapy.

Objective: One challenge in voice therapy is that mastering new vocal techniques is inherently cognitively effortful. While effort is critical for learning, it can also lead to frustration and reduced patient engagement. The purpose of this study was to investigate the relationship between patient-perception of voice handicap and mental effort in voice therapy, and to determine if different therapy approaches and stimuli elicit different perceptions of mental effort.
