Background To evaluate the feasibility and safety of a fast initiation of cooling to a target temperature of 35℃by means of transnasal cooling in patients with anterior circulation large vessel occlusion(LVO)undergoing endovascular thrombectomy(EVT).Methods Patients with an LVO onset of<24hour who had an indication for EVT were included in the *** cooling(RhinoChill)was initiated immediately after the patient was intubated for EVT and continued until an oesophageal target temperature of 35℃was *** was maintained with surface cooling for 6-hour postrecanalisation,followed by active rewarming(+0.2℃/hour).The primary outcome was defined as the time required to reach 35℃,while secondary outcomes comprised clinical,radiological and safety *** Twenty-two patients(median age,77 years)were included in the study(14 received additional thrombolysis,4 additional stenting of the proximal internal carotid artery).The median time intervals were 309min for last-seen-normal-to-groin,58min for door-to-cooling-initiation,65min for door-to-groin and 123min for *** target temperature of 35℃was reached within 30min(range 13–78min),corresponding to a cooling rate of 2.6℃/*** recanalisation,86%of the patients had a body temperature of≤35℃.The median National Institutes of Health Stroke Scale at admission was 15 and improved to 2 by day 7,and 68%of patients had a good outcome(modified Rankin Scale 0–2)at 3 *** complications included asymptomatic bradycardia(32%),pneumonia(18%)and asymptomatic haemorrhagic transformation(18%).Conclusion The combined application of hypothermia and thrombectomy was found to be feasible in sedated and ventilated *** events were comparable to those previously described for EVT in the absence of *** effect of this procedure will next be evaluated in the randomised COmbination of Targeted temperature management and Thrombectomy after acute Ischemic Stro

Fresnel Equations Derived Using a Non-Local Hidden-Variable Particle Theory

引用

Journal of Modern Physics 2024年第6期15卷 950-984页

作者： dirk J. Pons Department of Mechanical Engineering University of Canterbury Christchurch New Zealand

Problem: The Fresnel equations describe the proportions of reflected and transmitted light from a surface, and are conventionally derived from wave theory continuum mechanics. Particle-based derivations of the Fresnel equations appear not to exist. Approach: The objective of this work was to derive the basic optical laws from first principles from a particle basis. The particle model used was the Cordus theory, a type of non-local hidden-variable (NLHV) theory that predicts specific substructures to the photon and other particles. Findings: The theory explains the origin of the orthogonal electrostatic and magnetic fields, and re-derives the refraction and reflection laws including Snell’s law and critical angle, and the Fresnel equations for s and p-polarisation. These formulations are identical to those produced by electromagnetic wave theory. Contribution: The work provides a comprehensive derivation and physical explanation of the basic optical laws, which appears not to have previously been shown from a particle basis. Implications: The primary implications are for suggesting routes for the theoretical advancement of fundamental physics. The Cordus NLHV particle theory explains optical phenomena, yet it also explains other physical phenomena including some otherwise only accessible through quantum mechanics (such as the electron spin g-factor) and general relativity (including the Lorentz and relativistic Doppler). It also provides solutions for phenomena of unknown causation, such as asymmetrical baryogenesis, unification of the interactions, and reasons for nuclide stability/instability. Consequently, the implication is that NLHV theories have the potential to represent a deeper physics that may underpin and unify quantum mechanics, general relativity, and wave theory.

Monogenic features of urolithiasis: A comprehensive review

Objective: Urolithiasis formation has been attributed to environmental and dietary factors. However, evidence is accumulating that genetic background can contribute to urolithiasis formation. Advancements in the identification of monogenic causes using high-throughput sequencing technologies have shown that urolithiasis has a strong heritable ***: This review describes monogenic factors implicated in a genetic predisposition to urolithiasis. Peer-reviewed journals were evaluated by a PubMed search until July 2023 to summarize disorders associated with monogenic traits, and discuss clinical implications of identification of patients genetically susceptible to urolithiasis ***: Given that more than 80% of urolithiases cases are associated with calcium accumulation, studies have focused mainly on monogenetic contributors to hypercalciuric urolithiases, leading to the identification of receptors, channels, and transporters involved in the regulation of calcium renal tubular reabsorption. Nevertheless, available candidate genes and linkage methods have a low resolution for evaluation of the effects of genetic components versus those of environmental, dietary, and hormonal factors, and genotypes remain undetermined in the majority of urolithiasis ***: The pathophysiology underlying urolithiasis formation is complex and multifactorial, but evidence strongly suggests the existence of numerous monogenic causes of urolithiasis in humans.
