Do Patients With Functional Hallux Limitus Have a Low-Lying or Bulky FHL Muscle Belly?

Background: Functional hallux limitus (FHLim) refers to a limitation of hallux dorsiflexion when the first metatarsal head is under load, whereas physiologic dorsiflexion is measured in the unloaded condition. Limited excursion of the flexor hallucis longus (FHL) in the retrotalar pulley has been identified as a possible cause of FHLim. A low-lying or bulky FHL muscle belly could be the cause of this limitation.

Scintillation light detection in the 6-m drift-length ProtoDUNE Dual Phase liquid argon TPC.

DUNE is a dual-site experiment for long-baseline neutrino oscillation studies, neutrino astrophysics and nucleon decay searches. ProtoDUNE Dual Phase (DP) is a 6   6   6 m liquid argon time-projection-chamber (LArTPC) that recorded cosmic-muon data at the CERN Neutrino Platform in 2019-2020 as a prototype of the DUNE Far Detector. Charged particles propagating through the LArTPC produce ionization and scintillation light.

Triangle Singularity as the Origin of the a_{1}(1420).

The COMPASS Collaboration experiment recently discovered a new isovector resonancelike signal with axial-vector quantum numbers, the a_{1}(1420), decaying to f_{0}(980)π. With a mass too close to and a width smaller than the axial-vector ground state a_{1}(1260), it was immediately interpreted as a new light exotic meson, similar to the X, Y, Z states in the hidden-charm sector. We show that a resonancelike signal fully matching the experimental data is produced by the decay of the a_{1}(1260) resonance into K^{*}(→Kπ)K[over ¯] and subsequent rescattering through a triangle singularity into the coupled f_{0}(980)π channel.

First Measurement of Transverse-Spin-Dependent Azimuthal Asymmetries in the Drell-Yan Process.

The first measurement of transverse-spin-dependent azimuthal asymmetries in the pion-induced Drell-Yan (DY) process is reported. We use the CERN SPS 190  GeV/c π^{-} beam and a transversely polarized ammonia target. Three azimuthal asymmetries giving access to different transverse-momentum-dependent (TMD) parton distribution functions (PDFs) are extracted using dimuon events with invariant mass between 4.

[Comprehensive study of the iris in transformed light in simple glaucoma].

Complex examination of the iris under light transformed by various methods - iridochromoscopy with iridochromophotography, transillumination in red light, and fluorescein angiography - was performed on 26 eyes of patients with simple glaucoma and 24 normal eyes of subjects aged between 42 and 76 years. All the methods employed revealed iris changes in 100% of the simple glaucoma cases. The differences found between the study group and the controls were significant (P = 0.

[Iris examination in transformed light in primary open-angle glaucoma].

The iris was examined in transformed light by iridochromoscopy, iridochromophotography, biomicroscopy in polarized light, transillumination in red light, and fluorescent iridoangiography in 83 eyes of patients with primary open-angle glaucoma and 117 eyes of normal reference subjects. The examinations have shown the prevalence of trophic and vascular shifts in the iris of all glaucoma patients as against the reference patients (R 0.05).

[The complex study of the iris in transformed light].

Complex investigations of the iris in a transformed light by methods of iridochromoscopy, iridochromophotography, examination in a polarized light, transillumination in red light and fluorescence angiography was conducted in 25 eyes of patients with open-angle glaucoma, 10 eyes of patients with anterior flaccid uveitis and in 23 healthy eyes (a control group). It was found that in patients with open-angle glaucoma and anterior flaccid uveitis trophic and vascular changes in the iris predominated, as compared with control. The most typical for open-angle glaucoma changes in the iris were atrophy of the stroma with predominant involvement of the pupillary zone, exogenic pigmentation of the pupillary and ciliary zones, destruction of the pigment margin of the pupil, thickening of the anterior border layer, pseudoexfoliation of the pupillary margin, defects in the posterior pigment layer, being more extensive in the pupillary zone, as well as disturbances in permeability of the iris in a combination with hypoperfusion and rare bundles of microneovascularization in the area of a lesser arterial circle and the ciliary zone.

[A simple method for automonitoring of the visual fields to be used in screening for glaucoma].

A simple method for automonitoring the visual field nasal border is suggested, fit for screening examinations as well. It consists in successive putting of one, two, or four fingers to the bridge of the nose. In a reference group of normal subjects putting one finger to the bridge of the nose induced narrowing of the nasal border of the visual field by 17 degrees on an average, by 26 degrees with two fingers, and by 34 degrees with four fingers.

[EEG analysis in patients in the acute stage of cerebral infarction by the methods of image recognition].

The brain bioelectric activity was studied in 280 acute stroke patients. Factor and cluster analyses were applied to 4 EEG groups: recordings of left and right hemispheres with and without a damaged foci. The hemispheral lesion contralateral to the damaged focus was shown to differ in reactive EEG shifts what the hemisphere is, namely left or right.

[Analysis of autonomic disorders of cerebral origin].

Clinico-encephalographic examinations of patients suffering from neuroses and neurosis-like states with marked vegetative disturbances were carried out. Regular connections between the integral electrographic phenomena and individual features of the EEG on the one hand, and the character and the depth of the vegetovascular, metabolic, endocrinal, emotional and neurotic disturbances on the other were revealed. The averaged models of EEGs constructed with the aid of an electronic computer can be used for ordinary practical evaluation of EEGs with the purpose of specifying the localization of the affection in individual links of the limboreticular system.
