Deconvolution-based partial volume correction of PET images with parallel level set regularization.

Phys Med Biol 2021 Jun 22. Epub 2021 Jun 22.

Radiology and Physics, The University of British Columbia, Vancouver, British Columbia, V6T 1Z4, CANADA.

The partial volume effect (PVE), caused by the limited spatial resolution of positron emission tomography (PET), degrades images both qualitatively and quantitatively. Anatomical information provided by magnetic resonance (MR) images has the potential to play an important role in partial volume correction (PVC) methods. Post-reconstruction MR-guided PVC methods typically use segmented MR tissue maps, and further, assume that PET activity distribution is uniform in each region, imposing considerable constraints through anatomical guidance.

Early defects in mucopolysaccharidosis type IIIC disrupt excitatory synaptic transmission.

JCI Insight 2021 Jun 22. Epub 2021 Jun 22.

Medical Genetics, CHU Sainte-Justine, Montréal, Canada.

The majority of patients affected with lysosomal storage disorders (LSD) exhibit neurological symptoms. For mucopolysaccharidosis type IIIC (MPSIIIC), the major burdens are progressive and severe neuropsychiatric problems and dementia primarily thought to stem from neurodegeneration. Using the MPSIIIC mouse model we studied whether clinical manifestations preceding massive neurodegeneration arise from synaptic dysfunction. Read More

Acoustic Mist Ionization Mass Spectrometry for Ultrahigh-Throughput Metabolomics Screening.

Anal Chem 2021 Jun 22. Epub 2021 Jun 22.

School of Biosciences, University of Birmingham, Edgbaston, Birmingham B15 2TT, U.K.

Incorporating safety data early in the drug discovery pipeline is key to reducing costly lead candidate failures. For a single drug development project, we estimate that several thousand samples per day require screening (<10 s per acquisition). While chromatography-based metabolomics has proven value at predicting toxicity from metabolic biomarker profiles, it lacks sufficiently high sample throughput. Read More

[State of corneal nerve fibers after laser-assisted in situ keratomileusis].

Vestn Oftalmol 2021 ;137(3):39-48

Research Institute of Eye Disease, Moscow, Russia.

Purpose: To assess the state of corneal nerve fibers (CNF) based on quantitative parameters after laser correction of myopia using LASIK.

Material And Methods: The study examined 141 eyes - 80 eyes with myopia and 61 emmetropic eyes. In 47 cases a microkeratome was used to form a corneal flap, and in 33 cases a femtosecond laser was used (LASIK and FemtoLASIK, respectively). Read More

[Keratitis associated with contact lens correction in children and adolescents].

Vestn Oftalmol 2021 ;137(3):21-25

Children's Clinical Hospital of the Ministry of Health of the Republic of Tatarstan, Kazan, Russia.

Currently, the number of contact lens users in the world is approximately 10% of the total population of developed countries. Despite the undeniable advantages of contact lenses over eyeglasses, complications are an unpleasant aspect of their use. An analysis of the literature showed that purulent-inflammatory complications have not been fully described. Read More

[Results of a two-year clinical study of myopia control with bifocal defocus-inducing soft contact lenses].

Vestn Oftalmol 2021 ;137(3):5-12

National Myopia Institute, Moscow, Russia.

The development of methods for myopia control remains one of the most topical trends in modern ophthalmology. Optical approaches to myopia control employ the induction of peripheral myopic defocus, which can be done with the use of multifocal soft contact lenses (SCLs).

Purpose: To review the results of a two-year multicenter clinical study of myopia control with bifocal defocus-inducing SCLs. Read More

Microfluidic processing of stem cells for autologous cell replacement.

Stem Cells Transl Med 2021 Jun 22. Epub 2021 Jun 22.

Institute for Vision Research, Department of Ophthalmology and Visual Science, Carver College of Medicine, University of Iowa, Iowa City, Iowa, USA.

Autologous photoreceptor cell replacement is one of the most promising approaches currently under development for the treatment of inherited retinal degenerative blindness. Unlike endogenous stem cell populations, induced pluripotent stem cells (iPSCs) can be differentiated into both rod and cone photoreceptors in high numbers, making them ideal for this application. That said, in addition to photoreceptor cells, state of the art retinal differentiation protocols give rise to all of the different cell types of the normal retina, the majority of which are not required and may in fact hinder successful photoreceptor cell replacement.

[Prevalence and predictors of rebound deformity in the frontal plane : A literature review].

Orthopade 2021 Jun 22. Epub 2021 Jun 22.

Klinik für Orthopädie (Friedrichsheim), Universitätsklinikum Frankfurt, Marienburgstraße 2, 60528, Frankfurt am Main, Deutschland.

The present literature review presents the current state of the art on the prevalence and causes of the rebound phenomenon after successful correction of leg axis deformity using temporary epiphysiodesis in children and adolescents. A total of 20 studies was included by three independent reviewers. The validity of most studies regarding the rebound incidence is limited by a non-standardized follow-up after plate removal, heterogeneous patient groups with a small number of cases, and missing information on the definition of rebound.
