Bioinorganic chemical composition of the lens of human and experimental animals (cows, dogs, rats, rabbits) have been analyzed in various studies. In most cases, the studies employed different methods to determine the gross (total) composition of chemical elements and their concentrations in the examined samples. Less frequently, they included an assessment of the distribution of chemical elements in the lens and correlation of their concentration with its morphological changes. Chemical elements from all groups (series) of the periodic classification system were discovered in the lens substance...

Graded refractive index lenses are inherent to advanced visual systems in animals. By understanding their formation and local optical properties, significant potential for improved ocular healthcare may be realized. We report a novel technique measuring the developing optical power of the eye lens, in a living animal, by exploiting the orthogonal imaging modality of a selective plane illumination microscope (SPIM). We have quantified the maturation of the lenticular refractive index at three different visible wavelengths using a combined imaging and ray tracing approach...

This research aimed to reveal the general morphology and topographic distribution of lingual papillae, epithelial characteristics, mucosal structure, and glands with their mucin content in the sheep tongue, with consideration of species-specific characteristics. The tongues of ten sheep were analyzed for this purpose. Filiform and fungiform papillae existed within the borders of the ventral surface of the lingual apex. The majority of the filiform papillae had multiple secondary projections. Fungiform papillae were also seen on the lingual torus among lenticular papillae, as well as 6 to 10 circumvallate papillae arranged on its caudal border...

We describe a surgical technique for the correction of isolated congenital lenticular coloboma associated with high corneal astigmatism. Transscleral fixation of the capsular bag with a single eyelet Cionni capsular tension ring was followed by in-the-bag implantation of a toric intraocular lens (IOL). This lead to complete correction of the lenticular defect and perfect alignment of the toric lens. In this case, the child attained an unaided distance visual acuity of 20/30 following amblyopia therapy and a well-aligned toric IOL at 12 months of follow-up...

From December 2016 to May 2017, 22 phytoplankton surface samples were collected with a 20-μm mesh net at three islands of the Archipiélago de Revillagigedo (Partida, Socorro and San Benedicto), Mexican Pacific. The sites depth was approximately 20-80 m; the surface water temperature was 21-27 °C. The potentially toxic benthic dinoflagellate Ostreopsis lenticularis was present in all the samples. Cells had a lenticular to broadly oval shape, 65-100 μm long and 50-80 μm wide. The taxonomy of the genus Ostreopsis has been unclear due to equivocal ascribing some taxonomic features among species...

PURPOSE: The exact etiopathogenesis of steroid-induced cataracts (SIC) is not known. Although oxidative stress is one of the most acceptable hypotheses, the exact molecular events in steroid-induced oxidative events in the lens need to be clarified. In addition, to the best of our knowledge, the innate immune system components in SIC formation have not been studied previously. The aim of the present study was to study the oxidative system and the innate immune system components in the cataractous lenses of a developing chick embryo SIC model...

We report a case of anterior megalophthalmos and complicated cataract, with apparently smaller lens in both eyes. The right eye had spontaneous retinal detachment. The child underwent cataract surgery in both the eyes with retinal detachment surgery in the right eye. Due to small size of the lenticular bag, a downsized customized intraocular lens (IOL) was implanted. Postoperatively, the IOL was well centered with ambulatory vision till 3 years of follow-up. This case describes this rare disorder and its association with apparently small-sized lens and discusses the course of its management, highlighting the visual rehabilitation with customization of IOLs...

The ∼3.48 billion-year-old Dresser Formation, Pilbara Craton, Western Australia, is a key geological unit for the study of Earth's earliest life and the habitats it occupied. Here, we describe a new suite of spheroidal to lenticular microstructures that morphologically resemble some previously reported Archean microfossils. Correlative microscopy shows that these objects have a size distribution, wall ultrastructure, and chemistry that are incompatible with a microfossil origin and instead are interpreted as pyritized and silicified fragments of vesicular volcanic glass...

Laugier-Hunziker syndrome (LHS, also termed idiopathic lenticular mucocutaneous hyperpigmentation) is an unusual condition characterized by progressive pigmentation of the mucous membranes. LHS displays a benign course and is not associated with malignancy. Here we present a case of LHS with a 7-year follow-up. We document metachronous oral melanoacanthomas in this individual. In addition, we found that the oral melanotic macules in this patient waxed and waned in a cyclical manner. To our knowledge, this is the first report of these findings in the context of LHS...

A 58-year-old man consulted our hospital due to a 2-year history of dysarthria and a 1-month history of blepharospasm. In addition to the ataxic dysarthria and blepharospasm, a neurological examination demonstrated slight ataxia of the trunk and lower limbs. Brain MRI demonstrated atrophy of the upper portion of the cerebellar vermis. Gene analysis established a diagnosis of spinocerebellar ataxia type 31 (SCA31). SPECT with the three-dimensional stereotaxic ROI template (3DSRT) software program demonstrated hyperperfusion in the lenticular nucleus and thalamus...

The diversity of Aspergillus species in clinical samples is continuously increasing. Species under the former name Eurotium, currently accommodated in section Aspergillus of the genus Aspergillus, are xerophilic fungi widely found in the human environment and able to grow on substrates with low water activity. However, their prevalence in the clinical setting is poorly known. We have studied the presence of these species in a set of clinical samples from the United States using a multilocus sequence analysis based on the internal transcribed spacer (ITS) region of the rRNA, and fragments of the genes β-tubulin (BenA), calmodulin (CaM), and polymerase II second largest subunit (RPB2)...
