Photocrosslinkable starch cinnamyl ethers as bioinspired bio-based polymers.

A novel starch-based ether bearing cinnamyl functionalities, conferring photo-crosslinking properties, is synthesised by reaction with cinnamyl chloride in the presence of sodium hydroxide. Natural yuca was selected as a sustainable source of starch. Three different molar equivalents of reagents are used, affording starch-cinnamyl ethers with different degrees of substitution, ranging from 0.

Effectiveness of Defocus Incorporated Multiple Segments in Slowing Myopia Progression in Pediatric Patients as a Function of Age: Three-Year Follow-Up.

: The purpose of this study is to evaluate the effectiveness of Defocus Incorporated Multiple Segments (DIMSs) in slowing myopia progression in pediatric patients as a function of age. : This was a non-randomized experimenter-masked retrospective controlled observational study of European individuals aged 6-16 years with progressive myopia but no ocular pathology. We retrospectively reviewed the charts of the participants allocated to receive DIMS spectacles (Hoya MiyoSmart) or single-vision spectacle lenses (control group).

Rhodococcus erythropolis ATCC 4277 behavior against different metals and its potential use in waste biomining.

Rhodococcus erythropolis bacterium is known for its remarkable resistance characteristics that can be useful in several biotechnological processes, such as bioremediation. However, there is scarce knowledge concerning the behavior of this strain against different metals. This study sought to investigate the behavior of R.

Synthesis and Characterization of Alkoxysilane-Bearing Photoreversible Cinnamic Side Groups: A Promising Building-Block for the Design of Multifunctional Silica Nanoparticles.

The present study reports on the synthesis of a new alkoxysilane-bearing light-responsive cinnamyl group and its application as a surface functionalization agent for the development of SiO nanoparticles (NPs) with photoreversible tails. In detail, cinnamic acid (CINN) was activated with -hydroxysuccinimide (NHS) to obtain the corresponding NHS-ester (CINN-NHS). Subsequently, the amine group of 3-aminopropyltriethoxysilane (APTES) was acylated with CINN-NHS leading to the generation of a novel organosilane, CINN-APTES, which was then exploited for decorating SiO NPs.

Effectiveness of hyaluronic acid and arnica extract ophthalmic solution in reducing dry eye symptoms in pediatric population.

Aim: to assess the effectiveness of a new combination of topical solution with Hyaluronic Acid 0.2% and arnica extract 0.1% in reducing dry eye symptoms in a population of pediatric patients.

Treatment of Advanced Coats' Disease With Combination Therapy of Laser Photocoagulation, Intravitreal Ranibizumab, and Sub-Tenon Methylprednisolone Acetate.

Purpose: To investigate the efficacy of combination therapy with laser photocoagulation, intravitreal ranibizumab, and sub-Tenon methylprednisolone acetate in patients presenting with advanced Coats' disease.

Methods: This was a retrospective analysis of 16 patients who underwent laser photocoagulation combined with intravitreal ranibizumab and sub-Tenon methylprednisolone acetate between 2008 and 2017. The primary outcome was anatomic success and the secondary outcomes were globe preservation and final visual acuity.

OPHTHALMIA NEONATORUM in Italy: it is time for change.

Ophthalmia neonatorum (ON) refers to any conjunctivitis occurring in the first 28 days of life. In the past Neisseria gonorrhoeae was the most common cause of ON. It decreased with the introduction of prophylaxis at birth with the instillation of silver nitrate 2% (the Credè's method of prophylaxis).

Simultaneous transepithelial topographic-guided laser and cross-linking to correct irregular astigmatism in a pediatric patient.

Purpose: To evaluate an original approach for treating corneal ectasia and irregular astigmatism secondary to penetrating trauma in a pediatric patient.

Case Report: An 11 year old patient had a penetrating trauma in right eye when he was two and the refractive error was +1.50 diopters sphere -6.

Comparative analysis of visual outcomes of multifocal and monofocal intraocular lenses in congenital cataract surgery.

Purpose: To assess the impact on visual development of multifocal vs monofocal intraocular lenses (IOLs) implantation in children after congenital cataract surgery.

Setting: Ophthalmology Department, Bambino Gesù Children's Hospital, Rome, Italy.

Design: Retrospective interventional consecutive case series.

Dexamethasone Intravitreal Implant (Ozurdex) in Paediatric Patients with Non-infectious Intermediate Uveitis and Related Cystoid Macular Oedema: Evaluation of Macular Morphology and Function with Six-month Follow-up; a Deeper Role of MfERG?

Purpose: To evaluate the efficacy of Ozurdex implant by analyzing macular morphology and function in pediatric uveitis and related cystoid macular edema (CMO).

Methods: Main outcomes were visual acuity, mfERG and photopic ERG response, and central macular thickness. Mean values recorded at each time-point were compared to baseline and correlations between functional and anatomical parameters were evaluated.

Ocular manifestations and viral shedding in tears of pediatric patients with coronavirus disease 2019: a preliminary report.

Purpose: To evaluate ocular manifestations and severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) prevalence in the tears of children with coronavirus disease 2019 (COVID-19).

Methods: A total of 27 pediatric patients with confirmed COVID-19 infection hospitalized from March 16 to April 15, 2020, at the Bambino Gesù Children's Hospital were enrolled in the study. At admission, all patients showed ocular manifestations.

Iontophoretic Transepithelial Collagen Cross-Linking Versus Epithelium-Off Collagen Cross-Linking in Pediatric Patients: 3-Year Follow-Up.

Positive Youth Development Programs in Low- and Middle-Income Countries: A Conceptual Framework and Systematic Review of Efficacy.

Purpose: Positive youth development (PYD) has served as a framework for youth programs in high-income countries since the 1990s and has demonstrated broad behavioral health and developmental benefits. PYD programs build skills, assets, and competencies; foster youth agency; build healthy relationships; strengthen the environment; and transform systems to prepare youth for successful adulthood. The goal of this article was to systematically review the impact of PYD programs in low- and middle-income countries (LMICs).
