Oxygen-Passivated Sulfur Vacancies in Monolayer MoS for Enhanced Piezoelectricity.

Modern-day applications demand onboard electricity generation that can be achieved using piezoelectric phenomena. Reducing the dimensionality of materials is a pathway to enhancing the piezoelectric properties. Transition-metal dichalcogenides have been shown to exhibit high piezoelectricity.

Oxidation-induced modulation of photoresponsivity in monolayer MoS with sulfur vacancies.

Two-dimensional transition metal dichalcogenides (TMDs), such as MoS, hold great promise for next-generation electronics and optoelectronics due to their unique properties. However, the ultrathin nature of these materials renders them vulnerable to structural defects and environmental factors, which significantly impact their performance. Sulfur vacancies (V) are the most common intrinsic defects in MoS, and their impact on device performance in oxidising environments remains understudied.

CVD-Grown Monolayer MoS and GaN Thin Film Heterostructure for a Self-Powered and Bidirectional Photodetector with an Extended Active Spectrum.

Photodetector technology has evolved significantly over the years with the emergence of new active materials. However, there remain trade-offs between spectral sensitivity, operating energy, and, more recently, an ability to harbor additional features such as persistent photoconductivity and bidirectional photocurrents for new emerging application areas such as switchable light imaging and filter-less color discrimination. Here, we demonstrate a self-powered bidirectional photodetector based on molybdenum disulfide/gallium nitride (MoS/GaN) epitaxial heterostructure.

Structural and functional phenotypic features and molecular analysis of Indian patients with Bietti crystalline dystrophy.

Purpose: Bietti crystalline dystrophy (BCD) is a rare retinal dystrophy, uncommon in Indians. This study describes the various phenotypic features seen in the Indian population.

Methods: In this retrospective, descriptive case series, records of patients with either clinical or molecular diagnosis of BCD from 2009 to 2020 were perused.

Predicting Significant Hyperbilirubinemia in ABO Incompatibility: Is Cord Direct Antiglobulin Test Useful?

To study the prevalence of direct antiglobulin test (DAT) positivity and outcomes in babies with ABO incompatibility and the role of DAT in predicting need for phototherapy. This was an analytical retrospective cohort study conducted in a tertiary care hospital in South India. DAT was performed routinely in cord blood of all neonates born to O positive mothers.

Comparison Between Ranibizumab Biosimilar, Innovator Ranibizumab and Bevacizumab in a Real-World Situation.

Introduction: To analyze the efficacy of biosimilar ranibizumab compared to innovator ranibizumab and bevacizumab.

Methods: We retrospectively analyzed consecutive patients treated with biosimilar ranibizumab for wet age-related macular degeneration (AMD) and macular edema (ME) (due to diabetes and vein occlusion) and compared them with ranibizumab- and bevacizumab-treated patients.

Results: Of 202 patients, 67 (33.

Diabetic macular edema treatment guidelines in India: All India Ophthalmological Society Diabetic Retinopathy Task Force and Vitreoretinal Society of India consensus statement.

Diabetic macular edema (DME) is a common cause of moderate visual impairment among people with diabetes. Due to the rising number of people with diabetes in India, the absolute numbers of people with DME are significant. There are several treatment options for DME, and the choice of treatment is based on the availability of retinal specialists and infrastructure for the delivery of treatment.

Validation of a Hearing-Related Quality-of-Life Questionnaire for Parents and Deaf or Hard-of-Hearing Infants and Toddlers.

Objective: To design and validate a hearing-related quality-of-life questionnaire targeted toward parents and deaf or hard-of-hearing infants and toddlers: the Hearing-Related Infant/Toddler and Parent Quality of Life (HIP-QL) questionnaire.

Study Design: Cross-sectional questionnaire and prospective instrument validation.

Setting: Academic pediatric otolaryngology clinic.

Intramuscular Followed by Oral Vitamin A Supplementation in Neonates with Birth Weight from 750 to 1250 g: A Randomized Controlled Trial.

Multiple intramuscular (IM) injections of vitamin A have been shown to decrease bronchopulmonary dysplasia in very low birth weight (VLBW) neonates. However, this regime is neither practical nor popular. Oral vitamin A has failed to achieve adequate plasma levels.

Seeking equilibrium: The experiences of parents of infants and toddlers who are deaf/hard-of-hearing.

Purpose: To identify key determinants of the quality of life of caregivers of infants and toddlers (< 3 years) who are deaf/hard-of-hearing (DHH).

Methods: We conducted focus groups with providers for children who are DHH as well as interviews with hearing parents of infants and toddlers who are DHH. A multi-step qualitative analysis on interview data using grounded theory was performed, and an iterative analysis to investigate codes to characterize specific topics in caring for deaf infants and toddlers was conducted.

Heat stress decreases metabolic flexibility in skeletal muscle of growing pigs.

Heat-stressed pigs experience metabolic alterations, including altered insulin profiles, reduced lipid mobilization, and compromised intestinal integrity. This is bioenergetically distinct from thermal neutral pigs on a similar nutritional plane. To delineate differences in substrate preferences between direct and indirect (via reduced feed intake) heat stress effects, skeletal muscle fuel metabolism was assessed.

Mechanisms and benefits of granule cell latency coding in the mouse olfactory bulb.

Inhibitory circuits are critical for shaping odor representations in the olfactory bulb. There, individual granule cells can respond to brief stimulation with extremely long (up to 1000 ms), input-specific latencies that are highly reliable. However, the mechanism and function of this long timescale activity remain unknown.

Timescale-dependent shaping of correlation by olfactory bulb lateral inhibition.

Neurons respond to sensory stimuli by altering the rate and temporal pattern of action potentials. These spike trains both encode and propagate information that guides behavior. Local inhibitory networks can affect the information encoded and propagated by neurons by altering correlations between different spike trains.

Twins with senior-Loken syndrome.

Senior-Loken syndrome is a rare entity that combines familial juvenile nephronophthisis with retinal dystrophy. The eye disease may be congenital amaurosis of Leber type or pigmentary retinal degeneration and electroretinogram (ERG) helps in the diagnosis of these varieties. The disease progresses inexorably to chronic renal failure.

Pediatric interstitial lung disease.

This study was done to ascertain the symptomatology, clinical features and investigations pertaining to interstitial lung diseases (ILD) in children. The medical records of 16 children admitted over a 4-year period from June 2000 to May 2004 with progressive cough, dyspnea, and chest X-ray/High Resolution Computerized Tomography (HRCT) abnormalities suggesting ILD were retrospectively evaluated. Clinical findings, investigations, chest skiagrams, HRCT, bronchoalveolar lavage (BAL) and lung biopsy reports were analyzed.

Postoperative cardiac intensive care outcome for Down syndrome children.

Objective: The purpose of this study is to review the postoperative intensive care unit (ICU) course, complications and outcome of Down's syndrome children undergoing surgical repair of congenital heart diseases (CHD).

Methods: A retrospective chart review analysis of intensive care course and outcome of Down syndrome children undergoing surgical repair of congenital heart diseases (CHD) from May 2000 to May 2004. The study was conducted in the Pediatric Cardiac ICU, King Abdul-Aziz Cardiac Center of National Guard Hospital, Riyadh, Kingdom of Saudi Arabia.
