Self-rated Health in Youth with Different Screen Time in Their Adolescence: Tehran Lipid and Glucose Study.

Background: The long-term effects of childhood screen time on health-related quality of life (HRQoL) are still unclear. This study aimed to investigate the relationship between screen time during adolescence and sex-specific HRQoL in early youth.

Methods: We studied the data from 642 adolescents aged 13-19 years, who participated in the Tehran Lipid and Glucose Study from 2005 to 2011 (baseline) with complete data on HRQoL in their early adulthood (22-28 years at the last follow-up).

Plasmonic slanted slit gratings for efficient through-substrate light-plasmon coupling and sensing.

We present an experimental study of plasmonic slanted slit gratings (PSSGs) designed to achieve directional coupling between an incident light beam and surface plasmon polaritons (SPPs) propagating along the surface of the structure. We also investigate mirrored PSSG pairs interconnected by a plasmonic slab waveguide. The structures are fabricated using direct milling by a gallium focused ion beam (FIB).

A systematic review of the relationship between magnetic resonance imaging based resting-state and structural networks in the rodent brain.

Recent developments in rodent brain imaging have enabled translational characterization of functional and structural connectivity at the whole brain level . Nevertheless, fundamental questions about the link between structural and functional networks remain unsolved. In this review, we systematically searched for experimental studies in rodents investigating both structural and functional network measures, including studies correlating functional connectivity using resting-state functional MRI with diffusion tensor imaging or viral tracing data.

Plasmonic Biosensor on the End-Facet of a Dual-Core Single-Mode Optical Fiber.

Optical biosensors target widespread applications, such as drug discovery, medical diagnostics, food quality control, and environmental monitoring. Here, we propose a novel plasmonic biosensor on the end-facet of a dual-core single-mode optical fiber. The concept uses slanted metal gratings on each core, interconnected by a metal stripe biosensing waveguide to couple the cores via the propagation of surface plasmons along the end facet.

Health-Related Quality of Life in Those with Persistent or Transient Obesity Phenotypes during Two Decades: Tehran Lipid and Glucose Study.

Introduction: The current study aimed to investigate the association of three stable obesity phenotypes (persistent metabolically healthy normal weight [P MHNW], persistent metabolically healthy obese [P MHO], persistent metabolically unhealthy obese [P MUO]), and one transient (MHO to MUO) obesity phenotype throughout 18 years with health-related quality of life (HRQoL).

Methods: 1,932 participants (649 men and 1,283 women) who completed the HRQoL questionnaire during 2016-2019 were recruited in the current investigation. Based on the body mass index and metabolic status, participants were classified into four obesity phenotypes, including (1) P MHNW, (2) P MHO, (3) P MUO, and (4) transient from MHO to MUO.

Body mass index trajectories from childhood concerning emotional states in young adulthood: Tehran Lipid and Glucose Study.

This study aimed to identify body mass index (BMI) trajectories from childhood and their relationships with depression, anxiety, and stress symptoms in young adulthood. A total of 687 children aged 4-18 years were recruited from the Tehran Lipid and Glucose Study. Throughout 18 years of follow-up, BMI was measured every 3 years for a maximum of 6 data points.

Barriers Toward the National Program for Prevention and Control of Diabetes in Iran: A Qualitative Exploration.

Background: Despite the achievements of the national program for the prevention and control of diabetes (NPPCD) over the past two decades, the available evidence indicates a high prevalence of this disease in Iran. This qualitative study aims to investigate barriers to the NPPCD by pursuing the perspectives of relevant policy-makers, planners, and healthcare workers.

Methods: A grounded theory approach was used to analyze participants' perceptions and experiences.

Long-Term Parallel Changes of Physical Activity and Body Mass Index in Different Predisposing Risk Trajectories of Obesity.

Background: The long-term parallel changes of physical activity and body mass index (BMI) in the adult population are still unclear. The present study assessed the association between physical activity and BMI over time, considering obesity risk trajectory groups and sex strata.

Methods: Total sample of 6897 adults was followed for an average of 12 years.

Substitution of calorie restriction for protective effects of estrogen on cardiometabolic risk factors and oxidative stress in obese postmenopausal rat model.

Estrogen has an anti-obesity effect and plays an important role in improving cardiometabolic disorders. Weight loss and reduction in calorie intake impede the development of obesity-related cardiometabolic risk factors. Therefore, we investigated the substitution of calorie restriction for effects of estrogen on cardiometabolic risk factors and oxidative stress in obese postmenopausal rat model.

Dual mode operation, highly selective nanohole array-based plasmonic colour filters.

Taking advantage of nanostructured metal films as plasmonic colour filters (PCFs) has been evolved remarkably as an alternative to the conventional technologies of chemical colour filtering. However, most of the proposed PCFs depict a poor colour purity focusing on generating either the additive or subtractive colours. In this paper, we present dual mode operation PCFs employing an opaque aluminium film patterned with sub-wavelength holes.
