This study explores the use of plant extract to reduce corrosion on low-carbon steel reinforcement embedded in concrete. It is globally known that structures exposed to corrosive environments can collapse due to deterioration of the steel rods embedded in the concrete. The corrosion-inhibition potential of leaves, bark, and root extracts of Boswelia dalzelia (BD) on concrete reinforcement was investigated using a half-cell potentiometer and scanning electron microscopy (SEM) analysis. The half-cell potential readin [...]

Molecular dynamics is an essential tool for studying the formation of surface patterns in their early stages under low-energy bombardment. Recently, it has been shown that semiconductor surfaces such as Si can reorganize under ultra-low-energy conditions to form surface patterns. In this work, we investigate the formation of patterns on metal surfaces under these conditions. To accelerate the process, a longitudinal substrate model was employed, with clusters selected as projectiles. As is well known, pattern forma [...]

The glymphatic system is a glia-dependent network surrounding blood vessels that facilitates the exchange of cerebrospinal fluid (CSF) and interstitial fluid, playing a crucial role in clearing neuro-metabolites from the brain. This system’s efficiency in transporting waste significantly increases during non-rapid eye movement non-REM sleep. Recent findings suggests that malfunctioning of the glymphatic system might be linked to neurodevelopmental disorders such as attention-deficit/hyperactivity disorder (ADHD), a [...]

A new series of bis-quadridentate ligands (L1-L3) and their corresponding zinc(II) complexes (Complex 1-3) were rationally designed, synthesized, and characterized. The ligand framework features multiple donor sites that enable stable coordination to zinc(II), yielding well-defined metal complexes. The structures of the synthesized compounds were confirmed using a combination of analytical and spectroscopic techniques. Thermal gravimetric analysis revealed that all zinc complexes exhibit exceptional thermal stabili [...]

Stress is a multifaceted response involving physiological, psychological, and behavioural processes, with neurotransmitters such as serotonin, dopamine, and norepinephrine playing key modulatory roles. This study aimed to map global research trends on stress and neurotransmitters, identify thematic clusters, and highlight emerging frontiers relevant to health and disease. A bibliometric analysis was conducted on 4,132 publications indexed in Scopus between 2000 and 2023. Data were retrieved and processed using Exce [...]

Noonan syndrome (NS) is an autosomal dominant disorder with a wide spectrum of symptoms and clinical phenotypes, including short stature, congenital heart defects (CHD), and distinctive facial features. A pathogenic variant in the PTPN11 gene is the major cause of NS. This is a preliminary study in Indonesia involving 29 patients with clinical features of NS. Detailed clinical and echocardiography data were collected. Genomic DNA was extracted from a peripheral blood sample. Exome sequencing or PCR followed by Sang [...]

Perinatal mental health challenges are the number one complication of pregnancy and childbearing. Despite the growing need, substantial barriers to addressing perinatal mental health exist, including lack of infrastructure, policies, and workforce. Baby Talk, a free prenatal education program, sought to address this growing need through a brief intervention for those with a positive screening. Baby Talk partnered with a local suicide prevention program to develop a tool to enhance access to care and to support emot [...]
