Zero-dose children pose a key challenge in immunization programs due to their association with access to the health system and primary healthcare services. Examining zero-dose aids an in-depth understanding of healthcare disparities among children and caregivers. The disparity in utilization of maternal and child health services raises concerns about the potential consequences of unintended pregnancies on vaccine uptake.

Toward Rational Design of Mononuclear Nickel Complexes as Water Oxidation Catalysts Exploring the Ligand Effects on the Rate-Determining Step.

The major impediment in realizing a carbon-neutral hydrogen fuel economy is the cost and inadequacy of contemporary electrochemical water splitting approaches towards the energy intensive oxygen evolution reaction (OER). The O-O bond formation in the water oxidation half-cell reaction is both kinetically and thermodynamically challenging and amplifies the overpotential requirement in most of the active water oxidation catalysts. Herein, density functional theory is employed to interrogate 20 Ni(II) complexes, out of which 17 are in silico designed molecular water oxidation catalysts, coordinated to electron-rich tetra-anionic redox non-innocent phenylenebis(oxamidate) and dibenzo-1,4,7,10-tetraazacyclododecane-2,3,8,9-tetraone parent ligands and their structural analogues, and identify the role of substituent changes or ligand effects in the order of their reactivity.

Evolution in the Design of Water Oxidation Catalysts with Transition-Metals: A Perspective on Biological, Molecular, Supramolecular, and Hybrid Approaches.

Increased demand for a carbon-neutral sustainable energy scheme augmented by climatic threats motivates the design and exploration of novel approaches that reserve intermittent solar energy in the form of chemical bonds in molecules and materials. In this context, inspired by biological processes, artificial photosynthesis has garnered significant attention as a promising solution to convert solar power into chemical fuels from abundantly found HO. Among the two redox half-reactions in artificial photosynthesis, the four-electron oxidation of water according to 2HO → O + 4H + 4e comprises the major bottleneck and is a severe impediment toward sustainable energy production.

Mission Indradhanush and Intensified Mission Indradhanush-Success Story of India's Universal Immunization Program and the Role of Mann Ki Baat in Bridging the Immunization Gap.

Child immunization is crucial for reducing the morbidity and mortality associated with vaccine-preventable diseases (VPDs). The program grew over the years, however, progress towards full immunization coverage (FIC) remained slow, with only 44% of children fully immunized in 1992-1993, and 62% in 2015-2016, as reported in the National Family Health Survey. To address this challenge, Government of India launched Routine Immunization intensification drive- Mission Indradhanush (MI) in 2014, with the aim of achieving 90% FIC.

Exploring the Pattern of Immunization Dropout among Children in India: A District-Level Comparative Analysis.

The dropout rate is one of the determinants of immunization coverage and program performance, program continuity, and follow-up. The dropout rate refers to the proportion of vaccine recipients who did not finish their vaccination schedules, and it is determined by comparing the number of infants who started the schedule to the number who completed it. It is the rate difference between the first and final dosage or the rate difference between the first vaccination and the last vaccine dropout; thus, it denotes that the first recommended dose of vaccine was received, but that the subsequently recommended dose was missed.

Recent development in antihyperalgesic effect of phytochemicals: anti-inflammatory and neuro-modulatory actions.

Introduction: Pain is an unpleasant sensation triggered by noxious stimulation. It is one of the most prevalent conditions, limiting productivity and diminishing quality of life. Non steroidal anti inflammatory drugs (NSAIDs) are widely used as pain relievers in present day practice as pain is mostly initiated due to inflammation.

Activation of ERK signalling by Src family kinases (SFKs) in DRG neurons contributes to hydrogen peroxide (HO)-induced thermal hyperalgesia.

Concomitant generation of reactive oxygen species during tissue inflammation has been recognised as a major factor for the development and the maintenance of hyperalgesia, out of which HO is the major player. However, molecular mechanism of HO induced hyperalgesia is still obscure. The aim of present study is to analyse the mechanism of HO-induced hyperalgesia in rats.

Resveratrol alleviates inflammatory hyperalgesia by modulation of reactive oxygen species (ROS), antioxidant enzymes and ERK activation.

Objectives: Impact of ROS in development of hyperalgesia has recently motivated scientists to focus on ROS as novel target of anti-hyperalgesic interventions. However, role of ROS in molecular signaling of hyperalgesia is still poorly understood. The present study is aimed to analyze the effect of dietary antioxidant resveratrol on antioxidant defense system, ROS level and TNFR1-ERK signaling pathway during early and late phase of inflammatory hyperalgesia.

Anti-Nociceptive Effect of Resveratrol During Inflammatory Hyperalgesia via Differential Regulation of pro-Inflammatory Mediators.

Sensitization of nociceptive neurons by inflammatory mediators leads to hypersensitivity for normal painful stimuli which is termed hyperalgesia. Oxidative stress is an essential factor in pathological pain; therefore, antioxidants qualify as potential anti-hyperalgesic agents. The present study examines the efficacy of the natural antioxidant resveratrol in complete Freund's adjuvant (CFA) induced hyperalgesic rats.

Curcumin attenuates CFA induced thermal hyperalgesia by modulation of antioxidant enzymes and down regulation of TNF-α, IL-1β and IL-6.
