Spectroscopic approach to optimize the biogenic silver nanoparticles for photocatalytic removal of ternary dye mixture and ecotoxicological impact of treated wastewater.

The fabricating of extremely effective, economical, ecologically safe, and reusable nanoparticle (NP) catalysts for the removal of water pollution is urgently needed. This study, spectroscopically optimizes the process parameters for the biogenic synthesis of AgNP catalysts using Cledrdendrum infortunatum leaf extract. The optimization of several synthesis parameters was systematically studied using UV-Vis spectroscopy to identify the ideal conditions for AgNPs formation.

GQD@NiFe-LDH Nanosheets for Photocatalytic Activity towards Textile Dye Degradation via Lattice Contraction.

The functionalized NiFe-LDH with photosensitized GQDs were synthesized through the hydrothermal route by differing the amount of GQDs solution and studied its efficacy towards the mineralization of textile dyes under visible light. The synthesized samples were characterized by XRD, FESEM, HRTEM, DRUV-Vis, RAMAN, XPS, and BET. The combined effect of the hexagonal carbon lattice in GQD and open layered porous structure of NiFe-LDH nanosheets results in the contraction of the lattice.

Birth Defects among Newborns in a Tertiary Care Centre: A Descriptive Cross-sectional Study.

Introduction: The incidence of birth defects is 2-3% in the general population but it is increasing. An estimated 303,000 newborns die within 4 weeks of birth every year, worldwide, due to congenital anomalies. The objective of this study was to find out the prevalence of birth defects among newborns in a tertiary care centre.

Prevalence and risk factors for maternal mortality at a tertiary care centre in Eastern Nepal- retrospective cross sectional study.

Background: The maternal mortality ratio is a significant public health indicator that reflects the quality of health care services. The prevalence is still high in developing countries than in the developed countries. This study aimed to determine the MMR and identify the various risk factors and causes of maternal mortality.

Amniotic fluid embolism: A rare cause of maternal collapse-A case report.

High index of suspicion of amniotic fluid embolism should be considered in any intrapartum or postpartum collapse where the obvious cause of collapse is not identified.

Overt Hyperthyroidism in Third Trimester of Pregnancy: A Case Report.

Hyperthyroidism is a state of excessive thyroid function. The most common cause of hyperthyroidism is Graves' disease. Overt hyperthyroidism if not treated can have serious outcome on the mother and the fetus.

Molecular interactions of MnO@RGO (manganese dioxide-reduced graphene oxide) nanocomposites with bovine serum albumin.

Graphene based materials have attracted global attention due to their excellent properties. GO-metal oxide nanocomposites have been conjugated with biomolecules for the development of novel materials and potentially used as biomarkers. Herein, a detailed study on the interaction of Bovine serum albumin (BSA) with MnO@RGO (manganese dioxide-reduced graphene oxide) nanocomposites (NC) has been carried out.

Two-dimensional fetal biometry versus three-dimensional fractional thigh volume for ultrasonographic prediction of birthweight.

Objective: To develop and validate birthweight prediction models using fetal fractional thigh volume (TVol) in an Indian population, comparing them with existing prediction models developed for other ethnicities.

Methods: A prospective observational study was conducted among 131 pregnant women (>36 weeks) attending a tertiary hospital in New Delhi, India, for prenatal care between December 1, 2014, and November 1, 2016. Participants were randomly divided into formulating (n=100) and validation (n=31) groups.

Repercussion of Solid state vs. Liquid state synthesized p-n heterojunction RGO-copper phosphate on proton reduction potential in water.

The same copper phosphate catalysts were synthesized by obtaining the methods involving solid state as well as liquid state reactions in this work. And then the optimised p-n hybrid junction photocatalysts have been synthesized following the same solid/liquid reaction pathways. The synthesized copper phosphate photocatalyst has unique rod, flower, caramel-treat-like morphology.

3 D Co (PO ) -Reduced Graphene Oxide Flowers for Photocatalytic Water Splitting: A Type II Staggered Heterojunction System.

The design, synthesis, and photoelectrochemical characterization of Co (PO ) , a hydrogen evolving catalyst modified with reduced graphene oxide (RGO), is reported. The 3 D flowerlike Co (PO ) heterojunction system, consisting of 3 D flowerlike Co (PO ) and RGO sheets, was synthesized by a one-pot in situ photoassisted method under visible-light irradiation, which was achieved without the addition of surfactant or a structure-directing reagent. For the first time, Co (PO ) is demonstrated to act as a hydrogen evolving catalyst rather than being used as an oxygen evolving photoanode.

Lupus erythematosus-lichen planus overlap syndrome in an HIV-infected individual.

Lupus erythematosus-lichen planus (LE-LP) overlap syndrome is an uncommon disorder with clinical, histological and/or immunopathological features of both diseases. We report a case of LE-LP overlap syndrome in a patient with HIV infection. To the best of our knowledge, LE-LP overlap syndrome with HIV infection has never been reported in literature.

Granular Cell Tumor: An Uncommon Benign Neoplasm.

Granular cell tumor is a distinctly rare neoplasm of neural sheath origin. It mainly presents as a solitary asymptomatic swelling in the oral cavity, skin, and rarely internal organs in the middle age. Histopathology is characteristic, showing polyhedral cells containing numerous fine eosinophilic granules with indistinct cell margins.

Huge Nevus Lipomatosus Cutaneous Superficialis on Back: An Unusual Presentation.

Nevus lipomatosus cutaneous superficialis (NLCS) is a benign dermatosis, histologically characterized by the presence of mature ectopic adipocytes in the dermis. We hereby report a case of a 10-year-old boy who presented with multiple huge swellings on the scapular regions and lower back. The lesions were surmounted by small papules, along with peau-d orange appearance at places.

Porokeratotic eccrine ostial and dermal duct nevus.

Porokeratotic eccrine ostial and dermal duct nevus (PEODDN) is a rare nevoid condition characterized by asymptomatic grouped keratotic papules and plaques with a linear pattern on the extremities, having distinct porokeratotic histopathological features. The lesions usually present at birth or in childhood. We present here a case of late-onset PEODDN in a 23-year-old man who had lesions on the palm, forearm, arm and the chest along the lines of Blaschko, strictly localized to the left side of the body.

Generalized benign acanthosis nigricans in an infant.

The generalized form of acanthosis nigricans, especially in infants, is extremely rare. Herein we report a 1-year-old female child who developed generalized acanthosis nigricans without any evidence of internal malignancy or endocrine disorder. This case is being reported for its rarity.

One pot synthesis of water-dispersible dehydroascorbic acid coated Fe3O4 nanoparticles under atmospheric air: blood cell compatibility and enhanced magnetic resonance imaging.

Water dispersible and biologically important molecule dehydroascorbic acid (DHA, capable to cross the blood brain barrier) coated Fe3O4 superparamagnetic nanoparticles having an average size of ∼6 nm were synthesized through one pot aqueous coprecipitation method under atmospheric air. An antioxidant ascorbic acid (AA) used in the synthesis oxidized itself to dehydroascorbic acid (DHA) to consume dissolved or available oxygen in reaction mixture which died away the oxidative impact of atmospheric air and formed DHA encapsulated the Fe3O4 nanoparticles which stabilized the Fe3O4 nanoparticles and significantly enhanced their colloidal solubility in water. Fe3O4 phase, superparamagnetic property, DHA coating and stable colloidal solubility in water were confirmed by means of XPS, VSM, IR and zeta potential analysis respectively.
