Meera Nair, Sardul Singh Sandhu, Anil Kumar Sharma
BACKGROUND: Induced Pluripotent Stem Cell (IPSC) Technology is the most advanced research as it offers an attractive alternative for establishing patient-specific IPSCs to recapitulate phenotypes of not only monogenic diseases (viz. Thalassaemia, Sickle cell anemia, Haemophilia, Tay-Sachs disease), but also late-onset polygenic diseases (viz. Parkinson's disease, Alzheimer's disease, schizophrenia). Over the hindsight, numerous studies of the past and current scientists have led to the production, maturation and understanding of induced pluripotent stem cell technology and its use in basic and clinical research...

This article is concerned with the physicality of envy primarily in early -modern, but also in eighteenth-century health contexts. The discussion brings together descriptions of the effects of envy on the body of the envier, mainly from works of physiology and health preservation, but also from literary and spiritual writings. These depictions of envy are studied beyond their symbolism and with a view to establish whether they are meaningful according to the medical theories of the time in which they occur...

RATIONALE: Genetic elucidation of cone-dominated retinal dystrophies in Indian subcontinent is much needed to identify and catalog underlying genetic defects. In this context, the present study recruited a consanguineous Indian family affected with autosomal recessive cone dystrophy (CD). Considering the huge genetic heterogeneity and recessive inheritance of the disease, we chose to dissect out causal variant in this family by whole exome sequencing (WES). PATIENT CONCERNS: In the recruited family, three of the six siblings had complaints of poor visual acuity, photophobia, and disturbed colour vision since early childhood...

Quantum characteristics of a driven series RLC nanoelectronic circuit whose capacitance varies with time are studied using an invariant operator method together with a unitary transformation approach. In particular, squeezing effects and nonclassical properties of a superposition state composed of two displaced squeezed number states of equal amplitude, but 180° out of phase, are investigated in detail. We applied our developments to a solvable specific case obtained from a suitable choice of time-dependent parameters...

BACKGROUND: It remains challenging to distinguish malaria from other fever causing infections, as a positive rapid diagnostic test does not always signify a true active malaria infection. This study was designed to determine the influence of other causes of fever, prior anti-malarial treatment, and a possible seasonality of the performance of a PfHRP2 RDT for the diagnosis of malaria in children under-5 years of age living in a malaria endemic area. METHODS: A prospective etiology study was conducted in 2015 among febrile children under 5 years of age in Burkina Faso...

The paper is an inquiry into the poetics of mourning and faith-based intervention in maladaptive grieving processes in Ethiopia. The paper discusses the ways loss is signified and analyses the meanings of ethno-cultural and psychospiritual practices employed to deal with maladaptive grief processes and their psychological and emotional after-effects. Hermeneutics provided the methodological framework and informed the analysis. The thesis of the paper is that the poetics of mourning and faith-based social interventions are interactionally based meaning making processes...

The Langmuir model has been extensively introduced into the field of environmental adsorption, while some studies showed that it was difficult for the model to describe the adsorption of sediments. The purpose of this paper is to recognize the applicability of the Langmuir model used in the adsorption of contaminants onto sediments quantitatively through the relationship between the error of Langmuir (δ) and site energy heterogeneity (σ). The formula for calculating δ in sediments was developed based on the heterogeneity parameters (m, n)...

The self-assembly of amyloidogenic peptides into β-sheet-rich aggregates is a general feature of many neurodegenerative diseases, including Alzheimer's disease, which signifies the need for the effective attenuation of amyloid aggregation toward alleviating amyloid-associated neurotoxicity. This study reports that photoluminescent carbon nanodots (CDs) can effectively suppress Alzheimer's β-amyloid (Aβ) self-assembly and function as a β-sheet breaker disintegrating preformed Aβ aggregates. This study synthesizes CDs using ammonium citrate through one-pot hydrothermal treatment and passivates their surface with branched polyethylenimine (bPEI)...

Little is known about endogenous descending control of itch. In chronic pain, descending pain inhibition is reduced as signified by lowered conditioned pain modulation (CPM). There are indications that patients with chronic itch may also exhibit reduced endogenous descending inhibition of itch and pain. This study aimed to investigate whether and the extent to which itch can be modulated by conditioning itch and pain stimuli. Twenty-six healthy volunteers participated. The study consisted of 5 conditions designed to systematically assess endogenous modulation of itch or pain: 1) itch-induced modulation of contralateral itch, 2) pain-induced modulation of contralateral itch, 3) pain-induced modulation of ipsilateral itch, 4) pain-induced modulation of contralateral pain, and 5) itch-induced modulation of contralateral pain...

Fibrodysplasia Ossificans Progressiva (FOP) is a progressive disease characterized by periods of heterotopic ossification of soft connective tissues, including ligaments. Though progress has been made in recent years in unraveling the underlying mechanism, patient-derived cell models are necessary to test potential treatment options. Periodontal ligament fibroblasts (PLF) from extracted teeth can be used to study deviant bone modeling processes in vitro since these cells are derived from genuine ligaments. They further provide a tool to study the hitherto unknown role of the bone morphogenesis protein receptor type 1 (BMPR-1) Activin A type 1 receptor ACVR1-R206H mutation in osteoclastogenesis...

BACKGROUND: The increasing significance of food products containing substances with antioxidative activi- ties is currently being observed. This is mainly due to the fact that pathogenic changes underlying some diseases are related to the carcinogenic effects of free radicals. Antioxidative compounds play an important role in supporting and enhancing the body’s defense mechanisms, which is useful in preventing some civili- zation diseases. Unfortunately, it has been already proved that some synthetic antioxidants pose a potential risk in vivo...

ChPur-α, a purine-rich element-binding protein, was discovered showing affinity to the ChHsc70 promoter in Crassostrea hongkongensis by DNA affinity purification and mass spectrometry analysis. Direct interaction between purified ChPur-α and the ChHsc70 promoter region was demonstrated by electrophoretic mobility shift assay in vitro. ChPur-α reduction led to clear enhancements of ChHsc70 transcription in the hemocytes of C. hongkongensis. Consistently, ChPur-α overexpression in heterologous HEK293T cells correlated with repressive phenotype in ChHsc70 promoter expression...
