Gender, gestation, and birthweight-based differences in the timing of passage of first urine and meconium in neonates: A prospective observational study.

Introduction: The cut-off for referral to a higher center and further investigations for the delayed passage of first urine and meconium by a neonate have been traditionally kept after 48 hours of birth. There are very few studies regarding this in Indian neonates, and previous studies have relied primarily on the mother's recall of the event which may have led to recall bias. Therefore, through this study, we wanted to use hospital intake/output records to identify the risk factors that affect the timing of passage of first urine and stool in neonates delivered at our center and to find out if the cut-off of 48 hours to call it a delay is justifiable.

Structural insights into IMP2 dimerization and RNA binding.

IGF2BP2 (IMP2) is an RNA-binding protein that contributes to cancer tumorigenesis and metabolic disorders. Structural studies focused on individual IMP2 domains have provided important mechanistic insights into IMP2 function; however, structural information on full-length IMP2 is lacking but necessary to understand how to target IMP2 activity in drug discovery. In this study, we investigated the behavior of full-length IMP2 and the influence of RNA binding using biophysical and structural methods including mass photometry, hydrogen-deuterium exchange coupled to mass spectrometry (HDX-MS), and small angle x-ray scattering (SAXS).

Sustainable approach of La doped CuFeO nanomaterial for electrochemical lead and paracetamol sensing action with multiple applications.

This present research aimed to investigate the novel applications of synthesized La doped CuFeO nanomaterial (LCF NMs) using renewable bio-fuel (Aegle Marmelos extract) by combustion process. The sensor applications were accomplished by modified electrode using LCF NMs with graphite powder and examined its excellent sensing action towards heavy metal (Lead content) and drug chemical (Paracetamol) substances. The thermodynamics of redox potential and super-capacitor behavior of LCF NMs were investigated through Cyclic Voltametric (CV) and Electrochemical Impedance Spectral (EIS) methods under specific conditions at scan rate of 1 to 5 mV/s.

Dipodal Silanes Greatly Stabilize Glass Surface Functionalization for DNA Microarray Synthesis and High-Throughput Biological Assays.

Glass is by far the most common substrate for biomolecular arrays, including high-throughput sequencing flow cells and microarrays. The native glass hydroxyl surface is modified by using silane chemistry to provide appropriate functional groups and reactivities for either in situ synthesis or surface immobilization of biologically or chemically synthesized biomolecules. These arrays, typically of oligonucleotides or peptides, are then subjected to long incubation times in warm aqueous buffers prior to fluorescence readout.

Global transcriptome profiling reveals root- and leaf-specific responses of barley ( L.) to HO.

In cereal crops, such as barley ( L.), the ability to appropriately respond to environmental cues is an important factor for yield stability and thus for agricultural production. Reactive oxygen species (ROS), such as hydrogen peroxide (HO), are key components of signal transduction cascades involved in plant adaptation to changing environmental conditions.

Majority had correct knowledge regarding the mode of spread of virus (n=91), safe practices (n=91) and prevention by vaccine (n=69).

Comparative analysis of stress-induced calcium signals in the crop species barley and the model plant Arabidopsis thaliana.

Background: Plants are continuously exposed to changing environmental conditions and biotic attacks that affect plant growth. In crops, the inability to respond appropriately to stress has strong detrimental effects on agricultural production and yield. Ca signalling plays a fundamental role in the response of plants to most abiotic and biotic stresses.

Organellar calcium signaling in plants: An update.

Calcium ion (Ca) is a versatile signaling transducer in all eukaryotic organisms. In plants, intracellular changes in free Ca levels act as regulators in many growth and developmental processes. Ca also mediates the cellular responses to environmental stimuli and thus plays an important role in providing stress tolerance to plants.

An octahedral geometry has been proposed for all the synthesized Co(III) and Ni(II) metal complexes.

Clinicohistopathological concordance in leprosy - a clinical, histopathological and bacteriological study of 100 cases.

Leprosy is a treatable chronic infectious disease, prevalent in South Asian countries, especially India. Before labeling a patient as a case of leprosy and starting multidrug treatment for particular type, the clinical findings should be correlated and confirmed with histopathological examination and bacteriological index of skin biopsy. Skin biopsy is an important tool in diagnosing leprosy and determining the type of leprosy.

Switchable electro-optic diffractive lens with high efficiency for ophthalmic applications.

Presbyopia is an age-related loss of accommodation of the human eye that manifests itself as inability to shift focus from distant to near objects. Assuming no refractive error, presbyopes have clear vision of distant objects; they require reading glasses for viewing near objects. Area-divided bifocal lenses are one example of a treatment for this problem.

Femtosecond pulsed laser micromachining of glass substrates with application to microfluidic devices.

We describe a technique for surface and subsurface micromachining of glass substrates by using tightly focused femtosecond laser pulses at a wavelength of 1660 nm. A salient feature of pulsed laser micromachining is its ability to drill subsurface tunnels into glass substrates. To demonstrate a potential application of this micromachining technique, we fabricate simple microfluidic structures on a glass plate.
