Development of an ultrasensitive sensor for detecting metol in environmental water samples using ruddlesden-popper type layered perovskite (LaNiO) combined with graphene oxide.

Metol (MTO), a commonly used photographic developer, has become an environmental pollutant due to its extensive use and subsequent release into water sources. The accumulation of MTO poses significant risks, including aquatic toxicity and potential bioaccumulation, leading to adverse effects on ecosystems. To address these environmental challenges, we developed a La₂NiO combined with graphene oxide (La₂NiO₄@GO) nanocomposite modified glassy carbon electrode (GCE) for the ultrasensitive detection of MTO.

Splenic B-cell lymphoma/leukemia with prominent nucleoli: A three-case series of the newly named old entity and review of literature.

Context: Splenic B-cell lymphoma/leukemia with prominent nucleoli (SBLPN) aka hairy cell leukemia variant (HCL-v) is a rare B-cell chronic lymphoproliferative disorder. The main diagnostic challenge is to differentiate SBLPN from Classical hairy cell leukemia (HCL-c), as the former faces inferior responses to therapies and a poor prognosis.

Aims: The aim is to discuss the clinic-hematological and immunophenotyping findings of three cases of SBLPN.

Extraction and characterization of natural lignocellulosic fibres from Typha angustata grass.

In recent years, efforts have been made to reduce deforestation to conserve the ecosystem. In the current scenario, agro-cultivated products are used instead of wood for engineering applications. Thus, natural lignocellulosic fibres are used as a reinforcing material and have been extremely attractive to industries and the scientific community during the past few decades.

Prioritizing the candidate genes related to cervical cancer using the moment of inertia tensor.

It is well known that cervical cancer poses the fourth most malignancy threat to women worldwide among all cancer types. There is a tremendous improvement in realizing the underlying molecular associations in cervical cancer. Several studies reported pieces of evidence for the involvement of various genes in the disease progression.

Multifractal and cross-correlation analysis on mitochondrial genome sequences using chaos game representation.

We characterized the multifractality and power-law cross-correlation of mitochondrial genomes of various species through the recently developed method which combines the chaos game representation theory and 2D-multifractal detrended cross-correlation analysis. In the present paper, we analyzed 32 mitochondrial genomes of different species and the obtained results show that all the analyzed data exhibit multifractal nature and power-law cross-correlation behaviour. Further, we performed a cluster analysis from the calculated scaling exponents to identify the class affiliation and its outcome is represented as a dendrogram.

A graph centrality-based approach for candidate gene prediction for type 1 diabetes.

Type 1 diabetes mellitus (T1DM) or insulin-dependent diabetes is an autoimmune disease that may pose life-threatening situations to individuals. In most cases, cytotoxic T lymphocytes (CTLs) promotes killing of islets of Langerhans in the pancreas, which harbour insulin-producing beta cells. The trigger for autoimmune attack is still unclear; therefore, identifying and targeting candidate genes are imperative to hinder its deleterious effects.

Synthesis, Spectral Characterization and Biological Activities of Co(II) and Ni(II) Mixed Ligand Complexes.

2,4-Dinitrophynylhydrazine and two thiocyanate ions in a (M:L1:L2) 1:2:2 molar ratio was synthesized in the complexes of Co(II) and Ni(II). The prepared compounds were identified through a C.H.

Rare cause of extravasation from implantable venous access device.

Implantable venous access devices are routinely used, but they are not without complications. A 4-year-old male child with B cell acute lymphoblastic leukaemia was planned for chemotherapy. Chemo port was accessed through the right internal jugular vein.

Comparative Evaluation of Implant Designs: Influence of Diameter, Length, and Taper on Stress and Strain in the Mandibular Segment-A Three-Dimensional Finite Element Analysis.

Introduction: Success or failure of dental implants depends on the amount of stress transferred to the surrounding bone. Increased amount of loading to the bone through implant cause failure, whereas decrease in the amount of loading to the bone causes improved success rate of implants. Biomechanical interaction between implant and bone decides the long-term function or prognosis of dental implant system.
