Cissus quadrangularis mediated biogenic synthesis of silver-nanohydroxyapatite-mesoporous silica nanocomposite, characterization, and cytotoxicity evaluation on dental pulp stem cells.

This study focuses on tripartite synthesis of Silver (AgNPs), Mesoporous Silica (MSNs), and Hydroxyapatite (n-HAp) nanoparticles with aqueous extract of Cissus quadrangularis (Veldt grape plant; Indian name: Pirandai) as a reducing agent. The dried and powdered form of the plant was subjected to aqueous extraction. The phytochemicals analysis was qualitatively estimated which detected the presence of alkaloid, tannin, phenol, terpenoid, steroid and saponin.

Photoinduced Immobilization on Two-Dimensional Nano Borophene Spatially Orients Capture Antibody for Highly Sensitive Biological Interactions.

Two-dimensional (2D) nanomaterials are of great interest due to their unique properties and broad biological applications. Among these, borophene, a single-atom-thick boron sheet with a honeycomb structure, exhibits exceptional structural, electronic, and mechanical characteristics, making it a promising candidate for sensing, electronics, and biosensing. In this study, we report on a liquid-phase exfoliation method to synthesize stable borophene nanosheets and introduce a photoinduced immobilization technique to functionalize their surfaces with antibodies.

Ultrasound-Guided Peripheral Nerve Block for Emergency Below-Knee Amputation in a High-Risk Patient With Coagulopathy: A Case Report.

Emergency below-knee amputation (BKA) in patients with significant comorbidities and coagulopathy presents formidable anesthetic challenges, as a central neuraxial blockade and general anesthesia are frequently contraindicated. We report the case of a 57-year-old female patient with uncontrolled diabetes mellitus, chronic kidney disease, coronary artery disease, and an elevated international normalized ratio (INR) of 1.6, necessitating urgent BKA for a septic diabetic foot ulcer.

A rare case of precursor B-cell lymphoblastic lymphoma of the orbit in a child.

A 5-year-old boy presented with gradually progressive painful proptosis of the left eye for 5 months. He had an incidental testicular swelling for which he underwent high inguinal orchidectomy and histopathology showed atypical lymphoid cells. His vision was 6/6, N6 in the right eye, and no perception of light in the left eye.

Green synthesis of silver nanoparticles using with 0.1% of thymoquinone and evaluation of its anti-inflammatory and antioxidant activities - An study.

Background: The therapeutic potential of herbs in treating various diseases is gaining recognition due to their promising outcomes and minimal side effects. One such herb, , is renowned for its medicinal properties, particularly due to its extract, Thymoquinone (TQ), which demonstrates anti-inflammatory, anti-oxidant, antimicrobial, analgesic, and immune-modulating effects. Green synthesis methods for nano-sized particles are considered environmentally friendly and have been proven effective given their size, higher surface-to-volume ratio, and enhanced physical and mechanical properties.
