Evaluation of the cytotoxic and antioxidant activities Buxus wallichiana Baill leaf extract against U 87 glioblastoma.

The scientific community has been drawn towards natural plant resources due to the rising success rates. This work aimed to explore the phytochemical, antioxidant and anti-cancer properties of an ethanolic extract derived from the leaves of Buxus wallichiana Baill. which is utilized in traditional medicine in the treatment of various disease such as respiratory disorders, GI disorders and inflammation.

Neurogenin-2 induced neuronal differentiation in co-cultured bone marrow stromal and neonatal cortical cells.

Objective: To explore a novel and dynamic role for neurogenin-2 in promoting cortical neurogenesis in cells produced from co-culturing neonatal cortical neural progenitor cells with bone marrow stromal cells.

Methods: The experimental study was conducted from June 2016 to January 2019 at the neuropharmacology laboratory of the Hussein Ebrahim Jamal Research Institute of Chemistry, International Centre for Chemical and Biological Sciences, Karachi. The growth of cells at different stages in harvested cells was determined by 3-(4, 5- dimethyl thiazol-2-yl)-2, 5-diphenyl tetrazolium bromide assay.

Memory and cognition enhancing effects of combination of Melissa officinalis and Panax ginseng.

Melissa officinalis and Panax ginseng extracts were investigated to determine combinatorial effects on cognitive behaviors' of albino-rats. The study was prospective-experimental; lasted from June-2022 to March-2023. Learning and memory measurements were done by animal-models.

Unravelling the enigma of siRNA and aptamer mediated therapies against pancreatic cancer.

Pancreatic cancer (PC) is a fatal disease that has a poor 5-year survival rate. The poor prognosis can be attributed to both troublesome detections at the initial stage, which makes the majority of the treatment options largely unsuccessful and leads to extensive metastasis, as well as to its distinct pathophysiological characteristics, such as rich desmoplastic tumours bounded by dysplastic and hypo perfused vessels restricting the mobility of therapeutic agents. Continued attempts have been made to utilise innovative measures for battling PC to increase the therapeutic effectiveness of therapies and overcome their cytotoxicity.

Highly potent anti-inflammatory, analgesic and antioxidant activities of 3,5-disubstituted tetrahydro-2H-1,3,5-thiadiazine thiones.

Four series of tetrahydro-2H-1,3,5-thiadiazine-2-thiones (series A and B including two novel enantiopure isomers), tetrahydro-2H-1,3,5-thiadiazine-6-thiones (series C) and N-3 ester derivatives of tetrahydro-2H-1,3,5-thiadiazine-6-thiones (series D) were synthesized and evaluated for their anti-inflammatory, analgesic and anti-oxidant activities. These THTT analogues specially series D were first time examined for their in vitro anti-inflammatory, in vivo analgesic and anti-oxidant activities. Among them lipophilic compounds (series B and D) were found to be highly active for anti-inflammatory evaluation with IC values between 5.

Lipid-based nanocarrier mediated CRISPR/Cas9 delivery for cancer therapy.

CRISPR/Cas mediated gene-editing has opened new avenues for therapies that show great potential for treating or curing cancers, genetic disorders, and microbial infections such as HIV. CRISPR/Cas9 tool is highly efficacious in revolutionizing the advent of genome editing; however, its efficient and safe delivery is a major hurdle due to its cellular impermeability and instability. Nano vectors could be explored to scale up the safe and effective delivery of CRISPR/Cas9.

Neuronal transcription program induced in hippocampal cells cocultured with bone marrow derived mesenchymal cells.

Several approaches have been applied to harvest bone marrow stromal cells (BMSCs) and to differentiate into neurons or neuronal-like cells through chemical stimulation or exposing to growth factors. To date, the data regarding induction or regulation of neuronal transcription program in neuronal-like cells derived from BMSCs is yet unknown. The objective of this study is to co-culture BMSCs with neonatal hippocampal cells and generate neuronal-like cells by direct cell-to-cell contact system without using neuronal growth factors or neurobasal medium.

Chitosan‑zinc sulfide nanoparticles, characterization and their photocatalytic degradation efficiency for azo dyes.

Herein, chitosan‑zinc sulfide nanoparticles (CS-ZnS-NPs) were developed as an efficient photocatalyst for the degradation of toxic dyes. The as-synthesized CS-ZnS-NPs were analyzed using XRD, FTIR, SEM, and EDS. The functional groups of CS-ZnS-NPs were validated with FTIR spectroscopy.

N-(2-hydroxyphenyl) acetamide (NA-2) elicits potent antitumor effect against human breast cancer cell line (MCF-7).

Breast cancer is the most dominating malignancy in females worldwide. Treatment with conventional chemotherapeutics is associated with severe adverse effects. Thus need of new compounds, with better therapeutic potential and lesser side effects still exist.

Design and synthesis of mixed micellar system for enhanced anticancer efficacy of Paclitaxel through its co-delivery with Naringin.

Emergence of multidrug resistance (MDR) has limited the success of chemotherapeutic agents. Reversal of drugs efflux systems through combination therapy has got wider attention for increasing anticancer drugs efficacy. This study aims at co-encapsulation of Paclitaxel with Naringin in mixed polymeric micelles for enhanced anticancer activity of the drug.
