Intraoperative variations in intra-axial brain tumor size after craniotomy: a prospective study with histopathological and tumor tissue composition correlation, introducing concepts of tumor expansion and tumor surfacing.

Intraoperative assessment of tumor margins can be challenging; as neoplastic cells may extend beyond the margins seen on preoperative imaging. Real-time intraoperative ultrasonography (IOUS) has emerged as a valuable tool for delineating tumor boundaries during surgery. However, concerns remain regarding its ability to accurately distinguish between tumor margins, peritumoral edema, and normal brain tissue.

Integrating Ni-MOF/g-CN/chitosan derived S-scheme photocatalyst for efficient visible light photodegradation of tetracycline and antibacterial activities.

Nickel MOF (Ni-MOF) nanoparticles were successfully anchored onto a polymeric graphitic carbon nitride (g-CN) and Chitosan nanostructure (NS) using an eco-friendly and straightforward synthesis method. These newly fabricated photocatalysts were thoroughly characterized with standard techniques, revealing that the nanoscale Ni-MOF particles were uniformly deposited on the sheet-like g-CN matrix. This configuration demonstrated excellent antimicrobial properties and outstanding photodegradation of tetracycline hydrochloride under visible light exposure.

Aloin reduces advanced glycation end products, decreases oxidative stress, and enhances structural stability in glycated low-density lipoprotein.

Glycation of proteins has been linked to several cardiovascular diseases, including atherosclerosis and diabetes mellitus. Various natural compounds have been explored for their anti-glycating ability. Aloin is the major anthraquinone glycoside, acquired from the Aloe species.

Discovery of novel hybrid tryptamine-rivastigmine molecules as potent AChE and BChE inhibitors exhibiting multifunctional properties for the management of Alzheimer's disease.

Contemporary research evidence has corroborated a gradual loss of central cholinergic neurons in Alzheimer's Disease (AD). This progressive deterioration leads to cognitive dysfunction and impaired motor activity, culminating in the brain cell's death in the disease. The approved drugs for AD treatment can only offer relief from symptoms without addressing the underlying pathological hallmarks of the disease.

NiFeO/g- CN modified chitosan Schiff base composite for efficient removal of Cu(II) and Hg(II) ions from the aquatic environment and its antibacterial properties.

Modification of chitosan has been achieved by the reaction of chitosan with 4- nitro-benzaldehyde via the sol-gel method, resulting in a Schiff base. A novel magnetic Graphitic Carbon Nitride/chitosan-Schiff base/NFeO (SBIV@NiFe/g-CN) adsorbent was synthesized by hydrothermal route for the adsorption of Cu(II) and Hg(II) ions from the aquatic environment. The synthesized SBIV@NiFe/g-CN was characterized using infrared spectroscopy (FT-IR), X-ray diffraction (XRD), scanning electron microscopy (SEM), vibrating sample magnetometer (VSM), and Brunauer-Emmett-Teller (BET), with a surface area of approximately 13.
