Extraction and chemical characterization of humic acid produced from lignite coals of arid region of Gujarat, Western India.

In the current study, extraction of humic acid (HAs) from lignite fines of kutch basin of Gujarat (western India) were reported. The extraction was done by International Humic Substances Society (IHSS) method. Several analytical and spectroscopic techniques were used to characterize of extracted HAs.

Matrigel-encapsulated articular cartilage derived fibronectin adhesion assay derived chondroprogenitors for enhanced chondrogenic differentiation: An in vitro evaluation.

Purpose: In cartilage research, three-dimensional (3D) culture models are pivotal for assessing chondrogenic differentiation potential. Standard pellet cultures, despite their utility, pose challenges like uneven differentiation and handling difficulties. This study explores the use of Matrigel, an extracellular matrix-based hydrogel, to encapsulate fibronectin adhesion assay-derived chondroprogenitors (FAA-CPs) and evaluate their chondrogenic differentiation potential.

Waste upcycling of Sapota peels as a green route for the synthesis of silver nanoparticles and their application as catalytic and colorimetric detection of Co and Hg.

Biochemical synthesis of nanoparticles (NPs) using plant part extracts as capping and reducing agents has drawn considerable attention in research with a growing focus on green chemistry. The present study utilized Sapota (Manilkara zapota L.) peel extract to synthesize silver nanoparticles (SP-AgNPs) using ultrasonic vibration.

Predictive Role of HE4 in Diagnosis of Ovarian Tumors.

Background: Approximately 20% of women develop an ovarian cyst or pelvic mass at some point in their lives. Due to high false positivity of CA-125, women with various benign ovarian tumors simulating malignant masses undergo extensive debulking surgery resulting in increased morbidity. Serum HE4 is a useful test for better discrimination of benign or malignant nature of pelvic masses in preoperative period.
