Mitigation of Acrylamide in Panela: Evaluating Storage and Additive-Based Strategies on Physicochemical Properties and Sensory Quality

Abstract Panela, a traditional non-centrifugal cane sugar sweetener, undergoes intensive thermal evaporation promoting acrylamide (AA) formation through Maillard reactions. This study characterized AA formation throughout traditional panela production in Útica, Colombia, and qua...

Alternative Derivation of 3D Lorentz Transformations: Constancy of the Speed of Light from First Principles

The description of relativistic phenomena is fundamentally associated with the pioneering formulations of Hendrik Antoon Lorentz and Albert Einstein. Although extensively tested and accepted, these formulations — in our interpretation — still face several conceptual and practical...

Time-Dependent Generalized Relativistic Transformation and its Compatibility with General Relativity

With the recent proposal of the Generalized Relativistic Transformation (GRT) [1-6] — which describes any orientation of information, of velocity, and observer position in inertial relativistic events — it becomes natural to incorporate time dependence into the GRT approach. By d...

O-Glycosylated Oncofetal Fibronectin Expression in Lesions of Human Cutaneous Leishmaniasis: A Novel Finding in Infectious Diseases

Cutaneous leishmaniasis (CL) is a chronic infectious disease characterized by extensive tissue destruction and profound extracellular matrix (ECM) remodeling. This study provides the first evidence of O-glycosylated oncofetal fibronectin (onf-FN) expression in human CL lesions. I...
