Summary
Tuberous sclerosis complex (TSC) patients may experience severe hypocalcemia, a condition linked to anticonvulsant use and kidney issues. Prompt calcium and vitamin D treatment can effectively manage this serious complication in TSC.
Area of Science:
- Nephrology
- Endocrinology
- Genetics
Background:
- Tuberous sclerosis complex (TSC) is an autosomal dominant disorder impacting multiple organs.
- Bone and mineral disturbances, including calcium homeostasis alterations, are underrecognized comorbidities in TSC.
- Hypocalcemia poses a significant risk for seizures in TSC patients.
Observation:
- This case report details a patient with TSC presenting with severe hypocalcemia.
- Potential contributing factors included anticonvulsant medication and declining kidney function.
- The patient's hypocalcemia was thoroughly evaluated, including medication history and vitamin D levels.
Findings:
- Severe hypocalcemia was identified as a critical issue in the TSC patient.
- Anticonvulsant therapy and renal impairment were suspected as contributing factors.
- Treatment involved calcium and vitamin D supplementation.
Implications:
- Highlights the importance of evaluating calcium homeostasis in TSC patients.
- Suggests a link between anticonvulsant use, kidney function, and hypocalcemia in TSC.
- Emphasizes the efficacy of calcium and vitamin D replacement therapy for managing hypocalcemia in TSC.

16.7K
Proteins can form homomeric complexes with another unit of the same protein or heteromeric complexes with different types. Most protein complexes self-assemble spontaneously via ordered pathways, while some proteins need assembly factors that guide their proper assembly. Despite the crowded intracellular environment, proteins usually interact with their correct partners and form functional complexes.

Groups of proteins may form a complex where each protein in this complex has a different role in the overall execution of the complex’s function. Often some of the proteins in the complex can be replaced by a closely related variant to give a complex that contains many of the same components yet is functionally distinct.

A type of Lewis acid-base chemistry involves the formation of a complex ion (or a coordination complex) comprising a central atom, typically a transition metal cation, surrounded by ions or molecules called ligands. These ligands can be neutral molecules like H2O or NH3, or ions such as CN− or OH−. Often, the ligands act as Lewis bases, donating a pair of electrons to the central atom. These types of Lewis acid-base reactions are examples of a broad subdiscipline called coordination...

01:09Complexation Equilibria: Factors Influencing Stability of Complexes
807
In complexation reactions, metal cations are the electron pair acceptors, and the ligands are the electron pair donors. The stability of the metal complexes depends primarily on the complexing ability of the central metal ion and the nature of the ligands. Generally, the complexing ability of the metal ion depends on the size and charge of the ion. As the metal ion size increases, the stability of the metal complexes decreases, provided that the valency of the metal ion and the ligands remain...

Power engineers have introduced the concept of complex power to determine the cumulative effect of parallel loads. This idea plays a crucial role in power analysis because it encompasses all the details related to the power consumed by a specific load.
Complex power is defined as the multiplication of the voltage and the complex conjugate of the current. The magnitude of this power, known as apparent power, is measured in volt-amperes (VA). Notably, the angle of the complex power equates to the...

Crystal Field Theory
To explain the observed behavior of transition metal complexes (such as colors), a model involving electrostatic interactions between the electrons from the ligands and the electrons in the unhybridized d orbitals of the central metal atom has been developed. This electrostatic model is crystal field theory (CFT). It helps to understand, interpret, and predict the colors, magnetic behavior, and some structures of coordination compounds of transition metals.
