Commonly linked with cosmetic uses, Botox is the trade name for botulinum toxin
Interestingly, the premature stop codon of two transcripts ( DEFA35L , DEFA36L ) is at the same position as that observed for the -defensin precursors involved in the assembling of cyclic -defensins [126] and may indicate an existence of -defensins outside primates [41]
In some cases, injections are paused to monitor natural absorption or due to changing medical needs, not because B12 is unsafe
Conditions include alcoholic liver disease, viral hepatitis, cirrhosis, and primary or metastatic liver cancer Renal dysfunction : Impaired kidney function reduces B12 elimination, causing accumulation even with normal intake Haematological conditions : Myeloproliferative neoplasms, chronic myeloid leukaemia, polycythaemia vera, and hypereosinophilic syndrome increase transcobalamin production, elevating total serum B12 Laboratory interference : Macro-B12 (immunoglobulin-bound B12) and assay interference can cause spuriously elevated results without true excess In clinical practice, unexplained hypercobalaminaemia should prompt investigation for underlying disease, particularly in patients without obvious supplementation history
