The high cost of mAbs also prevents it from being a more common therapeutic method for treating maladies. These costs can be attributed to the multiple large doses that must be administered intravenously at regular intervals in order to maintain systemic volumes of distribution. Therefore‚ it is beneficial to explore an alternative method of delivery that can sustain delivery of mAbs in its therapeutic window for long periods of time. Oral antibody dosing shows almost zero bioavailability. Intravenous

can have a little of what you fancy without causing major disruption to your body. The right combination of carbohydrates‚ protein and fat eaten at regular intervals will help keep energy levels high. 2. Increase Protein: Eating healthy high protein snacks will help keep your blood-sugar levels even so that you don’t have energy ’highs’ and ’lows’. Aim for half protein & half carb per snack...Ie: Cashew Butter & Celery‚ Houmous & Cucumber‚ Ham & Melon or Fruit & natural nuts & seeds are just

The tert-butyl group has been broadly used to protect functional groups in natural product synthesis such as amino acid‚ peptide and protein chemistry [1]. The tert-butoxycarbonyl (BOC) group is known as protecting group for amides in organic synthesis. The introduction of BOC group improves the solubility of organic precursors and their processability in organic synthesizes [2]. The methyl substituted pyridine derivatives were widely reported for their various biological activities such as anxiolytic
