Resolution and reproducibility in 2D gels MCQs With Answer Introduction: Two-dimensional (2D) gel electrophoresis remains a cornerstone technique in protein analysis for separating complex mixtures by isoelectric point and molecular weight. For M.Pharm students working on proteins and formulations, understanding resolution — the ability to distinguish closely related protein species — and reproducibility — the … Read more
Introduction Cilostazol is a phosphodiesterase-3 (PDE3) inhibitor used primarily for the treatment of intermittent claudication caused by peripheral arterial disease (PAD). It improves walking distance and reduces pain by promoting vasodilation and inhibiting platelet aggregation. The Mechanism of Action of Cilostazol involves inhibition of PDE3, resulting in increased cyclic adenosine monophosphate (cAMP) levels in platelets … Read more
Introduction Chlorpromazine is a first-generation (typical) antipsychotic, belonging to the phenothiazine class. It is used for schizophrenia, acute psychosis, bipolar mania, severe agitation, intractable hiccups, nausea, and tetanus-associated agitation. The Mechanism of Action of Chlorpromazine centers on dopamine D2 receptor antagonism in the mesolimbic system, along with additional blockade of histamine, muscarinic, and alpha-1 adrenergic … Read more
