True Hope for Bipolar Patients ...an extensive database of biochemical data from more than 1500 patients they have treated for bipolar disorder. The PTC express their concern that many nutritional treatments offered are highly generalized and can produce unpleasant effects. Their research has found that a subgroup of bipolar disorder patients are deficient in arachidonic acid, an omega-6 fatty acid. They have developed three primary biochemical classifications of bipolar disorder as follows (written by and printed with permission of co-founder and chief-scientist of the PTC, William Walsh, PhD) 1. Undermethylation: This condition is innate & is characterized by low levels of serotonin, dopamine, and norepinephrine, high whole blood histamine and elevated absolute basophils. This population has a high incidence of seasonal allergies, OCD tendencies, perfectionism, high libido, sparse body hair, and several other characteristics. They usually respond well to methionine, SAMe, calcium, magnesium, omega-3 essential oils (DHA & EPA), B-6, inositol, and vitamins A, C, and E. They should avoid supplements containing folic acid. In severe cases involving psychosis, the dominant symptom is usually delusional thinking rather than hallucinations. They tend to speak very little & may sit motionless for extended periods. They may appear outwardly calm, but suffer from extreme internal anxiety. 2. Overmethylation: This condition is the biochemical opposite of undermethylation. It is characterized ...

Compounds for PhotoDynamic Therapy FINAL.mpg Porphyrinoids are used as photosensitizers for photodynamic therapeutic (PDT) studies. A goal is to develop high-yield reactions to append porphyrinoids with 4-8 copies of an array of biomolecules or biocompatible molecules. For example, four non-hydolysable glucose moieties on this porphyrin drives the selectivity to several breast cancer cell lines such as MDA-MB-231, and low power visible light causes both cell necrosis and apoptosis. Innovation. This work aims to developed make conjugates to porphyrinoids missing one double bond on a pyrrole (chlorin Chl), or two double bonds on adjacent pyrroles (isobacteriochlorin Ibc) or opposite pyrroles (bacteriochlorin Bc). Phthalocyanines (Pc) will be used as well. The same substitution chemistry on both of these systems should yield an array of conjugates. These conjugates will be designed to have three functionalities: (a) the R-groups impart high selectivity and greater uptake to cancer cells over normal cells, eg sugars, peptides, antibodies; (b) the photophysical properties are tunable -- for maxima absorption and formation of the triplet state for singlet oxygen sensitization; (c) the metal ion can be a radionuclide for imaging and/or therapeutics.
