  1. Toxoplasmosis can be a sexually transmitted infection with serious clinical consequences. Not all routes of infection are created equal.

    Medical Hypotheses 83(3):286 (2014) PMID 24986706

    We present a hypothesis suggesting that toxoplasmosis is transmitted from infected men to noninfected women during unprotected sexual intercourse, which can result in the most serious form of disease, congenital toxoplasmosis. Arguments for the hypothesis: (1) Toxoplasma tachyzoites are present in t...
  2. Helicobacter pylori might be a potential therapeutic target in epilepsy.

    Medical Hypotheses 76(5):763 (2011) PMID 21356577

  3. Glucomannan minimizes the postprandial insulin surge: a potential adjuvant for hepatothermic therapy

    Medical Hypotheses 58(6):4 (2002)

  4. Oxycodone recycling: A novel hypothesis of opioid tolerance development in humans.

    Medical Hypotheses 83(3):326 (2014) PMID 24986643

    We hypothesize that oxycodone (OC) recycling promotes sustained synaptic OC content, which prolongs OC's exposure to local μ-opioid receptors (μORs). In that way, OC recycling gives rise to OC tolerance in humans. To pilot test our hypothesis, we developed a whole-body OC mass transport tolerance re...
  5. Salmonella as a biological "Trojan horse" for neoplasia: Future possibilities including brain cancer.

    Medical Hypotheses 83(3):343 (2014) PMID 24986645

    This manuscript considers available evidence that a specific Salmonella strain could be used as an effective orally-administered option for cancer therapy involving the brain. It has been established that Salmonella preferentially colonizes neoplastic tissue and thrives as a facultative anaerobe in...
  6. CCNB1 is a prognostic biomarker for ER+ breast cancer.

    Medical Hypotheses 83(3):359 (2014) PMID 25044212

    We demonstrated that CCNB1 had significant predictive power in distant metastasis free survival, disease free survival, recurrence free survival and overall survival of ER+ breast cancer patients. We also found that CCNB1 was closely associated with hormone therapy resistance. In addition, gene set...
  7. Prostaglandins in semen compromise the immune response against sexually transmitted pathogens.

    Medical Hypotheses 83(2):208 (2014) PMID 24837236

    We have recently shown that exposure to seminal plasma induces the differentiation of dendritic cells into a tolerogenic profile through a mechanism dependent on the activation of the prostanoid receptors EP2 and EP4 by seminal PGE. Our hypothesis proposes that this tolerogenic response induced by s...
  8. Benefits of the povidone-iodine: simultaneously decrease risk of infection and tumor seeding after percutaneous endoscopic gastrostomy.

    Medical Hypotheses 82(6):678 (2014) PMID 24650418

    Percutaneous endoscopic gastrostomy (PEG) is a well-established enteral feeding modality in patients with oropharyngeal/esophageal cancer; however, these patients are at risk for two possible PEG-related complications. First, oropharyngeal organisms may be transported to the PEG stoma and thus incre...
  9. Low dietary sodium in diabetes nephropathy.

    Medical Hypotheses 82(5):551 (2014) PMID 24581676

    We hypothesise that in diabetic nephropathy, ACE-I or ARB treatment attenuates any rise in RAS hormones that might result from dietary salt restriction and that the beneficial effects of the salt restriction such as a lower blood pressure outweigh any potentially negative consequences of RAS activat...
  10. The putative role of proteolytic pathways in the pathogenesis of Type 1 diabetes mellitus: the 'autophagy' hypothesis.

    Medical Hypotheses 82(5):553 (2014) PMID 24582332

    I and class II self-antigen presentation at the basis of the autoimmunity process. Furthermore cross-talk among different proteolytic pathways was recently highlighted i.e. components processed in the ubiquitin/proteasome system possibly engaged in autophagic pathways. T1D is an autoimmune disease c...
