Epigenetic Changes Caused by Occupational Stress in Humans Revealed through Noninvasive Assessment of DNA Methylation of the Tyrosine Hydroxylase Gene
Tyrosine hydroxylase (TH) catalyzes the rate-limiting step in the synthesis of L-dihydroxyphenylalanine (L-DOPA), a precursor of dopamine, and is considered to be involved in many aspects of mental health. On the other hand, the epigenetic mechanisms have been recognized as mediators of stable changes in brain function.
Methamphetamine is one of the most commonly abused illegal stimulants and causes the release of dopamine, norepinephrine and serotonin. These neurotransmitters trigger vasospasm, causing persistent tachycardia, hypertension, and direct myocardial toxicity. Moderate usage of methamphetamine can increase cardiac output and myocardial contractility. However, larger doses can cause depression of the myocardium.
Acute Type C Botulism with Fatal Consequences in a Holstein Breeding Establishment in Northern Italy
BOTULISM is a neuro-paralytic intoxication illness caused by the ingestion of neurotoxins of Clostridium botulinum with contaminated water or food. The Gram-positive spore-producing bacterium Cl. botulinum is found worldwide and can survive in spore form for up to 30 years in numerous substrates in the environment. Cl. botulinum is classified into 7 or 8 different types (A, B, C (C1, C2), D, E, F, G) depending on the antigen properties of the botulinum neurotoxins (BoNT) produced, with intoxication mostly appearing in cattle following the ingestion of neurotoxins of type C and D and, less frequently, of type B.
Folic Acid Supplementation Reduced Depression Score in Young Japanese Women with Depression-susceptible Genetic Polymorphisms
Background: Observational studies have shown that low folate status induces depression. Here we studied the effects of folic acid supplementation on depression scores of Japanese women with depression-susceptible gene polymorphisms: methylenetetrahydrofolate reductase (MTHFR), serotonin transporter (5-HTT), and dopamine D4 receptor (DRD4).
