Article Synopsis
  • The study investigates the effects of neodymium (Nd), a rare earth element, on the mussel species Mytilus galloprovincialis when exposed to the toxic phytoplankton Gymnodinum catenatum over a 28-day period.
  • Results indicated that mussels accumulated similar toxins whether exposed solely to G. catenatum or in combination with Nd, while Nd exposure inhibited enzyme activity and caused cellular damage.
  • The research highlights that the combined presence of Nd and harmful algal blooms can lead to unexpected biochemical responses in marine organisms, suggesting that multiple environmental stressors can significantly influence marine life and ecosystem health.

Article Synopsis
  • The study evaluated the biological activity and bioactive compounds in different sea cucumber species and various tissues like intestine, muscle band, and gonads.
  • One species showed the lowest levels of phenolic compounds and antioxidant activity, while another species had the highest phenolic concentration in the respiratory tree.
  • The research found that the biomass exhibited varying levels of anti-inflammatory activity, with the respiratory tree having the most significant effects, indicating potential for future applications in biorefinery.

Bone metabolic disorders such as osteoporosis are characterized by the loss of mineral from the bone tissue leading to its structural weakening and increased susceptibility to fractures. A growing body of evidence suggests that inflammation and oxidative stress play an important role in the pathophysiological processes involved in the rise of these conditions. As the currently available therapeutic strategies are often characterized by toxic effects associated with their long-term use, natural antioxidants and anti-inflammatory compounds such as polyphenols promise to be a valuable alternative for the prevention and treatment of these disorders.

The effects of alcohol abuse on HIV disease progression have not been definitively established. A prospective, 30-month, longitudinal study of 231 HIV(+) adults included history of alcohol and illicit drug use, adherence to antiretroviral therapy (ART), CD4(+) cell count, and HIV viral load every 6 months. Frequent alcohol users (two or more drinks daily) were 2.

Background: Adequate zinc is critical for immune function; however, zinc deficiency occurs in >50% of human immunodeficiency virus (HIV)-infected adults. We examined the safety and efficacy of long-term zinc supplementation in relation to HIV disease progression.

Methods: A prospective, randomized, controlled clinical trial was conducted involving 231 HIV-infected adults with low plasma zinc levels (<0.

Background: HIV infection is prevalent among substance abusers. The effects of specific illicit drugs on HIV disease progression have not been established. We evaluated the relationship between substances of abuse and HIV disease progression in a cohort of HIV-1-positive active drug users.

HIV/HCV co-infection is becoming one of the main causes of death in HIV+ persons. We determined quality of life, clinical symptoms and health care utilization in HIV mono-infected and HIV/HCV co-infected chronic drug users. After consenting 218 HIV+ drug users, a physical examination and questionnaires on demographics, quality of life, drugs of abuse, and healthcare utilization were completed.

The frequency of coronary heart disease (CHD) is increasing among HIV seropositive persons. This phenomenon may be related to HIV disease itself, the use of antiretroviral medications and increased length of survival, or the synergism of these factors. In this study we have calculated the 10-year CHD risk estimate and the prevalence of metabolic syndrome in a cohort of 118 HIV seropositive chronic drug users, including those who are on HAART with or without protease inhibitors (PI).

Background: A decrease in the rate of human immunodeficiency virus (HIV) infection-related wasting has been reported in the era of highly active antiretroviral therapy (HAART). We investigated this concern in a hard-to-reach population of HIV-infected drug users in Miami, Florida.

Methods: After informed consent was obtained, 119 HIV-infected drug users were administered questionnaires involving demographic, medical history, and food-security information.
