Article Synopsis
  • The study aimed to determine how acupuncture affects serum gastrin levels and urinary sodium excretion in spontaneously hypertensive rats (SHRs) to investigate its potential as a treatment for hypertension.
  • Thirty-two male SHRs were divided into four groups (model, hydrochlorothiazide, acupuncture, and sham acupuncture) to compare the effects of acupuncture and a diuretic over a 4-week period, measuring changes in blood pressure, urine volume, and renal tissue health.
  • Results indicated that while blood pressure was significantly higher in the model group compared to controls, both acupuncture and hydrochlorothiazide helped improve urinary function and potentially influenced pathways related to sodium handling in the kidneys.

Article Synopsis
  • - Propyl gallate (PG) is a common antioxidant used in food, cosmetics, and pharmaceuticals, but recent studies indicate it may negatively affect reproductive health in humans and animals, specifically oocyte (egg) quality.
  • - Research on mice demonstrated that PG exposure disrupts oocyte meiosis by causing mitochondrial stress, leading to apoptosis (cell death) and significant DNA damage, which can halt oocyte development.
  • - The study also found that PG exposure increases levels of reactive oxygen species (ROS) and alters histone methylation, further contributing to the impairment of oocyte maturation.

Cues associated with alcohol use can readily enhance self-reported cravings for alcohol, which increases the likelihood of reusing alcohol. Understanding the neuronal mechanisms involved in alcohol-seeking behavior is important for developing strategies to treat alcohol use disorder. In all experiments, adult female alcohol-preferring (P) rats were exposed to three conditioned odor cues; CS+ associated with EtOH self-administration, CS- associated with the absence of EtOH (extinction training), and a CS a neutral stimulus.

Previous studies indicated that cotinine, the major metabolite of nicotine, supported intravenous self-administration and exhibited relapse-like drug-seeking behaviors in rats. Subsequent studies started to reveal an important role of the mesolimbic dopamine system in cotinine's effects. Passive administration of cotinine elevated extracellular dopamine levels in the nucleus accumbens (NAC) and the D1 receptor antagonist SCH23390 attenuated cotinine self-administration.

  • Triclocarban (TCC) is a widely used antibacterial agent that is harmful to the environment and can accumulate in the human body through various exposures, leading to concerns about its safety and reproductive toxicity.
  • Research on the impact of TCC on early embryonic development in mice revealed that it affects development in a dose-dependent manner, with thousands of genes being differentially expressed, particularly impacting processes like redox reactions and DNA damage.
  • TCC exposure increased DNA methylation and altered histone modifications, causing oxidative stress and ultimately disrupting zygotic genome activation and the degradation of maternal genes in 2-cell embryos.

As a major public health achievement, disinfection of drinking water significantly decreases outbreaks of waterborne disease, but produces drinking water disinfection by-products (DBPs) unfortunately. The haloacetic acids (HAAs) including bromoacetic acid (BAA), the second major class of DBPs, are considered as a global public health concern. BAA has been identified as cytotoxic, genotoxic, mutagenic, carcinogenic, and teratogenic in somatic cells.

With the substantial social and medical burden of addiction, there is considerable interest in understanding risk factors that increase the development of addiction. A key feature of alcohol use disorder (AUD) is compulsive alcohol (EtOH) drinking, where EtOH drinking becomes “inflexible” after chronic intake, and animals, such as humans with AUD, continue drinking despite aversive consequences. Further, since there is a heritable component to AUD risk, some work has focused on genetically-selected, EtOH-preferring rodents, which could help uncover critical mechanisms driving pathological intake.
