Aim: The present study investigated whether intraperitoneal treatment with the herbal formula B210 ([B210]; a herbal composition of and ) can reduce snoring in aged rats. Also, we studied possible neural mechanisms involved in B210 treatment and subsequent reduced snoring in rats.
Methods And Result: We compared pressure and frequency of snoring, activities of phrenic nerve (PNA), activities of recurrent laryngeal nerve (RLNA) and activities of hypoglossal nerve (HNA), inspiratory time (T) and expiratory time (T) of PNA, and pre-inspiratory time (Pre-T) of HNA in aged rats between sham and B210 treatment groups (30 mg/mL dissolved in DMSO). We found that aged rats that received B210 treatment had significantly reduced pressure and frequency of snoring than rats who received sham treatment. Also, we observed that aged rats that received B210 treatment had significantly increased PNA, RLNA, and HNA, extended T and T of PNA, and prolonged Pre-T of HNA compared to rats that received sham treatment. In other words, B210 treatment may relieve snoring through modulating activities and breathing time of upper airway related nerves in aged rats.
Conclusion: We suggested that the B210 might be a potential herbal formula for snoring remission.

Background: Obesity and metabolic syndrome are major public health concerns linked to cognitive decline with aging. Prior work from our lab has demonstrated that short-term high fat diet (HFD) rapidly impairs memory function via a neuroinflammatory mechanism. However, the degree to which these rapid inflammatory changes are unique to the brain is unknown.

Seizures elicited by corneal 6-Hz stimulation are widely acknowledged as a model of temporal lobe seizures. Despite the intensive research in rodents, no studies hint at this model in developing animals. We focused on seven age groups of both male and female rats.

Background: Our previous studies reported that D-galactose (D-gal) administration for four to eight weeks caused metabolic disturbance, brain mitochondrial dysfunction, and brain aging, leading to cognitive dysfunction in similar with natural aging condition. Spermidine is a polyamine that can be found naturally. Spermidine has been showed the beneficial effects on various models, such as attenuating metabolic/gut impairments in obesity, and ameliorating memory loss in aged model.

Background: Clinical studies indicate that mid-life dietary patterns are a risk factor for cognitive decline. Adherence to a Mediterranean diet (MeDi) may promote healthy brain aging in contrast to a Western diet (WD), yet these diets have not been examined in pre-clinical models. We hypothesized that consumption of the MeDi would have better cognitive performance compared to the Western diet in middle-aged rats.

Background: The orexin/hypocretin neuropeptide system, primarily found in the lateral hypothalamus and perifornical region, modulates sleep, wakefulness, appetite, and cognitive function. One region with dense orexinergic projections is the basal forebrain (BF), which is the major source of acetylcholine in the neocortex and limbic structures such as the hippocampus. The basal forebrain cholinergic system mediates cognition and dysfunction is one of the key hallmarks of Alzheimer's disease.
