An individual shows handedness when they consistently prefer one hand over the other for tasks that can be performed with either hand. Humans have a population-level right-hand preference, and past research shows that a variety of nonhuman primate species also show hand preferences. More complex manual tasks elicit stronger hand preferences than less complex manual tasks, but not much is known about hand preferences during a cognitive task in nonhuman primates.

HMGB1 is a key late inflammatory mediator upregulated during air-pollution-induced oxidative stress. Extracellular HMGB1 accumulation in the airways and lungs plays a significant role in the pathogenesis of inflammatory lung injury. Decreasing extracellular HMBG1 levels may restore innate immune cell functions to protect the lungs from harmful injuries.

UP165, a standardized (corn) leaf extract, was evaluated for its effect on sleep quality and overall well-being in a double-blind, placebo-controlled clinical trial, administered orally at 250 and 500 mg/day. Participants ( = 45) (age range 19-73) consumed the supplement or placebo ∼60 minutes before bedtime daily for 4 weeks. Measurements that were evaluated were as follows: daily sleep quality, as monitored by a fitness tracker; the Pittsburgh Sleep Quality Index (PSQI) for sleep quality and efficiency; salivary cortisol levels for stress; and Profile of Mood States (POMS) to assess general well-being.

Acne vulgaris is a common skin disease that manifests clinically as comedones, papules, nodules, and cysts. In this single center, open-label pilot study (ISRCTN13992386), we aimed to evaluate the effectiveness of UP256 cream, a newly patented topical product containing 0.5% bakuchiol, on facial acne and acne-related post-inflammatory hyperpigmentation (PIH).

Symptom-alleviating therapies for osteoarthritis (OA) management are inadequate. Long-term application of first-line treatments, such as nonsteroidal anti-inflammatory drugs, is limited due to associated side effects. We believe that a combination of traditionally used botanical extracts, which have diverse active components that target multiple inflammatory pathways, may provide a safe and efficacious alternative to address the multifactorial nature of OA.
