Rhinoplasty patients and matched elective-surgery controls completed the Facial Appearance Sorting Test, the General Health Questionnaire, a Repertory Grid and the Masculinity/Femininity Scale. Rhinoplasty applicants perceived appearance similarly to, and downrated their own appearance to the same extent as, controls. Impaired appearance and psychiatric symptoms are integral parts of the 'rhinoplasty applicant syndrome', but the degree to which they occur is not positively correlated. Interviews and tests were repeated 6 months after operation, when marked improvement in appearance was reported by the rhinoplasty patients, associated with the reduction of psychiatric-symptom scores. Control subjects showed no change.

Background: Diabetic conditions are associated with alterations in brain functions like memory deficits through processes like synaptic dysfunction in the hippocampus. Administering a combination of silver nanonaringenin and vitamin E appears promising since they are known to prevent diabetes and memory deficits in previous studies, and nanoformulation of naringenin may be one way to improve delivery and bioavailability of naringenin in the brain. This study investigated the effects of co-administering silver nanonaringenin and vitamin E against memory deficits and synaptic dysfunction in the hippocampus of a mice model of high-fat diet and streptozotocin (HS).

The role of Natural Killer (NK) cells of the innate immune system in AD has largely been overlooked. In a murine model, depletion of NK cells augmented the accumulation of pathological α-syn.

The light-harvesting pigment-protein complex II (LHCII) from plants can be used as a component for biohybrid photovoltaic devices, acting as a photosensitizer to increase the photocurrent generated when devices are illuminated with sunlight. LHCII is effective at photon absorption in the red and blue regions of the visible spectrum, however, it has low absorption in the green region (550-650 nm). Previous studies have shown that synthetic chromophores can be used to fill this spectral gap and transfer additional energy to LHCII, but it was uncertain whether this would translate into an improved performance for photovoltaics.

Method: A randomized, double-blind, placebo-controlled crossover design was used for this trial. Participants with MCI (n = 59) were sorted into one of two sequences: Sham-tVNS or tVNS-Sham.

Background: Cognitive training and exercise intervention are suggested for enhancing cognitive functions in people with mild cognitive impairment (MCI). The use of virtual reality (VR) has been applied in cognitive training and exercise intervention in recent decades. However, it is still unclear whether VR-based intervention is a useful means to enhance cognitive functions in people with MCI.
