Kaixin-San (KXS), a Chinese formula, was used to treat "amnesia", a senile dementia in the modern world. This formula was reported to improve behavioral performances in many animal models. This study was designed to explore how KXS has improved amyloid-β (Aβ)-induced memory dysfunction in mice. The mouse models were achieved through unilateral ventricle injection with Aβ42. The effects of KXS on memory improvement was evaluated by step-down test. The electrophysiological changes induced by KXS were measured by long-term potentiation (LTP) analysis in the hippocampus in vivo...

Ageing causes the degeneration of organs of the locomotor system, including the cerebellum and bones. Exercise may reverse this deterioration. D-galactose has been frequently used in rodents to accelerate ageing. The present study aimed at investigating the effects of exercise on cerebellar and serum growth factors, motor activity, and the number of bone cells of the femoral head of D-galactose-treated rats. Twenty-four male Wistar rats were divided randomly into four groups, i.e. three treated groups injected with 300 mg/ml/kg bw D-galactose solution daily for 4 weeks, and a control group injected with normal saline...

Treadmills are often employed as rehabilitation devices to improve gait in Parkinson's disease (PD). Kinematic differences between treadmill and overground gait have been reported. However, electromyographic (EMG) patterns during treadmill and overground walking have not been systematically compared. The aim of this study was to assess the effects of treadmill gait on the magnitude of the EMG activity of the lower limb muscles in PD. We measured EMG activity of the tibialis anterior (TA), gastrocnemius medialis (GM), vastus lateralis (VL) and biceps femoris (BF) of 9 individuals with PD and 9 healthy matched controls...

OBJECTIVE: Pulp regeneration by stem cell transplantation declines due to age-related reduction in proliferation, migration and anti-apoptotic activities of surrounding tissue-derived resident stem cells. We hypothesized that administration of a cytokine together with the cell transplantation may improve the stem cell niche microenvironment and promote regeneration. CCL11/Eotaxin is implicated as a factor in aging. This investigation was performed to investigate the changes in the quality and quantity of the regenerated pulp by administration of CCL11 antibody in the aged mice and elucidate the underlying mechanisms...

Brain aging is an intricate and natural phenomenon exclusively characterized by oxidative stress, accumulation of oxidatively damaged macromolecules, and alterations in structure and function of neurons that further increase the risk factor for most of the neurodegenerative diseases. In addition, age-dependent defective autophagy has also been implicated to favour the pathogenesis and prevalence of the neurological diseases. Therefore, the development of strategies that delay aging and the concomitant neurological disorders remain elusive...

Chronic inflammation is a major driving factor for the development of colitis-associated cancer (CAC). It is extensively acknowledged that patients who have long-standing inflammation bowel disease (IBD) are at high risk for developing CAC. However, the metabolic alteration by which chronic intestinal inflammation promotes colorectal cancer is unclear. In the present study, we constructed dextran sulfate sodium (DSS)-induced chronic colitis mouse model to uncover possible alterations in the metabolism indexes...

We examine self-experimentation ethics history and practice, related law, use scenarios in universities and industry, and attitudes. We show through analysis of the historical development of medical ethics and regulation, from Hippocrates through Good Clinical Practice that there are no ethical barriers to self-experimentation. When the self-experimenter is a true investigator, there is no other party to be protected from unethical behavior. We discuss the n-of-1 issue in self-experiments, and make suggestions for improving experiment design...

Objective of this study was to determine whether the prepared nanoemulsion would be able to deliver selegiline to the brain by intranasal route, improving its bioavailability. Antioxidant activity, pharmacokinetic parameters, and dopamine concentration were determined. Oxidative stress models, which had Parkinson's disease-like symptoms, were used to evaluate the antioxidant activity of nanoemulsion loaded with selegiline in vivo. The antioxidant activity was evaluated by 1,1-diphenyl-2-picryl-hydrazyl (DPPH) assay and reducing power assay, which showed high scavenging efficiency for selegiline nanoemulsion compared to pure selegiline...

The ideal perioral and lip rejuvenation technique provides the longest period of efficacy, lowest complication rate, and best aesthetic results. Genetics, intrinsic aging, sun exposure and repetitive muscle twitching of the orbicularis oris produce angular, radial, and vertical lines of the perioral lines and, for this reason, the needs of patients in the treatment of this anatomical area can range from simple lip enhancement to a broader and more comprehensive treatment with simultaneous correction of perioral wrinkles...

Proteostasis, which includes the repair and disposal of misfolded proteins, depends, in part, on the activity of heat shock proteins (HSPs), a well-known class of chaperone molecules. When this process fails, abnormally folded proteins may accumulate in cells, tissues, and blood. These species are a hallmark of protein aggregation diseases, but also amass during aging, often in the absence of an identified clinical disorder. We report that a neuroprotective cyclic heptapeptide, CHEC-7, which has been applied systemically as a therapeutic in animal neurodegeneration models, disrupts such aggregates and inhibits amyloidogenesis when added in nanomolar concentrations to human plasma...

Atherosclerotic cardiovascular disease, including peripheral artery disease (PAD), is more common and severe in diabetic patients compared with nondiabetic individuals. Indeed, diabetes is associated with the increased risk of limb amputation and all-cause mortality in patients with symptomatic PAD. Proteins and lipids are nonenzymatically modified by sugars, resulting in the formation and accumulation of advanced glycation end products (AGEs), whose process is accelerated under diabetic conditions, especially patients with a long duration of diabetes...

The hypothesis regarding the role of increased nicotinamide adenine dinucleotide (NAD+) levels with reference to the fundamental concepts of ageing and entropy is presented. Considering the second law of thermodynamics, NAD+ seems the appropriate candidate for reversing many aging-associated pathologies. NAD+ is presented as an essential compound that enables organisms to stay highly organized and well-maintained, with a lower entropy state.
