Modelling and experimental studies on mass transport of multiple cryoprotective agents in articular cartilage.

Cartilage transplantation is an effective way to repair, reconstruct, and replace damaged articular cartilage (AC) but its use is limited by the inability to preserve AC for long periods of time. Vitrification is an ideal choice for long-term storage of AC, and multiple cryoprotective agents (CPAs) with high concentration are usually used. To obtain high cell viability, chondrocytes at all locations inside AC should be protected properly by the CPAs during cooling and rewarming.

Fluorene-9-bisphenol exposure decreases locomotor activity and induces lipid-metabolism disorders by impairing fatty acid oxidation in zebrafish.

Aims: Fluorene-9-bisphenol (BHPF), as a substitute for bisphenol A, is used in many industries in daily life. Many studies have clarified its effects as an endocrine disruptor on organisms, but its effect on lipid metabolism of zebrafish larvae is not clear. Patients with non-alcoholic fatty liver disease (NAFLD) are more susceptible to external pollutants.

Low concentrations of the antidepressant venlafaxine affect courtship behaviour and alter serotonin and dopamine systems in zebrafish (Danio rerio).

Venlafaxine, a serotonin-noradrenaline reuptake inhibitor, is a widely used antidepressant drug routinely detected in aquatic environments. However, its potential impact on courtship behaviour in zebrafish is unknown. We tested the hypothesis that venlafaxine disrupts brain monoamine levels and molecular responses essential for courtship behaviour in zebrafish.

Exogenous melatonin protects preimplantation embryo development from decabromodiphenyl ethane-induced circadian rhythm disorder and endogenous melatonin reduction.

Decabromodiphenyl ethane (DBDPE) is a novel flame retardant that is widely used in plastics, electronic products, building materials and textiles. Our previous studies have revealed the oocyte toxicity of DBDPE, but the effect of DBDPE on preimplantation embryo development has not been reported. Here, we investigated whether and how DBDPE exposure affects preimplantation embryo development.

Effect of 17β-trenbolone exposure during adolescence on the circadian rhythm in male mice.

The suprachiasmatic nucleus (SCN) is the main control area of the clock rhythm in the mammalian brain. It drives daily behaviours and rhythms by synchronizing or suppressing the oscillations of clock genes in peripheral tissue. It is an important brain tissue structure that affects rhythm stability.

Environmental exposure to 17β-trenbolone during adolescence inhibits social interaction in male mice.

Puberty is a critical period for growth and development. This period is sensitive to external stimuli, which ultimately affects the development of nerves and the formation of social behaviour. 17β-Trenbolone (17β-TBOH) is an endocrine disrupting chemicals (EDCs), which had been widely reported in aquatic vertebrates.

Indoor air quality investigation of a badminton hall in humid season through objective and subjective approaches.

This study investigated the indoor air quality (IAQ) during humid season in an old badminton hall, to explore the IAQ characteristics of natural ventilated sports buildings for public use. The indoor air parameters (temperature, relative humidity and air velocity) and indoor air pollutants (CO, TVOC, PM and PM) were measured. A subjective approach was carried out through questionnaire survey.

Exposure to Melamine cyanuric acid in adolescent mice caused emotional disorder and behavioral disorder.

Melamine cyanuric acid (MCA) is a flame retardant linked by hydrogen bonds between melamine and cyanuric acid. MCA is used in an excellent series of phosphorus and nitrogen flame retardants. MCA can harm the kidney, liver, testis, and spleen cells.

Melatonin alleviates the deterioration of oocytes and hormonal disorders from mice subjected to glyphosate.

Glyphosate (Gly) is the herbicide widely used in agricultural fields and landscaping. Mammalian exposure to glyphosate could cause neurotoxicity, blood, liver, kidney, endocrine, reproductive, genetic and other toxic effects. Melatonin (MT) is a neuroendocrine hormone secreted mainly by the pineal gland.

Polydatin alleviates parkinsonism in MPTP-model mice by enhancing glycolysis in dopaminergic neurons.

Parkinson's disease (PD) is a common neurodegenerative disease. Damage to energy metabolism and reduced adenosine triphosphate (ATP) levels in dopaminergic neurons are common features of PD. Previous studies suggested that the occurrence of PD often affects glucose metabolism and ATP production in the brain, and increased glycolysis or ATP production protects dopaminergic neuronal degeneration in the brain of PD patients.

Anti-neuroinflammatory effects of dimethylaminomylide (DMAMCL, i.e., ACT001) are associated with attenuating the NLRP3 inflammasome in MPTP-induced Parkinson disease in mice.

Parthenolide (PTL) is a natural compound with anti-inflammatory and antioxidant properties and is an active ingredient extracted from the medicinal plant Tanacetum parthenium. ACT001 is derived from parthenolide and is a fumarate form of dimethylaminomylide (DMAMCL). Its effect is equivalent to that of PTL, but it is more stable in plasma and has lower acquisition costs.

Effects of 17β-trenbolone exposure on sex hormone synthesis and social behaviours in adolescent mice.

17β-Trenbolone (17β-TBOH) is an endocrine disruptor that has been widely reported in aquatic organisms. However, little is known about the effect of 17β-TBOH on mammals, particularly on the development of adolescents. Through a series of behavioural experiments, exposure to at 80 μg kg  d and 800 μg kg  d 17β-TBOH during puberty (from PND 28 to 56, male mice) increased anxiety-like behaviours.

Combined treatment of melatonin and sodium tanshinone IIA sulfonate reduced the neurological and cardiovascular toxicity induced by deltamethrin in zebrafish.

The pyrethroid insecticide deltamethrin has been reported to have an effect on vertebrate development and cardiovascular disease. Sodium tanshinone IIA sulfonate (STS) is considered to have cardioprotective effects and melatonin is known to regulate sleep-waking cycles. In this experiment, we used transgenic zebrafish Tg (kdrl:mCherry) and Tg (myl7:GFP) to investigate whether STS and melatonin could reverse the cardiovascular toxicity and neurotoxicity induced by deltamethrin.

Heat Shock Protein Inspired Nanochaperones Restore Amyloid-β Homeostasis for Preventative Therapy of Alzheimer's Disease.

Amyloid beta (Aβ) aggregation is generally believed as the crucial and primary cause of Alzheimer's disease (AD). However, current Aβ-targeted therapeutic strategies show limited disease-modifying efficacy due to the irreversible damages in the late stage of AD, thus the treatment should be given before the formation of deposition and target primary Aβ species rather than advanced plaques. Herein, inspired by heat shock protein, a self-assembly nanochaperone based on mixed-shell polymeric micelle (MSPM) is devised to act as a novel strategy for AD prevention.

The parthenolide derivative ACT001 synergizes with low doses of L-DOPA to improve MPTP-induced Parkinson's disease in mice.

L-3,4-dihydroxyphenylalanine (L-DOPA) is currently the main drug used to treat Parkinson's disease (PD). However, long-term use of l-DOPA causes substantial side effects, and we hope to find a biological active ingredient that synergizes with a low-dose of l-DOPA to achieve the same therapeutic effect as that of a high-dose of l-DOPA. The natural product parthenolide (PTL) is the active ingredient in the medicinal plant feverfew (Tanacetum parthenium) and has antioxidant and anti-inflammatory properties.
