The study determined the content of biogenic amines in dry-cured pork loins inoculated with Lactobacillus casei ŁOCK 0900 probiotic strain, in 4, 8 and 16 month-old samples. Cadaverine, putrescine and tryptamine levels showed a time-dependent increase during ageing. Histamine and spermidine were not detected. Spermine which was present at very low concentrations, tended to decrease. Cadaverine and tryptamine were the main biogenic amines at the end of the ageing period with average values of 39.6 mg/kg and 49.2 mg/kg respectively. The results were within the values reported for other dry-cured meat products and below the suggested toxic levels. The pH of samples increased significantly (p<0.05) with ageing time. The a(w) values decreased significantly (p<0.05) during ageing, with a mean value of 0.953±0.007 for samples aged for 4 months, and 0.852±0.007 for samples aged for 16-months.

The aim of this study was to evaluate the effects of two styles of classical music, based on different tempos (BPM), on the physiological and blood parameters of horses during social isolation and restriction of movements. First experiment was carried out using nine horses of no defined breed, distributed in Control, Slow-tempo music and Moderate-tempo music .For social isolation and restriction of movement, the animals were housed daily in individual stalls for two hours and exposed to the stimuli for 60 min, and eye temperature, heart rate, and respiratory rate were assessed.

Growth regulators can improve the quality and production of fruit trees. This research was conducted over two successive years to evaluate the effect of preharvest sprays of growth regulators on the physicochemical properties of date palm fruit (Phoenix dactylifera cv. 'Shahabi') during khalal and tamar stages in a palm research station at Bushehr province.

Signaling interplay between the histamine 1 receptor (H1R) and transient receptor potential cation channel subfamily V member 1 (TRPV1) in mediating histaminergic itch has been well-established in mammalian models, but whether this is conserved in humans remains to be confirmed due to the difficulties in obtaining human sensory neurons (SNs) for experimentation. Additionally, previously reported species-specific differences in TRPV1 function indicate that use of human SNs is vital for drug candidate screening to have a higher chance of identifying clinically effective TRPV1 antagonists. In this study, we built a histamine-dependent itch model using peripheral SNs derived from human induced pluripotent stem cells (hiPSC-SNs), which provides an accessible source of human SNs for pre-clinical drug screening.

According to the Food and Agriculture Organization of the United Nations (FAO) more than 14% of the world's food production is lost every year before reaching retail, and another 17% is lost during the retail stage. The use of the expiration date as the main estimator of the life-end of food products creates unjustified food waste. Sensors capable of quantifying the effective food freshness and quality could substantially reduce food waste and enable more effective management of the food chain.

Tumor heterogeneity, immune-suppressive microenvironment and the precise killing of tumor cells by drugs are important factors affecting tumor treatment. In this study, we developed environment-responsive drug delivery system (FM@IQ/PST&ZIF-8/DOX) based on ZIF-8 for tumor photothermal/immunotherapy/chemotherapy synergistic therapy. The prepared FM@IQ/PST&ZIF-8/DOX nanoplatfrom not only has highly drug loading capacity for chemotherapeutic drug-doxorubicin, but also erythrocyte membrance modified on their surface can endow their immunity-escaping property and prolong their blood circulation time.
