Pregnane X receptor (PXR) as a ligand dependent transcription factor, is capable of regulating gene expression of cytochromes P450 and transporters involved in xenobiotic/drug metabolism and elimination. Due to the species differences in the regulatory specificity of PXR, gene regulation should not be extrapolated from mammal to fish without research data.The aim of present study was to investigate the effect of 27 natural products on PXR, CYP3A30 and MDR1 genes in channel catfish (Ietalurus punetaus) kidney cells (CC-K). The results showed that bisdemethoxycurcumin, glycyrrhetnic acid, rotenone, artemisinin, dihydroartemisinin, ligustilide and matrine strongly induced the mRNA levels of PXR. Additionally, the up-regulation of CYP3A30 gene ran parallel with PXR gene after the treatment of demethoxycurcumin, glycyrrhetnic acid, artemisinin, matrine, baicalein, schisantherin A, ligustilide, and dihydroartemisinin. Moreover, we found that natural products schisandrin A, schisandrin B, schisandrol A, and schisandrol B significantly up-regulated the mRNA level of MDR1 gene.Our work with a view to provide experimental data support for further research, which will make for the rational application of natural products in channel catfish, such as to avoid adverse herb-drug interactions or accelerating the residue elimination of chemical medicine.Objective The study evaluated a smartphone-aided program to support independent access to leisure events and performance of daily activities in seven participants with moderate intellectual disability, four of whom also had severe hearing loss.Method The program relied on the use of a Samsung Galaxy J4 Plus smartphone with Android 9.0 operating system. The smartphone's functioning was automated via the MacroDroid application. The program was to allow the participants to alternate access to leisure events (delivered via the smartphone) with performance of vocational activities (guided through smartphone-delivered pictorial or pictorial and verbal instructions) over sessions of about 30 min.Results During the baseline, the participants failed to access leisure events and perform scheduled activities independently. When the program was used, however, all participants succeeded in both accessing leisure events and performing activities independently.Conclusions The smartphone-aided program can be a useful tool for people like the participants of this study.Chemotherapy-induced peripheral neuropathy (CIPN) is a chronic symptom associated with chemotherapy treatment. Symptoms and severity vary based on chemotherapeutic agent used and dose. At present, effective options for the prevention and treatment of CIPN are inadequate and clinical guidance is limited. Unknown mechanism of action, lack of efficacy in many traditional neuropathic pain medications, and inconsistent evidence in regard to drug therapy have further complicated evaluation of therapeutic options. Twenty-five studies were identified and evaluated for CIPN prevention and treatment potential. Findings for CIPN pharmacological prevention were inconclusive as literature was largely conflicting. Exercise may be an effective non-pharmacological CIPN prevention method with limited adverse effects, however additional supporting data is still required. For treatment of CIPN, pharmacological agents duloxetine and topical combination product containing baclofen, amitriptyline, and ketamine have data supporting use. Early stage trials have shown initial promise for non-pharmacological therapies Scrambler Therapy and Photobiomodulation. selleck inhibitor Significant research is required as CIPN symptoms can lead to decreased quality of life, chemotherapy dose reduction, and discontinuation of drug therapy.The objective of the present study was to evaluate the sexual behavior of male rats kept under constant laboratory conditions for one entire year. A total of 213 sexually-inexperienced, male Wistar rats were maintained in controlled environmental conditions from birth. Depending the month in which they reached the age 3-month-old, the male rats were divided into 12 groups, one for each month of the year, and their sexual behavior was evaluated. Records of their sexual behavior were made from 0900 to 1100 hrs am. The following parameters were recorded mount (latency and number), intromission (latency and number), ejaculation latency, and intromission rate. During the months of March, June, July and September, the rats showed lower mount and intromission latencies than in January, February, April, May and October-to-December. Similarly, in March, June, July and August they had higher copulatory efficiency than in January, February, April and December. Results suggest that male rats exposed to controlled environmental conditions could have endogenous mechanisms that regulate sexual behavior but are independent of seasonal environmental signals. The annual variability in the sexual behavior of male rats maintained under constant laboratory conditions should be considered when planning research and experiments.Chronic sciatic pain is difficult to treat. Patients often suffer from considerable pain and are severely hampered in their everyday activities. Most pharmacologic analgesic treatments have disappointing effects, and often are limited due to adverse events. New treatments are therefore needed. Surprisingly we found fast pain reduction after applying topical phenytoin cream at the painful dermatome in a 55-year-old patient suffering from sciatic pain due to pathology of a disc. This patient was treatment resistant for 13 years. Prescribing topical analgesic cream seemed to us at first sight quite counter-intuitive. The clear response in a treatment-resistant patient however provoked us to look deeper in the pathophysiology of sciatic nerve impingement. Recently it has been documented that proximal nerve lesions are followed by small fiber pathology in the skin. This might be a responsible peripheral wind-up generator for the chronification of pain in sciatic nerve compression. Topical application of the broad-acting voltage-gated sodium channel blocker phenytoin could reduce neuropathic pain in our case completely, supporting a peripheral mechanism of action for phenytoin cream in sciatic pain.
