Additionally, CYP3A4 was observed to function as an enzyme mainly involved in the biotransformation of NOT. Taken together, these findings indicate that NOT served as a mechanism-based inactivator of CYP2D6, meanwhile, those observed effects may induce the latent drug-drug interactions. The metabolic activation of NOT may be the key to trigger the inactivation of the enzyme. Cytochrome P450 (P450) 2E1 is the major P450 enzyme involved in ethanol metabolism. That role is shared with two other enzymes that oxidize ethanol, alcohol dehydrogenase and catalase. P450 2E1 is also involved in the bioactivation of a number of low molecular weight cancer suspects, as validated in vivo in mouse models where cancers could be attenuated by deletion of Cyp2e1. P450 2E1 does not have a role in global production of reactive oxygen species but localized roles are possible, e.g. in mitochondria. The structures, conformations, and catalytic mechanisms of P450 2E1 have some unusual features among P450s. The concentration of hepatic P450 varies ≥10-fold among humans, possibly in part due to single nucleotide variants. The level of P450 2E1 may have relevance in the rates of oxidation of drugs, particularly acetaminophen and anesthetics. OBJECTIVES Data on the safety and efficacy of cabazitaxel in patients aged ≥80 years with castration-resistant prostate cancer (CRPC) are limited. We report the safety (adverse drug reactions [ADRs]) and efficacy (overall survival [OS], time to treatment failure [TTF], and prostate-specific antigen [PSA] response rates) in patients aged less then 80 or ≥80 years treated with cabazitaxel for CRPC in clinical practice. MATERIALS AND METHODS We performed post-hoc subgroup analyses of a Japanese post-marketing surveillance study involving 662 patients with CRPC treated with cabazitaxel between September 2014 and June 2016. RESULTS In patients aged less then 80 (n = 610) and ≥80 years (n = 49), median PSA at baseline was 168.7 and 109.0 ng/mL, and 86.7% and 83.7% of patients were previously treated with enzalutamide and/or abiraterone. ADRs (all grade) occurred in 77.2% and 79.6% of patients aged less then 80 and ≥80 years, with grade three/worse ADRs in 61.8% and 63.3% of patients. Hematologic toxicities were the most common grade three/worse ADRs, including neutropenia, febrile neutropenia, and anemia in both subgroups. No specific ADRs were observed in patients aged ≥80 years. The PSA response and median OS and TTF were 28.3%, 292 days, and 116 days in patients aged ≥80 years, and 29.7%, 319 days, and 125 days in patients aged less then 80 years. CONCLUSION Cabazitaxel could be a treatment option for CRPC in patients aged ≥80 years based on its safety and efficacy profiles. This is the first report to investigate the safety and efficacy of cabazitaxel in patients aged ≥80 years with CRPC. Ethnopharmacological relevance Oral squamous cell carcinoma (OSCC) is one of the most common malignant tumors, seriously compromising patients' quality of life. Previous studies showed that Zengshengping (ZSP), a popular traditional Chinese medicine, has certain inhibiting effects on both oral precancerous lesions and OSCC. However, few reports underlined ZSP side effects such as liver toxicity, which limit its long-term application. Aim of the study was to evaluate the chemopreventive effect of a modified ZSPs formula on oral cancer in a hamster model. Its effect on hamster liver was also assessed. Materials and Methods The original medicine (ZSP-1) and other two formulas slightly different and called ZSP-2 and ZSP-3 were prepared ahead of time. DMBA (0.5%) was topically applied for 6 weeks to induce a premalignant lesion on hamsters' cheek pouch, then ZSP-1/2/3 were intragastrically administered for 8 weeks. Hamster treated with DMBA + each of the ZSPs represented the ZSP-1/2/3 groups, while those without Zd with an intragastric administration of ddH2O. After 4 weeks of withdrawal, the hamsters of the ZSP-3 group did not recover from the increase in ALP. Histopathology showed the presence of inflammatory lesions in each group after 12 weeks, especially in the ZSP-1/3 groups, and the number of apoptotic cells in the ZSP-3 group was higher than that in the other groups, without any recovery after withdrawal of the drug. find more At 12 weeks, the MDA in the ZSP-1 group was higher than that in the control group and the ZSP-2 group, but the difference disappeared after drug withdrawal because the MDA in the ZSP-1/3 groups decreased. Conclusions ZSP-2 possessed a chemopreventive effect against oral cancer by inhibiting inflammation, proliferation of tumor cells, generation of microvessels and by promoting tumor cell apoptosis. In addition, hepatotoxicity of ZSP-2, which might be related to oxidative stress injury, was reduced to some extent. PURPOSE To describe the surgical management, dose-response, and postoperative outcomes of strabismus surgery in patients with thyroid eye disease. METHODS The medical records of patients operated on between 2014 and 2018 were reviewed retrospectively. Patient characteristics and surgical data were collected. Motor success was defined as vertical deviation of ≤5Δ and horizontal deviation of ≤10Δ; sensory success, as no diplopia in primary gaze. RESULTS A total of 76 patients (mean age, 62.2 ±12.9 years; 50 females) underwent 87 surgeries, most commonly unilateral inferior rectus recession (unilateral IR, 48%) and bilateral medial rectus recession (bilateral MR, 23%). Motor success was achieved in 69% and sensory success in 58%. For unilateral IR surgery, the dose-responses were 3.25Δ/mm (SE = 0.616; β = 0.650; P less then 0.001) at distance and 2.48Δ/mm (SE = 0.752; β = 0.472; P = 0.002) at near; for bilateral MR surgery, 3.93Δ/mm (SE = 0.997; β = 0.680; P = 0.001) at distance and 5.05Δ/mm (SE = 1.374; β = 0.655; P = 0.002) at near. Median (Q1, Q3) postoperative drift was toward overcorrection for both procedures (unilateral IR, -2Δ [-8, 0] at distance and -2Δ [-7, 0] at near; bilateral MR, -2Δ [-8, 2] at distance and -2Δ [-10, 0] at near). Sex, age, duration of strabismus, prior orbital decompression, and concurrent vertical and horizontal procedures were not associated with dose-response or postoperative drift. CONCLUSIONS Concurrent vertical and horizontal surgery did not affect the motor success rate, dose-response, or postoperative drift. Although unilateral IR surgery had a larger dose-response at distance, bilateral MR surgery had a larger dose-response at near. Most procedures tended to have a postoperative drift toward overcorrection.
