Objective: To identif y the maximum tolerated dose (MTD) of docetaxel combined with afixed dose of cisplatin (75 mg/m2) delivered as hyperthermic intraperitoneal chemotherapy(HIPEC) in patients with ovarian cancer. Methods: In this phase I trial, a time-to-event Bayesian optimal inter val design was used. Docetaxel was given at a starting dose of 60 mg/m2 and was increased in 5 mg/m2 incrementsuntil the MTD was determined or the maximum dose level of 75 mg/m2 was reached. The dose-limiting toxicity (DLT) rate was set at 25%, with a total sample size of 30 patients. HIPEC wasdelivered immediately following debulking surger y at a target temperature of 43°C for 90 minutes. Results: From August 2022 to November 2022, 30 patients were enrolled. Among thepatients who received a dose of docetaxel ≤65 mg/m2, no DLT was reported. DLTs wereobser ved in one patient who received 70 mg/m2 docetaxel (grade 3 anaemia) and in threepatients who received 75 mg/m2 docetaxel (one case of grade 3 anaemia, one case of grade3 hepatic impairment and one case of grade 4 thrombocytopenia). Patients treated withdocetaxel 75 mg/m2 in combination with cisplatin 75 mg/m2 had an estimated DLT rate of25%, which was the closest to the target DLT rate and was therefore chosen as the MTD. Conclusion: Docetaxel, in combination with a fixed dose of cisplatin (75 mg/m2), can be usedsafely at intraperitoneal doses of 75 mg/m2 in ovarian cancer patients who received HIPEC(43°C, 90 minutes) following debulking surger y.

In this paper, cognitive radio and simultaneous wireless information and power transfer (SWIPT) are effectively combined to design a spectrum-efficient and energy-efficient transmission paradigm. Specifically, a novel SWIPT-based primary-secondary cooperation model is proposed to increase the transmission rate of energy/spectrum constrained users. In the proposed model, a multi-antenna secondary user conducts simultaneous energy harvesting and information forwarding by means of power splitting (PS), and tries to maximize its own transmission rate under the premise of successfully assisting the data delivery of the primary user. After the problem formulation, joint power splitting and beamforming optimization algorithms for decode-and-forward and amplify-and-forward modes are presented, in which we obtain the optimal PS factor and beamforming vectors using a golden search method and dual methods. Simulation results show that the proposed SWIPTbased primary-secondary cooperation schemes can obtain a much higher level of performance than that of non-SWIPT cooperation and non-cooperation schemes.

Objective: Self-sampled human papillomavirus (HPV) testing is a potential option forcer vical cancer screening, but research is scarce in Cambodia. We evaluated the feasibility,accuracy, and acceptability of self-sampled HPV testing using careHPV. Methods: A cross-sectional study including women aged 20–49 years attending 2 nationalhospitals in the capital city was conducted. Women under went both self-sampling andclinician-sampling of specimens, and were then asked to complete an acceptabilityquestionnaire. The paired samples were analyzed for high-risk HPV by careHPV andgenotyped by polymerase chain reaction (PCR). Results: A total of 375 women were eligible for inclusion. Based on PCR, 78.9% were negativefor HPV in both self and clinician-samples, 9.9% had a complete HPV type match, and 6.1%had all HPV types in clinician-samples also detected in self-samples. In 5.1%, one or more HPVtypes identified in the clinician-samples were missed in self-samples. When using careHPV,the overall agreement between the 2 sampling methods was 95.7% (95% confidence inter val[CI]=95.8–95.6) with good concordance (κ=0.66, 95% CI=0.56–0.76). Nearly 90% of the womenpreferred clinician-sampling over self-sampling, citing greater comfort, ease, and speed. Conclusion: Self-sampled HPV testing using careHPV could be an option for cer vical cancerscreening in Cambodia; however, it requires periodic quality control of handling procedures. In addition, women’s health education regarding the accuracy of self-sampled HPV testingand the importance of follow-up in cases of positive results is needed.

By acid polyacrylamide gel electrophoresis (A-PAGE) analysis,it was indicated that the electrophoresis mobility of gliadins from Crithopsis delileana (Schult) Roshev (2n=2x=14,KK) had obvious difference with those from common wheat in α, γ and ω region. Using homologous primers, two γ-gliadin genes (gli-Kr1 and gli-Kr2) were isolated from C. delileana,which had been deposited in the GenBank under accession numbers EU283818 and EU283821, respectively. Two γ-gliadin genes of C. delileana had the similar primary structures to the corresponding gene sequences from other wheat related species. The differences were mainly resulted from substitutions,insertions and deletions involving single amino acid residues or motifs of γ-gliadins. The repetitive domains of gli-Kr1 and gli-Kr2 from C. delileana are shorter than most of other sequences. By the alignment of γ-gliadin genes from A, B, D, Am, Au, S, Sl, Ssh, Ss and Sb genomes of Triticum and Aegilops, R genome of Secale (γ-secalin), Ee genome of Lophopyrum and K genome of Crithopsis in Triticeae, phylogenetic analysis indicated that two γ-gliadin genes of C. delileana could be clustered together with a γ-gliadin genefrom Ssh genome of Aegilops by an interior paralleled branch. It was the first time that the γ-gliadin genes encoded by K genome of C. delileana were characterized. These could offer precious information for better understanding the qualities associated with gliadins, the response in coeliac disease and studying the evolutionary relationship of gliadins in Triticeae.

Using RT-PCR and rapid amplification of cDNA ends, two new full-length cDNAs of SAD (TaSAD1 and TaSAD2) were obtained from a hardiest winter wheat cultivar (Mironovskaya808). Sequence comparison analysis showed that the deduced amino acid sequences of TaSAD1 and TaSAD2 had high similarity to those of other reported SAD proteins. They were also different each other by some substitutions, insertions and/or deletions involving single amino acid residues or motifs. Based on evolution analysis, it was clear that all SAD genes from Poaceae were closer than those from other genus such as Arabidopsis,Glycine, Triadica, Brassica, Sesamum and Bassia. All SAD genes clustered into two major groups in Poaceae. Meanwhile,TaSAD1 and TaSAD2 were clustered into different groups. The tertiary structure prediction indicated that both TaSAD1 and TaSAD2 proteins were a compact globular protein and their model structures almost were the same.

Rapid industrial and agricultural development has dramatically increased the emission of selenium (Se) and mercury (Hg) into the environment. Combined soil pollution by Se and Hg poses a potential threat to crop production. However, no toxic effects of Hg–Se interactions on plants have been reported previously. In this study, we investigated the effects of Hg–Se interactions on biochemical and physiological indices in the roots of Brassica rapa (LvLing). Seedlings were treated hydroponically with solutions of mercury chloride (1 μM), sodium selenite (4 μM), or a combination of the two. Combined Hg+Se treatment significantly inhibited root growth, reduced root biomass, and enhanced reactive oxygen species (ROS) and malondialdehyde accumulation and led to a loss of plasma membrane integrity. The combined treatment increased glutathione peroxidase, glutathione S-transferase, and peroxidase activity, reduced superoxide dismutase activity, and had no effect on catalase activity. In addition, we detected increased glutathione concentrations in root tips and reduced ascorbic acid concentrations in the presence of Hg+Se relative to individual treatments with these elements. Thus, Hg–Se interactions enhanced oxidative injury, cell death, and phytotoxicity in B. rapa roots.
