Korean-speaking learners of Mandarin Chinese and naïve listeners labeled voiceless unaspirated stops preceded or followed by low or high extrinsic tonal context (e.g., maLO.pa vs. maHI.pa) either as lenis (associated with a low F0 at the vowel onset) or as fortis stops (with a high F0). Further, the target tone itself varied between level and rising (e.g., maLO.paLEV vs. maLO.paRIS). Both groups of listeners showed significant contrastive effects of extrinsic context. Specifically, more lenis responses were elicited in a high tone context than in a low one, and vice versa. This indicates that the onset F0 of a stop is perceived lower in a high tone context, which, in turn, provides positive evidence for lenis stops. This effect was more clearly pronounced for the level than for the contour tone target and also for the preceding than for the following context irrespective of linguistic experience. Despite qualitative similarities, learners showed larger effects for all F0 variables, indicating that the degree of context effects may be enhanced by one's phonetic knowledge, namely sensitivity to F0 cues along with the processing of consecutive tones acquired through learning a tone language.The current cancer research focuses on the design and synthesis of chemical compounds that can modulate cell apoptosis or programmed cell death. So we synthesized and characterized ciprofloxacin based copper(II) complexes and studied their anticancer activity against HCT 116 cancer cells by MTT assay. We further investigated the influence of compound-2 (better IC50 value than cisplatin) on cancer cells to know the exact mechanism of anticancer activity. The distinct morphological change of cells due to compound-2 was observed in bright field microscopy. The trypan blue assay clearly demonstrated inhibition of cell viability. The clonogenic ability inhibition assay showed a low percentage of the plating efficiency of HCT 116 cells. The mechanism of cell death, either apoptotic or necrotic was distinguished by annexin V-FITC/PI (propidium iodide) staining assay and LDH (lactate dehydrogenase) release assay. The positive annexinV/PI cells in presence of compound-2 and absence of LDH in the LDH release assay confirmed the cell apoptotic mechanism of cell death. We also checked in vitro antibacterial activity of compounds against Gram(-ve) and Gram(+ve) bacteria in terms of MIC (minimum inhibitory concentration) and the data were in good agreement with the standard drug data. SOD mimic activity of synthesized Cu(II) complexes was also studied in terms of IC50 value. The brine shrimp lethality bioassay was also performed to evaluate the cytotoxic properties of the Cu(II) complexes.Communicated by Ramaswamy H. Sarma.Background Premature ejaculation has a complex etiology, and its pathophysiology is still unclear, with penile hypersensitivity being the most accepted hypothesis. The aim was to investigate the efficacy and safety of a computed tomography-guided pudendal nerve block at the level of the sacrospinous ligament and the Alcock's canal in patients with premature ejaculation refractory to conventional pharmacological treatment.Methods This is a prospective pilot study involving five patients suffering from premature ejaculation refractory to standard treatment and clinical features of pudendal nerve entrapment. A CT-guided infiltration of ropivacaine and methylprednisone was done at the levels of sacrospinous ligament and Alcock's canal. Intra-vaginal ejaculatory latency time (IELT) was recorded several times for each patient before and after infiltration. International Index of Erectile Function (IIEF-5), Premature Ejaculation Diagnostic Tool (PEDT) and Sexual Quality of Life-Male version (SQoL-M) questionnaire were also evaluated before and after infiltration.Results Overall IELT differed significantly before and after treatment (21.94 vs 215.42 s; p = 0.039). IIEF-5, PEDT and SQoL-M also differed significantly before and after treatment. No complications for the CT-guided infiltration were recorded.Conclusion CT-guided pudendal nerve block at the sacrospinous ligament and the Alcock's canal was effective in improving premature ejaculation. Therefore, pudendal nerve entrapment may be a curable cause of sensory premature ejaculation.The experiences of Tourette syndrome (TS) caregivers with supportive communication are examined in this qualitative investigation. TS is a childhood-onset neurodevelopmental disorder marked by a combination of involuntary verbal and motor tics lasting for more than 1 year. Although individuals are impacted the most by TS, the stress for caring for a child with TS takes an emotional and physical toll on the caregiver. Eleven participants shared their experiences with receiving supportive communication by taking part in semi-structured interviews. Data analysis yielded three themes (a) TS caregivers describe their experiences as a struggle; (b) they seek out specific social support from friends and families; and (c) they frequently receive social support that increases instead of reducing stress.Background There are limited data to inform policy mandating primary percutaneous coronary intervention (PPCI) volume benchmarks for catheterization laboratories in low- and middle-income countries. Methods and Results This prospective state-wide registry included ST-segment-elevation myocardial infarction patients with symptoms of less then 12 hours, or with ongoing ischemia at 12 to 24 hours, reperfused with PPCI. From June 2013 to March 2016, we recruited 5560 consecutive patients. We categorized hospitals on the basis of annual PPCI volumes into low, medium, and high volume ( less then 100, 100-199, and ≥200 PPCIs per year, respectively). Kaplan-Meier curves and Cox regression models were used to examine the association between PPCI volume and 1-year mortality. Among 42 recruiting hospitals, there were 24 (57.2%) low-volume, 8 (19%) medium-volume, and 10 (23.8%) high-volume hospitals. NVP-BGT226 chemical structure The median (25th-75th percentile) TIMI (Thrombolysis in Myocardial Infarction) ST-segment-elevation myocardial infarction risk score was 3 (2-5).
