The differences of basic attributes, health promotion behaviors, and quality of life between elderly males and females in Taiwan were compared. Several scales were used to examine the gender differences and the factors associated with quality of life. Regression analysis revealed that gender, education level, depression level, and healthy diet were key factors influencing the overall quality of life. The education level of females was lower, and their depression level was higher; however, females had healthier diets. With regards to their satisfaction in the quality of life, elderly males scored higher than females in both the physical and psychological domains. [ABSTRACT FROM AUTHOR]

Various acidic anhydrides including cantharidin were converted into corresponding aminobenzylcantharidinimide 3a and analogous imides 3b∼k (at the ortho, meta, and para positions) with 35%∼87% yields by reacting with aminobenzylamines and triethylamine. The two methyl side chains of cantharidinimides 3ao, 3am, and 3ap, and related imides had more than two chiral centers; the lone pair of electrons of nitrogen displayed a different chemical shift and coupling constant in H-NMR spectra when the amino group of benzylamine was in the ortho position. These cantharidinimides had parent aniline, pyridine, and naphthalene plane structures, and the primary amine nucleophilicity and basicity might reflect the inductive electron's negative effect on chemical shifts. We prepared cantharidinimides by heating the reactants cantharidin 1a, aliphatic and aromatic acid anhydrides, primary benzylic amines, and aniline derivatives to ca. 200 °C with 3 mL of dry toluene, and 1∼2 mL of triethylamine in high-pressure sealed tubes (Buchi glasuster 0032) to produce cantharidinimides and their analogues in good yields. The para-aminobenzylic imides showed greater inhibition of nitric oxide (NO) synthesis by NO synthase (NOS) than did ortho- and meta-aminobenzylic imides. Compound 3fp, para-aminobenzylic norbonane-imide, had the most potent effect on inducible NOS among the tested compounds and showed 35% inhibition. [ABSTRACT FROM AUTHOR]

A series of thiochromeno[2,3- c ]quinolin-12-one derivatives with various substitutions were synthesized and evaluated as topoisomerase (Topo) inhibitors. Six (8 , 10 , 12 , 14 , 19 , and 26) of 23 compounds showed strong inhibitory activities against Topo-mediated DNA relaxation and proliferation of five human cell lines including breast (MDA-MB-231, MDA-MB-468 and MCF7), colorectal (HCT116) and non-small cell lung (H1299) cancers. Among these, compounds 14 and 26 exhibited full inhibitory activities against Topo I at 3 μM and Topo IIα at 1 μM. Cancer cells treated with 26 accumulated DNA damage and were arrested at the G 2 /M phase. With time, cells proceeded to apoptosis, as revealed by increased amounts of cells with fragmented DNA and cleavage of caspase-8 and -9. In contrast, normal breast epithelial cells showed low sensitivity to 26. Taken together, our study identifies 26 as a potent Topo dual-inhibitor with low toxicity to normal cells, and elucidates that the terminal amino group of N -2-aminoethylamino or N -3-aminopropylamino at the 6th position and 8,10-di-halogen substituents on thiochromeno[2,3- c ]quinolin-12-one are critical for the Topo-inhibiting and cancer-killing activities. Image 1 • Six compounds identified as dual Topo inhibitors. • 26 exhibits the highest toxicity in five cancer cell lines but is less toxic in normal breast epithelial cells. • 26 traps Topo I and IIα on chromatin and suppresses their activities. • 26 triggers DNA damage, cell-cycle arrest at the G 2 /M phase, followed by apoptosis.

Background: The prognosis of patients with liver cirrhosis often involves multiple complications and repeated admissions, which may significantly burden and reduce the quality of life of the primary caregivers of these patients., Purpose: The purpose of this correlational study was to explore the relationship between the burden of caregivers of liver cirrhosis patients and their quality of life., Methods: A structured questionnaire, which included the Primary Caregiver Burden Scale, Coping Behaviors Scale, the WHOQOL-BREF, and a caregiver demographic datasheet, was used to collect data. Descriptive and inferential statistics (independent t-test, one-way ANOVA, Pearson's product-moment correlation, and stepwise regression analysis) were used to analyze data., Results: A total of 113 participants were recruited from a medical center in northern Taiwan. The results revealed: (1) The highest average scores for caregiver burden were in the financial domain, while the lowest average scores were in the physical domain. The highest average scores for quality of life were observed in the environment domain, while the lowest average scores were in the physical health domain. (2) Most of the caregivers adopted a problem-solving oriented strategy to care for their patient. (3) Overall care burden correlated negatively with overall quality of life (r = -.223, p < .05). The caregivers' "self-assessed health", "financial load", and "daily care hours" were significant factors affecting overall quality of life (F = 52.78, p < .05), accounting for 58% of the total variance in the results., Conclusions: The results of this study may help nurses better understand and work to reduce the burden of caregivers in order to enhance their quality of life. Nurses should assess caregiver burden, especially in cases where caregivers themselves are in a poor financial situation or have poor self-assessed health, in order to provide necessary support and assistance.

Background: Obstructive sleep apnea (OSA) is a potentially lethal respiratory sleep disorder. However, few studies have studied OSA women., Purpose: The purpose of the current study was to explore the life experiences of women with OSA., Methods: A qualitative study using the grounded theory method was used to establish a descriptive theory., Results: The results were expressed in terms of three stages with related categories. Stage 1: No interest days due to poor sleep, including "uncontrollable sleep", "perceived health deteriorates", and "poor female image harmed by snoring"; Stage 2: Indecision and disappointments during treatment seeking, including "doctor shopping", "being urged by others to seek medical help", and "being shocked by the severity of disease"; and Stage 3: Accepting a new lifestyle with a continuous positive pressure respirator, including "adaptation of the new sleep", "adequate sleep", and "secret worry of being an OSA woman"., Conclusions: Based on the findings of the present study, medical knowledge and treatments related to OSA should be widely promoted with appropriate professional education and counseling services in order to enhance the awareness of patients and to facilitate their acceptance of the healing process using a continuous positive airway pressure respirator.
