This project was initiated to better understand medical trainee perspectives on training and providing healthcare services to prison populations at one AMC specializing in the care of incarcerated patients: The University of Texas Medical Branch at Galveston (UTMB). We set out to characterize the attitudes and perceptions of medical trainees from the start of their training until the final year of Internal Medicine residency. Our goal was to analyze medical trainee perspectives on caring for incarcerated patients and to determine what specialized education and training is needed, if any, for the provision of ethical and appropriate healthcare to incarcerated patients. Results We found that medical trainees grapple with being beneficiaries of a state and institutional power structure that exploits the neglected health of incarcerated patients for the benefit of medical education and research. The benefits include the training opportunities afforded by the advanced pathologies suffered by persons who are incarcerated, an institutional culture that generally allowed students more freedom to practice their skills on incarcerated patients as compared to free-world patients, and an easy compliance of incarcerated patients likely conditioned by their neglect. Most trainees failed to recognize the extreme power differential between provider and patient that facilitates such freedom. Conclusions Using a critical prison studies/Foucauldian theoretical framework, we identified how the provision/withholding of healthcare to and from persons who are incarcerated plays a major role in disciplining incarcerated bodies into becoming compliant medical patients and research subjects, complacent with and even grateful for delayed care, delivered sometimes below the standard best practices. Specialized vulnerable-population training is sorely needed for both medical trainees and attending physicians in order to not further contribute to this exploitation of incarcerated patients.The University of Kansas (KU) One University Open Access Author Fun

    <div><p>The stem bark extracts of <i>Knema laurina</i> inhibited the hydrogen peroxide (H<sub>2</sub>O<sub>2</sub>)- and aggregated amyloid β-peptide 1–42 length (Aβ<sub>1–42</sub>)-induced cell death in differentiated SH-SY5Y cells. Exposure of 250 μM H<sub>2</sub>O<sub>2</sub> or 20 μM Aβ<sub>1–42</sub> to the cells for 24 h reduced 50% of cell viability. Pretreatment of cells with ethyl acetate extract (EAE) or <i>n</i>-butanol extract (BE) at 300 μg/mL and then exposure to H<sub>2</sub>O<sub>2</sub> protected the cells against the neurotoxic effects of H<sub>2</sub>O<sub>2</sub>. Besides, methanolic extract (ME) at 1 and 10 μg/mL exerted neuroprotective effect on Aβ<sub>1–42</sub>-induced toxicity to the cells. These results showed that EAE, BE and ME exhibited neuroprotective activities against H<sub>2</sub>O<sub>2</sub>- and Aβ<sub>1–42</sub>-induced cell death. Flavonoids (<b>3</b>–<b>6</b>) and β-sitosterol glucoside (<b>8</b>) were isolated from the EAE. Compound <b>1</b> was isolated from hexane extract, and compounds <b>2</b> and <b>7</b> were isolated from dichloromethane extract. All these observations provide the possible evidence for contribution in the neuroprotective effects.</p></div

    Background Curcumin is one of the leading compound extracted from the dry powder of Curcuma longa (Zingiberaceae family), which possess several pharmacological properties. However, in vivo administration exhibited limited applications in cancer therapies. Results Twenty-four curcumin derivatives have synthesized, which comprises cyclohexanone 1–10, acetone 11–17 and cyclopentanone 18–24 series. All the curcuminoids were synthesized by the acid or base catalyzed Claisen Schmidt condenstion reactions, in which β-diketone moiety of curcumin was modified with mono-ketone. These curcuminoids 1–24 were screened against HeLa, K562, MCF-7 (an estrogen-dependent) and MDA-MB-231 (an estrogen-independent) cancer cell lines. Among them, acetone series 11–17 were found to be more selective and potential cytotoxic agents. The compound 14 was exhibited (IC50 = 3.02 ± 1.20 and 1.52 ± 0.60 µg/mL) against MCF-7 and MDA-MB-231 breast cancer cell lines. Among the cyclohexanone series, the compound 4 exhibited (IC50 = 11.04 ± 2.80, 6.50 ± 01.80, 8.70 ± 3.10 and 2.30 ± 1.60 µg/mL) potential cytotoxicity against four proposed cancer cell lines, respectively. All the curcucminoids were characterized with the detailed 1H NMR, IR, UV–Vis, and mass spectroscopic techniques. The structure of compound 4 was confirmed by using the single X-ray crystallography. Additionally, we are going to report the first time spectral data of (2E,6E)-2,6-bis(2-methoxybenzylidene)cyclohexanone (1). Structure–activity relationships revealed that the mono-carbonyl with 2,5-dimethoxy substituted curcuminoids could be an essential for the future drugs against cancer diseases. Conclusions Curcuminoids with diferuloyl(4-hydroxy-3-methoxycinnamoyl) moiety with mono carbonyl exhibiting potential cytotoxic properties. The compound 14 was exhibited (IC50 = 3.02 ± 1.20 and 1.52 ± 0.60 µg/mL) against MCF-7 and MDA-MB-231 breast cancer cell lines
