Proteasome structures affected by ionizing radiation.
Pervan M, Iwamoto KS, McBride WH. Pervan M, et al. Mol Cancer Res. 2005 Jul;3(7):381-90. doi: 10.1158/1541-7786.MCR-05-0032. Mol Cancer Res. 2005. PMID: 16046549
Regardless of whether they were irradiated before or after extraction and purification from human prostate cancer PC3 cells, 26S proteasomes remained intact but showed a rapid 30% to 50% dose-independent decrease in their three major enzymatic activities following exposure to 1 t …

High-intensity interval running impairs subsequent upper limb strength performance.
Andrade LS, David GB, Krüger VL, Wilhelm EN, Alberton CL. Andrade LS, et al. J Sports Med Phys Fitness. 2021 Jun;61(6):803-809. doi: 10.23736/S0022-4707.20.11458-0. J Sports Med Phys Fitness. 2021. PMID: 34110119
In the interval protocol, eight sprints of 40s at 100% of the velocity of maximal oxygen uptake, with 20s of passive interval between them were performed, whereas in the continuous protocol 30-min of treadmill running at 90% of the heart rate corresponding to second ventil …

METHODS: A 3D-printed root canal model with 2 parallel root canals (60-curvature, radius 5 mm, dimension 25/.06) with a total length of 20 mm connected via isthmuses (2.5 0.4 0.2 mm) at 5 mm and 8 mm from the apical endpoint and with lateral canals (diameter 0.2 mm) in all …

Hardness and fracture toughness of resin-composite materials with and without fibers.
Alshabib A, Silikas N, Watts DC. Alshabib A, et al. Dent Mater. 2019 Aug;35(8):1194-1203. doi: 10.1016/j.dental.2019.05.017. Epub 2019 Jun 6. Dent Mater. 2019. PMID: 31176452
For hardness measurement, materials were cured in 2mm thick molds for 20s by a LED source of average irradiance 1.2W/cm(2). Specimens (n=6/group) were stored dry for 1h and then in either water or 75% ethanol/water for 1h, 1 day and 30 days at 371C. ...RESULTS: VHN decreas …

Contact lens wear and care in Spain during the COVID-19 pandemic.
Vianya-Estopa M, Garcia-Porta N, Piñero DP, Simo Mannion L, Beukes EW, Wolffsohn JS, Allen PM. Vianya-Estopa M, et al. Cont Lens Anterior Eye. 2021 Oct;44(5):101381. doi: 10.1016/j.clae.2020.11.001. Epub 2020 Nov 11. Cont Lens Anterior Eye. 2021. PMID: 33246914 Free PMC article.
Respondents were found to be compliant with handwashing prior to inserting and removing contact lenses (in both cases 97% doing this 'most times' or 'every time'). However, only 44 % complied with the '20 s rule' and 48 % used a shared towel to dry their hands. A higher pr …

20(S)-hydroxycholesterol inhibits PPARgamma expression and adipogenic differentiation of bone marrow stromal cells through a hedgehog-dependent mechanism.
Kim WK, Meliton V, Amantea CM, Hahn TJ, Parhami F. Kim WK, et al. J Bone Miner Res. 2007 Nov;22(11):1711-9. doi: 10.1359/jbmr.070710. J Bone Miner Res. 2007. PMID: 17638575 Free article.
MATERIALS AND METHODS: The M2-10B4 (M2) murine pluripotent bone MSC line was used to assess the inhibitory effects of 20(S)-hydroxycholesterol (20S) and sonic hedgehog (Shh) on peroxisome proliferator-activated receptor gamma (PPARgamma) and adipogenic differentiati …

Pre-heating time and exposure duration: Effects on post-irradiation properties of a thermo-viscous resin-composite.
Yang J, Silikas N, Watts DC. Yang J, et al. Dent Mater. 2020 Jun;36(6):787-793. doi: 10.1016/j.dental.2020.03.025. Epub 2020 May 5. Dent Mater. 2020. PMID: 32386715
Two-way ANOVA showed that there was no significant interaction between pre-heating time and exposure duration (p>0.05). SIGNIFICANCE: Increasing irradiation time from 20 to 40s did not affect DC, RP(max) or PS, but increased VHN(top). Composite pre-heating had no advers …

DNA-damaging steroidal alkaloids from Eclipta alba from the suriname rainforest1.
Abdel-Kader MS, Bahler BD, Malone S, Werkhoven MC, van Troon F, David, Wisse JH, Bursuker I, Neddermann KM, Mamber SW, Kingston DG. Abdel-Kader MS, et al. J Nat Prod. 1998 Oct;61(10):1202-8. doi: 10.1021/np970561c. J Nat Prod. 1998. PMID: 9784152
Bioassay-guided fractionation of the MeOH extract of Eclipta alba using three yeast strains (1138, 1140, and 1353) resulted in the isolation of eight bioactive steroidal alkaloids (1-8), six of which are reported for the first time from nature. The major alkaloid was identified a …

White women experience their lowest rate of low birth weight (LBW) in their late 20s; the nadir LBW for African-American women is under 20 years with rates rising monotonically thereafter, hypothesized as due to "weathering" or deteriorating health with cumulative d …
