The evolutionary origin of cardiac chambers.
Simões-Costa MS, Vasconcelos M, Sampaio AC, Cravo RM, Linhares VL, Hochgreb T, Yan CY, Davidson B, Xavier-Neto J. Simões-Costa MS, et al. Dev Biol. 2005 Jan 1;277(1):1-15. doi: 10.1016/j.ydbio.2004.09.026. Dev Biol. 2005. PMID: 15572135 Free article. Review.
Analyzing chordates, lower and higher vertebrates, we propose a paradigm picturing vertebrate hearts as advanced circulatory pumps formed by segments, chambered or not, devoted to inflow or outflow. We suggest that chambers arose not as single units, but as componen …

On the length used for CT ionization chambers to determine CTDI.
DeWerd LA, Khan AU, Jensen AR. DeWerd LA, et al. Phys Med Biol. 2022 Apr 7;67(8). doi: 10.1088/1361-6560/ac60b8. Phys Med Biol. 2022. PMID: 35325885
Objective.Computed tomography dose index (CTDI) calculations based on measurements made with CT ionization chambers require characterization of two chamber properties: radiation sensitivity and effective length. ...CTDI calculation results illustrate the potential 1 …

Remodeling nanodroplets into hierarchical mesoporous silica nanoreactors with multiple chambers.
Ma Y, Zhang H, Lin R, Ai Y, Lan K, Duan L, Chen W, Duan X, Ma B, Wang C, Li X, Zhao D. Ma Y, et al. Nat Commun. 2022 Oct 17;13(1):6136. doi: 10.1038/s41467-022-33856-y. Nat Commun. 2022. PMID: 36253472 Free PMC article.
Multi-chambered architectures have attracted much attention due to the ability to establish multifunctional partitions in different chambers, but manipulating the chamber numbers and coupling multi-functionality within the multi-chambered mesoporous na …

Hatemongers ride on echo chambers to escalate hate speech diffusion.
Goel V, Sahnan D, Dutta S, Bandhakavi A, Chakraborty T. Goel V, et al. PNAS Nexus. 2023 Feb 8;2(3):pgad041. doi: 10.1093/pnasnexus/pgad041. eCollection 2023 Mar. PNAS Nexus. 2023. PMID: 36926221 Free PMC article.
We observe that this cohesion is far from mere organized behavior; instead, in these networks, hatemongers dominate the echo chambers-groups of users actively align themselves to specific ideological positions. The observed dominance of hateful users to inflate information …

The ontogeny of choanocyte chambers during metamorphosis in the demosponge Amphimedon queenslandica.
Sogabe S, Nakanishi N, Degnan BM. Sogabe S, et al. Evodevo. 2016 Mar 8;7:6. doi: 10.1186/s13227-016-0042-x. eCollection 2016. Evodevo. 2016. PMID: 26958337 Free PMC article.
Moreover, cell proliferation assays demonstrate that, following the initial formation of choanocyte chambers, chambers grow at least partially by the proliferation of choanocytes within the chamber, although recruitment of individual cells into established …

Reliable cell retention of mammalian suspension cells in microfluidic cultivation chambers.
Schmitz J, Stute B, Täuber S, Kohlheyer D, von Lieres E, Grünberger A. Schmitz J, et al. Sci Rep. 2023 Mar 8;13(1):3857. doi: 10.1038/s41598-023-30297-5. Sci Rep. 2023. PMID: 36890160 Free PMC article.
Here, we present an easy-to-implement cell retention concept to withhold cells inside microfluidic cultivation chambers. By introducing a blocking structure into a cultivation chamber's entrance and nearly closing it, cells can be manually pushed into the …

Comparison of different counting chambers using a computer-assisted semen analyzer.
Peng N, Zou X, Li L. Peng N, et al. Syst Biol Reprod Med. 2015;61(5):307-13. doi: 10.3109/19396368.2015.1063175. Epub 2015 Jul 27. Syst Biol Reprod Med. 2015. PMID: 26214093
To evaluate the accuracy and precision of the different types of counting chambers for human semen analysis in combination with a computer-assisted semen analyzer (CASA), a quality-control study that compared human sperm analysis results obtained using different counting …

Acute Angle-Closure Glaucoma.
Khazaeni B, Zeppieri M, Khazaeni L. Khazaeni B, et al. 2023 Nov 26. In: StatPearls [Internet]. Treasure Island (FL): StatPearls Publishing; 2025 Jan–. 2023 Nov 26. In: StatPearls [Internet]. Treasure Island (FL): StatPearls Publishing; 2025 Jan–. PMID: 28613607 Free Books & Documents.
Aqueous humor is produced in the ciliary body, passes through the pupil, and drains through the trabecular meshwork (TM) and Schlemm canal at the anterior chamber's angle. In ACAG, IOP increases rapidly due to outflow obstruction of the aqueous humor. The main predi …

Cross-sectional imaging findings of cardiac outpouchings.
Ufuk F, Hazirolan T. Ufuk F, et al. Diagn Interv Radiol. 2023 Jan 31;29(1):68-79. doi: 10.4274/dir.2022.221419. Epub 2023 Jan 2. Diagn Interv Radiol. 2023. PMID: 36960184 Free PMC article. Review.
A cardiac outpouching (CO) is a protrusion in a heart chamber's internal anatomical lining. Most COs are clinically insignificant, but some are of vital importance, requiring immediate surgery. ...
