Ovarian Torsion.
Guile SL, Mathai JK. Guile SL, et al. 2023 Jul 17. In: StatPearls [Internet]. Treasure Island (FL): StatPearls Publishing; 2024 Jan–. 2023 Jul 17. In: StatPearls [Internet]. Treasure Island (FL): StatPearls Publishing; 2024 Jan–. PMID: 32809510 Free Books & Documents.
Ovarian torsion is a process that occurs when the ovary twists over the ligaments that support it in the adnexa. The fallopian tube often twists with the ovary and is then referred to as adnexal torsion. ...The ovary has dual blood supply from the ovarian arteries a …

Eshelby untwisting.
Zhong X , Zhou H , Li C , Shtukenberg AG , Ward MD , Kahr B . Zhong X , et al. Chem Commun (Camb). 2021 Jun 7;57(45):5538-5541. doi: 10.1039/d1cc01431e. Epub 2021 May 7. Chem Commun (Camb). 2021. PMID: 33960341
The concept of Eshelby untwisting, the effect of an axial screw dislocation driving an intrinsically twisted nanocrystal towards a straighter configuration more consistent with long-range translational symmetry, is introduced here. ...For rods built from the P3(2)21 enanti …

Light's twist.
Padgett M. Padgett M. Proc Math Phys Eng Sci. 2014 Dec 8;470(2172):20140633. doi: 10.1098/rspa.2014.0633. Proc Math Phys Eng Sci. 2014. PMID: 25484612 Free PMC article. Review.
However, the energy and momentum flow within light beams can twist to form vortices such as eddies in a stream. These twists carry angular momentum, which can make microscopic objects spin, be used to encode extra information in communication systems, enable the des …

The quantum twisting microscope.
Inbar A, Birkbeck J, Xiao J, Taniguchi T, Watanabe K, Yan B, Oreg Y, Stern A, Berg E, Ilani S. Inbar A, et al. Nature. 2023 Feb;614(7949):682-687. doi: 10.1038/s41586-022-05685-y. Epub 2023 Feb 22. Nature. 2023. PMID: 36813895
Here, we demonstrate a conceptually new type of scanning probe microscope-the quantum twisting microscope (QTM)-capable of performing local interference experiments at its tip. ...Through a series of experiments, we demonstrate room-temperature quantum coherence at the tip …

Twist response of actin filaments.
Bibeau JP, Pandit NG, Gray S, Shatery Nejad N, Sindelar CV, Cao W, De La Cruz EM. Bibeau JP, et al. Proc Natl Acad Sci U S A. 2023 Jan 24;120(4):e2208536120. doi: 10.1073/pnas.2208536120. Epub 2023 Jan 19. Proc Natl Acad Sci U S A. 2023. PMID: 36656858 Free PMC article.
Actin cytoskeleton force generation, sensing, and adaptation are dictated by the bending and twisting mechanics of filaments. Here, we use magnetic tweezers and microfluidics to twist and pull individual actin filaments and evaluate their response to applied loads. …

Moiré metasurfaces for dynamic beamforming.
Liu S, Ma S, Shao R, Zhang L, Yan T, Ma Q, Zhang S, Cui TJ. Liu S, et al. Sci Adv. 2022 Aug 19;8(33):eabo1511. doi: 10.1126/sciadv.abo1511. Epub 2022 Aug 17. Sci Adv. 2022. PMID: 35977023 Free PMC article.
Here, we introduce an entirely different approach-moire metasurfaces-to implement dynamic beamforming through mutual twists of two closely stacked metasurfaces. The superposition of two high-spatial-frequency patterns produces a low-spatial-frequency moire pattern through …

Twist-stretch relations in nucleic acids.
Zoli M. Zoli M. Eur Biophys J. 2023 Nov;52(8):641-650. doi: 10.1007/s00249-023-01669-6. Epub 2023 Jun 25. Eur Biophys J. 2023. PMID: 37357224
Nucleic acids are highly deformable helical molecules constantly stretched, twisted and bent in their biological functioning. Single molecule experiments have shown that double stranded (ds)-RNA and standard ds-DNA have opposite twist-stretch patterns and stretching …

Capillary-Induced Hair Twist.
Kovanko L, Tawfick S. Kovanko L, et al. Langmuir. 2019 Oct 15;35(41):13421-13426. doi: 10.1021/acs.langmuir.9b01441. Epub 2019 Oct 1. Langmuir. 2019. PMID: 31532682
We investigate the self-assembly of hair-like fibers into twisted helices as they are pulled through the liquid interface at a controlled rate. Capillary-induced spontaneous fiber twisting phenomena are observed from the nano- to the millimeter scale. ...

Twisted arenes.
Wang KK. Wang KK. Top Curr Chem. 2014;349:31-61. doi: 10.1007/128_2012_361. Top Curr Chem. 2014. PMID: 22955509
The nonbonded steric interactions of substituents at the crowded C4 and C5 positions of phenanthrene cause the aromatic system to twist out of planarity. Similarly, the presence of substituents at the C1 and C12 positions of benzo[c]phenanthrene and at the C1 and C14 posit …

Modulating Strain in Twisted Pyrene-Fused Azaacenes.
Mateos-Martín J, Dhbaibi K, Melle-Franco M, Mateo-Alonso A. Mateos-Martín J, et al. Chemistry. 2023 Dec 11;29(69):e202302002. doi: 10.1002/chem.202302002. Epub 2023 Oct 25. Chemistry. 2023. PMID: 37682106
The design and synthesis of strained aromatics provide an additional insight into the relationship between structure and properties. In the last years, several approaches to twist pyrene-fused azaacenes have been developed that allow to introduce twists of different …
