Spontaneous Uterine Leiomyoma Torsion: A Challenging Differential Diagnosis for Radiologists

European Journal of Case Reports in Internal Medicine, 2020
Uterine leiomyomas are very common gynaecological benign tumours. Spontaneous torsion of a uterine subserosal leiomyoma is a rare cause of acute lower abdominal pain and should be treated immediately with surgery.

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

FEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Study on initial fatigue damage of magnesium alloy under torsion and bending

Nihon Kikai Gakkai ronbunshu, 2015
Torsion and bending fatigue tests of magnesium alloy AZ31were carried out to investigate the initial damage under high cycle fatigue. The crystallographic orientation of crystals in which slip lines were occurred was analyzed by using electron back ...

A note on the torsion dependence of D-brane RR couplings [PDF]

, 2000
The dependence on the torsion H=db of the Wess-Zumino couplings of D-branes that are trivially embedded in space-time is studied. We show that even in this simple set-up some torsion components can be turned on, with a non-trivial effect on the RR ...

Chameleon sequences reveal structural effects in proteins representing micelle‐like distribution of hydrophobicity

FEBS Open Bio, EarlyView.
Amino acids sequence of two different proteins with the same sequence (chameleon sequence—black boxes) represent in 3D structure of the proteins different secondary structures: HHHH—helical and BBB—Beta‐structural. The chains folded in water environment adopt different III‐order structures in which the chameleon fragments appear to adopt similar status

Protein backbone and sidechain torsion angles predicted from NMR chemical shifts using artificial neural networks

Journal of Biomolecular NMR, 2013
A new program, TALOS-N, is introduced for predicting protein backbone torsion angles from NMR chemical shifts. The program relies far more extensively on the use of trained artificial neural networks than its predecessor, TALOS+.

Exon 7 splicing of ERα predicts poor prognosis and increases phenotypic heterogeneity in luminal a subtype breast cancer

FEBS Open Bio, EarlyView.
ERα splice variant ERα∆7 lacks the C‐terminus, and its expression may change phenotypes of breast cancers. Our results showed that ERα∆7 is found in the luminal A subtype, and elevated ERα∆7 levels are linked to improved cell survival with lower proliferation and migration.

Case Report: Adolescent epididymal cysts: three management approaches including a rare synchronous epididymal cyst and testicular torsion

Frontiers in Surgery
IntroductionEpididymal cysts are common benign lesions that typically present as painless scrotal masses. They predominantly occur in adult males but can also be found in adolescents, albeit with a higher likelihood of being overlooked at this age.

Statefinder diagnostic in a torsion cosmology

, 2009
We apply the statefinder diagnostic to the torsion cosmology, in which an accounting for the accelerated universe is considered in term of a Riemann-Cartan geometry: dynamic scalar torsion.
