N-Embedded Cubarene: A Quadrangular Member of the Macrocycle Family.
Zhang H, Li H, Sun S, Tan L, Shen H, Lin B, Yang P. Zhang H, et al. Org Lett. 2023 Mar 31;25(12):2078-2083. doi: 10.1021/acs.orglett.3c00442. Epub 2023 Mar 22. Org Lett. 2023. PMID: 36946503
Despite the large number of synthetic macrocycles, the cubarenes, the quadrangular-shaped macrocyclic arenes, remain less investigated, possibly due either to synthetic challenges or to the lack of suitable building blocks. ...

Artificial chordae for degenerative mitral valve disease: critical analysis of current techniques.
Ibrahim M, Rao C, Athanasiou T. Ibrahim M, et al. Interact Cardiovasc Thorac Surg. 2012 Dec;15(6):1019-32. doi: 10.1093/icvts/ivs387. Epub 2012 Sep 7. Interact Cardiovasc Thorac Surg. 2012. PMID: 22962321 Free PMC article. Review.
The use of artificial chordae provides an alternative to the techniques pioneered by Carpentier (including the quadrangular resection, transfer of native chordae and papillary muscle shortening/plasty), which can be more technically difficult. Despite a growth in their upt …

Outcomes of mitral valve repair using artificial chordae.
Ibrahim M, Rao C, Savvopoulou M, Casula R, Athanasiou T. Ibrahim M, et al. Eur J Cardiothorac Surg. 2014 Apr;45(4):593-601. doi: 10.1093/ejcts/ezt421. Epub 2013 Aug 29. Eur J Cardiothorac Surg. 2014. PMID: 23990619 Review.
OBJECTIVES: The use of artificial chordae techniques has increased the number of mitral valve lesions which are amenable to repair. Artificial chordae can be adapted for a wide range of mitral valve pathologies including restricting the motion of overly mobile 'floppy' Bar …

A Quadrangular Flap Technique for Vermilion Repair in Unilateral Cleft Lip.
Masuoka H. Masuoka H. Plast Reconstr Surg Glob Open. 2017 May 25;5(5):e1346. doi: 10.1097/GOX.0000000000001346. eCollection 2017 May. Plast Reconstr Surg Glob Open. 2017. PMID: 28607867 Free PMC article.
In this article, we herein report a modified technique for vermilion repair that is focused on the labial tubercle. The muco-vermilion quadrangular flap was elevated from the lateral lip to augment the labial tubercle. ...In conclusion, the quadrangular flap can be …

Different surgical treatments for nasal septal perforation and their outcomes.
Goh AY, Hussain SS. Goh AY, et al. J Laryngol Otol. 2007 May;121(5):419-26. doi: 10.1017/S002221510700566X. Epub 2007 Jan 25. J Laryngol Otol. 2007. PMID: 17250780 Review.
RESULTS: Five studies examined the sole use of intranasal mucosal flaps to close the perforation, i.e. inferior turbinate flaps, quadrangular cartilage flap and mucoperiosteal flap. Eighteen studies reported the use of a combination of intranasal mucosal flap and interposi …

A DNA nanopillar as a scaffold to regulate the ratio and distance of mimic enzymes for an efficient cascade catalytic platform.
Kou BB, Chai YQ, Yuan YL, Yuan R. Kou BB, et al. Chem Sci. 2020 Oct 22;12(1):407-411. doi: 10.1039/d0sc03584j. Chem Sci. 2020. PMID: 34168746 Free PMC article.
Initially, the ratio of mimic enzyme AuNPs (glucose oxidase-like activity) and hemin/G-quadruplex DNAzyme (peroxidase-like activity) fixed at the designed position was adjusted by changing the number of edges in a DNA polyhedron, resulting in an optimal mimic enzyme ratio …

Preliminary pharmacognostic screening of Achyranthes coynei stem.
Upadhya V, Ankad GM, Pai SR, Hegde SV, Hegde HV. Upadhya V, et al. J Ayurveda Integr Med. 2015 Apr-Jun;6(2):134-8. doi: 10.4103/0975-9476.159076. J Ayurveda Integr Med. 2015. PMID: 26167003 Free PMC article.
Perennial, shrubby nature and woody stem were the distinguishing morphological characters observed. Transverse section (TS) illustrated quadrangular outline of the stem and showed the presence of two types of trichomes on the thick-walled epidermis. TS also showed numbe …

Anatomical considerations for nerve transfer in axillary nerve injury.
Kim SJ, Bang JH, Yang HJ, Moon SH, Choi YR, Lee HY. Kim SJ, et al. Sci Rep. 2024 Jan 13;14(1):1262. doi: 10.1038/s41598-024-51923-w. Sci Rep. 2024. PMID: 38218996 Free PMC article.
The axillary nerve divided anteriorly and posteriorly before passing the quadrangular space in all specimens, with specific distances to the first ramifications. ...The longest and thickest branches of the radial nerve to the triceps muscles were identified, with no statis …

Variability in attachment of the coracoacromial ligament in relation with its morphology.
Alraddadi A, Alashkham A, Lamb C, Soames R. Alraddadi A, et al. Surg Radiol Anat. 2017 Dec;39(12):1323-1330. doi: 10.1007/s00276-017-1900-5. Epub 2017 Jul 22. Surg Radiol Anat. 2017. PMID: 28735412
MATERIALS AND METHODS: The CAL was investigated in 220 cadaveric shoulders from 58 males and 59 females, with a median age of 82 years (range 53-102 years). CALs were classified according to three factors: (1) number of bands present; (2) shape; and (3) attachment to the a …

The anti-Kekule number of G is the smallest cardinality of anti-Kekule sets and is denoted by ak(G) . ...As a consequence, we prove that if G H1 , then ak(G) = 4 ; moreover, if G H2 , we give the condition to judge that the anti-Kekule number of graph G is 4 or 5... …
