The sigma-hole revisited.
Politzer P, Murray JS, Clark T, Resnati G. Politzer P, et al. Phys Chem Chem Phys. 2017 Dec 13;19(48):32166-32178. doi: 10.1039/c7cp06793c. Phys Chem Chem Phys. 2017. PMID: 29199313
A covalently-bonded atom typically has a region of lower electronic density, a "sigma-hole," on the side of the atom opposite to the bond, along its extension. ...This positive potential reflects not only the lower electronic density of the sigma-hole but als …

The pi-hole revisited.
Politzer P , Murray JS , Clark T . Politzer P , et al. Phys Chem Chem Phys. 2021 Aug 12;23(31):16458-16468. doi: 10.1039/d1cp02602j. Phys Chem Chem Phys. 2021. PMID: 34286761
These are molecular regions of low electronic density that are perpendicular to planar portions of the molecular frameworks. pi-Holes often have positive electrostatic potentials associated with them, which result in mutually polarizing attractive forces with negative site …

Intramolecular hole-transfer in protonated anthracene.
Laws BA, Krechkivska O, Nauta K, Kable SH, Schmidt TW. Laws BA, et al. Phys Chem Chem Phys. 2023 Jul 26;25(29):19524-19531. doi: 10.1039/d3cp02922k. Phys Chem Chem Phys. 2023. PMID: 37462442
This work reveals that the excitation of protonated anthracene induces a symmetry-breaking intramolecular charge-transfer process along a Marcus-Hush coordinate, where the positively charged hole hops from the central bridging sp(2) carbon, onto one of the aromatic …

Functional and protective hole hopping in metalloenzymes.
Gray HB, Winkler JR. Gray HB, et al. Chem Sci. 2021 Sep 27;12(42):13988-14003. doi: 10.1039/d1sc04286f. eCollection 2021 Nov 3. Chem Sci. 2021. PMID: 34760183 Free PMC article. Review.
When one of the reactants is a strong oxidant, it is convenient to consider the movement of a positively charged "hole" in a direction opposite to that of the electron. Hole hopping along chains of tryptophan (Trp) and tyrosine (Tyr) residues is a critical fu …

Critical cell wall hole size for lysis in Gram-positive bacteria.
Mitchell GJ, Wiesenfeld K, Nelson DC, Weitz JS. Mitchell GJ, et al. J R Soc Interface. 2013 Jan 9;10(80):20120892. doi: 10.1098/rsif.2012.0892. Print 2013 Mar 6. J R Soc Interface. 2013. PMID: 23303219 Free PMC article.
Here, we develop and analyse a biophysical theory of the response of a Gram-positive cell's membrane to the formation of a hole in the cell wall. ...Together, the theory and experiments provide a means to quantify the mechanisms of death of Gram-positive cell …

Positive-hole correction of multiple-jet impactors for collecting viable microorganisms.
Macher JM. Macher JM. Am Ind Hyg Assoc J. 1989 Nov;50(11):561-8. doi: 10.1080/15298668991375164. Am Ind Hyg Assoc J. 1989. PMID: 2688387
The observed number of colonies can be adjusted for the probability that more than one viable particle was collected through a sampling hole and merged with other microorganisms at an impaction site to produce a single colony. A "positive-hole" correction tab …

Anatomy of pi-hole bonds: Linear systems.
Scheiner S. Scheiner S. J Chem Phys. 2021 Nov 7;155(17):174302. doi: 10.1063/5.0067570. J Chem Phys. 2021. PMID: 34742196
The list of sigma-hole bonds is long and growing, encompassing both H-bonds and its closely related halogen, chalcogen, etc., sisters. ...Quantum calculations are applied to study such pi-hole bonds that involve linear molecules, whose positive region is a ci …

Black Hole Solutions as Topological Thermodynamic Defects.
Wei SW, Liu YX, Mann RB. Wei SW, et al. Phys Rev Lett. 2022 Nov 4;129(19):191101. doi: 10.1103/PhysRevLett.129.191101. Phys Rev Lett. 2022. PMID: 36399744
In this Letter, employing the generalized off-shell free energy, we treat black hole solutions as defects in the thermodynamic parameter space. The results show that the positive and negative winding numbers corresponding to the defects indicate the local thermodyna …

[Progress in the treatment of refractory macular hole by human amniotic membrane].
Wang QH, Yan H. Wang QH, et al. Zhonghua Yan Ke Za Zhi. 2022 Jun 11;58(6):467-471. doi: 10.3760/cma.j.cn112142-20211115-00541. Zhonghua Yan Ke Za Zhi. 2022. PMID: 35692031 Review. Chinese.
The surgery of refractory macular hole is often very tough for its uncertain prognosis. There is no unified definition for refractory macular hole, which usually refers to macular hole with a long duration, large diameter, or failure of initial operation. ... …

Positive dysphotopsia after intrascleral intraocular lens fixation: a case report.
Mito T, Kawakami H, Ikoma T, Ukai Y, Tsuchiya M, Kubo E, Sasaki H. Mito T, et al. BMC Ophthalmol. 2022 Jun 11;22(1):263. doi: 10.1186/s12886-022-02474-z. BMC Ophthalmol. 2022. PMID: 35690806 Free PMC article.
We attempted surgical closure of the PI hole, resulting in the complete disappearance of positive dysphotopsia. CONCLUSIONS: A PI hole created during intrascleral IOL fixation may cause postoperative positive dysphotopsia depending on the position of t …
