Cochrane RR, Brumwell SL, Shrestha A, Giguere DJ, Hamadache S, Gloor GB, Edgell DR, Karas BJ.
PMID: 33114477
Biology (Basel). 2020 Oct 26;9(11). doi: 10.3390/biology9110358.

Algae are attractive organisms for biotechnology applications such as the production of biofuels, medicines, and other high-value compounds due to their genetic diversity, varied physical characteristics, and metabolic processes. As new species are being domesticated, rapid nuclear and organelle...

Moving the ER tip by tip.

Developmental cell

Nguyen HH, Farías GG.
PMID: 34932946
Dev Cell. 2021 Dec 20;56(24):3305-3306. doi: 10.1016/j.devcel.2021.12.001.

Endoplasmic reticulum (ER) and microtubule (MT) interactions have been observed in different cell types. However, how these interactions are regulated remains unknown. In this issue of Developmental Cell, Nourbakhsh et al. show that an ER-localized kinase, TAOK2, catalyzes the...

Switching the Reactivity of Palladium Diimines with "Ancillary" Ligand to Select between Olefin Polymerization, Branching Regulation, or Olefin Isomerization.

Angewandte Chemie (International ed. in English)

Jones GR, Basbug Alhan HE, Karas LJ, Wu JI, Harth E.
PMID: 32986896
Angew Chem Int Ed Engl. 2021 Jan 18;60(3):1635-1640. doi: 10.1002/anie.202012400. Epub 2020 Nov 09.

Coordinating solvents are commonly employed as ancillary ligands to stabilize late transition metal complexes and are conventionally considered to have little effect on the reaction products. Our work identifies that the presence of ancillary ligand in Pd-diimine catalyzed polymerizations...

Pain-Suppressed Behaviors in the Red-tailed Hawk (.

Applied animal behaviour science

Mazor-Thomas JE, Mann PE, Karas AZ, Tseng F.
PMID: 24904190
Appl Anim Behav Sci. 2014 Mar 01;152:83-91. doi: 10.1016/j.applanim.2013.12.011.

Our ability to provide analgesia in wild and exotic patients is hampered by a lack of species-specific information on effective drugs and protocols. One contributing factor is the difficulty of applying data from traditional laboratory tests of nociception to...

The role of epigenetics in psychological resilience.

The lancet. Psychiatry

Smeeth D, Beck S, Karam EG, Pluess M.
PMID: 33915083
Lancet Psychiatry. 2021 Jul;8(7):620-629. doi: 10.1016/S2215-0366(20)30515-0. Epub 2021 Apr 27.

There is substantial variation in people's responses to adversity, with a considerable proportion of individuals displaying psychological resilience. Epigenetic mechanisms are hypothesised to be one molecular pathway of how adverse and traumatic events can become biologically embedded and contribute...

On the reciprocal relationship between σ-hole bonding and (anti)aromaticity gain in ketocyclopolyenes.

Organic & biomolecular chemistry

Paudel HR, Karas LJ, Wu JI.
PMID: 32601633
Org Biomol Chem. 2020 Jul 15;18(27):5125-5129. doi: 10.1039/d0ob01076f.

σ-Hole bonding interactions (e.g., tetrel, pnictogen, chalcogen, and halogen bonding) can polarize π-electrons to enhance cyclic [4n] π-electron delocalization (i.e., antiaromaticity gain) or cyclic [4n + 2] π-electron delocalization (i.e., aromaticity gain). Examples based on the ketocyclopolyenes: cyclopentadienone, tropone,...

Phase behavior and design rules for plastic colloidal crystals of hard polyhedra via consideration of directional entropic forces.

Soft matter

Karas AS, Dshemuchadse J, van Anders G, Glotzer SC.
PMID: 31169283
Soft Matter. 2019 Jul 10;15(27):5380-5389. doi: 10.1039/c8sm02643b.

Plastic crystals - like liquid crystals - are mesophases that can exist between liquids and crystals and possess some of the characteristic traits of each of these states of matter. Plastic crystals exhibit translational order but orientational disorder. Here,...

Liquid Nitrogen Cryotherapy in Recalcitrant Alopecia Areata: A Study of 11 Patients.

International journal of trichology

Zawar VP, Karad GM.
PMID: 27127370
Int J Trichology. 2016 Jan-Mar;8(1):15-20. doi: 10.4103/0974-7753.179403.

CONTEXT: Recalcitrant alopecia areata (AA) is not uncommon in clinical practice. In certain patients, treatment failures are known with almost every conventional therapy either singly or in combination.AIMS: To study the efficacy of liquid nitrogen (LN) cryotherapy in patients...

A rare case of acute epiglottitis due to Staphylococcus aureus in an adult.

Infectious disease reports

Harris C, Sharkey L, Koshy G, Simler N, Karas JA.
PMID: 24470933
Infect Dis Rep. 2012 Jan 02;4(1):e3. doi: 10.4081/idr.2012.e3. eCollection 2012 Jan 02.

Epiglottitis has been mainly associated with childhood infection with Haemophilis influenzae type B but cases of adult epiglottitis are increasing. We report here a case of adult epiglottitis and present evidence that it was caused by Staphylococcus aureus. A...

Comparison of the effect of medical assistants versus certified athletic trainers on patient volumes and revenue generation in a sports medicine practice.
