An approach for coherent periodogram averaging of tilt‐series data for improved contrast transfer function estimation

open access: yesFEBS Open Bio, EarlyView.
The contrast transfer function (CTF) is an imaging aberration that is a major resolution‐limiting factor in cryo‐electron microscopy (cryo‐EM). Precise CTF estimation is key to overcoming this limitation, but is particularly challenging in cryo‐electron tomography (cryo‐ET) data. Here, we present an approach for using geometric information to assist in

Monopoles and Solitons in Fuzzy Physics

open access: yes, 1999
Monopoles and solitons have important topological aspects like quantized fluxes, winding numbers and curved target spaces. Naive discretizations which substitute a lattice of points for the underlying manifolds are incapable of retaining these features ...

GDP‐fucose transporter SLC35C1: a potential regulatory role in cytosolic GDP‐fucose and fucosylated glycan synthesis

open access: yesFEBS Open Bio, EarlyView.
The inactivation of SLC35C1 (GDP‐fucose transporter) and enzymes involved in GDP‐fucose biosynthesis was studied. Fucose supplementation increases the level of GDP‐fucose to abnormal, millimolar values in the absence of the TSTA3 protein and SLC35C1 in contrast to the GMDS/SLC35C1 double mutant.

Matrix: a complex amalgam of structures and functions in tumor microenvironment

open access: yesFEBS Open Bio, EarlyView.
The matrix is a dynamic, intricate three‐dimensional mesh of biomolecules with both structural and functional properties. This review deals with the complexity of this ‘molecular amalgam’ in the tumor microenvironment and highlights its importance in the maintenance and evolution of tumors by describing certain matrix biomolecules, such as ...

The Gravity of Cartoon Physics; or, Schrödinger’s Coyote

open access: yesELOPE, 2018
When Wile E. coyote goes off a cliff, instead of falling in a parabolic arc, he comes to a halt in mid-air, hangs there until he realizes that he is no longer on solid ground, then falls. Many critics and, indeed, the creators of the cartoons themselves,

Preparation and characterization of renal cell peptides from fetal rats for their antitumor activity

open access: yesFEBS Open Bio, EarlyView.
This study aimed to prepare renal cells (RCs) from fetal rats which were digested by enzymes. Candidate peptides RCPs were characterized by capillary HPLC and MS and their bioactivity was predicted using peptideranker. The predicted top 10 bioactive peptides were synthesized.

F-theory on quotients of elliptic Calabi-Yau threefolds

open access: yesJournal of High Energy Physics, 2019
In this work we consider quotients of elliptically fibered Calabi-Yau threefolds by freely acting discrete groups and the associated physics of F-theory compactifications on such backgrounds.
