The Importance of Frozen Section-Controlled Excision in Recurrent Basal Cell Carcinoma of the Eyelids

open access: yes, 2016
Objectives: To show the importance of frozen section-controlled excision to avoid the re-recurrence of recurrent basal cell carcinoma (BCC) of the eyelids. Materials and Methods: Thirty-five cases who underwent eyelid tumor excision in different centers

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

open access: yesFEBS 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 ...

Analysis of subbrow upper blepharoplasty by measuring the lid-to-brow distance [PDF]

open access: yesArchives of Aesthetic Plastic Surgery, 2019
Background Conventional upper blepharoplasty through a supratarsal incision is commonly performed for periorbital rejuvenation. However, the drawbacks of this technique include insufficient removal of lateral hooding and an unnatural postoperative ...

Congenital upper eyelids ectropion in Down’s syndrome

open access: yes, 2017
Congenital bilateral ectropion of the upper eyelids is a rare, benign condition reported in ophthalmic literature. It is more frequently associated with Down’s syndrome, ichthyosis, and sporadic cases in newborns from black population.

Dimethyl fumarate combined with cisplatin at subcytotoxic doses sensitizes cervical cancer toward ferroptosis and apoptosis through GSH restriction and p53 (re)activation

open access: yesMolecular Oncology, EarlyView.
Dimethyl fumarate (DMF) reduces growth of HPV‐positive cervical cancer spheroids and induces ferroptosis in cervical cancer cells via blocking SLC7A11/Glutathione (GSH) axis. Combination of subcytotoxic doses of DMF and cisplatin (CDDP) further suppresses spheroid growth and drives cell death in 2D culture models.

Limited retromuscular fibrofatty tissue resection in upper blepharoplasty for senile patients [PDF]

open access: yesArchives of Aesthetic Plastic Surgery, 2019
Background Studies of eyelid anatomy suggest an absence of supratarsal folds and a redundancy of retromuscular tissue in many Asians. Aggressive retromuscular tissue resection during senile blepharoplasty can lead to complications such as hematoma and ...

The Various Ways in Which Birds Blink

open access: yesAnimals, 2023
There has, to date, been no systematic study of the various ways in which birds blink. Digital video recordings were made, and studied using still frames, of 524 bird species, mainly in zoos but also in the wild.

Mycobacterial cell division arrest and smooth‐to‐rough envelope transition using CRISPRi‐mediated genetic repression systems

open access: yesFEBS Open Bio, EarlyView.
CRISPRI‐mediated gene silencing and phenotypic exploration in nontuberculous mycobacteria. In this Research Protocol, we describe approaches to control, monitor, and quantitatively assess CRISPRI‐mediated gene silencing in M. smegmatis and M. abscessus model organisms.

C2α‐carbanion‐protonating glutamate discloses tradeoffs between substrate accommodation and reaction rate in actinobacterial 2‐hydroxyacyl‐CoA lyase

open access: yesFEBS Open Bio, EarlyView.
Enzymes of the 2‐hydroxyacyl‐CoA lyase group catalyze the condensation of formyl‐CoA with aldehydes or ketones. Thus, by structural adaptation of active sites, practically any pharmaceutically and industrially important 2‐hydroxyacid could be biotechnologically synthesized. Combining crystal structure analysis, active site mutations and kinetic assays,
