Instanton Floer homology and the Alexander polynomial [PDF]

, 2010
The instanton Floer homology of a knot in the three-sphere is a vector space with a canonical mod 2 grading. It carries a distinguished endomorphism of even degree,arising from the 2-dimensional homology class represented by a Seifert surface.

Deciphering transcriptional plasticity in pancreatic ductal adenocarcinoma reveals alterations in sensory neuron innervation

Molecular Oncology, EarlyView.
Pancreatic sensory neurons innervating healthy and PDAC tissue were retrogradely labeled and profiled by single‐cell RNA sequencing. Tumor‐associated innervation showed a dominant neurofilament‐positive subtype, altered mitochondrial gene signatures, and reduced non‐peptidergic neurons.

Multi‐omics and low‐input proteomics profiling reveals dynamic regulation driving pluripotency initiation in early mouse embryos

FEBS Open Bio, EarlyView.
Mouse pre‐implantation development involves a transition from totipotency to pluripotency. Integrating transcriptomics, epigenetic profiling, low‐input proteomics and functional assays, we show that eight‐cell embryos retain residual totipotency features, whereas cytoskeletal remodeling regulated by the ubiquitin‐proteasome system drives progression ...

Suture versus tacker closure of the peritoneum in transabdominal preperitoneal repair of inguinal hernia: A prospective comparative cohort study

International Journal of Abdominal Wall and Hernia Surgery
BACKGROUND: Laparoscopic transabdominal preperitoneal repair of inguinal hernia (TAPP) is routinely done by general surgeons. (1) One crucial step is peritoneal closure post-mesh placement to prevent contact with the bowel.

3D (Bio) Printing Combined Fiber Fabrication Methods for Tissue Engineering Applications: Possibilities and Limitations

Advanced Functional Materials, EarlyView.
Biofabrication aims at providing innovative technologies and tools for the fabrication of tissue‐like constructs for tissue engineering and regenerative medicine applications. By integrating multiple biofabrication technologies, such as 3D (bio) printing with fiber fabrication methods, it would be more realistic to reconstruct native tissue's ...

Comparison of long-term stability among continuous, two-point, and transconjunctival buried suture methods in double-eyelid surgery: a 4-year retrospective cohort study of 1,500 cases [PDF]

Archives of Aesthetic Plastic Surgery
Background Double-eyelid surgery is a common aesthetic procedure, particularly among East Asian populations. However, long-term comparative data on different buried suture techniques remain limited. This study provides the first comprehensive three-group

Retained intrauterine sutures for 6 years

Gynecology and Minimally Invasive Therapy, 2020
The most common sutures used for uterine suturing during cesarean section (CS) are vicryl and/or chromic catgut. The sutures' chemistry and polymer morphology alter sutures' performance and absorption.

Morphological study of the skull sutures and their relationships to skull morphology in young camels (Camelus dromedarius)

Open Veterinary Journal, 2022
Objective: The sutures are associated with anatomical and physiological differences in skull camels. There is a deficiency in the information regarding the anatomy of dromedary camels, especially on fibrous joints (sutures) of the camels skull. Aim: The
