Chromosomal disorders and male infertility [PDF]

, 2011
Infertility in humans is surprisingly common occurring in approximately 15% of the population wishing to start a family. Despite this, the molecular and genetic factors underlying the cause of infertility remain largely undiscovered.

Bacteria‐Derived Extracellular Vesicle as A “Trojan Horse” for Selective M1 Macrophage‐Targeting in A Multi‐Cellular Entanglement Environment

Advanced Functional Materials, EarlyView.
The temporary transition of macrophages from a pro‐inflammatory phenotype of macrophages (M1) to an anti‐inflammatory phenotype of macrophages (M2) is crucial for tissue repair and regeneration processes. Bacterial outer membrane vesicles (OMVs) are utilized as a “trojan horse” for specific M1 macrophage‐targeting and anti‐inflammatory drug delivery ...

Increased adaptability to rapid environmental change can more than make up for the two-fold cost of males [PDF]

, 2018
The famous "two-fold cost of sex" is really the cost of anisogamy -- why should females mate with males who do not contribute resources to offspring, rather than isogamous partners who contribute equally? In typical anisogamous populations, a single very fit male can have an enormous number of offspring, far larger than is possible for any female or ...

Exploring Literature for Conceptualisations of Male Infertility: A Phenomenological Analysis [PDF]

, 2018
Fathering a child is an important aspect of the identity of a man as motherhood is for a woman. Male factor infertility is one reason for the inability to father a child and this can contribute to many issues for a man at a personal or societal level ...

Stable, Easy‐to‐Handle, Fully Autologous Electrospun Polymer‐Peptide Skin Equivalent for Severe Burn Injuries

Advanced Functional Materials, EarlyView.
A bioengineered skin equivalent composed of electrospun poly(ε‐caprolactone) (PCL) and the bioactive peptide Fmoc‐FRGD is developed for severe burn treatment. This scaffold promotes full‐thickness skin regeneration by supporting cellular adhesion and integration. In‐vitro and in‐vivo studies show enhanced mechanical stability, accelerated wound closure,

Magnetically Guided Mechanoactive Mineralization Scaffolds for Enhanced Bone Regeneration

Advanced Functional Materials, EarlyView.
A 3D‐printed ‘rebar‐concrete’ inspired scaffold (PGS‐P@MGel) synergizes spontaneous biomineralization with magneto‐mechanical stimulation through PDA@Fe3O4‐embedded hydrogel. This dual biointerface activates Piezo1/β‐catenin/YAP mechanotransduction axis, enhancing BMSCs osteogenesis and angiogenesis simultaneously.

Male Infertility is a Women\u27s Health Issue-Research and Clinical Evaluation of Male Infertility Is Needed [PDF]

, 2020
Infertility is a devastating experience for both partners as they try to conceive. Historically, when a couple could not conceive, the woman has carried the stigma of infertility; however, men and women are just as likely to contribute to the couple\u27s

Supramolecular Zwitterionic Hydrogels for Information Encryption, Soft Electronics and Energy Storage at Icy Temperature

Advanced Functional Materials, EarlyView.
A series of ACHPES‐based hydrogels are developed and realizing multiple functions like anti‐fouling properties, alkali‐induced color/fluorescence‐changing ability and strain sensing. Furthermore, the hydrogels show excellent anti‐freezing performance, whose optical, mechanical and electrical properties remain stable at −47.3 °C.

Swimming against the tide: Gender bias in the physics classroom [PDF]

, 2017
This study examines physics students' evaluations of identical, video-recorded lectures performed by female and male actors playing the role of professors. The results indicate that evaluations by male students show statistically significant overall biases with male professors rated more positively than female professors.
