Herbivory‐Induced Stomatal Opening Triggers the Dispersal of an Invasive Insect Herbivore

Advanced Science, EarlyView.
The invasive leafminer Phthorimaea absoluta uniquely manipulates plant defenses by inducing stomatal opening in tomato. This response, mediated by the stomatal regulator IQM1, enhances the release of the repellent volatile benzaldehyde. This volatile triggers the dispersal of adult moths, facilitates colonization of new hosts, and leads to rapid ...

Three Members of the 6-cys Protein Family of Plasmodium Play a Role in Gamete Fertility [PDF]

, 2010
The process of fertilization is critically dependent on the mutual recognition of gametes and in Plasmodium, the male gamete surface protein P48/45 is vital to this process.

The impact of obesity on male fertility [PDF]

Hormones, 2015
Obesity in men of reproductive age is globally on the increase. There is clear evidence from epidemiological studies that obesity impacts negatively on male fertility; it is associated with hypogonadism, although it is less consistently linked to impaired spermatogenesis and tests of sperm function, including DNA fragmentation.

An Injectable ROS‐Responsive Nanozyme Hydrogel Regulates the Uterine Microenvironment to Prevent Intrauterine Adhesions

Advanced Science, EarlyView.
The injectable CeTA@GPP hydrogel is administered via intrauterine injection, forming a protective barrier. In the high ROS inflammatory microenvironment of injured endometrium, boronate ester cleavage triggers responsive CeTA release and local enrichment.

TFR for males in Denmark: Calculation and tempo-correction

Demographic Research, 2015
Background: Studies of trends and tempo corrections of fertility have focused on female rather than male fertility; one reason being that the necessary detailed data are more widely available for mothers than for fathers.

TECTB Variants Reveal Tectorial Membrane Vulnerability in Dominant Non‐Syndromic Hearing Loss

Advanced Science, EarlyView.
TECTB is a non‐collagenous protein of the tectorial membrane – an extracellular matrix of the cochlea. This study identifies dominant missense variants in TECTB linked to human hereditary deafness in two unrelated families. Genetically engineered mice homozygous for one of the variants are profoundly deaf, whereas heterozygous mice have normal hearing ...

From stress signals to fertility challenges: the role of damage-associated molecular patterns in male reproduction

Frontiers in Immunology
Male infertility is influenced by genetic abnormalities, hormonal imbalances, lifestyle factors, and environmental exposures. Recently, Damage-Associated Molecular Patterns (DAMPs) have emerged as key players in male reproductive health, particularly in ...

Prion‐Like Protein LENG8‐Mediated Nucleation Drives Stress Granule Assembly

Advanced Science, EarlyView.
LENG8 is a newly identified stress granule (SG) nucleator required for SG assembly. Following stress, nuclear LENG8 granules disassemble, allowing LENG8 to translocate into the cytoplasm and form independent nucleation foci. These foci fuse with canonical early G3BP1/TIA1 seeds via LENG8‐TIA1 binding to drive SG maturation.
