Maternal gut microbiota‐derived daidzein prevents osteoporosis in female offspring following prenatal prednisone exposure

iMeta, EarlyView.
Prenatal prednisone therapy (PPT)/prenatal prednisone exposure (PPE) induces long bone dysplasia, reduced peak bone mass (PBM), and increased osteoporosis susceptibility in female offspring. Maternal gut microbiota metabolite daidzein (DAI) mediates PPE‐induced osteoporosis susceptibility in female adult offspring.

MOTILITY OF THE SPERMATOZOA IN THE EPIDIDYMIS. [PDF]

Journal of the American Medical Association, 1908
It has been taught that the spermatozoa do not acquire motility until after leaving the epididymes. This idea I have recently demonstrated to be erroneous. A young man had suffered from a double epididymitis years before the operation to be described.

Pyriproxyfen Disrupts the Ongoing Spermatogenesis Wave in Danio rerio Potentially Mediated by Voltage‐Dependent Calcium Channels and Protein Kinase C

Journal of Applied Toxicology, EarlyView.
ABSTRACT Pyriproxyfen (PPX) is an analog of the juvenile hormone from insects. Following our previous studies, for the ex vivo short‐term effect, we chose 10−9 M pyriproxyfen to analyze the morphology of spermatogenesis wave cells. In silico docking and ADMET (Absorption, Distribution, Metabolism, Excretion, Toxicity) studies were carried out to ...

Light and Electron Microscope Observations of the Male Reproductive Organs of Adult Julodis ehrenbergii Laporte (Coleoptera, Buprestidae)

Microscopy Research and Technique, EarlyView.
This study is about the male reproductive organs of Julodis ehrenbergii. To determine morphological and histological characters was used light and scanning electron microscopy were used. The investigation revealed testes, vasa deferentia, accessory glands, and ductus ejaculatorius structures.

Cryopreservation of Murine Spermatozoa [PDF]

ILAR Journal, 2000
Cryopreservation of mouse sperm provides an economic option for preserving the large number of mouse strains now being generated by transgenic and targeted mutation methodologies. The ability of a spermatozoan cell to survive cryobiological preservation depends on general biophysical constraints that apply to all cells, such as the avoidance or ...

Increasing acidification does not affect sexual reproduction of a solitary zooxanthellate coral transplanted at a carbon dioxide vent

Limnology and Oceanography, EarlyView.
Abstract The absorption of atmospheric carbon dioxide is causing significant changes to the carbonate chemistry of the ocean, in a phenomenon called ocean acidification. The latter makes it potentially more difficult for marine calcifiers like corals, to build their calcium carbonate structures, thus affecting their ability to survive and reproduce ...

A Neuromorphic Camera for Tracking Passive and Active Matter with Lower Data Throughput

Laser &Photonics Reviews, EarlyView.
The merits of an event‐based camera (EBC) for studies of passive and active matter are demonstrated. It is shown that it is possible to achieve results equivalent to those from an sCMOS camera while reducing data file sizes by up to two orders of magnitude.

Actin in Human Spermatozoa [PDF]

Biology of Reproduction, 1982
An actin-like material was extracted from human spermatozoa. The material comigrated with actin on sodium dodecylsulfate (SDS) polyacrylamide gel electrophoresis, and showed specific affinity for myosin. Purified anti-actin antibodies were used to localize actin to the posterior region of the sperm head and to the connecting piece, midpiece and ...

Smart Surface Engineering in Microcarriers: Toward Applications in Cancer Therapy

Macromolecular Materials and Engineering, EarlyView.
A microcarrier with dual surface modification integrates two distinct pH‐sensitive nanoreservoirs, enabling precise, site‐specific drug delivery and potential extracellular matrix degradation. This dual functionalization strategy ensures the separation of therapeutic functions, effectively preventing cross‐process interference and aiming synergistic ...

The Gold‐Maker of Animal Oil and Prussian Blue Fame — The Chemical and Medicinal Science Philosophy of Johann Conrad Dippel

The Chemical Record, EarlyView.
The radical Pietist Johann Conrad Dippel was a self‐proclaimed adept – a maker of gold and the philosophers’ stone. He was also a magister of theology, a doctor of medicine, and a self‐taught chemist, who coinvented the pigment Prussian Blue together with Johann von Diesbach, became known for his animal pyrolysis oil, his wonder‐wound balm, his ...
