Complete globozoospermia associated with PLCζ deficiency treated with calcium ionophore and ICSI results in pregnancy

Reproductive Biomedicine Online, 2009
Globozoospermia is an infrequent pathology in which spermatozoa lack acrosomes. Patients are considered sterile without IVF augmented with intracytoplasmic sperm injection (ICSI), as fertilization is impaired due to absence of oocyte activation.

Calcium/sodium exchange in purified secretory vesicles from bovine neurohypophyses [PDF]

, 1983
Purified secretory vesicles isolated from bovine neurohypophyses take up Na+ under the same circumstances where an efflux of Ca2+ takes place, suggesting a Na+/Ca2+ exchange. Potassium cannot substitute for Na+ in this process. Also, a Ca2+/Ca2+ exchange

Tropomyosin 1 Promotes Platelet Adhesion and Clot Contraction Separate from Its Roles in Developmental Hematopoiesis

Advanced Science, EarlyView.
ABSTRACT Genome‐wide association studies (GWAS) link the Tropomyosin 1 (Tpm1) locus to quantitative blood trait variation, but related mechanisms are unclear. Tpm1 encodes an actin‐binding protein that regulates actin filament diversity, cell adhesion, signaling, and actomyosin contractility.

Morphogenesis in the moss physcomitrella patens [PDF]

, 1993
A method was developed for recording the development of moss protonema using time-lapse video microscopy. This has provided a detailed record of the time-course of development from spore germination to the production of gametophores.

Multimodal Imaging Reveals Rapid Catecholamine Uptake and Release by Neutrophils

Advanced Science, EarlyView.
We show that immune cells (neutrophils) synthesize, uptake, and store catecholamine neurotransmitters such as dopamine or adrenaline. They also release them in response to specific stimuli (serotonin), which we directly visualize using fluorescent nanosensors. We further demonstrate that catecholamines affect neutrophil functions (NETosis) and platelet

TgCDPK3 is required for calcium ionophore-induced egress from host cells. [PDF]

, 2012
A) Mixing wild-type and ΔTgCDPK3 parasites shows knockout of TgCDPK3 causes T. gondii to be inefficient in ability to complete the lytic lifecycle in vitro, being effectively out-competed by wild-type by day 18 of the experiment.

Inhibitory effect of LY 255283 on the synthesis of leukotriene B4 and thromboxane A2 in human peripheral blood polymorphonuclear leukocytes and monocytes

Mediators of Inflammation, 1993
LY 255283 [(1-(5-ethyl-2-hydroxy-4-(6-methyl-6-)1H-tetrazol-5-yl)-heptyloxy) phenyl)ethanone], a specific leukotriene B4 (LTB4) receptor antagonist, inhibited the production of LTB4 in human peripheral blood polymorphonuclear leukocytes (PMNL) and in ...

Intracytoplasmic sperm injection with assisted oocyte activation resulting in successful pregnancies and live birth in couples with globozoospermia: A report of two cases

Journal of Human Reproductive Sciences, 2018
Globozoospermia, characterized by round-headed acrosomeless sperm, is a rare and severe form of teratozoospermia. We report a successful pregnancy in two cases of total globozoospermia after intracytoplasmic sperm injection (ICSI) with oocyte activation ...
