Abstract

The concentrations of PAHs in seawater and sediments were measured at three selected sites (S1, S2, and S3) along the coastal area of Shandong (China) in April, May, and June, 2015, which ranged from 29.72 to 123.88 ng/L and 82.62 to 232.63 ng/g, respectively. Meanwhile, the reproductive toxicity...

Abstract

The spotted knifejaw (Oplegnathus punctatus) is a newly emerging fishery species inhabiting the Pacific Ocean around Hawaii, China, Japan and Korean Peninsula. Little information on the mechanism of gonadal development and gametogenesis in this species could be used for research and breeding work....

Abstract

In vitro embryo production through in vitro fertilization (IVF) using cryopreserved oocytes results to poor outcome due to the hardening of the zona pellucida during freezing. More recent in vitro fertilization alternative is the intracytoplasmic sperm injection (ICSI), which allows for the...

Abstract

In animals, when semen is discharged into the uterus, the seminal plasma carries the sperm to the egg. In plants, the function of pollen tube contents (PTC) is analogous to that of the seminal plasma in animals, i.e., carrying sperm cells to the ovules for fertilization. Because the function of the ...
