Article Synopsis
  • The median artery usually disappears after two months of fetal development but can persist into adulthood, sometimes associated with variations like a bifid median nerve.
  • A cadaver study revealed a unique case with bilateral persistent median arteries (PMA) and a bifid median nerve, as well as an unusual origin and path for the palmar cutaneous branch of the median nerve (PCBMN).
  • Dissection of a 45-year-old male cadaver showed that the PMA arose from the ulnar artery, leading to differing branching patterns in the hands, and highlighted the importance of recognizing these variations for understanding carpal tunnel syndrome and surgical risks.

Since the developmental stage of oocyte is a challenging issue in the success of vitrification, this study investigated the effects of vitrification, before and after in vitro maturation, on the survival and maturation rates, developmental competence and the expression levels of genes involved in apoptosis, oxidative stress and epigenetic modifications. Mouse germinal vesicle (GV) oocytes were divided into four groups: fresh in vitro matured oocytes without vitrification (fIVM), in vitro matured oocytes after vitrification (vIVM), in vitro matured oocytes before vitrification (IVMv). In addition, in vivo matured oocytes (MII) were used as control.

Crocin, the main biologically active carotenoid of saffron, generally is derived from the dried trifid stigma of L. Many studies have demonstrated that crocin has several therapeutic effects on biological systems through its anti-oxidant and anti-inflammatory properties. The wide range of crocin activities is believed to be because of its ability to anchor to many proteins, triggering some cellular pathways responsible for cell proliferation and differentiation.

It is well established that maternal lifestyle during pregnancy and lactation affects the intrauterine programming of F1 offspring. However, despite the co-use of alcohol and nicotine is a common habit, the effects of exposure to both substances on the reproductive system of F1 male offspring and the underlying mechanisms of developmental programming have not been investigated. The present study aimed to examine pre- and postnatal concurrent exposure to these substances on genetic and epigenetic alterations of sperm cells as well as testis properties of F1 offspring compared with exposure to each substance alone.
