The muscular branching patterns of the ulnar nerve in fetal forearms.

Objective: We aimed to present our findings systematically by examining the muscular branching patterns of the ulnar nerve (UN) in the forearms of fetuses.

Methods: This study was conducted on the 52 forearms of 26 formalin-fixed fetal cadavers with gestational ages varying between 19 and 37 weeks. The anatomical dissection was performed by using stereomicroscope with × 8 magnification.

Dry Mouth Caused by Facial Nerve Ischemia due to Subarachnoid Hemorrhage: An Experimental Study.

Objective: Parasympathetic network damage results in facial nerve damage, sublingual ganglion degeneration, sublingual gland dysfunction, and dry mouth. In this study, subarachnoid hemorrhage (SAH) was considered to be the cause of dry mouth.

Methods: We assessed 23 hybrid rabbits, including 5 control (group 1, Control).

Narrating the journey of sustained recovery from substance use disorder.

Background: The reported high rate of relapse in the context of an ever-increasing rate of substance abuse internationally and in South Africa together with the fact that the topic of sustained recovery from Substance Use Disorder (SUD) appears to be totally neglected in extant literature and research agendas motivated the researchers to conduct this investigation. The aim was to obtain an in-depth understanding of how individuals recovering from a SUD experience and sustain their recovery in order to fill the gap in the knowledge base.

Methods: A qualitative research approach was followed, employing a narrative and phenomenological research design alongside an explorative, descriptive and contextual strategy of inquiry.

137 ancient human genomes from across the Eurasian steppes.

For thousands of years the Eurasian steppes have been a centre of human migrations and cultural change. Here we sequence the genomes of 137 ancient humans (about 1× average coverage), covering a period of 4,000 years, to understand the population history of the Eurasian steppes after the Bronze Age migrations. We find that the genetics of the Scythian groups that dominated the Eurasian steppes throughout the Iron Age were highly structured, with diverse origins comprising Late Bronze Age herders, European farmers and southern Siberian hunter-gatherers.
