In order to assess the importance of the intensity of administration of chemotherapy in the management of advanced germ cell tumours we have calculated indices of chemotherapy. These have been used to compare the treatment given to patients who subsequently relapsed with matched controls who did not relapse. Two of these indices (alpha and beta) are derived from the doses of drugs whose dose is varied (cisplatinum, methotrexate and etoposide). These indices showed significant variation between cases and controls. Indices gamma and delta are derived from drugs whose dose is not varied. They showed no significant differences between the two groups. These results emphasise the importance of ensuring that patients with these curable cancers receive adequate doses of chemotherapy.

Expanding the Genetic Etiology of Multiple Morphological Abnormalities of the Sperm Flagella: A Case Report of Two Novel DNAH1 Variants.
S D Med
December 2024
Sanford Health Reproductive Medicine, Fargo, North Dakota.
Background: The following case report details the genetic evaluation and treatment of a 30-year-old male with a history of asthenoteratospermia and notable abnormalities of the sperm flagella.
Methods: Genetic evaluation was performed via a multi-gene panel of genes associated with primary ciliary dyskinesia and multiple morphological abnormalities of the sperm flagella (MMAF) prior to the couple's in vitro fertilization (IVF) cycle.
Results: Genetic evaluation was performed via a multi-gene panel of genes associated with primary ciliary dyskinesia and multiple morphological abnormalities of the sperm flagella (MMAF) prior to the couple's in vitro fertilization (IVF) cycle.
Transformation of sperm structure in Octopus vulgaris: From spermatogenesis to spermatophoric release.
PLoS One
January 2025
Department of Aqualife Medicine, Chonnam National University, Yeosu, Republic of Korea.
The present study describes the differentiation process of male germ cells in Octopus vulgaris, the morphology of sperm in the testis and spermatophore, and the sperm released after the spermatophoric reaction. During spermatogenesis, the male sperm cell gradually elongates from a round shape, with cytoplasm shifting toward the head and the acrosome forming. Additionally, in the spermatid stage, the flagellum develops within the posterior nuclear channel and extends outside the cytoplasm.

The purpose of this study was to improve the quality of frozen-thawed canine spermatozoa through the optimization of glycerol concentration (GC) and freezing rate in the semen freezing protocol. Ejaculates from nine dogs were diluted with an extender containing 0%, 1.5%, 3%, 6%, or 9% glycerol.

Brain and Mind Centre, The University of Sydney, Sydney, New South Wales, Australia.
Background: Parkinson's disease (PD) is the most common neurodegenerative movement disease. Human endogenous retroviruses (HERVs) are proviral remnants of ancient retroviral infection of germ cells that now constitute about 8% of the human genome. Under certain disease conditions, HERV genes are activated and partake in the disease process.

Department of Biochemistry and Molecular Biology, Michigan State University, East Lansing, Michigan, USA.
The TGF-β family ligand Nodal is an essential regulator of embryonic development, orchestrating key processes such as germ layer specification and body axis formation through activation of SMAD2/3-mediated signaling. Significantly, this activation requires the co-receptor Cripto-1. However, despite their essential roles in embryogenesis, the molecular mechanism through which Cripto-1 enables Nodal to activate the SMAD2/3 pathway has remained elusive.
