Ethnomedicinal Uses, Phytochemistry, Pharmacological Activities, and Toxicology of the Subfamily Gomphrenoideae (Amaranthaceae): A Comprehensive Review

open access: yesChemistry &Biodiversity, EarlyView.
ABSTRACT The subfamily Gomphrenoideae is composed of about 480 accepted species, many of which have been historically used as medicinal plants, reason why they have been studied in terms of chemical profile, biological activity, and safety. This review consolidates the advances in research on this subfamily over the past 47 years, emphasizing its ...

Assessing the Sensitivity of Different Life Stages for Sexual Disruption in Roach (Rutilus rutilus) Exposed to Effluents from Wastewater Treatment Works [PDF]

open access: yes, 2005
Surveys of U.K. rivers have shown a high incidence of sexual disruption in populations of wild roach (Rutilus rutilus) living downstream from wastewater treatment works (WwTW), and the degree of intersex (gonads containing both male and female structural

Mammalian Tolerance to Amino Acid Heterochirality

open access: yesChemBioChem, Accepted Article.
Organisms use amino acids predominantly in l‐configuration. On the other hand, a series of studies show that a variety of d‐amino acids also occur in mammals and amino acid homochirality is not complete. Mammals de novo synthesize most amino acids with l‐configuration, but serine and aspartate are converted from l‐ to d‐configuration by endogenous ...

The Oxidized Ti2(Al/Sn)C Behavior as Anode for Lithium‐ and Sodium‐Ion Batteries: The Role of the MAX Phase Order

open access: yesChemElectroChem, EarlyView.
The present study is dedicated to investigation of the performance of oxidized Ti2(Al/Sn)C system (211 MAX phases) as anode for lithium and sodium ion batteries. Their behavior has been rationalized as function of the tin content and as function of the MAX phase order, with detailed comparison with the 312 MAX phase analog series.

Timing in the Testis [PDF]

open access: yesJournal of Biological Rhythms, 2015
The testis provides not just one but several models of temporal organization. The complexity of its rhythmic function arises in part from its compartmentalization and diversity of cell types: not only does the testis produce gametes, but it also serves as the major source of circulating androgens. Within the seminiferous tubules, the germ cells divide

Myosin VI Is Associated With the Endoplasmic Reticulum in Regions of Sertoli Cells Containing Tubulobulbar Complexes

open access: yesCytoskeleton, EarlyView.
ABSTRACT Myosin VI has been reported by others to localize in association with various regions of apical tubulobulbar complexes (TBCs) at sites of attachment between Sertoli cells and late spermatids in the mouse. Tubulobulbar complexes internalize “intact” intercellular junctions during sperm release and during spermatocyte translocation through the ...

TRiC Is a Structural Component of Mammalian Sperm Axonemes

open access: yesCytoskeleton, EarlyView.
ABSTRACT The TRiC chaperonin is responsible for folding ~5%–10% of the proteome in eukaryotic cells. Our recent cryo‐electron microscopy studies of axonemes from diverse mammalian cell types led to the surprising discovery that a fully assembled TRiC chaperonin is a structural component of mammalian sperm flagella, where it is tethered to the radial ...

Phosphorylation at the Helm: Kinase‐Mediated Regulation of Primary Cilia Assembly and Disassembly

open access: yesCytoskeleton, EarlyView.
ABSTRACT The primary cilium serves as an antenna of most vertebrate cells and is important for conveying cues from several signaling pathways into appropriate cellular responses during development and homeostasis. Cilia assembly and disassembly processes are thought to be strictly controlled; however, the precise nature of molecular events underlying ...

Population studies on gerbils of the western desert of Egypt, with special reference to Gerbillus andersoni DE Winton [PDF]

open access: yes, 1980
Population studies on the gerbil, Gerbillus andersoni, were carried out in Omayed in the Western Desert of Egypt during the period from July 1976 through August 1978 inclusive.

Biology and Management of Male‐Bodied Athletes in Elite Female Sports

open access: yesDrug Testing and Analysis, EarlyView.
Graphical representation of the relationships of transgender and XY DSDF as male‐bodied athletes along the binary dimensions of biological sex. ABSTRACT The physical advantages in elite power sports that allow men to surpass women are derived from the experience of male puberty.
