The evolution of sperm morphometry in pheasants [PDF]

open access: yes, 2007
Postcopulatory sexual selection is thought to be a potent evolutionary force driving the diversification of sperm shape and function across species. In birds, insemination and fertilisation are separated in time and sperm storage increases the duration

Morphometric Shape Analysis with Measurement Covariance Estimates [PDF]

open access: yesProcedings of the British Machine Vision Conference 2011, 2011
We propose a shape analysis system based upon the description of landmarks with measurement covariance, which extends statistical linear modelling processes to ‘pseudo landmarks’ for scientific studies. We discuss the properties of our approach and how measurement covariances can be considered characteristic of the local shape. Our formulation includes

Differentiation of Trichuris species using a morphometric approach [PDF]

open access: yes, 2019
Trichuris trichiura is a nematode considered as the whipworm present in humans and primates. The systematics of the genus Trichuris is complex. Morphological studies of Trichuris isolated from primates and humans conclude that the species infecting these

Craniofacial Morphometric Measurements of Children with Celiac Disease

open access: yesIranian Journal of Pediatrics, 2019
Objectives: To examine the craniofacial morphologic features of children with celiac disease and to investigate the presence of specific features in this disease. Methods: Totally 100 celiac patients between the ages of 3 and 17 years who were diagnosed with celiac disease by biopsy and 100 healthy age- and sex-matched children were included in the ...

Advances in horse morphometric measurements using LiDAR

open access: yesComputers and Electronics in Agriculture, 2020
Zoometric measurements have a potential value in differentialing between individuals and within populations. The measurement of body size in horses and livestock plays a significant role in functional longevity, production, and reproductive performance and health.

Morphometric, meristics and comparative studies of Chrysichthys nigrodigititus (Lacepede) from Lagos Lekki and Badagry Lagoons, Lagos State, south west Nigeria [PDF]

open access: yes, 2005
Morphometric measurements, meristic counts and comparative studies of Chrysicthys nigrodigitatus samples from Lagos, Lekki, and Badagry Lagoons was carried out to determine the amount of variation among the species from the different locations using ...

Asymmetric ephaptic inhibition between compartmentalized olfactory receptor neurons. [PDF]

open access: yes, 2019
In the Drosophila antenna, different subtypes of olfactory receptor neurons (ORNs) housed in the same sensory hair (sensillum) can inhibit each other non-synaptically.

Discovery and Targeted Proteomic Studies Reveal Striatal Markers Validated for Huntington's Disease

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Clinical trials for Huntington's disease (HD) enrolling persons before clinical motor diagnosis (CMD) lack validated biomarkers. This study aimed to conduct an unbiased discovery analysis and a targeted examination of proteomic biomarkers scrutinized by clinical validation. Methods Cerebrospinal fluid was obtained from PREDICT‐HD and

Biological compatibility between two temperate lineages of brown dog ticks, Rhipicephalus sanguineus (sensu lato) [PDF]

open access: yes, 2018
Background: The brown dog tick Rhipicephalus sanguineus (sensu stricto) is reputed to be the most widespread tick of domestic dogs worldwide and has also been implicated in the transmission of many pathogens to dogs and humans.
