Titin Is Present in the Elastic Tethers That Connect Separating Anaphase Chromosomes in Crane‐Fly Spermatocytes

Cytoskeleton, EarlyView.
ABSTRACT Elastic tethers connect telomeres of separating chromosomes in anaphase of animal cells. Immunofluorescence staining of titin in crane‐fly spermatocytes, using 4 different antibodies, shows that the giant elastic protein titin seems to be a component of mitotic tethers: titin “strands” extend between separating chromosomes, connecting their ...

Evaluation of Ceftriaxone as a Monotherapy and Amoxicillin With Clavulanic Acid as Combination Therapy in Surgical Prophylaxis

iNew Medicine, EarlyView.
ABSTRACT Surgical antibiotic prophylaxis (SAP) is crucial in preventing postoperative surgical site infections (SSIs), especially in clean and clean‐contaminated surgeries. It was a prospective comparative observational study that compared the effectiveness and safety of single‐dose ceftriaxone monotherapy with amoxicillin–clavulanic acid as a ...

Coat colour in marsupials: genetic variants at the ASIP locus determine grey and black fur of the brushtail possum

Royal Society Open Science
The possession of fur or hair is a defining characteristic of mammals and can occur in a variety of colours and patterns. While genetic determinants of coat colour are well described in eutherian ‘placental’ mammals, the other major mammalian infraclass,

The evolution, distribution and diversity of endogenous circoviral elements in vertebrate genomes [PDF]

, 2018
Circoviruses (family Circoviridae) are small, non-enveloped viruses that have short, single-stranded DNA genomes. Circovirus sequences are frequently recovered in metagenomic investigations, indicating that these viruses are widespread, yet they remain ...

Application of Principal Component Analysis and Probabilistic Neural Networks in Ferralsols Recovery Evaluation Through Planting of Mabea Fistulifera and Eucalyptus Urograndis

Land Degradation &Development, EarlyView.
ABSTRACT This study presents an innovative assessment model for analyzing the evolution of degraded soils subjected to different reclamation strategies. The proposal combines statistical and artificial intelligence tools to jointly integrate multiple physical and chemical soil properties, allowing for a more synthetic view of the processes.

Anatomy of the heart and coronary blood supply of the white-eared opossum (Didelphis albiventris) [PDF]

Arquivo Brasileiro de Medicina Veterinária e Zootecnia
Although the white-eared opossum is frequently observed in both rural and urban environments, there is little anatomical knowledge about this marsupial species. To our knowledge, there are no descriptions of its heart anatomy. Thus, the aim of this study

The interplay between landscape change and plasticity in habitat selection determines dispersal movements and settlement in small non‐flying vertebrates

Oikos, EarlyView.
The response of dispersers to landscape changes depends on both external environmental conditions and individual internal conditions, as well as movement and orientation abilities. Plasticity in habitat selection may also affect how individuals respond to landscape changes.

Quantitative micro‐XRF combined with X‐ray imaging reveals correlations between Zn concentration and dentin tubule porosity across entire teeth

VIEW, EarlyView.
The combination of calibrated micro‐CT and quantitative micro‐XRF measurement facilitates the correlation of density and composition in the 3D macro‐structure of teeth. Zn concentration in dentin increases by a factor of 10 toward the pulp. Incidentally, the overall density decreases, showing an association between Zn and the dentin tissue porosity ...
