Summary: The taxonomy and phylogenetics of Neotropical deer have been mainly based on morphological criteria, but this study suggests a critical revision based on new molecular and cytogenetic markers. The analysis of satellite DNA revealed evolutionary relationships among the different Neotropical deer species, especially highlighting the high abundance of satellite DNA in Mazama species and its potential role in chromosomal rearrangements and ongoing speciation.

Summary: The study found that after cryopreservation of sperm from South American freshwater fish species, there was a significant increase in primary morphological abnormalities, while the percentage of normal cells did not change significantly. There was no significant change in the percentage of secondary abnormalities between fresh semen and cryopreserved semen.

Summary: Oligonucleotide (oligo)-fluorescence in situ hybridization (FISH) has become a new generation of FISH technique in plant molecular cytogenetics research. Chorus2 software effectively selects single-copy oligos, removes repetitive elements, and allows the development of FISH probes from plant species without an assembled genome, broadening its application in molecular cytogenetics research.

Summary: The study found that Acropora and massive Porites coral colonies exhibited significant differences in survival and growth after bleaching events, with Acropora showing a marked capacity for apparent recovery while massive Porites displayed stable survival. This contrast highlights different dynamics of boom-and-bust vs. protracted declines in the two major coral groups.

Summary: This study investigated the possibility of obtaining sperm from the endangered Hypancistrus zebra without hormonal induction, and found that hormonal treatment resulted in males releasing a higher volume of semen with higher quality. The use of exogenous hormones is crucial for controlling the reproductive cycle of fish species in captivity, especially for those facing extinction.

Summary: The study found that UroVysion was the most sensitive method, with all methods having high specificity. Cytology, forceps biopsies, and fine needle aspiration were also proven to have certain sensitivity and specificity for detecting malignancy in pancreatobiliary strictures. The most effective approach to maintaining high sensitivity while preserving specificity was limiting malignant interpretation to cases with 5+ cells showing the same polysomic signal pattern and/or loss of one or both 9p21 signals.

Summary: Somatic mosaicism is a known cause of neurological disorders, and this study reveals a novel mechanism for brain mosaicism through post-zygotic rescue of meiotic errors. The researchers found evidence of extra chromosome 1q allele in the brain tissue of patients with focal epilepsy, which was not observed in blood or buccal cells. This copy number gain was highly enriched in astrocytes and showed distinct gene expression signatures and hyaline inclusions.

Summary: This study investigated the dynamic changes in nucleosome occupancy and positioning in pronucleus-stage zygotes using a new method. The researchers found that nucleosomes were established more quickly in the paternal genome and were associated with specific transcription factor binding sites. These findings have important implications for understanding the mechanisms of chromatin remodeling after fertilization and key transcription regulators during development.

Summary: Deer species in the Neotropical region are experiencing population declines and decreased genetic diversity due to rapid habitat loss and human activities. Assisted reproductive technology (ART) shows promise in advancing wildlife conservation efforts and maintaining genetic diversity in deer. Techniques such as in vitro embryo production (IVP) and proteomics are being utilized to better understand and address reproductive challenges facing Neotropical deer.

Summary: The study investigated occupationally induced chromosomal damage in hospital personnel exposed to antineoplastic drugs and/or low doses of ionizing radiation. Both cytogenetic methods showed an increase in chromatid and chromosomal aberrations, as well as unstable aberrations, indicating recent exposure to genotoxic agents.

Summary: In this study, cytogenetic and molecular FISH techniques were used to investigate the chromosome morphology and rearrangements in an allotetraploid species of the sister subgenus Silurana. The results showed that the subgenomes of this species have distinctive characteristics, with one subgenome being more conserved and resembling a closely related diploid species, while the other subgenome evolves more rapidly and exhibits pronounced changes in chromosome structure.

Summary: This study aimed to evaluate minimally invasive protocols for estrus synchronization in the brown brocket deer. Different treatments were tested, and it was found that DIP, MGA 1x, and MGA 2x were effective in estrus synchronization, while the high dose of P4LA resulted in poor outcomes.

Summary: The present study aimed to test the efficiency of transcervical artificial insemination techniques with different methods of cervical immobilization in the brown brocket deer. The results showed that both TCAI-CI and TCAI-CT techniques were successful in achieving artificial insemination, regardless of using OT as a cervical dilation protocol. This method has a high success rate and applicability, and is beneficial for the conservation of deer species.

Summary: Monitoring the concentration of glucocorticoid metabolites (GCMs) in faecal samples is a non-invasive tool for evaluating stress in wild species. This study aimed to validate the use of GCM concentration as an indicator of adrenal activity and identify behavioural indicators of distress. Four male spotted pacas were subjected to an adrenocorticotropic hormone (ACTH) challenge-test, with changes in GCM concentration and behavioural indicators recorded. The results showed a peak in GCM concentration 24 hours after high-dose ACTH injection, and spotted pacas exhibited decreased exploration and feeding, as well as increased time in the inactive but awake state.

Summary: This study conducted an integrative assessment using morphological, cytogenetical, and molecular data to clarify the taxonomy of M. simplicicornis argentina. The results showed that the Argentinian gray brocket is actually the same species as the Paraguayan gray brocket, S. gouazoubira. The study used qualitative skull features, cranio-morphometric results, diploid chromosome number, and phylogenetic analysis to support this conclusion.

Summary: The Yucatan brown brocket deer, initially described as Mazama pandora, was repositioned to the genus Odocoileus based on mitochondrial DNA analysis. There is still a lack of consensus on the taxonomic classification of this species. This study aims to clarify the taxonomy of O. pandora using morphological, cytogenetic, and molecular data, and suggests that a new generic name should be indicated for this taxon.
