We describe a new harlequin frog (genus Atelopus) from the cloud forest near Anchihuay (Anco District, Ayacucho Department) from 2000 to 2150 m elevation in southern Peru, representing the first record for the genus in the Department of Ayacucho. The new species has a maximum snout-vent length of 21.5 mm in females and 21.6 mm in males, and resembles A. erythropus in general appearance, small size, and dorsal coloration. The new species can be distinguished from A. erythropus by its unique pattern of ventral coloration, dorsal skin texture, and snout shape. We detected the presence of the pathogenic fungus Batrachochytrium dendrobatidis in individuals of the new species. This pathogen is threatening the survival of harlequin frogs throughout the Neotropics. In addition to chytridiomycosis, habitat loss further threatens the single locality where the new species is known to occur.

Background: Urinary incontinence (UI), which can be classified as stress, urgency, or mixed, represents a public health problem that mainly affects adult women. This study aimed to determine the prevalence, association of sociodemographic and obstetric factors with the types of UI as well as the perceived impact on quality of life of women attending primary health facilities in the Tacna region from Peru.
Methods: A quantitative, non-experimental, correlational, and cross-sectional study was conducted.

Article Synopsis
- Blood-based biomarkers like p-tau217 are being studied for their effectiveness in diagnosing Alzheimer's disease (AD), but previous research has mainly focused on non-Hispanic White populations, leading to a knowledge gap across different ethnic backgrounds.
- A new study involving Peruvians, including mestizos and indigenous groups, examined plasma p-tau217 in 525 individuals, revealing significant associations between the biomarker and AD, especially in those with the APOE-e4 allele, although it did not distinguish between healthy controls and mild cognitive impairment (MCI).
- The results indicated that p-tau217 levels correlated well with cognitive performance and had an impressive classification performance (ROC-AUC of 82.82%), marking a significant contribution to understanding AD in diverse
New evidence confirms the presence of the diamond stingray Hypanus dipterurus (Jordan & Gilbert 1880) in Chile and extends its southern range.

The diamond stingray (Hypanus dipterurus) is a species of cartilaginous fish that, according to the IUCN, is globally in a vulnerable state of conservation and its populations show a decline. New records of this ray species in southern Peru and northern Chile have expanded their known range. The species is distributed in the Eastern Central Pacific, from southern California to San Andres, on the central coast of Peru, but is poorly known in Chile.

Molecular genetic analyses are effective in revealing the origin, kinship, and genetic diversity of zoo animals. In this study, we carried out the genetic characterization of captive founder individuals of the South American fur seal (Arctocephalus australis) in Japanese zoos and aquariums based on analyses of mitochondrial sequences and nuclear microsatellite loci. In mitochondrial DNA analysis, the haplotype diversity and nucleotide diversity of the overall population were 0.

Article Synopsis
- - Cerebral coenurosis is a serious disease affecting sheep and goats globally, with a prevalence of 13.5% in Tanzania's Mpwapwa District, showing higher rates in goats (15.9%) compared to sheep (4.8%).
- - A study identified key risk factors linked to the origins of the animals, particularly in certain areas like Chipogoro and Iwondo.
- - Knowledge among sheep and goat keepers about the disease is low, especially regarding infection cycles and zoonotic potential, emphasizing the need for improved education and control measures in livestock management.
