Association of phenotypic traits and fertility in Holstein heifers: Body condition score, body weight, antral follicle count, Anti-Müllerian hormone, and anogenital distance.

The aim of this cross-sectional observational study was to assess whether nulliparous Holstein heifer fertility is associated with (1) energy reserve-related traits, such as body condition score (BCS) and body weight (BW); (2) ovarian reserve-related traits, such as Anti-Müllerian hormone (AMH) and antral follicle count (AFC); and (3) development-related traits, such as anogenital distance (AGD) and vulval length (VUL). From August 2022 through July 2023, we used a prospective approach in which the phenotypic traits (BCS, AMH, AFC, AGD, BW, and VUL) of 698 Holstein heifers were measured once at approximately 12 mo of age (at the beginning of the breeding program). All heifers were submitted to the herd reproductive management from 367 ± 3 d of age and 297 kg of BW until 570 d of age, or 5 breedings.

Ayahuasca reverses ischemic stroke-induced neuroinflammation and oxidative stress.

Background: Ischemic stroke is a leading cause of death and disability worldwide. Survivors face disability and psychiatric sequelae resulting from ischemia-induced cell death and associated neuroinflammation, and oxidative stress. Herbal medicines have been shown to elicit neuroprotective effects following stroke due to their anti-inflammatory and antioxidant effects.

Genomes of Galápagos Mockingbirds Reveal the Impact of Island Size and Past Demography on Inbreeding and Genetic Load in Contemporary Populations.

Restricted range size brings about noteworthy genetic consequences that may affect the viability of a population and eventually its extinction. Particularly, the question if an increase in inbreeding can avert the accumulation of genetic load via purging is hotly debated in the conservation genetic field. Insular populations with limited range sizes represent an ideal setup for relating range size to these genetic factors.

Retinal Vasculitis as a Rare Presentation of Microscopic Polyangiitis.

Microscopic polyangiitis (MPA) is a rare, autoimmune, small-vessel vasculitis usually described with the presence of perinuclear antineutrophil cytoplasmic antibodies (p-ANCA). It encompasses a broad spectrum of clinical features, including fatigue, weight loss, fever, arthralgia, skin lesions, and involvement of the lungs or kidneys. Ocular manifestations, however, are extremely rare.

Occurrence and management of thrombosis recurrence and bleeding in low-molecular-weight heparin-treated patients with cancer-associated thrombosis: a French nationwide cohort study.

Background: Rates of venous thromboembolism (VTE) recurrence and bleeding remain high in patients with cancer who are prescribed anticoagulants (ACs) such as low-molecular-weight heparin (LMWH) after an initial VTE event.

Objectives: To identify patient characteristics associated with VTE recurrence and bleeding in patients receiving LMWH for cancer-associated VTE and to explore secondary AC management and clinical outcomes in these patients.

Methods: An observational study was conducted using nationwide French data for adults with active cancer who were hospitalized with VTE in 2013-2018 and were reimbursed for LMWH ≤ 30 days after hospital discharge.
