Reproductive outcomes of lactating dairy cows submitted to first timed artificial insemination protocols with different strategies to induce final ovulation.

The study evaluated strategies for induction of ovulation at the end of timed AI (TAI) protocols initiated after a novel presynchronization strategy. A total of 909 lactating dairy cows from 6 dairy herds initiated a presynchronization protocol on d -15 with an intravaginal progesterone (P4) implant and 7 d later (d -8) were treated with 1.0 mg of estradiol cypionate (EC) and 0.

Performance of SARC-F and SARC-CalF scores to predict risk of mortality in hemodialysis patients: a cohort study.

This study aimed to evaluate the association between the questionnaires SARC-F and SARC-CalF with risk of mortality in patients undergoing hemodialysis (HD). A cohort study, with patients on HD age ≥ 18 years, both sex, between June 2019 and April 2023. Body composition (anthropometry and bioelectrical impedance), muscle functional (handgrip strength and gait speed), screening of sarcopenia using the SARC-F and SARC-CalF, nutritional status and laboratory data were assessed.

Umbelliferone reduces inflammation and ligature-induced osteoclastic alveolar bone resorption in mice.

Aims: This study aimed to investigate the effects of Umbelliferone (UMB) on the inflammation underlying alveolar bone resorption in mouse periodontitis.

Methods: Male Swiss mice subjected to a ligature of molars were grouped as non-treated (NT), received UMB (15, 45, or 135 mg/kg) or saline daily for 7 days, respectively, and were compared with naïve mice as control. Gingival tissues were evaluated by myeloperoxidase (MPO) activity and interleukin-1β level by ELISA.

The role of dried blood spot tests in the detection of hepatitis B infection: A systematic review.

Hepatitis B remains a public health problem worldwide despite vaccine availability. Although the existing diagnostic tools help detect the infection, logistics support and limited resources and technologies affect their usefulness and reliability in developing countries. This systematic review evaluated the performance of dried blood spots (DBS) as a collection and storage tool for diagnosing an hepatitis B virus (HBV) infection.

Levodopa-Induced Pseudopheochromocytoma.

Unlabelled: Pseudopheochromocytoma is a pathological condition presenting with paroxysmal hypertension with normal or moderate elevation in catecholamines and metanephrine levels, but no evidence of a tumoural cause. Imaging studies and I-123 metaiodobenzylguanidine scintigraphy are essential for exclusion of pheocromocytoma. We describe a case of pseudopheochromocytoma related to levodopa in a patient with paroxysmal hypertension, headache, sweating, palpitations and increased plasmatic and urinary metanephrine levels, without adrenal or extra-adrenal tumour.
