Evaluation of pregnancy associated glycoproteins assays for on farm determination of pregnancy status in beef cattle.

Transrectal ultrasonography is known as the gold standard for pregnancy detection, but requires costly equipment and technical skills; therefore, access to an inexpensive and more user-friendly method with similar accuracy could benefit cattle producers. Detection of pregnancy-associated glycoproteins can accurately determine pregnancy in ruminants; however, usually requires specialized equipment for the assay. Thus, the objectives of these studies were to 1) validate the IDEXX Alertys OnFarm Pregnancy Test (lateral flow) and compare the accuracy of all three commercial PAG assays to transrectal ultrasonography and 2) to determine the postpartum interval necessary for clearance of pregnancy-associated glycoproteins from the previous pregnancy to avoid false positives.

Evaluation of two beef cow fixed-time AI protocols that utilize presynchronization.

Presynchronization was evaluated as a method to improve estrus response before fixed-time AI (FTAI). The objective was to compare FTAI results in beef cows from two different presynchronization approaches. Blood samples were collected on Day -14 (Day 0 = CIDR removal) to determine progesterone concentration (≥1 ng/mL = high, <1 ng/mL = low).

A Transducing Bacteriophage Infecting Staphylococcus epidermidis Contributes to the Expansion of a Novel Siphovirus Genus and Implies the Genus Is Inappropriate for Phage Therapy.

The effort to discover novel phages infecting Staphylococcus epidermidis contributes to both the development of phage therapy and the expansion of genome-based phage phylogeny. Here, we report the genome of an S. epidermidis-infecting phage, Lacachita, and compare its genome with those of five other phages with high sequence identity.

Structural and Biochemical Characterization of Cysteine Desulfurase Complex SufSU.

In this work, we provide the first in vitro characterization of two essential proteins from (. ) involved in iron-sulfur (Fe-S) cluster biogenesis: the cysteine desulfurase SufS and the sulfurtransferase SufU. Together, these proteins form the transient SufSU complex and execute the first stage of Fe-S cluster biogenesis in the SUF-like pathway in Gram-positive bacteria.

Complete Genome Sequences of Five Phietaviruses Infecting Staphylococcus aureus.

The annotated whole-genome sequences of five cultured phietaviruses infecting Staphylococcus aureus are presented. They are closely related to prophages that were previously sequenced as part of S. aureus genomes.

Impact of trace mineral source on beef replacement heifer growth, reproductive development, and biomarkers of maternal recognition of pregnancy and embryo survival.

Trace minerals are known to play important roles in early embryo development. The study objective was to determine effects of trace mineral source on heifer reproductive performance. Beef heifers (n = 129) were randomly assigned to one of two treatments.

Mitochondrial dysfunction as a critical event in the pathophysiology of bipolar disorder.

The understanding of the pathophysiology of bipolar disorder (BD) remains modest, despite recent advances in neurobiological research. The mitochondrial dysfunction hypothesis of bipolar disorder has been corroborated by several studies involving postmortem brain analysis, neuroimaging, and specific biomarkers in both rodent models and humans. Evidence suggests that BD might be related to abnormal mitochondrial morphology and dynamics, neuroimmune dysfunction, and atypical mitochondrial metabolism and oxidative stress pathways.

Beliefs About the Influence of Rest During Concussion Recovery May Predict Activity and Symptom Progression Within an Active Duty Military Population.

Objectives: To evaluate relationships between beliefs about the impact of rest and the level of activities and symptoms over time among active duty Service members sustaining concussion, and whether these relationships vary by provision of concussion education.

Design: Longitudinal study using multilevel modeling to assess the relationship between beliefs about rest within 72 hours of concussion and change in activity and symptom level over time, as well as interaction by concussion education at the initial clinic visit.

Setting: Three military treatment facilities.

Accelerated aging in bipolar disorder: A comprehensive review of molecular findings and their clinical implications.

Bipolar disorder (BD) has been associated with clinical signs of accelerated aging, which potentially underlies its association with several age-related medical conditions, such as hypertension, metabolic imbalances, dementia, and cancer. This paper aims to comprehensively review evidence of biological aging in BD and explore findings and controversies related to common biological clocks in patients, including telomere length, DNA methylation, mitochondrial DNA copy number, inflammation, and oxidative stress. Our results suggest a complex interplay between biological markers and a potential key role of environmental factors, such as childhood trauma and psychological stress, in determining premature aging in patients.

Activity Level and Type During Post-acute Stages of Concussion May Play an Important Role in Improving Symptoms Among an Active Duty Military Population.

Previous research demonstrates that early rest and gradual increases in activity after concussion can improve symptoms; however, little is known about the intensity and type of activity during post-acute time periods-specifically months post-injury-that may promote optimal recovery in an active duty service member (SM) population. The objectives of this study were to investigate how activity level and type at the post-acute stages of concussion (at 1 and 3 month[s] post-injury) impact subsequent symptoms among SMs, and how this relationship might differ by the level of symptoms at the time of injury. Participants included 39 SMs ages 19-44 years from 3 military installations who were enrolled within 72 h after sustaining a concussion.

Activity Level During Acute Concussion May Predict Symptom Recovery Within an Active Duty Military Population.

Objective: To evaluate the impact on symptom resolution of activity acutely following a concussion and the role of acute-phase symptoms on this relationship among active duty service members (SMs).

Setting: Three military installations.

Participants: Sixty-two SMs aged 18 to 44 years who sustained a concussion within 72 hours of enrollment.

TSPO upregulation in bipolar disorder and concomitant downregulation of mitophagic proteins and NLRP3 inflammasome activation.

Bipolar disorder (BD) is a chronic, debilitating illness with a global prevalence of up to 4.8%. The importance of understanding how dysfunctional mitochondria and mitophagy contribute to cell survival and death in BD is becoming increasingly apparent.

Efficacy of the Mantram Repetition Program for Insomnia in Veterans With Posttraumatic Stress Disorder: A Naturalistic Study.

Statistics show that more than 80% of Veterans mention posttraumatic stress disorder (PTSD)-related symptoms when seeking treatment. Sleep disturbances and nightmares are among the top 3 presenting problems. Current PTSD trauma-focused therapies generally do not improve sleep disturbances.

Multi-site evaluation of a complementary, spiritually-based intervention for Veterans: The Mantram Repetition Program.

Background: Mental and physical symptoms affect Veterans' quality of life. Despite available conventional treatments, an increasing number of Veterans are seeking complementary approaches to symptom management. Research on the Mantram Repetition Program (MRP), a spiritually-based intervention, has shown significant improvements in psychological distress and spiritual well-being in randomized trials.
