Divergent Effects of Capsid Proteins on Type I Interferon Signaling.

Viruses in the family can infect mammals and birds. Porcine circovirus type 2 (PCV2) significantly affects the livestock industry by causing porcine circovirus-associated diseases, such as postweaning multisystem wasting syndrome, respiratory disease complex, and dermatitis nephropathy syndrome. Additionally, beak and feather disease virus in parrots, canine circovirus in dogs, and columbid circovirus (pigeon circovirus) in racing pigeons induce immunosuppression, followed by secondary infections in these hosts.

Transcriptome-wide RNA 5-methylcytosine profiles of human iPSCs and iPSC-derived cardiomyocytes.

Cardiac regenerative therapy has recently progressed by reprogramming somatic cells into induced pluripotent stem cells (iPSCs) and advanced by large-scale differentiation-derived cardiomyocytes (hiPSC-CMs). However, repairing damaged cardiac tissues with hiPSC-CMs remains limited due to immune rejection, cardiac arrhythmias, and concerns over tumor formation after hiPSC-CM transplantation. Despite efforts in profiling epigenomic changes during cardiac differentiation, regulatory mechanisms underlying 5-methylcytosine (mC) deposition in RNA mC epitranscriptomic landscape during hiPSC-to-cardiomyocyte differentiation remain unclear.

Clinical outcomes of round spermatid injection vs intracytoplasmic sperm injection: The role of hormonal pretreatment for nonobstructive azoospermia.

Background: Round spermatid injection (ROSI) into oocytes offers men with nonobstructive azoospermia (NOA) the opportunity to have biological offspring in cases where mature spermatozoa are not detected. However, the clinical outcomes of ROSI remain poor. This study compared the outcomes of ROSI with intracytoplasmic sperm injection (ICSI) and investigated the effect of hormonal pretreatment.

A feasibility study on predicting cow calving time over 40 h in advance using heart rate and financial technical indicators.

In dairy farming, the uncertainty of cow calving date often imposes waiting costs for days on farmers. Improving the accuracy of calving date prediction would mitigate these costs, specifically before a few days of the event. We monitored and analyzed the heart rate patterns of eight pregnant cows in the days leading up to calving using a dedicated monitoring device.

Comparison of behavioral and physiological changes in postpartum healthy and inflammatory diseased cows.

During parturition, cows often experience intense pain and stress, which increases the risk of inflammatory diseases. This study aimed to compare the postpartum health status between healthy cows and those diagnoses with inflammatory diseases by examining behavioral and heart rate (HR) variability (HRV) changes, to provide information before the onset of disease. Eight Holstein cows were used in this study.

Effects of SGLT2 Inhibitors with and without Metformin in High-Risk, Treatment-Naïve Patients with Diabetes.

Contemporary evidence supports the cardiovascular and renal benefits of sodium-glucose co-transporter-2 inhibitors (SGLT2is) in patients with diabetes. While metformin has traditionally been recommended as a first-line treatment, its exact role in improving cardiovascular outcomes remains uncertain. This study aims to evaluate the impact of combination therapy with metformin on the cardiovascular and renal outcomes in high-risk, treatment-naïve diabetic patients who have undergone SGLT2i therapy.

Progesterone in Pregnancy: Evidence-Based Strategies to Reduce Miscarriage and Enhance Assisted Reproductive Technology.

The incidence of miscarriage in early pregnancy, between 5-20 weeks, is common, with a prevalence of between 5-22% of all pregnancies. Miscarriage can have physical, social, and mental health impacts on women and their families. In societies such as Taiwan, where the birth rate is falling and life expectancy is increasing, there is concern that factors that reduce birth rates will have detrimental economic and societal effects.

Heart rate variability and behavioral alterations during prepartum period in dairy cows as predictors of calving: a preliminary study.

Objective: Parturition is crucial for dams, their calves, and cow managers. The prediction of calving time, which assists cow managers to decide on the relocation of cows to maternity pens and necessity of human supervision, is a pivotal aspect of livestock farming. However, existing methods of predicting calving time in dairy cows based on hormonal changes and clinical symptoms are time-consuming and yield unreliable predictions.

Right Ventricular-Vascular Uncoupling Predicts Pulmonary Hypertension in Clinically Diagnosed Heart Failure With Preserved Ejection Fraction.

Background: Pulmonary hypertension (PH) is highly prevalent in patients with heart failure with preserved ejection fraction (HFpEF), and it is a strong predictor of adverse outcomes. We aimed to determine possible echocardiographic parameters to predict the presence of PH in patients with HFpEF.

Methods And Results: A total of 113 patients with HFpEF were prospectively enrolled from November 2017 to July 2022.

Magnetic field induced dose effects in radiation therapy using MR-linacs.

MR-guided radiotherapy (MRgRT) is one of the most significant advances in radiotherapy in recent years. The hybrid systems were designed to visualize patient anatomical and physiological changes during the course of radiotherapy, enabling more precise treatment. However, before MR-linacs reach their full potential in delivering safe and accurate treatments to patients, the radiotherapy team must understand how a magnetic field alters the dosimetric properties of the radiation beam and its potential impact on treatment quality and clinical outcomes.

Feasibility of repeat microdissection testicular sperm extraction within 6 months for nonobstructive azoospermia.

Background: Microdissection testicular sperm extraction (mTESE) is the mainstay of sperm retrieval in men with nonobstructive azoospermia (NOA). Some experts believe that a resting period of ≥6 months is required between procedures to ensure better sperm retrieval rates and fewer complications. However, no scientific studies have investigated how long patients should wait before arranging a second mTESE procedure.

Clinical implementation of kVCT-guided tomotherapy with ClearRT.

A helical fan-beam kilovoltage computed tomography (kVCT) was recently introduced into Tomotherapy units. This study aims to share the initial experience of kVCT in clinical workflow, compare its performance with that of the existing megavoltage computed tomography (MVCT), and explore its potential in adaptive planning. We retrospectively enrolled 23 patients who underwent both MVCT and kVCT scans.

Reproductive-age patients with breast cancer have safe options when choosing a type of fertility preservation method to be applied.

Effects on skin dose from unwanted air gaps under bolus in an MR-guided linear accelerator (MR-linac) system.

Bolus is commonly used in MV photon radiotherapy to increase superficial dose and improve dose uniformity for treating shallow lesions. However, irregular patient body contours can cause unwanted air gaps between a bolus and patient skin. The resulting dosimetric errors could be exacerbated in MR-Linac treatments, as secondary electrons generated by photons are affected by the magnetic field.
