This study aims to investigate the gene expression of sperm-borne phospholipase C zeta ( PLCζ ), WW domain-binding protein 2N-Terminal Like ( WBP2NL ), and Tumor necrosis factor ( TNF-α ), as a negative control, in spermatozoa and their relationship with fertility and seminal quality in stallions. Ejaculates from 40 Criollo stallions were used, whose fertility was assessed on the basis of their pregnancy rate per cycle in at least two breeding seasons. Pregnancy rates ranged from 20% to 90% and were used to divide the stallions into two groups: High rates (≥ 50%) (n = 25), and Low rates (< 50%) (n = 15)...

The adnexa fetal tissues are sources of mesenchymal stromal cells (MSCs) due to their noninvasive harvest, with all biological material discarded most of the time. MSCs are a promise regarding to their plasticity, self-renewal, differentiation potentials, immunomodulatory and anti-inflammatory properties, which have made clinical stem cell therapy a reality. The present study aimed to characterize and evaluate the immunomodulation ability of bovine mesenchymal cells collected from bovine amniotic fluid (bAFMSCs) isolated and subjected to sixth consecutive culture passages in vitro ...

Steroids and gonadotrophins are essential for the regulation of late stages of preantral development and antral follicular development. Although the luteinizing hormone receptor (LHCGR) has been detected in the preantral follicles of rats, rabbits, and pigs, its expression, in bovine fetal ovary, has not been demonstrated. Based on this, we aimed to investigate the expression of the LHCGR and LHCGR mRNA binding protein ( LRBP ), as well as, to quantify bta-miR-222 (a regulatory microRNA of the LHCGR gene) during the development of bovine fetal ovary...

The CRISPR/Cas9 system is a simpler and more versatile method compared to other engineered nucleases such as Zinc Finger Nucleases (ZFNs) and Transcription Activator-Like Effector Nucleases (TALENs), and since its discovery, the efficiency of CRISPR-based genome editing has increased to the point that multiple and different types of edits can be made simultaneously. These advances in gene editing have revolutionized biotechnology by enabling precise genome editing with greater simplicity and efficacy than ever before...

A 75-year-old man with type 2 diabetes and a history of previous empyema surgery was admitted to our hospital due to difficulty moving caused by chronic obstructive pulmonary disease and dehydration. During the first two days of hospitalization, intestinal myiasis was diagnosed after maggots were found in his diapers. After the maggots disappeared, he developed a fever, prompting antibiotic therapy for a suspected secondary infection, resulting in clinical improvement. Despite thorough home cleaning, no flies or maggots were found, and the source of infection and the fly species remained unknown...

PURPOSE: This study investigated the factors associated with oral frailty among community-dwelling older adults. In particular, we compared the factors between individuals in the young-old and old-old groups and clarified the differences between the two groups. METHODS: We measured the basic attributes, body composition, grip strength, gait function, oral function, cognitive function, and daily living function using the Kihon checklist in older people living independently in T City, Aichi Prefecture...

INTRODUCTION: Few reports have described acyclovir (ACV) encephalopathy without acute kidney injury (AKI). OBJECTIVE: This study clarified the clinical features of ACV encephalopathy without AKI compared to that with AKI. METHODS: Creatinine (Cre) levels were measured on admission. After admission, Cre was measured in a timely manner for the first seven hospital days. The minimum Cre level in these measurements was then determined. ACV encephalopathy was defined when two criteria were met: 1) neurological symptoms appeared after valacyclovir (VACV) administration, and 2) neurological symptoms improved after VACV discontinuation...

AIM: This study aimed to verify whether working in cultivated land as a daily-life task contributes to the maintenance and improvement of physical and cognitive functions. METHODS: The participants were 91 elderly people of ≥65 years of age who owned cultivated land in the mountainous Koyadaira district in Tokushima Prefecture. Sex, age, body mass index (BMI), walking speed as a physical function, and the mini-mental status examination (MMSE) score as a cognitive function were measured and analyzed in addition to the total working hours per week (WH) in cultivated land...

OBJECTIVE: To examine the relationship between the dissatisfaction of family caregivers with diabetes treatment and depressive symptoms among the elderly. METHODS: The subjects were diabetic patients of 65 years of age or older and their family caregivers, who were outpatients at Ise Red Cross Hospital. The Japanese version of the Patient Health Questionnaire 9, which consists of nine items, was used to measure depressive symptoms. The Japanese version of the Treatment Satisfaction Scale for Caregivers of Dependent Diabetic Patients (STCD2 -J) was used to measure the satisfaction of family caregivers with diabetes treatment...

After the publication of the guidelines about the safe drug therapy for older people in 2015 by the Japan Geriatrics Society, the risk of polypharmacy has become popular. Older people are likely to have multimorbidity, resulting in the use of multiple drugs. This not only increases the frequency of side effects, but also increase confusion and difficulty in medication management and adherence. Polypharmacy is the problem related to these complicated drug therapies and will increase by age. It is necessary to review drugs and resolve polypharmacy without making comorbid conditions worth...

The epigenome can adequately regulate the on/off states of genes in response to external environmental factors and stress. In recent years, it has been observed that the epigenome, which is modulated through DNA methylation, histone modifications, and chromatin remodeling, changes with age. Alterations in the epigenome lead to the loss of cell-specific epigenome/identity, which in turn triggers a decline in tissue function. In mammals, postnatal epigenomic variations are not only caused by metabolic diseases, such as diabetes or DNA damage, but also by social stress and infectious diseases...
