Effect of middle-age plasma therapy on ileum morphology, immune defense (IgA) and cell proliferation (Ki-67) of female aged rats.

Blood plasma therapy, a new treatment method to eliminate the damage and deterioration caused by aging in many organ systems, has attracted increasing attention. The digestive tract, which cooperates with many different systems, has strong effects on our health. In the present study, the effects of plasma therapy on the ileum of elderly rats were investigated.

Promoting longevity in aged liver through NLRP3 inflammasome inhibition using tauroursodeoxycholic acid (TUDCA) and SCD probiotics.

This investigation explores the combined influence of SCD Probiotics and tauroursodeoxycholic acid (TUDCA) on liver health in elderly male Sprague-Dawley rats. Through the administration of intravenous TUDCA (300 mg/kg) and oral SCD Probiotics (3 mL at 1 × 10^8 CFU) daily for one week, this study evaluates the biomolecular composition, histopathological alterations, and inflammasome activity in the liver. Analytical methods encompassed ATR-FTIR spectroscopy integrated with machine learning for the assessment of biomolecular structures, RT-qPCR for quantifying inflammasome markers (NLRP3, ASC, Caspase-1, IL18, IL1β), and histological examinations to assess liver pathology.

Supplementing probiotics during intermittent fasting proves more effective in restoring ileum and colon tissues in aged rats.

This study aimed to explore the impact of SCD Probiotics supplementation on biomolecule profiles and histopathology of ileum and colon tissues during a 30-day intermittent fasting (IF) program. Male Sprague-Dawley rats, aged 24 months, underwent 18-h daily fasting and received 3 mL (1 × 108 CFU) of SCD Probiotics. The differences in biomolecule profiles were determined using FTIR Spectroscopy and two machine learning techniques, Linear Discriminant Analysis (LDA) and Support Vector Machine (SVM), which showed significant differences with high accuracy rates.

SCD Probiotics mitigate cafeteria diet-induced liver damage in Wistar rats during development.

Background And Aim: The liver plays a critical role in metabolic homeostasis, and its health is often compromised by poor dietary habits. This study aimed to investigate the therapeutic potential of SCD Probiotics in mitigating adverse liver effects induced by a cafeteria diet in male Wistar rats during their developmental period.

Methods: Four groups of seven male Wistar rats each were subjected to different dietary regimens from day 21 (weaning) to day 56.

Reduced liver damage and fibrosis with combined SCD Probiotics and intermittent fasting in aged rat.

This study aimed to examine the impact of SCD Probiotics supplementation on liver biomolecule content and histological changes during a 30-day intermittent fasting (IF) program in 24-month-old male Sprague-Dawley rats. Rats underwent 18-h daily fasting and received 1 × 10 CFU of SCD Probiotics daily. Liver tissue biomolecules were analysed using FTIR Spectroscopy, LDA, and SVM techniques, while histopathological evaluations used Haematoxylin and eosin and Masson trichrome-stained tissues.

The rejuvenating influence of young plasma on aged intestine.

This study aims to investigate the effects of plasma exchange on the biomolecular profiles and histology of ileum and colon tissues in young and aged Sprague-Dawley male rats. Fourier transform infrared (FTIR) spectroscopy, linear discriminant analysis and support vector machine (SVM) techniques were employed to analyse the lipid, protein, and nucleic acid indices in young and aged rats. Following the application of young plasma, aged rats demonstrated biomolecular profiles similar to those of their younger counterparts.

Age-related differences in response to plasma exchange in male rat liver tissues: insights from histopathological and machine-learning assisted spectrochemical analyses.

This study aimed to examine the biological effects of blood plasma exchange in liver tissues of aged and young rats using machine learning methods and spectrochemical and histopathological approaches. Linear Discriminant Analysis (LDA) and Support Vector Machine (SVM) were the machine learning algorithms employed. Young plasma was given to old male rats (24 months), while old plasma was given to young male rats (5 weeks) for thirty days.

Role of age-related plasma in the diversity of gut bacteria.

Recent studies have demonstrated the efficacy of young blood plasma factors in reversing aging-related deformities. However, the impact of plasma exchange between young and old individuals on gut microbiota remains understudied. To investigate this, we evaluated the effects of plasma exchange between 5-week-old and 24-month-old rats on gut microbiota composition.

Young plasma transfer recovers decreased sperm counts and restores epigenetics in aged testis.

Background And Aim: Aging is one of the causes of male infertility, and abnormal global DNA methylation and imprinting defects have been characterized in testis during biological aging. One of the important emerging approaches aims to take advantage of the healing properties of young blood plasma to limit the progression of aging in various organs in the body. We aimed to show whether blood plasma transfer has an effect on DNA methylation and spermatogenetic cell development.

Infrared spectrochemical findings on intermittent fasting-associated gross molecular modifications in rat myocardium.

Cardiovascular diseases are among the primary life-threatening conditions affecting human society. Intermittent fasting is shown to be functional in the prevention of cardiovascular diseases, however, the information on fasting-associated modifications in myocardial biomolecules is limited. This study aimed to determine the impact of 18-h intermittent fasting administered for five weeks on 12 months-old rats using supervised linear discriminant analysis and support vector machine algorithms constructed on spectrochemical data obtained from myocardial tissues.

Intermittent fasting supports the balance of the gut microbiota composition.

There is a growing body of detailed research demonstrating that intermittent fasting is essentially a cleansing activity in terms of health. Especially since its applications that exceed 16 h trigger autophagy, it continues its effect on all tissue and organ systems after the regeneration movement that starts at the cellular level. Similarly, it continues to be better understood with each passing day that the gut microbiota (GM) has many positive effects on all tissue and organ systems.

The effect of young blood plasma administration on gut microbiota in middle-aged rats.

Numerous in-depth studies continue to reveal the many benefits of gut microbiota and young blood plasma administration. Dysbiosis, which occurs in the intestinal microbiota, especially in the aging process, is associated with many metabolic and cognitive disorders. Therefore, many studies aim to reverse the dysbiosis that occurs.

Intermittent fasting-induced biomolecular modifications in rat tissues detected by ATR-FTIR spectroscopy and machine learning algorithms.

This study aimed to reveal the intermittent fasting-induced alterations in biomolecules of the liver, ileum, and colon tissues of rats using Support Vector Machine (SVM) and Linear Discriminant Analysis (LDA) algorithms developed on infrared spectrochemical data. LDA prediction accuracies were generally calculated in the range of 95-100%, while training and validation accuracies of SVM were in the range of 91-100% and 83-91%, respectively. The quantitative measurements of spectral bands at the CH (lipids), Amide (proteins), and PO antisymmetric (nucleic acids) stretching regions were performed to monitor modulated metabolic processes.

The effects of repeated antibiotic administration to juvenile BALB/c mice on the microbiota status and animal behavior at the adult age.

Recent studies carried on germ -free (GF) animal models suggest that the gut microbiota (GM) may play a role in the regulation of anxiety, mood, and cognitive abilities such as memory and learning processes. Consistently, any treatment disturbing the gut microbiota, including the overuse of antibiotics, may influence the brain functions and impact behavior. In the present study, to address this issue, two wide-spectrum antibiotics (ampicillin and cefoperazone, 1 g/l) were repeatedly applied throughout a 6-week period to initially 21-day-old male BALB/c mice.
