Summary: Phospholipase and yolk agglutinase in dairy goat seminal plasma have toxic and side effects on sperm. By replacing dairy goat seminal plasma with bovine seminal plasma, the freezing quality of Guanzhong dairy goat semen, sperm motility, plasma membrane functionality, acrosome integrity rate, oxidation index, and fertilization ability can be significantly improved.

Summary: This study investigates the effects of seminal plasma (SP) identity and protein composition on human sperm function. The results show that SP identity and its protein composition play a role in sperm swimming velocity, viability, and hyperactivation. The interaction between sperm and SP donor also affects sperm performance. Additionally, specific SP proteins, such as DPP4 and NEP, are positively associated with sperm swimming velocity and hyperactivation.

Summary: Mammalian seminal plasma contains various bioactive components that play important roles in fertilization. The seminal plasma protein PDC-109 not only affects sperm function but also exhibits antimicrobial and antiviral activity, potentially limiting the sexual transmission of infectious diseases. Recent research has found that PDC-109 inhibits the membrane fusion activity of influenza virus particles and significantly impairs viral infections, including SARS-CoV-2. These findings suggest that PDC-109 has broad antiviral activity against multiple virus species and families.

Summary: The aim of this study was to investigate the effects of hesperidin on hyperthyroidism in rats, with a focus on its immunomodulatory and antioxidant properties. The findings showed that hesperidin significantly improved the hyperthyroidism-induced changes in hormone levels, inflammation, and oxidative stress. Additionally, hesperidin displayed nephro-hepatoprotective and anti-atherogenic potential. These results suggest that hesperidin has anti-hyperthyroidism, immunoinflammatory regulatory, and antioxidant activities.

Summary: Through analyzing the semen production records of core breeding farms and bull stations for the past 10 years, it was found that semen collected for the first time from 5-year-old bulls had the best quality. Despite the collection of bull semen under the mentioned conditions, some bulls still produced low-quality sperm due to individual differences. Interestingly, seminal plasma from normal semen was able to improve the motility of low-quality semen. The differences in miRNA and metabolite profiles between normal and low-quality seminal plasma provided potential biomarkers for identifying high semen quality.

Summary: Non-thermal plasma (NTP) is a promising technique in agriculture that can improve plant material by modulating gene expression related to seed germination, plant immune response, pathogen resistance, and growth. This review focuses on the application of NTP on seeds, which leads to both external and internal changes, improving seed coat hydrophilicity and interfering with cellular processes. The use of plasma aims to reduce the usage of fertilizers and pesticides, thereby minimizing negative impact on the environment and production costs.

Summary: This study found that the presence of seminal plasma contributes to maintaining acrosomal integrity and reducing F-actin cytoskeleton remodelling in bovine sperm. Cooling stage induced the highest F-actin remodelling, while freezing/thawing stage caused the most damage to sperm membranes and mitochondrial potential.

Summary: This study found that the antioxidant components of donkey seminal plasma (SP) are related to sperm cryotolerance. The activity levels of enzymatic and non-enzymatic antioxidants are positively correlated with post-thaw sperm motility and plasma membrane integrity, and negatively correlated with intracellular reactive oxygen species (ROS) levels. SP-OSI is negatively correlated with sperm quality parameters and positively correlated with intracellular ROS levels. Therefore, PON1, SOD, CUPRAC, FRAP, TEAC, and SP-OSI could be used as markers of sperm cryotolerance.

Summary: The study showed that implantation rates were lower in female mice treated with seminal plasma from reproductively older males compared to those treated with seminal plasma from younger males. RNA-sequencing analysis revealed altered levels of dendritic cell-related cytokines and chemokines in the uteri of the former group. In vivo and in vitro experiments demonstrated a weaker inhibitory effect of aged seminal plasma on dendritic cell maturation.

Summary: Seminal plasma serves as a transport medium for sperm and facilitates communication between male and female reproductive tissues. It plays a vital role in preparing the female reproductive tract for optimal pregnancy, enhancing debris clearance and supporting embryo growth. It also regulates the functions of female reproductive organs and promotes effective embryo implantation and pregnancy.

Summary: This review summarizes preclinical studies on the anti-inflammatory activity of steroidal saponins through the modulation of inflammatory cytokines. The results show that steroidal saponins and sapogenins have anti-inflammatory, antinociceptive, and antioxidant effects, and they mainly modulate inflammatory cytokines through the Nf-Kappa B, TLR4, and MAPKs pathways.

Summary: African swine fever (ASF) has been spreading rapidly and poses a threat to the global pig industry. Hunters in Latvia have been involved in controlling ASF and passive disease surveillance since 2014. The study evaluated hunters' acceptability of ASF control measures and explored new ways to increase their motivation to report dead wild boar. Relationships between hunters, the Food and Veterinary Service (FVS), and State Forest Service (SFS) were found to be satisfactory, with hunters supporting measures to reduce infection pressure in forests.

Summary: The study showed that the monitoring system in Estonia was unable to detect virus circulation and there was no significant accumulation of serologically positive wild boar in temporal connection to the re-emergence of ASFV. Additionally, with the decreasing wild boar population density and ongoing surveillance activities, the circulation of ASFV at a low prevalence was deemed unlikely.

Summary: This study investigated potential risk factors associated with African swine fever (ASF) outbreaks in pig farms in Lithuania in 2019. The study found that veterinary inspections significantly reduced the risk of ASF occurrence in a pig farm, while certain activities increased the odds of an outbreak. These findings are important for improving ASF control and prevention.

Summary: This study evaluated surveillance data on African swine fever (ASF) in Lithuania, Latvia, and Estonia, and found a decreasing trend in virus prevalence in wild boar, a slight increase in seroprevalence, and a significant decrease in wild boar population density. The results suggest that controlling ASF has become more difficult and calls for a reevaluation of current control strategies.

Summary: African swine fever (ASF) first emerged in Latvia in 2014 and then in Saxony, Germany in 2020. The virus was most likely introduced by infected wild boar from neighboring countries. The control measures for ASF differed between the two regions due to the lack of a developed strategy in Latvia. Comparing the ASF epidemic in Saxony and Latvia, it was found that Saxony had a lower prevalence of ASF virus-positive wild boar, indicating better preparation and control strategies.
