Objective: This study aims to investigate whether alterations in sperm DNA fragmentation rates are more frequent when Krüger strict morphology is ≥4% (normal).
Methods: The retrospective study included 132 participants from March 2020 to November 2021. Participants were divided into two groups based on the inclusion criteria: normal and abnormal Krüger strict morphology, with a mean age of 40 years. Seminal analyses were conducted following the guidelines outlined in the 6th edition of the Manual for Examination and Processing of Human Semen (2021). The sperm chromatin dispersion test was used.
Results: The results did not reveal a statistically significant difference between Krüger strict morphology and Sperm DNA Fragmentation Index correlation (p<0.05) between the normal and abnormal morphology groups (p<0.05) and in Seminal Parameters. Sperm concentration is lower when Krüger strict morphology is < 4% (abnormal) (p=0.007).
Conclusions: In conclusion, abnormal Krüger strict morphology does not have a higher predisposition to increased sperm DNA fragmentation.

While numerous studies have established correlations between parasite load and negative effects on their hosts, establishing causality is more challenging because parasites can directly compromise host condition and survival or simply opportunistically thrive on an already weakened host. Here, we evaluated whether Ixodes uriae, a widespread seabird tick, can cause a decrease in growth parameters (body mass, bill length and growth rates) and survival of chicks of a colonially seabird, the black-browed albatross (Thalassarche melanophris) breeding on New Island (West Falkland). To investigate this, we daily removed the ticks from 28 randomly selected chicks during their first 14 days of life (treated chicks) and compared their growth and survival with 49 chicks of a control group.

The Brief Inventory of Thriving (BIT) provides a holistic measure of well-being, but has only been validated for adults, and does not have a Hindi version. The present study investigated the unidimensional structure, internal consistency, convergent/discriminant, and criterion validity of both the original English version of the BIT (BIT-E) and its Hindi-translated version (BIT-H) among adolescents in India. Further, we tested measurement invariance across these two language versions, gender, and academic disciplines.

For over a century African swine fever (ASF) has been causing outbreaks leading to devastating losses for the swine industry. The current pandemic of ASF has shown no signs of stopping and continues to spread causing outbreaks in additional countries. Currently control relies mostly on culling infected farms, and strict biosecurity procedures.

Background: Hyperglycemia is a condition in which blood sugar levels increase excessively due to a variety of factors, one of which is the body's inability to regulate insulin properly. Diabetes closely relates to this condition, which significantly contributes to premature death and disability. Long-term diabetes treatment accompanied by a strict diet provides real results in controlling blood glucose levels but can cause side effects.

Background: Tuina is an effective treatment for the decrease of skeletal muscle atrophy after peripheral nerve injury. However, the underlying mechanism of action remains unclear. This study aimed to explore the underlying mechanisms of tuina in rats with sciatic nerve injury (SNI).
