Summary: Greyscale and Colour Doppler ultrasound are main imaging modalities for scrotal trauma, with Contrast-enhanced ultrasound and elastography as advanced techniques for equivocal cases. ESUR-SPIWG provides guidance for the utilization of multiparametric ultrasound in scrotal trauma evaluation.

Summary: Bulls' subfertility significantly affects cattle enterprises' production efficiency and profitability. This study aimed to develop a comprehensive index of indicative fertility in bulls by incorporating testicular ultrasonography and hormonal status in the bull breeding soundness evaluation (BBSE). Bulls with homogeneous testicular parenchyma exhibited a higher percentage of motile sperm after thawing compared to bulls with heterogeneous parenchyma. Furthermore, in bulls with homogeneous parenchyma, the percentage of motile sperm, progressively motile sperm, and motility yield were positively correlated with hair DHEA-S concentration. Therefore, the integration of testicular ultrasonography and DHEA-S status in the BBSE can provide a more comprehensive assessment of bulls' potential fertility.

Summary: The tetrel bond between 1,2-benzisothiazol-3-one-2-TF3-1,1-dioxide (T = C, Si) and pyridine-1-oxide (PO) and its derivatives (PO-X, X = H, NO2, CN, F, CH3, OH, OCH3, NH2, and Li) was investigated using quantum chemical methods. The Si-O tetrel bond is strong, with interaction energies reaching a maximum of nearly 70 kcal/mol, while the C-O tetrel bond is weaker, with interaction energies between 2.0 and 2.6 kcal/mol. The presence of an electron-withdrawing substituent weakens the tetrel bond, while an electron-donating group strengthens it. The SiF3 group transfers approximately halfway between the acid's nitrogen and the base's oxygen without the assistance of cooperative effects from a third entity.

Summary: Pathological factors such as fibrosis stage and histological grade can influence the contrast-enhanced ultrasonography (CEUS) Liver Imaging Reporting and Data System (LI-RADS) classification in patients at high risk of hepatocellular carcinoma. Hepatic fibrosis stage may affect arterial phase hyperenhancement (APHE) but does not impact the CEUS LI-RADS classification, while the histological grade of HCC can influence LR-5 and LR-TIV categories.

Summary: In this study, lectin histochemistry was used to compare the cellular localization of sugar residues in bull and donkey testes. While the basic testicular structure was similar in both species, different lectin localization patterns were observed in cellular components. Statistical analysis did not show a significant association between labeling intensity and different variables, but a stronger response was observed in donkey testes compared to bull testes.

Summary: Unlike younger patients, seminoma is not common in patients with primary testicular tumors over the age of 50. The diagnostic value of conventional ultrasonography and contrast-enhanced ultrasonography (CEUS) in these patients was compared. The CEUS method showed higher accuracy in distinguishing between germ cell tumors and non-germ cell tumors.

Summary: Lead (Pb) is widely present in soil and poses a serious threat to agricultural soil and food crops. This study established animal and cell models to investigate the relationship between Pb-induced testicular injury and pyroptosis-mediated fibrosis. The results showed that Pb caused oxidative stress and increased the expression of inflammation, pyroptosis, and fibrosis-related proteins in the testis. In vitro experiments also demonstrated that Pb induced cell damage and elevated reactive oxygen species levels in TM4 Sertoli cells.

Summary: This study explored the value and mechanism of ultrasound-targeted microbubble destruction (UTMD)-mediated Galectin-3 (Gal-3) short hairpin RNA (shRNA) transfection in anti-myocardial fibrosis. The results showed that Gal-3 shRNA/CMBs + US improved left ventricular ejection fraction (LVEF) and reduced myocardial fibrosis area, collagen expression, and production. In conclusion, UTMD-mediated Gal-3 shRNA transfection effectively silenced Gal-3 expression, alleviated myocardial fibrosis, and protected cardiac ejection function.

Summary: This study explores the association between lncRNAs and testicular development and spermatogenesis in Holstein bulls through transcriptome analysis. A large number of differentially expressed lncRNAs and mRNAs were identified, and their relationships were analyzed. Further investigation revealed that certain lncRNAs and mRNAs are involved in cell cycle regulation and spermatogenesis. This study reveals the regulatory mechanisms of lncRNAs in testicular development and spermatogenesis.

Summary: This study explored the use of strain elastography in the evaluation of testicular focal lesions and found that testes with abnormal spermatogenesis were stiffer compared to normal testes. The study suggests that strain elastography can be used to support the andrological examination.

Summary: This study assessed the feasibility of shear-wave elastography (SWE) in evaluating testicular involvement of hematologic malignancies in children and young adults. The results showed that increased testicular stiffness on SWE suggests the possibility of testicular involvement, with stiffness ratio being an indicator of the extent of involvement. Additionally, follow-up SWE demonstrated a decrease in stiffness after treatment in one patient.

Summary: This study conducted a large-scale survey of gastrointestinal nematode (GIN) in beef herds across western Canada. The results showed regional heterogeneity of GIN species, with Ostertagia ostertagi and Cooperia on cophora being the predominant species in Alberta and Saskatchewan, while Cooperia punctata was the predominant species in Manitoba. This unexpected predominance of C. punctata at a northerly latitude could be due to range expansion associated with changes in climate, anthelmintic use, management, and/or animal movement.
