To evaluate the effectiveness of ultrasound (US) and computed tomography (CT) in diagnosing salivary gland neoplasms, 99 patients (benign tumor--72; salivary cyst--4 and malignant tumor--23) were examined. Also, 84 ultrasound-guided fine-needle aspiration biopsies were performed. Both US and CT showed high diagnostic potential in dealing with bulky lesions of the glands. Although sensitivity was 55.6 and 66.7, specificity--98.2 and 98.7 and accuracy of differential diagnosis between benign and malignant lesions--87.6 and 91.8%, respectively, differential diagnosis of benign and malignant tumors on the basis of US and CT evidence alone is not possible.

Background: Primary Sjögren Syndrome (pSS) is an autoimmune disease that usually affects salivary glands. Research about the impact of oral health in quality of life of patients with pSS is scarce.
Objectives: to describe the characteristics of oral involvement in patients with pSS; To assess quality of life related to oral health (QOL-OH); to determine association between QOL-OH and saliva production, disease activity, and damage.

Dopamine plays multifaceted roles in the physiology of insects and ticks, acting as a key neurotransmitter and modulator of various biological processes. In ticks, it plays a particularly important role in regulating salivary gland function, which is essential for successful tick feeding on hosts. Salivary secretion in ticks is orchestrated by the collection of saliva in the acinar lumen mediated by the dopamine receptor (D1) and the expulsion of collected saliva into the salivary duct mediated by the invertebrate specific D1-like dopamine receptor (InvD1L).

Introduction: Pleomorphic adenoma, the most common benign salivary gland tumor, typically occurs in the parotid region but can also arise in minor salivary glands. Its occurrence in the lateral tongue is infrequent, making this case the first reported from Ethiopia and the second in English literature.
Case Presentation: We present an 11-year-old girl who underwent an excisional biopsy for a tongue swelling lasting 2 years.
Co-Infection of Mosquitoes with Rift Valley Fever Phlebovirus Strains Results in Efficient Viral Reassortment.

Rift Valley fever phlebovirus (RVFV) is a zoonotic mosquito-borne pathogen endemic to sub-Saharan Africa and the Arabian Peninsula which causes Rift Valley fever in ruminant livestock and humans. Co-infection with divergent viral strains can produce reassortment among the L, S, and M segments of the RVFV genome. Reassortment events can produce novel genotypes with altered virulence, transmission dynamics, and/or mosquito host range.

The dengue virus (DENV) is primarily transmitted by . Investigating genes associated with mosquito susceptibility to DENV2 offers a theoretical foundation for targeted interventions to regulate or block viral replication and transmission within mosquitoes. Based on the transcriptomic analyses of the midgut and salivary glands from infected with DENV2, alongside analyses of Aag2 cell infections, 24 genes potentially related to the regulation of infection with DENV2 were selected.
