Diabetic Nephropathy (DN) is one of the main complications associated with diabetes mellitus. Persistently elevated blood glucose level drives histopathological changes in renal tissues that hinder normal kidney functions. In the current study, crocin; the main bioactive constituent of Crocus sativus was investigated as a reno-protective agent against DN by virtue of its numerous pharmacological activities. Diabetes was induced in male Sprague-Dawely rats through intravenous injection of streptozocin (STZ) (50 mg/kg), DN was confirmed eight weeks post diabetes induction...

Tumours arising from the parapharyngeal space (PPS) represent less than 1% of all head and neck tumours. Salivary gland tumours account for 40-50% of PPS lesions and are located in the pre-styloid parapharyngeal space. Pleomorphic adenomas represent 80-90% of salivary tumours in the PPS. Recently, transoral robotic surgery (TORS) has become common in head and neck surgery as a minimally invasive procedure. Four cases of benign PPS tumour treated with TORS are presented here. Preoperative diagnosis was conducted by fine needle aspiration biopsy and magnetic resonance imaging, and the results were used to plan the correct surgical approach...

Actinobacillus pleuropneumoniae (APP) causes serious economic losses in the swine industry, and is the etiologic agent of porcine pleuropneumonia. In this study we have engineered a trivalent Apx fusion protein enclosed in outer membrane vesicles (Apxr-OMV) and studied its immunoprotective efficacy against APP serotypes 1 and 7 challenge in mice. The results showed that the IgG levels in the Apxr-OMVs immune group were significantly higher than those of the negative control (P < 0.05). Up-regulation of both Th1 (IFN-γ, IL-2) and Th2 (IL-4) cytokines were detected in splenocytes of Apxr-OMVs immune group...

BACKGROUND: Actinic keratosis (AK) is a photo-induced skin lesion. It has been considered by several authors as in situ squamous cell carcinoma (SCC), that can evolve to invasive SCC (iSCC). Given the malignant potential and because it's impossible predict which AK will evolve in iSCC, it's necessary to treat each lesion. Multiple therapeutic approaches have been described to treat AKs. In addition to the topical drugs, photodynamic therapy (PDT) has become an established therapeutic modality for grade I and II of AKs of face and scalp...

Kaposi's sarcoma-associated herpesvirus (KSHV) is the etiologic agent of Kaposi's sarcoma (KS). It is endemic in a number of sub-Saharan African countries with infection rate of >50%. The high prevalence of HIV-1 coupled with late presentation of advanced cancer staging make KS the leading cancer in the region with poor prognosis and high mortality. Disease markers and cellular functions associated with KS tumorigenesis remain ill-defined. Several studies have attempted to investigate changes of the gene profile with in vitro infection of monoculture models, which are not likely to reflect the cellular complexity of the in vivo lesion environment...

Meniscal injuries and meniscal loss are associated with changes in knee kinematics and loading, ultimately leading to poor functional outcomes and increased risk of progression to osteoarthritis. Biomechanical studies have shown restored knee function, and clinical studies have reported improved outcomes and decreased risk of osteoarthritis after meniscal repair. This has led orthopaedic surgeons to try and save the meniscus by repair whenever possible, as shown by increasing incidence of meniscal repair surgeries...
