OBJECTIVE: Due to the aging of populations, the prevalence of hearing loss and osteoporosis is increasing. Previous studies have found an association between these conditions. Nevertheless, the pathophysiologic pathway of such an association has not yet been established. The present study aimed at evaluating the association, if any, of hearing loss with osteoporosis in an older unselected population, and whether this association varied according to inflammatory status. PATIENTS AND METHODS:   We assessed the association of osteoporosis with a self-reported hearing loss in all 310 subjects aged 75+ living in Tuscania (Italy), without exclusion criteria...

OBJECTIVE: Liver cysts are divided into congenital and acquired. Congenital cystic lesions include polycystic liver disease, simple cysts, duct related and ciliated hepatic foregut cysts. Acquired cystic lesions are divided into infectious and non-infectious. The infectious cysts are the hydatid cyst, the amoebic abscess, and the pyogenic abscess, whereas the non-infectious cysts are neoplastic cysts and false cysts. While modern medicine provides a lot of minimally invasive therapeutic modalities, there has emerged a pressing need for understanding the various types of liver cysts, the possible minimal therapeutic options along with their indications and complications...

OBJECTIVE: Emerging evidence suggests aberrant microRNAs (miRNAs) expression is involved in cancer development through multiple. Although miR338 has shown to have tumor suppression ability and anti-migration effects in some cancers, its regulatory role and molecular mechanism in the development of gastric cancer cells yet remains little known. This work aims to investigate miR-338 in regulating Wnt/β-catenin pathway in epithelial-mesenchymal transition (EMT) in gastric cancers. MATERIALS AND METHODS: Human gastric cancer cells were transfected with either miR-338 mimic or erythropoietin-producing hepatocellular (Eph)A2-targeting siRNA...

cFLIP is a key regulator of the anti‑apoptotic mechanism and its association with FAS‑mediated apoptosis has been widely studied and well documented. However, the equipoise between its two isoforms i.e. the long isoform cFLIP(L) and the short isoform cFLIP(S) during FAS‑mediated apoptosis remains to be revealed. Therefore, the present study aimed to investigate the regulatory effect of these isoforms on FasL‑mediated apoptosis in renal carcinoma. Our results revealed that FasL treatment to Caki cells induced the expression of cFLIP(S) and downregulated the expression of cFLIP(L) in a concentration‑ and time‑dependent manner...

Daily vs. weekly dosing with EGFR inhibitors (gefitinib and lapatinib) and an AKT inhibitor (MK2206) were compared in two rodent breast cancer models. Female Sprague-Dawley rats were administered methylnitrosourea (MNU) at 50 days of age, and gefitinib (daily/weekly dosing at 10/70 mg/kg BW) or lapatinib (daily/weekly dosing at 75/525 mg/kg BW) were administered by gavage beginning 5 days after MNU. For the prevention studies, weekly or daily dosing with gefitinib or lapatinib reduced cancer multiplicity >75%, and all treatments reduced tumor weights by >90%...

Triple-negative breast cancer (TNBC) and malignant melanoma are highly aggressive cancers that widely express the cell surface chondroitin sulfate proteoglycan 4 (CSPG4/NG2). CSPG4 plays an important role in tumor cell growth and survival and promotes chemo- and radiotherapy resistance, suggesting that CSPG4 is an attractive target in cancer therapy. In the present work, we applied the drug delivery technology photochemical internalization (PCI) in combination with the novel CSPG4-targeting immunotoxin 225...

Localized separation of strands of duplex DNA is a necessary step in many DNA-dependent processes, including transcription and replication. Little is known about how these strand separations occur. The strand-separated E.coli RNA polymerase-promoter open-complex structure showed four bases of the non-template strand, the master base -11A, -7, -6 and +2, in a flipped state and inserted into protein pockets. To explore whether any property of these bases in the duplex state pre-disposes them to flipping, NMR studies were performed on a wild-type promoter in the duplex state...

The biological properties of circulating tumor cells (CTCs), and their dynamics during neoadjuvant chemotherapy are important, both for disease progression prediction and therapeutic target determination, with the aim of preventing disease progression. The aim of our study was to estimate of different CTC subsets in breast cancer during the NACT (neoadjuvant chemotherapy). The prospective study includes 27 patients with invasive breast cancer, T2-4N0-3M0, aged 32 to 60 years. Venous heparinized blood samples, taken before and after biopsy, after each courses of chemotherapy (on days 3-7), and before surgical intervention, served as the material for this study...

Diabetic retinopathy is a common complication of diabetes and remains the leading cause of blindness among the working-age population. For decades, diabetic retinopathy was considered only a microvascular complication, but the retinal microvasculature is intimately associated with and governed by neurons and glia, which are affected even prior to clinically detectable vascular lesions. While progress has been made to improve the vascular alterations, there is still no treatment to counteract the early neuro-glial perturbations in diabetic retinopathy...

The structural, electronic, and magnetic properties of two-dimensional (2D) GaS are investigated using density functional theory (DFT). 
 After confirming that the pristine 2D GaS is a non-magnetic, indirect band gap semiconductor, we consider N and F as substitutional dopant's or adsorbed atoms. Except for N substituting for Ga (N$_{\rm Ga}$), all considered cases are found to possess a magnetic moment. Fluorine, both in its atomic and molecular form, undergoes a highly exothermic reaction with GaS...

Vibrio coralliilyticus is a known pathogen to corals and larvae of bivalves. Its identification is made based on phenotypic and genotypic characters of isolated strains. To evaluate the efficiency of the phenotypic identification, 21 strains identified as V. coralliilyticus using a widely used dichotomous key were analyzed by qualitative PCR and sequencing of the 16S rDNA region. The results obtained by the behavioral test, amino acids usage, allow us to distinguish 3 A/L/O profiles: (1) A+/L-/O+; (2) A+/L+/O+; and (3) A-/L+/O+...
