OBJECTIVE We sought to investigate the role of Streptococcus pneumoniae (SP) nasopharyngeal (NP) colonization after successful antibiotic treatment (Rx) of acute otitis media (AOM) in recurrent AOM (RAOM). PATIENTS AND METHODS NP cultures were obtained from 494 (93%) of 530 patients at the end of antibiotic treatment (EOT). RESULTS At enrollment, middle ear fluid (MEF) cultures in 418 (79%)...

BACKGROUND Internet access via mobile phones and computers facilitates interaction and potential health communication among individuals through social networking. Many South African adolescents own mobile phones and can access social networks via apps. OBJECTIVE We investigated sociodemographic factors and HIV risk behaviors of adolescent social networking users in Soweto, South Africa. MET...

Dermatophytosis is caused by a dermatophyte fungus that affects the stratum corneum and keratinized tissue. Dermatophyte fungus has been reported worldwide as the causative agent of dermatophytosis, but the etio-epidemiological aspects of these mycoses in the state of Pará remain unknown. The purpose of this study was to describe the etio-epidemiological profile of dermatophytosis diagnosed in ...

The RNA-binding protein (RBP) nucleolin promotes the expression of several proliferative proteins. Nucleolin levels are high in cancer cells, but the mechanisms that control nucleolin expression are unknown. Here, we show that nucleolin abundance is controlled posttranscriptionally via factors that associate with its 3' untranslated region (3'UTR). The RBP HuR was found to interact with the nuc...

BACKGROUNDS Portal vein embolization (PVE) has been widely applied before extended hepatectomy; however, its clinical utility for patients with biliary cancer has not been fully addressed. METHODS Between 1991 and 2010, 494 patients with cholangiocarcinoma (n = 353) or gallbladder cancer (n = 141) underwent PVE before extended hepatectomy. PVE was performed by a transhepatic ipsilateral appro...

Several intracellular pathogens arrest the phagosome maturation in the host cells to avoid transport to lysosomes. In contrast, the Leishmania containing parasitophorous vacuole (PV) is shown to recruit lysosomal markers and thus Leishmania is postulated to be residing in the phagolysosomes in macrophages. Here, we report that Leishmania donovani specifically upregulates the expression of Rab5a...

Gummy stem blight is a major foliar disease of muskmelon (Cucumis melo L.). In this study, morphological characteristics and rDNA internal transcribed spacer (ITS) sequences were analyzed to identify the causal organism of this disease. Morphological examination of the Jeonbuk isolate revealed that the percentage of monoseptal conidia ranged from 0% to 10%, and the average length × width of the...

A high-throughput computational dataset of halide perovskite alloys is generated from 494 unique compositions, using multiple DFT functionals. The further applied to screen promising perovskites with high stability, suitable band gap and excellent PV efficiency.
