Esophageal chondromatous hamartomas are very rare tumors, characterized by proliferating hyaline cartilage cells. We described the case of a 64-year-old woman, with a progressive foreign body sensation in the laryngopharynx caused by an intraluminal pedicled mass. Transcervical esophagectomy was performed and intraoperative biopsy revealed the mass was a cervical esophageal chondromatous hamartoma. The patient's postoperative course was uneventful and she recovered well. A review of the literature was conducted, and the symptoms, locations, histopathology findings, treatment methods and follow up results of esophageal hamartoma cases were summarized...

BACKGROUND: Age-related chronic diseases are prevalent in HIV-infected persons in the antiretroviral therapy (ART) era. Bone mineral density (BMD) loss and emphysema have separately been shown to occur at a younger age and with lesser risk exposure in HIV-infected compared to HIV-uninfected individuals. In non-HIV infected smokers, emphysema has been shown to independently predict low BMD. We hypothesized that emphysema would independently associate with thoracic vertebral bone attenuation, a surrogate for bone mineral density, in HIV-infected individuals...

The indigenous people of the Tibetan Plateau have been the subject of much recent interest because of their unique genetic adaptations to high altitude. Recent studies have demonstrated that the Tibetan EPAS1 haplotype is involved in high altitude-adaptation and originated in an archaic Denisovan-related population. We sequenced the whole-genomes of 27 Tibetans and conducted analyses to infer a detailed history of demography and natural selection of this population. We detected evidence of population structure between the ancestral Han and Tibetan subpopulations as early as 44 to 58 thousand years ago, but with high rates of gene flow until approximately 9 thousand years ago...

Li-S batteries have been extensively studied using rigid carbon as the host for sulfur encapsulation, but improving the properties with a reduced electrolyte amount remains a significant challenge. This is critical for achieving high energy density. Here, we developed a soft PEO10LiTFSI polymer swellable gel as a nanoscale reservoir to trap the polysulfides under lean electrolyte conditions. The PEO10LiTFSI gel immobilizes the electrolyte and confines polysulfides within the ion conducting phase. The Li-S cell with a much lower electrolyte to sulfur ratio (E/S) of 4 gE/gS (3...

The synthesis of Co3O4 nanomaterials with diverse morphologies were usually synthesized in liquid phase accompanied by the template or surfactant, even harsh conditions, which further restricted their practical application. Herein, we reported an extremely simple and practical solid-state chemical method to synthesize Co3O4-octahedrons, -plates and -rods. Among these, the shape control of Co3O4-octahedrons and Co3O4-plates involve the variation of the amount of reactant, and the formation of Co3O4-rods with {110} facet can be achieved by replacing the reactant...

A visible-light-induced and iron-catalyzed methylation of arylacrylamides by dimethyl sulphoxide (DMSO) is achieved, leading to 3-ethyl-3-methyl indolin-2-ones in high yields. This reaction tolerates a series of functional groups, such as methoxy, trifluoromethyl, cyano, nitro, acetyl and ethyloxy carbonyl groups. The visible-light promoted radical methylation and arylation of the alkenyl group are involved in this reaction.
