J-shaped association between serum albumin levels and long-term mortality of cardiovascular disease: Experience in National Health and Nutrition Examination Survey (2011-2014).

Background: Cardiovascular disease (CVD) is a constellation of heart, brain, and peripheral vascular diseases with common soil hypothesis of etiology, and its subtypes have been well-established in terms of the albumin-mortality association. However, the association between albumin and the mortality of CVD as a whole remains poorly understood, especially the non-linear association. We aimed to investigate the association of albumin levels with long-term mortality of CVD as a whole.

Cyclophilin D is an important component of the mitochondrial permeability transition pore.

Clinical and Genetic Analysis of a Family With Sitosterolemia Caused by a Novel ATP-Binding Cassette Subfamily G Member 5 Compound Heterozygous Mutation.

Sitosterolemia (OMIM ##210250), also known as phytosterolemia, is a rare autosomal recessive disorder caused by mutations in the ATP-binding cassette subfamily G member 5 () or member 8 () genes. This leads to abnormal functions of the transporter sterolin-1 protein encoded by G5 and sterolin-2 protein encoded by G8, respectively, which can hinder the formation of stable / heterodimers, decreasing its ability to transport sterols. As a result, phytosterols in tissue or plasma are significantly increased, leading to early onset atherosclerosis-related diseases and xanthelasma of tendons and skin.

Chondroitin sulfate proteoglycan represses neural stem/progenitor cells migration via PTPσ/α-actinin4 signaling pathway.

Neural stem/progenitor cells (NSPCs) are a promising candidate for the cell-replacement therapy after central nervous system (CNS) injury. However, the short of sufficient NSPCs migration and integration into the lesions is an essential challenge for cell-based therapy after CNS injury due to the disturbance of local environmental homeostasis. Chondroitin sulfate proteoglycan (CSPG) is obviously accumulated at the lesions and destroyed local homeostasis after CNS injury.

Calcifying fibrous tumor of stomach: A case report.

Rationale: Calcifying fibrous tumor (CFT) is a rare benign soft tissue mesenchymal neoplasm. Although the gastrointestinal (GI) tract is the most common predilection site of CFT, the clinicians, even including pathologist, generally consider it as GI stromal tumor (GIST) or other submucosal tumors such as schwannoma and leiomyoma.

Ovarian granulocytic sarcoma as the primary manifestation of acute myelogenous leukemia.

Granulocytic sarcoma (GS) usually occurs concomitantly with or after the onset of acute myeloid leukemia (AML) or other myeloproliferative disorders, however, GS of the ovary as the primary manifestation of AML is exceedingly rare. To the best of our knowledge, eight cases of ovarian GS as the first sign of AML have been reported in the literature. Here, we report the ninth case: a 27-year-old female who presented with an ovarian mass without any underlying hematologic disorder.

Synchronous poorly-differentiated neuroendocrine carcinoma and gastrointestinal stromal tumor of the stomach: a case report with immunohistochemical and molecular genetic analyses of KIT and PDGFRA.

Although the stomach is the most common location for gastrointestinal stromal tumor (GIST) with co-primary tumors, the synchronous appearance of a poorly differentiated neuroendocrine carcinoma (NEC) and GIST in the stomach is extremely rare. To the best of our knowledge, this is the first case of gastric GIST coexisting with gastric NEC to be reported in the literature. The current study reports the case of a 71-year-old male with gastric poorly differentiated NEC and GIST discovered incidentally during surgical treatment of the NEC.
