BACKGROUND: The circulating neutrophil count was commonly believed to be influenced by altitude. At present, neutrophil reference ranges (RRs) for very low birth weight (VLBW) neonates are only available from the sea level and from high altitude. This study aimed to construct RRs for neutrophils in VLBW infants in an intermediate-altitude area and assess its usefulness in evaluation for sepsis. METHODS: This was a multicenter retrospective study of 2173 VLBW infants admitted to 20 hospitals in Chongqing in southwest of China with altitude from 1000 to 2600 feet...

The auriculotemporal nerve (ATN) is a branch of the mandibular nerve and has been implicated for some migraines and its role in Frey's syndrome is well known. An adult cadaver was found to have a duplicated ATN. The anterior trunk ascended as the superficial temporal artery and gave off the branches to the temporomandibular joint, parotid gland, external acoustic meatus and temporal region and communicated with a posterior trunk of the ATN. The posterior trunk ascended via the subcutaneous tissues 1 mm anterior to the auricle and gave off the branches to the anterior auricular region, temporal region and communicated with the anterior trunk...

Flavonoids are plant-based polyphenolic biomolecules with a wide range of biological activities. Glycosylated flavonoids have drawn special attention in the industries as it improves solubility, stability, and bioactivity. Herein, we report the production of astilbin (ATN) from taxifolin (TFN) in genetically-engineered Escherichia coli BL21(DE3). The exogenously supplied TFN was converted to ATN by 3-O-rhamnosylation utilizing the endogeneous TDP-L-rhamnose in presence of UDP-glycosyltransferase (ArGT3, Gene Bank accession number: At1g30530) from Arabidopsis thaliana...

Clinical manifestations of malaria infection in vertebrate hosts arise from the multiplication of the asexual stage parasites in the blood, while the gametocytes are responsible for the transmission of the disease. Antimalarial drugs that target the blood stage parasites and transmissible gametocytes are rare, but are essentially needed for the effective control of malaria and for limiting the spread of resistance. Artemisinin and its derivatives are the current first-line antimalarials that are effective against the blood stage parasites and gametocytes, but resistance to artemisinin has now emerged and spread in various malaria endemic areas...

BACKGROUND & AIMS: Acute kidney injury (AKI) is a common complication in patients with cirrhosis that increases mortality. The most common causes of AKI in these patients are prerenal azotemia, acute tubular necrosis (ATN), and hepatorenal syndrome; it is important to determine the etiology of AKI to select the proper treatment and predict patient outcome. Urine biomarkers could be used to differentiate between patients with ATN and functional causes of AKI. We performed a systemic review and meta-analysis of published studies to determine whether urine levels of interleukin 18 (IL18) and lipocalin 2 (LCN2 or NGAL) associate with development of ATN in patients with cirrhosis...

PHSCN peptide (licensed as ATN-161) is an effective α5β1 integrin inhibitor that has advanced to phase II clinical trials to treat solid tumors. Here we developed ATN-161 functionalized self-crosslinkable and intracellularly decrosslinkable polymersomes (ATN/SCID-Ps) for highly efficient and targeted delivery of doxorubicin hydrochloride (DOX•HCl) into B16F10 melanoma-bearing C57BL/6 mice. ATN/SCID-Ps exhibited a high loading capacity of DOX•HCl. The size of DOX-loaded ATN/SCID-Ps (DOX-ATN/SCID-Ps) decreased from 150 to 88 nm with increasing ATN surface densities from 0 to 100% (mol/mol)...

To understand the phylogeny of the host insect (Thitarodes sp.) of the fungus Ophiocordyceps sinensis, we sequenced, annotated and characterized the complete mitochondrial (mt) genome of the host cadaver of a natural O. sinensis. Further, we compared the Thitarodes sp. mt genome with those of the other 7 sequenced Hepialidae and examined the phylogenetic relationships using a constructed Maximum Likelihood (ML) phylogenetic tree and mt genomic features (genetic distances and intergenic spacers). The mt genome is a circular molecule of 16,280bp in length with a high A+T content (81...

The complete mitochondrial genome (mitogenome) of Leucoma salicis (Lepidoptera: Lymantriidae) was sequenced and annotated. It is a circular molecule of 15,334 bp, containing the 37 genes usually present in insect mitogenomes. All protein-coding genes (PCGs) are initiated by ATN codons, other than cox1, which is initiated by CGA. Three of the 13 PCGs had an incomplete termination codon, T or TA, while the others terminated with TAA. The relative synonymous codon usage of the 13 protein-coding genes (PCGs) was consistent with those of published lepidopteran sequences...

Traumatic Brain Injury (TBI) is one of the leading causes of death and disability in the population worldwide, with a broad spectrum of symptoms and disabilities. Post-traumatic hyperexcitability is one of the most common neurological disorders that affect people after a head injury. A reliable animal model of post-traumatic hyperexcitability induced by TBI which allows one to test effective treatment strategies has yet to be developed. To address these issues, in the present study, we tested human ES-derived neural stem cell transplantation in an animal model of post-traumatic hyperexcitability in which the brain injury was produced in one hemisphere of immunodeficient athymic nude (ATN) rats by controlled cortical impact (CCI) and spontaneous seizures were produced by repeated electrical stimulation (kindling) in the contralateral hemisphere...

Zoledronate is a highly potent bisphosphonate widely used in the treatment of postmenopausal osteoporosis. We report the first occurrence of toxic acute tubular necrosis (ATN) following treatment with zoledronate in a patient with osteoporosis. A 63-year-old Caucasian female with rheumatoid arthritis on anti-immune agents received a single dose of zoledronic acid (reclast) for worsening osteoporosis. Twelve days later, she developed renal failure with a rise in serum creatinine from a baseline level of 1.1 mg/dL to 5...

The regeneration of injured tubular cell occurs primarily from intrinsic renal stem/progenitor cells (RSCs) labeled with CD24 and CD133 after acute tubular necrosis (ATN). Bmi-1 plays a crucial role in regulating self-renewal, differentiation and aging of multiple adult stem cells and progenitor cells. Bmi-1 was rapidly elevated in the induction of adult kidney regeneration by renal injury. To determine whether Bmi-1 maintained mobilization of RSCs in the protection from ATN, glycerol-rhabdomyolysis-induced ATN were performed in wild type (WT) and Bmi-1-deficient (Bmi-1(-/-)) mice...

Triple-negative breast cancers (TNBCs) are the most aggressive and hard-to-treat breast tumors with poor prognosis, and exploration for novel therapeutic drugs is impending. Arctigenin (Atn), a bioactive lignan isolated from seeds of Arctium lappa L, has been reported to inhibit many cancer types; however, the effect of Atn on TNBC remains unclear. In this study, we demonstrated that Atn decreased proliferation, and induced apoptosis in TNBC cells. Furthermore, we explored the underlying mechanism of Atn inhibition on TNBC cells...

COMPARATIVE STUDY
Wen-Yuan Fang, Zheng-Liang Wang, Chao Li, Xiao-Qing Yang, Xiao-Ping Yu
The complete mitogenome of the jumping spider Carrhotus xanthogramma was determined and comparative analysis among four salticid mitogenomes was conducted. The circular genome is 14,563 bp in size and contains a complete set of genes that usually present in the metazoa. All of the 13 protein-coding genes begin with a typical ATN codon and stop with the canonical stop codons, except for ND4 and ND4L genes with an incomplete stop codon T. All of the tRNAs cannot be formed the fully paired acceptor stems and seven out of them cannot be folded into the typical cloverleaf-shaped secondary structures...

REVIEW
Keiko Hosohata
The kidney plays a primary role in maintaining homeostasis and detoxification of numerous hydrophilic xenobiotics as well as endogenous compounds. Because the kidney is exposed to a larger proportion and higher concentration of drugs and toxins than other organs through the secretion of ionic drugs by tubular organic ion transporters across the luminal membranes of renal tubular epithelial cells, and through the reabsorption of filtered toxins into the lumen of the tubule, these cells are at greater risk for injury...

BACKGROUND/AIMS: Acute tubular necrosis (ATN), a leading cause of acute kidney injury (AKI), is associated with decreased survival and increased progression of chronic kidney disease. A barrier to improving the clinical outcomes is the incomplete understanding of the pathogenesis of AKI. Our objective is to test the hypothesis that intrarenal renin-angiotensin system (RAS) is overexpressed in patients with ATN and could be an indicator of ATN severity. METHODS: A transversal study was conducted in patients with biopsy-proven ATN...
