Effect of Nitrate Ions on Acidithiobacillus ferrooxidans-Mediated Bio-oxidation of Ferrous Ions and Pyrite.

Exploring the effects of nitrate ions (NO) on the bio-oxidation of Fe and pyrite will help reveal the actual mechanism of acid mine drainage (AMD) production. Long period shaking flask experiments were carried out in order to assess the effect of NO on the Acidithiobacillus ferrooxidans LX5 (A. ferrooxidans LX5)-mediated bio-oxidation of Fe and pyrite.

[Clinical Characteristics of Autoimmune Disease with Dual Seropositive Antibodies of Leucine-rich Glioma Inactivated 1 and Contactin-associated Protein 2].

Objective To explore the clinical characteristics of autoimmune disease with dual seropositive antibodies of leucine-rich glioma inactivated 1(LGI1)and contactin-associated protein 2(Caspr2).Methods The clinical data of seven patients with dual seropositive LGI1 and Caspr2 antibodies who were admitted to the Neurology Department of Peking Union Medical College Hospital from July 2014 to December 2017 were retrospectively analyzed.Results Central,peripheral and autonomic nervous systems were all involved in the seven cases;100%(7/7)presented with insomnia,myokymia,neuropahic pain and hyperhydrosis;71%(5/7)showed memory decline or psychiatric and behavioral symptoms;57%(4/7)had urinary hesitation or constipation;and 43%(3/7)had seizure.

Severe thoracic trauma caused left pneumonectomy complicated by right traumatic wet lung, reversed by extracorporeal membrane oxygenation support-a case report.

Background: Double lumen intubation and one-lung ventilation should be applied without delay in cases of traumatic main bronchial rupture. In most cases, when the patients' vital signs have been stabilized, the repair can be performed. However, when one-lung ventilation is complicated by traumatic wet lung, the mortality rate is likely to be much higher.

Effect of long-term fertilization on wheat yield under different precipitation patterns.

Rational application of nitrogen and phosphorus is one of the main pathways to enhance wheat yield. The optimum dosage of nitrogen and phosphorus used in different precipitation patterns was studied using the binary quadratic regression equation, which could provide a basis for fertilization of wheat in Loess Plateau. The results showed that the amount of nitrogen and phosphorus ferti-lizer required for the maximum yield was dependent on precipitation patterns.

The Efficacy and Immunomodulatory Effects of Ulinastatin and Thymosin α1 for Sepsis: A Systematic Review and Meta-Analysis.

Objective. To systematically review the efficacy and potential immunomodulatory effect of ulinastatin combined with thymosin α1 (UTI) for sepsis. Design.

Factors that affect sleep quality: perceptions made by patients in the intensive care unit after thoracic surgery.

Objective: This study identifies factors affecting sleep patterns among thoracic surgery patients in the intensive care unit (ICU) and compares the perceptions of sleep-disturbing factors between nurses and patients.

Methods: One hundred and fifty-two patients and 40 nurses were surveyed using the Pittsburgh Sleep Quality Index (PSQI) and self-designed questionnaires (for patients and nurses). All statistical analyses were carried out by SPSS, and the following statistical methods were used to evaluate the data: chi-squared test and logistic regression.

Scavenging of BHCs and DDTs from soil by thermal desorption and solvent washing.

Intensive remediation of abandoned former organochlorine pesticides (OCPs) manufacturing areas is necessary because the central and surrounding soils contaminated by OCPs are harmful to crop production and food safety. Organochlorine and its residues are persistent in environments and difficult to remove from contaminated soils due to their low solubility and higher sorption to the soils. We performed a comprehensive study on the remediation of OCPs-contaminated soils using thermal desorption technique and solvent washing approaches.
