5 log μg/lens), cholesterol (1.5 ± 0.3 vs 1.1 ± 0.3 log μg/lens) and triolein (0.3 ± 0.2 vs 0.1 ± 0.1 log μg/lens) (all p less then 0.002). The amount of cholesteryl ester deposited was greatest (p = 0.0001), followed by cholesterol, then triolein, for both the asymptomatic and symptomatic groups (both p = 0.0001). Conclusion This study demonstrated that the asymptomatic group deposited a significantly greater amount of lipid on their CL. Although lipid levels measured are considered low to trigger any observable clinical deposition, they may influence other clinical outcomes, particularly comfort.Background Thrombolytic therapy is widely accepted for massive pulmonary embolism (PE) due to the high mortality risk associated with standard anticoagulation alone. Its role in submassive PE, however, has remained controversial. We aimed to evaluate whether the selective use of systemic thrombolytic therapy with intravenous tissue plasminogen activator (IV-tPA) improves the survival of patients with submassive PE at increased risk for clinical deterioration. Methods A total of 184 consecutive patients diagnosed with acute PE by chest thoracic angiography (CTA) were included in a retrospective study. Pulmonary artery obstruction and right/left ventricular dysfunction were evaluated by CTA and echocardiography. Medical history and simplified PE Severity Index (sPESI) were assessed at diagnosis. Hemodynamic and respiratory status were recorded at diagnosis, admission to pulmonary unit and prior to thrombolytic therapy. Patient survival was assessed at 30 of 90 days from diagnosis by CTA. Results All low risk patients (36%) per sPESI survived. Among the 117 remaining patients, 31% received IV-tPA. Respiratory failure was associated with decreased age-adjusted survival (P = 0.005). Among patients with respiratory failure selected for IV-tPA, age-adjusted survival was improved significantly compared to others (P = 0.043). Conclusions Thrombolytic therapy for hemodynamically stable PE patients with respiratory failure may improve survival.

The miR-17-92 gene cluster is a highly conserved oncogene cluster encoding 6 miRNAs miR-17, miR-18a, miR-19a, miR-19b-1, miR-20a and miR-92a. This study explored whether these miRNAs can be used as diagnostic markers for non-small-cell lung cancer (NSCLC). Methods Serum samples were collected from healthy subjects (n = 23) and NSCLC patients at various stages (n = 74). Serum RNA was extracted by the TRIzol-glycogen method, and cDNA libraries were constructed by reverse transcription. Quantitative real-time polymerase chain reaction (qRT-PCR) was utilized to detect the expression levels of the 6 miRNAs. Results The expression levels of the 6 miRNAs varied in different stages of NSCLC. Thus, 2 receiver operating characteristic (ROC) curves, that is, normal subjects and stage I-III patients and normal subjects and stage IV patients, of each miRNA were established to determine the interval of normal ΔCt values. see more The 2 areas under the curve (AUCs) of each miRNA were investigated (miR-17 0.8097 and 1.000; miR-18a 0.7388 and 0.9907; miR-19a/19b 0.8451 and 0.5104; miR-20a 0.8975 and 1.000; miR-92a 0.8097 and 0.8342). In addition, a high positive correlation was discovered between miR-17 and miR-20a expression. Combining these 2 miRNAs can improve the screening effect of NSCLC. Conclusion The miR-17-92 gene cluster can likely serve as a diagnostic marker in NSCLC.Background Transient hypocalcemia due to parathyroid gland or vessel manipulation is a common complication following thyroidectomy. Considering the role of 25-hydroxyvitamin D (25(OH)D) in calcium hemostasis, this study aimed to evaluate the effect of preoperative vitamin D supplementation on hypocalcemia incidence in thyroidectomy patients. Methods In this randomized clinical trial, 100 patients scheduled for total thyroidectomy and suffering from preoperative moderate or severe vitamin D deficiency were enrolled. Patients were randomly allocated to either study or control groups using the sealed envelope method. Patients in the study group received vitamin D3 50,000-unit pearl weekly for 4 weeks prior to the operation. The control group received placebo. Total and ionized serum calcium levels were checked before surgery, the day after surgery, and 2 weeks postoperatively. Results No significant difference was observed in terms of demographic data. During serial total calcium checks (5 episodes), total calcium levels changed significantly in patients who had received vitamin D supplements compared to the control group (P = 0.043). Symptomatic hypocalcemia incidence was significantly lower in patients supplemented with 25-hydroxyvitamin D (25(OH)D) (P = 0.04). Also, the requirement for intravenous calcium administration in order to treat the hypocalcemia symptoms was significantly lower in the study in comparison to the control group (P = 0.03). Conclusions Vitamin D supplementation in patients with vitamin D deficiency might lead to a lower incidence of early-onset symptomatic hypocalcemia; hence, requiring less calcium supplementation for the management of hypocalcemia.Neuronal apoptosis caused by amyloid-beta (Aβ) overproduction is one of the most important pathological features in Alzheimer's disease (AD). Endoplasmic reticulum (ER) stress induced by Aβ overload plays a critical role in this process. Bis(ethylmaltolato)oxidovanadium (IV) (BEOV), a vanadium compound which had been regarded as peroxisome proliferator-activated receptor γ (PPARγ) agonist, was reported to exert an antagonistic effect on ER stress. In this study, we tested whether BEOV could ameliorate the Aβ-induced neuronal apoptosis by inhibiting ER stress. It was observed that BEOV treatment ameliorated both tunicamycin-induced and/or Aβ-induced ER stress and neurotoxicity in a dose-dependent manner through downgrading ER stress-associated and apoptosis-associated proteins in primary hippocampal neurons. Consistent with in vitro results, BEOV also reduced ER stress and inhibited neuronal apoptosis in hippocampi and cortexes of transgenic AD model mice. Moreover, by adopting GW9662 and salubrinal, the inhibitor of PPARγ and hyperphosphorylated eukaryotic translation initiation factor 2α, respectively, we further confirmed that BEOV alleviated Aβ-induced ER stress and neuronal apoptosis in primary hippocampal neurons by activating PPARγ.
