1.Antemortem vitreous potassium may strengthen postmortem interval estimates.
Kokavec J1, Min SH2, Tan MH2, Gilhotra JS2, Newland HS2, Durkin SR2, Casson RJ2. Forensic Sci Int. 2016 Mar 19. pii: S0379-0738(16)30113-X. doi: 10.1016/j.forsciint.2016.03.027. [Epub ahead of print]
The purpose of this letter is to highlight that postmortem interval estimates using vitreous potassium concentrations may be further optimised by calibration against antemortem vitreous samples.
2.Transfer factors of natural radionuclides and 137Cs from soil to plants used in traditional medicine in central Serbia.

Transfer factors of natural radionuclides and 137Cs from soil to plants used in traditional medicine were determined. The transfer factors (TF) were calculated as Bq kg-1 of dry plant per Bq kg-1 of dry soil. Mass activity concentrations of 226Ra, 232Th, 40K and 137Cs in soil and plant samples were measured with high purity germanium detector (HPGe). The concentrations of As, Co, Cr, Cu, Mn, Ni, Pb and Zn were determined, as well as the cation exchange capacity (CEC) and the content of exchangeable cations (Ca, Mg, K, Na). Wide ranges of values were obtained for all the metals, especially for Cr and Ni. The Absalom model was used for determination of the amount of 137Cs transferred from soil to plant based on soil characteristics such as pH, exchangeable potassium, humus and clay contents. The estimated transfer factors were in the range from 0.011 to 0.307 with an arithmetic mean of 0.071, median of 0.050, geometric mean of 0.053 and geometric standard deviation (GSD) of 2.
3.Successful Treatment of Sodium Oxalate Induced Urolithiasis with HelichrysumFlowers.

ETHNOPHARMACOLOGICAL RELEVANCE: Helichrysum (Asteraceae) flowers, known as "altın otu, yayla çiçeği, kudama çiçeği", are widely used to remove kidney stones and for their diuretic properties in Turkey.
4.Efficacy and Safety of Vasopressin Receptor Antagonists for Euvolemic or Hypervolemic Hyponatremia: A Meta-Analysis.
Zhang X1, Zhao M, Du W, Zu D, Sun Y, Xiang R, Yang J. Medicine (Baltimore). 2016 Apr;95(15):e3310. doi: 10.1097/MD.0000000000003310.
Hyponatremia, defined as a nonartifactual serum sodium level <135 mmol/L, is the most common fluid and electrolyte abnormality in clinical practice. Traditional managements (fluid restriction, hypertonic saline and loop diuretics, etc.) are difficult to maintain or ineffective. Recently, vasopressin receptor antagonists (VRAs) have shown promise for the treatment of hyponatremia.We aimed to conduct a meta-analysis to evaluate the efficacy and safety of VRAs in patients with euvolemic or hypervolemic hyponatremia. We searched Pubmed, Cochrane Library, Web of Science and Springer, etc. (latest search on June 4, 2015) for English publications with randomized controlled trials. Two authors independently screened the citations and extracted data. We calculated pooled relative risk (RR), risk difference (RD), weighted mean difference (WMD) or standard mean difference (SMD), and 95% confidence intervals (CIs) by using random and fixed effect models.
