Experimental serological tests were developed to determine anti-tularensis antibodies in humans in immunochromatography formats (LF-test LPS Ft15) and enzyme immunoassay (ELISA LPS Ft15) using as an antigen highly purified LPS F. tularensis 15 NIIEG. Analysis was conducted of the sensitivity and specificity of the developed tests and commercial tularemia antigen «RNGA-Tul-AG» (production Stavropol research anti-plague Institute) in comparison with the commercial reference antigen, registered in the Russian Federation for the quantitative determination of human IgG tularemia - «ELISA classic Francisella tularensis IgG» SERION, Germany (IgG SERION ELISA). A study of human blood serum vaccinated against tularemia showed that the sensitivity and specificity of detection of anti-tularemia antibodies by «ELISA LPS Ft15» were 97.7 and 100%, compared with «ELISA IgG series». When determining antitularemia antibodies with the diagnosis «LF-test LPS Ft15», these parameters were compared to «ELISA IgG series» 94.3 and 100%. The sensitivity and specificity of «RNGA-Tul-AG» made compared to the «IgG ELISA, SERION» of 59.1% and 80%.

Background: Most oligonucleotide bioanalytical assays currently only quantify the pharmacologically-active antisense strand, though there have been recent efforts to simultaneously quantify the sense strand using hybridization ELISA or solid phase extraction LC-MS. Hybrid LC-MS, which offers both high sensitivity and specificity unlike the currently used platforms, has not been applied to quantify both siRNA strands simultaneously.
Materials & Methods: A hybrid LC-MS assay utilizing LNA capture probes was developed and applied to quantify both strands of a 21-mer lipid-conjugated siRNA (SIR-3) using tandem mass spectrometry (MS/MS).

Background: Risk prediction tools for acutely ill children have been developed in high- and low-income settings, but few are validated or incorporated into clinical guidelines. We aimed to assess the performance of existing paediatric early warning scores for use in low- and middle-income countries using clinical data from a recent large multi-country study in Africa and South-Asia.
Methods: We used data (children across three nutritional strata) from the Childhood Acute Illness and Nutrition (CHAIN) Network cohort study (n = 3101).

Introduction: Gallium-68 prostate-specific membrane antigen positron emission tomography (Ga-PSMA PET) is being increasingly used in patients with prostate cancer (PCa) for the staging and detection of lymph node (LN) metastases, despite a lack of prospective, validated evidence. We aimed to investigate the relationship between the PSMA PET findings (maximum standardized uptake [SUV] value) and the final histopathology results (Gleason Grade [GG], and LN positivity) in patients undergoing radical prostatectomy.
Methods: This is a single centre, prospective, observational study of 63 consecutive eligible patients treated at a tertiary care centre in India.

Introduction: Recently, the Prostate Imaging Reporting and Data System - 3 lesions (PI-RADS 3) have been sub classified into "3a" - lesions with a volume of <0.5 mL and "3b" - lesions exceeding 0.5 mL, whereas the prostate-specific antigen density (PSAD) is an established adjunct tool for predicting clinically significant prostate cancer (csPCa).

Neonatal sepsis (NS) is highly likely to cause death; however, early diagnosis of NS is still a great challenge. This study aimed to determine the diagnostic values of IL-6, IL-8, and serum amyloid A (SAA) in NS patients. C-Reactive protein (CRP), procalcitonin (PCT), interleukin (IL)-6, IL-8, and SAA were detected in 120 infants with NS (60 premature infants [NS-PIs] and 60 term infants [NS-TIs]).
