Standard deviation (SD) and standard error (SE) are quietly but extensively used in biomedical publications. These terms and notations are used as descriptive statistics (summarizing numerical data), and they are used as inferential statistics (estimating population parameters from samples). I review the use and misuse of SD and SE in several authoritative medical journals and make suggestions ...

We present an improved Na+-selective liquid membrane electrode for measurement of Na+ concentrations in both undiluted serum and urine. The values for urinary Na+ obtained with the ion-selective electrode agree well with those obtained with the flame photometer. The correlation gives a standard residual deviation of +/- 2.7 mmol/L over the Na+ range of 25-280 mmol/L. In serum, this direct poten...

Abstract In the current report, we studied possible inhibitors of COVID-19 from bioactive constituents Centaurea jacea using a threefold approach consisting quantum chemical, molecular docking and dynamic techniques. is perennial herb often used in folk medicines dermatological complaints fever. Moreover, anticancer, antioxidant, antibacterial antiviral properties its compounds are also reporte...

TOPIC: Critical Care TYPE: Medical Student/Resident Case Reports INTRODUCTION: Rocky Mountain spotted fever (RMSF), a tick-borne illness, and Spotted Rickettsiosis, presents with nonspecific symptoms (e.g., high fever, headache, myalgia) mortality rate in the pre-antibiotic era (20-80%) (1,2). We present patient who developed thrombotic thrombocytopenic purpura (TTP) PLASMIC SCORE: 6 points. CA...

PyMOL (http://pymol.org) is an open-source software package designed for molecular graphics visualization and modelling. The PyMOL code-base is written in the C programming language, and much of the higher-level, useraccessible functionality is coded in Python. This software engineering design endows PyMOL with a rich Python application programming interface (API), which end-users can utilize f...

Rickettsia rickettsii is an obligate intracellular tick-borne bacterium that causes Rocky Mountain Spotted Fever (RMSF), the most lethal spotted fever rickettsiosis. When an infected starving tick begins blood feeding from a vertebrate host, R. rickettsii is exposed to a temperature elevation and to components in the blood meal. These two environmental stimuli have been previously associated wi...

The unfolding kinetics of cardiotoxin analogue VI from Taiwan cobra (Naja naja atra) have been studied at 473 K, pH 7.0 in the presence of 0.1 M NaCl using molecular dynamics simulations for 50 ns. Trajectory structures stored at every 25 ps (2000 structures) were probed at molecular (RMSD and radius of gyration) and residue (RMSF, surface area accessibility and secondary structures) level reso...
