Case Reports: Hepatic Sclerosing Hemangioma: A Diagnostic Dilemma!

Haemangiomas are the most common benign incidentally detected hepatic lesions with a prevalence of ~20%. Most of them have typical imaging features and are easily diagnosed on triple phase studies. These are capillary, flash and giant hemangioma. Another subset of haemangiomas are Sclerosing hemangiomas or atypical haemangioma; these are sclerosed, thrombosed and/or hyalinised due to which these are heterogenous and show varied appearance making them difficult to diagnose.

Can Bullet Characteristics Link a Bullet to a Manufacturer?

This paper was written to understand if there is a way to identify bullet manufacturer based solely on the shape and characteristics of the bullet. Traditional methods of bullet identification are to use a bullet comparison microscope and look for tool marks and rifling to link it to one particular gun. Cartridge case identification is a lot easier to link to the manufacturer being that there is already some identifying information of the breech face such as the bullet size (9mm), the gun manufacturer (SW-Smith and Wesson), and the trigger pin impression. This research is being done to find an alternative method of bullet identification in the event there are no cartridges left at a crime scene nor does the bullet have sufficient tool marks or rifling to link to a specific gun.

Homology Modelled Structure of Glutaredoxin 2 from Chlamydomonas reinhardtii

Different types of Glutaredoxins (GRXs) that play a major role in cellular anti-oxidative reactions have been studied for their structure and function from various organisms. Glutathione (GSH), an anti-oxidant with several medical benefits, binds to GRXs. This work has structurally characterized GRX2 from C. reinhardtii (CrGRX2) using biophysical, molecular modelling, and isothermal titration calorimetry (ITC) techniques. CrGRX2 adopts the classical GRX-Trx fold consisting of five β-strands surrounded by four α-helices that bind to GSH with moderate strength through a cysteine residue. The residues involved in the interaction closely match with those observed for E. coli and human counterparts, indicating that the cellular GSH-GRXs antioxidant system is highly conserved.

Anodizing for Design and Function

Two basic reactions occur during the anodizing of aluminum: 1) the aluminum is consumed and 2) an oxide grows. By accepting this statement as true, the anodizing process can be viewed as a corrosion process, and anodizing can be modeled using the Tafel Equation. Anodizing process parameters of electrolyte chemistry and concentration, temperature, aluminum substrate resistance and current density are presented as they relate to the Tafel Equation and how they impact the anodic aluminum oxide structure and properties. Understanding this relationship is consequent in making anodizing an engineering process, one that enables tuning the structure such that it yields distinct characteristics to fulfill design and application requirements.

Electronic-nose Applications in Forensic Science and for Analysis of Volatile Biomarkers in the Human Breath

The application of electronic-nose (E-nose) technologies in forensic science is a recent new development following a long history of progress in the development of diverse applications in the related biomedical and pharmaceutical fields. Data from forensic analyses must satisfy the needs and requirements of both the scientific and legal communities. The type of data collected from electronic-nose devices provides a means of identifying specific types of information about the chemical nature of evidentiary objects and samples under investigation using aroma signature profiles of complex gaseous mixtures containing volatile organic compounds (VOCs) released from manufactured products and parts of the human body. E-nose analyses also provide useful qualitative information about the physicochemical characteristics and metabolic conditions of human subjects without the need for time-consuming analyses to identify all chemical components in human-derived volatile mixtures.

The Effects of the Film Thickness and Roughness in the Anodization Process of Very Thin Aluminum Films

The anodization of aluminum foils having micrometer thickness is a common process and results in hexagonally self-ordered alumina membranes. However, anodic aluminum oxide (AAO) membranes fabricated from nanometer-thin films present new challenges to the anodization process, since aluminum films adheres poorly on supporting substrates and the smoothness of the film is highly related to the kind of substrate.
