Method: The materials used in the study were: 1) Macor, (Precision Ceramics UK) 2) BioMinF: 500gm of glass frit (Cera Dynamics Ltd, UK) and 3) Sylc: Sylc 45S5 glass (Velopex International, UK). An AquaCare Air Abrasion & Polishing System (Velopex) with a hand piece with a 0.8 mm diameter tip was used with a 2mm thick Macor sheet with a feed rate of 1 and an air pressure of 2 bar. The BioMinF glass was milled for 45 seconds in five batches each containing 100 gm of BioMinF frit using a milling machine (Gy-Ro Mill, Glen Creston, and London). The angular particles produced were separated using different sieves to produce <38 micron, 38-63 microns, 63-80 microns, 80-125 microns and 125-250 microns particle size(s) respectively. -

Copper is known to be an antibacterial agent, which could potentially be a safer alternative to doping materials with antibiotics. Additionally, the structural effects of copper in the glass were studied, as the glass structure plays an important role in its bioactivity in the physiological solutions. This leads to the possibility of achieving antibacterial glass that can serve as a bioactive glass for skeletal tissue. bioRxiv preprint doi: https://doi.org/10.1101/2020.01.24.918524; this version posted January 25, 2020.

Abstracts 1-68 Relate to the Sunday Program Biology 1. 100 Years of Genetics William Sofer, Rutgers University, Piscataway, NJ Almost exactly 100 years ago, Thomas Hunt Morgan and his coworkers at Columbia University began studying a small fly, Drosophila melanogaster, in an effort to learn something about the laws of heredity. After a while, they found a single white-eyed male among many thousands of normal red-eyed males and females. The analysis of the offspring that resulted from crossing this mutant male with red-eyed females led the way to the discovery of what determines whether an individual becomes a male or a female, and the relationship of chromosomes and genes. 2. Streptomycin - Antibiotics from the Ground Up Douglas Eveleigh, Rutgers University, New Brunswick, NJ Antibiotics are part of everyday living. We benefit from their use through prevention of infection of cuts and scratches, control of diseases such as typhoid, cholera and potentially of bioterrorist's pathogens, besides allowing the marvels of complex surgeries. Antibiotics are a wondrous medical weapon. But where do they come from? The unlikely answer is soil. Soil is home to a teeming population of insects and roots, plus billions of microbes - billions. But life is not harmonious in soil. Some microbes have evolved strategies to dominate their territory; one strategem is the production of antibiotics. In the 1940s, Selman Waksman, with his research team at Rutgers University, began the first ever search for such antibiotic producing micro-organisms amidst the thousands of soil microbes. The first antibiotics they discovered killed microbes but were toxic to humans. -

Received: 19 February 2018; Accepted: 13 March 2018; Published: 16 March 2018 Abstract: Nowadays, bioactive glasses (BGs) are mainly used to improve and support the healing process of osseous defects deriving from traumatic events, tumor removal, congenital pathologies, implant revisions, or infections. In the past, several approaches have been proposed in the replacement of extensive bone defects, each one with its own advantages and drawbacks. As a result, the need for synthetic bone grafts is still a remarkable clinical challenge since more than 1 million bone-graft surgical operations are annually performed worldwide. Moreover, recent studies show the effectiveness of BGs in the regeneration of soft tissues, too. Often, surgical criteria do not match the engineering ones and, thus, a compromise is required for getting closer to an ideal outcome in terms of good regeneration, mechanical support, and biocompatibility in contact with living tissues. The aim of the present review is providing a general overview of BGs, with particular reference to their use in clinics over the last decades and the latest synthesis/processing methods. -
