Death of Sammy Yatim
The death of Sammy Yatim occurred early in the morning of July 27, 2013, in Toronto, Ontario, Canada. Yatim, an 18-year-old Toronto male armed with a switchblade knife, was shot at nine times, and was hit by eight of the shots fired by 30-year-old Toronto Police Service (TPS) officer James Forcillo. He later died from the injuries. The incident occurred after Yatim, brandishing a 12 cm (4.7 in) switchblade knife in a Toronto streetcar, advanced on a passenger, threatened other passengers, and exposed himself. The confrontation between Yatim and the police was recorded and footage of it was released publicly, prompting strong reactions across Canada. On August 19, 2013, Forcillo was charged with second-degree murder. On July 30, 2014, he was also charged with attempted murder. On January 25, 2016, he was found not guilty of second-degree murder and manslaughter, but guilty of attempted murder. On July 28, he was sentenced to six years in prison. The next day, he was granted bail pending an appeal of the court's sentence. This incident was the only time an on-duty Ontario officer was charged and convicted in the death of a person since the inception of the Special Investigations Unit (SIU) in 1990.

Apostles in Christianity
In Christian theology and ecclesiology, apostles, particularly the Twelve Apostles (also known as the Twelve Disciples or simply the Twelve), were the primary disciples of Jesus according to the New Testament. During the life and ministry of Jesus in the 1st century AD, the apostles were his closest followers and became the primary teachers of the gospel message of Jesus. There is also an Eastern Christian tradition derived from the Gospel of Luke of there having been as many as seventy apostles during the time of Jesus' ministry. The commissioning of the Twelve Apostles during the ministry of Jesus is recorded in the Synoptic Gospels. After his resurrection, Jesus sent eleven of them (minus Judas Iscariot, who by then had died) by the Great Commission to spread his teachings to all nations. This event has been called the Dispersion of the Apostles. In the Pauline epistles, Paul, although not one of the original twelve, described himself as an apostle, saying he was called by the resurrected Jesus himself during his Road to Damascus event. He later describes himself as "the apostle of the Gentiles". In the Book of Acts he and Barnabas were allotted the roles of apostle in the church. In modern usage, missionaries under Pentecostal movements often refer to themselves as apostles, a practice which stems from the Latin equivalent of apostle, i.e. missio, the source of the English word missionary. For example, Saint Patrick (AD 373–463) was the "Apostle of Ireland", Saint Boniface (680–755) was the "Apostle to the Germans", Saint José de Anchieta (1534–1597) was the "Apostle of Brazil" and Saint Peter of Betancur (1626–1667) was the "Apostle of Guatemala". The Church of Jesus Christ of Latter-Day Saints has always had, among its leadership, twelve individuals identified as apostles. Their primary role is to teach and testify of Jesus throughout the world. The period of early Christianity during the lifetimes of the apostles is called the Apostolic Age. During the 1st century AD, the apostles established churches throughout the territories of the Roman Empire and, according to tradition, through the Middle East, Africa, and India . Of the tombs of the apostles, all but two are claimed by premises of the Catholic Church, half of them located in the Diocese of Rome.

Patient Blood Management in Liver Transplant
Transfusion of blood products in orthotopic liver transplantation (OLT) significantly increases post-transplant morbidity and mortality and is associated with reduced graft survival. Based on these results, an active effort to prevent and minimize blood transfusion is required. Patient blood management is a revolutionary approach defined as a patient-centered, systematic, evidence-based approach to improve patient outcomes by managing and preserving a patient’s own blood while promoting patient safety and empowerment. This approach is based on three pillars of treatment: (1) detecting and correcting anemia and thrombocytopenia, (2) minimizing iatrogenic blood loss, detecting, and correcting coagulopathy, and (3) harnessing and increasing anemia tolerance.

Gluten-Free Bread and Bakery Products Technology
Gluten intolerance is becoming more common in the population, and patients with this intolerance must follow a gluten-free diet. Bread and other bakery products are staple foods and pose a problem in a gluten-free diet due to their short shelf life and the need to replace gluten. Naturally gluten-free cereals and pseudocereals, but also milled legumes, seeds and nuts, are being increasingly used for the preparation of gluten-free baked goods.

Epidemiology and Classification of Aortic Dissection
The aorta is the largest artery in the body, delivering oxygenated blood from the left ventricle to all organs. Dissection of the aorta is a lethal condition caused by a tear in the intimal layer of the aorta, followed by blood loss within the aortic wall and separation of the layers to full dissection. The aorta can be affected by a wide range of causes including acute conditions such as trauma and mechanical damage; and genetic conditions such as arterial hypertension, dyslipidaemia, and connective tissue disorders; all increasing the risk of dissection. Both rapid diagnostic recognition and advanced multidisciplinary treatment are critical in managing aortic dissection patients.

Responses and Mechanisms of Plants against Drought Stress
Drought is an important abiotic stress factor limiting crop productivity worldwide and its impact is increasing with climate change. Regardless of the plant growth period, drought has a deadly and yield-reducing effect on the plant at every stage of development. As with many environmental stressors, drought-exposed plants trigger a series of molecular, biochemical, and physiological responses to overcome the effect of drought stress. Currently, researchers are trying to determine the complex functioning of drought stress response in plants with different approaches. Plants are more sensitive to drought stress during certain critical stages like germination, seedling formation, flowering, fertilization, and grain formation periods. Plants have high success in reducing the effects of drought stress in vegetative development periods with the activity of tolerance mechanisms. On the other hand, drought stress during the generative period can cause irreversible losses in yield.

Hydrogen Bond
The hydrogen bond may be treated as a local stabilizing interaction that acts between the proton or the electron charge deficient region of hydrogen centre and the electron rich region that is related to one or more centres. This may be named as the two-sites hydrogen bond definition. However in numerous studies the A-H proton donating bond with the positively charged H-atom and the proton acceptor, say B, being the electron rich centre are taken into account. Thus so-called A-H∙∙∙B hydrogen bridges are often considered. In such a way the three-sites hydrogen bond definition may be proposed that the hydrogen bond is the A-H∙∙∙B local stabilizing system with the proton situated between two A and B electron rich sites, most often closer to one of them, forming the A-H covalent bond; both A and B may correspond to one or more atomic centres.

Nanobiotechnology
Nanobiotechnology, bionanotechnology, and nanobiology are terms that refer to the intersection of nanotechnology and biology. Given that the subject is one that has only emerged very recently, bionanotechnology and nanobiotechnology serve as blanket terms for various related technologies. This discipline helps to indicate the merger of biological research with various fields of nanotechnology. Concepts that are enhanced through nanobiology include: nanodevices (such as biological machines), nanoparticles, and nanoscale phenomena that occurs within the discipline of nanotechnology. This technical approach to biology allows scientists to imagine and create systems that can be used for biological research. Biologically inspired nanotechnology uses biological systems as the inspirations for technologies not yet created. However, as with nanotechnology and biotechnology, bionanotechnology does have many potential ethical issues associated with it. The most important objectives that are frequently found in nanobiology involve applying nanotools to relevant medical/biological problems and refining these applications. Developing new tools, such as peptoid nanosheets, for medical and biological purposes is another primary objective in nanotechnology. New nanotools are often made by refining the applications of the nanotools that are already being used. The imaging of native biomolecules, biological membranes, and tissues is also a major topic for nanobiology researchers. Other topics concerning nanobiology include the use of cantilever array sensors and the application of nanophotonics for manipulating molecular processes in living cells. Recently, the use of microorganisms to synthesize functional nanoparticles has been of great interest. Microorganisms can change the oxidation state of metals. These microbial processes have opened up new opportunities for us to explore novel applications, for example, the biosynthesis of metal nanomaterials. In contrast to chemical and physical methods, microbial processes for synthesizing nanomaterials can be achieved in aqueous phase under gentle and environmentally benign conditions. This approach has become an attractive focus in current green bionanotechnology research towards sustainable development.
