REVIEW
Yasaman Aghazadeh, Maria Cristina Nostro
PURPOSE OF THE REVIEW: Type 1 diabetes (T1D) is defined by an autoimmune destruction of insulin producing β-cells located in the endocrine part of the pancreas, the islets of Langerhans. As exogenous insulin administration fails at preventing severe complications associated with this disease, cell replacement therapies are being considered as a means to treat T1D. The purpose of this manuscript is to review the challenges associated with current strategies and discuss the potential of stem cell therapy for the treatment of T1D...

REVIEW
Paula Nunes-Hasler, Nicolas Demaurex
Phagocytosis is an essential mechanism through which innate immune cells ingest foreign material that is either destroyed or used to generate and present antigens and initiate adaptive immune responses. While a role for the ER during phagosome biogenesis has been recognized, whether fusion with ER cisternae or vesicular derivatives occurs has been the source of much contention. Membrane contact sites (MCS) are tight appositions between ER membranes and various organelles that coordinate multiple functions including localized signalling, lipid transfer and trafficking...

Missile embolus to the heart, although uncommon, is one of the most challenging scenarios in trauma. We describe a 36-year-old man who presented with a gunshot wound to the left chest and a chest x-ray revealing a foreign body in the mediastinum. A median sternotomy was performed and an injury to the left ventricle was identified. After intraoperative echocardiography and fluoroscopy confirmed a foreign body in the aortic root, cardiopulmonary bypass was implemented. A bullet was retrieved from the noncoronary sinus of the aortic valve...

BACKGROUND: Migrants resident in Italy exceeded 5 million in 2015, representing 8.2% of the resident population. The study of the mechanisms that explain the differential health of migrant workers (as a whole and for specific nationalities) has been identified as a priority for research. The international literature has shown that migrant workers have a higher risk of total and fatal injury than natives, but some results are conflicting. The aim of this paper is to study the injury risk differentials between migrants, born in countries with strong migratory pressure (SMPC), and workers born in high income countries (HIC), taking into account individual and firm characteristics and job tenure...

Imaging of the orbit plays an important role in the workup of orbital emergencies. Orbital imaging is particularly useful in the emergency department, where clinical history and physical examination may be limited or delayed until the exclusion or treatment of more life-threatening conditions. Cross-sectional orbital imaging with multidetector computed tomography (CT) and magnetic resonance (MR) imaging is commonly performed in addition to ultrasonography. In an emergent setting, CT is the preferred modality when evaluating for intraorbital foreign bodies, fractures, or calcifications within a mass lesion...

Jackson S Turner, Matangi Marthi, Zachary L Benet, Irina Grigorova
The perspective that naive B-cell recognition of antigen in the absence of T-cell help causes cell death or anergy is supported by in vivo studies of B cells that are continuously exposed to self-antigens. However, intravital imaging suggests that early B-cell recognition of large foreign antigens may be transient. Whether B cells are tolerized or can be recruited into humoural immune responses following such encounters is not clear. Here we show that in the presence of T-cell help, single transient antigen acquisition is sufficient to recruit B cells into the germinal centre and induce memory and plasma cell responses...

Chloroplasts play a great role for sustained wellbeing of life on the planet. They have the power and raw materials that can be used as sophisticated biological factories. They are rich in energy as they have lots of pigment-protein complexes capable of collecting sunlight, in sugar produced by photosynthesis and in minerals imported from the plant cell. Chloroplast genome transformation offers multiple advantages over nuclear genome which among others, include: integration of the transgene via homologus recombination that enables to eliminate gene silencing and position effect, higher level of transgene expression resulting into higher accumulations of foreign proteins, and significant reduction in environmental dispersion of the transgene due to maternal inheritance which helps to minimize the major critic of plant genetic engineering...

REVIEW
Ying Jie Ma, Bok Luel Lee, Peter Garred
The complement system is an innate immune defense machinery comprising components that deploy rapid immune responses and provide efficient protection against foreign invaders and unwanted host elements. The complement system is activated upon recognition of pathogenic microorganisms or altered self-cells by exclusive pattern recognition molecules (PRMs), such as collectins, ficolins and pentraxins. Recent accumulating evidence shows that the different classes of effector PRMs build up a co-operative network and exert synergistic effects on complement activation...

Intracellular delivery of foreign DNA probes sharply increases the efficiency of various biodetection protocols. Spherical nucleic acid (SNA) conjugate is a new type of probe that consists of a dense oligonucleotide shell attached typically to a gold nanoparticle core. They are widely used as novel labels for in vitro biodetection and intracellular assay. However, the degradation of foreign DNA still remains a challenge that can cause significant signal leakage (false positive signal). Hence, the site and behavior of intracellular degradation need to be investigated...

BACKGROUND: Multiple sclerosis is a central nervous system demyelinating disease with unknown etiology. However, it is believed to be a multifactorial disease resulting from an interaction of genetic and environmental factors. Immigrant studies have been performed to provide a better view of the pattern of this interaction. We aimed to report the prevalence of MS Afghan immigrants of Isfahan, a population who share the same environment as Isfahan residents but with different genetic backgrounds...

Asian Americans are commonly perceived as perpetual foreigners and, therefore, not "true" Americans. Asian Americans report inquiries about nationality and English abilities as the most common forms of racial microaggressions perpetrated by White Americans (Sue, 2015). Race theorists assert that these microaggressions are race-related and marginalize Asian Americans. Scholars have claimed that these subtle acts are harmful, yet only a few studies have uncovered the mechanisms by which racial microaggressions affect mental and physical well-being (Ong, Burrow, Fuller-Rowell, Ja, & Sue, 2013; Wong, Derthick, David, Saw, & Okazaki, 2013)...

Nano-droplets on a foreign substrate have received increasing attention because of their technological possible applications, for instance to catalyse the growth of nanowires. In some cases the droplets can move as a result of a reaction with the substrate. In this work we show that the substrate orientation, the surface morphology and the shape of the pits etched in the substrate by the droplets affect the droplet motion, so that a single mechanism (droplet-induced substrate dissolution) may lead to several unexpected droplet dynamics...

BACKGROUND: Gastric wall abscesses are rare, but mortality rates from this type of gastritis are high. A foreign body or mucosal damage is often the cause of the abscess. Most patients have nonspecific symptoms, including general malaise and abdominal pain, sometimes accompanied by fever and weight loss. CASE DESCRIPTION: After various tests a 45-year-old man with epigastric pain was shown to have a gastric wall abscess. After endoscopic drainage of the abscess, followed by intravenous antibiotics, he made a complete recovery...

The wound healing process initiates after injury to a tissue and involves a series of orchestrated events to minimize the invasion of foreign matters such as bacteria and efficiently regenerate the damaged tissue. A variety of cells must be recruited to the tissue during wound healing. However, this process is severely disrupted in patients suffering from chronic illness, including diabetes, leading to impaired healing or non-healing wounds. Current avenues of treatment include negative-pressure therapy, wound debridement, growth factor replacement, and cell-based therapies...
