#1
Ashley Davis
In the Solar System, the surface of an icy moon is composed of irregular ice formations at cryogenic temperatures (<200 K), with an oxidized surface layer and a tenuous atmosphere at very low pressure (<10(-6) atm). A lander mission, whose aim is to collect and analyze biological samples from the surface ice, must contain a device that collects samples without refreezing liquid and without sublimation of ice. In addition, if the samples are biological in nature, then precautions must be taken to ensure the samples do not overheat or mix with the oxidized layer...

Wakako Takeda, Melissa K Melby
Eating alone is driven by social and cultural factors, not solely by individual preferences. In academic research, eating alone is often simply treated as an alternative to social, commensal eating, and little is known about the practice of eating alone itself. This study employs a cross-cultural analysis to explore social and cultural associations of eating alone. The analysis is based on 1) cultural domain data, derived from principal component analysis of freelist responses, a set of words or phrases related to the topic of eating alone; and 2) in-depth interviews with 72 young adults aged 20-40 in urban Australia and Japan...

INTRODUCTION: Spinal ankylosing disorders encompass ankylosing spondylitis (AS), disseminated hyperostosis of the spine, and end-stage spondylosis. All these result in a stiffened and frequently deformed spinal column. This makes the spinal column highly susceptible to severe injuries that are commonly associated with unfavorable outcomes. Improved understanding of the underlying disease processes and clinical comorbidities may alter the poor injury related morbidity and mortality outcomes...

We investigated the effect of variations in ice shell thickness and of the tiger stripe fractures crossing Enceladus' south polar terrain on the moon's tidal deformation by performing finite element calculations in three-dimensional geometry. The combination of thinning in the polar region and the presence of faults has a synergistic effect that leads to an increase of both the displacement and stress in the south polar terrain by an order of magnitude compared to that of the traditional model with a uniform shell thickness and without faults...

INTRODUCTION: With an increase in prescription drug spending and rising drug costs there is a need to encourage the use of generic prescription drugs. However, maximizing generic drug use is not possible without the public's positive perception and meeting their informational needs about generic drugs. Thus, improving the public's confidence in, and knowledge of generic drugs on the market is critical. The objective of this systematic review is to examine and evaluate the studies focusing on the nature and extent of key factors influencing generic drug use in the United States in order to help guide policy, education and practice interventions...

REVIEW
Mahin Hashemipour, Silva Hovsepian, Arman Ansari, Mojtaba Keikha, Pooyan Khalighinejad, Negar Niknam
Evidence from different screening programs indicated that the rate of congenital hypothyroidism (CH) was higher in pre-term and low-birth-weight (LBW) newborns than normal ones. Incomplete development of hypothalamic-pituitary axis in this group of neonates results in the delayed rise of TSH and missing cases with CH. Hence, there is a great need for a practicable systematic screening method for proper diagnosis of CH in this group of neonates. In this review, we systematically reviewed papers with the following key words ([Congenital Hypothyroidism AND Screening AND Thyroxine AND Thyroid Stimulating Hormone AND Low Birth Weight AND Premature]) in international electronic databases including PubMed, Scopus, and Google Scholar...

We report a case of a 14-year-old patient with rare dorsal sternoclavicular dislocation caused by a sports injury. The patient was admitted to our department for further investigation and treatment. After a series of examinations, an open reduction and fixation using K-wires was used as a treatment modality. A satisfactory outcome was achieved, the patient returned to full sports activity 3 months after the surgery, with no limitations of movement. The necessity of early diagnosis and treatment options of this rare injury has been discussed...

Posttraumatic pelvic nonunions in combination with malposition are uncommon in the present-day era of modern pelvic surgery. The case describes a new surgical technique for treatment of the nonunion localized to iliosacral joint. A 42-year-old polytraumatized male presented with a pelvic fracture (type 61-C2.3) associated with a complex acetabular fracture. The patient was treated and the pelvis stabilized according to damage control principles (external fixation and pelvic C-clamp) and subsequently definitively treated according to principles of current pelvic surgery...

There is a great deal of data available, in part contradictory, on the best fixation technique to use for total hip arthroplasty (THA) in hip osteoarthritis. Both the cementless and the cemented versions offer excellent long-term outcomes - if the respective technique is applied correctly. However, as far as we know, no recommendation has been made regarding cemented vs. cementless THA in primary myelofibrosis. The case described here concerns a very active 76-year-old patient with primary myelofibrosis. This is a rare hematological disease...

PURPOSE OF THE STUDY Accurate radiographic measurements are crucial in treating hallux valgus (HV). This three-dimensional deformity should not be evaluated from one joint on one plane. However, in practice, surgeons measure the deformity only on transverse dorsoplantar radiographs. We determined the amount of error associated with positioning the foot incorrectly on radiographs. MATERIAL AND METHODS To simulate incorrect positions of the foot in radiographic evaluation, we designed an angled device that can move in transverse and frontal plane...

PURPOSE OF THE STUDY Our study aimed to evaluate a group of patients who in the period from 2005 to 2014 underwent a four-corner arthrodesis of the wrist in our department. We also wanted to verify the hypothesis as to whether the use of conventional dorsal plate without the application of bone grafts leads to comparable results as the use of dorsal locking plates and routine application of bone grafts. MATERIAL AND METHODS Throughout the years 2005 to 2014 the four-corner arthrodesis of the wrist was performed in our department in a total of 62 patients, in two cases bilaterally...
