Enhanced oil recovery from fractured carbonate reservoirs using nanoparticles with low salinity water and surfactant: A review on experimental and simulation studies.

May 27, 2021

Nearly half of the world's oil reserves are found in carbonate reservoirs, which have heterogeneous formation characteristics and are naturally fractured. Because of the permeability contrast between ...

The prevalence of serious pathology in musculoskeletal physiotherapy patients - a nationwide register-based cohort study.

May 27, 2021

Musculoskeletal conditions are the single largest contributor to years lived with disability worldwide. Most musculoskeletal conditions can be managed in primary care, but for a small proportion of th...

Cranial Suture Evaluation in Pediatric Head Trauma: Importance in Differentiating Abusive From Accidental Injury.

May 27, 2021

Pediatric skull fracture association with the cranial sutures (crossing, widening, or contacting 2 or more cranial sutures) is suggestive of abusive injury. We studied the efficacy of head computed to...

A Multicenter, Randomized, Controlled Trial for Assessing the Usefulness of Suppressing Thyroid Stimulating Hormone Target Levels after Thyroid Lobectomy in Low to Intermediate Risk Thyroid Cancer Patients (MASTER): A Study Protocol.

May 27, 2021

Postoperative thyroid stimulating hormone (TSH) suppression therapy is recommended for patients with intermediate- and high-risk differentiated thyroid cancer to prevent the recurrence of thyroid canc...

Proximal Humerus Fractures Treated with an Intramedullary Cage and Plate: Clinical and Radiographic Outcomes at a Minimum of 1 Year Post Operatively.

May 24, 2021

Proximal humerus fractures are common injuries. Although certain fracture types may benefit from surgery including open reduction internal fixation (ORIF), the optimal method for fixation is unclear. ...

Long-term outcomes of the CTAG thoracic endograft in a prospective multicenter trial.

May 24, 2021

The GORE® Conformable TAG® Thoracic Endoprosthesis (CTAG) was engineered to enhance conformability in the thoracic aorta and has demonstrated greater deployment accuracy and wall apposition than the...

Association of the length of time using computers and mobile devices with low back, neck and mid-back pains: findings from a birth cohort.

May 24, 2021

Neck and low back pains are the leading causes of years lived with disability, and using computers or mobile devices in excess could be risk factors for back pain. Our aim was to evaluate the associat...

Finite element modelling and experimental validation of a total implanted shoulder joint.

May 24, 2021

Background Replicating a total shoulder arthroplasty in laboratory is a difficult task due to complex geometry of the structures and degrees of freedom of the joint. Implanted joint shoulders have bee...

Akkermansia muciniphila promotes type H vessels formation and bone fracture healing by reducing gut permeability and inflammation.

May 20, 2021

Improving revascularization is one of the major measures in fracture treatment. Moderate local inflammation triggers angiogenesis, whereas systemic inflammation hampers angiogenesis. Previous studies ...

Uncoiling springs promote mechanical functionality of spider cribellate silk.

May 20, 2021

Composites, both natural and synthetic, achieve novel functionality by combining two or more constituent materials. For example, the earliest adhesive silk in spider webs - cribellate silk - is compos...

In vitro-virtual-reality: an anatomically explicit musculoskeletal simulation powered by in vitro muscle using closed loop tissue-software interaction.

May 20, 2021

Muscle force-length dynamics are governed by intrinsic contractile properties, motor stimulation and mechanical load. Although intrinsic properties are well-characterised, physiologists lack in vitro ...

Walking on chains: the morphology and mechanics behind the fin ray derived limbs of sea-robins.

May 20, 2021

Fish fin rays (lepidotrichia) are typically composed of paired and segmented flexible structures (hemitrichia) that help support and change the shape of the fins to affect water flow. Yet, marine ray-...

Different fuel regulation in two types of myofiber results in different antioxidant strategies in Daurian ground squirrels (Spermophilus dauricus) during hibernation.

May 20, 2021

We previously showed that different skeletal muscles in Daurian ground squirrels (Spermophilus dauricus) possess different antioxidant strategies during hibernation; however, the reason for these vari...

Seismic sensitivity and bone conduction mechanisms enable extratympanic hearing in salamanders.

May 20, 2021

The tympanic middle ear is an adaptive sensory novelty that evolved multiple times in all of the major terrestrial tetrapod groups to overcome the impedance mismatch generated when aerial sound encoun...

Galeazzi fracture-dislocations: Long-term prognosis of the distal radioulnar joint.

May 17, 2021

The aim of the present study was to evaluate long-term functional and radiographic outcome in the distal radioulnar joint (DRUJ) for Galeazzi fracture-dislocation after anatomic reduction and rigid fi...

Characteristics of lumbar flexion rhythm at different arm positions.

May 17, 2021

The lumbar spine displays its greatest mobility in ventral flexion, which is a potential risk factor for low back pain. The relative contribution of each segment to the complete flexion is denoted the...

Delay in Hip Fracture Repair in the Elderly: A Missed Opportunity Towards Achieving Better Outcomes.

May 17, 2021

Hip fractures are a major cause of morbidity and mortality in the elderly. The American Academy of Orthopedic Surgeons (AAOS) recommends surgical repair within 48 hours of admission, as this is associ...

Universal Engraftment after Allogeneic Hematopoietic Cell Transplantation Using Cryopreserved CD34 Selected Grafts.

May 17, 2021

As a result of the COVID-19 pandemic, most centers performing allogeneic hematopoietic cell transplant (allo-HCT) have switched to the use of cryopreserved grafts. Previous investigators have suggeste...

Timing of stress fracture in soldiers during the first 6 career months: a retrospective cohort study.

May 13, 2021

Stress fractures (SF) are injuries that can result from beginning new or higher volume physical training regimens. The pattern of clinical presentation of SF over time after individuals start a new or...
