Shedding Light on the Origin of ^{204}Pb, the Heaviest s-Process-Only Isotope in the Solar System.

Asymptotic giant branch stars are responsible for the production of most of the heavy isotopes beyond Sr observed in the solar system. Among them, isotopes shielded from the r-process contribution by their stable isobars are defined as s-only nuclei. For a long time the abundance of ^{204}Pb, the heaviest s-only isotope, has been a topic of debate because state-of-the-art stellar models appeared to systematically underestimate its solar abundance.

Measurement of the ^{140}Ce(n,γ) Cross Section at n_TOF and Its Astrophysical Implications for the Chemical Evolution of the Universe.

^{140}Ce(n,γ) is a key reaction for slow neutron-capture (s-process) nucleosynthesis due to being a bottleneck in the reaction flow. For this reason, it was measured with high accuracy (uncertainty ≈5%) at the n_TOF facility, with an unprecedented combination of a high purity sample and low neutron-sensitivity detectors. The measured Maxwellian averaged cross section is up to 40% higher than previously accepted values.

[Arthroscopic Subtalar Distraction Arthrodesis in Post-Traumatic Indications].

Purpose Of The Study: This manuscript aims to present the method of arthroscopic assisted subtalar arthrodesis and to evaluate the benefi ts of this surgery on our study population.

Material And Methods: In the period from 9/2007 to 1/2020, a total of 33 subtalar arthrodesis were performed in 31 patients aged 19-66 years (mean 48 years, median 50 years). The indication for arthrodesis was subtalar arthritis causing pain and gait disorders, or hindfoot deformities (most commonly after a calcaneus bone fracture).

Risk factors predicting cervical spine fracture on CT in craniocervical trauma - retrospective study.

Introduction: The study identifies risk factors predicting cervical spine fracture on CT based on information in the referral form.

Methods: All patients aged over 18 years with a CT scan of the head and cervical spine completed at the University Hospital Brno in the year 2019 to exclude any fresh trauma were included in the retrospective study. The analyzed potential risk factors included gender, age over 65 years, unconsciousness or impaired consciousness, mechanism of injury, paresthesia or plegia suspected to be associated with trauma, cervical spine pain, other neurological symptomatology, presence of cervical collar, presence of intracranial hemorrhage on head CT, and presence of skull fracture on head CT.

Ge( ) cross section below 70 keV measured at n_TOF CERN.

Neutron capture reaction cross sections on Ge are of importance to determine Ge production during the astrophysical slow neutron capture process. We present new resonance data on Ge( ) reactions below 70 keV neutron energy. We calculate Maxwellian averaged cross sections, combining our data below 70 keV with evaluated cross sections at higher neutron energies.

Automatic 3D analysis of the ex-vivo porcine lumbar interbody fusion based on X-ray micro computed tomography data.

Spinal fusion is a surgical procedure used to join two or more vertebrae to prevent movement between them. This surgical procedure is considered in patients suffering from a wide range of degenerative spinal diseases or vertebral fractures. The success rate of spinal fusion is frequently evaluated subjectively using X-ray computed tomography.

Lumbar Interbody Fusion Conducted on a Porcine Model with a Bioresorbable Ceramic/Biopolymer Hybrid Implant Enriched with Hyperstable Fibroblast Growth Factor 2.

Many growth factors have been studied as additives accelerating lumbar fusion rates in different animal models. However, their low hydrolytic and thermal stability both in vitro and in vivo limits their workability and use. In the proposed work, a stabilized vasculogenic and prohealing fibroblast growth factor-2 (FGF2-STAB) exhibiting a functional half-life in vitro at 37 °C more than 20 days was applied for lumbar fusion in combination with a bioresorbable scaffold on porcine models.

Ex-vivo biomechanical testing of pig femur diaphysis B type fracture fixed by novel biodegradable bone glue.

Aims: The aim of this study was to answer the question whether our newly developed injectable biodegradable "self-setting" polymer-composite as a bone adhesive is a good "bone-glue" candidate to efficiently fix comminuted fractures of pig femoral bones used as an ex-vivo experimental model.

Methods: Mechanical properties of adhesive prepared from α-tricalcium phosphate (TCP) powder and thermogelling copolymer were optimized by selecting the appropriate composition with adhesion enhancers based on dopamine and sodium iodinate. Setting time and injectability were controlled by rheology.

Neutron Capture on the s-Process Branching Point ^{171}Tm via Time-of-Flight and Activation.

The neutron capture cross sections of several unstable nuclides acting as branching points in the s process are crucial for stellar nucleosynthesis studies. The unstable ^{171}Tm (t_{1/2}=1.92  yr) is part of the branching around mass A∼170 but its neutron capture cross section as a function of the neutron energy is not known to date.

Rare Mucor circinelloides and Fusarium infection in latissimus free flap reconstruction after devastating foot injury in non-neutropenic patient.

Nowadays, free flap reconstruction in devastating lower limb trauma is a standard procedure in reconstructive surgery. The greatest factor directly affecting limb salvage is still the risk of infectious complications, whether local or systemic. Fungal wound infections are not among the most common infection complications in surgery, but their low incidence is compensated for by their fulminant and serious course, as well as severe local tissue destruction and strong angio-invasive potential together with the possibility of dissemination.

[Importance of Skull X-ray in Head Trauma].

PURPOSE OF THE STUDY The aim of our study is to show the pitfalls of performing skull X-rays in patients with head injuries and the lack of accuracy of this examination nowadays, and to clarify the current trend in the MTBI investigation algorithm. MATERIAL AND METHODS A retrospective study of 3,950 patients treated for acute head injury at the Department of Trauma Surgery (University Hospital Brno) in the period from 2015 to 2016. Inclusion criteria were the following: mild brain injury (GCS = 15), primary skull X-ray design in head injury diagnosis.

[Ipsilateral Fractures of the Coracoid and Acromion Process of the Scapula Combined with the Distal Clavicle End Fracture, Treatment Options].

Superior Shoulder Suspensory Complex (SSSC) is a bone and soft-tissue ring securing the connection of the upper extremity to the axial skeleton via the clavicle and sternoclavicular joint. An isolated injury to one component of SSSC is usually stable. An injury to 2 of its components is a potential source of shoulder girdle instability and requires surgical stabilisation.

The Effect of the Thermosensitive Biodegradable PLGA⁻PEG⁻PLGA Copolymer on the Rheological, Structural and Mechanical Properties of Thixotropic Self-Hardening Tricalcium Phosphate Cement.

The current limitations of calcium phosphate cements (CPCs) used in the field of bone regeneration consist of their brittleness, low injectability, disintegration in body fluids and low biodegradability. Moreover, no method is currently available to measure the setting time of CPCs in correlation with the evolution of the setting reaction. The study proposes that it is possible to improve and tune the properties of CPCs via the addition of a thermosensitive, biodegradable, thixotropic copolymer based on poly(lactic acid), poly(glycolic acid) and poly(ethylene glycol) (PLGA⁻PEG⁻PLGA) which undergoes gelation under physiological conditions.

A Comparative Study of Conservative Functional Treatment versus Acute Ligamentous Repair in Simple Dislocation of the Elbow in Adults.

Background: Elbow dislocation is the second most frequent type of large joint dislocations in adults. Standard treatment of simple elbow dislocation (SED) without manifestation of instability includes closed reduction, short-term immobilization of the elbow followed by functional aftercare. This study evaluates SED treatment, comparing outcomes of conservative functional treatment and surgical therapy.

^{7}Be(n,p)^{7}Li Reaction and the Cosmological Lithium Problem: Measurement of the Cross Section in a Wide Energy Range at n_TOF at CERN.

We report on the measurement of the ^{7}Be(n,p)^{7}Li cross section from thermal to approximately 325 keV neutron energy, performed in the high-flux experimental area (EAR2) of the n_TOF facility at CERN. This reaction plays a key role in the lithium yield of the big bang nucleosynthesis (BBN) for standard cosmology. The only two previous time-of-flight measurements performed on this reaction did not cover the energy window of interest for BBN, and they showed a large discrepancy between each other.

[Remission of steroid-resistant Stills disease treated with anakinra, evidenced by FDG-PET/CT examination: case report].

After elimination of infectious causes, neoplastic causes and the systemic autoimmune disease of connective tissue, a patient with high fevers over 39 °C was diagnosed with Stills disease. High doses of prednisone led to resolution of symptoms, however after reducing the doses of prednisone to 15 mg, high fevers over 39 °C returned, as well as joint pains. The high doses of prednisone led to decompensation of diabetes mellitus even with 4 daily insulin dosages.

Fasciotomy closure using negative pressure wound therapy in lower leg compartment syndrome.

Background: Fasciotomy wounds can be a major contributor to length of stay for patients as well as a difficult reconstructive challenge.

Objectives: To evaluate lower leg fasciotomy wound closure outcomes comparing treatment with combined dressing fabric (COM) and negative pressure wound therapy (NPWT) in combination with elastic dynamic ligature (EDL).

Methods: Retrospective study of 63 patients who underwent lower leg fasciotomy due to injury treated from January 2008 to December 2015 at the Department of Trauma Surgery, University Hospital Brno.

^{7}Be(n,α)^{4}He Reaction and the Cosmological Lithium Problem: Measurement of the Cross Section in a Wide Energy Range at n_TOF at CERN.

The energy-dependent cross section of the ^{7}Be(n,α)^{4}He reaction, of interest for the so-called cosmological lithium problem in big bang nucleosynthesis, has been measured for the first time from 10 meV to 10 keV neutron energy. The challenges posed by the short half-life of ^{7}Be and by the low reaction cross section have been overcome at n_TOF thanks to an unprecedented combination of the extremely high luminosity and good resolution of the neutron beam in the new experimental area (EAR2) of the n_TOF facility at CERN, the availability of a sufficient amount of chemically pure ^{7}Be, and a specifically designed experimental setup. Coincidences between the two alpha particles have been recorded in two Si-^{7}Be-Si arrays placed directly in the neutron beam.

[Isolated Displaced Fracture of the Acromion - Case Report].

Unlabelled: Displaced fractures of the acromion are rare injuries. A 45-year-old lady presented with an isolated acromion fracture (type III, Kuhn classification) resulting from a direct blow to the top of her right shoulder in a fall while skiing. After standard clinical and radiological examination of the shoulder, an open reduction and internal plate fixation using a postero-superior approach to the scapula was performed.

[Effect of Negative Pressure Wound Therapy on Infectious Complications in Grade III Open Fractures].

Unlabelled: PURPOSE OF THE STUDY Grade III open fractures are associated with infectious complications in 25-66% of injuries. Negative pressure wound therapy (NPWT) applied to an injured soft tissue coverage provides an impermeable barrier between the injured structures and the external environment, in addition to early secretion draining and a positive effect on the site of application. All this also prevents secondary bacterial contamination.

Neutron capture cross section of unstable 63Ni: implications for stellar nucleosynthesis.

The 63Ni(n,γ) cross section has been measured for the first time at the neutron time-of-flight facility n_TOF at CERN from thermal neutron energies up to 200 keV. In total, capture kernels of 12 (new) resonances were determined. Maxwellian averaged cross sections were calculated for thermal energies from   kT=5-100  keV with uncertainties around 20%.

Low-energy enhancement in the photon strength of 95Mo.

A new experimental technique is presented using proton-γ-γ correlations from (94)Mo(d,p)(95)Mo reactions which allows for the model-independent extraction of the photon strength function at various excitation energies using primary γ-ray decay from the quasicontinuum to individual low-lying levels. Detected particle energies provide the entrance excitation energies into the residual nucleus while γ-ray transitions from low-lying levels specify the discrete states being fed. Results strongly support the existence of the previously reported low-energy enhancement in the photon strength function.

Traumatic haemarthrosis of the knee -- indication to acute arthroscopy.

Background And Aims: The most common mechanisms of the knee injuries are distortions and contusions. Fairly often they will result in hemarthrosis. The purpose of this study was to evaluate the findings in patients with acute traumatic hemarthrosis of the knee and based on these findings estimate the necessity of acute artroscopic examination with therapeutic procedure.

[Early suture versus ligamentoplasty of scapholunate ligament injury: comparison of clinical results].

Purpose Of The Study: The aim was to evaluate subjective and objective criteria of wrist, hand and arm function in a group of patients with acute static scapholunate dissociation treated by acute suture or ligament reinsertion, and in a group of patients with chronic static scapholunate dissociation treated by ligament reconstruction using ligamentoplasty.
