The structure of the reflexive subject represents the basis of a sociotype that can be considered as the third component of biosocial being in addition to genotype and phenotype; it is defined a social form of the individual bonded by the social environment and social interactions. The transition to a different type of social relations and structure is based on an anticipated reflexive choice by an individual that is accompanied by a coherent response from the society. This change is defined as a "social transaction" and can be modeled by the logic of the transactional interpretation of quantum mechanics. In the history of human civilization, social transactions have resulted in the advancement and distribution of new knowledge and technologies, and in the formation, merging, splitting and decline and re-emergence of particular types of societies.
High antimicrobial use (AMU) and antimicrobial resistance (AMR) in veal calves remain a source of concern. As part of the EFFORT project, the association between AMU and the abundance of faecal antimicrobial resistance genes (ARGs) in veal calves in three European countries was determined.
In 2015, faecal samples of veal calves close to slaughter were collected from farms located in France, Germany and the Netherlands (20 farms in France, 20 farms in the Netherlands and 21 farms in Germany; 25 calves per farm). Standardized questionnaires were used to record AMU and farm characteristics. In total, 405 faecal samples were selected for DNA extraction and quantitative polymerase chain reaction to quantify the abundance (16S normalized concentration) of four ARGs [aph(3')-III, ermB, sul2 and tetW] encoding for resistance to frequently used antimicrobials in veal calves. Multiple linear mixed models with random effects for country and farm were used to relate ARGs to AMU and farm characteristics.

Cases of primary central nervous system lymphoma manifesting with hemorrhage are very rare, with only a few previous studies available.
A 49-year-old man presented with occipital headache and visual disturbance for the past 4 months. Computed tomography showed a high-density area involving the left basal ganglia, with surrounding vasogenic edema. Head T2∗-weighted imaging showed a hypointense signaling area. Edematous changes and a midline shift were observed on fluid attenuated inversion recovery magnetic resonance imaging. Radiologic features were highly suggestive of intracerebral hemorrhage. Methylprednisolone pulse therapy improved his symptoms transiently and reduced the size of the lesion. Nonetheless, there was recurrence 1 month later. The patient was referred to our institution; a biopsy was performed, and a diffuse large B-cell lymphoma was diagnosed. After 3 cycles of high-dose methotrexate and whole-brain radiation therapy, his symptoms improved, and there were no signs of recurrence.
We report a very rare case of diffuse large B-cell lymphoma manifested with intratumoral hemorrhage. see more This case indicates the importance of regular clinical and radiologic follow-up, histopathologic examination, and combined treatment with high-dose methotrexate and whole-brain radiation therapy.

Primary intracranial sarcomas of the central nervous system are rare tumors. They mainly arise from intracranial mesenchymal tissue present in the meninges and can occur at any age. Sometimes osteosarcoma can involve the skull rather than long body bones. In this latter case it is the more common subtype. Surgery, when possible, is a mandatory option often associated with radiation therapy (RT) and chemotherapy. Brain radionecrosis (BRN) is commonly observed due to the growing use of radiosurgery and higher cumulative doses of radiation therapy. The combination of perfusion magnetic resonance imaging and
fluoro-deoxy-glucose positron emission tomography can help to differentiate tumor progression from radiation injury. Steroids, anticoagulants, and bevacizumab usually control BRN. However, BRN can also have an unfavorable course.
Here, we present a case of a 60-year-old male who underwent surgery for a brain tumor. The examination showed a primary undifferentiated high-grade sarcoma. Adjuvant RT was givg to its potential severe neurologic toxicity. Indeed, a BRN can have a significant impact on quality of life and lead to death in certain cases.
Craniocervical junction (CCJ) dislocations are often fatal. Atlanto-occipital dissociation can be challenging to diagnose, especially in patients who present with absent or subtle radiologic signs.
A neurologically intact 37-year-old patient presented to the hospital following a high-speed motor vehicle accident. Initial computed tomography scans showed normal CCJ anatomy, but magnetic resonance imaging (MRI) of the CCJ was performed to further evaluate perimesencephalic subarachnoid hemorrhage. MRI revealed partial disruption of the anterior atlantoaxial membrane and tectorial membrane as well as complete disruption of the posterior atlanto-occipital membrane, ligamentum flavum, and apical ligament, signifying atlanto-occipital dissociation. Halo spinal immobilization was performed in preparation for stabilization with posterior occipitocervical fusion; however, the CCJ distracted widely during surgery owing to the accident-related dislocation, signifying an unstable fracture. Posterolateral fusion was pbarachnoid hemorrhage after a blunt injury with neck pain. When MRI shows evidence of disruption of ≥2 atlanto-occipital ligaments, surgical stabilization should be considered, as these are clinically very unstable injuries.
To assess the surface roughness and residual flaws in two translucent zirconia substrates following simulated clinical adjustment and intra-oral finishing/polishing.
Specimens were prepared from two translucent (5Y-ZP/8Y-ZP) and one conventional (3Y-TZP) zirconia substrates (n = 84 p/g). Arithmetic mean roughness parameter (R
) was determined for all experimental groups at four stages (n = 21 p/g) (1) as-sintered, (2) surface grinding using a zirconia cutting diamond bur, (3) polishing using 1-step, 2-step or 4-step intra-oral polishing kits, and (4) laboratory polishing/glazing. Scanning electron microscopy (SEM) was used to evaluate residual surface flaws. Data were statistically analysed using a two-way ANOVA test, multiple and pairwise comparisons were performed using a Bonferroni post hoc test.
R
was significantly higher for as-sintered and ground 5Y-ZP/8Y-ZP compared to 3Y-TZP (p ≤ 0.001). Material type and polishing protocol had statistically significant effect on R
(p < 0.001). The 4-step polishing resulted in the lowest R
in 3Y-TZP/5Y-ZP (p ≤ 0.
