Cubital tunnel syndrome (CubTS) is one of the most common compression-traction neuropathy in the upper extremity. The gold standard is simple in situ decompression with revision of potential compression sites through skin incision as small as rationally possible. Properly conducted conservative treatment is more effective in CubTS as opposed to carpal tunnel syndrome. At the same time, optimal management of CubTS remains controversial. Nevertheless, there is a subclass of patients with symptoms of CubTS that have ulnar nerve instability (UNI) with subluxation of the nerve over the medial epicondyle where conservative treatment would not be successful. UNI can be diagnosed by ultrasound preoperatively, but there are situations where the ulnar nerve becomes unstable with elbow flexion already on the operating table. Currently the most popular surgical reconstruction for clinically relevant UNI is anterior transposition of the nerve. With the proposed technique the nerve stays in orthotopic position, and the segmental vascularity is preserved, innervation to the flexor carpi ulnaris muscle is not jeopardized and ulnar nerve glide-floss exercises are possible as opposed to the standard subcutaneous transposition technique. No subfascial transposition, slings or blocking flaps are used for nerve stabilization which we consider contradiction to the surgery of nerve release.
Some studies have shown that it is possible to evaluate tubal permeability through MRI. Our aim is to perform a prospective study and to perform a comprehensive review in the literature regarding HSG-MRI.

We carried out a PUBMED search using the following keywords hysterosalpingogram, hysterosalpingography, magnetic resonance imaging and MRI. As inclusion criteria, we included only papers published in English, and exams ran on humans. We also conducted a prospective inclusion of patients who had visited a human reproduction clinic between May/2017 and April/2019 for laboratory image diagnoses using HSG-MRI.

Following the inclusion and exclusion criteria, we included seven original papers. Review papers and those written in a language other than English, were excluded. Between the period of May/2017 and April/2019, we selected ten patients for our study. The average exam duration was 30 minutes. Cervical catheterization was possible in all cases. There were no major complications. We highlight that in 8/9 of patients, we could directly visualize uterine tubes with contrast (excluding one patient with bilateral tubal ligation).

Our initial experience with HSG-MRI shows promise. We demonstrated an optimized protocol for conducting an HSG-MRI (with excellent image quality). HSG-MRI had some advantages, such as not using ionized radiation, less pain and being able to analyze pelvic anatomy. Patients referred for a pelvic MRI as part of a more detailed investigation into infertility can also benefit from undergoing a simultaneous HSG using MRI.

TEI refers to the changes in chromatin state, gene expression, and/or phenotypes that are transmitted across several generations without involving changes to the DNA sequences. TEI has direct connections with, and feeds from, the fields of molecular biology, genetics, developmental biology, and reproductive biology, among others. However, the expansion of TEI-related research, has profoundly reshaped boundaries within each field and often led to the erosion of theories and concepts considered as tenets of biology. We first explore how the molecularization of biology has shifted the definition of epigenetics to include the notion of heredity and how epigenetics has refined our understanding of the central dogma of biology. The demonstrated transfer of environmental information from soma to germ cell through extracellular vesicles and subsequent alteration of health outcomes in offspring has put a definite end to the long-held principle of the Weismann barrier. TEI has also simultaneously led to the revival of the inheritance of acquired characteristics while further eroding the concept of an epigenetic "blank slate" in mammals. Using an historical framework, and via the exploration of central studies in the field, in this perspective article, we will draw a compelling argument for the revolutionary aspect of TEI in biology.In this work, novel types of nitrogen-doped carbon dots (N-CDs) were prepared from citric acid and glycine (GLY) as precursors through a simple pyrolysis method. The GLY-CDs showed strong fluorescence with a fluorescence quantum yield as high as 33.34% and good water solubility. The fluorescence of GLY-CDs could be selectively quenched by iron(III) ion (Fe3+ ) resulting in the non-fluorescent complex. Due to the high affinity of Fe3+ to adenosine-5'-triphosphate (ATP), the fluorescence of the GLY-CDs in GLY-CDs-Fe3+ could be recovered by ATP. Thereby, quantitatively fluorescent turn-on detection of ATP could be achieved. The fluorescence recovery ratio was linearly proportional to the concentration of ATP with a detection limit as low as 15.0 nM, indicating the CDs have high sensitivity. The GLY-CDs were successfully employed in the detection of ATP in serum and cell lysates.Elucidating the chromatin dynamics that orchestrate embryogenesis is a fundamental question in developmental biology. Here, we exploit position effects on expression as an indicator of chromatin activity and infer the chromatin activity landscape in every lineaged cell during Caenorhabditis elegans early embryogenesis. Systems-level analyses reveal that chromatin activity distinguishes cellular states and correlates with fate patterning in the early embryos. As cell lineage unfolds, chromatin activity diversifies in a lineage-dependent manner, with switch-like changes accompanying anterior-posterior fate asymmetry and characteristic landscapes being established in different cell lineages. Upon tissue differentiation, cellular chromatin from distinct lineages converges according to tissue types but retains stable memories of lineage history, contributing to intra-tissue cell heterogeneity. However, the chromatin landscapes of cells organized in a left-right symmetric pattern are predetermined to be analogous in early progenitors so as to pre-set equivalent states. Finally, genome-wide analysis identifies many regions exhibiting concordant chromatin activity changes that mediate the co-regulation of functionally related genes during differentiation. Collectively, our study reveals the developmental and genomic dynamics of chromatin activity at the single-cell level.
Substance P (SP) and toll-like receptors (TLRs) contribute to airway disease, particularly during viral infection. We recently demonstrated that SP can act as an initial response to viral stimuli in the upper airway by upregulating TLRs in the nasal epithelia (the SP-TLR axis). KRas(G12C)inhibitor9 Patients with allergic rhinitis (AR) suffer from prolonged airway infections. The aim of the present study was to examine if patients with AR exhibit a disturbance in the SP-TLR axis.

Human nasal biopsies and human nasal epithelial cells (HNEC) from healthy volunteers and patients with AR were cultured in the presence of SP. Epithelial expression of TLR4, neutral endopeptidase (NEP) and neurokinin 1 (NK1) were evaluated with flow cytometry and/or quantitative polymerase chain reaction after 30min to 24h. The effect of SP on nasal lipopolysaccharide-induced interleukin-8 (IL-8) release was investigated.

SP stimulation of tissue from healthy volunteers resulted in a transient increase of the TLR4 expression, whereas stimulation of AR patient-derived material led to a delayed and prolonged upregulation of TLR4. NEP expression in HNEC was lower in AR than healthy controls whereas NK1 receptor expression was increased. SP pretreatment increased TLR4-dependent IL-8 expression in healthy controls, but not in AR.

SP-induced regulation of TLR4 in the human nasal mucosa is disturbed in AR. An altered SP-mediated innate immune response may contribute to the dysfunctional and often prolonged responses to infection in AR.

This resulted in a significant limitation of SCIT use and in the search of other routes of administration, among which sublingual immunotherapy (SLIT) showed the best balance between efficacy and safety. Data from controlled studies suggest that tablets-related anaphylaxis is an uncommon event. However, in the Eudravigilance (European database of suspected adverse drug reactions from Europe) we found reports of life-threatening events or severe local reactions under SLIT increasing over the last few years. Therefore, all efforts to minimize the related risk have to be strongly encouraged.
The MEGA (MEchanism underlying the Genesis and evolution of Asthma) project is a multicenter cohort study carried out in eight Spanish hospitals, gathering clinical, physiological, and molecular data from patients with asthma and multimorbidities in order to gain insight into the different physiopathological mechanisms involved in this disorder.

We report the baseline clinical and physiological characteristics and biomarker measures of adult participants in the project with the aim of better understanding the natural history and underlying mechanisms of asthma as well as the associated multimorbidities across different levels of severity. We carried out a detailed clinical examination, pulmonary function testing, measurement of fractional exhaled nitric oxide (FeNO), blood counts, induced sputum, skin prick tests, chest computed tomography scan, asthma questionnaires, and multimorbidity assessment in 512 asthmatic patients.

When compared to patients with milder disease, severe asthmatic patients showed greater presence of symptoms, more exacerbations, lower asthma control, increased airflow obstruction, and higher frequency of chronic rhinosinusitis with nasal polyps, severe rhinitis, anxiety and depression, gastroesophageal reflux, and bronchiectasis.

The MEGA project succeeded in recruiting a high number of asthma patients, especially those with severe disease, who showed lower control and higher frequency of multimorbidities.
