These findings support therapeutic strategies that modulate VISTA expression, perhaps in combination with PD-1/PD-L1 blockade, in human breast cancer immunotherapy.This study aimed to assess modulation of lower leg muscle reflex excitability and co-contraction during unipedal balancing on compliant surfaces in young and older adults. Twenty healthy adults (ten aged 18-30 years and ten aged 65-80 years) were recruited. Soleus muscle H-reflexes were elicited by electrical stimulation of the tibial nerve, while participants stood unipedally on a robot-controlled balance platform, simulating different levels of surface compliance. In addition, electromyographic data (EMG) of soleus (SOL), tibialis anterior (TA), and peroneus longus (PL) and full-body 3D kinematic data were collected. The mean absolute center of mass velocity was determined as a measure of balance performance. Soleus H-reflex data were analyzed in terms of the amplitude related to the M wave and the background EMG activity 100 ms prior to the stimulation. The relative duration of co-contraction was calculated for soleus and tibialis anterior, as well as for peroneus longus and tibialis anterior. Center of mass velocity was significantly higher in older adults compared to young adults ([Formula see text] and increased with increasing surface compliance in both groups ([Formula see text]. The soleus H-reflex gain decreased with surface compliance in young adults [Formula see text], while co-contraction increased [Formula see text]. Older adults did not show such modulations, but showed overall lower H-reflex gains [Formula see text] and higher co-contraction than young adults [Formula see text]. These results suggest an overall shift in balance control from the spinal level to supraspinal levels in older adults, which also occurred in young adults when balancing at more compliant surfaces.Single-pulse transcranial magnetic stimulation (spTMS) studies report that movement observation facilitates corticospinal excitability in primary motor cortex (M1) in a muscle-specific manner. However, motor evoked potentials (MEPs) elicited by spTMS are known to reflect the summation of several descending volleys in corticospinal neurons which are evoked via mono- and polysynaptic inputs (so-called indirect waves or I-waves). It is unclear which of these components contribute to the muscle-specific modulation of M1 during action observation. The interactions between different I-waves are reflected in the facilitatory peaks elicited with a short-intracortical facilitation (SICF) protocol when two pulses are sent to M1 at precise intervals (i.e., 1.3, 2.5 or 4.1 ms). Here, we explored the modulation of early and late SICF peaks during action observation by measuring highly specific MEP amplitude changes measured in two muscles (index, FDI and little finger, ADM) while participants observed two different actions (precision and whole-hand grip). Our results demonstrate that both early (1.3 ms) and late (2.5 and 4.1 ms) SICF peaks are modulated in the context of movement observation. However, only the second peak (ISI 2.5 ms) was significantly associated with the muscle-specific modulation of corticospinal excitability as measured with spTMS. This late SICF peak is believed to reflect the activity cortico-cortical pathways involved in the facilitation of muscle-specific representations in M1. Thus, our findings suggest that movement observation leads to widespread activation of different neural circuits within M1, including those mediating cortico-cortical communication.Ovarian torsion is a gynecological emergency that leads to serious outcomes. Nicorandil (NIC) is an ATP-sensitive potassium (KATP) channel activator that protects the heart from ischemia. The current study aimed to investigate the role and mechanism of action of NIC in ovarian ischemia-reperfusion (OIR) and possible KATP participation. Twenty-four female albino rats were classified into 4 groups sham control, OIR, OIR + NIC, OIR + NIC+ glibenclamide (GLB) groups. Serum anti-Müllerian hormone (AMH), ovarian malondialdehyde (MDA), total nitrites (NOx) contents, and superoxide dismutase (SOD) activity were evaluated. find more Bax and Bcl2 mRNA were also assessed. Histological and immunohistochemical (anti-COX-2 and anti CD68) studies were done. The OIR non-treated group showed histopathological ovarian injury with decreased AMH level. Ovarian MDA, NOx, and Bax mRNA and the expression of COX-2 and CD68 were increased; however, SOD activity and Bcl2 mRNA level were decreased by OIR. NIC significantly ameliorated the histopathological ovarian injury with the restoration of AMH level. NIC significantly corrected oxidative stress and apoptotic biomarkers with decreased COX-2 and CD68 immunostaining. GLB co-administration significantly decreased the protection afforded by NIC. These results imply that NIC has a protective role against OIR via antioxidant, anti-inflammatory, and anti-apoptotic effects and such protection relies, at least partially, on the KATP channel.Pulmonary agenesis is a rare developmental defect in which there is complete absence of one or both lungs. Although the diagnosis is often made during childhood, asymptomatic patients can be diagnosed later due to the absence of comorbid anomalies. Chest radiography with an elevation of the hemidiaphragm and heart shifted to the right should make physicians suspicious for right lung agenesis. Here, we present a case report of a 53-year-old male with unilateral pulmonary agenesis of right lung found incidentally. He had a complaint of dyspnea. The respiratory system examination revealed no breathing sounds on the right side with normal breathing sounds on the left side. A posterior anterior chest radiograph revealed homogenous opacity of the middle and lower radiological lung zone with elevation of the right hemidiaphragm. In addition, the trachea and heart were shifted to the right side. Contrast-enhanced multidetector computed tomography revealed the absence of the right lung parenchyma, right main bronchus, and right main pulmonary artery and vein. The left lung had normal pulmonary vasculature, was hyperinflated, and partially extended to the right hemithorax. A pulmonary conus was formed by only the left pulmonary artery. No congenital anomalies were detected.PURPOSE Brain expansion during ontogeny has been identified as a key factor for explaining the growth pattern of neurocranial bones. However, the dynamics of this relation are only partially understood and a detailed characterization of integrated morphological changes of the brain and the neurocranium along ontogeny is still lacking. The aim of this study was to model the effect of brain growth on cranial bones by means of finite-element analysis (FEA) and geometric morphometric techniques. METHODS First, we described the postnatal changes in brain size and shape by digitizing coordinates of 3D semilandmarks on cranial endocasts, as a proxy of brain, segmented from CT-scans of an ontogenetic sample. Then, two scenarios of brain growth were simulated one in which brain volume increases with the same magnitude in all directions, and other that includes the information on the relative expansion of brain regions obtained from morphometric analysis. RESULTS Results indicate that in the first model, in which a uniform pressure is applied, the largest displacements were localized in the sutures, especially in the anterior and posterior fontanels, as well as the metopic suture. When information of brain relative growth was introduced into the model, displacements were also concentrated in the lambda region although the values along both sides of the neurocranium (parietal and temporal bones) were larger than under the first scenario. CONCLUSION In sum, we propose a realistic approach to the use of FEA based on morphometric data that offered different results to more simplified models.All large population-based administrative studies currently indicate a significant comorbidity of adult attention deficit hyperactivity disorder (ADHD) with addictive, anxiety and in particular affective disorders. In these investigations the risk for one of these comorbid disorders increased with increasing age of the ADHD patients. The most recent genome-wide association and correlation studies also revealed indications for joint genetic risk factors of ADHD with, in particular unipolar depression, bipolar disorder, autism spectrum disorders, Tourette's syndrome and to a lesser extent schizophrenia. The only psychiatric disorder that was negatively correlated with ADHD was anorexia nervosa. Additionally, cannabis and cocaine use were significantly positively genetically correlated with ADHD. Furthermore, an increased occurrence of some specific somatic diseases could be found in patients with adult ADHD. In particular, obesity, migraine, sleep disorders, asthma and celiac disease showed a significantly positive association with ADHD in several studies. No association was found between ADHD and cardiovascular disease. Here as well there are initial indications of joint genetic risk variants; however, data are still sparse and additional studies are needed before valid conclusions can be drawn. To some extent these associated somatic diseases might be differential diagnoses rather than true comorbidities, for example, obstructive sleep apnea syndrome (OSAS) can lead to ADHD-like symptoms that disappear when the OSAS is sufficiently treated. Therefore, it is important to keep the co-occurrence of psychiatric and somatic disorders in mind during the diagnostics and treatment of adult ADHD patients to improve their general health and quality of life.PURPOSE To understand whether two different designs of Haas-type rapid maxillary expander (H‑RME) might have a different influence on canine eruption. PATIENTS AND METHODS In all, 108 subjects seeking orthodontic treatment were selected and divided into two groups-H‑RME with bands on the upper second deciduous molars (GrE), H‑RME with bands on the upper first permanent molars (Gr6)-and were also compared to an historical untreated control group (CG) of 29 subjects. Panoramic x‑rays (OPG) were performed before and after RME (T0-T1 16 ± 7 months) and the upper canine angulation to the midline ("α" angle) was measured on both pre- and posttreatment OPG. RESULTS A significant improvement of the canine position (decrease of the α angle) following RME in subjects with mixed dentition was reported in both treated groups, although the different design of the RME did not significantly affect canine angulation. Canine angulation in untreated subjects with transversal discrepancy did not improve significantly. CONCLUSION Using RME in the early mixed dentition appears to be an effective procedure to increase the rate of eruption of maxillary canines, but the position of the bands on the upper second deciduous molars or on the upper first permanent molars and the significant different expansion of the upper dental arch at the canine level does not significantly influence the canine angulation following early treatment therapy.The International Osteoporosis Foundation (IOF) Capture the Fracture® Campaign with the Fragility Fracture Network (FFN) and National Osteoporosis Foundation (NOF) has developed eleven patient-level key performance indicators (KPIs) for fracture liaison services (FLSs) to guide quality improvement. INTRODUCTION Fracture Liaison Services (FLSs) are recommended worldwide to reduce fracture risk after a sentinel fracture. Given not every FLS is automatically effective, the IOF Capture the Fracture working group has developed and implemented the Best Practice Framework to assess the organisational components of an FLS. We have now developed a complimentary KPI set that extends this assessment of performance to the patient level. METHODS The Capture the Fracture working group in collaboration with the Fragility Fracture Network Secondary Fragility Fracture Special Interest Group and National Osteoporosis Foundation adapted existing metrics from the UK-based Fracture Liaison Service Database Audit to develop a patient-level KPI set for FLSs.
