AUF1 Encourages Expansion and Invasion involving Thyroid gland Most cancers by means of Downregulation regarding ZBTB2 and Future TRIM58.
The question of pregnancy prognosis after radio chemotherapy is unaddressed. We report here the case of three successive spontaneous pregnancies 17 years after the management of a thigh rhabdomyosarcoma treated by radiochemotherapy. In 2018 the patient aged 22 presented with a spontaneous miscarriage. In 2019, she obtained a new spontaneous pregnancy. At 21 W G, she presented with threatened late miscarriage and gave birth to a live girl who would die. Three months after delivery, she had spontaneous pregnancy. At 18 W G, emergency cervical cerclage was performed. At 35 W G the ultrasound found severe intrauterine growth retardation. Cesarean section was performed allowing the birth of a girl in good health status. Childbirth was complicated by 1L8 postpartum hemorrhage secondary to uterine atony, controlled after surgical revision. To conclude, pregnancy in a patient with a history of pelvic irradiation in childhood must be considered high-risk pregnancy and its management must be multidisciplinary.
In 5 % of vaginal deliveries in case of cephalic presentation there is a persistent occipital posterior position known to be associated with a higher maternal and neonatal morbidity. In these situations, vacuum extractor seems to be the best choice for assisted delivery but it also has limits and contraindications, for example an important caput succadenum or premature birth. The aim of our study was to evaluate the rate of intra-pelvic rotation of persistent occipital posterior position without instrumental rotation in case of operative delivery with spatulas.

This is a retrospective, monocentric and descriptive study evaluating the rate of spontaneous intra-pelvic rotation of persistent occipital posterior position in case of assisted delivery with spatulas among all live births at the Besançon University Medical Center between 2010 and 2017.

There were 20 205 births during the study and 81(0,4 %) operative deliveries by spatulas in case of persistent occipital posterior position. Delivery in occiput anterior (OA) position was obtained in 36 cases (44.4 %). There was no significant difference in maternal or neonatal morbidity between both groups and perineum injuries were less severe in case of OA delivery.

Operative deliveries by spatulas without instrumental rotation in case of persistent occipital-posterior position seem to be a relevant alternative to vacuum extractor, especially in case of premature birth or important caput succedaneum without altering the maternal or neonatal prognostic.

Among the hominins, studies that have examined Retzius periodicity (RP) variation have come to contradictory conclusions in some instances. To clarify RP variation among hominins and better place this variation in its broader evolutionary context, we conduct the most comprehensive analysis of published RP values for hominins and great apes to date. We gathered all available data from the literature on RP data from extant humans, great apes, and fossil hominins and assessed their variation using parametric and nonparametric analyses of variance. We also performed phylogenetic generalized least-squares regressions of RP data for these taxa as well as a larger set of hominoids for which RP data have been published against data for body mass, encephalization, and mean semicircular canal radius (a proxy for metabolic rate). Our results show that modern humans have a mean RP significantly differing from that of other hominins. Pongo also is significantly different from nearly all other taxa in all analyses. Our results also demonstrate that RP variation among hominins scales with respect to body mass, encephalization, and semicircular canal radius similarly to other hominids but that modern humans and Pongo stand out in this regard. Operating within the hypothesis that RP reflects autonomic biorhythms that regulate multiple life history variables, our results reinforce the idea that Homo sapiens has evolved a life history distinct from other hominins, even from other members of Homo, and suggest that many of these life history differences may be driven by hypothalamic output from the brain.Considering the versatile functions attributed to uncoupling protein 2 (UCP2) in health and disease, a profound understanding of the protein's molecular actions under physiological and pathophysiological conditions is indispensable. This review aims to revisit and shed light on the fundamental molecular functions of UCP2 in mitochondria, with particular emphasis on its intricate role in regulating mitochondrial calcium (Ca2+) uptake. UCP2's modulating effect on various vital processes in mitochondria makes it a crucial regulator of mitochondrial homeostasis in health and disease.ATP, the universal energy currency in all living cells, is mainly synthesized in mitochondria by oxidative phosphorylation (OXPHOS). The final and rate limiting step of the respiratory chain is cytochrome c oxidase (COX) which represents the regulatory center of OXPHOS. COX is regulated through binding of various effectors to its "supernumerary" subunits, by reversible phosphorylation, and by expression of subunit isoforms. Of particular interest is its feedback inhibition by ATP, the final product of OXPHOS. This "allosteric ATP-inhibition" of phosphorylated and dimeric COX maintains a low and healthy mitochondrial membrane potential (relaxed state), and prevents the formation of ROS (reactive oxygen species) which are known to cause numerous diseases. Excessive work and stress abolish this feedback inhibition of COX by Ca2+-activated dephosphorylation which leads to monomerization and movement of NDUFA4 from complex I to COX with higher rates of COX activity and ATP synthesis (active state) but increased ROS formation and decreased efficiency.Nutrient budgets in semi-arid estuaries, with ephemeral freshwater inflows and limited nutrient sources, are likely incomplete if contributions from submarine groundwater discharge (SGD) are not included. Here, the relative importance of saline/recirculated SGD-derived nutrient fluxes spatiotemporal variability to the overall nutrient budget is quantified for Nueces Bay, Texas, U.S.A., across hydroclimatic conditions ranging from drought to normal, to flood. On average, 67% of the variance in water quality is due to temporal differences while 16% is explained by spatial differences. Principal component analysis (PCA) reveals three principal components freshwater inflow (PC1 28.8%), saline/recirculated SGD and recycled nitrogen (PC2 15.6%), and total SGD and "new" nitrogen (PC3 11.2%). Total SGD porewater fluxes ranged from 29.9-690.3 mmol∙m-2d-1 for ammonium, 0.21-18.7 mmol∙m-2d-1 for nitrite+nitrate, 3.1-51.3 mmol∙m-2d-1 for phosphate, 57.1-719.7 mmol∙m-2d-1 for silicate, and 95.9-36,838.5 mmol∙m-2d-1 for di of shallow groundwater and subsequent contamination of estuaries.
Supracondylar fractures of the humerus are common in children. Whether fixation should be performed with crossed or lateral wires remains controversial. We performed a meta-analysis of randomized controlled trials to evaluate both techniques in terms of the function of the elbow and the risk of neurologic injury and loss of reduction. We also assessed the quality of the evidence currently available.

The MEDLINE, Embase, Cochrane Library, and LILACS (Latin American and Caribbean Health Sciences Literature) databases, as well as ongoing clinical trial databases, were searched until March 2020. The main outcomes were function, measured by the Flynn criteria, and complications (neurologic lesions and loss of reduction). A meta-analysis was conducted using relative risk (RR) analysis for dichotomous variables and difference in means for continuous variables. Heterogeneity was tested using the I
statistic.

Twelve trials, with a total of 930 patients, met the inclusion criteria. Both groups (crossed-wire and lateral-wire fixation) presented satisfactory functional results, with no difference between them (RR, 0.99; 95% confidence interval [CI], 0.96-1.02; P = .44). Patients undergoing crossed-wire fixation had a higher risk of iatrogenic neurologic injury (RR, 0.45; 95% CI, 0.21-0.99; P = .05). The crossed group showed greater fixation stability, with a lower incidence of loss of fracture reduction (RR, 1.39; 95% CI, 1.04-1.85; P = .03). The GRADEpro GDT (Guideline Development Tool) showed that the quality of evidence of the evaluated outcomes was low or very low.

There is evidence of very low quality that fixation with lateral wires is safer regarding iatrogenic nerve lesions whereas fixation with crossed wires is more effective at maintaining fracture reduction.

Axillary artery injury is a devastating complication related to anterior shoulder surgery and can result in significant morbidity and/or mortality. The purpose of our study was to evaluate the course of the axillary artery in relation to bony landmarks of the shoulder and identify variations in artery position with humeral external rotation.

Dissection of 18 shoulders (9 fresh whole-body cadavers) with simulated vessel perfusion using radiopaque dye was performed. The axillary artery position was measured from multiple points including 2 points on the coracoid base (C1 and C2), 3 points on the coracoid tip (C3-C5), 4 points on the glenoid superior, middle, and inferior glenoid (D1-D4), and 2 points on the lesser tuberosity (L1 and L2). INS1007 Fluoroscopic measurements were taken and compared at 0° and 90° of external rotation (F1 vs. F1' and F2 vs. F2'). Manual and fluoroscopic measurements were compared with one another using Kendall's τ
correlation.

There were 6 male and 3 female cadavers with an average als an average of 1-1.8 cm from the inferior glenoid margin, which puts the artery at significant risk. In addition, the artery is significantly closer to the inferior glenoid with humeral external rotation. Surgeons performing anterior shoulder surgery should have a thorough understanding of the axillary artery course and understand changes in the position of the artery with external rotation of the humerus.
