A New Species of Palarus Latreille from Spain with a Comparative Study on Nesting Behavior and Larvae in the Genus (Hymenoptera: Sphecidae)
1992
Palarus almerienis n. sp. is described from Spain (including imago, larva, and nesting habits). P. confusus Turner, currently considered a subspecies of P. ambustus Klug, is raised to full species status. The most important differences among the three species involve sculpture of the mesopleuron. The geographical distribution of these three taxa is discussed. Females of P. almeriensis excavate unicellular nests and capture not only Hymenoptera (the usual prey of the genus), but also Diptera (Stratiomyiidae). They make temporary closures and store the prey in the gallery before transferring it to the cell, which they dig during provisioning. Several species of Diptera (Miltogramminae) are na…
Species-specific genes under selection characterize the co-evolution of slavemaker and host lifestyles.
2017
Background The transition to a parasitic lifestyle entails comprehensive changes to the selective regime. In parasites, genes encoding for traits that facilitate host detection, exploitation and transmission should be under selection. Slavemaking ants are social parasites that exploit the altruistic behaviour of their hosts by stealing heterospecific host brood during raids, which afterwards serve as slaves in slavemaker nests. Here we search for evidence of selection in the transcriptomes of three slavemaker species and three closely related hosts. We expected selection on genes underlying recognition and raiding or defense behaviour. Analyses of selective forces in species with a slavemak…
Effect of Intraoperative High Positive End-Expiratory Pressure (PEEP) with Recruitment Maneuvers vs Low PEEP on Postoperative Pulmonary Complications…
2019
Importance: An intraoperative higher level of positive end-expiratory positive pressure (PEEP) with alveolar recruitment maneuvers improves respiratory function in obese patients undergoing surgery, but the effect on clinical outcomes is uncertain. Objective: To determine whether a higher level of PEEP with alveolar recruitment maneuvers decreases postoperative pulmonary complications in obese patients undergoing surgery compared with a lower level of PEEP. Design, Setting, and Participants: Randomized clinical trial of 2013 adults with body mass indices of 35 or greater and substantial risk for postoperative pulmonary complications who were undergoing noncardiac, nonneurological surgery un…
Ultrasonography of the Lung.
2019
High diagnostic accuracy, increasing clinical experience and technical improvements are good reasons to consider lung ultrasound (US) for the assessment of pleural and pulmonary diseases. In the emergency room and in intensive care, it is well acknowledged, but application in other settings is rare. The aim of this review is to update potential users in general radiology about the diagnostic scope of lung US and to encourage more frequent use of this generally underestimated lung imaging modality. Literature review was done independently by the two authors in MEDLINE (via PubMed) covering a time span from 2002 until 2017 using free text and Medical Subject Headings/MeSH. Article selection …
Diagnosis, assessment, and management of surgical complications following esophagectomy
2018
Despite improvements in operative strategies for esophageal resection, anastomotic leaks, fistula, postoperative pulmonary complications, and chylothorax can occur. Our review seeks to identify potential risk factors, modalities for early diagnosis, and novel interventions that may ameliorate the potential adverse effects of these surgical complications following esophagectomy. ispartof: Annals of the New York Academy of Sciences vol:1434 issue:1 pages:254-273 ispartof: location:United States status: Published online
Preoperative Considerations on the Thorax: Anatomy and Surgical Landmarks
2020
The thoracic wall is the higher part of the thorax consisting of a musculoskeletal structure including the mediastinum, the pleuropulmonary cavities, viscera, lymphatic, vascular, and nervous structures. Its dimensions are influenced by age, gender, and life style including physical training. It changes constantly in shape and size according to respiration: Generally, males show an abdominal pattern while females have usually a thoracic respiration pattern. The anatomy of the chest differs between men and women, with considerable variations among different ages and races. The skin is thicker in male than in female. In the male thorax, hair is frequently present and the mammary glands are un…
Three-dimensional geometric morphometrics of thorax-pelvis covariation and its potential for predicting the thorax morphology: A case study on Kebara…
2020
The skeletal torso is a complex structure of outstanding importance in understanding human body shape evolution, but reconstruction usually entails an element of subjectivity as researchers apply their own anatomical expertise to the process. Among different fossil reconstruction methods, 3D geometric morphometric techniques have been increasingly used in the last decades. Two-block partial least squares analysis has shown great potential for predicting missing elements by exploiting the covariation between two structures (blocks) in a reference sample: one block can be predicted from the other one based on the strength of covariation between blocks. The first aim of this study is to test w…
Independent right lung high frequency and left lung conventional ventilation in the management of severe air leak during ARDS
1995
Summary Pulmonary air leaks are one of the most common problems in patients with the adult respiratory distress syndrome, ARDS. We report what we believe to be the first case in which unilateral high-frequency ventilation combined with contralateral conventional positive pressure ventilation has been used successfully to manage severe air leak in an infant with ARDS.
Raiders from the sky: slavemaker founding queens select for aggressive host colonies.
2012
Reciprocal selection pressures in host–parasite systems drive coevolutionary arms races that lead to advanced adaptations in both opponents. In the interactions between social parasites and their hosts, aggression is one of the major behavioural traits under selection. In a field manipulation, we aimed to disentangle the impact of slavemaking ants and nest density on aggression of Temnothorax longispinosus ants. An early slavemaker mating flight provided us with the unique opportunity to study the influence of host aggression and demography on founding decisions and success. We discovered that parasite queens avoided colony foundation in parasitized areas and were able to capture more broo…
Do we really need new medical information about the Turin Shroud?
2014
Abstract Image processing of the Turin Shroud (TS) shows that the Man represented in it has undergone an under glenoidal dislocation of the humerus on the right side and lowering of the shoulder, and has a flattened hand and enophthalmos; conditions that have not been described before, despite several studies on the subject. These injuries indicate that the Man suffered a violent blunt trauma to the neck, chest and shoulder from behind, causing neuromuscular damage and lesions of the entire brachial plexus. The posture of the left claw-hand is indicative of an injury of the lower brachial plexus, as is the crossing of the hands on the pubis, not above the pubis as it would normally be, and …
