ATLS: Catheter and tube placement
The specific objectives of this experiment are: to evaluate the rack mounted equipment and medical supplies necessary for medical procedures; to evaluate the attachments, mounting points, and inner drawer assemblies for the medical supplies; and to evaluate the procedures for performing medical scenarios. The resources available in the HMF miniracks to accomplish medical scenarios and/or procedures include: medical equipment mounted in the racks; a patch panel with places to attach tubing and catheters; self contained drawers full of critical care medical supplies; and an ALS 'backpack' for deploying supplies. The attachment lines, tubing and associated medical supplies will be deployed and used with the equipment and a patient mannequin. Data collection is provided by direct observations by the inflight experimenters, and analysis of still and video photography
SOCIAL ATTENTION AND MEMORY IN YOUTH WITH ASD, ADNP SYNDROME, AND FOXP1 SYNDROME
The current study used eye tracking and behavioral measures to examine social attention and recognition memory in two rare genetic disorders commonly associated with autism spectrum disorder (ASD): ADNP syndrome and FOXP1 syndrome. Impairment in social functioning is considered a core deficit in ASD. Although individuals with ADNP syndrome and FOXP1 syndrome typically present with symptoms of ASD, research suggests several dissimilarities in symptom presence and severity between the groups. Thus, there is a need to clarify disorder-specific patterns of social attention and their relationships to observed social skills. A visual paired comparison eye tracking task was used to assess social attention and memory in youth with ADNP syndrome (n = 18) and FOXP1 syndrome (n = 9) compared to youth with idiopathic ASD (n = 90) and typically developing controls (n = 43). Diagnostic groups demonstrated similar within-group attention to social and non-social stimuli but differences in engagement with the presented stimuli depending on stimulus type and image location. Rare genetic disorder groups also demonstrated differences in preferential looking patterns for novel versus familiar stimuli. Correlations with behavioral measures were examined for each group, with the social problems domain of the CBCL demonstrating the highest correlations with the ADNP group and the socialization domains of caregiver-report interviews (i.e., Vineland-3, ADI-R) demonstrating the highest correlations with the FOXP1 group. These findings offer a characterization of social attention and memory patterns in youth with these rare conditions that yields insight into subtle differences in information processing across disorders
Permeability of the small intestinal mucus for physiologically relevant studies: Impact of mucus location and ex vivo treatment
The small intestinal mucus is a complex colloidal system that coats the intestinal mucosa. It allows passage on nutrients/pharmaceuticals from the gut lumen towards the epithelium, whilst preventing it from direct contact with luminal microorganisms. Mucus collected from intestinal tissue is often used in studies looking at inter-mucosal transport of food particulates, drug carriers, etc. However, detaching the highly hydrated native mucus from the tissue and storing it frozen prior to use may disrupt its physiological microstructure, and thus selective barrier properties. Multiple-particle tracking experiments showed that microstructural organisation of native, jejunal mucus depends on its spatial location in the intestinal mucosa. The inter-villus mucus was less heterogeneous than the mucus covering villi tips in the pig model used. Collecting mucus from tissue and subjecting it to freezing and thawing did not significantly affect (P > 0.05) its permeability to model, sub-micron sized particles, and the microviscosity profile of the mucus reflected the overall profiles recorded for the native mucus in the tissue. This implies the method of collecting and storing mucus is a reliable ex vivo treatment for the convenient planning and performing of mucus-permeability studies that aim to mimic physiological conditions of the transport of molecules/particles in native mucus
Range Expansion of \u3cem\u3eSigmodon hispidus\u3c/em\u3e (Hispid Cotton Rat) Into Reclaimed Coal Surface-Mines in Southeastern Kentucky
Sigmodon hispidus (Hispid Cotton Rat) is the most wide-spread species of Sigmodon in North America. In recent years, this species has expanded northward and westward in the western part of its range due to changes in habitat and climate. Evidence suggests northward expansion is also occurring in Kentucky. Since the 1980s, extensive coal mining via surface mining and mountain-top removal has transformed more than 2300 km2 of hardwood forests on the Cumberland Plateau of eastern Kentucky. Mining has transformed the landscape, once characterized by forests with deep valleys, steep slopes, and narrow, winding ridgetops into reclaimed sites with a relatively flat landscape dominated by grasses and forbs suitable for run-making rodents. Hispid Cotton Rat is thus poised to expand into the reclaimed mines of eastern Kentucky. We report the first record of Hispid Cotton Rat from a reclaimed-mine site and predict this species will expand its range north and east through this new habitat
Racemose neurocysticercosis.
BACKGROUND: Neurocysticercosis (NCC) is an invasive parasitic infection of the central nervous system caused by the larval stage of the tapeworm Taenia solium. The clinical manifestations of NCC depend on the parasitic load and location of infection, as well as the developmental stage of the cysticerci and host immune response, with symptoms ranging from subclinical headaches to seizures, cerebrovascular events, and life-threatening hydrocephalus. Racemose NCC represents a particularly severe variant of extraparenchymal NCC characterized by the presence of multiple confluent cysts within the subarachnoid space and is associated with increased morbidity and mortality, as well as a decreased response to treatment. Albendazole is the preferred drug for the treatment of racemose NCC due to its superior cerebrospinal fluid penetration compared to praziquantel and the ability to be used concomitantly with steroids.
CASE DESCRIPTION: In this report, we describe a 39-year-old man recently emigrated from Mexico with racemose NCC and hydrocephalus successfully treated with prolonged albendazole treatment, high-dose dexamethasone, and ventriculoperitoneal shunt placement for the relief of obstructive hydrocephalus.
CONCLUSIONS: Treatment of racemose NCC represents a significant clinical challenge requiring multimodal intervention to minimize infectious- and treatment-related morbidity. We review the clinical, diagnostic, and therapeutic features relevant to the management of this aggressive form of NCC

Anatomical variation in the formation and course of median nerve: a cadaveric study
Background: Median nerve is one of the terminal branches of brachial plexus. Its formed by the union of medial root and lateral root coming respectively from medial and lateral cords of brachial plexus. Knowledge of anatomical variations of median nerve at origin and course is important in repair of traumatic injuries and surgical correction of brachial plexus injuries. These conditions need dissection of median nerve and knowledge of its variations.Methods: Present study included 53 cadavers and 106 upper limbs from our department of Anatomy. In this study, anatomically embalmed cadavers which were kept for routine dissection for under graduates were included. The present study we studied the anatomical variations in origin and course of median nerve in arm. We also studied the relation of median nerve with axillary and brachial arteries.Results: In this study we found origin of median nerve from 3 roots in 26.41%, 4 roots from 1.88%. Regarding the relation of median nerve with axillary artery we observed in 8.49% cadavers median nerve lies medial to axillary artery and in 0.94% Median nerve is passing along the lateral side of brachial artery without crossing the artery.Conclusions: This study shows high percentage of deviations from normal anatomy in origin of median nerve. Anatomical variation in brachial plexus and adjacent arteries knowledge is important for anatomist, plastic surgeon and vascular surgeons.
