Objective: A matched, case?control study was conducted to examine the association between development of low birth weight (LBW) and maternal factors, including dietary intake, comorbidities, and socioeconomic factors, among women in Cap Haitien, Haiti. Design: Mothers who delivered LBW babies; defined as ?2.5?kg, were identified by review of the medical record and matched to mothers of similar age, parity, with normal birth weight (NBW) babies. A survey was administered consisting of Women's Dietary Diversity Score (WDDS), maternal reporting of comorbidities, income, and educational level. Subjects: Women were eligible if they delivered and had newborns weighed within the last 2 years. Total study participants consisted of 32 cases and 34 controls matched for age, parity, and month of delivery. Results: Mothers who consume eggs were 78% less likely to have given birth to a LBW infant (OR 0.22 (95% CI: 0.05?0.87). Mothers with NBW babies had a nonsignificant trend towards higher WDDS. The prevalence of hypertension in mothers who were seen in the clinic at least once over the past 2 years was found to be 27%, and 78% of mothers were not aware of their diagnosis. Conclusion: Enhancing maternal nutrition during pregnancy has broad implications for reducing LBW, improving fetal health and reducing fetal predilection for chronic diseases in adulthood. Longitudinal prospective studies are needed to evaluate the selective benefit of eggs and other high-quality foods in protecting fetal growth. Efforts to improve knowledge and awareness of hypertension in Haiti should be undertaken.

Computer Programming and Software - Abstract
… or, “It’s in the details, how to make complicated software perform like complicated hardware.” In attempts to minimize development time and quickly build an operational vehicle, NASA’s Space Launch System (SLS) has had to be intentional about integrated testing. Constraints on budget and schedule have required balance between testing needs and the desire for an integrated flight vehicle as soon as possible. To provide key insights early in design and analysis cycles, a large amount of effort has shifted into maturing and validating models at the component level with integrated testing as a means to validate their integration. In terms of SLS Navigation, this, and the model-based design approach have pushed explicit requirements for sensor models to be validated against flight hardware to high precision. This paper covers the approach taken to verify and validate the models for the two key navigation sensors on the SLS vehicle, the Redundant Inertial Navigation Sensor and the Rate Gyro Assembly. These models are used in performance evaluation, fault detection, and operations development extensively. Using a mix of data from hardware vendor documentation and testing reports, limited in-house testing, and integration activities, these models were able to be validated against flight hardware at multiple levels, from the internal software design to statistical behavior at the raw sensor and integrated box levels. The high level of insight into the hardware elements is instrumental to support flight certification activities and building confidence in SLS Navigation capability. Focused testing enabled additional insight and validation that proved invaluable and the resulting insights were used to focus and mature models. Additionally, of having validated performance-based hardware models enables a wide breadth of activities including detailed fault detection studies and integration into future vehicle frameworks, such as an upper stage and provide a valuable asset to continued SLS analysis and design.

In 1919 the Paris Peace Conference met to remake the world following the First World War. Among the most serious problems faced was the collapse of the multinational empires which once dominated central and eastern Europe, and the emergence of new successor states with unrecognised and overlapping borders. This fragmentation produced chaotic economic conditions as borders were frequently closed without warning, and the passage of goods and people consequently halted, delayed, or diverted. The peacemakers in Paris dispatched allied commissions in an attempt to resolve these problems. Using the files of several bodies sent to former Habsburg Silesia, this article elaborates on what this disintegrative moment meant for the region and its people. The turbulent events were not easily forgotten, and fostered visions of revenge, as well as European unity. One hundred years on and they still remain as an important historical reference point.

Objective The primary objective of this study was to compare one-year mortality in patients undergoing cardiac surgery with volatile anesthesia or total intravenous anesthesia (TIVA). Secondary objectives were to compare in-hospital and 30-day mortality, postoperative levels of creatine kinase (CK-MB) and cardiac troponin, and durations of tracheal intubation, intensive care unit (ICU) and hospital stays. Design Systematic review and meta-analysis of randomized controlled trials (RCTs). Setting International, multi-institution centers. Participants Adults patients undergoing heart surgery. Interventions Volatile anesthesia and TIVA. Measurements and Main Results Meta-analysis found no statistically significant difference between patients receiving TIVA and volatile anesthesia in one-year mortality (n = 6440, OR = 1.22, 95% CI 0.97 to 1.54, p = 0.09, Z = 1.67, I2 = 0%), troponin (n = 3127, SMD = 0.26, 95% CI -0.01 to 0.52, p = 0.05, Z = 1.92, I2 = 90%) and CK-MB concentration 24h postoperatively (n = 1214, SMD = 0.10, 95% CI -0.17 to 0.36, unadjusted p = 0.48, Z = 0.71, I2 = 79%), or time to tracheal extubation (n = 1059, SMD = 0.10, 95% CI -0.28 to 0.49, p = 0.60, Z = 0.53, I2 = 88%). The durations of ICU stay (n = 2003, SMD = 0.29, 95% CI 0.01 to 0.57, p = 0.04, Z = 2.05, I2 = 88%) and hospital stay (n = 1214, SMD = 0.42, 95% CI 0.10 to 0.75, p = 0.01, Z = 2.53, I2 = 91%) were shorter in the volatile anesthetic compared to TIVA group. Conclusions No significant differences in mortality (in-hospital, 30-day, 1-year), troponin and CK-MB concentrations 24 h postoperatively, or time to tracheal extubation were found between patients who had volatile anesthesia or TIVA. Compared to TIVA, volatile anesthesia was associated with shorter durations of hospital and ICU stays.

Correlational analysis, such as linear regression, does not imply causation. This paper introduces and applies a causal inference framework and a specific method, regression discontinuity, to thermal comfort field studies. The method utilizes policy thresholds in China, where the winter district heating policy is based on cities' geographical locations relative to the Huai River. The approximate latitude of the Huai River can be considered as a natural, geographical threshold, where cities near the threshold are quite similar, except for the availability of district heating in cities north of the threshold, creating a situation similar to a randomized experiment. Using the regression discontinuity method, we quantify the causal effects of the experiment treatment (district heating) on the physical indoor environments and subjective responses of building occupants. We found that mean indoor operative temperatures were 4.3 °C higher, and mean thermal sensation votes were 0.6 warmer due to the district heating. In contrast, using conventional correlational analysis, we demonstrate that the correlation between indoor operative temperature and thermal sensation votes does not accurately reflect the causal relationship between the two. We also show that the indoor operative temperature could be either positively or negatively correlated with occupants’ thermal satisfaction. However, we cannot conclude that increasing the indoor operative temperature in these circumstances will necessarily lead to higher or lower thermal satisfaction. This highlights the importance of causal inference methods in thermal comfort field studies and other observational studies in building science, where the regression discontinuity method might apply.

Medicine ,Science - Abstract
Abstract International building certification systems, such as the WELL and Leadership in Energy and Environmental Design (LEED) standards, play a pivotal role in the design of healthy and sustainable buildings. While LEED adopts a holistic approach to designing healthy and sustainable buildings, the WELL standard has a strong emphasis on human health, comfort, and well-being. Although prior research has revealed inconsistent results for occupant satisfaction in office buildings with WELL certification compared to buildings without WELL certification, or are certified using another certification system (e.g., LEED), most of these comparisons tend to lack methodological rigor. This study used a statistical procedure to match and compare 1634 occupant surveys from LEED-certified buildings to 1634 surveys from WELL-certified buildings. Six important architectural and experiential parameters were matched, masking their influence on the outcome. Overall building and workspace satisfaction was high in both WELL-certified buildings (94% and 87%) and LEED-certified (73% and 71%). We found that there is a 39% higher probability of finding occupants who are more satisfied in WELL-certified buildings compared to LEED-certified buildings, indicating occupant satisfaction is higher in buildings with WELL certification. Although we were unable to pinpoint the reason for higher occupant satisfaction in WELL-certified buildings, the results consistently showed that perceived indoor environmental quality was enhanced across all parameters except for the amount of space.

Philosophy - Abstract
In Fear and Trembling Kierkegaard (alias Johannes de Silentio) writes that Abraham intended to sacrifice Isaac for God’s sake as well as for his own sake. Drawing mainly on The Sickness unto Death I will argue that Kierkegaard construes Abraham as becoming a true self, that is, as someone who becomes self-transparent before God. What this means and how our relationship with God is supposed to be involved in the process of becoming a self is the focus of my paper. While various articles have been written on that topic, my aim here is to give the most charitable interpretation of Kierkegaard’s theses and the theological concepts involved.

microRNAs are small noncoding RNAs that play important roles in cancer regulation. In this study, we investigated the expression, functional effects and mechanisms of action of microRNA-29a (miR-29a) in glioblastoma (GBM). miR-29a expression levels in GBM cells, stem cells (GSCs) and human tumors as well as normal astrocytes and normal brain were measured by quantitative PCR. miR-29a targets were uncovered by target prediction algorithms, and verified by immunoblotting and 3′ UTR reporter assays. The effects of miR-29a on cell proliferation, death, migration and invasion were assessed with cell counting, Annexin V-PE/7AAD flow cytometry, scratch assay and transwell assay, respectively. Orthotopic xenografts were used to determine the effects of miR-29a on tumor growth. Mir-29a was downregulated in human GBM specimens, GSCs and GBM cell lines. Exogenous expression of miR-29a inhibited GSC and GBM cell growth and induced apoptosis. miR-29a also inhibited GBM cell migration and invasion. PDGFC and PDGFA were uncovered and validated as direct targets of miR-29a in GBM. miR-29a downregulated PDGFC and PDGFA expressions at the transcriptional and translational levels. PDGFC and PDGFA expressions in GBM tumors, GSCs, and GBM established cell lines were higher than in normal brain and human astrocytes. Mir-29a expression inhibited orthotopic GBM xenograft growth. miR-29a is a tumor suppressor miRNA in GBM, where it inhibits cancer stem cells and tumor growth by regulating the PDGF pathway.

Long-term monitoring of the thermal environment in office buildings has become increasingly relevant with the rise of wireless sensor networks. However, there is a notable absence of explicit guidelines for implementing monitoring strategies in such contexts. This lack of direction can lead to inconsistent deployment of sensor networks, resulting in higher maintenance costs and inaccurate long-term assessments of thermal conditions. Based on data analyses of high-accuracy, high-frequency field measurements conducted over a year or longer across multiple offices in Sydney and Shanghai, this study proposes a strategy for long-term temperature monitoring. The strategy advises practitioners to prioritize considerations such as air-conditioning type, room size, and space function when selecting ''representative'' sensor locations. Typically, sampling every 30 min is deemed adequate for shared offices where an error margin of ±0.5°C is acceptable. For environments with stable indoor temperatures, less frequent sampling intervals suffice. A power regression model tailored for offices equipped with central AC and no operable windows was developed to predict the maximum allowable sampling interval based on several days of indoor temperature monitoring in winter. Regarding monitoring duration, the study advocates a preferred sampling period of one year to comprehensively capture seasonal variations. Alternatively, a minimum monitoring period of four to six months commencing in late spring or early summer is identified as potentially sufficient. These findings offer valuable insights for optimizing long-term thermal monitoring practices in offices and may contribute to expanding the scope of thermal comfort standards.

Medicine ,Science - Abstract
Abstract Sleep is a pillar of human health and wellbeing. In high- and middle-income countries, there is a great reliance on heating, ventilation, and air conditioning systems (HVAC) to control the interior thermal environment in the bedroom. However, these systems are expensive to buy, maintain, and operate while being energy and environmentally intensive—problems that may increase due to climate change. Easily-accessible passive and low-energy strategies, such as fans and electrical heated blankets, address these challenges but their comparative effectiveness for providing comfort in sleep environments has not been studied. We used a thermal manikin to experimentally show that many passive and low-energy strategies are highly effective in supplementing or replacing HVAC systems during sleep. Using passive strategies in combination with low-energy strategies that elevate air movement like ceiling or pedestal fans enhances the cooling effect by three times compared to using fans alone. We extrapolated our experimental findings to estimate heating and cooling effects in two historical case studies: the 2015 Pakistan heat wave and the 2021 Texas power crisis. Passive and low-energy strategies reduced sleep-time heat or cold exposure by 69–91%. The low-energy strategies we tested require one to two orders of magnitude less energy than HVAC systems, and the passive strategies require no energy input. These strategies can also help reduce peak load surges and total energy demand in extreme temperature events. This reduces the need for utility load shedding, which can put individuals at risk of hazardous heat or cold exposure. Our results may serve as a starting point for evidence-based public health guidelines on how individuals can sleep better during heat waves and cold snaps without relying on HVAC.

Identifying disease-specific imaging features of idiopathic Normal Pressure Hydrocephalus (iNPH) is crucial to develop accurate diagnoses, although the abnormal brain anatomy of patients with iNPH creates challenges in neuroimaging analysis. We quantified cortical thickness and volume using FreeSurfer 7.3.2 in 19 patients with iNPH, 28 patients with Alzheimer's disease (AD), and 30 healthy controls (HC). We noted the frequent need for manual correction of the automated segmentation in iNPH and examined the effect of correction on the results. We identified statistically significant higher proportion of volume changes associated with manual edits in individuals with iNPH compared to both HC and patients with AD. Changes in cortical thickness and volume related to manual correction were also partly correlated with the severity of radiological features of iNPH. We highlight the challenges posed by the abnormal anatomy in iNPH when conducting neuroimaging analysis and emphasise the importance of quality checking and correction in this clinical population.

Abstract Wearable inertial measurement units (IMUs) are being used to quantify gait characteristics that are associated with increased fall risk, but the current limitation is the lack of contextual information that would clarify IMU data. Use of wearable video-based cameras would provide a comprehensive understanding of an individual’s habitual fall risk, adding context to clarify abnormal IMU data. Generally, there is taboo when suggesting the use of wearable cameras to capture real-world video, clinical and patient apprehension due to ethical and privacy concerns. This perspective proposes that routine use of wearable cameras could be realized within digital medicine through AI-based computer vision models to obfuscate/blur/shade sensitive information while preserving helpful contextual information for a comprehensive patient assessment. Specifically, no person sees the raw video data to understand context, rather AI interprets the raw video data first to blur sensitive objects and uphold privacy. That may be more routinely achieved than one imagines as contemporary resources exist. Here, to showcase/display the potential an exemplar model is suggested via off-the-shelf methods to detect and blur sensitive objects (e.g., people) with an accuracy of 88%. Here, the benefit of the proposed approach includes a more comprehensive understanding of an individual’s free-living fall risk (from free-living IMU-based gait) without compromising privacy. More generally, the video and AI approach could be used beyond fall risk to better inform habitual experiences and challenges across a range of clinical cohorts. Medicine is becoming more receptive to wearables as a helpful toolbox, camera-based devices should be plausible instruments.

Thomas Park
- Abstract
Clements Hall has occupied a central place on Southern Methodist University’s campus, both physically and socially, since the campus’ inception in 1915. Initially a women’s dormitory, it was later used by men after the construction of the Virginia and Snider dormitories. It included a dining space, a kitchen, and apartments for President Hyer and his family. In its time as a residential building, it housed engineering students, the football team, and briefly members of the Navy V-12 program. After complaints in the late 1950s, plans were made to renovate the building for use as classrooms and administrative space, offering services ranging from academic counseling to a print shop. The building has been intertwined with may key moments in Southern Methodist University’s history, witnessing the end of strict limitations on the social lives of its members, early attempts at desegregation in Texas, and the infamous William P. Clements football scandal. Despite its historical significance, Clements Hall has faded from its role as a social center on campus. The data for this paper was gathered from the DeGolyer Library Archives, the primary depository for documents on the history of Southern Methodist University, comprising blueprints, personal accounts of students and professors living in Clements Hall, newspaper articles on the events in the building, and photographs of the hall. I will compile these sources into a holistic view of life in the building through its history. The focus of this project was to look at the evolution of life at SMU through the lens of the various uses of Clements Hall throughout its growth.

This paper investigates the pattern of change in occupants’ satisfaction with the Indoor Environmental Quality (IEQ) of their workspace over time. Analyses were performed on a cumulative (2012–2023) database of responses to a Post-Occupancy Evaluation survey in Australia. 20,400 questionnaire responses from 226 office buildings were classified into five groups based on the length of time respondents had occupied their workspace. Associations between workspace satisfaction and the length of time respondents had occupied their workspace were also analysed for different gender and age cohorts. Our results show that occupant satisfaction generally decreased with the length of time they had been allocated to their present workspaces (the ‘honeymoon-hangover’ effect). People who have occupied their workspace for more than 5 years expressed lower overall satisfaction with their workspace than those who have been there for less than 6 months. The same pattern was observed for occupants’ satisfaction with other IEQ dimensions including building image and maintenance, indoor air quality, spatial comfort, and thermal comfort. This ‘honeymoon-hangover’ effect was evident across genders and age groups. Furthermore, there was negligible difference between the two genders on the ‘honeymoon-hangover’ effect, although thermal comfort and indoor air quality were generally less satisfactory for women than men. Respondents aged 30 yrs or less showed a larger decline in satisfaction over time compared to those over 50-yrs old. Within the 30-year-or-under age group, occupants who had spent more than 5 years at their workspaces consistently registered the lowest satisfaction score across all IEQ dimensions. Implications and impacts: The findings in this study have significant implications for the design of Post-Occupancy Evaluation (POE) surveys and for facility managers aiming to enhance occupants' satisfaction with their workspace and workplace.

Background. Urban Health Project (UHP) is a mission and vision- driven sum- mer internship at the University of Cincinnati College of Medicine that places first- year medical students at local community agencies that work with underserved populations. At the completion of their internship, students write Final Intern Reflections (FIRs). Methods . Final Intern Reflections written from 1987 to 2012 were read and coded to both predeter - mined categories derived from the UHP mission and vision statements and new categories created from the data themselves. Results. Comments relating to UHP's mission and vision were found in 47% and 36% of FIRs, respectively. Positive experiences outweighed negative by a factor of eight. Interns reported the following benefits: educational (53%), valuable (25%), rewarding (25%), new (10%), unique (6%), and life- changing (5%). Conclusions. Urban Health Project is successful in providing medical students with enriching experi- ences with underserved populations that have the potential to change their understanding of vulnerable populations.

Purpose. Physical activity (PA) has well-established health benefits, but most Americans do not meet national guidelines. In southeastern Missouri, trails have been developed to increase rates of PA. Although this has had success, broad-scale interventions will be needed to improve rates further. In this study, we surveyed residents of southeastern Missouri to identify ways to improve rates of PA. Methods. We conducted a telephone survey in 2015 of adults (n=524) from eight rural Missouri towns that had walking trails, regarding their activities and interests. Findings. Forty percent of respondents reported both walking and meeting PA recommendations, 29% reported walking but not meeting PA recommendations, and the remainder did not walk or did not answer. Respondents who used the trails were significantly more likely to meet PA recommendations (odds ratio = 2.7; 95% confidence interval = 1.7, 4.5). Certain values and interests that may encourage PA or draw people to trails were common. Conclusions. The group that walked but did not meet PA recommendations would be the ideal group to target for intervention, which could focus on their reported values and interests (e.g., personal relationships, being outdoors). Use of walking trails was associated with meeting PA recommendations.

This article presents some results on the energy demand in conventional bread baking and in the processing of frozen part baked breads, resulting from the “EU-FRESHBAKE” European project (FP6). Bread baking is one of the most energy demanding processes (around 4 MJ/kg), compared with other thermal processes such as canning. However, there is a large variability of data in the literature. For partial baking, bread has to be baked twice. It may also be frozen after part baking, which will increase the total energy demand. Results obtained with equipment used by craft bakeries are presented. Conventional and frozen part baked processes are compared. The effect of occupation ratio on the overall energy demand is also assessed. It was observed that 15–20% of the total energy is used for heating up the dough and 10–20% for crust drying. Pre-heating of the oven represents another significant energy demand. The energy demand for freezing is comparable to that for baking. An Energy Efficiency Index is used to assess the ratio of energy effectively transferred to the dough during baking. Part baked frozen technology demands about 2.2 times as much energy as conventional bread making process.

Objective. The object of this study was to increase our understanding of the social, clinical, radiographic and psychological consequences of child abuse after the initial insult and to describe the role of neurosurgery and other specialties in this context. Methods. A review of the literature on child abuse (using scientific journals, textbooks, and internet reports) was conducted, with special attention given to child abuse in infants. The biomechanical patterns of injury, the long-term neurological, psychological, and social outcomes and methods of rehabilitation are reviewed. Conclusions. Head injury associated with physical abuse carries a significantly worse clinical outcome than accidental trauma. Late findings in CT scans and MRI show evidence of cerebral atrophy in 100% and cerebral ischemia in 50% of physical abuse cases. Abuse and neglect have a strong impact in developing children, producing emotional, cognitive, and social problems that may persist throughout the rest of their lives. Outcome cannot be improved without an integrated rehabilitation strategy encompassing early field management, hospital therapy, precise targeting of educational and cognitive needs, and finally return to the community. New ancillary tests have emerged that are aimed at improving rehabilitation and illuminating the long-term physiological and functional impact of abuse.

With the rapid development of computer equipment, approximation by analytical solutions has become popular in mathematical modeling. Finite element (FE) analysis uses numerical methods to solve problems with physical phenomena, and these can be applied to various geometrically complex materials, such as brain. The FE formulation can provide such diverse domains as heat conduction, torsion of elastic material, diffusion and fluid flow, and it can view different objects of study in the neurosurgical field. In this article, the various applications of FE methods are introduced to illustrate the usefulness of the technique and the link between the external biomechanical aspect and internal phenomena in brain research.

We have previously described a novel lipoprotein particle consisting of phospholipids, apolipoprotein A-I (apoAI), lipopolysaccharide binding protein (LBP) and Factor H-related proteins (FHRP), and we termed these particles FALP (FHRP-associated lipoprotein particles). Highly purified preparations of FALP contain variable amounts of an unidentified polypeptide triplet of Mr ∼85 000 (tp85). Here we report that tp85 represents fragment D of fibrinogen, as confirmed by N-terminal amino acid sequencing and Western blot analysis with an antifibrinogen antibody. The physical association of fibrinogen with other components of FALP in plasma was further confirmed by sandwich ELISA by using monoclonal antibodies against apoAI, FHRP or LBP to capture the particles and polyclonal antifibrinogen as the detecting antibody. Furthermore, affinity chromatography with anti-FHRP-1–specific IgG showed that fibrinogen is co-immunodepleted with FALP and approximately 17% of total plasma fibrinogen are bound to FALP. LBP is a lipid transfer protein that moves lipopolysaccharide (LPS) to a binding site on CD14 or high-density lipoprotein (HDL). To determine whether fibrinogen affects the lipid transfer activity of LBP on FALP, this activity was measured in FALP prepared with and without fibrinogen. Neither activity of LBP was affected by fibrinogen. The abundance of FALP suggests, instead, an effect of FALP on the function or clearance of fibrinogen or fragment D. (Blood. 2000;95:198-204)

For calibration of a large capacity gas flow meter, a sonic nozzle bank may be used as a reference system. International standards (ISO9300:1990) allow installation of a single nozzle in a meter tube as a flow transfer standard. For multiple nozzles in a single tube, the effect of interference between sonic nozzles and the chamber wall must be measured to predict the discharge coefficient of a nozzle array from those of single nozzles. The interference effect between neighboring nozzles can be additional error sources in mass flow measurement. Sonic nozzles with three different throat diameters ( d =4.3, 8.1, and 13.4 mm) were tested in a single meter tube in three geometrical arrangements. The mass flow rate was measured against a primary gas flow standard system. Three installation plates for sonic nozzles were made to vary the distance between nozzles and distance from the chamber wall. Discharge coefficients of the three individual nozzles were in agreement with the ISO recommended equation within ±0.2%. Discharge coefficients of the nozzle bank calculated from those of the individual sonic nozzle were the same as the direct measurements within ±0.098% at the 95% confidence level for all cases. For these experiments, the results were not influenced by the proximity of the tube wall or the interaction of the nozzles.

The Effect of Intravenous Ketamine on Dissociation, Locomotor Activity, Information Processing, and Antinociception in Rats KD Radford1, TY Park2, S Moran3, LA Osborne1, KH Choi1,2,4 1Daniel K. Inouye Graduate School of Nursing; 2Department of Psychiatry; 3Structural Biology/Proteomics Core, Biomedical Instrumentation Center 4 Center for the Study of Traumatic Stress, USUHS, Background Bethesda, MD 20814 •Ketamine is a short acting dissociative anesthetic that non-competitively blocks glutamate at the N-methyl-D-aspartate (NMDA) receptor. •In addition to anesthesia environments, ketamine is used as a potent battlefield analgesic and also to treat chronic pain, depression, and post-traumatic stress disorder (PTSD) that is resistant to traditional treatments. •Health care providers use intravenous (IV) infusions of ketamine whereas, pre-clinical researchers primarily administer ketamine in rodent models via intraperitoneal (IP) injections. •This can lead to difficulty in clinical translation as there are pharmacokinetic differences, increased stress to animals during injection, increased potential for failed injections that occur outside the IP space, and clinical practice mostly uses IV injections. •Little is known regarding sub-anesthetic IV dosing for rats. •Therefore, our primary aim was to compare the effects of two sub-anesthetic IV ketamine doses (2 & 5mg/kg) on dissociative behaviors, locomotor activity, acoustic startle reflex (ASR)/pre-pulse inhibition (PPI), and anti-nociception in rats. •A secondary aim was to examine blood levels of ketamine (KET) and nor-ketamine (NKET) at 1, 20, & 50 minutes post bolus infusion. Methods Intravenous KET administration: The right jugular veins of male Sprague-Dawley rats (300±25g) were cannulated and tunneled under the skin to a 22g dorsal access port between scapulae. Animals were tested after a 7-day recovery. Ketamine hydrochloride (100mg/mL) was diluted to 2mg/mL or 5mg/mL and dosed at 2 or 5mg/kg IV in a counter bala, Background: Military health care providers administer ketamine, a short-acting dissociative anesthetic and potent analgesic, to injured service members on aircraft carriers at sea to remote battlefields. Clinicians also give ketamine to treat chronic pain, depression, and post-traumatic stress disorder (PTSD) resistant to traditional medications. Ketamine is typically administered intravenously (IV) in deployed environments and stateside clinical practice. However, pre-clinical researchers primarily use intraperitoneal (IP) injections in rodent studies. Pharmacokinetic differences, increased stress to animals, and IP injection failure rates are several issues that lead to translational concerns for future human clinical trials and practical applications that use the IV route. Little is known regarding effective IV ketamine doses for rats. Therefore, our primary aim was to compare the effect of 2 and 5mg/kg sub-anesthetic IV ketamine doses on dissociative behaviors, locomotor activity, acoustic startle reflex (ASR)/pre-pulse inhibition (PPI), and antinociception in rats. Our secondary aim was to measure ketamine serum levels at peak, 20, and 50 minutes after injection. Method: Male Sprague-Dawley rats (30050g) with indwelling jugular vein cannulas were given IV ketamine doses (0, 2, & 5 mg/kg) in a counter-balanced design. Dissociative behaviors (over 5 min), locomotor activity (over 15 min), ASR/PPI (at 20 min), and hotplate latency (20 to 90 min) were measured. Serum ketamine and norketamine levels were measured using liquid chromatography/mass spectrometry in a separate group of animals at peak, 20, and 50 min post injection. Locomotor activity and hotplate latency were analyzed with repeated measures two-way ANOVA. ASR/PPI and ketamine/norketamine serum levels were analyzed with one-way ANOVA and Tukey’s post-hoc analysis. Dissociative behaviors were analyzed with Kruskal-Wallis and Dunn’s post-hoc multiple comparison. P values < 0.05 were considered significant.

Previously unpublished data from over 600 office buildings in the Center for the Built Environment (CBE) Occupant Survey database are used to perform a systematic analysis of dissatisfaction in contemporary workspaces. A total of 81% of respondents expressed dissatisfaction with at least one aspect of their workspace, and 67% with more than one. Acoustics were the most common source of dissatisfaction, particularly related to people talking, speech privacy, and phones. Other challenges included a perceived lack of control over the temperature and insufficient space, along with other associated problems of densely populated offices. The analysis shows that context matters when understanding occupant dissatisfaction. Occupants of open-plan offices with low or no partitions were almost twice as likely to complain about their workspace than someone in a private, enclosed office. Being near a window decreased the likelihood of dissatisfaction compared with those who were not near a window. There was a clear relationship between self-perceived performance and satisfaction with the indoor environment. Dissatisfaction profiles found that acoustics, space, and privacy-related items co-occur for many occupants dissatisfied with more than one workspace aspect. 'Practical relevance' Post-occupancy surveys are a useful tool for evaluating whether an office environment supports occupants while conducting their work. While highlighting the successes is important, complaints from dissatisfied occupants can identify issues and pinpoint reasons why spaces do not meet expectations. The reported challenges generally relate to the simultaneous reduction in control and personalization with increasingly open and densely populated layouts. Occupant dissatisfaction may impact performance given the reported relationship between satisfaction with the environment and feeling supported by the workspace to complete work tasks. The themes emerging from this analysis identify common dissatisfaction sources that can serve as an empirical basis to identify common problems in contemporary workspace designs.

Tissue factor pathway inhibitor (TFPI) is a Kunitz-type plasma protease inhibitor that inhibits factor Xa and the factor VIIa/tissue factor catalytic complex. It plays an important role in feedback inhibition of the coagulation cascade (Broze, Annu Rev Med 46:103, 1995). TFPI has also been used successfully to prevent lethality and attenuate coagulopathic responses in a baboon model of septic shock (Creasey et al, J Clin Invest 91:2850, 1993; and Carr et al, Circ Shock 44:126, 1995). However, the mechanism of reduced mortality in these animals could not be explained merely by the anticoagulant effect of TFPI, because TFPI-treated animals also had a significantly depressed interleukin-6 response. Moreover, inhibition of coagulopathic responses by other anticoagulants has failed to block the organ damage or lethal effect of endotoxic shock (Coalson et al, Circ Shock 5:423, 1978; Warr et al, Blood 75:1481, 1990; and Taylor et al, Blood 78:364, 1991). We show here that recombinant TFPI can bind to endotoxin in vitro. This binding prevents interaction of endotoxin with both lipopolysaccharide binding protein and CD14, thereby blocking cellular responses.

Medicine ,Science - Abstract
Abstract Growth in energy use for indoor cooling tripled between 1990 and 2016 to outpace any other end use in buildings. Part of this energy demand is wasted on excessive cooling of offices, a practice known as overcooling. Overcooling has been attributed to poorly designed or managed air-conditioning systems with thermostats that are often set below recommended comfort temperatures. Prior research has reported lower thermal comfort for women in office buildings, but there is insufficient evidence to explain the reasons for this disparity. We use two large and independent datasets from US buildings to show that office temperatures are less comfortable for women largely due to overcooling. Survey responses show that uncomfortable temperatures are more likely to be cold than hot regardless of season. Crowdsourced data suggests that overcooling is a common problem in warm weather in offices across the US. The associated impacts of this pervasive overcooling on well-being and performance are borne predominantly by women. The problem is likely to increase in the future due to growing demand for cooling in increasingly extreme climates. There is a need to rethink the approach to air-conditioning office buildings in light of this gender inequity caused by overcooling.

The avidity of leukocyte integrin CR3 (Mac-1, CD11b/CD18, α m β 2 ) on neutrophils (PMN) may be rapidly modulated by several agonists. We describe a method for determining the avidity of these receptors by measuring the adhesion of PMN to fibrinogen-coated surfaces. Cells are loaded with a succinimidyl ester of carboxyfluorescein diacetate, which is deacetylated by intracellular esterases yielding a highly fluorescent carboxyfluorescein that remains trapped within the PMN. The number of cells adhering to fibrinogen-coated wells of Terasaki microplates is quantitated with a fluorescence plate reader. Stimulation of PMN with a number of agonists, including PMA, fNLLP, Ca-ionophore A23187, interleukin-8, tumor necrosis factor and lipopolysaccharide strongly increased adhesion to fibrinogen, which was CD11b/CD18 dependent. The extent of cell adhesion depended on stimulus concentration and incubation time. This assay requires little time, utilizes small numbers of cells and does not require hazardous reagents.
