Glycocalyx Degradation Is Independent of Vascular Barrier Permeability Increase in Nontraumatic Hemorrhagic Shock in Rats.

BACKGROUND Glycocalyx shedding after traumatic hemorrhagic or septic shock, as well as different resuscitation fluids, has been causally linked to increased vascular barrier permeability (VBP) resulting in tissue edema. In nontraumatic hemorrhagic shock (NTHS), it remains questionable whether glycocalyx degradation in itself results in an alteration of VBP. The composition of fluids can also have a modulatory effect on glycocalyx shedding and VBP. We hypothesized that the shedding of the glycocalyx during NTHS has little effect on VBP and that the composition of fluids can modulate these effects. METHODS Fully instrumented Wistar-albino rats were subjected to a pressure-controlled NTHS (mean arterial pressure of 30 mm Hg) for 60 minutes. Animals were fluid resuscitated with Ringer's acetate, balanced hydroxyethyl starch (HES) solution, or 0.9% normal saline to a mean arterial pressure of 80 mm Hg and compared with shams or nonresuscitated NTHS. Glycocalyx shed products were determined at baseline and 60 minutes after fluid resuscitation. Skeletal muscle microcirculation was visualized using handheld vital microscopy. VBP changes were assessed using plasma decay of 3 fluorescent dyes (40- and 500-kDa dextran and 70-kDa albumin), Evans blue dye exclusion, intravital fluorescence microscopy, and determination of tissue edema (wet/dry weight ratio). RESULTS All glycocalyx shedding products were upgraded as a result of NTHS. Syndecan-1 significantly increased in NTHS (mean difference, -1668; 95% confidence interval [CI], -2336 to -1001; P < .0001), balanced crystalloid (mean difference, -964.2; 95% CI, -1492 to -436.4; P = .0001), and HES (mean difference, -1030; 95% CI, -1594 to -465.8; P = .0001) groups at the end of the experiment compared to baseline. Hyaluronan levels were higher at the end of the experiment in nonresuscitated NTHS (-923.1; 95% CI, -1216 to -630; P = .0001) and balanced crystalloid (-1039; 95% CI, -1332 to -745.5; P = .0001) or HES (-394.2; 95% CI, -670.1 to -118.3; P = .0027) groups compared to controls. Glycocalyx shedding resulted in microcirculation alterations as observed by handheld video microscopy. Total vessel density was altered in the normal saline (mean difference, 4.092; 95% CI, 0.6195-7.564; P = .016) and hemorrhagic shock (mean difference, 5.022; 95% CI, 1.55-8.495; P = .0024) groups compared to the control group, as well as the perfused vessel density and mean flow index. Despite degradation of endothelial glycocalyx, VBP as determined by 4 independent assays remained intact and continued to be so following fluid resuscitation. CONCLUSIONS NTHS induced glycocalyx shedding and microcirculation alterations, without altering VBP. Fluid resuscitation partially restored the microcirculation without altering VBP. These results challenge the concept that the glycocalyx barrier is a significant contributor to VBP.

Epidemiology of tick‐borne pathogens in the semi‐arid and the arid agro‐ecological zones of Punjab province, Pakistan

Tick-borne diseases (TBDs) have a large impact on animal health and the livelihood of livestock owners, particularly in developing countries. Although climatic and ecological conditions in Pakistan may favour the transmission of tick-borne pathogens (TBPs), only a few systematic studies have been carried out on TBPs and the diseases that they cause in this country. To improve our understanding of the distribution of TBPs, 3,807 ticks were collected from ruminants (n = 369) on 108 livestock farms (semi-arid zone = 36, arid zone = 72) in Punjab Province. After morphological identification ticks were pooled into 405 pools (Hyalomma anatolicum = 300, Rhipicephalus microplus = 89, Hyalomma dromedarii = 9, Rhipicephalus turanicus = 7) based on their species, locality of collection, and the host. DNA from each pool was screened by a Reverse Line Blot (RLB) hybridization assay for the presence of Anaplasma, Ehrlichia, Rickettsia, Babesia, and Theileria species. DNA from at least one TBP was found in 142 (35.1%) pools. Among the positive pools, 91 (64.1%) had a mixed infection with two or more TBPs, whereas 51 (35.9%) pools were infected with a single TBP. The detected pathogens not only included species that were known to be endemic in Pakistan, such as Theileria annulata (6.7%), Theileria orientalis (3.5%), Anaplasma marginale (5.7%), Anaplasma centrale (2.7%), Anaplasma ovis (1.5%), Babesia bigemina (0.7%), and Babesia bovis (0.2%), but also several TBPs that had not been reported to occur in Pakistan before. This included Ehrlichia minasensis (3.2%), an Anaplasma platys-like organism (1.2%), Babesia occultans (0.2%), and Rickettsia massiliae (0.2%), as well as two previously uncharacterized species: Ehrlichia sp. Multan (18.0%) and Anaplasma sp. (BL099-6) (2.22%). The pathogenicity of these novel species remains to be examined. This study shows that a much broader spectrum of TBPs is present in Pakistan than previously thought, including several zoonotic pathogens.
Hypertension and childhood migration: a nationwide study of 2.7 million adolescents.

OBJECTIVES Immigration studies can shed light on hypertension development and reveal high-risk populations. To this end, we investigated the association between age at immigration and hypertension occurrence at adolescence among immigrants to Israel. METHODS We analyzed cross-sectional data on 2 681 294 adolescents assessed for mandatory military service at approximately 17 years of age between 1967 and 2016. The study population constituted of 410 488 immigrants with origins in Ethiopia, Middle East and North Africa, Former USSR and Western Countries. Age at immigration was categorized into 0-5, 6-11 and 12-19 years. Odds ratios (ORs) for hypertension were calculated according to age at immigration with Israel-born participants as controls. Models were made to account for possible confounders. Additionally, the study population was stratified by country of origin and each immigrant group referenced to Israel-born participants of the same origin. RESULTS In the fully-adjusted model, immigrants arriving until age 11 years had comparable ORs for hypertension to the Israeli-born reference group, whereas recent immigrants, arriving at age 12-19 years had a marked lower OR of 0.30 (95% CI 0.27-0.33; P < 0.001). The lower hypertension odds among recent immigrants persisted in all models and when the study sample was stratified by sex and origin, with all but those of Western origin showing a graded decrease with increasing age at migration categories. CONCLUSION Immigrants arriving earlier in childhood lose their protection against hypertension at adolescence relative to the Israeli-born, likely because of lifestyle acculturation. Prevention programs are needed, beginning upon arrival and placing emphasis on nutritional and physical activity habits.
Moderate heritability and low evolvability of sperm morphology in a species with high risk of sperm competition, the collared flycatcher Ficedula albicollis

Spermatozoa represent the morphologically most diverse type of animal cells and show remarkable variation in size across and also within species. To understand the evolution of this diversity, it is important to reveal to what degree this variation is genetic or environmental in origin and whether this depends on species’ life histories. Here we applied quantitative genetic methods to a pedigreed multigenerational data set of the collared flycatcher Ficedula albicollis, a passerine bird with high levels of extra‐pair paternity, to partition genetic and environmental sources of phenotypic variation in sperm dimensions for the first time in a natural population. Narrow‐sense heritability (h2) of total sperm length amounted to 0.44 ± 0.14 SE, whereas the corresponding figure for evolvability (estimated as coefficient of additive genetic variation, CVa) was 0.02 ± 0.003 SE. We also found an increase in total sperm length within individual males between the arrival and nestling period. This seasonal variation may reflect constraints in the production of fully elongated spermatozoa shortly after arrival at the breeding grounds. There was no evidence of an effect of male age on sperm dimensions. In many previous studies on laboratory populations of several insect, mammal and avian species, heritabilities of sperm morphology were higher, whereas evolvabilities were similar. Explanations for the differences in heritability may include variation in the environment (laboratory vs. wild), intensity of sexual selection via sperm competition (high vs. low) and genetic architecture that involves unusual linkage disequilibrium coupled with overdominance in one of the studied species.
Trends in Small-Cell Lung Cancer Survival in 1993–2006 Based on Population-Based Cancer Registry Data in Japan

Background Lung cancers are classified into small-cell lung cancer (SCLC) and non-small-cell lung cancer due to their different treatment and prognosis. Although many studies have reported the specific survival of SCLC patients treated at cancer hospitals, survival from population-based data has rarely been reported. Methods We analyzed survival of SCLC cases diagnosed from 1993 through 2006 from a population-based cancer registry of six prefectures. To assess trends in SCLC survival, we defined three periods that mirrored developments in SCLC treatment: period 1, 1993–1998; period 2, 1999–2001; and period 3, 2002–2006. Assessments were based on relative survival (RS), excess hazard, and conditional survival. Results A total of 10,911 SCLC patients were analyzed. Five-year RS among limited disease SCLC (LD-SCLC) in periods 1 to 3 was 16.8%, 21.1%, and 21.4%, respectively. Five-year RS among extensive disease SCLC (ED-SCLC) in periods 1 to 3 was 2.3%, 2.8%, and 2.7%, respectively. Improvement in 5-year RS in periods 2 and 3 compared with period 1 was significant among both LD- and ED-SCLC patients (all P < 0.001). Conditional 5-year RS of LD-SCLC increased from 21% at year 0 to 73% at year 5, while that of ED-SCLC was 3% at year 0 and 53% at year 5. Conclusions The prognosis of SCLC patients improved from 1999–2001 but plateaued in 2002–2006, after which no further significant improvement was seen. Continuous survey based on population-based data is helpful in monitoring the impact of developments in treatment.
Epidemiological trend in inflammatory bowel disease in Taiwan from 2001 to 2015: a nationwide populationbased study

Background/Aims Incidences of inflammatory bowel disease (IBD), ulcerative colitis (UC), and Crohn’s disease (CD), have been increasing in Asia. In this study, we report the relevant clinical characteristics and determined the epidemiological trend of IBD in Taiwan from 2001 to 2015. Methods A retrospective study was conducted to analyze data recorded from January 2001 through December 2015 in the registered database compiled by the National Health Insurance and provided by the Ministry of Health and Welfare, Taiwan. Results A total of 3,806 patients with catastrophic IBD illness were registered from 2001 to 2015 in Taiwan (CD, 919; UC, 2,887). The crude incidence of CD increased from 0.17/100,000 in 2001 to 0.47/100,000 in 2015, whereas that of UC increased from 0.54/100,000 in 2001 to 0.95/100,000 in 2015. The prevalence of CD increased from 0.6/100,000 in 2001 to 3.9/100,000 in 2015, whereas that of UC increased from 2.1/100,000 in 2001 to 12.8/100,000 in 2015. The male-to-female ratio in the study sample was 2.19 for CD and 1.62 for UC. The median age of those registered with CD was lower than that of those registered for UC: 38.86 and 44.86 years, respectively. A significantly greater increase in CD incidence rate was identified among 20 to 39-year-old compared with other age groups. Conclusions Using Taiwan’s nationwide insurance database, we determined that the number of patients with CD increased more rapidly during the study period than the number of patients with UC, especially among age 20 to 39-year-old, resulting in a decreased UC-to-CD ratio.
The Spatial Order of Physeal Maturation in the Normal Human Knee Using Magnetic Resonance Imaging

Background: The spatial order of physeal maturation around the distal tibia has been shown to place adolescent patients at risk for certain transitional injuries, such as Tillaux or triplane fractures. Less is known about physeal maturation around the knee. The purpose of this study was to establish the spatial order of physeal maturation in the normal human knee using magnetic resonance imaging (MRI). Methods: We retrospectively collected all knee MRI scans from patients presenting to our institution from January 2004 to January 2014. Patients who were suspected on the basis of clinical or radiographic findings of having abnormal knee physeal development or injury were excluded. We then applied a previously described MRI staging system of knee physeal maturation to the MRI scans of the remaining patients at 8 defined knee locations. Associations between the stage of maturation and mean chronological age were then evaluated across the 8 knee locations. Interrater and intrarater reliabilities were assessed. Results: A total of 165 knee MRI scans (from 98 boys, 67 girls) met the inclusion criteria. Significant differences were found between each stage of physeal maturation and the mean chronological ages at all 8 knee locations for both boys and girls (each, P<0.001). Interestingly, within each stage of physeal maturation, no significant difference was found in the mean chronological ages at any of the 8 knee locations, suggesting that physeal development occurs uniformly in the normal human knee for both boys and girls. Interrater and intrarater reliability were nearly perfect at all locations. Conclusions: The spatial order of physeal maturation in the normal human knee was uniform across 8 knee locations for both boys and girls. This uniformity may help to explain why transitional injuries do not follow a recognizable pattern in the knee. Furthermore, the uniformity aids with surgical decision making, because minimal growth modulation or disturbance is likely when early physeal closure is present in a portion of the physis. Level of Evidence: Level III.
Factor structure of the Behavioral Assessment Screening Tool (BAST) in traumatic brain injury

Abstract Objective: Establish the factor structure of the Behavioral Assessment Screening Tool (BAST), a self-reported emotional/behavioral symptom measure for adults with traumatic brain injury (TBI). Setting: Community. Participants: Community-dwelling adults with moderate–severe TBI (n = 162; n = 110). Design: Assessment development (cohort study). Main measures: Behavioral Assessment Screening Tool. Results: The original BAST included 61 items (55 primary, six secondary), an Environmental Context checklist including recent major life events, and three open-ended questions about other relevant factors. Two rounds of pilot testing and exploratory factor analysis of the BAST (n = 162; n = 110) reduced the total items to 37 primary items and six secondary coping items. The final BAST had a five-factor solution with communalities ranging from 0.323 to 0.771. Internal consistency reliabilities ranged from acceptable to excellent for all factors (Cronbach’s α = 0.76–0.90). The items related to coping, given only to those endorsing stress, had a two-factor solution with communalities ranging from 0.224 to 0.605, but demonstrated acceptable to poor internal consistency (Cronbach’s α = 0.46–0.68). Participants rated ease of use and overall satisfaction with completing the scale as high, with mean scores of 6.42 and 6.22 out of 7, respectively. Conclusions: The BAST, a measure of behavioral and emotional symptoms after TBI, has a multidimensional factor structure with evidence of good internal consistency reliability. Future work will evaluate the convergent, discriminant, and discriminative validity of the BAST and employ item response theory analyses to further develop a short version for mobile health assessment. Implications for Rehabilitation Long-term monitoring of behavioral and emotional symptoms after traumatic brain injury could improve clinical management and reduce negative participation and quality of life outcomes. The Behavioral Assessment Screening Tool demonstrates reliability for use among adults with chronic traumatic brain injury, through its factor structure and internal consistency reliabilities, to measure chronic behavioral and emotional symptoms. The Behavioral Assessment Screening Tool is a screening tool to identify potential behavioral and emotional problems that individuals with chronic traumatic brain injury may be experiencing; it could be implemented in a proactive, rather than reactive, system for long-term monitoring of these symptoms to improve early identification of clinical disorders.
In vivo evolution of viral virulence: switching of deformed wing virus between hosts results in virulence changes and sequence shifts

The health of the Western honey bee is threatened by a global epidemic of deformed wing virus (DWV) infections driven by the ectoparasitic mite Varroa destructor acting as mechanical and biological virus vector. Three different variants of DWV, DWV-A, -B and -C exist. Virulence differences between these variants and their relation to V. destructor are still controversially discussed. We performed laboratory experiments to analyze the virulence of DWV directly isolated from crippled bees (DWVP0 ) or after one additional passage in bee pupae (DWVP1 ). We demonstrated that DWVP0 was more virulent than DWVP1 for pupae, when pupal mortality was taken as virulence marker, and for adult bees, when neurotropism and cognitive impairment were taken as virulence markers. Phylogenetic analysis supported that DWV exists as quasispecies and showed that DWVP0 clustered with DWV-B and DWVP1 with DWV-A when the phylogeny was based on the master sequences of the RNA-dependent RNA polymerase but not so when it was based on the VP3 region master sequences. We propose that switching of DWV between the bee and the mite host is accompanied by changes in viral sequence, tissue tropism and virulence and that the RNA-dependent RNA polymerase is involved in determining host range and virulence.
Investigation on Simulation-Based Specific Absorption Rate in Ultra-Wideband Antenna for Breast Cancer Detection

The electrical properties of the cancer affected cell or malignant tumor cell are completely different from normal healthiest breast tissue. Specific absorption rate (SAR) is used as one of the best parameter to identify the malignant tissue in breast with the help of electrical properties of the human breast tissue, for example, permittivity and conductivity. The design of modified octagonal shaped ultra-wideband monopole microstrip antenna with size of $27\times 29\times 1.6$ mm3, fabricated with FR-4 material, is found suitable for ultra-wideband applications and used to detect the cancer. The antenna impedance bandwidth of simulated and measured results are good (S11 < −10 dB) and its operating frequency ranges from 3 to 15 GHz with voltage standing wave ratio ≤ 2. A 3-D breast model is designed with 60 mm radius, and simulated SAR values are tabulated for skin, fatty tissue, glandular tissue, and tumor. As glandular tissue is one of the softest tissues in human female breast, it has the possibility of developing tumor in lobules and ducts. The tumors of different size are incorporated in glandular tissue. It is found that the SAR value varies based on the tumor size in glandular tissue.
Production of Ethanol from Cereal Food Fines using Dilute-Acid Hydrolysis

Cereal food fines are a leftover by-product from breakfast cereal processing that is typically sold as animal feed or used as a pet food ingredient; however this product could be of greater value as a feedstock for the production of fuel ethanol via fermentation. In order for this material to be fermented it has to be broken down in to simple sugars using hydrolysis. One method of hydrolysis is called dilute-acid hydrolysis, whereby low concentrations of acid are added to the feedstock to facilitate the breaking of chemical bonds. This study investigates the effect of different concentrations of acid to determine optimal conditions for the production of ethanol. It was found that higher concentrations of acid yielded greater production of ethanol and, overall, this particular feedstock showed promise as a future source of fuel ethanol
The Effect of Soybean Extracts on Serum Lipid Profile and the Accumulationof Free Cholesterol and Cholesteryl Ester in the Aorta, Carotid Artery and IliacArtery-Experimental Study

Background: We evaluated the effect of soybean extracts on serum lipoprotein profile and cholesterol accumulation on the arterial walls. Objective and design: Sixty-four female Sprague-Dawley rats were randomly divided into eight groups. Soybean extracts were given to the rats via oral gavage every day for eight weeks, after which serum was collected. In the thoracic aorta, left carotid artery, and right iliac artery, we measured the lipoprotein fractions in the serum and the accumulation of free cholesterol and cholesteryl ester, which are predictors of subclinical atherosclerosis. Results: After eight weeks of a continuous soybean diet, only two groups showed a lipid-lowering effect (n-hexane extract for 200 mg/kg dose and ethyl acetate extract for 200 mg/kg dose). We found lower free cholesterol and cholesteryl ester accumulation in the aortas and iliac arterial walls only in these two groups. Conclusion: The results indicated that soybean extract intake leads to weight change and may influence lipid metabolism. The positive effects of the soybean diet involved not only serum lipids but also aortic wall cholesterol accumulation.
