Doppler ultrasonographic, oscillometric sphygmomanometric, and photoplethysmographic techniques for noninvasive blood pressure measurement in anesthetized cats.

Blood pressure (BP) measurements obtained using 3 indirect BP measuring instruments, a Doppler ultrasonic flowmeter, an oscillometric device, and a photoplethysmograph, were compared with direct arterial pressure measurements in 11 anesthetized cats. The standard deviation of the differences (SDD) between direct and indirect pressure measurements were not significantly different from each other (P < .01), and ranged from 10.82 to 24.32 mm Hg. The high SDD values indicate that indirect BP estimates obtained with all these devices must be interpreted cautiously in individual patients. The mean errors (calculated as the sum of the differences between direct and indirect pressure measurements divided by the number of observations) of the 3 indirect devices were significantly different for systolic (SAP), diastolic (DAP), and mean (MAP) arterial pressures (P < .05). The Doppler and photoplethysmographic devices had the highest overall accuracy, as indicated by mean error values of less than 10 mm Hg. Correlation coefficients varied from . 88 to . 96 for the Doppler flowmeter, and from . 85 to . 94 for the photoplethysmograph; for both devices, the regression line slopes were close to unity. The Doppler flowmeter detected a pulse under all experimental conditions. The photoplethysmograph was also efficient in obtaining BP measurements, obtaining over 90% of SAP, DAP, and MAP readings attempted. The oscillometric device was the least accurate, with mean error values varying from 10 to 22 mm Hg. Correlation coefficients were high (.90 to .94) for this device, but the slopes of the regression lines were 0.7 to 0.8, indicating a trend for increased error at higher BP. The oscillometric device tended to underestimate BP by increasing amounts as the BP increased. The oscillometric device was the least efficient device for obtaining BP measurements (P < .01).
Global burden of transmitted HIV drug resistance and HIV-exposure categories: a systematic review and meta-analysis

Objectives:Our aim was to review the global disparities of transmitted HIV drug resistance (TDR) in antiretroviral-naive MSM, people who inject drugs (PWID) and heterosexual populations in both high-income and low/middle-income countries. Design/methods:We undertook a systematic review of the peer-reviewed English literature on TDR (1999–2013). Random-effects meta-analyses were performed to pool TDR prevalence and compare the odds of TDR across at-risk groups. Results:A total of 212 studies were included in this review. Areas with greatest TDR prevalence were North America (MSM: 13.7%, PWID: 9.1%, heterosexuals: 10.5%); followed by western Europe (MSM: 11.0%, PWID: 5.7%, heterosexuals: 6.9%) and South America (MSM: 8.3%, PWID: 13.5%, heterosexuals: 7.5%). Our data indicated disproportionately high TDR burdens in MSM in Oceania (Australia 15.5%), eastern Europe/central Asia (10.2%) and east Asia (7.8%). TDR epidemics have stabilized in high-income countries, with a higher prevalence (range 10.9–12.6%) in MSM than in PWID (5.2–8.3%) and heterosexuals (6.4–9.0%) over 1999–2013. In low/middle-income countries, TDR prevalence in all at-risk groups in 2009–2013 almost doubled than that in 2004–2008 (MSM: 7.8 vs. 4.2%, P = 0.011; heterosexuals: 4.1 vs. 2.6%, P < 0.001; PWID: 4.8 vs. 2.4%, P = 0.265, respectively). The risk of TDR infection was significantly greater in MSM than that in heterosexuals and PWID. We observed increasing trends of resistance to non-nucleoside reverse transcriptase and protease inhibitors among MSM. Conclusion:TDR prevalence is stabilizing in high-income countries, but increasing in low/middle-income countries. This is likely due to the low, but increasing, coverage of antiretroviral therapy in these settings. Transmission of TDR is most prevalent among MSM worldwide.
Study on Application of Static Magnetic Field for Adjuvant Arthritis Rats

In order to examine the effectiveness of the application of static magnetic field (SMF) on pain relief, we performed a study on rats with adjuvant arthritis (AA). Sixty female Sprague–Dawley (SD) rats (age: 6 weeks, body weight: approximately 160 g) were divided into three groups [SMF-treated AA rats (Group I), non-SMF-treated AA rats (Group II) and control rats (Group III)]. The SD rats were injected in the left hind leg with 0.6 mg/0.05 ml Mycobacterium butyrium to induce AA. The rats were bred for 6 months as chronic pain model. Thereafter, the AA rats were or were not exposed to SMF for 12 weeks. We assessed the changes in the tail surface temperature, locomotor activity, serum inflammatory marker and bone mineral density (BMD) using thermography, a metabolism measuring system and the dual-energy X-ray absorptiometry (DEXA) method, respectively. The tail surface temperature, locomotor activity and femoral BMD of the SMF-exposed AA rats were significantly higher than those of the non-SMF-exposed AA rats, and the serum inflammatory marker was significantly lower. These findings suggest that the pain relief effects are primarily due to the increased blood circulation caused by the rise in the tail surface temperature. Moreover, the pain relief effects increased with activity and BMD of the AA rats.
COMPARISON OF DRUG EFFLUX TRANSPORT KINETICS IN VARIOUS BLOOD-BRAIN BARRIER MODELS

The present study quantitatively compared the drug efflux transport kinetics of 2′,7′-bis(2-carboxyethyl)-5(6)-carboxyfluorescein acetoxymethyl ester (BCECF-AM) and its fluorescent metabolite 2′,7′-bis(2-carboxyethyl)-5(6)-carboxyfluorescein (BCECF) in various blood-brain barrier (BBB) models. BCECF-AM was exposed to freshly isolated bovine brain microvessels (BBM), primary cultured bovine brain microvessel endothelial cells (BBMEC), and MDCK-MDR1 cells for 30 min in the presence or absence of the P-glycoprotein (P-gp) inhibitor N-(4-[2-(1,2,3,4-tetrahydro-6,7-dimethoxy-2-isoquinolinyl)ethyl]-phenyl)-9,10-dihydro-5-methoxy-9-oxo-4-acridine carboxamide (GF120918). P-gp transport kinetics were determined indirectly by calculating the difference in BCECF accumulation when P-gp was functional and completely inhibited by GF120918 (3.2 μM). Multidrug resistance-associated protein (MRP) transport kinetics were determined by measuring the amount of BCECF transported out of the cell over time. For P-gp-related transport, Km values for BCECF-AM were approximately the same in all three models (around 2 μM), whereas the Vmax was 4-fold greater in the BBM than in the BBMEC or MDCKII-MDR1 cells. For MRP-related transport, Km values for BCECF varied widely among the three BBB models with a rank order of MDCKII-MDR1 < BBMEC < BBM. Like P-gp, the Vmax of BCECF for MRP-related transport was overwhelmingly higher in the BBM compared with the cultured cells. Because differences in the expression of P-gp, MRP5, and MRP6 were observed in the various BBB models using reverse transcription-polymerase chain reaction techniques, the disparity in transport kinetics between the BBB models may be linked to variations in the amount or type of drug efflux transporters expressed in each model. The present study introduces a method of quantitatively evaluating drug efflux transport kinetics in the BBB.
Improvement in pulmonary function and elastic recoil after lung-reduction surgery for diffuse emphysema.

BACKGROUND Pulmonary function may improve after surgical resection of the most severely affected lung tissue (lung-reduction surgery) in patients with diffuse emphysema. The basic mechanisms responsible for the improvement, however, are not known. METHODS We studied 20 patients with diffuse emphysema before and at least three months after either a unilateral or a bilateral lung-reduction procedure. Clinical benefit was assessed by measurement of the six-minute walking distance and the transitional-dyspnea index, which is a subjective rating of the change from base line in functional impairment and the threshold for effort- and task- dependent dyspnea. Pressure-volume relations in the lungs were measured with static expiratory esophageal-balloon techniques, and right ventricular systolic function was assessed by echocardiography. RESULTS The patients had significant improvement in the transitional-dyspnea index after surgery (P<0.001). The mean (+/-SD) coefficient of retraction, an indicator of elastic recoil of the lung, improved (from 1.3+/-0.6 cm of water per liter before surgery to 1.8+/-0.8 after, P<0.001). Sixteen patients with increased elastic recoil had a greater increase in the distance walked in six minutes than the other four patients, in whom recoil did not increase (P=0.02). The improved lung recoil led to disproportionate decreases in residual volume as compared with total lung capacity (16 percent vs. 6 percent), but the decreases in both values were significant (P<0.001). Forced expiratory volume in one second increased (from 0.87+/-0.36 to 1.11+/-0.45 liters, P<0.001). End-expiratory esophageal pressure also decreased (P=0.002). These improvements in lung mechanics led to a decrease in arterial partial pressure of carbon dioxide form 42+/-6 to 38+/-5 mm Hg (P=0.006). Furthermore, the fractional change in right ventricular area, an indicator of systolic function, increased from 0.33+/-0.11 to 0.38+/-0.010 (P=0.02). CONCLUSIONS Lung-reduction surgery can produce increases in the elastic recoil of the lung in patients with diffuse emphysema, leading to short-term improvement in dyspnea and exercise tolerance.
E-cigarettes, vaping, and youth.

E-cigarettes, a relatively new product, storming the tobacco industry are causing a massive stir among public health advocates. While e-cigarettes have the potential to serve as an effective harm reduction tool for existing smokers, they also may present an equally tempting pathway to first time smoking, particularly among youth. Many fear that e-cigarettes will revive the popular smoking culture that has taken decades to dismantle. In April 2014, the FDA issued proposed rules to “deem” or extend its authority over tobacco products to regulate electronic cigarettes, cigars, pipe tobacco, nicotine gels, waterpipe (hookah) tobacco, and orally ingested dissolvable tobacco products. As proposed, FDA’s rules, among other things, would set a federal minimum age of 18 years to use e-cigarettes, require identification to purchase them (currently, just more than half of states impose age restrictions), prohibit most sales in vending machines, mandate warning labels on packaging, and prohibit manufacturers from providing free samples. Further, companies would be permitted to make claims for reduced risk only if the agency confirms the claim based on scientific evidence while also finding a benefit to the health of the public. While the proposed rules represent a watershed moment in tobacco control, they still leave major regulatory gaps affecting the most vulnerable population, youth. FDA’s silence when it comes to the use of flavored nicotine and marketing practices is certain to have negative consequences for youthful smokers. The agency should move boldly and rapidly to prevent companies from exploiting youth. By bolstering the proposed rules to limit advertising and prohibit flavored nicotine, the agency could prevent proliferation of e-cigarette use among adolescents, while not undermining its regulatory goal of reducing harm. The public health community must speak with a clear voice to urge meaningful and effective regulation to protect US youth against the reinvention of Big Tobacco.
The effect of desalivation on the malignant transformation of the tongue epithelium and associated stromal myofibroblasts in a rat 4‐nitroquinoline 1‐oxide‐induced carcinogenesis model

The aim of our study was to analyse desalivated rat tongue epithelium for histopathological changes, proliferating cell nuclear antigen (PCNA), and epithelium‐associated stromal myofibroblasts [SMF; α‐smooth muscle actin (αSMA)] following 0.001% 4‐nitroquinoline 1‐oxide (4NQO) administration in drinking water. Results were compared with those of identically treated but salivated specimens. 4NQO was administered for 7, 14, 22 and 28 weeks. Tongue length was divided into anterior, middle and posterior ‘thirds’. The histopathological changes per ‘third’ were scored as normal epithelium, hyperplasia, dysplasia, carcinoma‐in‐situ, and superficial and invasive carcinoma. The PCNA and αSMA stains were assessed by a point‐counting method. At all time points, the histopathological changes in the anterior and middle thirds were higher in the desalivated than in the salivated group (P < 0.05) but almost identical in the posterior third (P > 0.05). PCNA scores were significantly lower in the desalivated vs. the salivated group at almost all time points and tongue thirds (P < 0.05). SMF were usually scarce in both groups, but there was a significant surge in the posterior third at 28 weeks: the score in the desalivated group was only about one‐half that of the salivated group (P < 0.05). The absence of saliva seems to promote malignant transformation of the tongue epithelium in the early stages. PCNA cannot be regarded as a marker of proliferation and probably contributes to this process by other mechanisms. Emergence of SMF seems to be highly dependent on growth factors from saliva in addition to factors from cancerous cells.
Further characterization of IgE‐binding antigens in horse dander, with particular emphasis on glycoprotein allergens

IgE‐binding components in an extract of horse dander were analyzed, especially with regard to the glycoprotein allergens. After SDS‐PAGE under reducing conditions and blotting, several of the glycoprotein IgE‐binding components, including two distinct bands of 27 and 31 kDa, were detected. Together with several other bands, they were shown to bind to the lectins Sambucus nigra agglutinin (SNA) and Datura stramonium agglutinin (DSA), indicating terminal sialic acid linked α2→6 to galactose, and galactose linked β1→ 4 to N‐acetylglucosamine, respectively. Carbohydrate analysis after SDS‐PAGE and blotting showed the presence of mannose, galactose, N‐acetylglucosamine, and N‐acetyl neuraminic acid in the 27‐kDa band. The 14.4‐kDa glycoprotein component lost its IgE‐binding activity after periodate oxidation. Minor differences in allergenic activity in the other glycoprotein allergenic components were also detected, indicating that the carbohydrate part of the molecule seems to play a role in the IgE‐binding activity. Two‐dimensional electrophoresis and subsequent immunoblotting were performed to estimate the approximate number, molecular mass, and pI of IgE‐binding components. This resulted in a cluster of such components on the blot membrane.
Medical Control of Mass Gatherings: Can Paramedics Perform Without Physicians On-site?

Abstract Objective: Evaluate the experience of paramedic personnel at mass gatherings in the absence of on-site physicians. Design: Retrospective review of patients evaluated by paramedics with emergency medical services (EMS) medical control. Setting: First-aid facility operated by paramedics at an outdoor amphitheater involving 32 (predominantly rock music) concerts in accordance with the Chicago EMS System, June through September 1990. Participants: A total of 438 patients (≤0.1% on-site population) were evaluated. Interventions: Presentations to the first-aid facility were viewed as if the patient was presenting to an ambulance. Transportation to an emergency department was strongly recommended for all encounters. Time from presentation to the first-aid facility until disposition was limited to 30 minutes in the absence of on-line [direct] medical control. Refusal of care was accepted. On-line [direct] medical control with the EMS resource hospital was initiated as needed. Off-line [indirect] medical control consisted of weekly reviews of all patient records and periodic site visits. Results: Of the 438 patients, 366 (84%) refused further care, including 31 patients (7%) who refused advanced life support (ALS) level care. Seventy-two patients (16%) were transported; 37 by ALS and 35 by basic life support (BLS) units. On-line [direct] medical control was initiated in all ALS patients that were transported as well as for those who refused care. No known deaths or adverse outcomes occurred, based on lack of inquiries or complaints from the local EMS system, emergency departments receiving transported patients, law enforcement agencies, 9-1-1 emergency response providers, venue management, or security. No request for medical records from law firms have occurred. Problems noted initially were poor documentation and a tendency not to document all encounters (e.g., dispensing band-aids, tampons, earplugs, etc.). Concerns noted included: initial and subsequent vital signs, times of arrival, interventions, dispositions, and patient conditions of refusal. Specific problems with documentation of refusals at disposition included: appropriate mental status, speech, and gait; release with an accompanying family member or friend; and parental notification and approval of care for minors. There also was an initial tendency not to establish on-line [direct] medical control for ALS refusal or BLS medicolegal issues. Conclusions: The medical system configuration modeled after practices of prehospital care, demonstrates physicians did not need to be onsite when adequate EMS medical control existed with less than 30 minutes on-scene time.
Cytotoxic antibody reactivity in sera of melanoma patients against allogeneic and autologous cultured tumor cells and fibroblasts.

Using a complement-dependent microcytotoxicity assay, sera from melanoma patients were analyzed for antibody reactivity with cultured melanoma and normal adult skin fibroblasts. Sera from Stage I tumor-bearing patients prior to surgical excision, poor-prognosis Stage I and Stage II patients after tumor excision and lymphadenectomy but prior to adjuvant therapy, and normal individuals with a similar age and sex distribution were tested against a melanoma-fibroblast pair from an allogeneic donor. The groups displayed a wide range of cytotoxicity against both cell types, and no serum possessed melanoma-specific reactivity. Mean cytotoxicity of the Stage I tumor-bearing group was not significantly different ( p > 0.05) from that of the normal group for either target cell, and patients whose tumors went on to recur were not different from nonrecurrent patients. The Stage I and II postlymphadenectomy patients were not different from the normals in fibroblast reactivity. However, melanoma reactivity was significantly higher in the postlymphadenectomy patients than the normals ( p < 0.02). This was the result of an elevated reactivity in the patient population who remained disease free compared to patients whose tumors went on to recur ( p < 0.01), although a large overlap existed between these two groups. Cytotoxicity against autologous melanoma and fibroblasts was observed with sera obtained throughout the clinical course of four Stage II patients, and no melanoma-specific reactivity was detected. Absorption with cultured fetal fibroblasts of sera from Stage II patients both before and after immunotherapy with Bacillus Calmette-Guerin and allogeneic melanoma removed reactivity against allogeneic and autologous melanoma and adult fibroblasts. Therefore, the predominant antibody reactivity detected in these patients was directed against common fetal fibroblast-associated antigens, and no evidence was obtained for the presence of antibodies reactive with unique or shared tumor-specific antigens.
Normalization of multicolor fluorescence in situ hybridization (M‐FISH) images for improving color karyotyping

Multiplex or multicolor fluorescence in situ hybridization (M‐FISH) is a recently developed cytogenetic technique for cancer diagnosis and research on genetic disorders. By simultaneously viewing the multiply labeled specimens in different color channels, M‐FISH facilitates the detection of subtle chromosomal aberrations. The success of this technique largely depends on the accuracy of pixel classification (color karyotyping). Improvements in classifier performance would allow the elucidation of more complex and more subtle chromosomal rearrangements. Normalization of M‐FISH images has a significant effect on the accuracy of classification. In particular, misalignment or misregistration across multiple channels seriously affects classification accuracy. Image normalization, including automated registration, must be done before pixel classification.
Combinatorial Contextualization of Peptidic Epitopes for Enhanced Cellular Immunity

Invocation of cellular immunity by epitopic peptides remains largely dependent on empirically developed protocols, such as interfusion of aluminum salts or emulsification using terpenoids and surfactants. To explore novel vaccine formulation, epitopic peptide motifs were co-programmed with structural motifs to produce artificial antigens using our “motif-programming” approach. As a proof of concept, we used an ovalbumin (OVA) system and prepared an artificial protein library by combinatorially polymerizing MHC class I and II sequences from OVA along with a sequence that tends to form secondary structures. The purified endotoxin-free proteins were then examined for their ability to activate OVA-specific T-cell hybridoma cells after being processed within dendritic cells. One clone, F37A (containing three MHC I and two MHC II OVA epitopes), possessed a greater ability to evoke cellular immunity than the native OVA or the other artificial antigens. The sensitivity profiles of drugs that interfered with the F37A uptake differed from those of the other artificial proteins and OVA, suggesting that alteration of the cross-presentation pathway is responsible for the enhanced immunogenicity. Moreover, F37A, but not an epitopic peptide, invoked cellular immunity when injected together with monophosphoryl lipid A (MPL), and retarded tumor growth in mice. Thus, an artificially synthesized protein antigen induced cellular immunity in vivo in the absence of incomplete Freund's adjuvant or aluminum salts. The method described here could be potentially used for developing vaccines for such intractable ailments as AIDS, malaria and cancer, ailments in which cellular immunity likely play a crucial role in prevention and treatment.
Phylogeography of Sardinian Cave Salamanders (Genus Hydromantes) Is Mainly Determined by Geomorphology

Detecting the factors that determine the interruption of gene flow between populations is key to understanding how speciation occurs. In this context, caves are an excellent system for studying processes of colonization, differentiation and speciation, since they represent discrete geographical units often with known geological histories. Here, we asked whether discontinuous calcareous areas and cave systems represent major barriers to gene flow within and among the five species of Sardinian cave salamanders (genus Hydromantes) and whether intraspecific genetic structure parallels geographic distance within and among caves. We generated mitochondrial cytochrome b gene sequences from 184 individuals representing 48 populations, and used a Bayesian phylogeographic approach to infer possible areas of cladogenesis for these species and reconstruct historical and current dispersal routes among distinct populations. Our results show deep genetic divergence within and among all Sardinian cave salamander species, which can mostly be attributed to the effects of mountains and discontinuities in major calcareous areas and cave systems acting as barriers to gene flow. While these salamander species can also occur outside caves, our results indicate that there is a very poor dispersal of these species between separate cave systems.
