Clinicopathological studies on the antioxidant effect of barley on chicken affected by lead toxicities.

Forty five, 21-day-old balady chick were used in this experiment. Chicks were divided into three equal groups. The 1 group used as control. The 2 and 3 groups were supplemented with lead (Pb) acetate (1500 ppm) in drinking water but the latter group received ration containing 20% barley. Blood samples were collected from the wing vein after 1, 2 and 3 weeks. RBCs count Hb concentration and PCV were significantly decreased in group II during the experimental period. RBCs indices showed a significant decrease in MCH and MCHC in group II after 2 and 3 week of experiment. Leukogram showed heteropenia and moncytopenia. Total protein values showed significant decrease in group II due to decrease in serum albumin level after 2 and 3 week of experiment. Significant increase in activity of liver enzymes AST & ALT and serum uric acid were observed in group II after 3 weeks of experiment. Measurement of serum level of malondialhyde (MDA) revealed a significant increase in group II after 2 weeks of experiment while the total antioxidant capacity (TAO) showed significant decrease in group II after 2 and 3 weeks of experiment. Results of the lead residues in the experimental groups revealed that lead residue in muscle, liver and kidney were rise in group II compared with groups I and III.
Growth of Lodgepole Pine Stands and Its Relation to Mountain Pine Beetle Susceptibility

Periodic diameter and basal area growth were determined for partially cut stands of lodgepole pine at five locations over approximately 10 year periods. After cutting, average diameters in the partially cut plots generally increased by 0.8 inches or more, while average diameter in the uncut controls increased by 0.6 inches or less. Diameter growth in the partially cut plots was generally significantly greater than diameter growth in the controls. Individual tree growth is discussed in relation to potential susceptibility to mountain pine beetle infestation. Basal area decreased in three of the four GSL (growing stock level) 40 stands because of windthrow. Basal area generally increased >1.0 ft2/ acre/year in partially cut plots except in the GSL 40 stands with substantial windthrow and one GSL 100 with an Armillaria infection pocket. Basal area increases in the control plots ranged from 0.2 to 1.1 ft2/acre/year, although the one control with a BA growth rate of 1.1 ft2/acre/year had a relatively low initial BA. Data from the stands are employed in the susceptibility rating methods of Amman et al. (1977), Shore and Safranyik (1992), and Anhold et al. (1996) to determine stand susceptibility and the results discussed in terms of general applicability of these methods to partially cut stands. Basal area growth is used to estimate the length of time required for various stand densities to reach specific susceptibility thresholds for mountain pine beetle infestation. Several of the GSL 40 stands are not projected to reach the susceptibility thresholds in <100 years because of windthrow. Barring mortality >1%, GSL 80 stands are estimated to reach the basal area threshold of 120 ft2 per acre in <25 years. GSL 120 stands, essentially at the basal area 120 threshold, are generally projected to reach the basal area threshold of 150 ft2 per acre in <35 years.
PROJECTIVE BUNDLES OVER SMALL COVERS AND THE BUNDLE TRIVIALITY PROBLEM

This paper investigates the projective bundles over small covers. We first give a necessary and sufficient condition for the projectivization of a real vector bundle over a small cover to be a small cover. Then associated with moment-angle manifolds, we further study the structure of such a projectivization as a small cover by introducing a new characteristic function on simple convex polytopes. As an application, we characterize the real projective bundles over 2-dimensional small covers by interpreting the fibre sum operation to some combinatorial operation. We next study when the projectivization of Whitney sum of the tautological line bundle and the tangent bundle over real projective space is diffeomorphic to the product of two real projective spaces.
PERSONAL TIME CAPITAL IN THE DIGITAL SOCIETY: AN ALTERNATIVE LOOK AT SOCIAL STRATIFICATION AMONG THREE GENERATIONS OF HIGHLY SKILLED PROFESSIONALS IN ESTONIA

This article aims at analysing how highly educated professionals cope with technological and social acceleration. To explore the emerging patterns of time-based stratification we use an empirical model of personal time-use capability based on the data from a representative survey conducted in 2014 among the Estonian population aged 15–79 (N=1,503) and focus groups conducted in 2017–2018 among three generations of academic professionals (n=24). The mixed-method analysis revealed a multidimensional pattern of socio-demographic, life-course and agency-related factors influencing individual time-use capability and the related set of practices and attitudes. Our findings confirm the assumed importance of age-related factors: the youngest professionals (born 1989–1994) tend to be most flexible, and the middle-aged (born 1969–1974) most efficient, in developing timeuse strategies to cope with social acceleration, while the oldest (born 1949–1954) win the least from rapid developments. In general, highly educated professionals collectively serve as agents of social acceleration.
Differential Privacy for Machine Learning

Machine learning algorithms can leak private information contained in particular training data. Differential privacy ensures that an algorithm does not rely too strongly on any individual data point. Differentially private machine learning can be achieved by injecting noise in the training process. In particular, the privacy of DP-SGD has already been well-studied, yet only in the case where each training example is sampled with replacement. We focus on the more practical case of sampling without replacement, or shuffling, and try to provide privacy guarantees for this algorithm. We also explore possible relaxations of differential privacy.
The Electronic Transport Channel Protection and Tuning in Real Space to Boost the Thermoelectric Performance of Mg3+δSb2-yBiy near Room Temperature

The optimization of thermoelectric materials involves the decoupling of the transport of electrons and phonons. In this work, an increased Mg1-Mg2 distance, together with the carrier conduction network protection, has been shown as an effective strategy to increase the weighted mobility (U = μm∗3/2) and hence thermoelectric power factor of Mg3+δSb2-yBiy family near room temperature. Mg3+δSb0. 5Bi1.5 has a high carrier mobility of 247 cm2 V−1 s−1 and a record power factor of 3470 μW m−1 K−2 at room temperature. Considering both efficiency and power density, Mg3+δSb1. 0Bi1.0 with a high average ZT of 1.13 and an average power factor of 3184 μW m−1 K−2 in the temperature range of 50-250°C would be a strong candidate to replace the conventional n-type thermoelectric material Bi2Te2.7Se0. 3. The protection of the transport channel through Mg sublattice means alloying on Sb sublattice has little effect on electron while it significantly reduces phonon thermal conductivity, providing us an approach to decouple electron and phonon transport for better thermoelectric materials.

Canadian Cannabis Consumption and Patterns of Congenital Anomalies: An Ecological Geospatial Analysis

Supplemental Digital Content is available in the text Objectives: Cannabis is a known teratogen. Data availability addressing both major congenital anomalies and cannabis use allowed us to explore their geospatial relationships. Methods: Data for the years 1998 to 2009 from Canada Health and Statistics Canada was analyzed in R. Maps have been drawn and odds ratios, principal component analysis, correlation matrices, least squares regression and geospatial regression analyses have been conducted using the R packages base, dplyr, epiR, psych, ggplot2, colorplaner and the spml and spreml functions from package splm. Results: Mapping showed cannabis use was more common in the northern Territories of Canada in the Second National Survey of Cannabis Use 2018. Total congenital anomalies, all cardiovascular defects, orofacial clefts, Downs syndrome and gastroschisis were all found to be more common in these same regions and rose as a function of cannabis exposure. When Canada was dichotomized into high and low cannabis use zones by Provinces v Territories the Territories had a higher rate of total congenital anomalies 450.026 v 390.413 (O.R. = 1.16 95%C.I. 1.08-1.25, P = 0.000058; attributable fraction in exposed 13.25%, 95%C.I. 7.04–19.04%). In geospatial analysis in a spreml spatial error model cannabis was significant both alone as a main effect (P < 2.0 × 10−16) and in all its first and second order interactions with both tobacco and opioids from P < 2.0 × 10−16. Conclusion: These results show that the northern Territories of Canada share a higher rate of cannabis use together with elevated rates of total congenital anomalies, all cardiovascular defects, Down's syndrome and gastroschisis. This is the second report of a significant association between cannabis use and both total defects and all cardiovascular anomalies and the fourth published report of a link with Downs syndrome and thereby direct major genotoxicity. The correlative relationships described in this paper are confounded by many features of social disadvantage in Canada's northern territories. However, in the context of a similar broad spectrum of defects described both in animals and in epidemiological reports from Hawaii, Colorado, USA and Australia they are cause for particular concern and indicate further research.
Academically Oriented Activity Breaks for First-Grade Chilean Students: Development and Pilot Testing Effectiveness

We developed and pilot tested the effectiveness of a physically active academic program, Active Breaks (AB), whose objective is to increase school time moderate/vigorous physical activity (MVPA) among first graders, through daily 15-minute bouts of MVPA, at the beginning of the first lesson. Initially, 240 cards including one game each were developed and tested in first-grade students from 16 schools in Santiago. Trained observers and school teachers assessed the time, ease, and feasibility of implementation for each card. Barriers and facilitators to implementation were obtained from semistructured interviews to 14 teachers (out of 16). In eight schools (n = 556 students), we compared school time MVPA (with accelerometers) at baseline and follow-up, using test of proportions. One-hundred and twenty cards (games) complied with all aspects. AB were implemented 50% of the time with a duration of 14 minutes (SD = 5). More than 90% of the time, teachers felt competent to conduct AB, and children understood the instructions and enjoyed the activity. The main facilitators included teachers liking physical activity and considering it important, support of principal and school staff, and conducting AB inside the classroom. Barriers included teacher’s workload and having to conduct AB during the first lesson. During the 4-month period of implementation, MVPA increased by 1.5 and 1.2 percentage points in boys and girls, respectively. The set of 120 cards is easy and feasible to implement. Moreover, preliminary results suggest they could be effective in increasing MVPA during school time, although studies with longer follow-ups are needed to assess the validity of these findings.
Parametrization of multi-energy CT projection data with eigentissue decomposition

The purpose of this work is, firstly, to propose an optimized parametrization of the attenuation coefficient to describe human tissues in the context of projection-based material characterization with multi-energy CT. The approach is based on eigentissue decomposition (ETD). Secondly, to evaluate its benefits in terms of accuracy and precision of radiotherapy-related parameters against established parametrizations. The attenuation coefficient is parametrized as a linear combination of virtual materials, eigentissues, obtained by performing principal component analysis on a set of reference tissues in order to optimally represent human tissue composition. Two implementations of ETD are compared with other pre-reconstruction formalisms established for dual-energy and photon-counting CT in a simulation framework. The first implementation uses a single set of eigentissues to describe all human tissues, while the second uses different sets of eigentissues to characterize soft tissues and bones, and includes a post-reconstruction classification step. The simulation framework evaluates the reconstruction accuracy of various radiotherapy-related quantities over a range of 71 human tissues for various noise levels. Compared to conventional parametrizations, the first implementation of ETD reduces the mean error and root-mean-square error (RMSE) in two radiotherapy-related quantities (the proton stopping power and the mass energy absorption coefficient of 21 keV photons from 103Pd seeds used in brachytherapy) for all noise levels and modalities investigated. This illustrates that a decomposition basis selected with principal component analysis is superior to an arbitrary pair of materials to describe human tissues. The mean error on radiotherapy-related parameters can be further reduced with the classification-based approach. In the context of pre-reconstruction material characterization with multi-energy CT, parametrizing the attenuation coefficient with eigentissues provides a more accurate and precise evaluation of human tissues properties for radiotherapy. Accurate quantification can thus be achieved without the need to parametrize tissues using unphysical parameters, such as the energy-dependent effective atomic number.
Impact of glaucoma on executive function and visual search

Executive function and visual search are linked to a number of activities of daily living including driving and mobility. Using a computerised version of the Trail Making Test B (TMT‐B), we compared the executive function and visual search ability of older adults with glaucoma to age‐similar controls and identified which visual function tests best predict TMT‐B performance. Novel low‐contrast and shifting‐target variations of the test were incorporated to explore the effects of different levels of test complexity.
Vitamin B12 Deficiency in Diabetic Patients on Metformin Therapy

Objectives This study aimed to determine the prevalence of vitamin B12 deficiency amongst diabetic patients on metformin therapy. Methods This cross-sectional study was conducted at general clinics at the University Health Center and diabetes outpatient clinics at Sultan Qaboos University Hospital, Muscat, Oman, between January and December 2017. All Omani adults who were diagnosed with type 2 diabetes mellitus and took metformin were invited to participate in the study. The variables included in this study were age, gender, duration of diabetes, dose and duration of metformin therapy, haemoglobin and glycosylated haemoglobin level. Results A total of 248 subjects were included (response rate = 95.4%) of which 26 (10.5%) were vitamin B12 deficient and 53 (21.4%) were borderline deficient. The mean daily dose of metformin was highest among vitamin B12 deficient group (1,981 ± 222 mg; P = 0.004). Conclusion The prevalence of vitamin B12 deficiency is considerable among diabetic patients on metformin therapy. Further research is needed to confirm the need for routine screening and monitoring.
Analysis of clinical features and prognostic factors of lung cancer patients: A population-based cohort study.

OBJECTIVES This paper analyzes clinical features of lung cancer patients and discusses factors influencing lung cancer occurrence and prognosis. METHODS Patients diagnosed with lung cancer from 1975 to 2016 are analyzed based on SEER database. The samples are divided into groups according to the number of positive lymph nodes of LN>3 and LN≤3. Univariate and multivariate Cox risk models are performed. After balancing the clinicopathological features of the two groups with the propensity score matching (PSM) method, the survival rates of the two groups are compared. RESULTS A total of 30,864 patients are included in this study. Kaplan-Meier curves show that the survival rate of patients with LN≤3 is higher than that of patients with LN>3 (p < 0.0001). Univariate and multivariate Cox proportional risk model analysis suggests that the number of lymph nodes is an independent prognostic risk factor for lung cancer. LN≤3 group shows better OS (HR2.066; 95% CI 1.941-2.199, p<0.01) and better CSS (HR 2.461; 95% CI 2.304-2.629, p<0.01). In addition, age at diagnosis, gender, Laterality, Derived AJCC T, 7th ed (2010-2015), Derived AJCC N, 7th ed (2010-2015), and Derived AJCC M, 7th ed, 2010-2015) have also been proved to be potential prognostic factors. A total of 1,851 pairs of patients are screened after 1:1 PSM matching. Patients with LN≤3 have significant improvements in OS and CSS ((HR 1.09; 95% CI 1.001-1.187, p<0.05 and HR 1.127; 95% CI 1.03-1.232, p<ß0.001). CONCLUSION The number of lymph nodes is an independent prognostic risk factor for lung cancer. Patients with fewer lymph node positives have a better survival prognosis than patients with more lymph nodes.
Imaging findings on contrast-enhanced ultrasound, magnetic resonance imaging and hybrid positron emission tomography in Takayasu arteritis: a case report.

This case report demonstrates the potential of contrast-enhanced ultrasound (CEUS) in diagnosing active arterial wall inflammation in a symptomatic patient with Takayasu arteritis (TA). To our knowledge, this is the first case which demonstrates pictorial correlation of arterial wall neovascularity on CEUS with mural edema on magnetic resonance imaging and metabolic activity on positron emission tomography - computed tomography in the same patient. As TA is a chronic disease which requires long-term follow-up, CEUS could be the potential imaging modality of choice as it is radiation-free, non-nephrotoxicand easily available.
Effect of Protective Equipment on Firefighters' External and Internal Workloads During a Simulated Rescue Intervention

Abstract Marcel-Millet, P, Ravier, G, and Groslambert, A. Effect of protective equipment on firefighters' external and internal workloads during a simulated rescue intervention. J Strength Cond Res 36(8): 2291–2297, 2022—Firefighter's protective equipment is one of the main factors increasing psychophysiological demand during rescue intervention. Workload quantification defines the amount of stress placed on an individual. This study aimed to test the relationships and compare different workload methods to discriminate 3 protective equipment conditions based on simulated rescue intervention. The protective equipment was (a) personal protective clothing (PPC); (b) PPC and a self‐contained breathing apparatus (SCBA), including a cylinder, a full‐face piece, and a breathing regulator; and (c) PPC and only the cylinder of the SCBA (SCBAc). Workload was determined using methods based on heart rate (HR), perceived exertion (sRPE), acceleration, and an indirect method based on postexercise HR variability. Differences between conditions were analyzed with repeated-measures analyses of variance. Relationships between workload methods were determined using Pearson's correlations. Statistical significance was set at p < 0.05. The HR-based and sRPE methods showed higher values in the SCBA and SCBAc conditions than the PPC condition (p < 0.0001); only the sRPE method had a higher workload for the SCBA condition than the SCBAc condition (p < 0.0001). Acceleration-based workloads were lower in the SCBA and SCBAc conditions than the PPC condition (p < 0.0001). The indirect method revealed no difference between the 3 conditions. Significant relationships were observed between the HR-based and sRPE methods (r = 0.544–0.738). Inverse significant correlations were observed between the HR-based and sRPE methods and the acceleration workload methods (r = −0.319 to −0.762). Although HR-based and sRPE methods might quantify the workloads, the sRPE method was more sensitive to discriminate between the SCBAc and SCBA conditions.
Sexuality education delivery in Australian regional secondary schools: A qualitative case study

Background: Factors affecting the delivery of sexuality education to school students include government policy, school leadership and teacher confidence. Objective: The aim of this paper was to understand, from the perspective of regional education, health and welfare sector professionals, what is needed to support good sexual health for secondary school students. Methods: A qualitative study that took place in ‘Fairview’, a regional location in Victoria, Australia. Five focus groups, totalling 37 participants, were conducted in 2015. An inductive analysis was used to identify key themes. Findings: The main theme was the inconsistent presence and delivery of sexuality education curriculum in Fairview schools. This was attributed to factors such as perceived lack of commitment at government level to sexuality education, lack of importance in comparison with other subjects and variation in inclusion across year levels. Teachers and the delivery of sexuality education and the role of school leadership in supporting sexuality education were the two sub-themes present within the broader narrative. Teacher capacity to deliver sexuality education was ascribed to lack of training. Perceptions concerning the use of external providers to deliver sexuality education differed, as did opinions about the role of school leadership in supporting sexuality education. Conclusion: Sexuality education in schools could be improved through clearer government policy direction. This would signal the importance of sexuality education to school leaders and, if supported via resources such as training for teachers, could assist in achieving the aim of improving students’ sexual health and well-being.
Systematic Review of Aortic Dissection Detection Risk Score Plus D‐dimer for Diagnostic Rule‐out Of Suspected Acute Aortic Syndromes

In patients at low clinical probability of acute aortic syndromes (AASs), decision on advanced aortic imaging is cumbersome. Integration of the aortic dissection detection risk score (ADD‐RS) with D‐dimer (DD) provides a potential pipeline for standardized diagnostic rule‐out. We systematically reviewed and summarized supporting data.
