Cigarette smoke exposure and alveolar macrophages: mechanisms for lung disease

Cigarette smoking is the leading cause of preventable death worldwide. It causes chronic lung disease and predisposes individuals to acute lung injury and pulmonary infection. Alveolar macrophages are sentinel cells strategically positioned in the interface between the airway lumen and the alveolar spaces. These are the most abundant immune cells and are the first line of defence against inhaled particulates and pathogens. Recently, there has been a better understanding about the ontogeny, phenotype and function of alveolar macrophages and their role, not only in phagocytosis, but also in initiating and resolving immune response. Many of the functions of the alveolar macrophage have been shown to be dysregulated following exposure to cigarette smoke. While the mechanisms for these changes remain poorly understood, they are important in the understanding of cigarette smoking-induced lung disease. We review the mechanisms by which smoking influences alveolar macrophage: (1) recruitment, (2) phenotype, (3) immune function (bacterial killing, phagocytosis, proteinase/anti-proteinase release and reactive oxygen species production) and (4) homeostasis (surfactant/lipid processing, iron homeostasis and efferocytosis). Further understanding of the mechanisms of cigarette smoking on alveolar macrophages and other lung monocyte/macrophage populations may allow novel ways of restoring cellular function in those patients who have stopped smoking in order to reduce the risk of subsequent infection or further lung injury.
Enhancement of biomethane production from cattle manure with codigestion of dilute acid pretreated lignocellulosic biomass

ABSTRACT It is well known that dilute sulfuric acid pretreatment of the lignicellulosisc biomass is an effective approach used for the production of the ethanol. However, there are less studies on the biogas production from the pretreated lignocellulosics and hardly data available on the codigestion of cattle manure with the pretreated lignocellulosisc material. The aim of this study was to evaluate biomethane production potential of codigestion of cattle manure with dilute acid pretreated lignocellulosic biomass. Sugarcane bagasse and rice husk was pretreated with dilute sulfuric acid or phosphoric acid at 121°C for 20 minutes and subsequently subjected to anaerobic digestion alone or codigested with cattle manure. The results showed that codigestion of 1% phosphoric acid pretreated rice husk with cattle manure led to the highest methane production of 115 Nmlg−1VS while monodigestion of cattle manure and phosphoric acid pretreated rice husk produced 98 and 87 Nmlg−1VS, respectively. An inhibition was observed in anaerobic digestion of sulfuric acid pretreated rice husk and sugarcane bagasse during monodigestion and codigestion with cattle manure. The study concludes that dilute phosphoric acid pretreated lignocellulosics like sugarcane bagasse and rice husk can be used as a cosubstrate with cattle manure in anaerobic digestion for enhanced methane production. Dilute sulfuric acid pretreatment, which is effective method for the bioethanol production, causes inhibition during anaerobic digestion of the pretreated lignocellulosics.
Performance of Steers Fed Heated and (or) Ammoniated Endophyte Infected Fescue Hay1

Summary Effects of ammoniation, heating (100°C) and thermoammoniation (ammonia + heat) of endophyte-infected fescue hay (EIF) on average daily gain (ADG), daily consumption (DC), feed efficiency (FE), percentage body weight consumed (% BWC) and body temperature (BT) were evaluated for a 56 d period during July and September. Forty-eight Angus x Hereford steers averaging 207 kg body weight were randomly assigned to one of four treatment groups: 1) EIF control; 2) EIF + heat; 3) EIF + ammonia (NH3) and 4) EIF + heat + NH3. Steers were fed individually and hay was offered at a rate of 2.4% of shrunk body weight which was adjusted after 28 d. Feed consumption was recorded daily and individual rectal temperatures were taken bi-weekly. Steers were supplemented with . 9 4 kg ground shelled corn and a mineral mix was provided free choice. Average daily gain, DC, FE and % BWC was higher (P
Advice from a Seat at the Table: Exploring the Leadership Resilience Development of Black Women University Deans

In recent years, black women have begun to take more prominent university leadership roles at predominantly white institutions. Unfortunately, their progress is relatively slow, and their experiences have not garnered much historical attention in the university leadership literature. Hence, this study described the leadership resilience experiences of black women before becoming a university dean. The conceptual framework includes Black Feminist Thought and Constructivist Self-Development Theory which guide the two central research questions, how do black women describe their leadership resilience experiences before becoming a dean? And how do black women describe their leadership resilience experiences after becoming a dean? A qualitative methodology with a narrative study design encouraged eight black women university deans in the Southern United States to describe their experiences. Two data collection techniques, semistructured individual interviews and focus groups increased the validity of the results. The study found that most participants described their leadership resilience experiences as opportunities to engage in introspection, speak up, strive for personal growth, and utilize feedback. Participants also shared their definitions of leadership resilience. Kendra LewisStrickland *

HERZ SPACES AND POINTWISE SUM- MABILITY OF FOURIER SERIES

Abstract: A general summability method, the so-called θ-summability is considered for multi-dimensional Fourier series. It is proved that if the kernel functions are uniformly bounded in a Herz space then the restricted maximal operator of the θ-means of a distribution is of weak type (1, 1), provided that the supremum in the maximal operator is taken over a cone-like set. From this it follows that σ n f → f a.e. for all f ∈ L1(Td). Moreover, σ nf(x) converges to f(x) over a cone-like set at each Lebesgue point of f ∈ L1(Td) if and only if the kernel functions are uniformly bounded in a suitable Herz space. The Cesàro, Riesz and Weierstrass summations are investigated as special cases of the θ-summation.
Multinomial logistic regression model for assessing factors associated with body mass index of government employee of Gulariya Municipality, Nepal

Obesity has become very common and an increasing health burden worldwide in recent years. Nepal's increasing trend towards urbanization presents large health challenges and government employees are more vulnerable group which are facing obesity problems since they have to work long working hours by sitting. This study attempts to examine the prevalence of overweight and obesity; and factors associated with body mass index (BMI) in government employees of Gulariya municipality of Bardiya District, Nepal. A cross sectional study design was used and 248 respondents were selected using simple random sampling. Multinomial logistic regression model was adopted to assess the factors associated with BMI of government employees. Among the total 248 employees, prevalence of obesity, overweight and underweight were 12.9%, 27% and 10.1%. Among the factors, marital status (OR: 6.249, 95% CI: 1.432 to 27.273), diet habit (OR: 0.283, 95% CI: 0.085 to 0.949), alcohol consumption: no consuming (OR: 0.183, 95% CI: 0.037 to 0.913) and occasionally consuming (OR: 0.193, 95% CI: 0.040 to 0.943) have significant association with underweight. Similarly, designation gaggated (OR:2.559, 95% CI: 1.997 to 6.565), exercise (OR:2.336, 95% CI: 1.173to 3.422), diet habit (OR:2.425, 95% CI: 1.165 to 5.048) have significant association with overweight and designation gaggated (OR:16.513, 95% CI: 3.448 to 79.075), exercise (OR:0.078, 95% CI: 0.026 to 0.232), alcohol consumption : no consuming (OR:0.200, 95% CI:0.051 to 0.789) and occasionally consuming (OR: 0.206, 95% CI: 0.050to 0.848) have significant association with obese category.
Feitosa, M. F., & Levy, D. (2018). Novel genetic associations for blood pressure identified via gene-alcohol interaction in up to 570K

Heavy alcohol consumption is an established risk factor for hypertension; the mechanism by which alcohol consumption impact blood pressure (BP) regulation remains unknown. We hypothesized that a genome-wide association study accounting for gene-alcohol consumption interaction for BP might identify additional BP loci and contribute to the understanding of alcohol-related BP regulation. We conducted a large two-stage investigation incorporating joint testing of main genetic effects and single nucleotide variant (SNV)-alcohol consumption interactions. In Stage 1, genome-wide discovery meta-analyses in 131K individuals across several ancestry groups yielded 3,514 SNVs (245 loci) with suggestive evidence of association (P < 1.0 x 10−5). In Stage 2, these SNVs were tested for independent external replication in 440K individuals across multiple ancestries. We identified and replicated (at Bonferroni correction threshold) five novel BP loci (380 SNVs in 21 genes) and 49 previously reported BP loci (2,159 SNVs in 109 genes) in European ancestry, and in multi-ancestry meta-analyses (P < 5.0 x 10−8). For African ancestry samples, we detected 18 potentially novel BP loci (P < 5.0 x 10−8) in Stage 1 that warrant further replication. Additionally, correlated meta-analysis identified eight novel BP loci (11 genes). Several genes in these loci (e.g., PINX1, GATA4, BLK, FTO and GABBR2) have been previously reported to be associated with alcohol consumption. These findings provide insights into the role of alcohol consumption in the genetic architecture of hypertension.
Algebraic K-Theory and Quadratic Forms

The first section of this paper defines and studies a graded ring K . F associated to any field F. By definition, K~F is the target group of the universal n-linear function from F ~ x . • F ~ to an additive group, satisfying the condition that al • " ' x a, should map to zero whenever a i -q-a i + ~ = 1. Here F ~ denotes the multiplicative group F 0 . Section 2 constructs a homomorphism ~: K,F---, K~__I_~ associated with a discrete valuation on F with residue class field F. These homomorphisms ~ are used to compute the ring K, F(t) of a rational function field, using a technique due to John Tate. Section 3 relates K . F to the theory of quadratic modules by defining certain " Stiefel-Whitney invariants" of a quadratic module over a field F of characteristic . 2 . The definition is closely related to Delzant [-5]. Let W be the Witt ring of anisotropic quadratic modules over F, and let I c W be the maximal ideal, consisting of modules of even rank. Section 4 studies the conjecture that the associated graded ring
Mu-Gyeom Kim Failure Mode Analysis for Polymer EL Blue Devices’ Lifetime

We report failure mode observed in polymer EL blue devices, relating with life curve. The modes are analyzed by observing compositional and morphological variation using TEM-EDX, STM, and reverse engineering method as destructive ways, and also investigated mobility changes of hole and electron by measuring transient EL as a nondestructive way corresponding to life curve. We believe that the postulated failure modes in polymer EL devices can present right directions to obtain better performance, especially life time, of polymer devices in material and device structural designing points of view.
The Study on Thematic Structures of News Reports on the Coronavirus

Theme works together within a text to achieve coherence and it is a key terminology in written discourse analysis. Based on Halliday’s theories on the theme structures, the primary purpose of this paper is to explore the thematic structures of 13 news reports on the coronavirus abstracted from China daily. With combination of the quantitative and qualitative analysis, the results present that the distribution of simple themes are more frequent than the application of multiple themes and among simple themes nominal groups are most commonly adopted in clauses of the reports. Additionally, other thematic structures including adverbial groups, prepositional phrases, thematic equatives, thematised comments and existential there are also distributed in these news reports. It is of great value for readers to comprehend the written styles and the writer’s evaluation.
Clinical profile and bacteriological eitiology in cases of acute exacerbation of COPD in a tertiary care: a tertiary care study

Background: Acute exacerbation a prominent feature of COPD, is a major entity altering the course of the disease. These exacerbations are by complex interactions between host, bacteria, viruses and environment. Many studies done earlier indicate bacteria being the major cause of these exacerbations. This study is hence done to determine the bacteriological profile, haematological profile severity and grade clinical signs and symptoms based of ‘Gold’ criteria. Methods: A cross sectional descriptive study, done on a total of 80 cases for a period of 18 months on patients admitted to Sathya Sai medical college with acute exacerbations of chronic obstructive pulmonary disease. Cases of acute exacerbation of COPD satisfying the eligibility criteria were included in the study. Clinical and microbiological parameters were noted with special preference to sputum culture and spirometry. Results: Bacteria was not present in 46 (57.5%) of the study population. Klebsiella pneumoniae was present in 12 cases (15.0%), pseudomonas aeruginosa in 6 (7.5%), staphylococcus aureus in 6 (7.5%), streptococcus pneumoniae in 5 (6.2%) and actinobacter in 5 (6.2%). 34 cases were sensitive to antibiotics (52.5%). Majority being sensitive to ceftriaxone, piperacillin and levofloxacillin. 43 cases belonged to ‘Gold’ criteria on spirometry. Hyper inflated lung, tubular heart was present in 39 (48.8%) cases. With normal chest X-ray findings in the rest. Conclusions: Bacteria causing exacerbations is different in India as compared to other studies from different countries. Klebsiella pneumonia being most common organism followed by Pseudomonas aeruginosa, Staphylococcus aureus, Streptococcus pneumoniae and actinobacter. AECOPD patients with bacteria showed sensitivity to ceftriaxone, piperacillin and levofloxacillin. Hence, these etiology with sensitivity pattern should be kept in mind for starting a patient on empirical antibiotic therapy.
RESEARCH OF RADIOISOTOPE PRODUCTION WITH FAST NEUTRONS. VI. PREPARATION OF Cu-67

Copper-67, the longest-lived radioisotope of copper, was prepared by using the reaction 67Zn(n p,)67Cu. Zinc enriched in 67Zn up to 93.4% was irradiated in JRR-1 reactor for 5hr with a fast neutron flux of 1.5×1012n/cm2/sec. Copper-67 formed in the zinc target was separated by anion exchange separation using the chloro-complex of the metals. The yield of 67Cu and radiochemical impurity were investigated. Seventeen millimicrocuries of 67Cu was obtained from 1mg of zinc. No radioactive impurities other than 64Cu were not found. Even with the use of enriched target, a more MCu was produced than 67Cu. The proportion of 67Cu to total copper radioactivity was 26% immediately after the irradiation.

Protective effects of resveratrol on kidney function tests and renal histopathology in carbon tetrachloride-induced renal toxicity in rats

In this study, it was aimed to investigate the protective effect of Resveratrol, which has a strong antioxidant effect on kidney tissues of rats experimentally induced with carbon tetrachloride with nephrotoxicity, by kidney function tests and histopathology. For this purpose, 32 male Wistar Albino rats were used. The subjects were randomly selected, 1st group control, 2nd group CCl4, 3rd group Resveratrol. The 4th group was divided into 4 groups as CCl4 + Resveratrol. At the end of the experiment, animals were sacrificed under anesthesia and kidney samples were taken in 10% formalin solution for histopathological analysis. In the histopathological examination, it was found that the rats in the control and Resveratrol groups had normal kidney histological structure. In CCI4 group, severe hydropic degeneration in tubules epithelium, mild coagulation necrosis in tubules epithelium and severe hyperemia in the vessels were observed. When kidney tissues of rats were examined in CCI4 + Resveratrol group, mild hydropic degeneration in tubules epithelium and mild hyperemia in vessels were observed. When the kidney tissues of the rats in the Resveratrol group were examined, it was observed that they had a normal histological appearance. As a result, it was determined that Resveratrol has a protective effect on kidney damage caused by CCI4.

Effects of various chemical treatments on physicochemical properties of cotton shell fibers –A study

The hydrophilic characteristic of natural fibers was mostly caused due to the existence of hemicellulose and lignin contents which are diminished by carrying out various chemical treatments. The adhesion property and mechanical properties are enhanced due to the chemical treatments. The optimally alkali treated Cotton Shell Fibers (CSFs) were subjected to chemical modifications by using Benzoyl Chloride, Potassium Permanganate, Stearic Acid and Zinc Chloride. From the alkaline treatment, 5 % (w/v) NaOH solution with 60 minutes soaking time was established as optimum. In continuation with alkali treatment, chemical modifications were done and the thermal analysis, X-Ray Diffraction (XRD) and Fourier Transform Infrared (FTIR) spectroscopy reports confirm positive changes in the physicochemical properties of CSFs and also successful elimination of amorphous and wax contents.
A new application of Poisson Equation: Image Enhancement

Poisson equation has tremendous amount of scope and has been used in several engineering applications. It found its way in image processing application too. Some interesting works are shape analysis; image matching, image compositing, image smoothing, image editing, image matting and image simulation for mimicking object deformation. In this article, we are proposing a brand new application in image processing field. We have explored the capability of Poisson’s equation on enhancing images. The performance was examined through Berkeley images in terms of qualitative and quantitative analysis. Performance of this work has been measured by statistical features like Probabilistic Rand Index (PRI), Global Consistency Error (GCE), Variation of Information (VOI). Our proposal scored a PRI measure of 0.83512, GCE of 0.0324 and VOI of 0.76521over the traditional histogram equalization (HE) method which scored the PRI about 0.64756, GCE about 0.03548 and VOI about0.8484. With this proposal we have successfully introduced a new application for poisson’s equation successfully.
