Aim: To accurately determine the reliability of pallor on the dorsal surface of tongue and/or palpebral conjunctiva to diagnose anaemia in middle aged female patients, by using haemoglobin as the reference standard. To correlate pallor with different grades of anaemia according to WHO criteria. Objective: A cost effective chair side clinical observation of pallor to diagnose anaemia in middle aged female patients and to provide counselling thereby reducing the prevalence of anaemia and its associated morbidities, especially in poor resource setting. Method: Between 1st June 2022 to 30th Aug 2022, all female dental outpatients between 40-65 years of age were prospectively examined. Among these subjects,100 female patients with pallor on the dorsal surface of tongue and/or palpebral conjunctiva who met the specified inclusion and exclusion criteria, provided informed consent, and who had undergone blood test within one day of clinical pallor detection were enrolled in the study. Based on haemoglobin levels, anaemia was divided into mild, moderate, and severe according to WHO criterion (Hb: <12g/dl). Anaemia was divided into mild (Hb: 11-11.99 g/dl), moderate (Hb: 7-10.99 g/dl), and severe (Hb: < 7g/dl). Data was expressed as frequency and percentages. Result: In the present study, 82% of subjects with either conjunctival pallor or tongue pallor or both were anaemic with laboratory proven haemoglobin levels < 12 g/dl which was found to be statistically significant. 14.6% subjects were diagnosed with mild anaemia, 51.2% with moderate anaemia, and 34.1% with severe anaemia. Among patients with mild and moderate anaemia, conjunctival pallor out performed tongue pallor whereas in subjects with severe anaemia, tongue pallor outperformed conjunctival pallor.
Detecting pallor in a female patient is a dependable sign of anaemia. Furthermore, identifying tongue surface pallor is a strong signal of severe anaemia in female patients whereas conjunctival pallor is a good indicator for mild and moderate anaemia. The effective implementation of dietary counselling has the potential to significantly reduce the prevalence of anaemia.

Published: April 2012

AbstractBiocompatible polymer blends, such as alginate blends, have a widespread use in pharmaceutical and medical applications due to their specific features, such as biodegradation, adhesiveness, and thermo‐ and pH sensitivity and that can be obtained from the mixture composition. In this work, the use of alginate blends was tested in a novel production methodology of therapeutic dosage forms based on polymeric chain reticulation phenomena induced by exposure to bivalent ions. Two kinds of sodium alginate were used to obtain gel films (structured films) in blends with Pluronic F127®. The blends were considered for applications in gel paving of drug‐eluting stents. Sodium alginate was also used in shell–core particle production (structured particles) to obtain shell‐barrier reducing drug release in the preparative steps (see wash operations). Both structures, films and particles, were obtained using Cu2+ and Ca2+ ions, respectively. Film/shell barrier properties were tested in dissolution experiments using vitamin B12 as an active molecule model. Experimental work demonstrated that the alginate composition is a crucial point in defining reticulated structures. © 2012 Wiley Periodicals, Inc.

AbstractAtomic layer deposition (ALD) of Al2O3 is applied on a polypropylene separator for lithium‐ion batteries. A thin Al2O3 layer (<10 nm) is coated on every surface of the porous polymer microframework without significantly increasing the total separator thickness. The thin Al2O3 ALD coating results in significantly suppressed thermal shrinkage, which may lead to improved safety of the batteries. More importantly, the wettability of Al2O3 ALD‐coated separators in an extremely polar electrolyte based on pure propylene carbonate (PC) solvent is demonstrated, without any decrease in electrochemical performances such as capacity, rate capability, and cycle life. Finally, a LiCoO2/natural graphite full cell is demonstrated under extremely severe conditions (pure PC‐based electrolyte and high (4.5 V) upper cut‐off potential), which is enabled by the Al2O3 ALD coating on all three components (cathode, anode, and separator).

Published: April 2012

AbstractBackgroundIn Malaysia, surveillance of fatal occupational injuries is fragmented. We therefore analyzed an alternative data source from Malaysia's Social Security organization, the Pertubuhan Keselamatan Sosial (PERKESO).MethodsWe conducted a secondary data analysis of the PERKESO database comprised of 7 million employees from 2002 to 2006.ResultsOverall, the average annual incidence was 9.2 fatal occupational injuries per 100,000 workers. During the 5‐year period, there was a decrease in the absolute number of fatal injuries by 16% and the incidence by 34%. The transportation sector reported the highest incidence of fatal injuries (35.1/100,000), followed by agriculture (30.5/100,000) and construction (19.3/100,000) sectors. Persons of Indian ethnicity were more likely to sustain fatal injuries compared to other ethnic groups.ConclusionsGovernment and industry should develop rigorous strategies to detect hazards in the workplace, especially in sectors that continuously record high injury rates. Targeted interventions emphasizing worker empowerment coupled with systematic monitoring and evaluation is critical to ensure success in prevention and control measures. Am. J. Ind.

Malignant mesothelioma incidence among talc miners and millers in New York State
Authors: Finkelstein Murray M. 
Published: April 2012

AbstractBackgroundThere is controversy about the potential for dust from the talc mines and mills of New York State to cause mesothelioma. Honda et al. published a study of mortality among New York talc workers and concluded that it was unlikely that the two deaths from mesothelioma were caused by talc ore dust. However, fibers of tremolite and anthophyllite have been found in the lungs of talc workers and Hull concluded that “New York talc exposure is associated with mesothelioma, and deserves further public health attention.”MethodsData concerning additional cases of mesothelioma in the cohort have been posted by NIOSH. I used information from the NIOSH website and the Honda report to analyze the incidence of mesothelioma during the years 1990–2007.ResultsThere were at least five new cases of mesothelioma in the cohort and mesothelioma incidence rates were at least five (1.6–11.7) times the rate in the general population (P < 0.01).ConclusionsI conclude that: (1) mesothelioma has been diagnosed among members of the cohort at a rate in excess of that in the general population; (2) fibers of tremolite and anthophyllite have been detected in dust and the lungs of talc workers; and (3) these fibers are known causes of mesothelioma. It is prudent, on the balance of probabilities, to conclude that dusts from New York State talc ores are capable of causing mesothelioma in exposed individuals. Am. J. Ind.

AbstractBackgroundProfessional cleaning has emerged as a new industry in Taiwan in the past few years. However, information about the workload and prevalence of musculoskeletal disorders (MSDs) among these workers is still limited. This study investigated the prevalence of musculoskeletal discomforts and the characteristics of musculoskeletal activities of cleaning workers in Taiwan.MethodsFace‐to‐face interviews to collect basic information and to administer the Chinese version of the Standardized Nordic Musculoskeletal Questionnaire were conducted on 180 cleaners. Biaxial electrogoniometers and electromyography were used to characterize the motion and forceful exertion of 56 cleaners during work.ResultsNearly 90% of the participants reported musculoskeletal discomfort in at least one body part due to work. Of the nine body parts examined, hand/wrist (41.7%), shoulder (41.1%), low back (37.8%), and elbow (33.3%) were most frequently reported to exhibit discomfort. Additionally, time pressure as a psychosocial risk factor was found to be associated with discomfort in several body parts. Measurements of electrogoniometry showed that wrists of many cleaners were frequently held in extreme angles of ulnar/radial deviation, leading to an increased risk of developing carpal tunnel syndrome. Motion repetitiveness and force output during mopping and sweeping tasks were considered less influential in developing hand/wrist discomfort.ConclusionsCleaners in Taiwan are a high‐risk group for developing MSDs, and solutions are needed to avoid extreme motion angles of the wrists when performing cleaning tasks. Moreover, both psychosocial stress and the welfare of this group of workers deserve immediate attention from management and the government. Am. J. Ind.

Effect of adding polysilane on melt‐flow properties of ultra‐high molecular weight PE
Authors: Katsuhisa Tokumitsu , Aiko Iguchi , Shigeya Nakamura , Masahiro Yamada , Mika Nakamura , Kana Kobori 
Published: April 2012

AbstractThe effects of polysilane addition on the melt‐flow and mechanical properties of ultra‐high molecular weight polyethylene (UHMWPE) were investigated. The kneading torque during melt process of pure UHMWPE without polysilane increased significantly with time and reached a constant value after 100 min. However, the kneading torque did not increase by addition of polysilane materials into UHMWPE, which indicates that all the polysilane materials suppress an increase in the kneading torque during melt process of UHMWPE at 200°C, especially a linear polysilane (PMPS) and a networked structure polysilane (PPSi). When using linear polysilane materials with different molecular weights, the low molecular weight polysilane (PM‐5, Mw = 500 Da) had the most dominant effect on the heat‐flow and mechanical properties of UHMWPE. UHMWPE with PM‐5 could be elongated over 1000% strain, which was the similar to the case for pure UHMWPE, although the elongation at break of UHMWPE with additions of different molecular weight PMPS was significantly decreased with increasing molecular weight of PMPS. Furthermore, the kneading torque during melt process of UHMWPE decreased with increase in the amount of PM‐5 addition, from 1 to 5 wt %. © 2012 Wiley Periodicals, Inc. J Appl Polym Sci, 2012

Published: April 2012

AbstractSeveral epoxy difunctional hybrid alkylene‐silicone telomers with different silicone characters and organic spacers (linkers) were prepared via the platinum‐catalyzed polyhydrosilylation of α,ω‐dihydrosiloxanes and α,ω‐dienes. Thereafter, the resulting SiH‐terminated prepolymers were terminally functionalized with 4‐vinyl‐1,2‐epoxycyclohexane or allyl glycidyl ether. In the presence of a lipophilic cationic photoinitiator, the terminally epoxy‐functionalized hybrid alkylene–silicone telomers were photopolymerized to give crosslinked, soft, elastomeric, and transparent films. The progress of the photoinitiated cationic ring‐opening epoxide polymerizations was monitored using optical pyrometry. Potential applications for these novel photocurable epoxy‐functional telomers are as modifiers for UV curable coatings, printing inks, adhesives, and release coatings. © 2012 Wiley Periodicals, Inc.

Nonisothermal melt crystallization kinetics of syndiotactic polypropylene/alumina nanocomposites
Authors: Truong Le Thuy , Larsen Åge , Holme Børge , Roots Jaan 
Published: April 2012

AbstractNonisothermal melt crystallization kinetics of syndiotactic polypropylene (sPP)/alumina nanocomposites were investigated via differential scanning calorimetry. The addition of alumina nanoparticles significantly increases the number of nuclei and promotes the crystallization rate of sPP. Nonisothermal melt crystallization kinetics was analyzed by fitting the experimental data to a Nakamura model using Matlab. The average values of Avrami exponent n are 1.7 for both sPP and sPP/Al2O3 nanocomposites during slow cooling, which implies a two‐dimensional growth is the predominant mechanism of crystallization following a heterogeneous nucleation. The two nanocomposites give n values equal to 2.3 during faster cooling, indicating that the main growth type taking place for sPP/alumina nanocomposites is also the two‐dimensional growth. The subsequent melting behavior shows that the presence of alumina nanoparticles changed both the cold crystallization and the recrystallization of sPP. © 2012 Wiley Periodicals, Inc.

Chemically modifiable fluorinated copolymer nanoparticles for 19F‐MRI contrast enhancement
Authors: Bailey Mark M. , Kline Steven R. , Anderson Michael D. , Staymates Jessica L. , Berkland Cory 
Published: April 2012

AbstractRecently there has been interest in developing imaging contrast media for magnetic resonance imaging (MRI) that contain biologically rare, magnetically active nuclei such as fluorine. In principle, fluorinated contrast agents can be used to generate highly selective 19F magnetic resonance images that can be superimposed over complimentary 1H magnetic resonance images to provide an anatomical context for the fluorinated contrast agent. Additionally, nanoparticles can be made to target various pathological sites via active and passive targeting mechanisms. In this study, fluorinated nanoparticles were produced using a free radical polymerization of vinyl formamide monomers with two different fluorinated monomers. The nanoparticles showed a clear, single 19F‐NMR signal. Additionally, surface amide groups were hydrolyzed to primary amines to yield additional surface reactivity. Fluorinated nanoparticles produced using a free‐radial polymerization method yield a new nanoparticle for 19F‐MRI applications with potential for facile functionalization. © 2012 Wiley Periodicals, Inc.

Published: April 2012

AbstractMolecularly imprinted membranes with different ratio of acrylamide (AM) versus methacrylic acid (MAA) were prepared by photocopolymerization on commercial filter paper using nicosulfuron as the template. The structures, the thermal stability, and the morphology of membranes were characterized by infrared spectroscopy (IR), thermogravimetric analysis (TGA), and scanning electron microscopy (SEM), respectively. Static equilibrium binding and competitive recognition properties of the membranes to nicosulfuron and its analogs (pyrazosulfuron ethyl and bensulfuron methyl) were tested. The results showed that nicosulfuron‐imprinted membranes had the best recognition capacity to nicosulfuron compared with its analogs. The biggest selectivity factors of
${\rm \alpha }_{{\rm N}_{\rm 1} /{\rm P}_{\rm 2} }$
and
${\rm \alpha }_{{\rm N}_{\rm 1} /{\rm B}_{\rm 3} }$
were 1.28 and 1.83 and the imprinted factor reached to 2.34. The results of this study implied that the molecularly imprinted composite membranes could be used as separation membranes for nicosulfuron enrichment. The Scatchard plot revealed that one class of binding sites was mainly produced in the imprinted composite membrane in the studied concentration range of nicosulfuron. © 2012 Wiley Periodicals, Inc.

Poly(vinylidene fluoride‐co‐hexafluoropropylene) nanocomposites incorporating cellulose nanocrystals with potential applications in lithium ion batteries
Authors: Kelley Jeremiah , Simonsen John , Ding Jie 
Published: April 2012

AbstractCellulose nanocrystals (CNCs) have received considerable attention recently because CNCs can be produced from renewable materials such as straw, wood, cotton, and sea animals (tunicates). CNCs are one of the stiffest organic materials, with an estimated tensile modulus (E) of 80–160 GPa depending on the starting material. In addition, composites incorporating CNCs have been fabricated from a variety of polymer matrices and CNCs have been shown to increase the E significantly and to a lesser extent the tensile strength (TS). A copolymer of poly(vinylidene fluoride) (PVDF), PVDF‐co‐hexafluoropropylene) (PVDFHFP), has received interest over the years in the area of lithium ion battery separator technology. However, the mechanical properties of neat PVDFHFP do not meet the necessary requirements for commercial separators, especially the low E. In this work, novel PVDHFHFP/CNC nanocomposite films were fabricated and characterized. It was found that incorporation of CNCs improves the E and TS. The improvement in mechanical properties of PVDFHFP upon addition of CNCs makes PVDFHFP a more suitable candidate for polymer separators in lithium ion batteries. © 2012 Wiley Periodicals, Inc. J.

Evaluation of the phytomass source for composite preparation
Authors: Šimkovic Ivan , Šurina Igor , Mikulášik Radoslav , Orságová Anna , Ház Aleš , Schwarzinger Clemens 
Published: April 2012

AbstractThe properties of lignocellulose materials from the trunk and bark of trees, and from agricultural sources were investigated by thermogravimetry (TG) and pyrolysis–gas chromatography/mass spectrometry (Py‐GC/MS). The goal was to learn which of the phytomass sources is the most accessible to dehydration and aldol reactions, and in this way could be considered suitable for composite preparation by the thermal pressing treatment. The bagasse second differential thermal analysis peak in air is at the highest temperature acceptable for intermolecular dehydration/crosslinking, and therefore we consider bagasse to be the most suitable candidate for composite preparation. From the TG results in air at 250°C, it follows that willow wood and bagasse are the most thermally resistant sources. The data obtained by Py‐GC/MS analysis showed glycolaldehyde and acetic acid as dominant markers related to adhesion properties via aldol condensation. The detected sum amount of glyceraldehyde and acetic acid decreases in the order: beech wood > bagasse > acacia wood > sugar beet pulp, whereas the remaining species produced much less of it. By comparing results run at above conditions with composite preparation using the pressing thermal treatment at a temperature of 150°C and pressures up to 800 kPa, the suggested evaluation was examined for application on sugar beet residue. © 2012 Wiley Periodicals, Inc.
