Introduction Community-acquired pneumonia (CAP) affects approximately 1.5 million patients annually in the United States, leading to significant acute and long-term clinical outcomes. CAP is increasingly recognized as a multisystemic disease with potential sequelae affecting various organ systems, including the neurologic, pulmonary, cardiovascular, musculoskeletal, metabolic, and renal systems. The primary objective of this study is to review literature on long-term cognitive impairment, dementia, and decreased survival following CAP hospitalization. Additionally, the potential role of the gut-lung-brain axis in the pathogenesis of these outcomes is explored. Methods A comprehensive review of existing literature was conducted, focusing on studies that examined cognitive impairment, dementia, and mortality in patients hospitalized for CAP. Relevant studies were identified through a systematic search of medical databases, and data were extracted on study design, population characteristics, cognitive assessments, and outcomes. The review also incorporated mechanistic insights into the gut-lung-brain axis to hypothesize its role in the long-term sequelae of CAP. Results The review identified multiple studies demonstrating an increased risk of cognitive impairment and dementia following CAP hospitalization. Patients hospitalized for CAP had a 1.5 to 2.5 times higher risk of developing cognitive deficits compared to controls. This cognitive decline was not limited to elderly patients but spanned all adult age groups. Furthermore, CAP was associated with a significant reduction in life expectancy. Patients discharged after CAP hospitalization reached 50% mortality within three years, compared to seven years for those hospitalized for other reasons. The most pronounced decrease in survival was observed in CAP patients requiring ICU admission and immunocompromised patients. Conclusion CAP is associated with significant long-term cognitive impairment and decreased survival. The proposed gut-lung-brain axis mechanism suggests that CAP-related dysbiosis leads to chronic systemic inflammation and neuroinflammation, potentially contributing to cognitive decline and increased mortality. Understanding the role of this axis may offer new therapeutic strategies for managing the long-term neurological consequences of CAP. Future research should focus on high-risk populations to develop targeted interventions aimed at mitigating these severe outcomes.

Unsaturated hydraulic conductivity function (Kh) is an important soil parameter stating water transmission characteristics within the soil mass. It is essentially required in designing of drip irrigation systems. There are many laboratory and in-situ measurement techniques available for the measurement of Kh. These methods have associated limitations. Soil particle distribution curve had been also used for Kh estimation which is laborious and associated with own limitations. A point source field dripper model (PSFDM) using Wooding [1] theory was first time used by Shani et al. [2] for Kh measurement in the field. Experimental set up used earlier had great limitations of controlling dripper discharge by maintaining appropriate pressure in drip line. Hence an experimental set up (micro-irrigation simulator) was developed for in-situ measurement of Kh which simulates real field drip conditions. Experiments was conducted to measure steady state saturated fronts against 2.02, 4.04, 7.56 and 8.31 lph dripper discharges maintaining one atmospheric pressure in drip line in recently harvested wheat field. Inverse saturated radii (r-1) were plotted against water flux density q (cm hr-1). Slope and intercept of the plotted line was worked out and Ks and α were calculated using steady state PSFD theory. Ks value was calculated as 50.03 cm/day and α as 0.1048 cm-1 using PSFD model of Shani et al. [2] and 60.00 cm/day and 0.0984 cm-1 using PSFD model of Warrick [3]. Ks value measured by using inverse auger hole method was 8.694 cm/day and by infiltrometer test 19.13 cm/day. The PSFDM is relatively new method and is useful for measuring Kh of tilled zone. Kh values are much higher than the values of Kh of untilled soil at deeper depths due to compaction. The developed experimental set up has great compatibility with PSFD theory.
Phonoemissive spin tunneling in molecular nanomagnets
Authors: Garg A. 
Published: February 2012

AbstractA new mechanism is proposed for the magnetization reversal of molecular nanomagnets such as Fe8. In this process the spin tunnels from the lowest state near one easy direction to the first excited state near the opposite easy direction, and subsequently decays to the second easy direction with the emission of a phonon, or it first emits a phonon and then tunnels to the final state. This mechanism is the simplest imaginable one that allows magnetization relaxation in the presence of a longitudinal magnetic field that is so large that the nuclear spin environment cannot absorb the energy required for energy conservation to hold. It is proposed as a way of understanding both magnetization realaxation and Landau‐Zener‐Stückelberg (LZS) experiments. The requisite Fermi golden rule rate, and the spin‐flip rates are calculated. The rates are too low to affect the minima in the LZS tunneling as a function of transverse field, and also somewhat low for relaxation. Thus a full understanding of magnetic relaxation in the experiments remains an open question.
A quantum spin‐liquid in correlated relativistic electrons

Published: February 2012

AbstractIn recent years, an increasing number of systems displaying exotic quantum states like unconventional superconductivity, quantum spin‐liquids, or topological states were experimentally found. Here we summarize findings in quantum Monte Carlo simulations of correlated electrons on a honeycomb lattice, the structure of graphene, that revealed an unexpected spin‐liquid emerging between a state described by massless Dirac fermions and an antiferromagnetically ordered Mott insulator. Moreover, we found that this quantum‐disordered state is a resonating valence‐bond (RVB) liquid, akin to the one proposed for high temperature superconductors. This was the first unbiased determination of a RVB‐liquid in an electronic system.
Composites from northern red oak (Quercus robur) leaves and plant oil‐based resins

Published: February 2012

AbstractComposite materials were successfully made out of plant oil‐based resin and northern red oak (Quercus robur) leaves collected in the fall. The viscosities of the bio‐based resins (MAESO and MAELO) were suited to high temperature resin transfer molding (RTM) and vacuum‐assisted resin transfer molding (VARTM) processing. The leaves have a waxy epidermal surface layer that needs to be dewaxed prior to use in a composite part. We used different treatments (such as benzene–ethanol, boiling water, and strong detergent) to dewax the leaves; all three methods seem to give good results; but boiling water and strong detergent were considered the best treatments for the dewaxing of leaves and boiling water was considered the greenest dewaxing method. The compatibility between the resin and the leaves was improved with a silane treatment which resulted in composites with higher mechanical stiffness than the resin itself. With 10 wt % leaves, we obtained an improvement in the composite modulus of about 14% from which we could estimate the leaf modulus at about 5.3 GPa. An alternative method to produce biocomposites from leaves without the need for silane treatments consists in carbonizing the leaves first at 215°C for 12 h, and then at 450°C for 1 h. The composites made with leaves and bioresins derived from functionalized triglycerides have the potential for use in high volume applications with low costs such as housing, construction, civil infrastructure, toys, and furniture. The use of leaves as a biocomposite filler has several advantages including (a) reduced cost, (b) improved properties of the resin, (c) composites with high bio content, (d) removal of a waste material with subsequent prevention of burning with attendant health hazards, and (e) interesting design aesthetics for interior and exterior decoration. © 2012 Wiley Periodicals, Inc.

AbstractRuthenium(III)‐substituted α‐Keggin‐type silicotungstates with pyridine‐based ligands, [SiW11O39RuIII(Py)]5−, (Py: pyridine (1), 4‐pyridine‐carboxylic acid (2), 4,4′‐bipyridine (3), 4‐pyridine‐acetamide (4), and 4‐pyridine‐methanol (5)) were prepared by reacting [SiW11O39RuIII(H2O)]5− with the pyridine derivatives in water at 80 °C and then isolated as their hydrated cesium salts. These compounds were characterized using cyclic voltammetry (CV), UV/Vis, IR, and 1H NMR spectroscopy, elemental analysis, titration, and X‐ray absorption near‐edge structure (XANES) analysis (Ru K‐edge and L3‐edge). Single‐crystal X‐ray analysis of compounds 2, 3, and 4 revealed that RuIII was incorporated in the α‐Keggin framework and was coordinated by pyridine derivatives through a RuN bond. In the solid state, compounds 2 and 3 formed a dimer through ππ interaction of the pyridine moieties, whereas they existed as monomers in solution. CV indicated that the incorporated RuIII–Py was reversibly oxidized into the RuIV–Py derivative and reduced into the RuII–Py derivative.

AbstractWe have previously reported that the trimeric Zn2+–cyclen complex (tris(Zn2+–cyclen), [Zn3L1]6+) and the trianion of trithiocyanuric acid (TCA3−) assembled in a 4:4 ratio to form a cuboctahedral supramolecular cage, [(Zn3L1)4(TCA3−)4]12+ (hereafter referred to as a Zn–cage), in neutral aqueous solution (cyclen=1,4,7,10‐tetraazacyclododecane). Herein, we examined the molecular recognition of C1–C12 hydrocarbons (CnH(2n+2) (n≈1–12)), cyclopentane, cyclododecane, cis‐decalin, and trans‐decalin by the Zn–cage under normal atmospheric pressure. This cage complex was also able to encapsulate guest molecules that had larger volumes than that of the inner cavity of the Zn–cage, thereby suggesting that the inner shape of the Zn–cage was flexible. Computational simulations of Zn–cage–guest complexes provided support for this conclusion. Moreover, the solvent‐accessible surface areas (SASA) of the Zn–cage host, guest molecules, and the Zn–cage‐guest complexes were calculated and the data were used to explain the order of stability determined by the guest‐replacement experiments. The storage of volatile molecules in aqueous solution by the Zn–cage is also discussed.
InCl3‐Driven Regioselective Synthesis of Functionalized/Annulated Quinolines: Scope and Limitations
Authors: Chanda Tanmoy , Verma Rajiv Kumar , Singh Maya Shankar 
Published: February 2012

AbstractThe efficient, regioselective synthesis of functionalized/annulated quinolines was achieved by the coupling of 2‐aminoaryl ketones with alkynes/active methylenes/α‐oxoketene dithioacetals promoted by InCl3in refluxing acetonitrile as well as under solvent‐free conditions in excellent yields. This transformation presumably proceeded through the hydroamination–hydroarylation of alkynes, and the Friedländer annulation of active methylene compounds and α‐oxoketene dithioacetals with 2‐aminoarylketones. In addition, simple reductive and oxidative cyclization of 2‐nitrobenzaldehyde and 2‐aminobenzylalcohol, respectively, afforded substituted quinolines. Systematic optimization of the reaction parameters allowed us to identify two‐component coupling (2CC) conditions that were tolerant of a wide range of functional groups, thereby providing densely functionalized/annulated quinolines. This approach tolerates the synthesis of various bioactive quinoline frameworks from the same 2‐aminoarylketones under mild conditions, thus making this strategy highly useful in diversity‐oriented synthesis (DOS). The scope and limitations of the alkyne‐, activated methylene‐, and α‐oxoketene dithioacetal components on the reaction were also investigated.

BACKGROUND: N‐methyl‐2‐pyrrolidone (NMP) is a solvent used in the petrochemical, and electronic industries, in pesticides production, veterinary drugs, and paint removers. The aim of study was to evaluate the relationship between the dose of NMP given orally and its effect on fertility in female rats and early development of their progeny. METHODS: Females were exposed by gavage 5 days/week to NMP at 150, 450, or 1000 mg/kg/day 2 weeks before mating, during mating, gestation, and lactation. On the first postnatal day (PND 1), the live and dead pups were counted, weighed, and gender was determined. On PND 4, the litters were culled to eight animals each and balanced for gender. Young animals were observed during 3 weeks after birth. RESULTS AND CONCLUSION: Fertility index did not significantly differ in the control and the group exposed at 150 mg/kg/day but it was significantly lower in the groups exposed at 450 or 1000 mg/kg/day. The number of live pups in the group exposed to the highest dose was significantly lower and the number of stillbirths in litters was significantly greater. Survival of the pups from all exposed groups during the 3 weeks after birth was significantly lower than the control animals. The results of our study indicate that intragastric exposure of female rats to NMP before pregnancy during gestation causes significant impairment in female fertility and intrauterine mortality rates. At lower doses, toxic or slightly toxic to the mothers, this substance causes decrease in viability and physical development of progeny.

Published: February 2012

ABSTRACTBackgroundDespite the increased interest in female offending trajectories over the last decades, knowledge is still limited.AimTo meet the need for more knowledge on female offending trajectories by studying sex differences in criminal career patterns.MethodData on 518 female and 2567 male offenders up to age 30 from the Swedish longitudinal Project Metropolitan study were analysed using latent class analysis.ResultsThe female offenders were much less predisposed to offend than the males, but when they did, they tended to follow a similar set of trajectories to males in their criminal development over time. Four criminal career patterns were identified for each sex. Two patterns were the same between the sexes, and two were gender unique. All career patterns had meaningful and distinct associations with crime characteristics.ConclusionsOur study presents indicators relating both to gender differences and to heterogeneity within the group of female offenders. One important finding was the identification of an adult‐onset offender group unique to females. This group was characterised by high criminal activity over the years following their late onset. Further research will focus on the childhood origins, pathways and outcomes of different female antisocial and criminal careers. Copyright © 2012 John Wiley & Sons, Ltd.
