Managing older medical patients in hospital: a study of the outcomes from a shift of resources to the 'front door'.

We performed a retrospective cohort comparison study to look at the processes for concentrating geriatric resources in the acute admissions area in a general hospital in the UK and compare key outcomes. The number of consultant geriatricians and other staff working at the 'front door' - acute medical unit (AMU) and short stay ward (SSW) - was increased. We compared 'front door' outcomes with whole department outcomes in 2013 and 2014, looking at the proportion of patients discharged within 3 and 5 days of admission, the proportion discharged from the 'front door', mean lengths of stay (LOS) and readmissions within 28 days of discharge.

MicroRNA-Mediated Downregulation of the Potassium Channel Kv4.2 Contributes to Seizure Onset.

Seizures are bursts of excessive synchronized neuronal activity, suggesting that mechanisms controlling brain excitability are compromised. The voltage-gated potassium channel Kv4.2, a major mediator of hyperpolarizing A-type currents in the brain, is a crucial regulator of neuronal excitability.

Acculturation and enculturation as predictors of psychological help-seeking attitudes (HSAs) among racial and ethnic minorities: A meta-analytic investigation.

Psychological services are culturally encapsulated for dominant cultural groups, and racial minorities underutilize treatment even though they suffer from more severe psychological distress. Sociocultural factors such as acculturation (one's adaptation into mainstream group) and enculturation (one's adherence to culture of heritage) are hypothesized to affect minorities' attitudes toward seeking psychological services. This meta-analysis examined 3 methods to assess acculturation/enculturation-unidimensional acculturation, bidimensional acculturation, and bidimensional enculturation as predictors of help-seeking attitudes (HSAs)-both positive and negative attitudes-among racial and ethnic minorities in 207 samples drawn from 111 research reports.

Over 75% incident-photon-to-current efficiency without solid electrodes.

The efficiency of photoelectrochemical reactions is conventionally defined in terms of the ratio between the current responses arising from the collection of carriers at electrical contacts and the incident photon flux at a given wavelength, i.e. the incident-photon-to-current-efficiency (IPCE).

Comment on 'Carbon and fullerene nanomaterials in plant system'.

A recent review article entitled "Carbon and fullerene nanomaterials in plant system" published in this journal, misinterprets a component of our (published) work on the interactions of carbon nanotubes with plants. In this comment, we provide the rationale to counter this misconstruction.

Pattern of Pediatric Admissions in a Tertiary Care Hospital of Central Nepal.

Introduction: An understanding of the epidemiological trend in hospital admissions, including morbidity and mortality patterns and the economic impact, is critical for healthcare planning and appropriate resource allocation. As we find very few literature on the pattern of paediatric admissions outside Kathmandu Valley, it is essential to conduct studies in the various parts of the country to determine the paediatric inpatient burden as well resource allocations.

Methods: A retrospective study was carried out at Department of Pediatrics, College of Medical Sciences-Teaching Hospital, Bharatpur, Chitwan, Nepal over a period of one year.

Magnetically recoverable Cu(0)/Fe3O4 catalyzed highly regioselective synthesis of 2,3,4-trisubstituted pyrroles from unactivated terminal alkynes and isocyanides.

An efficient, one pot tandem nano Cu(0)/Fe3O4 catalyzed highly regioselective synthesis of 3-substituted pyrrole-2,4 dicarboxylates from unactivated terminal alkynes and isocyanides has been developed. This strategy exhibits an unprecedented double addition of isocyanides on unactivated terminal alkynes to obtain trisubstituted pyrroles in high yields. Furthermore, the catalyst was magnetically recovered and reused five times without any appreciable loss of activity.

Silane grafted chitosan for the efficient remediation of aquatic environment contaminated with arsenic(V).

Hypothesis: Chitosan, naturally abundant biomaterial showed an insignificant affinity toward arsenate. The incorporation of organosilane could improve the physical and chemical properties of chitosan for the efficient removal of arsenate from aquatic environment.

Experiment: The hybrid materials were obtained by grafting the natural biopolymer chitosan with 3-mercaptopropyl trimethoxysilane (CHMS) and trimethoxy-octylsilane (CHTS).

Quantitative Trait Locus Analysis of Seed Germination and Seedling Vigor in Brassica rapa Reveals QTL Hotspots and Epistatic Interactions.

The genetic basis of seed germination and seedling vigor is largely unknown in Brassica species. We performed a study to evaluate the genetic basis of these important traits in a B. rapa doubled haploid population from a cross of a yellow-seeded oil-type yellow sarson and a black-seeded vegetable-type pak choi.

Case Series of Pancreatitis with Uncommon Presentations.

Acute pancreatitis is an inflammatory disease characterized by local tissue injury which can trigger a systemic inflammatory response. Vascular complications of pancreatitis are a major cause of morbidity and mortality. Pulmonary embolism in acute pancreatitis has been reported to be very rare.

Visible-Light/Photoredox-Mediated sp(3) C-H Functionalization and Coupling of Secondary Amines with Vinyl Azides in Flow Microreactors.

Structurally diverse imidazole derivatives were synthesized by a visible-light/[Ru(bpy)3 ][(PF6 )2 ]-mediated coupling of vinyl azides and secondary amines in flow microreactors. This operationally simple and atom-economical protocol allows the formation of three new C-N bonds through the functionalization of sp(3)  C-H bonds adjacent to the secondary nitrogen atom. In order to get mechanistic insight of the coupling reaction, several control experiments were carried out and discussed.

Targeting Mycobacterium tuberculosis Biotin Protein Ligase (MtBPL) with Nucleoside-Based Bisubstrate Adenylation Inhibitors.

Mycobacterium tuberculosis (Mtb), responsible for both latent and symptomatic tuberculosis (TB), remains the second leading cause of mortality among infectious diseases worldwide. Mycobacterial biotin protein ligase (MtBPL) is an essential enzyme in Mtb and regulates lipid metabolism through the post-translational biotinylation of acyl coenzyme A carboxylases. We report the synthesis and evaluation of a systematic series of potent nucleoside-based inhibitors of MtBPL that contain modifications to the ribofuranosyl ring of the nucleoside.

Fast and efficient detection of tuberculosis antigens using liposome encapsulated secretory proteins of Mycobacterium tuberculosis.

Purpose: A rapid and efficient diagnostic test was developed for the detection of Mycobacterium tuberculosis antigens in serum samples of active tuberculosis (TB) and extrapulmonary TB patients via a liposomal agglutination-based method.

Methods: A rapid card test has been developed to facilitate the recognition of high-affinity binding rabbit raised purified culture filtrate protein antibodies coupled on the surface of activated liposomal preparation. In the presence of TB antigens, the polyclonal antibodies bound to the liposomal particles demonstrate a visible agglutination reaction.

Efficient Purification of rhG-CSF and its PEGylated Forms and Evaluation for In Vitro Activities.

Granulocyte-colony stimulating factor (G-CSF) has commonly been used to help the patients to recover from neutropenia inflicted due to radiotherapy, organ transplants and chemotherapy. As the number of people undergoing these therapies and procedures are increasing world-wide, the need for more economical ways of G-CSF production and improvement in its efficacy has become increasingly crucial. In the present study, recombinant human G-CSF (rhG-CSF) was expressed in E.

A guide to use photocontrollable fluorescent proteins and synthetic smart fluorophores for nanoscopy.

Recent advances in nanoscopy, which breaks the diffraction barrier and can visualize structures smaller than the diffraction limit in cells, have encouraged biologists to investigate cellular processes at molecular resolution. Since nanoscopy depends not only on special optics but also on 'smart' photophysical properties of photocontrollable fluorescent probes, including photoactivatability, photoswitchability and repeated blinking, it is important for biologists to understand the advantages and disadvantages of fluorescent probes and to choose appropriate ones for their specific requirements. Here, we summarize the characteristics of currently available fluorescent probes based on both proteins and synthetic compounds applicable to nanoscopy and provide a guideline for selecting optimal probes for specific applications.

Physico-chemical studies in the removal of Sr(II) from aqueous solutions using activated sericite.

Sericite, a mica based natural clay, was annealed at 800 °C for 4 h followed by acid activation using 3.0 mol/L of HCl at 100 °C in order to obtain activated sericite (AS). The activation of sericite causes a significant increase in specific surface area.

A fast- and positively photoswitchable fluorescent protein for ultralow-laser-power RESOLFT nanoscopy.

Fluorescence nanoscopy has revolutionized our ability to visualize biological structures not resolvable by conventional microscopy. However, photodamage induced by intense light exposure has limited its use in live specimens. Here we describe Kohinoor, a fast-switching, positively photoswitchable fluorescent protein, and show that it has high photostability over many switching repeats.
