BACKGROUND: Different kinds of chronic diseases might imply different dimensions of caregiver burden, not previously described among the caregivers to recipients from the general elder population. AIM: The main objective was to examine differences in burden between the 343 caregivers to persons with different diagnoses. METHODS: A group of elderly recipients of informal care (n = 343) from the general population study 'Good Aging in Skåne' (GÅS) Sweden, were divided into five diagnostic groups: dementia (n = 90), heart and lung diseases (n = 48), stroke (n = 62), fractures (n = 66), depression (n = 40) and the group "other", consisting of different diagnoses (n = 37) according to ICD-10...

In haploid Saccharomyces cerevisiae, a complex recombination system regulates mating-type switching and requires one MAT expression locus, two donor cassettes (HML and HMR) and the HO endonuclease that catalyses gene conversion. Zygosaccharomyces rouxii is the most distant species from S. cerevisiae with a functional HO, but with a poorly understood mating-type switching. Here, we described that two sub-cultures of the type strain CBS 732T underwent the α to a genotype switching leading to mixed MATα and MATa populations...

Clinical studies that focused on treating schizophrenia showed that Calculus Bovis Sativus (CBS), a substitute of Calculus Bovis, when used in combination with haloperidol could significantly lower the dosage of haloperidol compared with treatment with haloperidol alone, whereas efficacy was maintained. The aim of this study was to investigate the synergetic anti-schizophrenia effects in rats using CBS in combination with haloperidol. An open field test was conducted to verify the pharmacodynamic effects of a combination treatment of CBS and haloperidol on MK-801-induced schizophrenic rats...

Vibrationally state selective overtone spectroscopy and state- and nuclear spin-dependent predissociation dynamics of weakly bound ortho- and para-Ne-H2O complexes (D0(ortho) = 34.66 cm-1 and D0(para) = 31.67 cm-1) are reported, based on near-infrared excitation of van der Waals cluster bands correlating with vOH = 2 ← 0 overtone transitions (|02-〉 and |02+〉) out of the ortho (101) and para (000) internal rotor states of the H2O moiety. Quantum theoretical calculations for nuclear motion on a high level potential energy surface [CCSD(T)/VnZf12 (n = 3, 4)], corrected for basis set superposition error and extrapolated to the complete basis set (CBS) limit, are employed to successfully predict and assign Π-Σ, Σ-Σ, and Σ-Π infrared bands in the spectra, where Σ or Π represent approximate projections of the body-fixed H2O angular momentum along the Ne-H2O internuclear axis...

Hydrogen sulfide (H2S) is a gaseous transmitter with well-known biological actions in a wide variety of tissues and organs. The potential involvement of this gas in physiological and pathological processes in the eye has led to several in vitro, ex vivo, and in vivo studies to understand its pharmacological role in some mammalian species. Evidence from literature demonstrates that 4 enzymes responsible for the biosynthesis of this gas (cystathionine β-synthase, CBS; cystathionine γ-lyase, CSE; 3-mercaptopyruvate sulfurtransferase, 3MST; and d-amino acid oxidase) are present in the cornea, iris, ciliary body, lens, and retina...

The acidities of 18 5,6-substituted uracils have been numerically estimated as pKa values in terms of three theoretical models. The first scheme includes the calculation of the gas-phase acidity of uracil with the G3MP2B3 method and taking into account the solvent effect using the polarizable continuum approximation PCM(SMD)-TPSS/aug-cc-pVTZ. The second model is one-step and implies calculating of the free Gibbs energies of the hydrate complex of uracil (and its anion) with 5 water molecules by the TPSS/aug-cc-pVTZ method...

BACKGROUND: Hydrogen sulphide (H2S), a member of the gasotransmitters family, is known to play patho-physiological role in different body systems including during pregnancy. But its involvement in myometrial spontaneity and associated signalling pathways in uterus in non-pregnant animals is yet to be studied. Present study describes the effect of L-cysteine, an endogenous H2S donor, on isolated myometrial strips of non-pregnant buffaloes and the underlying signaling mechanism(s). RESULTS: L-cysteine (10 nM-30 mM) produced concentration-dependent contractile effect on buffalo myometrium which was extracellular Ca2+ and L-type calcium channels-dependent...

Hydrogen sulfide (H2S) and carbon monoxide (CO) exert gastroprotection against acute gastric lesions. We determined the cross-talk between H2S and CO in gastric ulcer healing process and regulation of gastric blood flow (GBF) at ulcer margin. Male Wistar rats with acetic acid-induced gastric ulcers were treated i.g. throughout 9 days with vehicle (control), NaHS (0.1-10 mg/kg) +/- zinc protoporphyrin (ZnPP, 10 mg/kg), D,L-propargylglycine (PAG, 30 mg/kg), CO-releasing CORM-2 (2.5 mg/kg) +/- PAG. GBF was assessed by laser flowmetry, ulcer area was determined by planimetry/histology...

Gut microbiota is of considerable importance for each host. Despite this, germ-free animals can be obtained and raised to sexual maturity and consequences of the presence or absence of gut microbiota on gene expression of the host remain uncharacterised. In this study, we performed an unbiased study of protein expression in the caecum of germ-free and colonised chickens. The major difference between these two groups was in the expression of immunoglobulins which were essentially absent in the germ-free chickens...

BACKGROUND: Differential diagnosis of atypical parkinsonian disorders, i.e. dementia with Lewy bodies (DLB), progressive supranuclear palsy (PSP) or corticobasal syndrome (CBS) still remains problematic. Furthermore, DLB may overlap with Alzheimer's disease (AD) in the early stages of disease. OBJECTIVE: To determine whether transcranial magnetic stimulation (TMS) can be used to classify atypical parkinsonian disorders and AD. METHODS: A paired-pulse TMS multi-paradigm approach assessing multiple intracortical circuits, as short interval intracortical inhibition-facilitation and short latency afferent inhibition, was used to model a decision tree analysis and determine diagnostic accuracy in classifying different neurodegenerative disorders...

A systematic investigation on the potential basicity of the novel hyperlithiated species Li3F2O and Li3F2(OH)n (n = 1, 2) based upon the superalkali cluster Li3F2 was conducted using high-level ab initio techniques. Equilibrium structures for both the neutral and anionic states in the gas-phase were identified and their relative stabilities using atomization enthalpies are analysed and compared with their respective proton affinities and gas-phase basicities. Our calculations, using a modified form of the CBS-QB3 composite method, identified several unique structures that possess superbase potential comparable to the proton affinity of Roger Alder's canonical Proton Sponge...

BACKGROUND: Patients with neglect ignore or respond slower to contralesional stimuli. Neglect negatively influences independence in activities of daily living (ADL). Prism adaptation (PA) is one of the most frequently studied treatments, yet there is little evidence regarding positive effects on neglect behavior in ADL. OBJECTIVE: To assess whether PA in the subacute phase ameliorates neglect in situations of varying complexity. METHODS: A total of 70 neglect patients admitted for inpatient stroke rehabilitation received either PA or sham adaptation (SA) for 2 weeks, with full access to standard treatment...

Cucurbitadienol has anti-inflammation, anti-cancer activities, and acts as a precursor of traditional Chinese medicine active ingredients mogroside and cucurbitacine. For construction of a Sacchromyces cerevisiae cell factory for production of cucurbitadienol, we firstly cloned a cucurbitadienol synthase (CBS) gene from Siraitia grosvenorii. Then, through heterologous expression of CBS in the triterpenoid chassis strain WD-2091, the engineered strain could produced 27.44 mg•L ⁻¹ cucurbitadienol, which was determined by GC-MS...
