Eight compounds were isolated from the water-soluble fraction of Wikstroemia indica (L.) C.A. Mey., including two new neolignans (isonitidanin-4-O-β-D-glucoside (3) and threo-citrusin B (6)), four known neolignans (1, 2, 4, and 5), along with two previously reported lignans (7 and 8). Spectral analysis (1D, 2D NMR, and HR-ESI-MS/MS) was used to identify their chemical structures. Except for compou
Apidaecin 1b (Api), the first characterized Type II Proline-rich antimicrobial peptide (PrAMP), is encoded in the honey bee genome. It inhibits bacterial growth by binding in the nascent peptide exit tunnel of the ribosome after the release of the completed protein and trapping the release factors. By genome mining, we have identified 71 PrAMPs encoded in insect genomes as pre-pro-polyproteins. Ha
This study examined how sycophantic versus non-sycophantic AI behavior influences user trust and whether narcissism and need for cognitive closure shape these effects. In a 2 × 2 between-subjects online experiment, 318 adult AI users viewed a short video of a chat interaction between a user and an AI assistant that either validated the user’s position (sycophantic) or offered corrective or balance
In response to increasing frequencies of penicillin-non-susceptible pneumococci (PNSP), for which the MIC of penicillin was greater than or equal to0.12 mg/L, in Sk (a) over circle ne County, southern Sweden, national recommendations were initiated in 1995 to limit the spread of pneumococci with high MICs (greater than or equal to0.5 mg/L) of penicillin (PRP), especially among children of preschoo
Information till patienter och besökare Är dina händer rena? Rena händer minskar risken för infektioner Alla har bakterier på händerna. När du är sjuk eller genomgår en behandling, är du känslig för infektioner. Ett bra sätt att minska risken för att få en infektion är att hålla händerna rena. Gör handhygien till en rutin under vårdtiden. Handhygien Under vårdtiden ska du rengöra händerna med hand

A β-mannosidase was purified to homogeneity from the culture filtrate of Aspergillus niger. A specific activity of 500 nkat mg−1 and a 53-fold purification was achieved using ammonium sulfate precipitation, anion-exchange chromatography, and gel filtration. The isolated enzyme has an isoelectric point of 5.0 and appears to be a dimer composed of two 135-kDa subunits. It is a glycoprotein and conta
The major intrinsic proteins (MIPs) form a large protein family of ancient origin and are found in bacteria, fungi, animals, and plants. MIPs act as channels in membranes to facilitate passive transport across the membrane. Some MIPs allow small polar molecules like glycerol or urea to pass through the membrane. However, the majority of MIPs are thought to be aquaporins (AQPs), i.e., they are spec
We present an interactive, searchable expressed sequence tag database for the periwinkle snail Littorina saxatilis, an upcoming model species in evolutionary biology. The database is the result of a hybrid assembly between Sanger and 454 sequences, 1290 and 147 491 sequences respectively. Normalized and non-normalized cDNA was obtained from different ecotypes of L. saxatilis collected in the UK an
Nontypeable Haemophilus influenzae (NTHi) is one of the main aetiologies of childhood bacterial infections as well as exacerbations in COPD patients. Currently, no licensed NTHi vaccine exists. In the present study, we evaluated the potential of the conserved and ubiquitous surface protein Haemophilus Protein F (PF) as a vaccine candidate. Our results show that incubation of NTHi with anti-PF anti
To compare xylans from forestry with agricultural origins, hardwood xylan (birch) and cereal arabinoxylan (rye) were hydrolyzed using two variants of the xylanase RmXyn10A, full-length enzyme and catalytic module only, from Rhodothermus marinus . Cultivations of four selected bacterial species, using the xylooligosaccharide (XOS) containing hydrolysates as carbon source, showed selective growth of
Background Subjects in treatment for affective disorders are usually less satisfied with life compared to subjects with schizophrenia. Aims The aims of this study were to compare subjective quality of life (QoL) at adult age of adolescent onset psychotic disorders and analyse associated factors. Method Fifty-three patients with adolescent onset psychotic disorders were followed up at age 25, diagn
We have investigated the formation of supported bilayers by coadsorption of dipalmitoyl phosphatidylcholine (DPPC) with the nonionic surfactant P-D-dodecyl maltoside. The adsorption of mixed phospholipid-surfactant micelles on hydrophilic silica surfaces at 25 degrees C was followed as a function of bulk concentration by neutron reflection. Using chain-deuterated d(25)-beta-D-dodecyl maltoside and
308 consecutive patients with severe or complicated respiratory tract infections underwent fiber-optic bronchoscopy in the search for a microbiological etiology. Protected brush specimens were used for bacterial cultures and bronchoalveolar lavage (BAL) for virus isolation and cytological examination. Herpes simplex virus (HSV) was the most commonly found pathogen and was isolated in 37 patients.
Background. The accuracy of ultrasound in the diagnosis of congenital malformations has been the subject of many studies. Most of these are hospital-based studies over a limited period of years presenting high detection rates and also relatively high incidence of major malformations. We present here a large population-based study over a long period of years. Methods. The prenatal diagnoses are com
INTRODUCTION: Study aim was to find out if patients with Lenke type 1 curve exhibit smaller pedicles and specific pedicle width pattern compared with individuals with no scoliosis. MATERIALS AND METHODS: 4,828 pedicle width measurements (T1-L5) in 61 consecutive patients with adolescent idiopathic scoliosis of Lenke type 1 curve, 61 control subjects, and 20 patients with Lenke type 5 curve, were
