Background: Biorefineries usually focus on the production of low-value commodities, such as bioethanol, platform chemicals or single cell protein. Shifting production to bioactive compounds, such as antimicrobial peptides, could provide an opportunity to increase the economic viability of biorefineries.
Results: Recombinant production of the antimicrobial peptide pediocin PA-1 in Corynebacterium glutamicum was transferred from yeast extract-based media to minimal media based on lignocellulosic spent sulfite liquor.
Although programmed cell death ligand 1 (PD-L1) is best known for its role in immune suppression, tumor-intrinsic functions are emerging. Here, we report that tumor cells that express PD-L1 are sensitive to ferroptosis inducers such as imidazole ketone erastin (IKE). PD-L1 promotes ferroptosis sensitivity because it suppresses SLC7A11 expression and diminishes glutathione levels.

This study was motivated by our finding that the Hippo effectors YAP and TAZ can sustain the expression of laminin 332 (LM332), the predominant ECM ligand for the integrin β4, in breast carcinoma cells with epithelial differentiation. More specifically, we observed that YAP and TAZ regulate the transcription of the LAMC2 subunit of LM332.

Due to TTTS grade 3, fetoscopic laser ablation was performed at gestational week 16+1. Sonographic follow-up showed a cortical malformation of the right parietal lobe in the former donor, which was identified as PMG by MRI scans.

Several possible causes for this phenomenon have been investigated, including biophysiological adaptation, epigenetic or genetic mechanisms or lifestyle changes. This is the first study to show the effect modification of altitude and parity on the birth weight length ratio (BWLR) in women resident in moderate altitudes compared to a low sea level.
View Article and Find Full Text PDFFetal dysrhythmias are common abnormalities, which can be categorized into three types: rhythm irregularities, tachyarrhythmias, and bradyarrhythmias. Fetal arrhythmias, especially in high-risk pregnancies, require special monitoring and treatment. The aim of this study was to assess the stillbirth and early and late neonatal mortality rates for pregnancies complicated by fetal dysrhythmias from one single tertiary referral center from 2000 to 2022.

Comparison of CSCs and non-CSCs from multiple breast cancer models revealed that CSCs are distinguished by expression of α2,3 sialylated core2 O-linked glycans. We identified a lectin, SLBR-N, which binds to O-linked α2,3 sialic acids, that was able to enrich for CSCs in vitro and in vivo.

We reported that prominin2 is induced by ferroptotic stimuli and functions to resist ferroptotic death. Although this finding has significant implications for therapy, specific prominin2 inhibitors are not available.

Objective: To elucidate the interaction effect of education and global mental status on cognitive performance of older patients with progressive cognitive decline.
Methods: This retrospective study included 1,392 patients.
To minimize recurrence following resection of a cerebral metastasis, whole-brain irradiation therapy (WBRT) has been established as the adjuvant standard of care. With prolonged overall survival in cancer patients, deleterious effects of WBRT gain relevance. Sector irradiation (SR) aims to spare uninvolved brain tissue by applying the irradiation to the resection cavity and the tumor bed.

Objective: Cognitive impairment in multiple system atrophy (MSA) is common, but remain poorly characterized. We evaluated cognitive and behavioral features in MSA patients and assessed between-group differences for MSA subtypes and the effect of orthostatic hypotension (OH) on cognition.
Methods: This retrospective study included 54 patients with clinical diagnosis of possible and probable MSA referred to the Department of Neurology at Medical University of Innsbruck between 2000 and 2018.
Background And Purpose: CACNA1A encodes the α1 subunit of the neuronal calcium channel P/Q. CACNA1A mutations underlie three allelic disorders: familial hemiplegic migraine type 1 (FHM1), episodic ataxia type 2 (EA2) and spinocerebellar ataxia type 6 (SCA6). A clear-cut genotype-phenotype correlation is often lacking since clinical manifestations may overlap.

However, only a few examples have been obtained to date - all requiring lengthy, multi-step processes. Herein, we present the first preparation of 5,7,12,14-tetracyanopentacene (TCP) and a facile, scaled-up preparation of 6,13-dicyanopentacene (DCP).

Methods: As part of the first randomized, sham-controlled multicenter trial on DBS in medication-refractory primary cervical dystonia (ClinicalTrials.gov, number NCT00148889), a subgroup of 13 patients aged 39 to 69 underwent prospective neuropsychological long-term follow-up assessments.
Episodic ataxia type 2 (EA2) is an autosomal dominant inherited neurological disorder that is characterized by paroxysmal episodes of ataxia. The causative gene for EA2 is CACNA1A which codes for the alpha 1A subunit of the voltage-gated P/Q-type calcium channel (Cav2.1).
View Article and Find Full Text PDFPatients with mild cognitive impairment (MCI) are by definition still autonomous in daily life and therefore make their own decisions, for example, concerning their own or their partners' health care. Health care information typically contains complex mathematical constructs like proportions, probabilities, and survival rates. The purpose of this study was to investigate whether patients with MCI have difficulties with understanding health numeracy questions and to explore the impact of declining cognitive functions.

Methods: RL was investigated in a clinical study including subjects classified as early AD (n=37), MCI (n=34), and aged normal controls (n=46).
Executive dysfunction (ED) is a frequent consequence of neurological disorders, such as stroke, trauma or dementia, but also appears in normal aging. We developed a German version of the Frontal Assessment Battery (FAB-D), a short test which has previously been developed (Dubois et al., Neurology 55:1621-1626, 2000) to detect ED during bedside screening.

Background: FHM is a rare autosomal-dominant subtype of migraine with aura, characterized by some degree of hemiparesis during the aura. In a previous study, we showed preserved and impaired cognitive functions in patients with FHM.
