Impact of the Voltage-Gated Calcium Channel Antagonist Nimodipine on the Development of Oligodendrocyte Precursor Cells.

Multiple sclerosis (MS) is an inflammatory demyelinating disease of the central nervous system (CNS). While most of the current treatment strategies focus on immune cell regulation, except for the drug siponimod, there is no therapeutic intervention that primarily aims at neuroprotection and remyelination. Recently, nimodipine showed a beneficial and remyelinating effect in experimental autoimmune encephalomyelitis (EAE), a mouse model of MS.

Anti-CD19 CAR T cell therapy for refractory systemic lupus erythematosus.

Systemic lupus erythematosus (SLE) is a life-threatening autoimmune disease characterized by adaptive immune system activation, formation of double-stranded DNA autoantibodies and organ inflammation. Five patients with SLE (four women and one man) with a median (range) age of 22 (6) years, median (range) disease duration of 4 (8) years and active disease (median (range) SLE disease activity index Systemic Lupus Erythematosus Disease Activity Index: 16 (8)) refractory to several immunosuppressive drug treatments were enrolled in a compassionate-use chimeric antigen receptor (CAR) T cell program. Autologous T cells from patients with SLE were transduced with a lentiviral anti-CD19 CAR vector, expanded and reinfused at a dose of 1 × 10 CAR T cells per kg body weight into the patients after lymphodepletion with fludarabine and cyclophosphamide.

Low-Dose Subcutaneous or Intravenous Monoclonal Antibody to Prevent Malaria.

Background: New approaches for the prevention and elimination of malaria, a leading cause of illness and death among infants and young children globally, are needed.

Methods: We conducted a phase 1 clinical trial to assess the safety and pharmacokinetics of L9LS, a next-generation antimalarial monoclonal antibody, and its protective efficacy against controlled human malaria infection in healthy adults who had never had malaria or received a vaccine for malaria. The participants received L9LS either intravenously or subcutaneously at a dose of 1 mg, 5 mg, or 20 mg per kilogram of body weight.

Midkine Promotes Metastasis and Therapeutic Resistance via mTOR/RPS6 in Uveal Melanoma.

Unlabelled: Uveal melanoma is a rare form of melanoma that originates in the eye, exerts widespread therapeutic resistance, and displays an inherent propensity for hepatic metastases. Because metastatic disease is characterized by poor survival, there is an unmet clinical need to identify new therapeutic targets in uveal melanoma. Here, we show that the pleiotropic cytokine midkine is expressed in uveal melanoma.

Improvement of Atopic Dermatitis by Synbiotic Baths.

Atopic dermatitis (AD) is a widespread chronic inflammatory dermatologic disorder. This randomized, double-blind study aims to evaluate the effect of synbiotic baths with a defined mixture of six viable lactic acid bacteria (LAB) and prebiotics, without bacteria and prebiotics and placebo baths without prebiotics and bacteria to treat AD patients over a period of 14 days. Therefore, AD patients were randomly assigned into three groups using synbiotic ( = 7), prebiotics ( = 8) or placebo baths ( = 7).

Gastric bypass surgery in a rat model alters the community structure and functional composition of the intestinal microbiota independently of weight loss.

Background: Roux-en-Y gastric bypass (RYGB) surgery is a last-resort treatment to induce substantial and sustained weight loss in cases of severe obesity. This anatomical rearrangement affects the intestinal microbiota, but so far, little information is available on how it interferes with microbial functionality and microbial-host interactions independently of weight loss.

Methods: A rat model was employed where the RYGB-surgery cohort is compared to sham-operated controls which were kept at a matched body weight by food restriction.

Pseudomonas spp. are key players in agricultural biogas substrate degradation.

Anaerobic degradation (AD) of heterogeneous agricultural substrates is a complex process involving a diverse microbial community. While microbial community composition of a variety of biogas plants (BPs) is well described, little is known about metabolic processes and microbial interaction patterns. Here, we analyzed 16 large-scale BPs using metaproteomics.

Comparing microbial community compositions of biogas and sewage treatment plants by analyzing 16S rRNA gene data.

This article contains data of bacterial and archaeal community compositions and process parameters of 16 biogas (BPs) and ten sewage treatment plants (STPs). Nucleic acids of BPs were extracted using a CTAB-based method while a phenol-chloroform-based method was applied for STPs. Amplicon sequencing data of the 16S rRNA gene was achieved by MiSeq-technology.

Programming pH-triggered self-assembly transitions via isomerization of peptide sequence.

While the ordering of amino acids in proteins and peptide-based materials is known to affect their folding patterns and supramolecular architectures, tailoring self-assembly behavior in stimuli responsive peptides by isomerizing a peptide sequence has not been extensively explored. Here, we show that changing the position of a single hydrophobic amino acid in short amphiphilic peptides can dramatically alter their pH-triggered self-assembly transitions. Using palmitoyl-IAAAEEEE-NH2 and palmitoyl-IAAAEEEEK(DO3A:Gd)-NH2 as controls, moving the Isoleucine away from the palmitoyl tail preferentially induces nanofiber formation over spherical micelles.

Probing peptide amphiphile self-assembly in blood serum.

There has been recent interest in designing smart diagnostic or therapeutic self-assembling peptide or polymeric materials that can selectively undergo morphological transitions to accumulate at a disease site in response to specific stimuli. Developing approaches to probe these self-assembly transitions in environments that accurately amalgamate the diverse plethora of proteins, biomolecules, and salts of blood is essential for creating systems that function in vivo. Here, we have developed a fluorescence anisotropy approach to probe the pH-dependent self-assembly transition of peptide amphiphile (PA) molecules that transform from spherical micelles at pH 7.

Evaluation of presence of aspirin-related warnings with willow bark.

Background: The dietary supplement willow bark, also known simply as willow, contains salicylates that may present a safety risk to people. Current regulations do not require willow bark to include any cautions on its label.

Objective: To evaluate the absence or presence of label warnings related to salicylates contained in willow bark to ascertain whether a potentially dangerous lack of information exists.
