January 2025

Department of Restorative Dentistry, Periodontology and Endodontology, University Medicine Greifswald, Greifswald, Germany.

Background: Despite considerable improvements in oral health in recent decades, caries and periodontitis are still widespread, ranking among the most prevalent diseases worldwide and requiring future research. The German National Cohort (NAKO Gesundheitsstudie, NAKO) is a large-scaled, multidisciplinary, nationwide, multi-centre, population-based, prospective cohort study with oral examinations that aims to provide a resource to study risk factors for major diseases. The aim of the present article is to provide the methodological background, to report on the data quality, and to present initial results of the oral examinations.

Nuclear factor of activated T-cells 5 (NFAT5) is a transcription factor known for its role in osmotic stress adaptation in the renal inner medulla, due to the osmotic gradient that is generated between the renal cortex and renal inner medulla. However, its broader implications in kidney injury and chronic kidney disease (CKD) are less understood. Here we used two different Cre deleter mice (Ksp1.

Nanocrystalline formulations typically contain stabilizing additives to minimize the risk of particle growth or agglomeration. This risk is particularly relevant when the nanosuspension is converted into a solid drug product as the original state of the nanosuspension should be restored upon redispersion of the drug product in vivo. In this work, the behavior of different nonionic and anionic surfactants in solid nanocrystalline formulations and their effects on redispersibility under biorelevant conditions were investigated.

J-Lat cells are derivatives of the Jurkat CD4 T cell line that contain a non-infectious, inducible HIV provirus with a GFP tag. While these cells have substantially advanced our understanding of HIV latency, their use by many laboratories in low and middle-income countries is restricted by limited access to flow cytometry. To overcome this barrier, we describe a modified J-Lat assay using a standard microplate reader that detects HIV-GFP expression following treatment with latency-reversing agents (LRAs).

J Agric Food Chem

January 2025

Institute of Chemistry, Food Chemistry, Martin Luther University Halle-Wittenberg, Kurt-Mothes-Str. 2, 06120 Halle (Saale), Germany.

Some lactic acid bacteria such as or contain genes encoding 4,6-α-glucanotransferases. These enzymes convert starch and maltodextrins into isomalto/malto-polysaccharides (IMMPs). Many studies focused on the properties of recombinant glucanotransferases, but limited knowledge is available on fermentative synthesis.

[Multimorbid patients in endocrine surgery].

Chirurgie (Heidelb)

January 2025

Klinik für Viszerale, Gefäß- und Endokrine Chirurgie, Universitätsmedizin Halle, Ernst-Grube-Str. 40, 06120, Halle/Saale, Deutschland.

Endocrine surgery in multimorbid, frail and geriatric patients is increasing, is often urgent and characterized by special risk constellations. Successful parathyroid gland surgery nearly always results in a marked improvement, irrespective of the specific risk profile of the patient. Except for critical intubation and mediastinal interventions in the risk profile, surgery of the thyroid glands is predominantly beneficial and justifiable even in frail patients.

A significant proportion of patients who have recovered from COVID-19 suffer from persistent symptoms, referred to as "post-acute sequelae of SARS-CoV-2 infection (PASC)". Abnormal brain intrinsic activity has been observed in PASC patients, but the patterns of frequency-dependent intrinsic activity in the PASC and non-PASC (recovered COVID-19 patients without persistent symptoms) groups and their association with neuropsychiatric sequelae remain unclear in PASC. Twenty-nine PASC patients, 27 non-PASC subjects, and 31 healthy controls (HCs) were recruited.

Iron plays a prominent role in various biological processes and is an essential element in almost all organisms, including plant-pathogenic fungi. As a transition element, iron occurs in two redox states, Fe and Fe, the transition between which generates distinct reactive oxygen species (ROS) such as HO, OH anions, and toxic OH· radicals. Thus, the redox status of Fe determines ROS formation in pathogen attack and plant defense and governs the outcome of pathogenic interactions.

Peripheral neuropathy: from guidelines to clinical practise.

Curr Opin Oncol

January 2025

Department of Hematology, Oncology and Palliative Medicine, Ernst von Bergmann Hospital Potsdam, Potsdam.

Purpose Of Review: Chemotherapy-induced peripheral neuropathy (CIPN) is a substantial adverse effect of anticancer therapy. No effective preventive strategies are established in clinical routine, although some forms of cryotherapy or compression therapy seem to be promising. CIPN is difficult to grade objectively and has mostly relied on a clinician- or patient-based rating that is subjective and not easily reproducible.

Context: There are urgent calls to transition society to more sustainable trajectories, at scales ranging from local to global. Landscape sustainability (LS), or the capacity for landscapes to provide equitable access to ecosystem services essential for human wellbeing for both current and future generations, provides an operational approach to monitor these transitions. However, the complexity of landscapes complicates how and what to consider when assessing LS.

Background: Short-chain fatty acids (SCFAs), including propionic acid (PA), are key in immunological research. Supplementing PA has shown benefits for autoimmune diseases. A comprehensive understanding of the PA pharmacokinetics is essential for the optimal design and execution of studies utilizing orally administered PA.

With climate extremes' rising frequency and intensity, robust analytical tools are crucial to predict their impacts on terrestrial ecosystems. Machine learning techniques show promise but require well-structured, high-quality, and curated analysis-ready datasets. Earth observation datasets comprehensively monitor ecosystem dynamics and responses to climatic extremes, yet the data complexity can challenge the effectiveness of machine learning models.

T14diLys/DOPE Liposomes: An Innovative Option for siRNA-Based Gene Knockdown?

Pharmaceutics

December 2024

Department of Pharmaceutical Technology, Faculty of Natural Sciences I, Institute of Pharmacy, Martin Luther University Halle-Wittenberg, Kurt-Mothes-Str. 3, 06120 Halle/Saale, Germany.

Background/objectives: Bringing small interfering RNA (siRNA) into the cell cytosol to achieve specific gene silencing is an attractive but also very challenging option for improved therapies. The first step for successful siRNA delivery is the complexation with a permanent cationic or ionizable compound. This protects the negatively charged siRNA and enables transfection through the cell membrane.

Glucagon can increase the force of contraction (FOC) in, for example, canine hearts. Currently, whether glucagon can also increase the FOC via cAMP-increasing receptors in the human atrium is controversial discussed. Glucagon alone did not (up to 1 µM) raise the FOC in human right atrial preparations (HAP).

Pleural thickening can be the result of inflammation or infection but can also have a neoplastic origin. Depending on the clinical context, a pleural lesion or mass is often initially suspected of malignancy. Benign pleural tumors are rare, and their appearance on ultrasound (US) is also described less frequently than pleural metastases or malignancies.

Transplanted organs are inevitably exposed to ischemia-reperfusion (IR) injury, which is known to cause graft dysfunction. Functional and structural changes that follow IR tissue injury are mediated by neutrophils through the production of oxygen-derived free radicals, as well as from degranulation which entails the release of proteases and other pro-inflammatory mediators. Neutrophil serine proteases (NSPs) are believed to be the principal triggers of post-ischemic reperfusion damage.
