Soft tissue deficiency around dental implants can negatively impact outcomes in terms of esthetics and long-term stability. While autogenous connective tissue grafting is still considered the gold standard treatment, alternative approaches are being proposed primarily to enhance patient comfort and avoid invasive procedures such as two-sites surgeries using xenogeneic collagen matrices. Despite the advantages, the quality of the regenerated tissues remains unpredictable and, in many cases, questionable, highlighting the need for alternative and innovative approaches.

Altered Neural Responses to Punishment Learning in Conduct Disorder.

Biol Psychiatry Cogn Neurosci Neuroimaging

January 2025

Department of Child and Adolescent Psychiatry, Faculty of Medicine, TUD Dresden University of Technology, German Center for Child and Adolescent Health (DZKJ), partner site Leipzig/Dresden, Dresden, Germany.

Objective: Conduct disorder (CD) is associated with deficits in the use of punishment for reinforcement learning (RL) and subsequent decision-making, contributing to reckless, antisocial, and aggressive behaviors. Here, we used functional magnetic resonance imaging (fMRI) to examine whether differences in behavioral learning rates derived from computational modeling, particularly for punishment, are reflected in aberrant neural responses in youths with CD compared to typically-developing controls (TDCs).

Methods: 75 youths with CD and 99 TDCs (9-18 years, 47% girls) performed a probabilistic RL task with punishment, reward, and neutral contingencies.

Previous analyses provide an industry benchmark of ∼10% for the success rate in clinical development. However, prior analyses were limited by a narrow timeframe, a diverse research focus, biases in phase-to-phase transition methodology or a focus on specific use cases. We calculated unbiased input:output ratios (Phase I to FDA new drug approval) to analyze the likelihood of first approval using data from clinicaltrials.

The frozen storage of biopharmaceuticals brings new challenges to the primary packaging material. Due to an increasing demand and the downsides of standard type I glass vials, such as vial breakage, novel vial types for special applications of parenteral drug products have been introduced to the market in the past years. Mechanical stresses due to dimensional changes experienced during freezing and thawing could change the material properties, hence affecting the interaction with the drug product stored in the vial or functionality such as overall integrity.

Adeno-associated virus (AAV)-based vectors have emerged as an effective and widely used technology for somatic gene therapy approaches, including those targeting the retina. A major advantage of the AAV technology is the availability of a large number of serotypes that have either been isolated from nature or produced in the laboratory. These serotypes have different properties in terms of sensitivity to neutralizing antibodies, cellular transduction profile and efficiency.

Primary human hepatocytes (PHHs) are the preferred cell source to address liver function. Despite originating from the native tissue, one of the bottlenecks when using primary material is the donor-to-donor variability. Cryopreserved PHHs offer a high number of cells from the same donor and standardization of cell isolation and cryopreservation procedures, mitigating some of the inter-donor variability.

Division of Clinical Epidemiology and Aging Research, German Cancer Research Center, Im Neuenheimer Feld 581, 69120 Heidelberg, Germany. Electronic address:

Efforts to reduce preventable medication-related harm through medication reviews have increased, but interventions often yield null-results regarding clinical outcomes. We conducted a systematic literature search in four data bases and summarised the available evidence from randomised controlled trials (RCTs) comparing medication reviews and usual care in hospitalised patients regarding hospital readmissions and all-cause mortality by random-effects meta-analyses. Effect size differences by methodological study differences were of special interest.

Human chitinolytic enzymes trigger growing interest, not only because a wide range of diseases and allergic responses are linked to chitinous components of pathogens, including their interplay with human enzymes, but also due to the increasing use of chitosans in biomedical applications. Here, we present a detailed side-by-side analysis of the only two human chitinases, chitotriosidase and acidic mammalian chitinase, as well as human lysozyme. By analyzing the cleavage of well-characterized chitosan polymers and defined chitin and chitosan oligomers, we report mild processivity and a quantitative subsite preference typical for GH18 chitinases for chitotriosidase and acidic mammalian chitinase.

Roles of acyl carrier proteins in ladderane fatty acid producing-organisms.

Biochim Biophys Acta Gen Subj

January 2025

Department of Biomolecular Mechanisms, Max Planck Institute for Medical Research, Jahnstrasse 29, D-69120 Heidelberg, Germany. Electronic address:

Ladderanes are highly strained hydrocarbons consisting of two or more linearly concatenated cyclobutane rings. Strikingly, ladderane moieties are part of unique fatty acids and fatty alcohols that are exclusively found in the membrane lipids of anaerobic ammonium-oxidizing (anammox) bacteria. These bacteria express a distinctive gene cluster (cluster I) that has been suggested to be responsible for ladderane fatty acid (FA) biosynthesis in addition to a cluster likely involved in canonical FA biosynthesis (cluster III).

An ulnar nerve (UN) palsy is devastating for hand function, resulting in an intrinsic minus position or claw hand with a loss of pinch grip. Distal nerve transfers facilitate faster reinnervation of hand intrinsic muscles in cases of proximal ulnar nerve lesions. The traditional anterior interosseous nerve (AIN) to UN motor transfer is commonly used, however, this still leads to long reinnervation times for the distal intrinsic muscles, important for the thumb to index pinch grip.
