Introduction: Perioperative optimization of Crohn's disease (CD) patients is mandatory in order to ensure favorable outcomes and limit perioperative morbidity such as anastomosis-related complications. The use of perioperative tacrolimus may offer beneficial inflammatory control and improve postoperative outcome. However, it also may exhibit unwanted effects of immunosuppression on infectious complications and wound healing.

Surgical Treatment of Obstetric Plexus Lesions by Direct Coaptation Compared to Sural Nerve Graft Interposition.

 To date, there are no uniform guidelines for the treatment of obstetric plexus lesions in German-speaking countries. An end-to-end direct suture after resection of trunk neuroma is recommended for surgical treatment if tension-free coaptation is possible, whereas the use of autologous nerve grafts bridging the gap between the adaptation margins is advised by consensus if tension-free coaptation is impossible.  The aim of the study was to investigate which reconstruction strategy may provide a better recovery of motor function for patients after obstetric brachial plexus lesion.

Cochlear implantation in adults with acquired single-sided deafness improves cortical processing and comprehension of speech presented to the non-implanted ears: a longitudinal EEG study.

Former studies have established that individuals with a cochlear implant (CI) for treating single-sided deafness experience improved speech processing after implantation. However, it is not clear how each ear contributes separately to improve speech perception over time at the behavioural and neural level. In this longitudinal EEG study with four different time points, we measured neural activity in response to various temporally and spectrally degraded spoken words presented monaurally to the CI and non-CI ears (5 left and 5 right ears) in 10 single-sided CI users and 10 age- and sex-matched individuals with normal hearing.

A synthetic methodology toward π-extended porphyrin-rylenediimide conjugates.

In this work, we present a straightforward synthetic route for the preparation of functionalized β--fused porphyrins, which are subsequently connected to rylendiimides. The resulting donor-acceptor-type conjugates exhibit intriguing optical properties, such as panchromatism and profoundly bathochromically shifted absorption curves. A better understanding of the molecules' electronic structure was gained through density-functional theory calculations, which unveiled small HOMO-LUMO gaps.

Development and performance validation of an affordable and portable high-resolution darkfield polarization-sensitive multispectral imaging microscope for the assessment of radiation dermatitis and fibrosis.

Radiation therapy (RT) is widely used for cancer treatment but is found with side effects of radiation dermatitis and fibrosis thereby calling for timely assessment. Nevertheless, current clinical assessment methods are found to be subjective, prone to bias, and accompanied by variability. There is, therefore, an unmet clinical need to explore a new assessment technique, ideally portable and affordable, making it accessible to less developed regions too.

Systematic review and meta-analysis of the prognostic role of fibroblast-activation protein in gastrointestinal cancers.

Protected memristive implementations of cryptographic functions.

Memristive technology mitigates the memory wall issue in von Neumann architectures by enabling in-memory data processing. Unlike traditional complementary metal-oxide semiconductor (CMOS) technology, memristors provide a new paradigm for implementing cryptographic functions and security considerations. While prior research explores memristors for cryptographic functions and side-channel attack vulnerabilities, our study uniquely addresses memristor-oriented countermeasures.

Exploiting the lock: leveraging MiG-V's logic locking for secret-data extraction.

The MiG-V was designed for high-security applications and is the first commercially available logic-locked RISC-V processor on the market. In this context, logic locking was used to protect the RISC-V processor design during the untrusted manufacturing process by using key-driven logic gates to obfuscate the original design. Although this method defends against malicious modifications, such as hardware Trojans, logic locking's impact on the RISC-V processor's data confidentiality during runtime has not been thoroughly examined.

The formation of protein condensates (droplets) via liquid-liquid phase separation (LLPS) is a commonly observed phenomenon in vitro. Changing the environmental properties with cosolutes, molecular crowders, protein partners, temperature, pressure, etc. has been shown to favor or disfavor the formation of protein droplets by fine-tuning the water-water, water-protein, and protein-protein interactions.

Halogenated Trityl Cations as Easy-to-Access Super Electrophiles.

Herein, we present the first easy-to-access synthesis of the perfluorotrityl cation (15F+) with commercial GaCl3 and the further functionalization of the para-fluorine atoms of 15F+ via halodefluorination using trimethylsilyl halides TMSX (X = Cl, Br). This gives access to equally reactive perhalogenated trityl derivatives (p-3Cl12F+ and p-3Br12F+), which can be handled at room temperature. The impact of the para-exchange on the electronic structure is determined by NMR and UV-Vis spectroscopy.

Stimulate to Remember? The Effects of Short Burst of Transcutaneous Vagus Nerve Stimulation (taVNS) on Memory Performance and Pupil Dilation.

The decline in noradrenergic (NE) locus coeruleus (LC) function in aging is thought to be implicated in episodic memory decline. Transcutaneous auricular vagus nerve stimulation (taVNS), which supports LC function, might serve to preserve or improve memory function in aging. However, taVNS effects are generally very heterogeneous, and it is currently unclear whether taVNS has an effect on memory.
