Alzheimers Dement

December 2024

Memory and Aging Center, UCSF Weill Institute for Neurosciences, University of California, San Francisco, San Francisco, CA, USA.

Background: The Uniform Data Set (UDS) neuropsychological battery, administered across Alzheimer's Disease Centers (ADC), includes memory tests but lacks a list-learning paradigm. ADCs often supplement the UDS with their own preferred list-learning task. Given the importance of list-learning for characterizing memory, we aimed to develop a harmonized memory score that incorporates UDS memory tests while allowing centers to contribute differing list-learning tasks.

The utilization of β-fluoroamines as pharmaceutical components for drug development has attracted a considerable amount of interest. However, direct access to tertiary β-fluoroamines is challenging. We herein report the rhodium-catalyzed asymmetric amination of tertiary allylic trichloroacetimidates with anilines and cyclic aliphatic amines to access tertiary β-fluoroamines, where the α-carbon atom is bonded to four different substituents, in good yield with high levels of enantioselectivity.

This essay focuses on the ethical considerations and implications of providing a universal multi-cancer screening test as the best approach to reduce societal cancer burden in a society with limited funds, resources, and infrastructure. With 1.9 million cancer diagnoses each year in the United States, with 86% of all cancers diagnosed in individuals over the age of 50, and with screening tools approved for only four cancer types (breast, cervical, colorectal, and lung cancer), it seems that a multi-cancer screening test to detect most cancer early that is easy to administer, and is accurate and cost-effective, would be worth considering.

Umbilical Cord Amniotic Membrane Graft as a Skin Substitute in Periocular Reconstruction: A Case Series.

Ophthalmic Plast Reconstr Surg

January 2025

Kahana Oculoplastic and Orbital Surgery, Livonia, Michigan.

Loss of periocular skin due to cancer, trauma, or surgery is a major reconstructive challenge; resultant tissue contracture can cause eyelid malposition with poor functional and aesthetic outcomes. We describe the successful use of cryopreserved umbilical cord amniotic membrane as a wound covering and scaffold for periorbital anterior lamellar defects. This is a retrospective case series of 4 patients (mean 21 years, range 9-30 years, 3 male) who underwent periocular reconstruction with umbilical cord amniotic membrane of 9 different sites.

Neural Voices of Patients with Severe Brain Injury?

Camb Q Healthc Ethics

January 2025

Center for Consciousness Science, University of Michigan, Ann Arbor, MI, USA.

Studies have shown that some covertly conscious brain-injured patients, who are behaviorally unresponsive, can reply to simple questions via neuronal responses. Given the possibility of such neuronal responses, Andrew Peterson et al. have argued that there is warrant for some covertly conscious patients being included in low-stakes medical decisions using neuronal responses, which could protect and enhance their autonomy.

Population Pharmacokinetics and Pharmacodynamics of Sotalol Following Expedited Intravenous Loading in Patients With Atrial Arrhythmias.

CPT Pharmacometrics Syst Pharmacol

January 2025

Division of Clinical Pharmacology, Department of Pediatrics, Spencer Fox Eccles School of Medicine, University of Utah, Salt Lake City, Utah, USA.

Sotalol, a class III antiarrhythmic agent, is used to maintain sinus rhythm in patients with atrial fibrillation or atrial flutter (AFIB/AFL). Despite its efficacy, sotalol's use is limited by its potential to cause life-threatening ventricular arrhythmias due to QT interval prolongation. Traditionally, sotalol administration required hospitalization to monitor these risks.

Integrating Particle Motion Tracking into Thermal Gel Electrophoresis for Label-Free Sugar Sensing.

ACS Sens

January 2025

Department of Chemistry, Wayne State University, 5101 Cass Ave, Detroit, Michigan 48202, United States.

Bioanalytical sensors are adept at quantifying target analytes from complex sample matrices with high sensitivity, but their multiplexing capacity is limited. Conversely, analytical separations afford great multiplexing capacity but typically require analyte labeling to increase sensitivity. Here, we report the development of a separation-based sensor to sensitively quantify unlabeled polysaccharides using particle motion tracking within a microfluidic electrophoresis platform.

Wheeze and Crackle Discrimination Algorithm in Pneumonia Respiratory Signals.

Conf Proc (IEEE Colomb Conf Commun Comput)

August 2024

School of Electronic and Electrical Engineering, Sungkyunkwan University, South Korea.

A new pneumonia detection method is proposed to provide both pneumonia detection in respiratory sound signals and wheeze and crackle discrimination when pneumonia episodes are detected. In the proposed method, two-step hierarchy, classifying pneumonia in the first step and discriminating wheezing and crackling in the second step, is considered; the conventional pneumonia detection method is modified to improve pneumonia detection performance, while wheezing and crackling discrimination functionality is added to facilitate the application of appropriate remedies for each case. We used resampling techniques to address the imbalance in the ICBHI pneumonia dataset.

The endogenous reduction of nitrite to nitrosyl is drawing increasing attention as a protective mechanism against hypoxic injury in mammalian physiology and as an alternative source of NO, which is involved in a wide variety of biological activities. Thus, chemical mechanisms for this transformation, which are mediated by metallo proteins, are of considerable interest. The study described here examines the reactions of the biomimetic models Co(TTP)(NO) (TTP = meso-tetratolylporphyrinato dianion) and Mn(TPP)(ONO) (TPP = meso-tetraphenyl-porphyrinato dianion) in sublimated solid films with hydrogen sulfide (HS) and with ethanethiol (EtSH) at various temperatures from 77 K to room temperature using in situ infrared and optical spectroscopy.
