Department of Food Science, College of Agriculture and Life Sciences, Cornell University, Ithaca, NY 14853, USA. Electronic address:

Combined cross-linked enzyme aggregates (Combi-CLEAs) of β-Galactosidase (β-Gal) and Glucose Isomerase (GI) allow the transformation of d-lactose to lactose-fructose syrup through one-pot cascade biocatalytic reactions. Despite its promise, the low thermostability of β-Gal and high-temperature demands for GI limits this application. Trehalose is a protein-stabilizing disaccharide which has been utilized in immobilized enzyme systems to enhance protein thermostability.

Non-atherosclerotic coronary causes of myocardial infarction in women.

Prog Cardiovasc Dis

January 2025

Section of Interventional Cardiology, MedStar Washington Hospital Center, Washington, DC, United States. Electronic address:

Ischemic heart disease is the most common cardiovascular cause of death in women worldwide. Obstructive coronary atherosclerosis is the primary cause of myocardial infarction (MI), however, non-atherosclerotic mechanisms of MI, such as spontaneous coronary artery dissection, vasospasm, microvascular dysfunction, embolization, inflammation, coronary anomalies, infectious and infiltrative causes are increasingly being recognized. Emerging data suggest that women are two to five times more likely to have an MI in the absence of coronary atherosclerosis compared to men, but they continue to remain underdiagnosed and undertreated, partly due to underdiagnosis and limited understanding of these mechanisms.

To gain further insights into the importance of the unsaturated 1,4-ketoaldehyde moiety of ophiobolin A (OpA) for the potency and selectivity observed toward cancer stem cells, several derivatives were synthesized through controlled reduction and oxidations of the unsaturated aldehyde and ketone moieties. Structure elucidation of these new OpA derivatives was achieved through detailed NMR studies and comparison to OpA and known isolated congeners possessing variations in these regions. The relative stereochemistry of the newly generated stereocenters was determined by coupling constants in conjunction with conformational analyses (DFT) of the synthetic derivatives.

Both photothermal therapy (PTT) and chemodynamic therapy (CDT) are designed to focus their antitumor effect on only the tumor site, thereby minimizing unwanted severe damage to healthy tissue outside the tumor. However, each monotherapy is limited in achieving complete tumor eradication, resulting in tumor recurrence. The combination of multiple therapies may help to overcome the limitations of single therapy, improve the chances of complete tumor eradication, and reduce the risk of recurrence.

Transforming Transplantation Access: A Federal Directive for Comprehensive Pre-Waitlisting Data Collection.

Am J Transplant

January 2025

Division of Nephrology, Department of Medicine, Vagelos College of Physicians & Surgeons, Columbia University, New York, NY; Department of Epidemiology, Mailman School of Public Health, Columbia University, New York, NY.

There is substantial variation in access to transplantation across the United States that is not entirely explained by the availability of donor organs. Barriers to transplantation and variation in care among patients with end-stage organ disease exist prior to patients' placement on a transplant waiting list as well as following waitlist placement. However, there are currently no national data available to examine rates and variations in key care processes related to pre-listing, including transplant referral, evaluation, or candidate selection.

Cerclage in singleton pregnancies with no prior spontaneous PTB and short cervix: a randomized controlled trial.

Am J Obstet Gynecol MFM

January 2025

Division of Maternal Fetal Medicine, Department of Obstetrics and Gynecology, Sidney Kimmel Medical College, Thomas Jefferson University.

Background: PTB (PTB) remains a leading cause of neonatal morbidity and mortality. Cerclage for short cervical length (CL) ≤25mm in singletons with a history of spontaneous PTB is associated with decreased neonatal morbidity/mortality. Both vaginal progesterone and cerclage individually have level 1 evidence supporting benefit in prevention of PTB in pregnancies complicated by short CL, however there is a paucity of level 1 evidence regarding the potential benefit of cerclage with progesterone compared to progesterone alone for short CL ≤25mm in singletons without a history of spontaneous PTB.

Tensor neural networks for high-dimensional Fokker-Planck equations.

Neural Netw

January 2025

Division of Applied Mathematics, Brown University, Providence, RI 02912, USA; Advanced Computing, Mathematics and Data Division, Pacific Northwest National Laboratory, Richland, WA, United States. Electronic address:

We solve high-dimensional steady-state Fokker-Planck equations on the whole space by applying tensor neural networks. The tensor networks are a linear combination of tensor products of one-dimensional feedforward networks or a linear combination of several selected radial basis functions. The use of tensor feedforward networks allows us to efficiently exploit auto-differentiation (in physical variables) in major Python packages while using radial basis functions can fully avoid auto-differentiation, which is rather expensive in high dimensions.

Alzheimer's disease (AD) is pathologically marked by tau tangles and beta-amyloid (Aβ) plaques. It has been hypothesized that Aβ facilitates spread of tau outside of the medial temporal lobe (MTL), but exact mechanism of this facilitation remains unclear. We aimed to test the hypothesis that abnormal Aβ induces an increase in inter-network functional connectivity, which in turn induces early-stage tau elevation in limbic network.
