Wnt-Dependent Ontogeny Of Acellular Cementum-Forming Cementoblasts On The Tooth Root Surface, Taishi Komori, Mizuki Nagata, Natnicha Praneetpong, Hanwen Fan, Yuxiao Zhou, Noriaki Ono, Wanida Ono

Faculty, Staff and Student Publications

Cementum is a specialized mineralized tissue that covers the tooth root surface and anchors the tooth to the surrounding periodontal ligament. The cervical acellular cementum (AC) is indispensable for periodontal attachment and represents a key target for periodontal regenerative therapies. However, the developmental origin and molecular identity of AC-forming cementoblasts remain poorly understood. Here, through an integrated spatial and single-cell transcriptomic analysis, we identify AC-forming cementoblasts as a distinct population of noncanonical mineralizing cells enriched for cell-matrix organization and Wnt signaling signatures, distinguishing them from cellular cementum-forming cementoblasts localized in the apical portion. Lineage tracing using a Wnt inhibitory factor …

Stress and diet are known to synergistically promote risks of obesity but the underlying neural basis remains elusive. Corticotropin-releasing hormone neurons in the paraventricular hypothalamus (PVHCRH) are stress responsive and release both CRH and glutamate. Here we generated a mouse model with gain or loss of release in CRH or glutamate from PVHCRH neurons. While these models showed no changes in body weight when fed chow, they exhibited contrasting effects when fed high-fat high-caloric diets (HFD). Whereas disrupting glutamate release from PVHCRH neurons led to diet-induced obesity (DIO), that of CRH caused no impact. Conversely, augmented CRH release led to …

Early Detection Of Alzheimer's Disease And Related Dementias From Spontaneous Speech Using Foundation Speech And Language Models: Comparative Evaluation, Jingyu Li, Lingchao Mao, Xi Mao, Hairong Wang, Zhendong Wang, Xuelei Sherry Ni

School of Economics and Finance Faculty Publications

Background: Alzheimer's disease and related dementias (ADRD) are progressive neurodegenerative conditions where early detection is critical for timely intervention and care planning. However, current diagnostic methods are often inaccessible, costly, and delayed, especially for underserved populations. There is a growing need for scalable, noninvasive tools that can support timely diagnosis. Spontaneous speech contains rich acoustic and linguistic markers that can serve as noninvasive behavioral markers for cognitive decline. Foundation models, pretrained on large-scale audio or text data, generate high-dimensional embeddings that encode rich contextual and acoustic information.

Objective: This study benchmarks open-source foundation language and speech models to evaluate their …

Global reporting of obesity is commonly based on comparisons over multiple decades1 and lacks a granular and systematic analysis of its dynamics. We used 4,050 population-based studies with measured height and weight data on 232 million participants to assess the worldwide dynamics of obesity from 1980 to 2024. The rise in obesity decelerated in school-aged children and adolescents throughout the 1990s in many high-income countries, and subsequently plateaued in most at age-standardized prevalences spanning 20 percentage points, from 3–4% for girls in Japan, Denmark and France to 23% for boys in the USA. There were indications of a small …

Hierarchical Small Molecule Inhibition Of Myst Acetyltransferases, Xuemin Chen, Alexandra Castroverde, Minervo Perez, Ronald Holewinski, Kiall F Suazo, Rashmi Karki, Thorkell Andresson, Benjamin A Garcia, Jordan L Meier

2020-Current year OA Pubs

MYST lysine acetyltransferases (KATs) are a class of epigenetic enzymes critical for cellular function that constitute an emerging therapeutic target in cancer. Recently, several drug-like MYST inhibitors have been reported that show promise in preclinical models as well as in clinical trials of breast cancer. Understanding the specificity of these molecules is critical for their effective use as chemical probes. Here we apply an integrated profiling strategy to systematically define the potency and selectivity of drug-like MYST KAT inhibitors. First, we use optimized chemoproteomic profiling and histone acetylation biormarkers to study the industry-developed KAT inhibitor PF-9363. This reveals dose-dependent engagement …

Wireless communication technologies for bioelectronic implants enable remote monitoring for diagnosis and adaptive therapeutic intervention without the constraints of wired connections. However, wireless data uplink from millimeter-scale devices deep in the body struggles to achieve low power consumption while maintaining large misalignment tolerances. Here, we report a passive wireless backscatter communication system based on magnetoelectric transducers that consumes less than 0.3 pJ/bit and achieves less than 1E-6 bit error rate at a distance of 55 mm while tolerating a misalignment of 10 mm. Using this robust data uplink, we designed a wireless cardiac sensing node that can transmit electrocardiogram signals …

Phosphate-Mediated Regulation Of Intracellular Calcium Dynamics, Huma Shahzad, Mohammed S. Razzaque

School of Medicine Publications

Phosphate (Pi) and calcium (Ca2+) are essential mineral ions that play coordinated roles in maintaining normal cellular functions. While various steps of calcium signaling are well characterized, emerging evidence suggests the critical role of both intracellular and extra cellular phosphate in regulating intracellular Ca2+. In the cytoplasm, phosphate influences ATP production and organelle calcium buffering and influences the activity of calcium pumps, such as sarcoplasmic/endoplasmic reticulum Ca2+-ATPase (SERCA) and the plasma membrane Ca2+-ATPase (PMCA). Extracellular phosphate, taken up via sodium-dependent phosphate transporters, triggers signaling cascades that affect the processes of calcium influx, storage, and release. Additionally, high extracellular phosphate levels …

Abl Kinases Regulate Fgf Signaling Independent Of Crk Phosphorylation To Prevent Peters Anomaly Type Ii, Hao Wu, Yingyu Mao, Qian Wang, Honglian Yu, Michael Bouaziz, Neoklis Makrides, Enpeng Wang, Zhipeng Ding, Anthony J Koleske, Glenn L Radice, Jerry Hsu, Xin Zhang

2020-Current year OA Pubs

Peters anomaly is an anterior segment dysgenesis and a leading cause of congenital corneal opacity. Here, we show that loss of ABL kinases restores lens induction in the absence of FGF signaling but induces Peters anomaly type II independently of ERK signaling, a phenotype also observed with elevated FGF-Ras activity. This defect is rescued by allelic deletion of the ABL substrates CRK and CRKL. Contrary to prevailing models, ABL kinases do not act through direct phosphorylation of CRK proteins; instead, they phosphorylate PTPN12, suppressing p130CAS phosphorylation and CRK recruitment required for RHO GTPase activation. ABL kinase deficiency reduces actomyosin contractility …

This study aimed to establish normal two-dimensional, M-mode, and Doppler echocardiographic values in healthy conscious Syrian hamsters and to evaluate the influence of age, body weight, and sex on cardiac parameters. Forty Syrian hamsters (27 males and 12 females; one excluded) underwent physical examination, thoracic radiography, and echocardiography. Age and body weight were recorded. Echocardiographic parameters were analyzed for their distribution and correlation with age and body weight. All echocardiographic parameters demonstrated a …

Assessment Of Platelet Activation In Dogs With Naturally Occurring Acute Pancreatitis, Guhyun Kwon, Seulgi Bae

The Thai Journal of Veterinary Medicine

Recent studies have demonstrated that platelets are crucial in inflammation and immune responses. Alteration in platelet activity impact morbidity and survival due to the formation of intravascular clots or bleeding resulting from impaired platelet function. Aiming to evaluate changes in platelet activity in dogs with naturally occurring acute pancreatitis (AP), we identified differences in quantitative and morphological platelet indices, as well as the ratio of platelets expressing P-selectin on their surface (activated platelet ratio; APR) between dogs with naturally occurring AP and healthy dogs. The study included 9 client-owned dogs with AP (the AP group) and 28 client-owned healthy dogs …

Dissociation Between Physical Reasoning And Tool Use In Individuals With Left Hemisphere Brain Damage, Shuchen Liu, Seda Karakose-Akbiyik, Alfonso Caramazza, Filipa Dourado Sotero, Laurel J. Buxbaum, Aaron L. Wong

Moss-Magee Rehabilitation Papers

Tool use and physical reasoning are often assumed to rely on shared cognitive and neural mechanisms. At some level, this correspondence is expected: using an object typically requires understanding its physical properties. However, both capacities are complex and multicomponential, so the relationship between them may vary across levels of representation and task demands. Here, we asked whether third-person physical reasoning about object dynamics can dissociate from tool use (i.e., performing a tool's typical action) in individuals with left-hemisphere stroke. We tested 11 patients, five of whom showed impairments in tool use. Physical reasoning was assessed using a novel collection of …
