Numerical modeling of hydrogel scaffold anisotropy during extrusion-based 3D printing for tissue engineering.

Extrusion-based 3D printing is a widely utilized tool in tissue engineering, offering precise 3D control of bioinks to construct organ-sized biomaterial objects with hierarchically organized cellularized scaffolds. Topological properties in flowing polymers are determined by macromolecule conformation, namely orientation and stretch degree. We utilized the micro-macro approach to describe hydrogel macromolecule orientation during extrusion, offering a two-scale fluid behavior description.

Molecular and niche modeling approaches to identify potential amplifying hosts for an emerging tick-borne pathogen, Rickettsia rickettsii subsp. californica, the causative agent of Pacific Coast tick fever.

Pacific Coast tick fever is a recently described zoonotic disease in California caused by a spotted fever group rickettsia, Rickettsia rickettsii subsp. californica (formerly Rickettsia 364D) and transmitted by the Pacific Coast tick, Dermacentor occidentalis. Like many emerging vector-borne diseases, knowledge regarding the transmission cycle, contribution from potential amplifying hosts, and geographic distribution of R.

Lonafarnib Protects Against Muscle Atrophy Induced by Dexamethasone.

Background: Muscle atrophy, including glucocorticoid-induced muscle wasting from treatments such as dexamethasone (DEX), results in significant reductions in muscle mass, strength and function. This study investigates the potential of lonafarnib, a farnesyltransferase inhibitor, to counteract DEX-induced muscle atrophy by targeting key signalling pathways.

Methods: We utilized in vitro models with C2C12 myotubes treated with DEX and in vivo models with Caenorhabditis elegans and DEX-treated Sprague-Dawley rats.

The main goal of this study was to investigate the effect of lead (Pb) at various concentrations, as an abiotic factor, and the cross-talk between Pb and pea aphid ( (Harris)) (Hemiptera: Aphididae), as a biotic factor, on the defence responses of pea seedlings ( L. cv. Cysterski).

The roles of habitat isolation, landscape connectivity and host community in tick-borne pathogen ecology.

Habitat loss and forest fragmentation are often linked to increased pathogen transmission, but the extent to which habitat isolation and landscape connectivity affect disease dynamics through movement of disease vectors and reservoir hosts has not been well examined. Tick-borne diseases are the most prevalent vector-borne diseases in the United States and on the West Coast, is one of the most epidemiologically important vectors. We investigated the impacts of habitat fragmentation on pathogens transmitted by and sought to disentangle the effects of wildlife communities and landscape metrics predictive of pathogen diversity, prevalence and distribution.

A Study of Enhancing Federated Learning on Non-IID Data with Server Learning.

Federated Learning (FL) has emerged as a means of distributed learning using local data stored at clients with a coordinating server. Recent studies showed that FL can suffer from poor performance and slower convergence when training data at the clients are not independent and identically distributed (IID). Here, we consider auxiliary server learning as a approach to improving the performance of FL on non-IID data.

Health-related quality of life of people with depression: pre-post intervention compared with age-matched general population in Vietnam.

Background: In Vietnam, there is a paucity of health-related quality of life (HRQoL) research on people with depression as well as a lack of evidence on supported self-management (SSM) intervention for depression on HRQoL. This study aimed to compare the HRQoL of people with depression and age-matched people in the Vietnamese population, evaluate the effects of Tele-SSM intervention on HRQoL, and examine the association between the changes in HRQoL score and mental health well-being (depression, anxiety, and stress).

Methods: This study was a pre- and post-study involving Vietnamese adults aged 18-64 who had depression symptoms (score ≥ 5 points in the PHQ-9).

Impact of osteopathic manipulative medicine training during graduate medical education and its integration into clinical practice.

Context: Osteopathic manipulative medicine (OMM) is a unique skill set consisting of physical manipulations that treat the neuromusculoskeletal system. Although OMM can improve patient outcomes such as functionality and pain, as well as increase physician reimbursement, its use is declining. Barriers to its use include a lack of proficiency, support, reimbursement, and time.

Diagnostic Accuracy of Ultrasound Guidance in Transthoracic Needle Biopsy: A Systematic Review and Meta-Analysis.

Purpose: To perform a systematic review and meta-analysis of relevant studies to assess the diagnostic accuracy and safety outcomes of ultrasound (US)-guided transthoracic needle biopsy (TTNB) for peripheral lung and pleural lesions.

Materials And Methods: A search was performed through Medline, Embase, Web of Science, and Cochrane Central from inception up to September 23, 2022 for diagnostic accuracy studies reporting US-guided TTNB (Prospero registration: CRD42021225168). The primary outcome was diagnostic accuracy, which was assessed by sensitivity, specificity, likelihood ratios (LR), and diagnostic odds ratio.

In Vitro and In Silico Analysis of PTP1B Inhibitors from Leaves and Their Effect on Glucose Uptake.

As part of our ongoing research on new anti-diabetic compounds from ethnopharmacologically consumed plants, two previously undescribed lupane-type triterpenoids ( and ) with dicarboxylic groups, an undescribed nor-taraxastane-type triterpenoid (), and 14 known compounds (-) were isolated from the leaves of . Extensive spectroscopic analysis (IR, HRESIMS, 1D, and 2D NMR) was used for structure elucidation, while the known compounds were compared to reference data reported in the scientific literature. All the isolates (-) were evaluated for their inhibitory effects on the protein tyrosine phosphatase 1B (PTP1B) enzyme.

Cost-effectiveness of consolidation durvalumab for inoperable stage III non-small cell lung cancer in Vietnam.

Background: This study aimed to assess the cost-effectiveness of durvalumab as a treatment option for patients with inoperable stage III non-small cell lung cancer (NSCLC) from healthcare and partial societal perspectives in Vietnam.

Method: A lifetime partitioned survival model was used to evaluate the costs and quality-adjusted life years (QALYs) associated with consolidation durvalumab in comparison with the standard of care alone. Local costs and utilities were incorporated into the model.

Calcified carotid artery atheroma on standard dental radiographs: A public health opportunity for cardiovascular risk reduction.

Objective: Calcified carotid artery atheroma (CCAA) can be identified incidentally on standard dental panoramic radiographs (DPRs).

Inhibition of protein tyrosine phosphatase 1B by serratane triterpenes from Huperzia serrata and their molecular docking study.

During the search for protein tyrosine phosphatase 1B (PTP1B) inhibitory compounds from the natural resources, two new serratane triterpenes, 3-O-dihydro-p-coumaroyltohogenol (1) and 21-O-acetyltohogenol (2), along with four known serratane triterpenes (3-6), were isolated from the whole plant of Huperzia serrata. The chemical structures of compounds 1 and 2 were determined by NMR study, HRMS analysis, and chemical modification. All isolates were evaluated for their PTP1B inhibitory activities.

Chronic obstructive pulmonary disease exacerbation purulence status and its association with pulmonary embolism: protocol for a systematic review with meta-analysis.

Introduction: Acute exacerbation of chronic obstructive pulmonary disease (AECOPD) increases the risk of pulmonary embolism (PE). AECOPD and PE have similar symptoms which results in a high proportion of patients with AECOPD undergoing imaging to rule out PE. Finding predictors and explanatory factors of PE in AECOPD, such as purulence status, could help reduce the need for imaging.

Managing Pulmonary Arterial Hypertension With Cardiopulmonary Comorbidities.

Pulmonary arterial hypertension (PAH) and pulmonary hypertension associated with left-sided heart and lung diseases are most commonly easily discriminated and treated accordingly. With the changing epidemiology of PAH, however, a growing proportion of patients at the time of diagnosis present with comorbidities of varying severity. In addition to classical PAH, two distinct phenotypes have emerged: a heart failure with preserved ejection fraction-like phenotype and a lung phenotype.
