Hydrogel Encapsulation Techniques and Its Clinical Applications in Drug Delivery and Regenerative Medicine: A Systematic Review.

Hydrogel encapsulation is a promising carrier for cell and drug delivery due to its ability to protect the encapsulated entities from harsh physiological conditions and enhance their therapeutic efficacy and bioavailability. However, there is not yet consensus on the optimal hydrogel type, encapsulation method, and clinical application. Therefore, a systematic review of hydrogel encapsulation techniques and their potential for clinical application is needed to provide a comprehensive and up-to-date overview.

Cancer stem cell-derived exosomes in CD8 T cell exhaustion.

Tumor-derived extracellular vesicles (EVs) are one of the most important ways of intercellular communication and signaling. Cancer stem cells (CSCs) secrete EVs to modulate immune checkpoint molecules and evade immune surveillance. Activated CD8 T cells known as cytotoxic T lymphocytes (CTLs) are the most powerful anti-cancer adaptive cells.

The Effect of Lower Limb Position on Anterior Cruciate Ligament Reconstruction on Uncommon Complications after Surgery.

Background: To reduce the complications of orthopedic surgery, the desire for less invasive procedures, such as, knee arthroscopy to repair the anterior cruciate ligament, has increased. There are, currently, two common positions for limbs that are used during surgery depending on the surgeon's experience. Therefore, our aim was to investigate the effect of limb position on complications after anterior cruciate ligament reconstruction surgery.

Epigenetic drugs as new emerging therapeutics: What is the scale's orientation of application and challenges?

Epigenetics is the study of heritable changes in gene expression or function without altering the DNA sequence. Important factors are part of epigenetic events, such as methylation, DNA histone rearrangements, nucleosome transposition, and non-coding RNAs. Dysregulated epigenetic mechanics are associated with various cancers' initiation, development, and metastasis.

Cellular and molecular basis of therapeutic approaches to breast cancer.

In recent decades, there has been a significant amount of research into breast cancer, with some important breakthroughs in the treatment of both primary and metastatic breast cancers. It's a well-known fact that treating breast cancer is still a challenging endeavour even though physicians have a fantastic toolset of the latest treatment options at their disposal. Due to limitations of current clinical treatment options, traditional chemotherapeutic drugs, and surgical options are still required to address this condition.

Specific pattern of bone scan as a result of unintentional-intraarterial injection into the ulnar artery.

Background: Bone scintigraphy with 99mTc labeled radiopharmaceuticals is a valuable method in nuclear medicine for assessing the bony structure. In clinical setting, bone scintigraphy is accomplished after the injection of 99mTc labeled diphosphonate complexes into a peripheral vein. Inadvertent intra-arterial injection on the antecubital region may cause a special form of artifacts leading to problems inaccurately interpreting these studies as functional images.

Applications and Techniques for Fast Machine Learning in Science.

In this community review report, we discuss applications and techniques for machine learning (ML) in science-the concept of integrating powerful ML methods into the real-time experimental data processing loop to accelerate scientific discovery. The material for the report builds on two workshops held by the Fast ML for Science community and covers three main areas: applications for fast ML across a number of scientific domains; techniques for training and implementing performant and resource-efficient ML algorithms; and computing architectures, platforms, and technologies for deploying these algorithms. We also present overlapping challenges across the multiple scientific domains where common solutions can be found.

The efficacy of melatonin against radiotoxicity of iodine-131 and its response to treatment in hyperthyroid patients: a randomized controlled trial.

Background: Since melatonin is a non-toxic compound with proven radioprotective effects, we aimed to investigate its efficacy in an in-vivo setting in hyperthyroid patients who are treated with iodine-131. This double-blind placebo-controlled study was conducted on hyperthyroid patients referred to nuclear medicine centers in Babol, Iran. We excluded patients suffering from hypertension treated with warfarin, autoimmune diseases, genetic diseases, cancers, smokers, chemical wounded, radiology and radiotherapy workers, and those who were treated with chemotherapy agents.

Coupling brain-tumor biophysical models and diffeomorphic image registration.

We present SIBIA (Scalable Integrated Biophysics-based Image Analysis), a framework for joint image registration and biophysical inversion and we apply it to analyze MR images of glioblastomas (primary brain tumors). We have two applications in mind. The first one is normal-to-abnormal image registration in the presence of tumor-induced topology differences.

Simulation of glioblastoma growth using a 3D multispecies tumor model with mass effect.

In this article, we present a multispecies reaction-advection-diffusion partial differential equation coupled with linear elasticity for modeling tumor growth. The model aims to capture the phenomenological features of glioblastoma multiforme observed in magnetic resonance imaging (MRI) scans. These include enhancing and necrotic tumor structures, brain edema and the so-called "mass effect", a term-of-art that refers to the deformation of brain tissue due to the presence of the tumor.

CLAIRE: A DISTRIBUTED-MEMORY SOLVER FOR CONSTRAINED LARGE DEFORMATION DIFFEOMORPHIC IMAGE REGISTRATION.

With this work we release CLAIRE, a distributed-memory implementation of an effective solver for constrained large deformation diifeomorphic image registration problems in three dimensions. We consider an optimal control formulation. We invert for a stationary velocity field that parameterizes the deformation map.

The assessment of radio-adaptive response in graves' hyperthyroidism patients following radioactive iodine uptake.

Low doses of radiation affect the response of cells to higher doses; this phenomenon is called radio-adaptive response, which leads to increased resistance to subsequent higher doses. We have investigated the adaptive response using 0.37 MBq priming dose of I-131 followed by 296-444 MBq challenging dose in peripheral human lymphocyte cells.

Estimating the population dose from nuclear medicine examinations towards establishing diagnostic reference levels.

Purpose Of The Study: This study conducted a review on nuclear medicine (NM) services in Mazandaran Province with a view to establish adult diagnostic reference levels (DRLs) and provide updated data on population radiation exposure resulting from diagnostic NM procedures.

Materials And Methods: The data were collected from all centers in all cities of Mazandaran Province in the North of Iran from March 2014 to February 2015. The 75(th) percentile of the distribution and the average administered activity (AAA) were calculated and the average effective dose per examination, collective effective dose to the population and annual effective dose per capita were estimated using dose conversion factors.

An inverse problem formulation for parameter estimation of a reaction-diffusion model of low grade gliomas.

We present a numerical scheme for solving a parameter estimation problem for a model of low-grade glioma growth. Our goal is to estimate the spatial distribution of tumor concentration, as well as the magnitude of anisotropic tumor diffusion. We use a constrained optimization formulation with a reaction-diffusion model that results in a system of nonlinear partial differential equations.
