Self-Evaluation: Self-Enhancement and Self-Verification03:00

Self-Evaluation: Self-Enhancement and Self-Verification

5.7K
Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

Bioavailability Enhancement: Drug Solubility Enhancement

226
Body:Bioavailability is a critical factor in determining a drug's effectiveness. It refers to the proportion of a drug that enters the circulation when introduced into the body and is, as a result, able to have an active effect. Enhancing bioavailability is essential for drugs with poor solubility, as it can significantly impact their therapeutic efficacy. Various methods are employed to increase the solubility of drugs, thereby enhancing their bioavailability.Micronization and nanonization are...

Bioavailability Enhancement: Drug Permeability Enhancement

193
Body:After oral administration, poor permeability often limits the rate at which drugs are absorbed through the intestinal epithelium. Enhancing drug permeability is crucial for effective therapy, and several strategies have been developed to overcome this challenge.One effective strategy involves the use of lipid-based formulations. These formulations enhance dissolution and solubility, targeting physiological mechanisms to increase drug absorption. This includes stimulating bile salt...

Bioavailability Enhancement: Drug Stability Enhancement and GI Retention

202
Body:Improving a drug's stability in the gastrointestinal (GI) tract is paramount for enhancing its bioavailability and therapeutic effectiveness. Various strategies are employed to protect the drug from the harsh gastric milieu and to ensure its release and absorption at the desired site within the GI tract.Polymer coatings are one such method used to shield drugs from the stomach's acidic environment. By preventing premature drug release, these coatings improve the bioavailability of unstable...

MOSFET: Enhancement Mode01:22

MOSFET: Enhancement Mode

801
Enhancement-mode MOSFETs are pivotal components in electronics, distinguished by their capacity to act as highly efficient switches. They are part of the larger family of metal-oxide Semiconductor Field-Effect Transistors (MOSFETs). They are available in two types: p-channel and n-channel, each tailored to specific polarity operations.
In their basic form, enhancement-mode MOSFETs are typically non-conductive when the gate-source voltage (Vgs) is zero. This default 'off' state means no...

Enhanced Elimination of Poison01:26

Enhanced Elimination of Poison

876
Poison can be effectively removed from the gastrointestinal (GI) tract through various decontamination procedures.
Antidotes serve a crucial role in counteracting the effects of poison by inhibiting enzymes responsible for producing harmful drug metabolites. In some cases, these toxic metabolites can be neutralized by endogenous cosubstrates, which are maintained at specific concentrations to prevent interaction with cellular macromolecules and subsequent cell death.
Renal excretion is the...

Area of Science:

  • Neuro-oncology
  • Medical Image Analysis
  • Artificial Intelligence

Background:

  • Manual delineation of brain tumors in MRI is time-consuming and challenging due to image variations.
  • Accurate tumor segmentation is crucial for diagnosis, treatment planning, and surveillance in neuro-oncology.

Purpose of the Study:

  • To develop and evaluate a novel computer-assisted image segmentation framework for brain tumor delineation.
  • To improve the accuracy and efficiency of segmenting intra-tumoral structures and glioma sub-regions.

Main Methods:

  • Proposed a framework combining Inception modules with the U-Net architecture for brain tumor segmentation.
  • Implemented two learning regimes: segmenting intra-tumoral structures or glioma sub-regions, using a Dice similarity coefficient (DSC)-based loss function.

Main Results:

  • Incorporating Inception modules significantly improved segmentation performance for all glioma sub-regions (p < 0.001).
  • Models trained for intra-tumoral structure segmentation outperformed those for glioma sub-regions in whole tumor segmentation (p < 0.001).

Conclusions:

  • The proposed framework enhances brain tumor segmentation accuracy through multiscale feature extraction and a modified loss function.
  • The combination of Inception modules and U-Net architecture offers a promising approach for automated neuro-oncology image analysis.
