Nucleosome Remodeling02:54

Nucleosome Remodeling

11.1K
Nucleosomes are the basic units of chromatin compaction. Each nucleosome consists of the DNA bound tightly around a histone core, which makes the DNA inaccessible to DNA binding proteins such as DNA polymerase and RNA polymerase. Hence, the fundamental problem is to ensure access to DNA when appropriate, despite the compact and protective chromatin structure.

Eukaryotic cells have specialized enzymes called ATP-dependent nucleosome remodeling enzymes. These enzymes...

Types of Biopharmaceutical Studies: Controlled and Non-Controlled Approaches

427
Biopharmaceutical studies constitute a vital field aiming to enhance drug delivery methods and refine therapeutic approaches, drawing upon diverse interdisciplinary knowledge. In research methodologies, the choice between controlled and non-controlled studies significantly influences the study's reliability and accuracy.
Non-controlled studies, commonly employed for initial exploration, lack a control group, rendering them susceptible to biases and external influences. In contrast,...

Bone Remodeling01:40

Bone Remodeling

40.4K
Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.

Osteoclasts in Bone Remodeling01:31

Osteoclasts in Bone Remodeling

4.1K
Osteoclasts are cells responsible for bone resorption and remodeling. They originate from hematopoietic progenitor cells present in the bone marrow. Numerous progenitor cells fuse to form multinucleated cells, each with 10-20 nuclei. A single osteoclast has a diameter of 150 to 200 µM. These cells have ruffled borders that break down the underlying bone tissue and release minerals such as calcium into the blood in bone resorption. Osteoclasts cling to bones with their ruffled edges during...

Control System Problem01:21

Control System Problem

423
In an open-loop system, such as a basic thermostat, the poles of the transfer function influence the system's response but do not determine its stability. However, when feedback is introduced to form a closed-loop system, such as an advanced thermostat that adjusts heating based on room temperature, stability is governed by the new poles of the closed-loop transfer function.
When forming a closed-loop system, issues can arise if the poles cross into the unstable region, leading to potential...

Combinatorial Gene Control02:33

Combinatorial Gene Control

9.6K
Combinatorial gene control is the synergistic action of several transcriptional factors to regulate the expression of a single gene. The absence of one or more of these factors may lead to a significant difference in the level of gene expression or repression.
The expression of more than 30,000 genes is controlled by approximately 2000-3000 transcription factors. This is possible because a single transcription factor can recognize more than one regulatory sequence. The specificity in gene...

Summary

This study found that while pharmacological therapy for temporo-mandibular disorders (TMD) did not alter condylar cortication, it did accelerate symptom resolution. Further research is needed to validate these findings on TMD treatment outcomes.

Area of Science:

  • Dentistry
  • Orthodontics
  • Radiology

Background:

  • Temporo-mandibular disorders (TMD) encompass various clinical issues affecting masticatory muscles and the temporo-mandibular joint (TMJ).
  • TMD diagnosis relies on clinical symptoms, with primary dysfunction linked to predisposition, stress, occlusal instability, and poor tissue adaptation.
  • Secondary TMD can stem from systemic diseases, including rheumatic, autoimmune, and tumoral conditions.

Purpose of the Study:

  • To compare the effects of two therapeutic protocols on condylar cortication and pain reduction in TMD patients.
  • To evaluate the impact of splint therapy versus combined splint and pharmacological therapy on TMD symptoms and radiographic changes.

Main Methods:

  • A case-control study involving 20 TMD patients, utilizing dental casts, CO-CR discrepancy index (CPI) evaluation, and cone-beam computed tomography (CBCT).
  • Radiographic evaluation of condylar cortication was performed before and after treatment using CBCT.
  • Two protocols were compared: Protocol 1 (N.=10) with exclusive splint use, and Protocol 2 (N.=10) with splint plus pharmacological therapy (NSAIDs, antioxidant, omega-3). Pain was assessed using the Visual Analogue Scale (VAS).

Main Results:

  • No significant differences in condylar cortication were observed between the two therapeutic protocols.
  • Pharmacological therapy, when combined with splint use, led to a significantly faster resolution of symptoms (P=0.00001 at 10 days, P=0.0251 at 3 months).

Conclusions:

  • Pharmacological interventions in TMD therapy do not appear to influence condylar cortication.
  • Medicaments may expedite symptom relief in TMD patients, but further research is required to confirm these observations.
