Histone Modification02:32

Histone Modification

16.3K
The histone proteins have a flexible N-terminal tail extending out from the nucleosome. These histone tails are often subjected to post-translational modifications such as acetylation, methylation, phosphorylation, and ubiquitination. Particular combinations of these modifications form “histone codes” that influence the chromatin folding and tissue-specific gene expression.
Acetylation
The enzyme histone acetyltransferase adds acetyl group to the histones. Another enzyme, histone...

Spreading of Chromatin Modifications02:25

Spreading of Chromatin Modifications

9.5K
The histone proteins in the nucleosomes are post-translationally modified (PTM) to increase or decrease access to DNA. The commonly observed PTMs are methylation, acetylation, phosphorylation, and ubiquitination of lysine amino acids in the histone H3 tail region. These histone modifications have specific meaning for the cell. Hence, they are called "histone code". The protein complex involved in histone modification is termed as "reader-writer" complex.

Requirements for Human Life01:26

Requirements for Human Life

14.2K
The Earth and its atmosphere have provided humans with air, water, and food, but these are not the only requirements for survival. Humans also require a specific range of temperature and pressure that the Earth and its atmosphere provides.
Oxygen
Atmospheric air is only about 20 percent oxygen, but that oxygen is a key component of the chemical reactions that keep the body alive, including the reactions that produce ATP. Brain cells are susceptible to a lack of oxygen because they require a...

Anatomical Positions01:11

Anatomical Positions

20.7K
In anatomy, several standard anatomical positions are used as references for describing the position and orientation of different body parts. These positions help provide a common frame of reference when discussing anatomical structures. The anatomical position is the standard reference point for describing the body's position and orientation. In this position:
The body is upright, facing forward, and standing erect.
The feet are parallel and flat on the floor.
The arms are hanging by the...

Anatomical Terminology01:20

Anatomical Terminology

27.9K
Knowledge of anatomy is essential to understand human biology and medicine. Anatomists and health care professionals use standard terminology to describe the human body with more precision and no ambiguity. Anatomical terms have mostly Greek and Latin-derived roots. Because these languages are rarely used in conversation, the meaning of words remains the same. Each term is made up of a root in between the prefixes and suffixes. The root of a term often refers to an organ, tissue, or condition,...

Anatomical Movements00:51

Anatomical Movements

16.4K
Anatomical movements refer to the various actions or motions that can be performed by the body's joints and muscles. These movements are described using specific terms to provide a standardized way of discussing and understanding the range of motion at different joints.
Here are some common anatomical movements:
Flexion and extension motions are in the sagittal (anterior–posterior) plane of motion. These movements take place at the shoulder, hip, elbow, knee, wrist,...

Area of Science:

  • Thoracic Surgery
  • Minimally Invasive Surgery
  • Robotic Surgery

Background:

  • Robotic-assisted surgery has evolved, with system upgrades like the transition from the da Vinci Si to the Xi system.
  • Pulmonary lobectomy and segmentectomy are common thoracic procedures increasingly performed with robotic assistance.

Purpose of the Study:

  • To review the technical changes and evaluate the operational efficiency when converting from the Si to the Xi robotic system for pulmonary lobectomy and segmentectomy.
  • To compare operative times, setup, and patient outcomes between the two robotic systems.

Main Methods:

  • Prospective database review of consecutive robotic pulmonary lobectomies and segmentectomies performed by a single surgeon.
  • Comparison of patient demographics, co-morbidities, and pulmonary function between the Si and Xi groups.
  • Analysis of technical differences, docking time, operation duration, skin-to-room exit time, and complication rates.

Main Results:

  • The Xi robot demonstrated significantly shorter median docking time (7.5 vs. 10 min) and operation duration (114 vs. 119 min) compared to the Si robot.
  • No significant differences were observed in median blood loss, transfusion rates, major complication rates, or 30- and 90-day mortality between the Si and Xi groups.
  • Anesthesiologists reported greater comfort with the Xi system due to improved patient head visibility.

Conclusions:

  • The transition from the Si to the Xi robotic system for pulmonary resections involves manageable technical adjustments.
  • The Xi system offers potential improvements in operational efficiency and user comfort without compromising patient safety or outcomes.
  • Further adoption of the Xi system is supported by its demonstrated benefits in this comparative review.
