まとめ
慢性腰痛 (LBP) は,小腹筋 (psoas major) と直腸腹筋 (rectus abdominis) の筋肉が小さくなること,体幹と股関節の屈曲器が弱くなることに関連している. 筋肉のサイズと強さの不均衡はLBPを悪化させる可能性があります. ターゲットを絞ったリハビリテーションが鍵です.
科学分野:
- 筋肉・骨格の健康について
- バイオメディカルエンジニアリング

- 慢性LBP患者と対照群の筋肉横断面 (CSA) と強さを比較する.
- LBPにおける筋肉形態と強さの欠損の関係を調査する.
- LBPのリハビリテーションのための潜在的なターゲットを特定する.
主な方法:
- 50人の慢性腰痛患者と30人の健康な対照群を募集した.
- ランボサクラMRIは,パラvertebral,腹部,およびヒップの筋肉のCSAを測定しました.
- イソキネティック・ダイナモメトリーは,トランクとヒップ・フレクサー/エクステンサーの強さを評価した.
主要な成果:
- LBPの患者は,対照群と比較して,より小さなpsoas majorと直腸腹部CSAを持っていた.
- トランク・フレクサーとエクステンサーの強さはLBP患者で低下し,強さの比率は低下しました.
- ヒップフレクサー/エクステンサーの不均衡への傾向は,LBP患者で観察されました.
結論:
- 慢性的なLBPは,psoas majorと直腸腹筋の縮と関連しています.

02:29Relative Strengths of Conjugate Acid-Base Pairs
52.8K
Brønsted-Lowry acid-base chemistry is the transfer of protons; thus, logic suggests a relation between the relative strengths of conjugate acid-base pairs. The strength of an acid or base is quantified in its ionization constant, Ka or Kb, which represents the extent of the acid or base ionization reaction. For the conjugate acid-base pair HA / A−, the ionization equilibrium equations and ionization constant expressions are

02:35Acid and Bases: Ka, pKa, and Relative Strengths
34.7K
This lesson delves into a critical aspect of the relative strengths of acids and bases. The strength of an acid is evaluated by the acid dissociation into its conjugate base and a hydronium ion in water. The complete dissociation of a strong acid is confirmed with a very high concentration of hydronium ions. As a result, an incomplete dissociation process affirms a weak acid. Therefore, the equilibrium is in the forward direction for strong acids and backward for weak acids in these reactions.

03:02Acid/Base Strengths and Dissociation Constants

The relative strength of an acid or base is the extent to which it ionizes when dissolved in water. If the ionization reaction is essentially complete, the acid or base is termed strong; if relatively little ionization occurs, the acid or base is weak. There are many more weak acids and bases than strong ones. The most common strong acids and bases are listed below:

Binary Acids and Bases
In the absence of any leveling effect, the acid strength of binary compounds of hydrogen with nonmetals (A) increases as the H-A bond strength decreases down a group in the periodic table. For group 17, the order of increasing acidity is HF < HCl < HBr < HI. Likewise, for group 16, the order of increasing acid strength is H2O < H2S < H2Se < H2Te. Across a row in the periodic table, the acid strength of binary hydrogen compounds increases with increasing...

Strength tests for cement are not performed directly on neat cement paste due to difficulty in obtaining consistent, reliable specimens. Instead, cement is typically tested in the form of cement-sand mortar.
For compressive strength tests, ASTM C 109-05 standards prescribe a cement-sand mix ratio of 1:2.75 and a water/cement ratio of 0.485 for making 2-inch cubes. These cubes are mixed, cast, and cured in saturated lime water at 23°C until testing. Flexural strength testing, outlined in...

01:30Relation Between Tensile Strength and Compressive Strength of Concrete

Concrete is a fundamental building material, and understanding its strengths is crucial for construction projects. The relationship between its tensile and compressive strengths is intricate, showing that while these strengths are related, they do not increase at the same rate. Tensile strength's growth is slower and is affected by various factors such as the methods used for testing, the size and shape of the specimen, the texture of the aggregate used, and the moisture content of the...
