2022年3月3日 · The Harris-Galante (HG) prosthesis is a first-generation, cementless total hip arthroplasty (THA) prosthesis. Considering the recent increase in the demand for THA in young patients and their life expectancy, a study with a follow-up duration of longer than 20 years in a young population is needed.

2023年2月28日 · In this study, Liu et al. show that D2HGDH deficiency leads to aberrant accumulation of D-2-HG and impaired NSC activation. Accumulated D-2-HG directly binds to ACLY and competitively inhibits its enzymatic activity, thereby reducing acetyl-CoA production and diminishing histone acetylation.

The HG is a group of P-cadherin-positive epidermal cells extended from and located below the bulge; it is morphologically similar to the embryonic hair germ, hence the name. The bulge constitutes the quiescent niche and possesses DNA label-retaining stem cells. The HG receives dermal papilla signals first and becomes activated at the end of ...

2023年2月28日 · Here, we find that loss of mitochondrial D-2-hydroxyglutarate dehydrogenase (D2HGDH) leads to aberrant accumulation of D-2-hydroxyglutarate (D-2-HG) and impaired RGL activation. Mechanistically, accumulated D-2-HG bonds directly to ATP-citrate lyase and competitively inhibits its enzymatic activity, thereby reducing acetyl-CoA production and ...

2009年2月6日 · During rest (telogen), the hair germ (HG) appears as a small cell cluster between the slow-cycling bulge and dermal papilla (DP). Here we show that HG cells are derived from bulge stem cells (SCs) but become responsive quicker to DP-promoting signals. In vitro, HG cells also proliferate sooner but display shorter-lived potential than bulge cells.

2016年6月26日 · The easiest way to identify older Zimmer total hip prostheses is by the locking tabs on the HG shells. The easiest way to determine HG vs. HGII shells is that the HG used 4.5 mm screws and the HGII used 6.5 mm. Zimmer Biomet still makes liners for the HGII shells.

The HG (Harris/Galante Porous Hip Prosthe-ses) stem was a straight titanium alloy (Titanium Ti-6Al-4V) stem with a collar and non-circumfer-ential proximal fiber-mesh pads made of pure tita-nium. The acetabular component was a modular, hemispherical press-fit cup with a sintered titanium fiber-mesh at the bone-implant interface and holes
