野生动物学报, 2011 精液品质评定的常见方法有精子活力、畸形率和顶体完整率等指标,但这些指标不能评定精子的真实受精能力。目前低渗膨胀试验作为检验精子膜功能的一种方法得到广泛认可,利用它可检验具有完整膜的精子是否具有生化活性。本试验通过对冷冻2只黑猩猩精液进行低渗膨胀来评定冷冻精子的膜完整性。试验结果显示,本研究中的黑猩猩的冷冻精子在低渗溶液中的膨胀率较高,表明试验黑猩猩的冷冻精液有较高的活力,精子具有较高的穿透率和受精能力。

Liothyronine (FK-300) in the Treatment of Male Infertility [PDF]
, 1961 1) L-Triiodothyronine (FK-300) was given to 12 patients of male infertility, 3 of azoospermia and 9 of oligospermia. There was an increase in sperm count observed in 8, a rise in sperm motility in 7, and the wife of the highly oligospermic men conceived.

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT High‐entropy alloys (HEAs) have attracted considerable interest from researchers owing to their tunable chemical compositions, exceptional structural stability, and promising catalytic properties. However, their large‐scale application is often hindered by complex manufacturing techniques and poor durability.

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Periodontitis is a chronic infectious oral disease triggered by periodontopathogenic bacteria, resulting in the progressive inflammation and destruction of the tissues surrounding teeth. To achieve reprogramming of the infectious microenvironment for periodontitis therapy, a nanoformulation was proposed by loading polydopamine (PDA) with ...

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT The development of efficient and stable bifunctional catalysts remains a key challenge for green hydrogen production via electrochemical water splitting. In this study, a bimetallic Mo/Fe‐doped CoP2 nanoleaf array anchored on carbon cloth (Mo, Fe‐CoP2@CC) was synthesized from zeolitic imidazolate framework‐L (ZIF‐L) via an ion‐exchange and low‐

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Precise control of chemical ordering in bimetallic nanocatalysts offers a route to decouple activity and selectivity in acetylene hydrogenation, but direct atomic‐scale evidence linking surface order to catalytic performance is scarce. Here, we tune Pd‐Cu nanoalloys from chemically disordered to highly ordered states by composition control and
