Catalase is potentially useful to catalyze the conversion of endogenous HO to O for hypoxia reversion. However, the efficient delivery of catalase into the hypoxia regions of tumors is a huge challenge.

However, current medications are ineffective against decreased sensation on the ocular surface. While electroacupuncture (EA) effectively alleviates decreased sensation on ocular surface of DE in patients with T2DM, the neuroprotective mechanism remains unclear.

The neuroprotective effect of andrographolide (AGA) has been confirmed, anda acetylated derivative of AGA (3,14,19-triacetylandrographolide, ADA) was considered to have stronger efficacy.
Purpose: The current study aims to investigate the impact of ADA on cognitive ability in a sporadic AD model and explore its potential mechanism.
Purpose: This study aimed to examine electroacupuncture's influence on ocular pain and its potential modulation of the TNF-ɑ mediated ERK1/2/P2XR signaling pathway in dry eye-induced rat models.
Methods: Male Sprague-Dawley rats with induced dry eye, achieved through extraorbital lacrimal gland removal, were treated with electroacupuncture. Comprehensive metrics such as the corneal mechanical perception threshold, palpebral fissure height, eyeblink frequency, eye wiping duration, behavioral changes in the open field test, and the forced swimming test were employed.
Recombinant human growth hormone (rhGH) is clinically used to treat growth hormone deficiency (GHD). However, daily administration of rhGH is required due to its poor stability and short blood circulation, which causes pains and burdens as well as inconvenience to patients. In this study, a method for genetically fusing rhGH to a thermosensitive polymer of elastin-like polypeptide (ELP) is reported, using which the rhGH-ELP thermosensitive fusion protein can be purified by the thermosensitivity of ELP instead of chromatography.

The original radial-spoke lens array has dense radial sampling and coarse azimuthal sampling. The sparsity and inhomogeneity of spatial frequency sampling lead to the loss of spatial frequency information and blurred reconstructed images.

Objectives: To compare the clinical efficacy and safety of acupuncture and sodium hyaluronate eye drop in the treatment of aqueous deficiency dry eye.
Methods: A total of 60 patients (120 eyes) with aqueous deficiency dry eye were randomly divided into an observation group (30 cases, 1 case dropped out) and a control group (30 cases, 1 case dropped out). In the control group, sodium hyaluronate eye drop were used, one drop at a time, 4 times a day, for 14 consecutive days.

Unfortunately, the intrinsic shortcomings of ASP, namely high immunogenicity, severe toxicity, short half-life, and poor stability, restrict its clinical usage. Poly(ethylene glycol) conjugation (PEGylation) of ASP is an effective strategy to address these issues, but it is not ideal in clinical applications due to complex chemical synthesis procedures, reduced ASP activity after conjugation, and pre-existing anti-PEG antibodies in humans.
