Article Synopsis
  • A new ultrasound-guided protocol for stellate ganglion block in rats significantly improves accuracy and reduces complications compared to traditional blind techniques.
  • The study involved 56 rats divided into two groups, with one group receiving the block using ultrasound and the other using a blind injection method, and it measured outcomes like effective volume and complication rates.
  • Results showed that the ultrasound-guided method required less lidocaine (0.040 ml) compared to the blind method (0.639 ml) and had a much lower incidence of complications, particularly regarding the brachial plexus and vagus nerve.

The abundance of insects in Burmese amber illustrates a highly diverse orthoptera community of the mid-Cretaceous, but the records of ripipterygids are relatively rare. Here, we reviewed the genus of (Xu, Fang and Jarzembowski, 2020) and transfered it from Tridactylidae to Ripipterygidae. Based on four ambers specimens collected from northern Myanmar, two new species, sp.

Background: Sleep deprivation (SD)-induced cognitive impairment is highly prevalent worldwide and has attracted widespread attention. The temporal and spatial oscillations of circadian genes are severely disturbed after SD, leading to a progressive loss of their physiological rhythms, which in turn affects memory function. However, there is a lack of research on the role of circadian genes and memory function after SD.

Background: Renal ischemia-reperfusion injury (IRI) is a disease with high incidence rate in kidney related surgery. Micro RNA (miRNA) and transcription factors (TFs) are widely involved in the process of renal IRI through regulation of their target genes. However, the regulatory relationships and functional roles of TFs, miRNAs and mRNAs in the progression of renal IRI are insufficiently understood.

Background: Sleep deprivation (SD) often leads to complex detrimental consequences, though the mechanisms underlying these dysfunctional effects remain largely unknown. We investigated whether the right stellate ganglion block in rats can improve the spatial learning and memory dysfunction induced by sleep deprivation by alleviating the damage of hippocampus in rats.

Methods: Sixty four male Sprague Dawley rats were randomly divided into four groups: Control, SD (sleep deprivation), SGB (stellate ganglion block) and SGB + SD (stellate ganglion block+ sleep deprivation) (n = 16).

Purpose: To characterize and compare patient-reported recovery of function after cataract or glaucoma surgery using a novel visual analog scale.

Design: Prospective observational cohort study.

Methods: Daily for 2 weeks and weekly thereafter, patients recovering from trabeculectomy, tube shunt implantation, or cataract extraction (CE) completed a diary-style questionnaire including visual analog scales (VASs; scored 0-100) grading pain and global function.

Purpose: To compare early postoperative intraocular pressure (IOP) in patients who underwent cataract surgery alone with those who underwent cataract surgery combined with implantation of a Hydrus Microstent (HMS) (Ivantis, Irvine, CA).

Design: Subanalysis of data from the randomized controlled HORIZON trial, a multicenter trial including 26 US and 12 international sites.

Participants: Participants with mild/moderate primary open-angle glaucoma (POAG) and visually significant cataract with mean modified diurnal IOP between 22 and 34 mmHg after washout of IOP-lowering medications.

Purpose Of Review: The use of computers has become increasingly relevant to medical decision-making, and artificial intelligence methods have recently demonstrated significant advances in medicine. We therefore provide an overview of current artificial intelligence methods and their applications, to help the practicing ophthalmologist understand their potential impact on glaucoma care.

Recent Findings: Techniques used in artificial intelligence can successfully analyze and categorize data from visual fields, optic nerve structure [e.

Purpose: Glaucoma is a well-documented complication of corneal transplants, contributing significantly to ultimate visual loss. Reported incidence of glaucoma following corneal transplants is highly variable, and definitions of posttransplant glaucoma are inconsistent. Here we use glaucoma surgery as a more rigid and specific endpoint to compare rates following different corneal transplant surgeries.

Purpose: To compare variables and outcomes from ocular trauma leading to either enucleation or evisceration to better inform surgical decision making.

Design: Retrospective chart review.

Methods: We reviewed 441 patients between 2001 and 2012 presenting with ocular trauma to a Level 1 trauma center in Queens, New York; of these, there were 16 enucleations and 6 eviscerations.

The effective induction of p21(WAF1/CIP1/Cdkn1a) (p21) expression in p53-negative cancer cells is an important avenue in cancer management. We investigated the ability of various common chemotherapeutic drugs to induce p21 expression in p53-negative cancer cells and showed that the induction of p21 expression by oxaliplatin is caused by the derepression of a previously unrecognized negative regulatory element with a Sp1/Sp3 palindrome sequence core at -216 to -236 of the p21 proximal promoter. Electrophoretic mobility shift and antibody super-shift assays confirmed the specific binding of Sp1/Sp3, and showed that the oxaliplatin-mediated derepression of p21 transcription was associated with an increased Sp1/Sp3 phosphorylation and binding affinity to the oxaliplatin-responsive element.

Objective: To investigate a simple, safe, and effective surgical approach to treat vascular malformations (VM).

Methods: Tissues of vein, heart, liver, and kidney were obtained and pathologically observed from 30 rabbits whose central veins of the ears were retained with copper needles, and the concentration of Cu in serum was measured. In the clinical research, 3 methods were employed to treat 89 patients with VM: (1) retaining copper needles alone; (2) ligaturing lesions and retaining copper needles; (3) retaining copper needles charged with direct current (DC).

Recently, a double-anchoring theory (DAT) of lightness perception was proposed (P. Bressan, 2006), which offers explanations for all the data explained by the original anchoring theory (A. Gilchrist et al.

Objective: To explore the changes in the serum Cu2+ and the indexes for the liver pathology and biochemistry before and after the copper needle retained in the central veins of the rabbit ears.

Methods: Forty-nine New Zealand rabbits were randomly divided into 5 groups: Group A (copper needles retained for 1 d), Group B (3 d), Group C (5 d), Group D (7 d), and Group E (the control group, without any copper needles retained). In each experimental group, there were 10 rabbits, and in the control group there were 9 rabbits.
