Integrative Analysis of miRNA and circRNA Expression Profiles and Interaction Network in HSV-1-Infected Primary Corneal Epithelial Cells.

Purpose: Circular RNAs (circRNAs) are products of alternative splicing with roles as competitive endogenous RNAs or microRNA sponges, regulating gene expression and biological processes. However, the involvement of circRNAs in herpes simplex keratitis remains largely unexplored.

Methods: This study examines circRNA and miRNA expression profiles in primary human corneal epithelial cells infected with HSV-1, compared to uninfected controls, using microarray analysis.

Acute effect of a variable pulse width Nd:YAG laser combined with hematoporphyrin monomethyl ether-mediated photodynamic therapy on a cockscomb model of nevus flammeus.

Background: Nevus flammeus (NF) is a congenital vascular malformation.

Objectives: To investigate the acute effect of a variable pulse width Nd:YAG laser combined with hematoporphyrin monomethyl ether (HMME)-mediated photodynamic therapy (PDT) on a cockscomb model of NF.

Material And Methods: Forty-two leghorn roosters were randomly divided into the following 7 groups: group A1 (treated with HMME-mediated PDT; energy density of 75 J/cm2), group A2 (treated with HMME-mediated PDT; 125 J/cm2), group A3 (treated with HMME-mediated PDT; 150 J/cm2), group A4 (treated with HMME-mediated PDT; 175 J/cm2), group B (treated with a variable pulse width Nd:YAG laser), group C (treated with a variable pulse width Nd:YAG laser and HMME-mediated PDT), and group D (the control group).

Premorbid Alterations of Spontaneous Brain Activity in Elderly Patients With Early Post-operative Cognitive Dysfunction: A Pilot Resting-State Functional MRI Study.

Elderly patients with pre-existing cognitive impairment are susceptible to post-operative cognitive dysfunction (POCD). In this study, we investigated whether there is pre-existing local homogeneity and functional connectivity alteration in the brain before surgery for POCD patients as compared to that in non-POCD patients. Eighty elderly patients undergoing major thoracic or abdominal surgeries were recruited.

An improved cellular enucleation method with extracellular matrix and colchicine facilitates the study of nucleocytoplasmic interaction.

Enucleated mammalian cells (cytoplasts) have been widely used for studying differential roles of the cytoplasm and nucleus in various cellular processes. Here, we reported an improved enucleation protocol, in which cells were seeded in extracellular matrix (ECM)-coated 24-wells and spun at 4600 g and 35 °C for 60 min in the presence of cytochalasin B and colchicine. When glass-bottom wells were used, cellular structures and organelles in cytoplasts could be examined directly by confocal microscopy.

The effects of both age and sex on irisin levels in paired plasma and cerebrospinal fluid in healthy humans.

Background: Adipo-myokine irisin has important effects on the metabolism and functioning of multiple tissues and organs. However, the effects of aging and sex on irisin levels in cerebrospinal fluid (CSF) and on circulation have not been comprehensively studied.

Objective: To investigate whether aging and sex can affect irisin levels in both CSF and plasma; to determine whether CSF irisin uptake involves a saturable transport mechanism.

Efficiency of stem cell based therapy in the treatment of diabetic foot ulcer: a meta-analysis.

Diabetic foot ulcer is a chronic, refractory, frequent complication in diabetic patient. Its treatment often requires multidisciplinary joint efforts, diverse strategies have been adopted to address this annoying issue, including stem cell-based therapy/acellular dermal matrix/negative pressure wound therapy etc. However, consensus has not been reached.

Comparison of the impact of prolonged low-pressure and standard-pressure pneumoperitoneum on myocardial injury after robot-assisted surgery in the Trendelenburg position: study protocol for a randomized controlled trial.

Background: Robot-assisted laparoscopic radical prostatectomy and robot-assisted radical cystectomy have gradually become the preferred choices for urologists as they allow surgeons to perform complex procedures more precisely and effectively. The pneumoperitoneum, which is normally applied in these surgeries to provide visual clarity and space to perform the procedure, may cause hemodynamic disturbance, potentially myocardial injury. Thus surgeons have recently considered opting for the low-pressure pneumoperitoneum to lower this negative impact.

Matrigel basement membrane matrix induces eccrine sweat gland cells to reconstitute sweat gland-like structures in nude mice.

Background: Severe burn results in irreversible damage to eccrine sweat glands, for which no effective treatment is available. Interaction between the extracellular matrix and epithelial cells is critical for proper three-dimensional organization and function of the epithelium.

Methods: Matrigel-embedded eccrine sweat gland cells were subcutaneously implanted into the inguinal regions of nude mice.

Localization of Na(+)-K(+)-ATPase α/β, Na(+)-K(+)-2Cl-cotransporter 1 and aquaporin-5 in human eccrine sweat glands.

In order to evaluate the function of the repaired or regenerated eccrine sweat glands, we must first localize the proteins involved in sweat secretion and absorption in normal human eccrine sweat glands. In our studies, the cellular localization of Na(+)-K(+)-ATPase α/β, Na(+)-K(+)-2Cl-cotransporter 1 (NKCC1) and aquaporin-5 (AQP5) in eccrine sweat glands were detected by immunoperoxidase labeling. The results showed that Na(+)-K(+)-ATPase α was immunolocalized in the cell membrane of the basal layer and suprabasal layer cells of the epidermis, the basolateral membrane of the secretory coils, and the cell membrane of the outer cells and the basolateral membrane of the luminal cells of the ducts.

The cellular localization of Na(+)/H(+) exchanger 1, cystic fibrosis transmembrane conductance regulator, potassium channel, epithelial sodium channel γ and vacuolar-type H+-ATPase in human eccrine sweat glands.

The secretory portions of human eccrine sweat glands secrete isotonic fluid into the lumen and then the primary fluid is rendered hypotonic during its passage to the skin surface. During the processes of sweat secretion and absorption, many enzymes and proteins play important roles. In the study, the cellular localizations of Na(+)/H(+) exchanger 1 (NHE1), cystic fibrosis transmembrane conductance regulator (CFTR), potassium channel (KC), epithelial sodium channel γ (γENaC) and vacuolar-type H+-ATPase (V-ATPase) in human eccrine sweat glands and epidermis were detected using immunofluorescence labeling.
