CT-based radiomics prediction of complete response after stereotactic body radiation therapy for patients with lung metastases.

Purpose: Stereotactic body radiotherapy (SBRT) is a key treatment modality for lung cancer patients. This study aims to develop a machine learning-based prediction model of complete response for lung oligometastatic cancer patients undergoing SBRT.

Materials And Methods: CT images of 80 pulmonary oligometastases from 56 patients treated with SBRT were analyzed.

Evidence for apical-basal transition in the delay of the reflection components of otoacoustic emissions.

Stimulus-frequency, transient-evoked, and distortion product otoacoustic emissions (OAEs) have been measured in eight normal-hearing human ears over a wide stimulus level range, with high spectral resolution. The single-reflection component of the response was isolated using time-frequency filtering, and its average delay was measured as a function of frequency and stimulus level. The apical-basal transition was studied by fitting the average delay of the filtered single-reflection OAEs, expressed in number of cycles, to a three-slope power-law function with two knot frequencies.

Adiponectin expression in human epicardial adipose tissue in vivo is lower in patients with coronary artery disease.

Background: Intra-peritoneal adipose tissue is recognized as a predictor of metabolic syndrome and may contribute to the risk for cardiovascular disease by the production of adipocytokines, including adiponectin. Nevertheless, there is no knowledge on whether other visceral depots of adipose tissue, including the epicardial fat, have any metabolically active role, including production of adiponectin.

Aim Of The Study: We sought to evaluate adiponectin protein expression in epicardial adipose tissue in vivo both in patients with severe coronary artery disease (CAD) and in subjects without CAD.

Detection of deleted mitochondrial DNA in Kearns-Sayre syndrome using laser capture microdissection.

A novel 4949-base pair mitochondrial DNA (mtDNA) deletion was detected in various tissues in a postmortem study of a patient with Kearns-Sayre syndrome (KSS). Deleted mtDNA levels were higher in skeletal muscle and brain and lower in kidney, working myocardium, and endocrine tissues (thyroid, parathyroids, pancreas, and adrenal glands). The distribution of the deletion in skeletal muscle and conducting myocardium was analyzed by means of laser capture microdissection (LCM).

Functional anatomy of the human vagina.

Anatomy studies normally precede physiology. While the anatomy of the penis and the biochemical and molecular regulation of erection are largely known, the exact anatomical description of the human clitoris was produced in 1998, the taxonomy of female sexual dysfunctions classified in 1999, and biochemistry of female excitation described only in 2002. There are various reasons for this.
