CONTEXT: Lymphedema consists of extracellular fluid retention caused by lymphatic obstruction. In chronic forms, fat and fibrous tissue accumulation is observed. Genital lymphedema is a rare condition in developed countries and may have primary or acquired etiology. It generally leads to urinary, sexual and social impairment. Clinical treatment usually has low effectiveness, and surgical resection is frequently indicated. CASE REPORT: We report a case of a male-to-female transgender patient who was referred for treatment of chronic genital lymphedema...

BACKGROUND The abdominal straining pattern can act as a novel parameter for improving the prediction of bladder outlet obstruction (BOO). To preserve detrusor function in the early stage of urinary system impairment, such as BOO, we establish a novel method for cystometry and Intra-abdominal pressure (IAP) assessments in rodents without cystostomy. MATERIAL AND METHODS Twenty mice and rats were divided into three groups (control, sham-operated and BOO group) respectively. The cystometry and IAP assessments were measured by the pediatric venous indwelling sheath and coronary dilatation catheter connected to Laborie urodynamic system on postoperative day 7...

With the novel possibilities for detecting molecules of interest with extreme sensitivity also comes the risk of encountering hitherto negligible sources of error. In life science, such sources of error might be the broad variety of additives such as dithiothreitol (DTT) used to preserve enzyme stability during in vitro reactions. Using two different assays that can sense strand interruptions in double stranded DNA, we here show that DTT is able to introduce nicks in the DNA backbone. DTT was furthermore shown to facilitate the immobilization of fluorescent DNA on an NHS-ester functionalized glass surface...

BACKGROUND: Patients who suffer a cardiac arrest from trauma rarely survive, even with aggressive resuscitation attempts, including an Emergency Department (ED) thoracotomy. Emergency Preservation and Resuscitation (EPR) was developed to utilize hypothermia to buy time to obtain hemostasis before irreversible organ damage occurs. Large animal studies have demonstrated that cooling to tympanic membrane temperature 10°C during exsanguination cardiac arrest can allow up to 2 hours of circulatory arrest and repair of simulated injuries with normal neurologic recovery...

BACKGROUND: Nipple-sparing mastectomy permits complete preservation of the nipple-areola complex with excellent aesthetic results and with oncologic safety similar to that associated with traditional mastectomy techniques. However, outcomes have not been directly compared for tissue expander-, immediate implant-, and autologous tissue-based breast reconstruction after nipple-sparing mastectomy. METHODS: All patients undergoing nipple-sparing mastectomy from 2006 to June of 2016 were identified at a single institution...

BACKGROUND: Ensuring donor wellbeing warrants ongoing monitoring following living kidney donation. However, there is considerable variability in donor follow up processes, including information provided to donors regarding self-care. Loss to follow up is common, suggesting that the aims and benefits of monitoring and follow up may not be apparent. We aimed to describe the experiences and expectations of living kidney donors regarding follow up and self-care after donation. METHODS: Participants from 3 transplant centers in Australia and Canada participated in 14 focus groups (n=123)...

RATIONALE: Death following orthopedic surgery has become rare, but does occur. Acute myocardial infarction (AMI) can be a cause of such death, but diagnosis of AMI is often challenging, even by autopsy. PATIENT CONCERNS: We have recently experienced 2 cases of sudden death after bone fracture surgery, in which AMI and pulmonary thromboembolism were clinically suspected as causes of death. Case 1 was a 60-year-old male with a history of diabetes mellitus who died 7 days after surgery for Lisfranc dislocation fracture...

BACKGROUND: Reduced information-processing speed (IPS) is a primary cognitive deficit of multiple sclerosis (MS) patients. The neural efficiency hypothesis describes an inverse relationship between cognitive performance in a task and the amount of cognitive resources devoted to it. Previous studies have shown that the neural efficiency hypothesis provides an appropriate framework to explore cognitive dysfunction in neurological patients. OBJECTIVE: The aim of this study was to explore the neural efficiency hypothesis regarding IPS capabilities in cognitively preserved MS patients...

The achievement of animal cloning and subsequent development of cell reprogramming technology are having a profound impact on our view of the mechanisms of aging in complex organisms. The experimental evidence showing that an adult somatic nucleus implanted into an enucleated oocyte can give rise to a whole new individual strongly suggests that the integrity of the genome of an adult nucleus is fully preserved. Here, we will review recent experimental evidence showing that pluripotency gene-based cell reprogramming can erase the epigenetic marks of aging and rejuvenate cells from old individuals reversing most signs of aging and that when induced pluripotent stem cells are differentiated back to the cell type of origin, the rejuvenated cells share many of the features of wild-type counterparts from young donors...

The molecular mechanism of endoplasmic reticulum (ER) stress in vascular pathophysiology remains inadequately understood. We studied the role of ER stress in homocysteine-induced impairment of coronary dilator function, with uncovering the molecular basis of the effect of ER stress on smooth muscle large-conductance Ca2+-activated K+ (BKCa) channels. The vasodilatory function of BKCa channels was studied in a myograph using endothelium-denuded porcine small coronary arteries. Primary cultured porcine coronary artery smooth muscle cells were used for mRNA and protein measurements and current recording of BKCa channels...

BACKGROUND/AIMS: Transforming growth factor-β1 (TGF-β1) plays important roles in penile corporal fibrosis and veno-occlusive dysfunction (CVOD). Angiotensin II (Ang II) is critically involved in erectile dysfunction, and blocking of Ang II is more important than inhibition of TGF-β in non-penile tissue fibrosis. However, the role of Ang II in corporal fbrosis and CVOD in a diabetic condition has not been investigated. METHODS: Diabetic rats were treated with sildenafil or losartan (an Ang II antagonist) alone or in combination...
