#1
REVIEW
Arnon Lavi, Michael Cohen
Prostate cancer (Pca) is the most common malignancy in men and the second cause of death from cancer. The prostate specific antigen (PSA) assay has been used for Pca screening since the beginning of the 1990's and has brought a 40% reduction in mortality. Since Pca is a diverse disease, early detection can lead to overdetection and overtreatment. Pca treatment has significant adverse effects, namely incontinence and erectile dysfunction. How is it then that a simple and inexpensive test that probably caused the most significant reduction in mortality from cancer ever, is regarded to be "not recommended" by some health organizations? Why did the use of PSA testing fall drastically in the US in the last couple of years, while, at the same time, the tendency for diagnosis of higher risk diseases is noticed through large controlled studies, showing the efficacy of PSA testing in mortality reduction? Will PSA serve as a milestone for early detection and mass population screening in general? This review will deal with aspects of PSA screening and will bring the latest updates and dilemmas concerning this evolving topic...

Horizontal canal benign paroxysmal positional vertigo (HCBPPV) is one form of benign paroxysmal positional vertigo. HC-BPPV is characterized by intermittent recurrent episodes of vertigo following a change in head position relative to gravity. HC-BPPV prevalence ranges from 5%-33% of all dizziness cases seen in otolaryngology, neurology and family physician clinics. Various factors, such as ear and head injury, can cause HC-BPPV. Cardiovascular disease and iatrogenic reasons are also implicated. Despite the prevalence of the disease, there are various forms of diagnostic procedures, some of which are unfamiliar to the therapist and some are controversial...

In this study, a new agar-degrading strain was isolated from soil with agar as a sole carbon source and energy. Based on its morphological, physiological, biochemical characterization and 16S rDNA sequence, the strain was identified as Streptomyces lavendulae UN-8. The extracellular agarase activity reached 0.03 U/ml after fermentation in shake flask (250 ml), which was close to other reported non-marine microorganisms. Furthermore, it is interesting that the growth of UN-8 would be inhibited by glucose (40 g/L) and maltose (40 g/L) with the inhibitory rate of 100% and 70%, respectively...

BACKGROUND: Peritoneal injury is an important cause of technical failure of long-term peritoneal dialysis (PD). Encapsulating peritoneal sclerosis (EPS) is a severe complication of long-term PD with potentially life threatening consequences. CD147 is a glycoprotein with diverse functions including modulation of extracellular matrix via induction of matrix metalloproteinases, cell adhesion, and regulation of immune reactions. We hypothesized that CD 147 plays a role in the peritoneal cavity...

Mitochondria are the prime source of ATP in cardiomyocytes. Impairment of mitochondrial metabolism results in damage to existing proteins and DNA. Such deleterious effects are part and parcel of the aging process, reducing the ability of cardiomyocytes to counter stress, such as myocardial infarction and consequent reperfusion. In such conditions, mitochondria in the heart of aged individuals exhibit decreased oxidative phosphorylation, decreased ATP production, and increased net reactive oxygen species production; all of these effects are independent of the decrease in number of mitochondria that occurs in these situations...

Accumulating lines of evidence suggest that reactive oxygen species (ROS) may act as intracellular signaling molecules under cellular stress conditions, activating several molecular pathways. Autophagy, the intracellular mechanism by which cells digest and recycle unfolded proteins and dysfunctional organelles, is emerging as a major target of ROS and NADPH oxidase (Nox) enzymes, the major generators of ROS. While autophagy represents an important self-defense mechanism in promoting cell survival, it may be maladaptive in some conditions...

The principle of respect for autonomy requires informing patients adequately and appropriately about diagnoses, treatments, and prognoses. However, some clinical cases may cause ethical dilemmas regarding telling the truth. Under the existence especially of certain cultural, social, and religious circumstances, disclosing all the relevant information to all pertinent parties might create harmful effects. Even though the virtue of telling the truth is unquestionable, sometimes de facto conditions compel physicians to act paternalistically to protect the patient/patients from imminent dangers...

Lynch syndrome (LS) is a genetic condition conferring an elevated risk of gastrointestinal, gynecologic and other malignancies, often before the age of 50. Current guidelines recommend prophylactic gynecologic surgery to manage inherited cancers for female mutation carriers. Data is lacking on women's quality of life following surgery. In this pilot study, we explored how women described their quality of life post-prophylactic gynecologic surgery and the factors that affected post-surgery experiences. A qualitative interview study was the chosen design...

PURPOSE: Osteosarcoma is one of the most common malignancies in bones and is often found in limbs. Until now, it is not clear why osteosarcoma is rare in the spine. On the other hand, previous biological characteristics study about osteosarcoma of spine was also rare because of its low incidence. To explore the biology of spinal osteosarcoma, a stable osteosarcoma cell line derived from spine is necessary. METHODS: A novel osteosarcoma cell line named NEO217 was established from spinal osteosarcoma tissues obtained from a Chinese male patient...

Rong Zhang, Xin-Jie Xu, Hong-Feng Zhang, Song-Ping Han, Ji-Sheng Han
The nonapeptides oxytocin (OXT) and arginine vasopressin (AVP) are two key mediators in regulating various aspects of mammalian social behaviours. There are several lines of evidence that genetic variants of the OXT/AVP system exist in autism spectrum disorder (ASD) and that this system is dysfunctional at least in some ASD entities. These findings have stimulated the interest to perform studies testing the potential therapeutic application of OXT/AVP in ASD. In this respect animal models are critical for investigating the pathophysiology and for compound screening leading to new therapeutic approaches...

Pediatric alopecia areata is a spectrum of autoimmune non-scarring alopecia in which some patients lose small patches of hair from their scalp but others lose more or all of the hair from the scalp and body, including eyebrows and eyelashes. Few studies have looked at therapies for this disorder in children, so much of the data are derived from adult literature and describe off-label use of medication. Generally, topical therapies consisting of topical steroids and topical irritating compounds/contact sensitizers are used...
