#1
Ju Hwan Cho, Joong-Soo Han
The role of Phospholipase D (PLD) in cancer development and management has been a major area of interest for researchers. The purpose of this mini-review is to explore PLD and its distinct role during chemotherapy including anti-apoptotic function. PLD is an enzyme that belongs to the phospholipase super family and is found in a broad range of organisms such as viruses, yeast, bacteria, animals, and plants. The function and activity of PLD are widely dependent on and regulated by neurotransmitters, hormones, small monomeric GTPases, and lipids...

Background: To examine the proportion of Canadian adults with a history of child abuse who disclosed the abuse to child protection services before age 16 years and identify the effect of social support and disclosure of child abuse on lifetime suicidal ideation. Methods: Data for this study came from the Statistics Canada 2012 Canadian Community Health Survey-Mental Health (N = 9,076). Binary logistic regression was conducted to identify the effect of social support and disclosure of child abuse on suicidal ideation while simultaneously adjusting for the effect of type of child abuse and demographic, socioeconomic, health, and mental health factors...

Microcirculation impairment and related vasculopathy is a hallmark of systemic sclerosis. Digital ulcers are second only to Raynaud's phenomenon as a vascular complication occurring in scleroderma patients. Digital ulcers are painful and generate disability. Furthermore, patients may develop recurrent digital ulcers and one may ask whether the outcomes of such patients might be different to those of unaffected ones. Recently several registries have provided relevant information about digital ulcers. Male sex and severe skin disease seem to be the main associated factors observed in several registries...

Long-term testosterone replacement therapy is mainly monitored by trough levels of serum testosterone (S-T), while urinary testosterone (U-T) is used by forensic toxicology to evaluate testosterone doping. Testosterone in saliva (Sal-T) may provide additional information and simplify the sample collection. We aimed to investigate the relationships between testosterone measured in saliva, serum and urine during standard treatment with 1,000 mg testosterone undecanoate (TU) every 12th week during 1 year. This was an observational study...

REVIEW
Arne Ohlsson, Sanjay M Aher
BACKGROUND: Preterm infants have low plasma levels of erythropoietin (EPO), providing a rationale for the use of erythropoiesis-stimulating agents (ESAs) to prevent or treat anaemia and to provide neuro protection and protection against necrotising enterocolitis (NEC). Darbepoetin (Darbe) and EPO are currently available ESAs. OBJECTIVES: To assess the effectiveness and safety of ESAs (erythropoietin (EPO) and/or Darbe) initiated early (before eight days after birth) compared with placebo or no intervention in reducing red blood cell (RBC) transfusions, adverse neurological outcomes, and feeding intolerance including necrotising enterocolitis (NEC) in preterm and/or low birth weight infants...

Claudia Helga Le Guin, Klaus Metz, Norbert Bornfeld
Primary intraocular lymphomas are rare tumours that can be further subdivided into primary vitreoretinal and the even rarer primary uveal lymphoma. The incidence of primary vitreoretinal lymphoma (PVRL) has increased during the last few decades. Differential diagnostic distinction between lymphoma and posterior uveitis is often difficult, so that adequate diagnosis and treatment is often delayed. This is fatal, because PVRL is often associated with primary central nervous lymphoma. To confirm the diagnosis, prior treatment of cytological or histological detection of lymphoma cells is the gold standard...

Optical coherence tomography (OCT) enables noninvasive high-resolution 3D imaging of the human retina, and thus plays a fundamental role in ophthalmology. Via OCT examination, even subtle retinal changes can be captured, which occur in very early stages of different diseases (e.g., glaucoma, diabetes mellitus, or age-related macular degeneration). Yet, analyzing the resulting data is challenging. Conventionally, OCT data are strongly aggregated via automated methods. While this reduces the amount of information to be analyzed, it also makes it difficult, if not impossible, to identify small and localized retinal changes...

Measles are one of the most contagious diseases of mankind. Measles incidence has declined worldwide since the introduction of vaccinations. Due to low numbers of measles cases in countries with high vaccination rates the population is not aware of possible complications of measles any more. Measles elimination is an important goal set by all regions of the World Health Organization. However, it remains a challenge for Germany and other European countries. Because of a high proportion of susceptibles in specific population and age groups outbreaks take place in Germany every year after importation of the virus...

Quantitative proteomics of postmortem human brain can identify dysfunctional proteins that contribute to neurodegenerative disorders like Alzheimer disease (AD) and frontotemporal dementia. Similar studies in chronic traumatic encephalopathy (CTE) are limited, therefore we hypothesized that proteomic sequencing of CTE frontal cortex brain homogenates from varying CTE pathologic stages may provide important new insights into this disorder. Quantitative proteomics of control, CTE and AD brains was performed to characterize differentially expressed proteins, and we identified over 4000 proteins in CTE brains, including significant enrichment of the microtubule associated protein tau...

Pre-conceptional paternal exposures may affect offspring's health, which cannot be explained by mutations in germ cells, but by persistent changes in the regulation of gene expression. Therefore, we investigated whether pre-conceptional paternal exposure to benzo[a]pyrene (B[a]P) could alter the offspring's phenotype. Male C57BL/6 mice were exposed to B[a]P by gavage for 6 weeks, 3x per week, and were crossed with unexposed BALB-c females 6 weeks after the final exposure. The offspring was kept under normal feeding conditions and was sacrificed at 3 weeks of age...

Yigal Horowitz, Leonid Oster, Ilan Eliyahu
The literature describing the experimental investigations of possible dose-rate effects in the thermoluminescence (TL) of LiF:Mg,Ti (Harshaw) is reviewed. The total lack of glow curve analysis, coupled with inclusion of all or part of the high temperature TL and absence of parallel measurements of possible dose-rate effects in the irradiation stage severely limit the scientific and technical level of the experiments. In addition, the experimental procedures are far from sufficient to warrant any conclusion concerning the presence or absence of dose-rate effects in the TL of LiF:Mg,Ti...

Aims: DSM-5 has added craving as a new criterion and changed the diagnostic structure of alcohol use disorder (AUD). Though craving has long been a target of intervention, less is known about the impact this addition will have on prevalence and factor structure of AUD, particularly in non-treatment seeker with alcohol problems. Methods: Non-treatment seeking individuals reporting alcohol-related problems (N = 296) completed a structured clinical interview and the Penn Alcohol Craving Scale (PACS)...

Background: Campylobacter species are a leading cause of diarrheal disease globally with significant morbidity. Primary prevention efforts have yielded limited results. Rifaximin chemoprophylaxis decreases travelers' diarrhea rates and may be suitable for high risk persons. We assessed the efficacy of rifaximin in the controlled human infection model (CHIM) for Campylobacter jejuni. Methods: Twenty-eight subjects were admitted to an inpatient facility and randomized to a twice daily dose of 550 mg rifaximin or placebo...

KLK8 (also called neuropsin) is a serine protease that plays distinct roles in the skin and hippocampus. In the skin, KLK8 influences keratinocyte proliferation and desquamation, and activates antimicrobial peptides in sweat. In the hippocampus, KLK8 affects memory acquisition. Here, we examined the evolution of KLK8 in mammals and discovered that, out of 70 placental mammals, KLK8 is exclusively lost in three independent fully-aquatic lineages, comprising dolphin, killer whale, minke whale and manatee. In addition, while the sperm whale has an intact KLK8 reading frame, the gene evolves neutrally in this species...

Background: Interactions between principal cytotoxic thiopurine metabolites, 6-thioguanine nucleotides (6-TGN), and infliximab (IFX) and anti-IFX antibodies (Abs) may contribute to higher effectiveness of IFX-thiopurine-combination therapy than monotherapies in inflammatory bowel disease. Methods: To examine if thiopurine metabolites influenced trough IFX and anti-IFX Abs, 89 patients previously assessed for anti-IFX Abs were included. To assess if IFX influenced thiopurine metabolites, 8 patients having responded to 12 weeks of intensified IFX at a constant thiopurine dosing were included...

Plant salt tolerance can be improved by grafting onto salt-tolerant rootstocks. However, the underlying signaling mechanisms behind this phenomenon remain largely unknown. To address this issue, we used a range of physiological and molecular techniques to study responses of self-grafted and pumpkin-grafted cucumber plants exposed to 75 mM NaCl stress. Pumpkin grafting significantly increased the salt tolerance of cucumber plants, as revealed by higher plant dry weight, chlorophyll content and photochemical efficiency (Fv/Fm), and lower leaf Na+ content...
