Long-term treatment with active vitamin D [1α,25(OH)2 D3 ] and its derivatives is effective for increasing bone mass in patients with primary and secondary osteoporosis. Derivatives of 1α,25(OH)2 D3 , including eldecalcitol (ELD), exert their actions through the vitamin D receptor (VDR). ELD is more resistant to metabolic degradation than 1α,25(OH)2 D3 . It is reported that ELD treatment causes a net increase in bone mass by suppressing bone resorption rather than by increasing bone formation in animals and humans...

The PAMONO-sensor (plasmon assisted microscopy of nano-objects) demonstrated an ability to detect and quantify individual viruses and virus-like particles. However, another group of biological vesicles-microvesicles (100-1000 nm)-also attracts growing interest as biomarkers of different pathologies and needs development of novel techniques for characterization. This work shows the applicability of a PAMONO-sensor for selective detection of microvesicles in aquatic samples. The sensor permits comparison of relative concentrations of microvesicles between samples...

Prostate cancer patients often receive androgen deprivation therapy (ADT) in combination with radiation therapy (RT). Recent evidence suggests that both ADT and RT have immune modulatory properties. First, ADT can cause infiltration of lymphocytes into the prostate, although it remains unclear whether the influx of lymphocytes is beneficial, particularly with the advent of new classes of androgen blockers. Second, in rare cases, radiation can elicit immune responses that mediate regression of metastatic lesions lying outside the field of radiation, a phenomenon known as the abscopal response...

A pattern-based classification system has recently been proposed for invasive endocervical adenocarcinoma (EAC), which is predictive of the risk for lymph node metastases (LNM). The main utility of the system lies in separating cases with very low risk for LNM (pattern A) from those with higher risk (pattern B and C). Different growth patterns (GPs) are found in pattern C cases. The aim of the study was to evaluate the effect of GP on the behavior of pattern C EAC. By reevaluating 189 pattern C EACs, we documented 6 architectural GPs: diffuse destructive (DD), confluent (CON), extensive linear destructive (ELD), band-like lymphocytic infiltrate (BLL), solid (SOL), and micropapillary (MP)...

Idiopathic normal pressure hydrocephalus (iNPH) is a progressive clinical syndrome that includes gait disturbances, urinary incontinence, and cognitive impairment. iNPH shows similarities to other neurodegenerative disorders, primarily Alzheimer's Disease (AD). Definition of the neuropsychological profile of iNPH and the qualitative analysis of systematic mistakes made in cognitive tests could represent a valid method for systematizing possible specific markers of iNPH dementia and differentiating it from other dementias...

Global aphasia without hemiparesis is a rare condition often associated with embolic stroke. Posttraumatic causes have not been reported, in the literature, to our knowledge. We report a 15-year old boy with transient global aphasia without hemiparesis due to blunt head trauma. In our case, clinical findings occurred 1week later following head trauma. Emergence of the symptoms after a period of the first mechanical head trauma, draws attention to the importance of secondary process in traumatic brain injury...

The quantification of drugs in biological samples is a significant task for determination of the physiological efficiency in evaluated drugs in the drug discovery. To analysis of the chemical compounds at the trace and ultratrace levels, adequate analytical procedures should be applied. Therefore, sample preparation method undoubtedly is the most important stage in the trace determination process. In spite of the great growth of analytical instrumentation during the recent years, sample preparation is still nowadays considered the impasse of the all analytical procedure, especially in drugs analysis...

Keratoacanthoma (KA) is a subtype of squamous cell carcinoma whose development has been linked to excessive sun exposure, immunosuppression, and trauma. Given the rapidly expanding therapeutic armamentarium for anti-aging modalities in dermatology, reports of KA secondary to invasive cosmetic procedures are on the rise. We present a case of eruptive KAs after full- eld ablative Erbium:YAG 2940 nm laser resurfacing of the face that resolved with minimal intervention. This case demonstrates the potential for a rare yet signi cant laser complication that may warrant discussion during the consenting process...

BACKGROUND: Increasing demand for non-invasive skin tightening and body contouring procedures has led to several technological in- novations in energy-based devices such as ultrasound, radiofrequency and cryolipolysis. An emerging trend in the eld is to evaluate whether combination therapies for skin laxity/body contouring using energy-based devices can deliver superior clinical results and patient satisfaction. As such, the objective of this prospective, internal-controlled, blind clinical study was to assess the safety and efficacy of cryolipolysis followed by multipolar radiofrequency with pulsed electromagnetic elds (PEMF) and adjustable pulsed suction for the treatment of skin laxity in the flanks...

"Fractionated photodynamic therapy (PDT)" is a new term being used by dermatologists to describe advances in PDT technology including fractionated light or the adjuvant use of fractional lasers. Although dermatologists have used PDT since the early 1990s for the treatment of photodamage and precancerous lesions, newer developments in technology have allowed for the treatment of non-melanoma skin cancers (NMSCs), in ammatory disorders, and even uses in the eld of anti-aging. Recent developments in fractionated light therapy have allowed for PDT with dark intervals and two-fold illumination schemes to increase cellular damage and apoptosis...

Rotational dynamics of quantum state selected and unselected CH3I molecules in intense femtosecond laser fields has been studied. The orientation and alignment evolutions are derived from a pump-probe measurement and in good agreement with the numerical results from the time-dependent Schrödinger equation (TDSE) calculation. The different rotational transitions through nonresonant Raman process have been assigned from the Fourier analysis of the orientation and alignment revivals. These revivals are derived from a pump-probe measurement and in good agreement with the numerical results from the TDSE calculation...

BACKGROUND: Polyploidy and hybridization are both recognized as major forces in evolution. Most of our current knowledge about differences in gene regulation in polyploid hybrids comes from plant studies. The gene expression of diverged genomes and regulatory interactions are still unclear in lower vertebrates. RESULTS: We generated 229 million cleaned reads (42.23 Gbp) from triploid of maternal grass carp (Ctenopharyngodon idellus, Cyprininae, 2n = 48) × paternal blunt snout bream (Megalobrama amblycephala, Cultrinae, 2n = 48) and their diploid parents using next-generation sequencing...

N-terminally truncated (96-585) GAD65 (tGAD65) autoantibodies may better delineate type 1 diabetes than full-length GAD65 (fGAD65) autoantibodies. We aimed to compare the diagnostic sensitivity and specificity between fGAD65 and tGAD65 autoantibodies for type 1 diabetes in relation to HLA-DQ. Sera from newly diagnosed type 1 diabetes children and adolescents (n=654) and healthy controls (n=605) were analyzed in radiobinding assays for fGAD65 (fGADA), tGAD65 (tGADA) and commercial (125)I-GAD65 (RSRGADA) autoantibodies...

OBJECTIVES: Normal pressure hydrocephalus (NPH) is a treatable neurological disorder that appears in older adults, lacks specific diagnostic criteria, and resembles symptoms seen in Alzheimer's disease (AD). Presently, differentiating NPH from AD in the early stages of symptom presentation remains difficult. This study established whether olfactory testing may be useful in this regard. In addition, we determined whether olfactory function of NPH patients differed before and after extended lumbar drainage (ELD), as well as six months after surgical implantation of a ventriculoperitoneal (VP) shunt...

: Viruses are under relentless selective pressure from host immune defenses. To study how poxviruses adapt to innate immune detection pathways, we performed serial vaccinia virus infections in primary human cells. Independent courses of experimental evolution with a recombinant strain lacking E3L revealed several high-frequency point mutations in conserved poxvirus genes, suggesting important roles for essential poxvirus proteins in innate immune subversion. Two distinct mutations were identified in the viral RNA polymerase gene A24R, which seem to act through different mechanisms to increase virus replication...

The incidence of type 1 diabetes (T1D) has substantially increased over the past decade, suggesting a role for non-genetic factors such as epigenetic mechanisms in disease development. Here we present an epigenome-wide association study across 406,365 CpGs in 52 monozygotic twin pairs discordant for T1D in three immune effector cell types. We observe a substantial enrichment of differentially variable CpG positions (DVPs) in T1D twins when compared with their healthy co-twins and when compared with healthy, unrelated individuals...
