Testicular melanotic neuroectodermal tumor of infancy (MNTI) is extremely rare, with 2 cases reported in the literature. Its rarity and rapid and infiltrative growth pattern pose a diagnostic challenge. A previously healthy 3-month-old male, presented with a history of worsening left hemiscrotal swelling for 1 week. An outside ultrasound was suggestive of testicular torsion. Left orchiectomy demonstrated a mass occupying almost entire testicle with a variegated cut surface, with areas of pigmentation, necrosis, and hemorrhage...

Obstructive sleep apnea (OSA) has many serious consequences, and one of these may be the exacerbation of type 2 diabetes mellitus (T2DM). Reports on the effect of continuous positive airway pressure (CPAP) on glucose metabolism in people with T2DM and OSA are conflicting. Therefore, the purpose of this review was to examine the effect of CPAP treatment on glucose metabolism by synthesizing findings from randomized controlled trials. The PRISMA review protocol was developed and registered in PROSPERO. A systematic search of PubMed, CINAHL, Embase, Web of Science, PsycInfo, and Cochrane was conducted from inception to March 2017...

A 50-year-old woman (gravida 2, para 2) first noticed a small nodule in the right labium majus 2 years prior to the initial visit to the Hachinohe Red Cross Hospital (Hachinohe, Japan), which had gradually increased in size. On physical examination, a well-circumscribed, elastic, firm, goose egg-sized, subcutaneous mass protruding from the right labium majus was identified. On magnetic resonance imaging (MRI), the lesion was hypointense on T1-weighted images and was well-circumscribed, strongly enhanced and homogeneous on gadolinium-enhanced images, measuring 7...

The association of fasting glucose with the risk of death according to sex and age remains unclear, and insufficient information is available on sex- and age-specific glucose concentrations within ethnic groups. This study analyzed a sample of 12,455,361 Korean adults who participated in health examinations during 2001-2004, and were followed up until 2013. Men had 3.0 mg/dL (0.167 mmol/L) higher mean glucose concentrations than women (94.7 vs. 91.7 mg/dL), although women over 73 years had higher levels...

BACKGROUND: Associations between sleep duration and type 2 diabetes (T2D) risk markers in childhood have been little studied. We examined associations between self-reported sleep duration and T2D risk markers in children. METHODS: Cross-sectional study of 4525 multiethnic UK children aged 9 to 10 years. Sleep time was calculated from self-reported usual time of going to bed and getting up on a school day, validated in a subset using accelerometers. Fasting blood samples provided levels of serum lipids and insulin, plasma glucose, and HbA1c...

BACKGROUND: Metabolic syndrome (MetS) is strongly associated with cardiovascular disease. With MetS prevalence rates increasing in the U.S. population, prevention efforts have largely focused on diet and exercise interventions. Before retirement, military service members have met fitness requirements for at least 20 years, and have lower MetS rates compared to age-matched U.S. population controls (23.4% vs. 39.0%), which suggests a protective effect of the lifestyle associated with military service...

Sperm hyper-activation is a dramatic change in sperm behavior where mature sperm burst into a final sprint in the race to the egg. The mechanism of sperm hyper-activation in many metazoans, including humans, consists of a jolt of Ca2+ into the sperm flagellum via CatSper ion channels. Surprisingly, all nine CatSper genes have been independently lost in several animal lineages. In Drosophila, sperm hyper-activation is performed through the cooption of the polycystic kidney disease 2 (pkd2) Ca2+ channel. The parallels between CatSpers in primates and pkd2 in Drosophila provide a unique opportunity to examine the molecular evolution of the sperm hyper-activation machinery in two independent, nonhomologous calcium channels separated by > 500 million years of divergence...

REVIEW
Maud Deruaz, Andrew M Tager
Antiretroviral therapy can efficiently control HIV viral replication, resulting in low viral loads and sustained CD4(+) T cell counts in HIV-infected persons. However, fast viral rebound occurs in most infected persons when therapy is interrupted. The principal component of persistent infection is a latent but replication-competent HIV reservoir. The long half-life of this reservoir is a major barrier to cure, and its elimination is the target of important research efforts. Animal models that can recapitulate this aspect of human infection are needed to examine the HIV reservoir in tissues in vivo, and to test eradication strategies...

Josué Tago, Antonio Hernández-Espriú
In the oil and gas industry, well test analysis using derivative plots, has been the core technique in examining reservoir and well behavior over the last three decades. Recently, diagnostics plots have gained recognition in the field of hydrogeology; however, this tool is still underused by groundwater professionals. The foremost drawback is that the derivative function must be computed from noisy field measurements, usually based on finite-difference schemes, which complicates the analysis. We propose a B-spline framework for smooth derivative computation, referred to as Constrained Quartic B-Splines with Free Knots...

The fatigue behavior of a cellular composite with an epoxy matrix and glass foam granules is analyzed and modeled by means of continuum damage mechanics. The investigated cellular composite is a particular type of composite foam, and is very similar to syntactic foams. In contrast to conventional syntactic foams constituted by hollow spherical particles (balloons), cellular glass, mineral, or metal place holders are combined with the matrix material (metal or polymer) in the case of cellular composites. A microstructural investigation of the damage behavior is performed using scanning electron microscopy...

Based on the Nottingham criteria, the number of mitosis cells in histopathological slides is an important factor in diagnosis and grading of breast cancer. For manual grading of mitosis cells, histopathology slides of the tissue are examined by pathologists at 40× magnification for each patient. This task is very difficult and time-consuming even for experts. In this paper, a fully automated method is presented for accurate detection of mitosis cells in histopathology slide images. First a method based on maximum-likelihood is employed for segmentation and extraction of mitosis cell...

Passive loading as a novel screening approach is a material-saving tool for the efficient selection of a suitable colloidal lipid carrier system for poorly water soluble drug candidates. This method comprises incubation of preformed carrier systems with drug powder and subsequent determination of the resulting drug load of the carrier particles after removal of excess drug. For reliable routine use and to obtain meaningful loading results, information on the kinetics of the process is required. Passive loading proceeds via a dissolution-diffusion based mechanism, where drug surface area and drug water solubility are key parameters for fast passive loading...

Working in crime scenes presents a challenge to the forensic scientist, as some surfaces, such as floors and walls, cannot be transferred to the lab for further development and must, therefore, be processed at the crime scene itself. Two main types of latent fingermarks may be encountered in crime scenes: amino acids based and blood contaminated. One of the most common reagents, which are able to develop both types of fingermarks on porous surfaces, is ninhydrin. As blood contaminated fingermarks may be crucial in connecting the suspect to the crime it is important to be able to distinguish between them and natural fingermarks...
