A 20-month-old female spayed Staffordshire Terrier (22.3 kg) presented to the Orthopedic Surgery Service at North Carolina State University Veterinary Teaching Hospital for evaluation of a 6-week history of toe-touching to nonweight-bearing lameness in the right hind limb. Radiographs of the right stifle revealed a multiloculated lytic lesion of the distal femur, with a large open lytic zone centrally, numerous osseous septations peripherally, and focal areas of cortical thinning and loss. An aspirate of the right distal femoral lesion yielded mildly cloudy serosanguineous fluid...

Nowcasting model for online monitoring of personal outdoor behaviour is proposed. It is envisaged that it will provide an effective e-tool used by smartphone users. The model could estimate maximum duration of safe (without erythema risk) outdoor activity. Moreover, there are options to estimate duration of sunbathing to get adequate amount of vitamin D3 and doses necessary for the antipsoriatic heliotherapy. The application requires information of starting time of sunbathing and the user's phototype. At the beginning the user will be informed of the approximate duration of sunbathing required to get the minimum erythemal dose, adequate amount of vitamin D3 , and the dose necessary for the antipsoriatic heliotherapy...

According to a famous hypothesis, Viking sailors could navigate along the latitude between Norway and Greenland by means of sky polarization in cloudy weather using a sun compass and sunstone crystals. Using data measured in earlier atmospheric optical and psychophysical experiments, here we determine the success rate of this sky-polarimetric Viking navigation. Simulating 1000 voyages between Norway and Greenland with varying cloudiness at summer solstice and spring equinox, we revealed the chance with which Viking sailors could reach Greenland under the varying weather conditions of a 3-week-long journey as a function of the navigation periodicity Δ t if they analysed sky polarization with calcite, cordierite or tourmaline sunstones...

It has been speculated that the unitary eyes of vertebrates and molluscs, and the compound eyes of insects and crustaceans, evolved separately. On the other hand, the common use of rhodopsin as a photoreceptor molecule, and the conservation of Pax6 as a master control gene for eye development, suggest instead that the eye evolved once. Yet, recently the molecular genetics that had seemed to suggest a definitive answer to this evolutionary point has once again become cloudy. Here we propose an alternative approach to addressing the question of eye evolution through comparative analyses of physiological optics...

A 67-year old woman who had received treatment with prednisolone for systemic scleroderma visited our hospital. She complained of mild abdominal pain, bloating, anorexia, watery stools (approximately three times a day). Abdominal computed tomography showed high contrast appearance and thickening of the entire small intestinal wall as well as accumulation of intestinal fluid with no mechanical obstruction (Figure 1). Capsule endoscopy (Figure 2a) and antegrade double-balloon endoscopy (Figure 2b) revealed retention of cloudy intestinal fluid throughout the entire small intestine with reddish and edematous mucosa...

In this study, we report on the performance of satellite-based photosynthetically available radiation (PAR) algorithms used in published oceanic primary production models. The performance of these algorithms was evaluated using buoy observations under clear and cloudy skies, and for the particular case of low sun angles typically encountered at high latitudes or at moderate latitudes in winter. The PAR models consisted of (i) the standard one from the NASA-Ocean Biology Processing Group (OBPG), (ii) the Gregg and Carder (GC) semi-analytical clear-sky model, and (iii) look-up-tables based on the Santa Barbara DISORT atmospheric radiative transfer (SBDART) model...

Background: Peritoneal tuberculosis (TB) is a relatively uncommon presentation of extrapulmonary TB. Early diagnosis of peritoneal TB is difficult because of its nonspecific clinical manifestation such as abdominal pain, fever, or ascites. Especially early after surgery of abdomen or pelvis, these symptoms can be misdiagnosed as septic peritonitis. There are few reports of peritoneal TB as a postoperative complication of laparoscopic surgery. Here, we describe a first case of peritoneal TB after robot-assisted laparoscopic prostatectomy (RALP) with extended lymph node dissection...

Acute appendicitis in peritoneal dialysis patients generally presents as abdominal pain and cloudy dialysate. We report a case of acute appendicitis in a peritoneal dialysis patient that presented as poor dialysate fluid drainage and an abnormal abdominal X-ray showing breakage in the continuity of the catheter. Catheter dysfunction in this case was caused by acute appendicitis leading to the formation of adhesions with peritoneal dialysis catheter trapped in it. This resulted in radiological appearance of catheter breakage, although catheter itself was intact...

Uterine illnesses are the major problem in horse reproductive programs. The diagnosis of these pathologies is often neglected or does not provide enough information about the cause. The aim of this study was to evaluate different diagnoses to provide more accurate information about endometritis and the real endometrial profile at the beginning of a breeding season. Fifty-one mares with reproductive failure were evaluated. Two different uterine cytology diagnoses, culture of uterine flush material and biopsy assay, were performed...

Stimuli-responsive polymers have received increasing interest for a variety of applications. Here, we report a series of unique charge-determined thermoresponsive polypeptoids synthesized by a combination of ring-opening polymerization and click chemistry. The LCST-type and UCST-type behavior is mainly dominated by the charge state on the side chain. Further, the phase transition temperature highly depends on the degree of polymerization, the side-chain architecture, the pH value, and so on. The obtained polypeptoid solutions exhibit good stability against temperature and salt concentration...

Purpose: To evaluate the efficacy, safety, and injection frequency of vascular endothelial growth factor (VEGF) antagonists in the treatment of macular edema secondary to retinal vein occlusion (RVO) in clinical practice. Patients and methods: A multicenter retrospective study of the medical records of 165 patients (95 branch RVO, 70 central RVO) treated with at least three anti-VEGF injections in the study eye was conducted. Available data collected for at least 6 months after the first injection included Snellen best-corrected visual acuity (BCVA), central retinal thickness (CRT) by time-domain optical coherence tomography (TD-OCT) or spectral-domain optical coherence tomography (SD-OCT), anti-VEGF injections, other treatments/procedures for RVO, and adverse events...

In this study, gellan gums with different acyl contents were prepared, and their effects on blueberry cloudy juices were compared. The rheological properties, stability coefficients, sedimentations, color parameters and particle size distributions of blueberry cloudy juices with 0.035% (w/w) of gellan gum were measured. As the acyl content increased, the viscosity increased, and the sedimentation and stability coefficient values decreased. Gellan gums with higher acyl contents provided better beverage stabilizing capabilities through stricter enforcement of the molecular associations...

BACKGROUND: ST-elevation acute myocardial infarction (STEMI) represents one of the leading causes of death. The time of STEMI onset has a circadian rhythm with a peak during diurnal hours, and the occurrence of STEMI follows a seasonal pattern with a salient peak of cases in the winter months and a marked reduction of cases in the summer months. Scholars investigated the reason behind the winter peak, suggesting that environmental and climatic factors concur in STEMI pathogenesis, but no studies have investigated whether the circadian rhythm is modified with the seasonal pattern, in particular during the summer reduction in STEMI occurrence...

Suicide is a serious public health problem around the world. Since the nineteenth century, the impact of socio-environmental factors on suicide has attracted much public attention, especially in the context of global climate change. We have performed a retrospective correlation study that analyzes the demographic pattern of suicide in Cantabria, a northern coastland region of Spain. Moreover, we have created a multivariable binomial regression model to study the relationship between suicide and environmental factors (atmospheric pollutants and meteorological variables) among January 1, 2000, and December 31, 2013 in the province...

Intestinal perforation by a peritoneal catheter is an uncommon, but serious, complication that has a high mortality rate. Intestinal perforation in peritoneal dialysis (PD) patients is difficult to diagnose using symptoms and radiological findings, which may result in a delay in diagnosis. Moreover, intestinal perforation complicated with fungal peritonitis is reportedly a severe condition with a poor prognosis. Herein, we report the case of a 78-year-old man on PD, whose diagnosis of perforative peritonitis was difficult to diagnose preoperatively...

Aerosol is an important component of the atmosphere that affects the environment, climate, and human health. Remote sensing is an efficient observation method for monitoring global aerosol distribution and changes over time. The daily Moderate Resolution Imaging Spectroradiometer (MODIS) level-2 aerosol optical depth (AOD) (Collection 6) product (10 km resolution) is often used to study climate change and air pollution. However, the product is prone to yielding large amounts of data gaps due to the unfeasibility of retrieving reliable estimates under cloudy conditions, and these data gaps inevitably affect the results and analysis of the product's application...

Active cloud observations from A-Train's CloudSat and CALIPSO satellites offer new opportunities to examine the vertical structure of hydrometeor layers. We use the 2B-CLDCLASS-LIDAR merged CloudSat-CALIPSO product to examine global aspects of hydrometeor vertical stratification. We group the data into major Cloud Vertical Structure (CVS) classes based on our interpretation of how clouds in three standard atmospheric layers overlap, and provide their global frequency of occurrence. The two most frequent CVS classes are single-layer (per our definition) low and high clouds which represent ~53% of cloudy skies, followed by high clouds overlying low clouds, and vertically extensive clouds that occupy near-contiguously a large portion of the troposphere...

In the fruit juice industry, high pressure (HP) processing has become a commercial success. However, enzymatic browning, cloud loss, and flavor changes during storage remain challenges. The aim of this study is to combine kiwifruit puree and HP pasteurization (600 MPa/3 min) to stabilize cloudy apple juice during storage at 4 °C. A wide range of targeted and untargeted quality characteristics was evaluated using a multivariate approach. Due to high ascorbic acid content and high viscosity, kiwifruit puree allowed to prevent enzymatic browning and phase separation of an apple-kiwifruit mixed juice...
