The potential role of occasional males in apomictic wasps is also discussed.Some butterfly species such as the orange oakleaf (Kallima inachus) have strikingly different colors on the dorsal (front) sides of their wings compared to those on the ventral (back) sides of their wings, which helps camouflage the butterflies from predators and attract potential mates. However, few human-made materials, devices, and technologies can mimic such differential coloring for a long time. Elimusertib ATM inhibitor Here, a new type of Janus-structured two-sided electrochromic device is developed that, upon application of different voltages, exhibits a coloration state on one side that is distinctly different from that on the other side. This is achieved by inserting an optically thin (4-8 nm) metallic layer with a complex refractive index, such as a layer composed of tungsten, titanium, copper or silver, into typical electrochromic structures.O-GlcNAcylation is a posttranslational modification considered to be a nutrient sensor that reports nutrient scarcity or surplus. Although O-GlcNAcylation exists in a wide range of cells and/or tissues, its functional role in muscle satellite cells (SCs) remains largely unknown. Using a genetic approach, we ablated O-GlcNAc transferase (OGT), and thus O-GlcNAcylation, in SCs. We first evaluated SC function in vivo using a muscle injury model and found that OGT deficient SCs had compromised capacity to repair muscle after an acute injury compared with the wild-type SCs. By tracing SC cycling rates in vivo using the doxycycline-inducible H2B-GFP mouse model, we found that SCs lacking OGT cycled at lower rates and reduced in abundance with time. Additionally, the self-renewal ability of OGT-deficient SCs after injury was decreased compared to that of the wild-type SCs. Moreover, in vivo, in vitro, and ex vivo proliferation assays revealed that SCs lacking OGT were incapable of expanding compared with their wild-type counterparts, a phenotype that may be explained, at least in part, by an HCF1-mediated arrest in the cell cycle. Taken together, our findings suggest that O-GlcNAcylation plays a critical role in the maintenance of SC health and function in normal and injured skeletal muscle.

The interplay between glycemic control and Parkinson's disease (PD) has long been recognized but not fully understood.

To investigate the association of glycated hemoglobin (HbA1c) levels with motor and cognitive symptom progression in a prospective PD cohort.

Of 244 PD patients, 17 had low HbA1c (≤30 mmol/mol), 184 were euglycemic (HbA1c 31-41 mmol/mol), 18 had high HbA1c (HbA1 ≥42 mmol/mol), and 25 had diabetes mellitus (DM). Survival analysis was applied on time until Hoehn and Yahr stage ≥3 (motor outcome) and until mild cognitive impairment.

Low HbA1c (HR 2.7; 95% CI 1.3-6; P= 0.01) as well as high HbA1c (HR 3.6; 95% CI 1.5-8.9; P= 0.005) but not DM were independent predictors of unfavorable motor outcome.

Both high and low HbA1c levels may be associated with motor symptom progression in PD; however, further studies are needed to confirm these findings and increase understanding regarding causality. © 2021 The Authors.

The Nuchal Translucency Quality Review (NTQR) program has provided standardized education, credentialing and epidemiological monitoring of nuchal translucency (NT) measurements since 2005. Our aim was to review the effect on NT measurement of provider characteristics since the program's inception.

We evaluated the distribution of NT measurements performed between January 2005 and December 2019, for each of the three primary performance indicators of NT measurement (NT median multiples of the median (MoM), SD of log

NT MoM and slope of NT with respect to crown-rump length (CRL)) for all providers within the NTQR program with more than 30 paired NT/CRL results. Provider characteristics explored as potential sources of variability included number of NT ultrasound examinations performed annually (annual scan volume of the provider), duration of participation in the NTQR program, initial credentialing by an alternative pathway, provider type (physician vs sonographer) and number of NT-credentialed providers s within the practice are all associated with outcome metrics indicating quality of performance. It is critical that providers participate in ongoing quality assessment of NT measurement to maintain consistency and precision. Ongoing assessment programs with continuous feedback and education are necessary to maintain quality care. © 2021 International Society of Ultrasound in Obstetrics and Gynecology.

Detection of free light chains (fLC) in animals relies on protein electrophoresis or the Bence-Jones protein test on urine.

To describe the detection of both serum fLC (sfLC) and urine fLC (ufLC) in 8 dogs and 2 cats using a commercially available human immunofixation (IF) kit.

Archived serum or urine samples from 27 dogs and 2 cats submitted to the Colorado State University Veterinary Diagnostic Laboratory for routine diagnostics.

Retrospective study evaluating the presence of fLC in dogs and cats using agarose gel electrophoresis and routine and fLC IF performed on serum and urine. The performance of the fLC IF reagents was evaluated using samples characterized by routine IF, tandem mass spectrometry, and a combination of fLC IF and western blotting. Free light chains were documented by paired electrophoresis and fLC IF.

The fLC only myeloma case developed end-stage renal failure 5 months post initial diagnosis. All electrophoresis-defined urinary Bence-Jones proteins were labeled by the anti-free λ light chain (anti-fλ) reagent; none were labeled by the anti-free κ light chain (anti-fκ); 2 of these were identified as fκ by mass spectrometry. An electrophoretically identical protein restriction that was labeled by the anti-fλ reagent was present in the paired serum from 5/8 of cases, documenting sfLC.

Commercially available human IF reagents identified sfLC and ufLC in both dogs and cats. Free light chains may be nephrotoxic in dogs.

In the absence of echocardiography, identification of cardiomegaly via thoracic radiography is a necessary criterion for classification of disease severity in dogs with myxomatous mitral valve disease (MMVD).

Modified-vertebral left atrial size (M-VLAS) facilitates objective radiographic assessment of the left atrium (LA) in 2 dimensions and identifies LA enlargement more accurately than existing methods.

Sixty-four dogs with various stages of MMVD and 6 control healthy dogs.

Retrospective case-control study. Medical records were searched for dogs with varying severity of MMVD. Modified-vertebral left atrial size, vertebral left atrial size (VLAS), vertebral heart size (VHS), and radiographic left atrial dimension (RLAD) were measured from thoracic radiographs and compared with echocardiographically derived measurements.

Positive correlation to LA/Ao was identified for M-VLAS (r = 0.77, P < .001), VLAS (r = 0.76, P < .001), RLAD (r = 0.75, P < .001), and VHS (r = 0.67, P < .001). Receiver operating characteristic analyzes provided an area under the curve of 0.97 (95% CI, 0.94-1.00) for M-VLAS, which was superior to VHS (0.90, 95% CI, 0.94-1.00, P = .03) in identifying dogs with LA/Ao ≥1.6. A cut-off value of ≥3.4 vertebrae using M-VLAS provided 92.7% sensitivity and 93.1% specificity in predicting LA enlargement.

M-VLAS, which is superior to VHS, offers an accurate and repeatable way to radiographically identify LA enlargement in dogs with MMVD.

The main objective was to describe metastatic and survival rates in patients with small choroidal melanocytic lesions initially managed by observation.

Retrospective, observational study of consecutive cases recruited from 2001 through 2018, followed for a median (mean, range) of 81.0 (89.3, 10-204) months in a tertiary referral centre for ocular oncology. Seventy-five consecutive patients diagnosed with small choroidal melanocytic lesions with risk factors for growth initially observed and who showed progression during follow-up. Treatment was performed (plaque radiotherapy or enucleation in 96% and 4% of cases, respectively) at detection of tumour growth.

Median (mean, range) tumour thickness was 2.2 (2.23, 1.08-3.40) mm, and median maximum basal diameter was 8.5 (8.16, 4-12) mm. At diagnosis, a median (mean, range) of 5 (5.48, 1-8) risk factors for progression were present. Lesions grew at a median (mean, range) rate of 0.42 mm/y (1.12, 0-7.68) in thickness and 1.05 mm/y (3.14, 0-4.8) in maximum diameter. Median (mean, range) time until growth was 17.00 (32.6, 1-161) months post-diagnosis, at which time tumours were treated. Five patients developed local recurrence after brachytherapy requiring enucleation. Four patients developed hepatic metastasis. Melanoma-specific survival was 98% at 5 years (95% CI, 94.2-100%) and 91.6% (95% CI, 82-100%) at 10 and 15 years.

In small melanocytic lesions with risk factors for growth, initial observation until detection of tumour growth results in a seemingly low risk of metastasis, suggesting that this may be an initial approach to consider in tumours with indeterminate malignant potential.

MicroPure is an ultrasound imaging technology used for detecting microcalcifications. This study aimed to evaluate the usefulness of the Firefly sign in ultrasonic MicroPure imaging for detecting the vulnerability of carotid plaques.

Ultrasonic grey-scale imaging was used to detect carotid plaques. Ultrasonic MicroPure imaging was used to detect the Firefly sign and to determine the location and number of Firefly signs.

A total of 142 plaques were detected in 72 patients, and 62.0% were Firefly-positive plaques. The length or thickness, the risk of rupture and the percentage of vulnerable plaques were greater in the Firefly-positive plaques than in Firefly-negative plaques. The assessment of plaque vulnerability built on the 4-point Firefly scoring system showed that the area under the ROC curve was 0.750 (P <.001). The sensitivity and specificity of vulnerable plaques with a score of 2 points were 71.9 and 73.6%, respectively.

The Firefly signs are widely present in carotid atherosclerotic plaques and can be detected with ultrasonic MicroPure imaging.
