Embedded charges for two-layer MIM are obtained from a full system calculation at the low-level. For one-layer MIM, in the absence of a full system calculation, two different types of embedded charges, namely, Geometry dependent (GD) and geometry independent (GI) charges, are used. A self-consistent procedure is employed to obtain GD charges. We have further tested our method on challenging charged systems with stronger intermolecular interactions, namely, protonated ammonia clusters (containing up to 30 ammonia molecules). The observations are similar to water clusters with improved performance using embedded charges. Overall, the performance of NPA charges as embedded charges is found to be the best.This article develops a dynamic extension of the classic model of cybersecurity investment formulated by Gordon and Loeb. In this dynamic model, results are influenced by the rate at which cybersecurity assets depreciate and the rate of return on investment. Depreciation costs are lower in the dynamic model than is implicitly assumed in the classic model, while the rate-of-return threshold is higher. On balance, the user cost of cybersecurity assets is lower in the dynamic model than is implicitly assumed in the classic model. This difference increases the economically efficient size of the cybersecurity system in value terms, increasing the efficient level of risk reduction.

A framework to design radiofrequency (RF) pulses specifically to minimize the TR of gradient echo sequences is presented, subject to hardware and physiological constraints.

Single-band and multiband (MB) RF pulses can be reduced in duration using variable-rate selective excitation (VERSE) VERSE for a range of flip angles; however, minimum-duration pulses do not guarantee minimum TR because these can lead to a high specific absorption rate (SAR). The optimal RF pulse is found by meeting spatial encoding, peripheral nerve stimulation (PNS) and SAR constraints. A TR reduction for a range of designs is achieved and an application of this in an MB cardiac balanced steady-state free-precession (bSSFP) experiment is presented. Gradient imperfections and their imaging effects are also considered.

Sequence TR with low-time bandwidth product (TBP) pulses, as used in bSSFP, was reduced up to 14%, and the TR when using high TBP pulses, as used in slab-selective imaging, was reduced by up to 72%. A breath-hold cardiac exam was reduced by 46% using both MB and the TR-optimal framework. The importance of RF-based correction of gradient imperfections is demonstrated. PNS was not a practical limitation.

The TR-optimal framework designs RF pulses for a range of pulse parameters, specifically to minimize sequence TR.

In Japan, eight genera and 46 species are known. Tick bite patients frequently present to dermatology clinics. The main causative species of human tick bites are Ixodes persulcatus and Ixodes ovatus in northern to central Japan, and Amblyomma testudinarium and Haemaphysalis longicornis in western Japan. Tick bites often occur from April to September, particularly in May through July, consistent with the active period for ticks. Although erythema usually does not develop at the tick bite site, a small area of erythema may be seen in some cases. Occasionally, an erythema larger than 50 mm in diameter are formed at the bite site, known as tick-associated rash illness. buy XL413 It is thought that the erythema is a delayed-type allergic reaction to the substances in tick saliva. Repeated tick bites induce immunoglobulin E production against galactose-1,3-α-galactose, one of the substances in tick saliva, which may trigger an immediate allergic reaction. The most reliable method to remove a tick sucking blood is en bloc resection of the tick and surrounding skin under local anesthesia. link2 Insect repellent spray containing icaridin or DEET are effective to prevent ticks from attaching and tick-borne infections. It is important to educate not only dermatologists but also the general public regarding tick bites.To investigate the effect of ursolic acid on the fetal development of gestational diabetes mellitus (GDM) caused by streptozotocin (STZ) and explore the potential mechanism for it. For the current experimental research, SD rats (pregnant animal) were used. STZ has been used to cause the diabetes mellitus in pregnant rats. Rats with evolved GDM were randomly divided and ursolic acid was given to pregnant rats in the experimental period up to 19 days in a dose-dependent manner. Blood samples and fetal rats of all group rats were collected at 19 days (pregnant rats), fetal rats and placental rats were weighted and the blood glucose, plasma insulin, C-peptide, and lipid parameters of pregnant women were estimated prior to delivery. link3 Advanced serum glycation end-products (AGEs) were estimated at regular intervals in the heart and brain of pregnant rats. Monocyte Chemoattractant Protein-1 (MCP-1), NADPH oxidase 2 (Nox2), Role of advanced glycation end product (RAGE), Vascular endothelial growth factor (VEGF), p65, ay Ursolic acid. PRACTICAL APPLICATIONS As we know that the gestational diabetes mellitus increases worldwide day by day. In the current experimental study, we try to examine the gestational diabetic effect of ursolic acid. The finding of the current study showed the gestational diabetic protective effect in the female rats via AGEs-RAGE signaling pathway. The result showed the antioxidant, anti-inflammatory, and biochemical parameters. On the basis of the result, we can say that the ursolic acid can be the protective drug for treatment of gestational diabetes mellitus.

The coronavirus disease-2019 (COVID-19) led to a large influx of critically ill patients and altered echocardiography laboratory workflow. We developed a point-of-care ultrasound (POCUS) first approach to patients requiring echocardiography and describe our workflow and findings.

We performed a single-center retrospective analysis of all POCUS studies performed on critically ill patients with COVID-19. Sonography was performed by intensivists, uploaded and archived, and rapidly reviewed by echocardiographers. We evaluated each study based on the number of views obtained. Additionally, we provide a description of the workflow during the COVID-19 surge at a tertiary care hospital in New York City.

Fifty patients had POCUS studies performed by intensivists and reviewed by echocardiographers obviating the need for sonographer-performed studies. Of the 48 cardiac POCUS studies, 17% of patients had 4 of 4 standard views available while 53% had 3 of 4 standard views. The parasternal long-axis view was obtained on 81%, subxiphoid view on 79%, apical 4-chamber view on 71%, and parasternal short-axis view on 63% of patients.

Our POCUS workflow allowed intensivists to perform cardiac sonography for rapid bedside diagnosis of pathology with immediate interpretation performed by echocardiographers. At least 3 views were obtained in the majority of cases.

To assess and compare the magnitude of lameness and level of pain after muscle-sparing lateral thoracotomy (MSLT) and standard lateral thoracotomy (SLT) in dogs.

Randomized, blinded, prospective clinical study.

Twenty-eight client-owned dogs.

The latissimus dorsi muscle was retracted in the MSLT group and was transected in the SLT group. Gait was analyzed with a force plate, and the peak vertical force symmetry index (SI) was calculated within 24 hours before surgery, 3 days postoperatively, and 8 to 12 weeks postoperatively. Symmetry index and pain scores as measured by the Glasgow Composite Measure Pain Scale - Short Form were assessed as primary outcome measures.

The SI 3 days postoperatively was lower compared with the preoperative SI value in all dogs, consistent with lameness of the ipsilateral thoracic limb (P < .001). The absolute differences in preoperative and 3-day-postoperative SI provided evidence that this change was 3.1-fold greater after SLT compared with after MSLT (P = .009). Pain scores 1 day after surgery were lower after MSLT (1) compared with after SLT (2.5, P < .001).

Lateral thoracotomies caused postoperative pain and ipsilateral forelimb lameness, and both were reduced by sparing the latissimus dorsi.

Sparing the latissimus dorsi should be considered to decrease immediate postoperative morbidity in dogs undergoing lateral thoracotomy.

Language barriers may impact family experience, which is a key measure of healthcare quality. We compared family satisfaction between Spanish-speaking families (SSF) and English-speaking families (ESF) in pediatric otolaryngology.

Retrospective cohort study.

Responses from the Family Experience Survey (FES), a hospital quality benchmarking survey, were analyzed from 2017 to 2019 at one academic pediatric otolaryngology practice. Question responses were compared between SSF versus ESF using mixed effect logistic regression models, adjusting for patient age, medical complexity, and insurance.

A total of 4,964 FES survey responses were included (14% SSF). In multivariate analysis adjusting for age, medical complexity, and insurance, SSF were 1.7 times more likely than ESF to rate their provider with the highest rating (i.e. 9-10/10; 95% confidence interval [CI] 1.24-2.22). However, SSF were less likely than ESF to provide the highest rating on many individual aspects of care, including whether providers explained things intelligibly (odds ratio [OR] 0.43, 95% CI 0.25-0.74), listened carefully (OR 0.36, 95% CI 0.28-0.47), knew their medical child's history (OR 0.53, 95% CI 0.44-0.64), provided understandable information (OR 0.36, 95% CI 0.16-0.83), spent sufficient time with them (OR 0.38, 95% CI 0.31-0.48), allowed them to discuss their questions (OR 0.57, 95% CI 0.47-0.70), or had enough input in their children's' care (OR 0.46, 95% CI 0.26-0.80).

In a large cohort of pediatric otolaryngology patients, SSF rated many individual aspects of their child's care less positively compared to ESF, despite rating their provider highly. Further research is needed to explore the reasons for these differences and how they can be improved.

To investigate the nurses' work environment in university hospitals during the COVID-19 pandemic in Brazil.

The COVID-19 pandemic brought challenging times for nurses worldwide. In Brazil, as well as in several countries, nurses are working hard in hospital settings caring for patients infected with the virus, sometimes with unfavourable work environment conditions.

This study was a convergent embedded mixed methods research. The sample comprised 104nurses from three Brazilian university hospitals. Data were collected in April-June2020 from an online questionnaire with a self-reporting Likert scale survey designed to measure the nurses' perceptions of their work environment. Qualitative data in the form of written comments were also collected through an open question. Data were analysed using descriptive statistics and content analysis.

The quantitative results showed that the responses to 'I received training on the correct use of personal protective equipment' and 'I am afraid of being infected' items had the best and worst evaluations, respectively.
