our inference that natural selection might have played a major role, while mutation pressure had a minor role in shaping the CUB of cp genes. The magnitudes of mutation pressure and natural selection on cp genes varied across Oryza species.

Open reduction and internal fixation through the Kocher-Langenbeck approach is the treatment of choice for selected acetabular fracture patterns. Patient positioning (lateral vs prone) can affect the outcome and post-operative complications.

A retrospective cohort of seventy-three adult patients' with acetabular fractures treated with open reduction and internal fixation through the Kocher-Langenbeck approach in either prone or lateral position. Primary outcome was the quality of radiographic fracture reduction; secondary outcomes included operative time, intra-operative estimated blood loss and pre-operative complications.

The demographics and fracture type were similar between the two groups. There was no difference in the quality of reduction using the Matta radiographic grading. Laterally positioned group demonstrated significant shorter surgical time and lower incidence of iatrogenic sciatic nerve injury. There was no difference in estimated blood loss, heterotopic ossification or infection.

This study showed no difference in the quality of fracture reduction, intraoperative blood loss, post-operative infection and heterotopic ossification between both groups. Hence, patients' condition, surgeon experience and preference are important factors for deciding patient positioning in the Kocher-Langenbeck approach for acetabulum fracture fixation.

Leuconostoc spp. belongs to the group of lactic acid bacteria as one of the predominant members and are relevant not only in varied food fermentations, but also can be employed in the production of extracellular homopolysaccharides (HoPS) such as α-glucans (dextran, alternan) and β-fructans (levan,inulin) from the sucrose-containing substrates. EPS are synthesized by specific Leuconostoc spp. extracellular glycosyltransferases [dextran sucrase, alternansucrase (ASR)] and fructosyltransferases (levansucrase, inulosucrase) and enzymatic reactions can be performed in whole culture systems as well as using cell-free enzymes. Both α-glucans and β-fructans have a wide range of properties, mostly depending on their pattern of linkages, which, although differing in some respects, make suitable prerequisites for their versatile application in many fields, especially in the food industry and biomedicine. As a rule, these properties (polymer type, molecular mass, rheological parameters), as well as the overall EPS yield, are strain-specific for the selected producers and depend to a large extent on the nutritional and growth conditions used, which in many cases remain not sufficiently optimized for Leuconostoc spp. This review summarizes the current knowledge on the potential of Leuconostoc spp. to produce commercially relevant EPS, including information on their applications in various fields, producer strains, production methods and techniques used, selected conditions, the productivity of bioprocesses as well as the possible use of renewable resources for their development.The aim of this study is to explore the impact of the COVID-19 pandemic on pregnant women's anxiety and identify factors most strongly associated with greater changes in anxiety. An anonymous, online, survey of pregnant women (distributed April 3-24, 2020) included a modified pregnancy-related anxiety scale (PRAS) reflecting respondents' perception of pregnancy anxiety before COVID-19 and a current assessment of pregnancy-related anxiety. read more between these scores was used as the outcome variable. Data were analyzed using bivariate and multivariate linear regression analyses. Two thousand seven hundred forty pregnant women from 47 states completed the survey. #link# 25.8% (N = 706) stopped in-person visits, 15.2% used video visits (N = 415), and 31.8% (N = 817) used phone visits for prenatal care as a result of COVID-19. Those planning a hospital birth dropped from 2641 (96.4%) to 2400 (87.7%) following COVID-19. More than half of women reported increased stress about food running out (59.2%, N = 1622), losing a job or household income (63.7%, N = 1745), or loss of childcare (56.3%, N = 1543). More than a third reported increasing stress about conflict between household members (37.5%, N = 1028), and 93% (N = 2556) reported increased stress about getting infected with COVID-19. Slightly less than half of respondents (either selves or family members) were healthcare workers (41.4%, N = 1133) or worked in essential services (45.5%, N = 1246). In multivariate analysis, those reporting higher agreement with COVID-19-related stressors had greater changes in pre- to post-COVID-19 pregnancy-related anxiety. link2 The COVID-19 pandemic is profoundly affecting pregnant women's mental health, and factors independent of pregnancy appear to be driving changes in pregnancy-specific anxiety.

This randomized, controlled, pilot study assessed the outcome of non-surgical primary/secondary root canal treatments either with a novel bioactive sealer and the single-cone technique or with gutta-percha, zinc oxide-eugenol sealer (ZOE), and warm vertical compaction.

Sixty-nine patients were randomly divided into two groups that were treated using the single-cone technique with BioRoot

RCS (Septodont) (BIO group) or warm vertical compaction with gutta-percha and ZOE sealer (PCS group). Two subsamples (BIOAP and PCSAP) comprised the cases with apical periodontitis. Treatment was undertaken by four residents using a standardized instrumentation and disinfection protocol. The periapical index (PAI) was recorded, and clinical and radiographic follow-up performed at 1, 3, 6, and 12 months. Treatment success was assessed according to "periapical healing" and "tooth survival". The test for the equality of proportions, t tests for the equality of means, and non-parametric K-sample tests for the equality of medians were applied when appropriate.

The survival rate was similar in the BIO and PCS (p = 0.4074) and the BIOAP and PCSAP groups (p = 0.9114). The success rate was higher in the BIO groups, but not statistically significant (p = 0.0735). In both BIOAP and PCSAP groups, a progressive decrease in the PAI was observed.

At 12 months, both techniques showed reliable results. Further studies and longer follow-ups are needed.

This study documents the feasibility of using a bioactive sealer in conjunction with the single-cone technique to obturate the root canal and obtaining a predictable outcome.

The objective of this study was to retrospectively evaluate the association between background parenchymal enhancement (BPE) on contrast-enhanced ultrasound (CEUS) with Sonazoid

and patient characteristics. Additionally, background parenchymal tissues with the high-contrast effect were pathologically observed compared to those showing the low-contrast effect.

A total of 65 patients who underwent breast CEUS with Sonazoid

between January 2010 and November 2013 were enrolled. Regions of interest (ROIs) were put on the tumor and on the background parenchymal tissue. link3 The dB values during the nonenhanced time and at peak contrast enhancement were measured based on the time intensity curve (TIC) drawn by the ROI. The differences in the dB values of pre- and post-enhanced time were obtained separately for ROIs on the tumor and ROIs on the parenchymal tissue. The patient characteristics studied were age, menstrual status, mammographic density, BPE on magnetic resonance imaging (MRI), and pathological diagnoses of breast tumors.

There was a weak negative correlation between BPE on CEUS and age. As for the contrast effect of parenchymal tissue, there was a significant difference between the menstruating and menopausal groups. There was no significant difference among the levels of mammographic density, and among the degrees of contrast effect on MRI. BPE on CEUS was the same between those with a malignant tumor and those with a benign tumor in each menstrual status. The parenchymal tissue with the low-contrast effect showed pathological atrophy.

The degree of BPE on CEUS appeared related to age, menstruating or menopausal, and atrophy of breast tissue. BPE on CEUS was the same between those with a malignant tumor and those with a benign tumor in each menstrual status.

Conventional blood cultures take 24-72 h. The polymerase chain reaction (PCR)-based methods give faster results (2-3 h) but need expensive thermal cyclers. We therefore developed an isothermal recombinase polymerase amplification (RPA) combined with lateral flow dipstick (LFD) assay for rapid detection of MRS in spiked blood culture samples. Fifty-six clinical isolates including 38 mecA-carrying staphylococci and 18 non-mecA-carrying organisms as confirmed by PCR methods were studied. RPA primer set and probe specific for mecA gene (encoding penicillin-binding protein 2a) were designed. RPA reaction was carried out under isothermal condition (45 °C) within 20 min and read by LFD in 5 min. The RPA-LFD provided 92.1% (35/38) sensitivity for identifying MRS in positive blood culture samples, and no cross-amplification was found (100% specificity). This test failed to detect three mecA-carrying S.sciuri isolates. The detection limits of RPA-LFD method for identifying MRS were equal to those of PCR method. The RPA-LFD is simple, fast, and user-friendly. This method could detect the mecA gene directly from the positive blood culture samples without requirement for special equipment. This method would be useful for appropriate antibiotic therapy and infection control, particularly in a low-resource setting.Calcification is a major failure mode of bioprosthetic heart valves. So far, cost and time saving in vitro analyses of calcification potentials are unreliable, mostly due to superficial or spontaneous precipitation of the applied fluids. In this study, we developed a near-physiological non-spontaneously precipitating fluid for an accelerated in vitro calcification assessment, and validated it by analyzing the calcification potential of two prosthetic materials within two reference-tests. The first test focused on the comparison of four calcification fluids under dynamic contact with n=12 commercial bovine pericardium patches. The second one focused on the validation of the most appropriate fluid by analyzing the calcification potential of pericardium vs. polyurethane. The patches were mounted in separate test compartments and treated simultaneously with the respective fluids at an accelerated test frequency. Calcification propensity and progression were detected macroscopically and microscopically. Structural analyses of all deposits indicated hydroxyapatite by X-ray powder diffraction, which is also most commonly observed in vivo.
