Free Radical Scavenging Activity of Ethanolic Extracts from Herbs and Spices Commercialized in Brazil

Ethanolic extracts from 23 different dried herbs and spices commercialized in Brazil were investigated for their free radical scavenging properties using the stable free radicals 2,2'-diphenyl-β-picrylhydrazyl (DPPH•) and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS•+), and Trolox as reference (TEAC) for both radicals. The kinetic curves for both radicals showed to follow the first order kinetics model and the decay rate constant (kobs) was calculated. For all the samples, the two methods showed a good linear TEAC correlation, indicating that the average reactivity of the compounds present in the ethanolic extracts was similar. Sage and rosemary extracts showed the highest free radical scavenging capacities, while onion showed negligible activity and colorifico, one of the most consumed spices in Brazil, showed low ABTS•+ scavenging activity. Three distinct situations were found for the extracts concerning the DPPH• scavenging capacities: (1) extracts, like rosemary and laurel, that presented the same efficient concentrations (EC50 ) but differed in the TEAC values and velocities of action (kobs), (2) extracts, such as garlic and basil, that showed similar EC50 and TEAC values, but different kobs values and (3) extracts that reacted at the same velocities but completely differed in the free radical scavenging capacities, like black pepper, savory, nutmeg, rosemary and sage. Similar considerations could be done for the ABTS•+ results. For the first time the ABTS•+ scavenging activity for allspice, basil, cardamom, chives, colorifico, cumin, dill, laurel, marjoram, parsley and tarragon was reported.
AN OVERVIEW OF ANTIDIABETIC PROFILE OF MANGROVE PLANTS

The present article is a review that gives a general idea of diabetic mellitus, its treatment using mangrove plants as herbal drugs. Despite considerable progress in the treatment of diabetes by oral hypoglycemic agents, search for newer drugs continues because the existing synthetic drugs have several limitations. The herbal mangrove plants with antidiabetic activity are yet to be commercially formulated as modern medicines, even though the drugs have been acclaimed for their therapeutic properties in the traditional systems of medicine. This paper highlighted various mangrove plants available in Indian coastal areas and its antidiabetic activities.
On the recovery of peak ground velocity and peak ground displacement from strong-motion records

Peak ground velocity (PGV) and peak ground displacement (PGD) are important strong ground motion parameters for correlating with damage caused by an earthquake, for analysis of existing structures and for the design of new structures. Unlike peak ground acceleration, PGV and PGD are greatly affected by the accelerogram processing technique used. PGD is composed of two parts: the transient displacement which should equal zero at the end of the record and the displacement due to a permanent movement of the recording station, caused by fault slip or foundation failure for example. In the near field of large earthquakes permanent displacements can be much larger than transient displacements; however they are not recovered by standard processing methods based on filtering. Filtering of strong-motion records leads to underestimating PGV and PGD for large earthquakes which can have an important effect on work that employs these parameters.
Chinese Midlife Women's Perceptions and Attitudes About Menopause

ObjectiveThe purpose of this research was to discover and describe the meaning of and attitudes toward menopause in midlife Chinese women in Taiwan. How these women learned about menopause was also explored. DesignQuestionnaires were distributed to a convenience sample of 208 Chinese women aged 35 to 55 living in Taiwan; 168 responded. Qualitative data were analyzed using content analysis. Percentage and chi-square were used to examine the quantitative data. ResultsThe findings revealed that 154 (91.7%) women perceived menopause as a natural phenomenon. No statistically significant differences in attitude toward menopause were found between women grouped by different menopausal levels, by use or not use of hormones, or by religious preference. Some women described menopause as, “no longer young, getting old. ” Others described menopause as, “wisdom and maturation,” “a symbol of achievement,” and “a time to start enjoying life. ” Sixty-eight (40.5%) of the sample indicated they obtained menopausal information from friends and printed materials such as books, newspapers, and magazines. ConclusionsStudy findings indicate that Chinese women in Taiwan perceive menopause in a positive and holistic way. Culturally sensitized Western practitioners can utilize this study's findings to more appropriately individualize care for Chinese midlife women.
LAMA2-Related Dystrophies: Clinical Phenotypes, Disease Biomarkers, and Clinical Trial Readiness

Mutations in the LAMA2 gene affect the production of the α2 subunit of laminin-211 (= merosin) and result in either partial or complete laminin-211 deficiency. Complete merosin deficiency is typically associated with a more severe congenital muscular dystrophy (CMD), clinically manifested by hypotonia and weakness at birth, the development of contractures of large joints, and progressive respiratory involvement. Muscle atrophy and severe weakness typically prevent independent ambulation. Partial merosin deficiency is mostly manifested by later onset limb-girdle weakness and joint contractures so that independent ambulation is typically achieved. Collectively, complete and partial merosin deficiency is referred to as LAMA2-related dystrophies (LAMA2-RDs) and represents one of the most common forms of congenital muscular dystrophies worldwide. LAMA2-RDs are classically characterized by both central and peripheral nervous system involvement with abnormal appearing white matter (WM) on brain MRI and dystrophic appearing muscle on muscle biopsy as well as creatine kinase (CK) levels commonly elevated to >1,000 IU/L. Next-generation sequencing (NGS) has greatly improved diagnostic abilities for LAMA2-RD, and the majority of patients with merosin deficiency carry recessive pathogenic variants in the LAMA2 gene. The existence of multiple animal models for LAMA2-RDs has helped to advance our understanding of laminin-211 and has been instrumental in preclinical research progress and translation to clinical trials. The first clinical trial for the LAMA2-RDs was a phase 1 pharmacokinetic and safety study of the anti-apoptotic compound omigapil, based on preclinical studies performed in the dyW/dyW and dy2J/dy2J mouse models. This phase 1 study enabled the collection of pulmonary and motor outcome measures and also provided the opportunity for investigating exploratory outcome measures including muscle ultrasound, muscle MRI and serum, and urine biomarker collection. Natural history studies, including a five-year prospective natural history and comparative outcome measures study in patients with LAMA2-RD, have helped to better delineate the natural history and identify viable outcome measures. Plans for further clinical trials for LAMA2-RDs are presently in progress, highlighting the necessity of identifying adequate, disease-relevant biomarkers, capable of reflecting potential therapeutic changes, in addition to refining the clinical outcome measures and time-to-event trajectory analysis of affected patients.
SARS-CoV-2 Dissemination Through Peripheral Nerves Explains Multiple Organ Injury

Coronavirus disease (CoVID-19), caused by recently identified severe acute respiratory distress syndrome coronavirus 2 (SARS-CoV-2), is characterized by inconsistent clinical presentations. While many infected individuals remain asymptomatic or show mild respiratory symptoms, others develop severe pneumonia or even respiratory distress syndrome. SARS-CoV-2 is reported to be able to infect the lungs, the intestines, blood vessels, the bile ducts, the conjunctiva, macrophages, T lymphocytes, the heart, liver, kidneys, and brain. More than a third of cases displayed neurological involvement, and many severely ill patients developed multiple organ infection and injury. However, less than 1% of patients had a detectable level of SARS-CoV-2 in the blood, raising a question of how the virus spreads throughout the body. We propose that nerve terminals in the orofacial mucosa, eyes, and olfactory neuroepithelium act as entry points for the brain invasion, allowing SARS-CoV-2 to infect the brainstem. By exploiting the subcellular membrane compartments of infected cells, a feature common to all coronaviruses, SARS-CoV-2 is capable to disseminate from the brain to periphery via vesicular axonal transport and passive diffusion through axonal endoplasmic reticula, causing multiple organ injury independently of an underlying respiratory infection. The proposed model clarifies a wide range of clinically observed phenomena in CoVID-19 patients, such as neurological symptoms unassociated with lung pathology, protracted presence of the virus in samples obtained from recovered patients, exaggerated immune response, and multiple organ failure in severe cases with variable course and dynamics of the disease. We believe that this model can provide novel insights into CoVID-19 and its long-term sequelae, and establish a framework for further research.
Gut-Brain Axis in the Early Postnatal Years of Life: A Developmental Perspective

Emerging evidence suggests that alterations in the development of the gastrointestinal (GI) tract during the early postnatal period can influence brain development and vice-versa. It is increasingly recognized that communication between the GI tract and brain is mainly driven by neural, endocrine, immune, and metabolic mediators, collectively called the gut-brain axis (GBA). Changes in the GBA mediators occur in response to the developmental changes in the body during this period. This review provides an overview of major developmental events in the GI tract and brain in the early postnatal period and their parallel developmental trajectories under physiological conditions. Current knowledge of GBA mediators in context to brain function and behavioral outcomes and their synthesis and metabolism (site, timing, etc.) is discussed. This review also presents hypotheses on the role of the GBA mediators in response to the parallel development of the GI tract and brain in infants.
Semantic network abnormality predicts rate of cognitive decline in patients with probable Alzheimer's disease

Abstract The present study examined the relationship between rate of cognitive decline in patients with Alzheimer's disease (AD) and the integrity of the network of associations that comprise their semantic knowledge. The integrity of the semantic network of 12 AD patients was determined by comparing their networks to a standard normal control network derived with Pathfinder analysis, a multidimensional graphic analysis technique. A simple linear regression analysis, comparing the degree of semantic network deterioration with rate of cognitive decline as measured by the difference between the Dementia Rating Scale (DRS) scores obtained at the time of the testing of semantic knowledge (Year 1) and one year later (Year 2), was highly significant (r2 = .84; p < .001). These results suggest that a sensitive measure of the structural deterioration of semantic knowledge may be useful for predicting the rate of progression of cognitive changes in patients with AD.

Discrimination in the Labour Market: The Curse of Competition between Workers

In an experiment we identify a crucial factor that determines whether employers engage in statistical discrimination of ex-ante equal groups. In the standard no-competition setup of Coate and Loury (1993), we do not nd systematic evidence for statistical discrimination. When we introduce competition between workers of dierent groups for the same job, the non-discrimination equilibrium ceases to be stable. In line with this theoretical observation, we nd systematic discrimination in the experimental treatment with competition. Nevertheless, a substantial minority of the employers refuses to discriminate even when it is in their best interest to do so.
Dual Targeting to Overcome Current Challenges in Multiple Myeloma CAR T-Cell Treatment

In the era of highly promising novel targeted-immunotherapy strategies for multiple myeloma (MM), the first series of clinical trials with CAR T-cells targeting the plasma cell-specific B-cell maturation antigen (BCMA) have shown excellent response rates. In the long-term, however, MM appears to escape the therapy likely due to initial low and heterogeneous expression or downregulation of BCMA expression. Several other molecules targeted by CAR T-cells in MM are expressed at high levels on MM cells, but many of these attractive targets are also expressed on various, sometimes vital non-malignant cells, posing major risks for on-target, off-tumor side effects. CAR T-cell therapy for MM therefore faces two urgent challenges: (i) improving the efficacy of BCMA CAR T-cells and (ii) establishing a MM-selectivity even when CAR T-cells are directed against not entirely MM-specific target antigens. In this review, we will outline the current attempts to tackle these challenges, with a specific focus on how dual CAR targeting might be applied to tackle both issues.
Managing anthelmintic resistance: Is it feasible in New Zealand to delay the emergence of resistance to a new anthelmintic class?

Abstract The recent registration in New Zealand of the first new class of broad-spectrum anthelmintic, for use against nematode parasites of ruminants, in nearly three decades has raised the possibility that parasite management practices could be improved to minimise the emergence of resistance to the new drug. A review of knowledge pertaining to the selection of anthelmintic resistance in nematode parasites of sheep highlights a number of management practices which could be altered to achieve this. A number of previously common practices such as whole-flock treatment of adult ewes around lambing, and treatment of lambs as they are moved onto pastures with low parasite contamination have been clearly identified as high risk for selecting resistant parasites. Once high-risk practices have been identified steps can be taken to either eliminate their use or mitigate the associated risk. Much of the focus on the management of resistance around the world is on the retention of susceptible genotypes in refugia. While approaches to retaining unselected parasites are likely to vary around the world, empirical studies indicate that the practice is likely to be effective at slowing the development of resistance. The challenge for farmers and advisors will be to strike a balance between retaining sufficient susceptible para-sites to usefully delay the development of resistance while not unduly compromising animal performance and farm profitability. The merits of combining different classes of anthelmintic in order to slow the development of resistance remains somewhat contentious in some countries. However, the attributes of oral anthelmintics are such that they seem likely to meet most, if not all, of the criteria for combinations to be highly effective at slowing the build-up of resistance in nematode parasites. It is evident that considerable progress has been made in understanding the factors involved in selecting anthelmintic-resistant nematodes since the last broad-spectrum anthelmintic class was released in the early 1980s. Therefore, it should be possible to manage a new class of anthelmintic in such a way as to significantly extend its effective life. The challenge is likely to be in convincing farmers of the merits of adopting such pro-active strategies.
Condom use and partner characteristics among young adult males in urban Ghana, aged 15–24

Abstract Addressing male sexual behavior and condom use is a high priority for adolescent health programs. Using the 1997 Ghana Psychographic Survey, the aim of this study is to explore the factors related to current, partner‐specific condom use, by Ghanaian males aged 15–24 years. A multivariate regression analysis reveals an independent association between psychographic attitudes, peer network characteristics, sexual partner characteristics, and some level of condom use with a nominated sexual partner. The most important predictor for both condom use consistently as well as condom use at least sometimes was respondents’ knowing someone who died as a result of AIDS. This finding suggests that future interventions should aim to personalize the risk of HIV/STIs, promote condom use with a range of partner types, and educate youth about the importance of consistent use.
Plasmodium yoelii inhibitor of cysteine proteases is exported to exomembrane structures and interacts with yoelipain‐2 during asexual blood‐stage development

Plasmodium falciparum (Pf) blood stages express falstatin, an inhibitor of cysteine proteases (ICP), which is implicated in regulating proteolysis during red blood cell infection. Recent data using the Plasmodium berghei rodent malaria model suggested an additional role for ICP in the infection of hepatocytes by sporozoites and during liver‐stage development. Here we further characterize the role of ICP in vivo during infection with Plasmodium yoelii (Py) and Pf. We found that Py‐ICP was refractory to targeted gene deletion indicating an essential function during asexual blood‐stage replication, but significant downregulation of ICP using a regulated system did not impact blood‐stage growth. Py‐ICP localized to vesicles within the asexual blood‐stage parasite cytoplasm, as well as the parasitophorous vacuole, and was exported to dynamic exomembrane structures in the infected RBC. In sporozoites, expression was observed in rhoptries, in addition to intracellular vesicles distinct from TRAP containing micronemes. During liver‐stage development, Py‐ICP was confined to the parasite compartment until the final phase of liver‐stage development when, after parasitophorous vacuolemembrane breakdown, it was released into the infected hepatocyte. Finally, we identified the cysteine protease yoelipain‐2 as a binding partner of Py‐ICP during blood‐stage infection. These data show that ICP may be important in regulating proteolytic processes during blood‐stage development, and is likely playing a role in liver stage‐hepatocyte interactions at the time of exoerythrocytic merozoite release.
Prosodic Variation and Segmental Reduction and Their Roles in Cuing Turn Transition in Swedish

Prosody has often been identified alongside syntax as a cue to turn hold or turn transition in conversational interaction. However, evidence for which prosodic cues are most relevant, and how strong those cues are, has been somewhat scattered. The current study addresses prosodic cues to turn transition in Swedish. A perception study looking closely at turn changes and holds in cases where the syntax does not lead inevitably to a particular outcome shows that Swedish listeners are sensitive to duration variations, even in the very short space of the final unstressed syllable of a turn, and that they may use pitch cues to a lesser extent. An investigation of production data indicates that duration, and to some extent segmental reduction, demonstrate consistent variation in relation to the types of turn boundaries they accompany, while fundamental frequency and glottalization do not. Taken together, these data suggest that duration may be the primary cue to turn transition in Swedish conversation, rather than fundamental frequency, as some other studies have suggested.
Evaluation of the End Effect Impact on the Torsion Test for Determining the Shear Modulus of a Timber Beam through a Photogrammetry Approach

The timber beam end effect in the torsion test is evaluated using binocular stereo vision system. It is recommended by BS EN 408:2010+A1:2012 to exclude a distance of two to three times of cross-sectional thickness (b) from ends to avoid the end effect; whereas, this study indicates that this distance is not sufficiently far enough to remove this effect in slender cross-sections. The shear modulus of six timber beams with different aspect ratios is determined at the various angles and cross-sections. The result of this experiment shows that the end affected span of each specimen varies depending on their aspect ratios. It is concluded that by increasing the aspect ratio this span will increase. However, by increasing the distance from the ends to the values greater than 6b, the shear modulus trend becomes constant and end effect will be negligible. Moreover, it is concluded that end affected span is preferred to be depth-dependent rather than thickness-dependant.
Regional Growth in Medicare Spending, 1992-2010.

OBJECTIVE To determine if regions with high Medicare expenditures in a given setting remain high cost over time. DATA SOURCES/STUDY SETTING One hundred percent of national Medicare Parts A and B fee-for-service beneficiary claims data and enrollment for 1992-2010. STUDY DESIGN Patients are classified into regions. Claims are price-standardized. Risk adjustment is performed at the beneficiary level using the CMS Hierarchical Condition Categories model. Correlation analyses are conducted. DATA COLLECTION/EXTRACTION METHODS The data were obtained through a contract with CMS for a study performed for the Institute of Medicine. PRINCIPAL FINDINGS High-cost regions in 1992 are likely to remain high cost in 2010. Stability in regional spending is highest in the home health, inpatient hospital, and outpatient hospital settings over this time period. Despite the persistence of a region's relative spending over time, a region's spending levels in all settings except home health tend to regress toward the mean. CONCLUSIONS Relatively high-cost regions tend to remain so over long periods of time, even after controlling for patient health status and geographic price variation, suggesting that the observed effect reflects real differences in practice patterns.
Histopathology, Electrodiagnostic Testing, and Magnetic Resonance Imaging Show Significant Peripheral and Central Nervous System Myelin Abnormalities in the Cat Model of Alpha‐Mannosidosis

Alpha-mannosidosis is a disease caused by the deficient activity of alpha-mannosidase, a lysosomal hydrolase involved in the degradation of glycoproteins. The disease is characterized by the accumulation of mannose-rich oligosaccharides within lysosomes. The purpose of this study was to characterize the peripheral nervous system (PNS) and central nervous system (CNS) myelin abnormalities in cats from a breeding colony with a uniform mutation in the gene encoding alpha-mannosidase. Three affected cats and 3 normal cats from 2 litters were examined weekly from 4 to 18 wk of age. Progressively worsening neurological signs developed in affected cats that included tremors, loss of balance, and nystagmus. In the PNS, affected cats showed slow motor nerve conduction velocity and increased F-wave latency. Single nerve fiber teasing revealed significant demyelination/remyelination in affected cats. Mean G-ratios of nerves showed a significant increase in affected cats compared to normal cats. Magnetic resonance imaging of the CNS revealed diffuse white matter signal abnormalities throughout the brain of affected cats. Quantitative magnetization transfer imaging showed a 8%–16% decrease in the magnetization transfer ratio in brain white matter of affected cats compared to normal cats, consistent with myelin abnormalities. Histology confirmed myelin loss throughout the cerebrum and cerebellum. Thus, histology, electrodiagnostic testing, and magnetic resonance imaging identified significant myelination abnormalities in both the PNS and CNS that have not been described previously in alpha-mannosidosis.
