Role of Plant Volatile to Diaphorina citri on Feeding and Oviposition Behaviour

Citrus production in Indonesia and in the world is suffered from disease of citrus vein phloem degeneration (CVPD. It was vectored by psylids (Diaphorina citri). The psylids used citrus plant volatiles as cues for finding their host plants for feeding and laying eggs. Extract of guava leaves was a prospective control material for declaining population of psyllid. Investigation by research was conducted to determine the effect of CVPD symptomatic citrus plants in attracting psylids gravid female for staying and laying eggs, and also to determine the repellency ability of guava shoots to adult psyllids. Citrus buds of healthy plants and CVPD symptomatic plants were exposed to ten gravid female and the number of psylids stay and the number of eggs per bud was recorded. Y-tube olfactometer was used to determine repellent effect of upper shoot, middle shoot, and bottom shoot of guava leave to ten adult psyllids. The result shows that CVPD symptomatic plants was more attractive for laying eggs, eventhough the number of eggs was higher on healthy plants. Repellence effect to psyllids adult was identified in guava leave extracts. The increase of leaf age would decrease the effect. It was suggested that repellent properties was highest youngest leaf or upper shoots of guava.

Time for Space and the Stability of Prospective Control: Reaching-to-Grasp Gibson

Gibson formulated an approach to goal-directed behavior using prospective information in the context of visually guided locomotion and manual behavior. The former was Gibson's paradigm case, but it is the rapidity of targeted reaching that has provided the special challenge for stable control. Recent treatments of visually guided reaching assume that internal forward models are required to generate stable behavior given delays caused by neural transmission times. Internal models are representations of the sort eschewed by Gibson in favor of prospective information. Reaching is usually described as guided using relative distances of hand and target, but prospective information is usually temporal rather than spatial. We describe proportional rate control models that incorporate time dimensioned prospective information and show they remain stable in the face of delays. The use of time-dimensioned prospective information removes the need for internal models for stable behavior despite neural transmission delays and allows Gibson's approach to prevail.

A Comparative Study of Efficacy and Tolerability of Solifenacin and Mirabegron, for the Treatment of Overactive Bladder - A Randomized Prospective Control Study

BACKGROUND Overactive bladder (OAB) is a chronic, age-related disorder seen in 11 % of patients. Symptoms consist of urinary urgency, with or without urinary incontinence, usually with frequency or nocturia. The objective of the present study was to compare the efficacy and side effects of mirabegron and solifenacin as primary therapies in patients with overactive bladder. METHODS This was a prospective interventional study. 100 patients aged between 18 years and 50 years with overactive bladder were included and were assigned into two treatment groups of solifenacin 5 mg or mirabegron 50 mg. They were asked to record the number of micturitions in a day, urgency episodes, incontinence episodes and volume of each micturition. All patients went through a basic workup with blood sugar to rule out diabetes, USG KUB to rule out bladder stones, and urine culture and sensitivity to rule out urinary tract infection (UTI). RESULTS 100 patients with OAB were selected for the study and divided into equal groups, 50 receiving 5 mg solifenacin and 50 receiving 50 mg mirabegron. Both groups increased the mean micturition volume but mirabegron was more effective in increasing the mean micturition in patients with OAB. Both drugs were well tolerated. There was a significant increase in mean micturition volume in mirabegron 50 mg group (by 20.7 + / - 2.2 mL), P < 0.001 whereas in solifenacin group micturition volume was increased to 22.2 + / -0.97 ml). The most common side-effect in the mirabegron group was hypertension and the most common side effect in the solifenacin group was dry mouth. CONCLUSIONS Both mirabegron and solifenacin were effective in controlling the frequency of micturition, decreasing urgency and incontinence episodes and increasing the mean volume of micturition. Mirabegron was more effective than solifenacin in controlling urgency and incontinence episodes and increasing the mean volume of micturition. KEY WORDS Overactive Bladder (OAB), Micturition, Mirabegron, Solifenacin.

Financial technologies for bank financial stability management in economical turbulence conditions

The development of the global economy is characterized by an increase in turbulence and the restoration of a cyclic crisis component of development. An important driving force for the development of the economy is the financial stability of the bank, which manifests itself at all levels – from the micro level to the global economic system. The market of banking services is the most dynamic segment of the financial market, where the number of subjects and spectrum of products, the level of service and technologies is constantly changing. The priority instrument for managing the financial stability of the bank in the conditions of turbulence of the economy is a financial engineering, which is a system of synergistic functioning, pre-developed and implemented combinations and processes (namely the interaction of financial innovations, financial technologies and financial instruments) in financial management of the bank due to the release of innovation resource reserve. to ensure the financial stability of the bank. Financial innovations include financial instruments and financial technologies. Financial technologies are technologically supported by financial innovations, which can lead to new business models, programs, processes or products that have a significant impact on financial markets and institutions that provide financial services. It is proposed to manage the financial stability of the bank in the conditions of turbulence of the economy of Ukraine to introduce a process approach that is focused on improving the motivation of banking institutions and a clear distribution of their responsibilities; achievement of internal transparency for guidance, obtaining information in real time due to the development and strengthening of the system of current and prospective control; improving the quality and predictability of the results of work; providing trust of stakeholders to banking institutions and confidence in the financial stability of its functioning; minimization of expenses and reducing the terms of organization of technological cycles of banking operations. In order to ensure the financial stability of the bank on the basis of financial technologies, the state of turbulence of the economy should be taken into account, react promptly to its changes that require enhanced control.

Diagnosis of Peripheral Pulmonary Lesions with Transbronchial Lung Cryobiopsy by Guide Sheath and Radial Endobronchial Ultrasonography: A Prospective Control Study

Objective. We design a prospective control study on the utilization of transbronchial cryobiopsy guided by EBUS-GS (EBUS-GS-TBCB) to diagnose PPLs. Methods. PPLs were defined as pulmonary nodules or masses with a diameter from 10 mm to 50 mm. PPLs were randomly divided into group EBUS-GS-TBCB and transbronchial biopsy by forceps guided under EBUS-GS (EBUS-GS-TBB). Results. 28 cases were involved in group EBUS-GS-TBCB and 31 cases were in group EBUS-GS-TBB. The mean sizes of PPLs were 30.23 ± 11.10 mm in group EBUS-GS-TBCB and 28.69 ± 8.62 mm in group EBUS-GS-TBB (t = 0.600, p = 0.551 ). The diagnostic yields of EBUS-GS-TBCB and EBUS-GS-TBB were 75% and 64.52% respectively, and the difference between the two groups was not significant (χ2 value = 0.137, p = 0.711 ). If only the first specimen was taken into account, the diagnostic yields from EBUS-GS-TBCB and EBUS-GS-TBB were 64.29% (18/28 cases) and 35.48% (11/31 cases), respectively. The difference was statistically significant by Fisher’s Exact Test (χ2 value = 4.883, p = 0.038 ). The total incidence rates of bleeding were 21.43% and 6.45%, respectively, in groups EBUS-GS-TBCB and EBUS-GS-TBB. The total incidence rates of pneumothorax were 7.14% and 0, respectively, in groups EBUS-GS-TBCB and EBUS-GS-TBB. Conclusion. The diagnostic yield of EBUS-GS-TBCB was slightly higher than that of EBUS-GS-TBB for the diagnosis of PPLs. EBUS-GS-TBCB might be useful if only the first sample was taken into account.

The potential impact of Anopheles stephensi establishment on the transmission of Plasmodium falciparum in Ethiopia and prospective control measures

Anopheles stephensi, the primary urban malaria vector in Asia, was first detected in Africa during 2012 in Djibouti and was subsequently identified in Ethiopia in 2016, and later in Sudan and Somalia. In Djibouti, malaria cases have increased 30-fold from 2012 to 2019 though the impact in the wider region remains unclear. A mechanistic model of malaria transmission was used to estimate the increase in vector density required to explain the trends in malaria cases seen in Djibouti. Applying this vector density to Ethiopia, we assess the potential impact of An. stephensi establishment on Plasmodium falciparum transmission, accounting for pre-existing transmission and control interventions. We estimate that annual P. falciparum malaria cases could increase by 50% (95% CI 14-90) if no additional interventions are implemented. Substantial heterogeneity across the country is predicted and large increases in vector control interventions could be needed to prevent a major public health emergency.

Perceptions of Control Influence Feelings of Boredom

Conditions of low and high perceived control often lead to boredom, albeit for different reasons. Whereas, high perceived control may be experienced as boring because the situation lacks challenge, low perceived control may be experienced as boring because the situation precludes effective engagement. In two experiments we test this proposed quadratic relationship. In the first experiment we had participants play different versions of the children's game “rock-paper-scissors” in which they arbitrarily won (intended to maximize feelings of control) or lost (to induce feelings of low control). Despite having only dichotomous conditions, participants reported experiencing a broad range of levels of perceived control. Consistent with our predictions, boredom was highest at low and high levels of perceived control (i.e., a quadratic relation between perceived control and felt boredom). Experiment 2 tested the notion that the mere prospect of gaining control may mitigate boredom. Participants given to believe (erroneously) that they could gain control over the game of rock, paper, scissors were less bored than those who believed there was no possibility of winning at greater than chance levels. This suggests that beliefs concerning prospective control, rather than a given level of perceived control per se, may predict engagement and boredom.

Current Overviews on COVID-19 Management Strategies

The coronavirus pandemic has hit the world lately and caused acute respiratory syndrome in humans. The causative agent of the disease was soon brought to focus by scientists as SARS-CoV-2 and later called a novel coronavirus by the general public. Due to the severity and rapid spread of the disease, WHO classifies the COVID-19 pandemic as the 6th public health emergency even after taking efforts like worldwide quarantine and restrictions. Since only symptomatic treatment is available, the best way to control the spread of the virus is by taking preventive measures. Various types of antigen/antibody detection kits and diagnostic methods are available for the diagnosis of COVID-19 patients. In recent years, various phytochemicals and repurposing drugs are showing a broad range of anti-viral activities with different modes of action have been identified. Repurposing drugs such as arbidol, hydroxychloroquine, chloroquine, lopinavir, favipiravir, remdesivir, hexamethylene amiloride, and dexamethasone, tocilizumab, interferon-β, neutralizing antibodies exhibit in vitro anti-coronaviral properties by inhibiting multiple processes in the virus life cycle. Various research groups are involved in drug trials and vaccine development. Plant-based anti-viral compounds such as baicalin, calanolides, curcumin, oxymatrine, matrine, and resveratrol exhibit different modes of action against a wide range of positive/negative sense-RNA/DNA virus, and future researches need to be conducted to ascertain their role, use in managing SARS-CoV-2. Thus, this article is an attempt to review the current understanding of COVID-19 acute respiratory disease and summarize its clinical features with their prospective control and various aspects of the therapeutic approach.
