With the development of new satellite payload technology, in order to improve the utilization of system resources, research is based on software-defined network (SDN) and network function virtualization (NFV) gateway architecture. Based on this architecture, the system realizes global resource management and overall data distribution, which can solve the problem of resource allocation and maximum/minimum rate guarantee between different VNO terminals under different beams, different gateways, and different satellites. For this, a global bandwidth management method can be used which is mainly a process of management to control the traffic on a communication link. The proposed global resource management and control method can be based on the rate guarantee value of the VNO/terminal configured in the system as the basic limiting condition and reallocate the rate guarantee value limiting parameter according to the resource application status of the online terminal. The method can maximize the resource utilization of the entire satellite communication system and satisfy the resource request of the user terminal as much as possible.

Few Korean hospitals had experience in pediatric palliative care. Since the beginning of the national palliative care project, interest in pediatric palliative care has gradually increased, but the establishment of professional palliative care is still inadequate due to a lack of indicators. This study aimed to find considerations in the process of initiating palliative care services. The general and clinical characteristics of 181 patients aged less than 24 years who were registered at the pediatric palliative care center from January 2019 to August 2021 were evaluated. Life-limiting condition group 1 had the largest number of patients. The primary need for palliative care was psychological and emotional support, followed by information sharing and help in communication with the medical staff in decision-making processes. Seventy-two patients were technologically dependent, with one to four technical supports for each patient. The registration of patients with cancer increased with time, and the time from disease diagnosis to consultation for pediatric palliative care service was significantly reduced. In conclusion, before starting pediatric palliative care, it is necessary to understand the needs of patients and their families and to cooperate with medical staff.

Background: Infantile colic is characterized by prolonged periods of inconsolable, incessant crying and persistent fussing in an otherwise healthy infant. It is a self-limiting condition, but causes significant stress to mothers. AIM: To observe the role of Lactobacillus reuteriDSM 17938 in reducing crying time in colicky infants in routine clinical practice. Methods: This was a prospective observational multicentric clinic-based study. Each practitioner included approximately 30 infants < 5 months of age with infantile colic who were prescribed L. reuteri DSM 17938 for a period of 21 days. There were four physical consultations and two telephonic consultations. The parents were given a daily diary to record the duration of crying and fussing episodes and a questionnaire was administered during the consultations. Results: A total of 120 infants with a mean age of 56.9 ± 34.2 days were included in this 28-day study. The mean crying time as reported by the parents in the subject diary reduced from 248.2 ± 101.2 min, 95% CI: 229.45, 266.94 at baseline to 45.6 ± 79.1 min 95% CI: 31.02, 60.31 at study end (P < 0.01). The clinical response (defined as reduction of 50% in crying time) was observed in 85% of subjects at study end. The fussiness and parental perception of colic recorded during the consultations were reduced by 66% and 72%, respectively, at study end. The maternal depression scores were reduced to 63% at study end. Conclusion: L. reuteri DSM 17938 was associated with a significant reduction in crying time in colicky infants, and showed improvement in maternal depression.

Drought is the most prevalent unfavorable condition that impairs plant growth and development by altering morphological, physiological, and biochemical functions, thereby impeding plant biomass production. To survive the adverse effects, water limiting condition triggers a sophisticated adjustment mechanism orchestrated mainly by hormones that directly protect plants via the stimulation of several signaling cascades. Predominantly, water deficit signals cause the increase in the level of endogenous ABA, which elicits signaling pathways involving transcription factors that enhance resistance mechanisms to combat drought-stimulated damage in plants. These responses mainly include stomatal closure, seed dormancy, cuticular wax deposition, leaf senescence, and alteration of the shoot and root growth. Unraveling how plants adjust to drought could provide valuable information, and a comprehensive understanding of the resistance mechanisms will help researchers design ways to improve crop performance under water limiting conditions. This review deals with the past and recent updates of ABA-mediated molecular mechanisms that plants can implement to cope with the challenges of drought stress.

Acne is derived from the Greek word “acme” which means “prime of life”. It is mostly considered to be benign and self-limiting condition but if it is ignored than it can progress to lifetime presence and scaring of the skin. Almost 85% of adolescence are affected by acne and from here males are at higher ration that female due to testosterone level that causes increase size in sebaceous gland which in turn causes more production of sebum (oil production). Women are affected more during adulthood due to imbalance of premenstrual hormones and over use of oil based cosmetics. There are many different factors that contribute to acne formation and it has many different forms. Herbal medication are considered safer than allopathic medicines because allopathic medicines are associated with various side effects such as like contact allergy, local irritation, scaling, photosensitivity, itching, redness, skin peeling, necrosis of the skin etc. In this study there are 3 herbal plants were used to prepare cream formulation that were used to investigate the anti-acne property. The aim of this research work was to develop formulations and to perform its evaluation as an herbal anti-acne cream. The objective of this study was to focus on the ant-acne or anti-bacterial effect of the formulated polyherbal cream containing three plants, Thyme, Aloe Vera and Basil. The results showed that the formulation 10 showed potential anti-acne property had that twice more concentration of aloe Vera than basil and thyme.

Abstract Water productivity is a major challenge in all agricultural regions and despite the use of pressurized irrigation system, it has not increased as expected in Iran. In addition, in spite of water shortage in Iran, gardeners because of lack of knowledge in economic consequences do not welcome deficit irrigation and irrigation scheduling. To this end, optimization of irrigation water depth in an orange orchard was conducted for two irrigation scheduling methods (with and without 4 days irrigation frequency) under water and land limitations conditions by mathematical analysis of production and cost functions. Then, their effect on the net income by changing in water and fruit price was assessed. Production and cost functions were developed based on two scenarios of applied water including only irrigation water depth and irrigation water depth plus rainfall. According to results, when water is limiting, by using the optimum water depth (Ww), 26% of irrigation water use can be saved that causes only 3–4% decrease in the net income per unit of land and 16% increase in the net income per unit of irrigation water. In addition, when water limiting is serious, using 46% deficit irrigation (Wew) is more useful and resultes the highest water productivity, even though it causes 14–17% decrease in the net income per unit of land. However in water limiting condition, if land is not limiting, using Wew causes the maximum net income per unit of land even 50–60% more than full irrigation. Moreover, using the optimum water depths in water limitation conditions (Ww and Wew) increases the water productivity 26–47% relative to full irrigation. On the other side, the net income and the amount of optimum water depths are not sensitive to the price of water at the present value of water. However, they are highly sensitive to the price of fruit. Furthermore, having an irrigation schedule causes 27% increase in the net income per unit of land. According to positive effects of deficit irrigation and irrigation scheduling on the water productivity and the income, they are highly recommended for addressing water scarcity in Iran.

Background: Palliative care improves the health of children with a life-limiting condition and appears to draw implicitly on concepts shared with a model of health promotion. However, to date there has been no scrutiny about how this relationship may shape understanding about children's palliative care. Aim: To explore the influence of health promoting concepts on children's palliative care models, policies and guidelines. Data sources: Health and social care databases were searched for policies, models and guidelines published between 2000–2018. Additional searches of professional national and international healthcare websites, children's palliative care charities and UK and Ireland government websites were conducted. Methods: A best fit framework synthesis was used. Findings: A total of 55 policies and guidelines were reviewed for the framework synthesis. Eight themes were generated: (1) health promoting children's palliative care policy and guidelines; (2) planning ahead; (3) creating a supportive environment; (4) enabling coping and independence; (5) reorienting children's palliative care sectors; (6) the lengthening trajectory of need for support; (7) strengthening community engagement in children's palliative care; and (8) quality of life and value-based ideologies. Conclusion: The best fit framework synthesis confirmed a conceptual relationship between children's palliative care and health promotion. This is captured in a new model that will extend professionals' understanding.

Summary There is emerging evidence of an association between COVID-19 vaccination and subacute thyroiditis. We present the case of a 42-year-old female healthcare worker who was diagnosed with subacute thyroiditis 4 days after receiving her second dose of Pfizer-BioNTech vaccine. Her clinical course followed the classical pattern for thyroiditis with spontaneous return to euthyroidism at 6 months post-presentation. The autoimmune/inflammatory syndrome induced by adjuvants has been implicated as a cause of autoimmune conditions post-vaccination and is a potential mechanism for subacute thyroiditis in our case. Learning points Subacute thyroiditis should be considered in all patients who receive any kind of vaccine for COVID-19 and subsequently develop symptoms or signs of hyperthyroidism or neck pain. Subacute thyroiditis is a self-limiting condition, and recognising it is important as no specific thyroid treatment (antithyroid drugs or thyroid hormone replacement) is necessary for most patients. The autoimmune/inflammatory syndrome induced by adjuvants may be an under-recognised cause of endocrinopathies and should particularly be considered post-vaccination.
