Pengaruh Iradiasi Ultraviolet Terhadap Multiplikasi Tunas Aksiler Dan Kadar Klorofil Anyelir (Dianthus Caryophyllus L.)

Ultraviolet (UV) is one of the lights spectrum that causes plant cell to damage. The use of ultraviolet irradiation in combination with tissue culture techniques has not been widely used in somaclonal variation method for carnation breeding, whereas the source of ultraviolet irradiation is more easily obtained compared to other sources of irradiation such as gamma rays, x-rays and neutron rays. The purpose of this study was to determine effect of ultraviolet irradiation on the multiplication of axillary shoot in carnation. Explants of internode stem of carnation were grown in multiplication medium Murashige Skoog (MS) consisted of 10-7 M NAA and 5.10-6 M BAP. After four times subculture, the culture bottles were exposed to ultraviolet light C with some variation of irradiation time in combination with storage in light or dark. The results showed that ultraviolet light can reduce the number of shoots formed, shoot length and chlorophyll content of carnation. Based on the results obtained, ultraviolet radiation affected the organs of plants that were formed, but did not cause meristem activity to a standstil

Evaluasi Plasma Nutfah Padi Gogo Berdasarkan Karakter Kuantitatif Perakaran Tanaman

Produktivitas padi gogo umumnya lebih rendah dibanding dengan padi sawah disebabkan oleh sifat fisik dan terbatasnya air dalam tanah serta karakteristik perakaran tanaman. Varietas padi gogo yang adaptif pada lingkungan lahan marginal dapat diperoleh melalui pemuliaan tanaman. Tujuan penelitian ini adalah mengevaluasi sistem perakaran plasma nutfah padi gogo melalui kemampuan perakarannya menembus lapisan keras dan untuk mengukur perakaran yang diduga berkaitan dengan adaptabilitasnya terhadap lingkungan kekeringan dan kepadatan tanah. Penelitian dilakukan di rumah kaca BB Biogen Bogor pada bulan Juli–Agustus 2015. Benih plasma nutfah 100 aksesi (varietas lokal) yang berasal dari provinsi Sumatra Utara, Sumatra Selatan, Sulawesi Utara, Jambi, Kalimantan Tengah, Kalimantan Timur, NTT, Jawa Tengah, Jawa Timur, Jawa Barat, DIY, dan Banten ditanam pada pot dengan bagian dasar dilapisi dengan kombinasi campuran 60% parafin dan 40% vaselin yang setara dengan kekerasan 12 bar. Hasil penelitian menunjukkan pengelompokan plasma nutfah 100 varietas padi gogo dapat dikelompokkan berdasarkan varietas yang karakteristiknya jauh berbeda dengan yang lain, yaitu varietas Si Gambiri Etek asal Sumatra Utara, varietas Cikapundeng asal Banten, dan varietas Ketan Kasumba B asal Banten. Plasma nutfah yang memiliki karakteristik perakaran baik (bobot akar dan rasio akar tajuk yang tinggi) dapat digunakan sebagai tetua dalam program pemuliaan tanaman

MICALs in control of the cytoskeleton, exocytosis, and cell death

MICALs form an evolutionary conserved family of multidomain signal transduction proteins characterized by a flavoprotein monooxygenase domain. MICALs are being implicated in the regulation of an increasing number of molecular and cellular processes including cytoskeletal dynamics and intracellular trafficking. Intriguingly, some of these effects are dependent on the MICAL monooxygenase enzyme and redox signaling, while other functions rely on other parts of the MICAL protein. Recent breakthroughs in our understanding of MICAL signaling identify the ability of MICALs to bind and directly modify the actin cytoskeleton, link MICALs to the docking and fusion of exocytotic vesicles, and uncover MICALs as anti-apoptotic proteins. These discoveries could lead to therapeutic advances in neural regeneration, cancer, and other diseases

PANC Study (Pancreatitis: A National Cohort Study): national cohort study examining the first 30 days from presentation of acute pancreatitis in the UK

Abstract Background Acute pancreatitis is a common, yet complex, emergency surgical presentation. Multiple guidelines exist and management can vary significantly. The aim of this first UK, multicentre, prospective cohort study was to assess the variation in management of acute pancreatitis to guide resource planning and optimize treatment. Methods All patients aged greater than or equal to 18 years presenting with acute pancreatitis, as per the Atlanta criteria, from March to April 2021 were eligible for inclusion and followed up for 30 days. Anonymized data were uploaded to a secure electronic database in line with local governance approvals. Results A total of 113 hospitals contributed data on 2580 patients, with an equal sex distribution and a mean age of 57 years. The aetiology was gallstones in 50.6 per cent, with idiopathic the next most common (22.4 per cent). In addition to the 7.6 per cent with a diagnosis of chronic pancreatitis, 20.1 per cent of patients had a previous episode of acute pancreatitis. One in 20 patients were classed as having severe pancreatitis, as per the Atlanta criteria. The overall mortality rate was 2.3 per cent at 30 days, but rose to one in three in the severe group. Predictors of death included male sex, increased age, and frailty; previous acute pancreatitis and gallstones as aetiologies were protective. Smoking status and body mass index did not affect death. Conclusion Most patients presenting with acute pancreatitis have a mild, self-limiting disease. Rates of patients with idiopathic pancreatitis are high. Recurrent attacks of pancreatitis are common, but are likely to have reduced risk of death on subsequent admissions. </jats:sec

Demographic Factors and Saving Behaviour: It’s Relevance in Financial Planning for Retirement

Life expectancy, in India, was 41 years in 1960, which stands 69.4 years in the year 2018, (World Bank, 2020). This improvement in the life expectancy is due to enhanced standard of living and improved healthcare system in India. India is a young nation with 28.34 years as a median age and more than 60 per cent of the population is in the working age group. Favourable saving and investment practices followed by this young population would lead to personal wealth creation and there would not be financial strain after retirement. RBI report on household finance revealed that 77 per cent of the population did not save for retirement. It is important to understand the saving and investment practices followed by this young population. The saving and investment practices are influenced by many demographic variables (May &amp; Sterne, 2018). Demographic variables such as age, gender, income, education, family size to name a few, influence the earning capability, amount available for saving, understanding of various financial products available for investment and making financial plan for life after retirement. The present study has probed into relevance of demographic factors in financial planning for retirement. The study has considered predictor variables, namely age, gender, education, profession, size of the family, total earning members in the family, frequency of saving and advice for saving. The study is conducted in the Quilon City, Kerala. For the study primary data is collected using structured questionnaire. Google form was the medium to collect the data. Binary logistic regression is used to analyse influence of afore mentioned variables on individual’s act to take decision to make financial plan for retirement. The study revealed that age, profession, number of earning members in the family, frequency of saving and advice for saving has significant impact on individual’s initiative to plan for retirement.

Stress Perceptions of Working Adult Pakistanis and Americans

Workplace stress can impact personal stress and these are of concern for all adults in every economy. This practical paper compares the perceptions of 231 working adults in Pakistan with 288 Americans. While a moderate level of stress was found among these respondents and in the U.S., higher stress levels were discovered among Pakistanis. While older respondents and males did have higher stress scores, no statistically significant differences were linked to age or gender. However, statistically significant differences were found between those who had for government and those who did not work in the public sector. Pakistani respondents without a college degree had higher stress scores than those with higher degree. Suggestions and recommendation for stress reduction and stress management are provide
