Ditylenchus Destructor

There are presented data about morpho-physiological changes, as well as physiologico biochemicals, which appear in the tissue of potato tubers infested with Ditylenchus destructor (phases 2, 3 ditylenchose). The obtained data confirms that, D. destructor in the nutrition process eliminates in parallel celulosolitic and pectolytic enzymes, which cause complete maceration of the pectocellulosic membranes of the infected potato cell, as well as the parenchymal cortical tissue in which predominantly cellulose and pectic substances , dominating being cellulose. The results of the biochemical analyzes revealed that, at this stage in the parasite tissue there is a diminishing of the dry mass quantity, and the increase of the quantity of water. It is important to mention that in the plasmalemma mechanically traumatized by the nematode stiletto, the main intracellular inclusions of the potato tuber - the starch granules - were kept without change. Subsequently, when plasmalemma is destroyed, the granules diffuse into the nematode suspension.

Stress And Health

Abstract. Stress-related stimuli may be presented outside of awareness and may ultimately influence health by causing repetitive increases in physiological parameters, such as blood pressure (BP). In this study, we aimed to corroborate previous studies that demonstrated BP effects of subliminally presented stress-related stimuli. This would add evidence to the hypothesis that unconscious manifestations of stress can affect somatic health. Additionally, we suggest that these findings may be extended by measuring affective changes relating to these physiological changes, using measures for self-reported and implicit positive and negative affectivity. Using a repeated measures between-subject design, we presented either the prime word “angry” ( n = 26) or “relax” ( n = 28) subliminally (17 ms) for 100 trials to a student sample and measured systolic and diastolic BP, heart rate (HR), and affect. The “angry” prime, compared to the “relax” prime, did not affect any of the outcome variables. During the priming task, a higher level of implicit negative affect (INA) was associated with a lower systolic BP and diastolic BP. No association was found with HR. Self-reported affect and implicit positive affect were not related to the cardiovascular (CV) activity. In sum, anger and relax primes elicited similar CV activity patterns, but implicit measures of affect may provide a new method to examine the relationship between (unconscious) stress and health.

Proven Efficacy

The development of pain is associated with numerous physiological mechanisms. Improper acute pain treatment significantly reduces the quality of life and leads to a number of physiological changes that adversely affect the general condition of the patient. In many cases, inadequate analgesic therapy results in the transition from acute to chronic pain. For this reason, it is extremely important to use drugs that synergistically affect various pain mechanisms. Combined preparations, including the combination of tramadol and dexketoprofen, are very effective. This combination has many advantages, including proven efficacy and tolerability, ensures better treatment adherence and is easy to administer.

ABSTRAK            Masa remaja mengalami perkembangan fisiologis, psikososial, kognitif, moral dan perkembangan seksual. Perubahan fisiologis pada masa remaja merupakan hasil aktivitas hormonal dibawah pengaruh sistem saraf pusat. Menarche pada umumnya menjadi masalah bagi remaja, hal ini terjadi karena remaja masih belum tahu tentang apa itu menstruasi dan bagaimana menanganinya, sehingga kebersihan daerah genetalia tidak terjaga dan dapat menimbulkan terjadinya keputihan (Soetjiningsih, 2007).            Penelitian ini bertujuan untuk mengetahui penatalaksanaan flour albus pada remaja putri kelas X di SMA AL-Fatimah Bojonegoro tahun 2016. Jenis penelitian ini adalah kualitatif yaitu penelitian expose facto (mengungkap fakta) dengan pendekatan pengukuran secara langsung dengan menggunakan data primer. Subjek penelitian semua remaja putri kelas X yang mengalami keputihan di MA AL- Fatimah Kecamatan Bojonegoro Kabupaten Bojonegoro tahun 2016 yang berjumlah 30 responden.            Hasil penelitian yang didapatkan sebanyak 25 responden remaja putri sudah bisa melaksanakan penatalaksanaan pada flour albus. Kata Kunci : flour albus,  remaja putri ABSTRACT            Adolescence develops physiological, psychosocial, cognitive, moral and sexual development. Physiological changes in adolescence are the result of hormonal activity under the influence of the central nervous system. Menarche is generally a problem for teenagers, this is because teenagers still do not know what menstruation is and how to handle it, so that the cleanliness of the genetalia area is not maintained and can lead to whitish (Soetjiningsih, 2007).This study aims to determine the management of flour albus in adolescent girls of class X in SMA AL-Fatimah Bojonegoro in 2016. The type of this research is qualitative research that is expose facto (revealing fact) with approach of measurement directly by using primary data. Research subjects of all teenage girls of class X who experienced whiteness in MA Al-Fatimah Bojonegoro District Bojonegoro District in 2016, amounting to 30 respondents.The results obtained as many as 25 female teenage respondents have been able to implement management on flour albus. Keywords: flour albus, young women
