Postharvest quality maintenance of 'Crimson Seedless' grapes by preharvest applications
Get PDFThe present study was carried out during both 2018 and 2019 growing seasons on ‘Crimson Seedless’ grape vine grown on sandy soil. Vines received water, salicylic acid 200 mg/L, chitosan 10 g/L, putrescine 5 mM, phenylalanine 400 mg/L, ascorbic acid 500 mg/L, citric acid 700 mg/L, gibberellic acid 20 mg/L, active dry yeast 15 g/L at véraison (change of color) stages and at 10 days before harvesting time. Fruit clusters were harvested when total soluble solids (TSS) reached 16%, stored at 0°C and 85–90 relative humidity for 35 days then kept 2 days at shelf life (25 ±2°C and air humidity 70 ±2). Results at harvest time showed that, salicylic acid, putrescine, gibberellic acid and yeast increased average berry weight and juice volume. Salicylic acid, chitosan, putrescine, citric acid and gibberellic acid maintained the berry adherence strength and firmness. Salicylic acid, chitosan, putrescine and phenylalanine increased berry red color, as well as berry anthocyanin, TSS and sugars content. Highest acidity content was obtained by salicylic acid, chitosan, citric acid and gibberellic acid spraying. Results after cold storage and shelf life showed that, berry weight loss decreased significantly by all chemical sprays, except phenylalanine. High maintenance of berry adherence strength and firmness occurred by gibberellic acid followed by putrescine. All chemicals reduced the unmarketable grapes except the phenylalanine.

Aktywność układu autonomicznego a dzielność wyścigowa koni arabskich czystej krwi
No full textThe aim of this study was to measure the parameters of the activity of the sympathetic and parasympathetic systems as well as the balance of the autonomic system in the context of selected indicators of horse racing performance. The study included 20 three-year-old purebred Arabians that underwent racing training. The activity of the autonomic system was measured with a Polar RS800CX device. The obtained data were analyzed in the PolarProTraine 5.0 software. The evaluation of racing performance was based on the analysis of the following indicators: total winnings, total winnings per one start, general handicap. It has been shown that the increased activity of the sympathetic system of young Arabian horses during racing training indicates their considerable emotional burden. The mares are characterized by worse results in this respect, so in their case it is worth discussing the possibility of shortening the racing season or limiting the maximum number of starts per year.Celem niniejszej pracy były pomiary parametrów aktywności układu współczulnego i przywspółczulnego oraz zrównoważenia układu autonomicznego w kontekście wybranych wskaźników dzielności wyścigowej koni. Badaniami objęto 20 trzyletnich koni arabskich czystej krwi, które przechodziły trening wyścigowy. Aktywność układu autonomicznego zmierzono urządzeniem Polar RS800CX. Uzyskane dane poddano analizie w programie PolarProTraine 5.0. Ocenę dzielności wyścigowej przeprowadzono na podstawie analizy następujących wskaźników: całkowita suma wygranych, suma wygranych przypadająca na jeden start, handicap generalny. Wykazano, że wzmożona aktywność układu współczulnego młodych koni arabskich podczas treningu wyścigowego wskazuje na ich znaczne obciążenie emocjonalne. Gorszymi wynikami w tym zakresie charakteryzują się klacze, stąd też w ich przypadku warto przedyskutować możliwość skrócenia sezonu wyścigowego lub ograniczenie maksymalnej liczby startów w roku

No full textŞiir, İslamiyet’in hem öncesinde hem de sonrasında Arap edebiyatında önemli bir yere sahip olmuştur. Kur’an-ı Kerim’in tefsiriyle ilgilenen herkes, ayetlerin anlaşılması noktasında hala şiire büyük bir önem atfetmekte ve onu temel kaynak olarak görmektedirler. Şiire verilen bu önem belli dönemlerle sınırlı olmayıp Sahabe, Tabiin ve Tebe-i Tabiîn dönemlerinden bugüne canlılığını korumuştur. Nitekim günümüzde, Kur’an ayetinin anlamı ve tefsiri hakkında sahip olunan herhangi bir görüş ya da düşüncenin desteklenmesi için şiirden nakiller yapılabilmektedir. Bu çalışma, Ebû Hayyân el-Endelüsî’nin (ö. 745/1344) hem dilbilim hem de kıraat ilmi için referans olarak kabul edilen el-Bahru’l Muhît isimli eserinde Arap şiirinin, Kur’an-ı Kerim tefsirine katkılarını ortaya koymak üzere kaleme alınmıştır. Çalışmada öncelikle Ebû Hayyân’ın hayatı üzerinde durulmuş, sonrasında izlenecek yöntem hakkında bilgi verilmiş daha sonra da şiirin, tefsirde “şahid” olarak kullanılması konusu ele alınmıştır. Önceki alimlerin bu konu hakkındaki görüşlerine de yer verilmiştir. Yine bu çalışma “şevahidin” ilk olarak nahiv açısından ele alınmıştır. Çalışmanın ilerleyen safhalarında “Taha Sûresi” özelinde Ebû Hayyân’ın tefsirinde “şahit” olarak yer alan şiirler, bahsedilen esas üzere incelenmiştir. Kur’an’daki ayetlerin i‘râb ya da tefsiri yapılırken nasıl çözümlendiği ve açıklandığı ortaya konularak nihayetinde çalışma, sonuç ve önerilerle sonlandırılmıştır

Management of granulomatous lobular mastitis: an international multidisciplinary consensus (2021 edition)
No full textGranulomatous lobular mastitis (GLM) is a rare and chronic benign inflammatory disease of the breast. Difficulties exist in the management of GLM for many front-line surgeons and medical specialists who care for patients with inflammatory disorders of the breast. This consensus is summarized to establish evidence-based recommendations for the management of GLM. Literature was reviewed using PubMed from January 1, 1971 to July 31, 2020. Sixty-six international experienced multidisciplinary experts from 11 countries or regions were invited to review the evidence. Levels of evidence were determined using the American College of Physicians grading system, and recommendations were discussed until consensus. Experts discussed and concluded 30 recommendations on historical definitions, etiology and predisposing factors, diagnosis criteria, treatment, clinical stages, relapse and recurrence of GLM. GLM was recommended as a widely accepted definition. In addition, this consensus introduced a new clinical stages and management algorithm for GLM to provide individual treatment strategies. In conclusion, diagnosis of GLM depends on a combination of history, clinical manifestations, imaging examinations, laboratory examinations and pathology. The approach to treatment of GLM should be applied according to the different clinical stage of GLM. This evidence-based consensus would be valuable to assist front-line surgeons and medical specialists in the optimal management of GLM.Improving the Ability of Diagnosis and Treatment of Difficult Diseases [ZLYNXM202009]This work was supported by Improving the Ability of Diagnosis and Treatment of Difficult Diseases (ZLYNXM202009)
