Cherry Lethal Yellows and Decline Phytoplasmas
No full textCherry is an important fruit crop for which severe decline
symptoms associated with the presence of phytoplasmas has
been reported in the past years. A cherry decline, termed
“leptonecrosis,” was first reported in Emilia region of northern
Italy in the early 1930s. An outbreak of a
lethal yellows disease on Chinese cherry in the Sichuan
province of China in 1989 caused severe losses to the local
cherry industry. Electron microscopy
study of diseased tissues and disease remission resulting from
tetracycline treatment of infected plants suggested that the
cherry lethal yellows (CLY) disease may be caused by a
phytoplasma . Based on the phylogenetic
analysis of the 16S rRNA gene, RFLP analysis of ribosomal
protein gene sequences and Southern hybridization analysis of
total genomic DNA using selected DNA probes derived from
the Elm Yellows (EY) phytoplasma (group 16SrV, subgroup
16SrV-A), it was proposed that the CLY phytoplasma belongs
to the elm yellows phytoplasma group (16SrV), and represents
a new subgroup, 16SrV-B, distinct from other members of 16S
rRNA group V or 16SrV.
A recent study showed the presence of 16SrV-B
phytoplasmas in severely declining cherry trees in northern
Italy. More recently phytoplasmas
belonging to two ribosomal groups (stolbur, 16SrXII-A and
clover yellow edge, 16SrIII-B, respectively) were identified in
cherry plants showing a quick dieback before the harvesting
season, this disease is named decline.
The symptoms associated with the diverse phytoplasmas in
Italy do not differs from each other and are quite similar to the
CLY described in China
Peach latent mosaic viroid in naturally infected sweet cherry trees in southern Italy
No full textPeach latent mosaic viroid (PLMVd) was found in naturally infected sweet cherry trees grown in commercial orchards in southern Italy. The viroid was detected in nucleic acid extracts of symptomless leaves by molecular hybridization with a PLMVd cRNA probe. The viroid was transmitted by grafting from sweet cherry to peach seedlings and identified in peach by molecular hybridization

No full textRole of Trans-Anal Endorectal Pull-Through in Complicated Hirschsprung’s Disease: Experience in 18 Patient.
No full textBackground/Purpose: In Hirschsprung’s disease (HD) redo pull-through (PT) is indicated for
anastomotic complications and for persistent aganglionosis after previous definitive surgery. This study
was undertaken to evaluate the role of transanal approach to redo PT procedure in the management of
complicated cases of HD over the last 7 years.
Patients and Methods: Between November 1998 and September 2005, 225 patients with HD were
operated using the transanal endorectal PT (TEPT) approach. Eighteen patients had a redo PT owing to
persistent aganglionosis.
The present study evaluates the role of TEPT approach in patients with persistent aganglionosis (n = 18).
Three patients needed a colostomy (n = 2) or ileostomy (n = 1) before the final operation. All the 18
patients underwent transanal mobilization (TEPT) of the colon. Six patients required additional
mobilization of the proximal colon (n = 4) and the ileum (n = 2) during the redo PT operation.
Results: Median follow-up was 43 months (range, 3-72 months). Sixteen patients have had a good
outcome with stool pattern 1 to 4 times daily. One patient had obstructive symptoms for 4 months
postoperatively but then settled. One patient has occasional soiling.
Conclusions: In this series, TEPT and posterior midline split of the muscle cuff were used with good
results. This has the advantage of avoiding injury to the pelvic muscles and nerves. The TEPT approach
is combined with transabdominal mobilization of the intestine depending on the length of the
aganglionic segment. The outcome has been favorable, but long-term follow-up is necessary for full
assessment of those patients
GENEALOGI PENAFSIRAN AYAT-AYAT TAUHID MARWAN HADIDI BIN MUSA DALAM KITAB HIDAYATUL INSAN
No full textPembahasan mengenai konsep tauhid dalam Islam sejak masa awal telah melahirkan perbedaan pemahaman yang memicu munculnya berbagai aliran. Perbedaan ini tercermin pula dalam penafsiran ayat-ayat tauhid di al-Qur’an yang dilakukan para mufassir dengan pendekatan dan sudut pandang beragam. Namun, sebagaimana sebuah penafsiran, tentu melalui proses transmisi dan transformasi dari proses tafsir sampai pada hasil akhir berupa produk tafsir. Dari sinilah tafsir dapat diasumsikan memiliki keterhubungan dengan tafsir lainnya, terutama dengan tafsir yang lahir sebelumnya. Oleh karena itu, perlu untuk melihat sebuah produk tafsir dari sudut pandang genealogi sebab sebuah produk tafsir tidak akan bisa berdiri sendiri tanpa terhubung atau dipengaruhi oleh tafsir-tafsir sebelumnya. Penelitian berfokus pada penafsiran ayat-ayat tauhid dalam kitab Tafsir Hidayatul Insan karya Mawan Hadidi bin Musa. Metode yang digunakan dalam penelitian ini yaitu metode kualitatif dengan menggunakan teori genealogical tradition dari Walid Saleh dan dilengkapi dengan analisis sosial. Data yang dikumpulkan berupa data yang memuat informasi Marwan Hadidi bin Musa dan kitab Tafsir Hidayatul Insan, data tersebut berupa informasi mengenai "konteks tafsir" dan juga informasi mengenai "konteks non-tafsir". Hasil dari penelitian ini menunjukkan bahwa dalam membahas ayat-ayat tauhid, Marwan Hadidi bin Musa cenderung memberikan penjelasan tauhid dalam tiga bagian, yaitu uluhiyyah, rububiyyah, dan asma' wa sifat. Dari sudut pandang genealogi, keterpengaruhan Marwan Hadidi bin Musa dalam menafsirkan ayat-ayat tauhid dalam konteks tafsir bahwa penafsirannya menunjukkan keterhubungan dengan tradisi tafsir klasik, khususnya melalui rujukan pada Tafsir Ibnu Katsir, Tafsir Jalalain, dan Tafsir Karimir Rahman fi Tafsir Kalamil Mannan, baik dalam pola penyajian maupun isi penafsiran. Sedangkan dalam konteks non tafsir, penafsirannya dipengaruhi oleh pendidikan informal yang ia peroleh dari guru-gurunya yang berafiliasi dengan akidah Ahlussunnah wal Jama’ah, serta kondisi sosial yang membentuk cara pandangnya

No full textEvaluating Web Applications Testability by Combining Metrics and Analogies
No full textThis paper introduces an approach to describe a Web application through an Object-Oriented model and to study application testability using a quality model focused on the use of Object-Oriented metrics and software analogies analysis. The proposed approach uses traditional Web and Object-Oriented metrics to describe structural properties of Web applications and to analyze them. These metrics are useful to measure some important software attributes, such as complexity, coupling, size, cohesion, reliability, defects density, and so on. Furthermore, the presented quality model uses these Object-Oriented metrics to describe applications in order to predict some software quality factors (such as test effort, reliability, error proneness, and so on) through an instance-based classification system. The approach uses a classification system to study software analogies and to define a set of information then used as the basis for applications quality factors prediction and evaluation. The presented approaches are applied into the WAAT (Web Applications Analysis and Testing) project
